OBJECTIVE: To examine the value of self-treatment for Posterior canal benign paroxysmal positional vertigo (PC-BPPV). The treatment effect was compared between patients treated with modified Epley in outpatient clinic combined with self treatment at home and patients treated by modified Epley alone. METHOD: A randomized controlled trial were carried out in the Department of Otolaryngology Head and Neck Surgery, the Affiliated Sixth People's Hospital of Shanghai Jiao Tong University from December 2012 to May 2013. 147 out of 150 patients with unilateral idiopathic BPPV-PSC were enrolled in follow-up. Among which, 73 patients were allocated in modified Epley-alone group and 74 were allocated in slef-treatment group. RESULT: The success rate was 53.4% in modified Epley-alone group vs 83.8% in self-treatment group (P < 0.01) after 1 week treatment. In the modified Epley-alone group,the success rate of hand repositioning group and chair-assisted repositioning group was 45.9% vs 61.1% (P > 0.05), the risk rate was 0.752, 95% CI (0.486 - 1.163). In the self-treatment group, the success rate of hand repositioning group and chair-assisted repositioning group was 87.5% vs 81.0% (P > 0.05), the risk rate was 1.081, 95% CI (0.888-1.316). Incidence rate of serious complications was 0% in the modified Epley-alone group and 1.3% in the self-treatment group (P > 0.05). CONCLUSION Complementary self-treatment with modified Epley maneuver treated PC-BPPV sooner and more effectively, Compared with modified Epley maneuver alone. And its incidence rate of serious complications didn't increase. Chair-assisted repositioning showed better result than hand repositioning alone, and self-treatment at home can reduce the effect of the gap. We found that complementary self-treatment with modified Epley maneuver had more benefits for patients with PC-BPPV.

Objective To investigate the training process of clinical practice ability in medical undergraduates in the context of tutorial system,as well as new clinical training models and evaluation methods.Methods A total of 40 medical undergraduates who entered the stage of clinical practice were randomly divided into tutorial group and control group,with 20 undergraduates in each group.A diversified evaluation system was used to perform a comprehensive evaluation of clinical practice ability of medical undergraduates at different stages,with a combination of professional theory examination,Mini-Clinical Evaluation Exercise,Direct Observation of Procedural Skills,and clinical case report.All the data were analyzed by SPSS 23.0,t test was used for statistical analysis.Results Compared with the control group after the internship ended,the tutorial group had significantly higher scores of clinical professional theory (86.24 ± 2.93),clinical practice ability (7.53 ± 0.48),clinical operation skills (4.35 ± 0.47),and clinical thinking ability (6.31 ± 0.52) (all P＜0.05).Conclusion The application of the tutorial training mode during the internship of medical undergraduates can improve their comprehensive qualities such as professional quality,medical theory,and practical skills.The diversified evaluation system can evaluate the teaching effect and reflect the cultivation of comprehensive quality among students.
