BACKGROUND/AIMS: Solifenacin, a muscarinic type 3 receptor antagonist, is used to treat overactive bladder in adults. The aim of this study is to examine the efficacy of solifenacin on the symptomatic relief of diarrhea predominant irritable bowel syndrome (IBS-D). METHODS: A total of 20 patients with IBS-D were enrolled. After a 2-week observation period, all participants received solifenacin for 6 weeks. Subsequently, the administration of solifenacin was discontinued and ramosetron, a serotonin 3 receptor antagonist, was administered for 4 weeks. Overall improvement, the IBS-symptom severity scale (IBS-SSS), and frequency of defecation were assessed. RESULTS: Six weeks after initiation of solifenacin treatment and 4 weeks after initiation of ramosetron treatment, overall improvement was observed in 19 out of 20 (95%) and 17 out of 20 (85%) participants, respectively. At 2 weeks after initiation of solifenacin, overall improvement was observed in 16 out of 20 participants (80%). Total IBS-SSS scores at 2 and 6 weeks after the administration of solifenacin, and at 4 weeks after administration of ramosetron, were significantly lower than those at week 0. Compared to before administration, the participants' quality of life and frequency of defecation were significantly lower in all participants at 2 and 6 weeks after the administration of solifenacin and at 4 weeks after administration of ramosetron. CONCLUSIONS: The efficacy of solifenacin in the treatment of IBS with diarrhea was not inferior to that of ramosetron. Further placebo-controlled parallel studies are needed.

Tokishakuyakusan is well-known to be useful in infertility. We report 3 cases of infertility that resulted in pregnancy and childbirth due to oral administration of tokishakuyakusan after being led to tokishakuyakusan pattern by symptomatic treatment resolving blood stasis or regulating qi. Case 1 was a 39-year-old woman with unexplained infertility. She visited our hospital because of irritability and was initially administered keishibukuryogankayokuinin and yokukansankachinpihange, and then tokishakuyakusan. After a month of treatment, she conceived. Case 2 was a 33-year-old woman who was diagnosed with ovarian dysfunction and received ovarian stimulation. To support infertility therapy she was administered keishibukuryogan, and subsequently, tokishakuyakusan based on her pattern. After 3 months of treatment, she conceived. Case 3 was a 37-year-old woman who was diagnosed with unexplained infertility and was administered kamishoyosan and hochuekkito for premenstrual syndrome at another hospital. She visited our hospital because of sensitivity to cold and fatigability. The previous treatment was discontinued, and she was administered tokishakuyakusan based on her pattern. After 2 months of treatment, she conceived. All 3 patients continued tokishakuyakusan treatment during pregnancy and successfully delivered live babies. These 3 cases initially received other Kampo medicines and then, tokishakuyakusan, according to the changed Kampo medical pattern. It is important to administer tokishakuyakusan to patients with infertility, following administration of appropriate Kampo medicine to correct their imbalance of qi, blood and fluid and after further confirming the abdominal signs suitable for tokishakuyakusan.

Three patients with hypersensitivity pneumonitis caused by inhalation of spores of Cortinus shiitake (Lentinus edodes) cultivated in vinyl houses were observed. These three patients developed the disease after harvesting shiitake for several hours in closed frame houses with a heater in the autum and winter. The frames were full of spores of shiitake and the patients suffered from a discordant feeling, systemic weakness, a feeling of cold, fever (over 38 C), a feeling of airway occlusion, a slight cough and sputum. These symptoms disappeared during rest the next day.
Case 1 was examined by the inhalation provocation test with a suspension of shiitake spores and spore-allergen. This test caused several clinical symptoms (fever, airway occlusion and various symptomatic feelings), leucocytosis, decrease of PaO₂ a positive reaction of CRP and X-ray findings (appearance of interstitial pneumonitis shadows).
The 3 patients were considered to be suffering from allergic hypersensitivity pneumonitis due to inhalation of spores of Cortinus shiitake, because of their work, the development of symptoms after work in specific occupational conditions, a positive reaction to precipitating antibody against spore-allergen of shiitake, negative reactions to precipitation antibodies to 11 molds-allergens, various abnormal values in immunological tests and a positive reaction in a provocation test in one case.
In a survey of 45 shiitake-grower, it was found that 6 (13.3%) suffered from respiratory disease. No difference was found in the incidence of intracutaneous reactions to spore-allergen or allergen of dried shiitake in non-farm workers. Among 31 growers of shiitake a precipitation antibody to spore-allergen was observed only in these three patients. These results indicate that an allergic disposition is very important for development of hypersensitivity pneumonitis.

De Quervain disease and carpal tunnel syndrome are major problems that occur after delivery. During pregnancy, hormone confusion readily causes inflammation of tendons ;furthermore, overuse of hands during care of other children contributes to symptom onset. We report four cases of de Quervain and carpal tunnel syndrome occurred after delivery. All patients were women, aged 33-­39 years. All patients breast-­fed after birth. One patient was diagnosed with de Quervain disease, two were diagnosed with carpal tunnel syndrome, and one was diagnosed with de Quervain disease accompanied by carpal tunnel syndrome. All patients received tokishakuyakusan ;thereafter, their pain decreased, but slight numbness from the carpal tunnel syndrome remained. Drugs that can be used during breastfeeding are limited ;however, tokishakuyakusan can be prescribed safely and effectively.

Globally, there are currently three major competency models for healthcare professions education: CanMEDS 2015 in Canada, Accreditation Council for Graduate Medical Education Six-Competency model in the United States, and Tomorrow's Doctors in the United Kingdom. An investigation by the Revision Committee for the Japanese National Model Core Curriculum revealed that these competency models had been utilized in seven countries. In each country investigated for revision, medical schools were allowed to implement these major competency models flexibly. Although each university has a high degree of freedom in curriculum design and educational delivery, each country is regulated by a quality assurance system that requires accreditation by the World Federation for Medical Education (WFME) and other organizations. The 2022 Revision of the Japanese National Model Core Curriculum has also been translated into English and released to the global audience in the field.
