Background:Electrical status epilepticus in slow wave sleep (ESES) is a rare, age-related, self-limited disorder characterized as epilepsy with different seizure types, neuropsychological impairment in the form of global or selective regression of cognitive functions, motor impairment, and typical electroencephalographic (EEG) findings of continuous epileptic activity occupying 85% of nonrapid eye movement sleep.Aims:The aim is to examine the clinical and electrophysiological findings and treatment modalities of children with ESES and to evaluate the outcome of the disorder.Materials and Methods:Fourteen patients with a diagnosis of electrical status epilepticus during slow wave sleep and followed-up at least 2 years were included.Statistical Analysis:Pearson correlation test was used in the study.Results:Among the 14 patients, eight of them had normal mental development before ESES. Twelve of the patients mentioned cognitive impairment and decline in school performance during ESES. After ESES, seven patients had mental retardation in different severity. One of these patients was diagnosed with benign partial epilepsy of childhood with centrotemporal spikes and had normal intelligence quotient level prior to ESES. The diagnosis of ESES was made after newly occurred different seizure types in four of the patients while two of the previously known epileptic patients presented with only severe psychiatric impairment. Valproic acid and carbamazepine were the mostly frequently used drugs before the onset of ESES. After at least 2 years of follow-up, seven patients were seizure free, but still taking antiepileptic treatment. Five patients were seizure free, while two of them had ongoing seizures despite antiepileptic therapy.Conclusion:ESES should be kept in mind in children with unexplained regression or stagnation of development associated with seizures or not. Sleep EEGs should be performed for timely diagnosis, proper treatment and prevention of permanent cognitive impairment.

The aim of this study is to assess the seizure and developmental outcome and to determine the prognostic factors affecting the outcome of West syndrome in an etiologically well-defined large cohort. Demographic features, treatment modalities, etiology, seizure and developmental outcome of 216 cases with West syndrome were recorded retrospectively. Ten prognostic factors possibly affecting the outcome of West syndrome including (1) gender, (2) age at the onset (3) presence of seizures prior to spasms, (4) presence of asymmetric spasm, (5) presence of abnormal neurological signs, (6) treatment lag, (7) etiology, (8) drug chosen as the initial treatment, (9) response to initial treatment regardless of the kind, (10) development of other seizure types after spasms were evaluated in terms of seizure and developmental outcome. Twelve percent of the cases were developmentally normal at the end of 2-year follow-up. Ongoing seizures requiring antiepileptic drug medication at the last follow-up were noted in 90 % of the cases. Hypoxia (29 %), metabolic disorders (11 %), infectious diseases (9 %) and cerebral developmental disorders (8 %) were the most frequent etiological factors. Five of the ten prognostic factors (presence of seizures prior to spasms, presence of abnormal neurological signs, response to initial treatment regardless of the kind, etiology and development of other seizure types after spasms) were found to be statistically significant prognostic factors predicting the outcome. In conclusion, West syndrome is still a catastrophic epileptic encephalopathy. Preventable causes still constitute a substantial portion of the etiological causes of West syndrome. Therefore, the prevention of avoidable causes is at least as important as the treatment.

The present study revealed that dysferlinopathies is not an uncommon form of muscular dystrophies in western Turkey. We have concluded that if avoidance from unnecessary therapeutic interventions is desired, we must be aware of the relative frequencies of dysferlinopathies.

Pseudotumor cerebri with or without venous sinus thrombosis is a rare clinical presentation of Behçet disease in childhood. We present here a case of childhood pseudotumor cerebri without a previous diagnosis of Behçet disease. The detailed history and physical examination of the case led to the diagnosis of neuro-Behçet disease. The investigation of predisposition to thrombosis revealed heterozygous factor V Leiden mutation along with the high lipoprotein(a) level. The symptoms resolved dramatically by treatment with the combination of immunosuppression and anticoagulation with regard to the detected factor V Leiden mutation and high lipoprotein(a) level. After a symptom-free period of 9 months, the cerebral vein thrombosis recurred. We present this case to draw attention to this rare cause of pseudotumor cerebri in childhood and to emphasize the importance of additional thrombotic risk factors regarding the potential recurrence of thrombotic events in Behçet disease.
