Evaluation of the Turkish version of the Bath Ankylosing Spondylitis Patient Global Score (BAS-G).

The objective of this study was to investigate the reliability and validity of the Turkish version of the Bath Ankylosing Spondylitis (AS) Patient Global Score (BAS-G). Seventy-one consecutive patients with AS were enrolled into the study. Patients were requested to fill in the questionnaire on the day of admission (first visit), on a second occasion within 24 h after admission (second visit) for test-retest reliability analysis, and on a third occasion for assessing sensitivity to change. Construct validity was assessed by correlation analysis with the Bath AS Functional Index (BASFI), Dougados Functional Index (DFI), Dougados Articular Index (DAI), physical examination findings, and several other parameters. Test-retest reliability analysis of individual BAS-G scores at initial and second visits showed good intraclass correlations [n=46, intraclass correlation=0.928 (0.870-0.960) and intraclass correlation=0.853 (0.725-0.920), for 1-week and 6-month scores, respectively]. Both 1-week and 6-month scores showed moderate correlations with the BASFI (r=0.586 and r=0.503, respectively, P=0.000 for both). The 1-week score also showed moderate correlation with the DFI (r=0.530, P=0.000). The 1-week score showed weak correlations with finger-to-floor distance (r=0.263, P=0.027), chest expansion (r=-0.245, P=0.039), and DAI (r=0.271, P=0.036). Change in the 1-week score at the third visit showed good correlation with the BASFI score (r=0.670, P=0.000, n=36) and moderate correlation with the DFI (r=0.440, P=0.017, n=29). The Turkish version of the BAS-G has good reliability and validity. It is a good tool for assessing patients with AS or other rheumatic diseases in clinical practice and research.

Evaluation of the Turkish version of the Dougados functional index in ankylosing spondylitis.

UNLABELLED: To investigate the reliability and validity of the Turkish version of the Dougados functional index (DFI) in patients with ankylosing spondylitis (AS). The Turkish version of DFI was obtained after a translation and back-translation process. Seventy consecutive patients with AS were enrolled. Patients were requested to complete the questionnaire on the day of admission (first visit), a second time within 24 h after admission (second visit), and on a third occasion. Reliability, validity and reproducibility of the Turkish version of the index were assessed. All the items showed significant correlations with the total index score with r-values ranging from 0.516 to 0.817. Cronbach alpha score was calculated as 0.908. Significant correlations were found between the total DFI score and Schober test (r=-0.293, P<0.05), occiput-wall distance (r=0.384; P<0.01) finger-to-floor distance (r=0.450, P<0.001), chest expansion (r=-0.331, P<0.01) and Dougados articular index (r=0.352, P<0.05). Good correlations were found between individual DFI items and the total score (r=between 0.533 and 0.882, p< 0.001) for the first and second visits, showing good reproducibility of the index. CONCLUSION: the Turkish version of DFI has good reliability, validity and reproducibility, confirming its utility for trials in Turkish AS patients.

Giant renal hydatid cyst resembling a simple cyst: an intraoperative diagnosis.

An interesting case of a giant renal hydatid cyst is presented. The big cystic mass detected at ultrasonography (US) and computerized tomography (CT) in a ten-year-old girl looked like a simple cyst. No germinative membrane or any other radiological sign of a hydatid cyst was present. The operation was planned for a simple cyst; but was altered, after an intraoperative diagnostic needle sampling brought out the characteristic fluid of hydatid cyst. We came to the conclusion that hydatid cystic masses may not always present with their characteristic radiological findings; and that extreme caution should be practiced by the radiologist and the surgeon in order to prevent iatrogenic echinococcal dissemination.

The Turkish version of the Bath Ankylosing Spondylitis Functional Index: reliability and validity.

The purpose of this study was to investigate the reliability and validity of the Turkish version of the Bath Ankylosing Spondylitis (AS) Functional Index (BASFI). The Turkish version of the BASFI was obtained after a process of translation and back-translation. Eighty-one consecutive patients meeting the 1984 New York criteria for AS were enrolled. Patients were evaluated and requested to complete the questionnaire at days 1 and 2 and on a third occasion between days 15-90. Reliability, reproducibility, validity and sensitivity to change of the Turkish version of the index were assessed. Each score correlated closely with the index score, with coefficients between 0.727 and 0.844. Reliability analysis showed a Cronbach's alpha score of 0.926. Correlations were found between all items of the BASFI and Schober's test (r=-0.258 to -0.531, p<0.001-0.05), occiput-to-wall distance (r=0.284 and 0.589, p<0.001-0.05), and finger-to-floor distance (r=0.334 to 0.613, p<0.001-0.01). The total index score was correlated with the number of nocturnal awakenings (r=0.515, p<0.001), Schober's test (r=-0.444, p<0.001), finger-to-floor distance (r=0.567, p<0.001), occiput-to-wall distance (r=0.535, p<0.001), chest expansion (r=-0.403, p<0.001), and the Dougados articular index (r=0.371, p<0.01). A good correlation was found between day 0 and 1 BASFI indices (r=0.765-0.917, p<0.001), showing good reproducibility of the index. The Turkish version of the BASFI showed reliability, reproducibility, and validity, confirming its utility in the research of AS in Turkey. However, sensitivity to changes due to drug therapy and/or rehabilitation remains to be determined.

The association between cervical rib and sacralization.

STUDY DESIGN: After determining the normal reference values for the length of the transverse processes of the seventh cervical vertebra, the association between the presence of cervical rib and sacralization was investigated. OBJECTIVE: To determine the length of cervical rib and search for any association between cervical rib and sacralization. SUMMARY OF BACKGROUND DATA: Both cervical ribs and sacralization have been noted in some patients in the authors' clinical practice. METHODS: The cervical rib is a supernumerary rib arising from a cervical vertebra, or it might be simply an elongation of the transverse process of the seventh cervical vertebra. However, there is no consensus about a specified length of this process. For reference values, anteroposterior cervical radiographs of 210 normal individuals (112 male, 98 female, mean age 33.9 +/- 10.1 years, range 19-61 years) were taken, and elongation of the transverse processes beyond 2 standard deviations (30 mm) was considered as cervical rib. In the guide of the reference values, 324 outpatients (165 male, 159 female, mean age 42.0 +/- 14.6 years, range 17-85 years), having cervical ribs or sacralization detected by plain radiographs, were taken as the study group. As control 729 volunteers (364 male, 365 female, mean age 41.7 +/- 14.3 years, range 15-76 years) were studied. RESULTS: In 1053 patients, of 471 patients having cervical ribs, 345 (73.2%) had also sacralization; of 536 patients with sacralization, 345 (64.4%) also had cervical ribs. Significant associations were found between cervical rib with or without articulation and sacralization [chi2 = 52.284, P < 0.001, odds ratio 5.097 (3.156-8.234); chi2 = 139.473, P < 0.001, odds ratio 5.204 (3.922-6.905), respectively]. CONCLUSION: Presence of cervical rib might be a clue to the existence of sacralization or vice versa. In patients with cervical or lumbar pain, this association may be helpful for differential diagnosis before applying sophisticated diagnostic techniques.
