Translation, cross-cultural adaptation and validation of the English Lequesne Algofunctional index in to Bengali.

BACKGROUND: This study was focused on translation and cultural adaptation of the English Lequesne Algofunctional index (LAI) into Bengali for patients with primary knee osteoarthritis (OA) and testing reliability and validity of the Bengali version of the LAI. METHODS: This study was carried out in the Department of Rheumatology, BSM Medical University, Dhaka, Bangladesh. Using the forward-backward method the English LAI was translated into Bengali including cultural adaptation. For pretesting, A sample of 40 patients with primary knee osteoarthritis were screened using the Bengali version of LAI. Following the pretest, 130 consecutive patients with symptomatic knee OA completed the interviewer administered Bengali LAI, the validated Bengali version of SF-36, Visual Analogue Scale for Pain, Distance Walked and Activities of Daily Living. For the retest 60 randomly selected patients from the cohort were administered the Bengali LAI 7 days later. An item by item analysis was performed. Internal consistency was assessed by Cronbach's alpha, test-retest reliability by intraclass correlation coefficient (ICC) and Kappa coefficient, construct validity was measured using the Spearman rank correlation coefficient. RESULTS: It took 3.25 ± 0.71 min to complete the Bengali LAI and the mean score was 9.23 ± 4.58. For the Bengali LAI Cronbach's alpha score was 0.88, test-retest reliability assessed by ICC was 0.97. For construct validity, excellent convergent validity was achieved (ρ = 0.93) but the divergent validity was moderate (ρ = 0.43). CONCLUSIONS: The Bengali LAI showed excellent convergent validity, internal consistency and test-retest reliability, only the divergent validity was moderate. So, the Bengali LAI can be applied as a HRQoL assessment tool for primary knee OA patients.

The knowledge level of rheumatoid arthritis patients about their disease in a developing country. A study in 168 Bangladeshi RA patients.

OBJECTIVES: To assess disease-related knowledge of rheumatoid arthritis (RA) patients PATIENTS AND METHODS: Consecutive RA patients were invited from the rheumatology departments of BSMM University, Dhaka, Bangladesh. The Bangla version of the Patient Knowledge Questionnaire (B-PKQ) was used. Correlations between the B-PKQ scores and clinical-demographic data were measured using Pearson's correlation coefficient. Impact of independent variables on the level of knowledge about RA was analyzed through multiple regression analysis. Possible explanatory variables included the following: age, disease duration, formal education level, and Bangla Health Assessment Questionnaire (B-HAQ) score. Analysis of variance (ANOVA) was used to test the difference between demographical, clinical, and socioeconomic variables. For statistical analysis, SPSS statistics version 20 was used. RESULTS: A total of 168 RA patients could be included. The mean B-PKQ score was 9.84 (range 1-20) from a possible maximum of 30. The mean time for answering the questionnaire was 24.3 min (range 15-34). Low scores were observed in all domains but the lowest were in medications and joint protection/energy conservation. Knowledge level was higher (15.5) in 6 patients who had RA education before enrollment. B-PKQ showed positive correlation with education level (r = 0.338) and negative correlation with HAQ (r = -0.169). The B-PKQ showed no correlation with age, disease duration, having first degree family member with RA, education from other sources (neighbor, RA patient, nurses), or information from mass media. CONCLUSIONS: Disease-related knowledge of Bangladeshi RA patients was poor in all domains. Using these findings, improved education and knowledge will result in better disease control.Key Points• Little is known about the knowledge of RA patients regarding their disease and its treatment in Bangladesh and in developing countries in general.• We found that the knowledge of Bangladeshi RA patients regarding their disease was poor in all domains; it correlated positive with education level and negative with function (HAQ), but showed no correlation with age or disease duration.• The findings of this study can be used for improving current patient education programs by health professionals and through mass media.• Better disease control of RA may be achieved by improving patient knowledge in a developing country like Bangladesh, but also in other parts of the world.

Piriformis pyomyositis, a cause of piriformis syndrome-a systematic search and review.

Piriformis pyomyositis is a rare form of purulent skeletal myositis. As previous studies concerning piriformis pyomyositis had lower level of evidence and no systematic review has been published yet, we performed a systematic search to review and describe causes, symptoms, red flags, and available treatment options for piriformis pyomyositis. Using PubMed and PubMed Central databases, we found 21 articles describing 23 cases of piriformis pyomyositis. Based on the retrieved information, alongside acute sciatica like buttock and/or hip pain, high-grade fever, aggressive deep seated gluteal pain, neurological deficit of sciatic nerve distribution, positive straight leg raising test, and raised inflammatory biomarkers (erythrocyte sedimentation rate, ESR, C-reactive protein, CRP) provide clues for diagnosis of piriformis pyomyositis. Some cases were very ill but no death was documented. Staphylococcus aureus was the most common pathogen, but Group A as well as Group ß Streptococcus, Salmonella typhi, Proteus mirabilis, Brucella melitensis, and Escherichia coli were also involved in the disorder. To treat the piriformis pyomyositis, broad-spectrum antibiotics were found to be useful; however, sometimes, antibiotic switching was warranted based on blood and tissue aspirate reports. Drainage and/or surgical exploration of the affected piriformis muscle were required in cases where antibiotics appeared ineffective. Piriformis pyomyositis is a rara avis and performing of prospective studies will hardly be feasible.

Musculoskeletal symptoms and disorders among 350 garment workers in Bangladesh: A cross-sectional pilot study.

OBJECTIVE: To study the prevalence of musculoskeletal (MSK) symptoms and disorders among garment workers in Bangladesh, to look for possible relationships between pain location and type of work performed and to estimate the prevalence of rheumatological diagnoses. METHODS: A cross-sectional pilot study among 350 garment workers using the COPCORD (Community Oriented Program for Control of Rheumatic Disorders) methodology. Subjects with musculoskeletal pain were examined by rheumatologists for rheumatological diagnosis. The workers were classified into cutting, sewing, finishing and quality control operators. RESULTS: Most of the workers were aged below 35 years (88%) and females (82.9%) and the majority had only primary education (74.6%). The prevalence of MSK pain within 7 days of the interview was 77.1%, a much higher figure than in the general population. The most affected sites were: shoulder (17.9%), lower back (15.2%), neck (13.8%) and knee (10.8%). Multiple regional pain was the commonest finding in 173 of 350 workers. In this pilot study rheumatoid arthritis was diagnosed in 0.9%, undifferentiated arthritis in 1.1%, nonspecific low back pain in 4.6%, soft tissue rheumatism in 3.7%, osteoarthritis in 0.9% and lumbar spondylosis in 1.1%, figures comparable with those observed in the general population; spondyloarthropathy was seen more often, in 1.42%, possibly explained by the small numbers. CONCLUSIONS: Musculoskeletal pains are common among garment workers of Bangladesh and may cause morbidity, disability, and work loss. Our findings may be important to plan ergonomic measures preventing complaints and may be of interest for international companies ordering garments in Bangladesh.
