RESUMEN
Objective Almost no Japanese elderly patients have an advance directive (AD). Our aim was to determine whether or not the wish to receive intensive care in elderly patients with respiratory tract infection could be predicted from the prehospital data. Methods In this retrospective study, we reviewed patients ≥65 years of age with respiratory tract infection who had been transferred to our hospital by ambulance between September 2014 and August 2016. The patients were divided into two groups according to whether or not they wished to receive intensive treatment. We placed patients without a wish to receive intensive treatments (WITs) in Group A and patients with a WITs in Group B. We then analyzed parameters that could be determined in the prehospital phase and compared the findings between the groups. Results Thirty-seven patients were in Group A, and 67 patients were in Group B. None of the patients in this study had an AD. There were significant differences in the age, rate of residence in an extended care facility, frequency of inability to care for oneself fully, frequency of dementia, number of prescribed drugs, and Glasgow coma scale (GCS) on a univariate analysis. A logistic regression analysis showed that the inability to care for oneself fully [odds ratio (OR): 4.521, 95% confidence interval (CI): 2.024-10.096, p<0.001] and a low GCS (OR 0.885, 95%CI 0.838-0.935, p<0.001) were related to a WITs. Conclusion Elderly patients who are unable to care for themselves and who have a low GCS in the prehospital stage are likely not to want intensive treatment.

BACKGROUND: Influenza virus transmission may be prevented by infection control measures, including vaccination, wearing a mask, gargling with water, and hand washing. It is unclear, however, whether these measures affect influenza epidemics in school settings. METHODS: A prospective epidemiological survey in all public elementary schools in Matsumoto City, Japan, during the 2014/2015 season evaluated the number of diagnosed patients in each school and calculated the reproduction number of schoolchildren. At the end of the prospective survey, a cross-sectional survey evaluated the implementation of infection control measures in these schools. Both results were combined and associations among infection control measures including vaccination, mask wearing, hand washing, water gargling, and epidemic level were evaluated. RESULTS: Of the 13,217 schoolchildren in 29 schools, 2548 were diagnosed with seasonal influenza. A significant negative association was observed between vaccination coverage and reproduction number at each school, but not between other infection control measures and the reproduction number. A regression curve with exponential function was most predictive. At 0% vaccination, the reproduction number was estimated to be 1.39. CONCLUSION: These findings provide evidence that high vaccination coverage was associated with reduced epidemic levels in schools and suggest the need for increased vaccination of schoolchildren.

