OBJECTIVE: This study presents a preliminary report on the chest radiographic and computed tomography (CT) findings of the 2019 novel coronavirus disease (COVID-19) pneumonia in Korea.MATERIALS AND METHODS: As part of a multi-institutional collaboration coordinated by the Korean Society of Thoracic Radiology, we collected nine patients with COVID-19 infections who had undergone chest radiography and CT scans. We analyzed the radiographic and CT findings of COVID-19 pneumonia at baseline. Fisher's exact test was used to compare CT findings depending on the shape of pulmonary lesions.RESULTS: Three of the nine patients (33.3%) had parenchymal abnormalities detected by chest radiography, and most of the abnormalities were peripheral consolidations. Chest CT images showed bilateral involvement in eight of the nine patients, and a unilobar reversed halo sign in the other patient. In total, 77 pulmonary lesions were found, including patchy lesions (39%), large confluent lesions (13%), and small nodular lesions (48%). The peripheral and posterior lung fields were involved in 78% and 67% of the lesions, respectively. The lesions were typically ill-defined and were composed of mixed ground-glass opacities and consolidation or pure ground-glass opacities. Patchy to confluent lesions were primarily distributed in the lower lobes (p = 0.040) and along the pleura (p < 0.001), whereas nodular lesions were primarily distributed along the bronchovascular bundles (p = 0.006).CONCLUSION: COVID-19 pneumonia in Korea primarily manifested as pure to mixed ground-glass opacities with a patchy to confluent or nodular shape in the bilateral peripheral posterior lungs. A considerable proportion of patients with COVID-19 pneumonia had normal chest radiographs.

OBJECTIVE: The causal association of human papillomavirus (HPV) in uterine cervical cancer was well established and this oncogenic virus was reported to be a biomarker for overall recurrence and central pelvic recurrence. The objective of the present systematic review and meta-analysis was to assess the role of HPV DNA testing in early detection of recurrence among cervical cancer survivors after radiotherapy.METHODS: We performed a systematic review and meta-analysis by means of searching electronic databases for published articles between January 1984 and June 2018, on the basis of standard systematic review guidelines prescribed by major agencies namely Cochrane Collaboration (https://www.cochrane.org) and Campbell Collaboration (https://www.campbellcollaboration.org). The meta-analysis component was further modified appropriately for the synthesis of sensitivity and specificity results.RESULTS: A total of 1,055 cervical cancer cases who had received pelvic radiation with or without chemotherapy from ten cohort studies were evaluated. The overall pooled sensitivity and specificity of HPV DNA testing was 0.84 (95% confidence interval [CI]= 0.66–0.94) and 0.35 (95% CI=0.20–0.54) respectively. The positive likelihood ratio was 1.3 (95% CI=1.0–1.7) and the negative likelihood ratio was 0.45 (95% CI=0.18–1.10) with an estimated diagnostic odds ratio of 3 (95% CI=1–9).CONCLUSION: The screening for HPV DNA testing during follow-up facilitates early detection of recurrence after radiotherapy.

The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient's developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients' knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients' adherence to therapy, maintain the appropriate health status, improve patients' self-management, and promote self-reliance among patients.

PURPOSE: The aim of this study was to examine degrees of nurse-nurse collaboration and nurse-physician collaboration, and investigate their relationships to the occurrence of medical errors. METHODS: A cross-sectional questionnaire survey was conducted with 264 nurses in a university hospital. The questionnaire included fivecomponent nurse-nurse collaboration and three-component nurse-physician collaboration scales. Data were analyzed using independent t-tests, ANOVA, χ2 tests, and multiple logistic regression. RESULTS: Mean score for nurse-nurse collaboration was 2.8 out of 4.0, and for nurse-physician collaboration, 3.4 out of 5.0. There were significant differences in the nurse-nurse and nurse-physician collaboration scores by nurses' preference to workplace and work unit. A significant difference was found in the nurse-nurse collaboration scores by job position. Fifty-seven (21.60%) nurses responded that they had experienced a medical error in the last six months. Logistic regression analysis revealed that nurse-physician collaboration was a significant factor associated with nurses' error experience. Nurses with higher scores for the nurse-physician relationship component were less likely to experience medical errors. CONCLUSION: Findings from this study show that nurse-nurse and nurse-physician collaboration were moderate. Negative relationship between nurse-physician collaboration and the occurrence of medical error indicates that enhancing nurse-physician collaboration would contribute to improving patient safety.

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract with an unknown etiology and pathogenesis. The incidence and prevalence of IBD are increasing rapidly in Korea. Approximately one-third of patients with IBD appear to develop extra-intestinal manifestations with the skin being one of the most commonly affected organs. They may precede, occur simultaneously, or follow the diagnosis of IBD. In addition, they may parallel with the luminal symptoms or independent from the disease activity of IBD. This review outlines the skin manifestations associated with IBD and discusses their management. Skin manifestations should be managed in close collaboration with a dermatologist.

Dysplasia is a precancerous lesion of colorectal cancer in patients with long-standing inflammatory bowel diseases (IBDs), such as ulcerative colitis and Crohn's disease. Recent guidelines suggest endoscopic resection as a key modality for the treatment of endoscopically resectable dysplasia in patients with colitis. Endoscopic submucosal dissection (ESD) has been suggested as one of the therapeutic options for dysplasia that is potentially resectable but not suitable for the conventional endoscopic mucosal resection technique. Several recent studies supported the feasibility of ESD for the treatment of colitis-associated dysplasia in terms of the en bloc and complete resection rates and the risk of procedure-related complications. However, these studies were performed exclusively in expert centers. Moreover, the local and metachronous recurrence rates were relatively high, and long-term outcome data are still lacking. Endoscopists should be highly skilled in colorectal ESD and have an intensive understanding of not only the lesions but also the conditions of patients with IBDs. Therefore, the decision to perform ESD for colitis-associated dysplasia should be made scrupulously after careful discussion with patients, in collaboration with a multidisciplinary IBD team including physicians, surgeons, and pathologists specialized in IBDs.

Capsule endoscopy (CE) is a preferred diagnostic method for analyzing small bowel diseases. However, capsule endoscopes capture a sparse number of images because of their mechanical limitations. Post-procedural management using computational methods can enhance image quality. Additional information, including depth, can be obtained by using recently developed computer vision techniques. It is possible to measure the size of lesions and track the trajectory of capsule endoscopes using the computer vision technology, without requiring additional equipment. Moreover, the computational analysis of CE images can help detect lesions more accurately within a shorter time. Newly introduced deep leaning-based methods have shown more remarkable results over traditional computerized approaches. A large-scale standard dataset should be prepared to develop an optimal algorithms for improving the diagnostic yield of CE. The close collaboration between information technology and medical professionals is needed.
