Knowledge of Stroke and Heart Attack Symptoms and Risk Factors Among Rural Elderly People: A Questionnaire Survey

BACKGROUND AND OBJECTIVES: To determine the level of knowledge of stroke and heart attack (HA) symptoms and risk factors of cardiovascular disease (CVD) in rural elderly people who are at risk for CVD. SUBJECTS AND METHODS: A total of 444 adults over the age of 60 living in a rural province of Korea with at least one CVD risk factor participated in this survey. RESULTS: A total of 72.5% of the participants had hypertension and 28.4% had diabetes, whereas approximately 40% exhibited over two CVD risk factors. The mean knowledge scores for HA symptoms (4.3/9) were lower than scores for stroke symptoms (5.8/9), and the mean knowledge score for risk factors was 7.3/11. Stepwise multiple regression analyses showed that old age, low level of education, and low income level were the determining factors for low knowledge levels of stroke and HA symptoms as well as CVD risk factors. A low perceived risk of stroke or HAs also predicted a low knowledge of CVD risk factors. CONCLUSION: Community-wide public campaigns are needed, which are designed to help elderly people in rural areas with low education levels and socioeconomic status at risk for CVD to improve the awareness of stroke and HA.

The Histological Study of Accessory Tragus: A Comparison of Vertical Sections with Transverse Sections

BACKGROUND: Accessory tragi contain a central core of cartilage, which is the most important pathological factor, but often are misdiagnosed as soft fibroma/hair follicle nevi if sections cannot show a central core of cartilage. OBJECTIVES: The purposes of this study were aimed at comparing transverse sections with vertical sections and demonstrating the value of transverse sections about histological diagnosis for accessory tragus. METHODS: We studied 14 cases of patients with accessory tragi. All cases were totally excised and all 16 biopsy specimens (bilateral in 2 cases) were obtained. We classified these biopsy specimens into two groups regarding the removal of cartilage.All specimens were vertical or transverse seiral sectioned and we compared these histologic findings with established histologic diagnostic criteria which Satoh et al. reported. RESULTS: On the specimens of group 1 in which there was cartilage, subcutaneous prominent connective tissue framework whirling around cartilage could be observed on all transverse sections, but was not always present on vertical sections. Prominent connective tissue framework and pilosebaceous units with circular arrangement of eccrine glands were simultaneously in the center of transverse sections regardless of the presence of cartilage. CONCLUSIONS: In this study, transverse sections showed all diagnostic histologic important features for accessory tragus: presence of central cartilage, prominent subcutaneous connective tissue framework, and various degree of pilosebaceous unit, especially with circular arrangement of eccrine glands. So transverse sectioning could be a useful method for accurate histological diagnosis of accessory tragi regardless of the removal of cartilage when doing excisional biopsy.

Fine Needle Aspiration Cytology of the Breast Lesions: Application of the Masood's Scoring System / 대한세포병리학회지

Fine needle aspiration cytology is considered as a useful diagnostic procedure in management of patients with breast lesions. This study was undertaken to evaluate the scoring system of Masood in the interpretation of breast aspirates, to establish the most useful cytologic criteria for the diagnosis of breast lesions, and to subclassify the benign breast diseases. To assess the feasibility of a cytologic grading system, 57 cases of benign breast disease, 61 cases of malignant breast disease were studied, respectively. The aspirates were evaluated for the cellular arrangement, the degree of cellular pleomorphism and anisonucleosis, and the presence of myoepithelial cells and nuceoli. Values ranging from 1 to 4 were assigned to each criterion and the sum of the individual values was made for each case. The presence of stroma, apocrine metaplasia, foamy histiocytes and inflammatory cells, background of the smear, and cellularity were also evaluated. Cut-off value of the scoring system of Masood between benign and malignant lesion was 15. Among the cytologic criteria, cellular arrangement, presence of myoepithelial cells, nucleoli, and stroma, status of chromatin pattern, and background of smear were useful criteria in the differentiation between benign and malignant lesions. Application of the scoring system of Masood does not always make the accurate diagnosis and the subclassification of benign breast disease.
