Objective: The primary aim of this study was the early detection and treatment of hypothyroidism in neonates. This paper describes the determination of cord blood serum T4 and TSH levels, their mean levels, reference ranges and interrelationship. Design: Retrospective analysis of serum T4 and TSH levels in 1153 cord blood samples collected and analyzed during July 1998 to June 2000. Setting: Ce...
BACKGROUND Congenital isolated thyrotropin (TSH) deficiency is an unusual condition characterized by low levels of thyroid hormones and TSH, usually presenting early typical signs of severe hypothyroidism. Five different beta-TSH mutations have been described so far. While 4 of them affect only consanguineous families, a frameshift mutation in exon 3 (C105fs114X) has been found also in nonconsa...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
BACKGROUND In thyroid-stimulating-hormone (TSH)-based newborn congenital hypothyroidism (CH) screening programs, the optimal screening-TSH cutoff level is critical to ensuring that true cases of CH are not missed. Screening-TSH results can also be used to predict the likelihood of CH and guide appropriate clinical management. The purpose of this study is to evaluate the predictive value of vari...
Background and purpose: Âlthough congenital hypothyroidism is a preventable cause of mental disabilities, less than 10% of newborns are diagnosed based on clinical symptoms in the first month. Ïf the diagnosis is not made based on screening programs, it would be delayed and irrepairable cerebral and auditory complications will occur. The purpose of this study was to determine the prevalence of ...
Four epidemiological studies have shown a negative association between prenatal acrylamide exposure and birth size. In order to shed light on the possible underlying mechanism(s), we analysed associations biomarkers related fetal growth. newborns of ENVIRONAGE cohort (n ranges from 215 434), investigated (acrylamide glycidamide hemoglobin adduct levels in cord blood) thyroid hormones (TSH, T3, ...
The aim of this study is to examine the association between transplacental exposure to dioxins/polychlorinated biphenyls (PCBs) and thyroid and growth hormones in newborns. We recruited 118 pregnant women, between 25 and 34 years of age, at the obstetric clinic. Personal data collected included reproductive and medical histories and physical factors. Clinicians gathered placental and umbilical ...
Background and Aim: Congenital hypothyroidism is one of the most common preventable causes of mental retardation in the world the irreversible complications of which can be prevented with timely diagnosis and treatment by the fourth week. This study determined the prevalence of risk of congenital hypothyroidism in Torbat-E-Heydarieh. Material and Methods: In this cross-sectional study ...
Although the Philippines is considered an iodine-deficient country, there are no documented iodine deficiency disorders (IDD) among newborns screened to be positive for congenital hypothyroidism. The objectives of this pilot study were: (1) to determine the levels of urinary iodide (UI) in normal term newborns and their mothers, and (2) to correlate the UI levels of newborns with that of their ...
Prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) evokes extensive concerns regarding public health. Monitoring the pregnant women's can be considered a suitable alternative assess fetus's exposure. This study aimed monitor (n = 126) PAHs using biomonitoring approach evaluate effects on anthropometric indices and neonatal thyroid-stimulating hormone (TSH) in Shiraz, Iran. priority co...
