Organic or Psychiatric Disease? A Misdiagnosed Superior Mesenteric Artery Syndrome

Aug 2016 DOI 10.14302/issn.2379-7835.ijn-16-1154

Superior mesenteric artery syndrome 1234 is a rare disorder characterised by a compression of the duodenum because of the reduced angle between the aorta and superior mesenteric artery. The disease is clinically characterised by abdominal pain, lack of appetite, vomiting and anorexia; some of these symptoms also characterise eating disorders. We report a case of a young female patient presenting with abdominal pain, loss of appetite and chronic loss of weight which led to misdiagnosis of anorexia nervosa; ultrasound with echo color Doppler methodology has subsequently allowed the correct diagnosis.

Capsaicin: A Potential Therapy Adjuvant for Intestinal Bowel Disease

Most of the patients with inflammatory bowel disease avoid pepper or spicy food, alleging that this condiment causes anal sensation of burning and accelerates intestinal movements. Capsaicin is the main bioactive component of peppers responsible for the pungent flavor that characterizes red peppers. Capsaicin has been related to several biological effects, including decreased body fat, antianti-inflammatory, anticarcinogenic, antioxidant activites and modulator of intestinal motility. These actions mostly are due to its role as an agonist of the transient receptor potential vanilloid 1 (TRPV1), expressed in the mesenteric nervous system and epithelial cells of the colon. Nonetheless, the anti-inflammatory action of capsaicin is also related to its role in activating the peroxisomal proliferator-activated receptor gamma (PPAR-γ). Topical capsaicin formulations are already used for pain management, but oral administration of capsaicin is rare. Here, we discuss the main actions of capsaicin that could interfere with the symptoms and severity of IBD. Although animal experiments suggest a beneficial effect of capsaicin on colitis, clinical studies exploring the potential analgesic and anti-inflammatory of capsaicin on Crohn or Ulcerative Colitis are scarce. We concluded that there is no evidence that capsaicin aggravates IBD symptoms or severity. On the opposite, experimental studies suggest that capsaicin could reduce intestinal inflammation by a mechanism that could involve not only the TRPV1 receptor but also PPAR γ. However, clinical studies are still scarce, and data regarding capsaicin concentrations, routes of administration, and long-term side-effects need to be better understood before its use.

A Case of Collision Tumor of MALT Lymphoma and Poorly Differentiated Adenocarcinoma Diagnosed Incidentally After Appendectomy for a Clinical Presentation of Acute Appendicitis.

Jan 2019 DOI 10.14302/issn.2641-5518.jcci-18-2552

This report presents a case of collision tumors of low-grade B-cell lymphoma and poorly differentiated adenocarcinoma in the caceum of a 63-year-old woman. Lymphoma was diagnosed incidentally after appendectomy for a clinical presentation of acute appendicitis. Imaging follow-up demonstrated mesenteric lymphadenopathy and liver lesions, and all surgically resected regional mesenteric lymph nodes and liver biopsy were found to be infiltrated by both mucosa-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma. Systemic chemotherapy was administered for advanced colonic adenocarcinoma with liver metastases. The occurrence of synchronous lymphoma and adenocarcinoma of the colorectal region is rare, and this is a previously unreported case of a patient that was diagnosed during management of acute appendicitis.  

An Update on Hemocytes in Biomphalaria Snails

May 2016 DOI 10.14302/issn.2372-6601.jhor-14-401

The hemocyte is a major immunological cell of molluscs. Much of the immunological phenomena associated with molluscan immunology can be attributed to cellular immunity associated with these cells suspended in the hemolymph. These cells are often referred to as amoebocytes or hemocytes. Such cells are of great importance to immune mechanisms associated withBiomphalaria snails. The Biomphalaria snail is the main vector of the important trematode parasite Schistosoma mansoni. This is a waterborne parasite that affects about 200 million people globally and puts countless other millions at risk of infection. Larval stages of the parasite are released from the snail in tainted waters and the larval cercarial stage actively penetrates the skin of humans and other vertebrates. Larvae migrate via the venous system to vital organs associated with the heaptic portal and mesenteric blood vessels. Larvae develop into sexually mature male and female adult worms that live in major venous blood vessels. The worms mate and produce eggs that lodge in major organs such as the spleen, liver, and intestines. Eggs produce extensive granulomas that cause cirrhosis and other pathological conditions in the affected organs.
