This study set out to investigate dental hygiene students' perceptions and performance of dental clinic infection management of clinical training, thus helping to minimize nosocomial infection and providing basic data for infection management and action guidelines in development of curriculums and educational programs. A survey was taken with dental hygiene students that had experiences with clinical training at a four-year university in Gyeongbuk. The findings show that many of the students had experiences with education about the prevention of infection. There were differences in their performance of infection prevention management among the sites of clinical training with university and general hospitals recording a high level of performance. These findings raise a need to make guidelines for infection management, distribute them to sites of clinical training, and manage them through the staff during clinical training. The schools need to run educational program for infection management in relation to clinical training and establish a systematic institution.

The aim of this study was to investigate the peculiarity of awareness, performance and empowerment of RTs and to find out the relationship between the levels of awareness, performance and empowerment and nosocomial infection control. A total of 84 RTs, which were working at C University Hospital in Gwangju city, were participated in this survey study. A final questionnaire consisted of total 80 items including the general characteristics(10), nosocomial infection(10), awareness level(24), performance level of the prevention of nosocomial infection(24) and empowerment scale(12). The levels of awareness and performance for prevention of nosocomial infection was significantly higher in senior RTs (p<0.05). The response about the content of 'no performance of infection control were excessive work(42.9%), lack of knowledge(17.8%) and insufficiency of time(16.7%), respectively. The association among awareness level, performance level and empowerment score for the prevention of nosocomial infection, it showed positive correlations as follows: awareness vs. performance level (Pearson's coefficient ${\gamma}=0.476$), awareness vs. empowerment (${\gamma}=0.276$) and performance vs. empowerment (${\gamma}=0.459$) (p<0.05). The factor that effected on performance was empowerment (p<0.05).

Anemia commonly occurs in kidney transplantation (KT) recipients. Many factors such as viral infection, bleeding, erythropoietin deficiency, and immunosuppressants are the causes of chronic anemia in KT recipients. We report 2 cases who developed severe anemia caused by parvovirus B19 infection and were successfully treated with intravenous immunoglobulin in pediatric KT recipients.

The pathogenic potential of Acnnthamoebc strains was evaluated by experimental infection of murine AIDS (MAIDS) model. C57BL/6 mice were induced to immunocompromized state by intraperitoneal injection of LP-BM5 MuLV and revealed the typical splenomegalty and Iymphatic enlargement of axillar and inguinal regios on necropsy 4 weeks after viral infection. Although there was no significant difference in the mortality rate of MAIDS mouse according to the culture temperature, it was very different in the mortality rate from strain to strain of Accnthnmoebc. A. henIHi OC-3A strain isolated from the brain of a GAE patient showed !he highest mortality rate and A. culbertsoni A-1 strain from tissue culture was the second. KA/S3 and KA/S2 strains isolated from soil revealed very low virulence. The mice infected by intranasal inoculation of Acanthnmoebc showed relatively chronic course than intravenous inoculation. The gross findings of lungs and brains from infected mice were variable among mice. On the microscopic observations, the lungs showed much more severe inflammation and necrosis than the brains microscopically. This MAIDS model would be useful to study the opportunistic protozoan infections of AIDS patients. In the light of these results. the pathogenic potential and the virulence of Acnnthamoebo may be determined genetically.

On MRI, abnormal signals of the intervertebral disc, destruction of the upper and lower vertebral body endplate around the disc, and bone marrow edema around the endplate are considered typical findings of infectious spondylitis. These findings can also appear in various non-infectious spinal diseases, such as degenerative changes, acute Schmorl's node, spondyloarthropathy, synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO), chronic recurrent multifocal osteomyelitis, and calcium pyrophosphate dihydrate crystal deposition disease. The imaging findings of infectious spondylitis that can be differentiated from these non-infectious spinal diseases on MRI are high signal intensity and abscess of the disc space, an abscess in the paraspinal soft tissue, and the loss of the linear low signal intensity on T1-weighted images of the bony endplate. However, these differentiation points do not always apply since there are many similarities in the imaging findings of infectious and non-infectious diseases. Therefore, for an accurate diagnosis, it is important to know the imaging characteristics related to the pathophysiology of not only infectious spondylitis but also non-infectious spinal diseases, which requires differentiation from infection.

