BACKGROUND: The synergistic and protective effect of platelet-rich plasma (PRP) added to methlyprednisolone (MP) has been demonstrated via in-vitro studies. However, there is no report in the literature about this issue. OBJECTIVE: The aim of this study was to evaluate clinical outcomes of intra-articular (IA) MP injection prior to PRP injection in comparison with single-dose MP and PRP injections alone in patients with knee osteoarthritis (OA). METHODS: The treatment groups were "PRP group" (n= 37) who underwent single-dose IA PRP injection, "PRP + MP group" (n= 40) who underwent MP injection one week prior to single-dose PRP injection, and "MP group" (n= 38) who underwent single-dose MP injection. Visual Analog Scale (VAS) and The Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were applied at first admission and at 1st, 3rd, 6th, and 12th month follow-ups. RESULTS: At the end of the 1st month, WOMAC score in PRP + MP group was significantly lower than PRP group. At the 3rd month, WOMAC score in PRP + MP group was significantly lower than PRP and MP groups. At the 6th month, VAS and WOMAC score in PRP + MP group was significantly lower than MP group. At the end of the 12th month, no significant difference was observed among three groups in VAS and WOMAC scores. CONCLUSION: According to our results, IA MP injection prior to PRP injection resulted in significantly better clinical outcomes compared to PRP and MP injections alone in patients who had mild to moderate knee OA.

BACKGROUND: Low back pain (LBP) is a public health problem commonly seen in all societies. OBJECTIVE: The aim of this study was to determine the prevalence and specific risk factors of low back pain (LBP) in the central and outlying districts of the province of Trabzon, a Black Sea region of Turkey. METHOD: A random sample of 7897 (4006 men and 3789 women) adults was collected by using sampling techniques of stratification. In this study questionnaires were completed at face-to-face interviews with participants selected on the basis of place of residence, gender and age group. The used variables in this study were: use of cigarettes, status of marriage, level of education, and presence of chronic disease, the prevalence of lifetime LBP and of LBP in the preceding year. Chronic LBP was determined as being present for more than 6 weeks. RESULTS: The lifetime prevalence of LBP in the general population was determined at 62.1%. Prevalence in the preceding year was 46.1%, and that of LBP lasting more than six week was 18.1%. Lifetime prevalence of LBP, prevalence of LBP in the preceding year and prevalence of pain lasting more than six week were all statistically significantly higher in women (p < 0.001). Use of cigarettes, female gender, marriage, a low level of education and presence of chronic disease were identified as independent risk factors for LBP (p < 0.001). CONCLUSION: Lower back pain is a common public health problem. Recommendations were made for local health services to prevent LBP, including health education through combating chronic diseases, reducing cigarette consumption, improvement of working environments and life styles.
