Cimetidine and coumarin therapy of renal cell carcinoma. A pilot study.

Thirty-eight patients with metastatic renal-cell carcinoma (RCC) and 1 patient with a second primary RCC were treated with coumarin and cimetidine. Patients received 400 mg cimetidine p.o. daily and after 1 week 100 mg coumarin p.o. daily in addition until tumour progression. Two complete remission (30 and 50+ months) and 3 partial remissions (14, 13.8 months) could be achieved. Problems regarding possibly spontaneous regressions and comparable results of other treatment in RCC are discussed.

[Multicystic renal oncocytoma].

The cystic variant of renal oncocytoma was defined by Ogden et al. (1986), who described a single case. A further case is described in the present communication, with notes on the clinical presentation, aspiration cytology, and histology of the surgical specimen. Follow-up over 3 years has been uneventful.

Diagnosis of Chlamydia trachomatis infection--culture versus serology.

The diagnostic value of different laboratory methods in detecting Chlamydia trachomatis infections in high risk groups was analysed. The efficiency of a direct specimen test was compared with serology (IgG and IgM ELISA) and culture in L929 cells, stained either with fluorescein conjugated monoclonal antibodies or with iodine. Patients (no. = 1041) with localized genital infections attending a STD clinic, sexual contacts and patients with ascending infections from urological and gynecological clinics were examined. Chlamydia trachomatis was detected in 225 patients: 210 (93.3%) were reactive in the direct test (smears stained with monoclonal antibodies), whereas culture missed only 5 (sensitivity 97.8%) when stained by the same method. Cultures stained with iodine produced the lowest recovery rate (73.8%), but this rate increased to 80.9% when a second passage was performed. In addition the prevalence of Neisseria gonorrhoeae, Mycoplasma hominis, Ureaplasma urealyticum, Candida albicans and Trichomonas vaginalis was investigated. In patients with non-gonococcal urethritis (no. = 331) and cervicitis (no. = 353), Chlamydia trachomatis was isolated in 32.3% and 12.8% respectively. However, this pathogen could be isolated in only 3 (15.8%) out of 19 patients with epididymitis and 15 (14%) out of 107 patients with adnexitis, although 66.7% and 93.3% respectively had specific IgG antibodies. Specific IgM could by detected with a sandwich ELISA in patients with adnexitis (46.7%), epididymitis (33.3%), cervicitis (22.2%), non-gonococcal urethritis (14%) and in the sexual partners of patients with genital infections (35.7%). The direct specimen test with monoclonal antibodies is the method of choice for the diagnosis of a C. trachomatis infection in patients with urethritis and cervicitis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Extracorporeal shockwave lithotripsy in sedation-analgesia].

The aim of the present study was to examine the effects of combined sedation and analgesia during extracorporeal shockwave lithotripsy using the Dornier lithotriptor HM III. We used a combination of a benzodiazepin derivatives with an opioid. We tested the dosage of drugs needed in relation to the length of treatment, the size of the stone and the overall energy output of the lithotriptor. In addition, continuous records were made of the patient's blood pressure and the oxygen saturation in the blood, with and without oxygen insufflation. Our results show that sedation combined with analgesia is a reasonable and useable alternative to general or regional anaesthesia for extracorporeal lithotripsy.

On the therapy of induratio penis plastica (Peyronies disease) by means of radium moulages.

In the past 50 years 2210 patients suffering from induratio penis plastica were admitted to our department. In 69% of the cases an improvement could be observed within 18 months after radium moulage therapy. By improving radium protection the therapy may now be performed without any significant exposure of the testes. A 15 year old patient is the youngest case reported in world literature. Trend analyses show a case shift towards the senium.

[Modification of suprapubic prostatectomy using a biological gluing technic].

Fibrinogen cryoprecipitate, thrombin solution and factor XIII concentrate were used for gluing in suprapubic transvesical prostatectomy. The fibrin glue was applied to an absorbable collagen velour placed in the prostatic bed. Postoperative blood loss was significantly smaller than in a control group. The gluing technique resulted in a sparing of the number of blood transfusions, a reduction in disturbances of wound healing and a shortening of postoperative hospital stay. Negative consequences of this gluing technique have not so far been observed.

A histochemical study of glycosidases in benign prostatic hyperplasia and in prostatic carcinoma in the human.

In benign hyperplasia marked beta-glucuronidase and N-acetyl-beta-glucosaminidase activity was seen in the prostatic epithelium whereas the reactions for 5 other glycosidases were only slight or negative. The intensity of the reaction for the glycosidases in prostatic carcinoma was dependent upon the degree of the differentiation. The possible importance of glycosidases for the invasiveness of prostatic carcinoma is briefly discussed.
