RESUMO

PURPOSE: The Zurich Claudication Questionnaire (ZCQ) is a self-administered measure to evaluate symptom severity, physical function, and surgery satisfaction in lumbar spinal stenosis (LSS). The purpose of this study is to assess the psychometric properties of the Japanese ZCQ in LSS patients. METHODS: LSS patients who are scheduled to undergo surgery were recruited from 12 facilities. Responses to several questionnaires, including the Japanese ZCQ; the visual analogue scale (VAS) to evaluate the degree of pain in the buttocks/legs, numbness in the buttocks/legs, and low back pain; the Oswestry Disability Index (ODI); and the SF-36v2, were collected before surgery and again 3 months after surgery (the post-surgery ZCQ was administered twice for test-retest reliability). For reliability, test-retest reliability was evaluated using the intra-class coefficient (ICC) and internal consistency was evaluated using Cronbach's alpha coefficient. Concurrent validity was assessed using Spearman's correlation coefficients between the Japanese ZCQ and other questionnaires. Effect size (ES) and standard response mean were calculated for responsiveness. All analyses were performed individually for the Japanese ZCQ symptom, function, and satisfaction domains. RESULTS: Data from 180 LSS patients were used in this analysis. The ICCs were 0.81, 0.89, and 0.88 and Cronbach's alpha coefficients were 0.78, 0.84, and 0.92 for the Japanese ZCQ symptom, function, and satisfaction domains, respectively. Regarding the concurrent validity, strong correlations (±0.5) were demonstrated between the Japanese ZCQ domains and the VAS leg pain, ODI, and SF-36v2 physical functioning or bodily pain, whereas correlations were approximately 0.3 in scales measuring other symptoms that are less related to symptom, function, or satisfaction domains. ESs showed high values for the ZCQ symptom and function domains (-1.73 for both). CONCLUSIONS: These psychometric assessments demonstrate that the Japanese ZCQ is a psychometrically reliable and valid measure in LSS. The Japanese ZCQ can evaluate both multi-dimensional aspects and the level of surgery satisfaction.

RESUMO

OBJECTIVES: Saito et al. isolated novel mycobacterium strains from the sputum of 12 patients with pulmonary disease. They reported, that the strains were clearly different from Mycobacterium tuberculosis (TB) in cultural, biochemical and immunological properties, despite the high homology (99.1%) of the 16S rRNA gene sequence between the two. Recently, we isolated four strains having similar properties as the above strains among mycobacterial strains that were sent to the Research Institute of Tuberculosis for identification. We examined these isolates using commercial systems for identification of mycobacteria. MATERIALS: Four strains of the unidentified mycobacteria were used in this study. METHODS: Tests used in the study included cultural on solid media, biochemical characteristics, DNA sequence analyses of 16S rRNA and rpoB genes, TRC, COBAS AMPLICOR, COBAS TaqMan, MTD, DDH, Accu-Probe, Capilia TB, and a drug susceptibility tests. RESULTS: After three weeks of culture, smooth and non-photochromogenic colonies were formed. The niacin accumulation test was negative. The homologies of DNA sequence between the new strains and M. tuberculosis for 16S rRNA and rpoB genes were 97.8% and 90.2%, respectively. The tests with TRC and MTD kits were positive, whereas the tests with AMPLICOR, TaqMan, Accu-Probe and Capilia TB kits were negative. The organism was not identified with the DDH system.
