Tumor-draining lymph node (TDLN) lymphocytes contain immunologically sensitized to tumor but functionally deficient T cells. The 30 kDa protein antigen, a major secreted protein antigen of Mycobacterium tuberculosis, exhibits strong T cell stimulatory effect. In this study, it examined that the feasibility of using M tuberculosis 30 kDa antigen to stimulate tumor-draining lymph node cells for the generation of specific immune effector cells. Freshly isolated TDLN lymphocytes could directly respond to the 30 kDa antigen alone and their proliferative responses were markedly augmented by stimulation with rIL-2. TDLN cells were stimulated with the 30 kDa antigen for various time intervals and examined for the induction of IFN-r and IL-4 mRNA using RT-PCR. The expression of IFN-r mRNA was greatly augmented after 1 wk, whereas IL-4 mRNA is markedly decreased after 1 wk. Cytotoxic T cell activities induced by the 30 kDa antigen was also evaluated. TDLN cells stimulated with the 30 kDa antigen alone were able to generate remarkable cytotoxic response to K562 or Daudi cell lines after 6 days of culture. And their cytotoxic effects were highly augmented by stirnulation with rIL-2. These results suggest that the 30 kDa antigen of M. tuberculosis may selectively activate Thl cells of TDLN lymhocytes and induce the cytotoxic T cell activities. In conclusion, the 30 kDa antigen can be used as a biologic response modifier in tumor immunology.

Pulmonary thromboembolism (PTE) is a serious postoperative complication. Prompt diagnosis of PTE is important but it is difficult because clinical manifestations of PTE are not obvious in most cases. A 59 year-old woman received cholecystectomy and choledocholithotomy under general anesthesia. At the 9th postoperative day, syncope, hypoxemia and hypotension were developed suddenly and the patient was transfered to intensive care unit. PTE was suspected with hemodynamic monitoring from pulmonary arterial catheter and echocardiography and diagnosed with lung perfusion scan and venogram of lower extremities. Proper cardiopulmonary support was done and the patient was recovered and discharged in improved condition. In conclusion, if a patient have syncopal attack with shock in postoperative period, PTE must be thought to be an one of possible causes of syncope and thoroughly investigated.

We report two patients with multiple peculiar skin eruptions and polyclonal hypergammaglobulinemia. Both patients visited our hospital for the evaluation of asymptomatic multiple nodular eruptions on almost their entire body except for the lower extremities. Histologic examinations disclosed prominent infiltration of plasma cells and lymphoid follicular hyperplasia in the dermis but these plasma cells showed neither a mitotic figure nor atypicalities. Laboratory examinations showed polyclonal hypergammaglobulinemias and increased erythrocyte sedimentation rates. In spite of various investigations, the cause of the hypergammaglobulinemia remained obscure.

Blunt trauma of the chest and abdomen frequently result in cardiac injury. We experienced a 47 year-old male patient of myocardial contusion with aortic insufficiency after blunt chest trauma. On the secondd day after admission, the patient developed sudden hypoxemia and wide pulse pressure. A pulmonary arterial catheter was inserted and initial cardiac output and pulmonary capillary wedge pressure was 3.56 L/min/m(2) and 32 mmHg, respectively. There was akinesia of the anterior septum, anterior wall, inferior wall and inferior septum with aortic regurgitation(I/IV), and the ejection fraction was 25% on echocardiogram. Myocardial contusion with valvular injury was suspected. Dobutamine infusion was started and after five days the pulmonary capillary wedge pressure was decreased to 14 mmHg. The ejection fraction was increased to 69% in spite of decreasing dobutamine but aortic regurgitation(II/VI) remained. Therefore echocardiogram and pulmonary artery catheterization will be helpful to diagnose suspected cardiac contusion and for better outcome.

PURPOSE: The purpose of this study was to explore the main prerequisite for Korean Advance Directives [KAD] to ensure their better use. METHODS: Data were collected from two focus group interviews and individual email responses. Study participants were 5 doctors and 6 nurses. All interview data were transcribed and analyzed using qualitative content analysis. RESULTS: Three main themes emerged; establishing a philosophy of KAD, protocol to practice KAD, and the KAD document itself. A philosophy is needed to ensure individual needs, consensus to practice AD and identify principle agents. The core of protocol was found to be as follows; 1) process, 2) premise, 3) procedure, 4) contextual preparation, 5) timing, 6) feasibility. Component and feasibility need to be established for the document itself. CONCLUSION: For a positive acceptance of KAD in Korean society, a culture sensitive, reality based, and user friendly AD needs to be developed.

