PURPOSE: This study was performed to investigate the effect of work environment on nursing performance and the effect of job satisfaction and empowerment on nurses performance in hemodialysis units. METHODS: Participants in this study were 206 nurses from 22 hemodialysis units in local clinics, general and university hospitals in two metropolitan areas. The work environment, nursing performance, job satisfaction and empowerment of the participants were measured using four self-report questionnaires. Data were analyzed using SPSS/WIN 18.0. RESULTS: Nursing performance correlated significantly with work environment, job satisfaction, and empowerment in the participants. Predictability of work environment for nursing performance was 28%. Job satisfaction and empowerment showed complete mediating effects, but not moderating effects in the relationship of work environment and nursing performance in the participants. CONCLUSION: Findings indicate that work environment is an important variable affecting nursing performance in nurses in hemodialysis units and that job satisfaction and empowerment are mediating variables in the relationship of work environment and nursing performance in nurses in hemodialysis units. Improvements in the work environment are needed to induce the high job satisfaction and empowerment that can lead to improvement of nursing performance.

PURPOSE: To investigate the relation of the gastric epithelial cell proliferation, apoptosis and genotypes of H. pylori in children. METHODS: Histologic grading by updated Sydney system, PCNA immunostaining, TUNEL method and the genotypes (cagA, picB and iceA) by PCR were performed in H. pylori positive (N=20) and negative (N=20) gastric biopsy specimens. RESULTS: PCNA index was significantly different between H. pylori positive children (77.4+/-13.12) and H. pylori negative children (52.3+/-12.20) (p=0.000). There were positive correlations between PCNA index and H. pylori density (r=0.624, p=0.000), polymorphonuclear neutrophil activity (r=0.460, p=0.005) and chronic inflammation (r=0.433, p=0.009). Apoptosis index of H. pylori positive children (0.70+/-0.411) was significantly higher than of H. pylori negative children (0.14+/-0.201) (p=0.000). Positive correlations between apoptosis index and H. pylori density (r=0.691, p=0.000), polymorphonuclear neutrophil activity (r=0.585, p=0.000) and chronic inflammation (r=0.535, p=0.001) were noted. As PCNA index increased, apoptosis index significantly increased (r=0.527, p=0.001). The positive rates of genotypes were cagA 90%, picB 75%, iceA1 60% and iceA2 15%, respectively. There were no significant correlations between the status of the genotypes and PCNA index, apoptosis index, the endoscopic findings and the histologic findings. CONCLUSION: PCNA index and apoptosis index in H. pylori positive children were higher than in H. pylori negative children but were not related to H. pylori genotypes. This study suggested that correlatively increased gastric epithelial cell proliferation and apoptosis are important to pathogenesis of H. pylori infection in children.

BACKGROUND: The APACHE scoring system of the Health Care Financing Administration (HCFA) has been being used for serious patients. The scoring system is composed of acute physiologic variables and chronic disease. METHODS: Among patients who underwent emergency operations from 1992 to 1997 because of gastrointestinal perforation, we analyzed 110 cases with five kinds of diseases: duodenal ulcer perforation, small bowel perforation, perforated appendicitis, gastric ulcer perforation and colon perforation. RESULTS: The results were as follows: 1) The preoperative APACHE II scores ranged from 0 to 21. The scores of 64 cases (60.9%) were from 0 to 5. 2) There were no death in case for which pre-peration APACHE II score was from 0 to 10, 25% of the mortality occurred in cases with scores from 11 to 15, 50% in those with scores from 16 to 20, and 100% in those with scores above 21. 3) The APACHE II score decreased continuously from the 3rd to the 7th postoperative day. 4) The preoperative APACHE II scores in gastric ulcer perforation patients were significantly higher than those in duodenal ulcer perforation patients. In the cases of gastric and duodenal ulcer perforations, the APACHE II scores in patients who underwent primary closure were higher than the scores in those who underwent a more definitive operation. 5) In death cases, all of their APACHE II scores were higher at the 3rd postoperative than at the 7th postoperative day, but their APACHE III scores continuously increased postoperatively. CONCLUSIONS: It is thought that the APACHE scoring system is more reliable than clinical experience in the classification of patients by operative risk and in estinating the result and giving a prognosis. Thus, the principle of treatment should be established by estinating patient's score before the operation. Careful preoperative management is necessary for patients with scores more than 10. Because patientswith scores more than 21 have very a high mortality, operative time and method must be carefully decided. The APACHE III scoring system seems to be more sensitive than the APACHE II scoring system in predicting deaths and further investigations and clinical applications should be performed.

PURPOSE: The purpose of this study was to determine the utility of serum prealbumin as a biochemical marker for nutritional adequacy in neonates. METHODS: From March 1998 to May 1999, 71 fullterm (54 AGA, 9 LGA, 8 SGA) and 46 preterm neonates were enrolled. The correlations among prealbumin, albumin, birth weight and gestational age were obtained. Serum concentrations of albumin and prealbumin according to calory and protein intake were also serially measured in 30 fullterm and 29 preterm neonates on days 0, 3 and 7 of life. RESULTS: Serum prealbumin concentrations at birth were 10.2+/-2.6mg/dL in fullterm AGA, 12.1+/-3.3mg/dL in fullterm LGA, 8.3+/-1.2mg/dL in fullterm SGA and 8.8+/-2.4mg/dL in preterm neonates. Serum prealbumin concentration was significantly correlated with birth weight, gestational age and serum albumin level (P<0.01). In the neonates, prealbumin concentrations on day 3 of life were significantly lower than initial concentrations, and then they rised on the day 7 of life (P< 0.05). Serial serum prealbumin level was significantly correlated with body weight, calory intake and protein intake (P<0.01). When caloric and protein intakes were higher than 100kcal/kg/d and 2g/kg/d, respectively, there were significant differences in the changes of prealbumin concentrations on days 0, 3, and 7 of life, compared with those in neonates with lower intake. CONCLUSION: Serum prealbumin concentration could be used in the early recognition of changes in nutritional state in neonates.

