Objectives Although impulsivity has long been thought as an important factor influencing suicidal behaviors, it is unknown whether impulsivity increases the risk of dying from suicidal behaviors and what specific component among constructs of impulsivity contributes to the risk of dying among suicide attempters. Methods To elucidate the association between impulsivity and medical lethality of suicide attempt among suicide attempters, we consecutively recruited 46 suicide attempters who visited an emergency room of a general hospital located in a metropolitan area, Seoul, Republic of Korea, due to suicide attempts and consented to participate in this study. Then we assessed medical lethality with the Beck Lethality Scale (LS) and impulsivity with the Korean version of the Barratt Impulsiveness Scale-11-Revised (BIS). Demographic variables were obtained from medical records and structured social work reports for suicide attempters. Results Although total scores of the BIS did not correlate with LS scores, only the scores of self-control, that is one of the Barrett's six theoretical constructs of impulsivity in which the higher score indicates less self-control and more impulsivity, had a significant positive correlation with scores of LS (p = 0.003). The association remained significant after adjusting for variables known to affect suicide lethality such as job status, recent alcohol consumption, diagnosis of depressive disorders, and having a plan for suicide (${\beta}=0.429$, p = 0.009). Conclusions Not impulsivity in general, but poor self-control, in particular, predicts lethal suicidal behaviors among suicide attempters. The degree of self-control should be evaluated when assessing patients with elevated suicide risk, and proper measures should be installed to prevent possible future lethal suicide attempts.

The purpose of this presentation is to demonstrate a good results of a second operation, the Waffle procedure, in a patient who did not improve following pericardiectomy. Incomplete parietal pericardiectomy, myocardial fiber atrophy, and unexpected restrictive cardiomyopathy can be considered when the patient\`s symptom does not improve after pericardiectomy is carried out. Constrictive epicarditis is always ruled out. In our case, the patient having constrictive pericarditis combined with pericardial effusion received a pericardiectomy. However, hemodynamics and symptoms of the patient following the operaltion did not improve. However, we experienced a good result following a second operation., the Waffle procedure.

Purpose: Firefighters are vulnerable to burn injury during firefighting. In extensive fires, conducted heat and radiant heat can cause burn injury even though firefighters are not directly exposed to fire. There has been increasing interest in the health problems of firefighters considerably since Hongje-dong fire of 2001, which claimed the lives of six fireman. However, there have been no studies done on the characteristics of firefighter burn injuries in South Korea. Therefore, we investigated the characteristics of firefighter burn injuries in a burn center. Methods: A retrospective, single-center research was performed between Jan 2006 to Dec 2015. 24 firefighters came to the burn center. The electronic medical records of patients were reviewed. Results: Flame burns (87.5%) were the major cause of burn in firefighter. All the patients suffered second-degree or third-degree burns. Mean burn size was 6.1±6.7%. 22 of 24 patients were hospitalized and 2 of 22 hospitalized patients admitted to intensive care unit. Mean length of hospitalization was 29.1±23.7 days and mean length of intensive care unit hospitalization was 6.0±1.4 days. The face was the site most commonly burned, representing 25.8% of injuries. The hand/wrist, upper extremity, and neck were the next largest groups, with 19.4, 12.9, 11.3% of the injuries, respectively. Conclusion: Firefighter burn injuries occur to predictable anatomic sites with common injury patterns. The burn size was small but, admitted patients need about 30 days of hospitalization.

Cavernous lymphangioma is a rare congenital malformation that usually appears in the early childhood. The most common site is head and neck area, where approximately 75% of all lymphangiomas occur. We present a cavernous lymphangioma abutting brachial plexus and causing shoulder pain. A 28-year-old male patient presented with right shoulder pain for 2 months. Neck MRI revealed a lobulated multiseptated cystic mass at the anterior superior aspect of the right neck. Inferior, medial aspect of the mass was abutting brachial plexus. Surgical excision was performed, and pathologic result with immunohistochemical analysis confirmed the diagnosis cavernous lymphangioma.

Purpose : Respiratory syncytial virus (RSV) is one of the main pathogens causing lower respiratory infections (LRI) in young children, usually of limited severity. However, in congenital heart disease (CHD) patients, one of the high-risk groups for RSV infection, RSV can cause serious illnesses and fatal results. To elucidate the effects of RSV infection in CHD patients, we observed RSV infection cases among CHD patients and non-CHD patients. Methods : On admission of 343 LRI patients over 3 years, 77 cases of RSV infection were detected by the RSV antigen rapid test of nasopharyngeal secretion. We compared RSV infection cases among groups of CHD and non-CHD patients. Results : During the winter season, RSV caused 20-0% of LRI admissions in children. In patients with completely repaired simple left to right (L-R) shunt diseases such as ventricular septal defect, atrial septal defect, and patent ductus arteriosus, RSV infections required short admission days similar to non-CHD patients. In patients with repaired CHD other than simple L-R shunt CHD, for whom some significant hemodynamic problems remained, RSV infection required long admission days with severe clinical course. In children with unrepaired CHD, RSV infection mostly occurred in early infant age, with long admission days. RSV infections within a month after cardiac surgery also required long admission days and severe clinical course. Conclusion : To avoid the tragedic outcome of severe RSV infection in the CHD patients, efforts to find the subgroups of CHD patients at high risk to RSV infection are needed, and effective preventive treatment should be applied.

