RESUMEN
Dengue is a systemic viral infection, and clinical findings vary from asymptomatic to life-threatening, including shock and neurological complications. Despite efforts in vector control, the disease continues to spread worldwide, and the number of annual dengue infections is estimated to be 390 million. For patients with severe dengue, early diagnosis is important; however, owing to the wide range of symptoms and severity, diagnosis can be difficult. Herein, we report the case of a 24-year-old man from Vietnam who was found to have dengue shock syndrome complicated by meningoencephalitis, even though he did not show the typical clinical manifestations of dengue infection. He was transported to our hospital by ambulance because of fever and altered mental status. Brain magnetic resonance imaging revealed hyperintensities in the bilateral thalamus and brainstem on the T2 sequence. After hospitalization, polymerase chain reaction testing of cerebrospinal fluid, serum, and urine revealed the presence of dengue virus serotype 2. This confirmed the diagnosis of dengue encephalitis. The patient was discharged on day 49 with impaired abduction of the left eye and urinary retention. In this case, the initial differential diagnosis was broad because the patient was unable to provide any medical history owing to altered mental status. In addition, the fact that he did not show the characteristic symptoms of dengue infection initially made the diagnosis very difficult. In conclusion, dengue fever should always be considered as a part of the differential diagnosis when a patient from an endemic area presents with fever and impaired consciousness.
RESUMEN
BACKGROUND/PURPOSE: The aim of this study was to clarify the clinical characteristics of acute cholangitis (AC) after bilioenteric anastomosis and stent-related AC in a multi-institutional retrospective study, and validate the TG18 diagnostic performance for various type of cholangitis. METHODS: We retrospectively reviewed 1079 AC patients during 2020, at 16 Tokyo Guidelines 18 (TG 18) Core Meeting institutions. Of these, the post-biliary reconstruction associated AC (PBR-AC), stent-associated AC (S-AC) and common AC (C-AC) were 228, 307, and 544, respectively. The characteristics of each AC were compared, and the TG18 diagnostic performance of each was evaluated. RESULTS: The PBR-AC group showed significantly milder biliary stasis compared to the C-AC group. Using TG18 criteria, definitive diagnosis rate in the PBR-AC group was significantly lower than that in the C-AC group (59.6% vs. 79.6%, p < .001) because of significantly lower prevalence of TG 18 imaging findings and milder bile stasis. In the S-AC group, the bile stasis was also milder, but definitive-diagnostic rate was significantly higher (95.1%) compared to the C-AC group. The incidence of transient hepatic attenuation difference (THAD) and pneumobilia were more frequent in PBR-AC than that in C-AC. The definitive-diagnostic rate of PBR-AC (59.6%-78.1%) and total cohort (79.6%-85.3%) were significantly improved when newly adding these items to TG18 diagnostic imaging findings. CONCLUSIONS: The diagnostic rate of PBR-AC using TG18 is low, but adding THAD and pneumobilia to TG imaging criteria may improve TG diagnostic performance.

BACKGROUND: Data on the perceptions of medical students on international experience in non-English-speaking high-income countries (HICs) are very limited. This study aimed to assess the perceptions of medical students in Japan toward overseas experience while in school and post-graduation, as well as to characterize the support they require to pursue their profession in international settings. METHODS: A cross-sectional national survey was administered online between September 16, 2020, and October 8, 2020. Participants were recruited from 69 medical schools using snowball sampling through acquaintances and social media platforms. The survey results were analyzed by two researchers. RESULTS: A total of 548 students from 59 medical schools responded to the survey. Among them, 381 respondents (69%) expressed interest in working abroad, while only 40% seriously considered it. The majority of students responded that they would like to pursue clinical training abroad for a short term or while they were medical students (54%) or during a residency/fellowship (53%). The most popular regions among the respondents for future international experiences were North America and Europe. Finally, the most reported reasons for hesitation to work abroad were language barriers (70%), followed by lack of clarity regarding career options after working abroad (67%), difficulties obtaining medical licensure abroad (62%), and the lack of role models (42%). CONCLUSIONS: Although nearly 70% of participants reported a high interest in working overseas, various barriers to working abroad were identified. Our findings identified key problem areas that could be targeted when promoting international experiences for medical students in Japan.