Case: We report a case of post-traumatic hypopituitarism in a 9-year-old boy who was injured in a car accident. Outcome: Post-traumatic hypopituitarism might be caused by moderate to severe head trauma, and while this possibility has recently drawn attention in adults, few reports are available regarding children. Our patient experienced head and facial injury, resulting in post-traumatic hypopituitarism. Six hours after injury he suffered from diabetes insipidus and hormone replacement therapy was started. On day 12 he underwent facial fracture reduction under general anesthesia. On day 24 he was discharged from the hospital. One year after the injury, secretory function and water dehydration tests suggested the possibility of post-traumatic hypopituitarism. Conclusion: We experienced a child case of post-traumatic hypopituitarism. Emergency physicians should pay attention to the possibility of post-traumatic hypopituitarism in cases of traumatic brain injury.
RESUMEN
Useful parameters that can predict return of spontaneous circulation (ROSC) in patients with cardiopulmonary arrest (CPA) have not been established. We previously reported the usefulness of anion gap (AG) and albumin-corrected anion gap (ACAG) calculated from a blood sample obtained on arrival at the hospital for the prediction of ROSC. Otherwise, it has been reported that strong ion gap (SIG), which shows the difference between the levels of fully dissociated cations and anions in the serum, is useful to predict the prognosis of critically ill patients. This was a prospective and observational clinical study. Patients with CPA transferred to the emergency department of our hospital between January 2013 and December 2014 were evaluated. Patients were divided into two groups: patients who obtained ROSC [ROSC(+) group] and those who did not [ROSC(-) group]. We compared AG, ACAG and SIG between the two groups. A total of 170 patients were enrolled. Fifty patients were included in the ROSC(+) group, and the remaining 120 in the ROSC(-) group. Both AG and ACAG were significantly better in the ROSC(+) group; however, there was no significant difference in SIG between the two groups. The area under the receiver operating characteristic curves (AUC) for ROSC of both AG and ACAG were almost the same (0.72 and 0.708, respectively); the AUC of SIG (0.57) was inferior to those of AG and ACAG. Our results suggest that AG and ACAG can better predict ROSC following cardiopulmonary resuscitation (CPR) compared with SIG.
RESUMEN
PURPOSE: To find factors that predict the requirement of packed red blood cells (pRBC) transfusion in patients with blunt trauma on arrival at the hospital. METHODS: We conducted blood tests in trauma patients whose trauma severity was suspected as being 3 and over in the Abbreviated Injury Scale. Patients were divided into the blood transfusion (BT) and control groups according to the requirement of pRBC transfusion within 24h after arrival. RESULTS: We analyzed 347 patients (BT group, n=14; control group, n=333). On univariate analysis, there were significant differences in Glasgow Coma Scale (GCS), rate of positive FAST (focused assessment with sonography for trauma) finding, hematocrit, international normalized ratio of prothrombin time, activated partial thromboplastin time, fibrinogen (Fib), and level of fibrin degradation products (FDP). On multivariable analysis, positive FAST finding, GCS, Fib, and FDP influenced the requirement of pRBC transfusion. In the area under the receiver operating characteristic curve analysis, Fib and FDP were markers that predicted the requirement of pRBC transfusion. The FDP/Fib ratio had a better correlation with the requirement of pRBC transfusion than FDP or Fib. CONCLUSIONS: The FDP/Fib ratio can be easily measured and may be a predictor of the need for pRBC transfusion.

Measures of seasonal influenza control are generally divided into two categories: pharmaceutical and non-pharmaceutical interventions. The effectiveness of these measures remains unclear, because of insufficient study sample size and/or differences in study settings. This observational epidemiological study involved all elementary schoolchildren in Matsumoto City, Japan, with seasonal influenza during the 2014/2015 season. Questionnaires, including experiences with influenza diagnosis and socio-demographic factors, were distributed to all 29 public elementary schools, involving 13,217 children, at the end of February 2015. Data were obtained from 10,524 children and analyzed with multivariate logistic regression analysis. The result showed that vaccination (odds ratio 0.866, 95% confidence interval 0.786-0.954) and wearing masks (0.859, 0.778-0.949) had significant protective association. Hand washing (1.447, 1.274-1.644) and gargling (1.319, 1.183-1.471), however, were not associated with protection. In the natural setting, hand washing and gargling showed a negative association, which may have been due to inappropriate infection control measures or aggregating infected and non-infected children to conduct those measures. These results may indicate a pathway for influenza transmission and explain why seasonal influenza control remains difficult in school settings. The overall effectiveness of vaccination and mask wearing was 9.9% and 8.6%, respectively. After dividing children into higher (grades 4-6) and lower (grade 1-3) grade groups, the effectiveness of vaccination became greater in the lower grade group, and the effectiveness of wearing masks became greater in the higher grade group. These results may provide valuable information about designing infection control measures that allocate resources among children.
RESUMEN
Seasonal influenza is known to spread within and among educational organizations. Detailed understanding of the pattern of infection requires comprehensive prospective epidemiological studies, involving all schools within a community. This prospective survey evaluated 13,217 schoolchildren attending all of the 29 public elementary schools in Matsumoto City, Japan, in 2014/2015. Questionnaires were distributed to school nurses to obtain information about onset date and suspected route of transmission of influenza for all schoolchildren diagnosed with influenza virus at medical institutions. Responses were obtained for 2,548 infected schoolchildren, representing 96% of reported cases. Epidemic curves were plotted for each school by calculating the numbers of incident cases. Distance between schools was not associated with influenza spread over time. However, modeling showed that the occurrence of initial infection at each school and its spread over time could be fitted with a logistic curve. The transmission route for most children initially infected at each school was through a household member, whereas for most remaining schoolchildren it was through the school. These findings indicated that seasonal influenza was initially transmitted to schoolchildren by household members and then spread throughout the schools, with the initially infected child at each school fitting logistic curves over time.

