Intravascular (IV) catheter sepsis is a widely recognized complication of IV therapy or monitoring, but little emphasis has been placed on the morbidity and cost associated with this infection. To assess the consequences of IV catheter sepsis, we examined the medical records of 94 patients with 102 episodes of IV catheter sepsis due to percutaneously inserted catheters. Major complications occurred in 33 (32%) of the episodes and included septic shock (12 episodes), sustained sepsis (12), suppurative thrombophlebitis (7), metastatic infection (5), endocarditis (2), and arteritis (2). ⋯ The hospital cost of IV catheter sepsis was assessed by reviewing medical and billing records to identify extra medical care and then multiplying charges for that care by the appropriate cost-to-charge ratio. The average cost per episode, adjusted to 1991 dollars, was $3,707 for all episodes and $6,064 for episodes caused by S. aureus. The morbidity and cost associated with IV catheter sepsis warrant substantial efforts to minimize the incidence of this complication and especially to prevent cases due to S. aureus.

Review Case Reports
Bacteremia due to Pseudomonas aeruginosa in children with AIDS.
Six episodes of Pseudomonas aeruginosa bacteremia in five children with AIDS were reviewed to characterize further the disease caused by this pathogen. Hypotension occurred in five episodes, and two children died. ⋯ None of the children had catheter-associated infection, and only three were neutropenic. P. aeruginosa should be considered as a cause of sepsis in children with AIDS.

Case Reports
Inhibition of the scarlet fever exanthem in concurrent varicella and group A streptococcus infection.
An atypical scarlet fever exanthem was noted in a 5-year-old child with varicella complicated by secondary group A beta-hemolytic streptococcus pneumonia and empyema. The rash consisted of symmetrical, concentric, circular exanthem-free zones surrounding individual varicella vesicles. The possible role of virus-induced interferon in locally modifying the effect of streptococcal pyrogenic exotoxin is explored.

Review Case Reports
Menstrual toxic shock syndrome complicated by persistent bacteremia: case report and review.
An unusual case of menstrual toxic shock syndrome (TSS) is described in which the patient had persistent Staphylococcus aureus bacteremia despite therapy with iv cloxacillin. There was no demonstrable evidence of endocarditis or an abscess as a focus for persisting bacteremia. The strain of S. aureus isolated from the blood and vagina produced toxic shock syndrome toxin 1 (TSST-1) and enterotoxin A. Bacteremia occurs uncommonly in association with TSS; however, aggressive high-dose antistaphylococcal therapy should be instituted for treating this possible complication.

Comparative Study
Epidemiology of infections with Pseudomonas aeruginosa in burn patients: the role of hydrotherapy.
Pseudomonas aeruginosa remains a cause of serious wound infection and mortality in burn patients. By means of restriction fragment length polymorphism analysis and a DNA probe for the pilin gene of Pseudomonas, a lethal strain of nosocomial P. aeruginosa was identified as the cause of an outbreak of wound infections among burn patients. ⋯ In a trial of burn wound care without hydrotherapy, overall mortality was reduced significantly, mortality associated with pseudomonas sepsis was eliminated, and the strain of P. aeruginosa associated with earlier mortality was eradicated. Moreover, fewer nosocomial pseudomonas infections, lower levels of pseudomonas resistance to aminoglycoside antibiotics, significantly fewer pseudomonas infections of skin graft donor sites, and later appearance of Pseodomonas species in burn patients were found during the period when hydrotherapy was not used.
