Objective: In the previous study, the CYP database was constructed in order to relate drug-drug interactions to the CYP metabolic information of the package inserts. In this study, we evaluated the clinical usefulness of the CYP database by using the Pharmaceutical and Medical Devices Agency (PMDA) Drug Monitoring Information.
Methods: We examined the drugs in CYP isoform responsible for drug metabolism. The age, sex, suspect drugs and co-administered drugs were extracted from 6,236 cases of the PMDA database of drug monitoring from January till November of 2008.
Results: Twenty-three percent of all cases had co-administered drugs. Forty-five percent of these cases were metabolized both suspect and co-administered drugs by the same CYP isoform, and three fourths of these cases were able to be detected only by the CYP database. In addition, the administration of substrate medicines in combination with substrate medicines was the largest (57%), followed by cases of substrate medicines in combination with inhibitor medicines (28%). Seventy-seven percent of the suspect drugs that had a large number of reported cases of side effects were substrate medicines, and the frequency of co-administration with substrate medicines was very high.
Conclusion: These data suggest that the CYP database, being used together with package inserts, might be a clinically useful tool to avoid adverse events caused by drug-drug interactions.

OBJECTIVE: Galvanic vestibular stimulation (GVS) activates the vestibular afferents, and these changes in vestibular input exert a strong influence on the subject's posture or standing balance. In patients with Parkinson's disease (PD), vestibular dysfunction might contribute to postural instability and gait disorders. METHODS: Current intensity was increased to 0.7 mA, and the current was applied to the patients for 20 minutes. To perform a sham stimulation, the current intensity was increased as described and then decreased to 0 mA over the course of 10 seconds. The patient's status was recorded continuously for 20 minutes with the patient in the supine position. RESULTS: Three out of 5 patients diagnosed with PD with postural instability and/or abnormal axial posture showed a reduction in postural instability after GVS. The score for item 12 of the revised Unified Parkinson's Disease Rating Scale part 3 was decreased in these patients. CONCLUSIONS: The mechanism of postural instability is complex and not completely understood. In 2 out of the 5 patients, postural instability was not changed in response to GVS. Nonetheless, the GVS-induced change in postural instability for 3 patients in our study suggests that GVS might be a therapeutic option for postural instability.

Kampo medicine has been used for patients with pneumophagia to improve deficiency and stagnation of qi. Here, we report a case in which symptoms were alleviated by treating spleen yang deficiency and liver qi stagnation as the main pathogenesis. The patient was a 75-year-old woman. She was diagnosed with atrophic gastritis after a close examination of her gastric discomfort. She took antacids and proton pump inhibitors, but the condition did not improve. Her abdominal distension and belching also appeared and worsened, so she requested Kampo treatment. Since she had interior cold with qi stagnation, we prescribed tokito that is able not only to warm interior cold but also to adjust qi sufficiently. The pathology of pneumophagia is generally considered to be stagnation of qi mainly and concomitant with deficiency of qi. However, for those having interior cold like this case, a medicine that can firmly perform warm supplementation is necessary, and tokito is considered to be a candidate for the condition. Strangled pain is mentioned as the main targeted symptom of tokito, and it is often administered for abdominal or chest pain. Although, in this case, abdominal pain might have occurred if the condition had worsened further, it is important to utilize tokito in the case of qi stagnation and yang deficiency regardless whether patients have pain or not.

Background/Aims:
Inflammatory bowel disease (IBD) is a chronic inflammation of the gastrointestinal tract. Some patients with this condition have been reported to present with immunoglobulin A nephropathy (IgAN), a renal complication that can cause end-stage renal failure, but the frequency of this comorbidity has not been described. Thus, the aim of this study was to investigate the frequency of IgAN in patients with IBD.
Methods:
This study included 620 patients with IBD (338 with ulcerative colitis [UC] and 282 with Crohn’s disease [CD]) from the Hiroshima University Hospital outpatient department. IgAN cases were identified from medical interviews, blood examinations (serum immunoglobulin A), and urinalyses (occult blood, proteinuria). Definitive IgAN cases were diagnosed by renal biopsies, while those detected through the clinical course and test results, but not clinically recommended for renal biopsy, were defined as suspected IgAN.
Results:
We analyzed 427 cases meeting the inclusion criteria (220 with UC and 207 with CD). The incidence of IgAN across all patients with IBD was 3.0%. The frequency of IgAN was significantly higher in patients with CD (11/207, 5.3%) than in those with UC (2/220, 0.9%) (P< 0.01). Moreover, a significant correlation was found between CD patients with ileostomy or colostomy and a diagnosis of IgAN.
Conclusions
Patients with IBD present a high incidence of IgAN, especially those with CD who have undergone ileostomy or colostomy.

