Pneumonia was a common complication among hospitalized patients with 2009 pandemic influenza A H1N1 [pH1N1] in the United States in 2009. ⋯ Hospitalized patients with pH1N1 and pneumonia were at risk for severe outcomes including ARDS, sepsis, and death; antiviral treatment was often delayed. In the absence of accurate pneumonia diagnostics, patients hospitalized with suspected influenza and lung infiltrates on chest radiography should receive early and aggressive treatment with antibiotics and influenza antiviral agents.

Tuberculosis contact investigation identifies individuals who may be recently infected with tuberculosis and are thus at increased risk for disease. Contacts with latent tuberculosis infection (LTBI) are offered chemoprophylaxis to prevent active disease; however, the effectiveness of this intervention is unclear as treatment completion is generally low. ⋯ Contact investigation facilitates active case finding and tuberculosis prevention, even when completion rates of chemoprophylaxis are suboptimal.

Transrectal ultrasound-guided (TRUS) prostate biopsy is a commonly performed procedure, and fluoroquinolones are the most frequently given prophylactic antimicrobials. In the context of increasing fluoroquinolone resistance, and the international emergence of fluoroquinolone-resistant sequence type 131 (ST131) Escherichia coli, we describe a large series of E. coli bacteremia after TRUS biopsy. ⋯ E. coli bacteremia can be a life-threatening complication of TRUS biopsy. Infecting strains are frequently multidrug-resistant and resistant to common empirical antibiotic agents. E. coli ST131 is an important cause of sepsis after TRUS biopsy. Further studies should evaluate colonization with fluoroquinolone-resistant E. coli as a risk factor for postbiopsy sepsis.
