A Novel AVPR2 Mutation (L161P) Causing Partial Nephrogenic Diabetes Insipidus

Yamashita Sumie , Hata Astuko , Kaneko Naoto , Usui Takeshi , Hata Daisuke

Background: Nephrogenic diabetes insipidus (NDI) is a disorder characterized by renal resistance to the antidiuretic effect of AVP. Affected patients are exhibiting symptoms as polyuria and polydipsia. Approximately 90% of congenital NDI are inherited in an X-linked recessive manner and caused by mutations of arginine vasopressin type 2 receptor (AVPR2) gene.Objective and hypotheses: An 8-year-old Japanese boy was referred to our hospital for nocturnal e...

Background: Data regarding epidemiology and management of Diabetic Ketoacidosis (DKA) in Italian children with T1D at disease onset are lacking.Method: From 1/1/2012 to 31/12/2013 a survey on DKA was conducted in all paediatric Centres belonging to the Italian Society for Pediatric Diabetology and Endocrinology. DKA was defined according to the ISPAD criteria. The following data were collected: treatment according ISPAD protocol yes or not, type of rehyd...

Specific Hypothalamic Activation Pattern by mGlu5 Receptor Blockade in vivo During Pubertal Development in Female Mice

Inta Ioana , de Angelis Roberto , Lankisch Katja , Dormann Christof , Pfeiffer Natascha , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: Puberty is characterised by important changes of brain networks. The glutamate system plays a main role in modulating the onset of puberty as shown for NMDA receptor agonists. However, the underlying mechanisms are poorly understood. Metabotropic mGlu5 receptors (mGluR5) are tightly linked to NMDA receptors. The effect of mGluR5 blockade on neurohormonal mechanisms in puberty initiation were not studied yet.Objective and hypotheses: To invest...

Use of Tolvaptan in a child with SIADH post pituitary surgery

Lohiya Nikhil , Didi Mohamed , Senniappan Senthil ,

Introduction: Post-operative management of fluid and electrolyte imbalance after surgery for pituitary or suprasellar tumors could be challenging. Post-operative course could include diabetes insipidus (DI) (transient or permanent) or a classical triphasic response (initial phase of DI followed by a second phase of transient SIADH and third and final phase of permanent DI). Mainstay of management of SIADH in these patients involves fluid restriction. At times,...

Atar Müge , Tan Aykut , Yetkin Ay Zuhal , Atar Müge , Pirgon Özgür

The aim of this study was to determine the periodontal health status in patients with Hashimoto thyroiditis (HT) and investigate the gingival groove fluid and saline oxidative stress parameters in order to demonstrate their relationship.Method: 30 patients between the ages of 11-17 years and 30 healthy volunteers aged between 10-17 years were included in the study. Serum tT4, TSH, anti-TPO, glucose, insulin, ALT, triglyceride, total chol...

Severe Hyponatremia and Repeated Intestinal Resections for Intestinal Dysmotility Mimicking Congenital Aganglionic Megacolon due to Delay in the Diagnosis of Congenital Hypothyroidism

Buyukyilmaz Gonul , Baltu Demet , Soyer Tutku , Tanyildiz Murat , Demirbilek Huseyin

Background: Congenital hypothyroidism (CH), the most common preventable cause of mental retardation in children, may presents with non-specific signs and symptoms. Beside, majority of the infants can be asymptomatic. Underestimation and/or misdiagnosis may cause delay in diagnosis and results in severe complications.Case report: A 5 months-old female admitted to our clinic with the history of repeated surgical operations due to the diagnosis of congenita...

Stimulated copeptin based diagnosis of central diabetes insipidus in children and adolescents

Gippert Sebastian , Choukair Daniela , Brune Maik , Bettendorf Markus

Introduction: Diagnosis of central diabetes insipidus (CDI) remains challenging. Water deprivation test and hypertonic saline infusion, as established diagnostic tests, are mentally and physically demanding for patients. Copeptin response to arginine-stimulation and insulin tolerance test (ITT) has been shown to be a putative parameter in the diagnosis of CDI in adults, but data are lacking for children and adolescents.Methods:</...

The effect of a GnRH analogue injection on the circulating levels of kisspeptin-1 in girls with suspected central precocious puberty

Rodanaki Maria , Rask Eva , Lodefalk Maria

Introduction: Kisspeptin stimulates the gonadotropin releasing hormone (GnRH) neurons in hypothalamus initiating puberty. However, it is not known whether GnRH inhibits kisspeptin secretion by negative feedback and whether there are any associations between circulating levels of kisspeptin and other hormones, like ghrelin, important for the onset of puberty.Methods: Thirteen girls with suspected central precocious pubert...
