Previous studies have suggested a possible association between meteorological factors and the onset of subarachnoid hemorrhage (SAH). We aimed to investigate the relationship between the onset of SAH and meteorological factors based on an hourly time-series analysis. We collected hourly data on transportation of patients with SAH using the ambulance records(More)
INTRODUCTION Our aim in this study was to assess whether the new Glasgow Coma Scale, Age, and Systolic Blood Pressure (GAP) scoring system, which is a modification of the Mechanism, Glasgow Coma Scale, Age, and Arterial Pressure (MGAP) scoring system, better predicts in-hospital mortality and can be applied more easily than previous trauma scores among(More)
BACKGROUND Few studies have investigated ambulance utilization in people aged 85 years or older, ie, the oldest old. METHODS We conducted a 1-year population-based observational study of patients transported by ambulance to emergency departments in Tokyo, Japan, which has a population of about 12 million. Demographic data, symptoms/events associated with(More)
BACKGROUND Measures of aortic occlusion (AO) for resuscitation in patients with severe torso trauma remain controversial. Our aim was to characterize the current use of resuscitative endovascular balloon occlusion of the aorta (REBOA) and resuscitative open aortic cross-clamping (ACC), and to evaluate whether REBOA should be an alternative method to(More)
INTRODUCTION The incidence of asthma exacerbation has been increasing in many countries. Environmental factors may play an important role in this trend. We aimed to investigate the relationship of weather conditions and air pollution to significant exacerbation of asthma. METHODS The daily number of emergency department (ED) visits by ambulance for asthma(More)
BACKGROUND Complete neurological recovery is of great importance to survivors of cardiac arrest. Few studies have explored predictors of good cerebral performance outcomes among these. METHODS We analyzed data from the SOS-KANTO study, a prospective, multi-center, observational study on patients who had out-of-hospital cardiac arrest. We included patients(More)
Spinal epidural hematoma (SEH) is a rare but serious condition. Common causes of SEH include spinal fracture, spinal trauma, and invasive spinal procedures such as lumbar puncture, epidural anesthesia, or myelography. A few previous reports have suggested that SEH could be caused by minor triggers such as spinal manipulation therapy or spontaneously in rare(More)
INTRODUCTION Helicopter emergency medical services with a physician (HEMS) has been provided in Japan since 2001. However, HEMS and its possible effect on outcomes for severe trauma patients have still been debated as helicopter services require expensive and limited resources. Our aim was to analyze the association between the use of helicopters with a(More)
BACKGROUND Previous studies have suggested a possible association between meteorological factors and the occurrence of trauma, but with conflicting results. This study investigated the relation of the occurrence of trauma with meteorological factors, including barometric pressure, ambient temperature, relative humidity and rainfall. METHODS Hourly data(More)
Carbonized polyethylene microspheres of 3.53 gm diameter were injected intravenously into splenectomized, laparotomized, and untreated rats. The number of Kupffer cells which phagocytosed microspheres and the number of microspheres phagocytosed by single Kupffer cells were counted. The number of Kupffer cells which phagocytosed microspheres was 1.51 times(More)
