PURPOSE: This study examined the effect of hospitals' family-friendly management on married female nurses' retention intention. The focus was the mediating effects of the work-family interface (work-family conflict, work-family enrichment and work-family balance). METHODS: This study was a cross-sectional study. The participants were 307 nurses working at five public and five private hospitals with more than 200 beds in Seoul. Data were collected using structured questionnaires from September 10 to September 17, 2018 and analyzed with SPSS 24.0. Data were analyzed using an independent t-test, a one-way ANOVA, Pearson's correlation coefficients, and multiple regression following the Baron and Kenny method and Sobel test for mediation. RESULTS: There were significant correlations among family-friendly management, the work-family interface, and retention intention. Work-family conflict showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family enrichment showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family balance showed a partial mediating effect on the relationship between family-friendly management and retention intention. CONCLUSION These findings indicate that both hospitals' family-friendly management and nurses' work-family interface are important factors associated with nurses' retention intention. Therefore, hospitals should actively implement family-friendly management for nurses and establish strategies to enhance nurses' work-family interface for effective human resource management.

PURPOSE: The purpose of this study was to analyze the characteristic MR findings of childhood metachromatic leukodystrophy. MATERIALS AND METHODS: Five female patients (10--29 months old;mean age, 21.8 months) of biochemically confirmed metachromatic leukodystrophy were included in this study. We evaluated the extent of white matter degeneration, which was shown as high signal intensity on T2-weighted image, and the presence or absence of the enhancement. Result.' All 5 cases showed high signal intensity in periventricular deep white matter and centrum semiovale which were bilateral, symmetric and confluent. Posterior predominace, sparing of subcortical U fibers and immediate periventricular white matter, and the involvement of splenium of corpus callosum were also noted in all cases. There were other manifestations, such as 'tigroid pattern' in centrum semiovale (n=4), the involvement of genu of corpus callosum(n=4), posterior limb of internal capsule(n=4), descending pyramidal tracts (n=3), deep cerebellar white matter(n=1), claustrum(n=2), and diffuse brain atrophy(n=1). In three cases with Gd-infusion, contrast enhancement of the lesion was not seen. CONCLUSION: In childhood metachromatic leukodystrophy, MRI can clearly demonstrate the chracteristic extent of the white matter lesion and other associated findings, facilitating the differential diagnosis from other similar leukodystrophies.

PURPOSE: To present initial and follow-up HRCT findings of lymphangitic carcinomatosis of the lung. MATERIALS AND METHODS: Both initial and follow-up HRCT scans were obtained in 18 patients with lymphangitic carcinomatosis of the lung. After dividing the patients into two groups (with anticancer chemotherapy (n=12) and without chemotherapy (n=6), changes of pulmonary parenchymal abnormalities (percentile increase or decrease in the extent of each pattern) were assessed and compared on initial and follow-up HRCTs. RESULTS: Findings on initial CT were interlobular septal thickening (n=18) (smooth in 15 and mixed smooth and nodular in three), thickening of bronchovascular bundles (n=17), areas of ground-glass opacity (n=15), polygonal lines (n=15), and nodules (n=10). With chemotherapy, the finding of polygonal lines decreased by 20/3%, while findings of ground-glass opacity, bronchovascular bundle thickening, septal thickening, and nodules remained stable. Without chemotherapy, all CT patterns of abnormalities except nodules increased by 45-88%. In three patients who did not undergo chemotherapy, smooth interlobular septal thickening changed to nodular thickening. CONCLUSION: Lymphangitic carcinomatosis of the lung manifests initially as smooth thickening of the interlobular septae, bronchovascular bundle thickening,areas of ground-glass opacity, and polygonal lines, as seen on HRCT. Without chemotherapy, the extent of CT findings increases and there is a tendency for smooth septal thickening to change to nodular thickening. Chemotherapy induces improvement or cessation of the progression of CT findings.

