INTRODUCTION: The aim of this study was to evaluate (i) the knowledge about different dimensions of sexual identity in a group of family pediatricians and (ii) the efficacy of a training program to improve knowledge and reduce genderism and heteronormativity. METHODS: A pre-post-follow-up study was conducted with 96 Italian pediatricians (48 men and 48 women) who participated in a 6-h training program and divided into 2 sections. The first section was theoretical and focused on the conceptual foundations of sexual identity, the depathologizing approach to gender diversity, and the role of pediatricians as the first contacts of children's or adolescents' family...

INTRODUCTION: Although the majority of Growth Hormone insensitivity syndrome (GHIS) cases are classical, the spectrum of clinical phenotypes has expanded to include "atypical" GHIS subjects with milder phenotypes due to very rare heterozygous growth hormone receptor (GHR) mutations with dominant negative effects. CASE PRESENTATION: A 13-year-old pubertal boy presented with short stature (-1.7 SDS) and delayed bone age (11.5 years). His serum IGF-1 was low (16 ng/ml; reference range: 179-540)...

INTRODUCTION: Childhood cancer survivors (CCS) are at risk for radiotherapy (RT) late effects, including second malignancies. Optimal screening for differentiated thyroid cancer (DTC) in CCS post-RT remains controversial. We assessed the outcome of thyroid ultrasound (US) surveillance in CCS exposed to RT. METHODS: 306 CCS were surveilled with thyroid US between 2002-2021. Surveillance was dependent on age at the time of primary diagnosis, interval from receipt of RT, and individual provider...

INTRODUCTION: Congenital hypothyroidism (CH), the most common neonatal endocrine disorder world-wide, can be caused by variants in the thyroid peroxidase (TPO) gene. This study aimed to identify TPO variants in Chinese patients with CH, analyze their impact on TPO function, and establish relationships between TPO genotypes and clinical characteristics. METHODS: A total of 328 patients with CH were screened for TPO variants by performing whole exome sequencing. The function of the detected TPO variants was investigated via transfection assays in vitro...

Introduction Although there are some recommendations in the literature on the assessments that should be performed in children on recombinant human growth hormone (rhGH) therapy, the level of consensus on these measurements is not clear. The objective of the current study was to identify the minimum dataset (MDS) that could be measured in a routine clinical setting across the world, aiming to minimise burden on clinicians and improve quality of data collection. Methods This study was undertaken by the GH Scientific Study Group (SSG) in GloBE-Reg, a new project that has developed a common registry platform that can support long-term safety and effectiveness studies of drugs...

INTRODUCTION: Exogenous insulin antibody syndrome (EIAS) rarely occurs in type 1 diabetes and should be considered in those with blood glucose levels outside the target range requiring greater than 2 units/kg/day of insulin without obesity. We describe the novel treatment of this condition using mycophenolate mofetil monotherapy in a pediatric patient in the outpatient setting. CASE PRESENTATION: A 17-year-old Caucasian male with type 1 diabetes experienced an abrupt increase in insulin requirements from 1...

INTRODUCTION: The SALL4 gene encodes a transcription factor that is essential for early embryonic cellular differentiation of the epiblast and primitive endoderm. It is required for the development of neural tissue, kidney, heart, and limbs. Pathogenic SALL4 variants cause Duane-radial ray syndrome (Okihiro syndrome), acro-renal-ocular syndrome and Holt-Oram syndrome. We report a family with vertical transmission of a SALL4 pathogenic variant leading to radial hypoplasia and kidney dystopia in several generations with additional growth hormone deficiency (GHD) in the proband...

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) leads to impaired glucocorticoid and mineralocorticoid synthesis with excess production of androgens. Replication of the normal circadian cortisol secretion is challenging and supraphysiological doses of glucocorticoids are often required. Most patients experience transient episodes of hyper- and hypocortisolaemia during the day leading to adverse metabolic outcomes such as insulin resistance, visceral adiposity and cardiovascular morbidity, including hypertension...

INTRODUCTION: Diagnosis of central diabetes insipidus (CDI) remains challenging. Water deprivation testing and hypertonic saline infusion, as established diagnostic tests, are mentally and physically demanding for patients. Arginine-stimulated copeptin has been shown as a putative parameter for the differential diagnosis of CDI in adults. METHODS: In this single-centre retrospective study, we identified paediatric patients with suspected pituitary disorders who underwent standard arginine-testing...

INTRODUCTION: Patients with homozygous recessive mutations in STAT5B have severe progressive postnatal growth failure and insulin-like growth factor-I (IGF-I) deficiency associated with immunodeficiency and increased risk of autoimmune and pulmonary conditions. This report describes the efficacy and safety of recombinant human IGF-1 (rhIGF-1) in treating severe growth failure due to STAT5B deficiency. CASE PRESENTATION: Three siblings (P1, 4.4 year-old female; P2, 2...

INTRODUCTION: The prevalence of polycystic ovarian syndrome (PCOS) in adolescent girls is between 1 and 4.3%. It remains controversial whether women with a history of idiopathic central precocious puberty (ICPP) are at increased risk for PCOS. Our objective was to assess the prevalence of PCOS in adolescents with a history of ICPP compared with healthy adolescents and the prevalence of PCOS among ICPP girls who have received or not gonadotropin-releasing hormone analogue (GnRHa) treatment...

INTRODUCTION: There are increased calls to address psychosocial needs among individuals with classical congenital adrenal hyperplasia (CAH). However, cross-cultural disparities exist in treatment practices and psychosocial outcomes that impact the generalizability of evidence-based recommendations. To date, this disparity has not been quantified. The present scoping review uses a dual approach to contrast rates of CAH diagnosis with CAH psychosocial research rates across countries. METHODS: Six electronic database searches were conducted for: (1) CAH incidence/birth/prevalence rates; and (2) psychosocial research with affected individuals and their families...

INTRODUCTION: Pathogenic biallelic RNPC3 variants cause congenital hypopituitarism (CH) with congenital cataracts, neuropathy, developmental delay/intellectual disability, primary ovarian insufficiency, and pituitary hypoplasia. Here, we aimed to evaluate the clinical and molecular characteristics of two patients with CH and neuropathy. MATERIAL AND METHODS: Proband was evaluated by clinical, laboratory, and radiological exams followed by exome sequencing (ES). Clinical investigation of an affected sibling and variant segregation in the family was performed by Sanger sequencing...

INTRODUCTION: Hyperinsulinemic hypoglycemia is the most common cause of persistent hypoglycemia in children and adults. In adolescents and adults, hyperinsulinemic hypoglycemia is most frequently caused by an insulin-producing tumor. CASE PRESENTATION: A 17-year-old, previously healthy male presented with recurrent and severe episodes of hypoglycemia. Diagnostic evaluation was consistent with hyperinsulinemic hypoglycemia, and an insulinoma was suspected. Multiple imaging studies and surgical exploration failed to identify a lesion...

Hyperinsulinism (HI) due to dysregulation of pancreatic beta-cell insulin secretion is the most common and most severe cause of persistent hypoglycemia in infants and children. In the 65 years since HI in children was first described, there has been a dramatic advancement in the diagnostic tools available, including new genetic techniques and novel radiologic imaging for focal HI, however; there have been almost no new therapeutic modalities since the development of diazoxide. Recent advances in neonatal research and genetics have improved our understanding of the pathophysiology of both transient and persistent forms of neonatal hyperinsulinism...
