A visit to RTIC and Ta Nao Si Health Center.

On March 27th, I was able to visit Rajanagarindra Tropical Disease International Centre (RTIC) and Ta Nao Si Health Center, in Suan Phueng district, Ratchaburi province, near Thailand's western border with Burma (Myanmar).

How did it happen? Well, a very good old friend of mine from my high school days in Maryland, U.S. took me there. He was one of my best friends there, but an year after I returned to Japan he also needed to go back to his home country, Thailand, and as our lives got busier, our emails became sporadic. However, as our lives progressed, so did information technology, and one day he invited me to Facebook, a social networking service (SNS) which is especially popular among university students in the U.S. with well over 85% of them being members. We've been in close touch ever since, and I had a chance to see him this spring for the first time in nine years.

He majored in public health and epidemiology in university, and as that implies, shares a lot of common interests with me. We could go on talking for hours and hours, until our tongues became numb. And... he is also a humanitarian junkie. He's a highly-motivated, passionate, yet kind and thoughtful person who always used to talk about how he wanted to do good for his country and its people. So well, when I asked him if I could take a peek at some places he know that can be visited during my time frame there, he happily offered me to take me here.

RTIC, or the Suan Phueng Research Unit, run by Mahidol University's Faculty of Tropical Medicine and supported by the Tropical Disease Trust Fund under the Princess Galyani Vadhana, is one of the faculty's research stations for conducting research on tropical diseases. The facility's primary activities are (1) provision of health services (especially against infectious diseases) for the local people, (2) field epidemiology training for students from not only the faculty but from other countries as well, including Cambodia, Vietnam, Laos, and Burma, and (3) research of infectious diseases (mainly malaria) in the area.

Suan Phueng is a small district in Ratchaburi Province, located on the border with Burma, which is just a 15-minute drive from RTIC. It has an area of 2,545 square kilometers, consists of seven sub-districts with 8,254 households and a population of 66,972. Over 90% of the population are mainly Thai-Karen of low socio-economic status, some of who do not carry Thai identity cards. Along with 13 health centers, they also have a community hospital with 30 beds, about 30 minutes from RTIC. Common health issues of the people living in this area include malaria, dengue hemorrhagic fever (DHF), filariasis, tropical skin diseases, intestinal helminthiasis, and malnutrition.

When we visited, Dr. Maneeboonyang of Mahidol University was on duty at RTIC and he happily welcomed us and gave a brief tour of the center. According to him, this area has the highest prevalence of malaria in Thailand at around 12-13%. The kingdom is one of only a handful of countries that have succeeded in eliminating and controlling this notorious mosquito-borne disease, however, it still remains a big issue along the border with Burma. But still, the situation has been improving, since prevalence was around 30% only a decade ago, with at least one person in every single household having malaria in one of the hamlets. According to Dr. Maneeboonyang, RTIC sees 10 patients per day in the dry season (January - April) and over 30 during the rainy season, and out of that, about two and six people are diagnosed with malaria, respectively.

After the tour, he was kind enough to take us to Ta Nao Si Health Center, which is one of 13 health centers in Suan Phueng district. It provides primary medical care, immunization, and antenatal care for the local residents. We had a chance to have a short talk with the public health officer there, and according to him, the top three common diseases in the village are malaria, diarrhea, and flu, though hypertension (high blood pressure) and diabetes are becoming a problem especially among the elderly.

At the end, we had an opportunity to drive around the village to see some homes of the Thai-Karen, which look different from the traditional Thai examples. It was not long before the sun was starting to set and so we had to leave the area (local roads are without pavement and lights), but the staff at RTIC were kind enough to offer me to visit again, next time staying for a few days. And there is also Tak province, sometimes called the "humanitarian aid mecca of Thailand", and the Thai-Burma border area there, about an eight-hour drive from Bangkok. I definitely have to and sure will come back again.

Many thanks to my friend. :-)

JAIH-S International Health Training Camp 2008.

I was given an opportunity to participate in a four-day global health training program that was carried out by the Students' Division of the Japan Association for International Health (JAIH-S) from March 13th to the 16th. The main aim of this annual program is for the participants to be able to (1) create an image of what working in the global health field is like, and (2) know what you can do and how to start it.

