OBJECTIVE: The aim of this study was to evaluate the consistency between revised prognostic score derived from the Tokuhashi scoring system(TSS) and the actual patient survival period after surgical treatment at our institution. METHODS: From 1998 to 2005, surgically treated 44 patients with metastatic spine tumors were reviewed retrospectively at our institution. Among these 44 patients, 32 had died, 2 were alive at the time of the last follow-up evaluation, and 10 were lost to the follow-up. Only 32 patients who died after surgery have been investigated in this study. Preoperatively, patients were staged serveral standard diagnostic modalities, such as, plain radiographs, computed tomography, magnetic resonance imaging and etc. Each patient was evaluated using the TSS and placed in one of three groups depending upon this evaluation. RESULTS: The actual mean(+/-SD) survival period was 6.6 months(+/-1.14) for the first group (predicted survival periods in revised TSS, less than 6 months), 15.1 months(+/- 5.38) for the second group(predicted survival periods in revised TSS, 6 months or more) and 37.5 months(+/-8.70) for the third group(predictied survival period in revised TSS, 1 year or more). The survival periods for these groups were significantly different(p=0.0006). Applying the TSS for evaluation of prognosis of metastatic spinal tumors was found to be very reliable results with a statistically significance. Of six parameters measured in the TSS, Extraspinal bone metastases, metastases to the major internal organs, the primary tumor site contributed to predicting the survival periods. CONCLUSIONS: This study has revealed that the revised prognostic score resulting from the TSS predicts actual survival periods remarkably well. Hence, we thought that the revised TSS could be useful and reliable tool in prognosis of metastic spinal tumors.

OBJECT: The aim of this study is to analyze the statistical significance between the clinical result and subsidence and lordosis loss after anterior cervical discectomy and interbody fusion operation for degenerative cervical disc diseases. METHODS: From January 2004 to December 2006, retrospective study of 82 patients with symptomatic degenerative cervical disc disease who underwent anterior cervical discectomy and interbody fusion using the PEEK SolisTM cage and the carbon composite Osta-PekTM cage with autologous bone graft was done. Mean follow-up period was 13.2 months. Clinical results were assessed by bone fusion, subsidence, segmental lordosis loss and Odom's criteria. RESULTS: Of the 82 patients, single level fusion was accomplished in 67 patients and two-level fusion in 15 patients. Total accomplished fusion level was 97: C3/4 in 9 levels, C4/5 in 29 levels, C5/6 in 37 levels, C6/7 in 21 levels, C7/T1 in 1 level. 9 patients fit into complete resolved, 59 improved and 14 not changed, thus the success rate in clinical outcome was 82.9%. Bone fusion was successfully confirmed in the total of 82 patients. The height of disc space was decreased to 2.13+/-2.16mm: 2.64+/-1.81mm in the Osta-PekTM cage, 2.44+/-1.36mm in the PEEK SolisTM cage. The Osta-PekTM cage provided higher subsidence tendency than the PEEK SolisTM cage in our study. However, there was no statistical significance between the two cage groups. The subsidence and lordosis loss showed poor clinical outcome, but there was no statistical significance. CONCLUSIONS: There were no significant differences between the Osta-PekTM cage and PEEK SolisTM cage on clinical outco mes. Both cages showed low subsidences and lordosis loss with good fusion rate and clinical outcome.

BACKGROUND: Synergistic antitumor effects of the combined chemoimmunotherapy based on dendritic cells have been reported recently. The aim of this study is to search new applicability of gefitinib into the combination treatment through the confirmation of gefitinib effects on the monocyte derived dendritic cells (moDCs); most potent antigen presenting cell (APC). METHODS: Immature and mature monocyte-derived dendritic cell (im, mMoDC)s were generated from peripheral blood monocyte (PBMC) in Opti-MEM culture medium supplemented with IL-4, GM-CSF and cocktail, consisting of TNF-alpha (10 ng/mL), IL-1beta (10 ng/mL), IL-6 (1,000 U/mL) and PGE2 (1 micro/mL). Various concentrations of gefitinib also added on day 6 to see the influence on immature and mature MoDCs. Immunophenotyping of DCs under the gefitinib was performed by using monoclonal antibodies (CD14, CD80, CD83, CD86, HLA-ABC, HLA-DR). Supernatant IL-12 production and apoptosis of DCs was evaluated. And MLR assay with [3H]-thymidine uptake assay was done. RESULTS: Expression of CD83, MHC I were decreased in mMoDCs and MHC I was decreased in imMoDCs under gefitinib. IL-12 production from mMoDCs was decreased under 10 microM of gefitinib sinificantly. Differences of T cell proliferation capacity were not observed in each concentration of geftinib. CONCLUSION: In spite of decreased expressions of some dendritic cell surface molecules and IL-12 production under 10 microM of gefitinib, significant negative influences of gefitinib in antigen presenting capacity and T cell stimulation were not observed.

