Background: Gonadotropin independent precocious puberty (GIPP) is caused by a heterogenous group of disorders. With the exception of congenital adrenal hyperplasia (CAH), disorders causing GIPP are uncommon, and there are no studies evaluating the etiologic distribution of GIPP in a large cohort.Objective and hypotheses: To find out the relative frequencies of each etiological group in patients with non-CAH GIPP and also to evaluate the clinical and labo...

Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...

Background: Menarche is the endpoint of a complex sequence of maturational events but is the unique marker of female puberty. Timing of menarche is a strongly heritable trait. However, secular trends suggest that lifestyle and/or environmental factors are important.Objective: To assess the trend in age at menarche (AAM) in Istanbul over the last 12 years, and compare the patterns according to socioeconomic status (SES), ...

Introduction: Ceratonia siliqua L. (CS) is from the legumes (Fabaceae) family, and different forms such as carob extract and flour are preferred by parents because it is a natural sweetener and a source of vegetable carbohydrates. CS is rich in polyphenols and flavonoids. When we questioned histories of the cases of early puberty and puberty variants who applied to our clinic, we noticed long-term and regular use in some cases. We planned to experimen...

Background: Hypergonadotropic hypogonadism(HH) in females results from primary gonadal failure related to genetic defects affecting ovarian development and function or acquired gonadal damage; limited knowledge exist regarding underlying genes involved or potential gene X environment interactions responsible for disease trait manifestations. While pathogenic variants in single genes, chromosomal abnormalities such as Turner syndrome and acquired gonadal damage...

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...

The weight of birth affects the weight status and fat distribution in the later period of life. It is suggested that both low and high birth weight pose a risk for cardiometabolic diseases. In this study, the effects of birth weight on body fat mass and body fat distribution parameters during childhood and adolescence period were evaluated.Method: In this cross-sectional study, 4581 children ages between 6-17 years at primary and secon...

Background: No large study comparing efficiency of prednisolone, alendronate and pamidronate has been conducted so far in children with hypercalcemia due to vitamin D intoxication.Objective and hypotheses: To perform a multicentre, retrospective study assessing clinical characteristics and treatment results.Method: A standard questionnaire was uploaded to an online national database system (www.favorsci.org) to collect data of chil...

Background: Our study aimed to determine the molecular characterization of thyroid nodules and cancer in childhood and investigate the genotype-phenotype relationship.Methods: The pre-postoperative clinical follow-up features and genetic characteristics of 62 patients were evaluated. Next-generation sequencing (NGS) was used to investigate common variants in thyroid lesions with sufficient tissue in the pathology archive...

Objective: Autoimmunity of the adrenal gland, also known as Addison’s disease, is characterised by cell mediated immune destruction of the adrenal cortex. We present a child with Addison’s disease who has severe hyponatraemia and normokalemia, which led to an inappropriately low index of suspicion initially at presentation.Case: A 12-year-old boy diagnosed with adrenal deficiency was admitted to hospital with 2 weeks of vomiting, fatigue and we...
