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...

Idiopathic Central Precocious Puberty on the Rise: A Retrospective Study Before and During the COVID-19 Pandemic in a Portuguese Tertiary-Level Hospital

Miguel Resende Maria , Gomes Pereira Patrícia , Mendes Catarina , João Oliveira Maria , Borges Teresa , Freitas Joana

Background and Aims: In light of the recent evidence suggesting an increase in idiopathic central precocious puberty (ICPP) cases during the COVID-19 pandemic, this study aimed to assess the proportion of patients referred for precocious puberty (PP) and, within this group, the number of ICPP cases diagnosed before and during the pandemic. Additionally, we compared the demographic, anthropometric, and clinical characteristics of ICPP patients between the two g...

Ovotesticular Disorder of Sexual Development Diagnosed in Adolescence – a Twins Case Report

Coelho Isabel , Soto-Maior Costa Maria , Kay Teresa , Patena Forte Joana , Cardoso Dinorah , Lopes Lurdes , Galhardo ulia

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...

Alterations in glucocorticoid metabolism as a possible cause of hypertension in childhood obesity

Martijn JJ Finken , JG Wirix Aleid , A von Rosenstiel-Jadoul Ines , van der Voorn Bibian , JM Chinapaw Mai , F Hartmann Michaela , E Kist-van Holthe Joana , A Wudy Stefan , Rotteveel Joost

Introduction: Childhood obesity is associated with alterations in hypothalamus-pituitary-adrenal axis activity. We tested the hypothesis that multiple alterations in the metabolism of glucocorticoids are required for the development of hypertension in children who become overweight.Methods: Timed spot urine for targeted gas chromatography-mass spectrometry steroid metabolome analysis was collected from (1) overweight/hyp...

Associations Between Pituitary Abnormalities and Treatment Response in Children with Growth Hormone Deficiency. First Multicenter Study in Portugal

Diamantino Catarina , Sofia Simões Ana , Borges Catarina , Costa Carla , Pereira Carla , Vieira Paula , Luísa Leite Ana , Cristina Monteiro Ana , Freitas Joana , Martins Sandrina , Teresa Bernardo Maria , Fonseca Marcelo , Mirante Alice

Background/Aims: Magnetic resonance imaging (MRI) is used to investigate the etiology of growth hormone deficiency (GHD). There is a close relationship between structural changes in the pituitary gland and clinical status.We aimed to investigate the relationship between MRI findings and clinical symptoms and treatment response in children with GHD.Methods: The study was conducted in nine Department...

Primary hyperparathyroidism due to a deletion of the CDC73 gene.

de Beldjenna Liliana Mejia , Garcia Castano Alejandro , Gomez Conde Sara , Castano Luis ,

Introduction: Primary hyperparathyroidism (PHPT), often caused by a single adenoma (80%–85%) or hyperplasia or adenomas involving multiple glands, is the major cause of hypercalcemia. PHPT is common and occurs in individuals of all ages, but its prevalence is lower in young adults. Parathyroid tumors and PHPT can be caused by germline (hereditary PHPT) or somatic mutations of tumor suppressor genes (e.g., multiple endocrine neoplasia type 1 and CDC73) and...

Permanent Neonatal Diabetes by Gene Mutation KCNJ11. Evolution and Treatment after Three Years with Sulphonylureas

Angeles Santos Mata Maria , Fernandez Viseras Irene , Torres Barea Isabel , Jose Macias Lopez Francisco , Catano Luis

Background: Permanent neonatal diabetes (PND)with heterozygous mutations of KCNJ11, respond to treatment with sulphonylureas. We report a case of PND in a baby, and mother previously mis-diagnosed with Type 1 DM. Both were switched from insulin to oral sulphonylureas. We evaluate the response and evolution.Case report: A male newborn at 37 weeks’ gestation, with a birthweight 2750 g (40thC) and length 48 cm (40thC), was admitte...

Congenital Hypothyroidism and Tuberous Sclerosis: an Association or a Coincidence?

Gallo Francesco , Conte Pietro , Alfano Rosa Maria , Bulfamante Gaetano , Moramarco Fulvio

Background: Tuberous sclerosis (TS) is a polymorphic, dominantly inherited syndrome caused by an inactivating mutation in tumor suppressor genes, TSC1 or TSC2; they regulate mammalian target of rapamycin (mTOR), a key player in control of cellular growth and protein synthesis. The disease involves benign tumors in several distinct organs (such as the skin, kidneys, heart, and CNS), that can interfere with organ function. Rarely TS is associated with endocrine abnormalities, an...

Transient Neonatal Diabetes Mellitus due to not Described Mutation in ABCC8 Gene with Different Behaviour in Affected Family Members

Angeles Santos Mata Maria , Pilar Fernandez Viseras Irene , Torres Barea Isabel , Castano Gonzalez Luis

Neonatal diabetes (ND), classified as either permanent (PND) or transient (TND), occurs in 1/200,000 live births. In 50% cases of TND, remission presents within the first year of life, only to relapse later before puberty in 50% of cases. The most frequent cause is mutation of the 6q24 gene accompanied by mutations in heterozygosis of ABCC8 gene. 80% of mutations in this gene are in novo, due to autosomal recessive inheritance. Such cases respond to treatment with sulfonylurea...
