Systemic Pseudohypoaldosteronism Type 1 Due to 3 Novel Mutations in SCNN1A and SCNN1B Genes; Report of 3 Cases

Cayir Atilla , Demirelli Yasar , Yildiz Duran , Kahveci Hasan , Yarali Oguzhan , Karaoglan Dogus Vuralli , Kurnaz Erdal , Demirbilek Huseyin

Objective: The systemic form pseudohypoaldosteronism type 1 (PHA1) is an autosomal recessive disorder characterized with defective sodium transport in many organ systems including kidney, lungs, colon, sweat glands and salivary glands. Homozygous or compound heterozygous loss-of-function mutations in the genes encoding amiloride sensitive epithelial sodium channel (ENaC) account for genetic causes of systemic PHA1.Case 1: Male patient presented with vomi...

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...

A Rare Cause of Diabetes Insipidus: Congenital Proprotein Convertase 1/3 Deficiency

Karaguzel Gulay , Cakir Murat , Akbulut Ulas , Janecke Andreas , Okten Aysenur

Background: Proprotein convertase 1/3 (PC1/3) deficiency, an autosomal-recessive disorder caused by rare mutations in the proprotein convertase subtilisin/kexin type 1 (PCSK1) gene, has been associated with severe malabsorptive diarrhea and certain endocrine abnormalities.Objective and hypotheses: To date, only 13 subjects with PC1/3 deficiency have been reported, now we want to report a new patient who was diagnosed PC1/3 deficiency with novel PCSK1 mut...

Does Vitamin D Affect Mean Platelet Volume Values or Not

Bulan Keziban , Dogan Murat , Kaba Sultan , Aslan Oktay

Objective: Platelets play a key role in the development and progression of cardiovascular disease. The degree of platelet activation may be assessed by platelet indices such as platelet count, mean platelet volume (MPV) and platelet distribution width (PDW). In addition, both epidemiological and in-vitro studies have linked vitamin D deficiency to enigmatic disease including cardiovascular disease however a clear mechanistic link remains missing. In present study, we ...

Relationship Between Adenoid Vegetation and Neurosecretory Dysfunction (Pituitary Dysfunction)

Dogan Murat , Bulan Keziban , Kaba Sultan , Garca Fatih

Introduction: The role of enlarged adenoid tissue has been long discussed in terms of causes leading obstructive sleep apnea. Sleep disorders in children with adenoid vegetation impair quality and duration of REM sleep where GH secretion is higher. We also thought that cortisol that displays a circadian rhythm might be also affected by sleep disorders. For this purpose, we planned to determine presence of neurosecretory dysfunction (NSD), time and level of cortisol peak in the...

Royal Jelly Supplementation Induces the Growth Plate Development and Increases Plasma Growth Hormone and Oestradiol Levels in Prepubertal Rats

Sever Murat , Pirgon Ozgur , Ciris Metin , Aydin Bunyamin

Background: In recent years families, especially in the children’s growth and development, often use alternative treatments as growing more healthy individuals.Objective and hypotheses: The purpose of the present study was to examine the hormonal, histomorphometric and immunohistochemical effects of Royal Jelly (RJ), which was a growth supplement commonly used by parents for their children, on growth plate of young rats.Method...

Utility of Estimated Glucose Disposal Rate and Fat Mass Percentage for Predicting Metabolic Syndrome in Children and Adolescents with Type 1 Diabetes

Koken Ozlem , Kara Cengiz , Yilmaz Gulay Can , Aydin Murat

Objective: To determine the prevalence of metabolic syndrome (MetS) and the clinical utility of fat mass percentage (%fat) and estimated glucose disposal rate (eGDR) for predicting MetS in children and adolescents with type 1 diabetes (T1D).Method: We conducted a descriptive, cross sectional study including T1D patients between 8–18 years of age. Modified criteria of IDF, WHO and NCEP were used to determine the prevalence of MetS. eGDR, a validated ...

A Prospective Evaluation of Anthropometric and Metabolic Profile Premature Adrenarche Patients

Karabulut Gulcan Seymen , Imal Murat , Cizmecioglu Filiz Mine , Hatun Sukru

Background: Premature adrenarche (PA) is defined as the appearance of pubic and/or axillary hair before 8 years in girls and 9 years in boys.Objective and hypotheses: We aimed to evaluate the anthropometric measures, hormonal values of children with PA at time of diagnosis, distinguishing the patients with late onset congenital adrenal hyperplasia and to analyse the components of insulin resistance, obesity, hyperlipidemia, metabolic syndrome, menstrual ...

Deleting STX16 exon 4 to understand the genetic mechanisms underlying pseudohypoparathyroidism-1B and GNAS imprinting

AKSU CAGRI , Reyes Monica , Remillard Claire , He Qing , Bastepe Murat ,

Autosomal dominant pseudohypoparathyroidism type-Ib is characterized by renal parathyroid hormone resistance, with resultant hypocalcemia and hyperphosphatemia. This disorder is associated with an isolated loss of methylation at GNAS exon A/B and most patients carry maternal microdeletions in the neighboring STX16 gene. The shortest deletion overlap is a 1.2-kb region spanning STX16 exon 4 and thought to harbor a cis-acting element regulating GNAS A/B methylation. However, abl...
