Trends in Axillary Surgery for Treating Ductal Carcinoma In Situ: A Korean Population-based Study
신영덕,강길원,장호연,최영진 한국유방암학회 2021 Journal of breast cancer Vol.24 No.1
Purpose: Ductal carcinoma in situ (DCIS) is common in South Korea. We evaluated the patterns of axillary surgery among patients with DCIS to highlight the need for compliance with the updated national guidelines. We also evaluated whether sentinel lymph node biopsy (SLNB) was performed in accordance with the national guidelines. Methods: The Korean Health Insurance Review and Assessment Service-National Inpatient Sample database was searched for patients with DCIS (2009–2015) to identify axillary surgery patterns by breast surgery type, year of diagnosis, age at diagnosis, and the location and volume of surgeries for DCIS at the hospital. The rates of SLNB and axillary dissection were compared using descriptive statistics and univariate analyses. Analyses were also conducted using the chi-squared test and multiple logistic regression analysis. Results: We identified 16,315 Korean women who underwent surgery for DCIS, including 11,292 cases of SLNB (69.2%) and 131 cases of axillary lymph node dissection (0.8%). Breast-conserving surgery (BCS) was performed in 10,323 patients (63.3%) with an SLNB rate of 56.0%, while total mastectomy (TM) was performed in 5,992 patients (36.7%), with an SLNB rate of 92.0%. During 2009–2015, the SLNB rate during TM increased from 88.23% to 92.80%. SLNB was influenced by hospital region and surgical volume, and hospitals performing low volumes of surgeries were significantly more likely to perform SLNB regardless of the surgery type (odds ratio, 1.372; 95% confidence interval, 1.265–1.488). Conclusion: Although the Korean guidelines recommend SLNB for all TM procedures and select BCS procedures for DCIS, relatively high rates of SLNB were performed for BCS, and there was inter-hospital variability in performing SLNB. Improved compliance with the guidelines by the surgeons is critical for Korean patients with DCIS.
Wire-reinforced endotracheal tube fire during tracheostomy -A case report-
신영덕,임승운,배진호,임경훈,심재환,권은정 대한마취통증의학회 2012 Korean Journal of Anesthesiology Vol.63 No.2
Every operation could have a fire emergency, especially in the case of a tracheostomy. When a flammable gas meets a source of heat, the danger of fire is remarkable. A tracheal tube filled with a high concentration of oxygen is also a great risk factor for fire. Intra-tracheal tube fire is a rare, yet critical emergency with catastrophic consequences. Thus, numerous precautions are taken during a tracheostomy like, use of a special tube to prevent laser damage, ballooning of the tube with normal saline instead of air, and dilution of FiO2 with helium or nitrogen. Since the first recorded cases on tube fires, most of the fires were initiated in the balloon and the tip. In the present case report, however, we came across a fire incidence, which originated from the wire.

The literary products of Authors Under the Service of the Army during the Korean War have been neglected on the whole because of the perception that they were little more than war propaganda. The majority of the works (poetry, serial novels, and short stories) Published by these authors in various Army publications such as Junsunmunhak (Literature of the War Front) and Comet, as well as in regular literary periodicals, supports this perception. Most of these works convey simplistic emotions and stereotypes that project untroubled patriotism and strongly antipathetic sentiments against to the Communist North. The appointed leader of this group, Dock-Kyun Choi regarded the pen as another form of weapon to be used against the Communists in the North, and did not shy away from describing in graphic details the atrocities committed by his enemies. But what truly deserves our attention is the fact that many of the same authors who wrote highly propagandistic works also wrote works that can only be described as antiwar. In these works are depicted as faithfully as possible the human sufferings of the war. These works resist and even question the very ideologies that have brought about the conflict, focusing instead on the dark side of the war -the horrifying deaths, the separation of families, and the displacement of people from their homes, How we are to interpret this ambivalence in many of these authors is a task that remains to be carried out. We must approach these works with more seriousness and begin by comparing them with similar products from authors under the service of the Navy and the Air Force during the Korean War.
