Puberty is a physical, hormonal and psychosocial transition from childhood to adolescence. Precocious puberty (PP) is the beginning of secondary sexual characteristics before eight years of age in girls. The most common type is known as “central precocious puberty (CPP)”. CPP occurs due to early activation of the hypothalamus-pituitary-gonad (HPG) axis. Although the real trigger for idiopathic CPP is unknown, it has been proposed that it may be caused by the interact...

Introduction: The etiology of hyperandrogenism is diverse and diagnosis is based on history, clinical findings, reliable measurement of steroid hormones and genetic analyzes. In the electrochemiluminescence immunoassay (ECLIA) method, the presence of various endogenous compounds and the use of certain pharmaceutical agents may cause interference in results, on the other hand liquid chromatography-mass spectrometry (LC-MS/MS) method allows measurement of 17 adr...

Introduction: Anti-thyroid arthritis syndrome (AAS) is a rare complication that may occur in patients treated with anti-thyroid drugs. Presentation is variable and may include myalgia, arthralgia, skin rash, high fever, and polyarthritis. Herein, we present a girl diagnosed with AAS. Case report: A 9-year-old girl was admitted to emergency complaining of fever and arthralgia. She was the second child of non-consanguineous healthy parents. She had been d...

Background: Osteogenesis imperfecta (OI) is a genetic disorder characterized by diffuse osteoporosis, recurrent fractures, and resulting deformities. Bruck syndrome (BS) is a rare autosomal recessive disease that manifests with many symptoms of OI. In addition to the deficiency of type I collagen in OI, congenital joint contractures also occur in BS. BS is caused by mutations of FKBP10 (BS type 1) and PLOD2 (BS type 2) genes encoding the chaperone-collagen com...

Introduction: SHOX deficiency is the most common cause of monogenic short stature and results in short stature with a highly variable phenotype. In this study, we aimed to detect SHOX gene pathologies in patients who applied to the pediatric endocrine outpatient clinic with short stature and who were found to have Madelung deformity on hand-wrist radiography, and to evaluate the clinical, laboratory features and responses to growth hormone (GH) treatment.<...

Introduction: Mutations of the PLS3 gene (MIM 300910), encoding plastin 3, are an extremely rare cause of osteogenesis imperfecta (OI). It has an X-linked inheritance and is characterized by early-onset osteoporosis and kyphosis, which can cause compression fractures, especially in the thoracic vertebrae. Although there are reports showing that bisphosphonates are effective in improving the bone mineral density of patients with PLS3 variants,...

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...
