Adrenal insufficiency (AI) is defined as the inability of the adrenal cortex to produce adequate amounts of glucocorticoids and/or mineralocorticoids. As these hormones have important roles in water-salt balance and energy homeostasis, AI is a serious and potentially life-threatening condition. Glucocorticoid replacement therapy is vital in all cases of AI.

Primary adrenal insufficiency (PAI) is a critical condition that requires prompt diagnosis and initiation of treatment. Diagnosis can be challenging due to various underlying causes, including defects in adrenal gland development, resistance to adrenocorticotropic hormone, autoimmune causes, and metabolic problems. A specific diagnosis is essential for developing a treatment plan and identifying other possible accompanying pathologies.

Exposure of the developing brain to androgens during fetal life is known to affect sexual development, including postnatal sex and sexual orientation. However, these relationships are both multifactorial and unpredictable. It is generally assumed that congenital adrenal hyperplasia (CAH) has greater effects in women than in men due to non-physiological adrenal androgen excess.

Although the most common cause of congenital adrenal hyperplasia (CAH) worldwide is 21-hydroxylase deficiency (21-OHD), which accounts for more than 95% of cases, other rare causes of CAH such as 11-beta-hydroxylase deficiency (11β-OHD), 3-beta-hydroxy steroid dehydrogenase (3β-HSD) deficiency, 17-hydroxylase deficiency and lipoid CAH (LCAH) may also be encountered in clinical practice. 11β-OHD is the most common type of CAH after 21-OHD, and CYP11B1 deficiency in adrenal steroidogenesis causes the inability to produce cortisol and aldosterone and the excessive production of adrenal androgens. Although the clinical and laboratory features are similar to 21-OHD, findings of mineralocorticoid deficiency are not observed.

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease caused by the deficiency of one of the enzymes involved in cortisol synthesis. More than 95% of the cases occur as a result of defects in the gene encoding 21-hydroxylase (). 21-hydroxylase deficiency has been divided into classical and non-classical forms.

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease caused by the deficiency of one of the enzymes involved in cortisol synthesis. Between 90% and 99% of cases of CAH are caused by 21-hydroxylase deficiency (21-OHD) caused by mutations in . Although 21-OHD has been historically divided into classical and non-classical forms, it is now thought to show a continuous phenotype.

Objective: Type 1 diabetes mellitus (T1D) is a chronic disease that is common in childhood and adolescence, where care and metabolic control are difficult for both adolescents and their parents. Parental participation in the care and treatment process, especially during adolescence when adolescents develop autonomy and take responsibility for self-care, affects both the adolescent's perception of autonomy and may cause difficulties in self-management. This study was conducted to determine the effect of parental support on adolescents' self-efficacy, quality of life (QoL) and glycaemic control in adolescents with T1D.

Objective: Osteogenesis imperfecta (OI) consists of a group of phenotypically and genetically heterogeneous connective tissue disorders that share similar skeletal anomalies causing bone fragility and deformation. The aim was to investigate the molecular genetic etiology and determine the relationship between genotype and phenotype in OI patients using targeted next-generation sequencing (NGS).
Methods: A targeted NGS analysis panel (Illumina TruSight One) containing genes involved in collagen/bone synthesis was performed on the Illumina Nextseq550 platform in patients with a confirmed diagnosis of OI.

Objective: Central precocious puberty (CPP) is treated with long-acting gonadotropin releasing hormone (GnRH) analogues (GnRHa). Some adult patients undergoing GnRHa treatment experienced prolonged QT syndrome, which is associated with an increased risk of serious cardiac events, such as myocardial infarction, stroke, arrhythmias, and sudden cardiac death.
Methods: Seventy-four patients, aged between 5 and 11 years and diagnosed with CPP but with no other concomitant disease or medication use, underwent electrocardiogram (ECG) assessment.

Objective: Maturity onset diabetes of the young (MODY) occurs due to mutations in genes involved in pancreatic beta cell function and insulin secretion, has heterogeneous clinical and laboratory features, and account for 1-5% of all diabetes cases. The prevalence and distribution of MODY subtypes vary between countries. The aim of this study was to evaluate the clinical and laboratory characteristics, mutation distribution, and phenotype-genotype relationship in a large case series of pediatric Turkish patients genetically diagnosed with MODY.

Objective: Craniopharyngiomas (CPG) have complex treatment challenges due to their proximity to vital structures, surgical and radiotherapeutic complexities, and the tendency for recurrence. The aim of this study was to identify the prevalence of endocrine and metabolic comorbidities observed during initial diagnosis and long-term follow-up in a nationwide cohort of pediatric CPG patients. A further aim was to highlight the difficulties associated with CPG management.

In terms of prevalence, 11β-hydroxylase deficiency (11β-OHD), a common form of congenital adrenal hyperplasia, closely follows 21-hydroxylase deficiency. 11β-OHD has been attributed to diminished enzymatic activity owing to gene variants, mainly encompassing single nucleotide variations and insertions-deletions. The involvement of chimeric genes in 11β-OHD has rarely been reported.
