    Gruźlica skóry — trudna diagnoza w praktyce dermatologicznej

    No full text
    Gruźlica skóry jest szczególną postacią gruźlicy o bardzo zróżnicowanym obrazie klinicznym.Nietypowość zmian skórnych oraz skąpoprątkowy przebieg choroby znacznie utrudniają postawienie prawidłowego rozpoznania i rozpoczęcie odpowiednio wcześnie leczenia. W zależności od charakteru objawów wyróżnia się gruźlicę właściwą skóry: toczniową, brodawkującą, wrzodziejącą i rozpływną oraz tuberkulidy. Zmiany skórne w przebiegu gruźlicy właściwej skóry są wynikiem bezpośredniego zajęcia skóry przez proces gruźliczy, natomiast tuberkulidy stanowią odpowiedź immunologiczną na zakażenie gruźlicze o innym umiejscowieniu. W rozpoznaniu gruźlicy skóry wykorzystuje się barwienie skrawków metodą Ziehl-Neelsena, posiew na odpowiednich podłożach, reakcję łańcuchowej polimerazy, test tuberkulinowy, testy interferonowe oraz badanie histopatologiczne zmian skórnych. Leczenie gruźlicy skóry podlega tym samym zasadom, jakie stosuje się w gruźlicy płuc, a wynik leczenia ocenia się przede wszystkim na podstawie poprawy stanu klinicznego. W niniejszej pracy przedstawiono najczęstsze postacie kliniczne, metody diagnostyczne oraz możliwości terapeutyczne gruźlicy skóry

    Search for Supersymmetry in pp Collisions at 7 TeV in Events with Jets and Missing Transverse Energy

    No full text
    A search for supersymmetry with R-parity conservation in proton-proton collisions at a centre-of-mass energy of 7 TeV is presented. The data correspond to an integrated luminosity of 35 inverse picobarns collected by the CMS experiment at the LHC. The search is performed in events with jets and significant missing transverse energy, characteristic of the decays of heavy, pair-produced squarks and gluinos. The primary background, from standard model multijet production, is reduced by several orders of magnitude to a negligible level by the application of a set of robust kinematic requirements. With this selection, the data are consistent with the standard model backgrounds, namely t t-bar, W + jet and Z + jet production, which are estimated from data control samples. Limits are set on the parameters of the constrained minimal supersymmetric extension of the standard model. These limits extend those set previously by experiments at the Tevatron and LEP colliders.A search for supersymmetry with R-parity conservation in proton–proton collisions at a centre-of-mass energy of 7 TeV is presented.
