Background: Recurrence of craniopharyngiomas influences mortality. Apart from the extent of surgical resection, few clinical parameters have been consistently shown to be associated with recurrence. Radical resection is difficult due to infiltration of surrounding tissue and unacceptable morbidity. Predictors of recurrence are therefore needed.Aim: To establish a multinational cohort of patients with craniopharyngioma an...

Background: Being born small for gestational age (SGA) is linked with higher systolic blood pressure (SBP). Fetuses with growth restriction (FGR) may be either SGA or appropriate size for gestational age at birth. However, it is not known which factors contributing to size at birth influence the relationship with SBP.Aim: To determine whether antenatal markers of FGR can predict the upper quartile of childhood SBP.<p...

Introduction: Delayed puberty (DP), affecting over 2% of adolescents, is defined as pubertal onset 2-2.5 SDs later than the general population. The most common underlying aetiology is self-limited DP (SLDP). However, this can be difficult to differentiate from the more severe condition congenital hypogonadotrophic hypogonadism (HH), especially on first presentation of an adolescent patient with DP. This study sought to elucidate phenotypic and genotypic discre...

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Background: Biallelic QRSL1 mutations cause mitochondrial “combined oxidative phosphorylation deficiency-40” (COXPD40). COXPD40 has been reported invariably lethal in infancy. Adrenal insufficiency was weakly reported and investigated among seven previously reported patients with COXPD40.Objective: We report clinical, biochemical, molecular, and functional characteristics of a patient with adrenal in...

Aim: In this study, we investigated whether there was a relationship between prolactin hormone (PRL), whose excess levels lead to infertility, and expression of Kisspeptin (Kiss1), Neurokinin (Tac2) and their respective Receptors.Material and Methods: In our study, 12-16 weeks old 40 female Wistar Albino rats were classified into three groups; control group (n=10), physiological saline (SF) (n=1...

Background: The variable presence of adrenal insufficiency (AI) due to hypocortisolemia (HC) in patients with thalassemia is well established; however, the prevalence of adrenocortical hypofunction (ACH) in the zona glomerulosa and zona reticularis of the adrenal cortex is unknown.Objective and hypotheses: To establish the prevalence of ACH, we examined the cortisol response to 1 μg- and 250 μg- ACTH tests, plasma aldosterone (A)/plasma renin a...

Type 1 Diabetes (T1DM) is a chronic metabolic disease characterized by hyperglycemia due to absolute insulin deficiency as a result of autoimmune damage of pancreatic β cells. In its treatment, insulin, medical nutrition therapy and exercise is recommended. Although it is known that exercise contributes to disease control, the mechanism of these effects has not been fully clarified. It is thought that myokines such as irisin and sestrin, can be effective by secreting with...

Background and aims: The interpretation of serum 17α-hydroxyprogesterone (17OHP) results is difficult as age-related pediatric reference intervals are scant. The aim of this study is to determine the reference intervals for serum 17OHP according to sex and age groups in newborns. We also aimed to establish reference intervals for right and left adrenal gland sizes, and to evaluate the relation with adrenal size and serum 17OHP concentrations in newborns.<p class="abst...

Background and aim: C-peptide is an important indicator of endogenous insulin release. Our aim was to investigate the association of serum C-peptide levels with age, BMI and insulin doses in newly diagnosed type 1 diabetic (DM1) children.Metods: The patients with newly diagnosed DM1 were enrolled the study and classified as DM1A and DM1B. Clinical and laboratory findings of all the patients were recorded. Daily insulin doses, BMI and its z score were cal...
