Objective Evaluation of the ability of autogenous Platelet Rich Fibrin (PRF) and Zinc Oxide Nanoparticles (ZnONPs) to repair critical-sized ulnar defects in rabbits based on radiographic assessment. Design Randomized controlled study. Animals Twenty-four healthy male white New Zealand rabbits with an age of 6.0 ± 0.3 months and weight of 2.5 ± 0.29 Kg were used. Procedures A 12 mm defect was created in the diaphysis of the right ulnae in allrabbits,then the rabbits were randomly allocated into three groups (8 each): Control group, (the defect left for healing without grafts), platelets rich fibrin group (PRF group, the defect filled with PRF) and combination group (PRF/ZnONPs group, the defect filled with both PRF and ZnONPs). Healing capacity between the groups was evaluated by immediate postoperative radiographic assessment and subsequently at the first and the second postoperative months. Results Statistical analysis showed significant differences in the radiographic healing score between the groups (P = 0.000) at all-time points (P = 0.000- 0.003) during the study. Rabbits in the combination group showed the highest radiographic healing scores followed by the PRF group meanwhile, the Control group showed minimal radiographic healing scores. Conclusion and Clinical Relevance The addition of ZnONPs to PRF can accelerate the healing of ulnar critical-size defects in rabbits.

Bone Scaffold is a three-dimensional porous construction which provides support to promote natural cell growth in damaged or broken section of bone. In recent years researchers from various departments like biomedical, mechanical, orthopedics, have shown significant interest in adopting ‘Bone Scaffolds’ as a promising treatment for bone defects. ‘Bone Scaffold’ is a honeycomb-like architecture composes of bio-compatible material having grater advantages over current grafting solution. In this paper, the authors try to review the available e-articles in an organized way on the bone scaffold in the field of biomedical implants with 3D printing. The selected literature mainly focuses on the biocompatible material and various advanced manufacturing methods used for manufacturing / preparing of bone scaffolds. This article tries to padding the gap between theoretical and actual implementation of ‘Bone Scaffolds’ by properly analyzing selected research and allowing future opportunities for reinventing the new possibilities in the field of biomedical.

Background The mammary glands are the second most common tumor development site in female dogs. One of the ways of staging such tumors is to evaluate the presence or absence of distant metastasis, including in bone marrow. Such findings in human medicine are associated with poor survival of women with breast tumors. However, in veterinary medicine, this clinical staging is used more for patients with lymphomas and mastocytomas. Studies using bone marrow biopsies as a staging method for mammary tumors are scarce. Objectives The present study was to evaluate mammary lesions and bone marrow in 23 female dogs, searching for disseminated tumor cells or metastatic foci. Results: Grade I carcinoma in mixed tumors was the type most observed (22.4%), and there was no statistical difference in relation to tumor size or presence of metastasis in lymph nodes. In the bone marrow of one female dog with carcinosarcoma (4.35%), there was cytoplasmic marking of a probable disseminated tumor cell of epithelial origin, and immunohistochemical evaluation showed presence of cytokeratin-19 antibodies. None of the female dogs presenting reduced cellularity or medullary fibrosis, confirmed through Masson’s trichrome technique, had cell marking in immunohistochemical analyses. Conclusions Bone marrow evaluation can be used as a staging method for mammary gland tumors in female dogs, since disseminated tumor cells present the potential to become secondary lesions and to disseminate to distant foci, thereby causing tertiary metastases over an indeterminate period of time.

Background During the last two decades, the polymorphism of Angiotensin-Converting Enzyme (ACE) gene has been extensively studied among different human populations. In humans, several studies have shown the relationship between this polymorphism and the risk of many serious diseases with a heavy burden of health in developing countries. After analyzing the polymorphism in the population, the present study was also concerned with the investigation of an eventual association between hypertension, stroke, cancer prostate and I/D polymorphism of the ACE gene. Materials and Methods Our study population included 163 Baka (pygmy) and 158 Fang (Bantu) from Gabon to evaluate the polymorphism in the country. Concerning the diseases, we included 105 patients and 120 controls for hypertension, 37 patients stroke matched with 50 controls and 97 patients with prostate cancer were recruited. All participants in the study were genotyped for the ACE I/D polymorphism obtained by polymerase chain reaction amplification on genomic DNA. Results Our analysis showed that the ACE D allele DD genotype frequencies were highest of all the data so far in human populations. We obtained a frequency of 0.138 for I allele and 0.862 for D allele among pygmy and the frequencies of 0.313 and 0.687 respectively for the I and D alleles. This difference was significant (p<0.05). In patients, we revealed the predominance of D allele and DD genotype for hypertension (0.27 for I allele and 0.73 for D allele), for stroke (0.15 for I allele and 0.85 for D allele) and 83% of individuals with cancer prostate carry the D allele. D allele and DD genotype are associated with risk to hypertension whereas allele I seem protective at the occurrence of stroke (p<0.05 between healthy and controls). Conclusion We show that the D allele and DD genotype were higher in this population. Also theses two signatures may be associated at genetic risk of hypertension, stroke and prostate cancer in this country deprived of human resources for quality care of many patients.

Aim To study the chondroplasty efficacy of the bone matrix obtained using an original technology in restoring cartilage defect of the knee joint. Material and Methods Marginal defects were modeled on the surface of the distal end of the femur in 40 adult male Wistar rats. The bone matrix obtained using an original technology was implanted in the damaged area in animals of the experimental group. Material was investigated by means of light microscopy, transmission and scanning electron microscopy, and electron probe X-ray microanalysis. Results It was found that the bone matrix implanted did not cause an immune rejection reaction, activated reparative chondrogenesis for a prolonged period. In the area of articular cartilage lesion, the regenerate acquiring cellular and histochemical characteristics of the hyaline cartilage tissue was formed. The chondroinductive properties for the bone matrix were ensured by localized growth factors and morphogenetic proteins released during osteoclastic resorption. Conclusion The application of the bone matrix as a stimulator of chondrogenesis is theoretically reasonable and has a good perspective in treatment of damages and diseases of the articular cartilage.

Background Free vascularised fibular bone grafting has gained popularity in various Orthopaedic and Oral & maxillofacial reconstructive surgeries. The objective of the present study was to identify the morphology and topography of nutrient foramina of fibula and to determine the foraminal index (FI) of the fibula using a more surgeon friendly bony landmark. Methods The study comprised examination of 100 fibulae specimens. Each bone was divided into 03 parts and topographical analysis was performed on each section. The nutrient foramina were identified macroscopically using size 24-gauge needle. Modified Hughes formula was used to calculate the foraminal index using distance of foramen (DF) from distal end which is easier to palpate in living human beings, total length of fibula (TL); and the formula was DF/TL x100. Results With respect to fibulae, 98% had single foramen and foramen was absent in 2%. The mean foraminal index (FI) was 56% for fibulae using modified Hughes’ formula. The majority of the fibulae showed nutrient foramen in the middle 3rd in relation to distal end of fibula. Conclusion The study provides information on the morphology of nutrient foramina in relation to easily palpable landmark on living human beings, which can provide guidance to surgeon while performing microvascular bone transfer procedures.

Objective The current clinical case series assess the clinical outcome of the use of low-level laser in the treatment of painful pediatric fractures not solidly consolidated and re-modelled after casting for a standard of 4-6 weeks Materials and Methods The patient cohort consisted of 17 consecutive unselected patients in pediatric age group with delayed fracture consolidation and/or undesirable angulation despite casting for a standard period of 4-6 weeks in whom the parents refused any surgical intervention and/or bone grafting options. All subjects were referred from other medical centers after inadequate healing of the fracture ends upon repeating the x ray after the cast was off at the 4-6 weeks mark. Low-level laser therapy (LLLT) on alternate days for 8weeks in upper limb fracture cases, and 12 weeks in lower limb fracture cases were administered with a view of enhancing bone healing and/or re-modelling since both previous clinical and basic science studies on LLLT showed a stimulatory effect on fracture healing. Results All patients had solid union, mean time for union for upper and lower limb fractures were 6 and 10 weeks respectively. The calculated p value is statistically significant at p < 0.05. No patient defaulted follow up. All parents were satisfied with the clinical and radiological result of the LLLT treatment. Conclusion LLLT was found not only to enhance bone healing potential but in fact improved bone re-modelling when used in the proper wavelength and energy density in pediatric upper and lower limbs fractures, thereby also rapidly resolve the intolerable pain in paediatric fracture population

An anatomical variant of the Stafne bone cavity (SBC) located in the right subcondylar region of the mandible is presented. Such an occurrence of the SBC in this region near the parotid gland is considered rare and poses a diagnostic challenge for the dentist and radiologist. Knowledge of head and neck clinical anatomy and imaging studies such as plain film panoramic radiographs and cone beam CT scans can assist the clinician in arriving at a correct definitive diagnosis without surgical intervention.

Methotrexate (MTX) is an anti-metabolite in cancer chemotherapy and is associated with various toxicities assigned to inflammation and oxidative stress. The present study was undertaken to corroborate the therapeutic effects of bone marrow mesenchymal stem cells (BM-MSCs) and adipose-derived mesenchymal stem cells (AD-MSCs) in MTX-induced intestinal toxicity in experimental animals as compared with dexamethasone (Dex). Rats were divided into five groups: I-Normal control group, II- MTX (14 mg/kg, as a single dose/week for 2 weeks), III & IV- BM-MSCs & AD-MSCs (2 × 106 cells/rat, 1 week after last dose of MTX), respectively, plus V- Dex (0.5 mg/kg/ for 7 days, 1 week after last dose of MTX). MTX induced marked intestinal elevation of interleukin-6, total oxidant, and nitrite/ nitrate, caspase-3 contents and myeloperoxidase activity, along with the reduction of reduced glutathione content and catalase activity. In conclusion, the positive modulation of MTX toxicity could be attributed to the free radical scavenging, anti-inflammatory and antiapoptotic potential of BM-MSC and AD-MSCs which will possibly make them as remarkable hopeful for the treatment of intestinal injury.

Poor bone health is the primary health issue, which leads to significant health problems, stress and worsening the patients' quality of life. The potential of The Trivedi Effect®- Biofield Energy Healing on vitamin D3 as a test item (TI) and DMEM on MG-63 cells was investigated. The test items were treated with The Trivedi Effect® by Mahendra Kumar Trivedi and divided as Biofield Energy Treated (BT) and untreated (UT) test items. An increase in ALP activity, collagen levels, and bone mineralization was considered as the biomarker for bone health. MTT data showed that the test samples observed nontoxic in the tested concentrations. The level of ALP was significantly increased by 832.9% and 209.4% in the UT-DMEM+BT-TI and BT-DMEM+UT-TI groups, respectively at 10 µg/mL, while 222.9% increase in the BT-DMEM+BT-TI at 1 µg/mL compared to the untreated group. Collagen was significantly increased by 487.7% and 544.5% in the BT-DMEM+UT-TI and BT-DMEM+BT-TI groups, respectively at 100 µg/mL, while 116.2% at 1 µg/mL in UT-DMEM+BT-TI compared to the untreated group. Moreover, the percent of bone mineralization was significantly increased in the UT-DMEM+BT-TI and BT-DMEM+UT-TI groups by 344.9% and 149.7%, respectively at 50 µg/mL, while 183.6% in the BT-DMEM+BT-TI group at 100 µg/mL compared to the untreated group. Thus, the role of Biofield Energy Treated vitamin D3 and DMEM in order to control osteoblast function and its direct effects on bone mineralization can be used to improve bone disorders.

