Exploratory study of cold hypersensitivity in Japanese women: genetic associations and somatic symptom burden.

Temperature perception is essential for humans to discern the environment and maintain homeostasis. However, some individuals experience cold hypersensitivity, characterized by a subjective feeling of coldness despite ambient environmental temperatures being normal, the underlying mechanisms of which are unknown. In this study, we aimed to investigate the relationship between subjective cold symptoms and somatic burden or single nucleotide polymorphisms to understand the causes of cold hypersensitivity. We conducted an online questionnaire survey [comprising 30 questions, including past medical history, subjective symptoms of cold hypersensitivity, and the Somatic Symptom Scale-8 (SSS-8)]. Respondents were 1200 Japanese adult female volunteers (age: 20-59 years), recruited between April 21 and May 25, 2022, who were customers of MYCODE, a personal genome service in Japan. Among the 1111 participants, 599 (54%) reported cold hypersensitivity. Higher cold hypersensitivity severity was positively associated with the SSS-8 scores. Additionally, a genome-wide association study for cold hypersensitivity was conducted using array-based genomic data obtained from genetic testing. We identified 11 lead variants showing suggestive associations (P < 1 × 10-5) with cold hypersensitivity, some of which showed a reasonable change in expression in specific tissues in the Genotype-Tissue Expression database. The study findings shed light on the underlying causes of cold hypersensitivity.

Patient prognosis and prediction model for taking Kampo formulas in dysmenorrhea: An observational study.

Two representative Kampo formulas, keishibukuryogan and tokishakuyakusan, are frequently prescribed for patients with dysmenorrhea. We previously constructed a model that could predict which of these 2 formulas was most suitable, which is based on 4 subjective symptoms and 3 objective signs. To evaluate the prognosis of patients with dysmenorrhea using the established prediction model and assess the treatment outcomes between those treated in accordance with the prediction model and those who received various other treatments. In this retrospective, observational study, we included patients with menstrual pain who visited the Kampo Clinic at the Keio University Hospital for the first time between October 2014 and December 2020. These patients were monitored over a 90-day follow-up period. Participants were categorized into 2 groups: model-accordance and various-options. The progression of visual analogue scale (VAS) values was evaluated by determining the slopes from regression analysis between these 2 groups, with changes corroborated by the medical records. The study comprised 57 patients: 37 in the model-accordance group and 20 in the various-options group. Notably, the various-options group reported a significantly higher number of subjective symptoms (P = .03). The VAS value showed a decline, as indicated by the negative slope value of the regression line, across both groups - irrespective of their classification. There were no significant differences in the occurrence of adverse events between the 2 groups. The prognosis of patients with dysmenorrhea and the incidence of adverse events remained consistent, regardless of whether the treatment approach was in accordance with the prediction model or varied. Further studies are warranted to assess the prognosis when Kampo formulas are chosen based on the prediction model in the various-options population.

Development of a novel drug information provision system for Kampo medicine using natural language processing technology.

BACKGROUND: Kampo medicine is widely used in Japan; however, most physicians and pharmacists have insufficient knowledge and experience in it. Although a chatbot-style system using machine learning and natural language processing has been used in some clinical settings and proven useful, the system developed specifically for the Japanese language using this method has not been validated by research. The purpose of this study is to develop a novel drug information provision system for Kampo medicines using a natural language classifier® (NLC®) based on IBM Watson. METHODS: The target Kampo formulas were 33 formulas listed in the 17th revision of the Japanese Pharmacopoeia. The information included in the system comes from the package inserts of Kampo medicines, Manuals for Management of Individual Serious Adverse Drug Reactions, and data on off-label usage. The system developed in this study classifies questions about the drug information of Kampo formulas input by natural language into preset questions and outputs preset answers for the questions. The system uses morphological analysis, synonym conversion by thesaurus, and NLC®. We fine-tuned the information registered into NLC® and increased the thesaurus. To validate the system, 900 validation questions were provided by six pharmacists who were classified into high or low levels of knowledge and experience of Kampo medicines and three pharmacy students. RESULTS: The precision, recall, and F-measure of the system performance were 0.986, 0.915, and 0.949, respectively. The results were stable even with differences in the amount of expertise of the question authors. CONCLUSIONS: We developed a system using natural language classification that can give appropriate answers to most of the validation questions.

