[131I] Hippuran renography in the detection of orthostatic hypertension.

Scintigrams in prone and standing positions were done in 11 hypertensive women. All had nephroptosis with ventral rotation. On the basis of the renograms, seven patients were identified as suffering from orthostatic hypertension. Nephropexy resulted in normalization of blood pressure in six of the seven patients and normalization of the renograms of all seven. We believe that sequence scintigrams in prone and standing positions offer a simple method of identifying patients with orthostatic hypertension.

[Immunologic studies for the diagnosis of chronic prostatitis].

A prospective study comparing the results of Antibody-Coating-Test (ABC) in semen and aspiration biopsy of the prostate with immunodiffusion of the former was carried out. In 143 patients with clinical signs of prostatitis only 98 showed a positive ABC in their ejaculates. IGA-specific ABC was positive in 75%, IGG-specific ABC in 48%, and IGM-specific ABC in 9.6% respectively. Specimens gained by aspiration biopsy of the prostate were also demonstrating positive ABC. Consistently negative was the ABC in 15 healthy male who served as a control. In 30 patients the ABC-Test of ejaculate speciments was compared with complement (C3) and coeruloplasmin content of the ejaculates using immunodiffusion technique. Contrary to the reports in the literature, however, elevated levels of complement (C3) and coeruloplasmin were not correlated with local infection of the prostate proven by ABC.

Antibody-coated bacteria in the ejaculate: a possible test for prostatitis.

An immunofluorescence technique was used to study antibody coating of bacteria in ejaculates from 14 healthy individuals and 51 patients with complaints compatible with the diagnosis of prostatitis. Quantitative bacteriological cultures in the ejaculate were positive in 2 healthy individuals (14%) and in 25 patients with prostatic symptoms (49%). Antibody-coated bacteria could be demonstrated in 25 patients with prostatic symptoms (49%), 8 of whom had negative bacterial cultures, but in none of the healthy individuals. All 5 patients with epididymitis had antibody-caoted bacteria in the ejaculate. The 13 patients with antibody-coated bacteria in the ejaculate were given antibiotic treatment and the bacteria disappeared in 8 cases. The results document the presence of a (presumably local) immune response in bacterial prostatitis. Antibody coating of bacteria in the ejaculate seems to be helpful in the diagnosis of bacterial prostatitis.

Lipid hemodialysis versus charcoal hemoperfusion in imipramine poisoning.

Previous experimental results have demonstrated the possibility of eliminating imipramine (14 C-IP) by hemodialysis. A simultaneous uptake of the substance by the polyvinyl chloride extracorporeal blood lines could be shown. Based on these results the imipramine absorption capacity of the blood lines and of the artificial kidney (Hollow Fiber Artificial Kidney, HFAK, Model 4) were studied. Imipramine (IP) absorption capacity of a usual blood-line set (arterial and venous, surface area 86,000 mm) was estimated to be 43 mg, and that of the HFAK to be 207 mg. Charcoal hemoperfusion (300 gm of coated activated coconut charcoal) eliminated more than 90% of IP from the blood within 3 hr if the initial IP blood concentration was 2 mg/ml. In comparison, lipid hemodialysis using 20% soybean oil as dialysate eliminated 95% of IP from the blood when the initial IP blood concentration was 1 mg/ml and 98% when the initial IP blood concentration was 2 mg/ml. In vivo studies on the elimination of IP by lipid (10%) hemodialysis demonstrated a substantial removal of the substance. Within 2 hr of treatment, 12% of the administered dose (75% of the LD50) was eliminated.

Haemodialysis in imipramine poisoning? An experimental study.

In the last several years an increasing number of severe imipramine intoxications have been observed. Though standard principles for the treatment of acute tricyclic poisoning have been established, nonetheless there still exists doubt on the most effective method of tricyclic removal in cases of massive overdose. Haemodialysis was successfully employed until now but has not found general acceptance as only insignificant amounts of imipramine could be recovered from the dialysate. An experimental clearance study was undertaken using radiolabelled imipramine (14C-I) to obtain insight into the usefullness of haemodialysis in imipramine poisoning. 14C-I clearances which were calculated in a closed circuit dialysis system ranged between 18 ml/min and 48 ml/min depending on the constitution of the dialysate, i.e. aqueous or lipid solution. Surprisingly a rapid and significant uptake of imipramine by the plastic material (polyvinylchloride) of the extracorporeal blood line system was detected. This escape of imipramine from the blood into the tubings explains the poor recovery of tricyclics from the dialysate, which discredited haemodialysis as a therapeutical method in imipramine poisoning. The results of our experiments may offer a new method of rapid tricyclic elimination in severe imipramine intoxications.

[Thrombotic occlusion of an arteriovenous Cimino shunt in acute pancreatitis (author's transl)].

An arteriovenous (Cimino) shunt in both right and left forearms clotted during an episode of acute pancreatitis in two patients on chronic haemodialysis. Systemic hypercoagulability (circulating fibrin monomers, shortening of r and k time in the thrombelastogram and shortening of the PTT-time) occurred in association with inhibition of fibrinolysis (prolongation of euglobulin lysis time). Localized thrombosis at the shunt is thought to be due to superimpostition of systemic hyper-coagulability on a local increase in platelet adhesiveness.

Pathophysiology and therapy of hypercalciuria in patients who form recurrent stones.

There are two alternative mechanisms that might be responsible for idiopathic hypercalciuria in recurrent stone formers: increased intestinal absorption of calcium with parathyroid suppression and overflow hypercalciuria (primary intestinal hyperabsorption) or renal calcium leak with compensatory hyperparathyroidism and intestinal hyperabsorption (primary renal-tubular hypercalciuria). In this study, urinary excretion of cAMP, the intracellular effector substance synthetised under parathyroid hormone stimulation, was found to be in the normal range. This finding would argue against intestinal hyperabsorption of calcium as the primary cause of hypercalciuria.
