PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.

INTRODUCTION: The practicing of patient-centered medical services means a change in the pattern of the nature of doctor-patient relationship. The doctor oriented relationship is now moving to the pattern that patients resolve problems autonomously and participate in the decision-making in medical services. Authors performed this study to investigate the patient centeredness and influencing variables in medical students. METHODS: Authors recruited 94 medical students before psychiatric clinical clerkship and all subjects were assessed by structured questionales including socio-demographic data, frequency of receiving doctor-patient relationship lectures, Minnesota multiphasic personality inventory (MMPI), Meyers-Briggs type indicator (MBTI), the authoritarian personality scale (AP), job satisfaction scale (JS), patient practitioner orientation scale (PPOS), problem-solving decision-making scale (PSDM), and Beisecker locus of authority in decision-making scale (BLAS), and the questionnaire of JS, PPOS, PSDM, and BLAS were rechecked after psychiatric clinical clerkship. RESULTS: After psychiatric clinical clerkship, the score of JS, PPOS were higher than before. The group who had a good memory for taking a doctor-patient relationship lecture showed higher scores of the BLAS and PSDM than unexposed group. The AP was related with MBTI, correlated with the subscale of MMPI, however, inversely correlated with PPOS after psychiatric clinical clerkship. CONCLUSION: The authoritarian personality trait was related not only with other personality trait including introversion and psychopathic deviation (Pd) but also with patient-centeredness. Taking a lecture in doctor-patient relationship is positively related to the patient-centeredness.

BACKGROUND: Nalbuphine is one of the opioid agonist-antagonists and is used frequently in the anesthetic field. Usage is focused on potent analgesic action and the adjuvant of narcotics because of less complications with preserved analgesia. The most common routes of administration for postoperative pain control are epidural and intravenous, so we compared both pharmacokinetic profiles. METHODS: Twelve patients were randomly divided into two groups. All patients were given a spinal anesthesia with tetracaine hydrochloride. One group (n = 6) received nalbuphine 10 mg via epidural route and another group (n = 6) received the same dose via intravenous route. Venous blood was drawn at 0, 0.25, 0.5, 1, 2, 4, 6 and 8 hours to measure plasma nalbuphine concentrations. Analysis was performed by high performance liquid chromatography with an electrochemical detector. RESULTS: At 0.25 hour, the plasma concentration of nalbuphine was significantly higher in the epidural administration group (49.48 +/- 4.98 ng/ml) than in the intravenous administration group (40.44 +/- 1.64 ng/ml). At 6 and 8 hours, the plasma concentration of nalbuphine was significantly higher in the epidural administration group (5.98 +/- 1.86 ng/ml, 3.85 +/- 0.94 ng/ml) than in the intravenous administration group (3.80 +/- 0.33 ng/ml, 2.43 +/- 0.32 ng/ml). Clearance, elimination half life, volume of distribution and AUC were not significantly different between the two groups. CONCLUSIONS: The plasma concentrations of nalbuphine via epidural route and intravenous route were similar in both groups after 0.25 hour to 6 hours. At 0.25 hour and after 6 hours, the epidural administration group had a higher plasma concentration of nalbuphine than the intravenous administration group.

