Background: Craniopharyngiomas are rare suprasellar tumours with good survival but high endocrine morbidity. The commonest endocrinopathy is GHd which can precede diagnosis. Later obesity (BMI >+2SDS) may be treatment or tumour related.Objective and hypotheses: To evaluate endocrinopathy, height, weight and BMI outcomes after a conservative surgical treatment strategy with pre-treatment pituitary provocation tests for children diagnosed between 2009 ...

Background: The HPAT multi-disciplinary meeting (MDT) was set up in 2011 with the aim to improve collaboration with other hospitals treating children with rare paediatric suprasellar brain tumours. It is a monthly remote meeting conducted virtually.Objective: To evaluate the impact of COVID19 pandemic by comparing the number of meetings, cases (news/previously discussed), diagnosis, attendees, specialties, centres and ou...

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...

Introduction: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology is incompletely understood, with weight gain being attributed to hyperphagia and hyperinsulinaemia. We sought to compare the physiology of various plasma appetite-regulating hormones in HyOb and ‘simple’ obesity (Ob) to improve our understanding of both forms of obesity and identify novel therap...

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...

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...

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...

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...

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...

Background: We previously reported in a national cohort, that adherence to subcutaneous Growth Hormone (GH) treatment in children is better with jet delivery compared with needle devices (Spoudeas et al. Patient Prefer Adherence. 2014;8:1255–1263). We also separately reported that adherent children showed significantly improved height outcomes at one year.Objective and hypotheses: To examine the potential influence of adherence and demograp...
