PURPOSE: To analyze hemodynamic parameters of electrical bioimpedance on increased blood pressure induced by pneumoperitoneum and compare hemodynamic effects of propofol and isoflurane during laparoscopic cholecystectomy. METHODS: Systemic vascular resistance index(SVRI), index of contractility(IC), end diastolic index(EDI), mean arterial pressure(MAP) and heart rate(HR) were measured after anesthetic induction, 5, 10, 15 and 30 minutes after CO2 insufflation and after CO2 removal. RESULTS: In isoflurane group, MAP, IC, SVRI were increased but EDI was decreased after induction of pneumoperitoneum. In propofol group, MAP, SVRI were increased but IC was decreased after induction of pneumoperitoneum. HR was not changed during operartion. CONCLUSION: After induction of pneumoperitoneum, MAP is increased by increased IC and SVRI in isoflurane. In case of propofol, the MAP is increased by increased SVRI. It seems that increased transmural pressure of lymphatics and splanchnic vasculatures rather than sympathetic stimulation increases SVRI after pneumoperitoneum.

PURPOSE: The mortality and morbidity rate after pancreaticoduodenectomy (PD) is still high, although the operative techniques and skills and the perioperative care has been improved. The incidence of PD for benign disease is 5~20%. The aim of this study is to determine the factors that differentiate between the benign group and the malignant group by comparing the clinical manifestations, and we studied the safety of performing PD for benign diseases by observing the early and late postoperative complications. METHODS: We retrospectively studied 124 patients who had been diagnosed with benign or malignant pancreatic diseases and who underwent PD between April 1995 and December 2005. We divided the patients into two groups, i.e., the benign group (20) and the malignant group (104), to compare their clinical characteristics and postoperative outcomes. Result: Chronic pancreatitis was the most common disease (35%) in the benign group and distal CBD cancer was the most common disease (40.4%) in the malignant group. Jaundice, weight loss, and elevation of CA 19-9 were more frequent in the malignant group than in the benign group (p<0.05). There were no statistical differences in the mortality rate (10.0% vs 6.7%), reoperation rate (5.0% vs 4.8%), hospital stays (27.1 days vs 24.0 days), early complications (30.0% vs 44.6%) and late complications (22.2% vs 26.4%) between the two groups. There were no mortality and newly developed malignancy during 33.4 months of follow-up period in benign group. CONCLUSION: On the preoperative evaluation, jaundice, weight loss, and elevation of CA 19-9 were more frequent in the malignant group. The postoperative early and late complications showed no difference between the two groups and complication rate was generally favorable. Thus, PD can be performed safely for benign diseases that cannot be treated in a conservative fashion and also for other clinically suspicious malignant diseases.

Parkinsonism is not commonly associated with intracranial tumors. The most common brain tumor causing parkinsonism is meningiomas. We are presenting two cases of meningiomas whose major manifestations included parkinsonism. In one, parkinsonian symptoms initially partially responded to L-dopa and bromocriptine. A CT scan taken for a stroke-like episode revealed a meningioma of left frontal convexity. After neurological sequelae of CO poisoning, the patient poorly responded to antiparkinsonian drugs. Surgical treatment of meningioma did not result in satisfactory control of extrapyramidal symptoms. In the other with a parasagittal meningioma, parkinsonian symptoms were postoperatiYely improved. Because no curative treatment is available for the majority of parkinsonian patients, early detection of an underlying neoplasm may result in a most rewarding outcome. It would be desirable to perform CT or MRI in cases of parkinsonism with other associated neurological manifestation. Unilaterality of parkinsonian symptoms may also be indication.

Paraneoplastic neurologic syndrome is a group of assorted disorders resulting from damage to the nervous system in cancer, remote from primary site, and not related to metastasis, infection, or metabolic disorder associated with cancer. Patient with small cell lung cancer sometimes shows various neurological syndromes, but patient with non-small cell lung cancer rarely shows neurologic syndromes and few antineuronal antibodies have been found. Here, we report a case of 53-year-old male patient who developed ptosis and extraocular muscular limitation of left eye due to third and forth cranial nerve palsy in non-small cell lung cancer without brain metastasis. These neurologic symptoms improved after lobectomy without any other treatment immunotherapy.

