PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

Agenesis of the dorsal pancreas is one of the rare congenital anomalies of the pancreas. Six cases of them have been reported. We have experienced an autopsy case of agenesis of the dorsal pancreas associated with fetal death in the uterus. Grossly, the body and tail of the pancreas and uncinate process were not found and those were partially replaced by adipose tissue. No abnormality was noted in the other organs. Microscopically, pancreatic tissue with autolytic change was identified only in the head portion of the pancreas.

PURPOSE: The purpose of this study was to provide data to establish an efficient manpower management plan so that the organization can identify the influence of organizational silence and professionalism on job embeddedness among nurses in hospital management. METHODS: Self-report questionnaires were distributed to 150 nurses in hospital management who were working in general hospitals with less than 900 beds but more than 300 beds in the districts of Seoul and Gyunggi, Gangwon province. Of the questionnaires, 127 out of 150 copies were collected and 120 copies were used for final analysis. Seven were not considered sincere in the responses. Data were analyzed using SPSS ver. 22.0 statistic program, t-test, ANOVA, Scheffé test, Pearson correlation coefficients and multiple regression. RESULTS: Organizational silence and professionalism had significant influence on job embeddedness, which explained 43.4% of job embeddedness. CONCLUSION: The results indicate that in order to raise job embeddedness, it is necessary to provide various programs to change communication patterns in the nurses in hospital management, and to create environments in which nurses in hospital management can present various opinions.

Alveolar crest is the section of interproximal alveolar bone which includes the free edge of the alveolar process. An increase of the normal forces within limits of tolerance leads to deposition of new bone. If forces are beyond the limits of tolerance, resorption of bone will result whether the force produces pressure or tension. This study was designed to evaluate changes of alveolar bone levels in mesial and distal surface of the left, right first molar, by using pre-treatment, post-treatment panorama films. Two hundreds sixteen subjects were divided into adolescent group of 104 subjects and adult group of 112 subjects, to which orthodontic treatment with a bicuspid extraction (adolescent group-50 subjects, adult group-50 subjects) or without a nonextraction (adolescent group-54 subjects, adult group-62 subjects) was applied by fixed appliances. Pre- and post-treatment panorama films were traced, and alveolar crest height was measured. Amounts of changes in alveolar crest height by treatment were calculated and compared in terms of side of tooth, extraction, age. The results were as follows; 1. When pre-treatment alveolar crest bone levels were compared, levels of adult group were significantly lower than those of adolescent group. 2. Post-treatment alveolar crest bone levels were significantly lower than pre-treatment levels. 3. When changes of alveolar crest height were compared, between adolescent and adult group were not significantly. 4. When changes of alveolar crest height were compared, significantly larger changes were noticed in extraction than nonextraction cases. 5. When changes of alveolar crest height were compared, significantly larger changes were noticed in maxilla than mandible. 6. When mesio-distally compared, significantly larger changes were observed in the distal than mesial sides of adult group.

BACKGROUND: Vascular endothelial dysfunction (VED) plays a pivotal role in the pathogenesis of atherosclerosis and is associated with insulin resistance and with visceral obesity. Therefore, in this study the predicting factor of vascular endothelial dysfunction was investigated in healthy premenopausal obese women by pulse-wave analysis (PWA) combined with provocative pharmacological testing. METHODS: Thirty three obese women (BMI> or =25), aged 20~45 y and 25 age-matched control subjects (BMI; 18.5~22.9) were examined. All women were sedentary (<1 hr/wk of physical activity), non-smoker and were excluded if they had type 2 diabetes melitus, hypertension, hyperlipidemia, cardiovascular disease, or acute inflammatory disease and were studied in folicullar phase of the cycle, within the first week after cessation of menstrual bleeding. They underwent determination of anthropometric measurements, metabolic variables, adipose tissue regional distribution, and endothelial function by performing pulse-wave analysis (PWA) combined with provocative pharmacological testing. RESULTS: Augmentation Index (AIx) fell significantly after the administration of salbutamol, which causes endothelium-dependent vasodilatation, but response was significantly reduced in obese women compared with controls (10.28 6.72% vs 17.2 6.84%, P=0.0003). The change in after Nitroglycerin, which causes endothelium-independent vasodilatation, did not differ significantly (30.86 9.67% vs 30.6 10.11%, P=0.9172). In our obese subjects, visceral adipose tissue area was independently a significant predictor of vascular endothelial dysfunction (beta= 0.1381, P=0.0038, Adj-R2=0.348). CONCLUSION: Increased abdominal adiposity is a powerful independent predictor of VED in obese healthy women. Future studies of vascular endothelial function should account for the independent effects of abdominal fat.

PURPOSE: The main purpose of this study was to investigate the modalities children with atopic dermatitis. METHODS: The data were collected from 933 children ages under 12 years who were diagnosed with atopic dermatitis for over 1 year. RESULTS: Moisturizer was the most frequent prescription from hospitals and immune modulator was the most satisfactory therapy. The most common cause of non-compliance was the concern about the side effects of drug such as steroid. In addition, 71.5% of children reported previous or current use of alternative therapy and most common source of information on alternative therapy was from mass media. CONCLUSION: Various therapies have been utilized to manage atopic dermatitis and the use of alternative therapy is in common in Korea. It is suggested for all care providers to be more aware of alternative therapies.

BACKGROUND: Many studies have demonstrated that nitrous oxide diffuses into the cuffs of endotracheal tubes and increases cuff volumes and pressures. Such increments of cuff pressure maybe result in damage to the trachea. We evaluated the increase of intracuff pressure, volume and the statistical significance was analyzed with personal computer. METHODS: Fourty-nine patients ranging in age 37+/-15 years, in ASA physical status class 1~2 , they were 26 males and 23 females. They divided into two groups, group I(n=25) were anesthesia with nitrous oxide : oxygen (2 L/min : 2 L/min), group II were(n=24) anesthesia with nitrous oxide : oxygen (4 L/min : 2 L/min). The cuff pressure was measured every 30 minutes and compared with each others and group I and II. RESULTS: Our results suggest that a significant intracuff volume and pressure changes developed between two groups (p<0.05), more significant intracuff pressure changes occured at group II than group I (p=0.001) and significant increment changes according to time and different concentration of nitrous oxide between two groups (p<0.05). CONCLUSIONS: This study was conducted to determine the degree of intracuff pressure and volume changes during general inhalation anesthesia with different concentration of nitrous oxide. These results suggest that a nitrous oxide significantly increases cuff pressure and volume in a concentration and time related fashion.
