The current lifestyle, with a diet increasingly removed from the Mediterranean diet, together with the habitual sedentary lifestyle, is associated with many of the so-called non-communicable diseases, such as the metabolic syndrome. Every day these pathologies are more frequent in pediatrics, so this study has tried to establish the prevalence of metabolic syndrome and its components in overweight and obese children and assess its impact. METHODS A descriptive study has been c...

Introduction: The influence of sex chromosomes and sex hormones on early human brain development is still poorly understood. Expression of Y chromosome genes may influence aspects of brain maturation in the 46,XY fetus, but the contribution of different Y genes is unknown. Furthermore, a marked increase in testicular testosterone biosynthesis/release from the testis occurs at around 8 weeks post conception (wpc) in the 46,XY fetus, but it is unclear whether te...

Background: Turner syndrome (TS) arises from a complete or partial loss of one X chromosome (45,X) and is the most common genetic cause of primary ovarian insufficiency (POI) in women. Surprisingly little is understood about the pathogenesis of POI in TS beyond an acknowledged germ cell loss throughout the second trimester. Although X chromosome haploinsufficiency likely contributes, the variability in reproductive phenotype in 45,X TS suggests it is not the o...

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...

Background: The sonic hedgehog pathway (SHH) regulates CNS development and mutations or abnormal expression of the SHH pathway genes have been identified in epithelial tumors. SHH pathway interacts with Wnt/β-catenin signalling. To date, CTNNB1/β-catenin mutations are the sole molecular abnormality found in adamantinomatous craniopharyngiomas (ACPs).Objective and Hypotheses: To analyze the expression pattern of SHH pathway genes in ACPs and its...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Background: In 2020, the average glycaemic index of Type 1 diabetes (T1D) in Southeast Asia (SEA) countries were reported to be at around 83mmol/mol. In many low-middle-income countries (LMICs) in SEA, insufficient infrastructure, lack of universal health coverage and professional knowledge are factors that affect T1D outcomes that adversely affect mortality and morbidity. Action4diabetes (A4D) currently provides comprehensive partnership programmes with defin...

Background: Sitosterolemia, a rare autosomal recessive defect in lipid metabolism, is caused by mutations in the transporter genes ABCG5 and ABCG8 coding receptors on the luminal surface of enterocytes. Thus, hyperabsorption of non-digestible plant sterol in tissue and blood resulting in cardiovascular (CVD) sequalae. Here we report a case of Sitosterolaemia incidentally diagnosed on whole exome sequencing (WES) for bony lesions in a young Saudi girl with asym...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...
