ABSTRACT
Objective To explore the necessity of setting up the course on clinical healthcare-associated infection (HAI) and effectiveness of the case-based teaching method in medical higher education.Methods 198 students who underwent internship in a hospital between July 2015 and July 2016 were selected,according to whether they selected clinical HAI coures,they were divided into course selective group(n =107,adopted case-based teaching method) and unselective group(n =91),questionnaire survey on the knowledge and attitude of HAI was carried out.Results The average score on HAI in selective group was higher than that of unselective group([85.3 ± 1.6] vs [58.3 ± 1.8],t =111.72,P＜0.01).Before and after conducted case-based teaching method,21.49％ and 47.66％ of students actively studied respectively,difference was significant (x2 =16.195,P＜0.01).Conclusion It is necessary to carry out a systematic course on HAI,case-based teaching method can improve the learning enthusiasm of students.
ABSTRACT
<p><b>PURPOSE</b>Traumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%-5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries.</p><p><b>METHODS</b>In this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were retrospectively reviewed for preoperative vision, visual evoked potential (VEP) scan, surgical approach, postoperative visual acuity, complications, and follow-up results.</p><p><b>RESULTS</b>All these patients received endoscopic decompression of the optic canal. At the 3-month follow- up, the visual acuity improvement rate of the 11 patients was 45.5%. The vision acuity of 2 cases improved from hand movement to 0.08 and 0.3 after operation. Another patient's vision acuity returned to 0.05 compared to light sensation preoperatively. Two cases had finger counting before surgery but they had a vision acuity of 0.4 and light sensation respectively after surgery. However, the other 6 cases' vision did not improve after surgery.</p><p><b>CONCLUSION</b>Endoscopic decompression of the optic canal is an effective way to cure TON. VEP could be used as an important reference for preoperative and prognosis evaluation. Operative time after trauma is only a relative condition that may affect the therapeutic effect of optic canal decompression. Poor results of this procedure may be related to the severity of the optic nerve injury.</p>