Exploring Standardized Scales and Serum Biomarkers to Evaluate Changes in Pruritus due to Eczema after Japanese Kampo Treatment: A Prospective Case Series.

BACKGROUND: We aimed to explore standardized scales and serum biomarkers for tracking changes in the symptoms and severity of pruritus due to eczema in patients treated with Kampo formulas. PATIENTS AND METHODS: This prospective, single-arm, pre-post comparison case series recruited patients with pruritus mostly due to eczema who consulted the Kampo Clinic at the Keio University Hospital from June 2019 to March 2020. The participants were prescribed a personalized Kampo formula for 12 weeks. Patient profiles and symptoms were assessed every 4 weeks using the visual analog scale (VAS), patient-oriented eczema measure (POEM) scale, 5-D itch scale (5D), Skindex-16, and eczema area and severity index (EASI). Blood biomarkers and intestinal permeability indicators were measured at the first consultation and 12 weeks later. RESULTS: Pruritus and eczema severity improved significantly over time. The VAS, POEM, 5D, and Skindex-16 scores were well-correlated. The serum interleukin-31 levels decreased significantly after a 12-week intervention. Changes in the interleukin-31 level correlated with the diamine oxidase level at week 0, suggesting the involvement of the Th2 immune system and intestinal permeability in the mechanism of Kampo formulas. CONCLUSION: The evaluated scales are suitable for evaluating subjective symptoms and eczema severity after Kampo treatment; further studies are required to verify the study findings.

Climacteric symptoms in postoperative patients among endometrial cancer, cervical cancer, and ovarian cancer: a cross-sectional study.

PURPOSE: To date, no studies have assessed climacteric symptoms after hystero-adnexectomy for endometrial, cervical, or ovarian cancer. Thus, this study aimed to compare climacteric symptoms among patients who underwent surgery for these three cancer types. METHODS: In this cross-sectional study, we interviewed patients who were registered at a menopausal outpatient clinic between January 1999 and July 2016 after undergoing total hysterectomy, intrapelvic only or intrapelvic plus para-aortic lymph node dissection, and bilateral adnexectomy performed via laparotomy as a cancer treatment. Climacteric symptoms were assessed using a patient-reported questionnaire covering core domains with five symptoms only at the initial consultation. Each symptom was graded from 0 (no symptoms) to 3 (severe symptoms). We evaluated the frequency of symptom severity according to the time elapsed since surgery and the cancer type. RESULTS: The numbers of patients with endometrial, ovarian, and cervical cancer were 328, 90, and 107, respectively. Overall, climacteric symptoms were more severe in patients with cervical cancer than in those with endometrial or ovarian cancer; symptom severity decreased with increasing time since surgery. However, symptom severity did not decrease significantly over time in patients with cervical cancer even after > 5 years had elapsed since surgery. CONCLUSION: The climacteric symptoms were less severe in patients with endometrial or ovarian cancer with longer time elapsed since surgery but not in those with cervical cancer. Patients with cervical cancer may require more prompt interventions, including symptomatic treatment and longer follow-up period, than those with endometrial or ovarian cancer.

A prediction model of qi stagnation: A prospective observational study referring to two existing models.

OBJECTIVE: To establish a prediction model of qi stagnation referring to two existing models. DESIGN: Prospective observational study. SETTING: We recruited patients who visited the Kampo Clinic at Keio University from February 2011 to March 2013. METHODS: We constructed a random forest algorithm with 202 items as independent variables to predict qi stagnation patterns using full agreement data of the physicians' diagnosis and the result of two existing scores as a reference standard. To compare the new model with the two existing models, we calculated the discriminant ratio (prediction accuracy), precision, sensitivity (recall), specificity, and F-measure of these models. RESULTS: The number of eligible participants was 1,194, and 29.1% of them were diagnosed with qi stagnation by Kampo physicians. The discriminant ratio, precision, sensitivity, specificity, and F-measure in our new model were 0.960, 0.672, 0.911, 0.964, and 0.774, respectively. Our new model had a significantly higher discriminant ratio than the two existing models. CONCLUSIONS: We constructed a better qi stagnation prediction model than the previously established ones. Our results can be utilized to reach an international agreement on qi stagnation pattern diagnosis in traditional East Asian medicine.

