Severe community-acquired pneumonia (CAP) is usually defined as pneumonia that requires intensive care unit (ICU) admission; the primary pathogen responsible for ICU admission is Streptococcus pneumoniae. In this study, the 2007 Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) consensus criteria for ICU admission were compared with other severity scores in predicting ICU admission and mortality. ⋯ This study confirms the usefulness of the new criteria in predicting severe CAP. The 2001 ATS criteria seem an attractive alternative because they are simple and as effective as the 2007 IDSA/ATS criteria.

Necrotizing fasciitis is a severe life-threatening soft tissue infection characterized by rapidly spreading necrosis of the fascia and the subcutaneous tissue. Mortality as a result of streptococcal necrotizing fasciitis has been associated with the presence of hypotension, streptococcal toxic shock syndrome, or bacteremia in the literature. These infections are rare in children, and the diagnosis should be considered in the presence of any soft tissue infection presenting with signs of toxicity and marked wound edema. ⋯ A high index of suspicion is most important when there is a paucity of specific cutaneous findings early in the course of the disease. The diagnosis of necrotizing fasciitis should be considered for any individual who has unexplained limb pain. Even for treating patients with minor trauma, the emergency department physician should keep a high level of suspicion of the possibility of a fatal outcome from the subsequent invasive streptococcal infection.

Comparative Study
The role of continuous positive airway pressure in acute cardiogenic edema with preserved left ventricular systolic function.
The objective of the study was to compare the effect of continuous positive airway pressure (CPAP) in patients with acute cardiogenic pulmonary edema (ACPE) with preserved or impaired left ventricular systolic function with regard to resolution time. ⋯ The results of this preliminary study show that resolution time is not significantly different in patients with ACPE with preserved or impaired systolic function submitted to CPAP.

Delayed seizures have been reported with overdoses of bupropion extended-release (XL). This study systematically evaluates the frequency and timing of seizures and an association between other toxic effects (ie, agitation, tremors, and hallucinations) and seizures. ⋯ Delayed seizure onset suggests a minimum observation period of 24 hours after bupropion XL overdose. Although patients experiencing agitation or tremors may be at greater risk, seizures can occur without preceding central nervous system toxicity.

Prolonged endotracheal tube cuff pressures (ETTCPs) greater than 30 cm H(2)O cause complications ranging from sore throat to rare cases of tracheoesophageal fistula. In a series of patients, we sought to determine the proportion of patients with overinflated cuffs and to determine whether overinflation was associated with demographics, diagnostic category, or intubator credentials. ⋯ The most compelling results of the study are the high rates of elevated ETTCPs. Furthermore, there were no clear risk factors for elevated ETTCP. Although the risk of elevated ETTCP in the prehospital to acute care time frame is unclear, it seems reasonable to measure ETTCP after intubation in all patients.
