A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.

Incidence of human herpesvirus-6 (HHV-6) infection in the neonatal period has been reported in few cases. HHV-6, commonly responsible for roseola, is known to establish infection during infancy and early childhood. A 14-day-old neonate, presented with a fever of 38.3℃, primarily due to an HHV-6 infection, was admitted to our neonatal intensive care unit. A polymerase chain reaction (PCR) of his cerebrospinal fluid was positive for HHV-6. Additionally, serology for HHV-6 PCR was positive. We believe that HHV-6 can cause infection in febrile newborn infants.

PURPOSE: Focusing manner is very powerful mind-body self-help and self-awareness competence. So focusing manner may affect nurses' emotional labor and nursing performance, but few are known about it to date. The purpose of this study was to identify the degree of focusing manner, emotional labor, nursing performance of clinical nurses, and the factors that affect nursing performance. METHODS: In order to collect data, structured questionnaires were administered to 212 nurses who worked at 2 university hospitals located in D city. Data were analyzed by t-test, ANOVA, correlation and multiple regression using SPSS/WIN 20.0. RESULTS: Nursing performance had positive relationship with focusing manner (r=.45, p<.001), and negative relationship with emotional labor (r=−.25, p<.001). And the most prediction factor influencing nursing performance was focusing manner (β=.41, p<.001) and the other factors were age (β=.30, p=.002), and emotional labor (β=.14, p=.012). The total variance was 37.1% by those predictors (F=25.87, p<.001). CONCLUSION: Based on the results of this study, it is necessary to develop and educational program on focusing manner-oriented psychotherapy in order to improve the nursing performance. Also, the management system for controlling emotional labor needs to be set up for nurses in clinical settings.

In Korea, Plasmodium vivax (P. vivax) is the most common agent of malaria infection. However, as travel to regions where malaria is endemic increases, so do the numbers of Plasmodium falciparum and mixed infections. P. falciparum predominates, while P. vivax is rare in west-central Africa. We report on a case of mixed malaria infection with severe hemolytic anemia caused by P. falciparum and P. vivax in a 38-year-old man after traveling to Angola. A diagnosis of P. falciparum malaria was made by microscopic examination. However, both P. vivax and P. falciparum were detected by the polymerase chain reaction (PCR). As a radical cure P. vivax, the patient was treated with mefloquine, artemether, and primaquine. Both P. falciparum and P. vivax had disappeared from peripheral blood by admission day 4, however, low grade fever and headache persisted, and his hemoglobin and hematocrit levels were depleted. A peripheral blood smear was negative for both P. vivax and P. falciparum; however, a direct anti-globulin test and anti-nuclear antibody test were positive, suggesting immune hemolytic anemia. After conservative treatment, which included a transfusion with packed red blood cells (RBC), his symptoms and signs showed improvement and laboratory findings were normalized.

PURPOSE: To elucidate high-resolution CT(HRCT) findings and their pathologic basis in pulmonary oil embolism induced by LipiodoI-Adriamycin emulsion. MATERIALS AND METHODS: Pulmonary oil embolism was induced by infusing LipiodoI-Adriamycin emulsion through a peripheral vein in twelve Yorkshire pigs. Serial HRCT scans were performed on 2rid, 4th, 7th, 14th, and 28th day after the procedure. The pigs were sacrificed immediately after HRCT and histologic specimens were prepared in the same plane and level with HRCT. RESULTS: The basic pathology was reversible hemorrhagic edema of the lung. On HRCT, intraalveolar hemorrhage and edema in the acute stage manifested as ground-glass opacity or air-space consolidation of the whole secondary Iobule. The lesions were predominantly distributed over the dependent posterior lung fields because the specific gravity of Lipiodol is 1.28. Interlobular septal thickening due to edematous fluid collection was also associated. With the elapse of time, the extent and severity of the acute lesions resolved and, sometimes, changed into small nodular opacities. Pulmonary opacity was most severe on the post-embolization 2nd day and completely resolved within 2 weeks. CONCLUSION: Pulmonary embolization of LipiodoI-Adriamycin emulsion causes reversible hemorrhagic edema of the lung and Lipiodol toxicity seems to play a major role. HRCT findings of pulmonary oil embolism are quite different from those of pneumonia and pulmonary metastasis, which suggests the possibility of clincal application.

Norovirus (NV) has caused large outbreaks of gastroenteritis in schools. Studies of NV epidemiology in schools related to NV outbreaks have been frequently reported. However, reports of that in schools without outbreaks are not found. Presently, NV molecular epidemiology surveillance was carried out in asymptomatic food handlers working at nonoutbreak elementary schools in Incheon, Korea, in March, April and December, 2009. NV prevalence was examined by real-time reverse transcription-PCR (RT-PCR) and the positive products were re-evaluated by conventional RT-PCR for sequencing. Fecal samples (n = 776) were collected from 776 food handlers in 60 schools. NV was detected in 26 of them (3.4%). Of these, 17 (65%) were positive for NV GII and 10 (38%) were positive for NV GI. Of the 26 samples, 19 were positive by conventional RT-PCR. Sequencing of these 19 strains revealed GII/4 (n = 5), GI/6 (n = 3), GI/14 (n = 2), GII/8 (n = 2), GI/2 (n = 2), GI/10 (n = 1), GII/1 (n = 1), GII/3 (n = 1), GII/7 (n = 1), and GII/16 (n = 1). In this survey, the food handler population unrelated to NV outbreaks was found to normally contain asymptomatic carriers of NV. The excretion of NV from asymptomatic food handlers should be an infection source of NV outbreaks.

Purpose: This study aims to investigate the effects of provisional restoration fabrication methods and surface polishing on surface roughness and microbial adhesion through in vitro experiments. Materials and Methods: 120 cylindrical provisional restorationresin blocks (10 × 10 × 2.5 mm) were manufactured according to four fabrication methods, and 30 specimens were assigned toeach group. Afterwards, they were divided into non-polishing group, #400 grit SiC polishing group, and #800 grit SiC polishinggroup and polished to a 10 × 10 × 2 mm specimen size (n = 10). The surface roughness Ra and Ry of the specimen was measuredusing a Surface Roughness Tester. Three specimens were extracted from each group and were coated with artificial saliva, and then Streptococcus mutans were cultured on the specimens at 37°C for 4 hours. The cultured specimens were fixed to fixativesand photographed using a scanning electron microscope. For statistical analysis, the two way of ANOVA was performed for surfaceroughness Ra and Ry, respectively, and the surface roughness was tested post-mortem with a Scheffe test. Results: The fabrication method and the degree of surface polishing of the provisional restorations had a significant effect on both surface roughness Ra and Ry, and had an interaction effect. There was no significant difference in Ra and Ry values in all polishing groups in DLP and LCD groups. Conclusion The fabrication method and surface polishing of the provisional restoration had a significant effect on surface roughness and showed different adhesion patterns for S. mutans adhesion.
