Objective: Primary care physicians on remote islands and specialists in mainland are expected to collaborate using telemedicine. This survey aimed to identify diseases for which primary care physicians on remote islands consider telemedicine necessary.Materials and Methods: A mail survey was conducted at rural public clinics on remote islands. Participants were asked to select diseases for which telemedicine with mainland specialists was necessary.Results: A total of 23 physicians participated in this survey. The most common disease category for telemedicine was psychiatric/psychosomatic diseases, followed by neurological and endocrine/nutrition/metabolic diseases.Conclusion: These data may be useful for the future development of telemedicine involving primary care physicians on remote islands and mainland specialists.

A woman in her 60 s presented with chest pain. The electrocardiography showed ST depressed in V3-V6, ST elevation in aVR, and negative T in I, II, aVL, and aVF. Laboratory examination revealed that creatinine kinase isoenzyme-MB and troponin I were elevated. Transthoracic echocardiography revealed moderate aortic regurgitation. Enhanced computed tomography did not show an aortic dissection. Acute coronary syndrome was suspected and cardiac catheterization was done. Aortography showed an intimal flap inside the Valsalva sinus. An emergency operation was performed. Surgical view: the intimal tear affected almost all the circumference of the aorta in the Valsalva sinus and the aortic dissection with a localized and moving intimal flap affected the coronary flow and the aortic dissection caused severe aortic regurgitation and decreased the coronary flow. An aortic root replacement was successfully performed, and the postoperative course was uneventful.

A 25-question “Nationwide Kampo Web Test” was conducted to evaluate the basic knowledge and diagnostic ability of Kampo among medical professionals nationwide. We analyzed the scores of all 608 examinees (241 doctors, 257 pharmacists, 77 others, 12 acupuncturists, 10 nurses, and 11 dentists) and evaluated the test quality. The performance of all examinees was 67.7 ± 16.9 points (mean score ± standard deviation). Among the doctors, the mean score of Kampo medicine specialists (83.8 ± 8.7 points) was significantly higher than that of non-specialists (65.3 ± 16.3 points) (p<0.0001). The performance of doctors who prescribed 20 or more Kampo medicines (78.4 ± 11.5 points) was significantly higher than that of other doctors (p<0.0001). Among the 25 questions, the difficulty levels of 13, 8, and 4 were easy, moderate, and hard (correct answer rates: 70% or more, 40-70%, and less than 40%), respectively. The ability of 13 questions (52%) to distinguish between good and poor performers was extremely high (discrimination index of 0.5 or higher). Collectively, these results supported the good performance of our test, suggesting that it is a highly practical learning achievement evaluation system that could utilize information and communication technology and is expected to be used in future lifelong learning in the field of Kampo medicine.

Purpose: Patients with head and neck cancer (HNC) who undergo dental procedures during radiotherapy (RT) face an increased risk of developing osteoradionecrosis (ORN). Accordingly, new tools must be developed to extract critical information regarding the dose delivered to the teeth and mandible. This article proposes a novel approach for visualizing 3-dimensional planned dose distributions on panoramic reconstruction computed tomography (pCT) images. Materials and Methods: Four patients with HNC who underwent volumetric modulated arc therapy were included. One patient experienced ORN and required the extraction of teeth after RT. In the study approach, the dental arch curve (DAC) was defined using an open-source platform. Subsequently, pCT images and dose distributions were generated based on the new coordinate system. All teeth and mandibles were delineated on both the original CT and pCT images. To evaluate the consistency of dose metrics, the Mann-Whitney U test and Student t-test were employed. Results: A total of 61 teeth and 4 mandibles were evaluated. The correlation coefficient between the 2 methods was 0.999, and no statistically significant difference was observed (P>0.05). This method facilitated a straightforward and intuitive understanding of the delivered dose. In 1 patient, ORN corresponded to the region of the root and the gum receiving a high dosage (approximately 70 Gy). Conclusion The proposed method particularly benefits dentists involved in the management of patients with HNC. It enables the visualization of a 3-dimensional dose distribution in the teeth and mandible on pCT, enhancing the understanding of the dose delivered during RT.

The patient is a 71-year-old man. After receiving chemoradiotherapy (CRTx) for an unresectable esophageal cancer, he developed sudden hematemesis during a follow-up examination. Subsequent imaging via contrast-enhanced computed tomography (CT) showed leakage of the contrast medium from the descending aorta into the esophagus. Consequently, an aortoesophageal fistula (AEF) was diagnosed and an emergency thoracic endovascular aortic stent graft repair (TEVAR) was scheduled. However, during the preparation for surgery, the patient vomited a large amount of blood and went into cardiopulmonary arrest. Following the administration of cardiopulmonary resuscitation, a Sengstaken-Blakemore tube (SB-tube) was inserted intranasally to control bleeding and TEVAR was performed to save his life. Although a gastrostomy was necessary after the surgery, the patient was transferred from the hospital on the 32nd day without any complications. Nonetheless, his general condition deteriorated as the cancer progressed and he died on the 103rd postoperative day. It is generally reported that the risk for esophageal perforation is 10-20% in CRTx for unresectable esophageal cancer. Although issues regarding the long-term prognosis of patients treated with TEVAR have been highlighted in recent years, there have also been reports of life-saving cases following its use; in this case, the patient was discharged home after SB-tube insertion and TEVAR with prompt treatment, resulting in his life being prolonged for an estimated 3 months.

