Purpose: To study epidemiology and clinical findings of cataract in HIV+ patients.
Methods: A total of 32 HIV+ patients, 11 with uveitis/retinitis before surgery and 21 without, mean follow-up 44.9 ± 36.6 months, and 114 HIV- patients, 57 with uveitis/retinitis before surgery and 57 without, were retrospectively compared.
Results: Visual acuity improved in all HIV+ patients (p < 0.001), who were younger (p = 0.01) and more frequently males (p = 0.027). HIV+ patients with uveitis prior surgery improved less (p = 0.046) than HIV- (p < 0.001); their anterior chamber inflammation was similar to baseline. Male sex (p = 0.005), younger age (p < 0.001), dyslipidaemia (p = 0.058), HBV+ (p = 0.037), and unilateral cataract (p = 0.001) were more frequent in HIV+ patients with senile cataract, but they showed the same postoperative course as HIV- patients.
Conclusion: Cataract surgery in HIV+ patients is safe and effective. Uveitis prior to surgery did not significantly affect the postoperative course. Systemic comorbidities are more frequent in HIV+ patients with senile cataract than in HIV- subjects. 相似文献
Iatrogenic injury of the Profunda Femoris Artery (PFA) at time of hip fixation surgery can increase morbidity and mortality and prolong the hospital stay. This is an injury that tends to pass unnoticed as a cause of postoperative deterioration despite being frequently reported in the literature. Our study aims to describe the anatomy of the PFA in relation to the medial femoral cortex with specific emphasis on its orientation relative to the position of a sliding hip screw side plate construct. By doing so we are able to present clear guidance to orthopaedic surgeons on how to avoid iatrogenic PFA injury at the time of hip fracture fixation.
Methods
Using Computed Tomography Angiographic (CTA) studies, the course of the PFA in relation to the medial femoral cortex was traced in 44 patients (28 males and 16 females) with mean age of 65.6 years. Coronal and axial CT sections were cross-linked to specify the position of the PFA at 1?cm intervals.
Results
The course of the artery could be divided into three parts relative to a fixed reference point. Proximal and distal parts of the artery were in a safer position in comparison to the middle part of the artery that was found very close to the femoral cortex and along the coronal axis of the femur (mean angle 2.9° from the femoral coronal axis and 13.8?mm from the medial femoral cortex). Using the commercially available side plate constructs, this part of the artery corresponded to the distal part of the plate (third and fourth holes).
Conclusion
Special attention needs to be practiced by the operating surgeon while drilling into the third and fourth holes of the side plate. 相似文献
