Background: Clinical observations of children and adolescents with differentiated thyroid cancer (DTC) patients led us to investigate quality of life and anxiety. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.Objective and Hypotheses: In this cross-sectional pilot study, our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquire...

Mineralization defects and paradoxical mineralizing enthesopathies are hallmarks of X-linked Hypophosphatemia (XLH), a rare skeletal disease caused by inactivating mutations in the PHEX gene (Phosphate-regulating endopeptidase homolog, X-linked). The current medical treatment, which consist in oral phosphorus supplementation and active vitamin D analogues, aimed at counteracting consequences of FGF23 excess and is commonly prescribed from early childhood to the end of...

Introduction: During the COVID-19 pandemic, we have seen an increase in consultations for Precocious puberty (PP) and accelerated puberty.Aim: To assess the frequency of PP and its progression before and during the pandemic.Materials and Methods: We retrospectively evaluated the patients's medical records referred to a Paediatric Endocrinolgy Unit between April 2018-March 2021...

Background: The two most commonly known types of Diabetes Mellitus (DM) are DM type 1 and DM type 2, characterized by insulin deficiency and insulin insensitivity, respectively. DM can also be associated with rare mutlisystemic syndromes such as Alstrom, Bardet-Biedl, Wolfram and pigmentary hypertrichosis insulin dependent diabetes (PHID) syndromes.Objectives: To understand the genetic and molecular basis of syndromic DM in a large cohort of patients.</p...

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

Background: Despite advances in genetic diagnosis and surgical technique, and guidance from the Consensus Statement on Intersex Disorders, aspects of clinical management in disorders/differences of sex development (DSD) remain unsettled. Actively debated decision points include gender of rearing in specific syndromes, genital surgery prior to the patient developing the capacity to provide assent, and uncertainty over how and when to best educate young patients about diagnostic...

Background: Reports suggest that youths with short stature (SS) exhibit academic under-achievement relative to cognitive aptitude and GH treatment diminishes the difference. However, interpretation of this achievement-aptitude discrepancy is confounded by the use of achievement and intelligence tests normed in different samples.Objective and hypotheses: To assess whether reports of academic underachievement in SS samples are partially attributable to cho...

Objective: Low birth weight and prematurity are linked to various behavioural outcomes. In addition, preterm (PT) infants show altered maturation of pituitary–gonadal axis, as demonstrated by its pronounced transient activation during the first postnatal months. Given that gonadal steroid hormones shape the basic processes of neural and behavioural sexual differentiation these elevated sex steroids in premature infants might affect the developing brain and alter subsequen...

Background: Insulin-like growth factor I (IGF-I) is one of the important hormonal mediators of human growth. Circulating IGF-I exists in a ternary complex bound to the acid-labile subunit (ALS) and one of its six binding proteins (BPs). IGF-I bound to ALS and BPs needs to be liberated by either Pregnancy Associated Plasma Protease A (PAPP-A) or A2 (PAPP-A2) to reach its receptor. Stanniocalcin 2 (STC2) is a potent inhibitor of both PAPP-A and PAPP-A2. Genome-wide association s...

Abnormal phenotypes in patients with ring chromosome X can be ascribed to failed or partial X inactivation due to loss of XIST on Xq13. We describe a mother and 1 daughter with the same mosaic karyotype, and another daughter with 45, X. KZ, 12 years old and recently moved from Poland, was investigated for short stature (Ht SDS -2.1), her mother was 142.9 cm, father 176.1cm. Both were healthy and not dysmorphic. Birth weight at 37 weeks was 2.63kg (20th centile Polis...
