Background: Silver Russell syndrome (SRS) is a heterogeneous disorder characterised by intrauterine and post-natal growth retardation, relative macrocephaly, protruding forehead, feeding difficulties and body asymmetry. Variants in HMGA2 are a rare cause of SRS and despite strong evidence for the crucial role of HMGA2 in growth regulation, its functional role in human linear growth is unclear.Methods: Patients w...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

Gärskog Helena , Mattsson Mattias , Lundberg Elena

Background: Adrenocortical Carcinoma (ACC) represents 0.16% of all pediatric neoplasm in children, 0-14.9 years, diagnosed between 1984-2010 according to Swedish Childhood Cancer Registry. ACC is most frequent in girls below 4 years of age.Case: A physically active 14 years old girl was referred due to growth velocity 0 cm over the last year. Her history revealed substantial weight gain (photos), pubertal arrest prem...

A Rare Cause of SRY (-) 46, XX DSD: Aromatase Deficiency

Buğrul Fuat , Güran Tülay

Introduction: Aromatase deficiency is a rare cause of autosomal recessive 46, XX disorders of sex development (DSD) due to CYP19A1 gene mutations. The affected patients cannot have a normal estrogen biosynthesis. It is characterized by low serum estrogen, increased gonadotropins, and ovarian cysts. Herein, we report a new case with aromatase deficiency.Case Report: A 1-month-old girl was referred due to cliterom...

Metabolic Parameters and Glucose Homeostasis in Childhood Onset Growth Hormone Deficiency at Time of Initial Evaluation and Retesting

Ahmid M , McMillan M , Ahmed S F , Shaikh M G

Background: It is well known that growth hormone (GH) brings about several effects, involving bone, body composition, lipids and glucose homeostasis. However, the complex interplay between these parameters is rather poorly studied in children with childhood-onset-GH deficiency (CO-GHD).Objective and hypotheses: To investigate lipids, adipokines (leptin- adiponectin- resistin) and glucose homeostasis and their relationship with bone and body composition i...

Development of Pubertal Gynaecomastia: a Longitudinal Cohort Study

Mieritz Mikkel G , Hagen Casper P , Juul Anders

Background: Pubertal gynaecomastia (PG) is considered a clinical sign of an oestrogen–androgen imbalance at the breast tissue level although little evidence exists. PG occurs in 40–60% of adolescent Caucasian boys, and in most cases however, no underlying endocrinopathy can be identified. Very few longitudinal studies on PG exist.Objective and method: As a part of the longitudinal COPENHAGEN Puberty Study we followed 110 healthy Danish boys (ag...

The Relationship Between Serum Neurotensin Levels and Metabolic Parameters and Eating Behavior in Obese Children

Tuncerler Gülten , Özyurt Gonca , Uzun Hamide , Çalan Özlem Gürsoy , Küme Tuncay , Dündar Bumin Nuri , Çatli Gönül

Introduction: Neurotensin is a 13 amino acid peptide with central and intestinal effects. It has been shown to decrease intestinal and gastric motility, increase the absorption of fat by regulating the release of pancreas and bile acid. In addition, it is reported that there is also an anorexigenic effect of the neurotensin released from the central nervous system. In the literature, conflicting results related to serum / plasma neurotensin levels were reporte...

Introduction: Thyroid cancers are rare cancers in children and their incidence is 1.4% in pediatric malignancies. However, its frequency is increasing. While the incidence of prepubertal children is equal among girls boys, it increases with age in female patients. Radiotherapy, which is applied to the neck region, and hashimoto disease are the risk factors. The relationship between Hashimoto's disease and papillary thyroid cancer is thought to be assoc...

Adherence with Twice-Monthly, At-Home Dosing Schedule of Somavaratan (VRS-317) Long-Acting Growth Hormone Treatment in Children with Growth Hormone Deficiency (GHD) (NCT02068521)

Humphriss Eric , Sheikh F. Naureen , Seaman Morgan , Ng David , Bright George

Background: Treatment adherence to daily subcutaneous rhGH is a burden for GHD patients, with noncompliance reported in up to 77% of patients and significantly associated with reduced efficacy (Rosenfeld Endocr Pract 2008; Cutfield PLoS One 2011). Somavaratan, a novel rhGH fusion protein with t1/2 >100 h, demonstrated clinically meaningful improvements in height velocity and IGF-I in prepubertal children with GH deficiency (GHD) in a multicenter, randomized, Pha...

Introduction: Gonadal insufficiency is a common long-term endocrinological complication of BMT and is mainly associated with the chemotherapy protocol. In the literature, gonadal insufficiency after BMT varies between 66% -80% in girls and 35-60% in boysAim: to investigate the frequency and the factors affecting gonadal insufficiency in cases with BMT due to non-malignant indications in children or adolescenc...
