BACKGROUND: Descending necrotizing mediastinitis (DNM) is a serious disease originating in odontogenic or oropharyngeal infection with high mortality despite adequate antibiotics and aggressive surgery. We analyzed results of treatment for DNM. MATERIAL AND METHOD: We studied 8 cases diagnosed as DNM from 1998 to 2007. All patients received emergent surgical drainage and debridement with broad spectrum antibiotics just after diagnosis. Antibiotics were changed after bacterial susceptibility testing. The surgical approach included 2 cases of cervicotomy, 6 cases of cervicotomy, and a thoracotomy. RESULT: The interval between symptom onset and hospitalization was 4.6+/-1.8 days (1~9 day). DNM originated in 4 cases of odontogenic infection (50%), 2 cases of oropharyngeal infection (25%), and 2 cases of unknown origin (25%). Causative organisms were found in 6 cases; Streptococcus in 4 cases, Staphylococcus in 1 case, and Klebsiella in 1 case. The Endo DNM classification was type I (2 cases), IIA (3 cases), and IIB (3 cases). The incidence of thoracotomy was 75%. The surgical mortality rate was 25% (2/8). The cause of death was multiple organ failure caused by septic shock. All mortality cases received only cervicotomy and aggravated infections after initial drainage. CONCLUSION: Early diagnosis, immediate surgical drainage, and adequate antibiotics, including covered anaerobes, are required. Thoracotomy should be performed with cervicotomy even for localized DNM.

BACKGROUND: Recently, percutaneous cardiopulmonary support (PCPS) has been widely used to rescue patients in cardiogenic shock or cardiac arrest. However, patients with cardiopulmonary bypass (CPB) weaning failure during open heart surgery still have very poor outcomes after PCPS. We investigated clinical results and prognostic factors for patients who underwent PCPS during open heart surgery. MATERIAL AND METHOD: From January 2005 to December 2008, 10 patients with CPB weaning failure during open heart surgery underwent PCPS using the CAPIOX emergency bypass system (EBS(R), Terumo Inc, Tokyo, Japan). We retrospectively reviewed the medical records of those 10 patients. RESULT: The average age of the patients was 60.2+/-16.5 years (range, 19~77 years). The mean supporting time was 48.7+/-64.7 hours (range, 4~210 hours). Of the 10 patients, 6 (60%) were successfully weaned from the PCPS While 5 (50%) were able to be discharged from the hospital. Complications were noted in 5 patients (50%). In univariate analysis, long aortic cross clamp time during surgery, mediastinal bleeding during PCPS and high level of Troponin-I before PCPS were significant risk factors. All of the discharged patients are still surviving 34+/-8.6 months (range, 23~48 months) post-operatively. CONCLUSION: The use of PCPS for CPB weaning failure during open heart surgery can improve the prognosis. More experience and additional clinical studies are necessary to improve survival and decrease complications.

The most common primary heart tumor in infants is the rhabdomyoma.It is known that tuberous sclerosis is found in half of the patients with cardiac rhabdomyoma. Because the prognosis of this tumor associated with subaortic stenosis is poor,the surgical intervention is indicated.We report one case of left ventricular rhabdomyoma with tuberous sclerosis.

Systemic infection with Aspergillus is an opportunistic disease that affects mainly immunocompromised hosts, and is associated with a high mortality rate. It typically occurs in patients with several predisposing factors, but Aspergillus endocarditis of native valves is rare and experience in diagnosis and treatment is limited. We report a case of native valve endocarditis caused by Aspergillus. A 35-yr-old male patient who underwent pericardiocentesis four months previously for pericardial effusion of unknown etiology presented with right leg pain and absence of the right femoral artery pulse. Cardiac echocardiography revealed severe mitral insufficiency with large mobile vegetations, and computed tomographic angiography showed embolic occlusion of both common iliac arteries. We performed mitral valve replacement and thromoembolectomy, and Aspergillus was identified as the vegetation. We started intravenous amphotericin B and oral itraconazole, but systemic complications developed including superior mesenteric artery aneurysm and gastrointestinal bleeding. After aggressive management, the patient was discharged 78 days post surgery on oral itraconazole. He was well at 12 months post discharge but died in a traffic accident 13 months after discharge.