Purpose: Granular corneal dystrophy type 2 (GCD2) is a hereditary disease that features granular and lattice stromal deposits in the cornea. There are homozygotes and heterozygotes and the opacities are exacerbated by corneal trauma or surgery, such as laser in situ keratomileusis (LASIK). As there is individual variability in GCD2 phenotypes, we investigated various corneal features of GCD2 patients in their twenties, the main age group for refractive surgery. Methods: From genetically confirmed GCD2 patients who had an R124H mutation of the transforming growth factor β induced (TGFBI) gene at age 20 to 29 years, we chose representative patients: one homozygote; one compound heterozygote; one simple heterozygote with a severe phenotype with many granular deposits; one common heterozygote; and four heterozygotes with normal corneas. The corneas of all patients were subject to slit-lamp examination and photographed. Results: The homozygote had confluent granular deposits covering the cornea. The compound heterozygote had granular and lattice deposits covering the center of the cornea. The patient with a severe phenotype had more than 30 granular deposits in one eye, but was a simple GCD2 heterozygote, verified by full-sequencing of the TGFBI gene. In the four patients with normal corneas, a single small lesion was subsequently detected during follow-up in two, at 3 weeks and 6 months, respectively. Both corneas were judged clear at chance examinations. Conclusions Among Koreans in their twenties, GCD2 patients have various phenotypes, from clear corneas to severe confluent opacities. There are GCD2 heterozygotes with nearly clear corneas, so caution must be taken when choosing patients for refractive surgery.

Purpose: Contrast sensitivity, the ability to distinguish the relative difference in luminance of an object from its surrounding or adjacent objects, is a useful measure of visual function. In granular corneal dystrophy type 2 (GCD2), opacity of the corneal stroma causes deterioration in visual function. We compared the contrast sensitivity of GCD2 patients before and after phototherapeutic keratectomy (PTK) to evaluate the perioperative visual function in these patients. Methods: This study included 22 eyes of heterozygote GCD2 patients. The visual acuity and contrast sensitivity were measured before and after PTK. The contrast sensitivity was measured in mesopic and photopic background luminances, with glare (G) levels of 0-2 (G0, G1, and G2, respectively) and spatial frequencies at 1.5, 3, 6, 12, and 18 cycles per degree (cpd). Results: The contrast sensitivity increased after PTK at 1.5 and 3 cpd in mesopic and photopic conditions with G0-2 glare (p < 0.05). At 6 cpd, the contrast sensitivity increased in the mesopic condition with G1 glare, and in the photopic condition with G0-2 glare (p < 0.05). However, there was no change in contrast sensitivity at any glare level at 12 and 18 cpd after PTK. Conclusions In GCD2 patients, the contrast sensitivity increased significantly after PTK. The vision of GCD2 patients, which is decreased due to corneal opacity, is improved after PTK.

BACKGROUND: Adequate depth of anesthesia requires a sufficient amount of the agent to secure unconsciousness and other components of anesthesia as needed for that particular surgical procedure, without jeopardizing vital organ functions. To evaluate the relationship of depth of anesthesia to EEG, we studied the effects of increasing minimum alveolar concentration (MAC) of isoflurane (arousal, 1, 1.3, 1.5 MAC) on power spectral analysis of the EEG. METHODS: To determine 1 MAC, we studied sixty patients undergoing general anesthesia who were randomly allocated to receive isoflurane at several predetermined end-tidal concentration. A minimum of 15 min was allowed between induction and skin incision to allow steady state condition. Patients were observed for gross purposeful movement for 60 seconds after incision. The MAC was calculated using maximum likelihood solution to a logistic regression model. Another forty patients were randomly allocated to have their EEGs recorded. General anesthesia was induced with oxygen and isoflurane only. After loss of consciousness, succinylcholine 1.5 mg/kg was given and intubation followed. The EEG was recorded awake and after 15 min at steady state conditions of 1, 1.3 and 1.5 MAC isoflurane had been achieved. Spectral edge frequency 95% (SEF95), median spectral frequency (MSF), total power (TP) and relative power in the delta, theta, alpha and beta band were calculated. RESULTS: The MAC of isoflurane was 1.21 vol% (20 - 40 years) and 1.09 vol% (40 - 60 years). The distribution of spectral EEG indices of the EEGs were established and compared. The threshold value of SEF95 14 Hz to differentiate between arousal and 1.3 and 1.5 MAC had a sensitivity of 60.5% (1.3 MAC), 71% (1.5 MAC) and specificity of 74.4% (1.3 and 1.5 MAC) and that of MSF 5 Hz had a sensitivity of 71% (1.3 MAC), 81.5% (1.5 MAC) and specificity of 48% (1.3 MAC), 48.8% (1.5 MAC). CONCLUSIONS: With regard to the dose-related decrease in SEF95 and MSF under increasing end- expiratory concentrations of isoflurane as described in the present study, future studies may have todetermine whether EEG feedback control of volatile anesthetic administration may be used successfully. It seems that if neglected parts by MSF and SEF95, which are really true values are considered in the future studies, those would increase the sensitivity and specificity of EEG could be used as tool for determining depth of anesthesia.

