A man with only yellowing of the skin and eye sclera was diagnosed with clonorchiasis, which rarely manifested jaundice as the initial symptom. However, because of a lack of evidence for a diagnostic gold standard, the time until definitive diagnosis was more than a week. The diagnostic process relied on inquiring about the patient's history, including the place of residence, dietary habits, and symptoms, as well as on serological findings, an imaging examination, and pathological findings. MRCP and CT results showed mild dilatation of intrahepatic ducts and increased periductal echogenicity. The eggs were ultimately found in stool by water sedimentation method after the negative report through direct smear. DNA sequencing of PCR production of the eggs demonstrated 98-100% homology with ITS2 of Clonorchis sinensis. After anti-parasite medical treatment, the patient's symptoms were gradually relieved. Throughout the diagnostic procedure, besides routine examinations, the sedimentation method or concentration method could be used as a sensitive way for both light and heavy C. sinensis infection in the definite diagnosis.
To determine the status of infection caused by intestinal parasites among children and adolescents living in Legaspi city, the Philippines, we performed a small survey by fecal examination for helminth ova and protozoan cysts with formalin-ether concentration method. Of the 64 examinees, the infection rate was 78.1%. The infection rates of primary school children, preschool children and adolescents were 95.5%, 64.7% and 87.5%, respectively. The infection rate in urban areas was 56%, and 92.3% in rural areas. The infection rates were 51% with Trichuris trichiura, 40% with Ascaris lumbricoides, 23.4% with hookworm, 15.6% with Iodamoeba butschlii, 14.1% with Endolinax nana, 9.4% with Entamoeba coli and 7.8% with Giardia lamblia. There were 33 cases with multiple infection (51.6%). Mixed infection with more than 3 parasites was observed in 15 cases, all of them being children and adolescents living in rural areas. By this survey, it was conjectured that helminthic infection is prevalent among children and adolescents in Legaspi, Philippines.

This study provides an application of datamining approach to CQI(Continuous Quality Improvement) using the discharge summary. First, we found a process variation in hospital infection rate by SPC (Statistical Process Control) technique. Second, importance of factors influencing hospital infection was inferred through the decision tree analysis which is a classification method in data-mining approach. The most important factor was surgery followed by comorbidity and length of operation. Comorbidity was further divided into age and principal diagnosis and the length of operation was further divided into age and chief complaint. 24 rules of hospital infection were generated by the decision tree analysis. Of these, 9 rules with predictive prover greater than 50% were suggested as guidelines for hospital infection control. The optimum range of target group in hospital infection control were Identified through the information gain summary. Association rule, which is another kind of datamining method, was performed to analyze the relationship between principal diagnosis and comorbidity. The confidence score, which measures the decree of association, between urinary tract infection and causal bacillus was the highest, followed by the score between postoperative wound disruption find postoperative wound infection. This study demonstrated how datamining approach could be used to provide information to support prospective surveillance of hospital infection. The datamining technique can also be applied to various areas fur CQI using other hospital databases.
This survey was undertaken to identify knowledge and performance level of MRSA infection control among medium and small hospital nurses. The subjects of the study were 261 medium and small hospital nurses. The collected data were analyzed by using SPSS WIN 18.0. The total mean values of the knowledge and performance on the MRSA infection control were $9.51{\pm}1.67$ and $2.26{\pm}.47$ respectively. the Knowledge about the general characteristics according to work department, MRSA infection control department presence, MRSA infection control guidelines presence, MRSA infection control education experience, MRSA infection control education method according to the statistically significant differences were observed. The performance about general characteristics according to age, work experience, work department, MRSA infection control department presence, MRSA infection control guidelines presence, MRSA infection control education experience and MRSA infection control education methods according to the statistically significant differences were observed. It is having sufficient various facilities, to enhance nurses knowledge about management of MRSA infection. If the continuous education of professional infection control is offered, it contributes to protect MRSA infection in the medium and small hospitals.
Purpose: The purpose of this study was to identify the influence of Vancomycin-resistant enterococcus (VRE) knowledge and awareness with VRE infection control in compliance with VRE infection control among nurses in intensive care units. Method: Participants (N=154) were recruited in B city from August 2007 to October 2007. Data were analyzed with SPSS PC+. Result: The degree of VRE knowledge of the participants was 12.41 out of the total score, 17; that of awareness with VRE infection control was 3.87 out of the total score, 4; that of compliance with VRE infection control 3.75 out of the perfect score, 4. A significantly positive relationship between awareness of VRE infection control and compliance with VRE infection control has been observed. Awareness with VRE infection control and type of intensive care unitpredicted 21.1% of the variance in compliance with VRE infection control. Conclusion: The study indicated that awareness with VRE infection control has the most important impact on the compliance with VRE infection control for the participants. Based on the finding, a suggestion is made to continue the research on VRE knowledge and nosocomical infection on the subject of nurse and nurse managers who are responsible for infection control in a medical institution.
