Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

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...

Targeted gene panel screening in 144 congenital hypopituitarism patients, incorporating 135 known and novel genes implicated in hypopituitarism and/or hypothalamo-pituitary development.

Gregory Louise , Dattani Mehul

Congenital hypopituitarism (CH) is a highly variable disorder affecting 1:3000 - 1:4000 live births, and is characterized by deficiencies in one or more of the 7 pituitary hormones, with growth hormone (GH) being the most frequently-occurring deficiency. It may be associated with a range of syndromic features including visual impairment, midline brain abnormalities and facial clefting. The development of the pituitary gland is closely associated with that of the forebrain and ...

The effect of lifestyle intervention on glycaemic variation, quality of life and satiety levels in children and young people with obesity

Apperley Louise , Senniappan Senthil

Introduction: Childhood obesity is associated with pre-diabetes and type 2 diabetes mellitus. The gold standard investigation for these is an oral glucose tolerance test (OGTT). The aim of our study is to investigate glycaemic dysregulation in children and young people (CYP) with obesity using continuous glucose monitoring (CGM) and evaluate the effect of intense lifestyle intervention on various complications.Methods: 3...

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 (...

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...