The chemical and structural similarities of calcium orthophosphates (abbreviated as CaPO4)to the mineral composition of natural bones and teeth have made them a good candidate for bone tissue engineering applications. Nowadays, a variety of natural or synthetic CaPO4-based biomaterials is produced and has been extensively used for dental and orthopedic applications. Despite their inherent brittleness, CaPO4 materials possess several appealing characteristics as scaffold materials. Namely, their biocompatibility and variable stoichiometry, thus surface charge density, functionality and dissolution properties, make them suitable for both drug and growth factor delivery. Therefore, CaPO4, especially hydroxyapatite (HA) and tricalcium phosphates (TCPs), have attracted a significant interest in simultaneous use as bone grafts and drug delivery vehicles. Namely, CaPO4-based three-dimensional (3D) scaffolds and/or carriers have been designed to induce bone formation and vascularization. These scaffolds are usually porous and harbor various types of drugs, biologically active molecules and/or cells. Over the past few decades, their application as bone grafts in combination with stem cells has gained much importance. This review discusses the source, manufacturing methods and advantages of using CaPO4 scaffolds for bone tissue engineering applications. Perspective future applications comprise drug delivery and tissue engineering purposes.

Purpose of Study: To study reparative osteogenesis and tissue integration characteristics for implanting three-dimensional mesh structures of titanium nickelide into a bone cavitary defect. Material and Methods: The authors modeled cavitary defects of femoral metaphysis experimentally in Wistar rats divided into an experimental group and control one. The study duration was 60 days in total. The methods of radiography, those of light and electron microscopy, X-ray electron probe microanalysis used. Results: Under implantation the defect was filled with cancellous bone the volumetric density of which more than 1,5-fold exceeded control values (р < 0.001). The implant had biocompatibility, osteoconductive and osteoinductive properties, it stopped inflammatory processes. The membrane protective barrier which prevented connective tissue sprouting was formed on the implant surface in the defect periosteal zone. The osteointegrative junction was formed being persisted up to the end of the experiment. Reparative osteogenesis was performed by direct intramembranous and apposition type. Conclusion: The implant of three-dimensional mesh titanium-nickelide structures has marked osteoplastic properties, and it can be successfully used in orthopedic surgery.

Bone quality is difficult to assess but the skeletal bone condition is reflected in mandibular trabecular bone, which is well imaged in periapical dental radiographs. The aim of this 12-year prospective cohort study was to test if marginal mandibular bone loss differs in women with varying trabecular bone structure. The sample consisted of 460 women (aged 38, 46, and 54 years) from the prospective population study of women in Gothenburg, Sweden. Marginal bone loss was assessed according to a five-graded scale in two surveys 12 years apart, and the mandibular bone structure was evaluated visually as sparse, mixed, and dense. The results showed that marginal bone loss was significantly correlated to mandibular bone structure (r= 0.20; p<0.001 at baseline, and r= 0.17; p<0.001 after 12 years). Significant differences in marginal bone loss between trabeculation groups were found, with the largest loss in the group with dense trabeculation. Age, smoking, number of missing teeth and trabecular bone structure explained 20-28% of the variation in marginal bone loss. The conclusion was that women with dense trabecular bone in the mandible suffered a stronger periodontal bone destruction when negative events occur, than the women with sparser trabeculation.

Objectives: To clarify the role of trace elements in the etiology and the pathogenesis of the chondrosarcoma, a non-destructive neutron activation analysis with high resolution spectrometry of long-lived radionuclides were performed. Methodology: The silver (Ag), cobalt (Co), chromium (Cr), iron (Fe), mercury (Hg), rubidium (Rb), antimony (Sb), selenium (Se), and zinc (Zn)mass fractions and Co/Zn, Cr/Zn, Fe/Zn, Hg/Zn, Sb/Zn, Co/Rb, Cr/Rb, Fe/Rb, Hg/Rb, Sb/Rb, and Se/Rb mass fraction ratios were estimated in normal bone samples from 27 patients with intact bone (12 females and 15 males, aged from 16 to 49 years), who had died from various non bone related causes, mainly unexpected from trauma, and in tumor samples, obtained from open biopsies or after operation of 16 patients with chondrosarcoma ((3 females and 13 males, 8 to 65 years old). The reliability of difference in the results between intact bone and chondrosarcoma tissues was evaluated by Student’s t-test. Key Results: In the chondrosarcoma tissue the mass fractions of Co, Fe, and Se are significantly higher while the mass fraction of Rb is lower than in normal bone tissues. Moreover, significantly higher Co/Zn, Fe/Zn, Co/Rb, Cr/Rb, Fe/Rb, Sb/Rb, and Se/Rb mass fraction ratios are typical of the chondrosarcoma tissue compared to intact bone. In the chondrosarcoma tissue many correlations between trace elements found in the control group was no longer evident. Major Conclusions: In chondrosarcoma transformed bone tissues the trace element homeostasis is significantly disturbed.

Hip fractures, which remain an immense public health concern, have been subject to study and prevention efforts for many decades, but with limited success in averting either incident, second or subsequent hip fractures, commonly attributed to a combination of age related proclivity to fall, low bone and muscle mass. This review examines second hip fracture incidence rates and determinants of this serious functionally debilitating injury as observed over time remains a current 2026 public health concern. It specifically explores if more preventive efforts are currently warranted in this regard, and in what respect, if indeed, more frail older adults are living longer, but may be in excessively poor health, fearful of moving or falling, malnourished, weak with poor balance, or depressed. Based on what is published, it is concluded 1) second hip fracture incidence rates remain considerable, especially among those who are frail with osteoporotic bone disease, poor vision, heart/or cognitive conditions, plus those with muscle deficits of the lower limb, live alone and have a falls history; 2) studies to identify possible mitigation approaches appear promising in this regard, along with more routine efforts to minimize falls risk and bone attrition.

For the edentulous patient, dental implant therapy is the accepted treatment to replace one or more missing teeth as implant survival rates are greater than 90%. Unfortunately, surgical removal of dental implants occurs for a variety of reasons. As human studies are limited, this case report provides an opportunity to evaluate the peri-implant characteristics in a dental implant removed from a patient using histology. In our patient, the implant was removed three years after completion of the prosthetic phase due to fracture of the abutment that could not be removed from the implant. Histological examination of the implant revealed mature lamellar bone in direct contact with the implant surface. Histomorphometric evaluation revealed a bone-to-implant contact (BIC) of 73.6%.

The aim of this article is to present alternative possibilities for corrective intervention using corticobasal implants, following the failure of treatment with two stage implant in cases of extensive edentulism, multi-segmented edentulism, and the development of peri-implantitis 1 at the level of these implants. For this purpose, a case was selected involving a patient treated with two stage implants in a multi-segmented manner, in the distal regions of the maxilla and mandible, where the implants were affected after 12 years by peri-implantitis in proportions ranging from 20% to 100% in different areas of bone, with a predominance in the vestibular area. The decision was made to remove the affected two stage implants, as well as the remaining deciduous teeth, with or without periodontal conditions, but whose position on the arch made improperly rehabilitation, both functionally and aesthetically impossible, and made the second rehabilitation with polished corticobasal and compressive implants in immediate loading 2. Function and aesthetics of the gnathological apparatus were restored through definitive fixed metal-ceramic prosthetics on the support of corticobasal and compressive implants within 4 days from the beginning of the treatment, with the result being monitored over a period of 3 years and 3 months, and this evaluation is to continue over time. From a surgical perspective, for secondary rehabilitation with polished corticobasal and compressive implants, strategic positions in the maxillary and mandibular bones were used as follows: the fusion area of the maxillary bone with the sphenoid bone, the nasal cortex, the sinus cortex the lingual cortex distal to the mylohyoid line, and the interforaminal mandible area.34 These areas correspond to methods described in Consensus Number 6 in the IF The Foundation of Knowledge 5. In conclusion, the treatment with corticobasal, compressive polished implants is successful even in the case of a difficult clinical scenario like the one described for this patient 6. The reduced treatment time, along with the absence of the need for sinus lifts or bone grafts, makes it the ideal solution in any situation. The use of corticobasal implants, with fixation in the second/third cortical layer and an immediate loading protocol, should represent the primary solution in treating cases with poor bone representation, and no only as a “Corrective Intervention with Corticobasal® Implants”7.

Background Oxaliplatin, a widely used chemotherapeutic agent, is associated with hematologic toxicities such as anemia, leukopenia, and thrombocytopenia. Despite their clinical relevance, the molecular mechanisms underlying lineage-specific bone marrow suppression remain poorly understood. Methods We administered oxaliplatin to mice over eight weeks and performed RNA-sequencing (RNA integrity >8) on bone marrow alongside peripheral blood analysis and cytokine profiling. Transcriptomic data were analyzed to identify differentially expressed genes (DEGs) and enriched pathways. For that, we applied a thematic Gene Ontology (thematicGO) enrichment method that groups GO terms into biologically meaningful categories, such as hematopoietic lineage disruption, cell cycle arrest, and cytokine signaling. Results Oxaliplatin induced broad transcriptional suppression of erythropoiesis and lymphopoiesis, with 3,691 DEGs identified (FDR<0.05, |FC|>1.5). Upregulation of Cdkn1a and downregulation of E2f2 suggest G1/S cell cycle arrest, correlating with repression of key erythroid maturation genes (e.g., Spta1, Slc4a1, Alas2) and hemoglobin subunits (Hba-a1/2, Hbb-bs/t). Despite a ~3000-fold increase in renal Epo expression, bone marrow Epor was reduced, indicating erythropoietin resistance. B and T cell markers were also significantly downregulated, signifying a collapse in adaptive immunity. Notably, neutrophil populations were largely spared. Cytokine analysis in plasma revealed a pro-inflammatory shift with elevated TNF-α and reduced TGF-β, potentially exacerbating hematopoietic dysfunction. Conclusions Oxaliplatin induces a lineage-dependent suppression of hematopoiesis, driven by coordinated cell cycle arrest, metabolic stress, and disrupted cytokine signaling. RNA-seq analysis enabled integration of transcriptomic findings into coherent biological themes. These findings provide mechanistic insights into oxaliplatin’s hematologic toxicity linking bone marrow failure (potentially reversible) via interconnected inflammatory and metabolic pathways and may inform therapeutic strategies to minimize or restore myelosuppression in cancer patients.

This narrative literature review investigates the clinical feasibility of maxillary sinus lift using the lateral window (or traumatic) technique, employing a grafting material composed of hydroxyapatite associated with beta-tricalcium phosphate. The study is based on the premise that bone resorption and sinus pneumatization—common in edentulous posterior maxillae—pose a challenge to achieving primary stability during dental implant placement. Given the limitation imposed by reduced residual bone height, bone-grafting surgical techniques become necessary to enable implant-supported rehabilitation. The objective of this work is to analyze, through a literature review, the efficacy of combining synthetic biomaterials as an alternative to autogenous bone grafts, which are considered the gold standard in implant dentistry. A bibliographic search was conducted in the PubMed and LILACS databases and through the VHL portal, prioritizing articles addressing the biological properties of alloplastic grafts, the indications of the lateral window technique, and the clinical success rates of implants placed in previously grafted areas using such materials. The findings demonstrated that hydroxyapatite associated with beta-tricalcium phosphate exhibits favorable osteoconductive characteristics, such as adequate porosity and gradual resorption, while allowing the formation of viable bone within a clinically acceptable timeframe. The combination of these materials eliminates the need for a second surgical site, reduces morbidity, and maintains treatment predictability. It is concluded that the lateral window technique associated with synthetic biomaterials is a safe and effective alternative for patients with maxillary bone atrophy, capable of promoting suitable bone beds for dental implant placement and stabilization, with lower surgical risk and satisfactory clinical outcomes.

This mini review examines the potential efficacy of applying electromagnetic field therapy for purposes of reducing osteoarthritis pain and other related disease features such as frailty, muscle sarcopenia, obesity, bone loss and fragility, and cartilage derangements and degradation in the older adult. Based on selected English language literature published largely on PUBMED between January 2000 and October 2025, papers describing the impact and potential synthetic and disease modifying impact of electromagnetic stimuli are explored. These data reveal a high degree of promise in fostering joint tissue reparative efficacy trends post electromagnetic stimulation. Its usage may allay the extent of the disease and its degree of disablement, while facilitating function.

