The combination of HSV1 and a host factor, the type 4 allele of the gene for(More)
BACKGROUND Health care workers (HCWs) are a group at risk of latent tuberculosis infection (LTBI). The aims of this study were to determine IFN-gamma response by QuantiFERON-TB GOLD In Tube (QFN-G-IT) and T-SPOT.TB in HCWs, comparing the results with tuberculin skin test (TST); and to analyze the capacity of IFN-gamma tests to detect recent versus remote(More)
The aim of our work here was to evaluate the immunogenicity of 60 mycobacterial antigens, some of which have not been previously assessed, notably a novel series of in vivo-expressed Mycobacterium tuberculosis (IVE-TB) antigens. We enrolled 505 subjects and separated them in individuals with and without latent tuberculosis infection (LTBI) vs. patients with(More)

We evaluated the impact of the copper-silver ionization system in a hospital where hyperendemic nosocomial legionellosis and was present and all previous disinfection measures had failed. After implementation of the copper-silver ionization system, environmental colonization with Legionella species decreased significantly, and the incidence of nosocomial(More)
INTRODUCTION The obstructive sleep apnoea syndrome (OSAS) is characterized by destructured sleep due to repeated episodes of obstruction of the superior respiratory tract during sleep. Treatment by nasal continuous positive airway pressure (n-CPAP) using air is one of the most common forms of treatment of OSAS, although some patients cannot tolerate it. One(More)
The results obtained in the laboratory diagnosis of 609 cases of acute or subacute encephalitis, studied during a period of time of even years, is briefly presented. Diagnostic methods included virus isolation from stools and cerebrospinal fluid (CSF); specific serology in serum; detection of intrathecal production of IgG antibody; and, in the last two(More)