CASE: A 13-year-old adolescent girl with blunt abdominal injury was transferred to our hospital. Enhanced computed tomography (CT) showed not only retroperitoneal hematoma around the inferior vena cava and left common iliac vein but also thrombus extending from the left common iliac vein to the femoral vein. OUTCOME: Enhanced CT performed on the second day revealed no increase in retroperitoneal hematoma and a new small thrombus in the popliteal vein. Anticoagulant therapy was therefore started with administration of unfractionated heparin. Administration of warfarin was started on the 12th day and heparin administration was stopped on the 14th day. The patient was discharged on the 19th day with continuation of warfarin administration. Enhanced CT performed 10 months after injury showed no thrombus, and the administration of warfarin was then stopped. CONCLUSIONS: She was successfully treated with the appropriate start time and control of anticoagulation therapy based on careful evaluation of her general condition.

PURPOSE: To evaluate the usefulness of coagulation biomarkers, which are easy and quick to analyze in emergency settings, for prediction of arterial extravasation due to pelvic fracture. PATIENTS AND METHODS: The medical records of pelvic fracture patients transferred to the emergency department of Gunma University Hospital between December 2009 and May 2015 were reviewed. Patients were divided into two groups, those with (Extra(+)) and without (Extra(-)) arterial extravasation on enhanced CT or angiography. Levels of fibrin degradation products (FDP), D-dimer, fibrinogen, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, systolic blood pressure, heart rate, the Glasgow Coma Scale, pH, base excess, hemoglobin and lactate levels, the pattern of pelvic injury, and injury severity score were measured at hospital admission, and compared between the two groups. Parameters with a significant difference between the two groups were used to construct receiver operating characteristic (ROC) curves. RESULTS: The study included 29 patients with pelvic fracture. FDP, D-dimer, the ratio of FDP to fibrinogen and the ratio of D-dimer to fibrinogen were the most useful parameters for predicting arterial extravasation due to pelvic fracture. FDP, D-dimer, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, and hemoglobin and lactate levels were significantly higher in the Extra(+) group than in the Extra(-) group (FDP, 354.8µg/mL [median] versus 96.6µg/mL; D-dimer, 122.3µg/mL versus 42.1µg/mL; the ratio of FDP to fibrinogen, 3.39 versus 0.42; the ratio of D-dimer to fibrinogen, 1.14 versus 0.18; hemoglobin, 10.5g/dL versus 13.5g/dL; lactate, 3.5mmol/L versus 1.7mmol/L). The area under the ROC curves for FDP, D-dimer, the ratio of FDP to fibrinogen, the ratio of D-dimer to fibrinogen, hemoglobin and lactate levels were 0.900, 0.882, 0.918, 0.900, 0.815 and 0.765, respectively. CONCLUSION: Coagulation biomarkers, and hemoglobin and lactate levels could be useful to predict the existence of arterial extravasation due to pelvic fracture. The ratio of FDP to fibrinogen and the ratio of D-dimer to fibrinogen were the most accurate markers. Coagulation biomarkers may enable more rapid and specific treatment for pelvic fracture.

