This study was done to identify the relationships between nursing practice stress and stress coping for the nursing students in Korea. Data were collected at 2 universities located in C city in Korea. Participants were 160 nursing students. Data were analyzed by SPSS 18.0 using descriptive statistics and Pearson's correlation coefficient. Nursing practice stress was $2.72{\pm}6.2$. Stress coping was $2.60{\pm}0.37$. Stress was correlated with wishful thinking coping strategy when doing orientation (r=0.32, p<0.01), conference(r=0.52, p<0.01), homework(r=0.29, p<0.01). Stress for practice exam was correlated with problem focused coping strategy(r=0.31, p<0.05). Stress was correlated with positive view coping strategy when face nurse(r=0.31, p<0.01) or interpersonal relations(r=0.35, p<0.01). Stress related to practice environment and class was correlated with indifference (r=0.26, p<0.01) and tension relieve strategy (r=0.28, p<0.01). There's no stress when they meet or serve direct care to patients. Students managed the stress by showing active coping pattern. It is considered that the experience gave students an excellent capacity to cope with stress. Since the degree of stress and coping pattern can differ from adaptability of situation, a research of change in clinical training stress by seasonal clinical training and coping patter is proposed.

Purpose: Group A streptococcus (GAS) is a common pathogen in pediatric patients and often causes acute pharyngotonsillitis and skin and soft tissue infections. In addition, bacteremia with significant morbidity and mortality can also occur. This study was conducted to describe the clinical manifestations and treatment outcomes of pediatric GAS bacteremia patients in Korea. Methods: This was a single-center, retrospective study. From January 2000 to December 2016, pediatric patients aged ≤18 years with GAS bacteremia were studied. Clinical manifestations, underlying diseases, intensive care unit stay, and antibiotic susceptibility were evaluated. Results: During the study period, 19 patients had GAS bacteremia. Ten (53%) were male, and the median age was 7.4 years (range, 0.3-17.4 years). Fourteen (74%) had chronic underlying diseases. Five (26%) were immunocompromised (leukemia and chronic kidney disease). Eight (42%) had lymphatic or vascular malformations, of which seven had lesions with signs of inflammation. Three (16%) developed pneumonia, and two of them received ventilator care. The 30-day mortality rate was 6% (1/19), and the cause of death was bacteremic pneumonia. All GAS isolates were sensitive to penicillin. Fifteen (79%) were sensitive to both erythromycin and clindamycin. Conclusions: This study identified various clinical manifestations of GAS bacteremia. GAS should be considered as a potential pathogen that can cause bacteremia and result in a serious clinical course.

Background: The appropriate empirical antimicrobial choice in the treatment of community-acquired pneumonia (CAP) should be advocated by community-based information on the etiologic pathogens, their susceptibility to antimicrobials, clinical characteristics and outcomes. Jeju is a geographically isolated and identical region in Korea. However, there is no regional reference on adult CAP available. This study investigated the etiologic agents and clinical outcomes of adult patients diagnosed with CAP in Jeju, Korea, to help guide the empirical antimicrobial choice. Methods: A prospective observational study for one year in a referral hospital in Jeju, Korea. Patients diagnosed with CAP were enrolled with their clinical characteristics. Microbiological evaluations to identify the etiologic agents in the adult patients with CAP were performed with blood culture, expectorated sputum smear and culture, antibody tests for mycoplasma, chlamydophila, and antigen tests for legionella and pneumococcus. The clinical outcomes of the initial empirical treatment were analyzed. Results: Two hundred and three patients with mean age of 64 and 79 females were enrolled. Ten microbials from 90 cases (44.3%) were isolated and multiple isolates were confirmed in 30. Among the microbial isolates, S. pneumoniae (36.3%) was the most common, followed by M. pneumoniae (23.0%), C. pneumoniae (17.0%), S. aureus (9.6%) and P. aeruginosa (5.9%). The initial treatment failure (23.8%) was related to the isolation of polymicrobial pathogens, elevated inflammatory markers, and the presence of pleural effusion. Among the 30 isolates of S. pneumoniae, 16 (53.3%) were not susceptible to penicillin, and 19 isolates (63.3%) to erythromycin and clarithromycin. However, 29 isolates (96.7%) were susceptible to levofloxacin and ceftriaxone. Conclusion: S. pneumoniae, M. pneumoniae, S. aureus, and P. aeruginosa are frequent etiologic agents of adult CAP in Jeju, Korea. The clinical characteristics and antibiotic resistance should be considered when determining the initial empirical antimicrobial choice. Respiratory quinolone or ceftriaxone is recommended as an empirical antimicrobiotic in the treatment of adult CAP in Jeju, Korea.

Septic encephalopathy is defined as brain dysfunction secondary to sepsis. It occurs in septic patients as a manifestation of multi-organ dysfunction. Without evidence of intracranial infection, various extracranial infections causing severe sepsis may induce septic encephalopathy. We report a patient with septic encephalopathy complicating acute appendicitis. Initially, the patient presented with impaired mental state and raised liver enzymes.

Purpose : Glycogen storage disease type Ia(GSD Ia) is an autosomal recessive disorder caused by the deficiency of glucose-6-phosphatase(G6Pase). The aim of the study was to investigate the spectrum of G6Pase gene mutations and relationship between genotype and clinical findings in Korean patients with GSD Ia. Methods : Genomic DNA was extracted from peripheral leukocytes of 20 patients with GSD Ia. The five exons of G6Pase gene were amplified and PCR products were directly sequenced. The frequency of short stature, hypoglycemia, hypercholesterolemia, hyperuricemia, hypercalciuria, nephrocalcinosis and hepatic adenoma was compared between 727G>T homozygotes and 727G>T compound heterozygotes. Results : A total of 5 different mutations were identified. The most common mutation was the 727G>T with an allele frequency of 80%. All patients were either homozygous(12/20) or heterozygous(8/20) for the 727G>T mutation. G122D was found in 3 patients, P178A in 1, G222R in 2, and S339R in 2. There was no difference in the frequency of short stature, hypoglycemia, hypercholesterolemia, hyperuricemia, nephrocalcinosis, and hepatic adenoma between 727G>T homozygotes and heterozygotes. Conclusion : Diagnosis of GSD Ia can be based on clinical and biochemical abnormalities combined with mutation analysis instead of enzymatic diagnosis that requires liver biopsy. Homozygosity for the 727G>T does not seem to alter the disease phenotype as compared with the heterozygous state.

The purpose of this study was to investigate the distribution of Enterococci isolated from clinical specimens, and identify the aspect of antibiotic susceptibility and analyze the genetic difference by executing Rep-PCR over the strains resistant to aminoglycoside-typed antibiotics. From an assortment of the clinical specimens, 100 strains were isolated. The collection consisted of 49 strains of E. faecalis, 34 strains of E. faecium, 9 strains of E. avium, 4 strains of E. gallinarum, 3 strains of E. casseliflavus, and 1 strain of E. hirae. Ninety five were isolated from inpatients, and five strains were isolated from outpatient. Most of the E. faecalis and E. faecium were originated from urine, pus, and sputum. Most Enterococci showed 80% resistance to the cephalosprin-typed antibiotics. E. faecium showed the high resistance to all the antibiotic substances. One tenths of Enterococci showed the resistance to vancomycin. And also, most Enterococci showed the high resistance to amikacin and gentamicin as aminoglycoside-typed antibiotics. Genetic diversity of the resistant strains to aminoglycoside estimated using Rep-PCR was not significanty different.
