A 33-years-old man was admitted to the intensive care unit because of alcoholic cirrhosis, cocaine toxicity, and septic shock to be accurately assessed. Further tests were requested. His X-ray did not show compatible patterns with pulmonary strongyloidiasis, blood culture was positive for enterobacteria that produce Klebsiella pneumoniae carbapenemase (KPC), and discrete eosinophylin hemogram and tracheal secretion culture were observed. […]

ABSTRACT Objective To describe the microbiological characteristics and to assess the risk factors for mortality of ventilator-associated tracheobronchitis in a case-control study of intensive care patients. Methods This case-control study was conducted over a 6-year period in a 40-bed medical-surgical intensive care unit in a tertiary care, private hospital in São Paulo, Brazil. Case patients were identified using the Nosocomial Infection Control Committee database. For the analysis of risk factors, matched control subjects were selected from the same institution at […]

DOI: 10.1590/S1679-45082017AO3936

ABSTRACT Objective To investigate whether the urine dipstick screening test can be used to predict urine culture results. Methods A retrospective study conducted between January and December 2014 based on data from 8,587 patients with a medical order for urine dipstick test, urine sediment analysis and urine culture. Sensitivity, specificity, positive and negative predictive values were determined and ROC curve analysis was performed. Results The percentage of positive cultures was 17.5%. Nitrite had 28% sensitivity and 99% specificity, with positive […]

ObjectiveTo test and validate a multiplex real-time polymerase chain reaction method for bloodstream infections, as well as to compare the results with conventional blood culture.MethodsA total of 114 consecutive patients with clinical evidence of sepsis were submitted to blood culture and LightCycler™ SeptiFast tests.ResultsMore positive specimens (23; 20.2%) were detected using the LightCycler™ SeptiFast than the blood culture (17; 14.9%), with an agreement of 86.8%. Discordant results were seen in four patients positive only to blood culture, ten positive only […]

Lais Pinto de Almeida, Fabiana Puerro de Carvalho, Alexandre Gimenes Marques, Andrea dos Santos Pereira, Renata Puzzo Bortoleto, Marinês Dalla Valle Martino

DOI: 10.1590/S1679-45082012000400008

Objective:To evaluate ertapenem disk performance to predict Klebsiella pneumonie carbapenemase production by Gram-negative bacilli.METHODS:All Gram-negative bacilli isolated between January 2010 and June 2011 were tested by disk diffusion (OxoidTM) for sensitivity to ertapenem, meropenem and imipenem. Resistant or intermediate sensitivity strains (diameter
