Anticancer drug preparation by pharmacists is a critical task directly related to medical incidents. This study examined the factors influencing medical errors in chemotherapy, that is, errors by specialist pharmacists (CPh) and pharmacists in other departments (NCPh), by measuring their gaze during the preparation of anticancer drugs. The eye-tracking results showed that the gazing time of NCPh was significantly longer than that of CPh for items such as “preparation of a closed-system device” and “preparation of the syringe” and all preparation times (P < 0.05). The NCPh were not assigned to prepare drugs on a regular basis, indicating their lack of familiarity with the process. There was no significant difference in gaze ratio between CPh and NCPh. This outcome was suggested to be a result of the use of an anticancer drug preparation support system. The results for the pupil diameter variation rate showed that NCPh were significantly more mydriatic in the “mixing injections” category than CPh. However, CPh tended to be more mydriatic in the “checking” category. CPh exhibited a smooth workflow and focused on the important items to be checked. This study showed that the differences in procedure flow and concentration points may lead to errors. Furthermore, the results are of interest from the perspective of medical incident prevention. They will be useful in identifying potential human factors, such as where the pharmacist focuses their attention by measuring eye movements.

In recent years, medical institutions have taken a variety of measures to prevent medical incident. In addition, progress has been made toward the development of a fully automated system for the purpose of medicine dispensing. However, automating the dispensing, or having it replaced by artificial intelligence (AI) will not, eradicate human error. Thus, measures against human error will continue to serve as an important topic. Therefore, hospitals are required to improve the efficiency of the pharmacy department. For these purposes, attention has now shifted to Supply Processing and Distribution (SPD). In this study, we measured for the gaze of the pharmacist and SPD, and examined the factors affecting dispensing error;moreover, we examined prevention of the human error. In the results of the eye tracking, SPD members tended to spend a greater number of gaze time and gaze counts, for each medicine, on “medicines” and “picking lists,” than pharmacists. On the other hand, when pharmacists picking medicines, they performed various work operations in parallel, such as checking the prescription and looking the next shelf location. It was conjectured that SPD members had more clearly defined items to check when picking, compared to pharmacists. This may have possibly led to a lower chance of dispensing errors being introduced by SPD members. These results suggest that the process of selection is not a mandatory requirement of pharmacists during the action of dispensing. Instead, SPD members, pharmacy assistants, or automatic dispensing devices could serve as substitutes for picking. It is suggested that pharmacists should spend more time and effort on prescription inspection, medicines checking and dosing operations.

Medical incidents have been collected, analyzed and built up preventive measures by each medical institution for a long time. For powdered medication, there is the problem that it is difficult to tell at a glance the quantity of the active ingredient in the medication that has been dispensed and the quantities that have been mixed together. Therefore, special prevention measures are considered essential. In this study, we examined the work content of pharmacists’ powdered medication dispensing, using an eye-tracking technology of measuring a human eye movement, and studied on factors that affect medical incident. Participants were five pharmacists with 8 to 26 years of working experience (expert), and five pharmacists with less than one year of working experience (newcomer). Gaze measurement experiments were implemented for powdered medication dispensing during regular work activity. The gaze measurement equipment used was Tobii Pro Glasses 2. Based on the results of the eye tracking, newcomer had a longer dispensing time than expert for all powdered medication dispensing. In particular, it was suggested that there is a close relationship to “years of experience” and “weighing and mixing skills.” Experts did unwasted and efficient movements, when preparing the dispensing apparatus, taking medications from the shelves, and scanning the barcode in the powders dispensing checking system. These movements led to shorter working time in experts. In contrast, newcomer had individual differences at the dispensing. Even with the same pharmacist, the work progression differed depending upon the prescription. Therefore, it is thought that the factor of common error was inadequate check and overlooked. The state that it’s messy on the workplace is also considered highly likely to cause dispensing mistakes. At the weighing, expert started weighing after the inspection of the prescription and checking weighed amount. However, certain newcomer dispensed to depend on the powders di

The corrosion behavior of a titanium-5% tantalum alloy (Ti-5Ta) in hot nitric acid condensate was investigated to understand aging behavior of reprocessing equipments. On the basis of long-term immersion tests, it was determined that the corrosion of Ti-5Ta in nitric acid condensate is accelerated with an increase in the concentration. The corrosion rate was nearly constant during the immersion test and the coupons suffered from uniform corrosion. In addition, it is important to note that the nitric acid concentration in the condensate increased on addition of metal salts to the heated nitric acid solution. The larger valence of metal ions was contributed to the increase in the concentration of nitric acid condensate. Consequently, the metal salt in the heated nitric acid solution accelerates the corrosion of Ti-5Ta in the condensate. Therefore, the nitric acid condensate condition should be carefully considered for the corrosion environment of titanium and its alloys.

Background: Xanthogranulomatous inflammation of the female reproductive organs is a rare chronic inflammation. In most reported cases, the lesion was limited to the endometrium and fallopian tubes. Here, we report two cases of xanthogranulomatous inflammation of the myometrium with a history of endometrial biopsy. Case Reports: In two cases, myometrial xanthogranulomatous inflammation destroyed the myometrium. This inflammation developed into surrounding pelvic organs, resulting in uterine perforation. Conclusion: When inflammatory lesions are found after intrauterine manipulation, the possibility of developing xanthogranulomatous inflammation should be considered. If antibiotics are ineffective, prompt surgical treatment is necessary.

Aim The objective of this study was to analyze the oral health among Japanese adults, with and without diabetes mellitus. Methodology The subjects were 518 community residents aged 20 to 91 years in Japan, who participated in the ＂Akita health and nutrition survey＂ and the ＂Akita dental disease survey＂, conducted in 2006. The surveys comprised a self-administered questionnaire, along with medical and dental examinations. Results Using the community periodontal index （CPI）, the mean numbers of sextants presenting codes 0, 1 and 2 were significantly lower in diabetics than non-diabetics among the 59 years or younger age group. Although the mean numbers of sextants with codes 0, 1 and 2 among the 60 to 69 years age group were lower, and sextants with a code X among the 59 years or younger age group were higher in diabetics than non-diabetics, no statistically significant differences were detected. The tendency of lower mean numbers of natural teeth and functional tooth units in diabetics than non-diabetics was observed, however no differences were statistically significant. Conclusion The outcome of periodontal disease seemed to be influenced by the diabetic state to some degree, but a clear association between diabetes and oral health status was not found.
