Factors influencing home modification of stroke patients.

BACKGROUND: Home modification for stroke victims is often necessary to prevent falls and enable them to have a better quality of life. Up-to-date relationship between personal factors and home modifications in post-stroke patients has not been investigated. OBJECTIVE: To identify significant personal factors influencing the requirement for home modification in post-stroke patients. STUDY DESIGN: Prospective, analytical study. MATERIAL AND METHOD: Two hundred eighty one post-stroke patients were recruited from nine tertiary rehabilitation centers in Thailand. All patients received inpatient rehabilitation programs until either they reached the rehabilitation goals or registered two consecutive stable weeks as measured by their Barthel index score. Personal factors related to home modification were assessed at study entry, during hospital stay and at discharge. The correlation between personal factors and necessities of home modification in post-stroke patients were reported through univariate and multivariate modeling. RESULTS: The results of univariate analysis showed that a low Barthel index score (< or = 14/20) (at baseline and discharge), low Brunnstrom stage of arm or leg (< or = IV/VI) at baseline, and intolerance to intensive rehabilitation programs (< 3 hr/day) indicated a necessity for modifications in the patient's home (p < 0.05). The results of multivariate modeling showed that a low Barthel index score (at baseline and discharge), and intolerance to intensive rehabilitation were significant predictors of a requirement for home modification (p < 0.05). CONCLUSION: A low level of physical functioning and intolerance to intensive rehabilitation are significant predictors for the necessity of home modifications in stroke victims.

The response pattern of intravitreal triamcinolone injection for non-AMD macular edema.

OBJECTIVE: To determine the pattern of functional and anatomical responses after intravitreal triamcinolone (IVTA) for macular edema in diabetic retinopathy, retinal vein occlusion, uveitis, and macular telangiectasia. MATERIAL AND METHOD: A Retrospective interventional study was carried out between January 2004 and July 2006. Thirty-eight eyes from 36 patients who had undergone an IVTA injection for macular edema from etiologies other than age-related macular degeneration (non-AMD macular edema) were included in the present study. Visual improvement and retinal thickness were the main outcomes. Potential complications, including increased intraocular pressure (IOP), intraocular bleeding, and postoperative endophthalmitis were also recorded. RESULTS: The mean pre-operative logarithm of Minimum Angle of Resolution (logMAR) visual acuity (VA) was 1.0 with an average macular thickness of 463.2 +/- 141.4 microns and mean IOP of 12.9 +/- 2.7 mmHg. The macular thickness rapidly decreased in the first week after an injection with a trough at two months (p < 0.001) and began to rise thereafter. The overall VA started to improve significantly at one month and lasted for two months. The IOP significantly increased from the mean baseline during the first two months in 31.6%, which could be controlled only by the medication. No other serious complications were observed. CONCLUSION: IVTA has the potential to improve both functional and anatomical outcomes in non-AMD macular edema. The decrease in macular thickness occurs from one week after an injection but the visual function improves more slowly and has a short-time effect.
