Introduction: The purpose of this study was to identify factors affecting the length of hospitalization of elderly patients with urinary tract infection (UTI) in an acute care hospital, where general practitioners treat the majority of them.Methods: Subjects were patients aged ≥ 65 years with UTI who were admitted to our hospital between April 2019 and March 2021. The primary endpoint was the length of hospital stay on an acute care ward. Factors associated with the primary endpoint were detected using logistic regression analysis with several explanatory variables (patients' baseline characteristics, laboratory findings, and interventions during hospitalization).Results: In total, 143 cases were eligible for analysis (88±7 years old, 37% male). Multivariate logistic regression analysis revealed that: Charlson Comorbidity Index ≥ 6, complex UTI with urologist's assessment, and the score of the Functional Oral Intake Scale (FOIS) on admission were significant factors correlated with the length of hospitalization (odds ratios: 5.07, 0.13, and 0.30, respectively).Conclusion: In older patients with UTI, CCI≥6, UTI without urologist's assessment, and a lower score of FOIS may prolong the length of stay in an acute care hospital.

A 66-year-old woman presented with a choking feeling in her throat. She was hospitalized three times and started nasogastric tube feeding one year before. She was diagnosed as somatic hallucination by a psychiatrist and started antipsychotic medication. She was admitted to our department in September due to worsening of choking sensation. Her body weight was 29 kg, and she was significantly lethargic and undernourished, and had difficulty in moving, parkinsonism, cognitive dysfunction, and apathy. She was considered to be in late yin stage pattern and started on tsumyakushigyakuto, which enabled her to walk with a walker, but her choking sensation did not improve. Two days after the conversion to yokukansankachimpihange, her speech and smile increased, and her motivation improved. After the switch to the extract of yokukansankachimpihange, the fullness and discomfort in left chest and hypochondrium disappeared, and she was able to take jelly and walk by herself. She was transferred to other hospital in January of the following year. Three months after the transfer, she was able to take enteral nutrition by herself and her weight increased to 37 kg. Eight months later after the transfer, she was able to take solid food orally and her weight increased to 41.5 kg. Yokukansankachimpihange may be useful for treating the patients with somatic hallucination and apathy.

We have previously reported on a predictive model for deficiency-excess pattern diagnosis that was unable to predict the medium pattern. In this study, we aimed to develop predictive models for deficiency, medium,and excess pattern diagnosis, and to confirm whether cutoff values for diagnosis differed between the clinics. We collected data from patients' first visit to one of six Kampo clinics in Japan from January 2012 to February 2015. Exclusion criteria included unwillingness to participate in the study, missing data, duplicate data, under 20 years old, 20 or less subjective symptoms, and irrelevant patterns. In total, 1,068 participants were included. Participants were surveyed using a 153-item questionnaire. We constructed a predictive model for deficiency, medium, and excess pattern diagnosis using a random forest algorithm from training data, and extracted the most important items. We calculated predictive values for each participant by applying their data to the predictive model, and created receiver operating characteristic (ROC) curves with excess-medium and medium-deficiency patterns. Furthermore, we calculated the cutoff value for these patterns in each clinic using ROC curves, and compared them. Body mass index and blood pressure were the most important items. In all clinics, the cutoff values for diagnosis of excess-medium and medium-deficiency patterns was > 0.5 and < 0.5, respectively. We created a predictive model for deficiency, medium, and excess pattern diagnosis from the data of six Kampo clinics in Japan. The cutoff values for these patterns fell within a narrow range in the six clinics.

Uzushakusekishigan is a Kampo formula described in ‘Jin Gui Yao Lue' for treatment of “heart pain that spreads out to the back, or back pain that spreads to the heart.” We successfully treated three patients with this formula. Patient 1 was a 53-year-old man suffering from precordial pain which occurred after amputation of the right forearm;patient 2 was a 46-year-old man with epigastralgia that occurred after taking cold meals;and patient 3 was a 28-year-old woman suffering from epigastralgia accompanied with panic disorder. Epigastric discomfort and resistance occurred in all three cases, prompting us to prescribe this formula. There are few reports of successful application of uzushakusekishigan, and it is not clear what symptoms and pathologies are relevant when prescribing this formula. However, our findings strongly suggest that uzushakusekishigan should be considered when treating severe chest or abdominal pain.

