At the 71st Annual Meeting of the Japan Society for Oriental Medicine held in August 2021, we performed a special program focusing on education in Kampo medicine, “Pre-graduation and post-graduation education in Kampo medicine for the next generation.” As a part of this project, we constructed the “Common Kampo test” based on the “Standard lectures on Kampo” as a web-based test using Moodle, and then the test was conducted in the form of a web test with 163 participants. The commentary of the “Common Kampo test” was live-streamed and was viewed by many participants, including students, educators and academics from all over Japan. In this paper, we report on the series covering the construction of the web system, creation of questions, answer results, and commentary on answers. With the recent popularization of tablet devices and smartphones, this web-based test system has the potential to become a scientifically based and optimal learning system not only for students but also for medical professionals such as doctors, pharmacists, and nurses.

Laryngeal venous malformation has a risk of airway obstruction due to its enlargement or bleeding. It requires treatment such as sclerotherapy, laser treatment or surgery. However, adult-type laryngeal venous malformation occurs frequently in the upper part of the glottis, and causes almost no symptoms except when it occurs in the vocal cords. So some patients do not wish to undergo surgery. This time, we describe a case of an asymptomatic laryngeal venous malformation patient who did not wish to receive laser treatment, and was significantly improved by Kampo medicine. The patient was a 69-year-old man. He consulted us because of an accidental laryngeal mass on upper gastrointestinal endoscopy during a medical examination, but he had no particular pharyngeal symptoms. A venous malformation was found in the upper part of the right glottis, and we recommended him laser treatment. But he did not wish it because he had no symptoms. We considered the condition of static blood (oketsu), and administered keishibukuryogan for 7 weeks, but there was no change. Since he had constipation, we administered daiokanzoto together with keishibukuryogan, and his bowel movement improved. Thirteen weeks after the beginning of the combined use, the venous malformation also remarkably reduced.

We herein report a patient who complained persistent exudate at navel in spite of adequate antibiotics therapy after laparoscopic cholecystectomy was successfully treated with Kampo therapy. The pharmacological effect of this Kampo formulation i.e. senkinnaitakusan is still unknown, but this formulation has been used for persistent infectious diseases. According to the description in the classic textbook, this formulation is suggested to encourage metabolic function and exhibit anti-inflammatory function. There have been no reports of Kampo therapy for the superficial incisional site infection associated with laparoscopic surgery. The authors propose that Kampo medicine is another promising option in the management of surgical site infection (SSI).

Asthma attack difficulty breathing rapidly worsens the condition over time. Especially when the condition worsens before surgery, general anesthesia (GA) may be indicated depending on the type of surgery. In Japan, there is a tendency to avoid GA in cesarean section (C/S) due to the risk of difficult intubation, adverse effects on the fetus, and concerns about resuscitation of the newborn. This time, foreign body sensation in the throat (baikakuki) was found in a case of asthma-like attack accompanied by difficulty breathing caused by disturbance symptoms on the day of C/S and in a case of difficulty breathing due to preoperative antibiotic intravenous drip. After oral administration of hangekobokuto to the patients, dyspnea disappeared in either case, and I was able to avoid GA and perform C/S with combined spinal-epidural anesthesia. Considering asthma in Kampo medicine, it is thought that psychoactive predispositions such as anxiety and impatience are the triggers that cause qi counter flow and qi stagnation, which causes phlegm to condense, resulting in baikakuki and symptoms. Therefore, it was thought that hangekobokuto, which remove phlegm, was adapted.

A 64 year-old female presented with fever and cough. She had suffered from a cough for one day and we treated her with saikokeishito. However, her symptoms got worse and she developed chest pain. She was diagnosed with bacterial pneumonia at another clinic and she was referred to our hospital 3 days after starting saikokeishito. Her X-ray showed right infiltration in her lung and her blood examination had signs of inflammation. Pneumonia with pleuritis was suspected, but she was allergic to antibacterial drugs and hoped to continue Kampo treatment. We switched saikokeishito to saikanto. Her chest pain decreased soon after taking saikanto and 4 days later only a slight cough remained. Eleven days later, her inflammatory reaction improved. Kampo formulas containing Bupleuri radix are usually selected for pneumonia or pleuritis according to a patient' s pattern identification. We gave her saikanto, a mixture of shosaikoto and shokankyoto, because she had chest pain. Saikanto was significantly effective. There have been few clinical reports about treatment for pneumonia with Kampo medicine alone without using antibacterial drugs. We believe this case shows that Kampo treatment is effective for pneumonia and pleuritis.

