Neuroendocrine Consequences of Hypothalamic Hamartoma and their Imaging (MRI) and Surgery Correlates

Corredor Beatriz , Caredda Elisabetta , Ederies Ash , Tisdall Martin , Cross Helen , Spoudeas Helen A.

Background: Hypothalamic hamartomas(HH) are rare heterotopic congenital malformations causing central precocious puberty(CPP) and/or resistant epilepsy whose natural history is unknown.Aim: To describe clinical and imaging features, and the risk of developing endocrine deficits, particularly after surgery.Method: Retrospective case note and imaging review of all HH diagnosed by MRI between 30.08.1991 and 24.11.17, analysed by initi...

Oxytocin Deficiency is Associated with Hyperphagia and Weight Gain in Hypothalamic and Common Obesity: A First-in-Humans Proof-of-Concept Study

Gan Hoong-Wei , Leeson Clare , Aitkenhead Helen , Spoudeas Helen , Martinez-Barbera Juan Pedro , Dattani Mehul

Background: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology has been attributed to hyperphagia and hyperinsulinaemia. The wider roles of oxytocin (OXT) in regulating appetite and weight have recently emerged in animal and human studies, but there is no human evidence that hypo-oxytocinaemia contributes to weight gain.Hypothesis: Hypo-oxytocina...

Hypothalamic Obesity, Hyperphagia, and Hyperinsulinaemia: Time for a Paradigm Shift in Assumptions?

Gan Hoong-Wei , Leeson Clare , Aitkenhead Helen , Spoudeas Helen , Dattani Mehul

Background: Hypothalamic obesity (HyOb) is a syndrome of inexorable, treatment-resistant obesity seen after congenital (e.g. septo-optic dysplasia (SOD)) or acquired (e.g. tumour-related) hypothalamic damage, often co-existing with hyperphagia, panhypopituitarism, autism, sleep, and temperature dysregulation. Its pathophysiology is poorly understood but hyperphagia and excess caloric intake may be less important than previously thought.Objective and hypo...

Neuroendocrine Morbidity after Paediatric Craniopharyngioma: a Longitudinal Single Centre Analysis of 93 Patients Over 30 Years

Dehalvi Shiraz , Guzzetti Chiara , Gan Hoong-Wei , Spoudeas Helen

Context: Craniopharyngiomas are rare, suprasellar tumours with excellent 5-year survival rates of 95%. Despite their benign histology, their tendency to invade vital nearby optic, hypothalamopituitary and vascular structures, complicates resection whilst potentially causing secondary life limiting morbidity, panhypopituitarism and premature mortality. Since 1997, conservative hypothalamic-sparing surgery and radiation to the residual tumour has replaced aggressive resection at...

Validation of an Automated Method (BoneXpert) for the Determination of Bone Age in Paediatric Endocrinology – A Single Centre Experience

Calder Alistair , Dastamani Antonia , Spoudeas Helen , Dattani Mehul

Background: The BoneXpert method is an automated determination of bone age, which employs deformable models of each bone to locate the bones, and extracts the component of the bone appearance related to maturity in a holistic, statistical manner. The BoneXpert has been validated on normal children and children with diagnoses typical of pediatric endocrinology. Multiple clinical studies suggested that BoneXpert has adequate accuracy, precision, and efficiency to be clinically u...

Pulling the Brakes – ‘Catch Down Growth’: A Phenomenon for Achieving Mid-parental Height Centile After Acquired, All-cause, Brain Injury

Kraus Fabian B T , Hindmarsh Peter C , Spoudeas Helen A

Introduction: Of any pituitary dysfunction following brain injury, growth hormone (GH) deficiency (GHD) is the most prevalent. The cut-point for defining GHD has been placed at 7 ng/mL representing optimum test performance. We hypothesised this cut-off may be set too low for genetically taller children with acquired brain injury, notably brain tumours, who demonstrate severe growth failure but repeatedly fail to meet diagnostic thresholds for GH replacement until several centi...

Subfertility After Chemotherapy in PNET Tumours: 34 year Experience from a Single Centre (1980–2013)

Serra-Caetano Joana , Pandalai Soumya , Phipps Kim , Spoudeas Helen Alexandra

Background: PanEuropean(SIOP) trials of treatment for childhood brain cancers (medulloblastomas/PNET) showed a 5% survival advantage with ‘sandwich’ gonadotoxic chemotherapy (CT) over surgical excision, neuraxial radiation and tumour boost (RT) alone. But this was tempered by a reduced quality of survival at 7 years.Objective: To assess the long term prevalence of subfertility after CT with/without neuraxial radiation.<p class="a...

Atypical Presentation of Six Patients with Mutations in the Side Chain Cleavage Enzyme CYP11A1

Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Endocrinopathy after Intracranial Germ Cell Tumours (IGCT) is Disease Not Radiation-Related: Two Decades of Surveillance in a Large Tertiary Paediatric Cohort

Dimitrakopoulou Eftychia Ioanna , Chow Jasmine , Spoudeas Helen , Ederies Ash

Background: Childhood IGCT are rare, malignant tumours of the pituitary stalk and pineal region, highly curable (>90%) by multimodal therapies. Neuroendocrine outcomes are thus important. Deficits increase over time but, without longitudinal studies, it remains unclear whether they are primarily disease or treatment related.Objective and hypotheses: To determine, by longitudinal retrospective analysis in survivors, tumour- and treatment-related facto...

Growth Outcomes in Childhood Craniopharyngioma: A Longitudinal Assessment of 21 Cases at a Single Centre

Michaelidou Maria , Losa Laura , Ederies Ashraf , Spoudeas Helen

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 ...
