Endoscopic Sinus Surgery Associated with Rhinoseptoplasty: A Case-control Study

Objective:. To examine the difference between outcomes in the administration of concurrent endoscopic sinus surgery (ESS), septoplasty (SP), and rhinoplasty (RP) and concurrent ESS and SP in 1 single surgical session. Methods:. Patients who underwent concurrent ESS and SP from September 2004 to July 2015 were identified. Furthermore, patients among them who underwent functional primary RP were selected. Subjects who had been administered concurrent ESS, SP, and RP (primary RP) were matched for sex, age, sinonasal surgical procedures for treatment of chronic rhinosinusitis with patients underwent concurrent ESS and SP, used as control subjects. A literature review was performed to find previous articles describing results of concurrent procedures among ESS, SP, and RP. Results:. Twenty subjects, who underwent concurrent ESS, SP, and RP, were compared with a matched control group made of 20 patients who underwent concurrent ESS and SP, evaluating different postoperative outcomes (postoperative complications, postoperative improvement of respiratory symptoms, persistence of chronic rhinosinusitis symptoms 6 months to 1 year postoperative, need of revision surgery, satisfaction of the patient). Obtained P values showed that there was no statistically significant difference (P > 0.05) as regards the different outcomes, except for postoperative complications, increased because of the invasiveness proper of RP (P < 0.05). Conclusions:. Therefore, execution of concurrent ESS, SP, and RP seems to be safe and effective, and additional RP does not modify postoperative outcomes of concurrent ESS and SP except for a little increase of postoperative complications, even if most of them had low impact on result of procedures

Measurement of the Drell-Yan Cross Section in pp Collisions at s\sqrt{s} = 7 TeV

The Drell-Yan differential cross section is measured in pp collisions at sqrt(s) = 7 TeV, from a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns. The cross section measurement, normalized to the measured cross section in the Z region, is reported for both the dimuon and dielectron channels in the dilepton invariant mass range 15-600 GeV. The normalized cross section values are quoted both in the full phase space and within the detector acceptance. The effect of final state radiation is also identified. The results are found to agree with theoretical predictions.The Drell-Yan differential cross section is measured in pp collisions at sqrt(s) = 7 TeV, from a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns.

Search for supersymmetry in pp collisions at sqrt(s)=7 TeV in events with a single lepton, jets, and missing transverse momentum

Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of 7 TeV, focusing on the signature with a single, isolated, high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum. The data sample comprises an integrated luminosity of 36 inverse picobarns, recorded by the CMS experiment at the LHC. The search is motivated by models of new physics, including supersymmetry. The observed event yields are consistent with standard model backgrounds predicted using control samples obtained from the data. The characteristics of the event sample are consistent with those expected for the production of t t-bar and W +jets events. The results are interpreted in terms of limits on the parameter space for the constrained minimal supersymmetric extension of the standard model.Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of 7 TeV, focusing on the signature with a single, isolated, high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum.
