Bilateral testicular germ cell tumors. Report of nine cases and review of the literature.

In a series of 181 patients with testicular germ cell tumors, the phenomenon of bilateral involvement of the testicles was observed nine times (5%). Two patients evidenced a simultaneous bilateral tumor, and, in seven others, a second tumor occurred after an interval ranging between 8 months and 6 years and 11 months. The incidence, histologic findings, therapy, and prognosis of bilateral testicular tumors are discussed on the basis of a survey of the literature.

[Long-term results after kidney transplantation].

In this investigation, our own long-term results after kidney transplantation were compared with those in literature, and the influence of recent findings on the survival rate of patients and transplants was analyzed. In 217 kidney transplant patients, the 5 and 9-year-patient survival rate was calculated at 58% and 45% respectively. The 9-year-transplant function rate was 38%.

Cyproterone acetate, testosterone, LH, FSH, and prolactin levels in plasma after intramuscular application of cyproterone acetate in patients with prostatic cancer.

Five patients with prostatic carcinoma (stages T3N0M0) were injected intramuscularly with 300 mg of cyproterone acetate (CPA) (Androcur-Depot) at weekly intervals. The concentrations of CPA, testosterone, LH, FSH, and prolactin in plasma after the first, third, and fifth injection were measured by specific radioimmunoassays. After five injections of Androcur-Depot, CPA levels were slightly higher than in previous determinations, suggesting that a balance between active substance release from the depot and excretion could be achieved after eight to twelve injections, with only slightly higher levels of active substance attained.

[Autologous human skin flaps in partial replacement of bladder wall (author's transl)].

Untreated autologous compound skin (Rehn's skin flap) was used in three patients for partial replacement of the urinary bladder wall. The early postoperative results regarding the general tendency of the healing process, primary density, capacity, and functional voiding of the bladder correspond with an ideal replacement of the bladder wall. Observations of long-term controls will be reported later.
