Etiologic considerations in penoscrotal hypospadias repair.

Superficial location of fivrous bands causing chordee in patients with penoscrotal hypospadias has been demonstrated by microscopic and gross photographs. Our technique to manage this problem is similar to that described by Allen and Spence and by King for distal hypospadias and has been used in 120 patients. The technique involves the repair of the embryologic penile defect by advancing the closure of the urethral groove and transposing the scrotum to its appropriate caudal position. The repair is applicable in patients with failure of fusion rather than failure of the development of the urethral groove as in perineal hypospadias.

A renal cause for massive retroperitoneal hemorrhage--renal angiomyolipoma.

In any case of intra-abdominal trauma or hemorrhage a preoperative IVP is essential to determine the renal status. Preoperative catheter occlusion of the renal artery in these vascular tumors may be attempted to decrease blood loss. Stigmas of tuberous sclerosis should be sought in patients with vascular renal tumors, especially if they are bilateral. Conservation of renal tissue in tuberous sclerotic patients harboring renal angiomyolipomas is important.

Isolated ureteral injury secondary to transperitoneal stab wound.

The patient reported suffered a transperitoneal stab wound resulting in the isolated complete transection of the left upper ureter. In spite of immediate exploratory laparotomy, the time of recognition of the injury was delayed. The treatment consisted of an ellipitcal spatulated everting uretero-ureterostomy with interrupted fine chromic catgut over a stenting ureteral catheter. The postoperative course was smooth and the final result excellent. The importance of intravenous urography in penetrating abdominal or flank trauma cannot be overemphasized. This is the first reported case of isolated ureteral injury secondary to transperitoneal stab wound.

Staged treatment of invasive carcinoma of bladder.

A three-stage approach to carcinoma of the bladder consists of preliminary urinary diversion, radiation therapy, and simple total cystectomy. We have used this method for more than ten years. The survival rates are the same as generally published, and the morbidity and mortality contrast favorably with other reports. To date no patient has died within two months of completion of the course of therapy.

Ileal conduit urinary diversion in children.

In the evaluation of the morbidity associated with ileal conduit urinary diversion in children, a retrospective analysis of the complications in 125 such children was done. When retroperitoneal Penrose drainage was used or when additional surgical procedures were performed, a significantly increased number of early postoperative complications were found. Conversely, when peristomal skin preconditioning was accomplished or when a single layer ureteroileal anastomosis was constructed, postoperative morbidity was markedly reduced. Ileal conduit urinary diversion remains the most satisfactory method of permanent urinary diversion in children.

Antibody responses of hens fed vitamin E and passively acquired antibodies of their chicks.

Antibody responses of hens and their progeny were studied in commercial broiler nuclear lines. Starting at 168 days of age, individually housed pullets from lines A and B were fed a 16% crude protein and 2752 kcal metabolizable energy/kg mash diet supplemented with either 10 or 300 IU/kg of vitamin E fed as dl-alpha-tocopherol acetate. Fifty-eight days later (226 days of age), 12 hens per line-vitamin E subclass were inoculated i.v. with 0.1 ml of a 2.5% suspension of sheep red blood cells (SRBC). Plasma antibody titers were measured 6, 20, 40, 54, 70, and 88 days after inoculation. Hens from both lines were artificially mated to males from line C, and progeny from eggs collected 9-15, 25-30, and 65-70 days after inoculation were tested for antibodies to SRBC. Hens were reinoculated i.v. with 0.1 ml of 0.25% SRBC 88 days after the first inoculation, and their antibody levels were measured 3, 6, and 20 days later. Eggs laid 10-13 days after reinoculation were incubated, and antibody titers of chicks were measured at hatch. Antibody response of hens to an initial inoculation of SRBC was line-diet-time after inoculation specific. In line A, titers were greater for hens fed the lower than the higher vitamin E diet, whereas diet had no effect on the antibody levels in line B. Line effects (A > B) were observed on days 6 and 20 after inoculation but not thereafter. After the second inoculation, dietary vitamin E level had no effect on antibody levels of hens within lines, whereas a between-line difference (A > B) was observed for the lower but not the higher level of dietary vitamin E. Although there was no difference between diets for antibody transferred to progeny by line B, there was a difference (lower > higher) for line A. After reinoculation of their dams, antibody titers of chicks from line A, but not line B, reached levels similar to those after the first inoculation. Antibody levels were higher for chicks at hatch than in 16-day embryos or 10 days posthatch. The results of this research suggest genetic variation in response to immune stimulation by dietary vitamin E.