Purpose: The necrotizing fasciitis is a terrifying infectious disease that can rapidly spreads to surrounding tissues when fascia is infected and it can cause sepsis to death if not properly diagnosed and treated. The purpose of this study is to investigate the characteristics, causes, and treatment methods of necrotizing fasciitis in Korea through reviewing patients admitted to our burn center. Methods: 21 patients with necrotizing fasciitis were selected for this study among those inpatients with electronic medical records (EMR) admitted to Hallym University Hangang Sacred Heart Medical Center from Jan 1, 2008 to June 30, 2019. The medical records and wound photos of those 21 selected subjects were reviewed. Results: There were 13 male and 8 female patients and mean age was 58.76 years old. 13 of 21 subjects were survived and 8 died (38% mortality rate). The surgical treatments performed were I&D, fasciotomy, debridement, allograft, burring, STSG, flap, and amputation. The most common causes were burns in 9 subjects (6 contact burns) and cellulitis occurred on skins in 5 subjects. And other various causes were observed as fournier's gangrene, stab wound, intramuscular injection, tumor and bleu toe syndrome (toe necrosis). The infected areas were 11 feet and legs, 7 hips, 3 abdomen and trunk in 21 subjects. Of the 8 deaths, 3 were infected in feet and legs, 2 were infected in hips, and 2 were infected in abdomen and trunk. As for underlying diseases, 12 patients with hypertension or diabetes were the highest and others such as cancer and stroke were found. Conclusion: The only method to increase the survival rate is to 'suspect' the disease as much as possible and perform early extensive excision. It is advisable to treat the disease by the burn center to properly provide adequate and optimal wound management, infection control, medical care and nutritional supports.

Purpose: To find progression and prognosis of pancreatitis developed in massive burn patients through retrospective analysis. Methods: A retrospective study was conducted on 32 patients with abnormal increase of serum lipase level among 2523 acute burn patients admitted to our burn center from January 1, 2017 to June 30, 2018. Pancreatitis in this study was defined as a serum lipase concentration level that is higher than 180 IU/L which is three times more than the normal level (less than 60 IU/L). In this study, a retrospective analysis was performed on patients with serum lipase level higher than 300 IU/L to better understand causality of burns and pancreatitis. Results: 32 patients (1.27%) had serum lipase level higher than 180 IU/L among 2523 acute burn subjects. And 13 patients (0.52%) of these 32 patients had serum lipase level elevated more than 300 IU/L. The study indicated serum lipase level was increased around 7 days after the injury. It returned to normal level early as after 1 to 2 weeks and late as after 4 to 6 weeks of injury. The serum amylase level was increased as similar modality as to the serum lipase level increase. The serum bilirubin, AST, ALT, LD, and GGT were also observed to be elevated when serum lipase was more than 1000 IU/L. Conclusion: The pancreatitis developed in burn patients are mostly as mild symptom. It could due to the ischemic injury and can easily be treated by a temporary fasting, TPN, and Gabexate intravenous injection.

Purpose: The aim of this study was to investigate the characteristics of Acute Kidney Injury Network (AKIN)-defined nephrotoxicity in patients undergoing intravenous colistimethate sodium (CMS) therapy for major burns. Methods: This retrospective study included burn patients who received more than 48 h of intravenous CMS between September 2009 and December 2015. Data collection was performed using the institution's electronic medical record system. Patients assigned to the developed nephrotoxic group experienced aggravation of current AKIN stage during CMS treatment; those assigned to the non-nephrotoxic group experienced no change in current or exhibited improved AKIN stage during CMS therapy. Results: A total of 306 patients were included in this study. All patients were grouped according to AKIN stage: AKIN 0 (n=152); AKIN 1 (n=6); AKIN 2 (n=9); AKIN 3 (n=139). The baseline creatinine (Cr) level was 0.73 mg/dL. The incidence of nephrotoxicity was 50.3% according to AKIN stage; overall mortality was 45.8%. The non-nephrotoxic group consisted of 127 (74.7%) patients and 43 (25.3%) were in the developed nephrotoxic group. In patients requiring continuous renal replacement therapy (CRRT), baseline Cr level was 0.83 mg/dL, pre-CMS Cr level was 1.17 mg/dL, and post-CMS Cr level was 1.34 mg/dL. Conclusion: CMS can be administered without signs of nephrotoxicity for a certain period (approximately 1 week), it can be used relatively safely for 2 weeks. Application of CMS is a reasonable option for treating infections caused by multi-drug resistant gram-negative bacteria in patients with major burns. The caution should be exercised nevertheless.
