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.

Pneumonia is common among elderly patients and the incidence among older adults is increasing in aging societies. If pulmonologists were to treat all cases of pneumonia, their work volume would be immense and the risk of burnout would increase. We reviewed cases of consecutive patients 70 years of age or older who were treated for pneumonia between November 2017 and October 2018 at Akita Kousei Medical Center. Of a total of 372 patients recruited for this study (214 men, mean age 85.6 years), 288 patients recovered and 84 (29.2%) died. The duration of admission differed significantly between the cardiovascular department and surgery department (p=0.03), between the renal unit of the internal medicine department and the neurosurgery department (p=0.01), and the renal unit of the internal medicine department and the surgery department (p=0.0005). Outcome was not significantly different among departments. It is crucial that pulmonologists and non-pulmonologists collaborate to treat pneumonia in old adults.

Objective: Difficulty in extracting tablets from a press through pack (PTP) is believed to reduce prescription drug compliance.　This is a particularly serious issue for the elderly or for those who have physical disabilities affecting the fingers.　In this study, the squeezing force necessary to extract tablets from PTPs was measured for 33 commercial tablet products using a force gauge (FG).　Additionally, a sensory test was conducted to determine the degree of difficulty in extracting tablets from PTPs by squeezing, and the correlation between the difficulty measure and squeezing force was evaluated.Methods: The squeezing force for 33 products was measured by FG.　The sensory test was conducted with 64 subjects.　Four products, each with a different squeezing force, were used for the sensory test.　In the test, each subject ranked the products in order according to the amount of force required to extract the tablets.　Each product's total score was used in the statistical analysis.Results: The average squeezing force of the 33 products was 33.1 ± 6.9 〔N〕, and significant differences were observed among the products.　The sensory test revealed that each subject could significantly distinguish the amount of force required to extract the tablets from each product.Conclusion: A positive correlation was observed between the squeezing force obtained using FG and the results from the sensory test.　This suggests that squeezing force can be used as an indicator for the usability of the product.　Therefore, the degree of difficulty in extracting tablets from PTPs should be considered when selecting drugs for the elderly.

Objective: We conducted a meta-analysis on the suppressive effect of resistant maltodextrin on post-prandial blood glucose elevation, which is approved in Japan as food for specified health use, and the following is allowed to be indicated on the label “it is suitable for consumption by those who are concerned about their post-prandial blood glucose levels because the absorption of sugars is abated by the action of dietary fiber (resistant maltodextrin).”
Method: Our literature search covered Ichushi-Web (Japan Medical Abstracts Society), Japan Science and Technology Information Aggregator, Electronic (J-stage), Google Scholar, and PubMed databases and extracted English and Japanese publications on randomized, double-blind, controlled studies comparing resistant maltodextrin and a control in Japanese subjects for the reduction of areas under the blood glucose response curves at 30, 60, and 120 min after eating as an efficacy index.
Result: Among these publications, four articles with a Jadad score (an assessment of the quality of randomized controlled studies) of ≥ 3 were included in the meta-analysis.  Significant inhibitory effects were confirmed from areas under the blood glucose response curves at 30, 60, and 120 min after eating in the meta-analysis that was performed to evaluate the effects of resistant maltodextrin on post-prandial blood glucose elevation in Japanese individuals.
Conclusion: However, we were not able to test for publication bias because the number of extracted publications was small, and thus, additional research and case studies are warranted.

We implemented a questionnaire survey targeting mothers who are in child care and had participated in consultations regarding drugs and diseases. We examined the future roles of community pharmacists by exploring the mothers’ concerns and, anxieties about child cares and their backgrounds, and their expectations for profession of community pharmacist. Mothers have listed anxiety and concerns of child care about “dermatitis such as rash and atopic eczema”; “food allergies”; “infectious diseases such as measles, chicken pox, and mumps”; and “side effects of vaccination”. In addition, most of them indicated their own concerns and anxiety about “solutions to children’s illnesses.” Despite their anxieties and concerns, however, approximately 60% of the mothers have never consulted with community pharmacists. Among them, approximately a half of them indicated the following three reasons why they have never consulted with pharmacists: “I have nothing to talk about,”, “I do not know what I should talk about,”, and “I was not sure if it was alright to talk about my concerns.”. From these results, we concluded that community pharmacists in the future should improve their communication skills and inform their availability to consult about medicine and disease to local residents.