Churg-Strauss syndrome (CSS) is a disorder that is characterized by asthma, hypereosinophilia and systemic vasculitis affecting a number of organs. The manifestations of acute cholecystitis and diffuse alveolar hemorrhage are rarely reported in CSS. A 22-year-old woman with bronchial asthma visited our hospital complaining of right upper quadrant pain with a sudden onset. The abdominal computed tomography (CT) scan revealed gall bladder edema consistent with acute cholecystitis. On the initial evaluation, marked hypereosinophilia was observed in the peripheral blood smear. The nerve conduction velocity measurements and a skin biopsy performed to confirm the organ involvement of disease indicated typical mononeuritis multiplex and necrotizing vasculitis, respectively, which was complicated with CSS. On the 12th hospital day, ground glass opacity and consolidations were newly developed on both lung fields. The bronchoalveolar lavage (BAL) fluid showed increasing bloody return in sequential aliquots that were characteristic of a diffuse alveolar hemorrhage. We report a case of CSS with acute cholecystitis and diffuse alveolar hemorrhage.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is one of the leading causes of disability and mortality worldwide. The aim of this study was to evaluate the risk factors associated with recurrent hospital admissions for exacerbation of COPD in Korea. METHODS: A retrospective study of 77 consecutive patients hospitalized for exacerbation of COPD at Pusan National University Hospital during the time period January 2005 to May 2008 was performed. The information was collected from the hospitalization period: clinical information, spirometric measures, and laboratory variables. In addition, socioeconomic characteristics, co-morbidity, anxiety, and depression were reviewed. Frequent readmission was defined as 2 or more hospitalizations in the year following discharge. RESULTS: During the 1-year period after discharge, 42 patients (54.6%) reported one hospital admission and 35 patients (45.4%) reported 2 or more hospital readmissions. Among the 35 frequent readmission patients, 4 had more than 10 readmissions. Univariate analysis showed that a body mass index (BMI) <18.5 kg/m2, duration >36 months, forced expiratory volume in 1 second (FEV1) <50% predicted, arterial CO2 partial pressure (PaCO2) >40 mm Hg, and arterial oxygen saturation (SaO2) <95% at discharge were associated significantly with frequent readmissions. The multivariate analysis revealed that BMI <18.5 kg/m2, PaCO2 >40 mm Hg at discharge were independently associated with frequent readmissions for exacerbation of COPD. CONCLUSION: Frequent readmissions for exacerbation of COPD were associated with low BMI and hypercapnia at discharge.

BACKGROUND: We evaluated the clinical outcomes and prognostic factors of patients requiring prolonged mechanical ventilation (PMV), defined as ventilator care for > or =21 days, who were admitted to the medical intensive care unit (ICU) of a university hospital in Korea. METHODS: During the study period, a total of 2,644 patients were admitted to the medical ICU, and 136 patients (5.1%) were enrolled between 2005 and 2010. RESULTS: The mean age of the patients was 61.3+/-14.5 years, and 94 (69.1%) were male. The ICU and six-month cumulative mortality rates were 45.6 and 58.8%, respectively. There were 96 patients with tracheostomy placement after admission and their mean period from admission to the day of tracheostomy was 21.3+/-8.4 days. Sixty-three patients (46.3%) were successfully weaned from ventilator care. Of the ICU survivors (n=74), 34 patients (45.9%) were transferred to other hospitals (not university hospitals). Two variables (thrombocytopenia [hazard ratio (HR), 1.964; 95% confidence interval (CI), 1.225~3.148; p=0.005] and the requirement for vasopressors [HR, 1.822; 95% CI, 1.111~2.986; p=0.017] on day 21) were found to be independent factors of survival on based on the Cox proportional hazard model. CONCLUSION: We found that patients requiring PMV had high six-month cumulative mortality rates, and that two clinical variables (measured on day 21), thrombocytopenia and requirement for vasopressors, may be associated with prognostic indicators.

