The role of diet in prostate cancer.

This is a one-to-one, age- and race-matched case-control study involving 55 histologically confirmed black prostate cancer patients and 55 controls who were seen at three major hospitals in Washington, DC from 1982 to 1984. Personal interviews were conducted to obtain the number of times food items of specified serving size were consumed per week by cases and controls; the subjects were grouped according to the age periods 30-49 and 50 years and older. We then calculated the average daily consumption of each of 18 nutrients per 1,000 calories. There was a significant negative association between linoleic acid (p less than 0.04) for the 50 years and older group, thiamin (p less than 0.05) for those 30-49 years old, riboflavin (p less than 0.03) for the 50 and older group, and iron (p less than 0.05) for those 30-49 years old. The results of this study suggest that the intake of thiamin and iron (in subjects 30-49 years old), linoleic acid and riboflavin (in subjects 50 years and over) could be protective because control subjects consumed more of these nutrients than did the cases.

Blue nevus of the prostate: ultrastructural study

A case of blue nevus of the prostate in a sixty-five-year-old black patient was studied by light and electron microscopy. In the melanocytes only fully melanized melanosomes were present; melanosomes in early stages of development were entirely absent. It was concluded that the formation of melanosomes within the melanocytes in blue nevus of the prostate is probably under genetic control.

Penile Prosthesis in the Management of Priapism

Priapism is the abnormal persistence of erection, painful and not sexually induced. Many cases resolve spontaneously, but if it persists for a long time there is anoxic injury and fibrosis of the corporal tissues and the sequelae is impotence. The main problem with priapism is pain and the probability of a resultant impotence. We have managed 2 patients with recurrent priapism with insertion of penile prosthesis with satisfactory results.

Mixed mesodermal tumor of urinary bladder: A Light and Electron Microscopic Study☆

Light and ultrastructural findings in a mixed mesodermal tumor of the urinary bladder are reported. The mesenchymal component of the tumor contained undifferentiated mesenchymal cells and cells with chondroblastic differentiation. The neoplastic chondrocytes displayed an abundance of cytoplasmic microfilaments and had a scalloped cell surface.

Prostate Fossa Packing: A Simple, Quick and Effective Method of Achieving Hemostasis in Suprapubic Prostatectomy

Introduction: Suprapubic prostatectomy remains a very common surgical treatment for bladder outlet obstruction from an enlarged prostate in the developing world. It is a technically simple procedure which can be learned by nonurologists who perform the bulk of these procedures in the developing world. Intraoperative and postoperative bleeding, however, can be a problem. We describe our experience with prostatic fossa packing at the time of the procedure, as a very simple, quick and effective technique for maximal hemostasis. Material and Methods: We have used this technique for several years at our institution and the results have been excellent. However, the major advantages of this technique became highlighted when the primary author visited Eritrea on a medical mission trip and used it in 42 consecutive cases. We looked at the hemorrhagic complications, both intraoperatively and postoperatively, infections and other complications related to the technique. Results: The 42 patients were typical of the patients that are seen in the developing world for suprapubic prostatectomy. The age range was 49–102 years. 75% had indwelling urethral catheters secondary to urinary retention. The duration of the catheters was from 2 weeks to 10 months. All the patients who had the indwelling catheters had bacteriuria. 56% had associated bladder calculi and 25% had associated inguinal hernias. The average surgical time was 45 min. The average intraoperative blood loss was estimated at 160 ml. There were no blood transfusions. There were no infections and there were no complications related to the packing. Conclusion: Packing of the prostatic fossa at the time of enucleation of the adenoma is a very simple, quick and effective way to achieve hemostasis in suprapubic prostatectomy. It is also very easy to learn. With this technique we have achieved zero rate of transfusion and no infections. The surgical time is also reduced. We have had no morbidities associated with this technique and highly recommend it.

Gonadal stromal tumor in black male

A twenty-five-year-old black male presented with a right testicular mass which had progressively increased in size over three years. He was in good health and noted no other general abnormalities. Taking all malignant precautions, excisional biopsy of the lesion revealed gonadal stromal tumor by frozen section. The testis was left in situ, and the patient has continued to remain asymptomatic.
