With the changing epidemiology of Crohn's disease (CD) and intestinal tuberculosis (ITB), we are in an era where the difficulty facing physicians in discriminating between the two diseases has increased, and the morbidity and mortality resulting from a delayed diagnosis or misdiagnosis is considerably high. In this article, we examine the changing trends in the epidemiology of CD and ITB, in addition to clinical features that aid in the differentiation of both diseases. The value of various laboratory, ...

The present article describes three difficult cases of recurrent bleeding from obscure causes, followed by a review of the pitfalls and pharmacological management of obscure gastrointestinal bleeding. All three patients underwent multiple investigations. An intervening complicating diagnosis or antiplatelet drugs may have compounded long-term bleeding in two of the cases. A bleeding angiodysplasia was confirmed in one case but was aggravated by the need for anticoagulation. After multiple transfusions ...

One manifestation of portal hypertension, gastroesophageal varices, accounts for significant morbidity and mortality caused by bleeding in this patient population. Although uncommon, ectopic varices can involve any other part of the GI tract and are challenging for clinicians to identify, diagnose, and manage. Missing or misinterpreting these lesions can carry grave consequences, and the management options for these lesions are unclear in the literature. In this article, we review the vascular anatomy ...

The authors propose an incremental step toward combining the insights of modern portfolio theory with some of the propensities documented in the literature on behavioral finance. They develop a goals-based wealth management approach that finds a specific subportfolio to address each of an investor's goals and then derive the least-cost solution. They relate the closed-form solution for the one-period, two-asset problem to the mean–variance efficient frontier. Consistent with the "lockbox separation" ...

Bleeding in the upper gastrointestinal tract is a common medical problem, with an incidence of 48 to 160 cases per 1000 adults per year and a mortality rate of 5% to 14%. The risk of gastrointestinal bleeding is increased with the use of antiplatelet medications including aspirin and clopidogrel, as well as warfarin or a combination of these medications. The recurrence rate for bleeding in patients who continue to take aspirin after an episode of peptic ulcer disease-related bleeding can reach up ...

BACKGROUND: Patients with upper gastrointestinal bleeding (UGIB) require an early, tailored approach best guided by knowledge of the bleeding lesion, especially a variceal versus a nonvariceal source. OBJECTIVE: To identify, by investigating a large national registry, variables that would be predictive of a variceal origin of UGIB using clinical parameters before endoscopic evaluation. METHODS: A retrospective study was conducted in 21 Canadian hospitals during the period from January 2004 until ...

Self-expandable metal stents (SEMS) are used in patients with malignant distal biliary obstruction; trials that compared covered and uncovered SEMS reported different results because of heterogeneous designs and patient populations. These studies compared patency of uncovered SEMS and covered SEMS, along with rates of pancreatitis, cholecystitis, cholangitis, SEMS migration, bleeding, perforation, and recurrent biliary obstruction.We performed a meta-analysis to compare the effects of covered and ...

Using the successive elimination procedure presented herein, the degrees of the input–output (I/O) polynomials as well as the number of assembly configurations for all 71 mechanisms resulting from 16 8-link kinematic chains are presented. It is shown that the displacement analysis problems for these mechanisms can be classified into nine distinct structures each ...

To exploit return predictability via dynamic asset allocation, investors face the important practical issue of how often to rebalance their portfolios. More frequent rebalancing uses statistically and economically significant short-horizon return predictability to aggressively pursue the dynamic investment opportunities afforded by changes in expected returns. However, the degree of return predictability typically appears stronger at longer horizons, which, along with lower transaction costs, favors ...

Abstract This cross‐sectional study examined the relationship between work‐related stress, cortisol, and C ‐reactive protein ( CRP ) in predicting metabolic syndrome ( M tS). Self‐reported work stress measured by the effort reward imbalance ratio ( ERI ), anthropometric data, CRP , and saliva cortisol were collected from 204 healthy Jordanian male workers. ERI and cortisol were significantly associated with the presence of MtS ( OR = 4.74, 95% CI : 2.13–10.55; OR = 3.03, 95% CI : 2.08–4.40; OR = 11.50, 95% CI : 2.16–59.14, ...
