Report of the 71st Annual Meeting of the Japan Society for Oriental Medicine Special Program1 — “Pre-and Post-Graduation Education of Kampo Medicine for the Next Generation”: Clinical Practice on Kampo Medicine / 日本東洋医学雑誌

At the 71st Annual Meeting of the Japan Society for Oriental Medicine held in August 2021, we conducted a special program focusing on Kampo medicine education, “Pre-graduation post-graduation Kampo medicine education for the next generation.” The following is a summary report on the practical training in Kampo medicine at each educational facility where the project was conducted. We recorded videos with explanations of topics in advance : “Four examinations,” “Decoction and crude drugs,” and “Acupuncture and moxibustion.” The report on the hands-on training in Kampo medicine was viewed 501 times by medical students, educators, and the society members across the country. This initiative was the first nationwide educational activity of the society.

Kampo Medicine Treatment for Coronavirus Disease 2019 (COVID-19) / 日本東洋医学雑誌

The Japan Society for Oriental Medicine (JSOM) has made various efforts against coronavirus disease (COVID-19) to build evidence. JSOM has launched an academic society-led clinical research project on COVID-19 based on the concept and characteristics of Kampo medicine, including (1) prevention of disease by activating the immune system to regulate body conditions (pre-symptomatic stage of illness), (2) symptom alleviation in the mild and moderate stage and prevention of aggravation (acute to subacute stage of illness), and (3) early recovery and improvement of prolonged symptoms (late stage of illness). Since the declaration of the pandemic, the special working group has conducted the following activities : enlightening academic members, lobbying other academic societies, preparing research protocols, establishing research groups, conducting ethical reviews, responding to the research disclosure system, preparing protocol papers and review articles as the basis for the research, reporting research progress, soliciting case reports, warning against Chinese medicine use, requesting for research support funding, and revising the JSOM website. We also discuss the interpretation of COVID-19 from the perspective of Kampo medicine and the direction of the selection of Kampo formulas in this report.

A Case of Sweating Disorder Successfully Treated by Keishikaogito Based Prescription / 日本東洋医学雑誌

There are multiple options for treating hyperhidrosis, including Kampo medicine. However, as for acquired idiopathic generalized anhidrosis, steroid therapy is the only way to treat the patients. There are few clinical reports including Kampo treatment for anhidrosis. We report a case in which keishikaogito based prescriptions were effective in treating symptoms caused by decreased sweating. A 69-­year-­old woman visited our institute in June 201X, complaining of reduced sweating and abnormal feelings about body temperature. Her physician prescribed various sorts of Kampo medicines, but no improvement had been shown. We considered that she was not able to sweat and had water accumulation under her skin. She was given Keishikaogito based prescrip­tions, and she came to sweat spontaneously and abnormal feeling about body temperature improved. Honzo-biyo says “Astragalus promotes sweating if there is no sweating, stops it if there is sweating.” Keisetsu Otsuka said in Kinki-yoryaku-kowa that Astragalus works in both cases with too much and too little water. Kampo treatment especially containing Astragalus can be effective for sweating disorders.

A Case-series Study of 10 Patients Successfully Treated for Chi-no-michi Syndrome with Nyoshinsan / 日本東洋医学雑誌

Nyoshinsan is one of the Kampo formulations for the treatment of hot flash or dizziness, which are typically seen in chi-no-michi syndrome (characterized by physical and/or mental symptoms related to female hormone variation). But nyoshinsan is less frequently prescribed than three major formulas in gynecological field including tokisyakuyakusan, kamishoyosan and keisibukuryogan. Furthermore, few case series study of nyoshinsan has been reported so far. To elucidate clinically useful indication sho of nyoshinsan, we retrospectively analyzed medical records of the patients prescribed nyoshinsan for past 5 years in our institute. In consequence, majority of patients prescribed nyoshinsan had both blood stasis and qi-abnormality including qi-deficiency, qi-stagnation and qi-counterflow due to physical or mental stresses. On the other hand, they rarely had signs of fluid retention. These findings may be useful for more effective clinical application of nyoshinsan.

