Introduction
Dislocation following hip hemiarthroplasty (HHA), its incidence, predictors, treatment outcomes and mortality were investigated in a single centre series.Methods
The prospectively collected data on neck of femur fracture admissions compiled over 11 years were reviewed. Place of residence, place of fall, past medical history, intraoperative factors (grade of surgeon, delay in surgery, type of implant and operative time), postoperative complications and mortality were compared between patients who suffered a dislocation and those who did not. In the dislocation group, the mean number of dislocations, reduction method, type and fate of implant, and mortality were investigated.Results
Prospective data on 8,631 admissions were collected; 41% of these were managed with a HHA. The dislocation rate was 0.76%. A delay in surgery of >24 hours was associated with a fourfold increase in the dislocation risk. The majority (81%) of dislocations occurred in the first six weeks and closed manipulation was the definitive treatment in only 23% of the cases. The mortality rate was not increased following HHA dislocation.Conclusions
The delay in surgery was the most important predictor of HHA dislocation. Closed reduction was associated with a high failure rate. While an initial attempt at closed reduction for a first dislocation is recommended, for redislocators, we recommend early exploration/revision as an alternative to repeat manipulations. 相似文献433.

Hematopoietic SCT (HSCT) has become a curative therapeutic strategy for several malignant and nonmalignant diseases. We report the comprehensive results of the first 10 years of experience in HSCT from the two major BMT units in Lebanon: Makassed University Hospital and the American University of Beirut Medical Center. The median and the 5-year overall survival (OS) were 97 months and 58%, respectively, for the 84 patients who received allogeneic HSCT, and 60 months and 50%, respectively, for the 228 patients who received autologous BMT. The results for myeloablative allogeneic transplantation were as follows: AML (n=28, 5-year OS 58%, 5-year disease-free survival (DFS) 48%), CML (n=9, 5-year OS 66%, 5-year DFS 52%), ALL (n=13, 2-year OS 10%, 2-year DFS 10%), thalassemia (n=10, 5-year transfusion-free survival 67%). The results for autologous HSCT were as follows: diffuse large B-cell lymphoma (DLBCL) in relapse (n=37, 5-year OS 68%, 5-year progression-free survival (PFS) 65%), Hodgkin's lymphoma (n=55, 5-year OS 55%, 5-year PFS 36%), and first-line multiple myeloma (n=71, 5-year OS 53%, 5-year PFS 24%). For allogeneic transplanted patients, the cumulative TRM was 23% and the incidence of acute GVHD was 23%. For autografted patients, TRM was 2.6%. These results indicate that despite the relatively low socioeconomic status of the Lebanese population, both allogeneic and autologous HSCT are feasible with outcomes similar to developed countries. 相似文献

Acquired microvascular dysfunction in inflammatory bowel disease: Loss of nitric oxide-mediated vasodilation 总被引:7,自引:0,他引:7
BACKGROUND & AIMS: Inflammatory bowel disease (IBD; i.e., Crohn's disease, ulcerative colitis) is characterized by refractory inflammatory ulceration and damage to the intestine. Mechanisms underlying impaired healing are not defined. Because microvascular dysfunction resulting in diminished vasodilatory capacity and tissue hypoperfusion is associated with impaired wound healing, we hypothesized that microvascular dysfunction may also occur in chronic IBD. METHODS: Intact submucosal arterioles from control, involved, and uninvolved IBD specimens were assessed using in vitro videomicroscopy to assess endothelium-dependent vasodilation in response to acetylcholine (Ach) and fluorescence microscopy to detect oxyradicals. RESULTS: Normal microvessels dilated in a dose-dependent and endothelium-dependent manner to Ach (maximum, 82% +/- 2%; n = 34). Inhibition of nitric oxide synthase with N(G)-nitro-L-arginine methyl ester (L-NAME) reduced maximal dilation to 54% +/- 6% (P < 0.05, n = 7), and further reduction was observed after inhibiting cyclooxygenase (indomethacin; 23% +/- 10%, n = 6). Chronically inflamed IBD microvessels showed significantly reduced Ach-induced vasodilation (maximum, 15% +/- 2%; n = 33), with no effect of L-NAME. Indomethacin eliminated the remaining Ach-induced vasodilation, resulting in frank vasoconstriction (-54% +/- 9%, n = 6). Uninvolved IBD gut vessels and non-IBD inflammatory controls responded in a fashion similar to normal vessels. IBD-involved microvessels generated significantly higher levels of reactive oxygen species compared with control and uninvolved IBD vessels (P < 0.01). CONCLUSIONS: Human intestinal microvessels from chronically inflamed IBD show microvascular endothelial dysfunction, characterized by loss of NO-dependent dilation that may contribute to reduced perfusion, poor wound healing, and maintenance of chronic inflammation. 相似文献

A biomechanically altered rheumatic forefoot with a resulting shoe conflict and an impaired immune system due to underlying disease and medical treatment are often cause for infection. Often infected bursae perforate into the corresponding joints and may consequently lead to severe infectious states of the foot. The multiplicity of possible biomechanical adjustments makes it difficult to develop an undisputed concept. Conservative versus operative therapeutic options are possible and may be individually applied. It should be questioned, if the same general rules in septic joint surgery also apply to the rheumatoid forefoot. This retrospective clinical study will evaluate a concept for possible operative treatment of the infected rheumatoid forefoot in selected cases. Our conception advocates operative procedures on a patient adapted basis in order to prevent recurrent infections. Suggestions for operative procedures are given. 相似文献
