Background: Thyroid dysfunction is a common condition in children and has been associated with metabolic syndrome, hypertension, cardiovascular disease and mortality. Due to the obesity epidemic in paediatric population exists a higher prevalence of nonalcoholic fatty liver disease (NAFLD), a condition associated with insulin resistance and metabolic syndrome. In adults it has been observed that elevated TSH, even within the normal range, are positively correlated with increas...

The genomic analysis of 46,XX individuals with testes (known as testicular Disorders/Differences of Sex Development (TDSD) or ovotestes (ovotesticular DSD (OTDSD)) supports the hypothesis that ‘pro-testis/anti-ovary’ or ‘pro-ovary/anti-testis’ genetic pathways exist. These children typically present with virilized genitalia due to testosterone production from the presence of testicular tissue. Many individuals with TDSD and a minority with OTDSD have a tran...

Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...

Background: Chromosome analysis is always indicated in disorders of sex development (DSD), but the need for karyotyping in gender dysphoria (GD) is less clear.Aims and objectives: We therefore aimed to review the place of routine chromosome analysis in the management of GD in children and adolescents.Patients and methods: 490 children and adolescents with GD have been referred to the two endocrine clinics forming part of the joint ...

Background: Iodine concentrations in Chilean schoolchildren are the highest in South America. This may be related to excessive sodium intake, which is associated with hypertension. However, iodine decreases blood pressure (BP), which would be a cardiovascular protective factor.Objective and hypotheses: The objective of this study is to evaluate the effects of iodine on BP and cardiovascular risk factors, despite salt intake.Method:...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

Introduction: The 46,XX testicular disorder of sex development (DSD) is a rare genetic condition and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients, but approximately 20% of patients are SRY-negative. We report a 1.3 -year old SRY/negative 46,XX boy with complete sex reversal caused by SOX3 duplication.Case report:...

Introduction: The increasing prevalence of obesity has become a major global health issue. Clustering of cardiometabolic risk factors in obese adolescents is associated with reduced life expectancy and impaired quality of life. Due to serious impact of obesity on cardiometabolic health, effective treatment strategies are intensively sought after.Objectives: The aim of this retrospective cross-sectional study was to exami...

Background: Over the last 25 years more than 410 cases with suspected Familial Glucocorticoid Deficiency (FGD) have been referred to our centre for genetic testing. All cases had low or undetectable serum cortisol paired with an elevated plasma ACTH level. Our patient cohort comprises 352 families from 30 different nationalities and ranges from neonates to patients in their eighties. Mutations in the MC2R were first discovered as causative of FGD in 1...

Introduction: Morphological characteristics of the glucose concentration curve during an oral glucose tolerance test (OGTT) may reflect differences in insulin secretion and sensitivity. Whether the shape of the glucose curve and time to peak glucose concentration can be used as indicators of beta cell function and markers of type 2 diabetes risk in obese adolecents is still uncertain.Aims/hypothesis: The purpose of this cross-sectional study was to asses...
