Between August 2008 and June 2012, 17 TEVAR procedures for thoracic aortic aneurysms (TAA) requiring Z2 coverage were performed at our institution. Patient age ranged from 46 to 82 years old (mean 69.4), 16 were male. Criteria for LSA revascularization at our institution are defined as either : 1) dominant left vertebral artery (VA), 2) absent or diminutive or occluded right VA, 3) no communication of bilateral VA, 4) bilateral carotid artery disease, 5) patent LIMA-coronary bypass, 6) if a long length of the thoracic aorta is covered. Devices utilized were Gore TAG (n=12) and TX2 (n=5). Deployment of the stent-graft (SG) was successful in 17 cases (100%) and complete thrombosis of the aneurysm or complete entry closure was achieved in 16 cases (94.1%). Axillo-axillar cross over bypass (Ax-Ax B) was performed in 5 cases (29.4%). There was no instance of cerebrospinal ischemia or hospital death and the mean follow-up was 22.9 month (range 5 to 46). One case was converted to open surgery due to secondary type 1 endoleak. There was no instance of Ax-Ax B graft occlusion or aneurysmal rupture. The initial and mid-term results of TEVAR requiring Z2 coverage were satisfactory, and we believe that our criteria for LSA revascularization played an important role in providing the satisfactory results.

We reporte the initial results of open stent-grafting (OSG) applied with a Matsui-Kitamura (MK) stent in the treatment of thoracic aortic aneurysm (TAA). From August 2005 to March 2011, OSG for TAA was applied in 35 cases (male/female, 29/6, 58∼86 years old, mean age 71). During deep hypothermic circulatory arrest with antegrade selective cerebral perfusion, the stent graft was delivered through the transected proximal aortic arch, followed by arch replacement with a 4-branched prosthesis. Concomitant procedures included 1 coronary artery bypass graft, 1 mitral valve replacement and 2 pacemaker implantations. Operative mortality within 30 days was 5.7% (respiratory failure in 1 and ischemic enteritis in 1). There was 1 in-hospital death due to brain stem infarction. Perioperative morbidity included 2 (5.7%) stroke, 5 (14.3%) spinal cord injuries (paraplegia in 1, paraparesis in 1 and transient paraparesis in 3) , and 1 (2.9%) temporary hemodialysis. Ten patients (28.6%) were intubated for more than 72 h. There was no complication with the graft-related incident. These initial results suggested the OSG method applied with a MK stent is a useful surgical procedure for the treatment of TAA.

Purpose: Hiccups are a symptom that often appear in lung cancer patients during medical treatment. Although various drugs and non-pharmacologic therapies are used to treat them, they often are not effective. We report 2 cases of successful treatment for refractory hiccups due to chemotherapy for lung cancer using pregabalin. Case report: Both patients had advanced squamous lung cancer. That in case 1 was treated using chemotherapy with carboplatin and paclitaxel, while the case 2 received nedaplatin and irinotecan. Hiccups occurred and became exacerbated during chemotherapy in both, and were considered to be induced by the anticancer drugs. Separate treatments with metoclopramide, chlorpromazine, and gabapentin did not have any effect, whereas immediate improvement was seen after taking pregabalin in both cases. Conclusion: Pregabalin, often used as an adjuvant analgesic, controls excessive neuronal excitement. In the present cases, effective relief of refractory hiccups was seen.

Objective: In this study, we investigated the occurrence of skin damage following the initiation of low-dose lamotrigine.Methods: We retrospectively analyzed the incidence of skin disorders within 8 weeks of the start of lamotrigine administration, prescribing for 3 years from July 2014 to June 2016.In addition, we also confirmed the onset time of skin disorders in the low- and normal-dose groups.Results: The incidence of skin damage was 7.7 and 24.6 % in the low- and normal-dose lamotrigine start groups, respectively. The onset of skin disorders was relatively early in the normal-dose lamotrigine start group.On the other hand, no tendency was found in the low-dose lamotrigine start group because the number of cases was small.Conclusion: The initiation of low-dose lamotrigine and extension of introduction period might reduce the onset of early skin damage.

Objective: The internet isflooded with drug information; however, some of it isinappropriate and thisinadequate information could expose the public to health hazards. Therefore, we conducted research on the idea of transmitting drug information to the public via the internet and the current state of the information currently provided by each academic society relevant to the field of Medical Informatics.Methods: A questionnaire was mailed to the website managers for the website of 129 specialist medical societies, all members of the Japanese Association of Medical Sciences. We conducted our research between October to November 2018. We investigated each website administrator’s opinion about offering drug information for consumers via the internet and what information each academic society is currently providing.Results: The effective response rate was 43.4% (56/129 groups). Most respondents thought that drug information overflowed in the current Internet society. Moreover, more than half of the respondents thought that the quality of drug information transmitted to the public wasinadequate. Currently, 30 of the academic groupssurveyed are providing information to the public. When providing information, they did not refer to the “Drug Guide for Patients” much. More than 80% of respondents said they would cooperate with linking to the information provided to the public. However, each academic society felt there would be many problems with doing so such as the need for a system to check the contents of the information provided and a system to perform maintenance.Conclusion: The results showed that the website administrators recognized that there is a need to improve the quality of and system for providing drug information to the public. We believe that an integrated information system can be constructed by aggregating the drug information held by each academic society. However, this cannot be realized without first solving many problems.

