Hyperinsulinemic Hypoglycemia in Congenital Disorder of Glycosylation Type-1a (CDG-1a)

Vuralli Dogus , Yildiz Yilmaz , Serap Sivri H. , Alikasifoglu Ayfer

Introduction: Congenital disorder of glycosylation type-1a is a multi-system disease involving neurological, gastrointestinal, ophthalmologic, cardiac or endocrine systems. In addition to hypothyroidism and hypergonadotropic hypogonadism, rare occurrences of hyperinsulinemic hypoglycemia in CDG patients have been reported. In the present report, we describe a patient diagnosed with CDG type-1a accompanied by hyperinsulinemic hypoglycemia, and whose responsive to diazoxide....

Management of Gonads in Adults with Androgen Insensitivity: An International Survey

Maris Ellen , Looijenga L H J , Cools Martine

Background: Individuals with androgen insensitivity syndrome (AIS) have an increased risk for developing a germ cell cancer (GCC). The risk is low during childhood; therefore, gonads are commonly preserved until after puberty. Little is known about GCC development in AIS during adulthood. This question is particularly relevant as many adult AIS women decline gonadectomy.Objective and hypotheses: To gain insight in attitudes towards gonadectomy in various...

Turner Syndrome in Iceland 1968–2012: Congenital Anomalies and Clinical Outcomes

Sigmarsdottir Arndis A , Johannsson Johann H , Sigurjonsdottir Helga A , Thorsson Arni V

Background: In 1968 a cytogenetics laboratory was established at the University Hospital, Reykjavik and has since then served as the only chromosomal laboratory for all hospitals and physicians in Iceland. Our current aim was to study the physical features, congenital anomalies and various clinical outcomes in Icelandic females, diagnosed with Turner syndrome (TS) for the period of 1968–2012.Method: Data was obtained from hospital records, from all ...

Ontogenesis of the urinary steroid metabolome in infancy assessed by gas chromatography/mass spectrometry (GC-MS)

Rakicioglu H , Pons-Kuehnemann J , Hartmann M , A. Wudy S

Introduction: The steroid metabolism of the newborn and infant is subject to rapid changes and is extremely difficult and complex to assess. Of all analytical techniques, the platform technology of GC-MS allows the most comprehensive assessment of the entire steroid metabolome and this approach is also non-invasive.Method: In order to characterize the essential changes in steroid metabolism during infancy, a total of 355...

Serum AMH Levels are Lower in Healthy Boys Who Develop Pubertal Gynaecomastia

Mieritz Mikkel G , Hagen Casper P , Almstrup Kristian , Petersen Jorgen H , Raket Lars L , Sommer Stefan H , Juul Anders

Background: Pubertal gynaecomastia is thought to be a clinical sign of an oestrogen-androgen imbalance, affecting up to 60% of boys. In most cases no underlying endocrinopathy can be identified. In boys, Anti-müllerian hormone (AMH) is produced by immature Sertoli cells and circulating level decreases as testosterone increases during pubertal maturation. In a previous cross sectional study we found significant lower levels of AMH in boys with pubertal gynaecomastia (Mieri...

Recombinant Growth Hormone Therapy in Prepubertal Children with Idiopathic Short Stature in Korea: A Phase III Randomized Trial

Im Minji , Kim J , Suh B-K , Ko CW , Lee K-H , Shin CH , Hwang JS , Kim HS , Chung WY , Kim CJ , Han H-S , Kwon NY , Cho SY , Yoo H-W , Jin D-K

Several studies have evaluated the effects of growth hormone (GH) on auxological and biochemical parameters in children with non-GH-deficient, idiopathic short stature (ISS). This study evaluated the efficacy and safety of GrowtropinR-II (recombinant human GH) in Korean patients with ISS. This was a 1-year, open-label, multicenter, phase III randomized trial of Growtropin-II in Korean patients with ISS. In total, 70 prepubertal subjects (39 males, 31 females) betwee...

Cardiomyocyte Glucocorticoid and Mineralocorticoid Receptors Antagonistically Regulate Heart Disease

Oakley Robert H , Cruz-Topete Diana , He Bo , Foley Julie F , Myers Page H , Willis Monte S , Gomez-Sanchez Celso E , Chambo Pierre , Cidlowski John A

Stress is increasingly associated with cardiac disease. Glucocorticoids are primary stress hormones that regulate homeostasis through two nuclear receptors, the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Cardiomyocytes express both receptors but little is known concerning their specific and coordinated actions in heart physiology and pathology. To examine the in vivo function of glucocorticoid signaling in the heart, we generated mice with cardi...

The effect of common genetic variants in CYP19A1 on serum Estradiol to Testosterone Ratio in healthy Danish children and adolescents

L. R. Groendahl Veronica , A. Holmboe Stine , S. Busch Alexander , Aksglaede Lise , P. Hagen Casper , H. Johannsen Trine , H. Petersen Jørgen , Almstrup Kristian , Frederiksen Hanne , Juul Anders

Background and Aim: Despite the broad individual variation of pubertal maturation, references traditionally describe growth in relation to just chronological age and not biological age. Hence, growth references for the adolescent period have been of limited usefulness for monitoring individual growth in clinic and for research. Especially for children and adolescents with chronic diseases is there a need to better evaluate if changes in SD-scores just before a...

Treatment-resistant hypokalemia and arterial hypertension: a prismatic case of low renin childhood hypertension

Rakicioglu H. , Kamrath C. , Genthner N. , Karatsiolis P. , Reincke M. , A. wudy S.

We report on a 17-year-old female patient with cramps in hands and legs since 6 months. She showed hypokalemia with high need of potassium substitution (128mmol K= 1.3 mmol/kg/d), arterial hypertension (mean 154.5/92 mmHg), polydipsia and polyuria without nocturia or salt craving. Her PMH revealed neuroblastoma stage III with high-dose chemotherapy, stem cell transplantation and obesity (36.8 kg/m2). Further investigation showed aldosterone 77.5 ng/dl (norm values: 2-10ng/dl),...

Diagnostic and management practices of girls presenting with polycystic ovary syndrome (PCOS)-like symptoms to a tertiary paediatric endocrine clinic.

Solanas Martín Blanca , R. Howard Sasha , R. Hughes Claire , L. Storr Helen , H. Willemsen Ruben

Background: Polycystic ovary syndrome (PCOS) continues to be a diagnostic challenge in adolescent girls. Symptoms like oligomenorrhea and acne, and polycystic ovarian morphology on ultrasound can be normal variants in adolescents. In addition to diagnostic difficulties, there is lack of randomized controlled trials for PCOS treatments specific to adolescents. Current guidelines for diagnosis and management of PCOS in adolescents have large variations and rely ...
