Acute myocardial ischemia is a rare and possibly life-threatening manifestation of hyperthyroidism. We describe a 48-year-old woman with severe coronary vasospasm associated with hyperthyroidism. The patient presented with chest pain and increasing shortness of breath for several days. Acute non-ST elevation myocardial infarction was diagnosed. Coronary angiography revealed diffuse vasoconstric...

Seven patients suffering from hyperthyroidism have been carefully studied. An analysis of their experimental data provides definite evidence in favour of an associated hyperparathyroidism being the direct cause of the excessive mobilization and excretion of calcium and phosphorus. Two patients suffering from hyperthyroidism with an associated hypoparathyroidism were studied. Both patients were ...

the influence of hypo- and hyper-thyroidism on spermatogenesis was studied in 60-day-old adult malewistar rats. to confirm hypo- and hyper-thyroidism, the concentration of plasma thyroid hormones wereassayed by radioimmunoassay. the hypothyroid state, induced by administration of 25 mg/kg/daymethimazole for 5 successive days, resulted in significant decrease in the number of sertoli cells, sper...

BACKGROUND Hyperthyroidism has been linked with different morbidities, like atrial fibrillation, stroke and diabetes mellitus. However, our knowledge regarding the extent and temporal relation between hyperthyroidism and other diseases is fragmented. Here, we aimed at evaluating various morbidities before and after the diagnosis of hyperthyroidism. METHODS Observational cohort study. From nat...

OBJECTIVE Apathetic hyperthyroidism can be misdiagnosed or diagnosed late, and older patients are often susceptible to adverse effects of treatment for thyrotoxicosis. The aim of this study was to identify factors associated with apathetic hyperthyroidism. METHODS We retrospectively examined serum calcium, phosphorus and bone-specific alkaline phosphatase (BAP) levels and thyroid-associated v...

OBJECTIVE To compare bone mineral density (BMD) of the lumbar spine (L1-L4), total hip (TH), and femoral neck (FN) analyzed by Dual Energy X-ray Absorptiometry (DXA) in premenopausal women with hyperthyroidism and in healthy premenopausal women. MATERIAL AND METHOD Cross-sectional study included 49 premenopausal women with hyperthyroidism and 49 healthy premenopausal women. Age, weight and bo...
