BACKGROUND AND OBJECTIVES: Storage mites, Tyrophagus putrescentiae (TP) and Acarus siro (AS), known as the major causative allergens to people who deal with stored foods and grains, may occur more frequently in house dust than expected. During the recent 6 months, positive reactions to TP and AS were observed as frequently as those to Dermatophagoides pteronyssinus (DP) in patients with allergic rhinitis in Pusan. The purpose of this study was to identify allergenic components within TP and AS, and evaluate the cross reactivity with DP. MATERIALS AND METHODS: Using extracts of DP, TP and AS, prepared after dialysis and lyophilization, allergenic components were identified using SDS-PAGE and western blotting. Cross reactivity among them were evaluated by inhibition tests using pharmacia CAP system. RESULTS: The protein components of DP, TP and AS, showed different patterns in SDS-PAGE. Molecular weight of major IgE binding components of TP were 17 kD, 25 kD and 67 kD, and those of AS were 18 kD, 19 kD, 25 kD and 27 kD. TP- or AS-specific IgE was partially inhibited by DP extract; however, DP-specific IgE was not significantly inhibited either by TP or AS extract. Significant inhibition were noted between TP and AS. CONCLUSION: TP and AS may share common allergens with DP. However, sensitization to TP or AS was also suspected in some cases. The percentage of Acaridae family in Pusan was 12% of total mites. Therefore, storage mites should be considered as causative allergens and included in allergy test battery.

PURPOSE: To analyze localized RNFL defect cases that were identified in retinal nerve fiber layer (RNFL) fundus photographs but not in optical coherence tomography (OCT). METHODS: Analysis of OCT scans and images was performed for 14 eyes (17 locations) that showed localized RNFL defects in RNFL fundus photographs but not in RNFL thickness average analysis. RESULTS: With respect to the range of RNFL defects, 41.2% were less than 10degrees, 47.0% were 11 to 20degrees, and 11.8% were 21 to 30degrees. In 71.4% of the RNFL cases the defects were less than 10degrees and the decrease of RNFL thickness was not readily observable on the OCT scan images. In all cases of RNFL defects in the 11 to 30degrees range the decrease in RNFL thickness could be assessed on the OCT scan images. Nonetheless, the decrease of RNFL thickness could not be seen on the OCT analysis images in which the results of the RNFL thickness made through an automated computer algorithm were displayed. CONCLUSIONS: The range of localized RNFL defects that were difficult to detect with OCT consisted of those cases that were almost less than 20degrees. The limitations of the OCT scan itself in patients with RNFL with an angular width defect less than 10degrees and the problems of RNFL thickness analysis processing in patients with an angular width of 11 to 30degrees may decrease the sensitivity of OCT in diagnosing RNFL defects.

PURPOSE: The results of anal fistula treatments have improved with the development of the anal fistula operative technique. However, there are still complications, such as recurrence and anal incontinence. To this end, the authors classified anal fistulas by using Sumikoshi's classification and performed an anal-sphincter-preserving procedure. METHODS: We experienced 98 anal fistula cases involving 86 patients who underwent anal fistula operations at The Catholic University of Korea, St. Vincent's Hospital from January 2001 to December 2006. This study was done retrospectively by chart review and telephone questioning. The follow-up period was from 2 to 72 months (mean 29.5, SD: 19.1). RESULTS: The study showed 0 cases of Type I (0.0%), 49 cases of Type II (50.0%), 46 cases of Type III (46.9%), and 3 cases of Type IV (3.1%) fistulas. Among the 98 fistula-in-ano operations were 27 (27.6%) of fistulotomies and 71 (72.4%) sphincter-preserving procedures (2 cases of coring-out+muscle filling+rectal mucosal advancement flap, 31 cases of coring-out+ muscle closure+rectal mucosal advancement flap, 28 cases of coring-out+cutting seton, and 10 cases of loose seton). After the sphincter-preserving operation, there were 4 cases (4/71, 5.6%) of recurrence. There were no major disorders of the anal sphincter. However, minor disorders of the anal sphincter (6/71, 8.5%, soiling) were found. CONCLUSIONS: The anal-sphincter-preserving procedure is very effective in preventing recurrence and anal incontinence, but these results are from a retrospective study with a small number of patients and the follow-up period was short. If further cases are collected and continuous follow-up is done, better results can be expected.

