    Objective: In previously reported comparisons of aminoglycoside antimicrobials administered once daily versus multiple administration, toxicity was found to be equal or lower while efficiency remained high.  However, there are few reports on the clinical condition of targeted elderly persons.  The objective of this study was to evaluate the once-daily dosing regimen of 400 mg of AMK involving elderly pneumonia patients aged 75 years or older with regard to clinical evaluation including the efficacy and toxicity.
    Methods: A survey to clinically evaluate the efficacy and toxicity of 400 mg AMK administered once daily for 30 min at 24 h intervals was carried out.  One hundred twenty-seven patients with pneumonia and who were 75 years or older at Funabashi General Hospital were targeted, with the aim of an expected clinical effect of Cmax/MIC≥ 8-10.  Serum concentration monitoring was carried out after administration began.
    Results: There were 121 patients (95.3%) of controlled AMK concentration with a trough serum concentration of <10 μg/mL, which is a safe concentration range.  There were 6 patients (4.7%) where trough serum concentration in the toxic range >10 μg/mL, with an average at 15.1±5.0 μg/mL, and the average administration days were 7.5 ± 3.3 days.  Moreover, before/after AMK administration, there were 3 patients (2.4%) where CRE values increased more than a 150% over the previous values, and were evaluated as renal dysfunction.  Average trough serum concentration at that time was 3.6 ± 1.1 μg/mL, and average number of days of administration were 13 ± 1.4 days.  Patients of trough serum concentration in the toxic range >10 μg/mL were not included.  The average peak serum concentration calculated by Winter’s pharmacokinetic parameter and the 1-compartment model was 35.3 ± 8.0 μg/mL, and the average Cmax/MIC which correlates with the AMK effect was 9.9 ± 2.2.  The treatment was effective for 83 (65.4%) of the 127 patients.
    Conclusion: By once-daily administration of AMK 400 mg to aged persons 75 years or older, change in trough serum concentration into a safe range and Cmax/MIC≥ 8-10, the level at which clinical effectivity can be expected, could be achieved.  This administration method is shown to be useful in maintaining AMK in the target serum concentration range for aged persons.

    Objective: The revised Pharmaceutical Affairs Act that came into force in June 2009 prohibits the sale of nonprescription drugs via mail.  However, as a provisional measure, regular users and inhabitants of remote islands who do not have access to pharmacies or drug stores are allowed to purchase nonprescription drugs via mail until the end of May 2013.  This study involves a survey on the purchasing of nonprescription drugs by Internet-illiterate inhabitants of the remote Goto Islands, Nagasaki Prefecture, Japan.
    Methods: Our process began with the distribution of questionnaires via mail to inhabitants of the remote Goto Islands, of whom 3,819 were randomly selected.  The responses were sent between January 22 and February 26, 2011.  We analyzed problems presented by 522 inhabitants who were Internet-illiterate.
    Results: The results revealed that 57.3% of the respondents living on large islands—with pharmacies, drug stores, and pharmacists— (e.g., Fukueshima) and 85.3% of respondents living on small islands scattered around large islands—with none of the abovementioned amenities— (e.g., Maeshima) were Internet-illiterate.  Additionally, a majority of the respondents (more than 80%) felt no need to purchase nonprescription drugs over the Internet.  However, considering that a handful of these inhabitants do, or will at some time need to purchase nonprescription drugs over the Internet, we strive to establish an optimal system for supplying medications to these Internet-illiterate inhabitants.
    Conclusion: Community pharmacists need to establish close relationships with the Internet illiterate (particularly those living on small islands) and promote the overall appropriate use of medicinal products.

