Oral infection by Pseudomonas aeruginosa in patient with chronic kidney disease - a case report.

Chronic renal patients are more susceptible to hospital complications and infections such as urinary tract infections, peritonitis, surgery infections, and bacteremia, which are often caused by Pseudomonas aeruginosa. A case of a HIV-positive girl with chronic kidney disease and with serious oral lesions due to P. aeruginosa septic shock is presented.

Relationship between Periodontal Status and Ventilator-Associated Pneumonia.

Objective: This study tested the hypothesis that a relationship exists between periodontal disease status and ventilator-associated pneumonia (VAP) in patients admitted to an intensive care unit (ICU).

Materials And Methods: The periodontal status of 60 individuals admitted to the ICU of the Dutra University Hospital was determined, including measurement of visible plaque, gingival bleeding, and clinical attachment level. Data were analyzed by Chi-square or Fisher's exact tests, unpaired Student's t-test and multivariate logistic regression.

Association between pathogens from tracheal aspirate and oral biofilm of patients on mechanical ventilation.

The aim of this study was to detect possible associations between respiratory pathogens from tracheal aspirate and oral biofilm samples in intubated patients in an intensive care unit (ICU), and to identify the most common respiratory pathogens in oral biofilm, particularly in patients that developed ventilator-associated pneumonia (VAP). Two oral biofilm samples were collected from the tongue of intubated patients (at admission and after 48 hours) and analyzed by culture with the Antibiotic Sensitivity Test. The results from the tongue biofilm samples were compared with the tracheal secretions samples.
