Background: Disorders of sex development (DSD) are congenital conditions in which chromosomal, and gonadal or anatomical sex is atypical.Objective and hypotheses: We describe the case of a 46,XX newborn with ambiguous genitalia. 46,XX DSD set in differential diagnosis disorders of gonadal development (ovotesticular DSD, testicular DSD, gonadal dysgenesis), androgen excess of fetal (mainly congenital adrenal hyperplasia due to deficiency of 21-hydroxylase...

Background: Infants born small (SGA) and large (LGA) for gestational age have been identified at increased risk of perinatal morbidity and later cardio-metabolic alterations. Nevertheless, the progression over time in incidence of SGA and LGA births is yet to be determined.Objective and hypotheses: To investigate temporal trends in SGA and LGA infants compared to those born appropriate (AGA), and to identify factors potentially associated over a 20-year ...

Background: ROHHADNET syndrome affects children with normal development until 2–4 years. A paraneoplastic/autoimmune etiology has been suggested because of the association with neural crest tumours.Objective and hypotheses: Aim of this study was to describe the phenotype of ROHHADNET patients, and to evaluate a possible role of autoimmunity in this disorder. In spite of a suspicion for genetic etiology, disease-associated genetic variations have not...

Objective and hypotheses: A retrospective review of bone morbidity in a contemporary cohort of boys with Duchenne muscular dystrophy (DMD) managed in a Scottish tertiary neuromuscular centre.Method: Clinical details and results of bone surveillance were obtained in 47 boys, aged 9 years (2–16). DXA bone mineral content (BMC) at total body (TB) and lumbar spine (LS) were adjusted for bone area. Fractures were classified based on radiological confirma...

Background: Obese adults with normal glucose tolerance (NGT) but 1-h post load glucose (1 hPG)≧155 mg/dl have an increased cardiometabolic risk. In children, preliminary data suggest that 1hPG≧132.5 mg/dl might identify those at higher risk of type 2 diabetes.Objective and hypotheses: To assess whether NGT obese youth with 1hPG ≧132.5 mg/dl (High-NGT) have worse insulin sensitivity and secretion compared to obese youth with 1hPG &#60...

Background: Vitamin D is now recognised as a prohormone, essential for the maintenance of mineral homeostasis, calcium metabolism and normal skeletal architecture. 30 ng/ml or greater can be considered sufficient serum levels. The prevalence of vitamin D deficiency among severely obese children is almost 49% caused by the fact that it is sequestered in the larger body pool of fat of such individuals, being vitamin D fat soluble. Vitamin D deficiency has been recently associate...

Background: Vaptans, vasopressin receptor 2 antagonist, are used in adults to treat hyponatremia associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). To date, in paediatric patients with SIADH there are few data about use of vaptans, still considered off-label.Case presentation 1: A 9-yo female with surgically treated suprasellar astrocitoma developed chronic hyponatremia (121–128 mmol/...

Background: Congenital primary hypothyreoidism occurs in about 1 of 3 600 life births and is usually detected with newborn screening. Early levothyroxine treatment is the prerequisite for normal psychomotor development of affected children. However, patients suffering from congenital central hypothyroidism are missed by the screening procedure, which may lead to delayed diagnosis and therapy. In very rare cases central hypothyroidism is caused by isolated TSH deficiency due to...

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Introduction: Female patients treated with alkylating agents in childhood are at risk for ovarian impairment. We aimed at describing the pattern of residual ovarian function in a cohort of hematological cancer survivors, assessing the relationship between the cumulative dose of alkylating agents administered (expressed as Cyclophosphamide Equivalent Dose - CED) and Anti-Müllerian Hormone (AMH) levels.Methods: Gonada...