BACKGROUND: More than 90% of dialysis patients respond in a dose-dependent manner to erythropoietin(EPO) administration and the others are resistant. The causes of EPO resistance are iron deficiency, vitamin deficiency, severe hyperparathyroidism, aluminum toxicity, and inflammation. Much literature has been published concerning iron deficiency and its role in EPO resistance. However little attention has been given to the contribution of inflammation to the EPO-resistant anemia observed in hemodialysis patients. METHODS: In the present study, we examined the contribution of parathyroid hormone levels, iron idices, normalized protein catabolic rate(nPCR), Kt/Vurea, albumin, and C-reactive protein(CRP) to erythropoietin resistance index(weekly rhEPO dose/body weight/hematocrit; ERI) in clinically stable 48 hemodialysis patients. RESULTS: The factors correlated with ERI were CRP(R=0.608, p< 0.01), ferritin(R=0.460, p< 0.01) and serum albumin(R=-0.359, p< 0.05). In stepwise multiple regression analysis, the independent factor affecting on ERI was CRP(beta=0.620, p< 0.01). Comparing high CRP group(> or =0.4 mg/dL) with normal CRP group(<0.4 mg/dL), there were significant differences in serum albumin, creatinine, ferritin, and ERI. CONCLUSION: Acute-phase response, assessed by the level of CRP, was the most important predictor or EPO resistance in stable hemodialysis patients.

Atrial flutter occurs most often in patients with organic heart disease. It appears that chronic atrial flutter is associated with a remarkably high risk of clinically apparent thromboembolism and effective anticoagulation appears to reduce this risk, but acute or recent onset, postoperative atrial flutter may have a lower risk of thromboembolism than those with chronic atrial flutter. In chronic atrial flutter or fibrillation with organic heart disease, anticoagulation is generally justified but there is some debate about anticoagulation in paroxysmal atrial flutter. The spontaneous echo contrast is generally accepted one of the major risk factor of thromboembolism and usually occurred in mitral stenosis, dilated cardiomyopathy, and enlarged left atrium, but rarely observed in apical hypertrophic cardiomyopathy. We experienced a patient with apical hypertrophic cardiomyopathy, who visited to emergency medical center due to dizziness and suffered from cerebral thromboembolism after restoration of sinus rhythm. In transesophageal echocardiography, there was moderate to severe spontaneous echo contrast in left atrium. This patient showed that transesophageal echocardiography evaluation of left atrium might be mandatory in patients with paroxysmal atrial flutter and organic heart disease.

Malignant fibrous histiocytoma, a type of sarcoma, is a malignant neoplasm with uncertain origin that arises in both the soft tissues and the bone. The occurrence of primary malignant fibrous histiocytoma of the pleura is extremely rare. We report a case of a 65-year-old Korean man who is being diagnosed with primary malignant fibrous histiocytoma of the pleura.

PURPOSE: To examine the effects of body position and time after feeding on gastric residuals in low birth weight infants(LBW). METHODS: A repeated measures design was conducted. Twenty LBW infants being fed via indwelling nasogastric tubes were randomly assigned to one of 5 different position orderings. In each position, gastric residuals were measured at 30, 60, 90, 120, 150, and 180 minutes after feeding. RESULTS: In comparisons of gastric residuals with position and time, the main effects of position and time were statistically significant (F = 5.038, rho = 0.001; F = 429.763, rho < 0.001, respectively), but the interaction between position and time was found not to be significant. In pairwise comparisons, the gastric residuals were more reduced in the right anterior oblique and prone positions compared with the left lateral position (rho < 0.05) and the differences across time periods were significant (rho < 0.001). CONCLUSIONS: The body position after feeding has a significant affect on gastric residuals over time in LBW infants. The right anterior oblique or prone position is recommended rather than left lateral position after feeding. Knowledge of the proper position and the pattern of gastric emptying over time after feeding may lead to the development of evidence-based nursing care.

The ovarian hyperstimulation syndrome is a rare but serious complication of ovulation induction therapy with gonadotropin. The clinical manifestations are generalized edema, ascites with pleural effusion and may become life-threatening in severe cases. The pathophysiology is still unknown therefore, the treatment should be symptomatic and conservative. We report a case of severe OHSS with massive right pleural effusion in excess of ten liters after human menopausal gonadotropin therapy because of secondary infertility. Fluid and electrolyte imbalances were corrected and albumin was administered. A right chest tube was placed for a total of sixteen days, draining eleven liters of pleural effusion totally, resulting a dramatic decrease of pleural effusion and improvement of symptoms.
