OBJECTIVE: To analyze incidence, indications, risk factors, complications, and neonatal outcomes of emergency postpartum hysterectomies performed at EulJi University Medical Center. METHODS: A retrospective study of all cases of postpartum hysterectomies between May. 1996 and Dec. 2000. was carried out. RESULTS: 37 cases of postpartum hysterectomies during this period were performed, for overall incidnce of 2.3 per 1000 deliveries. Incidence after vaginal delivery and cesarean section was 0.03% and 0.52% respectively. The rate of postpartum hysterectomy increased with increasing age and parity. The main indications were placental disorders(54.1%) including placenta previa and adherent placenta, uterine atony(37.8%), uterine myoma(5.4%) and uterine rupture(2.7%) in order. The relative risk of postpartum hysterectomy according to the risk factors was 97.6(95% confidence interval 52.17-184.06) for placental disorders, 16.3(95% confidence interval 4.94-52.31) for cesarean section and 2.4(95% confidence interval 1.21-4.76) for previous cesarean section. The mean amount of transfuion was 17.1 pints. Although no maternal mortality had occurred, 16 patients(43.2%) had complica-ions including respiratory complication(13.5%), hemorrhagic complication(10.8%), infection(8.1%) and urologic injury(8.1%). Regarding fetal outcome, 2 of 38 infants(1 case, twin) were stillborn (5.3%) and 10 infants(26.3%) were suffered from various illness including prematurity, sepsis, meningitis, and brain hemorrhage. CONCLUSION: The data identifies placental disorders are the leading cause of postpartum hysterectomy. Although postpartum hysterectomy is a necessary life-saving operation, maternal morbidity remained high.

There are limited data evaluating the relationship between influenza treatment and hospitalization duration. Our purpose assessed the association between different treatments and hospital stay among Korean pediatric influenza patients. Total 770 children < or = 15 yr-of-age hospitalized with community-acquired laboratory-confirmed influenza at three large urban tertiary care hospitals were identified through a retrospective medical chart review. Demographic, clinical, and cost data were extracted and a multivariable linear regression model was used to assess the associations between influenza treatment types and hospital stay. Overall, there were 81% of the patients hospitalized with laboratory-confirmed influenza who received antibiotic monotherapy whereas only 4% of the patients received oseltamivir monotherapy. The mean treatment-related charges for hospitalizations treated with antibiotics, alone or with oseltamivir, were significantly higher than those treated with oseltamivir-only (P < 0.001). Influenza patients treated with antibiotics-only and antibiotics/oseltamivir combination therapy showed 44.9% and 28.2%, respectively, longer duration of hospitalization compared to those treated with oseltamivir-only. Patients treated with antibiotics, alone or combined with oseltamivir, were associated with longer hospitalization and significantly higher medical charges, compared to patients treated with oseltamivir alone. In Korea, there is a need for more judicious use of antibiotics, appropriate use of influenza rapid testing.

OBJECTIVE: The purpose of this study was to investigate the impact of specific behavioral problems on the health-related quality of life (HRQOL) in children and adolescents with epilepsy. METHODS: Children and adolescents with epilepsy (n=92; age range=6–17 years) and their mothers completed questionnaires about behavioral problems, HRQOL, socio-demographics, and epilepsy-related variables. To determine significant predictor variables of the HRQOL, the stepwise regression analyses and partial correlations were performed to adjust for other behavioral problems and covariates. RESULTS: The analyses revealed that an increase in social behavioral problems and delinquent behavior was associated with a decrease in the HRQOL. Lower levels of maternal education and the number of antiepileptic drugs were also associated with a decline in the HRQOL; the HRQOL and social behavioral problems remained significantly correlated after adjusting for maternal education level, number of antiepileptic drugs, and non-social behavioral problems. CONCLUSION: Parents and practitioners should provide intervention if behavioral problems, particularly social behavioral problems, are observed in children or adolescents with epilepsy.

