Introduction: To visualize the damage to primary care facilities in Miyazaki prefecture caused by the Nankai Trough earthquake by collating GIS data and to propose feasible countermeasures based on the estimated damage.Methods: The merged data of the estimated tsunami damage downloaded from the service for numerical information on national land use created by the Ministry of Land, Infrastructure, Transport and Tourism were combined with the data of medical institutions collected from the regional medical information system of the Japan Medical Association.Results: Of the 721 clinics and 140 hospitals, 139 clinics and 31 hospitals were affected, with 521 and 4,713 beds, respectively. By medical area, regions in which more than 50% of the clinics and hospitals were affected included the northern region of Nobeoka Nishi-usuki (clinics, 58.7%; hospitals, 60.0%) and Hyuga Irigo (clinics, 84.2%; hospitals, 61.5%), revealing a disproportionate estimate of damage.Conclusion: To deal with long-term damage, joint operation among regional facilities in neighboring prefectures is essential for a community continuity plan. Care facilities can take initiatives for cooperative disaster risk reduction planning with residents.

In order to examine the personal space perception, measurements were conducted on both elbows in 14 men and 46 women. Each subject, with his (or her) eyes closed and with his upper arm fixed horizontally, was instructed to stop the vertical and horizontal swing motion of his lower arm at the point he considered to be the middle of the range of possible motion on the front and side of plane at his shoulder, and this was repeated ten times. In various conditions, similar measurements were also done to study factors affecting the personal space perception in 14 men.
Mean values of bisected angles in percentage against range of motion were deviated from the middle points in the direction of the elbow extension, although there were large differences between the individuals. The deviation was smallest in the vertical. side of plane, and was larger in the horizontal plane than that in the vertical plane. The deviation was not so much affected by the various conditions.
It was suggested that the gain of the personal space perception is higher in the elbow extension than in the elbow flexion and its difference is larger in the horizontal plane than in vertical plane of the human elbow joint.

To detect the type of contact dermatitis caused due to the handling of Alstroemeria wilhelmina, 1% α-methylene-γ-butyrolactone (α-MBL) dissolved in physiological saline and a five-fold diluted saline solution of original extracts of flowers, leaves and stems of the flower were applied to guinea-pigs for induction treatment, and 0.1% α-MBL physiological saline and a ten-fold diluted solution of the original extracts were applied to the animals as the challenge treatment in compliance with the guinea-pig maximization test (GMT). As a consequence, not only primary irritant dermatitis was observed, but also delayed type allergic contact dermatitis due to Alstroemeria wilhelmina was observed. α-MBL determined in the extracts using high-performance liquid chromatography (HPLC) was found to be the biochemical material cause of the contact dermatitis. The flower region contained α-MBL in the highest concentrations compared with those of the leaves and stems. Therefore, the quantification of α-MBL in the extracts was concluded as being a useful evaluating method for contact dermatitis due to the handling of Alstroemeria.

The purpose of this study was to investigate the factorial structure of life satisfaction in agricultural workers. One hundred and sixty−five (87 males and 78 females) agricultural workers mainly engaged in plastic greenhouse cultivation in southern Japan, ranging in age from 19 to 72 years (mean = 44.3 years), completed a questionnaire. Scores of life satisfaction showed a higher tendency in males than in females, and those in elders were higher than in younger people. Conversely, females showed higher stress scores than males, and younger people’s score were higher than the elders. Multiple regression analysis was performed to analyze the factorial structure of satisfaction. It is suggested that the level of life satisfaction is positively related to social support, and is negatively related to the impact of stressful life events, globally perceived stress and subjective symptoms of ill health. Stress levels depended on factors concerning the psychological demands of work, work posture, work hours and work environment. Different factorial structures were observed between female and male workers. Findings from this study suggest that a strong social support network may assist in enhancing life satisfaction. Furthermore, the ill health and stress experienced in agricultural work were associated with a reduced life satisfaction.