To investigate the swine parasitic infection rate, we performed centrifugal floatation method and sedimentation method between Jan. 1989. and Dec. 1989. This results are shown as follows. 1. The numbers of infection were 593 pigs in 1080, shown 54.9% of infection rate. 2. In this survey, eight species of swine parasite were detected. The percentage of Balantidium coli was 44.5, revealed hightest level. There were 14.5% in Ascaris suum and 11.8% in Oesophagostomum SP respectively. 3. In this survey, there was high rate(86.0%) of parasitic infection in the pig raised at sawdust fermantation house. This results suggest that pig maybe liable to infect parasite.

Forty-eight spring barley genotypes were evaluated for deoxynivalenol (DON) concentration under natural infection across 5 years at Harrington, Prince Edward Island. These genotypes were also evaluated for Fusarium head blight (FHB) severity and DON concentration under field nurseries with artificial inoculation of Fusarium graminearum by the grain spawn method across 2 years at Ottawa, Ontario, and one year at Hangzhou, China. Additionally, these genotypes were also evaluated for FHB severity under greenhouse conditions with artificial inoculation of F. graminearum by conidial suspension spray method across 3 years at Ottawa, Ontario. The objective of the study was to investigate if reactions of barley genotypes to artificial FHB inoculation correlate with reactions to natural FHB infection. DON concentration under natural infection was positively correlated with DON concentration (r = 0.47, P < 0.01) and FHB incidence (r = 0.56, P < 0.01) in the artificially inoculated nursery with grain spawn method. Therefore, the grain spawn method can be used to effectively screen for low DON. FHB severity, generated from greenhouse spray, however, was not correlated with DON concentration (r = 0.12, P > 0.05) under natural infection and it was not correlated with DON concentration (r = -0.23, P > 0.05) and FHB incidence (r = 0.19, P > 0.05) in the artificially inoculated nursery with grain spawn method. FHB severity, DON concentration, and yield were affected by year, genotype, and the genotype × year interaction. The effectiveness of greenhouse spray inoculation for indirect selection for low DON concentration requires further studies. Nine of the 48 genotypes were found to contain low DON under natural infection. Island barley had low DON and also had high yield.
Purpose: This study was to assess the degree of infection prevention behaviors at home, and a relationship between those behaviors and barrier factors among cancer patients undergoing chemotherapy. Method: The data were collected from 92 cancer patients who were undergoing chemotherapy with more than two kinds of immunosuppressive agents at G university hospital in J city from February 17 to April 4, 2003. The instruments were the infection prevention behavior scale developed by researchers and the barrier factor scale by Gu et al. (2003). The data were analysed using mean, standard deviation, t-test, ANOVA, and Pearson's correlation coefficient by SPSS program. Results: The mean score of the behaviors for infection prevention was 2.61 of 4. The highest score was on the subscale 'rest and exercise', and the lowest score was on the subscale 'monitoring sign and symptom of infection'. And a negative correlation(r= -.208, p= .023) was found between infection prevention behaviors and barrier factors. The barriers correlated to infection prevention behaviors were mainly 'no habits' and 'no interest'. Conclusion: It seems that the degree of the behaviors for infection prevention was not performed enough to prevent infection among cancer patients. And there was negative relationship between infection prevention behaviors and barriers. We suggest to develop a nursing intervention program to enhance infection prevention behaviors through reducing the barrier factors.
Purpose: The purpose of this study was to identify the relationship between empowerment and performance of infection control by emergency department nurses. Method: Participants were 190 nurses working in emergency departments in 14 hospitals located in Busan. Descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficients with SPSS PC+ WIN 12.0 were used to analyze the data. Results: There were significant differences in empowerment by years in ED (emergency departments) and position. There was a significant differences in performance of infection control by position. There were significant differences in empowerment by infection control-related characteristics and by regular conference for infection control. There was a significant and positive relationship between empowerment and performance of infection control in ED nurses. Conclusion: The results of this study indicate that improvement in the level of ED nurse's empowerment would lead to an increase in the performances of infection control.
This survey was undertaken to evaluate the status of clonorchiasis in Chang-gok Myun, Hong-Seong Gun adjacent to Yedang reservoir from Sept., 1980 to Oct., 1981. A total of 550 subjects (male 318, and female 232) were examined by cellophane-thick smear technique and formalin-ether method. In order to identify the intensity of the Clonorchis sinensis infection, Stoll's egg dilution counting method was also applied to the C. sinensis positive cases. The following results were obtained in this survey; 1. In the examination of 550 subjects, Clonorchis sinensis eggs were found in 167 cases (30.4%). Male subjects showed 43.4% positive rates and female represented 12.5%. 2. The highest prevalence rate of Clonorchis sinensis was found in 40~49 year group in male (64.2%) and 30~39 year group in female (22.0%), although 14.3%~16.7% positive rates were found in young aged group. 3. Mean E.P.G. of Clonorchis sinensis infected cases were 6,148, showing 7,533 in male and 5,193 in female. 4. The degree of intensity of Clonorchis sinensis infection by E.P.G. count was distributed as 30.4% in light infection (1~999), 45.7% in moderate infection (1,000~29,999) and 5.8% in very heavy infection (over 30,000) in male. Female showed 48.3% in light, 37.9% in moderate, 10.3%. in heavy and 3.5% in very heavy infection. 5. Other helminthic infection rate was 15.6% in Ascaris lumbricoides infection, 15.1% in Trichuris trichiura infection and 4.4% of male subjects showed eggs of Taenia species.
