in this study 93 hirsute females (ferryman and gallway score > 8) referred to institute of endocrinology & metabolism and office were assessed. baseline testosterone (tes), dehydroepiandrosterane sulfate (dhea-so4). follicular stimulating hormone (fsh). leuteinizing hormone (lh), prolactin (prl), thyroid stimulating hormone (tsh), baseline 17 hydroxyprogesterone (17 ohp) and in some cases acth ...
idase (TPO) and incorporation into tyrosyl residues along the thyroglobulin (Tg) backbone. The thyroid hormones T3 and T4 are synthesized by coupling of two iodotyrosine residues and stored in the colloid. All of these steps are stimulated by pituitary-derived thyroid stimulating hormone (TSH), which interacts with the TSH receptor at the basolateral membrane of thyroidal cells, through the cAM...
The double antibody radioimmunoassay of serum thyroid-stimulating hormone (TSH) allows measurement of circulating levels of the hormone in most normal subjects. The serum TSH level in normal subjects is 1.6 +/- 0.8muU/ml. Patients with non-toxic goitre and acromegaly have normal TSH levels. Values are always raised in hypothyroid patients (with primary thyroid disease) and are significantly low...
Ghrelin is a peptide hormone produced mainly in the gastrointestinal tract known to regulate several physiological functions including gut motility, adipose tissue accumulation and hunger sensation leading to increased bodyweight. Studies have found a correlation between the plasma levels of thyroid hormones and ghrelin, but an effect of ghrelin on the human thyroid has never been investigated ...
Context Serum thyroid hormone levels differ between children and adults, but have not been studied longitudinally through childhood. Objective To assess changes in thyroid-stimulating hormone (TSH) and thyroid hormone levels over childhood and their interrelationships. Design Cohort study. Setting The Avon Longitudinal Study of Parents and Children, a population-based birth cohort. Part...
Background. For unknown reasons, the prevalence of thyroid autoimmune disorders is higher in patients with Down's syndrome than in the general population. The present case strongly supports a recent evaluation of propagating screening for thyroid disease in this group of patients to assure early diagnosis of hypothyroidism. Methods. In a 25-year-old man diagnosed with Down's syndrome, clinical ...
The clinical importance of an undetectable thyroid stimulating hormone (TSH) concentration (less than 0.2 mU/l) was studied in a consecutive series of 2573 requests for routine thyroid function tests. Two hundred and seventeen (8.4%) patients had an undetectable TSH concentration, and of these 39 (18%) had otherwise normal thyroid hormone concentrations and no history of thyroid disease. In a f...
Thyroid hormone resistance (THR) is a dominantly inherited syndrome characterized by reduced sensitivity to thyroid hormones. It is usually caused by mutations in the thyroid hormone receptor beta (THRB) gene. In the present report, we describe the clinical and laboratory characteristics and genetic analysis of patients with a novel THRB gene mutation. The index patient had been misdiagnosed as...
Background: Much research has widely been conducted into thyroid hormones levels following radiotherapy for breast cancer. Consequently, in this study, we evaluated to relate the rate of thyroid hormones levels with the dose distribution among breast cancer patients.Material and Methods: Thirty patients were treated with 4-field breast cancer radiotherapy. The dose volume histograms, the volume...
background: to investigate thyroid function in preeclamptic patients in comparison with normal pregnant women. methods: in this analytical cross-sectional study free thyroxine (t4), and thyroid stimulating hormone (tsh) levels were measured in 100 preeclamptic patients and were compared with free t4 and tsh levels in 101 normal pregnant women in their third trimester of pregnancy. patients with...
