Tufted hair follliculitis is a localized, inflammatory and exudative disease of the scalp characterized by a tufted appearance of the scalp hairs emerging from single follicular openings, and may result in permanent and irreversible scarring alopecia. We report two cases of tufted hair folliculitis in a 53-year-old woman and a 47-year-old man. They had several areas of scarring alopecia with multiple bundles of hairs emerging from single follicular orifices. Histopathologic findings were typical for tufted hair folliculitis. The patients were treated successively with oral antibiotics and with topical application of clindamycin.

PURPOSE: The purposes of this study were to compare postmortem fetal MRI findings with autopsy findings and to assess whether postmortem MRI can replace autopsy. MATERIALS AND METHODS: The study group consisted of 13 stillborn fetuses, seven that died immediately after birth, and five terminated because of anomalies seen on prenatal sonograms. A total 17 were male, and eight were female, and their gestational ages were from 20 to 41 (average; 28.2) weeks. Spin-echo T1-and T2-weight-ed axial, sagittal, and coronal MR images were obtained, and autopsy findings were divided into major and mi-nor. A major finding was defined as an anomaly or syndrome which caused fetal death or termination of the pregnancy; minor findings were classified, on the basis of gross inspection, as internal or external. MR images were retrospectively analyzed by two radiologists unaware of the autopsy findings, and by comparison with these, the postmortem MRI detection rates for major and minor findings was then determined. RESULTS: In seven of 25 fetuses, MR imaging revealed major findings, a detection rate of 100%. There were two cases of anencephaly, two of trisomy-18, and one each of hydrops fetalis with large cystic hygroma, diaphrag-matic hernia, and Dandy-Walker malformation. Twenty-three of 60 minor findings (38.3%) were detected by MRI. The detection rates for external and internal findings were 29.6%(8/27) and 45.5%(15/33), respectively. CONCLUSION: Although a limitation of our study is the low detection rate for minor findings, postmortem fetal MRI may help diagnose the major cause of fetal death.

PURPOSE: The aim of this study was to determine the influence of various factors on preterm labor symptoms (PLS) and preterm birth (PB). METHODS: This prospective cohort study included 193 women in the second stage of pregnancy. Multiple characteristics including body mass index (BMI), smoking, and pregnancy complications were collected through a self-report questionnaire. Pregnancy stress and PLS were each measured with a related scale. Cervical length and birth outcome were evaluated from medical charts. Multiple regression was used to predict PLS and logistic regression was used to predict PB. RESULTS: Multiple regression showed smoking experience, pregnancy complications and pregnancy specific stress were predictors of PLS and accounted for 19.2% of the total variation. Logistic regression showed predictors of PB to be twins (OR=13.68, CI=3.72~50.33, p<.001), shorter cervix (<25mm) (OR=5.63, CI=1.29~24.54, p<.05), BMI >25 (kg/m²) (OR=3.50, CI=1.35~9.04, p<.01) and a previous PB (OR=4.15, CI=1.07~16.03, p<.05). CONCLUSION: The results of this study show that the multiple factors affect stage II pregnant women can result in PLS or PB. And preterm labor may predict PB. These findings highlight differences in predicting variables for pretrm labor and for PB. Future research is needed to develop a screening tool to predict the risk of preterm birth in pregnant women.

Sézary syndrome is an aggressive, leukemic cutaneous T-cell lymphoma variant, characterized by a triad of circulating neoplastic T cells and erythroderma with/without associated lymphadenopathy. A 51-year-old man presented with erythroderma and multiple nodular skin lesions over the face. The facial skin was thickened, producing “leonine facial” appearance. On physical examination, the axillary and inguinal lymph nodes were enlarged. Investigations revealed the presence of atypical lymphoid cells in the peripheral blood, bone marrow, and skin. The histopathology of skin showed dermal infiltration of atypical small lymphocytes with mild epidermotropism. Immunohistochemical studies showed that the infiltrated cells were positive for CD3 and CD4, but negative for CD8 and CD20. A diagnosis of Sézary syndrome was made based on the clinical, peripheral blood, and immunophenotypical findings.

