Inappropriate secretion of antidiuretic hormone in pneumonia

Non-tuberculous pneumonia is an extremely rare cause of the syndrome of inappropriate secretion of antidiuretic hormone (ADH). A patient is described who had lobar pneumonia presenting as an acute confusional state due to hyponatraemia resulting from this cause.

Plasma concentrations of tryptophan and other amino acids in manic-depressive patients

Plasma tryptophan concentrations were determined in serial blood samples from a short cycle (two to three day) manic-depressive patient and four manic-depressive patients with longer (60 day) affective cycles. Tryptophan levels varied significantly with affective state in the short cycle patient and one of the longer cycle patients. Correlation in the short cycle patient was better with blood samples taken at 3 p.m. than at 9 a.m.

Clinical evaluation of perhexiline maleate in patients with angina pectoris

This paper reports a double-blind trial of a new antianginal drug, perhexiline. Fifty-five patients suffering from angina pectoris were studied for periods of 12 or 24 weeks in a cross-over comparison against a placebo in four centres in the United Kingdom and Ireland. Perhexiline was effective in most patients as judged by reducing the number of anginal attacks in 84% and the consumption of glyceryl trinitrate tablets in 64%. The major side effect, dizziness, noted in one-third of the patients, may be dose/body-weight related. Perhexiline is a valuable new agent for the treatment of patients with angina, especially those who do not respond to other antianginal agents.
