The Natural History of Delayed TSH Elevation in Neonatal Intensive Care (NICU) Newborns

Zung Amnon , Radi Alin , Almashanu Shlomo

Context: Delayed TSH elevation (dTSH) is defined as elevated TSH in the second neonatal screen following normal TSH in the initial screen. The clinical outcome of newborns with dTSH is not entirely elucidated, although several studies have suggested a full recovery in most cases.Objective: We aim to elucidate the natural history of dTSH in a group of neonatal intensive care newborns. In addition, we aim to define clinica...

Characteristics of Delayed TSH Elevation in Neonatal Intensive Care Unit Newborns

Zung Amnon , Yehieli Arie , Almashanu Shlomo

Background: Delayed TSH elevation (dTSH) is defined by normal TSH on the initial neonatal screening followed by elevated TSH on the second screen. Several studies concluded that dTSH is associated with low birth weight (BW) and is mostly transient.Objective and hypotheses: To elucidate clinical characteristics of dTSH in a large cohort of neonatal intensive care unit (NICU) newborns.Method: Clinical data were gathered from a cohort...

Adrenal Crisis in Children with Adrenal Insufficiency: Prevalence and Risk Factors

Eyal Ori , Levin Yair , Oren Asaf , Zung Amnon , Rachmiel Marianna , Landau Zohar , Weintrob Naomi

Objectives: To assess the prevalence and risk factors of Adrenal crisis (AC) events in children with Adrenal insufficiency (AI) and to evaluate the effectiveness of the treatment for preventing AC.Methods: Children diagnosed with AI between 1990 and 2017 and treated with glucocorticoids at four pediatric endocrinology units in Israel were studied. Data were retrieved retrospectively from the patients’ files and they included demographic factors (age...

Monitoring GnRH Analog Treatment in Girls with Central Precocious Puberty: a Comparison of Four Methods

Zung Amnon , Burundukov Ella , Ulman Mira , Glaser Tamar , Chen Malka , Zadik Zvi

Background: The gold standard for adequate hormonal suppression during GnRHa treatment for precocious puberty (PP) is attenuated serum LH levels in response to LHRH stimulation.Objective and hypotheses: We aimed to compare basal and post-GnRHa levels of LH to LHRH stimulation test, and to evaluate first-voided urinary LH (ULH) as a non-invasive alternative method for monitoring treatment.Method: Seventeen girls with PP were followe...

Phenylbutyrate treatment of three patients with Monocarboxylate Transporter 8 deficiency

Zung Amnon , Schreiner Felix , Vollbach Heike , Schweizer Ulrich , Banne Ehud , Braun Doreen

Background: Monocarboxylate transporter 8 (MCT8) deficiency is a rare genetic disease that leads to severe global developmental delay. Thyroid hormone (TH) profile is characterized by high T3 and low T4 levels, with normal or elevated TSH. Recent studies have shown that the chemical chaperone phenylbutyrate (PB) restored mutant MCT8 function and increased TH content in a patient-derived cell model, making it a potential treatment for MCT8 deficiency.<p cla...

Background: GLI2 is a zinc-finger transcription factor of the SHH signaling pathway, expressed during ventral forebrain and pituitary development. GLI2 mutations account for microforms of dominant holoprosencephaly. So far, only 15 unambiguous mutations were found in hypopituitarism –essentially combined pituitary hormone deficiency (CPHD)– frequently associated with holoprosencephaly-like malformations and/or polydactyly.Objective and...

Introduction: Primary ovarian Insufficiency (POI) occurring in youth is a devastating condition. POI is characterized by at least 4 months of disordered menses in association with menopausal follicle stimulating hormone (FSH) levels. The most common causes of POI in adolescence are iatrogenic and chromosomal abnormalities. Data are scarce regarding the incidence of POI in adolescents.Objectives: We aimed to estimate the incidence and the distribution of ...
