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...

Delayed Puberty in A 16-Year-Old Male Associated with Gamma Aminobutyric Acid Capsule Supplements

Blackburn James , Senniappan Senthil , Ahmed Syed Harris

Background: Delayed puberty is defined as the absence of physical signs of puberty 2 to 2.5 standard deviations greater than the mean and affects 2% of the adolescent population. We present a male patient aged 16, presenting with delayed puberty. On direct questioning the patient revealed he had been taking regular Gamma-Aminobutyric Acid (GABA). These supplements appeared to suppress the hypothalamic-pituitary-gonadal (HPG) axis.<st...

Isolated Premature Menarche into Two Siblings with Neurofibromatosis Type 1

Blackburn James , Didi Mohammed , Senniappan Senthil

Background: Neurofibromatosis type 1(NF1) is an autosomal dominant genetic disorder caused by NF1 mutation. The condition is typified by the development of benign and malignant tumours in both the central nervous system and peripheral tissues. We present two siblings diagnosed with NF1 who presented at an early age with isolated menarche.Case Presentation: Sibling 1 – A 7-year-old patient w...

Thyroid Hormone Receptor β (THRB) Mutation: Two New Cases of Heterozygous Mutation with Significant Family History

Blackburn James , Senniappan Senthil , Giri Dinesh

Introduction: Resistance to thyroid hormone (RTH) is a relatively uncommon disorder that is usually associated with mutations in thyroid hormone receptor (THR) beta, although rarely THR alpha mutations have been described. RTH beta (RTHB) is often inherited in an autosomal dominant pattern. We describe two cases of RTHB to highlight the significant variations in both clinical presentation and family history.Case 1: A 2 year old patient ...

Incidence and risk factors for paediatric diabetic retinopathy: case control for a tertiary hospital in Leeds, United Kingdom

Hester Holly , Adams Elizabeth , Kelleher Aoife , Yong James , Campbell Fiona

Introduction: Diabetic retinopathy is a leading microvascular complication and preventable cause of vision loss. NHS diabetes eye screening program (DESP) assesses for early signs, with population prevalence between 3.5% and 24.2%. Understanding the factors involved is important to reduce morbidity.Aims and objectives: Establish clinical characteristics and modifiable risk factors for patients with retinopathy identified...

Novel Mutations in GLIS3/TRMT10a As A Cause Of Congenital Hyperinsulinism

Krishnamurthy Mansa , Deng Lily , Lozano Claudia , Kraus Jonathan , Wells James

Introduction: Congenital hyperinsulinism (CHI) is a heterogeneous group of disorders characterized by hypoglycemia and inappropriate insulin secretion. Prompt identification of CHI and its genetic causes are essential to minimize the risk of permanent neurological damage as well as guide treatment options for these patients. Although, there are 15 known monogenic forms of CHI, there remain 50% of patients without an identified genetic diagnosis, suggesting tha...

Prevalence and Factors Associated with Hypothyroidism in Children with Sickle Cell Anemia Aged 6 Months -17 Years Attending the Sickle Cell Clinic, Mulago Hospital, Mg anda; A cross-sectional study

Kaudha Gloria , Musiime Victor , Piloya Thereza , Kiguli Sarah , Tumwine James

Background: Sickle cell anemia (SCA) leads to chronic end organ damage including the thyroid gland. This is postulated to be due to recurrent hemolysis leading to iron overload, vaso-occlusive crises, micro-vasculature obstruction due to red cell entrapment and frequent transfusions. Some studies have demonstrated a relationship between hypothyroidism and SCA with a prevalence of 6% in children and adolescents. Hypothyroidism may affect brain and physical deve...

Identification of X-linked Adrenoleukodystrophy in Boys Presenting with Adrenal Insufficiency in the Absence of Adrenal Antibodies

Ryalls Michael , Gan Hoong-Wei , Biedenkapp Joe , Davison James

Adrenoleukodystrophy (ALD) is an X-linked, metabolic disorder caused by genetic deficiency of peroxisomal ALD protein resulting in accumulation of very-long chain fatty acids (VLCFA) primarily in the adrenal cortex and central nervous system. Approximately 35–40% of boys with ALD develop cerebral ALD (CALD), which causes rapidly progressive cerebral demyelination, loss of neurologic function, and death. Disease progress can be halted by allogeneic hematopoietic cell trans...

The British OsteoNEcrosis Study: A Multi-centre Prospective Study

Amin Nadia , James Beki , Feltbower Richard , Mushtaq Talat , Kinsey Sally

Introduction: Osteonecrosis can be a debilitating consequence of treatment for acute lymphoblastic leukaemia (ALL), most commonly affecting patients aged between 10 and 20 years at diagnosis of malignancy. Patients may have asymptomatic lesions that spontaneously regress, and little is known about the natural history of lesions. There is also limited understanding of the relationship between osteonecrosis and other markers of bone health.Aims: The aims o...

Atypical Hepatoblastoma and Wilm’s Tumour in an Infant with Beckwith-Wiedemann Syndrome and Diazoxide Resistant Congenital Hyperinsulinism

Uppal Saurabh , Senniappan Senthil , Didi Mohammad , Hayden James

Introduction: Beckwith-Wiedemann Syndrome (BWS) is a rare genetic disorder that could be associated with embryonal tumours. Genotype based categorisation of patients enables better screening strategies. We present a patient with BWS who developed atypical congenital hepatoblastoma and atypical Wilms tumour in infancy.Case Report: A 2 day old infant was referred with recurrent hypoglycaemia and high intravenous glucose requirement [>12 mg/kg/min]. He ...
