BACKGROUND: The implementation of intraoperative normovolemic hemodilution is a strategy used in an attempt to diminish the need for or obviate allogeneic transfusion and to avert the potential complications. The goal of this study was to evaluate the safety and efficacy of moderate intraoperative normovolemic hemodilution. METHODS: Fifteen patients scheduled for posterolateral spinal fusion underwent intraoperative normovolemic hemodilution with 10% pentastarch to a target hematocrit level of 25% (hemodilution group). All units of blood procured by hemodilution and additional allogeneic blood was transfused in the perioperative period to maintain the hematocrit level of>25%. We investigated the effect of hemodilution on whole blood coagulation as measured by the thromboelastography and, evaluated its efficacy of decreasing the need for allogeneic blood transfusion as compared to the nonhemodilution group, retrospectively. RESULTS: Hemodilution with pentastarch caused a decrease in response and coagulation time (p<0.01) but did not influence on the alpha angle and maximum amplitude on thromboelstogram. Amount of transfusion of allogeneic blood was 4.1 1.7 units for the hemodilution group and 5.0 1.5 units for the nonhemodilution group. Net red blood cell volume ""saved"" from hemodilution was about 120 ml. CONCLUSION: Moderate intraoperative normovolemic hemodilution with pentastarch does not affect the coagulability of whole blood. But its efficacy of decreasing the need for allogeneic blood transfusion is minimal.

It is thought that the sanitary perception and hygienic food treatment of food suppliers as the first handlers of foodstuffs are extremely significant for the safe and sanitary management of food in group meal services. So in this study, a survey of 103 food suppliers who provide raw materials for 80 meal services in business places around Buasn area was conducted on general matters, participation in sanitation education, sanitary perception, sanitary treatment of foodstuffs, knowledge of sanitation, etc. The results of the survey are as follows: 1. 42.7% of the subjects have worked for the food supply companies for one to five years and the main job of 36.9% of them is delivery service. Food suppliers who handle over two foodstuffs are 6839%. 2. Concerning the participation in sanitation education, 43.7% of the subjects have not experienced any such education, The reason of 23.3% of them for not having the education is that there have been no opportunity for them at all. And 83.5% of them regard the education on hygiene as necessary. 3. In the sanitary perception, 93.1% of the subjects considered the temperature control of the food delivery vehicles as important and 82.5% of them replied on of the leading causes of food poisoning as foodstuffs. 64.0% thought of their knowledge of food sanitation as not very good, but moderate. 4. Concerning sanitary treatment of foodstuffs, 50.5% of delivery vehicles were wearing sanitary uniforms and 24.3% of them washed their hands while supplying food. 5. In the score of hygienic knowledge, the average score of all food suppliers was 60.6 point. In the score of hygienic knowledge on general matters, managing supervisors got 6.31+/-1.81, meat suppliers scored 7.08+/-1.37 and suppliers with 5 to 10 year careers recorded the highest point, 6.37+/-1.70. In the score of hygienic knowledge based on the perception of food sanitation, the food suppliers with the experience of sanitation education scored 6.42+/-1.93 point and the point was significant(p<0.01), compared with that of the food suppliers without the experience of sanitation education. The food suppliers who answered their knowledge was very good scored the highest point, 8.00+/-1.41. The food suppliers who replied that sanitation education was truly necessary recorded the hygienic knowledge score of 6.75+/-1.77, significantly(p<0.01) high. In the score of hygienic knowledge on the basis of the practical degree of sanitary handling of food materials, the food suppliers who answered they cleaned their delivery vehicles everyday scored 6.48+/-1.93, the food suppliers who answered they sterilized their delivery vehicles everyday scored 6.29+/-1.89, the food suppliers who answered they controlled the themperature of their delivery vehicles irregularly scored 6.58+/-1.79 and the food suppliers who answered they washed their hands every time when they were working scored 6.86+/-2.24, significantly(p<0.05) high in comparison with every item in other factors. And the food suppliers who answered they were wearing sanitary uniforms irregularly while suplying foodstuffs scored the highest point, 6.66+/-2.92.

PURPOSE: To analyze the results of posterior capsule rupture (PCR) that occurred in the first 1000 cases performed by a newly trained phacoemulsification surgeon. METHODS: The medical records of 47 eyes of 45 patients who suffered PCR among the first 1000 cases of cataract surgery performed by one newly trained surgeon were reviewed. All surgeries started with the plan of phacoemulsification and there was no supervision by any experienced surgeon. RESULTS: Over the course of the series of 1000 cases, the PCR incidence rate steadily fell from 12% in the first 100 cases to 4.7% (47 cases) for all 1000 cases as the operator gained experience with the techniques. However, after the change of phaco machine and the technique of nucleus removal, the incidence increased abruptly to 11% and then decreased again. There was no significant difference in PCR incidence between surgeries of the first eye and the second eye of the 335 patients who underwent cataract surgery in both eyes by the surgeon (p=0.534). PCR occurred most commonly in the course of phacoemulsification (83.0%) and mainly in the eyes with severe nucleus sclerosis. CONCLUSIONS: In the early stages of the career of a phacoemulsification surgeon, the PCR incidence showed a learning curve that decreased with increasing experiences, then it increased again after the change of operational procedure before finally decreasing once more. In the surgery of the second eye, poor patient cooperation could be overcome with a careful approach, and PCR occurred most commonly in the course of phacoemulsification (83.0%).

The large outbreak of coronavirus disease 2019 (COVID-19) that started in Wuhan, China has now spread to many countries worldwide. Current epidemiologic knowledge suggests that relatively few cases are seen among children, which limits opportunities to address pediatric specific issues on infection control and the children's contribution to viral spread in the community. Here, we report the first pediatric case of COVID-19 in Korea. The 10-year-old girl was a close contact of her uncle and her mother who were confirmed to have COVID-19. In this report, we present mild clinical course of her pneumonia that did not require antiviral treatment and serial viral test results from multiple specimens. Lastly, we raise concerns on the optimal strategy of self-quarantine and patient care in a negative isolation room for children.
