Jin Yang, Yang Liu, Hongjie Liu, Heming Zheng, Xiaofeng Li, Lin Zhu, Zhe Wang
OBJECTIVE: The study aimed to explore the effects of maternal iodine status and thyroid diseases on adverse pregnancy outcomes. METHODS: A prospective study was conducted on 2347 pregnant women, who provided 2347 urinary samples tested for iodine, 1082 serum samples tested for thyroid function, and 2347 questionnaires about demographic information.

Background: Small cross-sectional studies are published on the trimester-specific normal ranges of thyrotropin and thyroxine levels in Indian women from various parts of the country. Objective: We sought to review the published literature on thyroid function tests in normal pregnant Indian women to see if the pooled data from various studies can define normative data and hypothyroidism in pregnancy. Methods: We retrieved 56 studies from online databases with detailed search using multiple search terms...

INTRODUCTION: Approximately 3% to 5% of pregnant women have hypothyroidism. Despite the potential impact of untreated hypothyroidism on infant neurodevelopment, few studies have investigated the risk factors associated with discontinuation of thyroid hormone replacement therapy (THRT) in pregnancy. We aimed to identify such factors in a population of women using THRT prior to pregnancy. MATERIAL AND METHODS: Data from the Norwegian Mother and Child Cohort Study were linked to records in the Medical Birth Registry of Norway...

BACKGROUND: Spontaneous abortions are the most common complication of pregnancy. Clotrimazole and miconazole are widely used vaginal-anti-mycotic agents used for the treatment of vulvovaginal candidiasis. A previous study has suggested an increased risk of miscarriage associated with these azoles, which may lead health professionals to refrain from their use even if clinically indicated. The aim of the current study was to assess the risk for spontaneous abortions following first trimester exposure to vaginal-anti-mycotics...

OBJECTIVE: Maternal thyroid dysfunction during pregnancy is associated with neurodevelopmental impairment in the offspring. No data are currently available for the offspring of patients treated early for congenital hypothyroidism(CH). The aim of this study was to investigate motor and language milestones at one year of age in a population-based registry of children born to young women with CH. DESIGN AND METHODS: We assessed 110 children born to mothers with CH, and 1367 children from the EDEN French population-based birth cohort study prospectively, at the age of one year, with identical questionnaires...

Norway has been considered iodine replete for decades; however, recent studies indicate reemergence of inadequate iodine status in different population groups. We assessed iodine status in pregnant women based on urinary iodine concentration (UIC), urinary iodine excretion (UIE), and iodine intake from food and supplements. In 804 pregnant women, 24-h iodine intakes from iodine-rich foods and iodine-containing supplements were calculated. In 777 women, iodine concentration was measured in spot urine samples by inductively coupled plasma/mass spectrometry (ICP-MS)...

BACKGROUND: Neonatal hyperthyroidism is rare, seen in infants of mothers with Graves' disease (GD), with transplacental transfer of thyroid-stimulating hormone receptor (TSHR) antibodies (TRAbs). We describe a neonate with severe hyperthyroidism due to TRAbs, born to a mother with autoimmune hypothyroidism. CASE PRESENTATION: A baby boy born preterm at 35 weeks had irritability, tachycardia and proptosis after birth. The mother had autoimmune hypothyroidism, from age 10, with thyroxine replacement and normal thyroid function throughout her pregnancy...

NEW FINDINGS: What is the central question of this study? Does fetal hypothyroidism in rats alter uterine contractions and structure in the adult offspring? What is the main finding and its importance? Our study indicated that maternal hypothyroidism during pregnancy increased gestational length and decreased litter size as well as delayed puberty onset; in addition, maternal hypothyroidism caused irregular uterine contractions and histological changes in the uterus in the female offspring...

Dermatofibromas are benign, fibrohistiocytic, dermal tumors. Solitary dermatofibromas may be incidental findings, whereas multiple dermatofibromas may be associated with systemic conditions or previous therapies. Two women and one man with multiple dermatofibromas and an associated systemic condition, immunosuppression, or both, are described. Nine dermatofibromas developed in a woman with hypothyroidism, optic neuritis, and Arnold Chiari I malformation. Five dermatofibromas developed in a woman with breast cancer who had received several systemic antineoplastic therapies...

OBJECTIVE: An association of pregnancy outcomes with subclinical hypothyroidism has been reported, however there still exists a strong controversy regarding whether subclinical hypothyroidism ought to be dealt with or not. The objective of the study was to evaluate the association of fetal-maternal complications with first trimester maternal TSH values. DESIGN: A retrospective study in a single tertiary care hospital was performed. PATIENTS: 1981 pregnant women were studied during 2012...

PURPOSE: This study aimed to systematically evaluate the quality of guidelines for the management of hypothyroidism in pregnancy. METHOD: Systematic searches were conducted to identify hypothyroidism in pregnancy guidelines published in electronic databases and developers' websites. Four reviewers independently evaluated eligible guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Agreement among reviewers was measured using the intraclass correlation coefficient (ICC)...

There is currently no consensus among the different scientific societies on screening for thyroid dysfunction in the first trimester of pregnancy. Indeed, diagnosis and treatment of subclinical hypothyroidism during pregnancy are controversial, as no cut-off value for thyrotropin (TSH) is universally accepted. TSH measurement may be influenced by different factors throughout pregnancy, but especially during the first trimester. The association between overt hypothyroidism during pregnancy and obstetric and perinatal complications is well established...

BACKGROUND AND OBJECTIVE: Infertility is a common disease that in about one third of cases has a female cause and often requires assisted reproduction technologies (ART) to conceive. Also thyroid autoimmunity (TAI), with or without hypothyroidism, is a common disease, particularly in females, and referral for endocrine consultation is not infrequent. DISCUSSION: In the last 15 years a remarkable amount of studies has been published that investigated the pathophysiology of women suffering from TAI, who undergo ART...

Thyroid hormone (TH) is crucial for brain development and function. This becomes most evident in untreated congenital hypothyroidism, leading to irreversible mental retardation. Likewise, maternal hypothyroxinemia, a lack of TH during pregnancy, is associated with neurological dysfunction in the offspring such as autism and reduced intellectual capacity. In the brain, TH acts mainly through TH receptor alpha 1 (TRα1). Consequently, mice heterozygous for a dominant-negative mutation in TRα1 display profound neuroanatomical abnormalities including deranged development of parvalbumin neurons...
