The OSIT showed certain odours to be highly offensive to migraine patients even when they were not experiencing migraine headaches. More attention should be paid to odours that are perceived to be offensive by migraine patients, particularly those with MWA.
Objective There are many reports regarding the course of migraines during pregnancy. However, the prevalence and characteristics of migraines during the postpartum period have not been adequately investigated. We prospectively investigated the patients suffering from migraines over a long postpartum period in an obstetrics department in Japan. Methods We investigated the course of migraines experienced during the postpartum period by patients in a postnatal ward. The patients were surveyed during the first postpartum week and 1, 3, 6 and 12 months after delivery. The patients were provided a headache diary to assess medication use and migraine attack frequency, severity (the faces pain scale) and duration. Results The migraine remission rate was 63%, 83% and 85% during the first, second and third trimesters, respectively. No patient experienced a worsening of headaches during pregnancy. Headache recurrence during the first month after delivery was more frequent in the patients >30 years of age than in those ! 30 years of age (p<0.05). The percentage of women experiencing recurrence at 1, 3, 6 and 12 months after delivery was 63%, 75%, 78% (n=60) and 87.5% (n=40), respectively. In breastfeeding patients, the rates were 50%, 65.8%, 71.1% and 91.7% and in bottle feeding patients, the rates were 86.4%, 90.9%, 95.5% and 81.3%, respectively. Conclusion We found that 85% of the patients with migraines experience remission during pregnancy and that more than 50% experience recurrence during the first month after delivery. Until six months after delivery, breastfeeding is associated with a lower recurrence rate than bottle feeding.
In Japan, reports on the association of individual characteristics, and geographical distance and time with clinical outcomes for neurological emergencies involving helicopter emergency medical services (HEMS) are scarce. Using Tochigi HEMS data (2010, we assessed the characteristics of 1,170 emergency neurological patients (e.g., stroke, neurotrauma, and seizure) at the base hospital, which covered 58% of all HEMS patients in the prefecture. After initial treatment in the emergency room, emergency physicians confirmed the clinical outcomes of each patient compared to those at the incident sites (recovery/ non-recovery). We calculated the geographic distance from the base hospital to each incident site, and estimated and adjusted odds ratios (aOR) and 95% confidence intervals (CI) for non-recovery against distance. The mean distance between the incident site and base hospital was 22.0 ± 11.7 km, and 77.4% of patients recovered following initial treatment. Two peak age groups were observed among emergency neurological diseases, including seizures in patients who were aged < 5 years and stroke and neurotrauma in patients who were aged 70-80 years. The percentages of stroke, traumatic head and brain injury, and seizure were 35.8%, 29.2%, and 22.8%, respectively. The incidence of stroke (aOR = 11.8,) and neurotrauma (aOR = 4.86, 95% CI 2.78-8.51) independently predicted a poor prognosis. However, no significant association was observed with the distance from the base hospital. Therefore, in the Tochigi prefecture, geographical disparities may not affect the short-term prognosis of patients with neurological emergencies who were transported by HEMS.
Background Helicopter Emergency Medical Services (HEMS) has been in operation in Japan since 2001, allowing patients almost anywhere in the nation to receive on-scene emergency treatment from physicians. However, there is insufficient literature on the characteristics of the patients who use Japanese HEMS. Thus, this study aimed to investigate the overall characteristics of patients receiving HEMS care within a single prefecture in Japan. Methods We retrospectively analyzed the data of 5163 patients—in Tochigi Prefecture—who received HEMS care from 2012 to 2019. Descriptive statistics were used to analyze the following aspects of care: diagnosis, severity, background characteristics, geographical and environmental variables, immediate pre-hospital intervention, transportation type, and short-term clinical outcomes. Results Among 7370 HEMS requests received during the study period, treatment was provided to 5163 patients (1.8 cases per day; 3489 men [67.6%]). Nearly 55% (n = 2856) of patients were aged above 60 years. Age peaks were observed at 0–9 years and 60–69 years. The median distance from the base hospital to the site was 26.7 km. The age-standardized rate of HEMS treatment was 30.3 patients per 100,000 people. Cases of trauma and cardiovascular diseases were the most common (65.3%). Most individuals aged 0–9 years and 60–69 years had neurological disease (seizures accounted for 80.5% of this group) and cardiovascular disease, respectively. The number of patients was similar across all four seasons. After immediate pre-hospital intervention, 81.6% of patients receiving HEMS care were transferred by the helicopter ambulance (53.4% and 28.2% to the base hospital and to other hospitals, respectively). Overall, 56.6% of patients receiving HEMS care were transferred to the base hospital, and the short-term recovery rate was above 75%. Intravenous drip and oxygen administration were the most common pre-hospital interventions (93.1% and 72.7%, respectively). Conclusions This study is the first to describe the overall characteristics of HEMS patients using comprehensive data of all HEMS patients in one prefecture in Japan. Further research using both local- and national-level data is needed to accelerate the understanding of the benefits of HEMS.
Nonconvulsive status epilepticus (NCSE) has rapidly expanded from classical features such as staring, repetitive blinking, chewing, swallowing, and automatism to include coma, prolonged apnea, cardiac arrest, dementia, and higher brain dysfunction, which were demonstrated mainly after the 2000s by us and other groups. This review details novel clinical features of NCSE as a manifestation of epilepsy, but one that is underdiagnosed, with the best available evidence. Also, we describe the new concept of epilepsy-related organ dysfunction (Epi-ROD) and a novel electrode and headset which enables prompt electroencephalography.