Oral Astragalus Root Supplementation for Mild to Moderate Chronic Kidney Disease: A Self-Controlled Case-Series.

In this self-controlled case series, we aimed to investigate the variation in estimated glomerular filtration rate (eGFR) after taking astragalus-containing preparations in patients with mild to moderate chronic kidney disease (CKD) by retrospectively reviewing their charts in our clinic. We set the inclusion criteria as first-visit patients aged 20 years or older presenting to our clinic between 1 October 2014, and 31 June 2019, and who were prescribed astragalus-containing herbal preparations for any reason. We calculated the mean eGFR from the readings taken 6 months before (pre) and after (post) the intake of astragalus-containing preparations for each participant. Among the 37 patients included in our final analysis, we found a statistically significant improvement in the eGFR after prescribing astragalus-containing preparations (pre, 66 ± 12 ml/min/1.73 m2 vs. post, 70 ± 14 ml/min/1.73 m2; p < 0.001 by paired t-test). Our results were consistent regardless of age, sex, CKD stage of the participants (G2 or G3), daily dosage of astragalus root, or duration of astragalus-containing preparations. No severe adverse reactions were recorded in the charts of the study participants. Our results suggest that there is eGFR improvement after taking astragalus-containing preparations in mild to moderate CKD cases as reported previously. The findings should be considered with caution due to major limitations such as small sample size without optimum control, short follow-up period, and incomplete data. Further adequately powered and designed studies are needed to confirm the efficacy and safety of the long-term use of astragalus root in patients with mild to moderate CKD.

Inter-Rater Reliability of Kampo Diagnosis for Chronic Diseases.

This single-center observational study aimed to assess the inter-rater reliability (IRR) of Kampo medicine pattern diagnosis, which is modularized into three modules for chronic diseases, using 64 participants' information documents. The linearly weighted percentage of agreement and Gwet's agreement coefficient (AC) 2 for the deficiency-excess module, among three specialists, were 85.9% and 0.708, respectively. The unweighted percentage of agreement and Gwet's AC1 were 64.6% and 0.542 for the cold-heat, and 35.9% and 0.254 for the qi-blood-fluid modules, respectively. Our findings suggest that our modularization method may improve the IRR of Kampo medicine pattern diagnosis.

Relationship Between Conventional Medicine Chapters in ICD-10 and Kampo Pattern Diagnosis: A Cross-Sectional Study.

Objectives: The newest revision to the International Classification of Diseases, the 11th edition (ICD-11) includes disease classifications from East Asian medicine, including traditional Japanese medicine (Kampo medicine). These disease classifications allow for comparisons between disease classifications from conventional medicine and Kampo medicine. Design/Location/Subjects/Interventions: This is an exploratory, cross-sectional study exploring the relationship between conventional medicine diagnoses and Kampo medicine diagnoses at a large Kampo clinic in Japan. Patients were seen from October 1st, 2014 to June 30th, 2019 and were 20 years of age or older. Outcome measures: Patients presented with one or more conventional medicine ICD-10 codes into the clinic and were given one descriptor from the ICD-11 within the heat-cold module, excess-deficiency module, and an optional body constituents module. The distribution of these Kampo medicine codes was examined in relation to conventional medicine chapters. Results: 1,209 patients were included in our final analysis. Patient number, ages, sex ratio, and BMI varied within conventional medicine ICD-10 chapters and Kampo medicine descriptor codes. Certain conventional medicine chapters are related to specific Kampo medicine descriptor codes, such as chapter IV (endocrine, nutritional, and metabolic diseases) with excess, heat, and kidney qi deficiency. Conclusion: The advent of the ICD-11 allows for systematic, standardized comparisons between Kampo medicine, and contemporary medicine. In this exploratory study, our findings support the independence of Kampo medicine pattern descriptors with ICD-10 conventional medicine chapters. Code overrepresentations in relation to conventional medicine diseases and by age and sex should be an area of future investigation to best understand how to synergize and improve patient care.

Discrimination of prediction models between cold-heat and deficiency-excess patterns.