A 77-year-old man arrived at our hospital with bilateral shoulder pain persisting for several months and headache for 1 month. Giant cell arteritis with polymyalgia rheumatica was suspected. However, considering his medical history of testing positive for syphilis, we submitted a sample for a syphilis serology test, which yielded positive results. The Treponema pallidum hemagglutination assay of cerebrospinal fluid was positive, and a temporal artery biopsy revealed vasculitis, confirming the diagnosis of tertiary syphilis. He was successfully treated for two weeks with penicillin G infusions. Symptoms reminiscent of giant cell arteritis and polymyalgia rheumatica may reveal syphilis, which is called the "great imitator."

BACKGROUND: Nurse practitioners (NPs) are known as effective healthcare providers worldwide. In Japan, nurse practitioner adoption is considered to be in a shaky period. Although nurse practitioners were introduced approximately 10 years ago at the initiative of educational institutions in Japan, the full extent of this trend is not known. Therefore, we have clarified the whole picture of nurse practitioners from two directions: the perception of nurse practitioners in Japan and the perception of physicians who work with nurse practitioners. This will inform discussions regarding the recruitment of nurse practitioners at the national level in Japan. METHODS: From 18 June to 24 July 2021, we administered a nationwide cross-sectional survey of NPs and physicians working in the same clinical settings as NPs in Japan. The domains of the survey included "scope and content of work", "perceptions of NPs' clinical practice", and "individual clinical practice characteristics". The survey was distributed and collected digitally. RESULTS: The total number of respondents to the survey was 281, including 169 NPs and 112 physicians; the percentage of NPs who responded was 50.5%. The number of valid responses was 164 NPs and 111 physicians, for a total of 275 respondents. Approximately 60% of NPs are concentrated in Tokyo, the capital of Japan, and the three prefectures adjacent to Tokyo. They also worked fewer hours per week, cared for fewer patients per day, and earned less money than physicians. More physicians than NPs indicated that "more NPs would improve the quality of care". A total of 90.1% of physicians and 82.3% of NPs agreed that "Nurse practitioners should practice to the full extent of their education and training," and 73.9% of physicians and 81.7% of NPs agreed that "Nurse practitioners' scope of practice should be uniformly defined at a national level". CONCLUSIONS: This study clarified the present working conditions of NPs from NPs' and physicians' perspectives in Japanese contexts. Japanese NPs may be able to work effectively in collaboration with physicians. Therefore, the implementation of NPs in Japanese medical conditions should be discussed further for better healthcare.
RESUMEN
We report a patient of an 82-year-old woman with occult Gemella haemolysans bacteremia without a clear entry site. Gemella haemolysans is part of the normal human flora but can cause severe systemic infections such as infective endocarditis on rare occasions. In this patient, physical examination showed no localized symptoms, and a transthoracic echocardiogram showed no vegetation on the heart valves. The entry site for this pathogen was unclear. As the number of the elderly with asymptomatic infections has been increasing, clinicians should be aware of that this microorganism can cause occult bacteremia and infective endocarditis.
RESUMEN
BACKGROUND: There is no consensus regarding the best time to teach two fundamental pillars of clinical medicine: medical interview and physical examination. We investigated the impacts of teaching the course "Medical Interview and Physical Examination" in Japan from the very beginning of medical school. In addition, we also evaluated the educational value of using "Escape Rooms", a series of timed, game-based scenarios using simulators, as a part of the final assessment of the course. METHODS: At the end of the course, the interview capabilities of 140 first year medical students at International University of Health and Welfare (Japan) were assessed by physicians who acted as simulated patients. Physical examination skills were assessed using the "Escape Room" team task method. Students also self-assessed their confidence in their physical examination skills pre and post "Escape Rooms." A day prior to the final assessment, students completed an anonymous course evaluation. RESULTS: The average global rating of the students' medical interview skills using a rating scale from 1 to 6 (1-fail 6-outstanding, no different from practicing junior physician's level) was 4.6. Twenty-two students scored the highest mark of 6. An average of 89% of "Escape Room" teams finished all the physical examination tasks correctly within the allotted time. All teams that could not finish in time completed all tasks correctly when given an additional 3 to 5 min. Students' self-assessed confidence in their physical examination skills increased from 49 to 73 (out of 100) pre and post "Escape Rooms." In the course evaluation questionnaire, 99% of students answered "this course enhanced their motivation" (response rate 89%) and 99% also answered "this course was interesting and useful" (response rate 86%). CONCLUSIONS: This descriptive study analyzing both quantitative and qualitative data showed that the course not only achieved the intended objectives of successfully conducting comprehensive medical interview and basic physical examination skills, but also enhanced student motivation. "Escape Rooms", used for the course assessment, in itself enhanced students' self-perceived physical examination skills and had an added educational value.

