Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive genetic defects in cortisol synthesis caused by the deficiency of 21-hydroxylase which convert 17-hydroxyprogesterone to 11-deoxycortisol. A variety of mutations in one or more genes encoding enzymes essential for cortisol synthesis leads to a spectrum of disorders and disease severity. In general, complete or nearly complete enzymatic defects result in overt adrenal insufficien...

Background: Fibrous dysplasia (FD) is rare disease that affects skeletal system characterized mostly by abnormal bone formation. The newly formed disorganized mass includes fibrous tissue with poorly organized immature trabeculae. FD is a highly incapacitating condition where fractures, deformities and consecutive functional impairment could occur as mono, olygo or polyostotic form. Aside from predominantly asymmetric skeletal involvement, extra-skeletal manif...

Objective: Premature ovarian insufficiency (POI) is rare in adolescents, most commonly caused by genetic defects or cytotoxic therapy. The aim is to present the case of an adolescent girl with normal pubertal progress and irregular menstrual cycle, followed by amenorrhea.Case presentation: A 15 9/12-years-old girl presented because of lack of menses for the previous 21 months. She reported that she had menarche at the ag...

Background: It is critical to understand patient-reported outcomes in pediatric patients enrolled in pediatric weight management (PWM) clinics. Health-related quality of life (HRQoL) is low in children with obesity. Utilizing data from the CANadian Pediatric Weight Management Registry (CANPWR), we examined (1) changes in HRQoL up to 3 years after enrollment in PWM and (2) factors associated with change in HRQoL over time.Methods:...

Background: 46,XY gonadal dysgenesis (GD) is a spectrum disorder which lead to variable degrees of atypical external genitalia, ranging from female to micropenis and absent of gonadal tissue (known as Embryonic Testicular Regression Syndrome -ETRS). Most patients with 46,XY GD remains without a molecular diagnosis.Objective: To report the DEAH-box helicase 37 gene (DHX37) as a novel candidate for the GD etiology.Patients a...

Introduction: Maternal thyroid disease is considered as a risk factor for abnormal thyroid function at birth as well as for long-term morbidity in offspring. The potential harmful effects on the neonate had led to the clinical practice of thyroid function assessment in infants born to mothers with thyroid disease during pregnancy, despite well-established newborn screening programs with include congenital hypothyroidism screening. We evaluated the usefulness o...

Background: CFRD is a unique subtype of diabetes mellitus, distinct from type 1 and type 2, harbouring β-cell dysfunction and β-cell loss and insulin resistance. Modulator therapies directly target the underlying defect of CF, modulating or correcting the function of the CFTR gene (mutation-specific). Few studies investigated the effect of modulators on CFRD and glucose metabolism. We performed an observational study on the short-term effects of the ...

Background: The PAX8 gene (Paired box gene 8) is located on the long arm of chromosome 2 (2q12–q14), contains 12 exons and encodes a similarly named PAX8 protein. This protein is a transcription factor which in the thyroid gland is essential for the follicular cells formation and takes part in the expression of the thyroid-specific genes (TG, TPO, and SLC5A5). Variants in the gene have been previously associated with autosomal dominant thyroid dysgenesis...

Background: Obesity in adolescence represents a major health problem of our century owing to its epidemic proportions and the associated morbidity and mortality in adult life. In Greece, 41% of adolescents are overweight or obese.Aim: The aim of our study was to investigate the effectiveness of a comprehensive, multidisciplinary, personalized management plan at reducing the prevalence of overweight and obesity in adolesc...

Osteogenesis imperfecta (OI) is a rare, hereditary bone dysplasia with a broad clinical spectrum that includes skeletal and extra-skeletal manifestations. It is genetically heterogeneous and there are multiple described mutations that explain the clinical variability of this entity and make it difficult to establish a genotype-phenotype correlation.Objectives: To evaluate the clinical and genetic characteristics of the patient with OI.</...
