Kurokawa Award (Case Report Category) Recipient’s Remarks

Junji Sunakawa, MD

Okinawa Miyako Hospital

I am honored to receive the Kurokawa Award at the American College of Physicians Japan Chapter Annual Meeting 2023.

I presented the case report titled “Spontaneous bladder rupture with profound hyponatremia and pseudo-renal failure”. Spontaneous bladder rupture is uncommon and there are few case reports that lead to profound hyponatremia. We repeatedly discussed from the perspective of pathophysiology why severe hyponatremia occurred in this case. I realized that the learning points became clear when I imagined how I would teach residents.

This was my first time to present a case report in English. Dr. Kiyoshi Kinjo gave me a lot of guidance. I would like to take this opportunity to thank Dr. Kinjo and my colleagues who worked very hard with me on this difficult case.

As a doctor who works on a remote island, it is my important job to share interesting cases that are unique to remote islands. I will continue studying and working hard to grow my skills as a good clinical educator.

Finally, I would like to express my appreciation to everyone involved in the ACP Japan Annual Meeting 2023.

Kurokawa Award (Clinical Research Category) Recipient’s Remarks

Yoko Nishizawa, M.D., Ph.D., M.P.H.

Teikyo University Graduate School of Public Health

I am honored to receive the Kurokawa Award at the ACP Japan Chapter Annual Meeting 2023.

At the meeting, I presented our study entitled “Loneliness Is Associated with Low-Health Interest: A Nationwide Cross-Sectional Study”. Our study used a Japanese nationwide questionnaire survey and showed that people who feel loneliness were less interested in their health. Recently, loneliness is reported to be associated with various diseases and mortality. Moreover, health interest is associated with disease prevention or treatment behaviors. We were not able to detect causality in our present study, however, we intend to conduct further research on the theme of loneliness and health.

I have worked as a nephrologist, and I have done a few clinical researches on chronic kidney diseases. While doing my researches, I noticed the importance of study design and epidemiology. I am now studying at a graduate school of public health. Receiving this award is encouraging my carrier and maintaining motivation. I am deeply gratified about this award. Thank you so much.

Research cannot be done by one single person, but requires the cooperation of many different specialists to make it better. I would like to express my gratefulness for enabling me to receive this award. I appreciate Dr. Takahiro Tabuchi of the Osaka International Cancer Center for providing the data, and Dr. Yoshiharu Fukuda of Teikyo University Graduate School of Public Health for his guidance, and all those who involved to our study. Finally, I would like to express my sincere gratitude to the American College of Physicians Japan Chapter for organizing and supporting this conference.

今回、“Loneliness Is Associated with Low-Health Interest: A Nationwide Cross-Sectional Study”というタイトルで発表させていただきました。全国規模のアンケート調査を分析したところ,孤独を感じている人は健康への関心が低くなるという結果でした。孤独はさまざまな疾患と関連し,さらには死亡率とも関連することが分かってきています。また,健康への関心は疾病予防行動や受療行動と関連することが明らかになっています。今回の研究で孤独と健康への関心について因果関係にまで言及することは困難ですが,さらなる研究を行っていければと考えています。



Internal Medicine Meeting 2023 Doctor’s Dilemma体験レポート(2)


福島県立医科大学附属病院の松崎史弥先生から、Internal Medicine Meeting 2023 Doctor’s Dilemmaの体験レポートを頂きましたのでご報告いたします。

この度、私は米国内科学会総会にてDoctor’s Dilemmaの日本代表として参加させていただきました。日本代表としての参加は光栄でしたが、望んだ成績を収めることができず、申し訳ありませんでした。早押しに勝つことができず、英語力不足を痛感いたしました。



I had the honor of participating as the representative for Japan in the Doctor’s Dilemma at the annual meeting of the American College of Physicians. Although it was a great privilege to represent Japan, I apologize for not achieving the desired results. I realized my lack of English proficiency as I was unable to win in the quick response rounds.

The conference provided me with a valuable experience to share the latest research and topics in internal medicine. Through exhibitions and demonstrations of the latest medical devices and digital tools, I learned how these innovative tools are being utilized in clinical settings. I also had the opportunity to interact with graduate students and physicians who are actively involved in the field in the United States, which was highly inspiring. I aim to improve my English skills and continue participating in such conferences and strive to deliver achievements like yours in the future.

Lastly, I would like to express my sincere gratitude to all the members of the Japanese Chapter of the American College of Physicians who gave me this wonderful opportunity. I would also like to thank you for the financial support provided for my travel expenses. Thank you very much indeed.

Internal Medicine Meeting 2023 Doctor’s Dilemma体験レポート(1)


福島県立医科大学附属病院の佐々木 庸輔先生から、Internal Medicine Meeting 2023 Doctor’s Dilemmaの体験レポートを頂きましたのでご報告いたします。

この度2023年4月にサンディエゴにて開催された米国内科学会のDoctor’s dilemmaに挑戦させていただきました,福島県立医科大学附属病院総合内科専攻医の佐々木 庸輔と申します.