PURPOSE: The purpose of this study is to evaluate the knowledge and attitudes of oncology ward nurses toward cancer pain management and to find ways to improve the educational program for nurses. METHOD: A total of 209 nurses working at the oncology ward of three hospitals in Seoul and a Gyenggi Province. The survey instrument used was the 32-item scale for evaluating nurses knowledge and attitudes originally developed by McCaffery and Ferrell'(1990), that was by Kim'(1997). RESULTS: In terms of the nurses knowledge of pain management, the result showed that the nurses scored an average of 67.8 out of 100 for phamacokinetics of opioids, 84.8 for classification of analgesics, 60.1 for pain assessment, and 70.7 for drug administration. 18.2% of the nurses hesitate to inject the narcotic agent because of concerns regarding the drug's potential side effects. there was significant difference in the knowledge of pain management according to the general characteristics of pain in terms of the nurses age(p=.001), position (p=.016), years of experiences(p=.002), experience of cancer pain education(p=.001). CONCLUSION: The also showed that nurses working at cancer ward lack knowledge. It is important to provide intensive education to nurses about cancer pain management.

OBJECTIVE: To evaluate the relationship between postoperative sensory change on lower extremities and clinical factors associated with gynecologic operation. METHODS: We retrospectively reviewed 38 cases of patients with postoperative complaints of pain or dysthesis on lower extremities, especially anterolateral thigh from March 1993 through December 1999 at Gyeongsang National University Hospital, Department of Obstetrics and Gynecology. The electromyography (EMG) and nerve conduction velocity (NCV) were performed in all 38 patients. According to the result of EMG and NCV, patients were divided into control group (n=28) which in that with normal finding in electrodiagnosis and study group (n=10) who showed femoral cutaneous nerve injury in electrodiagnosis. Clinical characteristics (age, height, weight and operative history), operative methods, skin incisional method, operative time and postoperative diagnosis were reviewed in each group. RESULTS: There were significant differences in patient's body weight, height, skin incisional method and operative method between control and study group. Height was 152.5cm [150.3-155.6] in study group and 157.5cm [153.4-159.2] in control group (p-value = 0.020). Weight was 46.9kg [43.4-58.0] in study group and 57.0kg [54.4-58.1] in control group (p-value=0.004). Skin incisional method in study group was done by 6 cases (60%) of infraumbilical mid-line vertical incision and in control group by 5 cases (17.9%) (p-value = 0.019). In operative method, radical hysterectomy was 4 cases (40%) in study group and 2 cases (7.1%) in control group (p-value=0.031). But no correlation was observed in post-operative diagnosis, operative time, blood loss and transfusion between two groups. CONCLUSION: It was suggested that Lateral femoral cutaneous nerve was compressed by pelvic retractor during the gynecologic operation. Patient's body weight, height, skin incisional method and operative method may play a role of compressive factor on Lateral femoral cutaneous nerve, increasing Meralgia Paresthetica.

Colorectal carcinomas occur primarily in elderly people and are rare in children. Unlike adult colorectal carcinomas, the overall prognosis is very poor because of the usual delay in diagnosis and advanced stages at presentation or initial diagnosis, and a high incidence of aggressive tumor pathology such as mucinous adenocarcinoma. Colon cancer should not be excluded in children only based on age or barium enema results. Therefore, colonoscopy should be performed in pediatric patients with unexplained rectal bleeding and abdominal pain. We report a rare case of a child with a mucinous adenocarcinoma of the sigmoid colon in a 12-year-old boy, who presented with an abdominal mass and abdominal pain and review the medical literature.

BACKGROUND: This study investigated the association between the frequency of growth hormone receptor (GHR) exon 3 polymorphism (exon 3 deletion; d3-GHR) and metabolic factors in patients with acromegaly in Korea. METHODS: DNA was extracted from the peripheral blood of 30 unrelated patients with acromegaly. GHR genotypes were evaluated by polymerase chain reaction and correlated with demographic data and laboratory parameters. RESULTS: No patient had the d3/d3 genotype, while four (13.3%) had the d3/fl genotype, and 26 (86.7%) had the fl/fl genotype. Body mass index (BMI) in patients with the d3/fl genotype was significantly higher than in those with the fl/fl genotype (P=0.001). Age, gender, blood pressure, insulin-like growth factor-1, growth hormone, fasting plasma glucose, triglycerides, high density lipoprotein cholesterol, and low density lipoprotein cholesterol levels showed no significant differences between the two genotypes. CONCLUSION: The d3-GHR polymorphism may be associated with high BMI but not with other demographic characteristics or laboratory parameters.
