BACKGROUND: Extracorporeal circulation using pump-oxygenator is an inevitable process to keep vital sign during cardiac arrest for open heart surgery. However, the diversion of blood through nonendothelialized channels appears to stimulate inflammatory response, and leukocyte activation may lead to cardiopulmonary edema. Our study evaluated the effect of leukocyte-induced cardiopulmonary edema using three different pump-oxygenator priming solutions; non-hemic crystalloid solution ; leukocyte-depleted homologous blood; non leukocyte-depleted homologous blood in priming solutions. MATERIAL AND METHOD: Each different priming solution was used on five dogs, and the effect of leukocyte-induced cardiopulmonary edema during cardiopulmonary bypass(CPB) was evaluated. For each dog after 2 hours of exracorporeal circulation and another 4 hours of post-pump period, the dog was sacrificed and its heart and lung tissues were obtained for measuring Wet/Dry ratio. Arterial O2 partial pressure(PaO2) and CO2 partial pressure(PaCO2) were checked. For the evaluation of ventilatory function, CO2 partial pressure difference between arterial blood (PaCO2) and exhaled air(EtCO2) was measured. RESULT: 1. No significant difference was seen in arterial PaO2 and PaCO2 among groups. 2. Ventilatory function evaluated by PaCO2 and EtCO2 showed no significant difference between non-hemic and blood-mixed priming solution (P<0.05). 3. Cardiac and lung Wet/Dry ratios were remarkedly lower in the leukocyte- depleted group. There was no significant difference between the non-hemic and blood-mixed groups. CONCLUSION: Based upon this result, we concluded that the leukocyte depletion from homologous blood of CPB priming solution has a beneficial effect in reducing cardiopulmonary edema compared with non leukocyte-depleted or crystalloid priming solutions.

BACKGROUND: Myocardial revascularization in patients with renal insufficiency is challenging to the cardiac surgeon, irrespective of utilizing extracorporeal circulation. This study aimed to compare the number of bypass grafts and the mid-term results and to evaluate independent survival predictors in patients with renal insufficiency undergoing on-pump or off-pump myocardial revascularization. MATERIALS AND METHODS: We retrospectively analyzed the data of 103 patients with renal insufficiency, who had isolated myocardial revascularization between January 1999 and January 2009. The patients were divided into two groups, the on-pump group and the off-pump group. RESULTS: The off-pump group received a significantly greater number of distal arterial grafts than the on-pump group. However, the mean number of total grafts, the degree of complete revascularization, and survival rate of the patients were not significantly different between the two groups. Multivariate analysis showed the independent predictors for reduced mid-term survival were the number of total grafts and postoperative periodic renal replacement therapy. Off-pump myocardial revascularization does not decrease the number of bypass grafts or influence on the mid-term results for patients with renal insufficiency, compared to on-pump myocardial revascularization. CONCLUSION: Myocardial revascularization with a large number of total grafts has a beneficial effect on survival in patients with renal insufficiency, irrespective of utilizing extracorporeal bypass.

The perforation and migration of ingested sharp metallic bodies is a rare event. A perforation of the gastrointestinal tract is difficult to accurately and quickly diagnose when there is no peritonitis or abscess formation. Patients often present with no symptoms. The discovery of a foreign body on a radiological examination of the abdomen may be made incidentally. Moreover, a history of ingestion is usually difficult to obtain. Foreign bodies after perforation have been reported to migrate to any intra-abdominal site and to extra-abdominal sites in rare cases. We report one case of young man with ingested needle in which perforated silently and migrated to the lesser omentum. A 23-year-old man presented with an incidental foreign body. He has no definite ingestion history or psychiatric disorder, but was a heavily drinker. An abdominal plain X-ray showed a needle in the upper abdominal area. Computed tomography revealed the foreign body to be located beneath the liver and in the lesser omentum. The patient underwent a laparoscopic examination performed in the supine position. After creating a pneumoperitoneum by CO2 gas insufflation at 12 mmHg, 3 trochars (two 5-mm and 12-mm) were introduced at each subcostal and supraumbilical area. Surgical management using laparoscopic extraction was successful. The patient was discharged in good health on the 3rd day after the procedure. Laparoscopy can be used to remove ingested foreign bodies when surgery is indicated.

BACKGROUND: Emergence agitation frequently occurs after desflurane anesthesia in children.Nalbuphine, because of its sedative and analgesic properties, might be useful for the management of this side effect.We studied the effect of nalbuphine on recovery characteristics and emergence agitation after desflurane anesthesia in children for strabismus surgery. METHODS: 41 patients (3-14 yr) scheduled for pediatric strabismus surgery were included.All children received ketamine 0.5 mg/kg intravenously before entering the operating room.After intravenous induction with thiopental and rocuronium to facilitate endotracheal intubation, patients were randomly assigned to receive saline, or nalbuphine 0.2 mg/kg respectively. Anesthesia was maintained with desflurane 4-6% with N2O : O2 = 2 : 1.At the end of anesthesia, time to cough, extubation, movement, eye opening and discharge were recorded.Emergence agitation was recorded by three point rating scale. RESULTS: Agitation scores were significantly different between the two groups (P < 0.01).Time to extubation and movement were similar between two groups.Time to eye opening was significantly increased in nalbuphine group (P < 0.05).But, there was no difference in time to discharge from the recovery room to the ward between the two groups. CONCLUSIONS: In children undergoing strabismus surgery with desflurane anesthesia, nalbuphine 0.2 mg/kg administered immediately after induction reduced incidence of emergence agitation without delaying discharge from recovery room.