Diseases and Findings of the Shigyakusan Effective Cases in Our Institution / 日本東洋医学雑誌

We retrospectively surveyed and analyzed medical records of 41 effective cases with shigyakusan including shigyakusan decoction and shigyakusan extract. In classics, fullness in chest and hypochondrium and rectus abdominis muscle stiffness along with coldness of the extremities is regarded as important clinical indication of shigyakusan. In this analysis, patients who present fullness in chest and hypochondrium are more than 90%, and patients presenting rectus abdominis muscle stiffness are more than 60%, confirming that these findings are important. On the other hand, although more than half of the patients feel excessive sensitivity to cold, only about 20% of the patients had coldness of the extremities as objective Kampo findings in their medical records. Until now, coldness of the extremities has been considered to be important because shigyaku means Japanese expression of it. But our obtained results show that shigyakusan is used for the patients who do not have cold extremities.

Solution Proposal for 5 Challenges to be Resolved in Formalizing the Logical Format of Kampo-Based Diagnosis by Building Consensus Among 6 Medical Institutions Specialized in Kampo Herbal Medicine / 日本東洋医学雑誌

We are planning a study focused on the gathering of clinical data for the purpose of formalizing diagnostic logic at 6 institutions specialized in Kampo-based medical examinations. However, during the planning stage, it has been recognized that there are a large number of Kampo formulas to be studied, and differences among faculties and individuals exist regarding how to identify each Kampo formula, methods of gathering findings, and the evaluation of efficacy. Here we report the solution proposal reached after building consensus among all participating faculties on these issues. After raising the issues, conferences were held for each of them, until a unanimous consensus was obtained. As a result, the following conclusions were reached. Thirty-three Kampo formulas were selected as targets for the formalization of diagnostic logic. In addition, the range of dosage forms, crude drug ingredients, and permissible dosages for each Kampo formula were determined. Regarding clinical findings for these Kampo medicines, the items to be collected and evaluation criteria were also established. The criteria for evaluating the validity and safety of each Kampo medicine were decided, together with the grading and timing of evaluation. We hope that our solution proposal reached after building consensus becomes the basis for Kampo research in the future.

Four Cases of Upper Gastrointestinal Symptoms Successfully Treated with Ryokeijutsukanto / 日本東洋医学雑誌

Case 1 was a 28-year-old female who had epigastric discomfort and epigastralgia for three months. These symptoms were accompanied with dizziness, faintness and hot flush. Right after taking ryokeijutsukanto, her dizziness, faintness and chillness of foot disappeared with improvement of gastrointestinal symptoms after two weeks. Case 2 was a 40-year-old female who presented prolonged nausea and epigastralgia for eight months. She also complained of dizziness and strong globus sensation when taking meals. After taking ryokeijutsukanto, her appetite improved in a week and gastrointestinal symptoms improved in 3 weeks. Case 3 was a 15-year-old female whose complaints were nausea, epigastric discomfort, palpitation, dizziness and globus sensation consequent to swaying feeling after riding a roller coaster. These symptoms including nausea improved after taking ryokeijutsukanto with 3g of magnolia bark for a week. Case 4 was a 28-year-old male who presented severe appetite loss and epigastric discomfort when he got tired. He also complained of faintness. His faintness disappeared after taking ryokeijutsukanto for 2 weeks. His appetite also improved after four weeks. Clinical courses of these cases suggest that ryokeijutsukanto may be useful for the treatment of upper gastrointestinal symptoms including functional dyspepsia, i.e. fluid retention with qi-counterflow.

