Local Lipoatrophy following Recombinant Human Growth Hormone Administration in Prader Willi Syndrome

Akcan Nese , Bundak Ruveyde

Background: Recombinant human growth hormone (rhGH) is usually administered via subcutaneous injections. Besides well-known adverse events such as peripheral edema, benign intracranial hypertension, and slipped capital femoral epiphysis, a less known and rare side effect is local lipoatrophy, a phenomenon with an incompletely understood pathophysiology. Here, we report a case of Prader Willi Syndrome (PWS) who presented with local lipoatrophy following hGH.</p...

The Efficacy of Tri-ponderal Mass Index and Body Mass Index in Estimating Insulin Resistance, Hyperlipidemia and Impaired Liver Enzymes During Childhood and Adolescents

Akcan Nese , Obyed Moaaz , Salem Jana , Bundak Ruveyde

Body mass index (BMI) is used to diagnose obesity in children and adolescents. Recently, the tri-ponderal mass index (TMI) has been reported to be nearly stable throughout adolescence and estimate body fat levels more accurately than BMI especially in adolescents. Aim: To compare the efficacy of TMI and BMI in forecasting of insulin resistance, hyperlipidemia and impaired liver enzymes.Method: One hundred and forty-two overweight or obes...

A Patient with Multiple Endocrine Neoplasia Type 1 Presented with Precocious Puberty

Akcan Nese , Mousa Umut , Sav Hasan , Bundak Ruveyde

Background: Multiple Endocrine Neoplasia Type 1 (MEN1) is an autosomally transmitted hyperplastic or neoplastic disorders of some endocrine and non-endocrine organs. Pituiatry tumors develop in 30–70% of patients with MEN1. Mean age at onset of MEN1 associated pituitary tumors is the 4th decade and its occurence before and during puberty is very rare. Although there are two case reports about MEN1 and delay puberty, early and rapidly progressive puberty with MEN1 has no r...

Clinicopathological Characteristics of Papillary Thyroid Cancer in Children With Emphasis on the Pubertal Status and Association With BRAFV600E Mutation

Poyrazoglu Sukran , Bundak Ruveyde , Bas Firdevs , Darendeliler Feyza

Background: Papillary thyroid cancer (PTC) constitutes more than 90% of the thyroid cancer in children. PTC behaves differently in prepubertal children than in pubertal children and between children and adults. BRAF gene activating mutations lead to PTC by creating aberrant activation. The most common mutation is BRAFV600E.Objective and hypotheses: To evaluate clinicopathological characteristics of PTC patients with emphasis on the pubertal st...

Clinical Characteristics of 30 Patients with 45,X/46,XY Mosaicism

Poyrazoglu Sukran , Saka Nurcin , Bas Firdevs , Bundak Ruveyde , Darendeliler Feyza

Background: 45,X/46,XY mosaicism is associated with a broad spectrum of phenotypes, ranging from ambiguous genitalia at birth to patients with a completely male or female phenotype. Turner syndrome stigmata and associated anomalies could be found in these patients.Objective and hypotheses: To evaluate clinical presenting symptom and follow-up data of 30 patients with 45,X/46,XY karyotype.Method: Thirty patients with 45,X/46,XY mosa...

Onset of Puberty in Healthy Boys is Associated with a Decreased BMI Compared to Values Prior to the Onset of Puberty

Bundak Ruveyde , Darendeliler Feyza , Bas Firdevs , Poyrazoglu Sukran , Gunoz Hulya , Neyzi Olcay

Background: In several studies it has been shown that BMI influences the timing of puberty, mostly in girls, but has not been a consistent finding in boys.Objective and hypotheses: To investigate the association between BMI and timing of pubertal onset in a population based sample of Turkish boys.Method: Data on growth and pubertal development were collected by biannual visits to six primary and secondary level schools in Istanbul ...

Precocious Puberty in Patients with Primary Adrenal Insufficiency due to Melanocortın Receptor 2 Mutation

Bas Firdevs , Abali Zehra Yavas , Guran Tulay , Genens Mikayir , Poyrazoglu Sukran , Bundak Ruveyde , Darendeliler Feyza

Background: Precocious puberty has a complex and polygenic etiology. To describe genetic factors affecting onset and regulation of puberty and pathophysiology of precocious puberty, further studies are needed. Although, it is reported that ACTH receptor MC4R has impact on premature adrenarche, MC2R is expressed in the adrenal cortex and has a major role on the control of hypothalamo-pituitary-adrenal cortex. Melanocortin signaling system is reported to have l...

Effect of Gonadotropin Releasing Hormone Analogues (GnRHa) on Final Height in Girls with Borderline Early Puberty or Normal Physiological Puberty Depend on Bone Age Advancement and Predicted Height

Hizli Zeynep , Bas Firdevs , Poyrazoglu Sukran , Genens Mikail , Abali Zehra Yavas , Bundak Ruveyde , Darendeliler Feyza

Background: Borderline precocious and normal-onset puberty can show slow or fast course. The fast development of pubertal signs can be resulted in decrease in final height (FH) via accelerated growth and bone maturation.Objective and hypotheses: To study the effectiveness of GnRHa in improving FH in girls with advanced bone age (BA) and decreased predicted height (PH) in borderline early or normal physiological puberty.Method: 135 ...

Background: 3-M syndrome is an autosomal recessive growth disorder characterised by severe pre- and post-natal growth retardation caused by mutations in CUL7, OBSL1 or CCDC8. Clinical characteristics include dysmorphic facial features and fleshy prominent heels with a variable degree of radiological abnormalities.Objective and hypotheses: Evaluation of four new patients from two different families. Cases:Family-1/Patients-1,2: Two ...

Does Applying Regular Questionnaire to Patients on GH Increase the Compliance?

Genens Mikayir , Poyrazoglu Sukran , Sukur Mine , Bas Firdevs , Bundak Ruveyde , Darendeliler Feyza

Background: Compliance of patients on GH treatment is very important for the success of the treatment. In a multıcentre study done in Turkey we had shown that compliance decreased at the end of 1st year of treatment which had an adverse effect on growth rate and IGF1 levels.Objective and hypotheses: To evaluate whether doing regular questionnaire to patients on GH has an effect on compliance at long term.Method: A questionnair...