Purpose: This year 2020 marks the 50th anniversary of the founding of the Korean Society of Nursing Science (KSNS). This study wasaimed to explore development of caring and describe the 50 years of history of KSNS within the sociocultural context of Korea regardingacademic footsteps, meanings, and implications for the future. Methods: This study used a historical research methodology using a literaturereview and bibliometric analysis. Relevant literature was reviewed and the published abstracts in the Journal of Korean Academy ofNursing (JKAN) were analyzed using VOSviewer. Results: Birth control and family planning in the 1970s was the main research topic. In the1980s, the development of nursing concepts, theories, and philosophies was the mission of KSNS to extend the disciplinary boundary. In the1990s, the progress of KSNS to become one of the woman-dominant healthcare professionals was the mission in the given period. Expandingthe frontiers of KSNS to the extent of global standards was the undertaking of the nursing scholars in the 2000s. Lastly, in the 2010s,the quality and quantity improvement of KSNS and JKAN is expected to make our future even prosperous. The map visualization of the 50years of research accumulation showed the comparable opposition of quantitative vs. qualitative research methodologies, equation modeling,and instrument development. Conclusion These clusters of research demonstrates the efforts to make nursing evidence by Koreannursing scholars for the last five decades. The growth in the slope of KSNS and outcomes of JKAN are to carry on to an unimaginable extentin the future.

In the present study, a perfluorochemical emulsion (Fluosol-DA 20%) did not alter Do and and Dq values on cell survival curve, indicating that the lack of a direct effect of Fluosol-DA 20% on cellular radiosensitivity in vitro. The effect of Fluosol-DA 20% injection in combination with carbogen breathing was determined on the hupoxic cell fraction in SCK tumors. The hypoxic cell fraction in control SCK tumors was 0.39. This value decreased to 0.05 when the mice were i.v. injected with 12 ml/kg of Fluosol-DA 20% in a carbogen atomosphere. The measured mean and median PO2 values with a microelectorde in the control tumors was 9 mmHg and 4 mmHg, respectively. The treatment of the SCK tumors in the host mice with injected Fluosol-DA 20% in combination with carbogen breathing increased the mean and median PO2 values to 67 mmHg and 62 mmHg, respectively. Using carbogen breathing alone caused a moderate increase of tumor PO2. But Fluosol-DA 20% injection alone caused little change PO2 in the tumor. It was concluded that the combination of Fluosol-DA injection and carbogen breathing is an effective means to improve oxygenation of tumors.

BACKGROUND: Diagnosis of tuberculosis is more complicated because of low sensitivity and time consuming procedures of the conventional diagnostic methods as well as nonspecific clinical features. Recently the serologic diagnosis of tuberculosis has been reported as one of rapid sensitive and specific methods. We evaluated the ability of a rapid ICT Tuberculosis assay(AMRAD/ICT Diagnostics, Syndey, Australia) to detect pulmonary tuberculosis. METHODS: ICT Tuberculosis assay was performed to the sera from 50 patients with pulmonary tuberculosis (24 patients with smear positive, 26 patients with smear negative) and 105 controls (48 patients without tuberculosis, 57 healthy controls). RESULTS: Antibodies were detected in 22 of 24 (92%) smear positive patients and 22 of 26 (85%) smear negative patients who had been clinically diagnosed as having active pulmonary tuberculosis. Two (4.2%) out of 48 patients without tuberculosis and 1 (1.8%) out of 57 healthy controls had a positive antibody response. The overall sensitivity, specificity, and positive and negative predictive value of the ICT Tuberculosis assay were 88%, 97%, 94%, and 94%, respectively. CONCLUSIONS: The ICT Tuberculosis assay was not only sensitive and specific but also rapid and simple. This assay will be useful as a diagnostic method of pulmonary tuberculosis in combination with sputum smear and X-ray.

