BACKGROUND: This study was purposed to identify the knowledge and performance level of the infection control guidelines and to improve their performance level of infection control for those nurses who care patients directly. METHODS: This study was based on the survey questionnaires about infection control guidelines with the total 626 nurses in Seoul and Kyunggi areas for the period between May 26, 2003 and July 14, 2003. RESULTS: The average knowledge level of infection control was 0.84 +/-0.07 (score range 0-1) and the average performance level of the infection control was 4.44+/-10.27 (score range 0-5). The correlation between knowledge and performance of the infection control showed positive correlation (r=.39; P<.001). The knowledge and performance level of the 'Prevention of the central catheter infection' were higher than other infection control guidelines. The performance levels of the 'Prevention of the surgical site infection' were lower than other infection control guidelines. The correlation between knowledge and performance of the 'Prevention of the nosocomial pneumonia' (r=.389; P<.001). 'Prevention of the urinary tract infection' (r=.325; P<.001), 'Prevention of the central catheter infection (r=.290; P<.001) and 'Intravascular infection control' (r=.446; P<.001) showed positive correlation. CONCLUSION: The study demonstrated that the nurses' knowledge and performance of infection control guidelines showed positive correlation. So the education on the infection control is required indispensably and it would contribute to reduce the hospital infection rate by performing the right treatment on the infection control with the basis of accurate knowledge.

Actinomycoces is a gram positive, anaerobic, branching and non-acid fast bacterium which is a normal habitant of the skin, oral cavity, tonsil and gastrointestinal tract and its human infection is rare. Pelvic actinomycoses is frequently caused by Actinomycoces israel-ii. It is chronic, progressive, and more suppurative than granulomatous disease, and the symptoms are usually persistent and gradual, therefore the misdiagnosis and improper trea-tment are not uncommon. Actinomycoses is generally classified as cervicofacial, abdominal and thoracic type ac- cording to the site of the primary infection. Many actinomycotic pelvic infections in women used intrauterine device with long du- ration were reported, in contrast, others suggest that actinomycoces developed opportunistic infection irrespective of intrauterine device presence. We have experienced 4 cases of pelvic actinomycoses, one case with IUD(Lippes' loop) in a 47 year old woman, the other case with abdominal wall ctinomycoses in a 34 year old woman, the third case without IUD in a 41 year old woman, the fourth case with IUD(Cu-7) in a 37 year old woman and reported them with a review of literature.

Coronary artery and valvular injuries after blunt chest trauma are an unusual condition. This diagnosis is very difficult to estabilish, but prompt diagnosis and proper management are important in life saving. We report one patient who develop left main coronary artery dissection, tricuspid insufficiency, mitral insufficiency and pericardial rupture following blunt chest trauma. One year ago, he had suffered a frontal impact in a traffic accident and recieved anti-tuberculosis medication for 10 months for chest discomfort. The correct diagnosis was confirmed noninvasively by transesophageal echocardiography and the patient was treated left main coronary artery dissection flap removal, mitral valve replacement, tricuspid valvuloplasty and repair of ruptured pericardium. The postoperative course was uneventful and the patient was fully recovered.

Ginseng root rot caused by Cylindrocarpon destructans is the most destructive disease of ginseng. Six different fungicides (thiophanate-methyl, benomyl, prochloraz, mancozeb, azoxystrobin, and iprodione) were selected to evaluate the inhibitory effect on the mycelial growth and conidial germination of C. destructans isolates. Benomyl and prochloraz were found to be the most effective fungicides in inhibiting mycelial growth of all tested isolates, showing 64.7% to 100% inhibition at a concentration of 10 µg/mL, whereas thiophanate-methyl was the least effective fungicide, showing less than 50% inhibition even at a higher concentration of 100 µg/mL. The tested fungicides exhibited less than 20% inhibition of conidium germination at concentrations of 0.01, 0.1, and 1 µg/mL. However, the inhibition effect of mancozeb on condium germination of C. destructans was significantly increased to 92% to 99% at a higher concentration of 100 µg/mL, while the others still showed no higher than 30% inhibition.

Surgery, anticoagulation therapy, pregnancy, and hormone treatments, such as bromocriptine, are well-characterized precipitating factors for pituitary apoplexy. However, whether cytotoxic chemotherapy for systemic cancer could cause pituitary apoplexy has not been investigated. Here, we present a case of a 41-year-old woman who developed a severe headache with decreased visual acuity after intravenous cytotoxic chemotherapy to treat metastatic breast cancer. Preoperative neuroimaging revealed pituitary adenoma with necrosis. Operative findings and pathologic examination concluded extensive necrosis with a small intratumoral hemorrhage in a pre-existing pituitary adenoma. We reviewed two additional previously published cases of pituitary apoplexy after systemic chemotherapy and suggest that cytotoxic chemotherapy may induce pituitary apoplexy.

