Introduction: Vitamin D-dependent rickets (VDDR) describes a group of genetic disorders characterized by early-onset rickets that develops due to insufficient concentration of active forms of vitamin-D or unresponsiveness to active vitamin D. The aim of this study was to share the clinical features and long-term outcome of cases followed up in our center with the diagnosis of either VDDR-Type-1 and VDDR-Type-2.Method: Pr...

Introduction: Barakat syndrome, also known as HDR syndrome (OMIM 146255), is a clinically heterogeneous, rare, autosomal dominant genetic disorder, characterized by the triad of hypoparathyroidism (H), deafness (D), and renal disease (R). The phenotypic features are attributed to mutations of the GATA3 gene, which encodes a transcription factor essential for embryonic development of the parathyroid glands, auditory system, and kidneys. Here, we report...

Introduction: Aggrecan is a major proteoglycan component of the articular and growth plate extracellular matrix, encoded by the ACAN gene (MIM: 155760). Although short stature and various dysmorphic findings are observed in individuals with ACAN mutations, the relationship between genotype and phenotype is not clear.Case: A 6.75-year-old pre-pubertal girl presented with disproportionate short stature. She was full term f...

Introduction: It is thought that long-term growth hormone (GH) treatment may impair hepatic glucose production and insulin-dependent glucose utilization, and therefore it is attributed that GH may adversely affect glucose metabolism.Objective: In our study, we aimed to examine the effects of GH treatment on insulin sensitivity and glucose metabolism in patients with GH deficiency after 1-year of treatment.<p class="a...

Introduction: The frequency of solid and hematological malignancies has been reported to be higher in children with Turner syndrome than in the general population. Mycosis fungoides (MF) represent the most common type of cutaneous T-cell lymphoma, which is a low-grade lymphoproliferative disease. To the best of our knowledge, the coexistence of Turner syndrome and MF has not yet been reported. Here, we report a girl with Turner syndrome and MF.<p class="ab...

Introduction: Luscan-Lumish syndrome (LLS) is a postnatal overgrowth syndrome characterized by macrocephaly, mental retardation, seizures, postnatal overgrowth, and developmental delay, caused by a heterozygous mutation in the SETD2 gene on chromosome 3p21, which exhibits autosomal dominant inheritance.Case Report: A ten-year-old girl presented with menarche. She was born to healthy non-consanguineous parents at 37 weeks...

Purpose: We aimed to determine the frequency and distribution of intracranial pathologies in patients over 8 years of age by evaluating MRI images of patients diagnosed with early puberty-rapidly progressive.Materials and Methods: The study comprised 118 female patients diagnosed with precocious puberty (PP) and rapidly progressive early puberty (RPEP). The onset of puberty in girls before the age of 8 years is defined a...

Introduct&idot;on: Thyroid cancers are rare malignancies in childhood and their incidence is between 1.5-3% among all childhood cancers. Papillary thyroid cancer (PTC) constitutes more than 90% of childhood thyroid cancers. Risk factors for thyroid cancer include; There are iodine deficiency, radiation exposure, radiotherapy to the head and neck region, and genetic predisposition. We will present an 8-year-old case who presented with a complaint of neck swelli...

Introduction: The incidence of Cushing disease (CD) is 0.7-2.4/year per million, andadolescents and children make up 10% of new cases annually. However, thesensitivity and specificity of tests used to diagnose CD in childhood may bepoor, resulting in difficulties in diagnosis and treatment. The aim was to reportpediatric CD patients attending our pituitary referral center for surgery and todescribe their diagnosis, treatment and long-term follow-up.<p clas...

Introduction: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy(APECED) is a rare autoimmune disease caused by a loss-of-function mutation in the autoimmune regulator gene(AIRE). AIRE gene mutation disrupts the negative selection of self-reactive T cells in the thymus, causing autoimmune reactions in endocrine and non-endocrine tissues. Impairment in T cell function is also associated with susceptibility to specific infections along with autoimmun...
