AbstractAbstract PDF
We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

AbstractAbstract PDF
Tracheal tumors are very rare disease, which may cause dyspnea, obstructive pneumonia and life-threatening hypoxemia, depending on the site of the lesion and the severity of the narrowing. Such patients frequently die within hours or days due to suffocation. Patients who expressed upper airway stenosis, should be secured the airways prior to the diagnosis and treatment commonly. Then, treatment plan should be determined. For the relief of such stenosis, various modalities of therapy including surgery, laser photoresection, balloon dilatation and sometimes stent insertion have been used. Tracheobronchial stent insertion has been a good therapeutic option in these patients in point of avoiding morbidities associated with surgery. We report a case of repeated tracheobronchial stenosis by infiltrating tumor mass after metallic stent insertion in a 48-year-old man. The patient was treated successfully by Natural stent insertion with rigid bronchoscopy after removal of previous inserted metallic stent.

AbstractAbstract PDF
BACKGROUND
There are only inadequate studies on the characteristics of severe pneumonia in the patients who have solid cancer and who are treated with cytotoxic chemotherapy and also on the usefulness of the various severity index scores.
METHODS
We retrospectively reviewed 31 patients who were treated with cytotoxic chemotherapy because of solid cancer and who were admitted to the medical ICU at Samsung Medical Center from April 2007 to August 2008.
RESULTS
The median age of the 31 patients was 64 years old (34-79). The types of solid cancer were lung cancer (19, 61.3%), gastroesophageal cancer (4, 12.9%), breast cancer (2, 6.5%), liver cancer (1, 3.2%), ovarian cancer (1, 3.2%) and other types of cancer (4, 12.9%). The hospital mortality rate was 64.5%. We were able to determine the pathogen of 19 (61.3%) patients; S. pneumoniae (6), S. aureus (3), Candida species (3), P. aeruginosa (2), K. pneumoniae (1), Pneumocystis jiroveci (1) and others (3). There were no statistically differences of the laboratory data and severity index scores (PSI, CURB-65, APACHE II, SOFA, SAPS 3) between the survivors and nonsurvivors, except the P/F ratio.
CONCLUSIONS
The hospital mortality rate of severe pneumonia in patients who had solid cancer and who received cytotoxic chemotherapy was high. The major pathogen was S. pneumoniae. The severity indexes for general pneumonia were not useful to these patients.

AbstractAbstract PDF
BACKGROUND
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the leading causes of death after lungresection. Neutrophil elastase is thought to be an important mediator in the pathogenesis of ALI. Sivelestat is a new neutrophil elastase inhibitor which may improve the outcome in patients with ALI/ARDS after lung resection. The objective of this study was to determine whether or not sivelestat can reduce mortality in patients with ALI after pulmonary resection for lung cancer.
METHODS
This study was a retrospective case-control study of twenty three patients who developed ALI/ARDS within seven days of lung resection for lung cancer. The control group (n = 12) received standard care, while the sivelestat group (n = 11) received a continuous infusion of sivelestat (0.2 mg/kg/hr) for seven days in addition to standard care.
RESULTS
There was no significant difference in the baseline characteristics between the control and sivelestat groups, except for heart rate. Six of twelve patients (50%) in the control group survived, while seven of twelve patients (64%) survived in the sivelestat group (p = 0.34). There was also no significant difference between the two groups in the progression to ARDS. In the sivelelestat group, survivors had lower APACHE II and SOFA scores than the patients in the control group.
CONCLUSIONS
There was no additional effect of a neutrophil elastase inhibitor in the treatment of ALI after pulmonary resection for lung cancer.

