Seminal vesicle cyst associated with ipsilateral renal agenesis.

Seminal vesicle cysts present at the age of high sexual activity. They manifest with symptoms of bladder irritation and pain on ejaculation. They arise because of congenital obstruction of ejaculatory duct. Diagnosis can be made by careful rectal examination supplemented by an intravenous urogram, cystogram, seminal vesiculogram, and cystourethroscopy. Surgical excision of the cyst is the definitive treatment. We present a case of right seminal vesicle cyst associated with ipsilateral renal agenesis, with a review of the pertinent literature.

Validity of fecal coliforms, total coliforms, and fecal streptococci as indicators of viruses in chlorinated primary sewage effluents.

Quantities of combined chlorine that usually destroyed more than 99.999% of the indigenous fecal coliforms, total coliforms, and fecal streptococci in primary sewage effluents destroyed only 85 to 99% of the indigenous viruses present. Viruses were recovered from five of eight chlorinated primary effluents from which fecal coliforms were not recovered by standard most-probable-number procedures. The limited volumes of such chlorinated effluents that can be tested for indicator bacteria with currently available multiple-tube and membrane filter techniques restrict the value of fecal coliforms, fecal streptococci, and even total coliforms as indicators of viruses in these effluents. Although fecal coliforms and fecal streptococci are useful indicators of viruses in effluents from which these bacteria are recovered, the absence of these bacteria and even total coliforms from disinfected effluents (in standard tests) does not assure that viruses are also absent.

CAP, HCS and urinary oestriol assays in diabetic pregnancy.

The value of serial estimations of plasma CAP, HCS and urinary oestriol assays in pregnancies complicated with diabetes has been studied. The material consists of 31 patients, 16 of whom delivered normal infants and 15 delivered newborns with diabetic foetopathy. It is concluded that the levels of CAP, HCS and urinary oesteriol excretion in diabetic pregnancies are comparable to those found in normal pregnancy. No significant differences in the biochemical parameters were detected between diabetic women who delivered infants with foetopathy compared to diabetic women who delivered normal infants. The maternal oestriol excretion was, however, somewhat higher in diabetic women who delivered infants with macrosomia.

[Dosage of calcium and phosphate in parenteral feeding].

In a carbohydrate combination solution containing 12.5 mEq/1 calcium and 12 mmol/1 phosphate the concentrations of calcium and phosphate were kept constant during parenteral infusion therapy with carbohydrate, at a rate of 0.5 g/kg/h and amino acids at a rate of 0.1 g/kg/h. Balance for calcium and phosphate was positive. Calcium excretion was slightly above the levels determined in oral nutrition. A slight modification of calcium supplement by changing the concentration of the solution to 10 mEq/1 is suggested.

[Water and mineral balance in refeeding after total fasting].

The water balance and the electrolyte balance were measured in 6 patients after 14 days of total starvation. After fasting a 600 calorie formula diet was given for the whole period. The potassium balance was +32 mval/day and that of sodium +120 mval/day. The total loss of potassium in 14 days was 488 mval and that of sodium only 126 mval. Sodium loss is replaced within one day of refeeding. No replacement of the potassium loss was noticed during the 4 day treatment.

[Nutrition after gastrectomy].

Dietary therapy after gastrectomy demands a differentiated approach. In the immediate postoperative phase parenteral nutrition is indicated. If no complications occur, the transition to oral nutrition can soon be made, the basic principle of which is adherence to 6-8 small meals. Since, in our experience, after gastric resections numerous disorders can occur, a carefully controlled diet with the aid of nutrional anamnesis is to be recommended. At the same time substitution of vitamin B12, iron, calcium and pancreatic enzymes is absolutely essential.

[Treatment of hyperuricemia using daily doses of 50 and 25mg of benzbromarone].

By treating 16 hyperuricemic patients each with 25 and 50 mg of Benzbromarone a significant decrease of the uric acid concentration in the serum into the normal range is achieved. On the 5th and 6th day after beginning the treatment the dosage of 25 mg of Benzbromarone renders a morning value of 5,3 +/- 1,0 and an evening value of 5,0 +/- 0,9 mg/100 ml. After administration of 50 mg of Benzbromarone there is also prevailing a steady-state behaviour on the 5th and 6th day for the uric acid concentration in the serum. Thereby the morning value is 3,7 +/- 0,8 mg/100 ml and th evening value 3,4 +/- 0,9 mg/100 ml. After both dosages an increased urate elimination occurs initially during the 1st, 2nd and 3rd day after beginning of the therapy. However, after having achieved therapeutically reduced uric acid levels, the uric acid elimination from the 4th, 5th and 6th day partially ranges below those values existing before beginning of the therapy. During a chronic treatment no hyperuraturia can be observed on account of the therapeutically reduced serum concentrations. Consequently an increased risk towards a formation of urate calculi is not given under the long-term treatment.

[Effect of benzbromarone in 100mg and 50mg doses on healthy subjects].

After oral application of 100mg of Benzbromarone a significant decrease of the uric acid concentration in the serum up to the 14th day after beginning of the treatment to a mean value of 1,7 mg/100 ml is achieved; while the application of 50 mg of Benzbromarone reduces the uric acid concentration only to a value of 3,4 mg/100 ml. Thereby the differences amounts to about 1,7 mg/100 ml. The urate elimination increases after 100 as well as after 50 mg of Benzbromarone. Only initially an increased uric acid elimination could be observed. In the further course the uric acid elimination remains increased despite reduced serum concentrations.

[Alterations of cerebrospinal fluid pressure in experimental communicating hydrocephalus. Response of CSF-pressure to increased CO2-tension (author's transl)].

The response of cerebrospinal fluid pressure to increased arterial carbon dioxide tension was examined in 5 control dogs and 7 dogs with experimental communicating hydrocephalus. The cerebrospinal fluid pressure in control animals only rose to 35 mm Hg after elevation of the arterial CO2 tension. In dogs with experimental communicating hydrocephalus, however, a significant rise of intracranial pressure to 60 mm Hg can be demonstrated. This is accompained by a marked simultaneous decrease of cerebral perfusion pressure in hydrocephalic animals. Progression of communicating hydrocephalus can be explained as damage to the cerebral tissue by increased intracranial pressure waves and by ischemia due to low cerebral perfusion pressure.

Hypertension in radiation nephritis. Report of a patient with unilateral disease, elevated renin activity levels, and reversal after unilateral nephrectomy.

A patient received intensive radiation to the right renal area for abdominal Hodgkin's disease and approximately ten years later severe hypertension developed. The presence of radiation nephritis with a severely shrunken right kidney was demonstrated and this was accompanied by a substantial increase in renin activity from the right kidney. Treatment with propranolol hydrochloride temporarily lowered the blood pressure and peripheral renin activity levels. Subsequent right nephrectomy resulted in a decrease in renin activity and a reversal of the hypertension. The data implicate a renin angiotensin mechanism as probable cause of hypertension in radiation nephritis.

[Potassium substitution in fasting].

Twenty patients, divided in two groups to ten were undergoing a fasting period for 14 days. One group received 80 mEq potassium per day. Despite of identical loss of body-weight, the application of potassium showed the following advantages: 1) The body is able to keep acid-base-balance. 2) The important loss of potassium, induced by starvation can be reduced to a minimum.
