Burns is children result in the loss of precious life, or if the child survives, in much suffering from physical, emotional, social, and economic problems. These burn accidents to children happen in the bustle of family life and frequently without any warning. With this background information, this study was designed to identity types of burns in children and mother's attitudes towards, and knowledge of burn prevention, in order, to not only, in still a safety consciousness regarding the seriousness of burn accidents and the strengthening prevention, but also as basic data towards the development of an educational program aimed at prevention. From May 1 to May 25 in 1997, data were collected from the mothers of children attending five day care centers and kindergartens located in Seoul, which had been selected for the study. The tools used for the study, which were developed by the researchers, surveyed the type of burns suffered by children, mother's knowledge of burns and attitudes toward burn accidents. The data were analyzed through real numbers percentages and analysis was done using SPSS computer programs. The results of the study show that the most frequent type of burn accidents were those caused by hot water(55.4%) and these were frequently related to everyday habits that easily lead to danger. Further, the first aid treatment following a burn was weak. The majority of the mothers had not instructed their children on who to contact in the cape of a fire, first aid for burns, or how to take escape in the case of a fire. This left the children in a defenseless position in case of a fire. The mothers showed a lack knowledge, on what to do when a blaze is discovered, how to put out a fire, first aid for burns, escaping from a fire and appropriate water temperature, in that 50% of the time they answered incorrectly. From this study a prevention program, HIPP(Home Injury Prevention Program) could be developed that includes fire prevention habits and first aid for burns. This program can be used with kindergarten and elementary school children for group education fire prevention and can be used as a foundation for construction of a system of facilities and equipment to prevent fires and also prevent injury from fires.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

The use of CT is most reliable in diagnosis and management of brain abscess. Authors analized 17 cases of pathologically and clinically proven brain abscess during the period of 39 months from Jan. 1978 to Mar, 1982 at National Medical Center. The results were as follows; 1. The sex ration 9 males to 8 females, and no sexdifference was seen, and the greatest number of cases were seen below the age of 30(65%). 2. The otogenicinfection was the most frequent predisposing factors(8 cases). Other predisposing factors were postoperative infection (2 cases), pulmonary infection (2 cases), and congenital heart disease(2 cases). The most common site ofinvolvement was posterior fossa(5 cases). Next was temporal lobe (4 cases), and temporoparietal lobe (3 cases). 3.Most common presenting symptoms were headache, fever, focal neurological signs, and dizziness. 4. Among the 22 brain abscesses of 17 patients, the msot frequent CT finding in precontrast scan was a low density surrounded by afaint dense or dense ring (11 cases). Next was purely low density (6 cases). Associated hydrocephalus was found in4 cases, and multiple or multiloculated abscess was seen in 4 cases. 5. In post contrast scan, brain abscessusually show complete, oval or round shaped, thin, evening righ enhancement with mild or moderate surroundingedema, but there was no specific enhancement.

PURPOSE: We investigated the anti-inflammatory and anti-fibrotic effects of amniotic membrane(AM) ointment in filtering surgery of rabbits. METHODS: After filtering surgery was performed on both eyes of 10 rabbits, the AM ointment was applied over and under the scleral flap on one eye whereas base ointment excluding AM element was applied to the other as a control. The shapes of blebs were observed under slit-lamp biomicroscopy at postoperative 3 days, 1 week, 2 weeks and 4 weeks, and the tissues were excised for histologic studies. RESULTS: Serial changes of intraocular pressures had no significant difference. Slit-lamp biomicroscopy demonstrated that conjunctival blebs of AM ointment group were more elevated and cystic at 1 and 2 weeks. The heights of conjunctival blebs were significantly higher at 1, 2 and 4 weeks, and the width of scleral tracks was significantly wider at 1 and 2 weeks in AM ointment group. The number of inflammatory cells in the scleral track was significantly less at 3 days and 1 week, the number of fibroblasts in scleral track was significantly less at 2 and 3 weeks in AM ointment group. Masson s trichrome stain was less positive in AM ointment and the stain area of alpha-smooth muscle actin-positive fibroblasts was insignificant with image analysis system. Collagen type 3 appeared in scleral track from postoperative 1 week in control group, however, in AM ointment group, from 4 weeks. CONCLUSIONS: AM ointment is beneficial to suppress fibroblast differentiation, proliferation and inflam-matory reaction in filtering surgery and might be safe and effective adjunctive for enhancement of success in filtering surgery.

