Objective: In this study, we evaluated distinctive types of physical predisposition in patients with common side effects.
Method: We selected 500 and 1,200 individuals with and without a previous diagnosis of side effects, respectively, through web-based research. Then, we conducted a decision tree analysis for investigating the status of 100 types of physical predisposition in these individuals.
Results and Conclusion: The individuals who had suffered from hepatic disorder and answered “relevant” for “predisposition to swelling” (likelihood ratio of a positive result [LR+] 2.17; p=0.004) and “very relevant” for “predisposition to skin dryness” (LR+ 3.52; p<0.001) enhanced the probability of extracting individuals who developed side effects. The individuals who had suffered from skin disorder and answered “relevant” for “predisposition to eczema and inflammation” and “not relevant” for “predisposition to higher temperature” had an LR+ of 2.22 (p<0.001). The individuals with “predisposition to worsening of physical condition on a rainy or high-humidity day” are more likely to develop side effects with the use of antibiotics and NSAIDs, compared to those without this predisposition (antibiotics: LR+ 2.33; NSAIDs: LR+ 2.51). The results of this study indicate that we can identify patients with a high risk of side effects through an interview on predisposition.

Objective : There are two types of studies on the relationship between adverse events and genetic background and the relationship between constitution and genetic background. To investigate the relationship between adverse events and constitution retrospectively, we first reviewed the appearance of the constitution responsible for the adverse events in the relevant sources of information.
Methods : Fifty two pharmaceutical interview sheets, 150 case reports and two manuals; “jyudaina fukusayou kaihi notameno fukuyaku sidou jyouhousyu”, “jyutoku fukusayou sikanbetu manual” were selected for review.
Results : Fourteen items about the constitution were found in the pharmaceutical interview sheets. No items about the constitution were found in the case reports and manuals.
Conclusion : Rules for the preparation of pharmaceutical interview sheets and case reports to use the constitution information is necessary for retrospective analysis of this issue.

A 72-year-old woman underwent thoracic endovascular aortic repair (TEVAR) for an aortic arch aneurysm at a previous hospital. During follow-up, although the aneurysm was found to have become bigger, no further treatments were given, except for conservative follow-up. The patient sought a second opinion and thus visited our hospital. Enhanced computed tomography (CT) revealed a type I endoleak that required repair. Total arch replacement with removal of the partial stent-graft system was performed under deep hypothermic circulatory arrest. The patient made a steady progress postoperatively and was discharged without any complications. Endovascular repair is minimally invasive and frequently used in various medical facilities but carries a considerably high risk of reintervention. Treatment strategies for aortic aneurysm, including open surgery, should be carefully chosen.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

Introduction: Although stop-and-go method is recommended for the introduction of methadone by the Japanese guidelines, it may temporarily result in inadequate pain control and/or serious side effects. We report our experience that alleviation of symptoms was achieved by introducing low-dose methadone at an early stage on top of preceding opioids for a patient with refractory cancer pain. Case: Tapentadol and an analgesic adjuvant were given to a 70-year-old man to treat the patient’s old anal pain due to recurrence of rectal cancer at the rectal anastomosis. However, since the pain was poorly controlled, methadone 5 mg was given adjunctively once daily. After methadone medication, remarkable alleviation of pain and improvement in QOL were observed. Discussion: To achieve a safe pain management, adding a small amount of methadone at an early stage, as in this case, may possibly considered.