Case: A 92-year-old female resident at a nursing home was transported to the emergency department unconscious, hypotensive, and febrile. Chest X-rays and computed tomography revealed a permeation shadow in the right lung. The patient was diagnosed with sepsis due to pneumonia. At the time of admission, she had not received antibiotics or treatment using medical devices over the past 6 months. Two sets of samples were taken for blood and sputum cultures, and Klebsiella pneumoniae was isolated from all cultures. The strain was identified as metallo-ß-lactamase-producing K. pneumoniae, and the patient was successfully treated with tazobactam-piperacillin. This case indicates that metallo-ß-lactamase-producing K. pneumoniae infection occurred in a non-hospital environment. Outcome: After tazobactam-piperacillin treatment, the patient was transferred to another hospital. Conclusion: Emergency physicians should be aware of multidrug-resistant bacterial infection even in a non-hospital setting.
RESUMEN
Case: A 66 year-old woman who presented with sudden lower abdominal pain was transferred to our emergency room. Vital signs were stable on arrival at the hospital, but immediately became unstable. Systolic/diastolic blood pressure and heart rate were 66/33 mmHg and 70 b.p.m., respectively. Computed tomography scanning showed splenic artery aneurysm rupture and extravasation. The patient was treated non-operatively and definitively by endovascular therapy comprising resuscitative endovascular occlusion of the aorta for hemodynamic control, N-butyl cyanoacrylate, and metallic coils as an embolization material. Outcome: On admission day 3, she was enrolled in another department and admission day 54, she was discharged. Conclusion: Although resuscitative endovascular occlusion of the aorta and N-butyl cyanoacrylate is known to be effective, the use of resuscitative endovascular occlusion of the aorta with transcatheter arterial embolization and N-butyl cyanoacrylate for non-traumatic bleeding has not previously been reported. By combining and adapting these devices, their applications in endovascular management may be increased.
RESUMEN
Injury to the inferior phrenic artery after blunt trauma is an extremely rare event, and it may occur under unanticipated conditions. This case report describes an injury to the left inferior phrenic artery caused by blunt trauma, which was complicated by massive hemothorax, and treated with transcatheter arterial embolization (TAE). An 81 year-old female hit by a car while walking at the traffic intersection was transferred to the emergency department, computed tomography scanning revealed active extravasations of the contrast medium within the retrocrural space and from branches of the internal iliac artery. The patient underwent repeated angiography, and active extravasation of contrast medium was observed between the retrocrural space and the right pleural space originating from the left inferior phrenic artery. The injured left inferior phrenic artery was successfully embolized with N-butyl cyanoacrylate, resulting in stabilization of the patient's clinical condition. Inferior phrenic artery injury should be recognized as a rare phenomenon and causative factor for hemothorax. TAE represents a safe and effective treatment for this complication and obviates the need for a thoracotomy.
RESUMEN
OBJECTIVE: This study was conducted to determine whether a policy of not attempting to resuscitate patients who are 80 years of age and older with cardiopulmonary arrest on arrival is justifiable. METHODS: The protocol of this study was approved without the need for informed consent by the research ethics board of Gunma University Hospital. We prospectively analyzed patients with cardiopulmonary arrest on arrival that was due to an intrinsic reason who were taken to Gunma University Hospital between January 2013 and March 2014. The patients were divided into two groups: patients who were less than 80 years of age (L group) and those aged 80 years and older (H group). We compared the patients' characteristics, including the etiology of cardiac arrest, and the prognosis between the two groups. RESULTS: A total of 103 patients with cardiopulmonary arrest on arrival were enrolled. There were no significant differences in the patients' characteristics, such as age, sex, witness and bystander cardiopulmonary resuscitation, and transportation time between the two groups. The return of spontaneous circulation was obtained in 14 patients (25.5%) in the L group and in 9 patients (18.8%) in the H group; however, no significant difference was seen between the two groups. Two patients in the L group were in good neurological condition when they were discharged; however, the other patients did not survive. CONCLUSION: Even patients 80 years of age and older can be resuscitated to spontaneous circulation. We do not endorse a policy that recommends not performing cardiopulmonary resuscitation based solely on the age of the patient.

