Governor’s Message

This is the time of year to remind you of our Chapter Meeting in June. We are going to hold the meeting remotely for the first time. The all-virtual meetings have some disadvantages in some aspect but at the same time there are advantages as well – even busy doctors can participate in the meetings from their offices without travelling so far. The planning team of the Scientific Program Committee led by Dr. Sugihiro Hamaguchi has put together a great agenda. I am excited to welcome our members to the meeting.

The ACP annual meeting in the USA, Internal Medicine Meeting 2021 (IMM2021), took place the other day in the virtual style and it went successfully. Although there were some challenges for us because of time difference between USA and Japan, it was a wonderful meeting. I personally enjoyed “Thieves’ Market” by Dr. David Scrase. Cases were presented in fun and interactive session. This event will be introduced to Japan for the first time in the next Japan Chapter meeting in June. I hope all of you will enjoy!

Congratulations new fellows and masters! To follow are the pictures from the IMM2021. It’s a pity that we couldn’t do marching in the venue but it was a proud moment.

The Physicians’ Well-being Team of our Chapter conducted a questionnaire survey in March and reported that 69 (30.9%) among 223 respondents had burnt out as of the survey. The survey also found that 79 (35.4%) and 78 (35.0%) reported insomniac symptoms and anxiety, respectively, whilst 33 (14.8%) were depressed. Approximately 40% of the respondents considered changing their job responsibilities in the COVID-19 pandemic. I hope all the stress will be dispersed with weathering the coronavirus crisis.

It has been two years since I became a Governor and now it’s time to select the next Governor (Governor-Elect). I know that both of the two candidates are excellent persons and each deserves to be a governor. I hope all the members will join in the fair voting.

Stay well and enjoy your spring and summer!

The 2nd MKSAP study session

The Resident Fellow Committee (RFC) of the American College of Physicians (ACP) Japan Chapter held their second MKSAP study session on Sunday, April 18, 2021. This session, utilizing ACP’s famous online learning tool MKSAP, is approved by ACP Headquarters. Dr. Yuji Yamada (Department of Geriatrics and Palliative Medicine, The Mount Sinai Hospital) was invited for this session with the theme of “Hematology”, and he explained five pre-selected questions from MKSAP. We had a lively study session, with participants answering each question and many more questions flying in the chat box.

The 1st question was about the “treatment of iron deficiency anemia,” and Dr. Yamada gave an in-depth explanation of common problems we encounter in our daily clinical practice.

The 2nd question was about “how to deal with poor INR control associated with warfarin usage”. Recently, DOACs are being used more frequently, and the occasions for prescribing warfarin are decreasing, but this is still a problem we encounter often. The lecture was full of useful tips for tomorrow’s practice, such as the differentiation of various anticoagulants.

The 3rd question was about the “diagnosis of polycythemia vera.” Dr. Yamada provided a clear explanation utilizing a diagnosis flowchart style, and we were able to hear Dr. Yamada’s personal experience where changes in lab data led to the diagnosis of a new hidden disease.

The 4th and 5th questions were about “HIT (heparin-induced thrombocytopenia)” and “DIHA (drug-induced hemolytic anemia)”. We discussed their differences and what to look out for in these diseases. We may know these diseases as medical knowledge but feel uneasy about actually clinically managing them. We also studied a wide range of topics, including the introduction of VITT (Vaccine-induced Immune Thrombocytopenia), a new finding that has become a hot topic with the new coronavirus vaccine.

This MKSAP study session was also a time to increase motivation for daily study. Dr. Yamada carefully explained important points in actual clinical management, including common pitfalls. He taught us in a way that is easy for non-specialists to understand, while mixing in his expertise and advanced viewpoint.

RFC will continue to hold events, including this study session, to improve our daily practice. In addition, we will provide a platform for those who want to go abroad. The ACP Japan Chapter Annual Meeting is scheduled to be held, for the first time online, on June 26 and 27, 2021. The next MKSAP workshop is scheduled to be held in August or September after the Annual Meeting. We look forward to seeing you at our ACP Annual Meeting and at one of our many study sessions.