PURPOSE: The purpose of this study was to identify the relationship between hope, depression and suicidal ideation in patient with chronic mental illness patients. METHODS: The subjects were 188 patient with chronic mental illness in a Community Mental Health Center. The data were collected from July 27 2009 to August 21, 2009. Data were analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. RESULTS: There was found significant and negative correlation among hope and suicidal ideation; significant and positive correlation was found between depression and suicidal ideation; a significant and negative correlation among hope, depression and suicidal ideation. Depression was a significant predictor of suicidal ideation. CONCLUSION: Hope, depression and suicidal ideation in chronic mental illness patients, and significant correlations between their relationships. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes increasing the hope and decreasing depress in order to decrease suicidal ideation.

We report a case of irreducible atlantaxial dislocation with spinal cord injury. The patient was a 36-year-old man who suffered from the sudden onset of shallow respiration and severe motor weakness after slip down. We have performed the one-stage operation, the transoral decompression, reduction and posterior interspinous wiring with bone fusion. Three weeks after surgery, the reduction state and posterior wiring procedure were failed, due to severe osteoporotic change. So, we have performed second operation, the transarticular facet screw fixation and occipito-cervical fixation with Steinmann pin, from which good postoperative stability and neurological improvements, were obtained.

In this article, we critically reviewed various literatures on stress and adjustment in medical schools as a preliminary work for the future empirical study. We adopted Biopsychosocial Model as the frame of reference, which considers not only the relationship between stressor and psychological distress, but also their interaction with moderating variables such as psychosocial resources and vulnerabilities. According to the model, three important aspects of medical school stress were reviewed: 1) the types of medical school stresses, 2) the adverse effects of stressors on the adjustment such as depression, anxiety, physical symptoms, drug abuse, eating problem, attrition, change of attitude and personality, etc, 3) the moderating effects of various vulnerabilities and resources including Type A behavior pattern, masculinity/femininity, locus of control, optimism, anger expression, coping style, social support, and study skills on the suppression or development of psychological distress. Investigating the moderating variables in particular may have great clinical implications since these variables are closely related to the psychological factors concerning successful adjustment in medical school. Conclusions drawn from this review suggests several directions of future research. First, a comprehensive study which covers the whole process of medical school stress is recommended. Longitudinal design will be more suitable for dealing with the developmental features of medical education. Finally, the severity of medical school stress must be compared with the stress of general colleges and other professional graduate schools. This article is expected to provide some theoretical basis for future studies regarding the successful adjustment in the medical school, the development of preventive intervention programs and the reform of medical education systems.

Cylindrocarpon destructans is an ascomycete soil-borne pathogen that causes ginseng root rot. To identify effective biocontrol agents, we isolated several bacteria from ginseng cultivation soil and evaluated their antifungal activity. Among the isolated bacteria, one isolate (named JH7) was selected for its high antibiotic activity and was further examined for antagonism against fungal pathogens. Strain JH7 was identified as a Chromobacterium sp. using phylogenetic analysis based on 16S rRNA gene sequences. This strain was shown to produce antimicrobial molecules, including chitinases and proteases, but not cellulases. Additionally, the ability of JH7 to produce siderophore and solubilize insoluble phosphate supports its antagonistic and beneficial traits for plant growth. The JH7 strain suppressed the conidiation, conidial germination, and chlamydospore formation of C. destructans. Furthermore, the JH7 strain inhibited other plant pathogenic fungi. Thus, it provides a basis for developing a biocontrol agent for ginseng cultivation.