Objectives To identify the ankyrin-B gene mutations that cause long QT syndrome (LQTS) and determine the prevalence of such mutations in Japanese patients with LQTS. Methods We conducted a search for ankyrin-B gene mutation in 78 unrelated patients with LQTS (28 males and 50 females, aged 2 to 89 years). With informed consent from all the subjects and/or their parents, genomic DNA was purified from the white blood cells of the patients and amplified using polymerase chain reaction (PCR). Single-strand conformational polymorphism (SSCP) analysis of the amplified DNA was performed to screen for mutations and aberrant SSCP products were isolated and sequenced by dye terminator cycle sequencing method using an automated fluorescent sequencer. PCR and restriction fragment length polymorphism (PCR-RFLP) analysis was carried out to further confirm the missense mutations by comparison with samples from 150 normal healthy individuals.Results We identified a T to A transition mutation at position 4 603 in exon 40, resulting in the substitution of arginine for a tryptophan at amino acid residue 1 535 (W1535R) in the regulatory domain of 220-kD ankyrin-B, which is a highly conserved domain shared by different species. Conclusions This novel missense mutation in the ankyrin-B gene may bea cause of type 4LQTS. Ankyrin-B gene mutation might not play the major role in LQTS in Japanese.

We reviewed our experience with 19mm size aortic valve prostheses for cases with small aortic annulus. Forty-six patients operated on between 1990 and Septembr 2002 were enrolled in this study. Clinical late assessment was performed to evaluate the incidence of valverelated complications, residual transprosthetic gradient, left ventricular mass index (LVMI), and NYHA functional class. Postoperative echocardiography was performed to evaluate hemodynamic performance of the prostheses. Follow up was 1 to 12.7 years (mean 5.3±3.6). There was no hospital mortality (0%). Actuarial survival rates at 10 years were 81.4±1.5%. The late postoperative peak gradient was 25±11mmHg. LVMI was significantly reduced in late phase. NYHA functional class significantly improved in the late period. Although 19mm size aortic valve prosthesis remains small transprosthetic pressure gradient, LVMI significantly reduced and patient activity was satisfactory maintained in the late period.

Abdominal aortic aneurysms (AAA) are frequently associated with clinically significant coexistent ischemic heart disease (IHD). Cardiac events are the most common cause of death after AAA repair. Preoperative coronary evaluation and revascularization have been recommended to reduce postoperative cardiac complications following AAA repair. In this study, we retrospectively reviewed all patients who underwent AAA repair and compared operative results in patients with and without IHD. Of 388 patients who underwent elective AAA repair, 382 (98.5%) had aortography and coronary angiography for preoperative evaluation. Significant coronary artery disease was seen in 124 patients (32.5%). As a result of the evaluation, 46 patients (12.0%) were considered candidates for medical therapy, 18 for percutaneous coronary intervention (PCI), and 60 for coronary artery bypass grafting (CABG). In 24 patients (6.3%) who needed CABG and had large sized AAAs (>60mm), simultaneous CABG and AAA repair were performed. In the remaining 36 patients (9.4%) who needed CABG and had medium sized AAAs (40mm<, <60mm), staged operation was performed. We performed retrospective review comparing postoperative cardiac events and operative mortality among these treatment groups. There were 5 operative deaths (5/388, 1.3%) in patients following AAA repair. There were 2 operative deaths (2/124, 1.6%) in patients with significant IHD and 3 deaths (3/258, 1.2%) without IHD. In patients with IHD, 1 patient who received medical therapy died of acute renal failure and another one who received PCI died of acute myocardial infarction. There were no operative deaths or cardiac-related events in patients who received CABG before or concomitant AAA repair. There was only 1 cardiac-related event in all patient groups following AAA repair. Coronary arteries were preoperatively evaluated in almost all patients with AAA. If IHD was significant, the treatment for the IHD preceded AAA repair. Our strategy succeeded in reducing operative mortality and cardiac-related events in patients with both AAA and IHD. If a patient with a large sized AAA (>60mm) needs CABG, one-stage operation is recommended.

Dacron prostheses are the most widely used grafts in replacement procedures for abdominal aortic aneurysms, but they are not perfect grafts. We encountered a rare case of late graft complication. A 66-year-old man was admitted to our hospital with a pulsatile mass in an abdominal operation scar. He had received placement of a Y-shaped Cooley double velour knitted Dacron graft 18 years previously. Computed tomography and angiography demonstrated graft dilatation and an aneurysm. After resection of the graft aneurysms, the operative findings showed a non-anastomotic aneurysm formation due to longitudinal division near the graft guideline. In this case, this graft failure may have been due to the deterioration of the filter of the Dacron prosthesis itself. Therefore it is important to perform careful long-term follow-up in patients with implanted Dacron arterial prostheses.

Bypass grafting from the ascending thoracic aorta to the common iliac artery was performed to manage proximal hypertension in a patient with atypical coarctation of the thoracic aorta. The patient's history was significant for an acute aortic thrombosis at the level of the diaphragm for which she underwent an axillo-bifemoral bypass grafting as an emergency operation. Although she was doing well following the initial bypass grafting, the second bypass grafting was required to treat proximal hypertension refractory to medical management. The axillo-femoral bypass graft had a smaller diameter and a longer subcutaneous distance, and the blood supply to the abdominal viscera may have been insufficient. The proximal hypertension was well controlled following ascending thoracic aorta to common iliac bypass, because the diameter (16mm) of the graft is larger than that of the axillo-bifemoral bypass graft (8mm).