Depending upon the species, the brainstem auditory evoked potential (BAEP) consists of four or five major high frequency components. According to longstanding doctrine, each wave represents the sequential activation of successively higher nuclei and tracts from the 8th (auditory) nerve to the midbrain (inferior colliculus). Although this conceptual framework has acquired the status of near dogma, surprisingly little evidence exists in support. In the present analysis, a new interpretation of the electrogenesis of the BAEP is proposed which is simpler although it retains skeletal elements of the older explanation. The revised model is mostly derived from two distinct sources. In the first, the timing of the BAEP waves is compared with that of cortical activity for a range of mammals including humans, monkeys, cats, rats and guinea pigs. It is demonstrated that for each of these, the conduction time of the acoustic signal to the cortex from the putative midbrain component (wave IV or V) is so unrealistically long that it implies that the entire waveform must arise in the peripheral pathways of the auditory system. In the second, a retrospective analysis is made of click repetition rates on the BAEP using extradural electrodes. It was shown that at high rates of stimulation (about 100/sec), the behavior of the waveform is almost totally at variance with the expectations of the conventional model. The essence of the revised conception is that all BAEP waves are just variations of the compound action potential of the 8th nerve, albeit generated or regenerated via separate routes and different methods. Such an explanation would thereby account for their near uniform sharp morphology as well as creating the impression of a composite neuronal response. More specifically, in the case of a four component BAEP, wave I is assumed to be generated by the normal air conduction route in an identical manner to the conventional explanation. In contrast, wave ll is assumed to be generated via bone conduction in the temporal skull thereby bypassing the transduction process in the middle ear. Wave lll is assumed to be generated by the first echo of the bone-conducted sound wave. Likewise, the second rebound within the temporal bone serves as the stimulation to evoke wave lV. As the energy of the auditory stimulus gradually dissipates, it may still continue to generate a train of lower amplitude potentials. It is concluded that the BAEP may contain little or no brainstem or midbrain activity and therefore the term BAEP may be a misnomer. A more appropriate epithet might therefore be the auditory nerve evoked potential or ANEP.

Background and Objectives Platelets are small, anucleate blood cells produced in the bone marrow, primarily involved in blood coagulation. Platelet concentrate is a vital blood product with extensive applications. However, its short lifespan and limited donor availability pose global challenges. This study aimed to follow the trend of platelets 5 during days of storage. Material and Methods We studied on 40 platelet bags and analyzed glucose levels, lactate dehydrogenase (LDH), bacterial culture, and apoptosis using flow cytometry with Annexin V-PI over three consecutive days (first, third, and fifth) post-blood collection. Data were analyzed using SPSS. Results No significant correlations were found between age, blood group, or gender and the variables studied. No bacterial growth was detected. Glucose levels decreased significantly from day 1 (382 mg/dl) to day 5 (298 mg/dl). The average platelet apoptosis increased significantly from 3.65% on day 1 to 9.06% on day 5. Significant correlations were observed between glucose levels and apoptosis on days 3 (p<0.05) and 5 (p<0.01). No correlation found between LDH and apoptosis or necrosis, although a significant relationship between necrosis and apoptosis was noted on day 5 (p=0.003). Conclusion These findings suggest that while demographic factors do not influence the studied variables, the significant decrease in glucose levels correlates with increased platelet apoptosis over time, highlighting potential metabolic interactions that warrant further investigation. Highlights 1. The study revealed subtle variations in metabolic markers related to donor demographics, particularly gender and age. Understanding these differences can inform targeted donor selection strategies to optimize platelet quality. 2. A significant negative correlation was found between glucose levels and apoptosis rates, indicating that as glucose decreases, platelet viability declines. This relationship highlights the need for careful monitoring of glucose levels during storage to maintain platelet function. 3. Fluctuations in lactate dehydrogenase (LDH) levels were correlated with increasing rates of apoptosis, suggesting that LDH could serve as a valuable biomarker for assessing platelet quality throughout the storage period. This finding could lead to improved storage protocols and enhanced transfusion safety.

Objective The repair of the tympanic membrane has been attempted with large variety of synthetic, homologous and autologous tissue; however, temporalis fascia and cartilage-perichondrium are used most commonly today. Study Design This is a prospective study of patients confirmed to have CSOM and operated during the years of 2012-2013 at Al Nahdha Hospital, Muscat, Sultanate of Oman. The patients were followed up postoperatively at which we compared the graft success rate and level of hearing improvement. Setting ENT clinic at Al Nahda hospital Subjects Patients who presented to the ENT clinic at Al Nahda hospital, operated in the period between 2012 and 2013, diagnosed as CSOM and meeting our inclusion criteria. Methods We compared the outcome of the repair of the tympanic membrane perforation using temporalis fascia graft versus cartilage perichondrium grafts. Results 100% of the cartilage-perichondrium group showed a successful graft uptake in comparison to 98.9% in the temporalis fascia. Our data did not show significant differences in the average air bone gap change in both groups. Conclusion Both cartilage-perichondrium and temporalis fascia provide viable autograft material. Both achieve comparable and excellent graft uptake. Completion of our study is needed to study the hearing restoration in both groups.

Vitamin D deficiency is known to affect bone healing 1. In this case report, the potential link between vitamin D, calcium, and phosphorus deficiency and periapical lesions is explored, offering fresh insights into the complex relationship between systemic health and dental pathology. This pathology is caused by a mutation in the PHEX gene on chromosome X, which encodes a protein necessary for vitamin D synthesis and phosphate reabsorption, which are essential for the mineralization of bone and teeth 23. A 25-year-old man with rickets and vitamin D deficiency presented to our clinic with recurrent abscesses in multiple teeth. Radiographic imaging revealed periapical lesions on multiple teeth with advanced endo-perio lesions on teeth 26 and 16, and a negative cold test on all his teeth. Despite successful endodontic treatment, the patient’s compromised metabolic healing raised concerns about the prognosis. This case report highlights the intricate interplay between vitamin and mineral deficiencies and dental health, emphasizing the need for cautious management and long-term follow-up.

This article has been retracted on April 10, 2025. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2997-2086.jfs-25-5857) Myelomeningocele (MMC), a class of spina bifida is a type of neural tube defect. According to the U.S. Centers for Disease Control and Prevention, each year approximately 1,400 babies born in the United States have spina bifida. The disease manifests with the lack of skin and bone covering the caudal part of the spinal cord. The patient developing such a condition often develops lifelong impaired lower limb mobility accompanied by hydrocephalus, and urinary and bowel incontinence. The available interventions include prenatal and postnatal surgery to fuse the dura. Prenatal surgery performed before 26 weeks of gestation reduces the risk of death or the need for ventriculoperitoneal shunting. It also enhanced results on a comprehensive index for mental and motor function. When compared to postnatal surgery, prenatal surgery reduces the manifestation of several secondary outcomes, including the degree of hindbrain herniation seen in the Chiari II malformation. Stem cell therapy for MMC on animal models of chick, ovine, and rodents with reported cases 15/63, 15, and 136, respectively, using human Embryonic Stem Cells (hESCs), Neural Stem Cells (NSCs), Mesenchymal Stem Cells (MSCs) showed significant coverage of MMC defect and slight neurogenesis was also observed. With an understanding of medical literature about in-utero regenerative capacity, it is to be appreciated that placental stem cells surgically seeded within a biocompatible scaffold of the cell patches can play a part in alleviating the spinal cord manifestation associated with MMC. Documented animal studies show that incorporating Placental Mesenchymal Stem Cells in prenatal surgery has reported improved neurogenesis and lower limb mobility. In an ovine myelomeningocele model, the development of in-utero myelomeningocele repair with human Placental Mesenchymal Stem Cells seeded onto an extracellular matrix (PMSC-ECM) enhances motor findings. The clinical trial for the first stem cell therapy on human subjects known as the “CuRe Trial: Cellular Therapy for In Utero Repair of Myelomeningocele.” is expected to be finished by 2030. So far, the cases undergoing treatment have shown significant leg movement and a greater degree of bowel and urinary control. This FDA-approved clinical trial is envisioned to be the future of treating MMC.

Caudal injection is a type of epidural injection that is administered to the lower back to reduce pain and inflammation. The injection contains a steroid medication that is injected into the lower part of the epidural space, which surrounds the nerve roots in the lower back. The procedure is usually performed on an outpatient basis, and most patients experience relief from back pain within a few days. The sacral injection is another name for a caudal epidural injection. It is a type of spinal epidural injection that is administered to the sacral hiatus, which is the opening at the base of the spine near the tailbone. The injection is used to treat nerve pain and inflammation caused by conditions such as spinal canal stenosis, herniated disks, degenerative disk disease, sciatica, or radiculopathy.

DADA2 (deficiency of adenosine deaminase type 2) is an autoinflammatory autosomal recessive disease resulting from biallelic loss of function mutations in ADA2 gene. Clinical presentation and age of onset vary widely even among related patients, and variability of symptoms and severity manifestations include bone marrow failure, autoinflammation, immunodeficiency and vasculitis. Here, we report a case of young male with adult onset DADA2, who presented with fever, lower limbs skin rash, joint pain, and anemia resembling systemic lupus erythematous (SLE). DADA2 has an extremely variable clinical phenotype. It was described into three categories: inflammatory/vascular, immune dysregulation, and hematologic. However, the data is scant in describing autoimmunity phenotype in DADA2 and further studies are required to investigate the clinical correlation and presence of autoantibodies. We recommend genetic testing in cases with lupus-like disease especially if there is consanguinity between parents and family history of vasculitis.

Syphilis is caused by the bacterium Treponema pallidum and is transmitted from human to human through sexual contact. Congenital syphilis (CS) occurs when the mother transmits the infection to the fetus. Clinical manifestations of CS include anemia, hepatosplenomegaly, blindness, deafness, meningitis, and deformities in bone structure. The number of cases of CS have increased over the past decade in the United States according to the CDC. A study was conducted correlating the number of Medicaid enrollees in 2020, the number of uninsured persons in 2020, and the number of cases of COVID-19 in 2020 to cases of CS in the United States in 2021. A Spearman rank correlation analysis was done using SPSS. Results were statistically significant for all three pairs of variables with positive correlations; Medicaid enrollment and CS cases (r = 0.735, P<.05), uninsured persons with CS cases (r = 0.713, P<.05), COVID-19 cases and CS cases (r = 0.689, P<.05). Reasons for the increase in CS cases are multifactorial, including variations in state laws regarding syphilis screening in the prenatal period, differences in provider processes for persons on Medicaid, persons uninsured, and restrictions to accessing healthcare providers during the COVID-19 pandemic. Future studies should include questionnaires and interviews with women on their experiences during prenatal visits in regards to syphilis screening, particularly women covered by Medicaid, and surveys completed by healthcare providers to gain insight and to identify factors that affect a woman not being tested for syphilis during her pregnancy.

