PURPOSE: This study was designed to assess the level of super-leadership and self-leadership, identify correlations among variables and identify the factors influencing organizational commitment of clinical nurses. METHODS: Participants were 217 nurses working in four hospitals located in Seoul and Gyeonggi Province. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Scheffé test, Pearson Correlation, and Multiple Regression. RESULTS: The most influential factor for organizational commitment was super-leadership (β=.28, p<.001), followed by education (β=.16, p=.007), the number of unit nurses (β=-.18, p=.003), self-leadership (β=.17, p=.008), and the number of patients being under 10 (β=.12, p=.046). These factors accounted for 23% of the variance in organizational commitment (F=13.46, p<.001). CONCLUSION: The results of this study suggest a need for strategies to improve organizational commitment of nurses by enhancing nurse' self-leadership through nursing managers' super-leadership.

BACKGROUND: The changes of the composition in the T-lymphocyte are important as an immunological abnormality in the pathogenesis of tuberculosis. Previously, the second type of TCR dimer(gamma delta T lymphocyte) that did not express CD4 or CD8 molecules was found. In other reports the presence of this type of lymphocytes was increased in the initial stage of tuberculous infections. METHOD: To determine whether there are some differences in the T-lymphocyte subsets in the peripheral blood or pleural effusion among the forty-nine patients were examined T-lymphocyte subset analysis(CD4+T-cell,CD8+ T-cell,gamma delta T-lymphocytes) with anti-Leu4, anti-Leu3a, anti-Leu2a, anti HLA-DR and anti-TCR-gammadelta-1(Becton & Dickinson Co.). RESULTS: The average age of the patients was 50 years old(17-81year). There were 33 males and 16 female patients. patiensts with tuberculosis are 30cases(tuberculous pleurisy 15), lung cancer 12cases(malignant effusion 9) and pneumonia 7cases(parapneumonic effusion 6cases) In T lymphocyte subsets of pleural effusion, helper T lymphocyte(54.6 + 13.8 %) of tuberculous pleurisy was higher than that(36.2 + 25.3 %) of non-tuberculous pleurisy(p= 0.04). The peripheral blood gammadelta T-lymphocytes in tuberculousis was insignificantly higher than non-tuberculous patients(p= 0.24). The peripheral blood gammadelta T-lymphocytes and pleural gammadelta T-lymphocytes in tuberculous pleurisy was insignificantly higher than in non-tuberculous pleurisy(p= 0.16, p= 0.12). CONCLUSION: The percentage of gammadelta T lymphocytes among the total T-lymphocytes is not significantly increased in the peripheral blood or pleural effusion of the pleural tuberculosis. gammadelta T lymphocytes is less useful as a diagnostic method of pleural tuberculosis.

The tumorous type of endobronchial tuberculosis was reported to be 5 to 10% in the bronchoscopic examination. It was protruding mass that tuberculous mediastinal lymph node ruptured into the bronchial lumen. Generally histologic examination has been performed for purpose of differentiation, because the tumorous type of endobronchial tuberculosis simulate lung cancer in bronchoscopic finding. A case considering operation similar to bronchial adenoma in the bronchoscopic finding was confirmed to endobronchial tuberculosis by positive AFB and disapperance of mass after antituberculosis medication. Case history was presented and reviewed.

BACKGROUND: The CD4+ T-helper cells comprise functionally distinct subsets of Th1 and Th2 cells that are distinguished on the basis of differential cytokines production. Th1 cells secrete interferon-gamma, lymphotoxin, interleukin-2. Th2 cells produce interleukin-4, interleukin-5, interleukin-10. A previous study shown that Th2 cells and their cytokines increased in patients with atopic asthma. We compared cytokines(IL-4, IFN-gamma) activity and subpopulation of T-lymphocytes in peripheral blood from atopic asthmatics versus non-asthmatics. METHOD: Fifteen patients with atopic asthma(nine men, six women), twelve patients with chronic bronchitis (six men, six women), five healthy persons(three men, two women) were studied. Activity of IL-4, IFN-gamma and T-cell subpopulation in peripheral blood were estimated. RESULTS: Patients had a median age of 55yr. The mean activity of IL-4 of asthmatics was significantly increased(control 0.75+/-1.1pmol/L, atopic asthmatics 3.50+/-0.75pmol/L, chronic bronchitis 2.01+/-1.2pmol/L), but IFN- was not significantly increased. In the T lymphocyte subsets the percent of CD62L+ T-lymphocytes of asthmatics was not significantly increased(control 16.7+/-16.4 %, atopic asthmatics 24.8+/-23.6 %, chronic bronchitis 17.0+/-16.9%). CONCLUSION: In this study elevated production of IL-4 was observed in atopic asthmatics. CD62L+ T-lymphocytes was not increased in atopic asthma.

