Background: Febrile seizure is the most common childhood neurological disorder, is an important health problem with potential short-and long-term complications, also leading to economic burden and increased parental anxiety about fevers and seizures occurring in their children. There are no routine recommendation to detect etiological causes of FS for neurological perspective, further knowledge about the etiological causes of FS in children will support preventive measures and follow-up strategies. The aim of this study is to evaluate the percentage of respiratory viruses in children with FS. Methods: This prospective multicenter study, entitled "Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)" examined representative populations in eight different cities in Turkey between March 1, 2016 and April 1, 2017. Nasopharyngeal swabs were taken from all children at presentation. A respiratory multiplex array was performed to detect for influenza A and B; respiratory syncytial virus A and B; human parainfluenza virus 1-2-3 and 4; human coronavirus 229E and OC43; human rhinovirus; human enterovirus; human adenovirus; human bocavirus; human metapneumovirus. Results: During the study period, at least one virus was detected in 82.7% (144/174) of children with FS. The most frequently detected virus was adenovirus, followed by influenza A and influenza B. Detection of more than one virus was present in 58.3% of the children with FS, and the most common co-existence was the presence of adenovirus and influenza B. In children younger than 12 months, Coronavirus OC43 was the most common, while influenza A was most frequently observed in children older than 48 months (p < 0.05). Human bocavirus was common in children who experienced complex FS, while respiratory syncytial virus (RSV) A was more common in children who experienced simple FS. Influenza B virus was the most common virus identified in children who were experiencing their first incidence of FS (p < 0.05).Conclusions: This study indicates that respiratory viruses are important in the etiology of FS in children. The results show that antibiotics must be prescribed carefully in children with FS since the majority of cases are related to viral causes. Widespread use of the existing quadrivalent influenza vaccine might be useful for the prevention of FS related to the flu. Further vaccine candidates for potential respiratory pathogens, including RSV, might be helpful for the prevention of FS. ARTICLE HISTORY

Aim:The aim of this study was to retrospectively evaluate clinical features, treatment and prognosis of 20 patients followed up as Lennox-Gastaut Syndrome in ESOGU in the Division of Pediatric Neurology. Material and Method: Multiple different types of seizure, diffuse spike-wave pattern(<3 Hz) on electroencephalogram, psychomotor retardation were the diagnostic criteria for Lennox-Gastaut Syndrome. The patients who had no etiologic reason were described as the idiopathic type. Prenatal, natal and postnatal risk factors, seizure and clinical features, neurodevelopmental status, treatment and prognostic features were evaluated. Results: Thirteen patients were female, seven were male; male/female ratio was 1,9. Nineteen patients were described as the symptomatic type. Hypoxic ischemic encephalopthy was the most common risk factor. Sixty percent of the patients had a history of infantile spasms. Generalized tonic, generalized tonic clonic and atonic drop attacks were the most common seizure types. Speech impairment and microcephaly were the most frequently seen neurologic findings. Diffuse spike-wave activity (1-3 Hz/s) on EEG, bioelectrical status epilepticus and 9-14 Hz/s fast activity discharges were the most commonly seen discharges. The most common neuroimaging finding was cerebral atrophy. Sixty percent of the patients suffered from a large number of seizures per day despite multiple antiepileptic drugs. The most commonly used antiepileptic drugs were valproate sodium, clobazam, lamotrigine and topiramate. Conclusions: The prognosis of Lennox-Gestaut Syndrome is poor due to either recurrent seizures or mental deterioration. Seizure control can not be provided despite the use of multiple anti-epileptic drugs. New antiepileptic drugs are needed. (Turk Arch Ped 2012; 47: 49-54)

Although the calculated prevalence rate was compatible with previous studies, positive family history for BHS, birth sequence, parents' education status and fathers' age were identified as risk factors associated with BHS.

The purpose of this study was to investigate the relationship between angiotensin-converting enzyme gene insertion/deletion (I/D) polymorphism and respiratory distress syndrome (RDS) in premature neonates. The patient group consisted of 101 premature neonates born before 37 weeks of gestation and diagnosed as RDS. The control group consisted of 100 premature neonates born before 37 weeks of gestation, but was not diagnosed as RDS. Genomic DNA from patients and controls was analyzed by polymerase chain reaction. D/D genotype was significantly higher in patient group (60.4% patients vs. 37.0% controls, p<0.05), whereas in the controls I/D genotype was markedly higher (33.7% patients vs. 61.0% controls, p<0.05). However, no marked change was observed with I/I genotype (5.9% patients vs. 2.0% controls). A significant increase of D alleles was observed in patients, whereas I allele was higher in controls (p<0.05). These results demonstrated the existence of higher frequency of the D/D genotype and D allele in premature neonates with RDS. These data may suggest that carriers of the D/D genotype and D allele are at increased risk of RDS development in premature neonates.

Cat scratch disease (CSD) is a benign, self-limiting condition associated with Bartonella henselae. Neurological manifestations are uncommon. Acute transverse myelitis and Guillain-Barré syndrome have been reported rarely with CSD. This report describes a 12-year-old boy with acute transverse myelitis and Guillain-Barré syndrome associated with CSD.
