A Differential Diagnosis of Drug-Induced Aseptic Meningitis

Drug-induced aseptic meningitis should be included in thedifferential diagnosis of viral/aseptic meningitis. Cliniciansshould use historical clues in patients presenting with signs andsymptoms of viral meningitis to aid in the differentiation ofdrug-induced aseptic meningitis from other causes of asepticmeningitis. Viruses are the most common cause of asepticmeningitis, with enteroviruses being the most common amongviruses in cases presenting as aseptic meningitis. Ibuprofen iscurrently the most common cause of drug-induced asepticmeningitis. Drug-induced aseptic meningitis is a benign conditionwithout long-term sequelae. The diagnosis of druginducedaseptic meningitis is made by establishing a causalrelationship between the use of the drug and the onset of signsand symptoms, supported by negative tests for infectiouscauses of symptoms and rapidity of resolution after the drugis discontinued.

Bleeding of any kind in a postmenopausal patient should be considered abnormal unless she is receiving hormonal therapy that is associated with regular cyclic withdrawal bleeding.

Clinical Investigation

The CDC estimates that more than 850,000 people are living with HIV/AIDS in the United States today,1 with African Americans and Latinos being disproportionately affected.2 Over the past decade, the Latino population in the United States has been growing. In fact, in 2002 for the first time, Latinos surpassed African Americans as the largest US minority group. However, the term "Latino" is applied to a very heterogeneous group from different countries and different cultures.3 In addition, a large proportion of Latinos is undocumented in the United States and thus marginalized from the health care system.

Arterial blood gas analysis: A 3-step approach to acid-base disorders

The foundation of arterial blood gas (ABG) analysisconsists of determining whether the patient has acidosis or alkalosis;whether it is a respiratory or metabolic process; and,if respiratory, whether it is a pure respiratory process. If the patient'spH and PCO2 are increased or decreased in the same direction,the process is metabolic; if one is increased while theother is decreased, the process is respiratory. In a number ofclinical situations, pulse oximetry is preferred to ABG analysis.However, pulse oximetry may not be accurate in patients whoare profoundly anemic, hypotensive, or hypothermic. Whilevenous blood gas (VBG) analysis does not provide any informationabout the patient's oxygenation, it can help assessthe level of acidosis or alkalosis. VBG analysis may be particularlyuseful in patients with diabetic or alcoholic ketoacidosis.(J Respir Dis. 2008;29(2):74-82)

Clinical Observations on West Nile Virus Infections

In 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.

Metallic Corneal Foreign Body With Rust Ring

Two days after "heading" a soccer ball, a 17-year-old boy presented to the emergency department with progressive pain and a foreign-body sensation in his left eye. Visual acuity was 20/20 in the right eye and 20/25 in the left eye. The pupils were equally round and reactive; full extraocular movements of both eyes were noted. The left eye had conjunctival injection and a 1-mm foreign body on the medial cornea with a surrounding halo of discoloration--typical of a metallic corneal foreign body. A Seidel test (which demonstrates streaming of fluorescein dye from the aqueous humor when illuminated with UV light) revealed no evidence of corneal perforation; there were noareas of fluorescein dye uptake.
