Nontuberculous mycobacteria usually cause systemic disease and often appear as a primary pulmonary infection. However, a cutaneous lesion may be the first or only sign of infection. The most frequent human diseases caused by Mycobacterium fortuitum are cutaneous or soft tissue infections, usually preceded by injection, trauma or surgery. We report a case of a cutaneous lesion due to Mycobacterium(M.) fortuitum occuring in a 50-year-old man with a subcutaneous flat nodule on his left anterior tibia. He had received a small injury to his left shin in a swimming pool. The culture from the skin biopsy specimen on Lowenstein-Jensen medium yielded clolnies after 5 days. The microorganism was subsequently identified as M. fortuitum by selected biochemical reactions. Therapy was instituted with minocycline for 5 months.

The uptake of glucose for metabolism and growth is essential to most animal cells and is mediated by glucose-transporter (GLUT) proteins. The aim of this study was to determine which class of glucose transporter molecules was responsible for uptake of glucose in the mouse early embryo and at which stage the corresponding genes were expressed. In addition, co-culture system with vero cell was used to investigate the effect of the system on GLUT expression. Two-cell stage embryos were collected from the superovulated ICR female and divided into 3 groups. As a control, embryos were cultured in 0.4% BSA-T6 medium which includes glucose. For the experimental groups, embryos were cultured in either co-culture system with vero cells or glucose-free 76 medium supplemented with 0.4% BSA and pyruvate as an energy substrate. 2-cell to blastocyst stage embryos in those groups were respectively collected into microtubes (50 embryos/tube). Total RNA was extracted and RT-PCR was performed. The products were analysed after staining ethidium bromide by 2% agarose gel electrophoresis. Blastocysts were collected from each group at 120hr after hCG injection. They were fixed in 2.5% glutaraldehyde, stained with hoechst, and mounted for observation. In control, GLUT1 was expressed from 4-cell to blastocyst. GLUT2 and GLUT3 were expressed in morula and blastocyst. GLUT4 was expressed in all stages. When embryos were cultured in glucose-free medium, no significant difference was shown in the expression of GLUTI1, 2 and 3, compared to control. However GLUT4 was not expressed until morular stage. When embryos were co-cultured with vero cell, there was no significant difference in the expression of GLUT1, 2, 3 and 4 compared to control. To determine cell growth of embryos, the average cell number of blastocyst was counted. The cell number of co-culture (93.8+/-3.1, n=35) is significantly higher than that of control and glucose-free group (76.6 +/- 3.8, n=35 and 68.2+/-4.3, n=30). This study shows that the GLUT genes are expressed differently according to embryo stage. GLUTs were detectable throughout mouse preimplantation development in control and co-culture groups. However, GLUT4 was not detected from 2- to 8-cell stage but detected from morula stage in glucose-free medium, suggested that GLUT genes are expressed autocrinally in the embryo regardless of the presence of glucose as an energy substrate. In addition, co-culture system can increase the cell count of blastocyst but not improve the expression of GLUT. In conclusion, expression of GLUT is dependent on embryo stage in preimplantation embryo development.

Hailey-Hailey disease is a rare hereditary dermatosis that begins in the 2nd or 3rd decade of life. The skin lesion is characterized by a localized, recurrent eruption of small vesicles on an erythematous base. It courses remissions and exacerbations. It seldom begins in early childhood, and main treatment modalities are conservative ones. We report a case of Hailey-Hailey disease that began on a 7-month old infant and improved by surgical treatment. In according to review of the previous reports, it is probably the earliest onset age and it is may be the first case which was treated with surgery in Korea.

PURPOSE: The purpose of this study was to analyze the prevalence of allergic disease among elementary school students in rural and urban areas. METHODS: In this study, 1,513 elementary students (1,163 in urban areas, 350 in rural areas) were surveyed. Data were analyzed using frequency, percentage of allergic symptoms and chi2 test was used to identify differences in the prevalence of allergic symptoms between urban and rural area students. The SAS program was used in the data analysis. RESULTS: There were significant differences in the prevalence of allergic disease according to whether there was a family member with a prior history of allergy symptoms. 48.7% of surveyed students (49.4% in urban, 46.3% in rural) had allergic symptoms. Allergic rhinitis was the most frequent allergic symptom in both urban and rural students. CONCLUSION: These results suggest that there is a need to prevent and manage allergies among elementary students. The family history should be considered an important factor when a program for allergy prevention and management is developed. Interventions are needed in both areas, especially for students with allergic rhinitis.

