BACKGROUNDS: This study was performed to determine the onset time and dose of intranasal midazolam used for preanesthetic sedation in children. METHODS: The children were randomly allocated to recieve one of three medications via the nasal route in a double blind manner. Group I: patients were given normal saline 0.2 ml/5kg, Group II: patients were given midazolam 0.2 mg/kg, Group III: patients were given midazolam 0.3 mg/kg. RESULTS: The cardiovascular and SpO2 changes were not significantly different among the patients of the three groups. The sedation score was greater in group II compared with group I from 5 minute after administration (1.9 vs 2.7, p<0.05). postanesthetic recovery score (PARS) was not significantly different among the three groups. CONCLUSIONS: It is suggested that intranasal midazolam (0.2 mg/kg) produces anxiolysis and sedation in children with rapid onset.

PURPOSE: This study was undertaken to investigate whether expression of angiogenic cytokines including IL-8 and MCP-1 is induced in the cultured RPE by oxidative stress. METHODS: ARPE-19 cells were exposed to H2O2 and paraquat for 24, 48, and 72 hours and then assayed for the detection of IL-8 and monocyte chemotactic protein (MCP)-1 expression by reverse transcriptase polymerase chain reaction (RT-PCR) method. To determine whether the antioxidant overcame the oxidative stress, we observed expression of IL-8 and MCP-1 gene after ARPE cells were treated by paraquat and antioxidants including N-acetylcysteine (NAC) and pyrrolidine dithiocarbamate (PDTC) at the same time for 72hr. RESULTS: Expressions of the angiogenic cytokines, IL-8 and MCP-1 were increased by incubating with paraquat for 72hr. Antioxidants including NAC and PDTC decreased the expression of IL-8 and MCP-1 gene by counteracting the paraquat effect. CONCLUSIONS: Oxidative stress stimulates angiogenic cytokines including IL-8 and MCP-1 in the cultured RPE. These results may be significant for understanding the cause of age-related macular degeneration and its treatment.

PURPOSE: To obtain the findings of normal variant types of lower cervical body configuration for the purpose of differention from compression fracture. MATERIALS AND METHODS: We retrospectively analysed simple true lateral radiographs of cervical spine from C3 to C7 in 157 pediatric patients who did not have definitive clinical symptoms of cervical spinal injury. We classified the variations of normal cervical spine into 5 types by their configuration. In case of rounded upper corner or anteriorly wedged type, we measured the height and the width of vertebral body to classify these types, and undertook ANOVA test and multiple range test to determine the correlation between the gross configuration and the measured values. RESULTS: Type 1 was similarly observed at each of C3 to C7 in age of 1-4 group but the frequency was markedly decreased in age of 5-8 group. Type 2a was frequently observed at both age groups, and its incidence increased considerally at C3 and C4 with advancing age. Type 2b was more frequently observed at C3 body and Type 3 was observed only at C3 body in age group 1-4. Type 4 was markedly increased at 5-8 age group. Type 2b and 3 were seen mostly at C3, but sometimes at C4 body. Height of body was statistically more significant than width of body in classification of type 2a, 2b and 3. CONCLUSION: The configuration of lower cervical spine in infants and children changes from immature oval type(type 1) to mature rectagular type(type 4) with increasing age. Among the 4 types, the rounded upper corner type or anterior wedging type of lower cervical spine should be differentiated from compresson fracture. We concluded that the height of cervical body is more significant than the width of body in simple radiographic classification of types 2a, 2b and 3.
