Nonbacterial prostatitis is a common clinical entity which is often difficult to diagnose and treat. Little is known with regard to the etiology and pathogenesis of this disease process. To develop an animal model and characterize the immune parameters of nonbacterial prostatitis, we harvested the prostates from SJL, AJ, Balb/c, C57bl/6 and C57bl/6 lpr mice. ⋯ Adoptive transfer studies demonstrated the prostatic inflammation to be at least in part immune mediated. We conclude that injection of syngenic prostate antigen induces prostatic inflammation similar to clinical nonbacterial prostatitis. Nonbacterial prostatitis may be an autoimmune process.

Comparative StudyThe management of patients with nonseminomatous germ cell tumors of the testis with serologic disease only after orchiectomy.
Management of patients with nonseminomatous germ cell tumors of the testis who have persistently elevated serum tumor marker levels (alpha-fetoprotein and/or human chorionic gonadotropin) following orchiectomy and no clinical evidence of disease is controversial. We reviewed our experience with 15 such patients at our cancer center between March 1977 and November 1991. ⋯ All group 1 patients required subsequent chemotherapy for retroperitoneal disease or persistent marker elevation, whereas only 1 of the 4 who received primary chemotherapy required later surgery. We conclude that tumor marker elevation in this setting is usually indicative of systemic tumor, which is best treated primarily by initial chemotherapy.
