One hundred and thirty patients with uveitis in north-western zone of our country were analyzed based on anatomical classification and their causes. It was found that anterior uveitis was the commonest type in uveitis,accounting for 86.15% of total patients. Intermediate uveitis, pan-uveitis and posterior uveitis accounted repectively for 6.92%, 3.85%and3.08% of the total patients. Rheumatic arthritis was the most frequently accompanied systemic disease in patients with uveitis,showing a possibly causative link between them in their pathogenesis. （Chin J Ocul Fundus Dis,1994,10:156-158）
ObjectiveTo explore the cause of prosthesis dislocation after primary artificial hip replacement (AHR) and propose preventive measures. MethodsA total of 221 patients underwent artificial hip replacement from 2000 to 2012, among whom 8 developed dislocation. These cases were retrospectively analyzed to summarize the causes of dislocation and preventive measures were proposed. ResultsAmong 221 cases of hip replacement, 8 suffered from postoperative dislocation. All of them underwent posterolateral-approach total hip arthroplasty. The causes of dislocation included coexisting decreased muscle strength before operation, improper placement of the prosthesis during operation, inappropriate postural changes after operation, improper nursing and health education. Of the 8 dislocation cases, 2 were cured after reoperation and revision, 6 were cured through close reduction under anesthesia, and 7 were followed up for 1-5 years without relapse. ConclusionPreoperative assessment of the patients' soft tissue tension of affected hip and comorbid conditions, selection of proper design of prostheses and the components, removal of tissues possibly causing joint impact, correct placement of artificial prosthesis and components and instructing the patients for the correct movement mode of the affected hip after operation are all crucial for the prevention of postoperative hip dislocation.
ObjectiveTo examine the cause of failure of mitral valve repair. MethodWe retrospectively anal-yzed the clinical data of 89 consecutive patients with non-rheumatic mitral valve diseases who underwent reoperation for failure of mitral valve repair in our hospital from January 2009 through January 2016. There were 54 males and 35 females at age of 36.2±17.4 years. ResultsThere were 16 patients with reoperation of mitral valve repairs and 73 patients of mitral valve replacements. The failure reasons of initial mitral valve repair were technique-related in 63 patients (70.8%) and valve-related in 18 patients (20.2%). Technique-related causes of repair failure included leaflet suture dehiscence (20 patients, 22.5%), edge-to-edge procedure (11 patients, 12.4%), leaflet thickening or retraction (11 patients, 12.4%), ring dehiscence (8 patients, 9.0%), inappropriate annuloplasty (6 patients, 6.7%), incomplete repair (4 patients, 4.5%), and chordal elongation or rupture (3 patients, 3.4%). Median interval since previous repair was 4.0 (0.04-18.0) years for the technique-related failure group, and 9.7 (0.21-35.6) years for valve-related failure group (P < 0.05). ConclusionTechnique-related factors are main causes of repair failure, which include leaflet suture dehiscence, edge-to-edge procedure, and leaflet thickening or retraction. Reoperation for technique-related failure needs to be adopted early.
ObjectiveTo explore the causes and prevention measures of the cracking of skin tissue expander applied for ear deformity surgery. MethodsWe retrospectively analyzed the clinical data of the patients who underwent ear reconstruction surgery with skin tissue expander which cracked during water injection after surgery between January 2013 and March 2015. And then we analyzed the causes and summarized the preventive measures, such as strengthening health education, protective ear cap application, and correct water injection. ResultsWe collected a total of 149 patients including 153 deformity ears, and 151 skin tissue expanders were used. Skin tissue expander cracking occurred in 7 ears during water injection after surgery with an incidence of 4.64%. Among the seven cases, 5 cases of cracking occurred in the late water injection period when the skin flap size was almost close to expectations; these 5 patients underwent stage-two surgery after the expanders were taken out, and the results were satisfactory. The other 2 ears had expander cracking in the early water injection period, so we took out the skin tissue expander and implanted it again, and the second phase surgery was also satisfactory. The third-stage surgery for the seven cases was all successful. After the third-stage surgery, all patients were followed up for 3 to 6 months, and the outcomes were satisfying without any complications. ConclusionTo reduce or avoid skin tissue expander cracking, we should master strict terms of water injection and take effective health education and preventive measures.
Objective To explore the causes and solutions of dissatisfied complaints about frame glasses wearing after medical optometry to improve service quality. Methods Patients with dissatisfied complaints about frame glasses wearing after medical optometry in West China Medical Center of Optometry Glasses between January 2013 and December 2014 were selected. Targeted re-examination and corresponding treatment was performed on them. The causes of their complaints were clustered and analyzed. Result There were 105 cases of complaints out of the 58 278 patients with frame glasses wearing after medical optometry, including complaints about wearing glasses uncomfortable in 58 cases (55.2%), mainly related to abnormal binocular vision, high myopia and progressive glasses lens fitting; quality of glasses in 23 cases (21.9%), in whom 16 were dissatisfied with the frame; quality of service in 10 cases (9.5%); glasses assembly / calibration in 7 cases (6.7%); and other dissatisfaction in 7 cases (6.7%). Conclusions In medical optometry, optometrists and sales staff should establish a good communication with patients according to individual differences, attach importance to the selection of right frame and lens in patients with high myopia or progressive piece of glasses, introduce the right wearing method of progressive piece of glasses, and enhance the follow-up service. For patients with obvious eye fatigue, it is needed to check the binocular visual function, if the visual fatigue is closely related to abnormal binocular visual function, special glasses fitting and functional training should be instructed to the patients.
