ABSTRACT: To determine the frequency and effects of nosocomial respiratory viral infections (RVIs) in premature neonates, including those who may be asymptomatic.
We performed a year-long surveillance for RVIs in infants <33 weeks gestational age admitted to 2 Syracuse neonatal intensive care units. Infants were enrolled within 3 days of neonatal intensive care unit admission and were sampled for RVIs until discharge using a multiplex polymerase chain reaction assay capable of detecting 17 different respiratory viruses or subtypes.
Twenty-six of 50 prematurely born infants (52%) tested positive for a respiratory virus at least once during their birth hospitalization. Testing positive for a respiratory virus was significantly associated with longer length of stay (70 days vs 35 days, P = .002) and prolonged ventilatory support (51 vs 13 days, P = .002). Infants who tested positive for a respiratory virus during their birth hospitalization had more than twice the rate of developing bronchopulmonary dysplasia (P < .05).
Nosocomial RVIs were frequent in our study population, despite the absence of clinical indicators of illness. Length of hospital stay was significantly longer and a diagnosis of bronchopulmonary dysplasia was more common in infants who had respiratory viruses detected.

ABSTRACT: An infant had a subdural empyema caused by the rare Salmonella species enterica subspecies houtenae (IV) serotype 44:z4,z23:- after only indirect exposure to exotic reptiles in her foster home. Infants recovering from preexisting subdural hematoma are at risk for development of empyema.

ABSTRACT: Laryngoscope blades are often cleaned between cases according to well-defined protocols. However, despite evidence that laryngoscope handles could be a source of nosocomial infection, neither our institution nor the American Society of Anesthesiologists has any specific guidelines for handle disinfection. We hypothesized that laryngoscope handles may be sufficiently contaminated with bacteria and viruses to justify the implementation of new handle-cleaning protocols.
Sixty laryngoscope handles from the adult operating rooms were sampled with premoistened sterile swabs. Collection was performed between cases, in operating rooms hosting a broad variety of subspecialty procedures, after the room and equipment had been thoroughly cleaned for the subsequent case. Samples from 40 handles were sent for aerobic bacterial culture, and antimicrobial susceptibility testing was performed for significant isolates. Samples from 20 handles were examined for viral contamination using a polymerase chain reaction assay that detects 17 respiratory viruses.
Of the 40 samples sent for culture, 30 (75%) were positive for bacterial contamination. Of these positive cultures, 25 (62.5%) yielded coagulase-negative staphylococci, seven (17.5%) Bacillusspp. not anthracis, three (7.5%) alpha-hemolytic Streptococcusspp., and one each (2.5%) of Enterococcusspp., Staphylococcus aureus(S. aureus), and Corynebacteriumspp. No vancomycin-resistant enterococci, methicillin-resistant S. aureus, or Gram-negative rods were detected. All viral tests were negative.
We found a high incidence of bacterial contamination of laryngoscope handles despite low-level disinfection. However, no vancomycin-resistant enterococci, methicillin-resistant S. aureus, Gram-negative rods, or respiratory viruses were detected. Our results support adoption of guidelines that include, at a minimum, mandatory low-level disinfection of laryngoscope handles after each patient use.

ABSTRACT: We report a case of a previously healthy 38-year-old male with acute prostatitis and concurrent Pseudomonas aeruginosa urosepsis. Pulsed-field gel electrophoresis analysis confirmed that the source of the organism was the patient's newly purchased hot tub, which was filled with water from a stream.

ABSTRACT: Pinworm infection is a very common diagnosis in young children that is not always confirmed through laboratory evaluation before empiric therapy is prescribed. This article describes a toddler who was treated several times for pinworms because small white worms were seen in her perianal area. Laboratory analysis of parasite material found in her diaper later confirmed a diagnosis of dipylidiasis. Because the signs of dipylidiasis and pinworm infection overlap and the treatments for these parasitic infections are different, the laboratory should clinically confirm suspected persistent or recurrent pinworms.
