Hypothyroxinemia and weight velocity in preterm infants
Journal of Pediatric Endocrinology and MetabolismAbstract Objectives Hypothyroxinemia of prematurity (HOP) is characterized by low free thyroxine (FT4) associated with low or normal thyroid stimulating hormone (TSH). The objective of this study is to define FT4 and TSH values in very preterm infants (<32 weeks postmenstrual age, PMA) and ...

The Impact of Isolated Maternal Hypothyroxinemia on Perinatal Morbidity
Journal of Obstetrics and Gynaecology Canada, 2009To determine whether maternal hypothyroxinemia during early pregnancy is associated with adverse perinatal outcomes.Serum samples of a prospective cohort of 879 women collected at 15-16 weeks of pregnancy were analyzed for thyroid-stimulating hormone (TSH) and free thyroxine (T4) concentrations.

Maternal Hypothyroxinemia-Induced Neurodevelopmental Impairments in the Progeny
Molecular Neurobiology, 2015Maternal hypothyroxinemia can induce neurodevelopmental impairments in the developing fetus. We here review recent studies on the epidemiology and molecular mechanisms associated with this important public health issue. In 2011, the American Thyroid Association defined maternal hypothyroxinemia as low serum free thyroxine (FT4) levels (

Acute keratoconus induced by hypothyroxinemia during pregnancy
Journal of Endocrinological Investigation, 2008Keratoconus is a bilateral non-inflammatory corneal ectasia with an incidence of approximately 1 per 2000 in the general population. The etiology of keratoconus is multifactorial, although not completely understood. Several clinical observations suggest that thyroid gland dysfunction is associated with keratoconus pathophysiology.

Hypothyroxinemia in Premature Infants: Is Thyroxine Treatment Necessary?
Thyroid, 1999The increased survival of very low birth weight (VLBW) premature infants has been associated with an increased prevalence of transient disorders of thyroid function during the early weeks of life. All VLBW infants have relatively low, and gestation age-dependent, thyroxine-binding globulin (TBG) concentrations associated with variably low total ...

Thyroid Function in Premature Infants: The Hypothyroxinemia of Prematurity
Clinics in Perinatology, 1998Advances of perinatal and neonatal medicine have been associated with a progressive reduction in mortality of premature infants and a progressive increase in number of the surviving very low birth weight (VLBW) cohort less than 28 to 32 weeks gestation age. Hypothalamic-pituitary-thyroid (HPT) function is immature in most premature infants, and this is

The diagnostic dilemmas of hyperthyroxinemia and hypothyroxinemia.
Advances in internal medicine, 1988It should be apparent that the diagnosis of thyrotoxicosis and hypothyroidism can be correctly made in the majority of ambulatory patients. However, the clinician needs to be extremely careful in reaching such a definitive diagnosis on the hospitalized patient.
