Background: The heterozygous mutation in the SRCAP gene (611421) on chromosome 16p11.2 causes a rare genetic disorder named Floating–Harbor syndrome (FHS). The clinical diagnosis of FHS is characterized by a triad of short stature with significantly delayed bone age; expressive language delay, usually in the presence of normal motor development; and a triangular face with prominent nose and deep-set eyes.Objective: To investigate the presence of SRC...

Background: Endocrine disruptors (ED) are chemicals that can mimic hormones and interfere with their receptors, causing endocrinological abnormalities.Clinical report: We present the case of a previously healthy, melanodermic, two-year-old female, who had a three-month evolution of clitoromegaly and generalized hypertrichosis. Endocrine blood work showed suppressed serum androgens suggesting steroid exogenous contact. Karyotype, bone age...

Background: Paediatric nephrotic syndrome has an estimated incidence of 2 per 100,000 children per year and type 1 diabetes had a reported incidence of 9.5 per 100,000 habitants in Portugal (2018 data). To the best of our knowledge, the simultaneous occurrence of nephrotic syndrome and type 1 diabetes is rare – we found 13 published cases in paediatric age worldwide. Clinical case: A 5-year-old boy with personal history of nephrotic syndrome was admitted ...

Background: Multiple Endocrine Neoplasia type 1 (MEN-1) is a rare and underdiagnosed syndrome caused by inactivating mutations of the tumor suppressor gene MEN-1 that predisposes to multiple tumors classically situated in the anterior Pituitary, Parathyroid, and Pancreas. The mutation is transmitted in an autosomal dominant way, and for this reason, the screening of all first-degree relatives is mandatory afte...

Background: The WDR11 gene was recently involved in the pathogenesis of isolated hypogonadotropic hypogonadism (IHH). In 2010, Kim et al. (1) identified five different heterozygous missense WDR11 rare variants in six of 201 IHH patients (five normosmic IHH and one Kallmann syndrome), which were absent in more than 400 controls. Animal studies demonstrated that WDR11 interacts with EMX1, a homeodomain transcription factor involved in the development of olfacto...

Background: We present a 17-year-old female who presented with a 1 year history of hirsutism, male pattern baldness, marked cystic acne and mild cliteromegaly. She had her menarche at the age of 15 years and continued thereon to have a regular menstrual cycle. She was pubertal on examination (B3, P5, A5) with no neurological deficit.Objective and hypotheses: This female presented with marked clinical hyperandrogenism. We initially suspected polycystic ov...

11-year-old female, admitted in the emergency room due to postprandial hyperglycemia (350 mg/dL) in her father´s glucometer without ketosis or acidosis. She referred one-month evolution of mild symptoms, as polydipsia, polyuria, sporadic abdominal pain and nocturia.She was the first child of non-consanguineous parents, born full term at vaginal delivery with a birth weight of 3760g (90th percentile). Since 5-years-old her weight was betwe...

Introduction: Differentiation of the external genitalia depends on serum androgen concentrations in the foetal life. The classic form of Congenital Adrenal Hyperplasia due to 21-hydroxylase deficiency (21OHD) is the most frequent cause of female genital ambiguity. It is an autosomal recessive disorder due to CYP21A2 mutations that are classified in groups based on their in vitro residual enzymatic activity. The phenotype usually is predicted by the less severe mutatio...

Background: Aortic sized index (ASI) defined as aortic root size/body surface area (BSA) is used to provide information on dissection risk in Turner Syndrome (TS). There are multiple equations for estimation of BSA. The impact of using a different BSA equation for calculation of ASI is unknown.Method: We calculated BSA of 114 TS girls from 2273 outpatient visits using Dubois, Mostellar, Haycock, Gehan, Boyd and Furqan formulae. BSA estimation with Dubois...

Introduction: Thyroid disorders are the second commonest endocrine dysfunctions encounter in pregnancy after Diabetes. These include overt hypothyroidism, overt hyperthyroidism, subclinical hypothyroidism and subclinical hyperthyroidism. Pregnancy has profound impact on the thyroid gland and thyroid functions (TF). Failure to adapt to these physiological changes result in abnormal TF and cause adverse foetal and neonatal outcomes like miscarriages, placental a...