A Case of Anal Prolapse of Internal Hemorrhoids with Anal Pain Successfully Treated with Teikosan / 日本東洋医学雑誌

Teikosan is an herbal medicine that was developed from the Japanese herbal (Kampo) medicine hochuekkito. Unlike hochuekkito, teikosan does not include Zizyphi fructus and Zingiberis rhizoma. Instead, Cnidii rhizoma, Scutellariae radix, Coptidis rhizoma, Angelicae dahuricae radix, and shakusekishi are included as constituents of teikosan. The clinical indication of teikosan is anal prolapse with pain that is more severe than that considered appropriate for hochuekkito treatment, but there have been few clinical reports before. Here, we describe a case of anal prolapse with anal pain, which was successfully treated with teikosan. A case was a 47-year-old woman whose chief complaint was anal prolapse of internal hemorrhoids with pain. She was considered as indication for hochuekkito, but her symptoms including anal pain were so severe that we prescribed teikosan, especially because Angelicae dahuricae radix, Scutellariae radix, Coptidis rhizome in teikosan were expected to improve her anal pain. After the administration of teikosan, her symptoms including anal pain have much improved. Teikosan should be considered as a therapeutic option for anal prolapse with severe anal pain or inflammation.

Three Cases of Meniereʼs Disease in the Elderly SuccessfullyTreated with Kampo Medicine / 日本東洋医学雑誌

We report three closely watched cases of intractable Meniere's disease in the elderly that were successfully treated with Kampo medicine. Case 1 is a 75-year-old female. At the time of the 4th Meniere's attack, we gave her western medicines such as isosorbide, but she had a significant hearing loss. Then, we administered hachimijiogan extract granules, and her hearing level improved and she had been free of Meniere's attack for 23 months. Case 2 is a 78-year-old male. We diagnosed as bilateral Meniere's disease and treated him with western medicines such as isosorbide. In September of year X, his hearing level in the left ear worsened despite the treatment, so we prescribed hachimijiogan extract granules. After the treatment, we found the patient's hearing improved and nystagmus decreased gradually. He has also been free of Meniere's attack for 9 months. Case 3 is a 70-year-old male. He had repeated episodes of vertigo in spite of the administration of western medicines. After we prescribed shimbuto extract granules, vertigo attack and nystagmus disappeared. He has been relieved from Meniere's attack for 8 months. These cases indicate that Kampo therapy is one of the useful therapeutic options for intractable Meniere's disease in the elderly.

<b>Usefulness of Senkito when Taken only During Pain in Cluster Headaches</b> / 日本東洋医学雑誌

<p>This report describes a case of cluster headaches that was successfully treated with Senkito. The patient was a 46-year-old female. She had been having attacks of cluster headaches that had continued for 3 days at the change of seasons since she was 30 years old. During an attack, she took a triptan preparation and non-steroid anti-inflammatory drug (NSAID), but they were not effective. Recently, the attacks had been increasing in frequency and continued for 1-2 weeks. She visited our hospital for Kampo treatment. We diagnosed her as having <i>oketsu </i>and <i>kiutsu </i>; therefore, we prescribed tsudosan, and the frequency and strength of the attacks decreased. Even if NSAIDs were effective for headaches, they were not consistently effective. We re-examined her and found she had inside biryokotsu, which is tenderness in the orbital part of the frontal bone. We diagnosed her headache as including biryokotsu pain. We prescribed Senkito as required for her biryokotsu pain. It was very effective and the headache vanished after only 30 min. Generally, the potency of Kampo medicines with few structural components is higher than that of those with many structural components. Senkito has only five structural components ; therefore, we concluded that Senkito is effective not only for everyday use but also for use when required. Senkito is one of the most effective formulations for treatment of biryokotsu pain,especially the patient with inside of biryokotsu tenderness.</p>

<b>Three Asymptomatic Cases of Suspected Drug-Induced Liver Injury Possibly Caused by Scutellariae </b><b>Radix</b> / 日本東洋医学雑誌

Case reports of drug-induced liver injury caused by Kampo medicines are on the rise, but most of them are noted for related symptoms such as jaundice. Usually, severe liver injury is detected by chance upon routine medical checkup. Recently, we noted 3 cases of suspected drug-induced liver injury caused by orengedokuto, saikokeishikankyoto and bofutsushosan. In these 3 cases, maximum ALT was under 100 IU/l and no symptoms related to liver injury were observed. Early detection by blood test was useful, and appropriate treatment quickly improved and normalized the abnormal values associated with liver injury. We should always be alert for drug-induced liver injury caused by Kampo medicines, especially when prescribing formulations that include <i>Scutellariae Radix</i>. We also emphasize the importance of scheduling blood tests when prescribing these formulations.

