    In this manuscript we are presenting the first National Epidermolysis Bullosa Epidemiology study done in South America. Our manuscript describes not only population-level estimates, such as incidence, prevalence and mortality of EB, but also genetic data that are unique to this underrepresented population. We report new data about this rare disease showing comparable life expectancy to wealthier nations, demonstrating the value of specialized EB care centres.

    Evaluación de la sensibilidad diagnóstica de tres técnicas de laboratorio para la infección por influenza A: inmunocromatografía, IFD e IFD con citocentrifugado versus RPC-TR

    Introduction: The specific diagnosis of influenza A infection makes. it possible to control its spread, decreases the unnecessary use of antibiotics, clinical procedures and laboratory test, and allows early recognition of outbreaks. Different technologies are currently available in Chile for this purpose. Objective: The study presented here compares the sensitivity for influenza A virus detection of immunocromatography (RIDT), direct fluorescent antibodies-DFA and DFA with cytocentrifugation against the gold standard, RT-PCR. Material and Methods: In 175 nasal swab samples influenza, RIDT and RT-PCR were performed. Another 1689 nasal swab samples were tested by DFA and RT-PCR for influenza A. Finally, 29 nasal swab samples confirmed as Influenza A positive by RT-PCR welt tested by DFA with cytocentrifugation. Results: The RIDT, DFA and DFA + cytocentrifugation sensitivity was 47,3%, 57,2% and 72,4%, respectively. Discussion and Conclusion: Their lower cost and faster turnaround time when compared to PCR make RIDT and DFA the tests of choice in diagnostic laboratories in Chile. However, their low sensitivity and NPV, especially during low season, makes more sensitive diagnostic tools necessary to confirm the results. In our study cytocentrifugation increased DFA sensitivity from 57% to 72%.
