The objective of this study is to determine the intraobserver and interobserver reliability of end vertebra definition and Cobb angle measurement using printed and digital radiographs of 48 patients with scoliosis. The Cobb angle and the end vertebra were assessed by six observers in 48 patients with scoliosis using printed and digital radiographs.(More)
Cervical disc arthroplasty has become a commonplace surgery for the treatment of cervical radiculopathy and myelopathy. Most manufacturers derive their implant dimensions from early published cadaver studies. Ideal footprint match of the prosthesis is essential for good surgical outcome. We measured the dimensions of cervical vertebrae from computed(More)
The aim of this study was to evaluate balance abilities and electromyographic (EMG) latency times of the preferred and nonpreferred leg in soccer players. Whereas side differences between the two legs in force, kicking speed, and joint laxity have been demonstrated in athletes in previous studies, no data are so far available on balance differences. Low(More)
Reverse transcriptase polymerase chain reaction for the detection of tyrosinase-mRNA-positive cells in peripheral blood of melanoma patients, as a possible marker of hematogenous dissemination, has demonstrated varying detection rates. This study examined the sensitivity and reproducibility of the technique using a protocol of multiple polymerase chain(More)
OBJECTIVE The study's objective was to test the tolerability and efficacy of the endogenous antiseptic N-chlorotaurine (NCT) in comparison with a standard clinical treatment according to a phase IIb clinical trial protocol. STUDY DESIGN The antimicrobial agent NCT was compared with the antibiotic component drops Otosporin (containing neomycin, polymyxin(More)
OBJECTIVES The new endogenous substance N-chlorotaurine (NCT), which for the first time was synthesized and introduced into clinical practice by our research group, was now used for postoperative ear care following tympanoplasty. The antiseptic and drying effect of NCT was evaluated and compared to the standard postoperative procedure in our department. (More)
STUDY DESIGN This study was designed as a cohort study comparing a prospective sample to a historic control group. OBJECTIVE The aim of the actual trial was to compare the rate of cement leakage by quantitative volumetry comparing viscosity-controlled and non-viscosity-controlled vertebroplasty. SUMMARY OF BACKGROUND DATA Percutaneous vertebroplasty(More)
OBJECTIVE To test the antibacterial properties of the topical corticoid mometasone furoate, which is used as a nasal spray. DESIGN The activity of mometasone (0.01%, 0.1%, and 0.5%) in buffer solution against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Streptococcus pyogenes, and Streptococcus milleri was tested by quantitative(More)
The absence of uniformity, the use of different terminologies, and the diversity of methods used to translate numerical data into clinical outcomes have been described as potential problems when dealing with clinical knee scores for total knee arthroplasty (TKA). Gait analysis is believed to provide more objective parameters. The aim of the present study(More)