<b>Clinical Characteristics of Cases Treated with </b><i><b>Kinkiyoryaku</b></i><b>-Described Hontonto, Including Two Case R</b><b>eports </b> / 日本東洋医学雑誌

Case 1 was a 24-year-old female suffered from the feeling that her throat was obstructed ; this occurred after she had to talk loudly in front of many people. Case 2 was a 51-year-old female who complained of a palpitation attack ; this occurred after she underwent a hysterectomy. We diagnosed these symptoms as “<i>hontonki</i>.” <i>Hontonki </i>is a case of symptoms rising from the lower abdomen into the chest and throat with feelings of anxiety. When these symptoms appeared, the patients felt as if death were upon them, but when they disappeared, the patients soon felt healthy. There are certain medicines that can be used to treat <i>hontonki</i>. We administered <i>Kinkiyoryaku </i>hontonto (i.e. hontonto as described in <i>Kinkiyoryaku</i>) to them, and it was very effective.<br>We undertook a retrospective analysis of these two cases, along with 8 other cases successfully treated with <i>Kinkiyoryaku </i>hontonto at our hospital over the last 11 years. We found the common clinical characteristics of <i>hontonki </i>events were paroxysmal symptoms with feelings of anxiety. There are some differences between the clinical characteristics of <i>Kinkiyoryaku </i>hontonto from those of <i>Chugobikyuho </i>hontonto (hontonto as described in <i>Chugobikyuho</i>). The cases of <i>Kinkiyoryaku </i>hontonto are not <i>kyosho </i>(hypofunction) as those of <i>Chugobikyuho </i>hontonto are. Either they have heat symptoms or they do not have coldness, and they have shoulder stiffness or headache as some of the other <i>oketsu </i>symptoms.

<b>Japanese Literature Survey of Tongue Findings for the Purpose of Creating a Unified Multicenter Description of Clinical Tongue Diagnoses</b> / 日本東洋医学雑誌

In Kampo medicine, a tongue examination, whereby the shape and color of the tongue is observed, is thought to reveal the constitution and condition of the patient. In Japan, numerous books on this tongue examination have been published. However, tongue findings are expressed differently in these books, and a standard description for such findings has yet to be established. A standard description would be useful when examining the tongue, and when educating students of Kampo medicine. We therefore compared how tongue colors and shapes were expressed in the Japanese literature on tongue examinations (12 publications).<br>Using these results, we have arrived at a standardized description for tongue findings in accordance with Kampo specialists of tongue diagnoses at many facilities. In the process, we focused on easily recognizable findings that can be noted with short clinical examination times, and that can also be understood by beginners.

<b>Standardization of Kampo Medical Findings in a Specialized Kampo Medical Service Facility </b> / 日本東洋医学雑誌

Standardizing Kampo medical findings is a significant challenge in Kampo medical circles. These findings are fundamental to Kampo diagnosis. This paper introduces our attempt to standardize these findings in a specialized Kampo medical service facility.<br>We started our project with verbal standardization. Nine medical doctors, all of whom were Kampo advisors or Kampo specialists, discussed issues such as subjective and objective findings, including those of the tongue, pulse, and abdomen, as well as the selection of target items, criteria for judgments on each item, and associated issues. When discussing the above issues, descriptions in prominent traditional Kampo texts were given most importance, and the wisdom of famous Kampo doctors since the Showa period was also given weight. In addition, we focused attention on clarifying the criteria for making judgments.<br>One hundred and twenty items were selected as subjective Kampo findings. We selected 12, 6 and 10 items as objective Kampo findings in the tongue, pulse, and abdomen, respectively, and provided criteria for judgments with each.<br>Our next challenge is to spread these standardizations in Kampo medical circles.

