Bacteremia detected by lysis direct plating in a neonatal intensive care unit.
The density of bacteremia was determined in 787 neonatal blood specimens by using the 1.5-ml Isolator microbial tube. Coagulase-negative staphylococci were the organisms isolated most frequently from both true-positive cultures (25 of 50) and contaminated cultures (57 of 131). ⋯ Indwelling intravascular lines were associated with the majority of the episodes of sepsis. The distribution of pathogens causing sepsis in this neonatal population was similar to the distribution of microorganisms associated with cannula-related sepsis in other hospitalized patients.

Reliability of right atrial pressure monitoring to assess left ventricular preload in critically ill septic patients.
Right atrial pressure (RAP) can be used as a guide to fluid therapy in critical care settings. RAP and pulmonary capillary wedge pressure (WP) were measured in 27 septic patients without cardiac disease and on mechanical ventilation. ⋯ The reliability of various RAP interval values in predicting optimal WP was then studied in these patients. We concluded that RAP values less than or equal to 5 mm Hg were highly specific (97%) in predicting low or normal WP (less than or equal to 12 mm Hg).

Septic thrombophlebitis of the jugular vein (Lemierre's syndrome) is a severe complication of oropharyngeal infections. The extension of the infection to the cardiovascular system favors its dissemination to the lung and, eventually, to other points in the organism. We report two cases of Lemierre's syndrome seen in a 10-year period. The diagnostic and therapeutic aspects are particularly emphasized so as to stimulate the knowledge of this uncommon condition.
