RESUMO
OBJECTIVES: We examined whether problem-based learning tutorials using patient-simulated videos showing daily life are more practical for clinical learning, compared with traditional paper-based problem-based learning, for the consideration rate of psychosocial issues and the recall rate for experienced learning. METHODS: Twenty-two groups with 120 fifth-year students were each assigned paper-based problem-based learning and video-based problem-based learning using patient-simulated videos. We compared target achievement rates in questionnaires using the Wilcoxon signed-rank test and discussion contents diversity using the Mann-Whitney U test. A follow-up survey used a chi-square test to measure students' recall of cases in three categories: video, paper, and non-experienced. RESULTS: Video-based problem-based learning displayed significantly higher achievement rates for imagining authentic patients (p=0.001), incorporating a comprehensive approach including psychosocial aspects (p<0.001), and satisfaction with sessions (p=0.001). No significant differences existed in the discussion contents diversity regarding the International Classification of Primary Care Second Edition codes and chapter types or in the rate of psychological codes. In a follow-up survey comparing video and paper groups to non-experienced groups, the rates were higher for video (χ2=24.319, p<0.001) and paper (χ2=11.134, p=0.001). Although the video rate tended to be higher than the paper rate, no significant difference was found between the two. CONCLUSIONS: Patient-simulated videos showing daily life facilitate imagining true patients and support a comprehensive approach that fosters better memory. The clinical patient-simulated video method is more practical and clinical problem-based tutorials can be implemented if we create patient-simulated videos for each symptom as teaching materials.

BACKGROUND: Telediagnosis (TD), which uses information and communications technology, has recently undergone rapid development. Since no studies have compared the diagnostic precision of TD to that of face-to-face diagnosis (FD), we examined and compared the diagnostic accuracy of these diagnostic approaches among general medicine outpatients. METHODS: Data of 97 patients (45 men and 52 women with a mean age of 52 years) who underwent initial examinations at a regional hospital were analyzed. Two fully trained general medicine physicians were selected from a group of three physicians to perform FD and TD. Levels of agreement (as κ coefficients) were determined between TD and FD diagnoses as well as between final diagnoses and TD and FD diagnoses. RESULTS: The κ coefficients were 0.75 for TD and FD and 0.81 for both, the final diagnoses and the TD and FD diagnoses, revealing a sufficiently high level of diagnostic agreement. CONCLUSIONS: TD can provide the same level of diagnostic accuracy as FD among general medicine outpatients for adults. The help of medical assistants and the utilization of physical examination devices might enable medical staff to provide TD care similar in quality to FD. TD could be a useful diagnostic tool when medical work force is limited (e.g., in remote areas, during natural disasters, and in at-home care).

Cases of sprue-like enteropathy associated with olmesartan have sporadically been encountered since it was first reported in 2012, and their most characteristic manifestation is severe diarrhea. We herein report the first case of sprue-like enteropathy manifesting as Wernicke-Korsakoff syndrome due to vitamin B1 malabsorption with only minimally increased bowel movements. When patients are receiving olmesartan and they complain of nonspecific chronic gastrointestinal symptoms, it is important to consider changing the drugs before any serious malabsorption syndrome develops.

INTRODUCTION: Anxiety and depressive symptoms are seen in patients with anxiety and mood disorders but are also common in those with organic disorders. However, since physical symptoms are predominant complaints from patients who visit nonpsychiatric outpatient clinics, anxiety and depressive symptoms are often unrecognized. It is important for physicians to be aware of these issues concurrent with the physical symptoms. We therefore examined whether a self-administered medical questionnaire could identify anxiety and depressive symptoms. PATIENTS AND METHODS: A total of 453 patients on their first visit to the Department of General Medicine, Chiba University Hospital, Chiba, Japan, participated in this study. They were asked to complete a medical questionnaire and the Hospital Anxiety and Depression Scale questionnaire before examination. Data on age, sex, number of complaints, symptom duration, and number of previous physicians were extracted from the medical questionnaire. These data were used as independent variables in logistic regression analysis to develop a predictive model for the presence of anxiety and depressive symptoms. RESULTS: Data from 358 (79.0%) patients were included in the analyses. Logistic regression analysis identified the following predictors: "three or more complaints" (odds ratio [OR] 2.39; 95% confidence interval [CI] 1.48-3.88) and "four or more previous physicians" (OR 1.72; 95% CI 1.10-2.69). In the predictive model for the presence of symptoms of anxiety and depression, the likelihood ratio was 2.40 (95% CI 1.33-4.34) in patients reporting both conditions and 1.35 (95% CI 1.04-1.77) in those reporting either condition. CONCLUSION: The presence of anxiety and depressive symptoms can be predicted from the items of a medical questionnaire in outpatients visiting a general medicine department of a university hospital. When patients report three or more complaints or four or more previous physicians on a medical questionnaire, physicians should consider the presence of anxiety or depression or both in differential diagnosis.
RESUMO
Objective Patients diagnosed with psoas abscess have a high mortality rate. The major cause of its poor prognosis is delayed treatment. Therefore, making a correct diagnosis rapidly is important. Both computed tomography (CT) and magnetic resonance imaging (MRI) are considered to be the gold standards as imaging modalities that have a high sensitivity for detecting psoas abscess. There have been few reports regarding the limitations of these methods, but psoas abscess in its early stage may go undetected by CT and MRI. Methods Detection of psoas abscess by CT and MRI was investigated in the present study through a retrospective review of 15 patients in whom psoas abscess was diagnosed during a course of ten years at our hospital. Results In all patients, psoas abscess was diagnosed by at least a plain CT, enhanced CT, and/or plain MRI. The interval between the onset of symptoms and diagnosis was 20.9±17.9 days (mean ± standard deviation). In three patients, repeat imaging identified a psoas abscess, whereas initial imaging failed to detect it. The overall sensitivity of plain CT, enhanced CT, and plain MRI for psoas abscess was 78%, 86%, and 88%, respectively. From six days after the onset of symptoms, the sensitivity of each modality was 100%, while the sensitivity from day one to five days was only 33%, 50%, and 50%, respectively. Conclusion Although CT and MRI are considered to be gold standard modalities for diagnosing psoas abscess, both methods can fail to notice this condition in its early stage.

