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.

BACKGROUND: Tricuspid regurgitation has been considered as a secondary lesion when it is combined with left valvular heart diseases. However, there have been some reports which show that tricuspid regurgitation keeps going and results in congestive heart failure even after a successful operation for left valvular heart disease. So far, there are no definite operation indications and predictive factors for the tricuspid regurgitation which is resulted from the left sided valvular heart disease. We designed this study to evaluate the effects of pulmonary artery pressure and left ventricular ejection fraction on the prognosis of tricuspid regurgitation, and to make an operation indication for the patients with secondary tricuspid regurgitation. MATERIAL AND METHOD: We reviewed the medical records of patients who underwent surgery for the left sided valvular heart disease with tricuspid regurgitation and were followed for more than 1 year with echocardiograms. There was a total of 114 cases. We compared the grades of tricuspid regurgitations and pulmonary artery pressures and left ventricular ejection fractions on the basis of echocardiograms which were checked preoperatively and on the last follow up. RESULT: There were 43 cases of tricuspid annuloplasty. In these patients, the grades of tricuspid regurgitations were improved in 42 cases (97.7%). But in 71 cases without annuloplasty, 29 cases (41%) were improved, 32 cases (45%) had no change, and 10 cases (14%) were aggravated. This finding shows significant differences in the prognoses of tricuspid regurgitations between the two groups (p<0.05). There was no difference in pulmonary artery pressures and ejection fractions between the patients who showed progression of tricuspid regurgitations and those who didn't (p>0.05). The improvements of tricuspid regurgitations are not statistically related to the changes of pulmonary artery pressures or left ventricular ejection fractions. CONCLUSION: This study shows that it is impossible to predict the prognoses of tricuspid regurgitations with preoperative pulmonary artery pressures or left ventricular ejection fractions. Also, the excellent results of tricuspid annuloplasty is proven in controlling the secondary tricuspid regurgitations. Therefore, when tricuspid regurgitation is detected preoperatively, the procedures to correct the tricuspid regurgitation at the time of the operation for the left-sided valvular heart disease must be considered positively, regardless of the grades of tricuspid regurgitations, to prevent significant tricuspid regurgitation that may develop later.

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.

Recently the transcriptional up-regulation of human beta-defensin 2 (HBD-2) by lipopolysaccharide (LPS) was found to be associated with NF-kappaB binding site. Although the general mechanisms of NF-kappaB activation by LPS stimulation are well understood, less is known about the signal transduction pathway leading to LPS-induced NF-kappaB activation in human corneal epithelial (HCE) cells. The aim of this study was to investigate the intracellular signals involved in LPS-induced HBD-2 mRNA expression in HCE cells. Pretreatments of inhibitors for NF-kappaB, protein tyrosine kinase, p38 mitogen activated protein kinase (MAPK), and c-Jun N-terminal kinase (JNK) attenuated the LPS-induced NF-kappaB DNA binding activity and HBD-2 mRNA expression. Furthermore, pretreatments with inhibitors for protein kinase C (PKC), phosphatidylcholine-phospholipase C, phosphatidylinositol-phospholipase C, or phosphatidate phosphohydrolase prevented LPS-induced HBD-2 mRNA expression and HBD-2 prmoter-driven luciferase activity. However, the increased expression of HBD-2 mRNA and the increased DNA binding activity of NF-kappaB induced by LPS were not changed by the blockage of extracellular signal-regulated kinase (ERK) and of addition of antioxidants. Forskolin, a protein kinase A (PKA) agonist did not induce HBD-2 mRNA expression. These data demonstrate that LPS-induced HBD-2 mRNA expression via NF-kappaB is, at least in part, dependent on PKC, p38 MAPK, JNK, and protein tyrosine kinase status, but appears to be independent on PKA, ERK and ROS in HCE cells. Taken together, there may be more than one signaling pathways that lead to LPS-induced up-regulation of HBD-2 mRNA expression in HCE cells.
