This study was carried out to figure out the dietary intake of pregnant women in Daegu area. A total of 467 pregnant women was recruited at two hospitals in this area to collect the information on dietary intakes, general characteristics, and anthropometric measurements using an interview. Forty-seven women (10.1%) were in the first trimester, 101 women (21.6%) in the second trimester, and 319 women (68.3%) in the third trimester. The mean age, prepregnant weight and height of subjects were not significantly different among the trimester groups. The mean daily nutrient intakes of energy, fat, protein, carbohydrates, phosphate, sodium, vitamin B1, vitamin B2, and vitamin C were significantly different among the trimester groups, but the other nutrients were not different. For the calcium and iron, the percentage of subjects consumed less than 75% of the Korean RDA was over 80%, and for other nutrients such as energy, vitamin B1, and vitamin B2 over 50% of subjects consumed less than 75% of the Korean RDA in the first trimester. The correlations between nutrient intakes and weight gain during pregnancy showed different patterns among the trimester groups. The mean adequacy ratio and dietary variety scores were not significantly different among the trimester groups. The amount of food intake from cereals and cereal products were higher during the second and the third trimester compared to the first trimester, but those of the other food groups were not significantly different. In conclusion, nutrient intakes of the pregnant women for iron, calcium and some vitamins were inadequate and nutritional management programs for these nutrients are necessary.

Morning sickness during pregnancy is a very common functional problem with different kinds of symptom, but little data are available concerning the nutrition intervention program for pregnant women in local area. A total of 152 pregnant women who had experienced morning sickness were surveyed to investigate the relationships between morning sickness, nutrient intakes and pregnancy outcome. The results showed that prevalent symptoms were nausea (68.4%), heartburn (59.2%), morning sickness (48.7%), vomiting (42.1%), and constipation (44.7%). The onset of the symptom occurred during the first 3 months (9.3 +/- 2.3 weeks); 21.1% of the subjects was experienced two symptom at the same time. This significantly correlated with vomiting (p < 0.01), nausea (p < 0.001), morning sickness (p < 0.001), and heartburn (p < 0.01) with pregnancy weight. There were also correlations between the four symptoms and nutrient intakes. Mean birth weight of 21 newborns was 3.06 +/- 0.42 kg, and the one and five minutes of Apgar scores were 7.74 +/- 0.99 and 8.84 +/- 0.69, respectively. There were negative correlations between vomiting and pregnancy outcomes (p < 0.05). Our data support that morning sickness, especially vomiting during pregnancy is associated with Apgar score and body weight of newborn.

Here, we report a case of electrical injury-induced reversible advanced second-degree atrioventricular (AV) block. A 28-year-old male visited the emergency department for palpitations 3 days after receiving an electrical injury from 220 volt alternating current. The initial electrocardiogram (ECG) showed sinus rhythm and first-degree AV block with a prolonged PR interval of 400 ms. There was no structural heart disease or electrolyte imbalance. Follow up ECGs acquired 4-6 days after the electrical injury showed intermittent AV block with a prolonged PR interval of 400-460 ms. Exercise treadmill and atropine provocation tests performed 6 days after electrical injury induced advanced second-degree AV block. His bundle electrogram showed intermittent AH block in a Wenckebach pattern with a prolonged AH interval of 220-360 ms and a normal HV interval. Episodes of AV block decreased remarkably 4 weeks after the electrical injury, and the prolonged PR interval returned to 220 ms after 5 months.

L-asparaginase is an essential chemotherapeutic agent in the treatment of the acute lymphoblastic leukemia or non-Hodgkin lymphoma with its unique mechanism of action. It has many toxic effects involving multiple organs. The acute parotitis associated with L-asparaginase has been rarely reported. In this report, acute parotitis developed in the 4 acute lymphoblastic leukemia patients who were treated with the induction chemotherapy regimen including L-asparaginase. Mumps was excluded in 3 patients and the evidence of coexisting pancreatitis was observed in 2 patients. The parotid ultrasonography revealed diffuse enlargement in all patients. The symptoms were spontaneously resolved with no specific treatment, and in all cases there was no recurrence of the same disease with later maintenance chemotherapy including L-asparaginase. The possible mechanism of the acute parotitis is not yet clearly understood. But considering its histologic similarity with the pancreas, the depletion of L-asparagine may damage the acinar cells of parotid gland. The acute parotitis is not a well-known side effect of L-asparaginase but it needs to be promptly recognized in order to consider the discontinuation of the L-asparaginase and to exclude any viral infection requiring isolation.

