Analgesic nephropathy in Canada: a retrospective study of 351 cases.

Data concerning 351 patients with analgesic nephropathy was obtained by a survey of Canadian nephrologists and suggested an incidence of at least 20, and of perhaps 50 cases per million population. Renal function at the time of diagnosis (as judged by serum creatinine level) was normal in 15%, mildly to moderately impaired in 59%, and severely impaired in 26% of cases. Follow-up serum creatinine level in 222 cases showed that renal function became worse in 42% of cases, with terminal renal failure developing in one-half of these patients. However, significant improvement in kidney function was observed in 25% of patients. Cessation of analgesic abuse considerably increased the likelihood of improvement in renal function.

Assisted circulation following myocardial infarction: a review of 25 patients treated before 1971.

Twenty-five patients with impending death from myocardial infarction were treated with assisted circulation. Of these, 19 had suffered cardiac arrest from which they could not be resuscitated and six were in severe, intractable and expectedly terminal cardiogenic shock.All patients were treated by venoarterial bypass employing a bubble oxygenator. Assistance was continued for an average duration of one hour and 45 minutes at a flow rate between two and four litres per minute. The patients all showed improved cerebral, pulmonary and renal function and acid-base values returned to normal.Five patients survived for at least one month and two were improved; hence 28% of these otherwise terminal patients were helped by this technique of assisted circulation.

Primary hyperparathyroidism and proximal renal tubular acidosis: report of two cases.

Two cases of primary hyperparathyroidism due to single parathyroid adenomas presented with the additional feature of hyperchloremic acidosis. The defect in urinary acidification responsible was not of the distal or gradient-limited type since both patients could lower urine pH adequately. However, there was a defect of bicarbonate reabsorption, an abnormality referred to as the proximal or rate-limited type of renal tubular acidosis. It is suggested that this defect represents an exaggeration of the physiological effect of parathormone on bicarbonate reabsorption and may be responsible for the frequent finding of hyperchloremia in association with primary hyperparathyroidism as well as for the urinary bicarbonate-wasting associated with a variety of causes of secondary hyperparathyroidism.

Fecal and salivary electrolytes in the diagnosis of primary aldosteronism.

Fecal and salivary sodium and potassium concentrations were measured in 22 hypertensive patients with hypokalemia who were undergoing investigation for primary aldosteronism due to an adrenocortical adenoma (Conn's syndrome). Of eight patients with a high aldosterone secretion rate, five had clearly low fecal Na/K ratios, (including all four patients with Conn's syndrome), in three the ratios were equivocal. Of 14 patients with hypertension and a normal aldosterone secretion rate, none had a sufficiently low fecal Na/K ratio strongly to suggest hyperaldosteronism, although two were borderline. Salivary electrolyte concentrations were not as consistent an indicator of mineralocorticoid hormone excess. Estimation of fecal sodium and potassium concentrations may be useful in the diagnosis of mineralocorticoid hormone excess and in assessing the results of therapy.
