[Diagnosis and therapy of malignant testicular neoplasms].

For successful treatment of even advanced testicular tumors an accurate histological classification and clinical staging is necessary. The pathohistomorphological classification can be completed by the so-called tumor markers such as alpha-fetoprotein and beta-humanchoriongonadotropin (beta-HCG). These markers are especially valuable in the follow-up of the patient and in the control of the therapeutical effectivity. By optimal diagnosis and therapy seminomas in stage I and II are in 70% to 100%, teratomas in 40% to 80% curable; in the more advanced stages in 30 to 40% a two years relapse-free time can be obtained.

Congenital intracardiac band: a rare cause of nonrheumatic combined aortic and mitral regurgitation.

A patient had a congenital intracardiac band lying across the aortic valve that caused combined aortic and mitral valvular regurgitation. The band was excised, and the damaged aortic valve was replaced with a prosthesis. The case illustrates that not all congenital intracardiac bands are completely asymptomatic and not all bivalvular incompetence is rheumatic in origin.