Doctor’s dilemmaは早押しクイズ形式で行われ,司会者がまず問題文を読み上げ,回答権を勝ち取ったチームが回答を口述するというものでした.司会者が問題文を述べ終えてから問題文がモニターに提示されるため,英語のリスニング力が当然の如く試されました.一瞬の逡巡も許されぬスピーディ-な熱戦が繰り広げられていましたが,その雰囲気に呑まれて唖然としているうちにあっという間に終わってしまったというのが正直なところです.皆様のご期待に沿えず,準決勝に進出することはできませんでした. 難しい問題もありましたが,今回の主たる敗因は,紛れもなく「言語の壁」であったと感じています.




My name is Yosuke Sasaki, and I am a resident doctor in the Department of General Internal Medicine at Fukushima Medical University Hospital.

In the preliminary round of the Japan Chapter Congress that I participated in as an initial resident in 2021, I won second place and earned the right to participate in the Congress. I had initially planned to participate in the 2022 main competition, but I had to give up my participation in tears due to concerns about the COVID-19 pandemic. However, thanks to the special arrangement of the ACP Japan Chapter and the headquarters, we could participate as a three-member team with senior members of our department who won the championship in 2022.

I confess that I was anxious and nervous because it was my first time traveling abroad. But all the members of the Japan Chapter warmly greeted me, which encouraged me a lot.

The dilemma was conducted in a quick push quiz format, with the moderator reading the questions first and the team that won the right to answer dictating the answers. The questions were presented on the monitor after the moderator had finished reading the questions, so Listening skills are required as a matter of course. The speedy and heated competition, in which not even a moment’s hesitation was allowed, ended in a blink of an eye, and I was stunned by the atmosphere. Eventually, we could not make it to the semi-finals in the quiz competition. I think one of the primary reasons for the loss is the “language barrier.”

I was inspired by an American physician’s passion for internal medicine and impressed by their extensive knowledge and warm-heartedness. I always felt frustrated because I could not communicate with local people in English as much as I wanted to. These experiences have motivated me to learn not only medicine but also English, which will be necessary for my future growth as a physician and have significantly broadened my narrow perspective as a physician. In other words, the biggest takeaway from this trip was that I recognized the importance of having a global perspective as a Japanese physician. Learning English is indispensable to absorbing medical knowledge in depth and breadth. Therefore, after returning to Japan, I have been improving my English daily.

I am grateful to all the members of the Japan Chapter for giving me valuable opportunities and subsidizing my travel expenses. I am truly honored to be a member of the ACP and look forward to continuing my journey as a physician. Soon, I hope to return to the United States to compete once again.

Internal Medicine Meeting 2023ポスター発表体験レポート(2)


ACP日本支部年次総会・講演会2022 黒川賞(学生部門)を受賞して国立国際医療研究センターの岩田 純奈先生から、Internal Medicine Meeting 2023ポスター発表の体験レポートを頂きましたのでご報告いたします。

この度、2023年4月27日から29日にアメリカ・サンディエゴで開催された、米国内科学会総会2023 のNational Abstract Competitionに参加させていただきました。

米国内科学会日本支部総会2022においてMedical Student部門の黒川賞をいただいたため、米国内科学会総会での発表を日本支部よりご支援いただきました。私にとっては初めての現地での学会であり、それがさらに海外であることから当初は不安が大きかったのですが、抄録の登録から渡航まで日本支部の先生方やスタッフの皆様に旅費も含めた多くのサポートを受け、私の初の海外学会発表が実現しました。


発表自体はあっという間に終わってしまいましたが、発表の時間以外にも学会を目一杯満喫することができました。医学生や若手医師向けの講演に参加したり、ベッドサイドのスキルを学ぶスキルスセンターで実際に身体診察の練習をしたり、また大変優秀なInternational medical graduateと交流を行ったりなど、短い時間ではありましたが、刺激的で興味深い経験を積むことができました。日本では研修医生活がはじまったばかりというタイミングだったので、自分が今後どのようなキャリアを積むべきかを考えるきっかけとなりましたし、米国や日本で活躍されているロールモデルとなる先生方にも出会うことができ、まさにLife Changing Experienceになりました。この経験を活かして、今後も精進して参ります。



I participated in the National Abstract Competition of the Internal Medicine Meeting 2023 held in San Diego, U.S., from April 27 to 29, 2023.

As I received the Kurokawa Award in the Medical Student category at the American College of Physician Japan Chapter Meeting 2022, the Japanese Chapter supported me to have a poster presentation at the Internal Medicine Meeting 2023. I was initially very anxious because it would be my first on-site academic conference, and even more so because it would be held abroad. However, I received a lot of support, including financial support, from the physicians and staff of the Japan Chapter, from abstract registration to travel fees, and my first presentation at the conference in the U.S.  was realized.

