Background:
Most proximal femoral fractures are successfully treated with internal fixation but a failed surgery can be very distressing for the patient due to pain and disability. For the treating surgeon it can be a challenge to perform salvage operations. The purpose of this study was to evaluate the short-term functional outcome and complications of total hip arthroplasty (THA) following failed fixation of proximal hip fracture.Materials and Methods:
In a retrospective study, 21 hips in 20 patients (13 females and seven males) with complications of operated hip fractures as indicated by either established nonunion or fracture collapse with hardware failure were analysed. Mean age of the patients was 62 years (range 38 years to 85 years). Nine patients were treated for femoral neck fracture, 10 for intertrochanteric (I/T) fracture and two for subtrochanteric (S/T) fracture of the hip. Uncemented THA was done in 11 cases, cemented THA in eight hip joints and hybrid THA in two patients.Results:
The average duration of follow-up was four years (2-13 years). The mean duration of surgery was 125 min and blood loss was 1300 ml. There were three dislocations postoperatively. Two were managed conservatively and one was operated. There was one superficial infection and one deep infection. Only one patient required a walker while four required walking stick for ambulation. The mean Harris Hip score increased from 32 preoperatively to 79 postoperatively at one year interval.Conclusion:
Total hip arthroplasty is an effective salvage procedure after failed osteosynthesis of hip fractures. Most patients have good pain relief and functional improvements inspite of technical difficulties and high complication rates than primary arthroplasty. 相似文献102.
Inhibition of breast tumor growth and angiogenesis by a medicinal herb: Ocimum gratissimum 总被引:2,自引:0,他引:2

Ocimum sp. is a traditionally used medicinal herb, which shows anti-oxidant, anti-carcinogenic, radio-protective and free radical scavenging properties. So far no detailed studies have been reported on its effects on human cancers. Thus, we analyzed its effects on human breast cancer utilizing in vitro and in vivo methodologies. Aqueous extracts were prepared from the mature leaves of Ocimum gratissimum (OG) cultivated devoid of pesticides. Tumor progression and angiogenesis related processes like chemotaxis, proliferation, apoptosis, 3D growth and morphogenesis, angiogenesis and tumor growth were studied in the presence or absence of the extract, and in some experiments a comparison was made with purified commercially available eugenol, apigenin and ursolic acid. Aqueous OG leaf extract inhibits proliferation, migration, anchorage independent growth, 3D growth and morphogenesis and induction of COX-2 protein in breast cancer cells. A comparative analysis with eugenol, apigenin and ursolic acid showed that the inhibitory effects on chemotaxis and 3D morphogenesis of breast cancer cells were specific to OG extract. In addition, OG extracts reduced tumor size and neoangiogenesis in a MCF10 DCIS.com xenograft model of human DCIS. This is the first detailed report showing that OG leaf extract may be of value as a breast cancer preventive and therapeutic agent and might be considered as additional additive in the arsenal of components aimed at combating breast cancer progression and metastasis. 相似文献

In the present study, we have synthesized chalcone and semicarbazide-linked chalonyl derivatives and the titled compounds
confirmed by MS, IR, and 1H NMR techniques. The anticonvulsant activity was determined by maximal electroshock (MES) induced seizure method. A majority
of the compounds exhibited significant anticonvulsant activity after intraperitoneal administration. The results show the
importance of hydrogen bonding for activity. In the present study 5e, 5h, 5i, 6e, 6h, and 6i emerged as the most active molecules, showed significant anticonvulsant of activity. 相似文献

Proton pump inhibitors (PPIs) have been known to cause bradycardia. We evaluated the effect of three PPIs, i.e. omeprazole,
rabeprazole and pantoprazole on the heart rate of frog. The in situ frog heart preparation was set up. Heart rate and amplitude of contraction were studied following administration of different
doses of the three PPIs. Statistical analysis was done by using Graphpad statistical software system. After 1 mg of omeprazole
and rabeprazole, and 2 mg pantoprazole, the heart rate was similar as compared to baseline (p >0.05). After 2 mg of omeprazole
and rabeprazole, and 4 mg pantoprazole, the reduction in heart rate was significant (p <0.05). In addition, pantoprazole caused
negative ionotropic effect. The three PPIs showed a dose-dependent negative chronotropic effect in the frog heart prepration. 相似文献

Abdominal colon and rectal operations in the elderly 总被引:7,自引:5,他引:2
William E. Wise Jr. M.D. Anantha Padmanabhan M.D. Deborah M. Meesig M.D. Mark W. Arnold M.D. Pedro S. Aguilar M.D. William R. C. Stewart M.D. 《Diseases of the colon and rectum》1991,34(11):959-963
Sixty-seven abdominal operations for colon and rectal disorders were performed on 56 patients 80 years of age or older from January 1, 1984 to June 30, 1989. Nine patients required multiple operations. Sixty-two procedures (92 percent) were performed on patients in their ninth decade; two operations were performed on patients 95 years of age or older. Forty-five patients (80 percent) were operated upon for carcinoma. Operations included segmental colectomy (33 patients), low anterior resection (12 patients), total abdominal colectomy (3 patients) and abdominoperineal resection (2 patients). Forty patients were classified as ASA Class III; the majority were monitored in the surgical intensive care unit for a mean of 2.84 days. Thirty patients were monitored with arterial catheters and 21 with central invasive monitoring. Operative mortality was 7 percent (4 patients). Two patients died from diffuse carcinomatosis; one patient had a fatal myocardial infarction. The final death occurred from multisystem organ failure following anastomotic dehiscence. Twenty-seven operations were performed without postoperative complications; 18 operations were followed by a single minor complication. The average hospital stay was 18.96 days. All patients were admitted from home. Thirty-three returned home postoperatively; 16 were discharged to an extended care facility. In conclusion, elderly patients with colon and rectal disorders can be operated upon with acceptable morbidity and mortality. Age alone should not interdict surgical therapy. 相似文献
