Introduction: Beckwith-Wiedemann syndrome (BWS) is a multisystem imprinting disorder. Approximately 50% of patients with BWS develop congenital hyperinsulinism (CHI). In this report, we describe the main clinical features in a group of patients with BWS and CHI.Study: Clinical and laboratory data was collected from all patients with BWS under the care of endocrine units at Alder Hey Children’s Hospital (Liverpool, UK) and Endocrine Research Centre (...

Background: Branchio-oto-renal (BOR) syndrome is a rare inheritable condition affecting the ears, 2nd branchial arch structures and the urinary system. Recognised features include hearing loss, structural defects of the ear, branchial defects, and a variety of renal malformations. Causative genetic variants have been identified as SIX1 and EYA1, accounting for approximately 49% of all cases of BOR syndrome. Short stature has not commonly been described in BOR syndrome, but is ...

Background: Paediatric HPAT, though generally benign, incurs significant neuro-endocrine morbidity. Their management is unclear and the paediatric neuro-oncology or adult pituitary forum at which they are discussed lack pituitary or age-specific expertise respectively. The UK National HPAT Interest Group has pioneered a monthly, multi-site, interdisciplinary, video conferencing decision-making forum, to garner necessary experience and evidence of outcomes to assist worldwide r...

Background: Klinefelter syndrome (XXY) is characterised by sex hormone aneuploidy. It is one the most common causes of primary hypogonadism, impaired spermatogenesis and testosterone deficiency. It affects around 1 in 500 phenotypic males. Approximately 25% of the patients are diagnosed in childhood. The hallmark of the condition is the small volume of the testicles and azoospermia. Most adolescent progress through puberty at the expense of elevated gonadotrophins.<p class...

Background: Anti-Mullerian hormone (AMH), secreted by immature Sertoli cells, provokes the regression of male fetal Mullerian ducts. Loss of function mutations in genes coding AMH (AMH) or its receptor (AMHRII) lead to the persistent Mullerian duct syndrome (PMDS) which is characterized by the presence of uterus, fallopian tubes, cervix and vagina in otherwise normally virilized 46,XY males. Typical clinical features along with plasma AMH levels and genotypin...

Introduction: Thyroid cancer is the most common pediatric endocrine cancer, constituting 0.5%–3% of all childhood malignancies. Cancer can be present in multinodular thyroid disease but the majority of malignant nodules are solitary. Thyroid malignancies in children are almost always well differentiated.Aim: Prevalence, clinical features, pathological profile and therapy of thyroid cancer in children.Patients and method: Retro...

Background: ACTH deficiency (ACTHD) is a potentially life-threatening condition observed in many childhood survivors of intracranial. Time from tumor diagnosis and therapy to development of ACTHD cannot be ascertained from previous studies. This lack of knowledge has led to annual surveillance using low-dose ACTH stimulation testing (LDST) for 10–15 years following completion of therapy.Objective and hypotheses: To identify the incidence and timing ...

Background: Carney complex (CC) is a rare, dominantly inherited condition due to mutations of the tumour suppressor gene PRKAR1A. Endocrine manifestations include: Cushing’s syndrome (CS) due to primary pigmented nodular adrenocortical disease, pituitary adenomas, testicular neoplasms, thyroid tumours, and ovarian cysts. The management of some of these tumours is controversial.Objective and hypotheses: To describe conservative management of CC.<...

Background: Due to the rarity of Paediatric Cushing’s disease (CD) there is limited data on the long-term consequences of treatment.Objective and hypotheses: We assessed recurrence, anterior pituitary function and psychiatric disorders in a group of paediatric CD patients treated in a single centre.Method: Retrospective review of 20 patients with CD, mean age 11.75 years (5.74–17.8), managed in our centre between 1986 and...

Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controls.Method: Prospective cross sectional study. 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) and 38 age and sex matched healthy controls underwent pQCT at 4, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as medi...
