Objective: The presence of a short, angulated neck in endovascular aneurysm repair remains challenging. The fish-mouth shape of the AORFIX AAA endograft enables trans-renal fixation, which can be advantageous in such cases. However, it is difficult to align the bottom line of the fish-mouth in a renal artery with an angulated neck. Here we devised a breakthrough technique to facilitate accurate fish-mouth positioning and achieved positive results. We then observed the ex vivo behavior of fish-mouth fixation of the AORFIX AAA endograft using this technique. Methods: A model of an abdominal aorta with a renal artery was created of porcine aortic vessels. Typical proximal touch-up ballooning was performed for reference. Kissing touch-up ballooning, which we named the Aligning Orifice of the Renal artery with fish-mouth FIXation (AORFIX) technique, between the aorta and the renal artery was performed as an interventional model. Results: In the reference model in which the endograft was deployed just below the renal artery, the bottom line of the fish-mouth was raised to cover the renal artery via touch-up ballooning. Unfortunately, its position did not improve with balloon angioplasty of the renal artery because the ring stents returned to the covered position after balloon deflation. In another reference model in which the endograft was deployed far enough below the renal artery, the bottom line of fish-mouth wasn't raised beyond that. In the interventional model with the AORFIX technique, the bottom line of the fish-mouth was anchored at the lower end of the renal artery orifice. The ring stents were shaped to fit the orifice, and clearance of the renal artery was secured. Conclusion: This ex vivo observations of fish-mouth behavior support our surgical experiences. The AORFIX technique effectively affixed the fish-mouth to the renal artery orifice and created a longer-lasting effect. These results suggest that the AORFIX technique can be a good option in cases of challenging endovascular aneurysm repair with a short, angulated neck.

Objective: Eye drops may contain certain preservatives, and there is concern in patients who use them on a daily basis for the treatment of diseases, including corneal epithelial disorder and glaucoma. PF eye drops (Rohto Nitten Co., Ltd.) are used widely; however, their usability may be difficult in patients prescribed these medications for the first time. Therefore, fact-finding was performed on the usability of PF eye drops, particularly the difficulty in squeezing out these eye drops. Methods: The squeezing forces for various eye drops in 11 different shapes were determined. A sensuality evaluation examination on “the easiness of pushing out the eye drops” was performed in addition to a questionnaire survey targeting patients who used eye drops at a community pharmacy. Results: The squeezing forces ranged from 2.0 to 17.1 N. This study showed that the squeezing force tended to increase as the drop got closer to the opening of the container. Significant differences in the sensuality examination scores were found: 3.09 points for Santen Pharmaceutical Co., Ltd.; 3.07 points for Senju Pharmaceutical Co., Ltd.; 2.47 points for Sawai Pharmaceutical Co., Ltd.; and 1.37 points for PF eye drops for any place other than Santen and Senju (p<0.001). Conclusion: When eye drops were prescribed for an elderly individual, the pharmacist considered it necessary to suggest an alternative agent to the doctor depending on body function. In addition, it is important to explain to the patient that an additional squeezing force is required to push out the drop as it gets closer to the opening of the container.

Background/Aims: Although risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records. Methods: We used health checkup records between April 2004 and March 2014 at 9 institutions in Japan. A multivariate logistic regression analysis was performed to evaluate associations of baseline clinical parameters with RE. The time courses of the clinical parameters of RE subjects were compared with those of non-RE subjects by the mixed-effects models for repeated measures analysis or longitudinal multivariate logistic analysis. Results: Initial data were obtained from 230 056 individuals, and 2066 RE subjects and 4132 non-RE subjects were finally included in the analysis. Body mass index, alanine aminotransferase, smoking, acid reflux symptoms, hiatal hernia, and absence of atrophic gastritis at baseline were independently associated with RE. The time courses of body mass index, fasting blood sugar, triglyceride, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, percentages of acid reflux symptoms, feeling of fullness, and hiatal hernia in the RE group were significantly worse than in the non-RE group. Conclusions The RE group displayed a greater worsening of the clinical parameters associated with lifestyle diseases, including obesity, diabetes, hyperlipidemia, and fatty liver for 5 years before RE onset compared with the non-RE group. These results suggest that RE is a lifestyle disease and thus lifestyle guidance to at-risk person may help to prevent RE onset.

