Objective To investigate the relationship between recurrent vulvovaginal candidiasis (RVVC) and personal behavior and life style.Method Seventy-two patients with RVVC and 72 normal healthy women were studied with questionnaire by case-control design.Results Analysis by univariate unconditional logistic regression showed that contraception (OR=0.266), frequently changing and washing one’s underpants (OR=0.378), vaginal douche (OR=1.881), sharing bath towel with others (OR=1.872), sharing underpants with others (OR=6.163) and cigarette smoking or passive smoking (OR=3.164) were significantly associated with RVVC at significance level of 0.05. Analysis by multivariate unconditional logistic regression showed that contraception (OR=0.219), frequency of sexual intercourse (OR=1.806), use of sanitary napkins without guaranteed quality (OR=1.844), self-vaignial douche (OR=1.911) and cigarette smoking or passive smoking (OR=2.875) were associated with RVVC at significance level of 0.15.Conclusions Poor personal hygiene and unhealthy life style were important factors attributed to RVVC. It is suggested to promote correct personal hygienic behavior and healthy life-style in women by health education in order to reduce RVVC.

Objective To explore the feasibility to diagnose ureterolithiasis by 16-multidetector spiral computed tomography (16-MDCT) at different low doses based on body mass index (BMI).Methods A total of one hundred patients from 2009 Sep to 2010 Feb suspected of ureterolithiasis were randomly divided into 2 equal groups undergoing 16-MDCT at standard-dose (120 kV, 240 mA) or lowdose (120, 80, and 50 mA, respectively) based on the body mass index (BMI).Taking the clinical diagnosis as the standard, the sensitivity level, specificity level, and positive predictive value of these groups were compared.Results The dose length product ( DLP ) of the low-dose CT group and the average CT dose index (CTDIvol ) were 18.95 and 6.65 mGy, respectively.There was significant difference between the two groups ( t = 31.78, P ＜ 0.01 ).The sensitivity level, specificity level, and positive predictive value of the low-dose group were 97.1% , 94.0% , and 94.3% , respectively, all not significantly different from those of the standard-dose groups (97.3% , 96.0% , and 97.3% , respectively,P ＞0.05).Conclusions It is feasible to diagnose ureterolithiasis by low-dose 16-MDCT based on BMI with the obtained image quality meeting the clinical diagnostic requirements.

Purpose/Significance To investigate the effectiveness of experiential teaching in perinatal healthcare management contin-uing education.Method/Process The perinatal healthcare team of Peking Union Medical College Hospital holds a four-day experiential learning program for 30 maternity-related medical staffs from China.Through the self-administered experiential teaching questionnaire(ETQ)and satisfaction questionnaire,the researchers analyze the participants'post-teaching skill acquisition,clinical application abil-ity and educational needs,as well as their satisfaction with course content,course duration,teaching design,classroom atmosphere,and teaching format,which are quantified with Likert scale.Result/Conclusion The experiential teaching mode shows good teaching effects in perinatal healthcare management continuing education,and has higher application value.In the future,the researchers should combine it with theoretical teaching and carry out more comprehensive and structured periodic learning classes throughout the country,so as to im-prove both the theoretical foundation and practical ability of healthcare workers for better healthcare services for pregnant women.