BACKGROUND: To maintain adequate oxygen delivery and oxygen consumption is essential to care of the critically ill patients. The authors undertook this study to evaluate the patterns of oxygen delivery and oxygen consumption in hemodynamically unstable patients. METHODS: Twenty hemodynamically unstable patients were studied. Pulmonary artery catheters were inserted and the hemodynamic variables including oxygen delivery and oxygen consumption were calculated immediately, and 1, 8, 24 hours, respectively after catheterization, and immediately before catheter removal. Patients were divided into survivor and nonsurvivor groups, and the hemodynamic data were compared. The same patients were divided into septic and nonseptic patient groups and same study was done. RESULTS: There were no statistical differences in oxygen delivery and oxygen consumption between the survivors and the nonsurvivors, and the septic and the nonseptic patients. But oxygen delivery and oxygen consumption of the survivors were higher than those of the nonsurvivors. CONCLUSIONS: Although we could not find statistical significance, we concluded that supranormal level of oxygen delivery and oxygen consumption could improve the outcome of critically ill patients.

PURPOSE: The treatment of a clinically node-positive (cN+) neck is important in the management of oral cavity squamous cell carcinoma (OSCC). However, the extent of neck dissection (ND) remains controversial. The purpose of our study was to evaluate whether level IV or V can be excluded in therapeutic ND for cN+ OSCC patients. MATERIALS AND METHODS: We performed a retrospective chart review of 92 patients who underwent a comprehensive or selective ND as a therapeutic treatment of cN+ OSCC from January 1993 to February 2009. RESULTS: The incidence rate of metastasis to level IV or V was 22% (16 of 72) on the ipsilateral neck. Of 67 cases without clinically suspicious nodes at level IV or V, 11 cases (16%, 11 of 67) had pathologically proven lymphatic metastasis to level IV or V. Only a nodal staging above N2b was significantly relevant with the higher rate of level IV or V lymph node metastasis (p=0.025). In this series, selective ND, combined with proper adjuvant therapy, achieved regional control and survival rates comparable to comprehensive ND in patients under the N stage of cN2a OSCC. CONCLUSION: In conclusion, level IV and V patients can avoid recurrence under cN2a OSCC.

Peripartum cardiomyopathy is a myocardial disease associated with pregnancy and leading to heart failure. A twenty-eight years old primipara was scheduled for a cesarean section due to a twin pregnancy. She had no previous cardiac or other systemic illness. But periodic episode of sudden hypertension, tachycardia, hypoxemia(PaO2/FiO2=58) and pulmonary edema were developed in the perioperative period. After being transferred to the intensive care unit, mechanical ventilation with positive end expiratory pressure was applied for six days and pulmonary infiltration subsided. However, two days after extubation, acute pulmonary edema redeveloped in both lung fields in spite of fluid restriction. In echocardiogram demonstrated global hypokinesia of the left ventricle with an ejection fraction of 31%. Dobutamine infusion was started and one day after infusion the pulmonary edema subsided. In conclusion echocardiogram would be helpful for diagnosis of peripartum cardiomyopathy and adequate cardiac support with assisted ventilation will improve prognosis.

BACKGROUND: Midazolam is distinguished from other benzodiazepines by its water solubility, rapid onset, short duration, and lack of accumulation of active metabolites. These pharmacokinetic cbaracteristics support its use by continuous infusion. We evaluated the continuous infusion dose of midazolain for adequate sedation of ventilated patients with hemodynamic and respiratory monitoring. METHODS: We started continuous infusion of midazolam at a rate of 0.5~1.0 ug/kg/minute after bolus injection of 3.0 to 5.0 mg and adjusted infusion dose monitoring sedation scale in the 15 patients. Blood pressure, heart rate and central venous pressure were monitored before and 30 minute, 1, 2, 3 and 6 hours after midazolam infusion. Arterial blood gases were measured and peak inspiratory pressure was monitored. We evaluated liver and kidney function before start of infusion and after discontinuation of midazolam infusion. RESULTS: The mean loading dose, infusion rate and total dose of midazolam were 4.1+/-0.9 mg, 1.2+/-0.4 ug/kg/minute and 251.9+/-84.0 mg. The mean duration of infusion was 59.0+/-37.0 hours. After infusion, systolic and diastolic blood pressure and heart rate and central venous pressure remained stable when compared with those of the preinfusion state. Arterial blood gas and peak inspiratory pressure remained unchanged. The function of liver and kidney did not deteriorate after infusion. CONCLUSIONS: Continuous infusion of midazolam at a rate of 1.2+/-0.4 ug/kg/minute after 4.1+/-0.9 mg intravenous bolus injection was a safe and effective method for sedation of ventilated patients in intensive care unit without hemodynamic disturbance.

Urine discoloration occurs in the intensive care unit (ICU) due to many causes such as medications, metabolic disorders, and infections. Propofol is advocated as one of the first line sedatives in the ICU, but it is not well known to the intensivists that propofol can induce urine color change. We experienced two cases of green urine after propofol infusion. Propofol should be warranted as the cause of urine discoloration during ICU stay.
