Background: Thyroid nodules (TN) are rare in children but often show more aggressive features than in adults. Irradiated childhood cancer survivors (CCS) are at risk for malignant thyroid nodules.Objective and hypotheses: To retrospectively compare the incidence of differentiated thyroid cancer (DTC), the clinical onset and the medium-term follow-up in a pediatric population (EC <18 years), with and without risk factors examined for TN, among 1990 an...

Background: Calculation of a urinary steroid metabolite ratio (uSMR) may be a useful method of improving diagnostic yield when investigating disorders of steroid hormone synthesis. Our aim was to investigate the range of uSMR in children with suspected disorders of steroid hormone synthesis.Methods: Ten ratios were calculated on steroid metabolite data analysed by GC-MS in urine samples collected between 2008 and 2010 from 94 children who were undergoing...

Background: The use of antipsychotic medication in medical practice is increasing in Europe. Antipsychotics have serious adverse effects like weight gain.Objective: Aim was to explore metabolic risk factors and glycaemic control in youths with type 1 diabetes treated with typical or atypical antipsychotics.Design and methods: Data of children, adolescents, and young adults with type 1 diabetes up to the age of 25 years and with dia...

Background: Macroprolactinomas in children below 10 years of age are rare. Usually prolactinomas respond well to dopamine agonists so that neurosurgical resection is rarely necessary. For non-responders to dopamine agonist therapy other extended treatment options have to be considered.Clinical case: We report a 14-year-old boy who presented at the age of 11 years with headaches for 5 years and progressive bilateral vision problems. The diagnosis of a mac...

Background: Kallmann syndrome (KS) is a rare clinical entity, characterized by the association of hipogonadotropic hypogonadism and hypo/anosmia, with an estimated prevalence of 1:8000 in males and 1:40 000 in females.Method: Retrospective study of cases of KS diagnosed in paediatric age. Genetic analysis was performed by PCR and DNA sequencing of KAL1, FGFR1, GNRHR, GNRH1, PROK2, PROKR2, KISS1R, TAC3, TACR3, and FGF8 genes.Results...

Background: The isodicentric Y (idic Y) is one of the most common aberrations of the Y chromosome. Most patients (pts) are chromosomal mosaics, including 45,X cell line.Objective and hypotheses: Our aim is to describe clinical and molecular features of our 45,X/46,Xidic(Y) cases.Method: We retrospectively evaluate the clinical description of nine cases (six females, one male, two with ambiguous genitalia) with mosaic karyotype 45,X...

Background: A good metabolic control in preschool children with type 1 diabetes (DM1) is particularly challenging, being easier and safer with continuous subcutaneous insulin infusion (CSII) compared with multiple daily injections (MDI).Objective and hypotheses: Evaluate and compare metabolic control of preschool children with DM1, before and 9 months after CSII therapy.Method: Analytical retrospective study of children under the a...

Background: Prader–willi syndrome (PWS) is characterized by decreased fetal activity, obesity, muscular hypotonia, MR, short stature, hypogonadism and small hands and feet. Little information is available concerning PWS and kidney involvement.Objective and hypotheses: We report two patients with PWS and congenital abnormalities of kidney and urinary tract (CAKUT).Method: First case: male, born at 35 weeks with caesarian sectio...

Background: Triple A syndrome is a rare autosomal recessive disorder characterized by adrenal failure, alacrima, achalasia, and a variety of neurological features. In 70% of the families it is caused by mutations in the AAAS gene. Linkage analyses indicated genetic heterogeneity and exome sequencing revealed two further genes causing triple A-like syndromes.Objective and hypotheses: To summarise the genotypes and phenotypes of classic triple A s...

Background: The association of NF1 with optic pathway glioma (OPT) and GH hypersecretion was initially described in some isolated cases, while the presence of PP was more frequently reported in these patients. Association of gigantism and precocious puberty (PP) in five children with OPT (isolated in two and associated with NF1 in three cases) has been recently published.Aims: To evaluate the frequency of GH hypersecretion in children with NF1 and OPT, t...
