Factors associated with mortality and functional disability after hip fracture: an inception cohort study

Hip fracture results in excess mortality and functional disability. This study sought to identify predictors of mortality and limited functional ability 1 year after hip fracture. We conducted a 1-year follow-up of a prospective population-based inception cohort of 218 hip fracture patients who had been consecutively admitted and discharged from hospital during the previous year. Mortality was observed to be independently associated with poor mental status (relative risk [RR]=6.96; 95% confidence interval [95% CI], 1.73–28.00), prefracture limited functional ability (RR=4.35; 95% CI, 1.32–14.36), institutionalized disposition at discharge (RR=2.92; 95% CI, 1.02–8.38), and male gender (RR=2.44; 95% CI, 1.01–5.93). Independent predictors of limited functional ability were prefracture functional disability (RR=34.14; 95% CI, 3.13–372.33), poor mental status (RR=9.71; 95% CI, 1.57–59.82), age >80 years (RR=4.03; 95% CI, 1.48–11.00), and female gender (RR=3.57; 95% CI, 0.08–0.98). On discharge, special attention and care should thus be given to all patients displaying any of the above predictive factors.     

Discontinuation of Living Donor Liver Transplantation for PSC Due to Histological Abnormalities in Intraoperative Donor Liver Biopsy

Liver transplantation is the only curative treatment known to date for end-stage liver disease occurring as a result of primary sclerosing cholangitis (PSC). Here, we report a case in which living donor liver transplantation (LDLT) for PSC was cancelled because of histological abnormalities in intraoperative biopsy of the donor liver. The donor was the mother of the recipient, and her preoperative evaluation revealed no abnormalities. In the donor operation, the donor liver biopsy revealed expansion of the portal zone with lymphocytic infiltration and dense concentric fibrosis developed around a bile duct. These histological findings were identical to those of early-stage PSC; therefore, the LDLT was called off. The experience in this case suggests that preoperative liver biopsy may be useful to exclude first-degree relative donors with potential PSC prior to LDLT for PSC.     

TSS and traditional surgery in hip and knee replacement

Surgery passes through a continuous evolution, thanks to the introduction of new technologies and techniques. Tissue-sparing surgery is a concept introduced in the last years to address prosthetic surgery to a more conservative fashion. We discuss the TSS decalogue with a critical eye, pointing out how traditional surgery is evolving in accordance with TSS statements.

老年新鲜股骨颈骨折治疗方法探讨

目的 探讨老年新鲜股骨颈骨折的术式选择。方法 回顾性分析217例60岁以上新鲜股骨颈骨折，分别采用单钉固定(46例)、多针固定(37例)、AO空心钉固定(79例)、人工髋关节置换(55例)4种方法，对比骨折愈合率、股骨头坏死率、髋关节功能恢复优良率。结果 内固定组骨折愈合率83．3％(140／162)，股骨头坏死率19．1％(31／162)，髋关节功能优良率75．9％(123／162)。其中空心钉组骨折愈合率94．9％(75／79)，股骨头坏死率6．3％(5／79)，髋关节功能优良率91.1％(72／79)。人工关节组髋关节功能优良率89．1％(49／55)。结论 内固定手术对老年新鲜股骨颈骨折有意义，AO空心钉固定操作简单，骨折愈合率高，可作首选内固定。人工髋关节置换应严格掌握适应证。     

改良显微小梁切除术治疗葡萄膜炎继发性青光眼

Objective To investigate the effect of trabeculectomy combined with segmental iridectomy, mitomycin C (MMC) and viscoelastic agents usage on the treatment of glaucoma secondary in uveitis. Methods According to the age, degree of inflammation and the condition of Tenon capsule of patients, differ-ent concentration of MMC (0.25-0.33 mg/ml) was used during the operation, with separation of the anterior and posterior synechia, resection of pupillary organization membrane using viscoelastic agents. Segmental iridec-tomy and releasable sutures were also performed on the patients. The visual acuity of preoperation and postoper-ation, intraocular pressure, inflammation and the complication were record. Results Forty-two eyes of 38 cases with glaucoma secondary in uveitis were studied, the mean follow-up time was (12.01±3.56) months. The postoperative visual acuity improved in 14 eyes, didn't change in 28 eyes. The postoperative inflammation of anterior chamber disappeared in 35 eyes, relieved in 7 eyes. And the average postoperative intraocular pres-sure (15.20± 4.64) mmHg was significantly lower than the preoperative intraocular pressure (38.37±12.93) mmHg (t = 8.255, P = 0.000). The total success rate was 92.9%. There were no severe complication. Conclusion Trabeculeetomy combined with MMC, viscoelastic agents usage, separation of anterior and poste-rior syneehia, segmental iridectomy and releasable suture could increase the success rate of operation on pa tients with glaucoma secondary in uveitis, decrease the complication and inflammation reaction of operation, and the recurrence of uveitis.     

检测MEGX判定肝储备功能评估手术风险

目的 通过检测肝癌病人利多卡因代谢产物(MEGX)的量,判定肝储备功能,评估手术风险.方法 对准备手术治疗的肝癌病人术前静注利多卡因1 mg/kg体重,15 min后抽血,用HPLC法检测MEGX,与常用肝生化检查、Child-Pugh分级方法比较.结果 根据MEGX检测结果将55例准备手术的肝癌病人分成手术耐受组和手术非耐受组.耐受组均经受了手术打击,无术后严重肝衰发生,而非耐受组有两例手术治疗,术后均出现了严重的肝衰,其中一例死亡.结论 MEGX试验较Child-Pubh分级方法更能准确判定肝储备功能,对评估手术风险有较高的特异性.