Background/Aims: Immune checkpoint blockade has recently been reported to be effective in treating microsatellite instability (MSI)-high tumors. Therefore, sufficient sampling of histological specimens is necessary in cases of unresectable pancreatic cancer (UR-PC). This multicenter study investigated the efficacy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) using a Franseen needle for MSI evaluation in patients with UR-PC. Methods: A total of 89 patients with UR-PC who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) or EUS-FNB using 22-G needles at three hospitals in Japan (2018–2021) were enrolled. Fifty-six of these patients (FNB 23 and FNA 33) were followed up or evaluated for MSI. Patient characteristics, UR-PC data, and procedural outcomes were compared between patients who underwent EUS-FNB and those who underwent EUS-FNA. Results: No significant difference in terms of sufficient tissue acquisition for histology was observed between patients who underwent EUS-FNB and those who underwent EUS-FNA. MSI evaluation was possible significantly more with tissue samples obtained using EUS-FNB than with tissue samples obtained using EUS-FNA (82.6% [19/23] vs. 45.5% [15/33], respectively; p<0.01). In the multivariate analysis, EUS-FNB was the only significant factor influencing the possibility of MSI evaluation. Conclusions EUS-FNB using a Franseen needle is desirable for ensuring sufficient tissue acquisition for MSI evaluation.

In the 2022 Model Core Curriculum for Medical Education in Japan, "Chapter 3, Educational strategies and assessment" section II. "Learner Assessment," consists of three parts : II-1. Approaches to learner assessment, II-2. Assessment methods, and II-3. Questions about learner assessment. Based on the idea that "the way assessment is done varies from institution to institution," the answer to the "Question" is deliberately not included. We hope that readers will refer to this chapter when planning learning assessments in curriculum development while considering the curriculum's background and context.

Objective: To evaluate the efficacy of fan therapy for the relief of dyspnea in patients with chronic progressive disease. Methods: A systematic electronic database search of all available articles published before October 23, 2019 was conducted using Ichushi-Web of the Japan Medical Abstract Society databases, CENTRAL, EMBASE, and MEDLINE. In addition, a hand-search for updates was performed using PubMed on June 30, 2020 and December 7, 2021. The inclusion criteria were: 1) any RCTs comparing the effect of fan therapy with any other intervention, and 2) patients aged ≥18 years. Exclusion criteria were: 1) duplicate references, and 2) conference presentations. Results: We identified 110 studies, of which 10 met our criteria for inclusion. Finally, five studies were used in the meta-analysis. Fan therapy significantly improved dyspnea in patients with chronic progressive disease compared to control groups with a standardized mean difference of −1.43 (95% confidence interval: −2.70 to −0.17, I2=94%, p<0.0001). Conclusion: Fan therapy was found to be effective in reducing dyspnea in chronic progressive disease.

Background/Aims: Patients with achalasia-related esophageal motility disorders (AEMDs) frequently present with dilated and sigmoid esophagus, anddevelop esophageal diverticulum (ED), although the prevalence and patients characteristics require further elucidation. Methods: We conducted a multicenter cohort study of 3707 patients with AEMDs from 14 facilities in Japan. Esophagography on 3682 patients were analyzed. Results: Straight (n = 2798), sigmoid (n = 684), and advanced sigmoid esophagus (n = 200) were diagnosed. Multivariate analysis revealed that long disease duration, advanced age, obesity, and type I achalasia correlate positively, whereas severe symptoms and integrated relaxation pressure correlate negatively with development of sigmoid esophagus. In contrast, Grade II dilation (3.5-6.0 cm) was the most common (52.9%), while grade III dilation (≥ 6 cm) was rare (5.0%). We found early onset, male, obesity, and type I achalasia correlated positively, while advanced age correlated negatively with esophageal dilation. Dilated and sigmoid esophagus were found mostly in types I and II achalasia, but typically not found in spastic disorders. The prevalence of ED was low (n = 63, 1.7%), and non-dilated esophagus and advanced age correlated with ED development. Patients with right-sided ED (n = 35) had a long disease duration (P = 0.005) with low integrated relaxation pressure values (P = 0.008) compared with patients with left-sided ED (n = 22). Patients with multiple EDs (n = 6) had lower symptom severity than patients with a single ED (P = 0.022). Conclusions The etiologies of dilated esophagus, sigmoid esophagus, and ED are considered multifactorial and different. Early diagnosis and optimal treatment of AEMDs are necessary to prevent these conditions.

Objective: BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers. Methods: We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2 m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively. Results: The average age at diagnosis of OC in gBRCA1m and gBRCA2 m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2 m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2 . The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40. Conclusion There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed.
