38 cases of abdominal surgery in acute renal failure, checked anatomically by reintervention or autopsy, were analyzed. The authors emphasize the frequency of the state of shock (2/3 of the cases) and the misleading nature of local signs. They stress the value of routinely checking creatinine clearance in the preoperative check-up in order to screen for latent renal failure.

The effect of acute experimentally induced renal failure after intramuscular injection of glycerol on serum and urine GGTP, LAP and AP activities was studied in 30 rabbits. High doses of glycerol caused shock, myolysis and hemolysis, leading to acute renal insufficiency. Serum urea and creatinine levels significantly increased, there was proteinuria, and significant decrease in 24-hr diuresis, glomerular filtration, and urinary urea excretion. The changes in LAP and AP activities were significant, and in GGTP-nonsignificant. In the urine GGTP and LAP increased significantly, and AP nonsignificantly. Urinary excretion of AP increased significantly, and GGTP and LAP nonsignificantly. The highest activity and urinary excretion of GGTP and LAP were observed on the 2nd day, and of AP--on the 5th day of renal failure.

One case of Phenindione (PID) adverse reaction is reported. The patient showed a typical picture of immunological reaction to the drug. In spite of severe bacteremia, she recovered. Only 33 cases of PID intolerance are reported in the literature. In all these patients, renal failure occurred. Superinfection is the most frequent cause of death. PID adverse reaction should be evoqued in the presence of signs such a fever, asthenia, anorexia and cutaneous reaction. The PID should be stopped immediatly but renal failure yet develops. During a PID treatment, frequent evaluation of blood azotemia, creatinine and proteinuria should be performed.

Two infants with lethargy, vomiting, convulsions, coma and marked metabolic acidosis were found to have very high concentrations of methylmalonic acid in their serum and urine. In vitro studies of fibroblasts demonstrated that the infants had different variants of methylmalonic acidemia.Vitamin B(12) was given in two different forms at 1 month of age and at 12 months of age. Each trial continued for 4 months but neither infant showed a clinical or biochemical response.In both infants hyperglycinemia, neutropenia and thrombocytopenia developed during acute metabolic crises only. Hypoglycemia was found in patient 2. Hyperammonemia was severe in patient 2 during acute crises but never appeared in patient 1. When clinically well, both infants continued to excrete abnormal amounts of methylmalonic acid in the urine and both had persistent compensated metabolic acidosis.Marked hyperuricemia developed in patient 1 at 18 months of age and led to progressive renal failure. Allopurinol therapy was necessary to keep the uric acid concentration within the normal range. Renal function returned to normal, as indicated by a marked increase in the renal clearance of creatinine and uric acid.Patient 1 is physically and mentally retarded, and has moderate hypotonia, hepatomegaly and persistent vomiting. Patient 2 has developed normally.The urine concentrations of methylmalonic acid in the four parents were normal.

1 Nadolol excretion was studied in 24 patients with chronic renal failure. 2 The amount of nadolol excreted during the 120-h period after receiving the drug ranged from less than 1% in functionally anephric, patients up to 11.5% in patients with average creatinine clearance of 57.9 +/- 3.6 ml/min/1.73 m2. 3 Renal clearance of nadolol was found to correlate with creatinine clearance; nadolol elimination is retarded in patients with renal failure. 4 Nadolol serum half-life is prolonged in proportion to the remaining renal function. Therefore, dosage intervals in renal patients receiving nadolol should be adjusted to creatinine clearance. 5 Haemodialysis effectively reduced serum concentration of the drug; it may therefore be a useful therapy for drug intoxication.

Two patients with kidney transplants had hypertensive encephalopathy and rapidly progressive kidney failure 10 weeks and 18 months postoperatively. In one patient renal failure was associated with erythrocytosis. Absence of proteinuria, despite progressive renal insufficiency in both patients, suggested that these abnormalities were not due to rejection episodes. Subsequently, angiography proved that each of these patients had renal-artery stenosis. Surgical repair of this lesion increased creatinine clearance at least threefold, and the hypertension and erythrocytosis disappeared. Apparent "rejection" episodes in which there is no proteinuria should alert clinicians to the possiblity of renal-artery stenosis of the graft. Restoration of kidney function and amelioration of hypertension may follow revascularisation, even after many months of renal ischaemia producing severe uraemia.