Objective: We have developed an automatic vigilance system (AVS) that automatically reports adverse drug reactions (ADR) based on laboratory finding abnormalities and symptom keywords in electronic medical records. In this study, we aimed to evaluate the impact of detecting ADR using AVS on medical treatment.Methods: In AVS, drugs and their ADR signals, which would be detected and reported by AVS to pharmacists, were defined. Pharmacists evaluated the severity of these signals to identify whether these signals should be discussed with the doctor, continued to be followed up, or ignored. We investigated detection of ADR at University of Fukui Hospital between April 2016 and March 2017 along with whether prescriptions were modified because of ADR and the contribution of AVS. Assuming that ADR had worsened without appropriate treatment, medical expenses needed for treating severe ADR were calculated.Results: In total, 325 signals were defined for 146 drugs. There were 9,103 ADR signals confirmed by pharmacists for 8,531 subjects. Of these, 12 and 164 signals were discussed with the doctor and continuously observed, respectively. The pharmacist's suggestions based on AVS led to prescription modifications in 10 cases, corresponding to a reduction of 2.56 million yen in medical expenses in the event that these cases become severe.Conclusion: AVS assisted prescription revisions because of ADR and is thought to contribute to the prevention of worsening of ADR and reduction of medical expenses.

Objective: In this study, we conducted a questionnaire survey of hospital pharmacists throughout Japan with the aim of identifying the most-requested in-hospital preparations and off-label use drugs, and exploring the possibility of commercializing them.Methods: The Commercialization Study Group of the Japanese Society of Hospital Pharmacists conducted a questionnaire survey on the Japanese Society of Hospital Pharmacists website targeting hospital pharmacists who are members of the Japanese Society of Hospital Pharmacists. The period of the survey was from February 1, 2019 until January 21, 2020. In the questionnaire, the respondents wrote specific product names (generic names), specifications, and dosage forms that they would like to see improved and made commercially available in a free-text format. In addition, respondents chose their reasons for wanting the product to be improved or made commercially available from a list.Results: A total of 1,627 drugs were requested to be made commercially available. After duplicates and insufficient descriptions were excluded, the total was 553. The drugs that were most frequently requested were Levothyroxine suppositories, followed by Mohs’ ointment and Ulinastatin vaginal suppositories.Discussion: This survey identified certain drugs that pharmacists want to be commercialized and the specific reasons why. In-hospital preparations not only benefit patients whose diseases are becoming more complex and difficult to treat with existing prescription drugs, but also enable pharmacists to demonstrate their abilities. We believe that the commercialization of these important in-hospital preparations and off-label drugs will help avoid various risks associated with dispensing them and enhance the pharmacy profession. For this reason, pharmaceutical drug companies should conduct further surveys on the actual use of and literature research on the efficacy and safety of the drugs that were ranked high on the questionnaire and start considering their commercialization.

Objective: We evaluated patients’ degree of understanding of the effects and adverse drug reactions of SGLT2 inhibitors.Methods: We targeted 26 patients who were administered SGLT2 inhibitors during hospitalizations between April 2017 and March 2018. The survey was conducted by interviewing the patients using a questionnaire.Results: In total, 14 patients (53. 8%) were able to explain the term “efficacy.” Although 6 patients (23. 1%) understood “dehydration,” there was little understanding of “urinary tract infection” (7.7%) and “rash/erythema” (2 and 0 patients, respectively). In addition, we confirmed the details of the descriptions of adverse reactions caused by SGLT2 inhibitors with pharmacists, and found that 13 patients (50.0%) clearly received an explanation of “dehydration,” only 3 patients received an explanation of “urinary tract infection” (11.5%), and none of them comprehended “rash/erythema.” Overall, the patients’ awareness of the adverse drug reactions of SGLT2 inhibitors was low.Conclusion: Unlike common drugs for diabetes, SGLT2 inhibitors have been attracting attention as protective agents of the heart and kidneys. Therefore, it is expected that prescriptions for SGLT2 will increase in the future. Pharmacists need to explain the effects and adverse drug reactions of SGLT2 inhibitors to the patients as well as make the patients understand the pharmacological mechanisms of action of SGLT2 inhibitors.

Objective: Two types of symbols have been established as industry standards in terms of two-dimensional (2D) symbols with prescription information: one for objects to be printed on prescriptions and the other for electronic versions of medication diaries. However, no studies have investigated the system for using 2D symbols in pharmacies and hospitals/clinics as well as the quality of the information actually stored in these 2D symbols. Therefore, we conducted a survey to clarify the current status and problems pertaining to prescription information sharing via 2D symbols.Methods: We distributed questionnaires to community pharmacies through the Fukui Pharmaceutical Association and asked them to cooperate with us during the survey. The list of items in the survey included the installation status of devices necessary for reading 2D symbols at each pharmacy, receipt computer in use, and status of the support issued by hospitals/clinics for reading 2D symbols. At the same time, we received 2D symbols created by community pharmacies and conducted reading tests to examine issues related to the collection of prescription information via 2D symbols at medical institutions.Results: The response rate for the survey was 21.8%. Among the 57 stores that responded to the survey, 26 (45.6%) answered that they could read prescription symbols, and 22 of them had actually used the system till date. In addition, 38 community pharmacies were able to provide the 2D symbols for medication diaries. Of the 30 provided symbols for medication diaries, 16 (53.3%) could be read as Japanese data by the barcode reader used.Conclusions: It has become clear that the 2D symbols with stored prescription information are not being completely utilized at present, as both community pharmacies and hospitals/clinics face several issues such as hardware maintenance, software updates, and time and effort required for the usage.