BACKGROUND: Socratic method, which is an educational method to promote critical thinking through a dialogue, has never been practiced in a large number of people at the academic societies. METHODS: Modified Socratic method was performed for the first time as an educational seminar using an example case of moderate acute cholecystitis based on the evidence described in Tokyo Guidelines 2018. We adopted a method that Takada had been modifying for many years: the instructor first knows the degree of recognition of the audience, then the instructor gives a lecture in an easy-to-understand manner and receives questions from the audience, followed by repeated questions and answers toward a common recognition. RESULTS: Using slides, video, and an answer pad, 281 participants including the audience, instructors and moderators came together to repeatedly ask and answer questions in the five sessions related to the case scenario. The recognition rate of the topic of Critical View of Safety increased significantly before vs after this method (53.0% vs 90.3%). The seminar had been successfully performed by receiving a lot of praise from the participants. CONCLUSION: This educational method is considered to be adopted by many academic societies in the future as an effective educational method.

Nurse practitioners (NPs) provide medical care equivalent to that of physicians and facilitate access to healthcare. Although Japan's first NP graduated in 2010, how Japanese expert NPs work effectively in clinical contexts is yet to be investigated. We aimed to identify the competencies that make expert NPs in Japan effective. Twelve Japanese expert NPs were purposely selected. The average age of the participants was 44.8 years, average NP experience was 7.5 years, and eight participants were women. Semi-structured interviews were conducted online from March to May 2021. Interviews were recorded, transcribed verbatim, and analyzed using thematic analysis. Thematic analysis revealed five themes: working in physicians' contexts, interprofessional collaboration, involvement in nurses' work, contribution to healthcare, and personal qualities for effective working. Japanese expert NPs can function effectively in clinical settings by flexibly and humbly collaborating with other medical professionals who have autonomous positions. They can improve the quality of healthcare by proposing practical solutions to problems faced by patients and medical organizations. These explored competencies can be applied to other aging and more complex societal contexts, and in updating the required competencies of Japanese NPs.
RESUMEN
PURPOSE: Health science students need to be professional to improve quality of care (QOC) in the current Vietnamese healthcare system. Therefore, we aim to evaluate medicine and traditional medicine (TM) students' perception of the professional attributes relating to QOC for improving inter-disciplined professionalism training that promotes QOC in Vietnam. METHODS: The cross-sectional study was carried on 2039 students of 6 years at the University of Medicine and Pharmacy at Ho Chi Minh City (HUMP) from the medical and TM faculty in March, 2021. The Vietnamese American Board of Internal Medicine (ABIM) questionnaire (2011) was used as the survey instrument. The confirmatory factor analysis (CFA) was performed to confirm the validity of the scale in TM students. Mean, Min-Max, standard deviation and sample paired t-test were performed for Likert scale. The one-way ANOVA was used for inferential statistics. RESULTS: The CFA demonstrated the validity of the Vietnamese questionnaire in measuring 4 QOC-relating professional attributes, previously found in medical students for TM students. In both faculties and across academic years, students perceived self-awareness and ensuring QOC as the leading important attribute, while social duty and professional habit as the least important attribute. Contrasting with preclinical phase, students' perception did not differ significantly between the two faculties in their clinical years (p > 0.05). CONCLUSION: TM students share universal QOC-relating professional traits with medical students. Moreover, exposure to clinical environment might increase inter-disciplined agreement on importance of these attributes. However, health sciences students' underestimation of social duty and professional habit persists throughout 6 academic years. Hidden curriculum in clinical training such as specialist-centeredness might hinder the students' improvement in perception of these traits. Therefore, these traits should strongly be emphasized in professionalism training to decrease the effects of hidden curriculum on them.