The increasing demand for environmentally-friendly materials has led to a surge in research on the production of biodegradable polymers. In this study, we investigate the synthesis of a biodegradable polymer by graft copolymerization of gum Arabic (GA) and polyethylene glycol (PEG). GA, a natural polysaccharide and PEG, a synthetic water-soluble polymer, were used as the backbone and graft monomer, respectively. The graft copolymerization was carried out using benzoyl peroxide as an initiator and performed under nitrogen atmosphere. The resulting polymer was characterized by Fourier transform infrared (FTIR) spectroscopy, Xray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the graft copolymer, and TGA analysis showed that the copolymer had higher thermal stability than GA. The DTA thermograms indicated two thermal events. The evaporation of water and organic polyethylene glycol components was measured, and the first mass loss was due to the loss of adsorbed and structural water in the gum Arabic, which occurred between 31.87 and 180°C, while the second, corresponding to the pyrolysis of polyethylene glycol functional groups and polysaccharide decomposition, resulted in a 70% mass loss. SEM morphological analysis of gum Arabic showed aggregates of high irregularity in particle shape. The cracks and holes obtained in the Gum Arabic micrograph disappeared from the new gum Arabic-graft-polyethylene glycol, leaving a smooth surface with scattered particles in the image, which was due to the grafting copolymer. From the XRD patterns, the percentages of the amorphous and crystalline phases were determined. The results show that gum Arabic has a 78% degree of crystallinity, whereas gum Arabic-graft-polyethylene glycol has the lowest value of 51%. Biodegradation activity was observed using the fungus Aspergillus flavus on different days on gum Arabic-g-polyethylene glycol. The results clearly showed inhibition zones with a change in the state of the copolymer from solid to liquid from days 8 to 14. These results indicate that the GA-PEG copolymer has potential as a biodegradable material for use in various applications, such as packaging, agriculture, and medical industries.

Background Monoclonal gammopathy of undetermined significance (MGUS) and chronic myeloid leukemia (CML) are diseases of different lineages. The diagnosis of both MGUS and CML in the same patient is a rare occurrence and has not been reported in much literature. Case Presentation We describe a 56-year-old man with a history of rheumatoid arthritis incidentally found to have an increase in IgA paraprotein. With less than 10% monoclonal plasma cells on the bone marrow biopsy and absence of hypercalcemia, renal failure, anemia and bone lesions, MGUS was diagnosed. The conventional cytogenetics at the time showed the presence of the Philadelphia chromosome in 30% of metaphases. However, there was no morphologic evidence of CML in the peripheral blood or bone marrow. Patient received no treatment and lost follow-up until 3 years later when a routine CBC showed leukocytosis and thrombocytosis. CML, chronic phase was diagnosed following a bone marrow aspiration and biopsy with Philadelphia chromosome observed in 100% of metaphases. Patient was treated with imatinib and later switched to dasatinib and complete molecular remission was continued to be achieved. Discussion and Conclusion Here we report a case of pre-leukemic CML as an incidental finding during the diagnosis of MGUS. The possible underlying mechanisms of the association are discussed although the exact cause of the coexistence is unclear.

Aim There is limited published data describing the characteristics of the paediatric population prescribed semi elemental formulas. This retrospective observational audit aimed to describe the characteristics of the paediatric patients who have been prescribed a hydrolysed whey protein, medium chain triglycerides (MCT) based formula, Peptamen Junior® and the nutritional outcomes. Methods A retrospective observation audit was completed on a cohort of patients that was prescribed a semi elemental formula between 2016 and 2019 from a single tertiary paediatric medical centre. Data variables were collated such as patient characteristics, indications and modalities of administration, duration and tolerance to the formula. Results Data was collated on 375 patients with a median age of 6.2 years. The main underlying medical conditions were haematological/oncology (67%), gastrointestinal disorders (10.7%) and neurological conditions (9.4%). The most common indications for use were chemotherapy related side effects (36.2%), post bone marrow transplant (25.8%) and gastrointestinal symptoms (17.9%). The formula was rarely used as a sole source of nutrition, with 88% patients requiring accompanying forms of nutrition support. The majority of orders prescribed were of standard concentration (80.8%) and tolerance was recorded in 82.8% of patients. Conclusion The semi elemental formula Peptamen Junior® appears to be well tolerated in paediatric patients with a variety of medical conditions that have complex pathologies and may have wider scope of use in a more diverse group of medical conditions than currently indicated.

Background Human malignant cell models which reflect the structural and physiological complexity of tumor tissue are of great importance for preclinical research in oncology. Spheroids/tumoroids derived from solid tumors are of great interest as cellular models mimicking the first vascular-free growth phase of a tumor node. The fact of the identity between artificially created tumor multicellular aggregates and the real tumor tissue, however, needs to be specified, described and validated in order to see how closely the spheroids are biologically similar to the malignized tissues in vivo compared to the monolayer cell cultures traditionally used. We present here a comparison study of the characteristics of solid tumor cells of different histogenesis (melanomas, soft tissue sarcomas and bone sarcomas, epithelial tumors) cultured in two dimensions (monolayer culture) and three dimensional space (spheroid), namely: spatial organization, multiplication, metabolic activity. Patients and Methods For the creation of 2 D and 3D cell models the cells isolated from the patient's solid tumor fragments obtained intraoperatively were used. 15 samples of skin melanoma, 20 samples of soft tissue and osteogenic sarcomas (STBS), and 9 samples of epithelial tumors (ET). The tumor cells were all cultivated for at least 10 passages. We used phase contrast, confocal microscopy, and immunohistochemistry to investigate spheroids and monolayer cultures. The supernatants of tumor cells grown in 2D and 3D cultures were studied using ELISA and multiplex analysis for the production of a spectrum of chemokines and cytokines supporting the immunosuppression, invasion and metastasis processes. Results Tumor specimens received were predominantly of metastatic origin (75%). In 100% of cases 2D cultures were received, in 88.6% of cases (39 out of 44) we succeeded in obtaining spheroids. There was no direct correlation between the efficiency of tumoroid formation and the tumor's histogenetic origin and the stage of the cancer process (primary tumor, recurrence, metastasis). The median size of spheroids by 4-5 days of cultivation with a starting concentration of 10000 cells per well was 657.14 μm for melanoma (min 400 - max 1000 μm), 571.42 μm (min 400 - max 700 μm), 507.14 μm (min 300 - max 600 μm) for soft tissue sarcomas, 650.0 μm (min 400 - max 900 μm) for osteogenic sarcomas. Immunochemical analysis of Ki-67, GLUT1, and Ecadherin markers was carried out for tumor tissue samples, single-layer tumor cultures, and tumoroids of every patient. The distribution of the stained groups in the spheroids was distinct from the monolayer cultures and more in accordance with the distribution of such in the tissue tumor, the number of Ki-67+ cells was increasing in the spheroids. We detected no dependence of Ki-67+ and GLUT1+ cell localization grade on spheroid size. We identified E-cadherin in tumor tissue and tumoroids of breast carcinoma and one melanoma culture. Monolayer cultures did not express it. The increase in secretory cell activity of the solid tumor cells from 2D to 3D system was observed when CCL2, CCL3, CXCL1, CXCL16, MIF, IL10, MICA (p<0.01) were investigated. Conclusion The presence of patient-specific cells of solid tumors in a 3D environment causes activation of the proliferative and metabolic processes as compared to monolayer cultures, which makes these models approximate the real world clinical picture. The production of chemokines that can attract to the tumor various types of immune system cells, to include their immature versions, as well as production of cytokines and Immunosuppression factors that, when present in the tumor microenvironment in the high concentrations, contribute to the formation of immune cells having suppressive capacities occurs in the 3D cell system. Three-dimensional model of the initial tumor nodule formation stage thus demonstrates the forming process of tumor cells favorable for them microenvironment. Construction of three-dimensional models - spheroids of tumor cells of differing histogenesis demands individual approach and more thorough investigation.

During routine dissection of the right hand of a 52-year-old Asian descent male cadaver in the Department of Anatomy at Jazan University-Faculty of Medicine, we observed an anatomical variation of the ulnar nerve (UN). There was a trifurcation of the nerve in the ulnar tunnel proximal to the pisiform bone. An awareness of such variation may be of great clinical importance despite the presence of trifurcation of the ulnar nerve, which does not usually cause symptoms but becomes important in the evaluation of entrapment neuropathy and during surgical and orthopedic interventions

We report 2 cases of vitamin B12 deficiency in children due to deficient intake. These were 2 girls aged 4 years (case 1) and 6 years (case 2), respectively, hospitalized in December 2020 and March 2021 in the pediatric ward of Le Dantec hospital. Both patients presented with aregenative anemia, melanoderma and undernutrition. The bone marrow count in case 1 showed a dysmyelopoiesis with megablastosis. The blood vitamin B12 level was low in both cases. Folic acid blood levels were normal in both patients, but an associated martial deficiency was found in case 2. The dietary survey revealed a lack of intake of animal products rich in vitamin B12. Vitamin B12 replacement therapy was effective with rapid regression of all clinical signs observed in both children. The control of the vitamin B12 level after 1 month of treatment was normal in both patients. The disappearance of the symptoms under substitute treatment confirmed the deficiency of Vitamin B12 intake in both patients. Conclusion: Both of our patients had a profound Vitamin B12 deficiency in a context of deficiency in nutrition. The regression of the symptoms was spectacular under vitamin B12 replacement therapy, confirming the deficiency. We recommend in our context a contribution in micronutrients such as vitamins in children after weaning to avoid dietary errors.

Auto transplantation is a fast and economical option when a suitable donor tooth is available for replacement of a tooth considered impossible to treat. The purpose of this case report is to describe methods used for autotransplantation and its advantages for cases with a missing bilateral mandibular firstmolar, as compared with a dental implant, removable partial denture, and other methods of prosthesis. In the present patient who underwent auto transplantation, clinical and radiographic outcomes were considered satisfactory at one and two years postoperatively. Bone healing was observed around the roots of transplanted teeth, which showed good function. In autotransplantation cases, even when the donor tooth has complete root formation, a high success rate can be achieved when the patient is properly selected and treated. Although the chance of root resorption remains because of necrotic pulp and periodontal irritation during manipulation, auto transplantation should be considered as a good treatment modality in feasible cases. Based on the present findings, even though autotransplantation is not common in general dental practice, we consider that it offers a clinically and economically viable alternative as compared to other more complicated prosthetic and dental implant treatments. The purpose of this report is to show that auto transplantation is a superior treatment method for single molar defects as compared to other prosthetic methods, as the periodontal ligament of the patient can be used and cutting adjacent teeth is avoided. In addition, it is a treatment method that can effectively utilize a wisdom tooth.

Introduction Large impaled object in the orbital region causes severe visual impact and requires specialized care within the shortest time possible. Objectives In this case report, we discussed the approach and management of a patient that presented with a penetrating orbitocranial injury, from management at the emergency unit, diagnostic imaging, referral to other subspecialty, surgical and medical intervention, and post-operative care. Discussion A 36-year old male had an impaled toilet brush on the supero-nasal aspect of the right orbit, with visual acuity of 6/60 and lacerated upper eyelid. The globe had minimal movement on all gazes, but pupil was reactive to light with no afferent defect. On plain cranial and orbital CT-scan, the foreign body entered the anterior and medial aspects of the right orbit penetrating the right superior orbital wall, right medial lamina papyracea, and the lateral and inferior border of the right frontal sinus with its distal tip at the intracranial region at the right frontal lobe compressing the medial rectus along its tract. Two hours after injury, patient underwent wound exploration, removal of foreign body, repair of eyelid laceration, right craniotomy, frontal contussectomy, duraplasty, and JP-drain insertion under general anesthesia. Intraoperatively, there was note of transected canaliculus and avulsed conjunctiva. The medial rectus was intact and attached. The frontal lobe was contused with embedded fragments of right posterior orbital bone with 3cm opening on the dura. Post-operatively, Fluconazole was added to the medications after culture results of the toilet brush tip tested positive for fungal elements. Patient was discharged after 21 days with visual acuity of 6/6 on both eyes and improved ocular movement. Conclusion These types of injury warrants thorough and systematic history taking and physical examination, acquiring pertinent imaging modalities to better visualize the extent of injury, and execute surgical and medical intervention that is multidisciplinary.

