Skin carriage of Acinetobacter calcoaceticus-baumannii complex was not detected among a representative sample of 102 US Army soldiers stationed in Iraq. This observation refutes the hypothesis that preinjury skin carriage serves as the reservoir for the Acinetobacter infections seen in US military combat casualties.
OBJECTIVE To describe the evolving epidemiology of fungal bloodstream infections in critically ill and noncritically ill patients and to identify predictors of infection with non-albicans yeast species. DESIGN Retrospective case series. SETTING Two academic, tertiary care centers. PARTICIPANTS All persons during a 4-yr period who developed fungemia.(More)
RATIONALE Investigators have postulated that mediastinal granulomatous inflammation is associated with prolonged overall survival in patients with cancer. OBJECTIVES We sought to determine whether mediastinal granulomatous inflammation affects overall survival in patients with a history of treated cancer. METHODS Patients with a history of treated(More)
RATIONALE Data about the influence of the type of sedation on yield, complications, and tolerance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are based mostly on retrospective studies and are largely inconsistent. OBJECTIVES To determine whether the type of sedation influences the diagnostic yield of EBUS-TBNA, its(More)
BACKGROUND Malignant pleural effusions (MPEs) are a frequent cause of dyspnea in patients with cancer. Although indwelling pleural catheters (IPCs) have been used since 1997, there are no studies of quality-adjusted survival following IPC placement. METHODS With a standardized algorithm, this prospective observational cohort study of patients with MPE(More)
BACKGROUND Bronchoscopy in patients with space-occupying brain lesions is anecdotally felt to carry a high risk of neurologic complications. METHODS We conducted a retrospective cohort study of patients with evidence of a malignant, space-occupying brain lesion who were referred for flexible or rigid bronchoscopy or endobronchial ultrasound-guided(More)
RATIONALE Data regarding the sensitivity of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for staging of lung cancer in patients with radiographic N0 disease is scant and inconsistent. With increasing use of nonoperative ablative therapies, studies focusing on the performance characteristics of EBUS-TBNA in this population are(More)
Solitary pulmonary nodules (SPNs) are commonly encountered in pulmonary practice. Their management is complex, and multiple clinical factors must be considered. The three common management strategies applied to solitary pulmonary nodules are careful observation, diagnostic testing, and surgery. Fundamental concepts derived from decision analysis can be used(More)
BACKGROUND Stereotactic body radiation therapy (SBRT) is considered the standard treatment for medically inoperable early stage lung cancer. Bronchoscopy has shown to be effective in obtaining diagnosis of peripheral lung tumors, staging the mediastinum (with endobronchial ultrasound- EBUS-), and placing fiducial markers (FMs). However, the combination of(More)
