Overall PCP adherence to H. pylori management guidelines is low. Public health agencies should advance educational initiatives aimed at closing these gaps.
Lymphocytic gastritis (LG) is associated with helicobacter pylori (Hp) and celiac disease (CD). We aimed to clarify
the relationship between Hp infection and CD by defining a unique histopathology profile of LG in these two diseases.
Forty patients who underwent upper endoscopy were divided into four groups: eight controls, ten active CD patients
without Hp, twelve CD negative with Hp, and ten active CD with Hp infection. Antral samples were assessed by
immunohistochemical staining for CD20, CD3, CD4, CD8, CD57, CNA42, and Ki67 for lymphoid aggregates,
intraepithelial lymphocytes (IELs) number, density of lamina propria (LP) lymphocytes, and inflammatory glandular
involvement. Only IELs positive for CD3 and CD8 were increased significantly in CD patients with or without Hp infection.
Hp did not contribute to the number of CD8 IELs. In complicated cases with Hp and suspicious for CD, the number of
CD8+ IELs hints toward a CD rather than Hp infection.
Because of a high incidence of concurrent cholelithiasis, many patients with a periampullary tumor seen during ERCP are misdiagnosed earlier (by clinical evaluation and non-invasive imaging) as having choledocholithiasis only. However, the accuracy of endoscopy and biopsy is also limited. This limitation must be considered when evaluating the optimal management of patients with suspected periampullary tumor.
Scabies is not a notifiable disease in most countries. As a result the data on its epidemiologic characteristics are limited. In the Israel Defense Force, compulsory reporting of individual cases has been required for years, and in this study the epidemiology of the disease is examined for the years 1968-1988. A moderate epidemic occurred between 1969 and 1973, and was followed by a return to the previous low incidence. In 1982 a massive outbreak began, and peaked from 1985-1986. From 1987 to 1988, the incidence of infestation has markedly declined. A seasonal pattern of morbidity was evident during epidemic periods only; maximum incidence occurred during the winter months. These data are compared with those described in other countries and provide a more complete picture of the epidemiology of scabies based on individually reported cases.
Antiplatelet drugs may increase the risk of bleeding induced by gastrointestinal endoscopic procedures. The antiplatelet effect of cyclooxygenase-1 inhibitors lasts less than 4 h. Skin and colonic bleeding times are prolonged for 3 and 5 days after aspirin and ticlopidine withdrawal respectively. Major bleeding from endoscopic biopsies is extremely rare. In the four recent largest series, the general incidence of polypectomy-induced major bleeding was 0.11–0.42%. In more than half of the cases the bleeding was delayed, usually up to 2 weeks after the endoscopy. Although three retrospective studies suggested that aspirin does not increase the risk of polypectomy-induced bleeding, the power of these studies is limited. Similarly, it is difficult to draw conclusions from the two studies that assessed the risk of aspirin use during sphincterotomy. Aspirin withdrawal may be harmful in susceptible patients, mainly if it is for more than 7 days. There is no indication to stop aspirin before esophagogastroduodenoscopy, which may reveal aspirin-induced lesions. We recommend discontinuation of aspirin 4–7 days (according to the cardiovascular risk) before other endoscopic procedures. When aspirin is indicated for primary prevention, it can be resumed 14 and 10 days after polypectomy and sphincterotomy respectively. In cases of secondary prevention, it should be resumed after 1 week.
Aberrant MAP-kinase pathway activity is associated with active celiac disease (CD). Further studies should examine the potential role of this aberration in pathogenesis of CD.
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.