Introduction The extra dural hematoma is a blood collection between the cranial vault and the dura mater. It is a neurosurgical emergency whose statistical data are poorly known in the Republic of Benin. Objective The aims of this study are to assess epidemiology, therapeutic and outcome of traumatic extra dural hematomas for children admitted to the surgical department of CHUD-B/A from 2012 to 2017. Methods This was a cross-sectional, descriptive and retrospective study over a period from January 1st, 2012 to December 31st, 2017. Results One hundred and seventy-eight cases of children aged between 0-15 years were examined for brain traumatic injury. Twenty-seven 27 (15.2%) cases of extra dural hematomas were retained. The most represented age group was between 11-15 years with a frequency of 42.1%. The male sex was more represented (78.9%). Road traffic accidents were the main aetiology (57.9%). 52.6% had a mild head injury, 26.3% had a moderate head injury and 21.1% had a severe head injury. On brain scan the frequently observed location was temporo-parietal (31.6%). Acute anemia was observed in 16 children. Seventeen children were operated on. The operation involved evacuation of extra dural hematoma by cranial bone flap with suspension of the dura mater. There were no deaths. Conclusion The availability of brain CT makes the diagnosis of extra dural hematoma easier. Its management is neurosurgical with a favourable post-operative evolution in all cases in this series.

Plasma cell neoplasms of the thyroid gland are uncommon. They may occur either as a primary extraosseous (extramedullary) plasmacytoma or as secondary involvement by multiple myeloma (MM). Here, we report the case of a 62-year-old female, presenting with goiter and Hashimoto’s thyroiditis, in whom the histologic diagnosis of extraosseous plasmacytoma was unexpected. Histology of the total thyroidectomy specimen showed a diffuse infiltration of well-differentiated plasma cells against a background of Hashimoto’s thyroiditis. By immunohistochemistry, the majority of the plasma cells are positive for IgG heavy chain and kappa light chain (kappa:lambda ratio was about 6-7:1). PCR analysis of the immunoglobulin heavy and kappa chain (IGH, IGK) gene rearrangements showed clonal IGH and IGK gene rearrangements. MM was ruled out by lack of MM-related end organ damage and negative serum protein electrophoresis, immunofixation, and bone marrow biopsy. Although rare, plasmacytoma should be considered in patients presenting with enlarging thyroid gland and autoimmune thyroiditis. Histologic diagnosis and differential diagnoses are comprehensively discussed.

The cactus Opuntia ficus indica (L.) Mill. (Cactaceae) is widely used in Tunisian medicine for the treatment of various illnesses. The purpose of the present study was to investigate the antioxidant activities of cactus cladode extract (CCE) and to assess the protective effects of Opuntia ficus indica against osteoporosis induced by cadmium chloride in male Wistar rats. Adult male rats were divided into 4 groups of 9 each: a control group, a group injected with cadmium (3.5mg/kg) for 10 weeks, a group orally given a O. ficus indica cladodes aqueous extract (CCE) (100 mg /kg/day) for 10 weeks then treated with cadmium, and a group receiving only (CCE) for 10 weeks. Bone toxicity was estimated by examining femoral length and weight, calcium, phosphorus, alkaline phosphatase (ALP) and total tartrate-resistant acid phosphatase (ACP) levels in serum. Also, bone levels of calcium, phosphorus and vitamin C and bone mineral density (BMD) of femur diaphysis were measured. Alterations of these bone biomarkers and decreased BMD confirmed cadmium-induced bone toxicity. However, when cadmium was administered in rats given CCE, all the biological parameters underwent much less alteration. Administration of CCE was found to be beneficial by attenuating cadmium-induced femur damage. The protective effect of the plant is mainly attributed to its phenolic compounds that orchestrate antioxidant properties, as highlighted by HPLC-based analysis.

Immune thrombocytopenia currently called under its’ new name, immune thrombocytopenic purpura (ITP) is a disease characterized by thrombocytopenia, in which the body attacks its own platelets due to the disorders in immune system. The pathophysiology of this disease includes increased platelet destruction and most megakaryocyte production in bone marrow. The most common clinical manifestation of ITP is mild or severe progressive bleeding that could result in death. ITP is generally named as primary or secondary ITP according to thrombocytopenia severity, disease duration, bleeding status and secondary occurrence of the disease. Currently for diagnosis, despite the blood count, antiglobulin test and laboratory tests that can detect platelet-bound antibodies, they are not enough for definitive diagnosis. Like the difficulty in diagnosis, ITP treatment is quite complicated which varies depending on age, characteristics and risk of the patient. It is classified as first, second and third-line treatment options. Also, depending on the condition of patients, combined treatment might be an option which increases the complexity of the treatment. Unfortunately, discussions related to different clinical applications in diagnosis and treatments continue recently. For this reason, we considered that preparation of a review containing recent updates in diagnostic approaches and treatment options in ITP will be remarkable and beneficial for physicians interested in this subject.

Aim of the Research The aim of this study is to analyze a group of dogs of different breeds affected by osteosarcoma (OSA), to document any prevalence of this primary bone neoplasia in breeds that are phylogenetically close and to help with further research human medicine, as a model of study for prevalence and epidemiology of human OSA in multiple populations. Study Design Pilot study from two canine surgery databases between 2002 and 2013. Materials and Methods Breeds were classified in groups based on their phylogenetical proximity. Differences in prevalence of OSA between breeds and groups were evaluated with a permutation test. For each breed and each group, a ranking was made by calculating 95 % confidence intervals and counting the no-overlapping between breeds and groups. The relation between the dogs’ heights and the prevalence of OSA was analyzed using a logistic regression between the disease status and dog size. Results A total of 67 dogs with OSA, in 26 different breeds were included. Ten breeds were overrepresented and, the majority of these, were classified in 2 predisposed groups phylogenetically close to each other. The prevalence of OSA was associated with the dogs’ height within predisposed breeds, but, in general, taller breeds were not the most affected. Conclusions and Clinical Relevance In this study, despite the small number of dogs, we observed that the most commonly affected breeds with OSA are phylogenetically closely related. This highlights the importance of genetics in the aetiology of canine OSA . In this preliminary study, indications are given on breeds, samples and genome locations to be further investigated. This could allow identification of pathogenic alleles in dogs, and potentially in humans. Furthermore this pilot research can represent a model of epidemiologic study of human OSA.

Waldenström Macroglobulinemia (WM) is a B-cell lymphoproliferative disorder characterized mainly by uncontrolled accrual of M- immunoglobulin, secreted by malignant lymphoplasmatic cells. Mast cells interacting with malignant B-cells play an important role at the manifestation of the disease. Utilizing a previous xenotransplantation mouse model, this study evaluates long-term implant viability and quantifies distinct bone marrow mast cell populations along with their dynamics in non-WM and WM human bone implants. Non-WM bone implants were obtained from the femoral head of adult humans undergoing hip arthroplasty or hemiarthroplasty, whereas WM human bone implants originated from bone biopsies obtained from the posterior iliac crest of patients with active WM. All bone particles were implanted intramuscularly in twenty-four NOD/SCID mice. Following 3, 4 or 8 months postoperatively, xenografts were removed and studied using special histological techniques to identify mature and immature mast cells. Xenografts survived up to 8 months after implantation presenting normal cytoarchitecture (non-WM) or high-grade neoplastic infiltration and microresorption (WM bone biopsies). Statistical analysis of mast cell populations showed significant elevation regarding time progression and bone marrow microenvironment, thus suggesting the possible influence of malignant cells to the mast cell population in WM. This study presents the extended survival of intramuscular implantation of human adult bone xenografts into NOD/SCID mice and provides additional information on the interaction between mast cells and malignant B-cells.

Introduction The human tibia is a complex anatomical unit and the knowledge of its morphometric values is important in Forensic, Anatomic and Radiological cases in order to identify unknown bodies and stature. Objective It was to analyze the tibia, its morphometry, side difference and to investigate the position of nutrient foramina in tibia. Methods In this study, 60 adult human tibias (30 right and 30 left) were obtained from the Department of Anatomy SMSR SHARDA UNIVERSITY. In the study a total of two parameters i.e. Cross Section Index in the middle and Cnemicus Index of the bones were obtained and evaluated by using two instruments- a Measuring Tape and a Vernier Calipers. All the bones were dry and showed normal anatomical features. Results The mean Cross Section Index in the middle was calculated as 80.42 ± 11.33 on the right side and 78.15± 12.78 on the left side; and the Cnemicus index was 78.40 ± 13.19 on the right side and 70.84 ± 11.38 on the left side Conclusion The two parameters in the North Indian population were compared with other populations. The values were found to be almost comparable however there were subtle differences between different populations. The position of nutrient foramen was also assessed. This knowledge will thus help further researchers and orthopedic surgeons in various procedures like joint replacement therapy, fracture repair, bone grafts and vascularized bone microsurgery as well as in medico‐legal cases.

Radial Club Hand (RCH) is a rare and complex congenital disorder of the pre-axial border of the upper extremity. It is a congenital longitudinal radial ray deficiency which presents as radial deviation of the hand and distal forearm in the shape of a golf club 12. Radial ray deficiency (the most common type of longitudinal failure of formation) is a spectrum of malformations affecting the structures of the radial side of the forearm, including hypoplasia of the bones, joints, muscles, tendons, ligaments, nerves and blood vessels. The thumb dysfunction, wrist instability and short upper extremity that accompany this condition can cause significant functional impairment particularly in patients with bilateral involvement. Thus, the performance of activities of daily living such as accomplishing personal hygiene, fastening buttons and zippers becomes challenging 3.

Purpose To report a rare case of Inverting Papilloma originating from the Lacrimal Sac in Tertiary Hospital. Method Case report. Results Inverting papilloma is uncommon in lacrimal sac. More often presents in Maxillary sinus, Ethmoid sinus and lateral wall of nasal cavity. This case of 69 years old, Filipino male, who presented with a two-year history of gradually enlarging left medial canthal mass, and tearing. There were no ophthalmoplegia, visual disturbances, proptosis or pain but there was globe displacement superolaterally. Other ophthalmologic examinations were unremarkable at that time of examination. Orbital CT-scan revealed: Heterogenously enhancing mass extending to ipsilateral nasolacrimal canal and nasal cavity causing mass effect. There was note of a suspicious area of hyperostosis. Patient was referred to the Department of Otolaryngology Head and Neck Surgery for co-management. Punch biopsy was done and histopathology revealed Inverting papilloma. Combined surgical management of anterior Maxillectomy via lateral Rhinotomy approach and Dacryocystectomy was done. Intraoperatively, there was note of adhesions to bone in the area of the Lacrimal Sac corresponding to the area of hyperostosis on CT-scan. Post-operative recovery was unremarkable with unchanged visual acuity and extraocular muscle movement. Conclusions This is a case of an inverting papilloma involving the lacrimal sac and nasolacrimal duct that was managed with combined anterior maxillectomy via Lateral Rhinotomy approach and dacryocystectomy for complete resection. We recommended complete resection of the tumor to minimize recurrence. Origin in the Lacrimal Sac area was confirmed by intraoperative findings which correlated with CT- scan findings.

Breast cancer has high incidence in women from both developed and developing countries. Approximately 2 million women are diagnosed with breast cancer in 2018. In Asia, unfortunately Pakistan leads the highest number of breast cancer patients. Various treatment strategies are present but they are not well developed. There is a great need to develop effective methods for early detection and treatment of the disease. For cancer treatment chemotherapeutic interventions have always been a method of choice. One of the mechanisms involved in cancerous cell proliferation is Mevalonate (MVA) pathway. It is hypothesized that arresting MVA pathway leads to cell death hence cancer cell growth is suppressed. Various inhibitors of MVA pathway have been studied that can suppress cell proliferation. Nitrogen containing bisphosphonates are MVA pathway inhibitor and clinically used for treatment of bone diseases. Their anticancer efficacy is also reported. Current study focuses on alendronate, a nitrogen containing bisphosphonate to examine their anticancer effect on breast cancer cell line. Results of this study may help in addition of new anticancer drug for breast cancer.

