We analyzed dispensing receipt data in the medical treatment in October 2019 using the Receipt Information/Specific Medical Examination Information National Database (NDB), extracted the cases of multiple combinations of Kampo prescriptions, and analyzed their frequencies. Of the 536,524 receipts, 44,731 (8.3%) included Kampo and non-Kampo crude drug preparations. Of the receipts that included Kampo and non-Kampo crude drug preparations, 38,032 receipts (7.1%) included single Kampo or non-Kampo crude drug preparation. There were 6,699 receipts (1.2%) that included multiple Kampo and non-Kampo crude drug preparations. There were 187 receipts for the decoctions containing multiple rude drugs without Kampo preparations, and the ratio was 0.035% of all receipts and 0.42% of the receipts containing Kampo and non-Kampo crude drug preparations. There was one receipt containing eight Kampo preparations, three receipts containing seven Kampo preparations, and a total of 84 receipts containing five or more Kampo preparations. Although it is unclear how many multiple Kampo preparations were prescribed at the same time, this investigation indicates the actual duplication of multiple Kampo preparations.

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).

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.

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.

Abdominal distension is one of the common symptoms and can cause abdominal pain and anorexia, which may raise adverse effect on general well-being and quality of life. In Western medicine, there are specialized treatments for structural lesions associated with abdominal distension, but functional abdominal distension is often difficult to treat. There have been some reports of Kampo medicine for treatment of abdominal distension, but no case reports on tokishigyakukagoshuyushokyoto. We experienced two cases of abdominal distension successfully treated with tokishigyakukagoshuyushokyoto. Case 1 was 86-year-old woman who developed abdominal distension with frequent belching. Case 2 was 59-year-old man who developed abdominal distension associated with opioid. Regulating qi medicine was not effective for abdominal distension in both cases. Both cases had reversal coldness of the extremities, tympanic sounds of abdomen, coldness of abdomen, and inguinal tenderness and resistance. Therefore, we diagnosed them as tokishigyakukagoshuyushokyoto sho. After administration of tokishigyakukagoshuyushokyoto, in Case 1, the frequency of belching decreased and the appetite increased with the improvement of abdominal distension. In Case 2, increasing the dose of goshuyu in tokishigyakukagoshuyushokyoto relieved abdominal distension. Tokishigyakukagoshuyushokyoto can be effective for abdominal distension with interior cold pattern.

The Medical Safety Committee has conducted various activities for patient safety in Japanese traditional Kampo medicines. In this study, we conducted a questionnaire survey to promote the prevention of medical accidents and their recurrence. We received responses from 15 of 19 facilities specializing in Kampo medicine and collected a total of 247 incident and accident cases in the field of Kampo medicine. Cases of side effects included interstitial pneumonia caused by Kampo prescriptions containing Scutellariae Radix, aconite poisoning, and licorice-induced pseudoaldosteronism. Furthermore, we also collected decoction-specific cases, which are unique to facilities specializing in Kampo medicine, for the first time. From the results, we included the following seven points for risk management in the field of Kampo medicine : 1) insufficient recognition to the side effects of Kampo medicines, 2) misunderstanding of the dosages of Kampo products, 3) errors due to similarities in Kampo formulas and crude drug names, 4) preconception of frequently used Kampo prescriptions, 5) contamination in the decoctions, 6) errors related to crude drug items and their dosages that are frequently added or subtracted, 7) errors in hospital wards.

Persistent or intractable hiccups worsen the activity of daily life and the quality of life of patients, but are sometimes difficult to treat. There are no recommended therapies in Western medicine for hiccups, and Kampo medicine can often be used. However, there have been no case reports on keishininjinto for hiccups. We experienced two cases of hiccups successfully treated with keishininjinto. Case 1 was a 68-year-old man who continued intractable hiccups for 3 years. Case 2 was an 81-year-old man who developed persistent hiccups during mechanical ventilation. Both cases had spontaneous sweat, tendency of diarrhea, epigastric discomfort and resistance, and cold of epigastrium, so we diagnosed them as keishininjinto-sho. It took 6 months to improve hiccups after administration of keishininjinto in case 1 and 1 week in case 2. Keishininjinto can be effective for hiccups with interior and cold pattern.

We report a case of severe headache associated with cerebellar infarction was successfully treated with Kampo therapy. The patient complained of severe headache and vertigo in spite of standard therapy after the decompression craniectomy. However, his symptoms were relieved immediately by administration of goreisan. The pharmacological effect of Kampo formulation i.e. goreisan is still unknown, but this formulation has been used for headache with edema, vertigo and vomiting. According to the classic textbook, this formulation has a potential to improve water imbalance in the body, including brain edema. This Kampo medicine is seemed to be an alternative to manage such patients.

The authors experienced two cases of trigeminal neuralgia successfully treated by a Kampo formulation tokishigyakukagoshuyushokyoto (TSG). Case 1 is 70-year-old woman who complained of severe pain on the right side of her face. She was administered carbamazepine. It was effective for the facial pain but she could not take it continuously because of side effect, namely ataxia. Therefore, we tried to administer TSG. This Kampo formulation proved effective, and her pain was controlled without carbamazepine. Case 2 is 69-year-old woman who complained of localized pain on the right side of her face. In this case TSG alone was effective.

The Medical Safety Committee analyzed the case reports of minor incidents from the pharmacies last time as part of an activity to promote patient safety in Japanese traditional Kampo medicine. This time, we analyzed the case reports of medical accidents and minor incidents from the medical institutions. We extracted 626 reports related to Kampo products from the public database, which the Japan Council for Quality Health Care has established based on the collected information related to the medical accidents and minor incidents. The medical accident information includes case reports related to drug-induced liver injury. The minor incident reports include prescribing error due to misinterpretation related to the quantity of one sachet of Kampo extract product, dispensing error due to similarity of product appearance, number or name, and administration error due to judging the medicine only by Kanji characters or product company names without checking the Kampo formula name. Additionally, the minor incidents were often discovered by people belonging to different professions or patients themselves. In order to promote patient safety, knowledge about these incidents should be shared among the people involved in the same or different professions.