We had lectures done by people currently working at the front lines in this field, including staff from the International Health Center Japan, a tropical medicine researcher, an epidemiologist, officers from the Ministry of Health, Labor, and Welfare (MHLW), and health specialists from NGOs, JICA (Japan International Cooperation Agency), and UNICEF. The lectures were followed by many group activities including discussions, debates, and a PCM (project cycle management) workshop which we had to work on through a night to complete.

My impression? Well... frankly speaking, I felt a little weird throughout the program. Of course, all the participants were highly-motivated, deep-thinking, yet thoughtful people who had gathered from around the country, and without question, the chats with them were really stimulating and one of those memorable times. However, most, if not all of them, were drawn by the terms 'global health' or 'international health', while on the other hand, my interest doesn't necessarily have to go beyond the border, as my 'theme' is community-based health care or primary health care (PHC). Yes, often times, these words have been talked about more in the developing communities rather than the industrialized ones so no doubt it does have a 'global health' taste to it, however, when you take a close look at the developed communities, you actually do see many forms of community health, and plus, there are many things these communities around the globe can learn from each other.

And, another reason for my feeling not right is probably due to the fact that many of the speakers have already literally abandoned the clinical part of being a physician. In other words, many of the doctors in this field do not see patients anymore at a hospital or clinic. Yes, it is true that so-called logistic-type jobs are more needed than specialized people like doctors or nurses. For example, when you take infectious diseases, the main underlying issues in the developing communities are more basic, such as sanitation or health education, and tackling these issues is the most radical solution. Treating patients and prescribing drugs is also a job that can not be cut, but it does little in terms of remedying the bigger picture. So what's needed in the field of international cooperation? Leadership, management, communication skills, and creative thinking. It's what one of the lecturers said, and I agree.

However, at this point, I have no thought of abandoning the clinician's work. Well, that's what I am studying medicine for right now! To obtain specialized skills. Yes, I am interested in public health, community health, and doing positive things for the bigger public, but I want to do that through interacting with the patients. So the image of my future I have right now could be called 'clinical epidemiology-based community health'. In other words, through interacting with the people, know the community, know its strengths, weaknesses, and hidden potentials, and do something creative to bring out their strengths to make the community happier as a whole, with the people in the community. This training program helped me reaffirm my interest.

By the way, I had a chance to talk with Dr. Honda, the founder and current chair of SHARE, the biggest non-profit organization in Japan specializing in international health cooperation, and I was deeply moved by his talks, as he and I had so many common interests... his 'theme' also sounded like community-based health care and primary health care (PHC). :-)

Goodbye to a flying sports car.

Fleet rationalization is happening everywhere in the commercial aviation industry. With fuel prices sky-rocketing, airlines are doing whatever they can to cut costs, and fleet simplification is one of them.

That is no exception with the airlines of Japan too. When Japan Airlines (more commonly referred to by its ICAO three-letter code JAL) and Japan Air System (JAS) merged in 2002 to take on All Nippon Airways (ANA), which had and still has the biggest share of the domestic market in terms of passenger numbers, it not only created an initial series of coordination problems but also a diverse fleet as well, as the two only had one aircraft type in common. Operating more aircraft means more maintenance work, a larger spare parts inventory, more training of its employees, etc, which adds to costs.

For example, the competitors in the short-haul market are the Airbus A320 family, Boeing's 737 family, and the McDonnell Douglas (merged into Boeing in 1997) MD-80/90 series. Production of the latter was terminated not long after its takeover by its former arch-rival, so essentially the A320 and 737 have the market all to themselves now.

JAL had been operating a substantial fleet of 737s, while JAS had been loyal to the Long Beach-based manufacturer, operating the MD-80 and also acquiring the advanced MD-90s in the mid-1990s. So the merged airline operating two (or three) major types for the short-haul sector was naturally deemed uneconomical, and the decision was made to acquire newer 737s to eventually replace the Douglas twin-jets. JAS operated the MD-81, MD-87, and MD-90, and the first to say farewell became the MD-87.