PURPOSE: This study was done to identify the relationship of emergency department(ED) nurse's job characteristics, organizational commitment and turnover intention. METHOD: This study was conducted through a survey of 171 nurses from ED in nine general hospitals of B and U cities. The data were collected by self-report questionnaires and analyzed with the SPSS WIN 17.0 program using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. RESULTS: The mean score for job characteristics was 3.37. Job characteristics according to position, number days night duty, and monthly income showed significant differences. Turnover intention according to age, total career, and monthly income showed significant differences. A significant positive correlation was found between job characteristics and organizational commitment. Significant negative correlations were found between job characteristics and turnover intention, organizational commitment and turnover intention were found. The significant factors influencing turnover intention were organizational commitment, monthly income, and total career, which explained 27.6% of the variance. CONCLUSION: The findings indicate that nurse managers should analyze the reasons for high turnover intention, focusing on the main factors affecting turnover intention and consider solutions for decreasing turnover intention.

Adhesion events of monocytes represent an important step in inflammatory responses induced by chemokines. The β1-integrin CD29 is a major adhesion molecule regulating leukocyte migration and extravasation. Although several adhesion molecules have been known as regulators of CD29, the molecular interactions between CD29 and its regulatory adhesion molecules (such as CD98 and CD147) have not been fully elucidated. Therefore, in this study, we examined whether these molecules are functionally, biochemically, and cell-biologically associated using monocytic U937 cells treated with aggregation-stimulating and blocking antibodies, as well as enzyme inhibitors. The surface levels of CD29, CD98, and CD147 (but not CD43, CD44, and CD82) were increased. The activation of CD29, CD98, and CD147 by ligation of them with aggregation-activating antibodies triggered the induction of cell-cell adhesion, and sensitivity to various enzyme inhibitors and aggregation-blocking antibodies was similar for CD29-, CD98-, and CD147-induced U937 cell aggregation. Molecular association between these molecules and the actin cytoskeleton was confirmed by confocal microscopy and immunoprecipitation. These results strongly suggest that CD29 might be modulated by its biochemical and cellular regulators, including CD98 and CD147, via the actin cytoskeleton.

PURPOSE: The purpose of this study was to identify the factors influencing emergency department (ED) nurses' turnover intention. METHODS: The study was conducted with 241 nurses from ED of 20 general hospitals in Busan. The survey data were collected from May 1 to July 31, 2010 and were analyzed using frequencies, percentages, means, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression with the SPSS Win 17.0 program. RESULTS: There were statistically significant differences in turnover intention depending on age, regular change in department, and nursing experiences. A significant positive correlation was found between job stress and turnover intention and a significant negative correlation between organizational commitment and turnover intention. The significant factors influencing turnover intention were regular change in department, job stress, and organizational commitment, which explained about 13.7% of the variance. CONCLUSION: Considering this results, nursing managers should analyze these main factors which affect turnover intention and create ways to decrease turnover intentions, and thus decrease high turnover intention.

This study analyzed the prevalence of metabolic syndrome and influencing factors among adult workers aged 19 to 64. Methods: Data from the ninth Korea National Health and Nutrition Examination Survey conducted in 2022 were utilized. The sample comprised 685 individuals who had measurements of fasting glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, and waist circumference, which are necessary to diagnose metabolic syndrome. Data analysis was performed using SPSS 26.0, and complex sample logistic regression was conducted to identify factors influencing metabolic syndrome. Results: Among the participants, 34.3% were diagnosed with metabolic syndrome. Significant differences were observed in sex, age, region, marital status, regular worker, and physical activity between participants with and without metabolic syndrome (p < .05). Factors influencing the prevalence of metabolic syndrome included sex, age (with the 19~29 age group showing a significantly lower risk), physical activity, smoking, and perceived stress levels (p < .05). Conclusion: To prevent metabolic syndrome in adult workers, it is essential to promote physical activity, discourage smoking, and encourage effective stress management.
