Two cases of listeria rhombencephalitis

Listeria rhombencephalitis (LRE) is a rare encephalitis of the hindbrain that can present with a variety of neurological symptoms. It is a diagnostic challenge, but prompt antimicrobial therapy is important to prevent high rates of mortality and morbidity. We report two cases of LRE, with several contrasting clinical features and different disease courses. Despite being rare, it is important to consider listeria in patients with possible meningoencephalitis, even if cultures are negative. Empirical treatment of meningoencephalitis should provide coverage for listeria, especially if the patient is at risk of listeriosis or there is a potential history of listeria exposure.</p

The use of 3D printed paediatric temporal bones as a training tool

Introduction: Temporal bone dissection is an essential component of otological training. The ideal temporal bone training platform should allow the surgeon to prepare and undertake the actual operative procedure required prior to the operation on the patient. Paediatric temporal bones are generally not available or used due to ethical issues and availability.Methods: Using specialised computer programmes and non-identifiable paediatric high resolution computed tomography (HRCT) scans of temporal bones 3D printing of paediatric temporal bones has been trialled.Results: 3D printing of paediatric temporal bones has proved both an economical and anatomically accurate tool for training. Using HRCT scans to print from allows cases of appropriate complexity to be selected. Conclusion: 3D printed temporal bones from HRCT images provide optimal opportunities for paediatric temporal bone training and allow for more accurate delineation of structures. Furthermore, they provide improved haptics through choice of appropriate material, especially in complex cases and where anatomy may be difficult

Cross-sections and leptonic forward-backward asymmetries from the Z0 running of LEP

During 1993 and 1995 LEP was run at 3 energies near the Z0 peak in order to give improved measurements of the mass and width of the resonance. During 1994, LEP operated only at the Z0 peak. In total DELPHI accumulated data corresponding to an integrated luminosity of approximately 116 pb-1. Analyses of the hadronic cross-sections and of the cross-sections and forward-backward asymmetries in the leptonic channels used the most precise evaluations of the LEP energies. In the dimuon channel, events with a photon radiated from the initial state have been used to probe the cross-sections and asymmetries down to PETRA energies. Model independent fits to all DELPHI lineshape and asymmetry data from 1990 to 1995 have been carried out giving values of the resonance parameters: MZ = 91.1863 ± 0.0028 GeV ΓZ = 2.4876 ± 0.0041 GeV σ0 = 41.578 ± 0.069 nb R1 = 20.730 ± 0.060 AFB0 = 0.0187 ± 0.0019. These values are significantly more precise than those previously published. The results are interpreted in terms of the Standard Model.0SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Searches for neutral Higgs bosons in e+e- collisions around √s = 189 GeV

Searches for neutral Higgs bosons in the Standard Model and the MSSM have been performed using data collected by the DELPHI experiment at a centre-of-mass energy of 188.7 GeV, corresponding to an integrated luminosity of 158 pb-1. These analyses are used, in combination with our results from lower energies, to set new 95% confidence level lower mass bounds on the Standard Model Higgs boson (94.6 GeV/c2) and on the lightest neutral scalar (82.6 GeV/c2) and neutral pseudoscalar (84.1 GeV/c2) Higgs bosons in a representative scan of the MSSM parameters. The results are also interpreted in the framework of a general two-Higgs doublet model.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
