ABSTRACT
Objective To study the survival status of very elderly patients with intertrochanteric fracture admitted in hospital and its risk factors.Methods Clinical data of 54 patients with intertrochanteric fracture aged 90 years and over admitted in hospital from Jan.2006 to Dec.2013 were retrospectively analyzed.5 patients were lost to follow-up.The survival status of patients was analyzed.Results Patients were followed up until January 2015.The period of follow-up ranged from 85 months to 0.2 months,with an average follow-up of 33.3 months.17 cases were survived.Harris scores were(61.2 ± 10.6).The overall 1-,3-,5-year survival rates were(0.88 ± 0.05),(0.35 ±0.08),(0.18 ± 0.08),respectively.The mean and median survival times were (33.3 ± 4.6) months and(25.0±5.4) months.Cox proportional hazard regression model showed that American Society of Anaesthesiologists(ASA) score,operation time and the number of comorbidities were the risk factors for the survival time of very elderly patients with intertrochanteric fracture (all P ＜0.05).Conclusions Compared with conservative treatment,surgical treatment can increase the survival time of the elderly patients with intertrochanteric fracture.ASA score,operation time and the number of comorbidities may be the risk factors for the survival time of very elderly patients with intertrochanteric fracture.
ABSTRACT
Objective To summarize and analyze the relationship between exposure to rabies and its prevalence in Jurong City from 2003 to 2007,and discuss further the possible solutions to it.Methods The data of people vaccinated after being biten by animals were collected,manipulatd,and analyzed,with their illness records dealt with accordingly from 2003 to 2007 in Jurong City.Results Not a single one of 21 596 cases was that of rabies with proper treatment in the last 5 years.The sex ratio was 1.47∶1.The highest probability of exposure was the preschoolers under the age of 10.The disease occurred throughout the year,with the peak in July and September.Those biten by dogs accounted for 86.85% of the exposure to rabies,and among them,people biten by domesticated animals were in the majority.Wounds by the domesticated dogs reached 74.60%.Not a single case was treated properly among the 9 rabies cases reported in the same period.Conclusions Strengthening the management of domesticated dogs,publicizing the knowledge of rabies,treating the wound properly and thoroughly,innoculation with vaccine from the very beginning and administering rabies immune globulin are the effective ways to prevent rabies.
