Winner of Dr’s Dilemma

Shogo Shirota

Tochigi Medical Center

I am honored to report that Dr. Kawaguchi and I won the first prize in the American College of Physicians (ACP) Doctor’s Dilemma competition 2019.

I have participated in ACP Japan Chapter(JC) since I was a medical student. Each year, I took a lot of interesting and interactive workshops, and got to know many outstanding medical students and doctors. Doctor’s Dilemma is one of the most interesting program, but I could not take part in it, because I was not able to get a partner.

There were the largest number, 35, of participating teams from various hospitals this year. In the Preliminary, we used smartphones to answer multiple choice questions. The questions are not so difficult, which made us nervous because losing even one question would be critical. We got 6th place and cleared the Preliminary.

The Final started after two-hour break. There were buzzer quiz at first, then more difficult, multiple choice questions from every areas of internal medicine. It was difficult to get point at first, because other team pressed the buzzer while we are discussing whether our answer was absolutely correct. Once we were able to select the multiple choice questions that every team had the right to answer but lost points with each incorrect answer, we could get almost all of the answers right. They were questions that were directly connected to what we do every day, and some of them we knew from MKSAP. That’s how we won the championship.

There are several reasons why we won this year. In addition to working up many MKSAP questions by ourselves, we see a variety of patients every day as a GIM physician. Moreover, we have various kinds of study sessions in our hospital which vary from day to day. These include clinical reasoning conference, learning how to make clinical question and search for it, introducing several papers in a short time, and so on. They made us deepen our medical knowledge very efficiently.

Finally, I would like to express my heartfelt gratitude to the attending doctors who mentored us, the colleagues and friends who congratulated us, and every staff who helped holding the ACP Japan chapter.

ACP日本支部総会2019 Dr’s Dilemma優勝者のことば

この度、京都大学で開催されたACP JC年次総会2019のDr’s Dilemmaにおいて、優勝させていただきましたのでご報告致します。

私は学生の頃からACP JCに参加しており、毎年様々なレクチャーやワークショップに参加して新しいことを学んだり、同じように頑張っている仲間に出会い刺激を受けていました。Dr’s Dilemmaはいつも楽しみにしていた企画ではありましたが、なかなか相方がいなかったので、今回が初参加でした。




日々我々を教育してくださった指導医の方々に改めて感謝申し上げます。また、このような貴重な機会をいただくことができましたACP 日本支部の諸先生方に感謝を申し上げ、優勝報告といたします。



Winner of Kurokawa Prize in Students section

Comments on receiving the Kurokawa Prize (Medical Student branch) at the ACP Japan Chapter Annual Meeting 2019


Medical Student, Juntendo University School of Medicine

I am very honored to be awarded the Kurokawa Prize at the American College of Physicians (ACP) Japan Chapter Annual Meeting 2019 in Kyoto.


At the meeting, I made a presentation entitled “Unaware of glaucoma and traffic accidents: a proposal to detect visual field defects by CLOCK CHART”. I presented this issue, because I believe that it is clinically and socially significant for us to screen for glaucoma using CLOCK CHART, considering that this pathological condition is related to traffic accidents.


One of main research themes at the Department of Public Health, Juntendo University, is “health-related traffic accidents”, which include the effects of obstructive sleep apnea, hay fever and glaucoma. Among these, the prevalence of glaucoma is around 5% for those aged 40 years and over in Japan, whereas 90 percent of those affected are not aware of their disorder and remain untreated. Numerous previous studies reported the association between glaucoma and traffic accidents. Thus, there will be many latent patients with glaucoma who need appropriate diagnosis and treatment.


To address this, I collected 5 cases with glaucoma and examined their visual fields using both a Humphrey Field Analyzer and CLOCK CHART, the latter of which is a handy visual field screening tool. I found that the agreement rate between the Humphrey Field Analyzer and CLOCK CHART was substantially high. Therefore, it is concluded that screening visual fields using CLOCK CHART by general physicians would enhance the detection of glaucoma, leading to its early diagnosis and treatment, and reducing “health-related traffic accidents”.


