Fetal alcohol spectrum disorder (FASD), the result of fetal alcohol exposure (FAE), affects 2-11% of children worldwide, with no effective treatments. Hippocampus-based learning and memory deficits are key symptoms of FASD. Our previous studies show hypothyroxinemia and hyperglycemia of the alcohol-consuming pregnant rat, which likely affects fetal neurodevelopment. We administered vehicle, thyroxine (T4) or metformin to neonatal rats post FAE and rats were tested in the hippocampus-dependent contextual fear-conditioning paradigm in adulthood...

BACKGROUND: Several studies have reported that morbid obesity is associated with increased thyroid-stimulating hormone (TSH) levels. However, it is not clear what is the impact of bariatric surgery on postoperative thyroid function. The aim of this study was to evaluate the effect of weight loss after bariatric surgery on TSH levels in euthyroid patients with morbid obesity. METHODS: We performed a retrospective observational study of 949 euthyroid patients (86...

REVIEW
Małgorzata Gietka-Czernel
The incidence of most thyroid diseases: hypothyroidism, nodular goitre, and cancer is highest among postmenopausal and elderly women. The diagnosis of thyroid dysfunction in this group of patients is difficult because the symptoms can be nonspecific or common with menopausal and ageing complaints. In the interpretation of thyroid function tests the physiological changes in secretion and metabolism of thyrotropin (TSH) and thyroid hormones must be considered, as well as the influence of comorbidities. Unrecognised thyroid dysfunction leads to increased: cardiovascular risk, bone fractures, cognitive impairment, depression, and mortality...

Mercury (Hg) poisoning is considered a rare disease by the National Institutes of Health and the diagnosis can present great challenges to clinicians. Children who are exposed to Hg can present with a wide variety of symptoms, including acrodynia, tremor, excessive salivation, and psychiatric symptoms, including insomnia. However, endocrinologic manifestations from Hg exposure are less well known. This is a case report of a 12-year-old boy who presented with body rash, irritability, insomnia, and profuse sweating after returning from a summer camp...

BACKGROUND: Thyroid-stimulating hormone (TSH) suppression has improved the clinical outcomes of patients with differentiated thyroid cancer (DTC). However, the efficacy of TSH suppressive therapy (TST) is unclear in patients with low-risk DTC. We aimed to evaluate the efficacy of TST and optimal TSH levels of patients with low-risk DTC. METHODS: The retrospective propensity-score matched cohort study included DTC patients (n = 446) who underwent lobectomy from 2002 to 2008 with or without TST (TST group and No-TST group)...

INTRODUCTION: Pituitary hyperplasia due to primary hypothyroidism is rare and underdiagnosed. CASE REPORT: We report an 18-year-old patient referred for a pituitary mass revealing primary hypothyroidism. Biological parameters confirmed severe primary hypothyroidism and hyperprolactinemia. Outcome was favorable with l-thyroxin supplementation resulting in TSH and prolactin levels normalization and pituitary mass resolution. CONCLUSION: Pituitary hyperplasia due to primary hypothyroidism, although rare, should be recognized to avoid unnecessary surgery leading to irreversible complications...

Domesticated horses are increasingly kept under semi-natural housing conditions, whereas their adaptation capacity is not fully investigated. In all, 10 Shetland pony mares were held under semi-extensive conditions for 1 year. In winter animals were allocated into two feeding groups (60% and 100% of maintenance energy requirement, respectively). Triiodothyronine, thyroxine, non-esterified fatty acids (NEFA), total bilirubin, total protein, triglyceride, glucose, insulin and hair length were measured at monthly intervals, whereas BW, body condition score, cresty neck score and resting heart rate were recorded every 2 weeks...

INTRODUCTION: The non-adherence to substitutive treatment by L-thyroxine is the main cause of the discordance between high thyrotropin values and high doses of the drug. OBSERVATION: In a 36-year-old patient with post-surgery hypothyroidism, thyrotropin values ranged between 100 and 400 mUI/L, although daily replacement therapy included 300 μg of L-thyroxine and 75 μg of L-triiodothyronine. The oral loading test with L-thyroxine was normal and thyrotropin serum level returned to normal values under weekly oral administration of 1000 μg L-thyroxine...

