The importance of growth hormone and liothyronine in induced hypocalcaemia in hypophysectomized animals.

The resistance to hypocalcaemia induced by synthetic salmon calcitonin (SCT) was studied in intact and hypophysectomized rats. The recovery from hypocalcaemia was greatly impaired in the latter group, but this was normalised by small doses of purified human growth hormone (GH). The initial hypocalcaemic response to SCT was delayed in the hypophysectomized rats. This was not affected by treatment with GH, but normalised by substitution with liothyronine. We conclude that GH accelerates the recovery from hypocalcaemia in hypophysectomized animals, perhaps by a stimulation of parathyroid activity, while thyroid hormone accelerates the initial hypocalcaemic response to SCT, probably by restoring the reduced rate of bone resorption.

Fine needle and open biopsy in thyroid disorders.

The diagnostic value of cytological, serological and scintigraphical examination was evaluated in 20 histologically verified cases of thyroid disorder. The predictive values of specificity as to malignancy, thyroiditis and thyroid autoantibodies were respectively 0 percent (0-71), 80 percent (28-99) and 75 percent (19-99), and the predictive values of sensitivity were 88 percent (64-99), 100 percent (78-100) and 94 percent (70-100). Cold nodules were malignant in 40 percent. Fine needle biopsy can be used as a supplementary test without any risks and is a valuable aid in the diagnosis of Hashimoto's thyroiditis, but not in the diagnosis of malignant lesions. If any clinical or scintigraphical (cold nodule) suspicion of malignancy exists, a surgical biopsy must be done.

Diazoxide in the management of severe hypertension.

Fourteen patients with severe hypertension have been given i.v. diazoxide in a dosage of 5 mg/kg b.wt. The material comprised 2 patients with malignant nephrosclerosis, 4 with chronic nephropathy and severe reduction of renal function, 1 patient with chronic pyelonephritis, 1 with renovascular hypertension and 6 patients with essential hypertension and in malignant phase. All patients attained a controllable blood pressure. Eight patients remaining needed only one injection, while the remaining patients required 2-5 injections, and concomitant furosemide therapy. The retinopathy improved in most patients and renal function was unchanged in the azotemic patients. No serious adverse effects were seen, except one hypotensive episode. Diazoxide is easy to handle, dosage can be predetermined, monitoring is simple and we find diazoxide to be a valuable drug in severe hypertension.
