Early restricted oxygen therapy after resuscitation from cardiac arrest (ER-OXYTRAC): protocol for a stepped-wedge cluster randomised controlled trial.

Introduction: Cardiac arrest is a critical condition, and patients often experience postcardiac arrest syndrome (PCAS) even after the return of spontaneous circulation (ROSC). Administering a restricted amount of oxygen in the early phase after ROSC has been suggested as a potential therapy for PCAS; however, the optimal target for arterial partial pressure of oxygen or peripheral oxygen saturation (SpO) to safely and effectively reduce oxygen remains unclear. Therefore, we aimed to validate the efficacy of restricted oxygen treatment with 94%-95% of the target SpO during the initial 12 hours after ROSC for patients with PCAS.

Uric acid and neurological disease: a narrative review.

Hyperuricemia often accompanies hypertension, diabetes, dyslipidemia, metabolic syndrome, and chronic renal disease; it is also closely related to cardiovascular disease. Moreover, several epidemiological studies have linked hyperuricemia and ischemic stroke. However, uric acid may also have neuroprotective effects because of its antioxidant properties.

Characteristics of patients who received helicopter emergency medical services in Japan from 2012 to 2019: a retrospective analysis of data from Tochigi Prefecture.

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.

Phenytoin versus other antiepileptic drugs as treatments for status epilepticus in adults: a systematic review and meta-analysis.

Aim: Status epilepticus (SE) is a life-threatening neurological emergency. There is insufficient evidence regarding which antiepileptic therapy is most effective in patients with benzodiazepine-refractory convulsive SE. Therefore, this study aimed to evaluate intravenous phenytoin (PHT) and other intravenous antiepileptic medications for SE.

Characteristics of Emergency Neurological Patients Who Were Transported by Helicopter Emergency Medical Services in Tochigi, Japan.

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 (2010-2018), we assessed the characteristics of 1,170 emergency neurological patients (e.g.

Levetiracetam versus fosphenytoin as a second-line treatment after diazepam for status epilepticus: study protocol for a multicenter non-inferiority designed randomized control trial.

Background: Status epilepticus (SE) is an emergency condition for which rapid and secured cessation is important. Phenytoin and fosphenytoin, the prodrug of phenytoin with less severe adverse effects, have been recommended as second-line treatments. However, fosphenytoin causes severe adverse events, such as hypotension and arrhythmia.

Comparison of diazepam and lorazepam for the emergency treatment of adult status epilepticus: a systemic review and meta-analysis.

Status epilepticus (SE) is a life-threatening medical and neurological emergency. Prompt recognition and treatment are essential to stop the seizure and improve patient outcomes. To elucidate which benzodiazepine should be used as the first-line treatment, a systemic search of the PubMed, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi databases was carried out to identify randomized controlled trials (RCTs) comparing i.

Novel clinical features of nonconvulsive status epilepticus.

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.

Recurrent juvenile ischemic stroke caused by bow hunter's stroke revealed by carotid duplex ultrasonography.

Bow hunter's stroke (BHS) is a rare cause of vertebrobasilar insufficiency due to rotational vertebral artery (VA) occlusion associated with head turning. We report a juvenile patient presenting with recurrent ischemic stroke caused by BHS, which was revealed by carotid duplex ultrasonography. Carotid duplex ultrasonography performed in the neutral position showed normal findings.

Postpartum migraines: a long-term prospective study.

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.

Evaluation of olfaction in patients with migraine using an odour stick identification test.

Aims: Peculiar characteristics of migraine headaches include the arousal of olfaction during the attacks and osmophobia. We performed an olfactory test to evaluate the association between olfaction and migraines.

Methods: We evaluated olfactory dysfunction in 80 migraine patients (31 experienced migraines with aura (MWA), 49 migraine without aura (MWOA)) and 30 healthy controls.