I am also on a team investigating over 2000 commercial drivers. While still in progress, we are now analyzing the inter-relationships between traffic accidents and visual field defects detected by CLOCK CHART.

Finally, I would like to express my gratitude to Professor Tanigawa, Dr. Wada and all other teachers for their kind advice.

I am grateful that I could receive the Kurokawa Prize in the Annual Meeting of ACP Japan 2019. The basic idea of our study “Japanese people tend to overestimate their future cardiovascular risk” originated from the question, “aren’t people unnecessary worried about developing cardiovascular disease (CVD)?” In Japan, the risk of developing CVD in a patient with a slightly elevated LDL cholesterol is relatively low, in most cases, only a few percent in 10 years. Our impression was that people seem to be much more worried about developing CVD.


In our study, we could show that patients undergoing routine health check-up in our center significantly overestimated their risk of developing cardiovascular disease. Patients estimated their 10-year CVD risk as around 30%, compared with the calculated risk of 3%. From this result, we can make a hypothesis that CVD risk management in Japan may be conducted based on this misunderstanding.


We are planning for further research on this field. Will this misunderstanding affect the patient’s health seeking behavior, satisfaction, outcome, and will there be a positive effect of correcting this misunderstanding?


I would like to thank my boss, Dr. Eiji Hiraoka for supporting the whole work, and I would also like to thank all the people who were responsible for preparing this meeting.

東京ベイ・浦安市川医療センター 総合内科 松尾裕一郎



この度は、栄誉ある黒川賞をいただき、大変光栄に思います。今回の私達の研究「健康診断を受診する患者は、自身の心血管病リスクを過大評価する」は、私達が普段の外来診療で感じていた疑問、違和感を検証したものです。健康診断では、一般にLDLコレステロールが120mg/dLを超えると「軽度の異常」という判定になります。では実際に、それらの患者がその後10年でどのくらいの確率で心血管病を発症するかというと、問題が軽度の高LDL血症だけであれば数%以下程度です。しかしながら、患者自身はリスクがもっと高いと考えており、心血管病発症を必要以上に心配しているのではないか?というのが私達の疑問です。結果は私達の予想通り、Suita Scoreにより計算される患者の心血管病リスクは3%程度であるのに対し、患者自身が予測するリスクは30%程度である、というものでした。このことから、日本における脂質異常症などの生活習慣病診療が、患者の誤解のもとに行われている可能性、自身のリスクについて医療者と話をする機会の無い患者が、不必要な不安を抱えている可能性などを、間接的に示すことができたと考えています。





Dr. Mai Okamoto, Winner of Kurokawa Prize in Resident/Fellow section

I am very honored to receive the Kurokawa Prize at the ACP Japan 2019. I greatly appreciate the support of attending doctors.


History of research

I have been interested in the appropriate antibiotics in my medical student days, but It was different from what I imagine in clinical settings. One of the reasons was that it needs several days to identify bacteria from specimens. Although the antimicrobial agent is determined on the assumption of the microbes, it does not always proceed as expected. In some cases, empirical treatment has failed to cover, on the other hand, I tended to use inappropriate broad-spectrum antibiotics.


The turning point of research

In July 2018, when I was the second year of residency, “FilmArray multiplex PCR” was introduced in our hospital. This machine can identify bacteria in the blood more rapidly than the conventional method. When the blood culture becomes positive, the FilmArray can detect in about one hour. This system has already been introduced abroad, and some studies have shown efficacy for antimicrobial stewardship. There are few experiences in our country and the microbiology laboratory setting is different from that high volume centers in prior reports. So, I decided to examine the change in the usage of antimicrobial agents before and after introducing FilmArray system.


Future expectations

This study showed that the time to start anti-MRSA drug for MRSA was shortened, and furthermore, 28-days overall survival was improved in the Gram-positive cocci baceteremia group by using FilmArray. The improvement of the survival rate is different from the prior studies, and it is considered that further study is necessary. However, our study suggested that the use of FilmArray may help the appropriate use of antibacterial agents. We hope further research will progress and would like to contribute to ASPs.
