Analisamos as manifestações clínicas de 27 crises parciais complexas do lobo temporal registradas em vídeo-EEG com ênfase nas manifestações motoras, principalmente postura distônica, paresia crítica e versão forçada dos olhos e cabeça. A origem das crises no lobo temporal foi baseada na concordância dos exames pré cirúrgicos, que incluiam vários EEGs intercríticos e críticos, alterações na TC e RM do crânio, SPECT intercríticos e, em alguns pacientes, também críticos. 8 pacientes tiveram ressecções temporais; em 7 foi feita lobectomia temporal sendo demonstrada esclerose mesial temporal em 5; 1 paciente foi submetido a amígdalo-hipocampectomia seletiva e o achado anátomo-patológico consistiu de hemossiderose e gliose hipocampal, possivelmente decorrentes de sangramento de um aneurisma gigante da artéria cerebral posterior. Todos os pacientes estão sem crises após a cirurgia. Enquanto postura distônica e paresia crítica, presentes em 18(66.6%) das crises, foram sempre contralaterals à área epileptogênica e assim, de valor indiscutível para lateralização, versão de olhos e cabeça ocorreu tanto ipso como contralateralmente

Search for supersymmetry in pp collisions at in events with a single lepton, large jet multiplicity, and multiple b jets

Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are identified as b jets. The data sample corresponds to an integrated luminosity of 19.3 fb(-1) recorded by the CMS experiment at the LHC in 2012. The search is motivated by supersymmetric models that involve strong-production processes and cascade decays of new particles. The resulting final states contain multiple jets as well as missing transverse momentum from weakly interacting particles. The event yields, observed across several kinematic regions, are consistent with the expectations from standard model processes. The results are interpreted in the context of simplified supersymmetric scenarios with pair production of gluinos, where each gluino decays to a top quark-antiquark pair and the lightest neutralino. For the case of decays via virtual top squarks, gluinos with a mass smaller than 1.26 TeV are excluded for low neutralino masses

Searches for supersymmetry based on events with b jets and four W bosons in pp collisions at 8 TeV

Five mutually exclusive searches for supersymmetry are presented based on events in which b jets and four W bosons are produced in proton-proton collisions at root s = 8TeV. The data, corresponding to an integrated luminosity of 19.5 fb(-1), were collected with the CMS experiment at the CERN LHC in 2012. The five studies differ in the leptonic signature from the W boson decays, and correspond to all-hadronic, single-lepton, opposite-sign dilepton, same-sign dilepton, and >= 3 lepton final states. The results of the five studies are combined to yield 95% confidence level limits for the gluino and bottom-squark masses in the context of gluino and bottom-squark pair production, respectively. In the limit when the lightest supersymmetric particle is light, gluino and bottom squark masses are excluded below 1280 and 570 GeV, respectively
