- ItemAssociation of adrenal medullar and cortical nodular hyperplasia - A report of two cases with clinical and morpho-functional considerations(HUMANA PRESS INC, 2006) Valdes, Gloria; Roessler, Eric; Salazar, Ivan; Rosenberg, Helmar; Fardella, Carlos; Martinez, Pedro; Velasco, Alfredo; Velasco, Soledad; Orellana, PilarArterial hypertension of adrenal etiology is mainly attributed to primary hyperaldosteronism. However, subtle expressions of hyperadrenergic or glucocorticoid excess can also generate arterial hypertension. The present report describes two hypertensive patients cataloged as resistant essential hypertensives, in whom adrenal masses were found incidentally, who highlight the need to recognize these tenuous clinical or laboratory presentations. Case 1 was a 50-yr-old female with hyperadrenergic hypertension associated to a left adrenal node, normal cortisol and aldosterone:renin ratio, marginally increased urinary normetanephrine, and a positive I-131 MIBG radioisotope scan. Adrenalectomy normalized blood pressure and urinary metanephrines. Pathology showed a hyperplastic adrenal medulla associated to a multinodular cortical hyperplasia. Case 2 was a 62-yr-old female with progressive hypertension, a slight Cushing phenotype, non-suppressible hypercortisolism, normal urinary metanephrines, and bilateral adrenal nodes. Bilateral adrenalectomy and subsequent replacement normalized blood pressure and phenotypic stigmata. Pathology demonstrated bilateral cortical multinodular hyperplasia and medullary hyperplasia. The clinical study in both patients was negative for MEN. The apparently rare association of cortical and medullary lesions presented by both patients is probably overlooked in routine pathology exams, but should be meticulously searched since the crosstalk between the adrenal cortex and medulla may prompt dual abnormalities.
- ItemGuidelines of the Chilean Endocrinology Society for the correct clinical use of bone densitometry(SOC MEDICA SANTIAGO, 2018) Barberan M, Marcela; Campusano M, Claudia; Trincado M, Patricio; Oviedo G, Sofia; Brantes G, Sergio; Sapunar Z, Jorge; Canessa, Jose; Cid, Pia; Escobar, Freddy; Eugenin, Daniela; Florenzano, Pablo; Gajardo, Hector; Gonzalez, Gilberto; Illanes, Francisca; Jimenez, Beatriz; Martinez, Carolina; Miranda, Edith; Rivera, Sandra; Salman, Patricio; Trejo, Pamela; Velasco, SoledadOsteoporosis is a silent and frequent disease, which increases fracture risk Approximately half of women and one of five men over 50 years old will suffer an osteoporotic fracture throughout their lives. Dual-energy x-ray absorptiometry (DXA) allows a real bone mineral density (BMD) measurement in different parts of the skeleton and is considered the "gold standard" for quantifying osteoporosis with high accuracy and precision. The Board of the Chilean Society of Endocrinology and Diabetes (SOCHED) required from the Bone Disease Study Group to develop a consensus about the "Correct use of bone densitometry in clinical practice in Chilean population". Therefore, we elaborated 25 questions which addressed key aspects about the indications for a DXA scan, and the details of how to perform and report this test. Since some of the evidence obtained was of low quality or inconclusive, we decided to create a multidisciplinary group of national experts in osteoporosis to develop a consensus in this subject. The group consisted of 22 physicians including endocrinologists, gynecologists, geriatricians, radiologists, rheumatologists and nuclear medicine specialists. Using the Delphi methodology to analyze previously agreed questions, we elaborated statements that were evaluated by the experts who expressed their degree of agreement. The final report of this consensus was approved by the SOCHED board.
