Clinical Endoscopy 2025;58(2):269-277
Background/Aims:
Visualization of palisade vessels (PVs) in Barrett’s esophagus is crucial for proper assessment. This study aimed to determine whether red dichromatic imaging (RDI) improves PV visibility compared with white-light imaging (WLI) and narrow-band imaging (NBI).
Methods:
Five expert and trainee endoscopists evaluated the PV visibility in Barrett’s esophagus using WLI, NBI, and RDI on 66 images from 22 patients. Visibility was rated on a 4-point scale: 4, excellent; 3, good; 2, fair; and 1, poor. The color difference between the most recognizable PV spots and surrounding areas with undetectable blood vessels was also analyzed.
Results:
Mean visibility scores were 2.6±0.7, 2.3±0.6, and 3.4±0.4 for WLI, NBI, and RDI, respectively. The RDI scores were significantly higher than the WLI (p<0.001) and NBI (p<0.001) scores. These differences were recognized by trainees and expert endoscopists. Color differences in PVs were 7.74±4.96 (WLI), 10.43±5.09 (NBI), and 15.1±6.54 (RDI). The difference in RDI was significantly higher than that in WLI (p<0.001) and NBI (p=0.006).
Conclusions
RDI significantly improved PV visibility compared to WLI and NBI based on objective and subjective measures.

The case is a 6-year-0-month-old girl. She was referred to our department at the age of 5 years and 10 months due to persistent fever over 38.0 ℃. Since blood tests and contrast-enhanced computed tomography showed no abnormalities and there was no response to antipyretics, psychogenic fever was suspected, but psychological factors were unclear. She had lived in father’s home country until the age of 4 years and 11 months (father is foreign national/mother is Japanese), had plans to return to father’s home country. Her height was 117.5 cm, weight 18.7 kg, body temperature 37.4 ℃, and her cardiopulmonary findings were normal. She tried five types of Kampo preparations sequentially. Her body temperature less frequently exceeded 38.0 ℃ with kamishoyosan and yokukansan, and never exceeded 38.0 ℃ with kamikihito. Suspecting that family relationships and vague insecurities were behind her symptoms, it was found that she was stressed about plans to return to father’s home country, leading to the diagnosis of psychogenic fever. When investigating the etiology behind the symptoms, it is useful to refer to the responsiveness to Kampo medicines.

We use transumbilical laparoscopic-assisted appendectomy (TULAA) with a lifting retractor as the surgical technique of first choice for acute appendicitis. Although this technique provides excellent cosmetic results and contributes to reducing medical costs, it is less advantageous in difficult-to-complete cases that require conversion to pneumoperitoneum or additional ports. We retrospectively reviewed the records of 76 patients who underwent laparoscopic appendectomy between June 2020 and March 2023 (43 in a TULAA group and 33 in a pneumoperitoneal conversion group) to identify preoperative factors associated with pneumoperitoneal conversion. Univariate analysis showed significant differences for preoperative C-reactive protein (CRP) level, age, and body mass index. Logistic regression analysis identified preoperative CRP level and age as significant risk factors for pneumoperitoneal conversion. The pneumoperitoneal conversion rate was 12.5%, 48.2%, and 68% for patients with 0, 1, and 2 preoperative risk factors, respectively, indicating patients with 2 risk factors were more likely to undergo pneumoperitoneal conversion. These data may inform the selection of the surgical technique and the decision to convert to pneumoperitoneum.

A 50-year-old man with a history of coronary artery bypass grafting (CABG) 5 years prior to presentation underwent MitraClip placement for severe mitral regurgitation. Subsequently, he underwent on-pump beating heart endoscopic minimally invasive cardiac surgery (MICS) for mitral valve replacement for acute heart failure secondary to single leaflet device attachment. Endoscopic MICS via a right small thoracotomy approach is useful for reoperation after CABG in patients with a high risk of graft injury. Beating-heart surgery may be an effective option to avoid the risks associated with prolonged cardiac arrest time in patients with low left ventricular function.

Advances in information and communication technology (ICT)-especially, the spread of social networking services (SNSs)-have facilitated the dissemination of information and an explosion of health information lacking scientific evidence. Therefore, we believe that community pharmacies are the most suitable bases for distributing health information. In 2019, we launched the health support pharmacy “Toyonaka Model” in collaboration with the pharmaceutical association, municipal government, and university. Touch-panel digital signage (DS) was used for real-time distribution of ever-changing information and a rapid grasp of pharmacy users’ responses to various types of information. Between September 2019 and August 2021, one DS was installed in a pharmacy in each of Toyonaka City’s seven areas along with 14 questions on the usefulness of the delivered information. Respondents answered the 14 questions by a tablet or questionnaire; touch logs for DS were collected. When a pharmacy user consulted with a pharmacist about information delivered via DS, the contents were recorded and described by the pharmacist on a 4-point scale (e.g., “inquiry only,” “went through to execution”). From the 850 completed questionnaires and 61,565 touches, 88.7% of the respondents indicated that the information was useful, and 90.0% expressed interest in receiving more health information in the future. Thus, health information provided by DS may be useful to pharmacy users, as demonstrated by 113 cases in which the pharmacist was consulted regarding such information. In 62 of these cases, there were indications that the DS information might have influenced users’ behavior and intended actions.

We began providing comprehensive cardiac rehabilitation for congestive heart failure (CHF) in 2014 at our institution, using an original pamphlet and heart failure notebook to provide life guidance for CHF. However, the life guidance rate was lower in 2017 (61%) than it was in 2014 (77%). The objective of this study was to investigate the awareness of life guidance among nurses. We administered a questionnaire survey regarding life guidance to 28 nurses in December 2018. Among the 27 respondents, 26 nurses (96%) had high motivation and 21 (80%) felt a sense of accomplishment. Responses to the “most important point in life guidance” were “understanding living condition” by 14 nurses, “heart failure notebook” by 9 nurses, and “guidance using the pamphlet” by 6 nurses. Fifteen nurses (58%) felt that the guidance had become routine in nature, and 5 nurses (19%) were worried about their instruction. The nurses were motivated to provide life guidance, but they also felt that the guidance had become routine because they had been providing the same guidance for many years. We consider that the factors related to the lower life guidance rate are the routine/repetitive nature of the guidance and concerns about instruction. Going forward, we need to review the content of the guidance and the teaching approach.

Clinical Psychopharmacology and Neuroscience 2020;18(4):599-606
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.

Persistent sciatic artery (PSA) is a rare congenital vascular anomaly with an incidence ranging from 0.025 to 0.06% of the general population. We report a 65-year-old male patient with bilateral PSA suffering from intermittent right-calf claudication. Peripheral pulsations could be palpated well at the right common femoral artery but not at the right popliteal artery. His ankle brachial index (ABI) was 0.79 on the right and 0.99 on the left. Computed tomographic (CT) angiography demonstrated that the bilateral PSAs were branched from the internal iliac arteries and the right PSA was completely occluded, whereas aneurysmal change was not evident. Both superficial femoral arteries were incompletely developed. Blood flow to the peroneal artery, anterior and posterior tibial arteries were maintained in both lower legs via a network of collateral arteries. Arterial bypass from right common femoral artery to the above-knee popliteal artery using knitted Dacron graft was performed and postoperative ABI of the right lower limb improved to 1.06. Ten months after the intervention, the patient was then suffered from intermittent left-calf claudication caused by complete occlusion of left PSA, therefore, above-knee femoropopliteal arterial bypass using knitted Dacron graft was performed. PSA is often asymptomatic until a complication develops and the careful monitoring to prevent the risk of thromboembolic and aneurysmal events are recommended.
