Pancreatitis associated with thiazide administration. A role for the parathyroid glands?

Twenty-one of a total of 72 patients with acute pancreatitis admitted to a university hospital over a three-year period were found to have "idiopathic" pancreatitis. Of these, six nonalcoholic patients without gallbladder disease were receiving one of the thiazide diuretics prior to the onset of pancreatitis. Three patients taken from an earlier series likewise had pancreatitis associated with thiazide administration and at the time of autopsy harbored parathyroid hyperplasia. It is suggested that both the parathyroids and the pancreas may be affected by thiazide administration, and that a history of ingestion of these drugs should be sought in patients who have idiopathic pancreatitis.

Thyroid neoplasms after radiation therapy for adolescent acne vulgaris.

There is a potential hazard of thyroid cancer after exposure to external irradiation for the treatment of adolescent acne vulgaris. We noted a 60% incidence of thyroid carcinoma among 20 patients with such a history, who were operated on for thyroid nodules during a five-year period. Eighty-three percent of the patients with carcinoma had either a follicular or a mixed papillary-follicular carcinoma; 17% had a papillary carcinoma; 33% had regional node metastases; none had evidence of distant metastases. The interval between radiation exposure and thyroidectomy ranged from nine to 41 years. This association of thyroid neoplasms and a prior history of radiation for acne vulgaris may be coincidental and therefore remains to be proved by retrospective surveys of large numbers of treated patients with appropriate controls.

Successful autotransplantation of the parathyroid glands during total thyroidectomy for carcinoma.

In a consecutive series of 118 total thyroidectomies during a period of 11 years, autotransplantation of one or more parathyroid glands was used in 64 patients. During the first nine years of this series, autotransplantation was used in only 25 per cent of the total thyroidectomies, with a 3 per cent incidence of permanent hypoparathyroidism. During the last two years, autotransplantation of the parathyroid was used in 89 per cent of 54 total thyroidectomies, with a zero incidence of hypoparathyroidism.

Total thyroidectomy and parathyroid autotransplantation for radiation-associated thyroid cancer.

In seventy patients with nodular thyroids and a history of radiation exposure, total thyroidectomy disclosed a 54% incidence of carcinoma; more than half of them had cervial node metastases; four had distant metastases. Fourteen patients required radical neck dissection. The carcinoma was multicentric (both lobes) in 45%. In four patients the carcinoma was found in the lobe contralateral to the one containing the palpable nodule. These findings support the advocates of total thyroidectomy for patients with a nodular thyroid and a history of radiation exposure, provided this operation can be performed with a low incidence of recurrent nerve palsy and hypoparathyroidism.

Osteosclerosis in primary hyperparathyroidism.

Osteosclerosis in adults with primary hyperparathyoidism is rare; the usual skeletal manifestation, when presented, is diffuse osteropenia. We describe a patient with generalized osteosclerosis in association with primary hyperparathyroidism. The findings are documented by conventional and fine-detail radiography, absorptiometric bone mineral analysis, quantitative microradiography and histologic examination of bone. The unique features are contrasted with the manifestations recorded in a recently studied group of 87 hyperparathyroid patients. The data presented here support a causal relationship in this patient between parathyroid hormone excess and the development of densely sclerotic bones.

Thyroid hemangioma.

A case is presented of a fifty-six year old man with a thyroid hemangioma presenting as a neck mass with tracheal deviation and unilateral vocal cord paralysis. A standard thyroid scan yielded equivocal findings. The diagnosis was determined preoperatively by the use of a 99m-technetium angiogram that disclosed the vascular nature of the lesion. Subsequent arteriography demonstrated the main arterial supply of the mass to be from both inferior thyroid arteries. Operative removal of the mass was accomplished through a standard transverse cervical incision. Pathologic study revealed that the vascular tumor involved both the surrounding normal thyroid parenchyma and also a microfollicular adenoma. This case points out the value of utilizing all available diagnostic means in atypical cases of thyroid disease.

Papillary clear cell carcinoma of the thyroid gland.

A case of an unusual papillary clear cell carcinoma of the thyroid gland is described. The patient expired 17 days after operative biopsy and thyroxine suppression. Special stains were helpful in differentiating renal cortical carcinoma and parathyroid malignant disease from primary papillary clear cell carcinoma of the thyroid. Ultrastructural features of this tumor may relate to the effects of thyroid stimulating hormone as well as the malignant nature of the tumor.