PURPOSE: To investigate the clinical characteristics and management of lacrimal gland ductal disease, a rare disease often mistaken for other diseases. METHODS: A retrospective chart review of 11 patients (11 eyes, 5 males, 6 females) diagnosed with lacrimal ductal disease between March 2007 and April 2013 was performed. RESULTS: Among 11 eyes in 11 patients, 4 were diagnosed with dacryops and 7 with lacrimal gland ductulitis initiated by dacryolith. The mean age of the subjects was 47.9 years (range, 30-80 years). Lacrimal gland ductulitis patients received treatment for conjunctivitis or hordeolum for several months. Four cases involved the right eye and 7 cases involved the left eye. Symptoms included foreign body sensation, pus-like discharge and palpable mass. Biopsy was performed in 3 cases and showed no specific findings. Patients with dacryops underwent marsupialization, whereas patients diagnosed with lacrimal gland ductulitis underwent excision and dacryolith curettage. During the 2-month follow-up period, all cases showed no signs of recurrence or complications. CONCLUSIONS: Lacrimal gland ductal disease can be mistaken for other diseases such as conjunctivitis, hordeolum, or orbital cyst, thus requiring accurate diagnosis and appropriate management.

PURPOSE: To report a rare case of a painless mass on the lower lid, histologically diagnosed as primary signet ring cell carcinoma of the eyelid. CASE SUMMARY: A 74-year-old male presented with a painless mass on the right lower lid which had developed seven months prior to presentation. Incisional biopsy of the mass and attached lower lid skin was performed, revealing signet ring cell carcinoma. A systemic evaluation, including whole body positron emission tomography-computed tomography (PET-CT), chest CT, abdomen and pelvis CT, gastrointestinal endoscopy, and colonoscopy, revealed no other abnormal lesions. Therefore, the eyelid lesion was considered primary signet ring cell carcinoma of the skin and was treated with radiotherapy of 6600 cGy in 33 fractions over 7 weeks. CONCLUSIONS: Herein, the authors report a rare case of primary signet ring cell carcinoma of the eyelid with no evidence of tumor recurrence or metastasis for 5 years after radiotherapy.

PURPOSE: The purpose of this study was to estimate the effects of a video low intensity exercise program provided during hemodialysis on fatigue, activity of daily living, positive psychological capital and blood pressure of patients being treated. METHODS: A non-equivalent control group pre-post test design was used. Participants were 85 hemodialysis patients assigned to either the experimental group (n=41) or the control group (n=44). The experimental group exercised for about 25 minutes 3 times a week for 8 weeks. Data analyses involved descriptive statistics, χ2 test, t-test, multiple regression and repeated measure ANOVA using SPSS/WIN 23.0. RESULTS: The exercise intervention significantly reduced post hemodialysis fatigue and significantly increased positive psychological capital. There was a significant interaction effect on time by group in blood pressure. Systolic blood pressure changes in the experimental group were stable but, changes in the control group tended to increase gradually. CONCLUSION: To reduce fatigue and increase positive psychological capital for hemodialysis patients, providing exercise during hemodialysis is recommended. Furthermore individualized exercise in terms of intensity, time, duration, etc should be developed and tested. Also, to reduce drastic blood pressure changes during hemodialysis, exercise should be provided.

OBJECTIVE: To investigate serum 25-hydroxyl vitamin D (25(OH)D) and vitamin D-binding protein (VDBP) concentrations in women with endometriosis according to the severity of disease. METHODS: Women with mild endometriosis (n = 9) and advanced endometriosis (n = 7), as well as healthy controls (n = 16), were enrolled in this observational study. Serum total 25(OH)D concentrations were analyzed using the Elecsys vitamin D total kit with the Cobas e602 module. Concentrations of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using the Human Vitamin D BP Quantikine ELISA kit. Variables were tested for normality and homoscedasticity using the Shapiro-Wilk test and Leven F test, respectively. Correlation analysis was used to identify the variables related to total 25(OH)D and VDBP levels. To assess the effects of total 25(OH)D and VDBP levels in the three groups, multivariate generalized additive modeling (GAM) was performed. RESULTS: Gravidity and parity were significantly different across the three groups. Erythrocyte sedimentation rate (ESR) and CA-125 levels increased as a function of endometriosis severity, respectively (p= 0.051, p= 0.004). The correlation analysis showed that total 25(OH)D levels were positively correlated with gravidity (r = 0.59, p< 0.001) and parity (r = 0.51, p< 0.003). Multivariate GAM showed no significant relationship of total 25(OH)D levels with EMT severity after adjusting for gravidity and ESR. However, the coefficient of total 25(OH)D levels with gravidity was significant (1.87; 95% confidence interval, 0.12–3.63; p= 0.040). CONCLUSION: These results indicate that vitamin D and VDBP levels were not associated with the severity of endometriosis.