I gave a poster presentation on the morning of April 29 (local time). The theme was ” The perceptions of overseas experiences among medical students in Japan: a national, online survey”, which summarized the responses from 548 Japanese medical students about how interested they were in studying and working abroad. On the day of the presentation, I was almost put off by the high quality of the poster presentations by U.S. medical students around me. Nevertheless, I was able to present with confident in front of the three judges and the Japanese participants who visited me to listen to my presentation. I was relieved that the judges listened to my presentation and asked me questions with their interest, even though my research targeted Japanese medical students.

Although the presentation itself was over in a flash, I was able to fully enjoy various contents at the conference. I attended many lectures for medical students and young doctors, practiced physical examination at the Skills Center where I learned bedside skills, and interacted with very talented international medical graduates. Every moment at the conference was an interesting and stimulating experience. Since I had just started my junior residency in Japan, it gave me a chance to think about what kind of career I would like to pursue in the future. Moreover, I met role models who actively work as a physician in the U.S. and Japan. It was truly a life-changing experience, and I will continue to make the most of this experience.

Finally, I would like to thank the American College of Physicians Japan Chapter and for supporting my presentation at IM2023.

ACP日本支部年次総会・講演会2022 黒川賞(若手医師部門)を受賞してマウント・サイナイ・アイカーン医科大学の原田 洸先生から、Internal Medicine Meeting 2023ポスター発表の体験レポートを頂きましたのでご報告いたします。






I am pleased to announce my participation in the annual meeting of the American College of Physicians (ACP) in 2023. I would like to express my gratitude for the travel support from the ACP Japan Chapter that made this participation possible.

At the conference, I presented a poster that was selected for the Japan Chapter Award, detailing the trends in sarcoidosis mortality rates in Japan. We analyzed sarcoidosis-related mortality in Japan over the past 20 years among the older population, which revealed an increase in sarcoidosis related mortality rate, especially in the older population with a female predominance. Sarcoidosis has been attracting increasing attention recently, and the poster presentation drew the interest of many participants, leading to a meaningful Q&A session.

I have attended several international medical conferences previously, and I noticed that the ACP conferences are distinguished by their sophisticated lectures. The speakers were all excellent, focusing on important topics for internists in their talks and slides, allowing me to learn content that will be useful from the next day of the conference. The lecture addressing the issues within the U.S. insurance system was especially intriguing. The U.S. medical insurance system is highly complex, representing one of the major differences between Japanese and U.S. healthcare. This was an excellent opportunity for me to contemplate the ideal medical insurance system.

The conference was a valuable platform for information exchange, where I was able to gain new knowledge from experts around the world and share my own research widely. I plan to continue actively participating in ACP Japan Chapter conferences and the annual ACP conferences, and will strive to contribute to the advancement of the ACP Japan Chapter. Finally, I would like to extend my thanks once again to all those involved in the ACP Japan Chapter for providing this wonderful experience.

New Governor’s Statement

I succeeded Governor Kenji Maeda as of April 29, 2023, and have been appointed the 5th Governor of the Japan Chapter of the American College of Physicians. The COVID-19 pandemic has almost ended, and the new post-COVID-19 era has begun. As the Governor, I have three objectives that I aim to accomplish during the next four years. First, I would like to promote more diversity in this chapter as well as within the country at large. Secondly, I would like to promote evidence-based preventive medicine, including cancer screening and adult vaccination programs. Thirdly, I would like to promote evidence-based education for health professionals which seamlessly links the undergraduate, postgraduate, and continuing professional development stages.

Allow me to explain these three objectives in more detail.

1.Promoting diversity

I shall be including more medical students, residents/fellows, and early-career physicians and women to the Governor Advisory Committee in order to incorporate a broader perspective with which to navigate the chapter. In addition, in the era of Well-being 2.0, we will be promoting the health and well-being of physicians from an organizational standpoint.

2.Promoting evidence-based preventive medicine

In order to pursue this goal, the Preventive Medicine Task Force Committee was established, and began its activities this year. This task force shall promote evidence-based preventative medicine as an academic society by delivering recommendations to clinicians.

3.Promoting evidence-based education to health professions

I will promote seamless evidence-based education for healthcare professionals that seamlessly link the undergraduate, postgraduate, and continuing professional development stages. As part of this education, we will promote international collaboration between ACP members in Japan and abroad in order to share wisdom and realize better patient care. Another project includes the “Rising Star Scholarship Program.” This scholarship program will be launched this year to support early career residents in Internal Medicine.

We look forward to the continued support of all Members, Fellows, and Masters, as we strive to overcome the 3Gs (Gender, Generation, Geography) gap which is a major challenge in Japan, and to achieve the 3Es (Equitable, Enjoyable, and Empowering) within the organization. I truly appreciate your understanding and cooperation in advance.