Swyer-James syndrome (SJS) is characterized by a small- or normal-sized unilateral hyperlucent lung with decreased vascularity and air trapping on plain radiographs. SJS is considered to be a postinfectious form of bronchiolitis obliterans and has occurred following childhood pulmonary infection by adenovirus, measles, influenza virus, Bordetella pertussis, Mycobacterium tuberculosis or Mycoplasma pneumoniae. The standard treatment modality for SJS is supportive care. Despite the prominent role of inflammation in the pathogenesis of SJS, the use of corticosteroids has remained controversial. We report herein a case of SJS which was successfully treated with monthly methylprednisolone pulse therapy, resulting in complete remission as verified by high resolution computed tomography.

This study was aimed at development of a nutrition education program, which was designed for children, their parents and personnel in preschool nursery facilities and carried out by dieticians. The program was conducted at 6 preschool nursery facilities for 3 months from July to September 1998. Four-hundred thirty-three children aged 2 to 7 years were engaged in the program. Children in each class were given nutrition education practice once a week by dieticians using education materials and a guide book based on a 12-week program. The themes of nutrition education for children consisted of 'knowledge of food sources and foods', 'relations between food and health', 'other roles of food', 'right eating habit', and 'cooking practice'. Each of five leaflets on nutrition education for parents was delivered eery three weeks in a series and leaflets were posted on a bulletin board. Nursery school teachers were educated by their participation in the class with dieticians using education materials. Evaluation of nutrition education by children, parents and personnel was carried out by interviewing and using questionnaires before and after the program. Children responded more positively more positively on their eating behavior and sanitary behaviors after nutrition education. Parents'opinions on the nutrition education program were positive : 72.3 described the nutrition education program as 'very good'and 'good'. In addition, 71.3% answered that the education materials for parents were helpful. A majority(93.8%) of personnel in facilities evaluated the nutrition education program effective. Nursery personnel evaluated the importance of general nutrition knowledge, childhood nutrition, and obesity control for nutrition management and nutrition education more highly after nutrition education. This study indicates that nutrition management and nutrition education programs for preschool nursery facilities are necessary and they would be effective when implemented by dieticians.

Scatter radiation considerably affects radiographic image quality by reducing image contrast and contributing to a non-uniform background. Images containing a large portion of scatter radiation may result in an incorrect diagnosis. In the past few years, many efforts have been made to reduce the effects of scatter radiation on radiographic images. The purpose of this study is to accurately measure scatter fractions and evaluate the effectiveness of beam-stop arrays. To measure scatter fraction accurately, a beam-stop array and the SFC (Scatter Fraction Calculator) program were developed. Images were obtained using the beam-stop array for both an anti-scatter technique with an anti-scatter grid and an air gap technique. The scatter fractions of the images were measured using the SFC program. Scatter fractions obtained with an anti-scatter grid were evaluated and compared to scatter fractions obtained without an anti-scatter grid. Scatter fractions were also quantitatively measured and evaluated with an air gap technique. The effectiveness of the beam-stop array was demonstrated by quantifying scatter fractions under various conditions. The results showed that a beam-stop array and the SFC program can be used to accurately measure scatter fractions in radiographic images and can be applied for both developing scatter correction methods as well as systems.

OBJECTIVES: The Korean government has enacted two laws, namely, the Personal Information Protection Act and the Bioethics and Safety Act to prevent the unauthorized use of medical information. To protect patients' privacy by complying with governmental regulations and improve the convenience of research, Asan Medical Center has been developing a de-identification system for biomedical research. METHODS: We reviewed Korean regulations to define the scope of the de-identification methods and well-known previous biomedical research platforms to extract the functionalities of the systems. Based on these review results, we implemented necessary programs based on the Asan Medical Center Information System framework which was built using the Microsoft. NET Framework and C#. RESULTS: The developed de-identification system comprises three main components: a de-identification tool, a search tool, and a chart review tool. The de-identification tool can substitute a randomly assigned research ID for a hospital patient ID, remove the identifiers in the structured format, and mask them in the unstructured format, i.e., texts. This tool achieved 98.14% precision and 97.39% recall for 6,520 clinical notes. The search tool can find the number of patients which satisfies given search criteria. The chart review tool can provide de-identified patient's clinical data for review purposes. CONCLUSIONS: We found that a clinical data warehouse was essential for successful implementation of the de-identification system, and this system should be tightly linked to an electronic Institutional Review Board system for easy operation of honest brokers. Additionally, we found that a secure cloud environment could be adopted to protect patients' privacy more thoroughly.
