RESUMO
The purpose of this study is to evaluate the effects of occlusive wet dressing by using hydrophilic polyurethane foam (Medifoam ) in the management of donor sites of split thickness skin graft. The outer layer of Medifoam is made of a polyurethane film, which is impermeable to water and microorganisms. It provides moist wound environment and effective bacterial barrier. The middle layer is polyurethane foam, the absorption layer. Its swelling ratio is 1020% and the layer contains wound promoters (Glycosamnioglycan, etc.). The inner layer is polyurethane film, which has micro pores whose size is below 20mum. It prevents epithelial ingrowth into the pore. We performed half side test to compare Medifoam to AHD (the hydrocellular dressing materials). We divided STSG donor site into AHD dressing site and Medifoam dressing site in random fashion. This study was performed in Seoul National University Hospital from April 2001 till August 2001 with 32 patients, who needed to skin graft. We investigated about pain, comfort, easiness of handling, and time for complete healing. The Medifoam dressed site had less pain, more comfortable, easier handling and more rapid wound healing. The average healing time of Medifoam is 9.4 +/- 1.9 days and AHD is 12.6 +/- 1.9 days(p< 0.001). So we concluded that the occlusive dressing with Medifoam is an effective dressing method in split thickness skin graft donor site. And we expect that it is also effective dressing material in many other wounds.

BACKGROUND: Annual occurrence of vivax malaria in Republic of Korea (ROK) has exceeded 1,000 cases since 1997. Military system is thought to be a important source of the current outbreak. We collected the information on malaria cases of ROK army, veterans and civilians which occurred in 1999, and analyzed the characteristics of the current outbreak. METHODS: Informations on malaria cases of ROK army, including name, age, sex, rank, force, day of onset, region, etc., were collected through the Office of Surgeon General at Headquarters of ROK army and then analyzed. Informations about malaria cases of veterans and civilians, including age, sex, day of onset, region, etc., were collected through the National Institute of Health and then analyzed. RESULTS:Among a total of 3,628 cases in 1999, 1,085 (29.91%) occurred in the military, 996 (27.45%) occurred in veterans, and 1,547 (42.64%) occurred in civilians. Monthly occurrence reached its peak level at July and had maintained to August. Yeoncheon, Cheolwon and Paju were the highest prevalence region. CONCLUSION: Case occurrence in ROK decreased in 1999 and it was contributed by chemoprophylaxis which has been done since 1997 in the military. It is thought that more attention must be given to protect the further spread of malaria infection.