BACKGROUND: In order to develop the acute heart failure model for the animal experiment of the pneumatic ventricular assist device, we decided to use young pig whose coronary artery distribution is almost the same as humans and also very cheap in price. The purpose of this study is to develop stable, reproducible acute ischemic heart failure model in swine using coronary artery ligation method. MATERIAL AND METHOD: Five young pigs whose weights are the same as adult humans are under experiment. Each pig was under endotracheal intubation and connected to a mechanical ventilator. Through left lateral thoracotomy, we exposed the heart and induced ischemic heart failure by coronary artery ligation. The ligation began at the distal part of the left anterior descending coronary artery. After 5 minutes of initial ligation we reperfused the artery and then re-ligated. Before and after each ligation-reperfusion procedure we assessed the left ventricular end-diastolic pressure, arterial pressure, and cardiac index. We also measured left ventricular end-diastolic dimension, end-systolic dimension, fractional shortening, ejection fraction using intraoperative epicardial echocardiography. After appropriate heart failure was established with sequential (from distal part of LAD to proximal location) ligation-reperfusion-ligation procedure, we inserted the ventricular assist device and operated. RESULT: We established stable acute ischemic heart failure in 3 of 5 young pigs with this sequential ligation-reperfusion-ligation procedure, and could maintained 50% less ejection fraction before the procedure according to intraoperative epicardial echocardiography. We also observed no ventricular arrhythmia usually associated with simple coronary artery ligation in large animals and no cardiac arrest associated with ventricular arrhythmia or myocardial stunning. In pathologic specimen, we observed scattered ischemic myocardium in all around the ischemic field induced by coronary artery ligation. CONCLUSION: Under the concept of ischemic preconditioning, we developed safe and reproducible acute ischemic heart failure model in swine using sequential coronary artery ligation-reperfusion-ligation method.

A 32 year-old man was transferred to our hospital due to blood-tinged sputum for 15 days. He had been treated at a private hospital for recurrent pneumonia. The chest X-ray showed an atelectasis on the right middle lobe. Computed tomography of the chest demonstrated a broncholith on right middle lobar bronchus with lobar atelectasis of the right middle lobe. We tried to remove the broncholith through fiberoptic bronchoscopy, but could not remove it. Therefore, we performed surgical removal of broncholith and the right middle lobectomy. The cause of broncholith was identified as actinomycosis by pathologic examination. The broncholith caused by actinomycosis is rare. We report a rare case of broncholithiasis with recurrent obstructive pneumonia caused by actinomycosis, which was treated by surgical operation.

BACKGROUND: The purpose of the study was to estimate the mental health problems and other related factors in residents that experienced the Samsung-Hebei spirits oil spill by surveying PTSD symptoms. METHOD: Trained interviewers performed direct interviews of the residents approximately 70 days after the oil spill. We investigated PTSD symptoms through PTSD Symptom Scale Interview Version (PSS-I). To determine those factors related to PTSD symptoms, the following factors were determined as part of the survey: gender, age, occupation, duration of cleanup activity, monthly income and amount of debt. Logistic regression analysis was used to analyze all factors. RESULTS: Of the 318 residents investigated, 56.6% of the subjects had PTSD symptoms related to the spirits oil spill (about 70 days post spill). With regard to occupation, those subjects answering fishery (POR:3.05) and commerce (POR:4.24) as their occupations experienced higher PTSD symptoms than residents answering farming as their occupation. Residents who answered that they had debt over 10 million KRW (POR:2.61) were more vulnerable to PTSD symptoms compared to residents without debt; residents with acute physical symptoms were vulnerable (POR:5.11) to PTSD symptom compared to residents without acute physical symptoms. The results of multiple logistic analysis, including the cleanup activity, age, gender, occupation, acute physical symptoms and amount of debt in the model suggest that only cleanup activity increased PTSD symptoms. The subjects who had engaged in cleanup activities for longer periods of time had more PTSD symptoms and an additional dose-response relationship. CONCLUSION: Many residents in Samsung-Hebei spirits oil spill area had PTSD symptoms. This suggests that there were serious mental health problems among the residents, who might require specific social supports and psychiatric interventions as a result of the oil spill.