OBJECTIVE: The purpose of this study was to extract important patient questionnaire items by creating random forest models for predicting pattern diagnosis considering an interaction between deficiency-excess and cold-heat patterns. DESIGN: A multi-centre prospective observational study. SETTING: Participants visiting six Kampo speciality clinics in Japan from 2012 to 2015. MAIN OUTCOME MEASURE: Deficiency-excess pattern diagnosis made by board-certified Kampo experts. METHODS: We used 153 items as independent variables including, age, sex, body mass index, systolic and diastolic blood pressures, and 148 subjective symptoms recorded through a questionnaire. We sampled training data with an equal number of the different patterns from a 2 × 2 factorial combination of deficiency-excess and cold-heat patterns. We constructed the prediction models of deficiency-excess and cold-heat patterns using the random forest algorithm, extracted the top 10 essential items, and calculated the discriminant ratio using this prediction model. RESULTS: BMI and blood pressure, and subjective symptoms of cold or heat sensations were the most important items in the prediction models of deficiency-excess pattern and of cold-heat patterns, respectively. The discriminant ratio was not inferior compared with the result ignoring the interaction between the diagnoses. CONCLUSIONS: We revised deficiency-excess and cold-heat pattern prediction models, based on balanced training sample data obtained from six Kampo speciality clinics in Japan. The revised important items for diagnosing a deficiency-excess pattern and cold-heat pattern were compatible with the definition in the 11th version of international classification of diseases.

Differences in demographics and complementary and alternative medicine use between patients attending integrative kampo versus biomedical clinics in Japan.

OBJECTIVES: Growing interest in integrative medicine motivates examination of who seeks integrative care, and why. By examining differences in demographics and complementary and alternative medicine (CAM) use between patients recruited from Japanese Kampo (traditional herbal medicine) versus biomedical clinics, this study aimed to identify whether integrative medicine options might attract different patients. DESIGN AND SETTING: In this cross-sectional, observational study we administered the International Complementary and Alternative Medicine-Questionnaire (I-CAM-Q) to 209 patients recruited from four hospital clinics. Demographics, use of different types of CAM (self-help CAM, CAM practitioners, CAM products), and motivations were compared between Kampo and Non-Kampo patients and by gender. Factors influencing attendance at the Kampo clinic and CAM use were identified using logistic regression. RESULTS: While some demographic characteristics, CAM provider and total CAM use differed between Kampo and non-Kampo patients, self-help CAM use did not. Motivations (for acute, long-term, health maintenance, or other reasons) differed between Kampo and non-Kampo clinic patients for going to non-Kampo physicians (P = 0.02) and Kampo physicians (P = 0.1). Logistic regression results for 'any CAM' use showed odds ratio of 0.32 (95%CI 0.15-0.67) for self-rated health, and 1.60 (95%CI 1.10-2.32) for Macarthur subjective social status scale. Attendance at the Kampo clinic showed odds ratios of 1.50 (95%CI 1.11-2.02) for education and 0.56 (95%CI 0.39-0.80) for employment status. CONCLUSIONS: Better understanding of factors such as motivation, self-rated health, and socioeconomic conditions that influence patients' CAM use and integrative clinic attendance may enable more effective targeting of populations and integration of CAM into biomedical settings.

Prediction of deficiency-excess pattern in Japanese Kampo medicine: Multi-centre data collection.

OBJECTIVE: The purpose of the present study was to compare important patient questionnaire items by creating a random forest model for predicting deficiency-excess pattern diagnosis in six Kampo specialty clinics. DESIGN: A multi-centre prospective observational study. SETTING: Participants who visited six Kampo specialty clinics in Japan from 2012 to 2015. MAIN OUTCOME MEASURE: Deficiency-excess pattern diagnosis made by board-certified Kampo experts. METHODS: To predict the deficiency-excess pattern diagnosis by Kampo experts, we used 153 items as independent variables, namely, age, sex, body mass index, systolic and diastolic blood pressures, and 148 subjective symptoms recorded through a questionnaire. We extracted the 30 most important items in each clinic's random forest model and selected items that were common among the clinics. We integrated participating clinics' data to construct a prediction model in the same manner. We calculated the discriminant ratio using this prediction model for the total six clinics' data and each clinic's independent data. RESULTS: Fifteen items were commonly listed in top 30 items in each random forest model. The discriminant ratio of the total six clinics' data was 82.3%; moreover, with the exception of one clinic, the independent discriminant ratio of each clinic was approximately 80% each. CONCLUSIONS: We identified common important items in diagnosing a deficiency-excess pattern among six Japanese Kampo clinics. We constructed the integrated prediction model of deficiency-excess pattern.