Hangekobokuto is often used for globus sensation. We herein describe two cases in which ryokeijutsukanto was effective for globus sensation, for which hangekobokuto was ineffective. Case 1 was a 28-year-old woman. She had been suffering from postprandial belching, fullness and stuffy throat for a year. She underwent examination, but could not find the cause of her symptoms and visited our department. She was prescribed hangekobokuto, but the feeling of stuffiness in her throat did not improve. Case 2 was a 50-year-old woman. She had been afflicted with a feeling of fullness in the ears, tinnitus, and pain in the back of the eyes for two weeks. She visited the otolaryngology department, but no abnormalities were found so she visited our department. She was prescribed kamishoyosan, and although her ear fullness and tinnitus improved by about 60%, she began to complain of dizziness and throat stuffiness. This did not improve even though she used hangekobokuto with kamishoyosan. In both cases, after changing treatment to ryokeijutsukanto, the symptoms were improved. For globus sensation, it is necessary to select Kampo medicines while paying attention to qi deficiency, qi depression, qi counter flow, static blood, liver depression, lack of fluid, fluid toxicity, and gastrointestinal disorders. We thought that ryokeijutsukanto could be a candidate.

We herein report three patients who complained atypical febrile diseases associated with painful whole body (Case 1), general fatigue (Case 2), and a sense of general discomfort (Case 3). All cases were not accompanied by dizziness and a shaky feeling which are commonly associated in shimbuto-sho i.e. indication of shimbuto, but presented severe tenderness at the left paraumbilical region which was suggested as indicative point of shimbuto by Yoshiko Takagi. We made a diagnosis in these three cases as shimbuto-sho based on the Takagi's tender point. Through these clinical experiences we propose that a new type of shimbuto-sho, which are completely different from the fixed idea of inherited knowledge. This new type of shimbuto-sho consists of following signs ; fever with chill, floating and feeble pulse, no sweating, general fatigue or body pain, and severe pain at Takagi's tender point.

Here we report 3 cases of advanced cancer using multidisciplinary treatment including reibaisan (WTMCGEP, a dry extract of Wisteria floribunda, Trapa natans, Myristica fragrans, Coix semen, Ganoderma lucidum, Elfvingia applanata, Punica granatum). Case 1 : 87-year-old man, suffering from stage IV esophageal squamous cell carcinoma (ESCC) with aortic and bronchial invasion, was referred to our clinic for palliative care. He had radiotherapy and chemotherapy. Only one course of chemotherapy was performed due to its intolerable side effects. The treatment with reibaisan started 11 months after the diagnosis. ESCC disappeared after 17 months of reibaisan treatment, and no relapse was observed for 66 months after the diagnosis. Case 2 : 79-year-old man, suffering from stage III ESCC, was initially scheduled for surgery after preoperative chemotherapy. Only one course of preoperative chemotherapy was performed because of its intolerable side effects. Therefore, radiotherapy combined with reibaisan followed. ESCC disappeared 6 months later, and no relapse was observed for 33 months after the diagnosis. Case 3 : 73-year-old woman, suffering from stage IV pancreatic cancer with systemic metastasis (brain, lung, and peritoneum). She initially showed Trousseau syndrome and was treated with low-molecular-weight heparin for multiple cerebral infarctions. One-month palliative chemotherapy and reibaisan resulted in a rapid reduction of ascites and improvement of neurological symptoms. Her progression-free survival period was 7 months. She lived 13 months thereafter. This suggests that reibaisan, which contains crude drugs that have been shown to have antitumor effects, may be another promising treatment for advanced cancers.

Here, we report a case of nocturnal enuresis persisting into adulthood treated with Kampo medicine. A 21-year-old woman had a history of nocturnal enuresis every night during childhood and once every 2-3 nights during school age. Although the frequency of urinary incontinence decreased to 1-2 times/week at 19 years of age, nocturnal enuresis persisted into adulthood. She was diagnosed with mild strain of the rectus abdominis muscles and palpable abdominal aortic pulsation above the umbilicus, and keishikaryukotsuboreito (decoction) therapy was initiated. She did not experience urinary incontinence at night for 3 weeks, except for one episode immediately after treatment commencement. She tended to urinate only 4 times from the time she awoke until bedtime ; therefore, we added a small amount of goreisan to her treatment regimen to increase the urinary output and daytime frequency of urination. The frequency of urination increased from 4 to 7 times and stabilized. We discontinued goreisan administration 2 months later, and keishikaryukotsuboreito monotherapy was continued. We did not observe recurrent nocturnal enuresis and, therefore, switched the decoction to an extract. After the symptom stabilized, the dosage of keishikaryukotsuboreito was reduced by half. Nocturnal enuresis occurred only once when the patient missed a dose for 3 consecutive days but did not recur for over 4 months after strict adherence to medication. This case report highlights the role of Kampo therapy as an effective therapeutic option for nocturnal enuresis persisting into adulthood.

