Nine normal volunteers and 15 patients with pituitary disorders were given a combined test of anterior pituitary function using four hypothalamic releasing factors and arginine vasopressin. Rapid sequential intravenous infusions of human corticotrophin releasing factor 100 micrograms, growth hormone releasing factor 100 micrograms, luteinising hormone releasing hormone 100 micrograms, and thyro...
Autoimmune thyroiditis is one of the most common causes acquired hypothyroidism in children and adolescents. Both genetic susceptibility environmental factors play a role etiopathogenesis. We report two cases autoimmune here with varied presentation. them had different clinical features at On investigation, both elevated thyroid-stimulating hormone (TSH), low T4 anti-Thyroid peroxidase (TPO) an...
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...
Recent evidence indicates that thyroid hormones may be closely linked to cognition among adults. We investigated associations between thyroid hormones and longitudinal cognitive change, within and outside of reference ranges, stratifying by sex and race. This longitudinal study used data from the Healthy Aging in Neighborhoods of Diversity Across the Lifespan study, set in Baltimore City, MD, 2...
The optimum daily dose of thyroxine was calculated for 13 children aged 3-16 years with primary hypothyroidism by titrating their doses at monthly intervals. The condition of the thyroid was assessed by sensitive assay of thyroid stimulating hormone concentrations, as well as measurement of total and free thyroid hormone concentrations and systolic time interval ratios. Serum thyroid stimulatin...
Assessments were made of 945 consecutive hospital patients with regard to a relation between borderline low thyroid function (recognised by a slightly raised thyroid stimulating hormone), thyroid autoimmunity, serum cholesterol, and coronary heart disease. Men and women with a thyroid autoimmunity, serum cholesterol, and coronary heart disease. Men and women with a thyroid stimulating hormone o...
Thyroid dysfunction has been implicated as a cause of reversible cognitive impairment and as such, the thyroid stimulating hormone has long been part of the screening laboratory test for dementia. Recently, several population-based studies demonstrated an association between hypo- or hyperthyroidism and Alzheimer's disease. This review discusses the role of thyroid hormone in the normal develop...
Background: Each toxic agent results in unique presentations, depending on what neurophysiological changes occur following exposure. Scientific understanding of lead toxicity in the organ systems and at low levels of exposure continues to evolve. However, effects of lead poisoning on the thyroid gland function are controversial. In this descriptive study, changes in thyroid hormones in patients...
PURPOSE Thyroid dysfunction is common, particularly among older women. The safety of thyroid hormone use and long-term prognosis of hyperthyroidism remain controversial. We performed a prospective cohort study to examine the relationship among thyroid hormone use, previous hyperthyroidism, abnormal thyroid function, and mortality. METHODS We studied 9449 community-dwelling white women aged > ...
Formaldehyde (HCHO) exposure in industry causes health impairment, especially immune profile. Male albino rats when exposed to HCHO at 5, 10, 15 mg/kg day for 30 days showed decrease in thyroid weight in 10, 15 mg/kg/day HCHO fed group with commensurate follicular regression (epithelial cells), decreased triiodothyronine (T3), thyroxin (T4) deficiency and enhanced thyroid stimulating hormone (T...
