PURPOSE: We report clinical charateristics of percutaneous central venous catheteriza- tion(PCVC) that is performed commonly as a vascular access procedure in the neonatal intensive care unit(NICU) including comparision between the success rate and com- plication rate of groups performed by a doctor and by nurses who were accustomed to the IV procedure. METHODS: We evaluated a total of 158 PCVC cases performed in the NICU of Soonchunhyang Chunan hospital over 2 years 5 rnonths from May, 1995 to September, 1997. The 24 cases of PCVC were performed by doctors and 134 cases of this proce- dures were performed by well trained nurses. We have compared success rates, clinical characteristics, insertion sites, indwelling time, causes of removal of the catheters, and associated complication of both doctor performed group (D) and nurse performed group (N) retrospectively. RESULTS: The mean gestational age, birth weight, weight at the time of insertion were significantly lower in the doctor performed group than in the nurse group(P<0.001). There were significant differences in postnatal age and mean duration per catheter in both groups. The overall success rate of insertions was 89.9%(142/158), the success rate of doctor performed group was 54.2%(13/24) and nurse group was 96.3%(129/134) and there was significant difference(P<0.001). In the doctor performed group, 100% were axillary however in the nurse group 43.4% were axillary, 38.8% were antecubital, 9.4% were temporal, and 5.4% were hand. The most common cause of the removal of the catheter was elective in both groups but there was also substantial spontaneous removal by the patients and mechanical complication. Cultures of catheter tips were done after removal in 110 cases, among then were positive in 36 cases(33.6%), the most common causes were Staphylococcus aureus and Candida albicans. CONCLUSION: In this report, the authors emphasize that percutanous central venous catheterization performed by well trained nurses has a higher success rates than the doctor performed group and can be considered safe. We would also like to emphasize that more attention should be paid to the maintanace of PCVC.

During the period from january, 1972, to march, 1979, Twenty-four patients underwent mitral valve replacement at the seoul national University Hospital. Their ages ranged from 8 years to 20 years, with 11 patients being 16 years of age or younger at the time of operation. There were 12 males and 12 females and their weight ranged from 25 to 53 Kilograms. Seventeen patients had advanced stages of heart disease as evidenced by the functional classification: 14 cases were in functional class III and 3 cases in functional class IV (New York heart Association). A history suggestive of rheumatic fever was elicited in 75 per cent of our patients. Radiographic evaluation demonstrated marked cardiomegaly in the majority of the patients. The cardiothoracic ratio was over 70 per cent in 5 patients and between 60 and 70 per cent in 17 patients. Cardiac catheterization was carried out in all patients before operation. There were 3 patients with evidence of severe pulmonary hypertension. In 2 patients the pulmonary artery pressures were normal. On physical and hemodynamic examinations, 3 patients had associated with aortic regurgitation, 2 patients had tricuspid regurgitation, 1 patient had tricuspid and aortic regurgitations and 3 patients had atrial septal defect or ventricular septal defect or transposition of great arteries. The pathologic findings of the mitral valve indicated rheumatic valvulitis in 16 patients, while in the remaining 7 the etiology was undetermined. In only one patient the cause was congenital cardiac anomaly. Seventeen patients had predominant mitral regurgitation and 7 patients predominant mitral stenosis. Twenty-nine cardiac prosthetic and bioprosthetic valves were replaced in 24 patients in the past 8 years. This series included 24 mitral, 4 aortic and 1 tricuspid valve replacement. Including in this group were patients who had concomitant aortic valve replacement(3 patients), tricuspid valve replacement(1 patient), tricuspide annuloplasty and closure of ventricular septal defect(1 patient), and closure of atrial septal defect and ventricular septal defec(3 patients). There were five deaths in the postoperative period, resulting in an operative mortality rate of 20.8 per cent. high postoperative mortality was seen in the patients with associated aortic valvular disease and congenital cardiac anomaly.

The vascular involvement is seen in 8% to 24% of patients with Behçet's syndrome. Arterial lesions are less frequently observed and the involvement of renal artery is very rare. Indeed, there is only one case report of ruptured renal aneurysm due to Behc et's disease. We report a case of renal artery rupture, which was likely caused by Behçet's disease. Even though we cannot completely rule out the other causes of renal artery rupture with this patient, the rupture was likely due to vascular involvement of Behçet's disease. Dermatologists always should consider the possibility of major vessel involvement when they treat patients with Behçet's disease, even if the incidence is very low and the patient may not complain of any systemic symptoms. INTRODUCTION: Behçet's disease was first defined by Hulusi Behçet's in 1937 as a multisystemic disease with the triad of recurrent aphthous stomatitis, genital ulceration and relapsing iritis. Its etiology remains obscure. It is accepted that the pathologic process of Behçet's disease is an immunologic vasculitis. Among vascilar lesions, the venous system is the major affected site. Arterial lesions, such as aneurysms or occlusions, are rarely reported, but sometimes adversely affects the course of the disease. Aneurysm formation is known to be life-threatening because of the risk of rupture.

The purpose of the study was to develop and evaluate the reliability of a semi-quantitative food frequency questionnaire (SFFQ) intended to measure mainly nutrient intake (energy, protein, fat, calcium and iron) related to growth in pre-schoolers in Korea. Based on foods with up to 90 cumulative percent contribution of the 5 nutrients, we developed a SFFQ for 86 foods. In order to evaluate the reliability of both nutrient and food intakes, caregivers of a sample of 101 children aged 4 to 6 years completed the SFFQ repeatedly at 3 month intervals. There were small differences in the nutrient intakes assessed by the SFFQ ranging from 0.55% to 9.91%. There were no significant differences in nutrient values calculated from the repeat questionnaires, except in the case of niacin and vitamin C. The Pearson correlation coefficients of most of the nutrients ranged form 0.54 to 0.75 (mean = 0.66). When energy intake was adjusted, there was approximately a 0.2 decrease in the correlation coefficient of most nutrients, due to the high correlation of energy intake with other nutrients (r=0.7-0.9). The amount of food intake differed by 0.1 to 66.4% (mean = 17.5%), depending on the food item. Out of 86 foods, 74 foods (86%) showed less than a 30% difference in intake and 30 foods (35%) showed less than a 10% difference. Only 6 (7%) out of the 86 foods presented statistically significant differences in intake. The Spearman correlation coefficients of most food intakes assessed repeatedly by the SFFQ ranged from 0.4 to 0.7. Reproducibility of the nutrient and food intakes found in this study was better or similar to those found in cases of Korean adults. Therefore, the SFFQ developed in the present study can be a useful tool to assess the dietary intake of pre-schoolers in Korea.

PURPOSE: Computed tomographic(CT), ultrasonographic(US) findings of solid and papillary epithelial neoplasm of the pancreas were correlated with pathologic findings for the better understanding of this disease entity. METHODS AND MATERIALS: A retrospective review of CT and US of 14 cases of solid and papillary epithelial neoplasm of the pancreas was carried out in terms of the margin, internal architecture, caicification and septation, and this was correlated with gross pathologic findings. RESULTS: CT and US findings were well defined round masses consisting of both solid and cystic components. Five cases were cystic, four cases were solid and five cases were mixed. Cystic portion of the tumor represented variable degree of hemorrhagic necrosis. Six cases contained foci of calcification, which were linear, marginal and amorphous. Marginal calcification interfered US examination of the mass in three cases. Internal septurn was demonstrated in four cases on CT, one case on US and three cases on gross specimen. CONCLUSIONS: Our results indicate that calcification and internal septurn were considered as a part of radiologic findings in solid and papillary epithelial neoplasm of the pancreas.
