Purpose: : This study aimed to examine the effects of the awareness of patient safety culture, emotional labor, and job stress on patient safety nursing activities by comprehensive nursing care medical service ward nurses. Methods: : The participants were 112 nurses from the comprehensive nursing care service wards from six hospitals. Data were collected using structured questionnaires and analyzed using a t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple regression analysis using SPSS version 20.0. Results: : The factors that significantly influenced patient safety nursing activities in the comprehensive nursing care medical service ward nurses included job stress (β=-0.18, p<.032) and awareness of patient safety culture (β=0.54, p<.001). The explanatory power of these factors was 31.0% (F=13.43, p<.001). Conclusion : This study showed that the factors that influenced patient safety management activities of comprehensive nursing care medical service ward nurses included job stress and awareness of patient safety culture.

To evaluate the potential contribution of high resolution ultrasonography(US) and 99mTc scintigraphy in the routine diagnosis of thyroid nodules, we performed thyroid function tests, US, thyroid scintigraphy, and fine-needle aspiration cytology (FNAC) in all 54 patients who initially visit our surgical department for thyroid masses from March 1995 to February 1996. The final diagnoses were made by either repeated FNAC (n=39) or thyroid operations (n=15). Final diagnoses were adenomatous goiters (n=41), simple cysts (n=3), follicular adenoma (n=1), papillary carcinomas (n=8), follicular carcinoma(n=1). The diagnostic impacts of US and 99mTc scintigraphy in all 54 patients were assessed and scored according to the following criteria: when the information provided by either test supported or confirmed (and/or gave some other information for management of thyroid nodules) the final diagnosis, it received a scores of 2 or 3 respectively, while a score 1 was given when the test itself was useless for the differential diagnosis. The scores of US were higher than those of scintigraphy in the diagnoses of adenomatous goiters, cysts, adenomas and carcinomas. However, after statistical analysis with Wilcoxon's signed rank test, US was statistically superior to scintigraphy only in diagnosing adenomatous goiters. These results indicate that current findings in US for differential diagnosis of thyroid nodules are not absolutely superior to those in scintigraphy, but have some benefits in detection of occult nodules in malignancy and differential diagnosis of adenomatous goiters.

In the light of experimental results, two case-control studies and one cohort study in a population of ginseng cultivation area were conducted to confirm whether ginseng has any anticarcinogenic effect on human cancers. All participants were interviewed using a standardised questionnaire to obtain the information on demographics, cigarette smoking, alcohol consumption and ginseng intake. In 905 pairs case-control study, 62% had a history of ginseng intake compared to 75% of the controls, a statistically significant difference (p<0.01). The odds ratio (OR) for cancer in relation to ginseng intake was 0.56. In extended case-control study with 1987 pairs, the ORs for cancer were 0.37 in fresh ginseng extract users, 0.57 in white ginseng extract users, 0.30 in white ginseng extract users, 0.30 in white ginseng powder users, and 0.20 in red ginseng users. Those who took fresh ginseng slices, fresh ginseng juice, and white ginseng tea, however, did not show decrease in the risk. Overall, the risk decreased as the frequency and duration of ginseng intake increased. With respect to the site of cancer, the ORs for cancers of the lip, oral cavity, pharynx, esophagus, stomach, colorectum, liver, pancreas, larynx, lung and ovary were significantly reduced by ginseng intake. Smokers with ginseng intake showed lower ORs for cancers of lung, lip, oral cavity and pharynx and liver than those without ginseng intake. In 5 yr follow- up cohort study conducted in the ginseng cultivation area, Kangwha-eup, ginseng intakers had significantly lower risk than non-intakers. As for the type of ginseng, cancer risk significantly decreased among intakers of fresh ginseng extract, alone or together with other ginseng preparations. Among 24 red ginseng intakers, no cancer death occurred during the follow-up period. The risk for stomach and lung cancers was significantly reduced by ginseng intake, showing a statistically significant dose-response relationship in each follow-up year. In conclusion, Panax ginseng C.A. Meyer has been established as non-organ specific cancer preventive, having dose response relationship. These results warrant that ginseng extracts and its synthetic derivatives should be examined for their preventive effect on various types of human cancers.