To study the tumor-suppression effect of a newly developed anti-tumor agent AG60 [ acriflavine (1) : guanosine (1) composition, Taerim Pharm. Co., Seoul, Korea], each Ehrlich carcinoma (107 cells)-inoculated mouse received the subcutaneous injection of 0.2 ml of saline, 5mg/kg of AG60, and 30 mg/kg of AG60, every other day for two weeks. Animals were sacrificed, and stomach, duodenum, appendix vermiformis and rectal tissues were resected and fixed in 10% neutral formalin. Tissue blocks were washed, dehydrated, embedded and cut in 6 microgram-thick sections. For immunocytochemistry, the streptavidine-biotin-peroxidse method was used with a InnoGenex (San Ramon, Calif., USA) staining kit. The tissues were incubated with rabbit antisera against somatostatin (Biogenesis, Poole, England, UK) diluted 1 : 300, secretin (Biogenesis, Poole, England, UK) diluted 1 : 2,400, neurotensin (Biogenesis, Poole, England, UK) diluted 1 : 2,600, or motilin (Biogenesis, Poole, England, UK) diluted 1 : 1,000 for 24 hour at 4dreeges C, followed by incubation in biotinylated antirabbit IgG and horseradish peroxidase-streptavidin conjugate for 1 hour at room temperature. The antigen-antibody reaction sites were visualized by incubating the sections with diaminobezidine tetrahydrochloride (DAB) for 5~15 minutes at room temperature. After mounting in canada balsam, they were examined in a Leica DM RB microscope. The number of the immunoreactive cells in the area of gastrointestinal mucosae (mean number of immunoreactive cells per 0.25mm2) were observed and calculated. The results are as follows : 1. In the fundic gland of normal mouse, somatostatin immunoreactive cells were detected (18.5+/-0.71), but neurotensin, secretin, or motilin immunoreactive cells were not found. In the duodenal mucosa of normal mouse, somatostatin immunoreactive cells were detected (7.0+/-0.10), but neurotensin, secretin or motilin immunoreactive cells were rarely found. 2. Immunoreactivity of somatostatin, secretin, neurotensin or motilin cells was not found in appendix vermiformis and rectum of normal mouse. 3. On immunocytochemical study, somatostatin immunoreactive cells in the fundic glands of normal, experimental control, AG60 (5mg/kg)-treated, AG60 (30 mg/kg)-treated and 5-fluorouracil (60 mg/kg)-treated groups were 18.5+/-0.71, 10.0+/-4.20, 11.5+/-0.71, 13.5+/-2.10, 11.5+/-2.71, respectively. 4. On immunocytochemical study, somatostatin immunoreactive cells in the duodenal mucosae of normal, experimental control, AG60 (5 mg/kg)-treated, AG60 (30 mg/kg)-treated and 5-fluorouracil (60 mg/kg)-treated groups were 7.0+/-2.10, 0.5+/-2.71, 3.0+/-1.41, 0.5+/-0.71, 2.50+/-0.71, respectively. 5. On immunocytochemical study, secretin immunoreactive cells in the duodenal mucosae of normal, experimental control, AG60 (5 mg/kg)-treated, AG60 (30 mg/kg)-treated and 5-fluorouracil (60 mg/kg)-treated groups were rarely found. 6. On immunocytochemical study, neurotensin and motilin immunoreactive cells in the duodenal mucosae of normal groups were detected, but immunoreactivies were not detected in experimental control, AG60 (5 mg/kg)-treated, AG60 (30 mg/kg)-treated or 5-fluorouracil (60 mg/kg)-treated groups.

Purpose: The purpose of this study was to analyze articles published in the Journal of the Korean Academy of Nursing (JKAN) between 2010 and 2019, along with those published in three international nursing journals, to improve JKAN’s international reputation. Methods: The overall characteristics of JKAN’s published papers and keywords, study participants, types of nursing interventions and dependent variables, citations, and cited journals were analyzed. Additionally, the keywords and study designs, publication-related characteristics, journal impact factors (JIF), and Eigenfactor scores of International Journal of Nursing Studies (IJNS), International Nursing Review (INR), Nursing & Health Sciences (NHS), and JKAN were analyzed and compared. Results: Among the four journals, JKAN’s score was the lowest in both the journal impact factor and Eigenfactor score. In particular, while the JIF of INR and NHS has been continuously increasing; JKAN’s JIF has remained static for almost 10 years. The journals which had cited JKAN and those which JKAN had cited were mainly published in Korean. Conclusion JKAN still has a low IF and a low ranking among Social Citation Index (E) journals during the past 10 years, as compared to that of four international journals. To enhance JKAN’s status as an international journal, it is necessary to consider publishing it in English and to continuously improve the conditions of other publications.
