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...

Background: Forkhead box P3 (Foxp3) is an important regulatory factor for the development and function of T regulatory cells (Tregs). Moreover it has been established that deficiency of the Foxp3 gene in Treg cells suppresses their regulatory function leading to the development of autoimmune diseases especially autoimmune thyroid diseases (AITDs).Objective and hypotheses: The aim of our study was to estimate the association of three polymorphism of FOXP3...

Background: Insulinomas are very rare in childhood with sparse knowledge on the clinical aspects and the presence of Multiple Endocrine Neoplasia type 1 (MEN1).Methods: We conducted a multicentre retrospective review of patients diagnosed with insulinoma between 1995-2021. Clinical, biochemical, genetic, imaging and histological data were collected. In addition, follow-up and family data were obtained.<p class="abste...

Background: Congenital hypopituitarism (CH) genetics is highly heterogeneous. The massive use of NGS identified at least 21 desease causing genes. Not fully understood inheritance mechanism, incomplete penetrance and variable expressivity explain the complexity of phenotype-genotype correlations. To further complicate the scenario, the co-occurence of more than one desease-causing genes variants can geopardize the phenotype. Herein, we report the heterogeneous...

Background: It was reported recently that central adrenal insufficiency (CAI) in pediatric patients (pts) with Prader-Willi Syndrome (PWS), presented in up to 60% of them, could be a potential cause of sudden death. Moreover it has been suggested that CAI could be aggravated by rhGH recombinant human growth hormone (rhGH) treatment.Objective: To prevent both over- and undertreatment with hydrocortisone, we assessed the p...

Background: Congenital hypopituitarism (CH) is characterized by a deficiency of one or more pituitary hormones. Mutations in the genes coding for transcription factors, such HESX1, involved in the development of the pituitary, determine a highly variable phenotype which may include severe midline defects, septo-optic dysplasia and other congenital abnormalities. A small number of HESX1 variants have been identified in humans. The phenotype sh...

The diagnosis of central adrenal insufficiency (CAI) is challenging. The most popular diagnostic tool in pediatric population remains low-dose (1 μg) cosyntropin (LDC) test. Nevertheless, there is still a need for the CAI markers that might be used on an outpatient setting as a first-line screening. In adult patients morning cortisol and dehydroepiandrosterone sulphate (DHEAS) has been postulated as a possible markers. The aim of the study was to evaluate the usefulness of ...

Purpose: Anorexia nervosa (AN) increases the risk of impaired bone health, low areal bone mineral density (aBMD), and subsequent fractures. This study investigated the long-term effects on bone and biomarkers in young women with AN.Methods: Twenty-five Swedish female AN patients, median age 21.0 years (16.1 to 24.3 years), median BMI 15.4 kg/m2, were included, 22 patients completed a high-energy in-patient treatment for ...

XLH is the commonest inherited form of rickets. Impaired regulation of fibroblast growth factor 23 (FGF23) due to PHEX gene mutation leads to reduced tubular reabsorption of phosphate (TmP/GFR) and 1,25-dihydroxyvitamin D (1,25(OH)2D) synthesis with hypophosphatemia. Patients show rickets and osteomalacia, bone and muscular pain, stunted growth, and reduced quality of life. We report preliminary data on burosumab therapy in a selected sample of Italian patients.<p class="a...

Background: The COVID-19 pandemic has had wide effects on child health globally. Increased prevalence of childhood obesity has been observed during the pandemic. The absence of a formal societal lockdown during the pandemic, made Sweden stand out compared to other countries. Several studies have shown increases in obesity in children during the COVID-19 pandemic. These studies mainly focused on school age children and adolescents in countries that underwent pe...