Arrhythmogenic right ventricular dysplasia is a rare heart muscle disorder of unknown cause that primarily involves the right ventricle. It is characterized pathologically by fibrofatty replacement of the right ventricular myocardium. Clinical manifestations include structural and functional abnormalities of the right ventricle, electrocardiographic depolarization/repolarization changes, and presentation with sudden death or ventricular arrhythmias of right ventricular origin. It is one of the important causes of the ventricular arrhythmia or sudden death among apparently healthy young people. We report a case of arrhythmogenic right ventricular dysplasia with the review of the literature.

We performed an in vitro study to determine the effects of ultra high molecular weight polyethylene (UHMWPE) particles on the cell proliferation, matrix synthesis(type I collagen mRNA), and cytokines production(interleukin-lbeta and prostaglandin E2) of MG63 osteoblastlike cells. UHMWPE wear particles were isolated from osteolysis tissue of 8 patients during revision hip arthroplasties. Sub-micron UHMWPE powders were also isolated from fabricated virgin UHMWPE powders. Group I (control culture) contained no UHMWPE particles. In group II andIII, the UHMWPE wear particles and the UHMWPE powders were added to cultures of MG63 osteoblastlike cells with the different concentration of 0.2mg/ml, 0.02mg/ml, 0.002mg/ml, and 0.0002mg/ml. The average diameter of the retrieved UHMWPE particles was 0.4micrometa(ranged, 0.1 to 1.4 micrometa), and that of the fabricated UHMWPE powders was 0.6micrometa(ranged, 0.1 to 2.3micrometa). In group II and III, the UHMWPE particles induced an increase in osteoblastlike cell growth(p<0.05) but they inhibited the expression of type I collagen mRNA in a dose dependent manner(p<0.05). MG63 osteoblastlike cells exhibited a dose-dependent release of interleukin-1beta(IL-1beta) and prostaglandin E2(PGE2) in response to the exposure to the UHMWPE particles(p<0.05). There were no differences in the cell proliferation, the expression of type I collagen mRNA, and the release of PGE2 between the UHMWPE wear particles and the UHMWPE powders groups(p>0.05). The release of IL-lbeta was higher in group II than in group III(p<0.05). These data support the hypothesis that direct suppression and cytokines release of MG63 osteoblastlike cells by UHMWPE particles may play a role in particle-mediated osteolysis.

Decerebrate rigidity, in which there is an exaggereted posture with continuous spasm of muscles, especially the extensors, was first produced in 1898 by Sherrington in animals by transection of the brain at a prepontine level. Since it was shown that intact vestibular nuclei were necessary for decerebrate ridigity to persist, the disorder was believed to be caused by release of vestibular nuclei from higher extrapyramidal control. We have experienced 42 cases of the presence of decerebrate ridigity following head injury who were admitted to the Chosun University Hospital from March 1972 to February 1976. Although no one doubts the prognostic gravity of the decerebrate state following cranial trauma, a surpring number of patients in this study survived in a reasonably functional state. The particular factors we have evaluated are the duration of decerebration, the presence or absence of an intracranial hematoma of surgical proportions, the time of surgical intervention in relation to onset of decerebration and the use of corticosteroids. 42 consecutive parients with traumatic decerebration were studied to determine factors that influence the recovery from the decerebrate state. All these cases were diagnosed by clinical findings and cerebral angiography and assessed the prognostic factors on the result of treatment. Although the data did not lend themselves to precise statistical analysis, it is our option that the following conclusions be inferred ; 1. Intracranial hematoma was found in 25 patients (about 60%) from 42 patients who were presence of decerebrate rigidity, among these the sites of intracranial hematoma were as follows ; a) Epidural hematoma was found in 8 patients(32%). b) Subdural hematoma was found in 13 patients(52%). c) Intracerebral hematoma was found in 4 patients(16%). 2. The mortality of decerebrate patients(65%) with direct damage to the brain stem was greater than that of those supratentorial hematoma(52%). However the quality of survival was better in the latter group, indicating the likehood that brain stem compression is often reversible after evacuation of the hematoma even though with residual neurological deflicit. 3. The mortality and morbidity were greater with traumatic intracerebral and subdural hematoma than with epidural hematoma. This correlation was probably related to the amount of associated diffuse brain damage. 4. A progressive increase in the mortality rate in the surgical group could be correlated with the duration of decerebrate rigidity prior to surgical intervention. 5. Patients who recovered from the decerebrate state usually survived even though with residual sequelae. 6. There was an increase in the mortality rate when decerebration persisted for more than on weeks, but there was one survivor after even 35 days of decerebrate state. 7. The mortality rate was highest over 40 years old and was on the contrary under 20 years old. 8. There was no specific effectiveness in the patients with the presence of decerebrate state with the use of parenteral corticosteroid therapy.
