The over-the-scope clip (OTSC) system is a powerful full-thickness suturing device used for closing refractory bleeding, perforations, and fistulas in gastrointestinal diseases, offering greater force than conventional clips. Here, we report two cases of pancreatobiliary disease treated using OTSC. The first case involved the successful OTSC ligation of a colonic fistula caused by necrotizing pancreatitis, and the second was a duodenal perforation due to stent migration, which was also successfully treated with OTSC. These cases indicate that OTSC can be beneficial for pancreatobiliary diseases, potentially eliminating the need for surgery when endoscopic treatment is successful.

Background: Acute eosinophilic pneumonia (AEP) is a rare and severe lung condition characterized by a rapid accumulation of eosinophils in the alveoli, leading to respiratory distress. This study analyzed the clinical characteristics of affected patients, aiming to shed light on the relationship between cigarette smoking and AEP. Methods: This retrospective study analyzed 17 cases of AEP, focusing on patients' smoking habits, clinical symptoms, diagnostic findings, and treatment outcomes. Data were collected from medical records, imaging studies, and bronchoalveolar lavage (BAL) findings. Results: The study cohort consisted primarily of male military personnel (94.1%), with a mean age of 20.8 years. Symptoms generally appeared approximately 2.82 days prior to hospitalization, with a mean body temperature at admission of 37.6 °C. The mean initial peripheral blood white blood cell count was 15.3×103/μL, with eosinophil percentages starting at 0.2%, peaking at a mean of 16.1%, and reaching as high as 32.4%. BAL fluid analysis showed a mean eosinophil level of 46.6%±15.1% (range, 17%–67%). In most cases, radiological examinations revealed bilateral ground-glass opacities, interlobular septal thickening, various degrees of airspace consolidation, and bilateral pleural effusions. Steroid treatment was administered to 70.5% of patients, lasting a mean of 8.3 days and resulting in significant improvements. Conclusions These cases reinforce the strong link between cigarette smoking and AEP. Additionally, these cases demonstrate the importance of obtaining a detailed smoking history and thorough diagnostic assessments, including BAL, in order to facilitate a more rapid diagnosis and early initiation of corticosteroid treatment.

Purpose: This study aimed to identify the actor and partner effects of human papillomavirus (HPV) vaccination knowledge, health beliefs, and self-efficacy on parental intentions to vaccinate adolescent sons against HPV. Methods: The participants were 191 couples who met the eligibility criteria. Data were collected from June 2024 through internet communities in Gyeongsangnam Province. The actor-partner interdependence model was used to analyze the parent's actor and partner effects of HPV vaccination knowledge, health beliefs, and self-efficacy on parents' intentions to vaccinate their adolescent sons against HPV. Results: The actor effects of fathers' intentions to vaccinate their adolescent sons against HPV were perceived benefits and self-efficacy; however, the partner effect was not significant. The actor effects of mothers' intentions to vaccinate their adolescent sons against HPV were perceived susceptibility, perceived severity, perceived benefits, and self-efficacy, and the partner effects were fathers' perceived severity and benefits. Conclusion This study indicates that fathers' intentions to vaccinate their adolescent sons against HPV may play an essential role in increasing HPV vaccination rates among adolescent sons.

Conversion therapy is a treatment strategy that shifts from palliative systemic therapy to curative surgical treatment for primary and/or metastatic stage IV gastric cancer (GC).To address its clinical statements, the Korean Gastric Cancer Association aims to present a consensus on conversion therapy among experts attending KINGCA WEEK 2024. The KINGCA Scientific Committee and Development Working Group for Korean Practice Guidelines prepared preformulated topics and 9 clinical statements for conversion therapy.The Delphi method was applied to a panel of 17 experts for consensus and opinions. The final comments were announced after the statement presentation and discussed during the consensus meeting session of KINGCA WEEK 2024. Most experts agreed that conversion herapy provides a survival benefit for selected patients who respond to systemic therapy and undergo R0 resection (88.3%). Patients with limited metastases were considered good candidates (94.2%). The optimal timing was based on the response to systemic therapy (70.6%). The regimen was recommended to be individualized (100%) and the duration to be at least 6 months (88.3%). A minimally invasive approach (82.3%) and D2 lymph node dissection (82.4%) were considered for surgery. However, resection for metastases with a complete clinical response after systemic therapy was not advocated (41.2%). All experts agreed on the need for large-scale randomized-controlled trials for further evidence (100%).Recent advancements in treatment may facilitate radical surgery for patients with stage IV GC. Further evidence is warranted to establish the safety and efficacy of conversion therapy.

Purpose: The purpose of this study was to explore and deeply understand the essential meaning of international students' healthcare management experiences in Korea. Methods: This study applied Colaizzi‘s phenomenological research method to identify the meanings and needs related to health care management experienced by international students during their academic stay in Korea. Data were collected through unstructured interviews, in which open-ended questions were asked to 12 international students. The interviews were conducted from May 10, 2024, to the end of July 2024, followed by an analysis based on Colaizzi’s six-step approach. The criteria set by Lincoln and Guba were used to enhance the reliability and validity of qualitative research. Results: Regarding the meaning of international students' healthcare management experiences in Korea, this study identified four categories, 11 themes, 27 sub-themes, and 108 significant statements. The four categories of international students' health care management experiences were: “neglecting health care management due to unresolved economic difficulties,” “choosing better healthcare management options than those in their home country,” “acquiring a new perspective on healthcare management during their stay in Korea,” and “suggesting directions for improvement and expectations based on their healthcare management experiences in Korea.” This study enabled an understanding of health management practices, with implications for ensuring the successful academic lives of international students. Conclusion This study implies that a deep understanding of international students' healthcare management experiences would contribute to the development of effective health promotion policies and programs for them in the future.

Vertebral arteriovenous fistula (VAVF) is a rare lesion characterized by an abnormal connection between the extracranial vertebral artery and the surrounding venous plexus. It typically arises due to penetrating injury, although it can occasionally result from blunt trauma. Brachial plexus injury (BPI) is also infrequently associated with VAVF. We present a rare case of VAVF caused by blunt trauma, which resulted in BPI. The patient, who had previously sustained a C2 fracture and C2–3 myelopathy from a bicycle accident, presented with new-onset weakness in the right upper extremity. His previous clinical history led to an initial suspicion of either an exacerbation of a pre-existing lesion or a shoulder injury. However, electromyography indicated that the weakness was due to BPI. Further evaluations later revealed VAVF to be the primary cause of the BPI. VAVF must be recognized as a rare potential reason for BPI, as timely intervention is essential for improving patient recovery and prognosis.
