Case ReportsPseudomonas cross-infection from cystic fibrosis patients to non-cystic fibrosis patients: implications for inpatient care of respiratory patients.
A 14-year-old boy with bronchiectasis secondary to chronic aspiration developed multiresistant Pseudomonas aeruginosa lower respiratory disease following several inpatient periods where accommodation and physiotherapy services were shared with cystic fibrosis (CF) patients known to be infected with the genetically identical strain of P. aeruginosa. Cross-infection with P. aeruginosa between CF patients and non-CF patients has not previously been described, and this finding raises significant issues relevant to the treatment of patients with non-CF suppurative lung disease.

Improved outcomes associated with limiting identification of Candida spp. in respiratory secretions.
Pneumonia due to infection with Candida spp. is extremely rare even though these yeasts are commonly cultured from respiratory secretions. The diagnosis of pneumonia due to Candida spp. should be made only by demonstrating tissue invasion of a biopsy specimen. Physicians might misinterpret the presence of Candida spp. in respiratory secretions as being the etiological agent of pneumonia. ⋯ Limited ID patients had a mortality rate of 14.3%; that of full ID patients was 18.7%, a decrease of 4.4% (P = 0.37). This policy of limiting yeast ID did not impair the diagnosis of pneumonia. Rather, decreases in lengths of stay, costs, and administration of unnecessary antifungal therapy were observed after instituting this policy.