First delivered to JAS on June 3, 1988, the fleet eventually built up to eight aircraft. The MD-87 is basically a MD-82 (a MD-81 with more powerful engines) with a shortened fuselage, compromising capacity for longer range and better take-off and landing performance. JAS acquired these 117-seat jets, sometimes nicknamed the "flying sports car" for its superior climbing performance, to bring jet age to the local regional airports in Japan with limited runway length. These markets had long been served by the Japanese-built NAMC YS-11 turboprop airliner.

After the merger, all eight were repainted in JAL's new "Arc of the Sun" corporate livery which was developed by Landor Associates, however, as the merged airline took delivery of more newer 737s, it was only a matter of time before retirement. So the first of eight was withdrawn from service in October 2007, and the ultimate aircraft is now planned to operate its last revenue flight on March 31, 2008, flight JL1386 from Nanki-Shirahama to Tokyo's Haneda airport. All were already withdrawn from scheduled service by the end of February, and have since been operating mainly as back-up equipment.

The MD-87 was never the most popular jetliner like Boeing's venerable 747, but it did have its own niche, and brought jet age to the regional airports in Japan, boosting tourism. It surely will be missed by its crews, employees, and those local airplane spotters. Fortunately, many are now finding a new lease of life in Thailand with low-fare airline One-Two-Go (a subsidiary of Orient Thai Airlines), instead of being reduced to piles of metal somewhere in the southwestern USA where many older jetliners end their life.

Farewell, sports car in the sky. :-)

A visit to Hinohara Village Clinic.

Hinohara Village is part of Tokyo, located in the northwestern corner of the huge city. The place neither looks like Shinjuku with the jungle of 50-story buildings nor Azabu with all the four-star restaurants and residences of the affluent, but more like a gathering of homes in a mountainous countryside. From central Tokyo, it takes two and a half hours by train to reach the nearest station and a bus ride from there that takes a further 40 minutes.

I had an opportunity to visit the village clinic here on the 25th of February. Two doctors work here, one of whom I know from a primary medical care seminar that took place last September, Dr. Aizawa, and when I asked him whether I could visit to see what health care in a remote area is like, he kindly gave me a nod. So on this morning I got up at 5:00am (still a bit dark around this time of the year), hopped on the train, and headed for Musashi-Itsukashi, the station nearest to the village. And since there are only six bus round-trips between the station and the village, Dr. Aizawa was kind enough to pick me up on the way from his home to the clinic.

The road winds between the mountains along a river, and I realized a lot of snow still remains. There are so many cedar trees on these mountains, many so close to each other, and Dr. Aizawa tells that these were planted in the 1940s for war, but have been left as they are ever since they became unnecessary soon after. The population of the village is now around a little over 2,850 people, with an amazing decreasing rate of 4-5% per year in recent years, with last year's number being 3,000, and the year before a little under 3,200. People over 65 account for 41% and families of the young generation continue to move to urban areas, no wonder there's no high school and the number of students in the village's sole middle and elementary school stand at 30 and 90, respectively.

This day was a relatively easy day for the clinic staff, which is comprised of one office personnel, one medical technologist, three nurses, and two doctors, as they only had about 30 outpatients. The clinic has a small inpatient ward that can accommodate two, but is usually only used in emergencies since a general hospital is about a 40-minute drive from here. Unlike the big hospitals in the urban areas, patients who come here complain of a variety of disorders, from common problems such as simple chest pain caused by falling down, or common colds, to major diseases such as diabetes and other lifestyle-related disorders or pneumonia.

In the afternoon, I had an opportunity to see what is called an "Oushin", which is a house call where a doctor goes and sees the patient at his or her home. I saw a similar activity at Ukima Clinic. (See post 2007/11/20) But unlike in the urban areas of Tokyo, the houses are so far apart, Dr. Aizawa says it could take well over 30 minutes to reach the home. Fortunately today, the house that gave us the call was close enough. It was a big 2-story house with an old couple living together, their children having already moved out to the urban areas with their families, leaving many rooms unused. The husband could not walk anymore, so his wife was taking care of him. Dr. Aizawa adds that many homes are too large, and since only a few live in them, many are cold even inside the house. There are sometimes severe cases, such as when they found a handicapped elderly living alone in a large house on top of the mountains with malnutrition.