EEGs wre recorded from renal patients to determine if there are quantifiable characteristic changes in the EEG was quantified by calculating the percentage of spectral power in the bandwidth 3-7 c/sec referrred to a frequency range of 3-13 c/sec and by computing the mean frequency of the dominant rhythm in the EEG. Blood urea nitrogen and creatinine concentrations, as well as a self-assessment of the patient's clinical condition, were recorded. The general finding of this research is that EEG slowing, as evaluated by power spectral techniques, is correlated with uremia-associated variables. 1. In a non-dialyzed patient population with renal failure, slowing in the EEG was found to be directly corelated with increased creatinine concentrations. 2. Quantitative measures of slow wave activity computed using power spectral techniques were found to be highly corelated with an estimate of slowing made by an electroencephalographer. 3. Compared with undialyzed azotemic patients, malignant hypertensive patients with comparable serum creatinine concentrations typically displayed increased slow wave activity, while slowing was generally reduced in the dialyzed patient population. 4. A series of EEGs recorded from one patient during the first three dialyses of her life revealed that slow wave activity decreased during each successive dialysis. In another patient, all quantified EEG values recorded prior to renal transplantation significantly improved after transplantation...

In January, 1973, a study was established to evaluate, prospectively and independently, the growth and psychosocial adaptation of children in end-stage renal failure treated by home haemodialysis at Guy's Hospital and the Royal Free Hospital. By January, 1975, 26 children had entered the study, but 2 died before they were established on home haemodialysis. In this paper a specified 1-yr period starting 6 mo after the onset of haemodialysis was selected for analysis. School attendance, diet, plasma-biochemistry, bone disease, growth, and emotional symptoms were investigated in each child. Rehabilitation was satisfactory, and average school attendance was 65%. Growth in all the prepubertal children was poor, whereas in most pubertal children it was adequate. At the end of the year, only 5 children were emotionally disturbed, but half the families had stress symptoms. The children at Guy's Hospital were dialysed more intensively than those at the Royal Free Hospital, and they had significantly lower mean plasma urea and creatinine concentrations and a greater energy and protein intake. On the other hand, the children at the Royal Free Hospital had a better school attendance. We conclude that home haemodialysis is an acceptable treatment for children in end-stage renal failure.

The clinical pharmacology of bleomycin administered by continuous intravenous infusion over a 4 to 5 day period was examined by nine patients. Patients receiving 30 units per day attained an average steady state plasma level of 145.8 (+/- 43.1) ng/ml bleomycin. Elimination of bleomycin was initially described by first order rate kinetics (t 1/2 = 1.32 +/- 0.39 hour). However, at times greater than 12 hours following termination of infusion, a second elimination phase was observed (t 1/2 = 8.9 +/- 2.7 hour). There was also a high correlation between renal bleomycin clearance and creatinine clearance. The importance of renal clearance was indicated in a patient with renal impairment. This patient attained a steady state bleomycin concentration of 1046 ng/ml and exhibited a terminal elimination half-life of 33 hours. Overall plasma clearance of bleomycin (Qbeta) was generally greater than renal clearance, indicating that a nonrenal clearance mechanism was also important in bleomycin elimination. This nonrenal mechanism became especially apparent during renal failure.

Computerized EEG was performed in 20 patients with renal failure before and after haemodialysis (HD), applying spectral analysis and Hjorth's EEG descriptors in EEG quantification, correlation and factor analysis as statistical procedures to analyse the connections of EEG, blood variables and psychological performance. The main results were: (1) Moderate uraemic encephalopathy -- according to Kiley's (1971) standards -- was present in most of our patients, before and after HD. (2) Before HD, EEG slowing was most strongly connected with the creatinine level and EEG acceleration with hyperkalaemia, which in most cases accompanied a high urea level. (3) Significant EEG changes after HD were: decrease of percentage delta activity, increase of Hjorth's 'mobility', decrease of Hjorth's 'complexity'. (4) The theta/alpha ratio (Matousek 1968) was significantly correlated with the patient's general clinical state after HD. (5) Visual discrimination, memory and maximal tapping speed improved significantly after HD. Only Hjorth's EEG parameters were correlated with test performance in that patients with low voltage and fast EEGs did worse in visual discrimination.