The use of maoto (Ma-Huang-Tang), a traditional Japanese Kampo medicine, to alleviate flu symptoms: a systematic review and meta-analysis.

BACKGROUND: Influenza is a common viral infection worldwide. Maoto (ma-huang-tang) was developed in ancient China and is used to alleviate flu symptoms. Currently, no meta-analyses have evaluated the efficacy and safety of maoto for alleviating flu symptoms. METHODS: In the present study, we searched MEDLINE/PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, a Japanese database (Ichushi), two Chinese databases (China National Knowledge Infrastructure and VIP), and two Korean databases (Korean Medical database and Korean Association of Medical Journal Editors) for studies published in or before October 2017. Clinical studies that compared maoto plus neuraminidase inhibitors (NAIs) vs. NAIs alone, or maoto alone vs. NAIs alone, were included in the present analysis. The primary outcome measure (efficacy) was the length of time from the start of medication to resolution of influenza symptoms (fever, headache, malaise, myalgia, and chills) and virus isolation. The secondary outcome measures (safety) were as follows: (1) side effects and adverse reactions, such as nausea, abnormal behaviour, or discontinuation of symptomatic treatment; (2) morbidity (complications caused by influenza infection) or mortality; and (3) hospitalisation for any reason. RESULTS: Twelve relevant studies were identified, including two randomised controlled trials (RCTs, N = 60) and ten non-randomised studies (NRSs, N = 1110). We found that maoto plus NAIs was superior to NAIs alone in terms of the duration of fever in one RCT (P < 0.05, median difference = - 6 h) and four NRSs (P = 0.003, weighted mean difference = - 5.34 h). The duration of symptoms or virus isolation did not differ between maoto and NAIs. No severe side effects or adverse reactions were reported related to maoto or NAIs. CONCLUSIONS: Although we could not reach a definitive conclusion because of the small sample sizes and high risk of bias in the analysed studies, maoto may lower the duration of fever when it is used alone or in combination with NAIs and may be a well-tolerated treatment. More RCTs are needed to determine the efficacy and safety of maoto.

Safety of Daiobotampito in the Treatment of Acute Diverticulitis of the Colon: A Single-Center, Open-Label, Prospective Trial.

PURPOSE: The purpose of this study was to investigate the safety of daiobotampito in the treatment of acute diverticulitis of the colon. METHODS: We conducted a single-center, open-label, prospective study. Ten patients who suffered from diverticulitis of the colon were recruited. The patients were treated with fasting, antibacterial agents, and daiobotampito extract for 10 days in or out of hospital. The patients individually recorded their body temperature, grade of abdominal pain, number of times that analgesics were used, and number of stools daily. We checked whether the patients had adverse reactions such as abdominal pain or diarrhea. RESULTS: No patients experienced serious adverse reactions. One patient had moderate abdominal pain and diarrhea soon after daiobotampito intake. This patient discontinued daiobotampito on day 4, and the pain and diarrhea quickly resolved. The abdominal pain of this patient was worse 6 days before treatment, and the pain was almost relieved with initial daiobotampito treatment. CONCLUSIONS: Daiobotampito is a safe treatment option for early stage, acute diverticulitis.

Goshajinkigan for Low Back Pain: An Observational Study.

OBJECTIVES: Low back pain (LBP) is a chronic condition. Although Western treatments are available, Kampo (traditional Japanese) medicine is widely prescribed and covered by health insurance in Japan. Goshajinkigan (GJG), a Kampo formula, is commonly used to treat LBP. However, cases we have occasionally been encountered in which GJG did not show the expected effects. Hence, the purpose of this retrospective study was to investigate patient factors important in developing the effects of GJG. METHODS: This was a retrospective observational study based at the Center for Kampo Medicine, Keio University Hospital. Data were retrieved from the medical records of 28 patients who visited our hospital between May 2008 and March 2013 and who received GJG for LBP. The patients were divided into responders and non-responders based on whether their LBP improved post treatment. The groups were compared with respect to daily GJG dose, incidence of spine disease, and side effects. RESULTS: Ten patients (responders) reported an improvement in LBP within 6 months. One patient experienced decreased appetite as a side effect. Nine patients reported no improvement (non-responders). The number of patients prescribed the usual daily dose of GJG (7.5 g) was significantly higher among responders than it was among non-responders (p = 0.023), and the number of patients with spine disease was significantly greater among non-responders than it was among responders (p = 0.020). The number of patients with spinal stenosis was significantly higher among non-responders than it was among responders (p = 0.011). Therefore, the usual daily dose of GJG provided significant relief of LBP, particularly in patients without any spine disease. CONCLUSIONS: Routine daily administration of GJG in patients without spine disease seems to lead to the effects of the product. However, further investigations using the above-mentioned parameters are needed to confirm these findings.

