BACKGROUND:

Small bowel (SB) capsule endoscopy (CE) studies provide data on both gastric and SB transit times (GTT and SBTT, respectively). This study aimed to evaluate the influence of demographic and clinical parameters on the GTT and SBTT. Transit times for two generations of capsules (Pillcam SB2 and SB3) were also compared. Read more

Levan is a commonly used dietary fiber of the fructans group. Its impact on
health remains undetermined. This double blind controlled study aimed to
investigate the effect of 8 weeks’ daily consumption of 500 mL of natural orange
juice enriched with 11.25 g of levan compared to the same amount of natural
orange juice without levan on weight, gastrointestinal symptoms and metabolic
profiles of 48 healthy volunteers. Read more

Monogenic periodic fever syndromes are characterized by recurrent episodes of
fever, accompanied by localized inflammatory manifestations. Among them, familial
Mediterranean fever (FMF) is the most studied and is by far the most prevalent
periodic fever syndrome in Israel. We present a diagnostic workup of a patient
suffering from a periodic fever syndrome, initially thought to be FMF and
characterized by attacks of fever, severe abdominal pain, a migratory
erythematous rash and conjunctivitis. Read more

OBJECTIVE: Increased metabolic rate may play a role in cancer cachexia,
especially when caloric intake is significantly reduced. We studied the effect of
tumor load on resting energy expenditure (REE) in patients with pancreatic cancer
after normalizing for their daily caloric intake and body composition.
METHODS: The cross-sectional study included 45 patients with pancreatic cancer
(15 postoperation) and 75 controls. Resting energy expenditure was measured by
indirect calorimetry, body composition was measured by dual-energy x-ray
absorptiometry, and energy intake was measured by 3-day food records. Read more

Abstract

The role of microsatellite instability and defects in DNA mismatch repair mechanism in the pathogenesis of gastric lymphoma of mucosa-associated lymphoid tissue (MALT) type is still controversial, as both negative and positive findings have been reported. This may be explained mainly by arbitrary selection of the tested loci, the use of various techniques of microsatellite instability analysis and by different definitions of replication error positive phenotype.

Abstract

BACKGROUND AND OBJECTIVES: Chronic gastrointestinal (GI) bleeding is the leading cause of iron deficiency anaemia (IDA) in men older than 50 years and post-menopausal women. There is a scarcity of data regarding IDA patients without GI symptoms or signs. We conducted a prospective study to determine the prevalence and the locations of the GI tract lesions in patients with asymptomatic IDA.

Abstract

Development of multiple tumors of different histopathologic types may suggest a profound generalized genetic defect, such as malfunction of DNA mismatch repair (MMR) mechanism. Defects in this mechanism are best reflected in microsatellite instability (MSI). We aimed to determine the role of MSI in a group of patients with dual malignancies and compared the data with that of patients with a single malignancy.

Abstract

BACKGROUND: As suggested by observational and animal studies, heparin has antiinflammatory effects that could prevent acute post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Low-molecular-weight heparin did not reduce the incidence of post-ERCP pancreatitis in a controlled study. The current study aimed to determine whether prophylactic administration of low-dose unfractionated heparin, which has potentially more antiinflammatory capability, can prevent acute post-ERCP pancreatitis.
