Isolated fallopian tube torsion: A rare diagnosis in a perimenopausal patient with adnexal mass and raised Ca 19-9: Endoscopic management and review

Isolated torsion of the fallopian tube in perimenopausal women is very rare. A patient who presented with an adnexal mass with possible ovarian torsion and with a raised Ca 19-9 titer is reported. A 48-year-old perimenopausal woman had acute lower right abdominal pain accompanied by nausea and vomiting. Ultrasonographic studies revealed a multiloculated cystic mass in the right adnexum, and Ca 19-9 was raised. The symptoms worsened, and emergency laparoscopy and salpingoophorectomy were performed. Histology revealed isolated fallopian tube torsion with a benign ovarian cyst. Torsion of the fallopian tube, although rare, should always be considered as part of the differential diagnosis of any symptomatic pelvic mass, even in a perimenopausal woman. Characteristic ultrasonographic and CT findings have been reported, an early diagnosis can be made, and an endoscopic, less radical procedure will be the treatment of choice resulting in shorter hospitalization, increased patient satisfaction, and more cost benefits. © Springer-Verlag 2005

Shape, transverse size, and charged-hadron multiplicity of jets in pp collisions at sqrts=7;TeV sqrt {s} = 7;TeV

Measurements of jet characteristics from inclusive jet production in proton-proton collisions at a centre-of-mass energy of 7 TeV are presented. The data sample was collected with the CMS detector at the LHC during 2010 and corresponds to an integrated luminosity of 36 inverse picobarns. The mean charged hadron multiplicity, the differential and integral jet shape distributions, and two independent moments of the shape distributions are measured as functions of the jet transverse momentum for jets reconstructed with the anti-kT algorithm. The measured observables are corrected to the particle level and compared with predictions from various QCD Monte Carlo generators.Comment: Replaced with published version. Added journal reference and DOI. Supplementary data tables availabl

Measurement of the Lambda(0)(b) lifetime in pp collisions at root s=7 TeV

A measurement of the Lambda(0)(b) lifetime using the decay Lambda(0)(b) -> J/psi Lambda in protonproton collisions at root s = 7TeV is presented. The data set, corresponding to an integrated luminosity of about 5 fb(-1), was recorded with the CMS experiment at the Large Hadron Collider using triggers that selected dimuon events in the J/psi mass region. The Lambda(0)(b) lifetime is measured to be 1.503 +/- 0.052 (stat.) +/- 0.031 (syst.) p
