Identification of Gene Mutations/Deletions in Patients with Early Onset Epilepsy.

Background And Aims: gene, which encodes protocadherin 19, is associated with epilepsy and intellectual disability, mainly in affected females. The clinical manifestations are heterogeneous and the main features include early onset seizure, generalized or focal seizures sensitive to fever, and brief seizures occurring in clusters. The disorders exhibit a unique and unusual X-linked pattern of expression.

Cerebellar volume in early-onset schizophrenia and its association with severity of symptoms.

Objectives: This study aimed to investigate whether early-onset schizophrenia (EOS) cases differ from controls regarding volumes of the total cerebellum and the right and left cerebellar hemispheres, and volumetric asymmetry. Correlations of cerebellar volumes and asymmetry indices with severity of symptoms and general functioning in cases of EOS were also assessed.

Methods: Adolescents with EOS (n = 23) were compared with controls (n = 23).

Importance of neurologic and cutaneous signs in the diagnosis of Schimke immuno-osseous dysplasia.

Schimke immuno-osseous dysplasia is an autosomal recessive multisystem disorder caused by defects in SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a-like 1 gene (SMARCAL1). SMARCAL1 product is a helicase that has role in selective cellular proliferation. The disorder is characterized by spondyloepiphyseal dysplasia with short stature, nephropathy, T cell deficiency, neurologic and cutaneous signs.

Importance of acrocyanosis in delayed walking.

We present a four-year-old wth ethylmalonic encephalopathy who presented with delayed walking. She had bilateral hyperintense lesions in the basal ganglia. Molecular analysis revealed a homozygous c.

Measurement of the apparent diffusion coefficient in paediatric mitochondrial encephalopathy cases and a comparison of parenchymal changes associated with the disease using follow-up diffusion coefficient measurements.

Objectives: To reveal the contribution of MRI and diffusion-weighted imaging (DWI) to the diagnosis of mitochondrial encephalopathy (ME) and to evaluate the parenchymal changes associated with this disease in the involved parenchymal areas using the apparent diffusion coefficient (ADC) parameter.

Methods: Ten patients who had undergone MRI and DWI analysis with a pre-diagnosis of neurometabolic disease, and who were subsequently diagnosed with ME in laboratory and/or genetic studies, were included in our study. ADC values were compared with a control group composed of 20 patients of similar age with normal brains.

A case of rapid-onset obesity with hypothalamic dysfunction, hypoventilation, autonomic dysregulation, and neural crest tumor: ROHHADNET syndrome.

Objective: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) is a rare disorder that mimics both common obesity and genetic obesity syndromes along with several endocrine disorders during early childhood. We aim to present the clinical features, laboratory and imaging results, and treatment outcomes of a patient with ROHHAD syndrome.

Methods: In this case report, we describe a 26-month-old boy who was admitted to our emergency department with dyspnea and cyanosis and was suspected to have ROHHAD syndrome due to his rapid-onset obesity and alveolar hypoventilation.
