PURPOSE: The purpose of this study was to identify the influence of the ego-resilience and social support on the depression among hospital nurses. METHODS: The subjects of this study were 369 nurses in a hospital. We used the self-reported questionnaire to assess the level of ego-resilience, social support and depression of hospital nurses. The data were analyzed using descriptive statistics, frequency, t-test, ANOVA and logistic regression. RESULTS: The mean scores of ego-resilience, social support and depression were 42.6, 28.3 and 14.1, respectively. When scores of ego-resilience and social support were high, the level of mild and major depression of subjects decreased. The influencing factors of depression level were the department of work, ego-resilience and social support. CONCLUSION: The findings suggest that developing programs to improve ego-resilience and social support might be useful. Further study is required to justify the scale on ego-resilience and social support.

PURPOSE: This study was to investigate the relationship between IBS and nurses' occupational stress. METHOD: We used the modified Rome III criteria to measure the relationship between IBS and nurses' occupational stress. This questionnaire is composed of 9 areas and 43 items related to the stress. We collected the data of 395 respondents from W hospital. The survey was done from July 10th to July 31th, 2009. RESULTS: The morbidity of IBS showed 24.3%. It was significantly influenced by night shift, and hospital visits and medication because of abdominal discomfort for the past 6 months. The causes of the nurses' occupational stress, which influenced the difference between IBS and non-IBS group, were "conflict with doctors" "difficulties in human relationships" "dealing with guardians and patients." The IBS group's stress was higher that of the non-IBS group. Also 96.9% of the IBS group and 79.3% of the non-IBS group responded there was relationship between IBS and nurses occupational stress. CONCLUSION: We found the relationship between IBS and nurses' occupational stress. And such stress could be reduced through the education about IBS.

PURPOSE: The purpose of this study was to identify the effects of the social support and ego-resilience on the nursing performance among hospital nurses. METHODS: The subjects of this study were 369 nurses in a senior general hospital. We used the self-reported questionnaire to assess the level of ego-resilience, social support and nursing performance of hospital nurses. The data were analyzed using descriptive statistics, frequency, t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression. RESULTS: This study showed the positive relationship between the social support and ego-resilience on tne the nursing performance of hospital nurses. The higher group of the social support and ego-resilience showed the more performance of hospital nurses. And, the influencing factors on the performance are age, ego-resilience, social support, night working days a month in the order. CONCLUSION: Further studies will be needed to promote the performance of nurse in hospital and policies to be develop to elevate the social support and ego-resilience of nurses.

We have analyzed 2,080 patients who were admitted to the ICU for intensive care during a period of 11 years from April, 1965, when the ICU was opened, to December, 1975. The results are as follows: l. In 11 years, the total number of patients was 2,080 which was 2.5% of 84,933 patients who were admitted to NMC. Among them, operative cases were 724 (35%) and nonoperative were 1, 356(65%). 2. Male patients were more than female Patients (1. 3: l. ) 3. In age groups, the 20 decade had the highest number. 4. The number of patients from Internal Medicine Dept, was highest. 5. Total occupied bed days were 7,497 and majority of patient were in less than 3. 6 days. 6. The patients from the medical department have gradually decreased, but from the surgical department they showed increased pattern. 7. Drug intoxication was the commonest disease among patients. 8. Total mortality rate was 45%, and the highest mortality rate occurred in 30-39 age group.

PURPOSE: Ampulla of Vater cancer has a more favorable prognosis and survival than other malignant periampullary tumors. The pathologic staging of ampulla of Vater carcinoma is a key determinant of the patient's prognosis. However, we have often encountered patients in whom the course of their disease differed substantially from what would be predicted based on their clinical staging, which highlights the need to consider additional predictive factors. We applied an immunohistochemical technique to examine the expression of Ki-67 and VEGF in radicallyresected ampulla of Vater carcinomas, and then compared the status of expression with several clinicopathologic factors. METHODS: Sixty-four patients who underwent curative resection for ampulla of Vater cancer between January 1992 and December 2006 at the Yonsei University College of Medicine were reviewed. The relationships between the expression of molecular markers and clinicopathologic factors were determined. RESULTS: There was no relationship between the clinicopathologic characteristics and the expression of molecular markers in patients with ampulla of Vater cancer. Among the clinicopathologic characteristics, lymph node metastasis was identified as an independent factor of survival after curative resection for ampulla of Vater carcinoma. CONCLUSION: Measurement of Ki-67 and VEGF in patients with ampulla of Vater carcinoma may have an important role in identifying the poor prognostic group.

PURPOSE: To plug the biopsy site in eight patients with coagulopathy who had undergone percutaneous liverbiopsy. To this end, gelfoam cartridge was used as a sealant. MATERIALS AND METHODS: Using an 18G Tru-Cut-typedisposible automated biopsy gun(Soo Ho Medi-tech, Seoul, Korea) and under US guidance, eight patients underwentpercutaneous liver biopsy. After the gun had fired, the biopsy specimen in the inner stylet was retrieved whilethe outer cannula was held in place ; the cannula was then used to plug the biopsy tracks with gelfoam, using twoor three cartridges. If bleeding occurred, this was controlled by the use of more gelfoam cartridges. RESULTS: Diagnostic target tissue was obtained in seven of the eight patients(87.5%). Hepatocellular carcinoma wasdiagnosed in five cases and metastatic cancer in two. Profuse bleeding was observed in one patient(12.5%) andresolved by gelfoam plugging. CONCLUSION: We believe that in patients with coagulopathy who are required toundergo liver biopsy plugging the liver biopsy track with gelfoam cartridge is a simple, safe and useful method.

