Hyperparathyroid crisis and posterior mediastinal parathyroid adenoma: a case for preoperative localization.

Hyperparathyroid crisis is a rare, life-threatening condition that requires prompt removal of the involved parathyroid gland(s). This report describes a patient with hyperparathyroid crisis caused by a mediastinal parathyroid adenoma, which was localized before operation and removed at the initial operation, without neck exploration. Surgical approaches to hyperparathyroid crisis and the importance of preoperative localization studies are discussed.

Hypoglycemia in pregnancy. Occurrence due to adrenocorticotropic hormone and growth hormone deficiency.

Severe symptomatic hypoglycemia (serum glucose level, 24 mg/dL) developed in a 23-year-old, 147.3-cm-tall woman during her late second and third trimesters of pregnancy. Endocrine studies disclosed insulin levels less than 2 microU/mL; growth hormone level less than 3 ng/mL; and cortisol level less than 1 microgram/dL. Hydrocortisone therapy corrected her hypoglycemia, and she was delivered of a healthy female infant. Postpartum, her evaluation included normal thyroid function studies, a normal thyroid-stimulating hormone response to protirelin (thyrotropin-releasing hormone), normal serum and urine gonadotropin levels, normal serum prolactin, normal sella turcica tomograms, and a normal EMI brain scan. Urine 17-hydroxycorticosteroids increased during a four-day cosyntropin infusion, but failed to rise after metyrapone administration. The growth hormone level failed to rise after stimulation with levodopa and propranolol administration. The patient was believed to have idiopathic partial hypopituitarism, with hypoglycemia being due to adrenocorticotropic hormone (ACTH) and growth hormone deficiency and the drain of maternal glucose by the fetus. It is suggested that pregnant women with symptomatic hypoglycemia be treated with glucocorticoids while awaiting the results of their endocrine evaluation.

Parameters of thyroid function in patients with active acromegaly.

In order to determine if acromegaly per se may be associated with abnormalities in thyroidal economy, serum thyroxine-binding globulin (TBG), resin T3 uptake, total and free T4, T3, and reverse T3 concentrations were measured in 21 patients with active acromegaly. Mean (+/- SE) total T4, T3, and reverse T3 levels were 7.1 +/- 0.2 microgram/dl, 111 +/- 4 ng/dl, and 45 +/- 2 ng/dl, respectively, and the mean TBG concentration was 3.6 +/- 0.2 mg/dl. Similarly, mean free T4, T3, and reverse T3 concentrations were 2.4 +/- 0.09 ng/dl, 383 +/- 22 pg/dl, and 118 +/- 7 pg/dl, respectively. None of these values is significantly different from normal and the thyrotropin response to thyrotropin-releasing hormone was also normal. In contrast to several earlier reports, these data suggest that parameters of thyroid function are generally normal in patients with active acromegaly.

Hypothyroidism after x irradiation to the neck: three case reports and a brief review of the literature.

Three patients who developed hypothyroidism after x irradiation to the neck are presented. The first two cases demonstrate that patients can develop clinical and chemical hypothyroidism after a very short interval following radiotherapy. Hypothyroidism developed in the first patient in the absence of surgical manipulation of the neck, or a large iodine load 4 months after receiving 6800 rad of x-ray therapy to his neck for carcinoma of the larynx. The second patient developed hypothyroidism approximately 6 months after his radiotherapy for carcinoma of the esophagus. Both of these patients demonstrated high titers of serum antithyroid antibodies. A third patient with Hodgkin's disease did not manifest clinical symptoms and signs of hypothyroidism until 6 years after radiation therapy. These cases demonstrate the variability of onset of hypothyroidism after radiotherapy and emphasize the need for careful evaluation of thyroid function before and after neck irradiation.
