Convulsive Patients Transported by a Physician-staffed Helicopter in Japan Had Better Outcomes in the Keyword-triggered Dispatch Compared to Postcontact Emergency Medical Technician-triggered Dispatch.

Introduction: We retrospectively analyzed convulsive patient outcomes transported by a physician-staffed Helicopter Emergency Medical Service (doctor helicopter [DH]) using the keyword-triggered dispatch with data from the Japan DH Registry System (JDRS). Upon receiving an emergency call containing critical keywords, such as an ongoing convulsion at the firefighting central command room, immediate dispatch of the DH is requested, in addition to dispatching an ambulance. The keyword-triggered dispatch relied on data obtained from the JDRS.

Evaluation of Difference in Emergency Care Quality by Years of Physician Experience at the Emergency Department.

Objective: To evaluate the effect of emergency medicine training credentials and years of medical experience on various clinical parameters in emergency medicine practice.

Methods: A cross-sectional study was conducted at Juntendo University Nerima Hospital between 1 April 2019 and 31 March 2020. All patients who were transported by ambulance, were examined by emergency physicians, and underwent computed tomography (CT) or magnetic resonance imaging (MRI) in the emergency department were included.

Secondary pulmonary infection by and during systemic steroid treatment for COVID-19: A case report.

Background: Coronavirus disease 2019 (COVID-19)-associated invasive pulmonary aspergillosis presents a diagnostic challenge due to its non-specific clinical/ imaging features, as well as the fact that the proposed clinically diagnostic algorithms do not necessarily apply to COVID-19 patients. In addition, . is a rare cause of opportunistic life-threatening fungal infections.

A Predictive Rule for COVID-19 Pneumonia Among COVID-19 Patients: A Classification and Regression Tree (CART) Analysis Model.

Background: In this study, we aimed to identify predictive factors for coronavirus disease 2019 (COVID-19) patients with complicated pneumonia and determine which COVID-19 patients should undergo computed tomography (CT) using classification and regression tree (CART) analysis.

Methods: This retrospective cross-sectional survey was conducted at a university hospital. We recruited patients diagnosed with COVID-19 between January 1 and December 31, 2020.

Successful Management of Critical Acute Respiratory Distress Syndrome following COVID-19 through Extracorporeal Membrane Oxygenation in a Patient with Concurrent Nephrotic Syndrome Relapse.

A 44-year-old man with coronavirus disease 2019 (COVID-19) and nephrotic syndrome relapse was admitted to our intensive-care unit for respiratory failure. Despite receiving mechanical ventilation and immunomodulators, the patient experienced refractory hypoxemia, necessitating venovenous extracorporeal membrane oxygenation (VV-ECMO) therapy. Due to a worsening renal function, continuous hemodiafiltration was initiated.

One-Year Outcome of Patients with Chest Pain in the Rule-Out Group According to the 0-Hour/1-Hour Algorithm.

The European Society of Cardiology recommends the 0/1-hour algorithm for risk stratification of patients with suspected non-ST-elevation myocardial infarction as class I, level B; however, there are few reports on the long-term prognosis, resulting in a rule-out group. We aimed to determine whether implementation of the 0-hour/1-hour algorithm is safe and effective in emergency department (ED) patients with possible acute coronary syndrome (ACS) through a 1-year follow-up period. Our study analyzed the 1-year follow-up data from a prospective pre-post study of 1106 ED patients with possible ACS from 4 hospitals in Japan and Taiwan.

High doses of dextromethorphan induced shock and convulsions in a 19-year-old female: A case report.

Background: Dextromethorphan is a prevalent antitussive agent that can be easily obtained as an over-the-counter medication. There has been a growing number of reported cases of toxicity in recent years. Generally, there are numerous instances of mild symptoms, with only a limited number of reports of severe cases necessitating intensive care.

Incidence and factor analysis for the heat-related illness on the Tokyo 2020 Olympic and Paralympic Games.

Introduction: Among the 43 venues of Tokyo 2020 Olympic Games (OG) and 33 venues of Paralympic Games (PG) were held, the heat island effect was highly expected to cause heat-related illnesses in the outdoor venues with maximum temperatures exceeding 35°C. However, the actual number of heat-related illness cases during the competition was lower than that was initially expected, and it was unclear under what conditions or environment-related heat illnesses occurred among athletes.

Object: To clarify the cause and factors contributing to the occurrence of heat-related illness among athletes participating in the Tokyo 2020 Olympic and Paralympic Games.

Amebic liver abscess by .

Amebic liver abscesses (ALAs) are the most commonly encountered extraintestinal manifestation of human invasive amebiasis, which results from () spreading extraintestinally. Amebiasis can be complicated by liver abscess in 9% of cases, and ALAs led to almost 50000 fatalities worldwide in 2010. Although there have been fewer and fewer cases in the past several years, ALAs remain an important public health problem in endemic areas.

A rare distributive shock diagnosed only by medical history and inspection.

A 78-year-old Japanese man was in a state of shock with skin flushing. Although he denied, his wife revealed his prescription disulfiram for alcoholism. Disulfiram-ethanol reaction, even though it is a rare cause of distributive shock, could be easily and quickly differentiated only based on accurate medical history and inspection.

Hemorrhagic shock due to submucosal esophageal hematoma along with mallory-weiss syndrome: A case report.

Background: Esophageal submucosal hematoma is a rare condition. Although the exact etiology remains uncertain, vessel fragility with external factors is believed to have led to submucosal bleeding and hematoma formation; the vessel was ruptured by a sudden increase in pressure due to nausea, and the hematoma was enlarged by antiplatelet or anticoagulant therapy. Serious conditions are rare, with a better prognosis.

Obligate aerobic, gram-positive, weak acid-fast, nonmotile bacilli, : Minireview of a rare opportunistic pathogen.

species are obligate aerobic, gram-positive, weak acid-fast, nonmotile bacilli. They are found in various environments, such as soil, water, sludge, and petroleum reservoir wastewater, and belong to the order . In 2016, there was a reclassification of species within the genus , merging the species () and .

ST-Elevation Acute Myocardial Infarction in a Young Man.

Acute myocardial infarction (AMI) in young patients is very rare, but the incidence has increased over years past at younger ages, likely due to the presence of multiple risk factors. We present the first known case of ST-elevation AMI (STEMI) in a young man. A 22-year-old Japanese man was transferred to our hospital due to suddenly occurred anterior chest pain.

Exophiala dermatitidis.

is a genus comprising several species of opportunistic black yeasts, which belongs to Ascomycotina. It is a rare cause of fungal infections. However, infections are often chronic and recalcitrant, and while the number of cases is steadily increasing in both immunocompromised and immunocompetent people, detailed knowledge remains scarce regarding infection mechanisms, virulence factors, specific predisposing factors, risk factors, and host response.
