Introduction: A significant body of literature supports that 25(OH)vitD deficiency is associated with insulin resistance. We studied the prevalence of 25(OH)vitD deficiency across the spectrum of glucose metabolism.Design: The study participants (441 total, 362 females (82.1%) and 79 males (17.9%)) had a mean age (±S.D.) of 64.59 (±9.44) years, range: 32–92 years. The study population was divided into two groups: Individuals...

Background: 25 hydroxy vitamin D (25(OH)D) vitamin levels are positively associated with bone mineral density and season, time of day and sun exposure duration influence its synthesis. Variations in daylight throughout the year and zenith angle, depending on the latitude of residence, influence u.v. solar radiation which is closely related to serum 25(OH)D levels. The aim of this study was to investigate the degree of seasonal variation of 25(OH)D serum levels in a population-...

Introduction: Postsurgical hypoparathyroidism, (postHypoP), is a common complication of total thyroidectomy. We studied the variation of biochemical and hormonal parameters in patients who underwent total thyroidectomy.Design: The study included 106 females of a mean age (±S.D.) 51.03 (±13.42) years who underwent total thyroidectomy for multinodular goiter. We estimated the value of 25(OH)vitD, PTH, CT, adjusted Ca, P, and alkali...

Background: Many patients with differentiated thyroid cancer (DTC) are treated with radiodine (I-131) after thyroidectomy, while they are hypothyroid and all are submitted to withdrawal of LT4 periodically for the evaluation of their disease. Among the tests used for follow-up is serum thyroglobulin (Tg) as a tumor marker, and occasionally, total body scan with I-131. Maximal sensitivity of the aforementioned tests is established in the hypothyroid state, under elevated thyrot...