BACKGROUND: Percutaneous cardiopulmonary support (PCPS) has the potential to rescue patients in cardiogenic shock who might otherwise die. PCPS has been a therapeutic option in a variety of the clinical settings such as for patients with myocardial infarction, high-risk coronary intervention and postcardiotomy cardiogenic shock, and the PCPS device is easy to install. We report our early experience with PCPS as a life saving procedure in cardiogenic shock patients due to acute myocardial infarction. MATERIAL AND METHOD: From January 2005 to December 2006, eight patients in cardiogenic shock with acute myocardial infarction underwent PCPS using the CAPIOX emergency bypass system (EBS(R), Terumo, Tokyo, Japan). Uptake cannulae were inserted deep into the femoral vein up to the right atrium and return cannulae were inserted into the femoral artery with Seldinger techniques using 20 and 16-French cannulae, respectively. Simultaneously, autopriming was performed at the EBS(R) circuit. The EBS? flow rate was maintained between 2.5~3.0 L/min/m2 and anticoagulation was performed using intravenous heparin with an ACT level above 200 seconds. RESULT: The mean age of patients was 61.1+/-14.2 years (range, 39 to 77 years). Three patients were under control of the EBS? before percutaneous coronary intervention (PCI), three patients were under control of the EBS? during PCI, one patient was under control of the EBS after PCI, and one patient was under control of the EBS(R) after coronary bypass surgery. The mean support time was 47.5+/-27.9 hours (range, 8 to 76 hours). Five patients (62.5%) could be weaned from the EBS(R) after 53.6+/-27.2 hours (range, 12 to 68 hours) of support. All of the patients who could successfully be weaned from support were discharged from the hospital. There were three complications: one case of gastrointestinal bleeding and two cases of acute renal failure. Two of the three mortality cases were under cardiac arrest before EBS(R) support, and one patient had an intractable ventricular arrhythmia during the support. All of the discharged patients are still surviving at 16.8+/-3.1 months (range, 12 to 20 months) of follow-up. CONCLUSION: The use of EBS(R) for cardiogenic shock caused by an acute myocardial infarction could rescue patients who might otherwise have died. Successfully recovered patients after EBS(R) treatment have survived without severe complications. More experience and additional clinical investigations are necessary to elucidate the proper installation timing and management protocol of the EBS? in the future.

OBJECTIVE: Korea has 3,170 islands with about 188,000 inhabitants. These inhabitants' needs for health services might go unmet because of geographic isolation, slimmer availability of health services, and higher proportion of the elderly compared with the mainland population. Unmet health service needs might result in serious health problems for these island residents. Therefore, the purpose of this study was to investigate their unmet health service needs and related factors from population of Nowha island. METHODS: The survey was conducted from July 30 to August 1 by trained interviewers. Target population were residents in Nohwa island and the sampling method was incomplete quota sampling. General characteristics, socioeconomic status, utilization of health service, and unmet medical service needs were investigated. First univariate and then multivariate logistic analyses were done for the statistical analysis. RESULTS: 324 residents were surveyed and the proportion of unmet health services needs was 26.5%. People living alone and of female sex had increased health services needs based on univariable analysis. From the multivariate analysis, those living alone increased the health services needs. Self-determined low socioeconomic status and medical aid increased the proportion of unmet medical needs, but these were not statistically significant. CONCLUSION: In Nowha island, those who are elder, and of lower socioeconomic status had much higher unmet medical needs. The results suggest the need for more social support by qualified health services to solve this unmet medical needs problem.

The GlideScope® videolaryngoscope (GVL) is widely used in patients with difficult airways and provides a good glottic view. However, the acute angle of the blade can make insertion and advancement of an endotracheal tube (ETT) more difficult than direct laryngoscopy, and the use of a stylet is recommended. This randomized controlled trial compared Parker Flex-It™ stylet (PFS) with GlideRite® rigid stylet (GRS) to facilitate intubation with the GVL in simulated difficult intubations. Methods: Fifty-four patients were randomly allocated to undergo GVL intubation using either GRS (GRS group) or PFS (PFS group). The total intubation time (TIT), 100-mm visual analog scale (VAS) for ease of intubation, success rate at the first attempt, use of laryngeal manipulation, tube advancement rate by assistant, and complications were recorded. Results: There was no significant difference between the GRS and PFS groups regarding TIT (50.3 ± 12.0 s in the GRS group and 57.8 ± 18.8 s in the PFS group, P = 0.108). However, intubation was more difficult in the PFS group than in the GRS group according to VAS score (P = 0.011). Cases in which the ETT was advanced from the stylet by an assistant, were more frequent in the GRS group than in the PFS group (P = 0.002). The overall incidence of possible complications was not significantly different. Conclusions: In patients with a simulated difficult airway, there was no difference in TIT using either the PFS or GRS. However, endotracheal intubation with PFS is more difficult to perform than GRS.