Purpose: Urinary tract infections (UTIs) are the most common serious bacterial infections in young infants. Lumbar puncture (LP) has been used to diagnose coexisting meningitis in infants under 90 days of age with suspected UTI in many hospitals. However, the incidence of bacterial meningitis associated with UTIs is low. We aimed to describe the prevalence of concomitant bacterial meningitis in young infants with UTIs. Methods: The medical records of infants with the first episode of UTI admitted to the Chung-Ang University Hospital from January 2010 to December 2019 were retrospectively reviewed. Infants aged < 90 days who underwent LP with initial evaluation were included. Demographic and clinical features, laboratory findings, and imaging findings were collected and analyzed. Results: Eighty-six infants with UTIs were enrolled in the study. The median age was 61.5 days (interquartile range, 42.3-73.8 days) and boys (90.7%) were predominant. Escherichia coli was the most common pathogen (n=80, 93.0%) and followed by Klebsiella species (n=5, 5.8%). Fifteen (18.1%) specimens produced extended spectrum β-lactamase (ESBL). Five (5.8%) infants had positive blood culture results. Seven (8.1%) infants showed pleocytosis in the cerebrospinal fluid, but none had coexisting bacterial meningitis. Twenty-four (30.8%) infants showed renal dilatation or hydronephrosis on ultrasonography. Dimercaptosuccinic acid (DMSA) scans revealed cortical defects in 17 (21.3%) infants while voiding cystourethrography revealed vesicoureteral reflux in 6 (46.2%) infants. Conclusion: Co-existing bacterial meningitis was not observed in young infants with UTIs. LP could not be routinely performed considering the clinical condition of <90 days old UTI patients.

This study aims to identify the awareness and performance level of hospital infection control in medical technicians working in small and medium-sized hospitals. The experiment was conducted in 235 medical technicians (medical laboratory technologist, radiological technologist, and physical therapist), and for statistical processing, SPSS Ver.23.0 was used to conduct mean and standard deviation, analysis of variance, and regression analysis. As a result, it was found that the major cause of improper infection control was lack of experts ($3.17{\pm}1.18$) and performance level was statistically significantly lower than awareness of infection control. "I took no measures after infection accident" was responded the highest at 40.0%(94 persons), and in "I reported to the head of department after disinfection, examination, and/or vaccination," the standardized regression coefficient ${\beta}$ was -0.265, p=0.025, which suggested that there was a significant negative (-) impact. Infection control level showed a significant positive correlation with training and infection control instructions. Therefore, it was found that medical technicians in small and medium-sized hospitals required high skilled manpower in infection control, training, infection control instructions, etc. Through this study, more effective infection control is considered to be possible.

The purpose of the study is to investigate infection management status of long term care hospitals and infection prevention knowledge of caregivers. This is descriptive study to investigate the factors affecting caregivers' infection control performance in long term care hospitals. The data collection period was from August, 2018, and a total of 197 caregivers from 8 long term care hospitals. The data analysis were done Win SPSS 20.0 with t-test, ANOVA, pearson's correlation coefficient, and hierarchical multiple regression analysis. Infection prevention knowledge was positively correlated with infection control performance (p=<.001). The factors influencing performance in a long term care hospital caregivers were over seventy years old (t=2.50, p=.013), eight-hour working time (t=-2.62, p=.010), nursing staffing First grades (t=2.48, p=.014), and infection prevention knowledge (t=2.96 p=.003), which explained 12.9% (F=6.70 p<.001). In summary, we recommend to develop infection education interventions to improve caregivers' infection control performance in long term care hospitals and to improve of the function in long term care hospitals.
