Widespread use of improved measurements for serum thyroid hormones and thyroid-stimulating hormone (TSH) has resulted in characterization of the syndromes of subclinical hypothyroidism, characterized by normal free T4 estimate and raised serum TSH, and subclinical hyperthyroidism, in which patients have normal serum free T4 estimate and decreased serum TSH. Therapy for these two disorders in ge...

OBJECTIVE To establish relationship between obesity and hypothyroidism and to analyze the frequency the frequency of primary hypothyroidism in obese patients and frequency of obesity in primary hypothyroidism patients. METHODS We conducted this retrospective, observational study in the Department of Endocrinology and Obesity Clinic, Medwin Hospital, Hyderabad, India in Mar 2008. In the last 1...

Advances in thyroid disorder diagnosis have created new thyroid disorder categories such as subclinical hyperthyroidism and subclinical hypothyroidism. In the 1980s, immunometric assaying for thyroid stimulating hormone (TSH) emerged and became defined as the most cost-effective test in thyroid disorder screening. The second step in the screening of thyroid disorders is to determine free thyrox...

Subclinical hypothyroidism was detected in 5.7% of 853 patients referred for ambulatory examination to a department in Prague. In patients referred with a mild degree of subclinical hypothyroidism with an evaluated level of thyrotropic hormone in serum (TSH) no significant deviations of serum thyroxine and triiodothyronine (T4 and T3) were found nor different values of the Achilles tendon refle...

Background It is well documented that overt hypothyroidism is associated with adverse pregnancy outcomes, but studies of subclinical hypothyroidism have demonstrated conflicting results. Objective Thyroid hormones are known to regulate mitochondrial function, and the aim of this study was to examine the possible relationship of subclinical hypothyroidism and mitochondrial dysfunction to adver...

Subclinical hypothyroidism and hyperthyroidism are diagnoses based on laboratory evaluation with few if any clinical signs or symptoms. Subclinical hypothyroidism is defined as an elevation in serum thyroid-stimulating hormone (TSH) above the upper limit of the reference range (0.45-4.5 mIU/L) with normal serum FT4 concentration; subclinical hyperthyroidism is defined as a decrease in serum TSH...

Purpose: To analyze whether the thyroid status is affecting in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. Methods: In this retrospective cohort study, we reviewed the medical records of 426 infertile women who underwent IVF/ICSI cycles. Included were hypothyroid (HypoT-LT4) patients with serum thyroidstimulating hormone (TSH) concentrations > 4.0 μIU/mL, which wer...

Subclinical hypothyroidism, defined as a mild degree of thyroid dysfunction biochemically, is a common clinical disease. It is marked by elevated serum concentrations of thyroid stim‐ ulating hormone (TSH) and normal serum concentrations of free thyroxine (fT4) and triiodo‐ thyronine (T3). Subclinical hypothyroidism can be divided into two categories, depending on the magnitude of the increase ...

The current controversy over recommendations for thyroid screening during pregnancy has its origins in the 1999 publication of an observational study based on thyroid function analysis of stored secondtrimester serum samples. In this study, 62 children of mothers identified with thyroid-stimulating hormone (TSH) levels greater than the 98th percentile were compared with 124 children of euthyroi...

background: studies demonstrated controversial results on subclinical hypothyroidism (sch) regarding lipid profile alteration with or without levothyroxine treatment. the purpose of this study is to investigate the effects of levothyroxine on serum lipids in sch. materials and methods: one hundred patients with sch referred to taleghani hospital in kermanshah were recruited and randomly assigne...
