Background: Melanocortin 4 receptor (MC4R) deficiency is the commonest monogenic form of non-syndromic obesity. MC4R is a seven transmembrane G-protein coupled receptor implicated in central regulation of body weight. The loss-of-function mutations in MC4R gene will contribute to early-onset obesity associated with hyperinsulinemia, hyperphagia and “binge eating”. We aim to determine the prevalence of MC4R variants in a Pediatrics...

Introduction: Individuals with ovotesticular disorders of sexual development (OT-DSD) have both seminiferous tubules and ovarian follicles. The combination of gonads could be separated (ovary-testis), unilateral (ovotestis-ovary or ovotestis-testis), or bilateral (ovotestis-ovotestis). The last one is the rarest variant (24.5%). In 60% of cases, the karyotype is 46, XX.Case Report: 15-year-old, monochorionic-monoamniotic...

Introduction: Nelson’s syndrome is a potentially severe complication of bilateral adrenalectomy, a radical procedure performed in the treatment of hypercortisolism in Cushing’s disease (CD). We report a case of CD in pediatric age submitted to bilateral adrenalectomy with subsequent Nelson’s syndrome.Case report: Male, 5-year-old, referred to a Pediatric outpatient clinic because of growth failure, rapid weight gain and high blood pressure...

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: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Introduction: Treatment with recombinant growth hormone (rGH) is safe and has greatly improved the approach of children and adolescents with growth hormone deficiency (GHD) and other growth disorders. Some studies show that most of the height gain associated with GH treatment occurs in prepubertal years. The aim of our study was to evaluate the effect of age at start of the treatment on final height in children with isolated or GHD in a Portuguese cohort.<p class="abstext"...

Background: Isolated growth hormone deficiency is the most common pituitary hormone deficiency, although the majority of cases are idiopathic. The presence of pituitary structural abnormalities may influence growth hormone (GH) deficiency severeness.Objective: Assess the effect of pituitary abnormalities in idiopathic isolated growth hormone deficiency (IIGHD).Methods: We analysed 65 children with IIGHD and pituitary magnetic resso...

Background: Besides surgery, radioactive iodine therapy (RAI) is an effective and safe option to treat children with hyperthyroidism from Graves disease (GD) who cannot achieve euthyroidism with antithyroid drugs.Objective and hypotheses: To present the experience of a Portuguese paediatric unit with the use of RAI in children with GD.Method: The authors performed a review of 7 cases of Graves disease of age under 18 years treated ...

Background: Type 1 diabetes mellitus (1DM) is a common chronic disease of childhood. Treatment targets the best metabolic control in order to prevent long-term complications.Objective: To evaluate metabolic control in children and adolescents with 1DM along the years. Methods: Retrospective study including 1DM children and adolescents with more than 2 years of disease. Data were collected at 2005 and at 2012: sex, age at diagnosis, therapy in the last ye...

Capillary hyperglycemia in critically ill infants is a situation with numerous interfering factors, from acute illnesses to concomitant use of medications and may or may not be a manifestation of endocrinological urgency. Clinical case: Female patient, 2 months old, with failure to thrive, hepatomegaly without cholestasis, polyuria and compensated metabolic acidosis. On admission, capillary blood glucose levels above 200 mg/dL were measured even without concomitant use of cort...
