The 1st lockdown from March to May 2020 probably led to an increase in the number of cases of idiopathic central precocious puberty in several European countries. Two Italian studies showed this, as well as a Spanish and a Turkish one. We performed a retrospective study with all the children who came to our department for a 1st appointment or a check-up for pubertal signs between 01/04/2017 and 31/03/2021. We checked the data of 765 files and kept only the children with a diag...

Papillary thyroid cancer (PTC) is the most common thyroid tumor in childhood and adolescence. Most of these patients are referred with locally advanced and/or distant disease at the moment of diagnosis. Whenever is possible, these patients should be offered a total thyroidectomy and radioiodine remnant ablation. However, this approach is not always possible to perform, becoming these tumors as unresectable. These critical cases could benefit from the neoadjuvant treatment with...

McCune-Albright syndrome (MAS) is a rare disorder caused by somatic mutations in GNAS gene leading to fibrous dysplasia (FD), cafe-au-lait spots and hyperfunctioning endocrinopathies. The common feature of MAS in girls is peripheral precocious puberty (PP) with the recurrent ovary cysts. Few cases of ovary tumors have been described to date.8,5 year-old girl with MAS is closely observed in our centre since the age 4,5, when the diagnosis was est...

Background: The aim of our study is to determine the relation of vitamin D levels (25(OH)VD) with body-mass index (BMI), age and month of extraction in pediatric patients.Materials and Methods: We present a retrospective review of medical records of patients under 18 years of age visited by the Children's Endocrinology Service (overweight and obesity) and ambulatory pediatrics (healthy and normal weight children) at ...

Germ cell tumors (GCTs) comprise a heterogeneous group of neoplasms. The WHO classification 2016 recognizes three types of testicular GCTs, including the GCNIS-related (Germ Cell Neoplasia In Situ) GCTs, being the malignant seminomas and nonseminomas. They originate from a totipotent embryonic germ cell. GCNIS, seminoma and embryonal carcinoma, are characterized by the pluripotency marker OCT3/4 (POU5F1). Seminomas (and GCNIS) are positive for SOX17 and embryonal carcinomas fo...

Background: Body weight has a close correlation with bone mass in humans and high fracture rates has been reported in both obese and underweighted individuals. It is not clear the role of bone marrow adiposity (BMA) and the IGF system in this process.Aim: The aim of this study was to analyze bone composition and BMA in obese and non-obese children/adolescents and correlate them with the expression of the IGF type-1 receptor (IGF1R) in peripheral lymphocy...

Background: Obesity is one of the most frequent chronic diseases in the world, however the true prevalence of obesity in the RF remains at the moment insufficiently studied.Aims: To study the age features of the prevalence obesity in boys in the Udmurt Republic - the region in European part of the Russian Federation with the children population of 335 000.Methods: 4795 boys aged 1–17 years were surveyed, among them 2368 (49.4%...

Background: Osteogenesis imperfecta (OI) is a hereditary connective tissue disorder due to mutations related to collagen type 1. OI presents itself with low bone mass, resulting in high bone fragility. Bone mass is relevant for determination of the severity of OI. Although bisphosphonate treatment is able to increase areal bone mineral density (aBMD) measured by DXA, there is no correlation to fracture rates.Objective and hypotheses: The aim of this stud...

Background: The syndrome of Taybi-Linder (TALS) or paramount dwarfism microcephalic of type 1 (MOPD1) is an uncommon illness characterized by an intra-uterine delay of growth, multiple malformations (short members, facial dysmorphie) and especially of the cerebral abnormalities. The infants carrying this disease can live until the age from 2 to 3 years and, often at the time of an infection, their state worsens quickly in a few hours (conscience disorder, convulsions) until th...

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...
