INTRODUCTION: Iodine deficiency in pregnancy may impair foetal neurological development. The UK population is generally thought to be iodine sufficient; however, recent studies have questioned this assumption. Our study aimed to explore the prevalence of iodine deficiency in a cohort of pregnant mothers from South-West England. METHODS: Urine samples were obtained from 308 women participating in a study of breech presentation in late pregnancy. They had no known thyroid disease and a singleton pregnancy at 36-38 weeks' gestation...

Type B Coxsackievirus (CV-B) infections are frequently involved in the triggering of several autoimmune diseases such as myocarditis, dilated cardiomyopathy, pericarditis, pancreatitis, type 1 diabetes, encephalitis, thyroiditis, or Sjögren's syndrome. Serological and virological evidence suggests that maternal infections during pregnancy can play a role in the appearance of these diseases in offspring. The current study aims to explore the effect of an in utero CV-B infection on the fetal thymus, the central site for programming immunological self-tolerance...

BACKGROUND: Fetal exposure to a maternal low protein diet during rat pregnancy is associated with hypertension, renal dysfunction and metabolic disturbance in adult life. These effects are present when dietary manipulations target only the first half of pregnancy. It was hypothesised that early gestation protein restriction would impact upon placental gene expression and that this may give clues to the mechanism which links maternal diet to later consequences. METHODS: Pregnant rats were fed control or a low protein diet from conception to day 13 gestation...

BACKGROUND: During gestation, the primordial thymus migrates from the pharynx to the anterior mediastinum, thus thymic tissue can remain at any point along this path. Intrathyroidal thymic remnants are rare, and their sonographic patterns have only recently been described. This retrospective study presents the sonographic appearance of ectopic intrathyroidal thymus and emphasizes the role of sonography in order to avoid misdiagnosis. METHODS: The population consisted of 42 children, 3...

Hyperthyroidism can occur during pregnancy and the postpartum period, and the treatment of hyperthyroidism should be considered in the preconception phase. Pregnancy has multiple normal physiologic effects on thyroid hormone, which is a separate process distinct from syndromes such as transient hyperthyroidism of hyperemesis gravidarum. The rationale regarding antithyroid drug use during different stages of pregnancy is reviewed, including the literature regarding adverse neonatal outcomes such as aplasia cutis and methimazole embryopathy in the setting of first trimester maternal methimazole use...

Antithyroid drugs (ATDs) are widely used for the treatment of Graves' disease (GD) in the general population. Over the past decade, there has been an increasing awareness that several disturbances of thyroid function may occur in mothers after delivery which may be more prevalent than previously appreciated. Exacerbation of immune reactions occurs 3-12 month following delivery. Management of hyperthyroidism during lactation requires special considerations and should be implemented to prevent any adverse outcomes in mother and neonate...

Thyrotoxicosis is a pathological syndrome in which tissue is exposed to excessive amounts of circulating thyroid hormones. Including its subclinical form, it is considered as one of the most frequent endocrine disorders in the general population. If not detected in a timely fashion, thyrotoxicosis can have serious health consequences. The most common forms of thyrotoxicosis include diffuse toxic goiter (Graves' disease), toxic multinodular goiter (Plummer's disease), and toxic adenoma (Goetsch's disease). The significant progress in the fields of hormonal assessment, imaging procedures and molecular biology made in recent years has brought about great improvement in the identification, differentiation and treatment of many other disorders associated with thyrotoxicosis...

We aimed to examine the distribution of 1(st) trimester TSH and evaluate its association with perinatal outcomes and future development of maternal thyrotoxicosis. This retrospective cohort study included data of all women without prior thyroid disease who delivered a singleton at our medical center from 1/2001 to 12/2011 and had a 1(st) trimester TSH<4.0 mU/l. Women were divided according to 1(st) trimester TSH concentrations into quartiles and by predefined TSH values (mU/l): 1) TSH<0.1; 2) TSH 0...

