Primary hyperparathyroidism is not commonly diagnosed during pregnancy. For pregnant women with mild, asymptomatic disease, surgery can be avoided unless the degree of hypercalcemia becomes more severe or they develop complications. However, there are no evidence-based guidelines to assist clinicians regarding the management of primary hyperparathyroidism during pregnancy. When surgery is deemed necessary during pregnancy, the second trimester is generally considered to be the optimal time. We r...

Background Primary hypothyroidism can cause both hyperprolactinemia and pituitary hyperplasia. The degree of hyperprolactinemia is generally modest, and rarely do prolactin concentrations exceed 100 ng/mL (4.34 nmol/L). This combination of hyperprolactinemia and pituitary gland enlargement might raise suspicion for a prolactinoma or a nonfunctioning adenoma limiting the ability of hypothalamic dopamine to inhibit prolactin production, the so-called “stalk effect.” Case Description We describe a ...

Hypercalcemia may be seen in a variety of clinical settings and often requires intensive management when serum calcium levels are dramatically elevated. All of the many etiologies of mild hypercalcemia can lead to severe hypercalcemia. Knowledge of the physiologic mechanisms involved in maintaining normocalcemia and basic pathophysiology is essential for making a timely diagnosis and hence prompt institution of etiology-specific therapy. The development of new medications and critical reviews of...

Abstract Aims: Vitamin D (VD) deficiency has become a worldwide epidemic, particularly affecting African Americans (AA). VD deficiency has been implicated in the excessive rate of complications associated with diabetes in AA. Blood levels of VD binding protein (VDBP) and glutathione (GSH) are lower in AA compared with those in Caucasians. This study tested the hypothesis that lower GSH levels are linked to VDBP and VD deficiency in AA-type 2 diabetic (AA-T2D) patients. Blood was analyzed from T2...

Context: Hypercalcemia associated with lymphomas can be secondary to increased calcitriol [1,25(OH)2 vitamin D3], PTHrP, or osteolytic metastases. Objective: A case of calcitriol-mediated hypercalcemia secondary to non-Hodgkin lymphoma in a patient with postsurgical hypoparathyroidism is presented. Design and Setting: Single patient managed at a tertiary health care facility in the United States. Patient: A 55-year-old white woman had a total thyroidectomy and radioiodine ablation for a 3.5-cm f...

Abstract Pituitary adenomas are the most common tumors of the sellar region, but the occurrence of spherical amyloid deposits in a pituitary adenoma is rare. We describe the clinical features, radiologic characteristics, and pathologic findings of 45-year-old man who presented with galactorrhea, hypogonadism, and hyperprolactinemia who had a pituitary adenoma with extensive spherical amyloid deposits. Approximately 30 cases have been reported, almost exclusively in patients with prolactinomas. T...

Abstract African Americans (AA) have a higher incidence of cardiovascular disease and vitamin D (VD) deficiency compared with Caucasians. Hydrogen sulfide (H2S) is an important signaling molecule. This study examined the hypothesis that blood levels of H2S are lower in AA type 2 diabetic patients (T2D). Fasting blood was obtained from T2D and healthy controls. Results showed a significant decrease in plasma levels of cyclic adenosine monophosphate (cAMP) and H2S in AA T2D but not in Caucasian T2...