Abdominal wall leakage of dialysate in continuous ambulatory peritoneal dialysis (CAPD) patients is uncommon complication. We experienced one case of abdominal wall leakage in CAPD patient confirmed by CT peritoneography. She complained weight gain, decreased ultrafiltration volume, and localized abdominal wall edema without clinical evidence of hernia. CT peritoneography of the abdomen showed leakage of contrast dye from the site of insertion of the CAPD catheter into the anterior abdominal wall. The dialysate was completely drained and CAPD was discontinued. She was switched temporally to hemodialysis and abdominal wall edema disappeared. When CAPD was restarted seven days later, the edema appeared. After CAPD catheter was removed and reinserted at the opposite site, she returned to CAPD without leakage.

Pulmonary thromboembolism (PTE) originating from a renal vein thrombosis (RVT) is very rare, especially in relatively healthy young women. The patient described herein presented with a syncope-associated massive PTE. She was previously healthy, except for termination of an ectopic pregnancy with methotrexate 4 months before. The only medication she was taking was an oral contraceptive (OC), which was started 3 months before the PTE. She had no family history of venous thromboembolism (VTE) or any other underlying risk factors. We report the case of a woman who had a PTE originating from a RVT associated with OC use after an ectopic pregnancy.

PURPOSE: The surgical treatment of gastric cancer that invades adjacent organs is a radical gastrectomy with combined resection including the adjacent organs or a palliative operation by performing either a gastrojejunostomy or gastrectomy. However, since it is impossible to determine the exact stage of the cancer, either T or N, in the case of palliative surgery, it is inappropriate to predict patient prognosis. This study analyzes the prognoses for patients whose final TNM stages are determined by a combined resection performed due to macroscopical infiltration into the adjacent organs. MATERIALS AND METHODS: Of 2,452 patients that underwent surgery for gastric cancer at our hospital from 1983 to 2002, we evaluated 102 patients where a combined resection was performed because direct infiltration into the adjacent organs was discovered. RESULTS: Univariate analysis showed that the survival rate differed by the depth of invasion into the gastric walls, the degree of lymph node metastasis, distant metastasis, pathological TNM stage, surgical curability, the location of tumor, and histological differentiation. By multivariate analysis, it was found that the surgical curability, the location of the tumor and the degree of lymph node metastasis were independent prognostic factors. CONCLUSION: It is suggested that even when infiltration into adjacent organs is suspected, radical surgery should be performed as to allow a prediction of prognosis through an exact determination of disease stage, and to improve the survival rate.

BACKGROUND: It is thought that computer familiarity has increased significantly since 2004 as well as the use of computers. This study aimed to evaluate the effects of computer familiarity and types of keyboard and computer on the performance of the Korean computerized neurobehavioral test (KCNT), and to identify which parameters of KCNT were affected by aforementioned factors. METHODS: A total of 85 subjects were classified into three groups of computer familiarity by Korean typing speed. Their age, gender and the level of education were also collected. The parameters of KCNT included simple reaction time, choice reaction time, addition, symbol digit, and finger tapping speed. The test was conducted using three types of computers: a laptop computer, a laptop computer with a simplified keyboard, and a desktop computer with a simplified keyboard. RESULTS: Parameters including the simple reaction time, choice reaction time, addition, and symbol digit, and the finger tapping speed of non-dominant hand showed no significant differences in the results among the three groups by computer familiarity after age and educational years were controlled as covariates. The mean reaction time of the simple reaction time and the choice reaction time with a simplified keyboard was significantly shorter compared to that with a typical keyboard. With regard to type of computer, the mean reaction time of the simple reaction time and the choice reaction time was significantly reduced when performed with the desktop computer with a simplified keyboard. CONCLUSIONS: Unlike previous study results, the choice reaction time, the addition, and the finger tapping speed of dominant hand were the only parameters affected by the computer familiarity. Both the type of keyboard and the type of computer significantly influenced the simple reaction time and the choice reaction time. Therefore, it is recommended to use a desktop computer with a simplified keyboard for such parameters.

A 63 year-old woman visited our hospital with a palpable chest wall mass in the infrascapular region. We performed excision of the mass. The mass was histolocally diagnosed as elastofibroma. Elastofibroma is characterized by the proliferation of fibrous tissue with elastin. It is a relatively slow growing benign soft tissue tumor and it is most often found in the infrascapular region. We have experienced a cases of this rare disease and we report on it together with a review of the relevant literature.
