Incidence of positive pelvic lymph nodes in patients with prostate cancer, a prostate-specific antigen (PSA) level of < or =10 ng/mL and biopsy Gleason score of < or =6, and their influence on PSA progression-free survival after radical prostatectomy.

Objective: To investigate how many men with low-risk prostate cancer had positive lymph nodes detected by radio-guided surgery and whether they had a higher biochemical relapse rate after radical prostatectomy, because in such patients most urologists dispense with operative lymph node staging, as nomograms indicate only a low percentage of lymph node metastases.

Patients And Methods: The study included 474 men with a prostate-specific antigen (PSA) level of < or = 10 ng/mL, biopsy Gleason score of < or = 6 and positive biopsies in one (group 1, 315 men) or both lobes (group 2, 159 men); follow-up data were available in 357 men. Men with adjuvant radiation or hormone therapy before the occurrence of biochemical relapse were excluded.

Prostate cancer relapse after therapy with curative intention: a diagnostic and therapeutic dilemma.

Prostate cancer is the most common malignant disease and second in causes of cancer death among men in Western Europe and North America. Despite improved surgical and irradiation techniques tumor relapse after curatively intended therapy is not uncommon. Due to the difficulty in discriminating local and systemic progression, it is often difficult to decide what this means for the patient and what kind of second-line treatment has to be given.

Postpartum curettage in patients with HELLP-syndrome does not result in accelerated recovery.

Objective: Our purpose was to examine the impact of immediate postpartum curettage on the recovery of patients with HELLP-syndrome (hemolysis, elevated liver enzymes, and low platelets).

Subjects: Between January 1994 and July 1997 all patients who presented with HELLP-syndrome in our institution underwent immediate postpartum curettage (n=24). Their outcome was compared with the recovery of women with HELLP-syndrome who were delivered without postpartum curettage between 1987 and 1993 (n=20).

Activation of glomerular mesangial cells by the terminal membrane attack complex of complement.

Treatment of cultured renal glomerular mesangial cells (MC) with nonlytic concentrations of the purified components (C5b-9) of the terminal membrane attack complex (MAC) of complement induced significant functional alterations characteristic of cellular activation. C5b-9-treated MC released large quantities of primarily vasodilatory prostaglandins. In addition, the secretion of an MC-derived auto-growth factor (MC interleukin 1) was greatly enhanced.