The purpose of this study is to considerate the prediction formula for marathon time based on 20-m shuttle run test and training indexes in recreational runners. 100 male and 111 female recreational runners who have experienced one or more marathon races were measured. Each participant was measured with regard to physical characteristics, 20-m shuttle run test, and answered questionnaires about his/her training (monthly running distance, frequency of training, and years of experience of running training). Moreover, participants self-reported their best marathon time. Additionally, to examine the validity of the prediction formula, 14 male and 13 female recreational runners were measured using the 20-m shuttle run test and they answered the questionnaires about his/her training. The marathon time was significantly correlated with the participant’s BMI, the times of 20-m shuttle run test, the monthly running distance, the frequency of training and the years of experience of running training for both male and female runners. Subsequently, multiple regression analysis generated the prediction model for marathon time by the measurement items. Furthermore, in the examination of the validity of the prediction formula, predicted marathon time was significantly highly correlated with measured marathon time. This study suggested that the marathon time can be predicted by the 20-m shuttle run test, the monthly running distance, and the years of experience of running training and the predicted marathon time may be useful for the marathon race and training in recreational runners.

Purpose:
Patients with head and neck cancer (HNC) who undergo dental procedures during radiotherapy (RT) face an increased risk of developing osteoradionecrosis (ORN). Accordingly, new tools must be developed to extract critical information regarding the dose delivered to the teeth and mandible. This article proposes a novel approach for visualizing 3-dimensional planned dose distributions on panoramic reconstruction computed tomography (pCT) images.
Materials and Methods:
Four patients with HNC who underwent volumetric modulated arc therapy were included. One patient experienced ORN and required the extraction of teeth after RT. In the study approach, the dental arch curve (DAC) was defined using an open-source platform. Subsequently, pCT images and dose distributions were generated based on the new coordinate system. All teeth and mandibles were delineated on both the original CT and pCT images. To evaluate the consistency of dose metrics, the Mann-Whitney U test and Student t-test were employed.
Results:
A total of 61 teeth and 4 mandibles were evaluated. The correlation coefficient between the 2 methods was 0.999, and no statistically significant difference was observed (P>0.05). This method facilitated a straightforward and intuitive understanding of the delivered dose. In 1 patient, ORN corresponded to the region of the root and the gum receiving a high dosage (approximately 70 Gy).
Conclusion
The proposed method particularly benefits dentists involved in the management of patients with HNC. It enables the visualization of a 3-dimensional dose distribution in the teeth and mandible on pCT, enhancing the understanding of the dose delivered during RT.

Purpose: The purpose of this study is to evaluate hangeshashinto rinse for oral discomfort in terminally-ill cancer patients and to compare the effectiveness of hangeshashinto rinse with or without honey rinse. Methods: Patients with oral discomfort were randomized to receive either hangeshashinto rinse or hangeshashinto with honey rinse as first-line treatment. Patients performed oral rinse three to five times a day for 2 weeks. Further, oral wetness, halitosis, oral mucositis, mouth discomfort, compliance of rinse were then evaluated before and after the intervention. Results: 144 patients were enrolled during this period and 22 patients completed the study (hangeshashinto 13 / hangeshashinto with honey 9). After the intervention, oral wetness was improved, and end-tidal concentration of hydrogen sulfide was decreased in both cases. Although there was no statistically significant difference, oral discomfort by subjective and objective evaluations, also and symptom of oral mucositis were improved. Other volatile sulfur compounds decreased. Frequency of rinsing between groups receiving hangeshashinto or hangeshashinto with honey did not differ, however, the acceptability was slightly better in the honey combination group. Conclusion: Both hangeshashinto rinse and hangeshashinto with honey rinse reduced end-tidal concentration of hydrogen sulfide and improved oral wetness. Oral rinse by hangeshashinto or hangeshashinto with honey may be effective for oral discomfort in terminally-ill cancer patients.
