PURPOSE: The purpose of this study was to examine the effects of knowledge about the harmfulness of smoking and attitude toward smoking temptation for middle school students. METHODS: A survey was conducted in this study on 745 students from 12 middle schools in the Y City. Data were analyzed with SPSS/WIN 12.0 using descriptive statistics, t-test, ANCOVA, Scheffe's test and multiple regression analysis. RESULTS: There was statistically significant difference in knowledge about the harmfulness of smoking (F=2.88, p<.05) and attitude toward smoking (F=54.61, p<.001). And there was statistically significant difference in smoking temptations among tempting factors such as negative mood of individual (F=63.61, p<.001), positive mood of social situation (F=67.08, p<.001), habitualness (F=57.68, p<.001), weight control (F=33.01, p<.001), and others' smoking (F=73.13, p<.001). CONCLUSION: These results suggest that smoking-cessation programs to enhance the effectiveness of nursing interventions should be tailored to the level of smoking temptation and that educational programs should be developed for middle school students.

Thyroid dysfunction has heen reported as a side effect of alpha-interferon(IFN) therapy. The incidence of thyroid disorders was 1.2-12%' duripg 1FN therapy for chronic active hepatitis. We experienced a case of hypothyroidism developed after IFN therapy in a 48 year-old man with chronic hepatitis B. Baseline thyroid function before IFN therapy was normal and thyroid auioantibodies were also negative. High tiers ol' antimicrosomal antibody and anti-thyroglobulin antibody appeared and severe hypothyroidism followed at 6 months after starting the IFN therapy.

PURPOSE: To assess the clinical characteristics of the 2000-2001 measles outbreak in the Seoul metropolitan area, Korea, the clinical data of measles inpatients were analyzed. METHODS: Three hundred and five children diagnosed with measles by clinical manifestation from July, 2000 to February, 2001, in Seoul, Ilsan and Ansan City were grouped according to their age and investigated for clinical manifestations, vaccination history and measles-specific IgM/IgG antibody positivity. RESULTS: Thirty eight point seven percent of the subjects were less than 12 months of age, 27.5 % were 12-47 months of age and 33.8% were 48 months of age or older. There was no significant sexual difference(male : female=1.2 : 1). This epidemic started in June, 2000 and the number of patients increased abruptly in October, peaked in December and finally decreased after February, 2001. It started from the older age group and moved to the younger. Sixty five point two percent had a history of more than 1-dose vaccination and 13.6% of the patients equal or more than 48 months of age had a history of 2-dose vaccination. Primary vaccine failure rate was 59.4%(107/ 180) and secondary vaccine failure rate was 3.9%(7/180) in 1 dose vaccinees. Sixty one point six percent showed more than one complication and 38.4% had no complication. The most common complication was pneumonia(31.8 %), followed by bronchitis(11.5%) and acute otitis media(4.6%). Vaccination and dose were not related significantly with the occurrence of complications. CONCLUSION: Compared with previous outbreaks in Korea, clinical features showed no specific change in the 2000-2001 measles epidemic. However, primary vaccine failure rate was so high that the second vaccination at four to six years of age must be emphasized in Korea.

PURPOSE: The purpose of this study was to determine whether it is possible to differentiate benign from malignant thyroid nodules according to the proportion of sponge-like appearance within the nodules. METHODS: A total of 201 thyroid nodules containing sponge-like appearance from 195 patients (157 women and 38 men) were included this study. Each thyroid nodule was classified into one of three grades by real-time ultrasonography (US) based on the areas with a sponge-like appearance within nodule: grade I had sponge-like areas occupying <50%; grade II, between 50% and 75%; and grade III, >75%. We evaluated whether a correlation existed between these grades and cytopathologic diagnoses. RESULTS: Of the 201 nodules, 196 were benign and five were malignant, and according to the US classification, 101 nodules were grade I, 45 were grade II, and 55 were grade III. Of the five malignant nodules, four were grade I, and one was grade II. No statistically significant difference was found in the rate of malignancy between grade III and grades I and II, due to insufficient statistical power. A sponge-like appearance was correlated with follicles filled with colloid and cholesterol granules in benign nodules and with papillary fronds around the dilated cystic spaces in malignant nodules. CONCLUSION: No malignancies were found in thyroid nodules with >75% sponge-like appearance. Due to the overall low incidence of malignancy and the limited number of patients, a statistically significant difference could not be found in the prevalence of malignancy depending on the proportion of sponge-like areas within the nodule.

