Asynchronous Bilateral Ovarian Torsion: Three Cases, Three Lessons.

Background: Ovarian torsion (OT) is a serious condition, and delay in surgical intervention may result in loss of the ovary. Children and adolescents who have suffered from ovarian torsion may be at risk for asynchronous torsion of the contralateral ovary.

Study Objective: Three cases of asynchronous bilateral ovarian torsion were reported to analyse clinical history of three patients, to review the current literature, and to draw a conclusion for future treatment.

Facile synthesis of light harvesting semiconductor bismuth oxychloride nano photo-catalysts for efficient removal of hazardous organic pollutants.

In the present work, bismuth oxychloride nanoparticles-a light harvesting semiconductor photocatalyst-were synthesized by a facile hydrolysis route, with sodium bismuthate and hydroxylammonium chloride as the precursor materials. The as-synthesized semiconductor photocatalysts were characterized using X-ray diffraction analysis, Fourier transform infra-red spectroscopy, Raman spectroscopy, Field emission scanning electron microscopy, X-ray photoelectron spectroscopy and Photoluminescence spectroscopy techniques. The crystal structure, morphology, composition, and optical properties of these facile synthesized bismuth oxychloride nanoparticles (BiOCl NPs) were compared to those of traditional bismuth oxychloride.

Penile repair in patients with epispadias-exstrophy complex-can we prevent resultant hypospadias?

Purpose: Male genitalia reconstruction in patients with exstrophy-epispadias complex often leads to secondary hypospadias, thus requiring additional surgery and resulting in possible complications. We describe a technique of male epispadias repair to prevent resultant hypospadias.

Materials And Methods: The complete penile disassembly technique is modified by multiple Z-plasties, which enable creation of a funnel-like bladder neck and urethral plate lengthening.

Bladder injuries following inguinal canal surgery in infants.

Purpose: Surgery of the inguinal canal is very common in infancy. Occasionally, injury of the bladder may occur with severe consequences. The aim of this paper was to warn young surgeons of this serious complication.
