PURPOSE: This study was conducted to identify job experiences of male hospital nurses. METHODS: Data were collected from 20 male nurses working at general hospitals, through semi-structured in-depth interviews. The interviews were recorded and subsequently transcribed verbatim. Using content analysis, data were coded and categorized. RESULTS: The analyzed domains were motivations for choosing nursing, occupational experiences (3 subdomains), and attitudes toward the future. A total of 85 significant statements were selected from the data and classified into 32 categories. The nurses' motivations for choosing nursing were advantages of employment, their aptitude, scarcity value of men, professionalism and job security, good promotion, stable income, and family influence. In occupational experiences, they were assigned to special fields and dissatisfied with vertical relationship, promotion system, their salary, and gaps in military service time; they had difficulties in adapting to female-dominated groups and encountered gender role stereotype and preconception; they were satisfied with their distinguished performance, but had damaged self-esteem, and were stressed and disappointed in their work. In their attitudes toward the future, they considered their career changes, but tried to make professional and personal advancement. CONCLUSION: These findings have implications for recruiting and retaining male nurses in clinical settings.

PURPOSE: We present a case of uneventful cataract surgery in an idiopathic true exfoliation patient with areas of capsular delamination based on scanning electron microscope and transmission electron microscope results. CASE SUMMARY: A 77-year-old male presented with gradual deterioration of vision over 1 year in duration. Slit lamp examination revealed bilateral nuclear sclerotic cataracts with ring-shaped fibrous membrane floating within the anterior chamber in the right eye. In addition, the patient was diagnosed with cataract and true exfoliation of the right eye. He underwent uneventful phacoemulsification and posterior chamber intraocular lens implantation by placing capsulorrhexis outside the delaminated capsule margin. At 6 months after cataract surgery, the patient showed favorable visual outcome with uncorrected vision of 20/20 and intraocular pressure of 18 mm Hg in the right eye.

PURPOSE: This study was to determine the mediator or moderator role of social support in the relationship between stress and depression among family caregivers of older adults with dementia. METHOD: Sixty nine family caregivers were randomly selected from health care centers in P city and a face-to-face interview was conducted using questionnaires from January to May of 2002. Data were analyzed with descriptive statistics, Pearson correlation, and hierarchical multiple regression using SPSS program. RESULT: Family caregivers of older adults with higher dependency in ADLs and higher problematic behaviors, provided care to the older adults for a longer period of time, and perceived less social support reported higher depression. Social support showed mediating effects between stress and depression, while did not show moderating effects. Elderly dependency on ADLs and caregiving duration decreased perceived social support and decreased social support increased depression. CONCLUSION: To increase family and social support to the caregivers of more functionally impaired elderly, family education to increase emotional support and physical assistance to the caregivers and broader and flexible application of social support such as increasing accessibility to the elderly daycare service with lower price may prove beneficial.

PURPOSE: To predict the accuracy of preoperative refractive error measurement methods in wavefront-guided laser-assisted subepithelial keratectomy (LASEK) surgery and to formulate a nomogram for satisfactory surgical results. METHODS: The medical records of 30 patients (57 eyes) who had undergone wavefront-guided LASEK were reviewed. The ideal surgical ablation amount was defined as the sum of the real surgical ablation amount and the remaining refractive errors. Comparison between the ideal surgical ablation amount and preoperative refractive errors was made using autorefraction, manifest refraction, cycloplegic refraction, postcycloplegic refraction, wavescan, and iTrace aberrometer measurements. RESULTS: The refractive errors measured by the postcycloplegic refraction showed the closest relation with the ideal surgical amount, and the nomogram based on this refraction correlated statistically significantly with the ideal surgical ablation amount. The refractive error using the wavescan also showed more accurate refractive measurements than the autorefractor and iTrace aberrometer. CONCLUSIONS: Accurate manifest refraction immediately before surgery is the most important in determining the ablation amount. Additionally, the refractive errors measured with the wavescan, which is an aberrometer used for wavefront-guided LASEK, showed a minimal amount of errors. After reviewing the results, the nomogram based on these 2 methods can be concluded to possibly contribute to an increase in the accuracy of surgery.

PURPOSE: Chest compression is the corner stone of resuscitation. As a result, many studies insist on the importance of retention of skill performance. But there are weak points. First, a unique characteristic of skill is ignored, "the more practice, the better outcome". Second, no one knows when they have a proficiency in a skill. Learning curve-CUSUM analysis is a good tool to evaluate each trainee's performance. Hence, we designed this study to evaluate each trainee's proficiency in performing chest compression using LC-CUSUM analysis. METHODS: Four medical students were enrolled. We asked them to perform chest compression for two minutes per day without any intervention over six weeks. Data included the depth and rate of chest compression. Eventually, all trainees performed chest compression at least 30 times. We plotted the LC-CUSUM curve according to the results of attempts, successes or failures. RESULTS: According to median values of the depth and rate of chest compression through the 30th attempt, trainees had performances within the acceptable range, 40~49 mm (for depth) and 100~105 beats per minutes (for rate) of chest compression. Nonetheless, LC-CUSUM analysis indicated that two trainees no longer were proficient throughout, and even though the rest of them were once proficient, they appear to have lost that proficiency regarding depth of chest compression. LC-CUSUM analysis of rate of compression showed that all trainees had proficiency during the early phase. CONCLUSION: We propose that instructors can evaluate their trainees' proficiency easily, based on LC-CUSUM analysis.