BACKGROUND: Second-line chemotherapy offers advanced non-small cell lung cancer (NSCLC) patients a small, but significant increase in survival. Docetaxel is usually administered as a 3-week schedule, yet there is significant toxicity with this therapy. Therefore, a weekly schedule has been explored in several previous trials. In this retrospective study, we compared the efficacy and safety of a weekly schedule and a 3-week schedule of docetaxel monotherapy in a second-line setting. METHODS: Docetaxel was administered as 75 mg/m2 on day 1 every 3 weeks or as 37.5 mg/m2 on day 1 and 8 every 3 weeks until disease progression or severe toxicity developed. RESULTS: From October 2003 to March 2006, a total of 37 patients received docetaxel monotherapy and 36 patients could be evaluated. A total of 135 cycles were administered and then evaluated. The median overall survival was 13.3 months (95% confidence interval: 6.3~20.3) for the weekly schedule and 10.7 months (95% confidence interval: 8.3~13.0) for the 3-week schedule (p=0.41). The median time to progression was 3.0 months (95% confidence interval: 1.9~4.0) and 2.8 months (95% confidence interval: 1.0~4.6), respectively (p=0.41). The response rate was 16.7% for the weekly schedule and 21.1% for the 3-week schedule. The major form of hematologic toxicity was grade 3-4 neutropenia (3-week: 38.9%, weekly: 9.5%). The non-hematologic toxicities were similar between the two schedules. There were no treatment-related deaths. CONCLUSIONS: A docetaxel weekly schedule was very tolerable and it had comparable activity to that of the 3-week docetaxel schedule. Considering the efficacy and tolerability, a docetaxel weekly schedule can be an alternative schedule for the standard treatment of NSCLC in a second-line setting.

Traumatic ventricular septal rupture following traffic accident is presummed to occur by external compression of the heart during late diastole or isovolumetric systole when the ventricular chambers are full and the valves are closed. Isolated ventricular septal rupture following non-penetrating chest trauma is known to be extremely rare. We report a 29-year-old man with suddenly developed ventricular septal rupture follwing nonpenetrating chest trauma by traffic accident, which he was died suddenly due to cardiac arrest in front of an operation.

PURPOSE: Lymphatic spread of tumor is an important prognostic factor for patients with non-small cell lung carcinoma (NSCLC). Vascular endothelial growth factor-C (VEGF-C) and VEGF-D play important roles in lymphangiogenesis via the VEGF receptor 3 (VEGFR-3). We sought to determine whether VEGF-C, VEGF-D and VEGFR-3 are involved in the clinical outcomes of patients with resected NSCLC. MATERIALS AND METHODS: Using immunohistochemical staining, we investigated the protein expressions of VEGF-C, VEGF-D and VEGFR-3 in the tissue array specimens from patients who underwent resection for NSCLC. The immunoreactivity for p53 was also examined. The clinicopathological implications of these molecules were statistically analyzed. RESULTS: Analysis of a total of 118 specimens showed that VEGF-C, VEGF-D and their co-expression were significantly associated with more advanced regional lymph node metastasis (p=0.019, p=0.044 and p=0.026, respectively, N2 versus N0 and N1). A VEGFR-3 expression had a strong correlation with peritumoral lymphatic invasion (p=0.047). On the multivariate analysis for survival and recurrence, pathologic N2 lymph node metastasis was the only independent prognostic factor, but none of the investigated molecules showed any statistical correlation with recurrence and survival. CONCLUSIONS: The present study revealed that high expressions of VEGF-C and VEGF-D were strongly associated with more advanced regional lymph node metastasis in patients with resected NSCLC.

BACKGROUND AND OBJECTIVES: Previous studies have suggested that women with AMI are less aggressively managed than men. The aim of this study was to assess the differences between the sexes, in terms of the medical and invasive coronary procedures, in AMI patients during the 1990s, and the association to in-hospital mortality. SUBJECTS AND METHODS: In 1758 AMI patients, the baseline clinical characteristics, initial management and in-hospital outcomes, were studied. RESULTS: The women, on average, were older than men (68.8+/-10.6 versus 59.2+/-12.3, p<0.01), with a higher prevalence of diabetes and hypertension. Women received heparin and b-blockers less often than men. The unadjusted rates of thrombolysis, angiography and PTCA use were lower in women than men, but not after covariate adjustment. The in-hospital mortality was higher in women than men (11.7% versus 8.1%, odd ratio (OR) 1.51, 95% CI 1.09 to 2.11, p<0.05), but this difference was not significant after adjustment for age (adjusted OR 0.98, 95% CI 0.69 to 1.40, p=NS). CONCLUSION: Women with AMI are less aggressively managed than men, and have higher in-hospital mortalities. The difference in outcome seems to be associated with increased age, with a greater co-morbidity of women.