Although the current state of health care here could not be said convenient, Dr. Aizawa says that it's much better than that of villages in other prefectures. Local governments in Tokyo are eligible to receive a considerable amount of financial assistance from the metropolitan government, partly due to the fact that they have made it a rule to place at least one doctor for each and every single local government, including small villages with a few hundred people. Meanwhile, not far from Hinohara Village is the countryside of Yamanashi Prefecture, where he says health care is in a "much worse condition". He added that you can even notice the difference in the quality of the road pavement when crossing the border.

There's much more he talked about this day, especially about his early years as a doctor in the remote islands of Tokyo floating in the Pacific. But for now, I'll stop here. Through this visit, I was able to get a general idea of what health care in a remote area is like, at least in Tokyo. I should visit other prefectures too. I would like to thank the kind staff at the clinic for making this visit possible. :-)

Farewell to an old local friend.

January 22nd marked the last day of regular revenue operations by Tokyu's 8000 series train.

I've lived most of my life in Japan near the Toyoko, Denentoshi, Oimachi Lines, and grew up watching the train's stainless side look and hearing the unique thundering sounds. Whether it's a train you use every day or a local shop or restaurant you visit regularly, these are things that are usually taken for granted, things that you don't really stop to think about. But once you know they're going to be gone soon, you suddenly realize that times are changing. You miss these things you've never missed or even cared to think much about before.

The 8000 series started service in 1969 and for almost four decades served the people of Tokyo and Yokohama on the Toyoko Line, which connects the two big cities, hence its name. These series of trains were the most technologically-advanced of its time, being the first to be controlled digitally, enabling trains to run on tighter schedules, and has claims to being the first in the world to incorporate a field system chopper circuit which made regenerative brakes possible. With its length being 20 meters, it was also much longer than the commuter trains of its time, helping to make way for Japan's economic growth of the 1970s.

On January 13th, the gradual replacement of the series by newer, more advanced types was completed for the Toyoko Line with much fanfare, where amazingly over a thousand people from local residents of all ages to train afficionados gathered to bid farewell to the grand old workhorse. Truly a sign that it was loved by everyone. The last remaining example (ironically the first to roll off the production line), which served the Oimachi Line, a 10.4-km local route in southwestern Tokyo, was retired on February 22nd.

Tokyu Corporation has transferred many of these trains to Izukyu, a wholly-owned (but financially-troubled) subsidiary in Shizuoka Prefecture carrying holiday-makers to resorts on the Izu Peninsula. A handful have also been donated to Indonesia as part of Japan's official development assistance (ODA) to help set up Jakarta's railway infrastructure.

Adios. :-)

Studying for the CBT.

January was a busy month, well sort of.

4th-year medical students in Japan now have to go through a set of exams called the Common Achievement Tests (CAT), which comprises an objective-structured clinical examination (OSCE) and a computer-based test (CBT). The former tests basic clinical skills while the latter checks to see if you have the essential knowledge that is deemed necessary to begin clinical rotations. So basically, the CBT part is a complete review of the 4 years.

However, like most other tests, studying for the CBT is test-focused and test-oriented. It's not something you should start off by opening your textbook from two years ago, but more like get the unofficial guide and workbook (like the First Aid for the USMLE) and study based on that. Why unofficial? Because there's no such thing as an official guide nor workbook. All they give us is a handout with a brief explanation of the exam, and the exam itself is not made public. So what this means is the quality of the exam does not improve. The unofficial workbook is made up of questions that have been remembered by past examinees, and so though it is not the actual past exam, it is the closest one available, and at a glance, there are tons of questions that are not clear and some just lack explanation to the extent that we can come up with more than one answer.

Finished the OSCE two days before Christmas, and now the CBT. One of my biggest concerns is whether I would be able to keep my concentration through the exam, most notorious for its length of seven hours. The unofficial workbook is what I along with everyone else is doing, but there are six volumes to the series totalling over 3,000 questions. Since I'm the kind of person who can't concentrate for long in his own room, people would find me studying in a Starbucks or a McDonald's for hours.

By the way, it's been a pretty cold winter, and Tokyo, which seldom gets snow much less any accumulation of it, has so far had 5 centimeters of snow twice this year.

Looking back at 2007.

Time flies.

