BACKGROUND Many reports have supported the relationship between high preoperative TSH levels and risk of thyroid cancer in nodular thyroid disease (NTD). OBJECTIVES We investigated whether TSH levels are related to the risk of differentiated thyroid carcinoma (DTC) in patients who have undergone total thyroidectomy for NTD. The relationship between TSH and size of malignant nodule was investi...

OBJECTIVE To determine the prevalence of congenital hypothyroidism (CH), permanent and transient CH. METHODS From November 2006 to September 2007, 63031 newborns were screened by measuring serum TSH obtained by heel prick. The neonates who had a TSH≥5mU/L were recalled for measurement of serum T(4), thyroid stimulating hormone (TSH) and TSH receptor blocking antibodies (TRBAb) in venous sampl...

background: although phototherapy has been used for more than 60 years it has some complications. the light waves produced from phototherapy reduce melatonin concentration in newborns with subsequent hypocalcemia. we aimed to assess the effect of head covering on calcium and magnesium levels in full term newborns during phototherapy. methods: in this randomized controlled trial, 72 full-term ic...

Background and Objective: Chronic kidney disease (CKD)  determined by permanent kidney damage. Due to the similarity of clinical symptoms of hypothyroidism with CKD, hypothyroidism may be neglected and remain untreated. The goal of our study was to evaluate the rate of hypothyroidism in CKD patients who need hemodialysis. Materials and Methods: This is a cross-sectional research. The sampling ...

The pituitary-Thyroid axis of 12 Acromegalic patients was evaluated by measurement of the concentration (Total and free of thyroxine T4, T3 and revers T3 (rT3) and TSH, GH and prolactin before and after in stimulation with TRH. Using an ultra­sensitive method of TSH measurement (IRMA) basal serum TSH levels of patients (0.76, 0.07-l.90mlU/L) were found slightly but significantly (P < 0.01), low...
