No Difference in Cognitive Performance or Gender Role Behaviour in Men with and without Hypospadias

Strandqvist Anna , Ortqvist Lisa , Frisen Louise , Nordenskjold Agneta , Herlitz Agneta , Nordenstrom Anna

Background: Hypospadias is a common malformation of male external genitalia, resulting in urethral displacement with different severity. Male genital development occurs during fetal development when also the brain is developing rapidly. Genital development is dependent on androgen effect, and androgens also have impact on gender development. We here explore whether hypospadias are associated with variation in other aspects of sex typical development.<p c...

Significant Penile Growth with Local DHT-Gel in an Infant with 17-Beta HSD-Deficiency

Halldin Stenlid Maria , Nordenskjold Agneta , Frisen Louise , Svensson Johan , Lajic Svetlana , Nordenstrom Anna

We demonstrate significant penile growth in an infant with 17 beta HSD-deficiency treated with DHT-gel.Background: The child was born with ambiguous genitalia at full term. Investigations revealed 46,XY karyotype, testosterone and DHT levels were 2.5 nmol/L and <0.1 nmol/L respectively. No female internal genitalia were found. hCG stimulation did not result in an increase in testosterone, but a clinically obvious increase in phallus size. Subsequent ...

Are Heterozygous Carriers of CYP21A2 Less Vulnerable to Psychological Stress?

Nordenstrom Anna , Butwicka Agnieszka , Falhammar Henrik , Hirschberg Angelica Linden , Almqvist Catharina , Nordenskjold Agneta , Frisen Louise

Background: Congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000, and even more common in some populations. Do carriers have a survival advantage?Objective and hypotheses: The HPA axis has been reported to be more active in CYP21A2 carriers, and possibly enable a more rapid return to homeostasis. A compensatory increase in CRH s...

Carriers of CYP21A2 Mutations have Decreased Mortality in Infectious Diseases, Anational Population Registry Study

Nordenstrom Anna , Svensson Johan , Lajic Svetlana , Frisen Louise , Nordenskjold Agneta , Norrby Christina , Almqvist Malmros Catarina , Falhammar Henrik

Background: Congenital adrenal hyperplasia (CAH) is a relatively common monogenic recessive disorder with an incidence of 1/15 000 in most populations. It has been suggested that CYP21A2 deficiency is relatively common because it may confer a survival advantage to be a carrier. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype. The cortisol response to ACTH stimulation has been shown to be both...

Hyperinsulinaemic Hypoglycaemia: A New Presentation of 16p11.2 Duplication Syndrome

Conwell Louise , Flanagan Sarah

Introduction: De novo and inherited cases of 16p11.2 microdeletion and duplication syndromes have a spectrum of clinical manifestations, with incomplete penetrance and variable expressivity.16p11.2 copy number variants have shared phenotypic features (autism, developmental delay). Mirror phenotypes have also been described: deletions – obesity, hyperphagia, macrocephaly; duplications – underweight, feeding/eating disor...

A study on the Complications associated with Severe Obesity in Children and Young People

Apperley Louise , Senniappan Senthil ,

Introduction: The complications of obesity are well recognised and documented in the adult population. There is little data available that reports the complications of childhood obesity seen in clinical practice. The aim of our study is to investigate the different types of complications seen in children and young people (CYP) with obesity.Methods: 125 CYP aged 0-18 years who had a body mass index (BMI) standard deviatio...

Socioeconomic Deprivation is Associated with Increased Hospital Admissions in Children with Type 1 Diabetes Mellitus

Apperley Louise , Ng Sze May

Background: Socioeconomic deprivation is an important determinant of health.Objectives: This study examined the relationship between incidence of hospital admissions for patients with Type 1 diabetes mellitus (T1DM) and their socioeconomic deprivation.Methods: All hospital admissions of patients with T1DM from 0 to16 years were identified during a 5-year period between 2007 and 2012 using the hospital episodes statistics database (...

Household Unemployment and Low Levels of Education are Associated with Poor Glycaemic Control in Children and Young People with Type 1 Diabetes Mellitus

Apperley Louise , Ng Sze May

Background: Socioeconomic deprivation, obesity and emotional well-being are important determinants of health inequalities and poor glycaemic control in adults with type 1 diabetes mellitus (T1DM).Objectives: This study aims to look at the effect of social deprivation, BMI and patient reported emotional well-being on glycaemic control in children and young adults with T1DM.Methods: Socioeconomic status was measured by cross-referenc...

Are you considering Idiopathic Intracranial Hypertension when evaluating a patient with obesity?

Apperley Louise , Kumar Ram , Senniappan Senthil ,

Introduction: Obesity is a recognised risk factor for raised intracranial pressure in the adult population but is still under-recognised in children and young people. The pathophysiology of raised intracranial pressure in relation to obesity remains unclear. The aim of our study is to investigate the association between idiopathic intracranial hypertension (IIH) and obesity in children and young people.Method: Patients d...

Phenotypic Characterization of a Large Pediatric Cohort of Patients with Genetic Forms of Congenital Hypopituitarism

Cionna Cecilia , Cerbone Manuela , Gregory Louise C , Dattani Mehul T

Background: Genetic variants are identified in a small proportion (~10%) of patients with Congenital Hypopituitarism (CH), with variable associated phenotypes. We aimed to phenotypically characterise a large cohort of patients with genetically proven CH.Patients and methods: 1684 CH patients were screened (Sanger or whole exome sequencing) over a 20-year period (1998-2018) for mutations in genes regulating pitui...