<b>Efficacy of Kampo Therapy in Chronic Tinnitus Patients </b> / 日本東洋医学雑誌

Treating tinnitus with modern Western medicines is difficult. Several studies have reported that Kampo medicines are efficacious for treating tinnitus, and therefore, it is expected that these medicines will gain widespread use in the future for tinnitus treatment. We retrospectively examined the efficacy of Kampo medicines prescribed on the basis of Kampo diagnoses for chronic tinnitus patients. The study population included 331 patients (114 men, 217 women) and average age was 57.8 years. The overall effective rate of Kampo medicines in tinnitus was 38.4% and increased to 64.6% after including effects for the accompanying symptoms (e.g., dizziness, insomnia, and headache). Hangekobokuto was prescribed most frequently. The effective rate for hangekobokuto in tinnitus was 32.1% and significantly increased when it was used in combination with a herb, chotoko (Hook of Uncaria, rhynchophylla Miquel) (p < 0.05, Fisher's exact test). The effects and modern pharmacological action of chotoko indicate that it may be effective for tinnitus. Given that tinnitus was intractable in study subjects who had been treated using other therapy approaches earlier (84% of the population), the findings indicate that Kampo medicine may be partially effective for tinnitus.

<b>The Current Kampo Education Situation at 80 University </b><b>Faculties of Medicine </b> / 日本東洋医学雑誌

Background : Kampo, or traditional Japanese medicine education, was accepted into the education system after a new requirement of being able “to roughly explain Wakan (Japanese/Chinese) medicines" was added to the core curriculum model.<br>Purpose : Kampo medicine has been taught at all 80 medical schools and universities since 2007. We con ducted a nationwide survey to understand the present situation, gain insights from several Kampo education viewpoints, and elucidate any challenges for the Japan Society for Oriental Medicine (JSOM) in future.<br>Method : A postal questionnaire survey was sent to 80 medical schools and universities from the Liaison Committee of JSOM.<br>Results : 67 out of the 80 medical institutions (83.8% return rate) responded to the survey. The answered survey results were as follows : Kampo medicine is needed in regular clinical practice (91%), studies are needed to evaluate the outcome of Kampo Medicine education (77%), and dedicated staff members are being trained (46%).<br>Conclusions : Further development of graduate education and its standardization as well as improvement of bedside training is needed for Kampo education. In addition, establishment of a post-graduate Kampo education system will be crucial in the future.

Efficacy of Takushato on Patients with Dizziness and Vertigo in Relation to Signs and Symptoms of Fluid Retention / 日本東洋医学雑誌

Takushato is a Kampo formula used for the treatment of dizziness and vertigo. Signs and symptoms suggestive of fluid retention have been regarded as clinical indications for takushato administration, but it is not clear if improvement of these signs and symptoms is related to the clinical efficacy of takushato, so we analyzed the correlation among these factors. Twenty patients who suffered from dizziness and vertigo were treated with takushato for 4 weeks. Before and after treatment, subjective symptoms and objective data including vestibular function tests were assessed, and correlation among the factors was analyzed. Improvement of patients' total symptoms was significantly correlated with improvement of fluid retention scores. Furthermore, improvement in vestibular function tests showed a trend toward correlation with that of fluid retention scores.These results suggest that improvement in the signs and symptoms of fluid retention is related to the clinical efficacy of takushato. We conclude that the presence of fluid retention is a reasonable clinical indication for takushato administration.

