PURPOSE: This was a correlational study to identify effects of perception of clinical ladder system on job satisfaction and intention to leave in perioperative nurses. METHODS: Participants were 154 of perioperative nurses from larger general hospitals in Seoul. Data were collected from April, 16 to 22, 2013 using self-report questionnaires which included items on perception of clinical ladder system, job satisfaction, and intention to leave. Data were analyzed using frequency, t-test, ANOVA, Scheffe? test, Pearson correlation coefficients, and multiple stepwise regression. RESULTS: The average mean score for perception of clinical ladder system was midline at 2.69 point out of 4 point. Perception of clinical ladder system correlated positively with job satisfaction (r=.38, p<.01) and negatively with intention to leave (r=-.88, p<.01). Perception of clinical ladder system was the factor which most influenced job satisfaction explaining 17.1% of the variance, also perception of clinical ladder system was the factor which most influenced intention to leave, explaining 12.7% of the variance. CONCLUSION: Results of this study suggest that there is a need to enhance the perception of the clinical ladder system and to find ways to fulfill the expected effects for improving perioperative nurses' job satisfaction and reducing the intention to leave.

Previous studies reported the beneficial effect of erythropoietin (EPO) in acute injuries. We followed patients with and without acute kidney injury (AKI) after coronary artery bypass grafting (CABG) and evaluated the effect of EPO on long-term outcome. We also assessed the efficacy of urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a predictive marker of AKI. Seventy-one patients scheduled for elective CABG were randomly given either 300 U/kg of EPO or saline before CABG. The primary outcome was AKI, and the secondary outcome was the all-cause-mortality and composite of all-cause-mortality and end stage renal disease (ESRD). Twenty-one patients had AKI, 14 (66.7%) in the placebo group and 7 (33.3%) in the EPO group (P = 0.05). Also, uNGAL was higher in the patients with AKI than in those without AKI at baseline, 2, 4, 24, and 72 hr after CABG (P = 0.011). Among patients with AKI, 2-week creatinine (Cr) was not different from baseline Cr in the EPO group, but 2-week Cr was significantly higher than baseline Cr in the placebo group (P = 0.009). All-cause-mortality (P = 0.022) and the composite of all-cause-mortality and ESRD (P = 0.003) were reduced by EPO. EPO reduces all-cause-mortality and ESRD in patients with AKI, largely due to the beneficial effect of EPO on recovery after AKI.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Involvement of the gastrointestinal tract is seen in 3~34% of patients affected by this condition. Although the commonest sites involved are the sigmoid colon and rectum, only 4 cases have been reported in Korea. The most frequent symptoms are lower abdominal and pelvic pain typically worsening at the time of menstruation. Bleeding per rectum is uncommon since the mucosa is rarely involved. Endoscopy has not been thought to be helpful in the evaluation of patients with suspected colonic endometriosis. However, endoscopy is often used as the first test in patients with rectal bleeding, excluding malignancy or other sources of bleeding. There are few reports of endoscopic documentation of colorectal endometriosis. A 26 year-old woman having a history of endometriosis with cyclic hematochezia and lower abdominal pain is herein reported. A flexible sigmoidoscopy revealed a protrusion of hyperemic mucosa with a surrounding fold formation on the rectum 8 cm above the anal verge. The subsequent biopsy of the lesion gave rise to a diagnosis of endometriosis.

We evaluated the effect of cobalt chloride (CoCl2) on TNF-alpha and IFN-gamma-induced-inflammation and reactive oxygen species (ROS) in renal tubular epithelial cells (HK-2 cells). We treated HK-2 cells with CoCl2 before the administration of TNF-alpha/IFN-gamma. To regulate hemeoxygenase-1 (HO-1) expression, the cells were treated CoCl2 or HO-1 siRNA. CoCl2 reduced the generation of ROS induced by TNF-alpha/IFN-gamma. TNF-alpha/IFN-gamma-treated-cells showed an increase in the nuclear translocation of phosphorylated NF-kappaBp65 protein, the DNA-binding activity of NF-kappaBp50 and NF-kappaB transcriptional activity and a decrease in IkappaBalpha protein expression. These changes were restored by CoCl2. We noted an intense increase in monocyte chemoattractant protein-1 (MCP-1) and regulated on activation normal T cell expressed and secreted (RANTES) production in TNF-alpha/IFN-gamma-treated cells. We demonstrated that this effect was mediated through NF-kappaB signaling because an NF-kappaB inhibitor significantly reduced MCP-1 and RANTES production. CoCl2 effectively reduced MCP-1 and RANTES production. The expression of HO-1 was increased by CoCl2 and decreased by HO-1 siRNA. However, knockdown of HO-1 by RNA interference did not affect MCP-1 or RANTES production. We suggest that CoCl2 has a protective effect on TNF-alpha/IFN-gamma-induced inflammation through the inhibition of NF-kappaB and ROS in HK-2 cells. However, CoCl2 appears to act in an HO-1-independent manner.

