Radioiodine uptake following iodine-131 therapy for Graves' disease: an early indicator of need for retreatment.

Forty-five patients with Graves' disease were studied prospectively to determine if 24-hour I-131 uptake measurements alone or in combination with serum thyroid hormone levels at six weeks would determine the necessity for retreatment of the thyrotoxicosis. All patients with an I-131 uptake greater than 30% at six weeks required retreatment. No patient with an I-131 uptake of less than 15% required retreatment. Patients with uptakes between 15% and 30% were variable. An elevated free thyroxin index at 6 weeks is not helpful to determine which patients will remain thyrotoxic. Patients with a free thyroxin index within the normal range at six weeks can be predicted to be euthyroid by 12 weeks if their 24-hour I-131 uptake is between 15% and 30% and to be hypothyroid if their 24-hour I-131 uptake is below 15%. There was no difference between patient groups treated initially with antithyroid medication and those who were not.

Meningoencephalitis complicated by pituitary insufficiency and a spontaneously resolving suprasellar mass.

A 53-year-old woman presented with acute meningoencephalitis associated with anterior and posterior pituitary insufficiency. A computed axial tomogram (CT) of the head revealed a suprasellar mass. The meningoencephalitis, presumably of bacterial origin, resolved after antibiotic therapy and, on a repeat CT, the suprasellar mass had disappeared. Five months after the initial illness, the patient's diabetes insipidus had resolved, anterior pituitary function had improved, and there was no sign of the suprasellar mass. The presence of a suprasellar mass in conjunction with acute meningoencephalitis and anterior and posterior pituitary insufficiency should raise the suspicion that the mass is not neoplastic and may be infectious or inflammatory in origin.

Endocrine emergencies. Adrenal crisis, myxedema coma, and thyroid storm.

Each of the endocrine emergencies discussed here--adrenal crisis, myxedema coma, and thyroid storm--represents decompensation of a long-standing endocrine disorder and is precipitated in most cases by some stressful event. Each necessitates immediate, aggressive therapy. Even with such therapy, the mortality rate remains 30% to 50% for myxedema coma and 30% to 40% for thyroid storm. Therapy must be instituted on the basis of strong clinical suspicion, without delay for results of specific hormone assays to confirm the diagnosis. Although some risks may be inherent in this approach, they are minimal compared with the risks of delaying therapy until laboratory confirmation can be obtained. Immediate therapy consists of specific measures to correct the hormone deficit or excess; the precipitating cause should then be sought and treated.

Lactose and casein content of nonpuerperal breast secretion.

Twenty-seven patients with nonpuerperal breast secretion were evaluated for the presence of casein and lactose in the secretions. Only two of seven patients with brownish or greenish secretions were positive for both lactose and casein although an additional six patients were positive for casein alone. Two patients with clear breast secretions were positive for both casein and lactose. However, 16 of 17 patients with milky or white secretions were positive for both casein and lactose. Although casein and lactose are more likely to be present in white breast secretions, other types of breast secretions may also contain these constituents.

Pharmacodynamics of propylthiouracil in normal and hyperthyroid subjects after a single oral dose.

Serum levels of propylthiouracil were measured in 8 normal persons and in 7 patients with hyperthyroidism after a single, 300 mg, oral dose of 6-n-propyl-2-thiouracil (PTU). The patients with hyperthyroidism were restudied after 3, 6, and 9 weeks of individualized treatment with PTU. The serum half-life of the drug in normal subjects was 1.65 h. In patients with hyperthyroidism the serum half-life was similar, and it did not change significantly as the euthyroid state was achieved.