We herein report a 36-year-old male patient, who complained of persistent and recurrent nausea with vomiting for 16 years in spite of various standard treatments, was successfully treated with Kampo formulation Shimbuto, which selected based on the left para-navel tender point. We speculated that the clinical disorder in this case was related to suitai i.e. water imbalance syndrome in Kampo medicine. However, there has never been such a case report in the field of Kampo, and no related papers have been found in the standard database Medline. We believe this report is valuable from the viewpoint of therapeutics in both Western and Kampo medicine.

Prolonged cough in coronavirus disease 2019 (COVID-19) is not only uncomfortable for patients, but also prolongs the length of stay in an isolation facility. This results in delays in patients' return to their daily life. Therefore, the prompt treatment of cough is important. In this report, we used Japanese traditional (Kampo) medicine, chikujountanto for the treatment of cases with residual cough, airway secretions, slight fever, anxiety, and insomnia, several days after the onset of coronavirus. From October 2020 to September 2021, we prescribed chikujountanto for thirty-three COVID-19 patients with prolonged cough in an isolation facility. Seven patients (6 women and 1 man with ages ranging 37-70 years) were treated with no other medication. Comorbid symptoms included slight fever, sputum, sore throat, nasal discharge, headache, anxiety/insomnia, and taste/olfactory disorders. The start date of treatment ranged from 9 to 21 days after the onset of COVID-19, and the time until cough and comorbid symptoms improved to values less than NRS 2 or less, was 2 to 6 days after treatment. Three patients had persistent cough and needed to switch to other medication. In COVID-19, chikujountanto may be useful for coughing during the period when the peak of the viral proliferative phase has passed but airway inflammation is still present.

We verified the educational outcomes and effects of the practice of Problem-based learning (PBL) on the theme of Kampo medicine and the continuous academic support. From 2013 to 2021, we conducted Kampo PBL for second-year medical students, and compared the results of Kampo exams in the fourth year between Kampo PBL participants and non-participants. Moreover, the learning obtained through subsequent academic activities was extracted from their free-form text. Kampo PBL was performed for a total of 26 groups. Participants who underwent Kampo PBL (n = 72) scored significantly higher than those who did not (n = 734) (p<0.05). In addition, academic support resulted in 5 academic presentations in an academic conference and 3 articles published in academic journals. The lessons learned included “concretization of understanding of Kampo medicine,” “valuable experience in academic activities,” and “promoting motivation and its impact on the future.” Kampo PBL improved knowledge about Kampo medicine, and academic activities cultivated the research mind.

Team-based learning (TBL) is an educational method developed to cultivate the ability to solve problems by learning and applying knowledge on one's own, as well as the ability to make decisions, take responsibility, and collaborate by working on issues in small groups. TBL in Kampo medicine was held as a special program : active learning at the 71st Annual Meeting of the Japan Society for Oriental Medicine. A total of 57 students participated in the TBL session. The theme of the session was the common cold with the theory of yin and yang. According to the results of a questionnaire survey, the students answered that they were able to understand the flow of diagnosis in Kampo medicine, which was the goal of the course. As a bridge from classroom lectures to clinical practice, TBL in Kampo medicine was considered to be useful in Kampo medical education.

We report a case of elderly COVID-19 pneumonia successfully treated with kakkonto in combination with shosaikotokakikyosekko confirmed by chest CT. The patient was an 82-year-old woman who complained fever, appetite loss and general fatigue. Her SARS-CoV-2 PCR showed positive and chest CT films showed pneumonia. She refused hospitalization and underwent medical treatment at home. We administered kakkonto in combination with shosaikotokakikyosekko. After 3 days, her fever decreased, and after 9 days, her subjective symptoms and pneumonia shadow on chest CT films markedly improved. Chest CT confirmed that the combined use of kakkonto and shosaikotokakikyosekko was also effective in elderly patients with COVID-19 pneumonia.

A 47-year-old woman with body temperature 35.6 ℃ took the 3rd COVID-19 vaccine shot at our clinic on Day 1. Since she felt chills and suffered from genital bleeding on Day 3, she visited our clinic to take a gynecological examination. Her temperature was 37.1 ℃ at that time. On Day 15, she suffered sustained symptoms of chills and general fatigue, and she went to another internal medicine clinic to take a medical care. However, her condition was unexplained and she was referred to a general hospital. On Day 16, she came to our clinic to confirm results of the gynecological examination. Her symptoms persisted even though the data showed no problems, so we prescribed her saikokeishikankyoto (SAKK) for only 3 days. On Day 19, SAKK dramatically improved her symptoms. On Day 37, her temperature was 36.2 ℃ without any symptoms.
