Abstract Neonatal thyrotoxicosis is mostly caused by the transplacental passage of maternal thyroid stimulating hormone (TSH) receptor antibodies (TRAb) to fetus. Although rare and transient, this condition may be associated with significant morbidity mortality if not diagnosed treated in an appropriate timely manner. Anti-thyroid drugs are main therapy. Here, we report a preterm newborn that p...

Background: Smoking can cause thyroid disorders; the aim of the present study was to investigate the association between smoking status and changes in thyroid hormone levels among adult males during a decade long follow-up of in the Tehran Thyroid Study (TTS). Methods: Data of 895 adult males (smokers=115, non-smokers=691, ex-smokers=89) participants of the TTS without any previously known thy...

Background: Although there is little information about the prevalence of thyroid disorders in young women, but they are common Iraq. Objective: To hormones test abnormality females at reproductive age attending al-batool maternity teaching hospital Patients and Methods: This study involved 1570 female ages patients Al-batool Maternity Hospital Diyala Province, Serum levels T3, T4, TSH were meas...

Currently, the position of the American Thyroid Association is that hypothyroidism causes symptoms of metabolic slowing due to inadequate production of thyroid hormone by the thyroid gland; it is diagnosed by a lab result of a high thyroid stimulating hormone (TSH) level. While hypothyroidism is considered a chronic, incurable condition, the symptoms typically can be controlled by ingestion of ...

Seventy-eight clinically euthyroid patients with atrial dysrhythmias, either established or paroxysmal, and sixty-three patients in sinus rhythm with coronary disease were screened for hyperthyroidism using thyroid function tests including the thyroid-stimulating hormone (TSH) response to thyrotrophin-releasing hormone (TRH). All had normal levels of serum thyroxine (T4) apart from three with d...

background and aims: 25-hydroxy vitamin d3 is recognized to be an essential element for healthy body; however, its deficiency has been identified as a risk factor for thyroid disease, diabetes mellitus and other autoimmune diseases and infectious diseases. thyroid disease is common in the general population that its prevalence increases proportional to age. subjects with poorly controlled diabe...

Thyroid hormones play essential roles in mammalian life, especially in neurodevelopment (Porterfield & Hendrich, 1993). This fact is clearly shown in patients with neurological deficits from endemic cretinism, who reside in iodine-deficient areas (DeLong et at., 1985). In addition to neurological impairments, thyroid dysfunctions, such as hyperthyroidism and hypothyroidism, lead to a wide varie...

BACKGROUND Biochemical evidence of hyperthyroidism may be associated with low bone mass, particularly in older postmenopausal women, but no prospective studies of thyroid function and subsequent fracture risk have been done. OBJECTIVE To examine the association between low levels of thyroid-stimulating hormone (TSH) and fracture in older women. DESIGN Prospective cohort study with case-coho...

Physiological production of thyroid hormone requires an intact hypothalamic-pituitary-thyroid (HPT) axis and involves thyroid-stimulating hormone (TSH, or thyrotropin) released from the anterior pituitary gland. TSH stimulates thyroid follicular cells to synthesize, store and release the thyroid hormones thyroxine (T4) and triiodothyronine (T3) [1]. Chemical laboratory testing of thyroid functi...

BACKGROUND High serum thyroid-stimulating hormone (TSH) is associated with thyroid carcinoma in patients with thyroid nodules. However, previous studies suggests that TSH is not involved in the pathogenesis of small thyroid carcinomas. We performed this study to evaluate serum TSH as a malignancy predictor in the assessment of small thyroid nodules. METHODS We retrospectively analyzed 3791 pa...
