Survey on sanitary knowledge level and degree of HACCP practice in culinary staff employed in elementary, middle, and high schools in Chungnam province / 한국영양학회지

PURPOSE: This study was performed to examine the sanitary knowledge level and degree of HACCP (hazard analysis critical control point) practice in school culinary staff in order to provide basic information for improving hygiene of school meals. METHODS: Exactly 305 culinary staff members were selected from elementary, middle, and high schools in 14 cities and rural areas, including whole administrative districts in Chungnam province. Surveyed schools were selected by convenience sampling, and one subject was selected randomly from each school. Surveys were taken by self-administered questionnaires developed by researchers and questionnaire were distributed and collected by postal mail. RESULTS: Sanitary education administered by school dietitians to culinary staff was more frequent and longer in elementary schools, followed by middle and high schools (p < 0.001). Sanitary knowledge level and degree of HACCP practice, except for a few CCP or CP of culinary staff, were highest in elementary schools and middle school followed by high schools (p < 0.05), respectively. School class was negatively correlated with sanitary knowledge level of culinary staff (p < 0.01), and frequen-cy of sanitary education was positively correlated with sanitary knowledge level of culinary staff (p < 0.01). Sanitary knowl-edge level of culinary staff was positively correlated with degree of HACCP practice (p < 0.01). School class, daily fre-quency of meal service, work experience, rice washing machine, and total score of sanitary knowledge were significant variables influencing degree of HACCP practice in culinary staff. CONCLUSION: The above results show that the following points should be considered to improve hygiene of school meals. Sanitary education should be administered more frequently by school dietitians to culinary staff, especially to those in high schools, which showed the lowest sanitary knowledge level and degree of HACCP practice. In addition, facilities and equipment required for HACCP practice should be supported in small-sized elementary schools.

Congenital Giant Left Circumflex Artery-to-Left Ventricle Fistula Detected Using Two-Dimensional and Doppler Echocardiography

Coronary arteriovenous fistula is a rare congenital coronary artery anomaly in adults. Most such fistula drain into a right heart chamber or into the pulmonary artery. Congenital left coronary artery-left ventricle fistula is even more uncommon. Aortography and selective coronary angiography are still the diagnostic mode of choice. However, recent studies have demonstrated that two-dimensional echocardiography with or without Doppler color flow imaging is a useful noninvasive tool in the diagnosis of coronary artery fistula. A 29 year-old female who had an exertional dyspnea, chest pain, and continuous diastolic murmur was referred to our hospital for further evaluation. The transthoracic two-dimensional and color Doppler echocardiography revealed a dilated left coronary artery which was drained into left ventricle. The coronary angiography showed that the left circumflex artery was very dilated and tortuous, and contrast medium passed from the left circumflex artery into the left ventricular cavity via a fistula. However, the right coronary artery and the left anterior descending artery were normal. We reported a case of an echocardiographically documented fistula between the left circumflex coronary artery and the left ventricle in young woman.

Menetrier's disease accompanied thrombosis of the iliac vein: A case report

Menetrier's disease is a rare cause of thickened gastric wall. The differential diagnosis of diffuse gastricwall thickening such as lymphoma and adenocarcinoma should be expanded to include Menetrier's disease. The authorsexperienced a case of Menetrier's disease accompanied deep vein thrombosis, which was proved by operation andpathology. We carried out double cntrast upper G-I series and computed tomography , and report with review ofliteratures.

Chest radiographic findings of leptospirosis

1. A study on chest radiographic findings of 54 cases with pneumonia like symptoms was performed. Of 54 cases,8 cases were confirmed to be leptospirosis and 7 cases were leptospirosis combined with Korean hemorrhagic fever.2. Of 8 cases of leptospirosis, 4 cases showed abnormal chest radiographic findings: acinar nodular type 2,massive cofluent consolidation type 2. Of 7 cases of leptospirosis combined with Korean hemorrhagic fever: acinarnodular type 3, massive confluent consolidation type1, and increased interstitial markings type 1 respectively. 3.It was considered to be difficult to diagnose the leptospirosis on chest radiographic findings alone, especiallythe case combined with Korean hemorrhagic fever.

Radiological evaluation of pulmonary metastasis

158 cases of pulmonary metastasis having satisfactory histological proof of the primary malignant tumor, the frequency and pattern of which were analysed by conventional radiologically. The results are as follows: 1. The frequency of pulomonary metastasis according to the primary sites was 24%(38/158) hepatobiliary system,19.6%(31/158) gastrointestinal tract, 18.9%(30/158) uterine cervix and 12%(13/158) head and neck. 2. Pulmonary metastatic pattern showed nodular type 74% (117/158), granular type 10.1%(16/158), streaky type 9.5%(15/158),hilar enlargement 3.8%(6/158), patchy type 1.9% (3/158) and others 0.6%(1/158). Of all these type, nodular type was predominant. 3. The nodular type of pulmonary metastasis was classified into less than 10 nodules56.4%(66/17), 10-50 nodules 25.6%(30/117), more than 50, 17.9%(21/117), less than 1cm 12.8%(15/117) and more than5cm in 5.2%(1/117) of the cases. 4. The size of nodule was 1-3cm 36.6%(43/117), 2-3cm 20.5%(24/117), less than 1cm12.8%(15/117) and more than 5cm in 5.2%(1/117) of the cases. 5. Most cases of pulmonary metastasis involved bothlung fields 69.2%(110/58). Others were right lung field only 17.7% (28/158), left lung only 12.7%(20/158). 6. Theages between 40 and 70 represented 79.8%(126/158) of the cases and the raio of male and female was about 1.5:1.

Radiologic Evaluation of Colorectal Cancer

The incidence of colorectal cancer of Korea is much lower than that of Western countries, but has shown a tendency to a slight increase recently Barium enema is the most valuable, noninvasive and inexpensive method available to evaluate the size, shape and site of colorectal cancer. The authors reviewed and radiologically classified barium enema studies of 232 cases of colorectal cancer from Aug. 1967 to July 1982 at Presbyterian Medical Center, Jeon-ju , Confirmed clinically, operatively and pat hologically. The results were as follows; 1. The ratio of male and female was 1.3:1, and youngest was 13 year-old and the oldest 86 year-old. 2. The peak incidence occurred from 5th to 7th decades, accounting for 78% of all cases (181/232), and there was a relatively high incidence of the disease in patients below 30 years of age at 7.8% (18/232). 3. Rectum and rectosigmoid region are the most frequently involved regions (127/23 2:54.8%). 4. The positivity of barium enema examination was 4.0% (232/5807), and its accuracy was 96.5% (224/232) . 5. The radiologic findings were classified into 4 groups, and they were annular encircling 62.9% (146/232), polypoid fungating 26.8% (62/232), infiltrating 8.6% (20/232), and primary ulcerating 1.7% (4/232) in order of frequency. 6. The linear length of the cancer ranged from 1.5 Cm to 15 Cm , and the average length was 5.5 Cm. 7. There was no statistical correlation between the length of lesion, the site, and the radiologic findings, and stages of the lesion (P:0.750-0.250). 8. The majority of colorectal cancers was adenocarcinoma (217/232:93.6%).