OBJECTIVES: Asian migrant workers in Korea have various ethnicities. The purpose of this study was to evaluate the difference in spirometric interpretation made using the set of third National Health and Nutrition Examination Survey (NHANES III) reference equations and the relevant ethnicity-specific reference sets. METHODS: Spirometry was performed on 166 migrant and 498 Korean male workers between March and November 2012. We analyzed the spirometric data of healthy never-smokers. Spirometric patterns were evaluated using the NHANES III reference set and some relevant ethnicity-specific equations (Eom's equation for Koreans, Ip's equation for East Asians, Crapo's equation for Central Asians, Memon's equation for South Asians, and Gnanou's equation for Southeast Asian people). RESULTS: In all migrant groups except the Central Asian group, the forced expiratory volume in 1 second percentage (FEV1%) and forced vital capacity percentage (FVC%) calculated using each of the ethnicity-specific reference equations considered were significantly higher than those calculated using the NHANES III reference set. This study showed that in the evaluation of the spirometric result of subjects from Southeast Asia or South Asia, the percentage of cases with an abnormal FEV1 or FVC increased when the NHANES III set of equations was used as compared to when the ethnicity-specific equations were used. CONCLUSIONS: We found that the spirometric results of all ethnic groups were higher and the composition of the abnormal spirometric result was lower when the ethnicity-specific reference equations were used instead of the NHANES III reference set.

This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the IOL (n = 11), ocular hypertension (n = 4), focal posterior synechia (n = 4), hyphema (n = 3) and corneal ulcer (n = 2). The complications associated with the IOL were decenteration of the optic (n = 2) and ventral haptic displacement (n = 1). Most cases of PCO were found only around the margin of the IOL, and all eyes had vision during the observation period. In conclusion, the implantation of an acryl-foldable lens with a squared edge at the time of phacoemulsification is an effective method for preserving the central visual field of dogs with cataract.

Although central catheter-related complications are frequently reported and are inevitable in the neonatal care unit, the incidence of pericardiac tamponade is low but may be fatal. Index of suspicion, prompt diagnosis, and urgent pericardiocentesis are crucial for lifesaving. We encountered two premature cases of central venous catheter-related pericardial tamponade. The first case was a 4-day-old male premature infant (gestational age [GA], 33(+5) weeks; birth weight [BW], 1,864 g), and the second case was a 4-day-old female premature infant (GA, 28(+6) week; BW, 1,050 g). Each infant had an indwelling central venous catheter since birth and at the third day of hospitalization. The conditions of the babies suddenly deteriorated, but both babies were successfully resuscitated with urgent echocardiography and prompt pericardiocentesis.

Spontaneous intramuscular hematoma of the abdominal wall is a rare condition characterized by acute abdominal pain. It is often misdiagnosed as a surgical condition. It used to be associated with risk factors such as coughing, pregnancy, and anticoagulant therapy. Most cases of abdominal wall hematomas were rectus sheath hematomas caused by the rupture of either the superior or inferior epigastric artery, but spontaneous internal oblique hematoma was extremely rare. In this report, we present a case of spontaneous internal oblique hematoma in a 69-year-old man with non-dialysis chronic kidney disease who was taking cilostazol. The patient complained of abrupt abdominal pain with a painful palpable lateral abdominal mass while sleeping. The abdominal computed tomography showed an 8 cm-sized mass in the patient's left internal oblique muscle. The administration of cilostazol was immediately stopped, and the intramuscular hematoma of the lateral oblique muscle disappeared with conservative management.

Angiotensin II type 1 receptor blocker (ARB), which is frequently prescribed in patients with glomerulonephritis (GN), is suggested to increase the risk of cancer. We registered 3,288 patients with renal biopsy and analyzed the relationship between the use of renin-angiotensin-aldosterone system (RAAS) blockade and the incidence of cancer or cancer mortality. After renal biopsy, cancer developed in 33 patients with an incidence rate of 1.0% (95% of CI for incidence: 0.7%-1.3%). There was no difference in the cancer incidence among the groups according to the use of angiotensin-converting enzyme inhibitors (ACEI) or ARB: 1.2% in the None (23/1960), 0.7% in the ARB-only (5/748), 0.4% in the ACEI-only (1/247), and 1.2% in the ACEI-ARB (4/333) (P = 0.487) groups. The cancer mortality was 2.1%, 0.4%, 0.0%, and 0.3% in None, ACEI-only, ARB-only, and ACEI-ARB group, respectively (P < 0.001). The risk of cancer mortality in patients with ARB was only 0.124 (0.034-0.445) compared to that of non-users of ARB by Cox's hazard proportional analysis. In conclusion, prescription of ACEI or ARB in patients with GN does not increase cancer incidence and recipients of ARB show rather lower rates of all-cause mortality and cancer mortality.