Serous cystadenomas of the pancreas are generally considered to be microcystic adenomas. Typical serous cystadenomas of the pancreas are encapsulated tumors composed of tiny cysts less than 2 cm in size showing sponge-like appearance with a central stellate scar or calcification on the cross-section. It has been recently reported, however, that serous cystadenomas may have macrocystic variants (major cysts more than 2 cm in size) that are radiologically indistinguishable from mucinous cystadenomas of the pancreas. We report the CT and MR imaging findings in a patient with mixed microcystic and macrocystic serous cystadenoma of the pancreas, indicating the histopathologic correlation. The mass was composed of two different types of cyst: multiple, small (<2 cm) with central calcification; and large (>2 cm) with peripheral calcification.

BACKGROUND: A variety of dermatological disorders develop in hospitalized patients and the need for dermatological consultations is on the rise. OBJECTIVE: We analyzed 2 years of dermatological consultation data from a tertiary medical center in Korea and compared dermatological problems among individual departments. METHODS: We reviewed 3,102 dermatological inpatient consultations by performing a retrospective chart review. RESULTS: Contact dermatitis (11.4%), drug eruption (9.6%), tinea pedis (5.5%), xerotic eczema (5.3%), and seborrheic dermatitis (5.2%) were the 5 dermatological disorders that were most commonly referred to dermatologists. Patients in the allergy and pulmonology departments had higher rates of drug eruptions. Endocrinology-admitted patients, especially diabetic patients, frequently complained of foot dermatitis. The cardiology, gastroenterology, and hemato-oncology departments referred many patients with purpuric dermatosis to dermatologists. Patients from the surgical departments consulted more frequently consulted contact dermatitis and drug eruptions. The neurology and rehabilitation medicine departments referred more seborrheic dermatitis patients than other departments. Pediatric patients commonly consulted for atopic dermatitis, viral exanthemata, and seborrheic dermatitis. Regardless of department, patients who suffered from severe illness and underwent major surgery developed herpes zoster and cutaneous fungal infections more frequently than other patients. Personal hygiene was closely related to the development of follicular disorders. CONCLUSION: Dermatologists should be familiar with the diverse dermatological complaints of patients admitted to various departments and be actively involved in the diagnosis, treatment, and education of doctors and patients to improve the quality of inpatient care.

Primary malignant lesions of the vagina are uncommon and represent approximately 1 -2% of all gynecologic malignancies. About 2% of all malignant vaginal lesions are primary sarcomas, the most common of these being leiomyosarcoma. We report the CT and MR imaging findings in a 41-year-old woman with vaginal leiomyosarcoma presenting as a bulky solid mass which caused expansion of the vaginal canal.

Medullary thyroid carcinoma (MTC) is a rare and challenging malignancy. In patients with residual MTC, the tumor detection rate is generally low for most of the currently available imaging techniques. Various imaging methods have already been used for the detection of residual tumor, but no modality has been shown to be superior to others. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has recently been proposed to identify residual MTC, but this procedure also has limitations as small masses are rarely detected. So, a multimodality imaging approach is recommended for detecting residual MTC. We report here on a case of residual MTC that was detected by 18F-FDG PET/CT in a patient with persistent hypercalcitoninemia after total thyroidectomy and bilateral lymph node dissection.

PURPOSE: To demonstrate a CT technique by which carcinoma of the ampulla of Vater can be more accurately diagnosed, and to describe the radiologic findings this carcinoma. MATERIALS AND METHODS: We retrospectively reviewed CT findings in 26 patients with pathologically proven carcinoma of the ampulla of Vater. One additional cup of diluted oral contrast medium was ingested immediately before the scan. We analysed the difference in detection rate of the mass in the duodenal lumen with and without duodenal luminal opacification of gastrografin.We also evaluated the size and shape of the mass, dilatation of CBD and the pancreatic duct, and lymph node metastasis. In addition, we analyzed multimodality imaging findings ultrasonogram (US) : 13; hypotonic duodenogram (HTDG): 7; ERCP : 17) of carcinoma of the ampulla of Vater. RESULTS: Nodular soft tissue masses protruding into the duodenal lumen were identified in 21 of 26 cases. In 95% of cases (21/22) with favorable opacification and distension of the duodenum, masses were clearly identified on CT imaging. However, in four caseswith poor opacification and distension of the duodenum, masses could not be observed(P=0.000). The mass on CT scanshowed a well-defined margin, round or lobulated contour, and contrast enhancement similar to that of thepancreas. CBD dilatation was identified in 20 cases and pancreatic duct dilatation in 12. On US, protruding massesin the distal CBD were observed in nine of 13 cases(60%) and on HTDG, in six of seven cases(86%). as well-definedfilling defects. Conclusion : Since the accuracy of CT diagnosis of intestinal lesions is directly proportional tothe degree of intestinal distension and opacification with oral contrast, we believe that adequate ct techniquefor distending and opacitying the duodeual lumen are necessary for early diagnosis of carcinoma of the ampulla ofVater.
