Antemortem Chemical Hypothyroxinemia
Journal of Forensic Sciences, 1983Abstract Based on reports of hypothyroidism in intensive care unit patients, a preliminary study was instituted in which 40 patients coming to autopsy, with no history of thyroid disease, were studied to include gross and microscopic study of the thyroid gland and the performance of thyroid function tests on all serum specimens submitted

Transient hypothyroxinemia of prematurity and histological chorioamnionitis
Journal of Perinatal Medicine, 2005Transient hypothyroxinaemia of prematurity (THOP) is a common condition of preterm infants whose causes remain unclear. We tested the hypothesis that THOP is associated with histological chorioamnionitis (HCA).Whole blood T4 and TSH concentrations on day 4 and at 40 weeks' postmenstrual age (rtx-T4 and rtx-TSH), placental histology and illness severity

Gestational hypothyroxinemia and cognitive function in offspring
Neuroscience and Behavioral Physiology, 2006The effects of gestational hypothyroxinemia on the neurointellectual prognosis of children in the first year of life living in an industrial city (megalopolis) with mild iodine deficiency were studied in 13 children of mothers with thyroid hormone-corrected gestational hypothyroxinemia in the first trimester and 10 children of mothers with normal ...

Hypothyroxinemia and Phenytoin Toxicity: A Vicious Circle
Drug Metabolism and Drug Interactions, 1996Phenytoin is a widely used anticonvulsant which has a relatively narrow therapeutic range of serum concentrations, 40-80 mmol/l (10-20 mg/l). Phenytoin is known to show concentration-dependent kinetics within this therapeutic range. Because of this, small changes in dose and minor alterations in hepatic metabolism of phenytoin may cause a ...

Perfluorinated acids and hypothyroxinemia in pregnant women
Environmental Research, 2011Perfluorinated acids (PFAs) are prominent and widespread contaminants of human blood. In animal studies there is evidence that suggests certain PFAs can disrupt thyroid hormone homeostasis. A commonly reported condition in exposed animals is hypothyroxinemia, whereby serum free thyroxine (fT4) is decreased despite normal thyroid stimulating hormone ...

Hypothyroxinemia and Risk for Transient Tachypnea of Newborn
The Journal of Pediatrics, 2016Transient tachypnea of newborn is associated with hypothyroxinemia in animals via decreased stimulation of beta-adrenergic receptors and Na-K-ATPase activity. In 26 549 term neonates, serum total thyroxine

Subclinical Hypothyroidism and Hypothyroxinemia in Pregnancy — Still No Answers
New England Journal of Medicine, 2017Transplacental passage of maternal thyroxine (T4) is essential for the maintenance of pregnancy and for normal fetal development, especially in the first half of gestation. Mild or subclinical hypothyroidism in pregnancy has been linked to adverse outcomes, including miscarriage, preterm delivery, low birth weight, and lower-than-normal IQ in offspring,
