introduction: jaundice is one of the hospitalization causes in term and preterm infants. considering to the side effects of jaundice, the present study aimed to investigate the prevalence and risk factors associated with jaundice in neonates hospitalized in government hospitals in ilam. materials and methods: in a case - control study, 384 neonates were enrolled. all neonates hospitalized in mu...

Thyroid hormone is crucial for growth and hence the current study is designed to correlate the cord blood thyroid stimulating hormone (TSH) levels with their anthropometry and maternal factors in 187 newborns. Statistical analysis was done by Mann Whitney-U test and Spearman correlation coefficient. TSH levels were significantly higher in males than in female newborns (P=0.018). Low birth weigh...

AIMS To assess the association between prenatal exposure to organochlorine compounds and thyroid status in newborns from an area with high levels of hexachlorobenzene (HCB). METHODS A total of 98 mother-infant pairs (83.1% of all children born during the period 1997-99 in a specific area polluted with HCB) were recruited. Levels of organochlorine compounds were measured in 70 cord serum sampl...

OBJECTIVE Iodine deficiency and excess are the most important factors that affect screening and recall rates of congenital hypothyroidism. The purpose of this study was to investigate the urinary iodine status in newborns and their mothers and its effects on neonatal thyroid-stimulating hormone (TSH) levels in a mildly iodine-deficient area. METHODS A total of 116 newborns and their mothers w...

OBJECTIVE To evaluate the incidence of congenital hypothyroidism (CH) with delayed TSH elevation among low-birth-weight (LBW) newborns in North-Eastern Italy and to verify if they need a second or third screening. DESIGN Analysis of clinical and biochemical data of newborns affected by CH with delayed TSH elevation identified by neonatal screening. METHODS Data of all newborns with birth we...

PURPOSE This study was to evaluate the effect of neonatal, maternal, and delivery factors on neonatal thyroid-stimulating hormone (TSH) of healthy newborns. METHODS Medical records of 705 healthy infants born through normal vaginal delivery were reviewed. Neonatal TSH levels obtained by neonatal screening tests were analyzed in relation to perinatal factors and any associations with free thyr...

A study of newborn thyroid stimulating hormone (TSH) levels was undertaken to determine whether a quantitative relationship exists between TSH values obtained between the 12th to 24th hours of life and the 48th to 72nd hours of life. The study was designed to: (a) measure TSH levels in full term newborns between the 12th - 24th hours of life, (b) measure TSH levels in the same set of newborns a...

Purpose: The aim of this study was to evaluate the relationship between thyroid hormone levels and clinical outcomes in preterm, small for gestational age (SGA) infants.
 Materials Methods: premature newborns (gestational ≤30 weeks) were divided into two groups as SGA non-SGA. Thyroid stimulating (TSH) free thyroxine (fT4) levels, frequency congenital hypothyroidism (CH), demographic chara...

Perchlorate (ClO4-) has been detected in groundwater sources in numerous communities in California and other parts of the United States, raising concerns about potential impacts on health. For California communities where ClO4- was tested in 1997 and 1998, we evaluated the prevalence of primary congenital hypothyroidism (PCH) and high thyroid-stimulating hormone (TSH) levels among the 342,257 C...
