PURPOSE: The purpose of the study was to investigate the effect of work engagement (WE) on organizational citizenship behaviors (OCB) and ability to control career commitment (CC) in the relationship between work engagement and OCB. METHODS: Data were collected using structured self-report questionnaires from 205 nurses currently working at three national hospitals. Data were analyzed using descriptive statistics, ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis using the SPSS 21.0 program. RESULTS: Mean scores for each variable were: WE 3.77 (on a 7-point scale), OCB 3.41 (on a 5-point scale), and CC 3.05 (on a 5-point scale). As a result, comparison showed that all research variables were higher with age, OCB was higher with total clinical career, and CC was higher with higher education level. Total clinical career, WE and CC had a significant effect on OCB, and CC had a moderate effect on work engagement and OCB. These variables had a total explanatory power of 38% for OCB. CONCLUSION: The nurses' WE had a positive effect on OCB, and the CC showed a moderating effect on the relationship between WE and OCB. Therefore, we suggest that CC is an important factor in improving nurses' OCB.

PURPOSE: Many young children suffer from wheezing illness during infancy, and some of them experience wheezing frequently and develop bronchial asthma ultimately. It is not clear whether the level of exposure to allergens in the environment is a significant risk factor for asthma in this clinical setting. The aim of this study was to examine the effect of level of exposure to house dust mites on the development of asthma after early childhood wheezing. METHODS: Asthmatic children(n=21) and nonasthmatic children(n=19) with the past history of wheezing illness during the first three years of age were recruited. Samples of house dusts were collected from the bedclothes in their bedrooms. We measured the amount of group I allergens from Dermatophagoides spp., Der f I and Der p I in house dusts by ELISA using monoclonal antibodies. RESULTS: In asthmatic and nonasthmatic groups, the level of Der f I was higher than that of Der p I, although the difference was not statistically significant. The level of Der f I was 4.32 microgram/gm of dust(geometric mean; range of 1 SD : 0.61-30.48) in asthmatic group and 3.72 microgram/gm(0.50-27.42) in nonasthmatic group. The level of Der p I was 2.22 microgram/gm(0.33-14.96) in asthmatic group and 2.07 microgram/gm(0.31-13.77) in nonasthmatic group. The difference between the two groups was not significant for both allergens. When the total subjects were divided into atopic(n=21) and nonatopic(n=19) groups, there was significant difference in neither Der f I nor Der p I level between atopic and nonatopic groups. CONCLUSION: Although personal atopy is important in the development of asthma after early childhood wheezing, the level of exposure to allergens in the environment may not be a significant risk factor for the development of asthma in this clinical setting.

OBJECTIVE: The aim of this study was to determine whether a significant in preoperative serum p53 autoantibodies in epithelial ovarian cancer. METHODS: Serum autoantibodies against the p53 protein (p53 AAb) were analysed with a newly developed enzyme-linked immunosorbent assay (ELISA) based on highly purified and renatured p53. In a hospital -based retrospective study, preoperative sera from 17 patients with epithelial ovarian cancer and 15 patients with benign tumors of the ovaries, 15 healthy women were studies. RESULTS: The prevalence of p53 AAb in patients with epithelial ovarian cancer was 35.3% (6/17). No p53 AAb were found in patients with benign tumors and healthy women. Presence of p53 AAb positively correlated with older age, poor response of chemotherapy. But the differences in the tumor stage, grade, poor progression free survival rate were not statistically significant. CONCLUSIONS: The assessment of preoperative serum p53 AAb seems to have a limited clinical value in the epithelial ovarian cancer.

Iron deficiency anemia (IDA) is among the five greatest causes of disability globally. It can have various causes and may develop concurrently with other health issues. Recently, there have been advances in the treatment of IDA associated with various comorbidities.Current Concepts: The causes of IDA include chronic blood loss, inadequate iron absorption, and increased iron demand. Oral iron supplements are primarily recommended for the treatment of IDA. In cases where oral supplements are ineffective or cannot be used, parenteral iron supplements are administered.Discussion and Conclusion: Identifying the underlying reason for IDA is essential for determining the appropriate and effective treatment plan. In adults, it is important to be aware that gastrointestinal malignancies can be detected as a cause of IDA. Ferrous sulfate tablets are primarily recommended as oral supplements for treating IDA. Among the parenteral iron supplements available in South Korea, both iron sucrose and ferric carboxymaltose can be used relatively safely without significant side effects. Recently, ferric carboxymaltose was reported as being effective for treating iron deficiency associated with heart failure, chronic kidney disease, inflammatory bowel disease, and preoperative IDA.