Actinomycosis is a chronic pyogenic granulomatous disease, defined as infection caused by gram-positive anaerobic Actinomyces, mainly Actinomyces Israelii. It colonize in human oral cavity, gastrointestinal tract, or genital tract of female, and characterized by lesion that secretes sulfur granules. Generally, abdominal actinomycosis shows chronic disease progression without any typical clinical symptoms, sometimes forming an inflammatory mass within the abdominal cavity. Due to this fact, it is frequently mistaken as malignant neoplasm, diagnosed only after operation. We report this case after diagnosing abdominal actinomycosis without an open abdominal surgery ; colonoscopy and biopsy was carried out in a patient with mucosal changes and luminal narrowing of transverse colon on colon study, ultimately diagnosing abdominal actinomycosis without an open abdominal surgery.

BACKGROUND: Bronchoalveolar lavage (BAL) is a useful technique to recover lower airway fluid and cells involved in many respiratory diseases. Miliary tuberculosis is potentially lethal, but the clinical manifestations are nonspecific and typical radiologic findings may not be seen until late in the course of disease. In addition, invasive procedures are often needed to confirm disease diagnosis. This study analyzed the cells and the T-lymphocyte subset in BAL fluid from patients with miliary tuberculosis to determine specific characteristics of BAL fluid that may help in the diagnosis of miliary tuberculosis, using a less invasive procedure. METHODS: On a retrospective basis, we enrolled 20 miliary tuberculosis patients; 12 patients were male and the mean patient age was 40.5+/-16.2 years. We analyzed differential cell counts of BAL fluid and the T-lymphocyte subset of BAL fluid. RESULTS: Total cells and lymphocytes were increased in number in the BAL fluid. The percentage of CD4+ T-lymphocytes and the CD4/CD8 ratio in BAL fluid were significantly decreased and the percentage of CD8+ T-lymphocytes was relatively higher. These findings were more prominent in patients infected with the human immunodeficiency virus (HIV). In the HIV-infected patients, the proportion of lymphocytes was significantly higher in BAL fluid than in peripheral blood. There were no significant differences between the BAL fluid and the peripheral blood T-lymphocytes subpopulation. CONCLUSION: BAL fluid in patients with miliary tuberculosis demonstrated lymphocytosis, a lower percentage of CD4+ T-lymphocytes, a higher percentage of CD8+ T-lymphocytes, and a decreased CD4/CD8 ratio. These findings were more significant in HIV-infected subjects.

BACKGROUND/AIMS: Pandemic influenza A (H1N1) virus infection presents with variable severity. However, little is known about clinical predictors of disease severity. We studied the clinical predictors of severe pandemic H1N1 pneumonia and their correlation with radiological findings. METHODS: We reviewed medical and radiological records of adults with pandemic H1N1 pneumonia. After classification of patients into severe and non-severe groups, the following data were evaluated: demographic data, pneumonia severity index (PSI), CURB65, risk factors, time to first dose of antiviral medication, routine laboratory data, clinical outcome, and radiological characteristics. RESULTS: Of 37 patients with pandemic H1N1 pneumonia, 12 and 25 were assigned to the severe and non-severe groups, respectively. PSI score, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dyhydrogenase (LDH) levels were higher in the severe group than in the non-severe group (p = 0.035, 0.0003, 0.0023, and 0.0002, respectively). AST, ALT, and LDH levels were positively correlated with the radiological findings (p < 0.0001, 0.0003, and < 0.0001, respectively) and with the number of involved lobes (p = 0.663, 0.0134, and 0.0019, respectively). The most common finding on high resolution computed tomography (HRCT) scans was ground-glass attenuation with consolidation (n = 22, 60%), which had a predominantly patchy distribution (n = 31). CONCLUSIONS: We demonstrated a positive correlation between clinical findings, such as serum AST, ALT, and LDH levels, and radiological findings. A combination of clinical and HRCT indicators would be useful in predicting the clinical outcome of pandemic H1N1 pneumonia.