RESUMEN
We report the case of a 71-year-old Japanese man with a history of chronic kidney disease and sarcoidosis receiving chronic corticosteroids who presented with disseminated Nocardia brasiliensis infection. He initially showed improvement with empiric antimicrobial therapy including trimethoprim-sulfamethoxazole. However, he deteriorated after modifying the empiric regimen due to complicated hyperkalemia and ultimately died. In general, elderly patients have decreased renal function. Standard therapy for nocardiosis with trimethoprim-sulfamethoxazole may not be used for a prolonged period of time. This case emphasizes the challenges and importance of prudent selection of empiric antimicrobial therapy for disseminated nocardiosis in elderly patients with underlying kidney disease.
RESUMEN
Acute hepatitis A is caused by hepatitis A virus (HAV), which spreads through contaminated food or water or person-to-person contact, and has been epidemic among men who have sex with men (MSM) since 2018 in Tokyo. The majority of these patients have been found to be seropositive for human immunodeficiency virus (HIV) and contracted hepatitis A through sexual contact. We cared for an HIV-positive patient with fulminant hepatitis A while on antiretroviral therapy at our hospital. Hepatitis A vaccine should be aggressively promoted for HIV-positive MSM.

Human papillomavirus vaccination (HPVV) was included in the national immunization program in 2013 in Japan. However, the Japanese government suspended proactive recommendations 2 months after this decision because various adverse events following the vaccination were reported by the media. More than 6 years have already passed since the suspension of proactive recommendations of all available vaccines in Japan. Although no causal relationship between the adverse effects and HPVV has been confirmed, the Japanese government has not withdrawn the suspension. Thus, it is important to show various possible causes of the adverse events other than HPVV. It is attempted to describe the possible contribution of the misunderstanding regarding the symptoms of postural tachycardia syndrome, deconditioning, and exercise-induced hyperalgesia as the adverse effects of HPVV in this review article.

An 81-year-old Japanese man with no history of diabetes mellitus was admitted to our hospital for a fever with a new ulcerative lesion on the left heel. Blood cultures on admission grew Arcanobacterium haemolyticum in aerobic bottles. He was therefore diagnosed with A. haemolyticum bacteremia and osteomyelitis complicated with foot decubitus ulcer. He was successfully treated with intravenous antibiotic therapy and debridement of the left heel. Our case and literature review show that it is important to recognize that A. haemolyticum is a systemic causative pathogen in immunocompetent patients in primary care practice.

A 52-year-old Japanese man with a history of type 2 diabetes mellitus (DM) presented with mild dizziness. On admission, the physical examination only revealed tachycardia and right sided cervical lymphadenopathy. On the fifth day of admission, his mental status slightly worsened. Urgent Computed Tomography (CT) of the head and neck revealed multiple abscesses spreading from the right temporal bone to the right sternocleidomastoid muscle. Bezold's abscess was diagnosed. Streptococcus pneumoniae was isolated from middle ear fluid and blood cultures. Bezold's abscess has rarely been described in the era of antimicrobial therapy. However this abscess can still occur in patients without any typical severe symptoms. Repeated history taking and thorough physical examination can help detect Bezold's abscess.
