Altered serum inhibin b levels in adolescents with varicocele.

Background/purpose: Different studies have evaluated testicular hormonal dysfunction in adolescent varicocele but with variable results. Recently, inhibin B has been proposed as a marker for spermatogenesis and Sertoli cell function. The aim of the present study was to study in a homogeneous cohort of adolescents inhibin B and other hormones to detect whether untreated varicocele may be associated with any modifications of these factors.

Scintigraphic evaluation of colonic motility in patients with anorectal malformations and constipation.

Background And Purpose: Constipation is one of the major sequelae in patients after correction of anorectal anomalies (ARAs). The aim of the present work has been to assess the colonic transit time, using radioisotope scintigraphy, in patients operated for ARA and experiencing constipation in the follow-up. The results were compared with transit time from children with true functional constipation.
