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...

Background: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires accurate diagnosis and urgent treatment. Congenital adrenal hyperplasia is the most common cause of PAI in children. Non-CAH causes of PAI are relatively rare. Although several molecular causes have been found, it is emerging that considerable overlap in the clinical and biochemical features of these conditions exists.Objective and hypotheses: We inv...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

Aims: Historical I-CAH data shows considerable variation in the management of 21-hydroxylase deficiency (21-OHD) congenital adrenal hyperplasia (CAH) in infancy despite existence of several guidelines. Using the I-CAH registry we analysed contemporary early infancy natural history data, creating benchmarks as part of continuous quality improvement.Methods: Of 136 infants born in 2018-2023 and treated for 21-OHD CAH withi...

Background: In 2019, the International CAH Registry (I-CAH) performed a benchmarking exercise of acute adrenal insufficiency related adverse events including adrenal crises (AC) and sick day episodes (SDE).Methods: In 2022, I-CAH data on children aged <18 years at first visit with 21-hydroxylase deficiency CAH from 35 centres in 19 countries were analysed to examine the current occurrence of SDE and AC and compare it ...

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...

Hypophosphatasia is characterized by defective mineralization of bone and/or teeth in the presence of low activity of serum and bone alkaline phosphatase. Clinical features range from stillbirth without mineralized bone at the severe end to pathologic fractures of the lower extremities in later adulthood at the mild end. Although the disease spectrum is a continuum, six clinical forms are usually recognized based on age at diagnosis and severity of features: Perinatal (severe)...

Background and hypotheses: Urinary C-peptide creatinine ratio (UCPCR) is a new, non-invasive, economical test recommended in differential diagnoses of maturity-onset diabetes of the young (MODY). There are a few studies on this topic. UCPCR values were determined as >0.2 and >0.7 nmol/mmol with a high specificity and sensitivity in differential diagnosis in the previous two studies, the values were evaluated in only three MODY types (HNF1A/HNF4A/GCK-MODY). We investiga...

Background: There is currently an inadequate number of studies on nodule and malignancy development in children and adolescents with Hashimoto thyroiditis (HT).The aim of our study was to determine the rate of thyroid nodules and the nodule malignancy rate in our pediatric HT patients.Material and methods: Patients who were diagnosed with HT between 2004 and 2013 were included in the study. The HT diagnosis was made with the elevation of anti-TPO and ant...

Introduction: Type 1 Diabetes Mellitus (T1DM) is a chronic disease in children and adolescents.There are studies showing that quality of life is affected in T1DM. In our study, we aimed to evaluate the effect of diabetes knowledge levels on quality of life and metabolic status.Methods: Patients aged >10 years who were diagnosed with diabetes mellitus in our clinic and who were given diabetes education and who had reg...