PURPOSE: To evaluate the clinical characteristics of vitamin D deficiency and its association with iron deficiency anemia (IDA). METHODS: A total of 171 children aged less than two years underwent 25-hydroxyvitamin D3 tests between January 2007 and July 2009. The study was classified into two groups: normal and vitamin D insufficiency, by their vitamin 25-hydroxyvitamin D3 levels. RESULTS: In total, 120 children were in the normal group (mean age, body weight and heights 12.5+/-7.0, 9.3+/-0.9 kg and 76.8+/-1.1 cm), and 51 children in the vitamin D insufficiency group (9.9+/-5.4 months, 9.0+/-0.9 kg and 75.1+/-0.9 cm). Vitamin D insufficiency was most commonly diagnosed in the spring (44%). The proportion of complete breast-feeding was higher in the insufficiency (92%), and 25.5% of the children in the deficient group also experienced IDA compared that 12% of normal group. Ten children in the insufficiency group experienced bony changes. Six children received calcitriol medication in the normal group, in whom the mean vitamin 25-hydroxyvitamin D3 level increased from 39.6+/-14.6 ng/mL (pre-medication) to 41.8+/-17.2 ng/mL (post-medication), and 13 in the insufficiency group, in whom the mean vitamin 25-hydroxyvitamin D3 increased from 20.7+/-7.0 ng/mL to a mean post-treatment level of 43.7+/-23.8 ng/mL. CONCLUSION: This study demonstrated that approximately 30% of children aged < or =2 years experienced vitamin D insufficiency associated with subclinical rickets. Many children also experienced concurrent IDA. Guidelines for vitamin D supplement in such children must therefore be established.

Radiation recall dermatitis gap (RRD) is the development of an inflammatory reaction throughout a previously irradiated area, precipitated by the administration of certain drugs. Usually chemotherapeutic agents have been associated with RRD, but other drugs reported include tamoxifen, interferon alfa-2b, simvastatin, and antituberculous drugs. We present a case of RRD after chemotherapy with letrozol (Femara(R)). Letrozol is a third generation aromatase inhibitor, which acts as an anti-estrogen agent. This is the first reported case of RRD triggered by letrozol.

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. There are several clinical forms, such as blue nevus, mongolian spot, nevus of Ota, nevus of Ito and dermal melanocyte hamartoma. Differential diagnostic features of these dermal melanocytic lesions depend on onset, course, distribution and histologic feature. A 24-year-old woman presented with an asymptomatic 6x3.5cm bluish-to-grayish speckled patch on the left calf, which had been there since birth. Histopathologic findings, using Hematoxylin & eosin staining, revealed marked increase in the infiltrate of pigment cells mainly in the upper dermis. The patient was treated twice with a Q-switched Nd-YAG laser (Medlite Co., USA). Clinical improvement was observed. Herein, we report a case of dermal melanocyte hamartoma treated with a Q-switched Nd-YAG laser.

PURPOSE: Barriers to cardiopulmonary resuscitation (CPR) education are magnified by relative cost and course availability. E-learning has emerged as a viable solution for continuous, on-demand training and organizational learning. We assessed the hypothesis that E-learning is a viable strategy for CPR training of the general public and sought to evaluate its effects on CPR quality compared to traditional classroom-based methods. METHODS: The E-learning program was specifically designed to teach basic life support skills, and consisted of 50 minutes internet lectures and simulation videos. The training session was freely available to twenty two officers in rural South Korea. The trainees were able to practice with a mannequin and an automated external defibrillator (AED) trainer at their place of employment over the course of 3 days. The control group was trained at a hospital by certified instructors using the same equipment during a 2 hour period. At the end of the course, the participant's skills were evaluated using a checklist and a skill performance test. RESULTS: Forty two subjects were enrolled finally with 19 and 23 belonging to the E-learning and the control groups, respectively. One E-learning trainee was excluded because he was absent from the skills test. The mean time to learn CPR and AED techniques was 29.0+/-24.5 minutes in the elearning group. The mean age of the E-learning group was significantly older than that of the control group (32.4+/-4.0 vs. 26.0+/-1.5, p<0.001). However, we did not find any significant differences in their weight, height or CPR educational status. Before the education sessions, the willingness to perform CPR and their confidence in performing CPR were not significantly different among the two groups. Regarding skill performance, there were no significant differences between the groups except the volume of ventilation. The control group showed a higher volume of ventilation than the elearning group (1,031.7+/-521.6 vs. 548.8+/-303.3, p=0.004). CONCLUSION: E-learning accompanied with appropriate practice can be a helpful tool for public CPR training. The demand for E-learning will increase, and this study shows that e-learning programs can be successful, yielding similar results as traditional, classroom-based training.
