Siskind and colleagues do not mention the impact of thyroid assays reference ranges on diagnosis management hypothyroidism.1 It is generally believed that assay differences are accounted for by specific intervals. We found, however, subclinical hypothyroidism (SCH) strikingly different depending stimulating hormone (TSH) free thyroxine …

MATHEMATICAL MODELING AND DYNAMICAL ANALYSIS OF THE OPERATION OF THE HYPOTHALAMUS – PITUITARY – THYROID (HPT) AXIS IN AUTOIMMUNE (HASHIMOTO’S) THYROIDITIS Balamurugan Pandiyan, B.S., M.S. Marquette University, 2011 This thesis is a mathematical modeling study of the operation of the negative feedback control through the hypothalamus-pituitarythyroid (HPT) axis in autoimmune (Hashimoto’s) thyroi...

Hypothyroidism is a common endocrine disorder resulting from deficiency of thyroid hormone or its effects on peripheral tissues. It usually is caused by an insufficient production of thyroid hormone by thyroid gland (primary hypothyroidism), but it could be also caused by inadequate secretion of either thyrotropin (ie. thyroid-stimulating hormoneTSH) from the pituitary gland (secondary hypothyr...

•Subclinical thyroid dysfunction is very common in patients with chronic heart failure (?10%). •There a U-shaped relation between Thyroid-Stimulating Hormone and mortality. hypothyroidism associated worse outcome univariable analysis, but the association disappears after adjustment for age natriuretic peptide level. weak significant increasing normal ejection fraction.

Osteoporosis-related fractures are one of the complications of Graves' disease. This study hypothesized that the different actions of thyroid-stimulating hormone receptor (TSHR) antibodies, both stimulating and blocking activities in Graves' disease patients might oppositely impact bone turnover. Newly diagnosed premenopausal Graves' disease patients were enrolled (n = 93) and divided into two ...

In a study at a primary care centre in a predominantly rural area of Sweden the records of all patients with established thyroid disease were scrutinised and 2000 consecutive adult patients screened with an immunoenzymometric thyroid stimulating hormone assay. The aims of the study were fourfold: firstly, to assess the total burden of thyroid disease in primary care centres in Sweden; secondly,...

Aims and Objectives: This study aimed to assess compare follicle-stimulating hormone (FSH), luteinizing (LH), prolactin, thyroid-stimulating (TSH) levels in normal fertile females, patients with primary infertility, early pregnancy loss (EPL). Methods: Patients were divided into three groups of 25 each. Group I consisted II EPL, C females acted as the control group. Hormone different compared s...

This study was designed to determine the effect of increase hyperthyrodisim on some hormones (Triiodothyronine, thyroxin, thyroid stimulating hormone) and biochemical parameters (creatinine, magnesium) 58 sample used in this at age (25-40 years), where samples were divided into two groups a rate 29 per group. The totals as follows: control group, group patients. It measured hormone Triiodothyro...
