Background: This study surveyed pharmacists registered with the Yamaguchi Prefectural Pharmacists Association to determine the key elements of tablet printing design that enhance visibility and distinguishability during dispensing.Objectives: The purpose of this study is to identify suitable design components for tablets that enhance visibility and distinguishability by utilizing text data.Methods: Given the high risk of medication errors due to similar-looking tablets, the study employed KH Coder for text mining analysis of free-text responses.Results: Results indicated that design elements such as "horizontal writing," "straight lines, " and "emphasis on characters" significantly improve visibility and distinguishability, particularly for similar-looking tablets. The findings from this study provide specific guidelines for optimal tablet design, aiming to improve pharmacists' efficiency and enhance medication safety.Conclusions: KH Coder proved to be a valuable tool for analyzing qualitative data in the medical field. While the study focused on pharmacists in Yamaguchi Prefecture, expanding the survey to a national scale is recommended to validate and generalize the findings. This research supports the development of standardized tablet designs that can minimize dispensing errors and ensure patient safety, highlighting the importance of effective tablet printing design in pharmaceutical practice.

Background: Imprinting tablet bodies is an essential element for the safe use of pharmaceuticals. It has been observed that reports on tablet imprint design that incorporate pharmacists’ perspectives are scarce. Objectives: The aim of this study was to provide a better understanding of the concept of universal design in tablet body identification and differentiation, specifically in two scenarios: normal handling of tablets and encountering tablets with similar appearances. Methods: A survey was conducted among pharmacists registered with the Yamaguchi Prefecture Pharmaceutical Association to collect data on optimal tablet imprint designs from a dispensing perspective. Results: Analysis of the survey results indicated that: 1. In normal use of tablets, a simple design with “horizontal Kana notation without emphasis on one character” was most preferred. 2. In cases where tablets were similar in appearance, designs such as “horizontal Kana notation with an underline on one character” and “horizontal Kana notation with emphasis on one character” were preferred. Conclusions: The study may indicate that certain tablet imprint designs may enhance the ability to differentiate and recognize pharmaceuticals, particularly in cases where tablets have similar appearances. To aid in distinguishing tablets with similar appearances, it is suggested that the design should incorporate ‘horizontal Kana notation’ and give emphasis to one character. This design has been shown to result in a clear improvement in identification. It is recommended that tablet imprint designs prioritize high readability for pharmacists and provide appropriate pharmaceutical information. When considering similarity with other tablets, it may be advisable to use ‘emphasis on one character’ as a universal design for differentiating and identifying tablet bodies.

Journal of Neurogastroenterology and Motility 2024;30(2):229-235
Background/Aims:
Although certain allergic diseases have been reported to be associated with the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), it is unclear whether the presence of multiple allergic diseases further increases the prevalence of FD and IBS.The aim of this study is to determine this issue in young people.
Methods:
A cohort of 8923 Japanese university students was enrolled and diagnoses of FD and IBS were confirmed using Rome III criteria.Allergic disorders diagnosed at medical institutions were obtained by means of a self-administered questionnaire.
Results:
The prevalence of FD, IBS, and their overlap was found to be 1.9%, 6.5%, and 1.1%, respectively. Pollen allergy was independently positively correlated with FD, IBS, and overlap of FD and IBS. Allergic rhinitis was positively linked to IBS. Drug allergy was positively associated with FD. The presence of multiple allergic diseases was positively correlated with FD and IBS (FD: adjusted OR for 2 allergic diseases: 1.95 [95% CI, 1.24-2.98], P for trend = 0.003; and IBS: adjusted OR for 1 allergic disease: 1.40 [95% CI, 1.15-1.69], 2 allergic diseases 1.47 [95% CI, 1.12-1.91], and 3 or more allergic diseases: 2.22 [95% CI, 1.45-3.28], P for trend = 0.001). Additionally, the concomitant existence of multiple allergic diseases was also demonstrated to have a trend that correlated with the overlap of FD and IBS (P for trend = 0.018).
Conclusion
Allergic disease multimorbidity is positively correlated with the prevalence of FD and IBS in a young population.

Introduction: In patients receiving opioids, relief of cancer pain by palliative radiation therapy or other means can lead to opioid discontinuation and subsequent withdrawal symptoms, such as agitation, insomnia, and diarrhea, due to opioid-related physical dependence. Appropriate steps should be taken to prevent these symptoms. Case: A 72-year-old man underwent surgery for esophageal cancer. He developed low back pain and right lower limb pain, and was diagnosed with sacral and right iliac bone metastases. His pain was resistant to oxycodone (OXC), so he was simultaneously treated with methadone (MDN) and palliative radiotherapy. His pain gradually decreased, and MDN was tapered and switched to OXC, which was in turn discontinued at 20 mg/day at the patient's strong request. After OXC discontinuation, akathisia, anxiety, and diarrhea appeared as withdrawal symptoms. These were treated with immediate-release OXC, transdermal fentanyl, and suvorexant. Discussion: When discontinuing opioids, dose reduction below 10% per week is recommended, de-escalation to the lowest possible dose should be followed by cessation. In case of withdrawal symptoms, immediate-release opioids may be used, and opioid tapering should be attempted in parallel with symptom control.

