Background: Early-onset severe obesity due to leptin deficiency typically results from a defect of leptin production or secretion due to mutations in the leptin gene. Recently we described a new form of leptin deficiency caused by bioinactivity of the hormone and associated with high circulating leptin levels (New England Journal of Medicine 2015 372 48–54).Method: Serum leptin was measured by ELISA. The leptin gene was seq...

Background: MicroRNAs (miRNA) are small non coding RNA molecules, key regulators of metabolic pathways. Obesity is characterised by many metabolic changes. NAFLD is seen as a complication of obesity. FOXO-1, key regulator in insulin signalling, has been shown to be implicated in NAFLD. We previously identified miRNAs regulators of the FOXO-1 gene.Objective and hypotheses: To assess in serum whether the regulation of miR-146a and miR-486-5p, FOXO1 gene re...

Papillary cancer represents majority of thyroid malignancies in children. However prognosis remains very successful. In recent years, we use elastography, except biopsy and standard ultrasonography in thyroid lesions diagnostic. We present a case of a male patient at the age of 13 years, with a history of ADHD and school phobia who was referred to Endocrinology Outpatient Clinic due to partial empty sella syndrome. Family history of endocrinological disorders was negative. Ph...

BMP4, a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily, is involved in the embryonic development of various organ and tissues including the cranio-facial structures, olfactory placode, pituitary, eyes, heart, and kidneys. Mutations in this gene are associated with orofacial cleft and microphthalmia in human patients. BMP4 plays an important role in the embryonic development of the GnRH neurons ...

Background: Short stature homeobox-containing gene (SHOX) is located within the pseudoautosomal region 1 (PAR1) of the sex chromosomes. SHOX mutations and PAR1 deletions encompassing SHOX or its upstream/downstream enhancers have been identified in ~60% of Léri-Weill dyschondrosteosis (LWD) and ~5–15% of idiopathic short stature (ISS) patients. Recently SHOX duplications have been described in LWD/ISS individuals.Case presentation: The boy was ...

Background: The prevalence of macrovascular complications is probably underestimated in children with type 1 diabetes (T1D). Arterial stiffness (AS) represents a subclinical marker of CV risk. The most validated non-invasive method for AS measurement is pulse wave velocity (PWV). There are limited numbers of studies with PWV on children with T1D.Aim: Our aim was to assess the relationship between AS and parameters associated with metabolic control in chi...

Introduction: XLH is caused by mutations in PHEX leading to increased FGF23 levels, phosphate wasting, and impaired endogenous calcitriol synthesis. Affected patients present with rickets and diminished growth velocity during childhood, and osteomalacia and short stature in adulthood. Adult height is linked with health within and across generations suggesting that adult height may be a potential tool for monitoring health conditions, e.g., XLH.<p ...

Background: At present few data have clearly showed an increased frequency of idiopathic central precocious puberty (CPP) in females during the COVID-19 pandemic. The role of environmental factors is not fully understood and various hypotheses have been formulated.Aims of the study: To evaluate retrospectively the incidence of newly diagnosed CPP and other pubertal disorders (Premature thelarche, early puberty, fast pube...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...

Background: Ovotesticular Disorder of Sex Development (OTDSD – true hermaphroditism) is rare, characterized by the presence of both presence of both testis and ovay tissue. Usually, these patients seek medical attention due to ambiguous genitalia.Case presentation: A 15-year-old boy, with ‘atypical’ genitalia and breast enlargement came for surgical correction. His genitalia had a more masculine aspect at birth and he had been submitted to...