第2回MKSAP 厳選5題 -Training with Specialist-

米国内科学会(ACP)日本支部の若手医師部会(Resident Fellow Committee:RFC)は、2021年4月18日(日)にACP本部公認のMKSAP勉強会を開催いたしました。

第2回となる今回は「血液内科」領域をテーマに山田 悠史先生(マウントサイナイ医科大学 老年医学・緩和医療科)をお招きし、MKSAPより厳選した5題を解説いただきました。当日は、1問ごとに参加者が回答、チャットボックスには質問が飛び交う、活発な勉強会となりました。

第1問は「鉄欠乏性貧血の治療」について、日常臨床でよく出会うプロブレムを病態から掘り下げて解説いただきました。Common diseaseということもあり、多くの時間を割いたこの問題では、鉄動態に重要なヘプシジンに関連した新薬が生まれつつあるという最新の知識に触れ、病態に立ち戻ることの大切さを考えさせられました。



第4、5問は「HIT(ヘパリン起因性血小板減少症)」「DIHA(薬剤性溶血性貧血)」に関する問題でした。知識としては知っていても、実際のマネジメントには不安を覚える疾患について、鑑別や考えるべきことをまとめて話していただきました。また、新型コロナウイルスワクチンで話題となった新しい知見「VITT(Vaccine-induced Immune Thrombotic Thrombocytopenia)」の紹介を含めて幅広く解説していただきました。

The Resident Fellow Committee (RFC) of the American College of Physicians (ACP) Japan Chapter held a MKSAP study session on February 17, 2021. This new project was made a regular series because of its high popularity, as seen in the results of last RFC seminar’s survey. An expert in the field of internal medicine was invited, and each of the five pre-selected problems were explained in detail by RFC members. The purpose of this series is to learn the latest clinical knowledge from frontline experts through MKSAP’s high quality problems and enhance our knowledge of each internal medicine field in a short amount of time. We plan on holding this seminar series every few months.

For this session, we invited Dr. Jun Kataoka (Department of General Emergency Medicine and Intensive Care Unit, Nerimahikarigaoka Hospital) to talk about “Respiratory and Intensive Care”.

For the first and second question, he explained in detail using slides: the indications for intubation in acute respiratory failure, and the treatment of ARDS. Personally, even if I could choose the best treatment option, I have always found it difficult to explain why that particular treatment is effective. Dr. Kataoka’s concise and clear explanations with regard to respiratory physiology and ground-breaking research, helped deepen my understanding.

The third question was about different types of pleural effusion. We tend to treat pleural effusion without much thought because it is a condition that we routinely encounter in the medical setting. However, by reviewing the condition’s definition and categorization, I managed to improve my understanding. I found the clinical experience-based explanation on indications and pitfalls of pleural effusion drainage to be especially memorable.

The fourth question was about treatment methods for severe acute exacerbations of asthma. I felt the differentiation of these drugs in clinical practice is directly relevant to how we treat these patients daily. As a related topic, he also touched on the latest treatment for chronic management of asthma, which further expanded my knowledge.

The last question was about the treatment of COPD with repeated acute exacerbations. What I found most interesting was the relationship between the patient’s eosinophil count and the efficacy of ICS for patients with COPD. We were able to see the thought process behind choosing which patients to put on ICS, as well as how to take into account eosinophil count and asthma comorbidity. It was a very meaningful and helpful topic to learn about.

RFC will continue to hold events, including this study session, to improve our daily medical practice. In addition, we will continue to provide a platform for those who want to practice abroad. As mentioned in the previous newsletter, the ACP Japan Chapter Annual Meeting will be held, for the first time online, in June 2021. If you are interested, please join us.

Women’s Committee

American College of Physicians Japan Chapter Interim Report 2020

Women’s Committee

Chair: Noriko Yamamoto MD, FACP

Report: What we have done:

The Women’s Committee has 10 members including 4 male members. We started out with 6 female members from 2017 July. I am pleased to increase the male members. That’s because the female members don’t know how the male physicians feel about something female physicians work and struggle. And when the male members talk about their confusion to attend some problem with female physicians on our mailing list, female members notice their confusion and find their own problems and other obstacles .I think it’s important that such a mutual understanding keep going for long time, moreover the male and female physicians will get to sympathize each other.

Session Plan:

This June we couldn’t hold the annual session of Japan Chapter, we have a plan to hold the session at next annual meeting. We collaborate with the Physician’s Well-Being Team and have a plan to hold the work shop about physician ‘s Burn-out.

Facebook Page

  We have the Facebook page. We post the news and articles of ACP and other information, news about gender inequity.

Woman in Medicine Month (September)

We recommended a FACP from women’s members on September, Dr. Naoko Iwasaki MD.

Plan: What we are going to:

  We will hold the session about communications at the workplace next meeting. We are making the details of this session concretely. We collaborate with the Physicians Well-Being Team; we might have the workshop about physician’s Burn-out and coaching next year except annual meeting. I want to increase more female FACPs in Japan Chapter. I wish many female physicians will have activities in ACP Japan Chapter vividly, I will recruit some members for Women’s Committee next term.