    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: Macrolide therapy has been recommended as an effective treatment for pediatric otolaryngology patients with conditions such as chronic sinusitis and otitis media with effusion.  However, in many cases, a relapse may occur after cessation of treatment.  Therefore, patients are compelled to continue taking antibiotics.  In this paper, we examined the relationship between the duration of therapy and period to relapse on the basis of prescription information and literature research.
    Methods: To evaluate the therapeutic doses, we investigated the clinical doses of erythromycin and clarithromycin used for pediatric patients in a community pharmacy from January 2009 to July 2009.  Further, we performed literature searches on the doses of both drugs using Igaku-Chuo-Zasshi databases (from 1983 to 2011) and compared the data obtained with the clinical doses.  Accordingly, the oral doses of macrolides were classified as a low dose or normal dose.  We analyzed the relationship between the administration period and the cessation period, which was defined as the period from the cessation of the treatment to relapse.
    Results: Review of the 17 selected reports and the clinical doses showed that the maximum dose of erythromycin was 15 mg/kg/day and that of clarithromycin was 8 mg/kg/day during therapy.  When both cephem or penicillin antibiotics and low-dose macrolides were taken continuously during the administration period, a weak correlation was observed between the administration period and the cessation period.
    Conclusion: These results may be useful for the appropriate use of antibiotics and for preventing relapse in pediatric otolaryngology patients.

    Objective: The Hyogo Hospital Pharmaceutical Society has been conducting an original pharmacy postgraduate education program, “lifelong learning program (to nurture pharmacy specialists)”, since 2002 using the Internet.  To understand the status of using this program, this study employed a questionnaire survey involving all registered members.
    Methods: Subjects were all members (1,870) of the society.  Questionnaires were distributed and collected by mail.
    Results: Only 20.1% of the members had experience of using the program, and the frequency of using it was less than once per 6-12 months in 60% of the members.  Their level of awareness concerning the acquisition of credits for lifelong learning was 36.9%.  The program category they wished to take was an infection-related program in 26.1% of the members, which was the highest.
    Conclusion: As reasons for only a small number of members using the program, the following are considered: loss of user’s ID and password required to login, and lack of awareness concerning the acquisition of credits for lifelong learning offered by the Japanese Society of Hospital Pharmacists.  As future issues, we must encourage members to obtain a new password and be proactively involved in preparing new program categories that the members wish to take, in order to promote the continuous use of the program.

    Objective: The present study investigated awareness and knowledge about clinical trials among pharmacists working in the Nagano Hokushin area as well as their contribution to the enlightenment of clinical trial.
    Methods: A questionnaire survey of clinical trials was conducted to evaluate levels of interest, impressions, sources of information, and knowledge among hospital and community pharmacists.
    Results: We received responses from 77 hospital and 67 community pharmacists.  The levels of interest in clinical trials were not significantly different between hospital and community pharmacists.  About impressions, hospital pharmacists thought that clinical trials were “a new development.”  Contrarily, community pharmacists thought that clinical trials were “a field that they were seldom concerned with.”  About sources of information, hospital pharmacists found that “study meetings” were the most informative.  More community pharmacists than hospital pharmacists chose “general reports, for example, newspapers and televisions” as a source of information, and similarly more community pharmacists indicated that they had “few opportunities for obtaining information about clinical trials.”  About knowledge, the percentage of correct answers about clinical trials between hospital and community pharmacists was not significantly different.  A higher percentage of community pharmacists than hospital pharmacists answered unknown.
    Conclusion: Hospital and community pharmacists had different impressions and knowledge about clinical trials probably because of differences in sources of information and its access.  Henceforth, study meetings involving educational material about clinical trials should be held for discussing fundamental knowledge about the methods and structure of clinical trials and for discussing case studies wherein patients consult pharmacists about clinical trials.

    Objective: As part of the revision on remuneration for medical services in 2012, a new system has been implemented to allow an additional fee for inpatient pharmaceutical services to be added to the basic hospitalization fee.
    Methods: We at Kitasato University Kitasato Institute Hospital satisfied all institutional requirements for the new system and were preparing to introduce it from April 2012; however, there was concern about the increased workload due to the additional work of preparing diaries for pharmaceutical services used in calculating the additional fee.
    Results: We therefore developed a database titled Diary System for Inpatient Pharmaceutical Services for the preparation and management of diaries.  This system allows pharmacists from various divisions to enter data simultaneously and realizes the unified management of records of services performed at various places in the pharmacy.
    Conclusions: Since entered data are automatically reflected in the inpatient pharmaceutical service diary and the monthly summary, an advantage compared to paper diaries in terms of efficiency may be expected.  Furthermore, the monthly summary of the number of service hours by ward and service type may also be used for service analysis.