Aim: To determine the formula that predicts the injury severity score from parameters that are obtained in the emergency department at arrival. Methods: We reviewed the medical records of trauma patients who were transferred to the emergency department of Gunma University Hospital between January 2010 and December 2010. The injury severity score, age, mean blood pressure, heart rate, Glasgow coma scale, hemoglobin, hematocrit, red blood cell count, platelet count, fibrinogen, international normalized ratio of prothrombin time, activated partial thromboplastin time, and fibrin degradation products, were examined in those patients on arrival. To determine the formula that predicts the injury severity score, multiple linear regression analysis was carried out. The injury severity score was set as the dependent variable, and the other parameters were set as candidate objective variables. IBM spss Statistics 20 was used for the statistical analysis. Statistical significance was set at P < 0.05. To select objective variables, the stepwise method was used. Results: A total of 122 patients were included in this study. The formula for predicting the injury severity score (ISS) was as follows: ISS = 13.252-0.078(mean blood pressure) + 0.12(fibrin degradation products). The P-value of this formula from analysis of variance was <0.001, and the multiple correlation coefficient (R) was 0.739 (R2 = 0.546). The multiple correlation coefficient adjusted for the degrees of freedom was 0.538. The Durbin-Watson ratio was 2.200. Conclusions: A formula for predicting the injury severity score in trauma patients was developed with ordinary parameters such as fibrin degradation products and mean blood pressure. This formula is useful because we can predict the injury severity score easily in the emergency department.
RESUMEN
BACKGROUND: To investigate how household background factors affect parental behavior during pandemic influenza-related school closures, we determined associations between such factors and three parental attitudes: "caring for the child", "taking leave from work", and "permitting out-of-home activities". METHODS: A hypothetical pandemic influenza situation was presented and a questionnaire survey among households of 2146 schoolchildren from 6 schools was conducted. Odds ratios of background factors were estimated using univariate and multivariate logistic regression models. RESULTS: Responses pertaining to 1510 children indicated that junior high school (OR = 0.11), both parents working (OR = 0.03), and family including grandparent(s) or other relatives (OR = 7.50) were factors associated with "caring for the child", and elementary school (OR = 2.28), special education school (OR = 3.18), and both parents working (OR = 5.74) were associated with "taking leave from work". Having an older sibling (OR = 0.74) and awareness of the technical term for school closure (OR = 0.73) were factors associated with "permitting out-of-home activities". CONCLUSION: Not only work status but also other household factors may be associated with parental behaviors during pandemic influenza-related school closures.

We confirmed infection of 2 patients with Borrelia miyamotoi in Japan by retrospective surveillance of Lyme disease patients and detection of B. miyamotoi DNA in serum samples. One patient also showed seroconversion for antibody against recombinant glycerophosphodiester phosphodiesterase of B. miyamotoi. Indigenous relapsing fever should be considered a health concern in Japan.

The pandemic influenza A/H1N1 2009 virus is commonly known to affect younger individuals. Several epidemiological studies have clarified the epidemic features of university students in Japan. In this study, we reviewed these studies in Japan in comparison with reports from other countries. The average cumulative incidence rate among university students was 9.6 %, with the major symptoms being cough, sore throat, and rhinorrhea. These epidemiological features were similar between Japan and other countries. Attitudes and behaviors toward pandemic influenza control measures were different before and improved during and after the epidemic. These features were also similar to those in other countries. On the other hand, the epidemic spread through club activities or social events, and transmission was attenuated after temporary closure of such groups in Japan. This transmission pattern was inconsistent among countries, which may have been due to differences in lifestyle and cultural habits. Based on these results, infection control measures of pandemic influenza for university organizations in Japan should be considered.

