Objective: Thyroid disorder is a common endocrine complication in pregnant women: the association between neonatal low birth weight (LBW) and thyroid dysfunction during pregnancy has not been definitely confirmed. We conduct a systematic literature review and meta-analysis of the adverse fetal complication of LBW in maternal thyroid disease, including overt and subclinical hyperthyroidism and h...

OBJECTIVES To examine the risk of atrial fibrillation in relation to the whole spectrum of thyroid function in a large cohort of patients. DESIGN Population based cohort study of general practice patients identified by linkage of nationwide registries at the individual level. SETTING Primary care patients in the city of Copenhagen. SUBJECTS Registry data for 586,460 adults who had their t...

INTRODUCTION AND AIM About 15% of hyperthyroid patients suffer from gastrointestinal symptoms such as diarrhea, constipation, nausea and early satiety the problem. Published reports on the topic of gastric emptying in hyperthyroidism are rare and discrepant in their results. PATIENTS AND METHODS Thirteen patients (8 women, 5 male; aged 41.92+/-1.491 SE yr) with a recently established diagnosi...

Thyroid dysfunction is one of the most commonly encountered endocrine abnormalities. The screening of thyroid dysfunction is recommended in Nepal with its high risk population. Many factors are responsible for exacerbating the thyroid dysfunction in the context of Nepal. Therefore, this study was designed to assess the prevalence of thyroid dysfunction in Dhulikhel Hospital-Kathmandu University...

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...

INTRODUCTION Non-specific abnormalities in liver function tests might accompany the clinical course of hyperthyroidism. Hyperthyroidism can cause the elevation of hepatic enzymes and bilirubin. Jaundice is rare in overt hyperthyroidism, especially in subclinical hyperthyroidism. On the other hand, the use of anti-thyroid drugs has rarely been associated with toxic hepatitis and cholestatic jaun...

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...

OBJECTIVES Numerous studies have reported the effects of subclinical hyperthyroidism on the cardiovascular system, osteoporosis, and metabolic syndrome. However, there are few studies examining the relationships between subclinical hyperthyroidism and thyroid cancer. The aim of this study was to investigate the relationships between preoperative subclinical hyperthyroidism and clinicopathologic...

Subclinical hyperthyroidism appears to be a common disorder. It may be caused by exogenous or endogenous factors: excessive TSH suppressive therapy with L-thyroxine (L-T4) for benign thyroid nodular disease, differentiated thyroid cancer, or hormone over-replacement in patients with hypothyroidism are the most frequent causes. Consistent evidence indicates that 'subclinical' hyperthyroidism red...

Clinical aspects, laboratory investigation, and treatment of hyperthyroidism and hypothyroidism are reviewed in light of recent information. Special circumstances, such as hyperthyroidism during pregnancy, Graves ophthalmopathy, iodine-induced hyperthyroidism, and subclinical hypothyroidism, are also considered.
