Background: Van Wyk-Grumbach syndrome (VWGS) is a rare diagnosis that should be suspected in children with signs of peripheral precocious puberty and hypothyroidism. It is characterized by multicystic enlarged ovaries, in the presence of long-term severe hypothyroidism. Treatment of VWGS consists of hormonal replacement with levothyroxine. Usually, ovarian cysts and increased ovarian volume subside within an average of 2 months but can persist up to 12 months after treatment.<...

Introduction: Maturity Onset Diabetes of the Young (MODY) is clinically and genetically heterogeneous type of Monogenic Diabetes (MD) and to date 14 genes have been associated with different MODY subtypes. It is a rare disease characterized by early onset hyperglycemia, autosomal dominant inheritance, and defect in β cell insulin secretion, often misclassified as T1DM or T2DM.Materials and Methods: Genetic analysis ...

Hypothyroidism in a Child During Treatment with Nivolumab for a Glioblastoma

H Birkebaek Niels , Dahl Christine

Objective: The programmed cell death 1 protein (PD1) is a T lymphocyte membrane receptor, which when bound to its ligand PD – L1 inactivates the cytotoxic T lymphocyte, thereby down regulating the immune response. Cancer may upregulate PD – L1 on the cell surface, further downregulating the immune response. Nivolumab, a so called check point inhibitor, is a PD1 antibody, and when bound to PD1 keep the cytotoxic T lymphocyte active. Cytotoxic T lymphocyte activation b...

Introduction: Pituitary adenoma (PA) in childhood is a rare disease, accounting for 3 % of all intracranial paediatric neoplasm, and between 3 to 6% of all PA. There are only few large studies describing paediatric pituitary adenoma and even fewer studies with long-term outcome.Methods: In this retrospective study, clinical, biochemical and radiological parameters and outcome of paediatric patients (<16 years...

Transition for Patients with Chronic Thyroid Diseases

Ratnasabapathy Piriya , Bouthors Thérèse , Antoniou Maria-Christina , Stoppa-Vaucher Sophie , Elowe-Gruau Eglantine , Busiah Kanetee , Hauschild Michael

Background: Children and adults with chronic thyroid disorders (TD) need continuous monitoring as periods of inadequate thyroid hormone substitution can impact metabolism, puberty and fertility. Transition from pediatric to adult-oriented care is often characterized by discontinuity in care resulting in poor health outcomes and impaired quality of life. Transition care (TC) for young adults with TD remains largely unknown.Objecti...

Rohhad Syndrome: Report of 2 Rare Cases From Crete-Greece

Smyrnaki Pinelopi , Chrysoulaki Maria , Daraki Vasiliki , Betsi Grigoria , Sfakiotaki Maria , Floroskoufi Paraskevi , Bouki Katerina , Kofteridis Diamandis , Kanaka-Gantenbein Christina , Xekouki Paraskevi

Introduction: ROHHAD syndrome (Rapid-onset Obesity with Hypoventilation, hypothalamic and autonomic dysregulation) is a rare and complex disease with potential fatal outcome. To this day there have been 158 cases reported in the literature while whole exome sequencing has not yet revealed any responsible genes. It usually presents at the age of 2-4 years and the diagnosis is based on the following criteria: 1) rapidly progressive obesity that develops at the a...

ZFP57-associated Transient Neonatal Diabetes is Responsive to Oral Sulfonylurea Treatment

Reinauer Christina , Jonasson Annemarie , Harmsen Stefani , Debinski Pierre , Soditt Volker , van Afferden Sonia , Mayatepek Ertan , Bergmann Carsten , Meissner Thomas , Kummer Sebastian

Background: Transient neonatal diabetes (TNDM) is commonly caused by a methylation loss in the 6q24 region, either in isolation or as multiple-loci demethylation due to ZFP57 gene mutation. TNDM is biphasic; usually resolves after 2–3 months but often recurs between age 4 and late adolescence.Case: The boy was born at 38 weeks of gestation (birth weight 3340 g, healthy consanguineous Turkish parents, unremarkable pregnancy). He presented at...

HERV-W-Env Protein Expression in Pediatric Type 1 Diabetes Patients

Bouthors Therese , Elowe-Gruau Eglantine , Diaz-Escagedo Patricia , Antoniou Maria-Christina , Stoppa-Vaucher Sophie , Levet Sandrine , Medina Julie , Demolder Amandine , Perron Herve , Hauschild Michael

Introduction: The envelope protein of Human Endogenous Retrovirus type W (HERV-W-Env) has been shown to be associated with type 1 diabetes (T1D) pathogenesis in adults patients. This protein is expressed in pancreas of T1D patients and it seems to correlate with macrophage infiltrations. In vitro and in vivo studies have demonstrated that HERV-W-Env inhibits insulin secretion and promotes hyperglycemia. Furthermore, HERV could be implicated in other auto-immune disorders. The ...

Lessons from Wolfram Syndrome: Initiation of DDAVP Therapy Causes Renal Salt Wasting due to Elevated ANP Levels, Rescued by Fludrocortisone Treatment

Background-Hypothesis: Sudden initiation of treatment for diabetes insipidus (DI) with DDAVP causes abrupt volume expansion resulting in particularly high secretion of Atrial Natriuteric Peptide (ANP) (1). ANP blocks all stimulators of zona glomerulosa steroidogenesis, resulting in secondary mineralocorticoid deficiency and acute hyponatremia, causing renal salt wasting (RSW) (2). Cases: Two sisters, a 19-year-old girl (A) and a 7-year-old girl (B) with Wolfra...