BACKGROUND: Epidural analgesia is the most effective way of providing pain relief during labor.However, its effect on the second stage of labor is controversial.This study examined the effect of epidural analgesia combined with caudal analgesia on the second stage of labor. METHODS: Forty three multiparous women were divided into three groups, non-epidural group, epidural group and epidural with caudal group.Epidural analgesia was maintained with patient-controlled epidural analgesia (0.09375% ropivacaine with 0.0002% fentanyl) in both the epidural and epidural with caudal groups.The epidural with caudal group was injected with 0.09375% ropivacaine into the caudal epidural space after inserting the lumbar epidural catheter.The assessments made throughout labor included the visual analogue score (VAS), patient's satisfaction, motor block and duration of the second stage. RESULTS: There were no significant differences in the patient's satisfaction, VAS and motor block between the epidural group and epidural with caudal group.There were no significant differences in the duration of the second stage between the non-epidural, epidural and epidural with caudal groups. No cesarean or instrumental deliveries were performed. CONCLUSIONS: Epidural with caudal analgesia offers no additional benefit during the second stage of labor.However, it carries no added risk on the maternal outcome.

Hepatocellular carcinoma (HCC) is the third most common malignancy in Korea and the prognosis of patients with HCC is generally poor. Most patients with HCC have unresectable disease at presentation and only a small proportion of patients diagnosed early receive curative treatment. Transarterial chemoembolization (TACE) is a widely used palliative treatment for advanced HCC and its prognostic benefit has been proven in several studies. TACE is contraindicated for patients with portal vein tumor thrombosis (PVT) because it carries a potential risk of acute hepatic failure. Recently, however, a few studies have provided evidence of a survival benefit after TACE in patients with PVT if they have good hepatic reserve and collateral circulation around the portal trunk. We experienced a case of HCC with PVT, with long-term survival and no evidence of recurrence or hepatic failure after TACE, and present this case with a review of the relevant literature.

PURPOSE: The purpose of this study was to evaluate the efficacy of intrapleural chemotherapy (IPC) with cisplatin and cytarabine in the management of malignant pleural effusion (MPE) from non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: A prospective analysis was carried out on 40 patients with pathologically proven MPE from NSCLC who had received IPC. A single dose of cisplatin 100 mg/m2 plus cytarabine 1200 mg/m2 in 250 ml normal saline was instilled into the pleural space via a chest tube and drained 4 hours later. Patients were evaluated for toxicities and responses at 1, 2, & 3 weeks and then at monthly intervals if possible. Systemic chemotherapy was administered, if the patient agreed to receive it, after achieving complete control (CC) of MPE. RESULTS: The median duration of chest tube insertion for drainage was 7 (3~32) days. Among the assessable 37 patients, CC and partial control (PC) were 32 (86.5%) and 4 (10.8%) patients, respectively (overall response rate 97.3%). The median duration of response was 12 months (2~23) and there were only two relapses of IPC after achieving CC. Among the 35 patients who were assessable until they died, 28 patients (80.0%) maintained CC until the last follow-up. There was only one toxic death and the toxicities of IPC, versus the results obtained, were deemed acceptable. CONCLUSION: The procedures were tolerable to the patients and chemotherapy-induced complications were at an acceptable level. The outcome of this trial indicates that IPC has a superior and long lasting treatment response in the management of patients with MPE from NSCLC.
