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 ...

Introduction: Graves’ disease (GD), the main cause of hyperthyroidism in children, is caused by thyrotropin receptor stimulating autoantibodies (TRABs) that activate thyroid hormone synthesis, secretion and thyroid growth. Therapeutic options are anti-thyroid drugs (ATD), 131-I or thyroidectomy. This study reports the experience of a Tertiary Pediatric Endocrinology Unit.Methods: Review of GD patients diagnosed from January/2001 to October/2017. Res...

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: Hyperinsulinaemic hypoglycaemia (HH) is one of the common causes of hypoglycaemia in infants and children. It can cause severe brain injury in children if not treated promptly. Diazoxide is first-line treatment for HH. Glucagon infusion is used in the management of children with HH. However it is unclear what dose of glucagon should be used in children.Objective and hypotheses: To evaluate the efficacy, safety and pharmacokinetics of intraven...

Background: Diabetic ketoacidosis (DKA) is the most serious acute complication of type 1 Diabetes mellitus (T1DM). It is important to know the factors associated with the development of DKA and elaborate preventive strategies to reduce their prevalence.Objective and hypotheses: To identify DKA predictive risk factors in the initial presentation of T1DM in children and adolescents.Method: We conducted a retrospective study, by analy...

Background: 46XY DSD with female phenotype is classified as complete gonadal dysgenesis (46XY CGD) if a uterus is present or a disorder of androgen synthesis or action if a uterus is absent. The genetic causes of 46XY CGD are not fully clarified. Less than 15% of the cases were found to carry mutations of the sex determining region Y gene (SRY).Purpose: The description of the rare case of two sisters affected of 46XY CPD and gonadoblastoma with SRY mutat...

Background: Atherosclerosis begins in childhood and progresses silently. Triglycerides/HDL ratio(TG/HDL) is a risk factor for cardiovascular diseases.Objective and hypotheses: To investigate TG/HDL as possible predictive factor for metabolic disorders in children.Method: Descriptive correlation, with 110 children (6–12 years old) in Sparta, Greece. Anthropometric and biochemical analyzes were performed.R...

Background: Hyperinsulinaemic hypoglycaemia (HH) is a common cause of hypoglycaemia in children. Glucagon is an important counter-regulatory hormone and the role of somatostatin is not known in children with HH.Objective and hypotheses: To understand the roles of glucagon and somatostatin in children with HH.Method: Children admitted for management of HH in our hospital were included in the study. Plasma insulin, glucagon and somat...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare syndrome characterized by unresponsiveness or resistance to the action of aldosterone. It manifests with persistent salt loss, resulting in hyponatremia, hyperkalemia and metabolic acidosis. High levels of aldosterone and renin activity, confirms the diagnosis. When the inheritance pattern is autosomal recessive it expresses as a severe systemic disease. Often occurs in the neonatal period and presents with recurrent ...

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....