Serous surface papillary carcinoma (SSPC) of ovary is a rare malignant epithelial tumor that is histologically indistinguishable from serous ovarian papillary carcinoma. SSPC is defined as an exophytic papillary tumor originating from the surface epithelium of the ovary. It has been included in the World Health Organization classification of ovarian tumors. SSPC is believed to be a distinct subtype of serous papillary carcinoma of the ovary, and the prognosis is worse than that for serous ovarian papillary carcinoma. Clinically, SSPC usually presents with rapidly progressive intraperitoneal spread at the time of diagnosis. One woman with SSPC and malignant pleural effusion was 56 years old and presented with coughing and dyspnea. The other women was 61 years old and presented with abdominal distension. Their preoperative serum CA 125 level were 982.7 IU/mL and 4387 IU/mL. We experienced two cases of SSPC. In this case report, we present histologic findings, therapeutic modalities of SSPC with a brief review of literatures.

BACKGROUND: Hysteroscopy is considered to be the gold standard not only for visualizing the cervical canal and the uterine cavity, but also for treating many different types of benign pathologies localized to those regions. The advent and evolution of endoscopic imaging and surgery during the last two decades has added new dimensions to the armamentarium of a gynecologist to combat intrauterine lesions. Office hysteroscopy is increasingly being used as a first line investigation for abnormal uterine bleeding and other diseases involving the uterine cavity. The aim of our study is to assess the diagnostic and operative efficacy of office hysteroscopy. MATERIALS AND METHODS: In our department, 140 patients underwent a hysteroscopy examination and 18 of these underwent an office based hysteroscopy examination from September 1995 to March 2005. The cases who underwent an office based hysteroscopy examination were reviewed in order to assess the clinical usefulness and significance in the management of intrauterine lesions. RESULTS: Major indication was abnormal uterine bleeding (12 cases, 66.7%). The others were a missed IUD and infertility. The hysteroscopic findings were a normal uterine cavity (6 cases, 33.3%), IUD in situ, polyp, submucosal myoma, endometrial hyperplasia and a placenta remnant. CONCLUSION: Office hysteroscopy is a safe, quick and effective method for making an intrauterine evaluation. In addition, it provides immediate results, offers the capacity of direct targeted biopsies of suspicious focal lesions, and offers the direct treatment of some intrauterine conditions.

BACKGROUND: Weaning from mechanical ventilation is difficult in the intensive care unit (ICU). Many controversial questions remain unanswered concerning the predictors of weaning failure. This study investigates patient characteristics and delayed weaning after lung transplantation. METHODS: This study retrospectively reviewed the medical records of 17 lung transplantation patients from October 2012 to December 2013. Patients able to be weaned from mechanical ventilation within 8 days after surgery were assigned to an early group (n = 9), and the rest of the patients were assigned to the delayed group (n=8). Patients' intraoperative and postoperative characteristics were collected and analyzed, and conventional weaning predictors, including rapid shallow breathing index (RSBI), were also assessed. RESULTS: The results of the early group showed a significantly shorter ICU stay in addition to a shorter hospitalization overall. Notably, the early group had a higher body mass index (BMI) than the delayed group (20.7 vs. 16.9, p = 0.004). In addition, reopening occurred more frequently in the delayed group (1/9 vs. 5/8, p = 0.05). During spontaneous breathing trials, tidal volume (TV) and arterial oxygen tension were significantly higher in the early group compared to the delayed weaning group, but differences in RSBI and respiratory rate (RR) between groups were not statistically significant. CONCLUSIONS: Low BMI might be associated with delayed ventilator weaning in lung transplantation patients. In addition, instead of the traditional weaning predictors of RSBI and RR, TV might be a better predictor for ventilator weaning after lung transplantation.

PURPOSE: To investigate the caspase-3 expression in the acinar and ductal cells of rat submandibular glands after the irradiation of various doses. MATERIALS AND METHODS: The male Sprague-Dawley rats weighing approximately 250 gm were used for this study. The experimental group was irradiated with a single absorbed dose of 2, 5, 10, and 15 Gy on the head and neck region. The rats were sacrificed on the 1st, 3rd, 7th, 14th, 21st, and 28th day after irradiation. The specimens including the submandibular gland were sectioned and observed using histopathological and immunohistochemical methods. RESULTS: The local destruction of the acinar and ductal cells and the karyopyknotic nuclei of the acinar cells were observed in the 2 Gy and 5 Gy irradiation groups later than in the 10 Gy and 15 Gy irradiation groups. And the expression of caspase-3 was prominent only in the ductal cells in the 2 Gy and 5 Gy irradiation groups. CONCLUSION: This experiment suggests that radiation-induced apoptosis in the ductal cells of rat submandibular glands was induced by a low dose radiation associated with the activation of caspase-3 and radiation-induced necrosis was induced by a high dose radiation.