PURPOSE: Attention deficit hyperactivity disorder (ADHD) has been known as psychiatric disorder in childhood associated with dopamine dysregulation. In present study, we investigated changes in dopamine transporter (DAT) density of the basal ganglias using I-123 N- (3-iodopropen-2-yl) -2-carbomethoxy-3beta- (4-chlorophenyl) tropane [I-123 IPT] SPECT in children with ADHD before and after methylphenidate treatment. MATERIALS AND METHOD: Nine drug-naive children with ADHD and seven normal children were included in the study. We performed brain SPECT two hours after the intravenous administration of I-123 IPT and made both quantitative and qualitative analyses using the obtained SPECT data, which were reconstructed for the assessment of specific/nonspecific DAT binding ratios in the basal ganglia. All children with ADHD reperformed [123I]IPT SPECT after treatment with methylphenidate (0.7mg/kg/d) during about 8 weeks. SPECT data reconstructed for the assessment of specific/nonspecific DAT binding ratio of the basal ganglia were compared between before and after treatment methylphenidate. We investigated correlation between the change of ADHD symptom severity assessed with ADHD rating scale-IV and specific/nonspecific DAT binding ratio of basal ganglia. RESULTS: Children with ADHD had a significantly greater specific/nonspecific DAT binding ratio of the basal ganglia comparing to normal children (Right: z = 2.057, p = 0.041; Left: z = 2.096, p = 0.032). Under treatment with methylphenidate in all children with ADHD, specific/nonspecific DAT binding ratio of both basal ganglia decreased significantly greater than before treatment with methylphenidate (Right: t = 3.239, p = 0.018; Left: t = 3.133, p = 0.020). However, no significant correlation between the change of ADHD symptom severity scores and specific/nonspecific DAT binding ratio of the basal ganglia were found. CONCLUSIONS: These findings support the complex dysregulation of the dopaminergic neurotransmitter system in children with ADHD.

Mood stabilizers and atypical antipsychotics are commonly combined for the treatment of bipolar mania. The aim of this study was to compare the effectiveness and tolerability of topiramate and divalproex in combination with risperidone for treating acute mania patients in a naturalistic treatment setting. Seventy-four patients who met the DSM-IV criteria for bipolar mania were enrolled in this study. In order to assess the efficacy and the extrapyramidal symptoms, the Young Mania Rating Scale (YMRS), Clinical Global Impression (CGI) and Simpson-Angus Rating Scale were measured at the baseline and at weeks 1, 3 and 6. From the baseline to the endpoint, the YMRS and CGI scores were reduced by 67.9% and 56.6% in the topiramate group. The YMRS and CGI scores were also reduced by 63.7% and 58.2% in the divalproex group. The weight and BMI increased significantly by 3.6% and 3.3% from the baseline to the endpoint in the divalproex group, while they decreased by 0.4% and 0.5%, respectively, with no significant difference in the topiramate group. There were no serious adverse events in either group. Topiramate is effective and tolerable for treating acute mania, and may also be a promising alternative to a weightgain liable mood stabilizer such as divalproex.

PURPOSE: Although laparoscopic surgery has become more popular, its technical difficulties have limited the applications of this technique to liver surgery. We report here on our experience with liver resection with perfoming laparoscopic assisted and DaVinci robot assisted hepatectomy. METHODS: We retrospectively evaluated 40 patients who underwent laparoscopic assisted and DaVinci robotic assisted hepatectomy at the Yonsei University Health System from January 2002 to January 2008. RESULTS: Thirty patients (75%) had malignancy and ten patients (15%) had benign disease. We performed Lt. hepatectomy (7.5%), wedge resection (17.5%), segmentectomy (30%) and Lt. lateral segmentectomy (45%). The rate of conversion to laparotomy was due to intraoperative bleeding was 10%. The complication and mortality rates were 7.5% and 0%, respectively CONCLUSION: Laparoscopic and DaVinci robot hepatectomy showed a reduced time to oral intake, a shortened hospital stay and a smaller incisional scar compared to open surgery. So, laparoscopic and DaVinci robot hepatectomy should be performed in selected patients as the postoperative status of the patients is better than that with performing open hepatectomy.

Polyethylene glycol (Colyte(R)) electrolyte lavage solution is widely used for bowel preparataion before colonoscopy and surgery. The minor complications associated with PEG solution, i.e., nausea and bloating have been reported on. However, major complications such as PEG electrolyte lavage solution-induced Mallory-Weiss tear, esophageal rupture, asystole and aspiration have rarely been reported on. Spontaneous rupture of the esophagus (Boerhaave's syndrome) is a very rare disease and it is often diagnosed late or it is misdiagnosed because of the atypical clinical symptoms. Its mortality increases proportionally to the time between esophageal rupture and treatment. It can cause a fatal outcome unless it is treated early. We authors report here on a case of spontaneous esophageal rupture after bowel preparation with polyethylene glycol.
