Background: Small for gestational age (SGA) without subsequent catch up growth is an indication for GH treatment in Europe, the US, and Korea but not in Australia. However, many SGA are likely to be included under the ‘short stature and slow growth’ (SSSG) indication. It is unknown to what extent children born SGA are included in the Australian indications or how they differ from non-SGA patients within each indication and gender.Objective and ...

Background/hypothesis: Congenital hyperinsulinism in infancy (CHI) mainly arises from mutations in ATP-sensitive potassium channel genes. However, the expression pattern of defects can be markedly diverse. In diffuse CHI (CHI-D) all islet cells express gene defects, whereas patients with focal CHI (CHI-F) only express defects in a localised region of islet cells due to loss of a maternally-imprinted locus. Here, we examined the properties of a novel population of CHI islet cel...

Introduction: Nutrition, bodily activity, and behavior-modifying practices are recognized interventions in managing obesity. Our aim was to review available information on the short-term effects of intervention (3-4 months) on body composition of overweight and obese children and adolescents.Methods: We reviewed the anthropometric data (Weight, height (HtSD), and BMI of 16 obese children aged 12 +/- 2.2 years. Body compo...

Introduction: CHARGE syndrome is a rare constellation of congenital malformations caused by mutations in CHD7 gene. The acronym stands for coloboma, heart defect, choanal atresia, retarded growth and development, genital hypoplasia, ear abnormalities, and/or hearing loss. Endocrine disorders associated with this syndrome include hypogonadotropic hypogonadism, ...

Background: Pseudohypoparathyroidism type 1A (PHP1A) and PseudoPHP are caused respectively by maternal and paternal mutations involving those GNAS exons that encode the alpha-subunit of the stimulatory G protein (Gsα). Common to different forms of PHP1B is a loss-of-methylation (LOM) at one or several maternal GNAS exons, which likely reduces Gsα expression in certain tissues. In most autosomal dominant PHP1B variants (AD-PHP1B), LOM is restricted t...

Background: Apparent mineralocorticoids excess syndrome (AME) is an unusual cause of hypertension, caused by genetic mutation of type 2 11β-hidroxysteroid desydrogenase (11BHSD2) enzime, which metabolizes cortisol(F) to cortisone(E). Patients with AME born from consanguineous parents, are small for gestagional age (SGA) and could have nephrocalcinosis, hypokalemia and high plasma cortisol/cortisone relation (F/E).Objective: To tell the clinical and ...

Background: Rare congenital conditions with incongruence of chromosomal, gonadal, and phenotypic sex have been summarized as disorders of sex development (DSD). Included in DSD are conditions with diverse genetic etiology, varying levels of prenatal androgen effects, phenotypes, and subsequently, different medical treatments. Quality of life (QoL) and psychological wellbeing are indicators of successful psychosocial adaptation to the conditions. Studies addressing these issues...

Introduction: The diagnosis of a disorder/difference of sexual development (dsd) is an exceptional psychosocial situation. As the diagnosis is often made in childhood, the parents are the primary communication partners. In some cases, the impossibility of immediate sex determination of the child can be a traumatic experience with a negative impact on the relationship between the parents and the child, the couple and members of the entire family. It has been recommended by the ...

Background: The prevalence of obesity has increased dramatically in Greece in the last decades, and more than 30% of children and adolescents are currently overweight or obese. Obesity is associated with decreased circulating 25-hydroxyvitamin D concentrations, which might predispose to metabolic syndrome and cardiovascular morbidity and mortality.Objective and hypotheses: To determine serum 25-hydroxyvitamin D concentrations and their relationship to ca...

Objectives: Heterozygous mutations in the aggrecan gene (ACAN) are associated with idiopathic short stature, with or without advanced bone age (BA), osteochondritis dissecans (OCD) and early onset of severe osteoarthritis (OA). Variable features also include midface hypoplasia, brachydactyly, short thumbs and intervertebral disc degenerative disease.Methods: We reviewed 173 radiographs in 22 individuals (8F:14M), (three shoulders, 10 hands, 10 w...
