European multi-centre study of the Nucleus Hybrid L24 cochlear implant
Item does not contain fulltextOBJECTIVES: To investigate the preservation of residual hearing in subjects who received the Nucleus Hybrid L24 cochlear implant. To investigate the performance benefits up to one year post-implantation in terms of speech recognition, sound quality, and quality of life. DESIGN: Prospective, with sequential enrolment and within-subject comparisons. Post-operative performance using a Freedom Hybrid sound processor was compared with that of pre-operative hearing aids. STUDY SAMPLE: Sixty-six adult hearing-impaired subjects with bilateral severe-to-profound high frequency hearing loss. RESULTS: Group median increase in air-conduction thresholds in the implanted ear for test frequencies 125-1000 Hz was /= 20 percentage points/2 dB SNR). Mean SSQ subscale scores were significantly improved (+ 1.2, + 1.3, + 1.8 points, p < 0.001), as was mean HUI3 score (+ 0.117, p < 0.01). Combining residual hearing with CI gave 22-26 %age points mean benefit in speech recognition scores over CI alone (p < 0.01). CONCLUSIONS: Useful residual hearing was conserved in 88% of subjects. Speech perception was significantly improved over preoperative hearing aids, as was sound quality and quality of life

The accuracy of methods for urate crystal detection in synovial fluid and the effect of sample handling: A systematic review
This study aims to compare different methods of monosodium urate crystal (MSU) detection in synovial fluid (SF) and the effect of sample storage and handling on crystal detection. A systematic literature search was performed in MEDLINE, EMBASE, the Cochrane Library and the American College of Rheumatology/European League Against Rheumatism conference abstracts of 2010 and 2011. Studies that compared a method for detecting MSU crystals in SF with polarised light microscopy (PLM) or compared various SF storage and handling factors with the detection of MSU crystals as an outcome were included. Twelve studies out of 247 identified references were included in the review. Seven studies compared different methods of MSU crystal detection in SF with PLM. Due to study heterogeneity, methodological limitations and risk of bias, no firm conclusions could be drawn from the available data. Five studies examining SF storage and handling factors were identified. A reduction in MSU crystal concentration was observed over time at room temperature that was not seen in refrigerated samples. The use of anticoagulation as a storage medium provided no benefit. Dried cytospin preparations appeared to be a suitable medium for long-term storage and delayed crystal analysis for at least 12 months. The existing data do not provide a compelling argument for the replacement of PLM as the current standard. SF sample storage and handling have an effect on MSU crystals and may impact on the reliability of analysis.S. W. Graf, R. Buchbinder, J. Zochling, S. L. Whittl
