Update on Multicystic Dysplastic Kidney.

Multicystic dysplastic kidney (MCDK) is the most common cause of cystic disease in children. It is characterized by multiple non-communicating cysts of varying sizes with no identifiable normal renal parenchyma. The incidence ranges from 1 in 1000 to 4300 live births, and it is one of the most commonly detected anomalies on prenatal ultrasound.

From childhood migraine headache to pheochromocytoma.

Pheochromocytoma may have multiple clinical manifestations including paroxysmal hypertension, tachycardia, sweating, nausea, and headache (Phillips et al., 2002). Migraine has some of the manifestations seen with pheochromocytoma.

Mismatch in breast and detector size during screening and diagnostic mammography results in increased patient radiation dose.

Rationale And Objectives: When using mammographic detectors of different sizes, it can be difficult to match patient breast size to optimal detector size. We studied whether a mismatch between breast size and optimal detector size resulted in increased radiation exposure.

Materials And Methods: All screening and diagnostic (Dx) mammography patients during a 6-week period in November-December 2009 (864 patients) were evaluated (institutional review board exemption for quality assurance studies).

Robotically assisted excision of ovarian vein for intermittent ureteral obstruction.

With the increasing popularity of robotically assisted procedures, new indications for robotically assisted surgery are being examined. Although open and laparoscopic surgical management of intermittent ureteral obstruction from ovarian vein syndrome has been reported previously, we report the first use of robotic assistance for ureterolysis and ovarian vein excision.

Orchiopexy practice patterns in New York State from 1984 to 2002.

Purpose: Cryptorchidism is the most common genital anomaly identified at birth, and endocrine disrupters in the environment may be causing an increase in this entity. To determine whether the rate of surgery for undescended testes is increasing, we evaluated all documented orchiopexies performed in New York State during a 19-year period.

Materials And Methods: We used the New York State Statewide Planning and Research Cooperative System database to identify all orchiopexies performed between 1984 and 2002.

Regional differences in responses of rabbit detrusor to electrical and adrenergic stimulation: influence of outlet obstruction.

Objective: To examine regional responses of control and obstructed rabbit detrusor strips to electrical and adrenergic stimulation, and determine whether outlet obstruction causes regional variations in blood flow throughout the detrusor, as the detrusor smooth muscle of the bladder body has previously been considered homogeneous in its pharmacological properties.

Materials And Methods: Fourteen male rabbits had the bladder outlet surgically obstructed for 2 weeks and were compared with 10 unoperated control rabbits. Blood flow was measured with the bladder empty and at capacity, using fluorescent microspheres.