Predicting Japanese Kampo formulas by analyzing database of medical records: a preliminary observational study.

BACKGROUND: Approximately 90 % of physicians in Japan use Kampo medicine in daily practice. However, it is a challenge for physicians who do not specialize in Kampo medicine to select a proper Kampo formula out of the 148 officially approved formulas, as the decision relies on traditional measurements and traditional medicine pattern diagnoses. The present study tries to evaluate the feasibility of a decision support system for frequently used Kampo formulas. METHODS: Our study included 393 patients who visited the Kampo Clinic at Keio University Hospital for the first time between May 2008 and March 2013. We collected medical records through a browser-based questionnaire system and applied random forests to predict commonly prescribed Kampo formulas. RESULTS: The discriminant rate was the highest (87.0 %) when we tried to predict a Kampo formula from two candidates using age, sex, body mass index, subjective symptoms, and the two essential and predictable traditional medicine pattern diagnoses (excess-deficiency and heat-cold) as predictor variables. The discriminant rate decreased as the candidate Kampo formulas increased, with the greatest drop occurring between three (76.7 %) and four (47.5 %) candidates. Age, body mass index, and traditional medicine pattern diagnoses had higher importance according to the characteristics of each Kampo formula when we utilized the prediction model, which predicted a Kampo formula from among three candidates. CONCLUSIONS: These results suggest that our decision support system for non-specialist physicians works well in selecting appropriate Kampo formulas from among two or three candidates. Additional studies are required to integrate the present statistical analysis in clinical practice.

The Difference between the Two Representative Kampo Formulas for Treating Dysmenorrhea: An Observational Study.

In Kampo medicine, two different formulas are effective for treating dysmenorrhea-tokishakuyakusan and keishibukuryogan; however, the criteria by which specialists select the appropriate formula for each patient are not clear. We compared patients treated with tokishakuyakusan and those with keishibukuryogan and proposed a predictive model. The study included 168 primary and secondary dysmenorrhea patients who visited the Kampo Clinic at Keio University Hospital. We collected clinical data from 128 dysmenorrhea patients, compared the two patient groups and selected significantly different factors as potential predictors, and used logistic regression to establish a model. An external validation was performed using 40 dysmenorrhea patients. Lightheadedness, BMI < 18.5, and a weak abdomen were significantly more frequent in the tokishakuyakusan group; tendency to sweat, heat intolerance, leg numbness, a cold sensation in the lower back, a strong abdomen, and paraumbilical tenderness and resistance were more frequent in the keishibukuryogan group. The final model fitted the data well. Internally estimated accuracy was 81.2%, and a leave-one-out cross-validation estimate of accuracy was 80.5%. External validation accuracy was 85.0%. We proposed a model for predicting the use of two Kampo formulas for dysmenorrhea, which should be validated in prospective trials.

Post-gastrectomy Syndrome Successfully Treated With Kampo Medicine: A Case Report.

Cancer-related gastrectomy can cause post-gastrectomy syndrome, which includes weight loss, dumping syndrome, and reflux esophagitis and negatively affects the quality of life. Comprehensive and individualized patient management is required; however, there is a limit to Western medicine's ability to treat these symptoms. Kampo, a traditional Japanese medicine, adapts treatments to each individual's symptoms and constitution. We treated a 68-year-old male patient with post-gastrectomy syndrome using senpukukataishasekito, a Kampo medicine. He was diagnosed with Stage II-A gastric cancer at age 66 years and underwent a laparoscopic, pylorus-preserving gastrectomy followed by chemotherapy for 13 months. He visited our clinic for chemotherapy-related fatigue, postsurgical weight loss, and limb numbness. He was prescribed both hachimijiogan and hochuekkito. At the second visit, he complained of stomach discomfort, so we prescribed senpukukataishasekito. As his stomach function improved, his body weight increased and his fatigue decreased. We suggest that senpukukataishasekito may be an effective treatment for post-gastrectomy syndrome.

