The proliferation of prostatic epithelium in chronic prostatitis.

The labelling index in chronic nonspecific prostatitis ranges from 0.7-2.1%. This value is markedly higher than in nodular hyperplasia (0.4%) as well as in differentiated adenocarcinomas (0.6%). Increased labelling index could only be determined in glands adjacent to inflammatory foci. In recognition of these findings we believe that a correct evaluation of the cell proliferation in chronic prostatitis is only possible if each single cell can be evaluated, whether it is altered by inflammation or not. Therefore, solid tissue biopsies appear to be more suitable in autroadiographical studies than cytological material alone.

[Metastasising carcinoma of the renal pelvis after Thorotrast pyelography].

A carcinoma of the renal pelvis was diagnosed in a female patient 42 years after a retrograde Thorotrast pyelogram. The patient died as a result of the carcinoma at the age of 60. The literature is reviewed. As a result of this case, the need is stressed for early recognition of Thorotrast depositis in the kidney. In this case it was demonstrated by autoradiography. Appropriate treatment is discussed.

[Neurogenic gastric tumours. Schwannomas and neurofibromas (author's transl)].

The literature concerning the definition, frequency, development and morphology of neurogenic gastric tumours is reviewed. The clinical, radiological and histological findings in eleven cases seen by the authors are described. The radiological differential diagnosis and errors in diagnosis are discussed. The significance of tumour perforation in making a type diagnosis is pointed out. There are few angiographic reports available at present.