Multiple organ dysfunction syndrome or failure is one of the major concerns against healthcare services in order to maintain the normal function. The present study aimed to explore the impact of the Biofield Energy Treated test formulation on the function of vital organs such as bones, heart, liver, lungs, and brain using standard activity parameters in specific cell-based assays. The test formulation and cells medium was divided into two parts, one untreated (UT) and other part received the Biofield Energy Treatment remotely by a renowned Biofield Energy Healer, Ariadne Esmene Afaganis, Canada and was labeled as the Biofield Treated (BT) test formulation/media. The test formulation was tested for cell viability, and the data suggested that the test formulation was found safe and non-toxic against all the cell lines. Cytoprotective activity among the experimental groups showed a significant improved activity by 94.4% at 1 µg/mL in untreated medium (UT-Med) + Biofield Treated Test Item (BT-TI) group in human cardiac fibroblasts cells (HCF) cells, while 84.4% at 10 µg/mL in BT-Med + BT-TI groups in human hepatoma cells (HepG2), and 124% increased cytoprotective action at 1 µg/mL in UT-Med + BT-TI group in adenocarcinomic human alveolar basal epithelial cells (A549) cells as compared with the untreated test group. ALP activity in MG-63 cells was significantly increased by 85.9% at 10 µg/mL in the UT-Med + BT-TI group, while in Ishikawa cells showed maximum increased ALP activity by 59.2% at 0.1 µg/mL in BT-Med + BT-TI groups as compared to the untreated group. The percent protection of HCF (heart) cells (decreased of LDH activity) was significantly increased by 53% and 40.5% at 1 and 10 µg/mL concentrations respectively, in UT-Med + BT-TI group, while BT-Med + UT-TI group showed increased protection by 68.5%, 70.7%, and 16.8% at 0.1, 1, and 10 µg/mL respectively, and 86.5%, 62.5%, and 34.2% improved cellular protection at 0.1, 1, and 10 µg/mL respectively, in BT-Med + BT-TI group as compared to the untreated test group. The percent protection of HepG2 (liver) cells (decreased of ALT activity) was reported by 33.5%, 63.2%, and 99.2% at 10 µg/mL in the UT-Med + BT-TI, BT-Med + UT-TI, and BT-Med + BT-TI groups, respectively compared to the untreated group. Cellular protection of A549 (lungs) cells (increased of SOD activity) in terms of percentage was increased by increased by 39.8% (at 10 µg/mL), 44% (at 25.5 µg/mL), and 59.7% (at 25.5 µg/mL) in the UT-Med + BT-TI, BT-Med + UT-TI, and BT-Med + BT-TI groups, respectively compared to untreated group. Serotonin level was significantly increased by 59.2% (at 0.1 µg/mL), 190.3% (at 0.1 µg/mL), and 201% (at 1 µg/mL) in the UT-Med + BT-TI, BT-Med + UT-TI, and BT-Med + BT-TI groups, respectively compared to untreated in human neuroblastoma cells (SH-SY5Y). However, the relative quantification (RQ) of vitamin D receptor (VDR) was significantly increased by 159.1% (at 50 µg/mL), 212.7% (at 1 µg/mL), and 278.3% (at 10 µg/mL) in the UT-Med + BT-TI, BT-Med + UT-TI, and BT-Med + BT-TI groups, respectively as compared to the untreated in MG-63 cells. Thus, the present data concluded that the overall multiple organ health using various standard biomarkers in specific cell lines were significantly improved with respect to health of bones, heart, liver, lungs, and brain after treatment with the Biofield Energy treated test formulation (The Trivedi Effect®). Thus, it can be used as a complementary and alternative therapy approach against many multiple organ disorders such as coronary artery disease, arrhythmias, congenital heart disease, cardiomyopathy, cirrhosis, liver cancer, hemochromatosis, asthma, chronic bronchitis, cystic fibrosis, osteoporosis, etc.

Dental implant restoration is challenging procedure when it involve the esthetics zone, and since implant dentistry is prosthodontically driven procedure, care were practice in restoration of missing teeth in esthetics area which will fulfill the objective. Extraction of teeth leave buccal plate bone unsupported and decrease the blood supply and since this plate is very thin resorption will be expected. Different attempt was done in order to prevent this sequence and create natural emergence profile around dental implant prosthesis. Socket preservation procedures were introduced, however in case of ridge deficiencies, hard and soft tissue augmentation procedures are indicated. Socket shield technique meets the demands of minimal invasion, tissue preservation, and no need of bone substitute materials. And can be applied not only for maintaining buccal contour of an edentulous ridge but also for keeping the inter-implant soft and hard tissue In this review paper we present different articles and case report using socket shield technique as treatment protocols and try to explore different protocol are practice in order to achieve high treatment out come with optimal success.

Vitamin D, the sunshine vitamin, is now recognized not only for its importance in promoting bone health in children and adults, but also for its other health benefits, including reducing the risk of chronic diseases such as autoimmune diseases, common cancer, and cardiovascular diseases. Ultraviolet radiation of the sun with wavelengths of 290-310 nm penetrates into the skin and converts 7-dehydrocholesterol to previtamin D3, which quickly transforms to vitamin D3. Vitamin D (D represents either D2 or D3) made in the skin or ingested through diet is biologically inert and requires two successive hydroxylations first in the liver on carbon 25 to form 25-hydroxyvitamin D 25(OH)D and then in the kidney for a hydroxylation on carbon 1 to form the biologically active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D) 121419. The concentration of the produced 25-hydroxy vitamin D in blood circulation is 1,000 times more than 1,25-dihydroxy vitamin D 4, and it is regarded as a standard indicator of vitamin D status in humans 3. 25-hydroxy vitamin D half-life is about 2-3 weeks and it is regulated by calcium (Ca), phosphorus (P), and serum parathyroid hormone (PTH) to some extent. 25-hydroxy vitamin D content also reflects the amount of vitamin D produced in the skin after exposure to sunlight or received through food intake 56. Guidelines for vitamin D insufficiency/deficiency defined by serum 25(OH)D concentrations have been published from many countries and regions all over the world 7891011. Vitamin D deficiency is a pandemic problem. According to global estimations, more than one billion people around the world suffer from vitamin D deficiency. Among Iranian population, the incidence of vitamin D deficiency varies from 2.5 to 98.5% based on geographic area 1213. Various factors may give rise to vitamin D deficiency, including skin pigments, low levels of vitamin D in diet (insufficient fish oil and egg yolk intake), malnutrition, genetic factors, exclusive breast feeding, vitamin D deficiency of mother during pregnancy, prematurity, chronic use of drugs (e.g., anticonvulsants, aluminum-containing anti-acids, rifampcin, isoniazid, antifungal drugs, antiviral drugs, and glucocorticoids), winter and obesity 113. Cultural habits, the need for full body coverage during outdoor activities and the lack of sunlight programs are the risk factors for low vitamin D levels in women 151617. Children enter foster care due to early childhood adverse experiences such as poor prenatal and infant health care, food insecurity, chronic stress, and the effects of abuse and neglect. As a result, they are at higher risk for poor physical, psychological, neuroendocrine and neurocognitive outcomes compared to others. Foster children are at risk for growth and nutritional deficiencies due to their poor nutritional environment prior to placement in foster care. Insufficient caloric intake results in growth deficiencies. Evidence showed that the risk of stunting and underweight is high in this population 18. The risk of developing hypovitaminosis D was significantly higher in children living in foster homes. One reason is that they are at higher risk of child abuse, emotional deprivation and physical neglect than children living with their families. Moreover, these children most likely do not spend much time outdoors and they lack adequate sun exposure. Another reason is that as children grow up in institutional care, they shift from a diet of vitamin D–fortified formula milk to cooked food, which may not be fortified with vitamin D 1. Iranian government has made some efforts to apply efficient interventions to reduce the prevalence of vitamin D deficiency, and the country’s healthcare system should be managed through accurate planning. Yet, in this country, studies on vitamin D deficiency in children living in foster homes are very limited, and given that timely diagnosis and treatment of this deficiency is vital, this research is conducted in Ali Asghar foster home in Mashhad, Iran.

In the last few years, gut microbiota has been identified to be an essential mediator in health and disease. In fact, it interacts with various organs and systems in the body, including brain, lung, liver, bone, cardiovascular system, and others. Microbiota-derived metabolites such as the short chain fatty acid (SCFA) butyrate are primary signals, which link the gut microbiota and physiology. Then, the findings on the roles of microbiota profoundly change not only the key concepts of biology and medicine, but also of nutrition. In fact, it is currently evident how the main task of nutrition is not to nourish us, but to maintain a comfortable environment for the intestinal microbiota. In this way, it works in symbiosis with us, correctly controlling the functioning of the organs, the physiological parameters and the cellular regenerative processes. It is also evident that the strength of reparative processes correlates with the ability of digestive system to process complex foods, which increases during weaning, a period of time in which the diversity of bacterial strains increases. Therefore, a task of food is to keep trained the digestive system, to which it corresponds an high microbiota diversity. Elderly leads to reduced microbiota diversity to which corresponds an intestinal frailty, responsible for the frailty of the elderly. In conclusion, a correct diet may not only keep us in good health but may also guarantee us longer longevity.

Theobjective of reviewing Hairy Cell Leukaemia may be achieved by emphasising the condition as a category of chronic lymphocytic leukaemia with hair like protrusions of the cytoplasm situated on the aberrant B cell surface. An infrequent disorder, hairy cell leukaemia contributes an estimated 2% of lymphoid malignancies with a male predominance ( M:F ::4-5:1). A majority (90%) of instances depict a mutant immunoglobulin heavy chain variable region (IGHV). The haematopoietic stem cells (HSCs) elucidate a B raf proto-oncogene( BRAF V600E gene- 7q34). An enlarged spleen may be discerned along with pancytopenia as a presenting symptom. The morphology of specific hairy cell leukaemia may be on account of an in vitro interaction of primary hairy cells with BRAF genes and MEK inhibitors, which incite a prominent MEK - ERK dephosphorylation, thereby curtailing transcriptional outpourings of the RAS- RAF- MEK-ERK pathway. Bone marrow aspiration or bone marrow trephine biopsy may be inadequate for diagnosis in 30%-50% individuals on account of extensive fibrosis and the bone marrow sections depict a characteristic interstitial infiltration of leukaemia cells.. Reticulin stains exhibit broad, dense reticulum fibres surrounding the individual or aggregates of leukaemia cells with fibrotic extensions into the abutting bone marrow. The immune reactivity of classic hairy cell leukaemia is concurrent CD19+ CD20+,CD 11c+, CD25+, CD103+ and CD123+. Immune staining for CD20+, annexin 1 and VE1 (a BRAF V600E stain) validates the diagnosis and analyses the extent of malignant bone marrow infiltration. Application of inhibitors of BRAF V600E gene is efficacious in patients resistant to standard therapy. An enlarged spleen beyond 3 centimetres of the left costal margin, a white blood cell count greater than 10000 cells/µL , circulating hairy cells in the peripheral blood greater than 5000 cells/µL and a β 2 micro-globulin level exceeding twice the normal range of 3 µg/ml delineate an inferior outcome with resistance to purine analogues (PNAs). CD38+ elucidation ensures a worse prognosis as does the lack of an IGHV mutation with a reduced overall survival,. A lack of BRAF genetic mutation in 10% -20% of hairy cell leukaemia comprises of inferior prognosis.

