DICER1, a gene located on chromosome 14q32.13, encodes a protein ribonuclease (RNase) IIIb that plays a central regulatory role in miRNA processing. DICER1 syndrome has an autosomal dominant inheritance and predisposes affected individuals to a wide variety of tumors, both benign and malignant. We describe the case of a 6-year-old girl, carrier of a DICER1 germline mutation, and affected by a differentiated thyroid carcinoma. At the age of 6 a first thyroid ultrasound revealed...

Background: Recent studies have found a widespread deficiency of vitamin D during pregnancy. Its significance is still not fully understood, although low Vit-D levels have been associated to increased risk for conditions such as preeclampsia, bacterial vaginosis, neonatal sepsis, and early respiratory infections in the child. Supplementation to the pregnant mother is still a matter of debate, therefore it is important to understand better the causes, risk factors, and possible...

Background: Cornelia de Lange (CdLS) syndrome (OMIM #122470) is a complex disease, characterized by distinctive facial features, failure to thrive, microcephaly, intrauterine growth retardation and anomalies in multiple organ systems. The complexity and severity of the endocrine commitment is variable. NIPBL, SMC1A, SMC3, RAD21 and HDAC8 genes, all involved in the cohesin pathway, have been identified to cause CdLS. There are few published studies on the endoc...

Background/Aims: Magnetic resonance imaging (MRI) is used to investigate the etiology of growth hormone deficiency (GHD). There is a close relationship between structural changes in the pituitary gland and clinical status.We aimed to investigate the relationship between MRI findings and clinical symptoms and treatment response in children with GHD.Methods: The study was conducted in nine Department...

Introduction: Studies about pubertal onset and the menarcheal age in girls with the antecedent of idiopathic premature adrenarche (IPA) are limited and with discordant results. For these reasons, we created a cohort of girls with the diagnosis of IPA. The objectives of our study were: a) to know the age of pubertal onset; b) to evaluate menarcheal age; c) to determine the growth rate in the first two years after the IPA diagnosis; d) to collect adult height da...

Background: Prenatal dexamethasone (DXM) treatment has been proposed to prevent genital virilization in girls with congenital adrenal hyperplasia (CAH), however its safety has been questioned for potential adverse effects on the foetus and the mother.Objective and hypotheses: To analyse clinical practice and prenatal treatment experience with DXM during pregnancy at risk of having her daughters with severe CAH.Method: An online sur...

Background: Adenosine deaminase (ADA) deficiency is a systemic metabolic disease that primarily affects the immune system and lymphocyte development, causing a severe combined immunodeficiency (ADA-SCID). However, the accumulation of toxic metabolites occurs in other organs and systems. Since most ADA-SCID patients undergo definitive treatment with Gene Therapy (GT) or allogeneic haematopoietic stem cell transplantation (HSCT), preceded by conditioning (either...

Context: Differences in sex development (DSD) represent a broad spectrum of conditions that can present at different ages to various healthcare professionals with different backgrounds.Design: This is a retrospective, observational cohort that includes all DSD subjects referred to a multi-professional DSD team over a period of 41 years (from 1980 to 2021).Participants: A total of 6...

Though up to fourteen different MODY subtypes have been so far described, there are no studies in the literature which have determined their actual frequency and prevalence in pediatric patients.Objectives: To identify the underlying molecular basis in a cohort of pediatric patients with a suspected clinical diagnosis of MODY by targeted NGS.Materials/Methods: Cohort of 60 patient fulfilling MODY c...
