Anchylorhynchus vanini sp. nov. from the Amazon is described, including the mouthparts and male genitalia. The new species is compared with similar species within the genus and the key to the species of Anchylorhynchus provided by Vaurie (1954) is modified to include the new species. Adult specimens were collected in flowers of the palm Syagrus vermicularis Noblick and additional collections in...

The present study was performed to determine the prevalence of Enterobius vermicularis among preschool children in Gimhae-si, Korea. A total of 6,921 preschool children in 76 kindergartens were examined using the cellotape perianal swab method. The overall egg positive rate (EPR) was 10.5%. The EPR in boys was higher than that in girls (adjusted odds ratio [AOR]: 1.5, P<0.001), and it was highe...

Enterobius vermicularis (pinworm) is the only nematode that infects humans. It is one of the most common intestinal parasites. Pinworm commonly infests the terminal ileum and colon, and does not cause severe morbidity unless ectopic infection occurs. However, granulomatous lesions caused by ectopic Enterobius vermicularis infection may lead to unusual clinical symptoms and may be misinterpreted...

The objective of this study was to describe the occurrence of intestinal parasites inside public restrooms and buses from a Brazilian city. Sample material was obtained using a transparent adhesive tape. Thirty two public restrooms were investigated and two (6.25%) were contaminated with helminth eggs (Ascaris lumbricoides and Enterobius vermicularis). Of the sixteen different bus lines, three ...

A cross sectional survey of Enterobius vermicularis was carried out in 808 children in the Bangkok metropolis and nearby provinces.

Background: Early diagnosis of appendicitis is important during pregnancy.  Unlike omentom, cecum and appendix are not likely to be displaced by the growing uterus, so the concept of position change of the appendix during pregnancy is questionable. Objective: To determine the anatomical location of appendix during pregnancy. Methods: In a prospective study from October 1995 to March 1999, 291 w...

Background: The appendix is considered as part of the gut-associated lymphoid tissue; however, lymphocyte subsets in this tissue are not fully defined. Objective: To investigate and compare the function and phenotype of lymphocyte subsets in peripheral blood and appendix of patients with normal and inflamed appendix tissues. Methods: Peripheral blood samples and appendiceal mononuclear cells we...

Enterobius vermicularis has the widest geographic distribution among parasitic worms. This infestation is more common children in population centers (nursery school, preschool).