Oh boy, I wonder how many times I've said this phrase on this blog. But well, it's true. But it's also true that this year was full of meeting new friends and discovering my interests... and myself.

In spring, I participated in VIA's (a non-profit based in San Francisco and on the Stanford University campus) Exploring Health Care program to learn about health care in the USA and in the Bay Area in general. Along with medical students and undergraduates thinking of going that way, we hopped around the area to see hospitals, clinics (both private and free), homeless shelters, shadow doctors' rounds, participate in class to get a taste of what medical education is like there, and much much more over a period of 2 weeks.

The gay clinic called the Magnet, located in the heart of Castro, the gay mecca of the country, is what sparked me into community-based health care, or in other words health care that involves the entire community. What's amazing is that it's not merely a clinic but has the potential to act as a catalyst to bring a people together and empower them as a whole. I'll talk about this much more in detail another time...

And this summer, I found myself in a 11-day primary health care (PHC) training program at Mahidol University's ASEAN Institute for Health Development (AIHD) in Thailand. Along with nursing school students from that country, we followed a highly-concentrated course to see health care in the urban areas of Bangkok (including the slums), go up 4 hours by bus to the rural areas in Uthai Thani Province and stay in a village to do some epidemiology field work 'for beginners', and do a presentation at the end with our groups.

The rural area home-stay and the interviews and other interactions with the villagers totally changed how I think, and this is where PHC and community-based health care got on me. Again, I have to save another time to tell this in detail...

And last but not least, DOCS (acronym for Development of Clinical Skills), which we formed with the former participants of the Exploring Health Care program in our university to get a head start and practice clinical skills, played an important role in my life this year. We found energetic, passionate, student-caring doctors who were willing to teach us, in a university where we once felt finding those kind of mentors was devastating. Moreover, the activities led me to knowing general medicine, family medicine, and primary medical care, which then led me to Ukima Clinic, a community-based clinic up in northern Tokyo. (See post 2007/11/20.)

The more I look back at this year, the more the activities I was involved in get connected in one straight line. Compared to a year ago, I couldn't have imagined myself where I am now. This year helped me discover what my true interests are in (at least for now), and now I can much better describe the bigger picture of the doctor I have in mind for my future.

Wishing everyone a happy holiday season and another great year! :-)

Autumn leaves and climate change.

Autumn... trees are starting to change color, like a rendering of warm colors on a canvas. Temperatures have gone down, and I notice it's almost the end of November. Time flies.

Last Monday, I paid a visit to Kita-no-maru Park near the Imperial Palace in Tokyo. Spent maybe about an hour or two sitting on the bench, gazing at the picturesque scenery adorned with beautifully colored trees, while some little nursery children played with parents and other people sat on the lawn reading books or just taking a nap. Calm, quiet, and peaceful. Birds flew from a tree to another from time to time.

An oasis in bustling central Tokyo.

When you talk of autumn leaves in Japan, Kyoto is the first place that comes to mind. The former capital of Japan is just purely beautiful during this season. The scenery of numerous history-rich artistic temples with a balanced mix of red, orange, yellow, green, and sometimes pink and purple leaves is just simply magnificent.

However, peculiar things are starting to happen in Kyoto. The autumn period is becoming shorter and shorter year after year. Compared to half a century ago, leaves now start to change color two weeks late, and leaves fall off the trees a week late, shortening the "autumn leaves season". Why? It doesn't take a rocket scientist to guess... the temperatures at Kyoto have risen, widely thought to be the result of global warming. According to records, the average temperature of Kyoto is three to four degrees (Celsius) higher today than in the Meiji period, about a century ago.

Kyoto is where the international community agreed on a protocol to reduce greenhouse gases, and the host country promised to cut 6% by 2012 from the 1990 level. However, the reality is emission has increased by more than 8%. Experts note that the Japanese industries had already gone through a series of rigorous cost cutting measures in the 1980s through developing new technologies, thus cutting carbon emissions, so much of the current plans focus on taking advantage of the Kyoto Mechanism, such as emissions trading (ET) and joint implementation (JI), and also promoting and persuading offices and homes to save more energy.

We, as individuals, need to act now. For our future, not only to help our environment but also in order not to lose trust from the rest of the world. There are lots we can get done if we all do it. :-)