We report a case of panic disorder treated with keishikyokeikabukuryobyakujutsuto. The patient was a 42-year-old woman who had one or two episodes of panic attacks every month for 1 year accompanied by dyspnea, fear, rigidity of hands, etc. The episodes were more frequent with physical exertion and menstruation and did not improve with kamishoyosan or kanbakutaisoto. Then, after a car accident, she had a panic attack with a stronger intensity. Blood and imaging examinations revealed no special findings, and we diagnosed her with panic disorder. We considered her complaint as Honton disease and administered ryokeikansoto. After 2 weeks, her mental condition improved, and dyspnea and fear of attacks relieved. After 2 months, office work became more strenuous, and attacks recurred once or twice a week. An abnormal sensation of the posterior cervix occurred as a prodrome of an attack, and simultaneously, she noticed neck stiffness. After switching to keishikyokeikabukuryobyakujutsuto, the cervical sensation disappeared, neck pain and neck stiffness were relieved, and the attacks did not reappear. This case suggested that keishikyokeikabukuryobyakujutsuto was useful for the prevention of panic attacks associated with neck stiffness.

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.

An eight-year-old girl was referred and admitted to our hospital with the chief complaint of purpura on her lower legs. Blood tests revealed pancytopenia, and bone marrow findings showed marrow hypoplasia. Refractory cytopenia of childhood (RCC) was diagnosed based on the central diagnostic system of the Myelodysplastic Syndrome Committee of the Japanese Society of Pediatric Hematology. Immunosuppressive therapy was performed with the administration of rabbit antithymocyte globulin, methylprednisolone and cyclosporin A,but it was not effective. Eight months after admission to our hospital, Kampo treatment was started based on traditional Kampo diagnosis. After treatment with oral administration of kamikihito and kyukikyogaito, her pancytopenia gradually improved. Erythrocyte transfusion was discontinued after 2 months, and concentrated platelet transfusion also became unnecessary after 3 months. As a result of improvement in pancytopenia, her white blood cell count, hemoglobin value, and platelet count reached almost normal levels after 16 months. The scheduled bone marrow transplantation was canceled. The action mechanisms of kamikihito and kyukikyogaito for RCC are not clear, and their effective rates are also unknown. However, Kampo treatments are less invasive, inexpensive, and have few side effects. We believe that Kampo medicine is a therapeutic method that should be actively attempted in cases of RCC with poor response to standard treatment.

We have developed and operated a browser-based questionnaire system for Kampo medicine based on conventional questionnaires and review of systems to reveal implicit Kampo wisdom both in patients' questionnaire data and in some Kampo specialists' examination data. However, the questionnaire data were found to be inaccurate because too many questions were included and cumbersome input steps were required. The purpose of the present study was to solve these problems and to develop a new patient-centered questionnaire system with fewer questions and an easier input method. After analyzing inquiry database from collaborating institutes and hospitals, we deleted, combined, and added questions. We changed the evaluation method of symptoms from a visual analogue scale to a simple staged evaluation, and introduced another method to evaluate the main symptoms in each time of visit using a visual analogue scale. At the same time, a tool for predicting Kampo pattern diagnoses based on the questionnaire data was implemented. We have already started collecting more accurate and reliable data using the new questionnaire system. It is expected to support routine practices and facilitate more precise clinical research on Kampo medicine.

The patient was a 49-year-old woman. She developed retroperitonitis and retroperitoneal emphysema due to iatrogenic duodenal perforation. We inserted a nasogastric tube into her stomach in order to decompress the gastrointestinal tract, and cefoperazone and proton pump inhibitors were administered intravenously. Her symptoms of retroperitonitis were then reduced. However, she developed enteritis suspected due to MRSA infection complicated by acute respiratory distress syndrome, acute renal failure and shock. We administered vancomycin via nasogastric tube, but her symptoms did not improve, so we added shojokito. She relieved her bowels after the administration of shojokito, and an antipyretic tendency was observed. Her breathing status recovered to normal, her blood pressure was stable, and her general condition gradually improved.
In recent years, we have not had many opportunities to perform Kampo treatment for severe infection cases needing hospitalization, but Kampo application has the potential to enhance the efficacy of infection treatments. Thus we advocate the active carrying out of Kampo treatment for patients with intestinal infection.

We report two cases of inchinkoto treatment for obstructive jaundice via autoimmune pancreatitis (AIP). Case 1 : A 38-year-old male. After completion of treatment for Mikulicz disease, obstructive jaundice developed. A diagnosis of AIP was based on a high IgG 4 blood level and image views. T-Bil stayed above 20 mg/dl and there was no improvement by oral administration of prednisolone (PSL), ursodeoxycholic acid, or bilirubin adsorption therapy. Upon inchinkoto administration, T-Bil promptly fell to 3 mg/dL. Case 2 : A 77-year-old male. He suffered from itching and constipation, and blood data showed a pattern of obstructive jaundice. Image views suggested AIP, but a duodenal papillary biopsy could not provide a definitive diagnosis. Inchinkoto was administered, and the itching and constipation had mostly disappeared within 1 week. However, these symptoms recurred after one month. A definitive diagnosis of AIP was then reached based on a pancreas biopsy, and a PSL regimen was initiated. From these two cases, we consider that inchinkoto is useful for improving the symptoms of obstructive jaundice induced by AIP.