OBJECTIVE: To investigate the relationship between placental transthyretin (TTR) level and preeclampsia. MATERIALS AND METHODS: Placental tissues from uncomplicated and preeclamptic pregnancies were analyzed using immunohistochemistry and image analysis. We measured the mean optical density (OD) of immunohistochemical staining of TTR across multiple sections using Image Pro Plus 6.0. To avoid bias, we used placental tissue array, which contained preeclamptic placentas (n=8) and the control placentas (n=6) on the same slide...

A 29-year-old woman at 34 weeks' gestation with uncontrolled hyperthyroidism and thyrotoxic heart disease was admitted to urgency Cesarean section. After preoperative sedation and good communication, low-dose spinal anesthesia (7.5 mg 0.5 % bupivacaine) combined with epidural anesthesia (6 ml 2 % lidocaine) was performed through L3-4 inter-vertebral. Opioids were given intravenously to the mother for sedation after delivery of the baby. Satisfactory anesthesia and sedation was provided during surgery. The mother and the neonate were safe and no special complication was found after surgery...

Anti-C1q antibodies (anti-C1q) have been implicated in the pathogenesis of autoimmune diseases, including autoimmune thyroid disorders (AITD). The aim of this study was to evaluate the association between anti-C1q and thyroid function in pregnancy-associated AITD. In 96 pregnant women screened positive for AITD (thyroid dysfunction and/or antibodies against thyroperoxidase - TPOAb), anti-C1q were measured during the 9-11th gestational week and after delivery (median 16 months after delivery), and compared to the corresponding serum levels of thyroid hormones...

OBJECTIVE: To identify predictors of transience vs permanence of neonatal hyperthyrotropinemia. We hypothesized that infants with greater severity of perinatal stress are more likely to have transient thyrotropin elevations. STUDY DESIGN: We retrospectively studied infants diagnosed with hyperthyrotropinemia between 2002 and 2014, following them for up to 12 years after diagnosis. Patients were divided into 3 groups: transient hyperthyrotropinemia (treatment was never prescribed), transient congenital hypothyroidism (treatment started but discontinued), and permanent congenital hypothyroidism (withdrawal unsuccessful or not attempted)...

Aging is associated with increased prevalence of cardiovascular disease. Thyroid hormone deficiency during fetal life decreases myocardial tolerance to ischemia-reperfusion (IR) injury in later life. The long-term effects of fetal hypothyroidism (FH) on response to IR injury in aged rats have not been well documented. The aim of this study was therefore to compare the effect of FH on tolerance to IR injury in young and aged male rats and to determine contribution of iNOS (inducible nitric oxide synthase), Bax, and Bcl-2...

BACKGROUND: Congenital hypothyroidism (CH) is caused by thyroid gland (TG) dysgenesis or inadequate thyroid hormone biosynthesis in a structurally normal gland. Different etiologies are known to be associated with various clinical, biochemical and imaging markers and a subset of cases have an underlying genetic basis. Despite the presence of neonatal screening programs in the UAE, there is a lack of data on the disease etiology in the area. We aim to study the etiology of CH in our center and examine its relationship with the clinical, biochemical, genetic and radiological features...

INTRODUCTION: Gestational trophoblastic disease (GTD) encompasses a group of tumors derived from trophoblasts, which normally form the placenta during pregnancy. Human chorionic gonadotropin (hCG) is a glycoprotein composed of an alpha subunit identical to that of thyroid stimulating hormone (TSH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Detection of beta-hCG is achievable in both urine and serum samples, proving useful for the detection of normal pregnancy and GTD...

Babies born small are at an increased risk of developing myriad adult diseases. While growth restriction increases disease risk in all individuals, often a second hit is required to unmask 'programmed' impairments in physiology. Programmed disease outcomes are demonstrated more commonly in male offspring compared with females, with these sex-specific outcomes partly attributed to different placenta-regulated growth strategies of the male and female fetus. Pregnancy is known to be a major risk factor for unmasking a number of conditions and can be considered a 'second hit' for women who were born small...
