RESUMO
Introduction: There is a considerable individual variation in the levels of pain-related disability among people with chronic pain. Catastrophizing pain has been proposed to explain individual differences in the level of pain-related disability. However, this relation has not been examined amongst Iranian chronic pain patients. This study aimed to investigate whether catastrophizing pain mediate the relationship between pain intensity and disability in patients with chronic pain
Methods: In this descriptive-correlational study, 209 chronic pain patients from Tehran pain clinics were selected via a convenient sampling. The participants completed the pain intencity [sub scale from Multidimensional pain inventory], physical disability and catastrophizing pain questionnaires. The collected data were analyzed using Pearson correlation and multiple hierarchical regressions
Results: There were significant relationships between catastrophizing pain and pain intensity and disability [P<0.001]. Results indicated that catastrophizing pain beliefs partially mediated the effects of pain intensity on disability [beta=0/38, p
Conclusion: catastrophizing pain is one of the important factors influencing the level of perceived disability in chronic pain patients. Therefore, in addition to the pain reduction interventions, cognitive strategies based on minimizing catastrophizing beliefs could reduce pain intensity and disability in chronic pain patients
RESUMO
To evaluate the effect of early drainage of delayed suprachoroidal hemorrhage [SCH] after glaucoma surgery. These study reports seven cases of delayed supra-choroidal hemorrhage following glaucoma surgery managed with early drainage. In this series instead of waiting for 7 to 14 days for clot lysis, the SCH was drained from the suprachoroidal space immediately after diagnosis. Seven eyes of 7 patients with delayed SCH including 4 men and 3 women were enrolled in the study. Median age was 42.57 +/- 29.61 years and mean follow up duration was 21.43 +/- 13.35 months. Immediately after diagnosis, choroidal tap and anterior chamber reformation were performed for all the patients. Intraocular pressure [IOP] decreased significantly after intervention. At final follow up, mean visual acuity was 1.08 +/- 0.31 LogMAR. Immediate surgical drainage of suprachoroidal hemorrhage seems to be an effective and safe method for treatment of delayed SCH; and it may decrease the inflammation from the entrapped blood in suprachoroidal space and reduce complications and additional procedures. Larger trials are recommended for further evaluation
