RESUMEN
Background: Nagasaki Prefecture is located in the most western part of Japan, and there are a considerable number of clinics in its many remote islands and rural areas. Thus, the Regional Medical Support Center in Nagasaki Prefecture dispatches doctors to rural hospitals to provide medical support. We introduced an outpatient training program at these rural hospitals for all residents to improve their clinical training in the field of otorhinolaryngology, whereby one otolaryngologist trains one resident. Methods: This otolaryngology outpatient training program is randomly assigned, and conducted for 4-5 days a year, transported by a helicopter in Nagasaki Prefecture, which is a 30-minute one-way trip. We used a case checklist that included the 35 items that should be experienced and are defined as frequent by the Ministry of Health, Labor and Welfare. We also conducted a survey using an anonymous questionnaire. Results: The survey response rate was 100%. Comparing the experience rate of symptoms between the pre-introduction resident and the post-introduction resident who underwent the otolaryngology outpatient training program, the experience rates of common diseases, including vertigo and otolaryngologic symptoms such as nasal bleeding and hoarseness, significantly increased after the program was introduced (p ≤ .001). Notably, the experience rate of headache, cough/sputum, and vertigo was 100%. Conclusion: Our training program provides a suitable medical environment for the resident and secures a doctor who can provide secondary medical service support. Furthermore, the program will improve the level of primary care provided by the residents in remote island and rural area hospitals.
RESUMEN
OBJECTIVE: The aim of this study was to compare the prognosis and time reduction between helicopter emergency medical services (HEMS) with a physician and ground emergency medical services (GEMS) in acute myocardial infarction (AMI) cases. METHODS: This is a registry-based study of the Japan Helicopter Emergency Medical Service Registry from April 1, 2015, to March 31, 2018. RESULTS: A total of 605 cases of AMI were registered in the HEMS group and 794 cases in the GEMS group. In the cases of non-cardiopulmonary arrest (CPA), the prognosis between HEMS and GEMS did not differ significantly. Regarding the road distance, for ranges of 20 to 40 km and > 40 km, the times from the call to the angiography room were significantly shorter with HEMS than GEMS (median 91 vs. 97 minutes, P = .036 and 101 vs. 132 minutes, P = .002, respectively). In cases of CPA, HEMS had a higher rate of return of spontaneous circulation than GEMS (55.3% vs. 36.8%, P = .038), but HEMS had a lower prognosis than GEMS (22.9% vs. 38.9%, P = .036). CONCLUSION: The present study suggested that HEMS had an advantage in reducing the time to angiography in AMI cases of non-CPA. In cases of CPA, HEMS increased the return of spontaneous circulation without improving the prognosis.

In April 2020, a coronavirus disease (COVID-19) outbreak occurred on the cruise ship Costa Atlantica in Nagasaki, Japan. Our outbreak investigation included 623 multinational crewmembers onboard on April 20. Median age was 31 years; 84% were men. Each crewmember was isolated or quarantined in a single room inside the ship, and monitoring of health status was supported by a remote health monitoring system. Crewmembers with more severe illness were hospitalized. The investigation found that the outbreak started in late March and peaked in late April, resulting in 149 laboratory-confirmed and 107 probable cases of infection with severe acute respiratory syndrome coronavirus 2. Six case-patients were hospitalized for COVID-19 pneumonia, including 1 in severe condition and 2 who required oxygen administration, but no deaths occurred. Although the virus can spread rapidly on a cruise ship, we describe how prompt isolation and quarantine combined with a sensitive syndromic surveillance system can control a COVID-19 outbreak.

AIMS: The fact that Metabolic Syndrome (MetS) increases the risk of atherosclerosis has been epidemiologically studied and proven; however, a prospective study on the prevalence of MetS in stroke patients has never been conducted because of the difficulty in diagnosis under critical illness in the acute phase. Therefore, we conducted a prospective multicenter study to investigate the prevalence of MetS in stroke patients with modified diagnostic criteria for MetS. METHODS: Stroke patients admitted in the seven participating Emergency and Critical Care Centers within the two years from April 2007 were registered in this study as a prospective multicenter study. Inclusion criteria were 50 to 89 year-old stroke patients who presented within three days from the onset of symptoms. A total of 992 subjects were classified according to the stroke type and the prevalence of MetS and the associated risk factors were investigated. The participants in a medical checkup without any history of a stroke were enrolled as the control group, and compared between the two groups. RESULTS: The prevalence of MetS as well as hyperglycemia and dyslipidemia in the infarction group was significantly higher than that in the non-stroke group. While the hemorrhage group showed no significant difference in the prevalence of MetS, only hypertension was significantly high. According to a subtype analysis, there is a significant correlation between waist circumference increment of the stroke patients and the prevalence of the risk factors of hypertension, hyperglycemia and dyslipidemia. CONCLUSIONS: Different risk factors are significantly related to the type of stroke.
RESUMEN
Hypertensive intracerebral hemorrhage (HICH) causes significant morbidity and mortality. The time required to transport the patients to a specialized hospital can influence the prognosis. In the isolated islands in Nagasaki prefecture, there is no medical institution which can offer emergent neurosurgical intervention. We reviewed the cases of HICH in this region from January 2006 to September 2010, who were transferred to Nagasaki Medical Center by a helicopter after consultation via teleradiology. Eighty four cases (23%) were transferred via helicopter to our institution from isolated islands. In three of them (4%), re-hemorrhage was demonstrated on computed tomography after helicopter transportation, and one of three had been administered an anti-coagulant agent. Only one case (1%) has deteriorated during helicopter transportation because of acute obstructive hydrocephalus. The outcome at discharge was as follows: modified Rankin Scale (mRS) I: 3 cases (4%), II: 5 cases (6%), III: 3 cases (4%), IV: 30 cases (36%), V: 31 cases (37%), VI: 12 cases (14%), 43 cases (51%) showed poor outcome (mRS V, VI). For medical management in isolated islands, a remote teleradiology system is indispensable to decide a strategy of treatment rapidly, and a helicopter transportation system is very useful in cases requiring emergent neurosurgical intervention, particular in cases of impending cerebral herniation or acute hydrocephalus. However, we may need to expand logistical supporting hospitals or secure other transportation facilities because many of the patients with poor outcome can not return to their home islands.

Rheumatoid pericarditis occurs in patients with rheumatoid arthritis (RA). However, cardiac tamponade due to rheumatoid pericarditis is rare; we describe a case of a 72-year-old man with a 6-year history of rheumatoid arthritis who developed rheumatoid pericarditis with recurrent cardiac tamponade. The patient experienced relapse of the cardiac tamponade despite treatment with pericardiocentesis. Therefore, the patient underwent surgical pericardial drainage. The patient was also subsequently treated with increasing doses of corticosteroid, methotrexate and leukocytapheresis. These treatments resulted in a successful outcome without any complication. This case suggests that in addition to immunosuppressive therapy, pericardial drainage should be considered in the treatment of life-threatening refractory cardiac tamponade caused by rheumatoid arthritis.