This study was conducted to determine whether the regional factors were related to the increase in the percentage of low birthweight(LBW: <2, 500g) infants in Kumamoto Pref., and to establish a tentative structure model for predicting low birthweight infants. Analyses for frequency of LBW infants between 1974 and 1997, and a multiple regression model and covariance structure model were conducted using data from the vital statistics between 1992 and 1997 and regional indicators concerned with LBW infants from official registered statistical data between 1992 and 1997. The 72 regional factors were clustered into four groups linked with agricultural areas such as Urban, Flat, Hilly and Mountainous areas. The recent increase in the incidence of LBW infants resulted from the increase in moderate−LBW(MLBW: 2, 000−2, 500g) infants of full term−LBW infants. There was a steady annual increase in the Urban agricultural area LBW infants since 1992. The two structure analyses revealed that the Urban area had a marked effect on the increase in LBW infants, whereas, farm villages in Hilly or Moutainous areas had less effect on the increase in LBW infants. These findings suggest that the regional factors relating to the mothers’ life−style or regional environments play a key role in the etiology and prevention of LBW, and will be a useful in the analyses using official registered material.

We performed surgery for atrial fibrillation and mitral valve disease on 3 patients along with atrial mapping. Macroreentrant circuits were found in 2 patients and the other patient showed a preexcitation ectopic focus in the left atrium. Right atrial excitation was chaotic in all three patients. Of the two patients with reentry circuits, one patient underwent biatrial incisions and the other patient had only a left atrial incision. In the patient with a preexcitation ectopic focus, we performed cryoablation of that focus and made a left atrial incision in order to prevent the reoccurrence of atrial fibrillation after surgery. Following surgery, one patient experienced transient atrial fibrillation, however, continuous atrial fibrillation was resolved by this procedure and all patients returned to a normal sinus rhythm.

STUDY DESIGN: Preliminary study. PURPOSE: To assess the association of neuropathic pain with chronic low back pain (LBP) and the effect of pregabalin on neuropathic pain in the elderly. OVERVIEW OF LITERATURE: Of those with chronic LBP, 37% were predominantly presenting with neuropathic pain in young adults. Pregabalin is effective for pain in patients with diabetic neuropathy and peripheral neuralgia. No study has reported on the effects of pregabalin for chronic LBP in elderly patients yet. METHODS: Pregabalin was administered to 32 patients (age, > or =65 years) with chronic LBP for 4 weeks. Pain and activities of daily living were assessed using the Neuropathic Pain Screening Questionnaire (NePSQ), the pain DETECT questionnaire, visual analog scale, the Japanese Orthopedic Association score, the short form of the McGill Pain Questionnaire and the Roland Morris Disability Questionnaire. Modic change and spinal canal stenosis were investigated using magnetic resonance imaging. RESULTS: Altogether, 43.3% of patients had neuropathic pain according to the NePSQ and 15.6% patients had pain according to the pain DETECT. The efficacy rate of pregabalin was 73.3%. A significant effect was observed in patients with neuropathic pain after 4 weeks of administration. CONCLUSIONS: Neuropathic pain was slightly less frequently associated with chronic LBP in the elderly. Pregabalin was effective in reducing pain in patients with chronic LBP accompanied with neuropathic pain. Lumbar spinal stenosis and lower limb symptoms were observed in patients with neuropathic pain. We recommend the use of pregabalin for patients after evaluating a screening score, clinical symptoms and magnetic resonance imaging studies.