Objective: Confirmation by pharmacists of brought-in drugs is not only limited to identification of drugs, but also requires prescription design and proposals based on the background of patients and evaluation of associated information. In this study, we analyzed the content of brought-in drugs related PreAVOID reports in our hospital according to the years of pharmacist experience in order to help educate pharmacist for better brought-in drugs confirmation.Method: Various interventions regarding brought-in drugs were compared between two groups: pharmacists with >6 years of experience (group H) and those with < 5 years of experience (group L). PreAVOID reports, which related to drugs brought in by patients admitted to the Ogaki Municipal Hospital between April 1, 2018 and March 31, 2019 were assessed.Result:The PreAVOID reporting rate for the number of brought-in drugs confirmed was higher in group H (1.56%) than in group L (1.12%) (odds ratio 1.399, p = 0.023). The PreAVOID reporting rate when reporting was based solely on prescription information did not differ between these two groups, but when patient background, including disease-related information, was included with prescription information, the rate was higher in group H (0.80%) than in group L (0.30%) (odds ratio 2.725, p < 0.001). Group H provided more reports related to unnecessary drugs.Conclusion: The involvement of pharmacists in the evaluation of brought-in drugs is important when reviewing subsequent medical treatments. Our findings suggest that to improve the quality of treatment, it is necessary to provide appropriate newcomer education, such as conducting case studies using PreAVOID cases.

Methods: Sixty fresh-frozen lumbar vertebrae from 6-month-old pigs were used. Before screw insertion, the CT values of the screw path were obtained for each sample. Specimens were then randomly divided into three equal groups. Each group had one of three pedicle screws inserted: 4.0-mm LEGACY (4.0-LEG), 4.5-mm LEGACY (4.5-LEG), or 4.5-mm SOLERA (4.5-SOL) (all from Medtronic Sofamor Danek Inc., Memphis, TN, USA). Each screw had a consistent 30-mm thread length. Axial pull-out testing was performed at a rate of 1.0 mm/min. Correlations between the CT values and pedicle screw pull-out strength were evaluated using Pearson’s correlation coefficient analysis. Results: The correlation coefficients between the CT values of the screw path and pedicle screw pull-out strength for the 4.0-LEG, 4.5-LEG, and 4.5-SOL groups were 0.836 (p <0.001), 0.780 (p <0.001), and 0.873 (p <0.001), respectively. Greater CT values were associated with greater screw pull-out strength. Conclusions The CT values of the screw path were strongly positively correlated with pedicle screw pull-out strength, regardless of the screw type and diameter, suggesting that the CT values could be clinically useful for predicting pedicle screw pull-out strength.

Objective: Several evidence-based practice guidelines have been developed to better treat bipolar disorder. However, the articles cited in these guidelines were based on clinical or basic studies with specific conditional settings and were not sufficiently based on real-world clinical practice. In particular, there was little information on the doses of mood stabilizers. Methods: The MUlticenter treatment SUrvey on BIpolar disorder in Japanese psychiatric clinics (MUSUBI) is a study conducted to accumulate evidence on the real-world practical treatment of bipolar disorder. The questionnaire included patient characteristics such as comorbidities, mental status, treatment period, Global Assessment of Functioning (GAF) score, and details of pharmacological treatment. Results: Most patients received mood stabilizers such as lithium (n = 1,317), valproic acid (n = 808), carbamazepine (n = 136), and lamotrigine (n = 665). The dose of lithium was correlated with age, body weight, number of episodes, depression and GAF. The dose of valproic acid was correlated with body weight, number of episodes, presence of a rapid cycle and GAF. The dose of carbamazepine was correlated with age, mania, and the presence of a rapid cycle. The dose of lamotrigine was correlated with the number of episodes, depression, mania, psychotic features, and the presence of a rapid cycle. Doses of coadministered mood stabilizers were significantly correlated, except for the combination of valproic acid and lamotrigine. Conclusion The dose of mood stabilizers was selectively administered based on several factors, such as age, body composition, current mood status and functioning. Further prospective studies are required to confirm these findings.