Journal of Neurogastroenterology and Motility 2022;28(2):276-282
Background/Aims:
Evidence regarding the association between body mass index (BMI) and functional dyspepsia (FD) in the Asian population is limited.Further, no study has evaluated this issue in young people in Asian and Western populations. Thus, we aim to investigate this issueamong young Japanese people.
Methods:
The study subjects comprised of 8923 Japanese university students. BMI was divided into 4 categories (quartiles) on the basis of thestudy subjects’ distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, overweight, and obesewas BMI < 18.5 kg/m2 , 18.5 ≤ BMI < 25 kg/m2 (reference), 25 kg/m2 ≤ BMI < 30 kg/m2 , and 30 kg/m2 ≤ BMI, respectively. The definition of FD was based on the Rome III criteria.
Results:
The prevalence of FD was 1.9% in this cohort. The lowest BMI was independently associated with FD after adjustment (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.46-3.67); P for trend = 0.001). The lowest BMI was independently associated with FD in women but not in men (OR, 2.94; 95% CI, 1.59-5.77; P for trend = 0.001). Leanness was independently associated with FD in total and in women but not in men (total: adjusted OR, 2.01; 95% CI, 1.40-2.86) and women (OR, 2.19; 95% CI, 1.35-3.45). However,interaction analysis showed no significant difference for sex.
Conclusions
Among young Japanese people, BMI may be independently inversely associated with FD. Leanness may be an independent associated factor for FD in the young Japanese women.

Background/Aims:
Functional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort.
Methods:
In this study, we enrolled 8923 Japanese university students. FD is diagnosed based on the Rome III criteria. Eating habits and frequency of meals were investigated using a self-administered questionnaire.
Results:
The FD subjects had a younger mean age, a lower body mass index, and a lower proportion of men compared to the non-FD subjects.An independent positive association between skipping breakfast and/or lunch and FD was found (adjusted ORs were 1.60 [95% CI, 1.10-2.32] for breakfast and 2.52 [95% CI, 1.04-5.18] for lunch). Skipping dinner, extra meals (snacks) or midnight snacks was not associated with FD. The prevalence of FD in subjects eating 1, 2, and 3 meals per day was 4.8%, 2.2%, and 1.7%, respectively. The frequency of meals was independently inversely associated with prevalence of FD (adjusted ORs were 1 per day: 2.72 [95% CI, 1.19-5.42], and 2 per day: 1.69 [95% CI, 1.16-2.43], P for trend = 0.001).
Conclusions
In the young Japanese people, the frequency of meals may be independently inversely associated with prevalence of FD. In particular, skipping breakfast and/or lunch was associated with the prevalence of FD.

We present a female in her sixties with mixed connective tissue disease who underwent 99mTc-human serum albumin diethylenetriaminepentaacetic acid ( 99mTc-HSA-DTPA) scintigraphy to clarify the cause of generalized edema. Scintigraphy findings directed the diagnosis to protein-losing gastroenteropathy. Various disorders are known to be associated with proteinlosing gastroenteropathy; however, mixed connective tissue disease is a rare cause. 99mTc-HSA-DTPA scintigraphy is helpful in the diagnosis and following the response to therapy of protein-losing gastroenteropathy.

BACKGROUND:
More than 140 million people drink arsenic-contaminated groundwater. It is unknown how much arsenic exposure is necessary to cause neurological impairment. Here, we evaluate the relationship between neurological impairments and the arsenic concentration in drinking water (ACDW).
PARTICIPANTS AND METHODS:
A cross-sectional study design was employed. We performed medical examinations of 1867 residents in seven villages in the Thabaung township in Myanmar. Medical examinations consisted of interviews regarding subjective neurological symptoms and objective neurological examinations of sensory disturbances. For subjective neurological symptoms, we ascertained the presence or absence of defects in smell, vision, taste, and hearing; the feeling of weakness; and chronic numbness or pain. For objective sensory disturbances, we examined defects in pain sensation, vibration sensation, and two-point discrimination. We analyzed the relationship between the subjective symptoms, objective sensory disturbances, and ACDW.
RESULTS:
Residents with ACDW ≥ 10 parts per billion (ppb) had experienced a "feeling of weakness" and "chronic numbness or pain" significantly more often than those with ACDW < 10 ppb. Residents with ACDW ≥ 50 ppb had three types of sensory disturbances significantly more often than those with ACDW < 50 ppb. In children, there was no significant association between symptoms or signs and ACDW.
CONCLUSION
Subjective symptoms, probably due to peripheral neuropathy, occurred at very low ACDW (around 10 ppb). Objective peripheral nerve disturbances of both small and large fibers occurred at low ACDW (> 50 ppb). These data suggest a threshold for the occurrence of peripheral neuropathy due to arsenic exposure, and indicate that the arsenic concentration in drinking water should be less than 10 ppb to ensure human health.
