Introduction: Primary care (PC) physicians often struggle with the local dialects of patients, especially when they work away from their hometowns.Method: We conducted a questionnaire survey of PC physicians in the Hokushinetsu region, the northcentral part of Honshu island of Japan, to understand how doctors recognize and deal with local dialects in their daily clinical practice.We also analyzed their comments qualitatively using the Steps for Coding and Theorization (SCAT) method.Results: Thirty-one physicians (21 men and 10 women) completed the questionnaire. Of the total, 71% of respondents worked away from their hometowns.Moreover, 81.8% of these respondents stated they had difficulties understanding the dialect spoken in the region of their workplaces and 36.3% misunderstood the meanings of the dialect spoken by their local patients as a result. Respondents often heard "ui" or "tekinai" as the chief complaints of local patients, and interpreted these words as physical symptoms such as fatigue, dyspnea, and abdominal distension. SCAT analysis suggested that these words can have different meanings depending on the context. PC physicians translate them into medical terms using paraphrasing techniques based on each patient's medical history. Furthermore, PC physicians use dialects according to their relationship with the patient.Conclusion: Understanding the characteristics of these dialects and using them appropriately may improve the doctor-patient relationship.

Objective: Atopic dermatitis (AD) is one of the known risk factors for Staphylococcus aureus infection. The authors report the case of a patient with cervical spondylosis and AD who developed delayed surgical site infection after posterior cervical instrumented surgery.Patient: A 39-year-old male presented to our hospital with paralysis of the left upper extremity without any cause or prior injury. He had a history of severe AD. We performed C3–C7 posterior decompression and instrumented fusion based on the diagnosis of cervical spondylotic amyotrophy. One year after surgery, his deltoid and bicep muscle strength were fully recovered. Nevertheless, his neck pain worsened 2 years after surgery following worsening of AD. One month after that, he developed severe myelopathy and was admitted to our hospital. Radiographic findings showed that all the screws had loosened and the retropharyngeal space had expanded. Magnetic resonance imaging and computed tomography showed severe abscess formation and destruction of the C7/T1 vertebrae.Result: We diagnosed him with delayed surgical site infection. Methicillin-resistant Staphylococcus aureus was identified on abscess culture. The patient responded adequately to treatment with antibiotic therapy and two debridements and the infection subsided.Conclusion: We should consider the possibility of delayed surgical site infection when conducting instrumented spinal surgery in patients with severe AD.

STUDY DESIGN: A retrospective cohort study. PURPOSE: This study aims to investigate postoperative shoulder imbalance (PSI) ≥5 years postoperatively in patients who underwent posterior spinal fusion using hooks at the upper instrumented vertebra (UIV) for Lenke type 1 adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE: Studies have reported PSI due to excessive correction of the main thoracic curve. METHODS: We examined 56 patients with AIS who underwent a posterior spinal fusion with hooks at the UIV from 2004 to 2010. Of these, we enrolled 14 patients who underwent surgery, at least, 5 years ago. X-rays and Scoliosis Research Society-22 (SRS-22) questionnaire were administered. To evaluate the shoulder balance, T1 vertebral tilt angle (T1 tilt), clavicle angle, and radiographic shoulder height (RSH) were measured. PSI was considered as the absolute value of the postoperative RSH being ≥20 mm. Based on radiographs obtained immediately postoperatively, we divided patients into two groups as follows: the balanced group (absolute value of RSH <20 mm) and imbalanced group (absolute value of RSH ≥20 mm). RESULTS: The frequency of PSI was 28.6% immediately postoperatively, 0% 2 years postoperatively, and 7.1% at the last follow-up. In the balanced group, PSI did not occur even at 2 years postoperatively or at the last follow-up. In the imbalanced group, PSI was improved in all patients 2 years postoperatively and all patients, except one patient, at the last follow-up. No significant differences were noted in the frequency of distal adding-on at 2 years postoperatively or the last follow-up between the balanced group and the imbalanced group. We observed moderate negative correlations between the absolute value of T1 tilt and the SRS-22 pain and satisfaction at the last follow-up. CONCLUSIONS: Hooks at the UIV could adjust the shoulder balance to avoid long-term PSI in patients with AIS.

　　A 48-year-old man with jaundice was referred to our hospital. Endoscopic retrograde cholangiography showed primary sclerosing cholangitis. Endoscopic biliary drainage was not successful because of highly viscous bile, so we performed percutaneous trans-gallbladder drainage (PTGBD), which was able to reduce the total serum bilirubin level from 8 to 10mg/ml. Subsequently, an indwelling drainage catheter was placed in the gallbladder for 13 months. However, liver atrophy worsened with the gradual progression of hepatic failure. Twelve months later, he complained of dyspnea. Computed abdominal tomography showed that the drainage catheter had perforated the diaphragm and become exposed to the chest cavity. In spite of intensive care, the patient died of liver failure while waiting for a liver transplant. Careful attention should be paid to the possibility of this serious complication in such patients.

Objective: Aerobic exercise on land decreases arterial stiffness, however, the effect of exercise in water on arterial stiffness has not been clear. This study investigated the effect of a 15-min cycling exercise on land and that in water on pulse wave velocity (PWV) as an index of arterial stiffness. Methods: Nine healthy young men were randomly performed exercise on land and exercise in water equivalent to 50% of each maximum oxygen uptake on separate days. The PWV from carotid to femoral artery (aortic PWV) and femoral to posterior tibial artery (leg PWV) were measured at baseline and 15, 30, 60 min after exercise. Results: The heart rate in water was significantly lower during exercise than that on land. In addition, the carbon dioxide output and respiratory exchange ratio during exercise were significantly greater in water. Body temperature increased after the exercise on land but decreased after the exercise in water. Although the aortic PWV and leg PWV decreased concomitantly with decrease in SBP and DBP after the exercise on land, there were no significant changes after the exercise in water. Conclusion: Although acute exercise on land decreased arterial stiffness after exercise, acute exercise in water of the same exercise load did not. The differences in body temperature and blood pressure after exercise may result in diverse arterial stiffness after exercise.

