PURPOSE: The purpose of this study was to explore the relationships among workplace bullying, organizational commitment, and turnover intention of nurses. METHODS: A cross-sectional study was conducted. Data were collected using a structured questionnaire from nurses at five public hospitals (N=190). RESULTS: The experience of bullying was 31.29 points (range 16–64) on average: Work-related bullying was the highest, followed by verbal/non verbal bullying and external threats. The consequences of bullying were 30.54 points (range 13–52) on average: The physical/psychological withdrawal was the highest, followed by increasing distrust and the poor quality of patient care. The experiences of bullying had positive correlations with the consequences of bullying (r=.55, p < .001) and the turnover intention (r=.27, p < .001), and had a negative correlation with organizational commitment (r=−.28, p < .001). The consequences of bullying had a positive correlation with the turnover intention (r=.52, p < .001), and had a negative correlation with organizational commitment (r=−.49, p < .001). Organizational commitment showed a negative correlation with the turnover intention (r=.63, p < .001). CONCLUSION: The findings of this study suggests the needs of a regular monitoring system and organizational management for workplace bullying, which helps nurses to commit to their organization and to be retained in a workplace.

The L-gulono-gamma-lactone oxidase gene (Gulo) encodes an essential enzyme in the synthesis of ascorbic acid from glucose. On the basis of previous findings of bone abnormalities in Gulo-/- mice under conditions of ascorbic acid insufficiency, we investigated the effect of ascorbic acid insufficiency on factors related to bone metabolism in Gulo-/- mice. Four groups of mice were raised for 4 weeks under differing conditions of ascorbic acid insufficiency, namely, wild type; ascorbic acid-sufficient Gulo-/- mice, 3-week ascorbic acid-insufficient Gulo-/- mice, and 4-week ascorbic acid-insufficient Gulo-/- mice. Four weeks of ascorbic acid insufficiency resulted in significant weight loss in Gulo-/- mice. Interestingly, average plasma osteocalcin levels were significantly decreased in Gulo-/- mice after 3 weeks of ascorbic acid insufficiency. In addition, the tibia weight in ascorbic acid-sufficient Gulo-/- mice was significantly higher than that in the other three groups. Moreover, significant decreases in trabecular bone volume near to the growth plate, as well as in trabecular bone attachment to the growth plate, were evident in 3- or 4-week ascorbic acid-insufficient Gulo-/-. In summary, ascorbic acid insufficiency in Gulo-/- mice results in severe defects in normal bone formation, which are closely related to a decrease in plasma osteocalcin levels.

The incidence of overall cancer has increased over time. The incidence of top-ranking cancers has changed in the 1990s and the 2000s. However, few studies have evaluated the trends in metastatic skin cancers during this period. We evaluated the recent trends in incidence, peak age and location of metastatic skin cancers from 1991 to 2010. This 20-yr survey was divided into two decades to determine the trends by comparing the statistics. Out of 694,466 outpatients (1991-2010), 174 (0.025%) were diagnosed with metastatic skin cancer. The incidence of metastatic skin cancer increased significantly from 20.64 per 100,000 outpatients in the 1990s to 28.70 per 100,000 outpatients in the 2000s (P = 0.030). The peak age of skin metastasis shifted from the 40s to the 50s in women, and from the 50s to the 60s in men. The percentage of metastatic skin cancers originating from intra-abdominal organs increased from 10% in the 1990s to 23.1% in the 2000s (P = 0.027). The percentage of metastatic skin cancers located on the abdomen increased from 7.1% in the 1990s to 15.4% in the 2000s (P = 0.011). The higher proportion of metastatic skin cancers located on the abdomen may be related to the increase in skin metastases from intra-abdominal organs.

Leukemia cutis (LC) is defined as a neoplastic leukocytic infiltration of the skin. Few clinical studies are available on recent trends of LC in Korea. The purpose of this study was to analyze the clinical features and prognosis of LC in Korea and to compare findings with previous studies. We performed a retrospective study of 75 patients with LC and evaluated the patients' age and sex, clinical features and skin lesion distribution according to the type of leukemia, interval between the diagnosis of leukemia and the development of LC, and prognosis. The male to female ratio was 2:1, and the mean age at diagnosis was 37.6 yr. The most common cutaneous lesions were nodules. The most commonly affected site was the extremities in acute myelocytic leukemia and chronic myelocytic leukemia except for acute lymphocytic leukemia. Compared with previous studies, there was an increasing tendency in the proportion of males and nodular lesions, and LC most often occurred in the extremities. The prognosis of LC was still poor within 1 yr, which was similar to the results of previous studies. These results suggest that there is a difference in the clinical characteristics and predilection sites according to type of leukemia.

