RESUMEN
To investigate the effects of diclofenac alone or when combined with alpha-tocopherol on the oxidative activity of polymorphonuclear leukocytes [PMNs] in healthy and osteoarthritic [OA] patients. The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Twelve healthy controls and 12 osteoarthritic patients were recruited to the study. Twelve healthy controls and osteoarthritic patients were given diclofenac 50 mg thrice daily orally, initially for 5 days then alpha-tocopherol at 200 mg thrice daily orally, was added for another 5 days. Blood samples were drawn before the start of the study [pre-treatment] and at 5 days following treatment with diclofenac alone and 10 days following treatment with diclofenac and alpha-tocopherol. Chemiluminescence [CL] response was measured for whole blood and isolated polymorphonuclear leukocytes [PMNs] on all samples. Diclofenac enhanced CL response of whole blood and of PMNs of healthy controls when stimulated with phorbol myristate acetate [PMA] and opsonized zymosan [OPZ]. Co-treatment with alpha-tocopherol resulted in no appreciable change in the CL response of whole blood when stimulated with PMA or OPZ but a further significant enhancement of CL response of isolated PMNs when these cells were stimulated by either PMA or OPZ. In osteoarthritic patients, diclofenac alone and when combined with alpha-tocopherol showed no significant change in CL response of whole blood. The CL response of PMNs from OA patients was decreased by diclofenac alone. However, this inhibitory effect was not observed when alpha-tocopherol was used together with diclofenac. The effect of diclofenac alone or in combination with alpha-tocopherol did not produce a consistent effect on the CL response of whole blood or isolated PMNs of healthy or osteoarthritic patients

To estimate the prevalence of mouth and genital ulceration in the community and its relationship to rheumatic diseases. A house to house survey was carried out over a period of 18 months extending from September 1993 to February 1995, on 5,894 individuals utilizing detailed questionnaires on symptoms of musculoskeletal diseases and associated symptoms including history of mouth, genital ulcers, eye symptoms, and skin changes. After the initial phase, a 2nd phase was completed by trained nurses and paramedical staff, the purpose of which was to explore in detail, the history of those responding positively to any of the questions in phase one. The 3rd stage was conducted by general practitioners and rheumatologist to interview and examine those identified in phase 2 at King Fahad Hospital, Buraidah, Kingdom of Saudi Arabia. We identified 7 [0.1%] cases of genital ulceration, 43 [0.7%] cases of mouth ulceration, 263 [4.5%] cases of reddish eye or blurred vision, and 124 [2.1%] cases of skin rashes. Only 2 cases had both mouth and genital ulceration in addition to eye disease, skin rash and musculoskeletal pain. There was significant correlation between mouth ulcers and skin rash, eye symptoms, genital ulcerations, male sex, single status, weight loss and backpain. The vast majority of mouth and genital ulcers are not associated with a known rheumatic disease

The aim of this study was to estimate the prevalence of back pain in the adult population of Al-Qaseem Central Province, Kingdom of Saudi Arabia and to find associated features and factors. A house-to-house survey covering 1,000 household in the towns and villages of Al-Qaseem province was carried out over a period of 18 months extending from September 1993 until the end of February 1995. A total of 5,894 adults, aged 16 years and above, were questioned by trained staff regarding back pain, and the demographic data in addition to general, medical and social history. A response was obtained in 5,743 [97.4%]. Their mean age was 34.14 ' 15.16 [range 16-99]. Back pain was reported by 1,081 [18.8%], wherein 499 [8.8%] were men, and 574 [10%] were women. Back pain was more prevalent in married [23.3%] individuals than unmarried [6.4%]. Adjusted odds ratio [OR] for back pain in married individuals was 1.88 [95% confidence intervals [CI] 1.49-2.37]. Back pain was strongly correlated with age [correlation coefficient = 0.378 P < 0.01]. It also showed significant correlation with weight and height, depression, family history of back pain, change in work ability, frequency of attendance at local doctor, use of medication and lower education level. The association with body mass index became evident only after comparing the heaviest 20th percentile to the lightest [OR 1.335 [95% CI, 1.279-1.402]]. Certain occupational status [unemployed, farmers, professional workers and housewives] were associated with back pain. Back pain was relatively common in this largely unindustrialized community although its prevalence is lower than reported from some western countries

To estimate the prevalence of musculoskeletal [MSK] pain in Al-Qaseem province in central Saudi Arabia. Over a period of 18 months extending from September 1993 through to the end of February 1995, a house-to-house survey was conducted in Al-Qaseem province and included 5,894 adults asking regarding musculoskeletal pain. We obtained a response from 5,823 [98.8%], 2,667 [45.8%] men, and 3,156 [54.2%] women. The mean age was 34.14 +/= 15.16 years. Musculoskeletal pain was reported by 1,477 [25.4%], 762 [13.1%] men and 715 [12.3%] women. Musculoskeletal pain was significantly correlated with age [r =0.454], married status [r=0.238], unemployment [r=0.122], lower educational attainment [r=0.347], frequent attendance at local doctor [r=0.703], consumption of medications for pain [r =0.551], and change in ability to work [r=0.492]. We found no association with sex or body mass index. Musculoskeletal pain, although common in the community, is less prevalent than reported from Western countries, but has similar socio-medical consequences

One hundred and sixty four patients with various underlying diseases were screened for the presence of antibodies to the spirochete Borrelia burgdorferi using immunofluorescence antibody [IFA] assay followed, in positive cases, by enzyme-linked immunoassay [ELlSA]. Five patients showed serological evidence of possible exposure to the spirochete. Only one patient had a positive rheumatoid factor and none had a positive rapid plasma reagin [RPR] or Trepenoma pallidum hemagglutination test [TPHA]. Thus, we conclude that there is preliminary serological evidence suggestive of exposure to B. burgdorferi and possibly Lyme disease in Saudi Arabia
