National UK Guidelines for the Clinical Assessment, Diagnosis, Treatment and Follow-up of Children and Young People (CYP) Under 19 Years of Age with Phaeochromocytoma (PCC) and Paraganglioma (PGL) – On Behalf of the UK Paediatric Phaeochromocytoma and Paraganglioma Guideline Development Group (GDG)

Katugampola Harshini , Marks Stephen , Quek Samuel , Yadav Prateek , Spoudeas Helen A , Harrison Barney

Background: PCC and PGL are rare in CYP. National children’s registry data reveal an annual incidence of 0.2 and 0.3 per million in 5–9 and 10–14 year age groups respectively. Almost all result from a genetic predisposition, can present with non-specific symptoms, and represent a significant management challenge.Aims: We aimed to provide the first interdisciplinary national management guidelines using the AGREEII framework for CYP with con...

Glucocorticoid Deficiency Causes Differentially Dysregulated Oxidative Stress Depending on the Steroidogenic Defects

Li Nan , Weger Meltem , Griffin Aliesha , Eachus Helen , Cunliffe Vincent T , Krone Nils

Glucocorticoids regulate a wide range of biological processes including metabolism. Patients with adrenal insufficiency show impaired glucocorticoid biosynthesis either caused by adrenal defects (primary adrenal insufficiency) or by defects in the pituitary gland or hypothalamus (secondary or tertiary adrenal insufficiency). The systemic consequences of differentially disrupted steroid hormone biosynthesis remain unclear. Increasing evidence suggested steroid hormone precursor...

Bone Biochemistry in Children with Fractures Presenting with Suspected Non-accidental Injury

Forbes Owen , McNeilly Jane , McDevitt Helen , Houston James , Ahmed S. Faisal , Mason Avril

Introduction: Fractures have been recorded in up to one third of children who have suffered from physical abuse. The British Paediatric and Adolescent Bone Group (BPABG) position statement on vitamin D states that the level of 25 hydroxyvitamin D is not relevant to causation of fractures unless there is radiological or biochemical evidence of rickets. Clinicians are often asked in the court setting about the relevance of abnormal serum investigations in children who have fract...

A Novel p.Gly775Glu Missense COL1A2 Mutation Causes Severe Osteogenesis Imperfecta in a Prepubertal Girl

Kotanidou Eleni P , Doulgeraki Artemis , Costantini Alice , Makitie Outi , Athanasopoulou Helen , Laliotis Nikolaos , Galli-Tsinopoulou Assimina

Background: Osteogenesis imperfecta (OI) due to COL1A1 and COL1A2 mutations is the most common cause of primary osteoporosis.Case presentation: We present a 10-year-old girl with a history of skeletal fragility, starting in the perinatal period. Her parents are not consanguineous and there is no family history of early osteoporosis. To date, she has sustained nineteen low-energy, long bone fractures and she has skeletal deformities (leg length discrepanc...

Long Term Reversibility of Presumed ACTH Deficiency (ACTHd) in Children and Young People (CYP) with Intracranial Germ Cell Tumours (IGCT)

Pieri Kyriaki , Michaelidou Maria , Chatoo Zaynab , Holloway Ross , Dastamani Antonia , Spoudeas Helen A

Introduction: ACTHd is life-threatening and difficult to differentiate from ACTH suppression (ACTHs) especially in CYP receiving perioperative corticosteroids. In our experience, this is always the most robust anterior pituitary hormone to brain injury, whilst GH deficiency (GHd) is the first and LH/FSHd and TSHd intermediate in hierarchy. We previously showed HPA axis recovery at 3.08 (2.38–10.33) years after cortiscosteroid therapy for ACTHd in 13.6% of 44 CYP with cran...

A Single Centre Experience of Managing a Series of Childhood Macro/Giant-Prolactinoma

Dastamani Antonia , Bulwer Chloe , Ederies Adhraf , Jeelani Owase , Fersht Naomi , Aquilina Kristian , Korbonits Marta , Spoudeas Helen

Introduction: Childhood prolactinomas often occur as aggressive macro (1–4 cm) or giant (>4 cm) tumours, with little consensus regarding timing of optimal therapies.Aim: To highlight the phenotype and treatment outcome of childhood macroprolactinomas.Subjects and methods: Case-note review of 10 (five male) children (<18 years) (presenting to our centre between 2009 and 2017 with hyperprolactinaemia due to macro/giant-p...

A National UK Guideline for Managing Pituitary Adenomas in Children and Young People Under 19 Years Developed According to the AGREE II Framework

Blair Jo , Korbonits Marta , Ronaldson Amy , Dang Mary N , Spoudeas Helen

Pituitary adenomas are usually benign tumours arising from the hormone-secreting cells of the anterior pituitary gland. These adenomas can result in excess hormone secretion and the development of characteristic syndromes, such as Cushing’s disease, acromegaly and hyperprolactinaemia, and/or mass effects on surrounding vital structures causing for example visual disturbances and pituitary hormone deficiencies. In children and young people under 19 years (CYP), the managem...

Invasive Macroprolactinoma with Cabergoline Induced Cerebrospinal Fluid Rhinorrhoea in Childhood

Dastamani Antonia , Ederies Ashraf , Aquilina Kristian , Dorward Neil , Korbonits Marta , Spoudeas Helen

Background: Nonsurgical development of nasal cerebrospinal fluid (CSF) leaks may occur in the setting of pituitary adenomas, especially following a favorable response of invasive prolactinomas to initiation of Dopamine Agonist (DA) therapy, but this has not previously described in children.Case description: A girl of Srilankan origin, aged 13.8 years, whose parents spoke no English, presented with headaches and secondary amenorrhea. Pituitary MRI reveale...

Clinical and Endocrinological Manifestations of Partial Ectopic Posterior Pituitary: A New Imaging Entity

Ybarra Marina , Hafiz Rawan , Robinson Marie-Eve , Oettingen Julia von , Bui Helen , Saint-Martin Christine

Objective: To describe six cases of possible partial ectopic posterior pituitary gland (PEPP) seen on head magnetic resonance imaging (MRI) and their associated clinical and endocrinological manifestations.Methods: This is a single-center case series, from a tertiary public university health center in Montreal, Canada. Cases of children with possible PEPP were selected prospectively from 2005 to 2017, based on head MRI findings. Medical history, exam fi...

Endocrinopathy in Childhood Intracranial Germ Cell Tumours is Predicted by Disease Location not Treatment: 30 year Experience from a Single Tertiary Centre

Serra-Caetano Joana , Dimitrakopoulou Eftychia , Ederies Ash , Phipps Kim , Spoudeas Helen Alexandra

Background: Childhood pineal and/or suprasellar intracranial germ cell tumours (IGCT) are highly curable (>90%) with neuraxial radiation alone; international (SIOP) trials have aimed to decrease late radiation-induced neuroendocrine morbidity by substituting chemotherapy. However, without longitudinal study, disease and treatment contributions to long term outcomes remain unknown.Objective: To define tumour and treatment factors implicated in neuroen...
