Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. To date more than 10 genes are associated with HR, and a comprehensive molecular diagnosis in these disorders is technically difficult to perform.Objective and hypotheses: To assess the value of targeted next-generation sequencing (NGS) used for molecular analysis of candidate genes of HR.Method: 64 pa...

Objectives: Assess thyroid volume in relation to TSH and FT4 at diagnosis of AHT and 2.9 years of follow up in children with SH or OH.Methods: wo hundred one children (155 girls) with AHT were divided according to TSH and FT4 levels [SH-FT4 >1.0 ng/dl: Group 1: TSH: 5-7.5 mU/l, Group 2: TSH: >7.5 mU/l, OH: Group 3: TSH>7.5 mU/l and FT4 ≤1.0ng/dl]. Mean L-T4 dose is reported in µg/Kg/day. Thyroid...

Background: To date, six cases of 17p13.1 microduplications have been described in the literature. Intellectual disability is the core feature, together with minor facial dysmorphisms and obesity later in life, but a characteristic phenotype for 17p13.1 microduplication has not been delineated.Objective and hypothesis: We describe a young patient with a 422 Kb microduplication maternally inherited in 17p13.1, affected by mild intellectual disability and ...

Objectives: Assess the dose of levothyroxine in relation to TSH and FT4 levels at diagnosis of AHT in children with SH and OH.Methods: Eighty eight children (69 girls) with AHT were devised in regard with TSH and FT4 at diagnosis [SH-FT4 >0.9 ng/dl: Group 1: TSH: 4.5-7 mU/l, Group 2: TSH: 7-10 mU/l, Group 3: TSH: >10 mU/l and OH: Group 4: TSH>10 mU/l and FT4 ≤0.9 ng/dl]. Mean L-T4 dose was reported in μgr/Kg per day at diagnosis an...

Background: Non Hodgkin lymphoma (NHL) is the fourth most common malignancy in childhood. Chemotherapy constitutes the first line treatment and may cause several endocrine side effects (growth retardation, hypergonadotrophic hypogonadism, bone mass loss and rarely secondary malignancy). In total of 1–2% of children may harbour thyroid nodules. The most common risk factors are: irradiation, female sex, iodine deficiency, puberty and past medical history of thyroid disease....

Background: The association of primary hypothyroidism and isosexual precocious pseudopuberty in females was first described in 1960 by Van Wyk and Grumbach. The unique elements that lead to the diagnosis are FSH-dominated sexual precocity with non advanced bone age in the presence of hypothyroidism.Objective and methods: Describe an 8.5 years old girl with hypothyroidism due to HT and clinical and hormonal features of Van-Wyk and Grumbach syndrome.<p...

Background: Children’s and parents’ expectations regarding GH therapy results have been previously assessed. However, there are limited data on children’s and adolescents perceptions of their own body size as compared with that of their age-related peers, as well as their expectations of their final stature.Objective and hypotheses: To evaluate the perceptions of GH treated children and their families for the child’s stature and to as...

Background: Treatment compliance is one of the most important practical aspects in long-term treatments such as GH therapy.Objective and hypotheses: To evaluate the level of compliance and its association with duration of treatment and other demographic factors.Method: A prospective study with the use of validated questionnaires was conducted in the Endocrinology Department of one of the two main Pediatric Hospitals in Athens. The ...

Objective: Compare HOMA-IR between obese and normal weight children.Methods: 292 children (156 females), BMI (≥0SD), Tanner stage 1/>2: 163/129, divided in four groups (Group 1: 0SD<BMI<2SD, Group 2: 2SD≤BMI<2.25SD, Group 3: 2.25SD≤BMI<2.5SD, Group 4: BMI≥2.5SD) were analyzed retrospectively from the medical records. Age, sex, fasting blood glucose and insulin as well as the ho...

Objective: Compare triglycerides, total cholesterol, HDL and LDL levels between obese and normal weight children.Methods: 547 children (286 females) with BMI (≥0SD) were divided in four groups (Group 1: 0SD<BMI<2SD, Group 2: 2SD≤BMI<2.25SD, Group 3: 2.25SD≤BMI<2.5SD, Group 4: BMI≥2.5SD) and analyzed retrospectively from the medical records. Age, sex, BMI z-score, triglycerides, tot...
