Objective: Measure time required to determine total body surface area (TBSA) burned (%TBSA) using the Lund-Browder chart and BurnCase 3D®, and calculate discrepancy between the two methods' %TBSA estimates.Methods: We asked 3 burn experts with 7 to 9 years of experience to participate in our experiment by estimating TBSA burned (%TBSA) for 26 subjects with a total of 262 photos, based on the Lund-Browder chart and the BurnCase 3D. We also measured time required for each estimation. Results: Estimations via the Lund-Browder chart and the BurnCase 3D showed statistically significant differences for Observers 1 and 2 (p < 0.05), but not for Observer 3 (p = 0.11). Inter-observer variability was insignificant among the observers (p = 0.31). When using the BurnCase 3D, burn estimation was consistent across the 3 participants (p = 0.31), yet the time spent for each method was significantly different (p < 0.05) from using the Lund-Browder chart and the time spent for estimation did not statistically vary (p = 0.20). Time spent on burn estimation varied when using either the Lund-Browder chart or the BurnCase 3D for all participants (p < 0.05). Conclusion: Using the BurnCase 3D over the Lund-Browder chart produced slightly different estimations for TBSA burned but estimation results stayed stable across inspectors. Due to the small sample size however, further investigation is necessary.

Hepatitis D is transmitted by the parenteral route. Those afflicted are individuals who have been infected with Hepatitis B virus as the Hepatitis D (HDV) virus needs the HBsAg (hepatitis B surface antigen) to replicate. The disease is present worldwide, but control of the hepatitis B virus (HBV) in the last decades has consistently diminished the circulation of HDV in industrialized countries; in these countries, the infection remains a medical issue for injection drug users as well as immigrants from endemic HDV areas. Infection with HDV is a major medical scourge in low income regions of the globe in which the HBV remains endemic.
