Identification of platinum and palladium particles emitted from vehicles and dispersed into the surface environment.

Platinum, palladium, and rhodium are emitted from vehicle catalytic converters. Until now, the form of precious metal particles in road dust and urban waste has not been identified. This study has located, imaged, and analyzed these particles in road dust and gully waste.

200 consecutive hand assisted laparoscopic donor nephrectomies: evolution of operative technique and outcomes.

Purpose: Despite the popularity of hand assisted laparoscopic donor nephrectomy published experience is less than that with standard laparoscopic donor nephrectomy and few critical assessments of operative maneuvers have been described.

Materials And Methods: We describe the impact of changes in operative technique made by a single surgeon during 200 hand assisted laparoscopic donor nephrectomies.

Results: With a mean operative time of 229 minutes and hospital stay of 1.

Benign paratesticular Schwannoma.

Scrotal masses are common findings on genitourinary exam. The majority of these masses are benign and can be identified via history and physical exam alone. Question as to the origin of these masses merits additional evaluation that typically consists of an imaging study (e.

Penile torsion repair using dorsal dartos flap rotation.

Purpose: Counterclockwise penile torsion is a frequently noted congenital deformity. Previously proposed techniques of torsion repair are ineffective or pose significant operative risks. We introduce a novel technique using dorsal dartos flap rotation.

Inguinal bladder hernia masking bowel ischemia.

Displacement of the bladder outside of the pelvis by way of the inguinal canal represents an infrequent presentation of an inguinal hernia that rarely causes urinary tract obstruction. However, bladder hernias can become bothersome, painful, and potentially dangerous. We report a 56-year-old man with a chronic bladder hernia who became acutely unable to empty his bladder from its position in the right hemiscrotum after a motor vehicle accident.