A 40-year-old woman visited our emergency room (ER) with fever and shaking chills. Blood cultures for suspicion of urinary tract infection revealed bacteremia two days later. Since Streptococcus mitis was detected, infective endocarditis was strongly suspected. In addition to her history of dental calculus removal, careful cardiac auscultation revealed a continuous murmur, leading to the existence of patent ductus arteriosus (PDA). PDA was confirmed by echocardiography and 3D-CT angiography. The patient was successfully treated by antibiotics and then received transcatheter PDA closure. Careful auscultation after detection of bacteremia led to a diagnosis of PDA.

BACKGROUND/AIMS: Rikkunshito (TJ-43), an herbal medicine, has been demonstrated to relieve gastroesophageal reflux symptoms. However, the effects of TJ-43 on esophageal motor functions have not been fully determined. This double-blind crossover study was performed to investigate the effects of TJ-43 on esophageal motor functions and gastroesophageal reflux. METHODS: The subjects were 10 normal male volunteers. Lower esophageal sphincter pressure and esophageal body peristaltic contractions with and without 1-week administration of TJ-43 were examined in a crossover fashion. Post-prandial gastroesophageal reflux was also determined using a multi-channel impedance pH dual monitor. RESULTS: TJ-43 at a standard dose of 7.5 g/day did not significantly augment esophageal peristaltic contraction pressure measured in the proximal, middle and distal segments of the esophagus, whereas increment of resting lower esophageal sphincter pressure was observed in a supine position. In addition, TJ-43 administration did not decrease post-prandial gastroesophageal acid, non-acid reflux events or accelerate esophageal clearance time. CONCLUSIONS: TJ-43 at a standard dose did not have a significant effect on esophageal motor activity or gastroesophageal reflux in healthy adults.

Objective : To provide efficient medical care to patients taking warfarin by developing a system for sharing prothrombin time-international normalized ratio (PT-INR) monitoring data between clinic and pharmacy ; and to verify the functionality of this system.
Methods : Before a clinic appointment, patients visited a pharmacy to self-monitor PT-INR levels with the rapid measuring device Coagucheck. Pharmacists noted the following on a form shared between the clinic and the pharmacy : 1) compliance, 2) side effects, 3) diet, and 4) PT-INR. On the basis of this information, they noted their opinions on the appropriate warfarin dose. Each patient submitted the form to the clinic doctor, who then prescribed warfarin on the basis of the information recorded. After the consultation, the patient took this prescription to the pharmacy to obtain the required medication, and received from the pharmacist the dosage information based on the doctor's instructions. Thus, the sequence of the patient's visits was pharmacy-clinic-pharmacy.
Results : From one pharmacist's report, it was apparent that one patient whose PT-INR level was outside the target range was occasionally skipping a warfarin dose because of a misunderstanding about the treatment. The pharmacist recorded the patient's information on the form to inform the doctor. After consultation with the doctor, the pharmacist gave a detailed explanation on the purpose of taking warfarin. As a result, patient compliance improved and the PT-INR reached the target level after one month.
Discussion : Development of this system revealed that patients can receive appropriate warfarin treatment when information on PT-INR becomes available during clinical consultation and compliance is achieved. The system for sharing the patient's self-monitored PT-INR data between clinic and pharmacy is considered beneficial for the patient.
