Risk factors for a first febrile seizure: A matched case-control study

Abstract: Summary We conducted a matched casecontrol study to identify risk factors for first febrile seizures, with special emphasis on characteristics of the acute illness episode. Cases were identified through hospital emergency departments; controls were identified through outpatient clinics and emergency departments. Sixtynine children with first febrile seizures and no history of previous unprovoked seizures were matched for age (±6 months), site of routine pediatric care, and date of visit (±weeks) with 1 or 2 febrile controls who had no history of previous febrile or unprovoked seizures. Medical records for the index visit were reviewed, and parents were interviewed by telephone. Illness characteristics examined included height of temperature, type of underlying illness, contact with a physician during the illness but before the index visit, and use of acetaminophen or decongestants. Family history of febrile and of unprovoked seizures, sociodemographic characteristics, daycare use, and selected preand perinatal variables were also studied. On multivariable analysis, significant independent risk factors were height of temperature, history of febrile seizures in a firstor in a higher degree relative. Gastroenteritis as the underlying illness had a significant inverse (i.e., protective) association with febrile seizures. Maternal smoking during pregnancy was a marginally significant predictor of febrile seizures.

Search for the standard model Higgs boson in the diphoton decay channel with 4.9fb -1 of pp collision data at √s=7TeV with atlas

Abstract: A search for the standard model Higgs boson is performed in the diphoton decay channel. The data used correspond to an integrated luminosity of 4.9 fb-1 collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of √s=7 TeV. In the diphoton mass range 110–150 GeV, the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations. Taking the look-elsewhere effect into account in the range 110–150 GeV, this significance becomes 1.5 standard deviations. The standard model Higgs boson is excluded at 95% confidence level in the mass ranges of 113–115 GeV and 134.5–136 GeV.

Unprovoked seizures in children with febrile seizures : Short-term outcome

Abstract: Background: Febrile seizures affect 2 to 4% of children, and 2 to 10% develop subsequent unprovoked seizures. Secondary analyses of two large cohorts identified neurodevelopmental abnormalities, complex febrile seizures, and a family history of epilepsy as predictors of unprovoked seizures. We present an analysis of children prospectively followed from their first febrile seizure to reassess these three factors, examine factors of equivocal importance, and assess the importance of some new factors that we identified as predictors of recurrent febrile seizures. Methods: Children (N = 428) were prospectively identified for a first febrile seizure through pediatric emergency departments of four hospitals. Information was collected from medical records and interviews with parents. Children were followed for 2 years or more. Results: Unprovoked seizures occurred in 26 (6%). Neurodevelopmental abnormalities, complex febrile seizures, and a family history of epilepsy were associated with an increased risk of unprovoked seizures. Recurrent febrile seizures and brief duration of fever before the initial febrile seizure were also risk factors. A family history of febrile seizures, temperature and age at the initial febrile seizure, sex, and race were not associated with unprovoked seizures. Conclusions: We confirmed the increased risk associated with traditionally accepted predictors of epilepsy following febrile seizures. Also, the risk clearly increased with recurrent febrile seizures. In general, predictors of subsequent unprovoked seizures differ from predictors of recurrent febrile seizures. One notable exception, brief duration of fever before the initial febrile seizure, predicts both types of outcome and may be a marker for an increased susceptibility to seizures.
