Background: Gonadoblastoma is a rare tumour of the gonads presenting in childhood or adolescence. It is a lesion composed of a mixture of germ cells at different stages of maturation, with low malignant potential. It is associated with disorders of sex development (DSD), most commonly Turner mosaic syndrome with Y chromosome material (TMSY), and 46XY gonadal dysgenesis (GD). Little is known about the natural history and incidence of this rare tumour.Obje...

Background: Subcutaneous calcification is a rare clinical symptom in infancy. Progressive evolution and association with brachydactyly could be indicators of Albright hereditary osteodystrophy (AHO). In clinical practice, AHO is difficult to diagnose because of clinical heterogeneity. Typical features of AHO without any evidence of hormone resistance are termed pseudopseudohypoparathyroidism (PPHP; OMIM 612463).Case report: Male patient referred to study...

Background: Infantile obesity is nowadays a pandemic disease and needs a paediatrician interventional attitude. Since 1990 until 2010 it has trebled and the World Health Organization recommends prevention ‘as soon as possible’ even during the first year of life. A Spanish study (Aladino 2011) stimated the prevalence of overweight in boys as a 26.3% and in girls a 25.9% and the prevalence of obesity as a 22% and a 16.2% respectively. Our aim was to set up a new score ...

Background: Treatment with GH of children born SGA allows an increase in growth velocity (GV) and improves adult height. Increased insulin resistance has been described in these patients, which reverts after interrupting GH administration. However, long-term metabolic consequences are not clearly established.Objective and hypotheses: Describe insulin resistance (HOMA-IR index) and auxological development (GV and height) in SGA children treated with GH fo...

Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly, and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: Case report: a girl born at 36.5 weeks, BW 1.935 g (−3.2 SDS), length 41 cm (−4.4 SDS) and...

Background: Carney complex (CNC) is a rare multi endocrine neoplasia syndrome associated with endocrine and non-endocrine tumours. Three types of testicular tumour have been described; large cell calcifying Sertoli tumours (LCCST), Leydig cell tumours and testicular tumours of adrenal origin. LCCST is a rare benign stromal tumour, which has been observed in 41% of males affected with CNC, usually appearing in the first decade of life. It can be hormonally active, presenting wi...

Background: Hypercalcaemia secondary to malignancy is rare in children and adolescents. Parathyroid hormone related peptide (PTH-rP) secreted by malignant cells increases bone resorption and renal calcium retention causing hypercalcaemia. We report 2 cases of hypercalcaemia of malignancy refractory to treatment with pamidronate and corticosteroids but responsive to treatment with Denosumab and Zoledronic acid.Case 1: A 17-year-old boy with epidermolysis ...

Background: Chromosome analysis is always indicated in disorders of sex development (DSD), but the need for karyotyping in gender dysphoria (GD) is less clear.Aims and objectives: We therefore aimed to review the place of routine chromosome analysis in the management of GD in children and adolescents.Patients and methods: 490 children and adolescents with GD have been referred to the two endocrine clinics forming part of the joint ...

Background: A disease of the immune system, responsible for 95% of cases of hyperthyroidism in children is very rare at this age, it affects one child in 10 million.Presentation: Khadija 3 year old girl admitted for goiter, no goitrogenic substances No drug Shot, No Inbreeding, goiter paternal aunt, The trouble was in the beginning 1 year a height and weight advance:+1 DS weight, height+3.2 DS, weakness, weight loss, Profuse sweating, tachycardia, irrita...

Background: TV-1106 (Teva Pharmaceuticals) is a genetically fused human GH and human serum albumin, in development for treatment of GH deficiency (GHD). TV-1106 has an extended duration of action compared to daily GH treatment and thus it is believed that treatment with TV-1106 can reduce the frequency of injections and improve compliance and quality of life for those requiring growth hormone replacement therapy. The efficacy and safety data from adult studies with TV-1106 sup...