PURPOSE: The purpose of this study was to analyze the effects of a health education program to improve knowledge about environmental health and allergy symptoms among elementary school students. METHODS: This study has nonequivalent control group pre-post test design. Participants of this study were 60 elementary students (30 experimental and 30 control) who agreed to participate in the study. The education program consisted of information on environmental health and allergies, the atmosphere, indoor environments, food and allergies, and activities with parents. The program was carried out one time (50 minutes) per week during 6 weeks. Knowledge and symptoms of allergies were recorded before and after the program among both groups. The collected data were analyzed by ANCOVA and t-test using SAS program. RESULTS: There was a significant increase in knowledge about allergies in the experimental group compared to the control group, but allergic symptoms were similar in the two groups. CONCLUSION: These findings suggest that environmental health education programs are effective in the area of school health nursing for increasing knowledge about environmental health and allergies. Further research is needed to develop programs for reducing allergic symptoms as an environment health problem among children.

Hantaviruses are members of the family Bunyaviridae, the etiologic agents of Hemorrhagic fever with renal syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS). They are negative-sense, single-stranded RNA viruses possessing a large (L), medium (M) and small (S) genomic segment which encodes a viral polymerase, envelope glycoproteins (G1 and G2) and a nucleocapsid (N) protein, respectively. Seoul (SEO) virus, the causative agent of clinically mild HFRS in worldwide, was isolated from lung tissues of urban rat (Rattus norvegicus) captured in Seoul, Korea, 1982. To clarify the antigenic characteristics and the differentiation of serotypes of hantavirus, 8 hybridoma cell lines secreting monoclonal antibodies (MAbs) against SEOV 80-39 strain were produced by fusion of SP2/0-Ag14 mouse myeloma cells with spleen cells of BALB/c mice, immunized with SEOV. Reactivities of these MAbs were examined by the indirect immunofluorescence assay (IFA), enzyme linked immunosorbent assay (ELISA), immunoblot, high density particle agglutination (HDPA) and plaque reduction neutralization test (PRNT). Eight out of 235 hybridomas secreted MAbs of Seoul virus 80-39 continuously, and these eight MAbs were all IgG. The isotypes of these 8 MAbs are; one clone (F3-3C) was IgG1, six (F1-1B9B, F1-3B, F1-3D, F4-1E, F4-3F, F4- 6C) were IgG2a and one (F1-1B9F) was IgG2b. Seven MAbs (F1-1B9B, F1-1B9F, F1-3B, F1- 3D, F3-3C, F4-1E, F4-3F) reacted with nucleocapsid protein (M.W. 50K) of SEOV by immunoblot. All eight MAbs were cross-reacted with Hantaan (HTN) virus, one (F4-3F) was cross-reacted with Puumala (PUU) virus and two (F1-1B9B, F1-3B) were cross-reacted with Prospect Hill (PH) virus by IFAT. None of these 8 MAbs had neutralizing activity.

PURPOSE: The aim of this study is to investigate the periodical changes of birth rate, perinatal risk factors and outcome of newborns in multi-cultural families with Korean male and non-Korean, Asian female in Gwangju, Chonnnam province. METHODS: We enrolled newborns born in or transferred from other hospital to Chonnam National University Hospital between January 2001 and December 2010. They were categorized into two periods: data from 2001 to 2005 was defined as period I and from 2006 to 2010 was defined as period II. The clinical data of the birth rate, perinatal risk factors and outcome were retrospectively reviewed. RESULTS: Number and rate of newborns in multicultural families increased significantly. The nationality of the mother changed: Vietnamese, Chinese and Cambodian significantly increased; and Japanese and Filipino significantly decreased. As the maternal age tended to be younger in period II, the age gap between the spouses increased, and the paternal age significantly increased, especially in age group of over 45 year-old. Among other perinatal risk factors, premature rupture of membranes and oligohydramnios were decreased. There were no statistical difference in morbidity (except hyperbilirubinemia) and mortality. However, congenital anomalies significantly increased. CONCLUSION: As the number of newborns in multicultural families has increased, the incidence of congenital anomalies also increased. We carefully presumed this result could be caused by increasing paternal age. Careful concern and management are needed for these families and further prospective studies are needed in a larger number of subjects.
