Background: Disorders related to an impairment in parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that now encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and an in vitro assay of Gs&#9...

Background: CSII has some potential advantages and disadvantages for young children. For many young patients, it is easier and more convenient to take multiple daily doses of insulin with CSII than with a syringe or insulin pen.Objective and hypotheses: The growing popularity of type 1 diabetes (DM1) treatment based on continuous subcutaneous insulin infusion (CSII) raises a question of the group of patients that benefit most from the treatment.<p cl...

Background: Progestins such as lynestrenol (L) can be used in female to male (FtM) adolescents with gender dysphoria (GD) who have advanced pubertal development to reduce the psychological burden of menstruation. L can later be combined with cross-sex hormones (testosterone esters) (L+T). L is much cheaper and easier to administer than GnRHa. To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To repo...

Background: Male to female (MtF) gender dysphoric adolescents with advanced pubertal development can be treated with antiandrogenic progestins such as cyproterone acetate (CA). CA is much cheaper and easier to administer than GnRHa and can later be combined with cross-sex hormones (17β-estradiol) (CA+E). To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To report the effects of consecutive CA a...

Background: Difficulties in transition of adolescent Turner Syndrome (TS) patients to adult health care has been reported in many studies.Objective and hypotheses: We conducted a medical and psychological follow-up of adult patients with Turner Syndrome which had been treated at our tertiary pediatric endocrine centre.Method: We screened for expected comorbidities and provided a questionnaire asking for current medical care. Furthe...

Background: Neonatal Graves’ disease (NGD) occurs in 1–2% pregnancies with maternal Graves’ disease. Thyroid auto-antibodies can persist in the maternal circulation even 10 years after thyroidectomy and can lead to NGD in the absence of maternal thyrotoxicosis. Both maternal stimulating autoantibodies and maternal thyroxine can cross the placenta, and have been implicated in neonatal craniosynostosis.Objective and hypotheses: We report a c...

Introduction: Benign hereditary chorea (BHC) is a rare, autosomal dominant disorder, described as a non-progressive chorea of early onset. BHC can present as single neurologic disorder (13%), brain and thyroid disease (30%) or ‘brain–lung–thyroid syndrome’ with congenital hypothyroidism and neonatal respiratory distress syndrome (50%).Case Report: 18 months old infant was admitted to the Endocrinology Outpatient Clinic with motor dela...

Background: There is currently limited data published on the prevalence of diabetic eye disease in children and young people (CYP) with type 1 diabetes mellitus (T1DM), yet diabetic retinopathy remains one of the commonest causes of blindness in young adults.Objectives: To determine the risk and prevalence of diabetic retinopathy and to evaluate the risk factors associated with diabetic retinopathy in CYP with T1DM.Methods: All CYP...

Background: Perinatal factors seem to influence the onset of puberty. There is some evidence suggesting that being born small for gestational age (SGA) is associated with early puberty, whereas the effect of large size at birth on timing of puberty is not clear.Objective and hypotheses: To evaluate the timing of puberty in children born SGA and large for gestational age (LGA) compared to children born appropriate for gestational age (AGA).<p class="a...

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...
