Introduction: In the pediatric age group, the incidence of the adrenocortical cancer (ACC) is 0.2%. The effective treatment is surgical resection. The only medical option is mitotane but it has negative effects on steroidogenesis. The difficulty in the management of mitotane therapy is discussed in this case.Case report: An 1110/12 years-old boy was referred with A 5 cm diameter solid-hypoecoic mass observed by sonography in the left surrenal ...

β-hCG from an Occult Source Causing Peripheral Precocious Puberty: Identification of the Tumour 6 Years After Presentation

Ekberzade Azad , Abali Saygin , Atay Zeynep , Bas Serpil , Gurbanov Ziya , Turan Serap , Guran Tulay , Bereket Abdullah

Background: β-hCG secreting germ-cell tumors (β-hCG-ST) are rare causes of Peripheral precocious puberty (PPP) in boys and usually located in intracranial region. Liver, retroperitoneum, testis and mediastinal cavity are the other localizations reflecting embryonic germ cell sites.Objective and hypotheses: We present a patient with PPP due to elevated β-hCG levels, but extensive efforts to find the source of elevated β-hCG was unrevea...

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 ...

Basal Levels of FSH and LH can be Helpfull in Diagnosis of Puberty Precocious?

Gul Ulku , Samur Bahadir , Tatlı Zeynep Uzan , Hatipoglu Nihal , Kendirci Mustafa , Kurtoglu Selim

Background: Luteinizing hormone stimulating hormone (LHRH) test is the gold standard test in the diagnosis of puberty precocıous (PP). The basal levels of FSH (follicular stimulating hormone) and LH (luteinizing hormone) cannot be always reliable.Objective and hypotheses: To investigate the relation between the LHRH test and basal levels of FSH and LH.Method: Girls with puberty started before the age 8 are investigated. Eighty...

In Patients with Chronic Autoimmune Thyroiditis, Investigation of the Effects of Functions of Regulatory T Cells and Vitamin D

Siklar Zeynep , Karatas Deniz , Dogu Figen , Kocaay Pinar , Hacihamdioglu Bulent , Ikinciogullari Aydan , Berberoglu Merih

Background: Treg cells are characterized by expression of Foxp3 molecule that serve as keys in the maintenance of peripheral tolerance and in controlling the immune response. The exact role of Treg cells in the pathogenesis of CAT has not been recognized yet.Objective and hypotheses: It is suggested that vitamin D is one of the factors that can regulate the function of Treg cells. In this study, the relationship between Treg cells (levels and expression)...

Genotype–Phenotype Discordant Patients with Homozygous Intron 2 Mutation (IVS2) of CYP21 Gene

Camtosun Emine , Siklar Zeynep , Ruhi Hatice Ilgin , Kutlay Nukhet Yurur , Kocaay Pinar , Tukun Ajlan , Berberoglu Merih

Background: 21-Hydroylase deficiency is the most common cause of congenital adrenal hyperplasia (CAH) and resulted from CYP21 gene mutations. Genotype and phenotype are usually concordant. Homozygous intron 2 splice mutation (IVS2/IVS2) is frequently associated with severe enzyme deficit, and causes classical CAH. Here, we present genotype–phenotype discordant members of two different families with IVS2/IVS2 mutation.Family 1: First child of family ...

GAD Antibody Positivity is Associated with Higher Prevalence of Autoimmune Thyroiditis in Children with Type 1 Diabetes Mellitus

Abali Saygin , Celik Enes , Haliloglu Belma , Bas Serpil , Atay Zeynep , Turan Serap , Bereket Abdullah

Background: The prevalence of autoimmune thyroid disease is higher in children with type 1 diabetes mellitus (T1DM).Objective and hypotheses: The aim of this study is to compare the frequency of autoimmune thyroiditis in children with T1DM according to the presence of diabetes autoantibodies.Method: This study included 533 (49% female) children with T1DM based on hospital records from a single center. Frequency of glutamic acid dec...

Objective and hypotheses: To answer the question of whether the age of diabetes onset is shifting to younger ages and whether the rate of DKA at presentation has changed over the 15 years in children with T1DM.Method: Patients with T1DM from a single center for Pediatric Endocrinology and Diabetes in Turkey since 1999 were included. In a period of 15 years, 517 patients (249 females) were divided into three groups due to the year of diabetes diagnosed (g...

Background: Aromatase inhibitors (AI) are being used in clinical trials in children related to peripheral precocious puberty, and idiopathic short stature to improve height prognosis.Case report: A 2 11/12 year-old boy was referred to our center for evaluation of penile enlargement and pubic hair development. Physical examination revealed a well-developed muscular boy with a body weight of 22 kg (>97p), height of 110.1 cm (>97p), with ...