Objective: The aim of this study was to establish the proper definitions of venous thromboembolism (VTE) and bleeding events for a healthcare database in Japan.
Study Design: Validation study.
Methods: The study comprised patients with VTE or who had undergone orthopedic surgery of the lower extremities and whose outpatient or inpatient medical information from April 1, 2008 to September 30, 2013 was available. The source population of the database was derived from 100 acute-care hospitals. The endpoints were VTE events (deep venous thrombosis [DVT], pulmonary thromboembolism [PE]) and bleeding events (bleeding requiring blood transfusion, intracranial hemorrhage, intraocular hemorrhage, upper gastrointestinal [GI] bleeding, and lower GI bleeding). The frequent events with laboratory data were randomly extracted and evaluated, while all the infrequent events with laboratory data were extracted and evaluated. Positive predictive value (PPV) was defined as the proportion of events judged to be clinical by medical experts of all the extracted events. First, we conducted a test with a small number of cases and then revised the definitions of events. Second, we extracted and evaluated data in 50 patients for VTE and bleeding events patients, based on which we defined the target PPV level between 60 and 70%.
Results: Of the 5,044,743 patients in the database, 36,947 patients underwent orthopedic surgeries of the lower extremities and 3,578 patients experienced a VTE event. The PPV at the first evaluation was 80.0% (8/10) for DVT, 57.1% (4/7) for PE, and 27.3% (6/22) for bleeding events. At the second evaluation using the revised definitions, the PPV were 75.0% (42/56) for VTE and 73.3% (33/45) for bleeding events. Overall, the PPVs for VTE and bleeding events were over 70%. The PPV of the VTE events were 76.9% (30/39) for DVT and 70.6% (12/17) for PE. The PPVs of each type of bleeding event were over 70% except for intracranial hemorrhage (44.4%, 4/9).
Conclusion: The PPV was high for VTE events (75.0%) and bleeding events (73.3%). The definitions used in this study are rational for the identification of VTE, DVT, PE, and bleeding events in the healthcare database in Japan. The definition for each type of bleeding event should be investigated in further studies.

We collected and analyzed large-scale data concerning the fall of stroke inpatients in convalescent rehabilitation wards. Three hundred seventy-four of 1,107 inpatients experienced one fall or more, and 16 factors associated with falls were clarified by the chi-square test. To extract the significant item from a multifactor, the logistic regression analysis of 16 factors was carried out, and we developed an assessment sheet for the risk degree of first fall prediction in stroke inpatients. We selected eight variables as the items on the assessment sheet : history of previous falls, central paralysis, visual impairment, sensory disturbance, urinary incontinence, use of psychotropic medicines, mode of locomotion, and cognitive impairment. The total score of the assessment sheet was ranged from 0 to 10 and the mean score of fallers (6.4±1.5) among subjects was significantly higher than that of non-fallers (5.1±1.9) (p <0.001). When the subjects were classified into three groups, a significant difference (p<0.001) in the tendency of fall incidence in term of days after admission was found among the three groups on the basis of the Kaplan-Meier survival curve.

Osteoporosis and Sarcopenia 2017;3(4):195-200
OBJECTIVES: The prevalence of chronic low back pain (CLBP) increases with age and several mechanisms are involved in the development of CLBP, including osteoporosis; however, no associations with sarcopenia have yet been identified. METHODS: In total, 100 patients with CLBP and 560 patients without CLBP (nCLBP) aged over 65 years were studied. Skeletal muscle mass index (SMI) and percentage of body fat were evaluated using wholebody dual-energy X-ray absorptiometry. Sarcopenia was diagnosed when the relative SMI was more than 2 standard deviations below the mean in young adults. Thus, the cutoff value for sarcopenia was defined according to Sanada's Japanese population data. Paraspinal muscle cross-sectional areas of the lumbar multifidus and the erector spinae muscles were calculated using magnetic resonance imaging. RESULTS: Forty patients (40.0%) from the CLBP group and 149 (26.6%) from the nCLBP group met the criteria of sarcopenia. SMI was significantly lower and the body fat ratio was significantly higher in the CLBP group compared with the nCLBP group. Sarcopenic obesity was significantly observed in the CLBP group. Lumbar multifidus and the erector spinae muscle cross sectional area were significantly lower in the CLBP group. CONCLUSIONS: Elderly patients with CLBP have significantly lower skeletal muscle mass, and age-related mechanisms in sarcopenia are considered to be associated with chronic pain. Therapeutic procedures that are used to treat elderly aging muscle, including muscle strengthening and performance training, can possibly be a treatment for or used to prevent elderly CLBP.
