Introduction: Noonan Syndrome (NS) is a heterogeneous group of diseases with a genetic etiology affecting the RAS/MAPK signaling pathway known as RASopathy. Genes known to cause NS are PTPN11, KRAS, SOS1, RAF1, BRAF, SHOC2 and RIT1. There are sufficient studies indicating that recombinant growth hormone (rhGH) therapy can be given without increasing risk of developing cancer in NS cases with PTPN11 mutations from different centers. In this study, it was aimed ...

Keywords: Hashimoto’s thyroiditis, autoimmune thyroiditis, hypothyroidismObjective: In our study, it was aimed to determine the clinical course of the disease by evaluating the cases diagnosed with Hashimoto's thyroiditis (HT) periodically, clinically, laboratory, and radiologically.Material and Method: Patients diagnosed with HT without chronic systemic disease, drug us...

Calcineurin inhibitors (CNIs) are widely used in pediatric transplantation for prevention of graft rejection, prophylaxis and treatment of graft versus host disease. Though hyperkalemia is a common adverse effect (10-45%), alterations in renin-angiotensin-aldosterone system in CNI-induced hyperkalemia are not well elucidated. Consequently, CNIs vital to transplantation are usually switched. Here, we describe two cases with CNI-induced hyperkalemia due to hyporeninemic hypoaldo...

Introduction: The annual incidence of Langerhans cell histiocytosis (LCH) is 5 per million in admission with a diagnosis of isolated central diabetes insipidus (CDI) in children under the age of 15. Here, the process leading to the diagnosis of LCH at presentation with isolated CDI, imaging findings, and the sellar erosion, which has not been previously reported in the literature, will be discussed.Case presentation: A 4-year-5-month-old...

Introduction: IMAGE Syndrome (#614732) is an autosomal dominant inherited syndrome as a result of CDKN1C mutation characterized by the association of intrauterine growth retardation, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies. Here, long-term follow-up of a case with clinical IMAGE syndrome, no genetic mutation was detected, will be presented.Case: A three-month-old baby boy was brought wi...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is an inherited peroxisomal disease characterized by beta oxidation disorder that causes the accumulation of very long chain fatty acids (VLCFA) in all tissues. It presents with clinical signs due to accumulation of VLCFA in brain white matter, testes, adrenal cortex and skin fibroblasts. Here, we will present a case applied to the outpatient clinic due to not going through puberty period and who was diagnose...

Introduction: Neonatal severe hyperparathyroidism (NSHPT) is a life-threatening disease characterized by hypercalcemia and bone demineralization due to homozygous or compound heterozygous loss-of-function mutations in the calcium-sensing receptor (CaSR) gene. Most cases require emergency parathyroidectomy to be life-saving. Alternative treatments, such as pamidronate and cinacalcet, may be used until surgery is feasible. We present a case of severe hypercalcem...

Introduction: The SHOX (short stature homeobox) gene, located in the pseudoautosomal region of the X and Y chromosomes, implicated in Leri-Weill dyschondrosteosis, Langer mesomelic dysplasia, idiopathic short stature. Growth hormone (GH) therapy has proven effective in promoting height gain in patients with SHOX deficiency. We will present a case who was treated for borderline precocious puberty and diagnosed with Leri-Weill dyschondrosteosis upon adm...

Introduction: Derivative chromosome is a rearrangement involving two or more chromosomes or the presence of multiple abnormalities in a single chromosome and always contains intact centromere. Segmental anomalies such as inversion or translocation in derivative chromosome may result in partial duplication or deletion during meiosis. Chromosomal translocations usually result in miscarriage and multiple anomalies (common neurodevelopmental defects, growth retard...

DNA ligase IV (Lig 4) deficiency (MIM #606593) is a rare autosomal recessive disorder related with impaired DNA damage-response mechanisms. Lig 4 syndrome has a broad clinical presentation; microcephaly, facial abnormality, sensitivity to ionizing radiation, combined immunodeficiency, progressive bone marrow failure and predisposition to malignancy. We describe the patient with Lig4 syndrome presented lissencephaly, growth failure and hypogonadism. The patient is a 18-years-ol...
