Lithium-induced sinus node dysfunction.

A 74-year-old woman, on lithium carbonate treatment, developed symptomatic sinus node dysfunction and central nervous toxicity, which disappeared after discontinuation of the drug and when serum lithium fell from 2 to 1.27 mEq/L. Our review of the literature demonstrates that sinus node abnormalities can occur both in presence of therapeutic and toxic serum lithium levels and are frequently asymptomatic and completely reversible. All patients receiving lithium should have their pulse regularly recorded and the drug should be promptly discontinued if severe bradycardia or other rhythm disturbances appeared during the treatment.

Free-cortisol assay by immunoextraction: comparison with an equilibrium dialysis procedure.

We describe a new method for directly determining the apparent free cortisol concentration in plasma samples by use of an antibody-coated test-tube RIA. Buffer-diluted plasma or standard serum is added to antibody-coated test tubes, incubated at 4 degrees C for 4 h, and the solutions are aspirated. 125I-labeled cortisol is added to each tube and incubated for 3 h at 4 degrees C. Then the insides of the tubes are washed and their radioactivities counted. The standard curve is in terms of free cortisol, the standard serum solutions having been measured with an equilibrium dialysis procedure. Plasma samples (n = 155) from normal subjects and from various patients, measured with the new immunoextraction method and the equilibrium dialysis technique, gave results that correlated well (r = 0.847, p less than 0.001). Results by this direct RIA also correlate well with the clinical adrenocortical status of patients for whom data on total plasma cortisol may be misleading. This simple, easy RIA is suited to be the routine method for free cortisol in plasma.

[Pheochromocytoma and autoimmune hypothyroidism].

The association of multiple endocrine diseases is frequent and the coincidental involvement of the thyroid and adrenal glands is well recognized. On the contrary, two cases of hypo or hyperthyroidism have only been reported in literature: one concerning adrenal pheochromocytoma with simultaneous autoimmune hypothyroidism and another of a diffuse toxic goiter associated with pheochromocytoma. The purpose of the present report is to point out a new case of a pheochromocytoma associated with an autoimmune hypothyroidism in which the latter is florid and not biochemical.
