Introduction: Faster decline in serum thyroid hormone levels in hyperthyroidism is seen adding cholestyramine at conventional treatment in some studies (1.2).Design/methods: Retrospective controlled study. Follow-up: ±3 weeks.Patients with hyperthyroidism: 17 treated with antithyroid drugs (mean dose 35 mg/day) combined with cholestyramine (mean dose 12 g/day).Control group: 23 only treated with antithyr...

Introduction: Familial hypocalciuric hypercalcemia (FHH) is a benign disorder, with inappropriately elevated parathyroid hormone, without the complications of hypercalcemia (1). It is important to discriminate FHH from primary hyperparathyroidism (PHPT), because of the consequences on symptomatic disease and therapeutic approach. Ca/Cr clearance ratio will be <0.01 in FHH and most often >0.02 in PHPT (2). In patients with PHPT and vitamin D deficiency, low urinary calc...

Introduction: Pituitary lesions are quite often in the general population and can be symptomatic or not. Most are attributed to pituitary adenomas. Differential diagnosis also includes other causes, such as granulomatous diseases (sarcoidosis, histiocyttosis). Neurosarcoidosis is rare. Sarcoidosis pituitary infiltration is even more rare and usually reported in multifocal forms of the disease.Case report: We describe a 34-year old female with headache an...

Introduction: During embryogenesis the descent of the thyroid may not proceed normally and may stop at various sites from the base of the tongue to any site of the thyroglossal duct.Ectopic thyroid tissue, defined as thyroid tissue not located at its normal site (anterolaterally to the second and fourth tracheal cartilages) is rare. Most often, ectopic tissue is located in the base of the tongue.Case report: We report a 75-year old...

Introduction: Resistance to thyroid Hormones (RTH) is a syndrome characterized by reduced tissue responsiveness to thyroid hormones (TH).This results to constantly elevated levels of TSH despite high levels of free T3 (FT3) and free T4 (FT4).RTH is due to mutations of the gene encoding the b-isoform of the receptor of TH (THR-b gene), inherited in the autosomal dominant manner.Clinical expression of RTH varie...
