Objective: To analyze the correlated risk factors of endodontic interappointment emergencies(EIAE) and the intervention effect of microwave endodontic sterilization. Methods: 163 patients with chronic periodontitis, pulpitis or dental pulp necrosis (without acute inflammation) were involved in the study. All the patients were distributed into microwave group (n=80) and control group (n=83) randomly. Unitarily finished endodontic therapy was conduced in microwave group after the microwave endodontic sterilization. Same endodontic therapy was applied in control group but without microwave endodontic sterilization. Risk factors of EIAE were investigated by releasing questionnaire. Logistic regression analysis was used to analyze the data. Results: Incidences of EIAE were related to age, gender, the position of the tooth, with or without fistula, filling condition and with or without microwave endodontic sterilization. The risk factors of EIAE of ultra-filling, posterior inferior tooth,the age older than 45 years and the female was 3.32,3.49, 5.87 and 3.71 respectively (P

Objective To determine the prevalence and risk factors for latex glove allergy in clini-cal nurses. Methods A serf-administered questionnaire was used to collect the information about latex glove-related allergy among clinical nursing staff in 4 general hospitals in Zhanjiang, and the risk factors were calculated with logistic regression analysis. Results Latex glove-related symptoms were reported in 16.9% of 1469 nurses. Age, employment seniority, and positive rate of personal and family history of ana-phylaetie diseases in sensitized nurses were superior to those in unsensitized ones. The positive personal and family history of hypersensitivity diseases, allergy to drugs or other materials, and working time in a room were high risk factors for the development of latex glove allergy, but the average number of gloves used in a working day was the protective factor. Conclusions Clinical nurses belong to high risk latex sensitization population, and the main risk factor is the atopie subjects.
