Background: The prevalence of scabies, a contagious parasitic skin disease, has decreased to ＜1% in South Korea.However, an increase in the elderly population has led to occasional outbreaks. This study aimed to analyze the epidemiological changes and clinical features of scabies diagnosed in Ulsan over the past decade. Objective: This study aimed to analyze the epidemiological changes and clinical features of scabies infections diagnosed at a tertiary hospital in Ulsan over the past decade. Methods: We conducted a retrospective study at Ulsan University Hospital that reviewed 235 cases from 2013 to 2022.We analyzed the medical records of patients diagnosed with scabies by dermoscopy and microscopic examination. Results: Among 55,430 patients, 235 were confirmed to have scabies, with an overall prevalence of 0.42%. The highest annual incidence was in 2018 (35 cases), with a subsequent decrease but a gradual increase from 2019 to 2022. The most common infection route was through nursing facilities (32.3%). The elderly (≥70 years) comprised 32.3% cases, and typical clinical manifestations were papules (80.4%) of the trunk and extremities. Eosinophilia was observed in 31.4% inpatients. The mean treatment duration was 29.15 days. Conclusion We report a declining but significant prevalence of scabies in Ulsan, with many cases occurring among the elderly in nursing facilities. This study underscores the need for continued surveillance and education regarding the diagnosis and management of scabies in healthcare and community facilities.

Objective: To survey experts’ opinions in abdominal radiology (radiologists) and pancreas-specialized gastroenterology (pancreatologists) in South Korea regarding diagnosing and managing pancreatic cystic neoplasms (PCNs). Materials and Methods: Between August 25, 2023, and October 5, 2023, an online survey was conducted among members of the Korean Society of Abdominal Radiology and the Korean Pancreatobiliary Association via email invitation. Results: The responses from 100 radiologists and 41 pancreatologists were analyzed. Of the respondents, 55.3% (78/141) reported seeing more than 50 patients or reading more than 50 exams related to PCN each month. The most common and preferred diagnostic modality for PCN was contrast-enhanced computed tomography (CECT), favored by 87.8% (36/41) of pancreatologists. When discrepancies arose between CECT or magnetic resonance imaging (MRI) and endoscopic ultrasound, 31.2% (44/141) of the respondents opted for multidisciplinary team discussion, whereas 29.1% (41/141) chose short-term follow-up using CECT or MRI. A total of 88.7% (125/141) of the respondents adhered to the 2017 International Association of Pancreatology (IAP) guidelines in their practice. Among the radiologists, 51.0% (51/100) endorsed a cut-off value of 5 mm for enhancing mural nodules, and 22.0% (22/100) supported a 5 mm/2 yr growth rate in the IAP guidelines v.2017.Additionally, 73.0% (73/100) of radiologists favored discontinuing surveillance, whereas 41.5% (17/41) of pancreatologists disagreed with stopping surveillance. Conclusion The survey underscores the clinical burden PCN poses and identifies CECT as the foremost diagnostic tool.Variability was noted in the terminology, differential diagnosis, approaches for resolving discrepancies between imaging examinations, and opinions on surveillance discontinuation among the respondents as a whole, as well as between radiologists and pancreatologists. Although the 2017 IAP guidelines are primarily followed, there remains a level of dissatisfaction with risk stratification among radiologists. This highlights the need for more standardized diagnostic algorithms and improved consensus among specialists to address these challenges.

Background/Aims: The optimal duration and interval of follow-up for cystic lesions of the pancreas (CLPs) is not well established. This study was performed to investigate the optimal duration and interval of follow-up for CLPs in clinical practice. Methods: Patients with CLPs without worrisome features or high-risk stigmata underwent followup with computed tomography at 6, 12, 18, and 24 months and then every 12 months thereafter. A retrospective analysis of prospectively collected data was performed. Results: A total of 227 patients with CLPs detected from 2000 to 2008 (mean initial diameter, 1.3±0.6 cm) underwent follow-up for a median of 120 months. Twenty-two patients (9.7%) underwent surgery after a median of 47.5 months. Malignancies developed in four patients (1.8%), one within 5 years and three within 10 years. One hundred and fourteen patients (50.2%) were followed up for more than 10 years. No malignancy developed after 10 years of follow-up. During surveillance, 37 patients (16.3%) experienced progression to surgical indication. In patients with CLPs less than 2 cm in diameter, development of surgical indications did not occur within 24 months of follow-up. Conclusions CLPs should be continuously monitored after 5 years because of the persistent potential for malignant transformation of CLPs. An interval of 24 months for initial follow-up might be enough for CLPs with initial size of less than 2 cm in clinical practice.