BACKGROUND: As detailed associations between personality and long work hours are unclear, we assessed associations between personality dimensions and overtime work among Japanese white-collar workers. METHODS: From records of hours worked over 12 months by 267 office workers in an organization within the service industry, average overtime work hours per month and occurrence of excessive overtime was determined for each worker. Excessive overtime was defined as > â 45 overtime work hours per month for at least one month. Responses to a questionnaire assessing socio-demographic and workplace-related factors and the Big Five personality test were analyzed. Associations between personality factors and overtime work were assessed by multivariate logistic regression analysis. RESULTS: Low Extraversion was associated with excessive overtime work (OR 2.02, 95%CI 1.02â -â 4.02, Pâ = â 0.04). CONCLUSIONS: It is suggested that workers with low Extraversion can't share work when busy to avoid excessive overtime. Personality factors should be considered in studies evaluating work time. Moreover, strengthening communication among workers with low Extraversion may reduce excessive overtime work and associated health problems.

AIM: We evaluated the relation between general status on arrival and prognosis in patients aged 90 years and older who were admitted to our department through the emergency room, with the aim of assisting the development of a treatment policy for elderly people. METHODS: We retrospectively analyzed patients aged 90 years and older who were admitted to our department from January 2006 to September 2013. Patients were divided into two groups, patients who were discharged from our hospital or transferred to another hospital, and patients who died in our hospital. Comparisons of the patients' general status and the results of blood examinations were carried out between the two groups. Independent parameters to predict prognosis were also evaluated. RESULTS: Fifty-eight patients were enrolled in this study. The mean age was 93.2 ± 3.4 years (range, 90-106 years). Forty-five patients (77.6%) were discharged from our hospital (group A), and 13 patients (22.4%) died (group B). The percentage of patients with the inability to walk independently was significantly higher in group B. Mean arterial pressure, Glasgow Coma Scale (GCS), PaO2/FiO2 ratio, and serum albumin level on arrival were significantly better in group A. Multivariate logistic regression analysis indicated that the inability to walk independently (odds ratio, 22.4; 95% confidence interval, 4.4-113.1; P < 0.0001) and GCS (odds ratio, 7.0; 95% confidence interval, 1.8-27.7; P = 0.003) were the parameters to predict prognosis. CONCLUSION: The inability to walk independently and GCS (consciousness status) are the most sensitive predictors of prognosis in emergency patients aged 90 years and older.
RESUMEN
AIM: We evaluated the usefulness of fibrin degradation products and D-dimer levels in blood to predict return of spontaneous circulation in patients with cardiopulmonary arrest on arrival compared with anion gap and albumin-corrected anion gap. METHODS: We retrospectively reviewed the medical records of patients with cardiopulmonary arrest on arrival who had been transferred to the emergency department of our hospital in 2012. Patients were divided into two groups: patients with return of spontaneous circulation (ROSC(+) group), and those without (ROSC(-) group). The levels of anion gap, albumin-corrected anion gap, fibrin degradation products and D-dimer measured on arrival were compared between the two groups. RESULTS: Fifty-three patients could be analyzed. The anion gap and albumin-corrected anion gap levels were significantly better in the ROSC(+) group than in the ROSC(-) group (anion gap, 28.7 mmol/L [median] versus 39.1 mmol/L; albumin-corrected anion gap, 31.1 mmol/L versus 40.9 mmol/L). The fibrin degradation product and D-dimer levels were significantly lower in the ROSC(+) group than in the ROSC(-) group (fibrin degradation products, 32.1 µg/mL versus 157.4 µg/mL; D-dimer, 9.9 µg/mL versus 37.4 µg/mL). The area under receiver operating characteristic curves to evaluate the relationship with return of spontaneous circulation of anion gap, albumin-corrected anion gap, fibrin degradation products, and D-dimer were 0.664, 0.667, 0.714, and 0.707, respectively. CONCLUSION: Fibrin degradation products and D-dimer levels might be more useful as predictors of return of spontaneous circulation than anion gap and albumin-corrected anion gap.
