Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Introduction: The neuropeptide oxytocin (OT) plays an important role in modulating behaviour and social interactions. Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder due to abnormal hypothalamic development including OT dysfunction that involves endocrine, nutritional and behavioural outcomes/features/trajectory. We previously showed in a phase I/II study (NCT02205034) that 18 infants with PWS, less than 6 months of age, who received ...

Background/Aims: Pediatric obesity remains an ongoing serious international health concern. Whether liver dysfunction is related to thyroid dysfunction in this population is controversial. Compare SGPT, TSH, FT4 and insulin resistance indexes between children with obesity or severe obesity.Methods: 279 children (143 females) with ΒΜΙ (≥95percentile) (CDC BMI curves) were divided in two groups (Group 1, ob...

Background: DICER1 is an endoribonuclease that acts post-transcriptionally by processing mRNA into siRNA and microRNA, thus leading to mRNA downregulation. DICER1 syndrome is usually caused by germline variants and is characterized by a variety of benign or malignant tumors: pleuropulmonary blastoma, ovarian Sertoli-Leydig cell tumor, cystic nephroma, pituitary blastoma and multinodular goitre. Patients with germline aberrations in the DICER1 gene may carry additional...

Aim: To evaluate the relationship between smoking and metabolic parameters in patients affected by type 1 diabetes (T1D)Patients and methods: We enrolled 104 children and young adults (50 females and 54 males) with T1D (aged 16.4±8.6 years). The subjects were divided into three groups according to their smoking habits: no smoking (NS), passive smoking (PS), active smoking (AS). The physical examination of the participants included nutritional status...

Introduction: Pubertal growth is hormone dependent. The anthropometric (height, weight) and sexual (Tanner stage (TS)) changes are accompanied by growth in foot length. However, the relationship between changes in foot length and other anthropometry remains unclear. Our aim was to determine how changes in foot length relate to growth parameters (height and weight), self-rated TS and serum sex steroids.Methods: We used data from the Adolescent Rural Cohor...

Background: Paediatric pituitary adenomas are rare and mostly benign disorders which may secrete pituitary hormones. Prolactinomas account for half of all pituitary adenomas (PROLA), followed by non-secreting adenomas (20–40%; incidentalomas), adrenocorticotropic-hormone secreting adenomas (10–30%; ACTHA) and growth-hormone-secreting adenomas (5–15%; GHA).Methods: In this single-centre retrospective analysis clinical, biochemical and radio...

Background: The ability to respond to stress constitutes a defensive protective mechanism; both inadequate and excessive responses may be detrimental.Objective and hypotheses: To investigate the effect of increased body weight on the hormonal response to stress in children. Scheduled surgical procedures include two stressful parts, a psychological one (anticipation of operation) and a biological one (surgical stress per se) and were chosen as a study mod...

Background: Anorexia nervosa (AN), a state of chronic nutritional deprivation prevalent in children and young adolescents, is associated with major changes to the hypothalamic–pituitary axis including the GH–IGF1 axis, thyroid function, hypercortisolemia, and hypogonadotropic–hypogonadism, with delayed puberty and a low growth velocity (GV) at a time critical for the pubertal growth spurt, potentially affecting adult height. The effects of supraphysiological hum...

Background: Insipidus diabetes is a rare disease in pediatric endocrinology.Objective and hypotheses: Facing a thickened pituitary stalk on MRI pituitary, the main diagnosis to mention are: dysgerminoma, histiocytosis, sarcoidosis, and autoimmune hypophysitis. Histiocytosis is a rare and often underdiagnosed cause.Method: We report the case of a teenage girl who presented polyuria–polydipsia syndrome at the age of 14 years con...
