Pulmonary carcinosarcoma(Sarcomatoid carcinoma of the lung) is a rare pulmonary malignancy, which is defined as having an admixtture of both carcinomatous and sarcomatous components. Pulmonary carcinosarcoma occurs most frequentlly in males between 50 and 80 years of age. It predominantly affects the upper lobe and/or the principal bronchi, and is associated with a history of smoking. Here, we report a case of pulmonary carcinosarcoma with a left lobe atelectasis due to an endobronchial mass in a 56-year-old male. After a left pneumonectomy, the pathologic stage was IIb (T3N0M0). Four months later, an abdominal mass was observed and exploratory laparotomy revealed metastases of the pulmonary carcinosarcoma to the pelvic cavity.

Purpose: This study was conducted to examine the role of video education on cancer patient advance directive writing. Methods: To evaluate the effects of video education on cancer patient advance directive knowledge, attitude, writing intention and writing, this study employed a non-equivalent control group and non-synchronized design as a quasi-experimental study. The target population of this study were adults aged ≥50 years old, diagnosed with cancer in South Korea. The proximity population were also cancer patients who visited a university hospital. The control group (n=31) were educated verbally using a leaflet and the experimental group (n=30) were educated by a video program developed by the National Bioethics Policy Institute for 10 minutes, supplemented with a leaflet. The advance directives video program form provided by the Korean Ministry of Health and Welfare was used. Results: The experimental group showed a positive change in knowledge level (F=52.82, p<.001, effect size=0.96), attitude (F=12.21, p<.001, effect size=0.46), the intention to write (F=18.22, p<.001, effect size=0.56) advance directives and a higher proportion of writing (χ2=13.87, p<.001) than the control group. Conclusion The results of this research show that providing information through video is a more effective educational medium for retention of knowledge, attitude, writing intention, and writing of cancer patient's advance directives.

Purpose: This study was conducted to gain a comprehensive and in-depth understanding of infection control nurses’ burnout experiences in hospitals during the COVID-19 pandemic. Methods: We recruited 11 infection control nurses (ICNs) who worked in hospitals in Korea through purposive sampling. Data collected through one-to-one, in-depth interviews were transcribed and analyzed using qualitative content analysis. Results: Infection control nurses’ burnout experiences were categorized into five themes and 11 sub-themes. The themes were as follows: “challenges faced while playing a pivotal role in infectious disease management,” “conflict of interest prevalent inside and outside,” “physical and mental collapse,” “a long road to achieving stability in the infection control unit,” and “source of strength to endure.” Conclusion In light of the need to better prepare for future outbreaks of emerging infectious diseases, such as COVID-19, the findings of this study highlight the need for strategic approaches, such as developing programs to provide psychological and social support for infection control nurses, as well as establishing a well-designed system of nursing care for infectious diseases to alleviate their burnout.

PURPOSE: To evaluate the clinicopathological characteristics and prognosis of localized resectable genitourinary sarcomas in adults. MATERIALS AND METHODS: Between September, 1996 and November, 2008, 18 consecutive cases of adults (12 men and 6 women; median age 48.8 years) who were treated for primary genitourinary sarcomas were identified. The following variables were analyzed: patient age, gender, body mass index, American Society of Anesthesiologists (ASA) score, primary organ, tumor histology, size, necrosis, Federation Nationale des Centres de Lutte Contre le Cancer (FNCLCC) grade, and surgical margin positivity. Recurrence-free survival and disease-specific survival were the study end-points. RESULTS: The most common presenting symptom was a palpable mass (six cases, 33.3%), the most common site was the kidney (six cases, 33.3%), and the most common histological subtype was leiomyosarcoma (eight patients, 44.4%). Complete resection with negative surgical margins was achieved in 13 patients (72.2%). The median follow-up period was 49.9 months (range 6.4 to 147.6). The recurrence-free survival rates at 1, 3, and 5 years were 81.6%, 66.5%, and 66.5%, respectively. Recurrence-free survival only associated significantly with ASA score (p=0.018). The disease-specific survival rate at 1, 3, and 5 years was 88.9%, 76.2%, and 67.7%, respectively. Disease-specific survival was associated significantly only with FNCLCC grade (p=0.042). CONCLUSION: Although genitourinary sarcomas in adults are a rare group of tumors with a poor prognosis, some patients may have a favorable prognosis. Our findings suggest that FNCLCC grade is the most important prognostic factor for these patients.

BACKGROUNDS/AIMS: The aim of this study is to clarify the safety and feasibility of laparoscopic hepatectomy, through comparing the early and late periods of perioperative outcomes. METHODS: We retrospectively analyzed 138 patients who underwent laparoscopic hepatectomy from January 2003 to June 2011, at Yeungnam University Hospital. We divided the total patients to early period (from January 2003 to February 2007, n=49) and late period (from March 2007 to June 2011, n=89) groups and compared the perioperative outcomes including the mean operation time, intra-operative blood loss, postoperative hospital stay, intensive care unit (ICU) stay, and duration of liver function test (LFT) normalization. RESULTS: The mean operation time was 308 minutes (range: 140-510) in the early group and 193 minutes (range: 40-350) in the late period group (p<0.001). The mean intraoperative blood loss was 171 ml (range: 50-1,200) in the early and 44 ml (range: 0-400) in the late group (p=0.005). The postoperative hospital stay was 9.7 days (range: 4-31) in the early and 6.8 days (range: 2-9) in the late period (p<0.001). The ICU stay hour was 21.6 hours (range: 0-120) in the early and 2.8 hour (range: 0-24) in the late period (p<0.001). The duration of LFT normalization was 5.7 days (range: 0-39) in the early and 2.1 days (range: 0-20) in the late period (p=0.003). The perioperative outcomes in the late period were better than the early period, which showed a statistically significant difference. CONCLUSIONS: Laparoscopic hepatectomy is feasible and can be safely performed in selected patients but requires a long experience in open liver resection and mastery of laparoscopic surgical skills.
