Objective: Many trauma centers use their own criteria for major trauma patients, and these criteria are organized according to physiological causes and their related mechanisms. Mechanism related criteria have high sensitivity but low specificity. We confirmed 20 feet as a single factor for trauma team activation criteria. Methods: This study was retrospectively conducted in the Pusan National University Hospital trauma center, which is a level 1 trauma center in Busan. Patients were grouped as group 1, a fall from less than 20 feet; and group 2, a fall from more than 20 feet. We compare the two groups of prognostic factors using logistic regression analysis. Results: The relationship between the height of the fall and the patient’s prognosis showed a positive relationship on the logistic regression analysis. Yet the cut-off value of a 20 foot height showed poor predictive power for the patient’s prognosis. Conclusion In conclusion, as trauma team activation criteria, a 20 foot height seems to be a reasonable aspect of patients’ clinical prognosis between above 20 feet and below 20 feet. Yet it seems to be controversial as a cut-off value. Thus, more studies will be needed to identify a specific height for trauma team activation.

BACKGROUND: Porphyrins produced by Propionibacterium acnes exhibit an orange-red fluorescence spot on the pilosebaceous pore under UVA light. Based on this characteristic, the recently developed photographic technique, 'fluorescence photography', warrants mention in the context of acne, especially in the assessment of the presence of bacteria and sebum output. OBJECTIVE: The aim of this study was to assess the relationship between sebum output and acne lesion counts with fluorescent density (% fluorescence area). We discuss the possibility of the use of fluorescence photography as a new tool to evaluate acne and sebum levels. METHODS: Total of 39 subjects, 29 males and 10 females, were recruited for this prospective study. To estimate fluorescent density, fluorescent facial images were taken and analyzed with digital fluorescent imaging system and an image analysis program. The sebum output level was measured with a Sebumeter(R). Numbers of acne lesions were counted. Also, sebum output and fluorescent images were compared before and after the use of a facial cleanser containing 1% triclosan. RESULTS: Sebum output level was significantly associated with fluorescent density, but not with the number of acne lesions. However, in the group using triclosan containing cleanser, fluorescent density decreased, while sebum level increased. Therefore, fluorescent density seems to be influenced mainly by the density of P. acnes. CONCLUSION: Fluorescence density correlates with P. acnes mostly followed by sebum output level. Digital fluorescent imaging system is considered as a useful tool to assess sebum excretion as well as colonization of P. acnes.
