Cardiac arrest associated with hyperkalemia during red blood cell transfusion is a rare but fatal complication. Herein, we report a case of transfusion-associated cardiac arrest following the initiation of extracorporeal membrane oxygenation support in a 9-month old infant. Her serum potassium level was increased to 9.0 mEq/L, soon after the newly primed circuit with pre-stored red blood cell (RBC) was started and followed by sudden cardiac arrest. Eventually, circulation was restored and the potassium level decreased to 5.1 mEq/L after 5 min. Extracorporeal membrane oxygenation (ECMO) priming is a relatively massive transfusion into a pediatric patient. Thus, to prevent cardiac arrest during blood-primed ECMO in neonates and infants, freshly irradiated and washed RBCs should be used when priming the ECMO circuit, to minimize the potassium concentration. Also, physicians should be aware of all possible complications associated with transfusions during ECMO.

Many patients complain of near vision difficulty after PRK surgery. In the prospective study, we report the effect of PRK surgery for myopia on accommodation and binocular vision. 45 myopic eyes (39 patients, 9 males, 30 females) underwent PRK for myopia. Mean preoperative amplitude of accommodation in moderate degree myopia (group 1 < OR = -6.00D in shperical equivalent : range -2.45 ~ -6.00D) was 7.01+/-1.25D, mean preoperative amplitude of accommodation in high degree myopia (group 2 > -6.00D in spherical equivalent : range -6.10 ~ -10.75D) was 6.85+/-1.41D. Mean postoperative amplitude of accommodation of group 1 was 8.13+/-1.38D, mean postoperative amplitude of accommodation of group 2 was 7.80+/-1.33D, the difference of both groups were statistically significant(p>0.05). Mean preoperative amplitude of accommodation of all patients was 6.91+/-1.35D, mean postoperative amplitude of accommodation was 7.93+/-1.36D, the difference are statistically significant (p>0.01). 12 of 39 patients complained of near vision difficulty while reading after PRK surgery on their one eye, but 3 of them who underwent PRK surgery on their the other eye noticed the disappearance of near vision difficulty. Stereopsis was tested and 15 of 36 patient lost more than 50 sec/arc of streoacuity. Near vision difficulty was not related to the amount of myopia corrected, not related to the stereoacuity change but seemed to related to their adaptability or their reaction time of accommodation with their operated eyes.

Fetal echocardiography is used by means of decleration of fetal cardiac anaztomy, to estabilish the diagnosis of congenital heart disease in utero. We attemped fetal echocardiography to ninty three pregnant women after intra uterine period 24 weeks, and estimated cardiac circumference, cardiac axis, pulmonary atery root diameter, arortic root diameter, diameter of inferior vena cava, diameter of superior ve studied how these estimates associate with following gestational na cava, and fractional shortening of ventricles. We ages. Cardiac axis was on the average 37.28 degree and cardiac apex was located in anterior left side of chest area. Aortic root diameter was 0.227 GA-0.043mm (GA=gestational age) at systolic phase, 0.203 GA+0.421mm at diastolic phase. Pulmonaly root diameter was 0.271 GA-0.029mm at systolic phase, 0.251 GA-0.067mm at diastolic phase. Thoracic aorta diameter was 0.195 GA+0.109mm at systolic phase, 0.198 GA+0.794mm at diastolic phase. Fractional shortening was 0.24 (1 Standard Deviation=0.11) in right ventricle, 0.23(1 SD=0.154) at left ventricle, and so ratio of right and left ventricle was 1.04(1 SD=0.51). Once normal fetal cardiac anatomy is understood, structural defects and/or alternation of function can be evaluated antenatally.

OBJECTIVES: This study was conducted to examine the mental health status of the laid off by comparing the unemployed with the employed. METHODS: A survey questionnaire was used to investigate the mental health status of the laidoff in comparison with that of the employed. The study sample consisted of 247 laid-off people formerly employed in A auto factory and 167 employees working in B auto factory. RESULTS: The proportion exercising regularly was 20.2% for the laid-off and 34.8% for the employed and the proportion having regular meals was 10.9% and 50.6%, respectively. In addition, the frequency and amount of alcohol consumption and smoking of the laid-off were higher than those of the employed. Among the laid-off, 69.4% responded that they spent less time in talking to their spouse, and 65.4% also reported reduced sexual activities with their spouse. Because of unemployment, 41.8% of the laid-off experienced conflicts with their children, and 53.5% also perceived that they were stigmatized and treated badly by their neighbors, friends and relatives. Mean IFR in the laid-off was 22.9, which was much higher than the 15.3 recorded in the employed. The mean PWI-SF was 24.2 for the laid-off and 13.0 for the employed, which indicates the lower psychological health status of the laid-off than that of the employed. Age, annual salary, family relationship, regular exercise, regular diets, possibility to return to work and perception of the future were related to mental health status for the laid-off. Stepwise multiple regression analysis showed that the most important factor influencing mental health status for the laid-off was family relationships. CONCLUSIONS: According to the above results, the mental health of the laid-off is worse than that of the employed. Based on this study, a follow-up study focusing on the mental health status of the reemployed to the same factory, is needed to understand the direct mental health effect on the laid-off.

A 60-year-old woman has experienced of right upper quadrant abdominal discomfort. This partient took cholecytectomy due to gall stone 15 years ago. At that time microscopic finding the neck of gallbladder showed well differentiated papillary adenocarcinoma confined to superficial part of musele layer. 3 years before admission she took T-tube drainage due to obstructive jaundice. The microscopic finding af distal common bile duct showed well differentiated adenocarcinoma. Recently she complained of pain and discomfort on T-tube site and so we perforrned endoscopic retrograde biliary drainage after removal of T-tube. The computed tomogram showed no mass in liver or lymph node enlargement. 4 months after procedure of ERBD; we changed to the new catheter for the prevention of cloggiag of prosthesis. We report here a case of longterm survival over 15 years after the diagnosis of cancer of extrahepatic bile duct.