To investigate a relationship between gender differences in recovery from skeletal muscle fatigue and muscle oxygenation, we examined whether there is a difference in oxygen supply and consumption of the working muscles after intermittent handgrip exercise between young males and females using near-infrared spectroscopy (NIRS). Healthy young subjects (25.8±3.9 years ; males, n=10 ; females, n=10) repeated static maximal voluntary contractions (MVC) with a handgrip for 5 seconds followed by 5 seconds rest for a period of 4 minutes in Study 1. The MVC force was measured before, each minute during the handgrip exercise, and 2, 5, and 10 minutes following the exercise. In Study 2, the selected 10 subjects (males, n=5 ; females, n=5) performed the same exercise and their total- and deoxy- hemoglobin/myoglobin level was measured using the venous occlusion NIRS method; and O₂ supply index (OSI) and O₂ consumption index (OCI) calculated before and after the exercise. In Study 1, females exhibited higher %MVC force at the end of the exercise and during the recovery period than males (p<0.05). In Study 2, the %OSI was significantly lower in females than in males at 5 and 10 minutes in the recovery period (p<0.05), but no significant differences were detected in %OCI. Furthermore, %MVC of the recovery period correlated with %OCI of the recovery period in females (r=0.724, p=0.015), but not in males. These findings suggest that female working muscles can convert consumed oxygen more effectively after an intermittent handgrip exercise, and therefore, be able to recover muscle force faster.

A 68-year-old woman received aortic valve replacement (AVR) with a Freestyle stentless valve using a subcoronary technique for aortic stenosis and regurgitation in September 2000. She complained of chest pain, had low grade fever and findings of inflammation and was admitted to our hospital with a diagnosis of acute myocardial infarction in December 2000. She suffered from repetitive or recurrent myocardial infarction. Transesophageal echocardiogram revealed no abnormal findings of the Freestyle stentless valve, but her blood culture was positive for methicillin-resistant coagulase negative Staphylococcus aureus (MRCNS) and she underwent an emergency operation. The Freestyle stentless valve was removed and replaced with a mechanical valve. The patient's intraoperative tissue grew MRCNS and parenteral antibiotics were administered for 8 weeks after surgery. Her condition was complicated with multiple cerebral infarction, however she was discharged on the 113th postoperative day and is doing well without recurrence of infection 12 months after the operation.

A 69-year-old woman underwent aortic valve replacement (AVR) for prosthetic valve (Freestyle^TM stentless valve) endocarditis (PVE) in April 2001. The patient was admitted to our hospital with diarrhea and tarry stools in January 2002 and was treated with intravenous hyperalimentation. She had fever and inflammatory findings at 1 week after admission, and was given intravenous antibiotics. Symptoms and laboratory findings improved gradually, but transesophageal echocardiography revealed a mobile mass in the ascending aorta near the noncoronary sinus of Valsalva. The serum β_-D glucan level was elevated and blood culture was positive for Candida parapsilosis. These findings suggested fungal endocarditis of the ascending aorta, so the patient underwent surgery. Vegetation was attached to the aortic wall near the noncoronary sinus of Valsalva. It was removed with part of the ascending aorta, followed by reconstruction with a gusset xenograft. In addition, aortic valve replacement was performed with a mechanical valve. The resected tissue grew C. parapsilosis, so parenteral anti-fungal drugs were administered intravenously for 8 weeks after surgery. Although cerebral infarction occurred, she was discharged on the 133rd postoperative day. There was no recurrence of infection and she remained on oral anti-fungal medication for 24 months postoperatively.

To clarify the core competencies developed through postgraduate clinical training, we analyzed the conditions of our residency program with qualitative research methods. Seven residents (6 first-year residents and 1 second-year resident) answered a questionnaire and underwent semistructured interviews about postgraduate training. We also worked with the residents as “participant observers” of the treatment team. We found that residents often had trouble formulating diagnostic/treatment plans and tended to rely excessively on laboratory data to make decisions. We attribute these problems to a lack of practice in questioning expectations. We hypothesized that mitate-ryoku, the ability to describe the course of a patient's illness, is an extremely important clinical competency. According to the hypothesis, we tried to listen to the residents' description and to discuss it logically as colleagues. The residents described the patients expected condition over the next few days, considering both data and information they obtained from interviews and physical examinations. They adapted their ideas through logical discussion and were thus able to make acceptable decisions by themselves.

A program for teaching basic clinical skills to fifth-year medical students was started at Toyama Medical and Pharmaceutical University in 1999. The five units of basic clinical skills included: 1) medical interviewing, 2) general physical examination, 3) chest examination, 4) abdominal examination, and 5) neurologic examination. The educational strategies and evaluations in each unit consisted of: 1) lectures, 2) videotape demonstrations, 3) role-playing in small groups, 4) practice on patients in small groups, 5) written examinations, and 6) objective structured clinical examinations. The students evaluated each session of the program with a five-grade rating scale and comments. Small-group sessions (role play and practice on patients) and objective structured clinical examinations received the highest scores, followed by videotape demonstrations. Lectures received significantly lower scores than did other parts of the program. In addition, most students recommended standardization of educational content, increased practice time, and fewer lectures. We conclude that evaluation by students is essential for improving programs for teaching basic clinical skills.
