Is There a Relation Between Vitamin B-12 Levels and Headaches in Children and Adolescents?

Objective: Primary headaches are common and benign discomforts both in children and adolescents. However, they have a negative influence on the quality of life. This retrospective study aimed to determine the relationship between vitamin B-12 results and primary headaches in Turkish children

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.3G>T mutation in the ETHE1 gene. She did not have typical findings of the disease including recurrent petechia, chronic diarrhea and acrocyanosis was very subtle and orthostatic. She benefited from riboflavine and Q10 treatments. We suggest that acrocyanosis should be questioned and examined in patients with motor delay

Expanding spectrum of SCN1A-related phenotype with novel mutations

Mutations in the genes encoding voltage-gated sodium channels cause a variety of epilepsy syndromes, with most of the mutations occurring in SCN1A gene. It is one of the most well-researched epilepsy genes. The SCN1A gene, which seems to be a relevant regulator of excitability of the CNS, is implicated in various epilepsy phenotypes through various genetic mechanisms ranging from common variants to rare monogenic variants. It is known that SCN1A gene is tightly linked to severe myoclonic epilepsy of infancy (SMEI). However, its phenotypic spectrum is expanding. Here, we report clinical and genetic findings of 10 patients with SCN1A mutations where two of them were found to have novel mutations. Our findings support understanding and updating knowledge on the correlation between phenotype distribution and location and type of mutations in SCN1A-related disorders

Clinical predictors of drug-resistant epilepsy in children

Background/aim: In up to 20% of epilepsy patients, seizures may not be controlled despite the use of antiepileptic drugs, either alone or in combination. These individuals are considered to have drug-resistant epilepsy. Drug-resistant epilepsy is usually associated with intellectual disability, psychiatric comorbidity, physical injury, sudden unexpected death, and low quality of life. Early detection and prediction of drug-resistant epilepsy are essential in determining the patient's most appropriate treatment option. This retrospective study aimed to determine the clinical, electroencephalographic, and radiological factors associated with medically intractable childhood seizures. Materials and methods: Data regarding 177 patients diagnosed with drug-resistant epilepsy were compared with 281 patients with drug-responsive epilepsy. Results: Univariate analysis showed that age at seizure onset, having mixed seizure types, history of status epilepticus, history of neonatal seizures, history of both having febrile and afebrile seizures, daily seizures at the onset, abnormality on the first electroencephalogram, generalized epileptic abnormality on electroencephalogram, abnormal neurodevelopmental status, abnormal neuroimaging, and having symptomatic etiology were significant risk factors for the development of drug-resistant epilepsy (p < 0.05). In multivariable analysis, having mixed seizure types, history of status epilepticus, having multiple seizures in a day, intellectual disability, symptomatic etiology, and neuroimaging abnormality remained significant predictors for developing drug-resistant epilepsy. Conclusions: In the course of childhood epilepsy, some clinical features may predict the outcome. Early identification of patients with high risk for drug-resistant epilepsy will help plan the appropriate treatment option. Further prospective studies should confirm these findings

Intravenous levetiracetam for treatment of seizures in term and preterm neonates

Context: Seizures are the most frequent neurological disturbance in the neonatal period, and there are no evidence-based guidelines for the treatment of neonatal seizures. Here we report a study on the use of levetiracetam as second-line therapy in the treatment of seizures in term and preterm neonates. Aim: The aim of this study was to assess the efficacy and safety of levetiracetam for seizures of term and preterm neonates. Settings and Design: We retrospectively analyzed data of the patients who had seizures and who were treated with levetiracetam as an add-on therapy to phenobarbital during the neonatal period. Statistical Analysis: The Statistical Package for the Social Sciences (SPSS) software, version 15.0 (SPSS, Chicago, Illinois), was used for statistical analysis. Continuous variables were expressed as mean values and standard deviations. Results: Thirty-six patients (8 term and 28 preterm) received levetiracetam. Mean dose of levetiracetam was 31.67 +/- 14.83mg/kg/day. Twenty-five of the patients (69.4%) were seizure free with levetiracetam treatment. Electroencephalography recordings improved in 28 (77.8%) of the patients after levetiracetam. No severe adverse effects were observed. Conclusion: Our data suggest that levetiracetam may be a safe and effective treatment for neonatal seizures, which are unresponsive to phenobarbital

Myelin Oligodendrocyte Glycoprotein Antibody Persistency in a Steroid-Dependent ADEM Case

Myelin oligodendrocyte glycoprotein (MOG) is a candidate target antigen in demyelinating central nervous system diseases, including acute disseminated encephalomyelitis (ADEM), neuromyelitis optica, and multiple sclerosis. It may give prognostic information regarding monophasic or recurrent course of the disease. MOG antibodies have been shown to be positive in high titers during the first episode of ADEM with rapidly decreasing to undetectable limits after recovery. However, persistent MOG antibodies are considered as a predicting factor for multiple sclerosis, optic neuritis relapses, and incomplete recovery of ADEM. Here we report a unique case with persistent MOG antibodies presented with multiphasic ADEM-like attacks. A 6-year-old girl was consulted with encephalopathy, gait disturbance, and oculomotor nerve palsy. Periventricular white matter lesions were seen on cranial magnetic resonance imaging studies. ADEM was diagnosed and treated with steroid. During follow-up, she experienced repeated episodes after steroid therapy termination. We were able to search MOG antibody at the ninth attack. The positivity of this antibody remained. It was thought to be associated with steroid-dependent course, and azathioprine and intravenous human immunoglobulin treatment were added. Patients with persistent MOG antibodies may benefit from addition of immunosuppressant agents, which may decrease the number of attacks
