Concurrent premature gonadotrophic activation and gonadal insufficiency in young girls with a brain tumor

Evelein Annemieke , Schouten - Van Meeteren Netteke , Bakker Boudewijn , Gidding Corrie , Van der Wetering Marianne , Van Santen Hanneke

Background: It is well known that endocrine comorbidities occur frequently in children with cancer, especially in those with a brain tumor. In those children, increased intracranial pressure or hydrocephalus may lead to central precocious puberty. Furthermore, chemotherapy, especially alkylating agents, increases the risk for gonadal insufficiency. In this case series we describe 3 young girls with a brain tumor, who develop premature gonadotrophic activation,...

Pediatric Patients with Heterozygous ALPL Mutation show a Broad Clinical Phenotype

Melanie Brichta Corinna , Wurm Michael , Krebs Andreas , Lausch Ekkehart , Van der Werf-Grohmann Natascha , Schwab Karl Otfried

Introduction: Hypophosphatasia (HPP) is a congenital disorder of the bone and mineral metabolism. It is based on mutations in the ALPL gene, which codes for tissue-unspecific alkaline phosphatase (TNSAP). Methods:The casuistic of 3 children with heterozygous ALPL mutation are presented. The patients were identified by laboratory data screening for reduced AP activity at the Children's Hospital of the University Hospital Freiburg....

Sertoli-Leydig Cell Tumor as a Rare Cause of Hirsutism in a Young Adolescent

van der Straaten Saskia , Merckx Mireille , Van Dorpe Jo , Goethals Inge , Bordon Victoria , Timmers Philippe , De Schepper Jean

Background: Sertoli-Leydig Cell Tumors (SLCT) account only for 1% of all ovarian neoplasia, occur more commonly in the second or third decade of life and seldom secrete tumor markers. The experience in adolescence is limited.Objective and hypothesis: To report the hormonal and biological profile of a SCLT in a young adolescent. Ovarian tumor markers as well as FDG-PET scanning might be helpful in diagnosing ovarian malignancy in case of normal ultrasound...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Cortisol evaluation in 106 neonates born from mothers using corticosteroids during pregnancy. Proposal for practical approach in clinical practice.

Snijder P.M. , Brandsma AE , van Wijk CAM , Baartmans MGA , van der Heyden JC , van den Akker ELT , Sas TCJ

Context: Supra-physiological exogenous corticosteroids used during the last months of pregnancy may lead to temporary neonatal adrenal suppression. Little is known about the outcome of neonates from mothers who used corticosteroids during pregnancy.Objective: The evaluation of clinical symptoms and biochemical findings of adrenal suppression in neonates from mothers using corticosteroids during pregnancy.<p class="ab...

Absence of Central Adrenal Insufficiency in Adults with Prader-Willi Syndrome

Rosenberg Anna , Davidse Kirsten , Pellikaan Karlijn , Donze Stephany , Hokken-Koelega Anita , van der Lely Aart Jan , de Graaff Laura

Introduction: Individuals with Prader-Willi syndrome (PWS) suffer from hyperphagia, hypotonia and hypothalamic dysfunction, leading to a variety of pituitary hormone deficiencies. Central adrenal insufficiency (CAI) has been reported in PWS, while each of these studies used different testing modalities and cut-off values. Therefore, reported prevalence of CAI ranges from 0% to 60%. It has been speculated that CAI might be responsible, at least in part,...

A Simulation-based Intervention Teaching Illness Management Skills to Caregivers of Children with Adrenal Insufficiency: a Randomised Controlled Study

Virtanen Heidi , Pyra Eileen , Schawrz Wendy , Catena Helen , Cripps Amy , Grant Vincent , Cheng Adam , Perry Rebecca

Background: Permanent adrenal insufficiency (AI) is an uncommon but potentially life-threatening condition in children. Patients are at particular risk during times of stress. Thus, caregivers should have good illness management skills. Despite frequent teaching and seemingly good knowledge of illness management we still see a reluctance of caregivers to administer intramuscular (IM) hydrocortisone at home when indicated, preferring instead to drive themselves...

Effects and Side Effects of Cyproterone Acetate Alone and in Combination with Estrogens in Natal Male Adolescents with Gender Dysphoria

Tack Lloyd , Craen Margarita , Dhondt Karlien , Bossche Heidi Vanden , Laridaen Jolien , Cools Martine

Background: Male to female (MtF) gender dysphoric adolescents with advanced pubertal development can be treated with antiandrogenic progestins such as cyproterone acetate (CA). CA is much cheaper and easier to administer than GnRHa and can later be combined with cross-sex hormones (17β-estradiol) (CA+E). To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To report the effects of consecutive CA a...

Bone Health in a Cohort of Irish Spinal Muscular Atrophy Patients

Mc Sweeney Niamh , Mc Kenna Malachi , Webb David , van der Kamp Susan , Kilbane Mark , O' Keane Myra , Lynch Bryan

Background: Spinal Muscular Atrophy (SMA) is characterised by progressive muscle weakness, resulting from loss of anterior horn cells in the spinal cord and the brain stem nuclei. Survival motor neuron levels (SMN) are reduced due to mutations in the SMN1 gene. SMN function has been implicated in poor bone health. SMA is classified according to age of onset and clinical course accordingly: type 0 (prenatal), type 1 (onset <6 months, severe, never sit unsupported), type 2 (...

The effects of dextroamphetamine treatment in children with hypothalamic obesity

Samaan J , Welling MS , de Groot CJ , Abawi O , Burghard M , Kleinendorst L , van der Voorn B , van Haelst MM , Oude Ophuis B , Kamp GA , Rotteveel J , van Schouten-Meeteren AYN , van den Akker ELT , van Santen HM ,

Introduction: Children with hypothalamic dysfunction, e.g. due to a genetic or acquired cause such as suprasellar tumours, often suffer from hyperphagia and/or decreased resting energy expenditure (REE). This process induces uncontrollable weight gain, resulting in severe hypothalamic obesity (HO). No effective treatment is available yet for HO. Amphetamines are psychostimulants that are known for their appetite reducing and REE stimulating side effects. Here,...
