[The potentiation of betazol stimulated gastric acidity by prednisolone in dogs (author's transl)].

In a total of 46 dogs divided into 5 groups the acute effect of a high dose of prednisolone (40 mg/kg i.v.) on betazol stimulated gastric seccretion (5mg/kh s.c.) was investigated. There was no effect of prednisolone alone. The combination of betazol and prednisolone showed a significant potentiation of betazol stimulation. This effect was not seen after truncal vagotomy before stimulation. The mechanism is either cholinergic or an interaction in the metabolism of histamine.

[Antibacterial therapy of urinary tract infections. Results of a clinical trial with the combination sulfamoxol/Trimethoprim (= CN 3123) (author's transl)].

In the present paper, the use of the combination preparation sulfamoxol/trimethoprim (CN 3123, Nevin [Grünenthal], Supristol [Nordmark]) in urinary tract infections is reported. This preparation was used in 165 patients of both sexes and all ages. The initial dose was 2 tablets followed by a maintenance dose of 1 tablet every 12 hours for a treatment lasting 10 days on the average. The preparation led to asepsis in 69% of the patients with chronic urinary tract infections if the organisms were sensitive in vitro. In asymptomatical urinary tract infections complicated by fistula and transurethral indwelling catheters, on the other hand, elimination of organisms was only attained in 46%. In our opinion, antibiotic therapy is not indicated in these patients only after taking off the indwelling catheter.

[Germinal testicular tumors].

Characteristic for the germinal cell tumors of the testis is their great variety. Collins and Pugh gave a classification of testis tumors under consideration of the genesis of the tumor and the clinical progressing. The staging should be done according to the TNM-system which is based on the UICC recommendations of 1973. If a tumor is suspected an exploration of the testis must be performed. After definitive histological diagnosis via immediate section for microscopic examination during surgery an enlarged orchiectomy and local lymph node dissection has to be performed. In cases of seminoma a 5-year-survival-rate of 90 to 97 per cent can be achieved by radiation of two fields (4 fields in case metastases are suspected). Because of the radio resistance of the teratoid tumors a retroperitoneal lymph node dissection has to follow the enlarged orchiectomy. With a subtile operating technique all the lymph nodes between diaphragm and aortic bifuraction can be removed in case of operability. Postoperative radiation therapy is only recommended in case of excessive lymph node metastases. By an adjuvant chemotherapy following retroperitoneal lymph node dissection a 5-year-survival-rate of more than 80 per cent can be obtained in cases of teratoid tumors.

[Indanyl Carbenicillin in the treatment of urinary tract infections due to difficult urological organisms (author's transl)].

Fifty in-patients suffering from chronic urinary tract infections with underlying urological diseases received the oral Carbenicillin preparation Indanyl Carbenicillin (short term Carindacillin) for 10 days in a dosage of 1 g q.i.d. The therapy results were objectified by blood and urine tests performed prior to and after treatment. Indanyl Carbenicillin led to a sterile urine in nearly 60% of the patients; in about 85% of the cases the primary organism was eliminated. The drug was particularly active against difficult organisms such as Proteus, Klebsiella and Pseudomonas. The results obtained in this study are somewhat surprising as the dosage used produces bactericidal levels of the active substance only in the cavity system of the efferent urinary tract but not in the tissue. No effect on blood picture or liver function was observed. Side effects occurred in 8 patients, they disappeared with continued therapy or after discontinuation of the drug. Considering the good efficacy observed in this study and because of the possibility of oral administration, Indanyl Carbenicillin appears to be suitable also for out-patient treatment of chronic urinary tract infections due to difficult urological germs.

Possible pharmacological means of treating renal colic.

The effects of various drugs on the partially obstructed ureter were investigated in a new model experiment which permitted the calculation of peripheral resistance. After the administration of noradrenaline, the local spasm of the ureter in the region of the obstruction was increased and the urinary flow fell. After administration of the alpha-blocker phentolamine and of the beta-receptor stimulant orciprenaline there was a reduction of the peripheral resistance and an increase in urinary flow due to spasmolysis. Because of its lower side-effect rate, phentolamine is worth investigating in further clinical studies.

[Late results of nephropexy for nephroptosis according to a new indication schema].

A new schema for indicating operative treatment of nephroptosis is suggested. It was validated by an analysis of late results of 37 patients: 32 were completely free of symptoms, three still had the same symptoms but previously present pyelonephritis had healed. Two patients without long-term antibiotic treatment still had complaints and positive bacteriological findings. Non of the patients had haematuria. In two hypertensives the blood pressure had become normal.

[Early and late results after cryosurgical treatment of bladder neck obstructions (author's transl)].

We report on late results of 100 risk patients, who were operated by cryosurgical technique because of bladder neck obstructions. Detailed representation of complications. The primary mortality was 5%. Controls after one year showed good functional results on 80% of the patients. 60% of the patients had sterile urine, whereas only 17% of the male patients had no infection before the operation. As to the anatomical results we could talk of a cryoprostatectomy in 25% of the cases. Because of a 20% failure cryosurgery remains a palliative operation, which can only be carried out on risk patients. Because of little hemorrhagic diathesis and the possibility to perform this operation under local anesthesia cryosurgical operations on the other hand are suitable for patients, who cannot be anesthetised. Otherwise these patients had needed a permanent catheter. We prefer shorter freezing times of 3--4 min. Essentially we could show the same functional results as other authors, who preferred longer freezing times, until they reached a certain temperature in the prostatic capsule. By shorter freezing times on the contrary we could avoid secondary transurethral resections of larger necroses. New disturbed micturition after cryosurgical treatment of the prostate is unusual. The question of a later recidivation is of secondary importance because of the primary high morbidity rate of the selected number of cases.
