Nelson's syndrome: incidence and prognosis.

Fifty patients bilaterally adrenalectomized for Cushing's disease were followed for 1 to 22 (mean, 12) years. In 14 of them (28%) Nelson's syndrome appeared within 1.5 to 12 (mean, 4.8) years after adrenalectomy. All the patients were deeply pigmented, 12 had a radiologically demonstrable tumour and six had visual defects. Plasma ACTH levels ranged from 450 to 8000 ng/l. However in every case at least one estimation during circadian studies equalled 2000 ng/l. One patient with an anaplastic pituitary tumour died 3 years after the discovery of the tumour. Anaplasia was also diagnosed in another patient with recurrence of pituitary tumour after a transsphenoidal operation. Symptoms of tumour infarction occurred in two patients, followed by clinical remission of Nelson's syndrome. In the majority of cases the course was benign. We conclude that all cases, however, should be followed indefinitely because Nelson's tumours are not infrequently aggressive.

Two pregnancies in a woman with Cushing's syndrome treated with cyproheptadine. Case report.

A young woman with Cushing's syndrome who had had amenorrhoea for six years was treated with cyproheptadine and became pregnant five months later. Treatment with cyproheptadine was continued till six weeks after delivery by which time all the features of Cushing's syndrome had disappeared. The baby developed normally but died of gastroenteritis when four months old. Two years later the patient became pregnant again without further treatment. Pregnancy and labour were uncomplicated and mother and son did well. A full remission of Cushing's syndrome was confirmed two months after delivery.

Electron microscopic and ultracytochemical investigations of thyroid C cells in primary hyperparathyroidism.

The subject of study were C Cells of the human thyroid in course of primary hyperparathyroidism caused by the presence of a single adenoma. C cells were estimated by routine electron microscopic technique and by cytochemical cholinesterase (ChE) reaction according to Iwayama in electron microscopic technique. The presence of single C cells and of a small agglomeration of these cells, parafollicularily localized was found in the thyroid gland. An electron dense reaction product was noticed on membraneous structures of C cells of the thyroid.

Adrenal scintigraphy with 131-I-adosterol.

A new adrenal scanning agent, Adosterol (131I-6beta-iodomethyl-19-norcholest-5(10)-en-3beta-ol) has been evaluated in three female patients with hypercorticism. In one case, characterised by recurrent adrenocortical hyperactivity after bilateral adrenalectomy, a remnant of adrenal tissue was detected. In two other cases, the presence of an adrenal tumour could be excluded. The scan made on the 6th day after the administration of Adosterol was found to be superior in quality to that made on the 13th day.
