Purpose: With the aim of improving the efficiency of smoking cessation treatment, we analyzed and classified various factors to identify the relationships between the background of patients and effects of treatment, and examine their characteristics.
Methods: We conducted a questionnaire survey to collect information on the situation of patients, and obtained their treatment data from medical records.  Decision tree analysis, a data mining method, was employed to examine these data.
Results: According to the results of the survey, the smoking cessation rate was 80.4%.  The rate was associated with CO concentrations in the breath at the initial examination, nicotine content in cigarettes smoked by patients, and the daily and total number of cigarettes smoked.  The smoking cessation rate among patients under emotional stress was 76.2%; the rate was higher when patients were able to reduce their mental stress levels.
Conclusion: We identified characteristic relationships between the background of patients and the effects of treatment, and they proved to be useful for the improvement of the smoking cessation rate.

It has been experienced that Kampo, with its philosophy that every disease is psychosomatic in origin and that herbs affect both the psyche and the soma, sometimes has a dramatic effect on somatoform disorders, though there has been no study examining the effects of Kampo on somatoform disorders. In this preliminary study, the morbidity of somatoform disorders among patients who visited the Keio Kampo Clinic and the patients' psychological well-being were examined.
One hundred patients (17 males and 83 females; mean age [±SD], 39±16) who sought Kampo treatment for the first time at Keio University Hospital participated in this study. A Japanese checklist derived from the somatoform disorders schedule (version 1.1) was used to check the somatoform symptoms. To assess psychological well-being, the subjective well-being inventory (SUBI) was performed. The subjects' clinical records were examined afterwards to rule out symptoms which could be medically explained.
Somatoform patients and medically ill (non-somatoform) patients were 65% and 26% of the total respectively. The somatoform patients showed significantly lower SUBI positive scores than the non-somatoform patients (p=0.042), while SUBI negative scores were significantly higher (p=0.001). Among the somatoform patients, there was a negative correlation between numbers of somatoform symptoms and SUBI positive scores (r=0.267; p=0.032), and a positive correlation between numbers of somatoform symptoms and SUBI negative scores (r=0.337; p=0.006).
Following the SUBI scores through treatment courses may lead to a better understanding of the pathology of somatoform disorders and to more effective use of Kampo.

To help medical doctors practicing Kampo medicine suggest appropriate acupuncture treatments for individ­ual patients, a study group made up of 7 acupuncturists and 5 medical doctors developed an acupuncture cur­riculum. The group provided a learning program based on the curriculum for 16 medical doctors in charge of outpatient Kampo services in a research institute. The learning program consisted of a lecture and practical training, and a total of 4 sessions were held. At the end of each session, a test was conducted to examine the participants' level of understanding. After the completion of the learning program, a questionnaire survey was conducted to confirm the usefulness of the acupuncture curriculum for the practice of Kampo medicine. The mean number of participants per session was 10.8 ± 1.3. The mean test score was 9.3 ± 0.5 (full score : 10). In the questionnaire, 14 out of the 16 (88%) answered that the acupuncture curriculum was useful or relatively useful for the practice of Kampo medicine. On comparing the numbers of new acupuncture patients with a his­tory of outpatient Kampo service use before and after the acupuncture curriculum, there was a 1.8-fold increase after it. The results support the usefulness of the acupuncture curriculum to understand acupuncture and practice Kampo medicine. Further evaluation is necessary.
