Patients seeking primary care often have upper respiratory symptoms caused by viral infection. Most patients are diagnosed based on medical interviews and physical examinations ; however, such diagnoses are often based on experience, and education for younger physicians regarding such patients is often insufficient. This review addresses evidence related to history and physical findings of cough, sore throat, and nasal discharge. We reviewed differential diagnosis of cough, as well as select diagnosis, including the common cold, acute bacterial sinusitis, Bordetella pertussis infection, and gastroesophageal reflux disease. Sore throat is similarly reviewed through differential diagnosis and select diagnosis, including Streptococcal (group A) infection, infectious mononucleosis, and Mycoplasma and Chlamydia. Nasal discharge is reviewed in terms of differential diagnosis and allergic rhinitis. Many histories or physical findings of upper respiratory symptoms are not supported by evidence, and further study is warranted.

The use of clinical databases is becoming increasingly common. We introduce a real-time clinical database named SINAP (Stroke Improvement National Audit Programme) which was originally deployed as a research database. We addressed its educational application in a hospital.
We visited a leading stroke ward in the UK, which had a hyper acute stroke facility, and investigated the current operation and application of the SINAP database. The ward contained a hyper acute stroke unit with 12 beds and a 20-bed stroke unit. About 400 patients were treated in three months (January-March, 2011). The SINAP database was used not only for research reports but also for conferences concerning patient management, and it facilitated learning by clinical staff at the hospital.
Databases which record clinical data relevant to performance and quality are an effective tool for improving the quality of treatment and care, as well as for training staff in clinical practice. Considering the wide-spread use of information technologies in primary care, such utilization of clinical data seems appropriate and effective to improve the quality of practice.

Clinical clerkships have been gradually introduced in medical schools in Japan. Because all students do not rotate through the same departments, the satisfaction of medical students differs among the departments, although the underlying reasons for such differences are unclear. To investigate the factors associated with student satisfaction with clinical clerkships, we performed a questionnaire survey.1) Questionnaires were distributed to 99 fifth-year medical students at Kyoto University Medical School. The questionnaire consisted of Likert-type 5-level scales of satisfaction, clinical clerkship assignments, and the attitudes of clerkship supervisors and other attending staff. Eighty-nine students responded.2) The independent factors for students' satisfaction were the attitude of attending staff (beta coefficient, 0.34), the attitude of the clerkship supervisor (0.30), and the frequency of physical examinations (0.09).3) Twenty-two of the 34 students who expressed the lowest level of satisfaction (level 1) reported that "the attending staff rarely had contact with students."4) Factors not associated with satisfaction were: whether the rotation was in internal medicine or surgery; whether the rotation was in a community hospital or a university hospital, and the department.5) These results suggest that medical students are satisfied with a clerkship if they perform frequent physical examinations and if the attending staff have an enthusiastic attitude.

BACKGROUND : Norm-referenced equations to predict the 6-minute walk distance (6MWD) in healthy Japanese subjects have not been established. The current study aimed to determine the reference values for 6MWD in healthy Japanese adults.
METHODS : Ninety-seven healthy Japanese men and women aged 40-79 years were recruited from Kyoto city using posters and flyers. Measurements of 6MWD were performed twice on an indoor 30 m track with 20 minutes rest between the two tests. Before performing the tests, age, gender, height, body weight, waist circumference, a questionnaire for health status, spirometry, and a 12-lead electrocardiogram were recorded. The 6MWD was measured following guidelines published in 2002 by the American Thoracic Society.
RESULTS : The mean age of the study subjects was 57.0±9.4, and 63 of the 97 subjects were female. The mean 6MWD for all subjects was 672±83 m, with a range of 483-903 m. The 6MWD is significantly correlated with age, height, waist circumference, forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁). A multiple linear model showed age, waist circumference, and FVC were significantly associated with 6MWD and the model explained 35% of the variability in 6MWD. When FVC was replaced by height, the regression model also explained 32% of the variation. The measured 6MWD of Japanese subjects was similar to the predicted 6MWD using the equations derived from Caucasian subjects.
CONCLUSIONS : The 6MWD was affected to a substantial degree by age, waist circumference, height, and FVC in healthy Japanese adults.

Objective:It is well known that the use of benzodiazepines is associated with falling in elderly people, but there have been few researches focused on changes in the dose of benzodiazepines and falls. If the association between changes in the dose of benzodiazepines and falling becomes clear, we may take an action to prevent falling.In this study, we investigated the association between changes in the dose of benzodiazepines and falling among elderly inpatients in an acute-care hospital.
Design:Falling generally results from an interaction of multiple and diverse risk factors and situations, and medication history of each subject must be considered in this study. We conducted a case-crossover study in which a case was used as his/her own control at different time periods. Therefore covariates that were not time-dependent were automatically adjusted in this study.
Methods:Subjects were patients who had falling at one hospital between April 1, 2008 and November 30, 2009. Data were collected from incident report forms and medical records. Odds ratio for changes in the dose of benzodiazepines were calculated using conditional logistic regression analyses.
Results:A total of 422 falling by elderly people were eligible for this study. The odds ratio for increased amounts of benzodiazepines was 2.02(95% Confidence Interval(CI):1.15, 3.56). On the other hand, the odds ratio for decreased amounts of benzodiazepines was 1.11(95%CI:0.63,1.97).
Conclusion:There was an association between increased amounts of benzodiazepines and falling. Hence, it is considered meaningful to pay attention to falling when amounts of benzodiazepines are increased to prevent falling in hospitals.

1) We compiled lists of accredited training hospitals for postgraduate education from the matching program list and of hospitals that employ board-certified specialists in emergency medicine.We then evaluated the number of training hospitals that employ board-certified specialists.
2) There are 1072 accredited hospitals for postgraduate education. However, only 546 (50.8%) of these hospitals employ board-certified specialists in emergency medicine.
3) Accredited training hospitals with emergency-medicine specialists are prevalent in Okinawa, Tokushima, and Kagawa prefectures.However, the prevalence of these hospitals is surprisingly low in metropolitan areas.

A 60-year-old male was diagnosed as having sarcoidosis four months previously because of bilateral hilar lymphadenopathy seen on a chest X-ray, uveitis, and elevation of serum angiotensin converting enzyme. In summer, the patient suffered from hypercalcemia, hypercalciuria, and renal dysfunction. Renal biopsy showed interstitial nephritis with gallium scintigraphy demonstrating high uptake in the bilateral hilum, eyes, and kidneys. Corticosteroid treatment was effective in remarkably improving the renal disorder and radiographic abnormalities.
The calcium metabolic abnormalities and the granulomatous interstitial nephritis showed a marked response to corticosteroid therapy, so that immediate administration of corticosteroid may be justified even in cases without histological evidences. Gallium scintigraphy is suggested to be useful in noninvasive examination in acute stage of sarcoidosis.
