The Solitary Lung Nodule:ABSTRACT: When a solitary lung nodule is detected, the key question is whether the lesion is malignant. The initial evaluation includes a careful history taking focused on risk factors for malignancy, a thorough physical examination, comparison of current chest films with previous ones, and CT scanning. Radiologic signs that suggest malignancy include lesion size greater than 2 cm in diameter, spiculated margins, lack of calcification, and change in size. Video-assisted thoracoscopic surgery or thoracotomy is the next step for patients with a suspected malignant lesion. If the results of the initial evaluation are equivocal, positron emission tomography (PET) scanning is the preferred follow-up.

Clinical Observations on West Nile Virus InfectionsIn 2004, 391 cases of West Nile virus (WNV) infection werereported in Arizona. This represented an epidemic thatchallenged area clinicians. We treated 34 patients with WNVinfection and reviewed their medical records. They werehospitalized at 3 community hospitals during the epidemic.These patients represented 9% of all WNV infection casesreported in Arizona. Meningitis was diagnosed in 13 patients,encephalitis in 12, fever of unknown origin in 5, transversemyelitis in 3, and carditis in 1. Respiratory failure requiringmechanical ventilation developed in 6 patients. Five of thesickest patients were empirically treated with interferon alfa 2band ribavirin. The epidemic and associated clinical challengesprompted evaluation of the available diagnostic and treatmentstrategies to optimize care of very ill patients. The consensusamong clinicians was that they were poorly prepared todiagnose and treat WNV infection in hospitalized patients.All patients survived hospitalization, although 4 patientsdied after discharge because of factors attributable to WNVinfection.