Assessment of the Satisfaction of Patients of Atopic Dermatitis with Kampo Therapy / 日本東洋医学雑誌

The patient with atopic dermatitis is often dissatisfied with the long-term nature of treatment for his/her disease. The aims of this study were to examine the effect of Kampo therapy on the skin manifestation of atopic dermatitis as well as the patient's mental state, and to evaluate the relation between severity of symptoms and satisfaction with the Kampo therapy. Kampo medicine was administered to 15 in-patients with atopic dermatitis for 6 months. Their clinical conditions, quality of life (QOL) assessments, and psychosomatic scores before and after treatment were observed and comparatively evaluated. We evaluated patients' symptom severity with the atopic dermatitis severity classifications of the Japanese Dermatological Association, and the European SCORAD (Scoring of Atopic Dermatitis). We evaluated QOL with the SF-36 and DLQI (Dermatology Life Quality Index), and mental state with the PSS-AD (Psychosomatic Scale for Atopic Dermatitis). Clinical conditions, QOL and mental states were improved after treatment with Kampo medicine. However, when we examined individual cases, severity of symptoms and satisfaction with treatment did not correlate. Patients' satisfaction ratings and the severity of their symptoms do not necessarily correspond in patients with atopic dermatitis, because evaluations vary with each individual. Therefore, clinicians treating patients for atopic dermatitis must make an effort to recognize each patient's psychological condition.

Four Cases of Male Patients Successfully Treated with Tokishakuyakusanryo / 日本東洋医学雑誌

Tokishakuyakusan has been used widely to treat various diseases including gynecological disorders. Currently, tokishakuyakusan is frequently used to treat female patients, while indications for use in male patients are unclear. Furthermore, there are few reports of male patients having been effectively treated with tokishakuyakusan or tokishakuyakusanryo. Here, we report four male patients successfully treated with tokishakuyakusanryo. Case 1 was an 84-year-old man who had uncontrolled nasal allergy, and treatment with tokishakuyakusanryo was effective in relieving the patient's allergy symptoms that were accompanied by chills and oketsu (blood stasis) findings. Case 2 was a 63-year-old man whose chief complaints were bronchial asthma, benign prostate hypertrophy, and nasal allergy. All his symptoms improved considerably with tokishakuyakusanryo and hangekobokuto, especially the symptoms of nasal allergy. Case 3 was a 70-year-old man whose chief complaint was persistent proteinuria. Tokishakuyakusanryo was prescribed, in consideration of his clinically observed condition, which included sensitivity to cold, blood stasis and fluid retention. His proteinuria disappeared four months later, along with his other complaints of chills, oketsu, and fluid retention. Case 4 was a 56-year-old man whose chief complaint was ulcerative colitis. He had responded well to treatment with ifuto, but he developed hypertension. His prescription was changed to tokishakuyakusanryo, a similar prescription that does not contain the Glycyrrhiza radix which can cause hypertension. Afterwards, his blood pressure decreased to normal levels and his abdominal symptoms remained stable. Nangai Yoshimasu published the opinion that tokishakuyakusan could be applied not only in female patients but also male patients. Additional reports on male cases would provide helpful information to clarify tokishakuyakusan indications in male patients.

Clinical Analysis of Cases with Drug-induced Liver Injury for Kampo Medicine / 日本東洋医学雑誌

We analyzed the clinical features of 21 cases with drug-induced liver injury due to Kampo medicines between the years 2000 and 2009 in our institute. The mean age in these cases was 55.2 ± 13.4 years. Five of the cases were men, and 16 were women. In 17 of the 21 cases, drug-induced liver injury had occurred within 3 months after beginning Kampo medicines. There were no subjective symptoms in 11 cases. Nine cases of both hepatocellular injury, and of mixed-type injury were seen. Causative Kampo medicines included an Ogon (<I>Scutellariae Radix</I>) component in 19 cases. A drug-induced lymphocyte stimulation test (DLST) was performed in 5 cases. The test was positive for Kampo medicines in only one of the 5 cases. Liver injury improved or normalized in 18 cases (85.7%) after discontinuing causative Kampo medicines. In another 2 cases, liver injury normalized after changing a Kampo medicine to the same prescription without Ogon. These results suggest that even if patients complain of no symptoms we must perform blood tests to check liver function within 3 months of prescribing Kampo medicines, especially those including Ogon, to facilitate early diagnosis of drug-induced liver injury.
