A Review on Parasitological, Immunological and Molecular Methods for ‎Diagnosis of Human Strongyloidiasis

Strongyloidiasis caused by intestinal nematode Strongyloides stercoralis may leads to hyperinfection syndrome and disseminated infections. If not diagnosed and treated properly, it may even end to the death of patients. Sensitivity of parasitological methods is not good enough and multiple stool sampling over consecutive days is essential to improve the detection rate. The agar plate culture me...

Unexplained polyposis: a challenge for geneticists, pathologists and gastroenterologists.

Two main colorectal polyposis syndromes have been described, familial adenomatous polyposis and MUTYH-associated polyposis syndromes. Some polyposis remains unexplained: 20% of adenomatous polyposis and serrated polyposis. The aim of this study was to evaluate in a cohort of patients with unexplained polyposis whether a genetic defect could be detected. Individuals presenting polyposis with mor...

A simple answer for a splicing conundrum.

T he medieval philosopher William of Occam admonished that it is best to minimize the postulated entities needed to explain a system. This concept of choosing the simplest explanation of unknown phenomena is now known as the principle of parsimony or Occam’s razor. However, in biology, where systems tend to evolve toward states of greater complexity, Occam’s razor can be a dangerous tool. Most ...

Small-bowel radiology – an introduction for gastroenterologists

The field of radiological small-bowel imaging is changing rapidly, as is small-bowel enteroscopy. New techniques allow the depiction of intraluminal, mural, and extraintestinal features of various small-bowel disorders, such as Crohn's disease, small-bowel polyposis syndromes, small-intestinal malignancies, and coeliac disease. For patients in need of repeated small-bowel imaging, modalities th...
