he incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. it occurs mostly in patients in the 6th decade of their life. of all the small bowel diverticuli, jejunal diverticulum is the most common type. this rare entity is usually asymptomatic. however, they may cause chronic non-specific symptoms for a long period of time ...

A total of 2848 study sites, with about 500 people in each, were randomly sampled for this investigation which covered a total population of 1 477 742. By stool examinations using the Kato-Katz thick-smear and larval-culture techniques, overall prevalences of 47.0%, 18.8%, and 17.2% were obtained for Ascaris lumbricoides, Trichuris trichiura, and hookworm infections, respectively. The number of...

Epidermal parasitic skin diseases (EPSD) are a heterogeneous category of infectious diseases in which parasite-host interactions are confined to the upper layer of the skin. The six major EPSD are scabies, pediculosis (capitis, corporis and pubis), tungiasis and hookworm-related cutaneous larva migrans. We summarize the current knowledge on EPSD and show that these diseases are widespread, poly...

The mechanism by which small animals such as rodents resist or eliminate nematode parasites requires mucosal inflammation as the final effector of the immune response. The resulting freedom from chronic infection may be worth the price of short-term illness. Putative vaccines which attempt to enhance the natural effect will have to take into account the inflammatory cost to the host. Human helm...

OBJECTIVE To determine the efficacy of single doses of albendazole, ivermectin and diethylcarbamazine, and of the combinations albendazole + ivermectin and albendazole + diethylcarbamazine against common intestinal helminthiases caused by Ascaris and Trichuris spp. METHODS In a randomized, placebo-controlled trial, infected children were randomly assigned to treatment with albendazole + place...

This study aims to determine the prevalence of protein-energy malnutrition and its association with soil-transmitted helminthiases in Orang Asli (Aborigine) children in Selangor, Malaysia. The results obtained from 368 children aged 2-15 years showed that the overall prevalence of mild and significant underweight was 32.1% and 56.5% respectively. The prevalence of mild stunting was 25.6% while ...

OBJECTIVES To evaluate the effect of ivermectin mass drug administration on strongyloidiasis and other soil transmitted helminthiases. METHODS We conducted a retrospective analysis of data collected in Esmeraldas (Ecuador) during surveys conducted in areas where ivermectin was annually administered to the entire population for the control of onchocerciasis. Data from 5 surveys, conducted betw...
