Although studies have assessed short-term mortality among patients with community-acquired pneumonia, there is limited data on prognosis and risk factors that affect long-term mortality. The mortality among patients enrolled at 4 sites of the Pneumonia Patient Outcome Research Team cohort study who survived at least 90 days after presentation to the hospital was compared with that among age-matched control subjects. ⋯ Factors significantly associated with long-term mortality were age (stratified by decade), do-not-resuscitate status, poor nutritional status, pleural effusion, glucocorticoid use, nursing home residence, high school graduation level or less, male sex, preexisting comorbid illnesses, and the lack of feverishness. This study demonstrates that there is significantly higher long-term mortality among patients with pneumonia than among age-matched controls and that long-term mortality largely is not affected by acute physiologic derangements.

Previous studies of infected human bites have been limited by small numbers of patients and suboptimal microbiologic methodology. We conducted a multicenter prospective study of 50 patients with infected human bites. Seventy percent of the patients and assailants were young adult men. ⋯ Fusobacterium, Peptostreptococcus, and Candida species were isolated more frequently from occlusional bites than from clenched-fist injuries. Many strains of Prevotella and S. aureus were beta-lactamase producers. Amoxicillin-clavulanic acid and moxifloxacin demonstrated excellent in vitro activity against common isolates.

Eighteen adult patients with serologically confirmed West Nile virus (WNV)-associated meningitis or meningoencephalitis were admitted to our hospital during the 2000 West Nile fever outbreak in Israel. Thirteen of the patients had a more severe and prolonged clinical course, and an electroencephalogram (EEG) was, therefore, requested. ⋯ Two patients had normal EEG findings. We suggest that WNV meningoencephalitis should be considered in the differential diagnosis of meningitis or meningoencephalitis with a prolonged clinical course and anteriorly predominant slowing on an EEG.
