Objective To evaluate the clinical appliance and significance of the technique of anorectal manometry. Methdos Different ways of anorectal manometry, domain of its appliance and its clinical appliance was summarized and reviewed. Results The technique of anorectal manometry not only has important value on the study of analrectal pathology and physiology, but also can be associated with other examinations to manage biofeedback therapy, diagnose all kinds of anorectal diseases and evaluate anorectal function. Conclusion Anorectal manometry is a safe, simple, harmless and impersonal examination technique. It is necessary in the examination of analrectal function, in the diagnosis and treatment of anolrectal diseases.
Objective To diversify the methods of human physiology teaching for medical students at Chang Gung University College of Medicine. Methods We divided the grades of semester evaluation for physiology into two parts: 70% for lecture-examinations, 30% for non-examination-associated learning model including oral presentation of a scientific paper (conference), problem-based learning (PBL) performance, and quizzes. Results By a questionnaire survey at the end of the semester, we found that students were willing to spend time preparing non-examination-associated learning model; and from their own evaluations, the effectiveness of non-examination-associated learning was comparable to lecture-examination methods. Conclusion We conclude that from this analysis of students’ learning attitude and actual time (in hours per week) spent in each learning models, non-examination-associated learning model is well accepted and appeares to be as effective as traditional examination-forced study.
Objective To explore the method of teach evidence-based medicine (EBM) for medical postgraduates through by analyzing EBM examination paper in 2003 and 2004.Methods Participants: Two hundred and twenty one second year medical postgraduates who selected EBM course in 2003 and 2004 were included. Examination: Two parts were included in 2003: A test of EBM knowledge with open book in class (80 points) and an evidence-based case report on five steps of evidence-based practice (15 points). In 2004, the students were required to present an evidence-based case report on five steps of evidence-based practice (80 points). Evaluation: Based on the principle of EBM and five steps of evidence-based practice, we worked out an unified criteria and independently evaluated all examination papers. All scores were converted into the hundred percentage point system. Results The distribution of the mean score in 2003 was nearly normal and in 2004 was skewed. The mean score (standard deviation) was 75.5 (6.5) points in 2003 and 69.8(11.8) points in 2004. The passing grade rate was 97.4% in 2003 and 95.3% in 2004. The comparison between basic knowledge of EBM and skills of EBM in 2003: The mean score (standard deviation) was 62 (6.4) in basic knowledge of EBM and 55.1(16.7) in skills of EBM. Feedback from students: About 80% students thought EBM course was very helpful; about 95% students mostly achieved their expected goals.Conclusions We should teach and lead students to the method of self-directed learning and help them develop skills to use EBM in clinical practice.
ObjectiveTo explore the application of positron emission computed tomography (PET)/computed tomography (CT) in health physical examination. MethodsWe retrospectively analyzed the data of 1 515 people who underwent physical examination in West China Hospital of Sichuan University from January 2012 to November 2013. Demographic data and results of PET/CT scan were analyzed statistically. Follow-up was performed. ResultsTwenty-one cases of malignant tumors were found by PET/CT, including 7 cases of lung cancer, 5 of colon cancer (3 of sigmoid colon cancer, 1 of ascending colon cancer, and 1 of transverse colon cancer), 4 of thyroid carcinoma, 2 of nasopharyngeal carcinoma, 1 of prostate cancer, 1 of ovarian cancer, and 1 of other kind of cancer. All of them were confirmed after further examinations. ConclusionPET/CT has a positive significance in physical examination for some specific population.
There are many types of fundus diseases and their causes are complex. They can be caused by metabolic factors or inflammatory factors. Fundus examination and imaging examination tools are the main methods for diagnosing fundus diseases. However, in terms of determining the cause and early diagnosis, if the intraocular fluid detection technology can be reasonably combined, the advantages will be greater. Intraocular fluid is the general term for fluid in the eyeball, including aqueous humor, vitreous humor, etc. The molecular components that can be tested include DNA, RNA, antigens, antibodies, and cytokines. With the advancement of molecular testing technology and equipment, intraocular fluid testing as an evidence-based method has gradually been incorporated into the consensus and guidelines of more fundus disease experts, and is mainly used for infectious fundus diseases and camouflage syndromes. Reasonable use of intraocular fluid testing can help improve the personalized diagnosis and treatment of fundus diseases and reduce unnecessary drug overuse. However, it is worth noting that intraocular fluid detection is only one of many tools and cannot replace other examinations and clinical experience. Excessive intraocular fluid testing not only increases the risk of clinical infections because of invasiveness, but also increases the burden on patients.
