Hypomyelination and congenital cataract (HCC) is a condition, which is caused by mutations in the gene and is characterized by congenital cataract, progressive neurologic impairment, and myelin deficiency in both the central and peripheral nervous system. We present the findings of three siblings who applied to us with the same clinical features. These patients were referred to our clinic due to the presence of bilateral congenital cataract and progressive neurological impairment with peripheral neuropathy.

Background: Our aim in this study was to evaluate the efficacy of magnetic resonance imaging (MRI) studies in the detection of brain regions effected by Sydenham chorea and to determine whether they provided data regarding the pathogenesis of Sydenham chorea. To this end, we assessed basal ganglia structures in Sydenham chorea patients and control group by quantitative MRI volumetric analysis.

Methods: Patients with a recent onset of chorea and control subjects matched for age and gender were included in the study.

Objective: The objective of the study was to identify the relationship between subcortical gray matter (GM) volumes and juvenile myoclonic epilepsy (JME).

Methods: We analyzed the brain magnetic resonance imaging (MRI) scans that were performed during the time of the diagnosis of epilepsy by using voxel-based morphometry (VBM) method. The volumetric three-dimensional sequence was used for structural investigation.

The aim of this study is to evaluate the abnormal cortical structures associated with newly diagnosed benign epilepsy with centrotemporal spikes (BECTS) patients and assessed the effects of comorbid attention-deficit/hyperactivity (ADHD) on these abnormalities. Newly diagnosed BECTS patients (n = 33, 23 males) and age-matched healthy controls (n = 48) were evaluated by surface and volumetric MRI. CAT12 toolbox (HYPERLINK "http://www.

Objective: The objectives of this study were to evaluate the demographic and clinical characteristics, causes, treatment patterns, outcome, and recurrence of childhood peripheral facial palsy.

Methods: We performed a retrospective study of 144 peripheral facial palsy patients, under 18 years old in a tertiary care pediatric hospital. Medical charts were reviewed to analyze the age, gender, side of facial nerve paralysis, family history, cause, grading by the House-Brackmann Facial Nerve Grading Scale (HBS), results of diagnostic tests, therapies, outcomes, and recurrence.

Objective: Sydenham's chorea is the most common cause of acquired chorea in children and is the major manifestation for acute rheumatic fever. Despite being known as a benign, self-limiting condition, recurrences and persistence of symptoms can be seen. In this study, we aimed to evaluate retrospectively the clinical and laboratory features of patients with Sydenham's chorea and the rate and the course of recurrences, and to assess the risk of recurrences.
