Analysis of a large panel of genes in a cohort of patients with severe short stature: detection rate and genotype-phenotype correlations

Guazzarotti Laura , Mozzato Chiara , Meneghin Alice , Nicolucci Antonio , Cassina Matteo

Short stature is a frequent reason for referral to pediatric endocrinologists and this phenotype has been associated with a large number of gene variations during the last decades, highlighting its complex and heterogeneous etiology. We evaluated the detection rate of the analysis of a selected gene panel in a cohort of patients with short stature defined as height below -2 standard deviations (SD). Overall, 134 patients were included in the study: 73 with GH deficiency (GHD),...

Prenatal AnoGenital Distance (AGD) by ultrasonography in 571 fetuses and correlation to postnatal AGD: A longitudinal cohort study of healthy males and females

Bistrup Fischer Margit , Mola Gylli , Scheel Lone , Kristine Hegaard Hanne , Sundberg Karin , Juul Anders , P Hagen Casper

Background: The anogenital distance (AGD) is a well-known measure in rodents used to distinguish male and female pubs. Likewise, AGD display sex-specific differences in humans. It is considered a postnatal readout of early androgen exposure in fetal life. Thus, in postnatal life AGD is longer in boys than in girls, reduced in infants born with cryptorchidism and hypospadias as well as in boys exposed to anti-androgenic agents in fetal life. However, little is ...

Severe neonatal hypoglycemia ≤30 mg/dl is associated with adverse neurodevelopment in mid-childhood

Roeper Marcia , Hoermann Henrike , Koerner Lisa , Mayatepek Ertan , Kummer Sebastian , Meissner Thomas

Introduction: Neonatal hypoglycemia (NH) affects about 15% of all neonates and about 50% of neonates born with risk factors, including maternal diabetes, large- or small for gestational age, or prematurity. Although it is known that hypoglycemia in congenital hyperinsulinism can lead to brain injury, it is still not clear to what extent transitional NH is tolerated during the first days of life without brain damage. Thus, treatment thresholds and management st...

Analysis of Pubertal Height Gain after Menarchal girls in Korea

Hyang Cho Ja , Woon Jung Hae , Shik Shim Kye

Purpose: Both timing of menarche and growth patterns have changed with time. Menarche is supposed to important role in pediatric linear growth. This study is aimed to investigate the relationship between the timing of menarche and pubertal growth, specifically to analyze when menarche occurs related to the pubertal growth spurt, and how the pubertal height gain is related to the timing of menarche.Method: From January 20...

Objective Summarizing and analysing the clinical characteristics of 193 patients with McCune-Albright syndrome (MAS) in China to improve the understanding of MAS for early detection, diagnosis and management. Methods All MAS-themed case-report or case-series studies published by the Chinese between January 1990 and November 2022 were retrieved from the Wanfang Full Text, CNKI, China Science and Technology Journal, PubMed and Embase databases, and clinical data were collected. ...

Evaluation of new cutt-off points of the LHRH stimulation test in the diagnosis of central precocious puberty

Valls Llussà Aina , Murillo Vallés Marta , Martinez Couselo Silvia , Sol Ventura Paula

Introduction: Central precocious puberty (PPC) is defined by the appearance of sexual characters at a chronological age lower than -2.5DS of the average for the reference population. Diagnostic is clinical but the hormonal assessment is essential. Basal gonadotropin values are not enough for the diagnosis. Gonadotropin-releasing hormone (GnRH) stimulation tests evidence the activation of the hypothalamic-pituitary-gonadal axis, however there is controversy abo...

Remission in pediatric hyperthyroidism treated with methimazole

Ricci Jaime , Castro Bethania , Sabino Franco , Fasano Victoria , Tournier Andrea , Balbi Viviana , González Verónica , Morin Analía

Introduction: Hyperthyroidism (HT) is a condition characterized by inappropriately high thyroid hormone (TH) activity at receptor level, due to high synthesis and secretion of TH by thyroid gland. Antithyroid drugs as methimazole (MMI) are used as the first-line therapy in children. However, the optimal treatment duration and the predictive remission factors are still controversial.Objective: To investigate outcome of MM...

Mandatory lockdown during COVID 19 pandemic obstaculized access to medical attention. Newborn screening (NBS) for congenital hypothyroidism (CH) in Buenos Aires province has been obligatory since 1995 and performed sustainedly. CH causes mental delay if not diagnosed and treated early.Objectives: The aim of this study was to determine if mandatory lockdown changed time of established NBS diagnosis steps.Mat...

Background: Hypergonadotropic hypogonadism (HH) is an hallmark of Turner Syndrome (TS) and hormone replacement therapy (HRT) is often required for pubertal induction; this retrospective study highlights the pituitary-gonadal axis during infancy (<5 years), childhood (5–10.9 years) and adolescence (> 11 years) in a cohort of TS patients enrolled between February 1999 to March 2023. Our aim is to underline the diagnostic role of Gonadotropins as a ma...

AMH levels in infancy and mid-childhood predict ovarian activity in adolescence: a longitudinal study of healthy girls

Bistrup Fischer Margit , Hagen Casper P. , Wohlfahrt-Veje Christine , Assens Maria , Busch Alexander S. , Tønnes Petersen Anette , Juul Anders , Main Katharina M.

Background: Anti-Müllerian hormone (AMH) is produced by granulosa cells in small follicles prior to gonadotropin dependent growth and serum levels reflect the number of small antral follicles. There are currently no longitudinal data of individual AMH levels from infancy to adolescence.Aim: To evaluate whether AMH in infancy and childhood is associated with AMH levels and ovarian morphology peripubertal and in adole...
