Subjective and objective analysis of the prevalence of Peyronie's disease in a population of men presenting for prostate cancer screening.

Purpose: In this study we defined the prevalence of Peyronie's disease in a cohort of men being screened for prostate cancer in the United States. The association between Peyronie's disease, and medical comorbidities and patient self-reported erectile dysfunction was also defined.

Materials And Methods: A total of 534 men presenting to 1 of 3 prostate cancer screening centers provided a complete medical history, underwent physical examination performed in all by a urologist and completed the Sexual Health Inventory for Men (SHIM) questionnaire.

Bone mineral density among cirrhotic patients awaiting liver transplantation.

Osteoporosis is an important and common complication in patients with chronic liver disease.

BMD of the lumbar vertebrae (L) and femoral neck (F) were obtained in 104 consecutive cirrhotic patients.

Analysis of c-kit protein expression in small-cell lung carcinoma and its implication for prognosis.

Recently, therapies targeting signaling pathways involved in the pathogenesis of different tumors have been developed. Studies have shown that the tyrosine kinase inhibitor STI-571 (Gleevec) is used successfully against tumors expressing the c-kit oncogene, such as gastrointestinal stromal tumors (GISTs). A recent in vitro study also demonstrated an antiproliferative effect of STI-571 on small-cell lung cancer (SCLC) cell lines.
