OBJECTIVE The objective of this study was to describe the auditory evoked response to silent gaps for a group of older adults using stimulus conditions identical to those used in psychophysical studies of gap detection. DESIGN The P1-N1-P2 response to the onsets of stimuli (markers) defining a silent gap for within-channel (spectrally identical markers)(More)
BACKGROUND To evaluate the diagnostic value of Gram stain of pericatheter skin swabs and the intravascular device hub in detecting catheter-related bacteremia (CRB) in critically-ill patients. METHODS Over a 12-month period, 170 intravascular catheters (> 7 days in place) suspected as being the primary source of CRB were prospectively examined in adult(More)
A study was designed to compare an avidity index method to the serologic testing algorithm for recent human immunodeficiency virus (HIV) seroconversion (STARHS) for the detection of recent HIV infection. One hundred sixty HIV-positive sera were tested. Both techniques performed similarly in identifying recent infections, although STARHS tended to(More)
OBJECTIVE Atypical antipsychotic medications have generally been found to be more effective than conventional antipsychotics in the treatment of negative symptoms. Whether the benefits derived from the atypical agents are the result of improvements in primary versus secondary negative symptoms is unclear. The authors examined the effects of olanzapine on(More)
OBJECTIVES Clients of female sex workers (FSWs) are an important target group for human immunodeficiency virus/sexually transmitted infection (HIV/STI) prevention. This study aimed to estimate their HIV and other STI prevalence, examine their risk behaviors, and evaluate their role as a bridge population in the spread of HIV/STIs. METHODS A(More)
INTRODUCTION The objectives of this study were to estimate the prevalence of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) among injection drug users (IDUs) and identify the sociodemographic and behavioral factors in this population associated with these infections. METHODS Cross-sectional study in IDUs recruited in Catalonia in 2006. (More)
Hepatitis C virus (HCV) infection represents a major public health issue. Hepatitis C can be cured by therapy, but many infected individuals are unaware of their status. Effective HCV screening, fast diagnosis and characterization, and hepatic fibrosis staging are highly relevant for controlling transmission, treating infected patients and, consequently,(More)
OBJECTIVES The objectives of this study were to assess the prevalence of transmitted HIV-1 drug resistances (TDR) and HIV-1 subtypes in recently infected patients in Catalonia between 2003 and 2005 and to describe the characteristics of these patients according to the presence or absence of TDR and HIV-1 subtype. METHODS After application of the(More)
We report on a 15-year-old patient who was diagnosed with congenital myasthenic syndrome (CMS) at the age of 7 months. At initial diagnosis, the CMS was not further characterized. The patient was treated for several years with the anticholinesterase drug (Mestinon), without clinical benefit. The patient deteriorated progressively and became dependent on(More)
A newborn baby with complex congenital heart disease had severe persistent pericardial effusion after a systemic-pulmonary shunt. Pericardiocentesis and pericardiotomy could not stop pericardial leakage. At reoperation, topical application of a fibrin glue resulted in resolution of the leak and avoided replacement of the graft.
