P.H. Adriaansen Bas , oude-Alink Sandra , W. Swinkels Dorine , A.M. Schröder Mariska , N. Span Paul , C.G.J. Sweep Fred , L. Claahsen - van der Grinten Hedi , E. van Herwaarden Antonius

Background: Patients with congenital adrenal hyperplasia (CAH) might suffer from hyperandrogenism. For diagnosing and treatment monitoring, usually levels of androstenedione (A4) and testosterone (T) are measured in blood. More recently, adrenal-specific 11-oxygenated androgens such as 11- hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11KA4), 11-hydroxytestosterone (11OHT), and 11-ketotestosterone (11KT) were introduced as promising biomarkers, but ...

The Influence of Specimen pH on Urinary LH and FSH by Immunochemiluminometric Assays

Ma Ya-Ping , Xu Zhuang-Jian , Hu Yu , Zhu Wen-Ying , Wang Qing

Background: It remains unclear whether specimen pH can influence urinary LH and FSH assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen pH on urinary LH and FSH assayed by ICMA.Method: The first morning-voided urine were collected and divided into 11 samples (each 100 ml). The urine pH was determined with a pH meter. Hydrochloric acid and sodium hydroxide were added to al...

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 ...

Central or Primary Hypothyroidism? How to Differentiate in Patients with Low T4 but Mildly Elevated TSH Levels

Turan Serap , Gurbanov Ziya , Bas Serpil , Abali Saygin , Atay Zeynep , Bereket Abdullah

Background: Central hypothyroidism (CH) is caused by TSH and/or TRH deficiency leading to hypothyroxinemia with low, normal or mildly elevated TSH levels. Differentiation of CH with mildly elevated TSH levels from primary hypothyroidism (PH) can be difficult. However, this differentiation has important clinical implications (i.e. cortisol replacement before L-thyroxine).Objective and hypotheses: In this study, we constructed a nomogram all...

Treatment Adherence and Weight Loss are Key Predictors of HbA1c One Year after Diagnosis of Childhood Type 2 Diabetes in UK

Candler Toby , Mahmoud Osama , Lynn Richard , Majbar Abdalmonem , Barrett Timothy , Shield Julian PH

Background: Type 2 Diabetes (T2DM) is increasing in childhood especially among females and South-Asians.Objective: To report outcomes from a national cohort of children and adolescents with T2DM 1-year post diagnosis.Subjects and Methods: Clinician reported 1-year follow-up of a cohort of children (<17 years) with T2DM reported through British Paediatric Surveillance Unit (April 2015–April 2016). This followed the same met...

The Effect of Subclinical Hypothyroidism (SH) and Treatment of SH with L-T4 on Basal Metabolic Rate in Obese Children: A Prospective Study

Muzafferova Nigar , Bas Serpil , Atay Zeynep , Bereket Abdullah , Turan Serap

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...

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...

Body Proportions Estimated by Photometry

Gerver Willem Jan , Brecheisen Ralph , Penders Bas , Straetemans Saartje

Background: The growth process that transforms a newborn into an adult implies that there is not only an increase in height but above all a constant change in body proportions. Knowledge of the body proportions gives insight into the natural process of maturation and any disturbance can be used as a diagnostic tool.Objective and hypotheses: Manual measurement of body dimensions is a highly time-consuming procedure requiring a variety of measurement tools...

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...