La gastrectomía relacionada con el cáncer puede provocar el síndrome de evacuación gástrica rápida, que incluye pérdida de peso, evacuación gástrica rápida y esofagitis por reflujo gastroesofágico, y afecta negativamente a la calidad de vida. Es necesario el tratamiento completo e individualizado del paciente; sin embargo, existe un límite en la capacidad de la medicina occidental para tratar estos síntomas. La Kampo, una medicina tradicional japonesa, adapta los tratamientos a los síntomas y constitución de cada individuo. Tratamos a un paciente de 68 años con síndrome de evacuación gástrica rápida usando senpukukataishasekito, una medicina Kampo. Se le diagnosticó un cáncer gástrico en estado II-A a la edad de 66 años y se sometió a una gastrectomía laparoscópica conservando el píloro, seguida de quimioterapia durante 13 meses. Visitó nuestra clínica por cansancio relacionado con la quimioterapia, pérdida de peso posterior a la operación e insensibilidad en las extremidades. Se le prescribieron tanto hachimijiogan como hochuekkito. En la segunda visita, se quejaba de molestias estomacales, así que le prescribimos senpukukataishasekito. A medida que mejoró el funcionamiento de su estómago, aumentó su peso corporal y disminuyó su cansancio. Sugerimos que senpukukataishasekito podría ser un tratamiento eficaz para el síndrome de evacuación gástrica rápida.

Polymorphisms of estrogen metabolism-related genes ESR1, UGT2B17, and UGT1A1 are not associated with osteoporosis in surgically menopausal Japanese women.

INTRODUCTION: Bilateral salpingo-oophorectomy (BSO) is a risk factor for osteoporosis. Previous studies have reported an association between genetic polymorphisms and the risk of developing osteoporosis. However, the relationship between osteoporosis and genetic polymorphisms in Japanese women treated with BSO is not well understood. To improve the quality of life for post-BSO patients, it is important to determine the genetic factors that influence their risk for osteoporosis. The aim of this study was to investigate the association between gene variations of estrogen metabolism-related genes and osteoporosis in surgically menopausal patients, which may improve their quality of life. MATERIAL AND METHODS: This study included 203 menopausal women treated with BSO because of gynecologic disorders. One hundred and twenty-six women with artificial (surgical) menopause, who had undergone BSO in the premenopausal period, were compared with 77 women with natural menopause, who had undergone BSO in the postmenopausal period. The women were tested for bone mineral density to diagnose osteoporosis. Polymorphisms of estrogen receptor 1 (ESR1) and UDP-glucuronosyl transferase (UGT) genes UGT2B17 and UGT1A1 were analyzed, and their association with bone mass and osteoporosis was statistically evaluated. RESULTS: No significant association was found between osteoporosis and polymorphisms in ESR1, UGT2B17, or UGT1A1 in both groups, suggesting that BSO might be a more significant physiological factor in influencing bone mass density compared to genetic variations. CONCLUSIONS: These results suggest that the ESR1, UGT2B17, and UGT1A1 polymorphisms are not genetic factors affecting osteoporosis in postmenopausal Japanese women.

Daisaikoto for menstrual pain: a lesson from a case with menstrual pain successfully treated with daisaikoto.

Menstrual pain is one of the common symptoms among women. It is estimated that 5-14% of women are sometimes absent from school or work because of pain. Usually gynecologists prescribe analgesics and/or low-dose oral contraceptives. However, such treatment is not always effective and sometimes causes an adverse effect, such as stomach pain or low body temperature. Kampo medicine is one of the choices for the menstrual pain in Japan. Tokishakuyakusan, kamishoyosan, or keishibukuryogan is commonly used for the treatment of menstrual pain. Here we report a case of menstrual pain successfully treated with daisaikoto which is not commonly used for such a case. Twenty-five-year-old woman suffered from severe menstrual pain and stress at company. She also had constipation and abdominal distension. We prescribed daisaikoto extract 7.5 g per day. Not only menstrual pain but also constipation and abdominal distension improved within 6 months. Here we propose that daisaikoto is one of the choices for the treatment of menstrual pain with mental stress.
