Background: In infants under 3 years of age acquired primary hypothyroidism caused by autoimmune thyroiditis is very rare. Hypothyroidism can manifest with different signs and symptoms and has a wide range of presentations from subclinical hypothyroidism to overt form.Objective and hypotheses: We describe a child with an unusual hypothyroidism presentation characterized by multi-organ involvement and related to acquired autoimmune thyroiditis during a ve...

Objective: Postprandial hyperinsulinaemic hypoglycaemia (PPHH) or “late dumping syndrome” is a well-recognised complication following gastrointestinal surgery and has been less commonly identified idiopathically in paediatric patients. This study describes and compares the characteristics, diagnosis, management and outcomes of paediatric idiopathic and surgical PPHH.Design: Retrospective chart review of child...

Background: Phthalates are ubiquitous environmental contaminants and endocrine-disrupting chemicals (EDCs). Nowadays, they are considered reproductive toxicants and in-utero exposure is well documented, although evidence of early life exposure is scarce, and needs to be described. Aim of this study is to assess phthalate exposure and its changes over the first months of life in a cohort of healthy full term infants and their mothers from a restricted area of t...

Background: The decreased immune tolerance caused by mutations of the autoimmune regulatory gene (AIRE) lead to a spectrum of variable organ specific autoimmune disorders known as autoimmune polyglandular syndrome type 1 (APS-1). The rarity of the syndrome and the heterogenous clinical manifestations at the onset of the disease may delay the diagnosis. Only when two major components of the triad chronic mucocutaneous candidiasis – hypoparathyroidism &nda...

Introduction: Ectopic posterior pituitary (EPP) is a radiological diagnosis likely caused by a migration defect that occurs during pituitary development. We aim to describe the clinical characteristics and hormonal deficiencies seen in patients with EPP.Method: Longitudinal observational study performed in a single [HK1] [NM2] centre from 1993-2020. As per MRI findings, cases were divided into three cohorts 1) C1: EPP on...

Background: The activation of the hypothalamus-pituitary-gonadal (HPG) axis during the first months both in males(M) and females(F) is named as minipuberty. Urinary gonadotropins (uGn) represent an unexpensive and non-invasive method of assessing pubertal development and they have recently been used also for studying minipuberty.Aims of the study are: 1) to describe the urinary hormonal pattern (uLH, uFSH, testosterone – uT, oestra...

Background: The COVID-19 pandemic continues to impact healthcare overall particularly in relation to diabetes. Initial studies showed delays in emergent healthcare utilization, decreased preventative care visits, and more severe presentations of new onset diabetes. However, the pathophysiologic relationship between COVID-19 and type 1 diabetes is not yet well understood.Objectives: Our primary objective was to compare th...

Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder, occurring in 1/13,700 births. BWS is usually sporadic, but 15% of cases are familial. Variable phenotype may include overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, lateralized overgrowth and predisposition to embryonal tumors. We describe three male cases of BWS followed at our clinic.Case 1: Born of a gestation complicated by gestational diabetes. Del...

Background: The GH/IGF-I axis is involved in metabolic control and studies suggest that IGF-I deficiency and subsequent changes in IGF-I signaling in brown adipose tissue (BAT) modifies its thermogenic capacity. Food restriction reduces thermogenic capacity in BAT, while leptin stimulates thermogenesis through uncoupling protein 1 (UCP-1) induction. Leptin and IGF-I maintain important crosstalk in different tissues, but whether these two hormones interact to r...

Background: in general population Hurthle cell cancer (HCC) accounts for 3-7% of all differentiated thyroid cancers (TC) with a more aggressive course, while its relative prevalence and behavior in childhood is uncertain due to the lack of specific literature reviews.Objective: to describe the largest pediatric HCC cohort to date reported and to estimate its relative prevalence among TC variants in childhood.<p c...