MicroRNAs are short sequences of non-coding RNAs crucial in regulation of cell development, proliferation and differentiation. Some of them showed to be related with the expression of osteogenic genes. Aim of the present review was to evaluate the biological effects of titanium implant surfaces activated with miRNAs or antimiRNAs. A bibliographical electronic research was carried out on PubMed/Medline. Articles investigating the influences of miRNA functionalized surfaces on human or animal cells were included. Reports were excluded if investigating surfaces modified with molecules different from miRNAs, if miRNAs were not loaded to titanium surfaces. Five articles met the inclusion criteria. Surfaces functionalized with miRNAs showed to up-regulate the expression of osteogenic genes like RUNX2, OPN, OCN, BMP, OSX, ALP, COL1 and COL3. Investigated surfaces additionally showed more bone-like mineralized tissues, bone lacunae, osteocytes and new blood vessels. MiRNAs loaded to titanium implant surfaces stimulate the expression of genes related to osteoblasts differentiation, osteogenesis, osseointegration and reparation of mineralized tissues. Vectors used to link titanium surfaces and miRNAs did not show cytotoxicity or interference with cells’ viability.

A rare case of association between primary sclerosing cholangitis and Paget's disease emphasizing the diagnostic difficulties in front of increased alkaline phosphatase is reported. The association between sclerosing cholangitis and Paget's disease wasn’t yet described and could thus be coincidental. However, our observation underlines the benefit of dosing ALP isoenzyme to characterize the bone or hepatic origin of ALP and therefore, help to guide the diagnosis.

The role that Vitamin D plays in human health is no more hidden in this modern age where every individual carries the knowledge treasure in the pocket (The internet) but the unjustified deficiency or insufficiency is still a research question waiting for the answer from research community all over the world. Normal levels (30-50 ng/ml) are necessary for the development of teeth and bones in children and bone mineralization in adults. The deficiency or insufficiency causes rickets, arthralgia, arthritis, osteoporosis and Osteomalacia. Study Design: Observational study. Study Setting: Department of Orthopedic LUMHS Jamshoro. Study Duration: from April 2017 to Oct 2017. Sampling: 600 patients were selected through Consecutive sampling. Statistical Analysis: Descriptive statistics like mean, Standard deviation, minimum, and maximum were calculated Using SPSS version 22.Mean of two genders was compared using t-test setting <0.05 as level of significance. Results: Mean serum vitamin –D level was 16.11+10.07ng/ml in men while it was 16.63+11.73 ng/ml in women. 62% of the study population was found deficient (<20ng/ml) while 16.33% were having insufficient levels (<30ng/ml) and only 12% showed normal levels (30-50ng/ml). There was no significant difference between the two genders, p value 0.59 Conclusion: Vitamin –D deficiency is very common in both genders with no significant difference between males and females.

Fish meat is a common and broadly used food due to its high nutritional values yet the bones and flavour of fresh fish can be unpleasant. The unpleasant fishy flavour makes it difficult to handle and process. The fishy flavour is as a result of microbial presence and growth. Studies associated with microbial contaminations have concentrated more on the carcass. Such contaminations which affect the microbiological status of processed products can emanate from spices and other non-meat ingredients, environment, equipment and handlers. The successful application of processing/preservation technology results in the conservation of desirable qualities in stabilized and varietal fish products. This study sought to use fish in the manufacture of frankfurter-type sausages, which could have improved preservation characteristics without any adverse effects on sensory properties. The nutritional composition and microbiological safety of fresh fish and sausages were determined using the methods described by AOAC and ICMSF respectively. The study showed that, catfish sausages were higher in protein (15.69 %) and were lower in fat (10.66%) compared to the other sausages. Total Viable Counts (TVC) were within the accepted limits (106 and 107cfu/g) for fish and pork respectively. E. coli was not detected in any of the treatments during frozen storage for 6 weeks. It was concluded that catfish frankfurter has high nutritive value because it contained less fat but with higher crude protein. Like pork frankfurters, both catfish and mackerel sausages could be stored for six weeks without any negative effects on microbial quality.

Bone remodeling processes in rheumatoid arthritis (RA) depend mainly on the action of three types of cells. Osteoblasts are responsible for the formation of new bone, osteoclasts degrade mineralized bone and osteocytes regulate and maintain the bone homeostasis. Except, many other cell populations become pathologically activated in the inflamed microenvironment of the joint. The role of megakaryocytes and platelets in RA is poorly clarified. In the present study the presence of MK in the synovium and cartilage was observed in a model of arthritis induced in normal and complement depleted mice.

Cranial vault is the case surrounding the brain. Its structure differs in newborns than in adults in some aspects. Such differences should be clear for both health and family members. Moreover, the anatomy and embryology of fetal skull take a little attention in the previous literature and textbooks. Therefore, this short review aimed to clarify some aspects of anatomy and clinical importance of cranial vault features in newborns. The newborn vault is formed of multiple separate flat bones connected by fibrous tissues with wide soft gaps called fontanelles. Development of bones of skull vault is closely correlated with the expanding growth of the underlying brain. Such brain shouldn't be struggled by continuous tightening of the newborns' vault. Also, the newborn skull could be affected even by a fixed sleeping position.

Introduction: The use of non-medicinal facilities for correcting processes in various pathological conditions is one of the most urgent problems of modern medicine. Purpose of the Work: To study the effect of low-intensity infrared laser radiation on reparative bone formation and angiogenesis in bone regeneration which is formed in treatment of fractures under conditions of transosseous osteosynthesis. Material and Methods: A tibia fracture was modeled experimentally in rats in the control and experimental groups. Reposition and fixation of fragments were performed. The fracture zone in the experimental group animals was exposed to the impact of pulsed infrared laser irradiation of low intensity. Animals from the control group underwent the impact simulation. The operated bones were investigated using the methods of X-ray, light and electron microscopy, X-ray electron probe microanalysis. Results: It was established that laser radiation exposure sessions activated fibrillogenesis and angiogenesis, accelerated compacting of newly formed bone tissue and increased its maturity while primary fracture healing occurred. Prolonged capillary dilatation and endothelium-dependent vasodilation, intensive capillarogenesis were noted after sessions of laser therapy in bone regeneration. Endothelial outgrowth was formed in the lumen of the vessels forming capillary buds that propagate along the “mother” vessels (endovascular capillarogenesis). Conclusion: The data obtained revealed a possible mechanism of laser radiation exposure at the level of a whole organism and proved the effectiveness of its application in clinical practice at the early stages of patient rehabilitation under conditions of transosseous osteosynthesis.

Neuropilins are transmembrane glycoproteins that act as receptors for vascular endothelial growth factors (VEGF) and are involved in the process of tumor angiogenesis. Its importance in hematological malignancies such as acute leukemia (AL) remains to be elucidated. The aim of this study was to evaluate the significance of neuropilin-1 expression in acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) patients by flowcytometry and the difference between both groups of acute leukemia. Bone marrow aspirates of 52 patients with acute leukemia, 29 patients with de novo AML and 23 ALL patients were examined in this study. 15 subjects with non-hematological malignancy serving as the control group were also included. Neuropilin-1 expression by flow cytometry showed a highly significant increase in de novo AML and ALL patients with a mean of 37.9 ± 20.92% and 32.33±19.8%, respectively, compared to control group’s mean of 11.51 ± 3.04% (p= 0.001, 0.006). There were no statistically significanct difference between ALL and AML patients (p= 0.76). Neuropilin-1 surface expression by flowcytometry showed a significant positive correlation with total leukocyte count, bone marrow blast percentage, CD45 and CD14 and negative correlation with hemoglobin level, RBCs count in AML patients. In ALL patients, positive significant correlations were found with bone marrow blast percentage and negative correlation with hemoglobin level, RBCs count. Neuropilin-1expression was detected significantly in acute leukemias and it is related to the disease severity.

The aim of the present study was to compare mandibular neurovascular canal anatomy in human and great apes by using cone beam computed tomography (CBCT). The anatomical variability of mandibular neurovascular canals (mandibular, incisive and lingual canals) of 129 modern humans and great apes (Homo, Pan and Gorilla) were analyzed by linear measurements on CBCT images. The Kruskal-Wallis non-parametric test and Dunn’s all pairs for joint ranks were applied to compare the variability of mandibular canals among these groups. Human, Chimpanzee and Gorilla groups showed significant differences in the dimensions of the mandibular canal, mental foramen, incisive canal, lingual canal and anterior mandibular bone width. Bifid mandibular canals and anterior loops were the anatomical variations most frequently observed in the Gorilla. Humans had a larger mental foramen and a distinctive incisive canal. The latter could not be identified in the Gorilla group. The variability in the anatomy within mandibles of human and non-human primates, shows different forms in the neurovascular structures. In comparison to the mandible of great apes, the incisive canal is suggested to be a feature unique to the human mandible.

Up till now, chitosan has confirmed its versatile application in skin, cartilage and bone tissue engineering, as well as in drug delivery applications. This study is focused on enzymatic degradation of porous chitosan structures usually designed for mentioned purposes. In vitro degradation was monitored during four weeks of incubation at physiological temperature and in two different media, phosphate buffer saline solution and water. The scaffolds were characterised before and after enzymatic degradation using scanning electron microscopy and infrared spectroscopy with Fourier transformations (FTIR). According to the gravimetric analysis, higher weight loss of chitosan scaffolds was observed in buffered medium with respect to the water. The results implied that the total weight loss obtained in buffer involves physical dissolution of chitosan and lysozyme cleavage of glycoside bond. Importantly, FTIR identification of chitosan scaffolds after enzymatic degradation indicated the absence of lysozyme activity in water, indicating that weight loss is a result of the chitosan dissolution. This finding greatly impacts design of degradation experiments and characterisation of degradation behaviour of chitosan-based materials utilised as implants or drug delivery systems.

The Agency for Toxic Substances and Disease Registry (ATSDR) lists cadmium as one of its priority hazardous substances. The agency conducted a comprehensive literature review of cadmium and used the information to develop a toxicological profile that identified the full range of health effects associated with exposure to cadmium. It included an assessment that identified screening levels, termed health guidance values or minimal risk levels (MRLs), below which adverse health effects are not expected. In this paper, we describe how MRLs for cadmium are derived. For the acute inhalation MRL, the traditional no observed adverse effect level or lowest observed adverse effect level (NOAEL/LOAEL) approach is used; for the oral intermediate MRL, the benchmark dose (BMD) approach is used. MRLs were developed for the most sensitive route-specific end points, other than mortality and cancer that were sufficiently supported and justified by the data. These included an acute duration (1–14 day exposure) inhalation MRL of 0.03 µg Cd/m3 for alveolar histiocytic infiltration and focal inflammation in alveolar septa and an intermediate duration (15–365 day exposure) oral MRL of 0.5 µg Cd/kg/day for decreased bone mineral density

We report a case of cholesteatoma associated with unilateral congenital aural atresia (CAA) and microtia, resulting in extracranial complication. A 13-year-old girl presented with right ear purulent discharge from pre and post auricular area with mastoid tenderness. On clinical examination, she had right grade II microtia with pre-auricular skin tag and healed scar tissue in periauricular region. On High Resolution Computerized Tomography (HRCT) scan of temporal bones, there was CAA of right ear with extensive cholesteatoma in middle ear cleft. The cholesteatoma was subsequently removed by radical mastoidectomy with uneventful post-operative period. Cholesteatoma associated with CAA may remain undiagnosed in early childhood resulting in life threatening temporal and intracranial complications.

