Histological examination of solitary contralateral descended testis in congenital absence of testis.

Purpose: Congenital absence of the testis is believed to be secondary to prenatal torsion, differing from the isolated undescended testis. We determined whether congenital absence of the testis is associated with abnormal histology in the solitary contralateral descended testis.

Materials And Methods: A total of 239 boys with a primary diagnosis of unilateral absent testis underwent orchiectomy and testis biopsy.

Funding source and conflict of interest disclosures by authors and editors in gastroenterology specialty journals.

Introduction: Declarations of conflicts of interest have received considerable scrutiny in recent years.

Aim: To determine if the leading gastroenterology journals had a formal conflict of interest disclosure policy and the extent to which this policy was followed by reporting of funding sources and potential conflicts of interests of the authors and editors of published studies.

Methods: We examined original articles and editorials in 12 leading journals (determined by impact factor) devoted to gastroenterology and hepatology.
