An epidemiological link between respiratory infection and acute myocardial infarction (AMI) has been suggested, and recent data indicate that there is an association between AMI and pneumococcal community-acquired pneumonia (CAP) in hospitalized patients. The objective of this study was to investigate the association of AMI with the severity of pneumonia at hospitalization and clinical failure during hospitalization among patients with CAP. ⋯ A combined diagnosis of CAP and AMI is common among hospitalized patients with severe CAP. In cases in which the clinical course of a hospitalized patient with CAP is complicated by clinical failure, AMI should be considered as a possible etiology.

Randomized Controlled Trial
High-dose amphotericin B with flucytosine for the treatment of cryptococcal meningitis in HIV-infected patients: a randomized trial.
The standard therapy for human immunodeficiency virus (HIV)-associated cryptococcal meningitis of amphotericin B (AmB; 0.7 mg/kg per day) plus flucytosine frequently takes >2 weeks to sterilize the cerebral spinal fluid, and acute mortality remains high. A dosage range for AmB of 0.7-1 mg/kg per day is noted in current guidelines, but there are no data comparing 0.7 mg/kg per day with 1 mg/kg per day. ⋯ ISRCTN68133435 (http://www.controlled-trials.com).

Long-term care facilities (LTCFs) are vulnerable to outbreaks of influenza. There are limited data on the impact of antiviral chemoprophylaxis on the duration of outbreaks of influenza. We investigated the association of timely initiation of amantadine chemoprophylaxis on the duration and severity of outbreaks of influenza A in LTCFs in New York, New York. ⋯ LTCFs that initiated chemoprophylaxis >5 days after initiation of outbreaks of influenza A had significantly longer outbreaks, significantly higher incidence rates, and significantly higher case-fatality rates. These data support prompt initiation of amantadine chemoprophylaxis after identification of influenza A in LTCFs.

Infection control personnel are required to develop institutional guidelines for prevention of transmission of multidrug-resistant organisms, especially methicillin-resistant Staphylococcus aureus, within health care settings. Such guidelines include performance of active surveillance cultures for patients after admission to health care facilities or to high-risk-patient care units, to detect colonization with target multidrug-resistant organisms. ⋯ Relevant infection control, public health, and ethical principles are reviewed in an effort to provide guidance for ethical decision making when designing a multidrug-resistant organism control program that includes active surveillance cultures and contact precautions. We conclude that a program of active surveillance cultures and contact precautions is part of standard medical care that requires patient education but not a specific informed consent and that the cost for such programs should be assigned to the health care institution, not the individual patient.

Data on infections associated with cerebrospinal fluid (CSF) shunts among adults are limited. Therefore, we performed a retrospective study of shunt-associated infections in adults. ⋯ Shunt-associated infections among adults often present with nonspecific clinical signs, and affected patients can have normal CSF leukocyte counts and lactate levels; therefore, a high index of suspicion and improved methods are required for diagnosing shunt-associated infection.