Objectives The aim of this study was to compare the functional outcomes (including swallowing, respiration and phonation) of supraglottic horizontal laryngectomy (SGHL) and supracricoid partial laryngectomy (SCPL). Methods The clinical and pathological data were evaluated for 36 previously untreated patients who were diagnosed with laryngeal carcinoma and underwent SGHL or SCPL at the Department of Otorhinolaryngology-Istanbul Training and Research Hospital from 2010 to 2016. Removal of the nasogastric tube, decannulation and hospitalisation times were recorded in both groups and postoperative complications were noted. Results The SGHL group contained 15 patients and the SCPL group contained 21 patients (14 cases of cricohyoidoepiglottopexy (CHEP) and 7 cases of cricohyoidopexy (CHP)). The mean age of the subjects was 57.4 years in the SGHL group, and 59.7 in the SCPL group. Patients in the SGHL group were decannulated after 65.2 days, whereas the average decannulation time was 72.6 days in the SCPL group. This difference in decannulation time between the groups was not statistically significant (p>0.05). The mean hospitalisation time was 23 days, with no statistically significant difference between the groups (>0.05). The nasogastric tube was removed from the patients after 37.9 days in the SGHL group and after 35.8 days in the SCPL group. No statistically significant difference was determined in the time to start feeding between the groups (p>0.05). Surgical wound infection, the occurrence of pharyngo-cutaneous fistulas and rupture of the pexy sutures were complications. Conclusion Functional outcomes of SCPL were similar to those of patients who underwent SGHL. The preservation of the hyoid bone is the most important consideration for preserving the swallowing function.

Background and Context: Autologous bone grafts require a second surgical exposure to harvest the graft with a significant risk of post-operative complications and donor site morbidity. Employment of allografts potentially eliminates donor site morbidity but carries the potential of causing foreign body immune reactions with a high rate of rejection and failures. Hence, Alloplasts have emerged as novel materials to overcome the drawbacks of autogenous and allogenous bone grafts. Today’s advanced dentistry is enterprising a putty form of calcium phosphosilicate (CPS) into several aspects of reconstructive domain of dentistry including the sinus augmentation procedures, osseous regeneration of periodontal bone defects, cystic cavity defects and alveolar socket preservation. This eccentric multifaceted study was planned as an honest effort on the path of proving the efficiency of CPS as an alloplastic bioactive graft material and aimed at quantitative evaluation of regenerated bone radiographically using Cone Beam Computed Tomography (CBCT) scans following sinus augmentation procedures. Materials and Methods: A total of 20 sinus augmentations were carried-out in 17 patients satisfying the criteria (inclusion and exclusion) requiring placement of implants in atrophic maxilla and in other situations of anatomic constraints. The graft material used was calcium phosphosilicate (CPS) putty (Nova bone dental putty, Novabone products, Alachua, Fla). The residual bone height was recorded using CBCT scans and a computer based software where the measurements were made from the crest of the ridge till the sinus floor lining. The patients were assessed clinically at immediate post-operative, 1 week, 1 month, 3 months and 6 months follow-up recalls post-operatively. Radiographic assessment for bone height was done pre-operatively and at 6 months follow-up recall post-operatively using Cone Beam Computer Tomography scans. Results: The post-treatment bone height (11.76+0.97mm) was found to be significantly higher than the pre-treatment bone height (6.8 +0.70mm) in indirect sinus augmentation procedures (t=14.4, p<0.005). In case of direct sinus augmentation group also, the post-treatment bone height (11.27 +0.71mm) came-out to be significantly higher than the pre-treatment bone height (2.44 +0.81mm) (t=32.17, p<0.005). The post-treatment bone grafted sinus floor measurements (1107.6 + 155.6mm) were also found to be significantly higher than the original sinus floor measurements of bone density (Grayscale values) (412+ 65.5mm) (t=16.6, p<0.001) in case of indirect sinus augmentation procedures. Similarly, the post-treatment bone grafted sinus floor measurements (1169.6+136.7mm) were found to be significantly higher than the original sinus floor measurements of bone density (Grayscale values) (416.4+ 0.70mm) (t=17.9, p<0.001) in case of direct sinus augmentation group. Conclusion: Calcium Phosphosilicate (CPS) was accepted well at the recipient sites without any complications demonstrating its efficiency and reliability in sinus augmentation procedures.

Context: The present study was undertaken to do a comparative evaluation of the role of Cone Beam Computed Tomography (CBCT) imaging and Orthopantomography (OPG) for pre-operative implant planning in combination with sinus grafting procedures in order to assess sinus anatomy and morphology and the existing bone height in three dimensions. Aims: To assess sinus anatomy and morphology and the existing bone height in three dimensions. Materials and Methods: Pre-operative assessment of maxillary sinuses for implant planning using CBCT imaging was performed on 20 sinuses (17 patients). These patients were subjected to orthopantomographs and CBCT imaging both pre-operatively and post-operatively. CBCT imaging helped to decide the type of sinus augmentation procedure best suited for the patients as per the individual needs and depending on the residual alveolar bone height, timing of implant placement, sinus morphology, anticipation of complication and comparative analysis between pre-and post-procedural gain in vertical alveolar bone height and increase in bone density. Statistical Analysis: The results were tabulated and statistically analyzed using Paired and Unpaired t-tests. Results: In the majority of cases, there was a concordance between the treatment type based on pre-operative and post-operative CBCT scans. The assessment of sinus morphology revealed a significantly higher detection rate of abberations in the form of sinus mucosal hypertrophy and septae on CBCT which were imperceptible on routine radiographs. The most appealing result was that vertical alveolar bone height could be measured precisely and there was a significant increase in surgical confidence and a significantly better prediction of complications when using CBCT imaging. Conclusions: A pre-operative planning based on CBCT imaging seems to improve sinus diagnostics and helps to execute a better treatment plan. Also, it is a good tool for the comparison of vertical alveolar bone height pre-and post-operatively following sinus augmentation procedures using various graft materials.

Purpose: The aim of the study was to analyze the spatial relationship between the sinus floor and the alveolar bone of maxillary premolars and molars in order to assess the amount of basal bone available for immediate extraction placement of endosseous implants. Materials and Methods: All the cone-beam computerized tomographic (CBCT) scans taken over a three-year period at four centers were identified. The subsinus bone height (SBH) was evaluated by measuring the distance between the sinus floor and the first and second premolar root apexes. The interradicular septum bone height (ISBH) of all the first and second molars was also measured, and the presence or absence of sinus-floor invagination between the molar roots was recorded. Results: Five hundred twenty-six (526) CBCT scans of fully or partially dentate maxillary arches were examined. The root apex was inside the sinus of 1.8% of all the first premolars. It approximated the sinus floor of 5.3% of them, and the distance between the two points was between 1 and 3mm of 20%, between 3 and 7mm for 34.1%, and more than 7mm for 34.1%. For the second premolars, the findings were 13.5% (inside the sinus), 10.5% (touching the sinus), 32.8% (1-3mm of distance) 28% (3-7 mm), and 15.2% (more than 7mm). Root invagination was noted in 50.2% of the first molars and 43.1% of the second molars, with the ISBHs ranging from 13.4% to 56.9%. Conclusion: Radiological evaluation is essential to determining whether implants should be placed immediately after extraction of maxillary premolars and molars.

Background: Gingival crevicular fluid (GCF) is regarded as a promising medium for detection of periodontal disease activity. bone loss is a major feature of periodontal disease, although we are unable to determine the time of this bone loss and therefore periodontal disease activity. During orthodontic treatment small forces are applied, resulting in bone remodeling which allows tooth movement. Orthodontic model may be used as a preliminary stage in evaluating gingival crevicular fluid role in bone turnover. Aims: To detect GCF and to monitor it's volume and flow rate following orthodontic activation, and to determine at what stage inflammation and bone resorption reach their maximum. Materials and Methods: GCF samples were collected from 10 adult orthodontic patients (mean age = 22.3 , range 20-24year) on 3,7,10,14,21,28,35 days after activation of orthodontic appliance, from the tooth surface where bone resorption was expected to occur. A total of 330 GCF sample were collected using filter paper strip, the volume measured by weighing. Results: An insignificant increase in GCF volume and flow rate was noted in the tenth day after activation of the orthodontic appliance activation. At 35 days GCF reached its minimum flow rate. There was considerable variation between subjects and between the same subject on different days Conclusion: Increase in GCF volume and flow rate reflects the effect of orthodontic adjustment rather than oral hygiene, as there were no clinical inflammatory changes during the period of orthodontic treatment studied.

Objective: We compared preoperative data of physical examination, CT and diffusion MRI findings of temporal bone with our intraoperative observations. We investigated the diagnostic efficiency of single-shot spin echo echoplanar diffusion MRI (SS SE EPI) on primary cholesteatoma. Methods: 33 patients with chronic otitis media who had been admitted to Otolaryngology Department of Haydarpasa Numune Training and Research Hospital between June 2010 and September 2011 were involved in this study. All patients did undergo otoscopic and audiometric examination. After imaging of temporal bone by CT and diffusion MRI, patients were operated and intraoperative observations were recorded. Patients with intraoperatively approved cholesteatoma were defined as group 1 and those without cholesteatoma were defined as group 2. Perioperative and preoperative findings of physical examination, CT and MRI of all patients were compared one by one. Results: Positive physical examination findings have been superior to MRI and CT, having a sensitivity of 96%, specifity of 87.5%, positive predictive value of 96% and negative predictive value of 87.5%. In terms of effectiveness of MRI in diagnosing intraoperative cholesteatoma, we had a sensitivity of 80%, specifity of 50%, positive predictive value of 83.3% and negative predictive value of 44.4%. These values are also lower than previously reported results. Conclusion: When we had preoperative suspection of cholesteatoma on physical examination and diffusion MRI, in addition with bone tissue erosion on CT, we found that physical examination is superior to MRI and CT in terms of capability of diagnosing the disease.

We report 2 cases of primary hyperoxalurea who presented with refractory anaemia, nephrolithiasis, renal failure warranting repeated renal transplantation in one of the cases. Renal biopsy of the patients revealed crystals of calcium oxalate in the tubules. The same crystals were also visualized in bone marrow biopsy which confirmed the diagnosis of systemic oxalosis. We conclude that Primary hyperoxalurea may rarely cause anemia secondary to calcium oxalate crystal deposition in the bone marrow.

Acute lymphoblastic leukemia (ALL) is a rapid form of leukemia characterized by clonal proliferation and accumulation of immature hematopoietic stem cells of the lymphoid lineage in the bone marrow as well as peripheral blood. Chromosomal aberrations identified in childhood ALL have an important role in disease diagnosis, prognosis and management. We present the results of hematologic, immunophenotypic, cytogenetic, FISH and Multiplex RT-PCR analysis of a 6-year-old boy diagnosed with B-cell precursor Acute Lymphoblastic Leukemia (BCP- ALL). In this study, we identified a novel chromosomal translocation t(10;15)(q22;q22) by cytogenetic and FISH analysis. To the best of our knowledge, this is the first report of this novel chromosomal translocation in this subset of ALL and has not yet been reported elsewhere. This rearrangement may include certain cancer associated tumor suppressor gene(s) or genes involved in apoptosis and transcription regulation, which on loss of normal function may lead to leukaemogenesis.

Background: Heart valves share developmental signaling pathways with cartilage and bone. While calcific aortic valve disease (CAVD) has been associated with valve calcification and stenosis, suggestive of osteogenesis, myxomatous mitral valve disease (MMVD) is characterized by net matrix degradation, exuberant deposition of proteoglycan, and valve regurgitation. Methods: We determined the presence of cartilage-abundant proteoglycan, aggrecan; cartilage-specific type II collagen; chondrogenic transcription factor, Sox9; and osteogenic transcription factor, Runx2 in human normal and myxomatous mitral valve leaflets by immunohistochemistry. Results and Conclusions: Myxomatous, but not normal, mitral valves demonstrated sharp focal areas that were abundant in aggrecan, type II collagen, and Sox9. These focal areas co-localized with areas of myxomatous pathologic change on Movat staining. Some cells in these areas had a round and hypertrophic morphology reminiscent of chondrocytes. Runx2 was only weakly present in normal and myxomatous mitral valves. These findings suggest a focal pathologic process in MMVD that mimics chondrogenesis.