Streptococcus salivarius meningitis is very uncommon, and most cases are iatrogenic, occurring after invasive procedures such as spinal anesthesia or lumbar puncture etc.. Post-traumatic occurrence of this infection is especially rare. A 20-year-old man with a previous history of skull base fracture was seen at the emergency department with signs of acute bacterial meningitis. The CSF had a few gram positive cocci with neutrophilic pleocytosis, which were identified as S. salivarius by the Vitek system (bioMerioux, Inc., Hazelwood, MO, USA), rapid ID 32 Strep (bioMerieux, Marcy-l'Etoile, France) and 16S rRNA sequencing. The microorganism showed intermediate resistance to penicillin (MIC=0.25 microg/mL) but was susceptible to cefotaxime (MIC=0.25 microg/mL) and vancomycin (MIC= 0.75 microg/mL). The patient was treated with ceftriaxone and vancomycin. He also had his CSF leakage repaired by an endoscopic approach. To our knowledge, this is the first case of S. salivarius meningitis reported in Korea.

OBJECTIVE: To determine the usefulness of perfusion MR imaging in assessing the histologic grade of cerebral gliomas. MATERIALS AND METHODS: In order to determine relative cerebral blood volume (rCBV), 22 patients with pathologically proven gliomas (9 glioblastomas, 9 anaplastic gliomas and 4 low-grade gliomas) underwent dynamic contrast-enhanced T2*-weighted and conventional T1- and T2-weighted imaging. rCBV maps were obtained by fitting a gamma-variate function to the contrast material concentration versus time curve. rCBV ratios between tumor and normal white matter (maximum rCBV of tumor / rCBV of contralateral white matter) were calcu-lated and compared between glioblastomas, anaplastic gliomas and low-grade gliomas. RESULTS: Mean rCBV ratios were 4.90'+/-1.01 for glioblastomas, 3.97'+/-0.56 for anaplastic gliomas and 1.75'+/-1.51 for low-grade gliomas, and were thus sig-nificantly different; p < .05 between glioblastomas and anaplastic gliomas, p <.05 between anaplastic gliomas and low-grade gliomas, p < .01 between glioblas-tomas and low-grade gliomas. The rCBV ratio cutoff value which permitted dis-crimination between high-grade (glioblastomas and anaplastic gliomas) and low-grade gliomas was 2.60, and the sensitivity and specificity of this value were 100% and 75%, respectively. CONCLUSION: Perfusion MR imaging is a useful and reliable technique for esti-mating the histologic grade of gliomas.

BACKGROUND: Lung cancer incidence is gradually leveling off in developed countries but is continuing to rise in Korea. Because of the rapid increasing in smoking prevalence among women and youngers, the lung cancer incidence is expected to increase within next three and four decades. The aims of the present study are to analyses the smoking habits in patients with lung cancer and to evaluate of the relative risk of smoking habits in patients with lung cancer. METHOD: The present investigation was hospital-based, case control study. It included data from 93 case subjects with lung cancer and 1132 controls with disease unrelated to smoking using smoking history questionnaire by direct personal interview. RESULT: Compared with non-smoker, those who smoked more than 50 years had an odds ratio for lung cancer of 8.8(1.8-20.7). The odds ratios was 8.5(3.5-20.7) for those whose total number of cigarettes per days exceeded 41 and 5.5(2.3-13.3) for men with started habitual smoking less than 20 years old. The risk was increased in men with more than 41 pack years of cigarette smoking(OR:5.5, 95% CI:2.6-11.9). Odds ratios associated with cigarette smoking were 2.5(1.1-5.8), 5.1(2.6-10.4) for exsmoker and current smoker, respectively and 2.2(1.0-4.6) for non-filter smoker with more than 16 years. CONCLUSION: There was a clear dose-response relationship between the risk of lung cancer and smoking. We conclude that smoking dose is important risk factor for lung cancer and smoking habits may be, also.

BACKGROUND: Topoisomerase II (TOPO II) is an enzyme that separates intertwined chromosomes during DNA synthesis by transiently breaking and joining DNA strands. The level of TOP II is one of the determinants of cellular sensitivity to anti-tumor drugs in non-Hodgkin's lymphoma patients. The alpha form of TOPO II has been recently used as a marker of cellular proliferation. High levels of TOPO IIalpha are expressed in aggressive and proliferative tumors. METHODS: This study was designed to evaluate the relationship between TOPO IIalpha expression and clinicopathological parameters including age, gender, the serum LDH level, the serum beta2-microglobulin level and stage, or expressions, of Ki-67, p53 and p27, in non-Hodgkin's lymphoma. We analyzed forty-one biopsied tissue specimens from patients with non-Hodgkin's lymphoma. RESULTS: The expression of TOPO IIalpha increased with the clinical stage and it was correlated with Ki-67 and p53 expressions. However, TOPO IIalpha expression did not have any significant correlation with age, gender, the serum LDH level, the serum 2-microglobulin level and the p27 expression. CONCLUSIONS: TOPO IIalpha expression is a useful marker of cellular proliferation and it may serve as a prognostic factor of a tumor's progression and aggressiveness in non-Hodgkin's lymphomas.