BACKGROUND: Hypothyroidism may be involved in a significant portion of the causes of hypercholesterolemia in Korea. In this study, we determined the frequency of suspected hypothyroidism in hypercholesterolemic patients and compared the frequency of elevated thyrotropin levels among the groups with various total cholesterol levels. METHODS: The study subjects were healthy, asymptomatic people who visited Health Promotion Center of Seoul National University Hospital. We excluded subjects with history of hypertension, DM and hypothyroidism. The study subjects underwent physical examination and filled out a questionnaire on health risk factors. Also blood chemistry and thyroid function test were done. RESULTS: Among 6479 subjects, 194(2.99%) had elevated(>4.1 microIU/ml) thyrotropin levels. Among the hypercholesterolemic(> or=240mg/dl) patients(n=868), 40(4.60%) had elevated thyrotropin levels. And there was statistically significant difference between normal cholesterolemic and hypercholesterolemic subjects(P<0.05). Among the patients with total cholesterol above 280mg/dl (n=180), 15(8.33%) had elevated thyrotropin levels. As amount of the total cholesterol increased, the frequency of elevated thyrotropin levels Increased(P=0.001). And this result was consistent following adjustment for age, sex, BMI, smoking and drinking status(P<0.01). CONCLUSIONS: Practicing physicians should be aware of the possibility of secondary hypercholesterolemia due to hypothyroidism and keep in mind the importance of evaluating TSH level.

PURPOSE: Current evidence indicates that ultrasonography of the breast is an important adjunct to mammography and clinical examination in the diagnosis of palpable breast abnormalities. An assessment of the value of office-based ultrasonography of a palpable breast mass performed by a breast surgeon was the aim of this work. METHODS: A 7.5 MHz linear probe was used to perform office-based ultrasonography in 109 consecutive female patients having a palpable solid breast mass between August 1998 and December 1999. Breast masses diagnosed histologically as fibroadenomas or breast cancer were included in this study. The clinical impression from the physical examination (PE), the result of officed-based ultrasonography done by a surgeon (OUSG), and comprehensive judgement engaging both PE and OUSG (PEUSG) were recorded in each patient's hospital record as benign or malignant at the first visit. The diagnostic values of PE, OUSG, PEUSG, mammography (MMG), and ultrasonography done by a radiologist (USG) were compared. RESULTS: Of 109 masses, a fibroadenoma was diagnosed in 73 patients while a carcinoma was established in 36 patients. The sensitivity, the specificity, the accuracy rate, and the kappa coefficient were 91.7%, 89.0%, 89.9%, and 0.780 for PE; 100%, 90.4%, 93.6%, and 0.862 for OUSG; 97.2%, 97.3%, 97.2%, and 0.938 for PEUSG; 90.4%, 89.4%, 90%, and 0.630 for MMG; and 88.9%, 90.9%, 90% and 0.798 for USG. The diagnostic accuracy of PEUSG was significantly higher than those of PE and MG (p<0.05). CONCLUSION: These data suggest that office-based ultrasonography of the breast performed by a surgeon is a useful adjunct to clinical evaluation of the breast mass and permits timely and cost-effective patient care.

Authors presented the serial changes of brain MRI findings in two cases of cryptococcal meningitis. The MRI findings of the first patient (53-year-old female) consisted of dilated Virchow-Robin spaces, leptomeningeal enhancement, cryptococcomas and hydrocephalus. Dilated Virchow-Robin spaces were noted on the first MR obtained 33 days after symptom onset. The size and number of dilated Virchow-Robin space gradually decreased since 119 days after symptom onset (62 days after treatment). Faint leptomeningeal enhancement was found at cerebellar region on the first MRI, which became more distinct and intense on the day 119, probably due to improper treatment. The leptomeningeal enhancement decreased on the day 156. Mild hydrocephalus was noted on MRI obtained 70 days after symptom onset, which markedly aggravated on the day 119. It decreased after steroid therapy alone. Enhancing crytococcomas of variable size were noted at the right temporal lobe and cerebellum on MRI of the day 119, which decreased in size and number on the day 156. On the day 295 MRI showed nearly disppearance of the dilated Virchow-Robin space, but faint leptomeningeal enhancement, cerebellar crytococcomas and hydrocephalus still remained. The MRI findings of the second patient (36-year-old female) showed the findings similar to those of the first patient. Initial MRI obtained 18 days after symptom onset showed no abnormal findings. Dilated Virchow-robin spaces were noted on the day 36 (13 days after treatment onset), which nearly disappeared on the day 109. Enhancing cryptococcomas in both basal ganglia and cerebral cortex and leptomeningeal enhancement were noted on MRI of the day 136. Both cryptococcomas and leptomeningeal enhancement decreased in size and enhancing degree on the day 157. Hydrocephalus was noted on the day 109.
