RESUMO
OBJECTIVE: This study assesses the prevalence of musculoskeletal (MSK) pain in patients attending primary care clinics in a medium-sized town in Malaysia and examines the interventions given for the symptoms and the level of the associated disabilities. METHOD: This investigation comprises a cross-sectional descriptive study of all patients visiting two primary care clinics aged 18 years and above. Patients presenting with joint pain answered a questionnaire assessing demographic data, disabilities (measured by the Stanford HAQ-DI), and treatment options. RESULTS: Of 1,074 patients surveyed, 202 (18.8%) had MSK complaints. The mean age of those with MSK pain was 56.1 years. Incidence increased with age, reaching 78.8% of those over 48 years of age. The knee was the most common site of MSK pain (52.2%), with 20.3% requiring referral for specialist assessment. The median HAQ score was 0.375 and 89.6% of those surveyed had mild disability. CONCLUSION: MSK pain is a common problem among patients visiting primary care clinics. The most common site of MSK pain was the knee. On formal assessment, the majority of these patients exhibited mild disability. A significant proportion of patients still required specialist referral. This finding would suggest a need for further training on the management of MSK disease at the primary care level to avoid over-burdening the secondary care services.
RESUMO
BACKGROUND: Hydroxychloroquine (HCQ) is widely used for long-term treatment of autoimmune diseases such as rheumatoid arthritis. However, its long-term use is known to be associated with visual changes due to retinal damage. Retinal damage associated with long-term HCQ therapy is preventable if the drug is discontinued early when the patients are still asymptomatic. In view of contrasting reports from previous studies, we investigated the association of prolonged HCQ therapy with retinal thickness in macular area. METHODS: This study included 48 patients on long-term HCQ therapy and 38 healthy controls. All subjects underwent examination for corrected visual acuity, fundus photography, visual fields and SD-OCT for retinal thickness. RESULTS: Visual acuity, visual fields, fundus photography and SD-OCT did not reveal changes consistent with diagnosis of established HCQ retinopathy in any of the subjects from HCQ group. Retinal thickness in central, parafoveal and perifoveal areas did not show significant differences between HCQ and control groups. However, we observed negative correlation between cumulative dose and retinal thickness in the parafoveal (p = 0.003) and perifoveal areas (p = 0.019) but not in the central area. CONCLUSIONS: Correlation of cumulative dose with retinal thickness in parafoveal and perifoveal areas and not the central area is in accordance with the late appearance of HCQ-induced bull's eye retinopathy. Hence screening of asymptomatic patients using OCT seems to be of great importance for early detection of retinal changes.
