Despite the publication of guidelines, misuse of gastric acid suppressants continues to occur, even by attending physicians. More complete understanding of the need and occasion for SUP use should result in more cautious use.
Strongyloides stercoralis is endemic to many tropical regions; however, there is limited knowledge concerning the clinical implication of this helminth, particularly in urban medical centers. We report a case series of strongyloidiasis in our urban medical center in New York City. Patients over the age of 18 years who were examined in our institution from January 1998 to May 2011 were identified by electronic medical record search using International Classification of Diseases, 9th Revision codes. We identified 22 cases of S. stercoralis. Eleven patients were men and 11 were women, with the average age at diagnosis being 62.4 years. Fourteen patients emigrated from the Caribbean, one from Nepal, five were blacks born in the USA, and two did not have their birthplace documented. The main presenting complaints were diarrhea (9/22), abdominal pain (6/22), vomiting (7/22), and weight loss (8/22). Seventeen patients demonstrated eosinophilia. Four patients were positive for human T-lymphotropic virus-1 antibodies, and three patients were infected with HIV. Diagnosis was made with stool examination (19/22), bronchoalveolar lavage (1/22), gastric biopsy (1/22), and duodenal biopsy (3/22). Among six patients who had upper endoscopy performed, the findings commonly included gastritis and gastric and duodenal ulcers. After treatment, 12/22 showed resolution of symptoms. Although a diagnostic approach tends to start with stool collections, consideration of upper endoscopy with biopsy in symptomatic patients is advisable. The absence of eosinophilia should not deter the clinician from seeking a diagnosis. Although often not done, ascertaining HIV and human T-lymphotropic virus-1 status should be part of the work-up.
We believe the Gastroenterology Core Curriculum provides trainees with essential tools for becoming an autonomous gastroenterologist who can appreciate various learning modalities.
With greater research, physicians will better recognize IBD phenotypes at highest risk of PSC and hopefully identify complications of PSC, including cholangiocarcinoma.
Amyloidosis is commonly systemic, occasionally organlimited, and rarely a solitary localized mass. The latter, commonly referred to as tumoral amyloidosis, is described as occurring in nearly every organ/tissue. Only a few reports of gastric amyloidosis exist today. We describe a 72 year-old black male from Barbados presenting with 3 d of diffuse abdominal pain. His medical history included Non-Hodgkin's Lymphoma diagnosed five years ago, status-post six rounds of cyclophosphamide, adriamycin, vincristine, prednisone chemotherapy, and currently was in remission. On computed tomography scan of the abdomen, thickening and calcification of the gastric wall was noted along with pneumatosis. On esophagogastroduodenoscopy, a large circumferential friable mass was seen from the gastroesophageal junction to the body. A large nonbleeding 3 cm polyp was also seen in post bulbar area of duodenum. Biopsies were stained with Congo red and gave green birefringence under polarized light, consistent with tumoral amyloidosis. Positron emission tomography scan revealed diffuse gastric mucosa uptake compatible with gastric malignancy without metastatic foci. Treatment for gastric amyloidomas has presently been one of observation or, at most, resection of the amyloid mass. It is not known if our patient required the same approach or if this warranted the re-institution of chemotherapy for Non-Hodgkin's Lymphoma. Until more reports of tumoral amyloidosis are made known, treatment as well as prognosis remain uncertain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