Mycobacterium fortuitum is one of the rapidly-growing atypical mycobacteria, belonging to Runyon group IV. M. fortuitum infection is usually related to trauma, injections and surgical procedures, and is resistant to treatment with anti-tuberculous agents. Herein, we report on a case of M. fortuitum infection after footbath. A 51-year-old male presented with painful, erythematous nodules and plaques with crust and purulent discharge on the lower legs for 3 months. The skin lesion occurred after two herb and aroma footbaths and leg massage. He went to the massage shop again, and received the footbath one more time. The skin lesion aggravated and he visited a hospital, then the skin biopsy was performed but the result was unremarkable. He was treated with antihistamine and antibiotics but there was no improvement. So he visited our hospital, and culture demonstrated atypical mycobacterium, which was identified as M. fortuitum by polymerase chain reaction. He was treated with oral clarythromycin for 5 months, and the skin lesions have improved.

We evaluated the recent trend in the incidence of premalignant and malignant skin lesions between 1991 and 2006. Among 571,057 newly registered dermatology out-patients from our 8 affiliated university hospitals, 2,598 were diagnosed with a premalignant (899, 0.16%) or malignant skin lesions (1,699, 0.30%). Of 899 premalignant cases, 71.2% were actinic keratosis (AK), and 24.6% were Bowen's disease. Of 1,699 malignant cases, 46.2% were basal cell carcinoma, followed by squamous cell carcinoma (19.1%) and melanoma (7.1%). This 16-yr survey was divided equally into two time periods to compare the incidence of premalignant and malignant skin lesions at different time settings. Between 1991 and 1998, the incidence of cutaneous premalignancy was 0.10% which doubled during 1999-2006. For cutaneous malignancy, the incidence was 0.25% during 1991-1998 and 0.34% in 1999-2006. Incidence of AK among the new outpatients was 0.07% in 1991-1998 which staggered up to 0.15% in 1999-2006. These findings show an increase of both premalignant and malignant skin lesions, AK in particular in the dermatology outpatient-based incidence.

The point prevalence of atopic dermatitis (AD) among Korean adults visiting the Health Service Center for health check-ups was assessed. AD was diagnosed based on the questionnaires filled by patients and through physical examination by dermatologists. A total of 3,563 persons completed the questionnaires, and 2,032 persons were examined by the dermatologists. According to the questionnaires, the prevalence of AD was 7.1%, and from the dermatologists' examination, it was 2.6% overall, which decreased with age significantly. The prevalence in men was higher than that of women. Grading the severity of AD according to their eczema area and severity index scores, 70.6% were classified as being mild, 25.5% moderate, and 3.9% severe. Interestingly, concomitance of psoriasis and AD was found in 0.5% of those examined by the dermatologists. Our results suggest that AD is one of the most common skin diseases not only in children but also in adults in Korea.

BACKGROUND: Chronic idiopathic urticaria (CIU) is a relatively common disease, and yet not much is known about the causative factors or its pathophysiology, which makes it difficult to cure. Due to its chronic nature, many patients have significantly reduced quality of life (QOL). OBJECTIVE: The purpose of this study was to assess the impact of CIU on QOL of Korean patients, and to determine whether a relationship exists between QOL and the severity of disease. METHODS: One hundred sixty three patients with CIU, who first visited our out-patient clinic between August 2005 and July 2007, were asked to complete two questionnaires: one designed to assess the clinical features of their disease; the other on the influences of CIU on their daily lives. QOL was divided into six categories: mental status (MS), daily living activities (DLA), leisure activities (LA), self-perception (SP), treatment-induced restrictions (TIR), and social functions (SF). All of the QOL scores were recalibrated to a 0~100 scale, with 100 indicating the worst QOL, and 0 the best. RESULTS: The average QOL scores obtained from the questionnaire were as follows: SP (13.1+/-4.6), DLA (12.0+/-4.3), MS (10.3+/-3.3), SF (8.5+/-3.4), LA (6.1+/-3.0), and TIR (5.5+/-2.6). SP was the domain that was most affected; TIR the least. There were positive correlations between pairs of the six different QOL categories (p<0.001). These results demonstrate that CIU exerts an influence on many aspects of QOL. TIR was significantly affected in longer term CIU cases (p<0.05), while SP, MS, DLA, SF, and SR scores did not correlate with disease duration. Disease severity was found to have a significant impact on SP, MS, SF, and LA (p<0.05). In patients with concurrent physical urticaria, DLA and SF scores were significantly affected (p<0.05). CONCLUSION: Based on these results, it is suggested that CIU has a negative impact on QOL in Korean patients. Therefore, it is important to recognize the effects CIU can have on QOL and consider them in evaluating the response to treatment.

Sarcoidosis is an idiopathic multisystemic disorder with variable cutaneous presentations that are classified as specific or non-specific according to the presence of non-caseating granulomas on histologic examination. Specific manifestations can include papules, scar sarcoidosis, ulcers, or even alopecia. Herein, we present a case of cutaneous sarcoidosis that presented as multiple erythematous macules and patches on the trunk and extremities of a 32-year-old man. The clinical appearance was unlike any other form reported in the literature.