Decabromodiphenyl ether (BDE-209) was one of most widely-used polybrominated diphenyl ether (PBDE) flame retardants and is frequently detected in both abiotic and biotic samples from environment. However, knowledge of its transgenerational risks is limited. Here, 4-month-old zebrafish were exposed to various concentrations of BDE-209 (0, 3, 30 or 300μg/L) for 28days and spawned in clean water without BDE-209. Concentrations of triiodothyronine (T3) and thyroxine (T4) as well as expressions of genes involved in the hypothalamic-pituitary-thyroid (HPT) axis were measured in offspring after exposure of adult zebrafish to BDE-209...

BACKGROUND: Anti-thyroid drug therapy is considered a treatment of choice for Graves' disease; however, treatment response varies among individuals. Although several studies have reported risk factors for relapse after initial treatment, few have assessed responsiveness during the early treatment period. Our study aimed to identify the clinical characteristics for responsiveness to methimazole. METHODS: We included 99 patients diagnosed with Graves' disease for the first time...

BACKGROUND: The prevalence of latent/subclinical hypothyroidism is between 3% and 10%, according to epidemiologic studies that have been carried out in the USA, the United Kingdom, and Denmark. As persons with latent hypo - thyroidism are often asymptomatic, the diagnosis is often made incidentally in routine laboratory testing. METHODS: This review is based on a selective search in PubMed for publications on the diagnosis and treatment of latent hypothyroidism...

BACKGROUND: Studies show that a significant portion of laboratory testing is unnecessary. Thyroid tests are some of the most commonly ordered laboratory tests, yet little is known about practice patterns for laboratory testing for thyroid disease. The objective of this study was to collect data on practice patterns for thyroid testing in the United States. METHODS: A survey was conducted to collect data on annual test volumes for thyroid stimulating hormone (TSH), free thyroxine (FT4), total thyroxine (TT4), free triiodothyronine (FT3), total triiodothyronine (TT3), triiodothyronine uptake (T3U), reverse triiodothyronine (rT3), and complete blood counts (CBC)...

Subclinical hyperthyroidism is defined by a low or undetectable serum thyroid-stimulating hormone level, with normal free thyroxine and total or free triiodothyronine levels. It can be caused by increased endogenous production of thyroid hormone (e.g., in Graves disease, toxic nodular goiter, or transient thyroiditis), by administration of thyroid hormone to treat malignant thyroid disease, or by unintentional excessive replacement therapy. The prevalence of subclinical hyperthyroidism in the general population is about 1% to 2%; however, it may be higher in iodinedeficient areas...

Context: Thyroid hemiagenesis (THA) constitutes a rare, congenital disorder that is characterized by an absence of one thyroid lobe. Because the pathogenesis and clinical significance of this malformation remain undefined, specific clinical recommendations are lacking, especially for asymptomatic cases. Evidence Acquisition: The PubMed Database was searched (years 1970-2017) and the following terms were used to retrieve the results: "thyroid hemiagenesis", "thyroid hemiaplasia", "one thyroid lobe agenesis" and "one thyroid lobe aplasia"...

BACKGROUND: Changes in thyroid function following bariatric surgery in euthyroid obese patients have yielded inconsistent results. Nevertheless, no data exist on changes in thyroid function after bariatric surgery in Chinese obese subjects. OBJECTIVES: The objective of this study is to evaluate the influence of weight reduction on thyroid function following laparoscopic sleeve gastrectomy (LSG) in patients with normal thyroid function. PATIENTS AND METHODS: Serum free thyroxine (FT4), free triiodothyronine (FT3), and thyroid-stimulating hormone (TSH) levels were retrospectively analyzed before and 12 months after LSG in euthyroid patients with morbid obesity...
