1.Risk factors for neonatal congenital hypothyroidism: a Meta analysis.
Chinese Journal of Contemporary Pediatrics 2021;23(5):505-512
OBJECTIVE:
To investigate the risk factors for congenital hypothyroidism (CH) in neonates, and to provide a reference for the prevention of CH.
METHODS:
The databases including China Biomedical Literature Service System, China National Knowledge Infrastructure, Wanfang Data, and Weipu Periodical Database, PubMed, Web of Science, Embase, SpringerLink, and Elsevier/ScienceDirect were searched for studies on the risk factors for CH in neonates published up to August 1, 2020. R 3.6.2 and RevMan 5.3 software were used to perform a Meta analysis.
RESULTS:
A total of 20 studies were included, with 13 case-control studies and 7 cross-sectional studies. There were 11 564 neonates in total, with 3 579 neonates in the case group and 7 985 neonates in the control group. The Meta analysis showed that advanced maternal age (
CONCLUSIONS
Advanced maternal age, gestational thyroid disease, gestational diabetes mellitus, anxiety, medication during pregnancy, radiation exposure during pregnancy, family history of thyroid disease, low birth weight, fetal macrosomia, preterm birth, post-term birth, twin pregnancy or multiple pregnancy, and birth defects may increase the risk of CH in neonates.

OBJECTIVETo study the effect of maternal Hashimoto's disease (an autoimmune thyroid disease) on intellectual development of infants.
METHODSFrom July 2001 to June 2003, 21 infants born by mothers suffered from Hashimoto's disease were followed up with provincial neonatal disease screening network system. Their thyroid function was assessed and their mental development was evaluated with Gesell development schedules.
RESULT(1) Among the 21 infants, 8 showed normal thyroid function, 11 showed hyperthyrotropinemia, 2 cases had congenital hypothyroidism, which showed significant differences from those born by healthy mothers. (2) The mental and psychomotor development of infants whose mothers suffered from Hashimoto's disease lagged behind those with the healthy mothers (P <0.05).
CONCLUSIONMaternal Hashimoto's disease may affects infants' thyroid function and mental development.

3.Neuro-developmental deficits in early-treated congenital hypothyroidism.
Annals of the Academy of Medicine, Singapore 2008;37(12 Suppl):42-43
This paper summarises the current evidence on neuro-developmental deficits in the early (< 1 month of age) treated congenital hypothyroid and the influencing factors. A literature search revealed only few citations that compared outcome with matched controls. In all but one, the median age of treatment onset was >2 weeks. Mean Global IQ scores are about 10 points lower and remain identifiable in adulthood. Verbal and performance scores are usually similar. Deficits persisting into adolescence and adulthood involve the visuomotor, memory, attention and posture domains. Lower academic performance is common in the early years. Prenatal factors associated with a worse prognosis are aetiology (dysgenesis), low birth weight, associated complications and severity of hypothyroidism. Postnatal factors are age at onset of treatment (>1 month), lower thyroxine dose at onset (<8 mcg/kg/day), late normalisation of thyroid function (>2 weeks after treatment), and a lower socio economic family status. The author proposes the evaluation of a multi centre cohort with a median age of treatment onset <1 week, TSH normalisation by <3 weeks with treatment thyroxine levels maintained in the 3rd quartile for age. The outcome of this cohort should indicate if current targets in management need to be revised.

Van Wyk-Grumbach syndrome (VWGS) is a rare complication of prolonged untreated juvenile hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. A 13-year-old girl visited our outpatient clinic due to menstrual irregularities. She had precocious puberty, pituitary hyperplasia and multiple cystic ovaries in addition to clinical signs of severe congenital hypothyroidism. After the initiation of L-thyroxine therapy, the symptoms were alleviated in a short time. This rare syndrome is easy to be misdiagnosed as pituitary and ovarian tumor. High degree of suspicion and timely diagnosis can prevent unnecessary surgical procedures because the symptoms can be reversed with thyroid hormone supplementation.