OBJECTIVE: This study was performed to investigate the factors influencing the correlation between physician satisfaction and patient satisfaction in an outpatient setting. METHODS: New patients attending the General Medicine Outpatient Clinic of Chiba University Hospital and their physicians were enrolled. After the initial consultation, both the patients and the physicians completed an anonymous questionnaire. RESULTS: There were 875 patients (381 men and 494 women; mean age: 54 years) and 10 physicians (4 men and 6 women; mean experience: 6 years). The satisfaction of the patients and the physicians was not correlated (r=0.14, p<0.001). A logistic regression analysis revealed that the factors associated with greater physician satisfaction were "guidance/advice from senior colleagues" [odds ratio (OR)=2.03; 95% confidence interval (CI)=1.76-2.34] and "confidence in the diagnosis" (OR=1.52; 95%CI=1.37-1.69), while "a difficult patient" (OR=0.73; 95%CI=0.68-0.78) was associated with reduced satisfaction. The factors associated with greater patient satisfaction were "the doctor listened carefully" (OR=1.98; 95%CI=1.62-2.42) and "my diagnosis is correct" (OR=1.57; 95%CI=1.41-1.74). One item in the questionnaire for the physicians, "I diagnosed psychogenic illness" (OR=0.87; 95%CI=0.81-0.94), was associated with lower patient satisfaction. CONCLUSION: The satisfaction of the patients and the physicians was not correlated. If only the factors promoting the satisfaction of one party are targeted, the satisfaction of the other party will not increase. The satisfaction of the physicians may be increased by receiving advice from mentors and an improved diagnostic ability, while the patients wants a physician who listens carefully and makes the correct diagnosis.

PURPOSE: We hypothesized that even with appropriate clinical information, abnormal CT findings can still be missed if correct diagnostic predictions are not made. MATERIALS AND METHODS: Of 388 total students (97 5th-year medical students × 4), students who detected abnormalities without clinical information were eliminated. The remaining students (hereafter, subjects) obtained clinical information, made diagnostic predictions, and reevaluated images. The proportion of failures in detecting abnormalities was compared between the correct prediction group and the incorrect prediction group. In the correct prediction group, the relationship between failures of detection and the ranking of the correct diagnosis was also examined. RESULTS: A total of 341 subjects were assessed. The proportion of subjects who failed to detect abnormalities in the correct prediction group (47.7 %, 93/195) was significantly lower (P < 0.001) than in the incorrect prediction group (85.6 %, 125/146). In the correct prediction group, the proportion of subjects who failed to detect abnormalities was significantly lower (P = 0.004) when the correct diagnosis was ranked first (38.5 %, 42/109) compared with lower rankings (59.3 %, 51/86). CONCLUSION: Making appropriate diagnostic predictions and estimating the possibility of them based on clinical information is important to avoid missing abnormal CT findings.

The microbicidal activity of the myeloperoxidase (MPO)-hydrogen peroxide-halide system has been implicated as the most efficient, oxygen-dependent antimicrobial component of neutrophil host defense. Unexpectedly, individuals with MPO deficiency suffer few clinical consequences. In order to understand better the clinical impact of MPO deficiency, we surveyed several clinical hematology laboratories in Japan to assess the prevalence of MPO deficiency in the general population. MPO activity was determined by flow cytometry using the Technicon H series of automated systems. We identified 26 cases of complete MPO deficiency, prevalence 1 in 57,135, and 129 cases of partial deficiency, prevalence 1 in 17,501. The distribution of complete and partial deficiencies differed among the laboratories studied.