AbstractAbstract PDF
BACKGROUND
The role of glucocorticoids for treating persistent acute respiratory distress syndrome (ARDS) is matter of debate. In the previous studies, the side effects of moderate doses of glucocorticoids might have negated positive effects of glucocorticoids. This study aimed at determining the feasibility of administering "low-dose" glucocorticoid to treat the patients who suffer with persistent ARDS.
METHODS
We retrospectively reviewed the medical records of twelve patients with ARDS of at least seven days' duration and who were treated with "low-dose" glucocorticoid (starting dose of 1 mg/kg) between June 2007 to December 2008. The patients were divided by whether or not they were successfully weaned from the ventilator after glucocorticoid therapy. The baseline characteristics and physiologic parameters were recorded for up to 7 days after starting glucocorticoid therapy.
RESULTS
Five patients (42%) were included in the weaned group. There was no significant difference in the clinical characteristics and the physiologic parameters between the two groups on the day of ARDS. Yet the weaned group had a significantly lower Sequential Organ Failure Assessment (SOFA) score, as compared to that of the failed group [3 (3-6) vs 8 (5-12), p = 0.009)] at start of glucocorticoid treatment. After 3 days of glucocorticoid therapy, there was significant improvement in the PEEP, the PaO2/FIO2 ratio, the PCO2, the SOFA score and the Murray Lung Injury Score of the weaned group, as compared to that of the failed group. There were no major neuromuscular side effects from the therapy.
CONCLUSIONS
This study suggests that the "low-dose" glucocorticoid therapy is feasible and that the SOFA score and the physiologic parameters may assist in determining whether or not to initiate and to continue glucocorticoid therapy for the patients who are suffering with persistent ARDS.

AbstractAbstract PDF
BACKGROUND
The prognosis of hemato-oncology (HMO) patients admitted to the intensive care unit (ICU) is poor and predicting the mortality is important for decision making at the time of ICU admission and for administering aggressive treatment.
METHODS
We retrospectively reviewed 309 patients who were admitted to the medical ICU (MICU) at Samsung Medical Center from July in 2005 to June in 2006. We calculated their Simplified Acute Physiology Score II (SAPS II) and the Sequential Organ Failure Assessment (SOFA) score at the time of ICU admission and we investigated the relationship between the two scoring systems and the hospital mortality.
RESULTS
Among the 309 patients, the hospital mortality was 41.2%, and the mean SAPS II/SOFA score at ICU admission was 45.4 +/- 19.5/8.1 +/- 4.6. Seventy-nine (25.6%) patients had hemato-oncological diseases. Their hospital mortality was 65.8%, and the mean SAPS II/SOFA score at the time of ICU admission was 53.9 +/- 18.6/9.7 +/- 4.4, which was higher than that of the non-HMO patients (p = 0.00). The area under the receiver operating characteristic (ROC) curves for the SAPS II/SOFA score for predicting the mortality was 0.794 +/- 0.05/0.785 +/- 0.051 (p = 0.00/p = 0.00) for the HMO patients. There was no significant difference in discrimination ability between the two scoring systems (p > 0.05). None of the HMO patients with a SAPS II/SOFA score of 70/14 or higher survived.
CONCLUSIONS
Both the SAPS II and SOFA scores at the time of ICU admission were similarly effective for predicting the hospital mortality. The two scoring systems could be useful tools for decision making at the time of ICU admission and for administering aggressive treatment.

AbstractAbstract PDF
Extracorporeal membrane oxygenation (ECMO) is a life-sustaining salvage therapy applied to the patient with acute heart failure or respiratory failure which is considered curable, but uncorrectable by conventional means. Recently, accumulating data has shown the survival benefit of ECMO in patients with acute fatal cardiopulmonary decompensation. Here, we report a series of cases of successful ECMO treatment in patients with acute cardiopulmonary insufficiency. Case 1: A patient with progressive respiratory failure on mechanical ventilation after pneumonectomy was managed satisfactorily using a veno-venous ECMO. Case 2: A veno-arterial ECMO was used to support a patient with vasopressor refractory septic shock. After 5 days of treatment, the patient was successfully weaned from ECMO. Case 3: A patient in cardiac arrest after the orthopedic surgery was resuscitated using a veno-arterial ECMO. Pulmonary angiography on ECMO revealed massive pulmonary thromboembolism and embolectomy was thoroughly performed under the support of ECMO.
