International Collaboration Beyond the Culture Gap

Pages 1 2 3 4 5 6

Based on my experience of international collaboration, I decided to begin an opportunity for international exchange for Japanese young doctors and created "The Study Group for Nerve and Spine" with Japanese friends in 1996. Prof. Rydevik and Prof. Olmarker helped us. Eisai, which sponsors the International Fellowship of ISSLS, gave us financial support.
We have a meeting once a year and we choose a different theme every year. Based on that theme we hold a symposium, where Japanese top class young researchers present papers. We present papers and discuss all in English. We invite foreign guest speakers distinguished in that field. For ten years up to now, foreign guest speakers have consisted of 22 researchers from 10 countries, the most from the United States, 9.
International collaboration can be made unexpectedly beyond time and national border. I published a report of "Metaphysial Dysostosis (Jansen type)" on JBJS in 1976. It was a very rare congenital systemic skeletal disease. In 1996, twenty years after that, I got mail from the United States, asking to send a sample of the patient's blood for a gene analysis of metaphysial dysostosis. This is my precious experience to know that an early study can be reexamined by a new technology many years later in a different country.
I think it is important that we, as doctors, be concerned about our patients' pain. This is a topic that occupies me now. Descartes' theory of pain was the origin of the organic model. Descartes thought the impulse traveling from the site of injury to the brain produced pain. The great development in anatomy and physiology in the nineteenth century created the scientific basis for believing that pain was just an electrical impulse traveling along the nerves. But there had been a different concept before Descartes. In the right figure, "The Flagellation" by Francesca, pain was presented "within a complexly layered historical world of religious meaning, social values, and personal loss." Pain had been considered emotional, cognitive and social, not simply physiological, before modern science developed.
There have been some studies suggesting that low back pain is not caused by mere organic damage. The typical one is shown in this slide. This study examined records of compensable injuries in 1977 in Washington State. Patients with low back pain received more than one-third of all compensation payments. Astonishingly, 75% of these patients showed no finding of organic disease. This means pain should be considered not in a one-dimensional organic model but in a multidimentional model which encompasses physiological, emotional, cognitive and social aspects of pain.
There is a saying in Japan that blind people touch the elephant. Someone touches the ear and says the elephant is like a big fan. Another says it is like a big pot, touching only the belly. Another says, like a big hose, with the nose and another says, like a big pillar, with a leg. This saying can be applied to a study of low back pain. We cannot understand low back pain completely, if we study only in our own limited field.
This is a slide in Prof. Nachemson's lecture. Now we should study brain, because low back pain is perceived in the brain. It is important to clarify the mechanism of perception of low back pain in the brain, in order to improve the treatment of our patients. This means that a multidisciplinary approach is essential for new knowledge in low back pain.
The pain we see clinically is not the pain examined in the laboratory. The pain experienced by a patient is "living pain," according to Dr. Leriche. "Living pain" cannot be divided into physical pain and mental pain. It can be considered two hands with fingers interlaced. Pain, especially chronic pain, is interlacing of body and mind.
We, all the members of ISSLS are working for the same purpose. We should study in collaboration, crossing interdisciplinary borders. I think it is the best way of improving diagnosis and treatment of low back pain.
International collaboration beyond national and cultural borders is also very important. The members discussing at the meeting are good rivals and good colleagues, who can understand one another's work best of all. Competition is important, but collaboration is more important. The history of ISSLS demonstrates it, and I believe it, based on my experience. I am sure it will lead to further development in the study of low back pain in the 21st century.
