A Differential Diagnosis of Drug-Induced Aseptic MeningitisDrug-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.

Respiratory symptoms may develop years after IBD diagnosis What are the pulmonary manifestations of inflammatory bowel disease? key words: Inflammatory bowel disease, Ulcerative colitis, Crohn disease, Bronchiectasis, BOOP, Interstitial pneumonitisabstract: Inflammatory bowel disease (IBD) can have a variety of extraintestinal manifestations, including pulmonary disease. Bronchial involvement is the most common, but other manifestations include upper airway disease; parenchymal involvement, such as bronchiolitis obliterans with organizing pneumonia (BOOP) and interstitial lung disease; and serositis, including pleural effusions and pericarditis. Patients with BOOP may present with fever, dyspnea, cough, and pleuritic chest pain. Chest radiographs show bilateral patchy airspace opacities or a diffuse process; CT scans often demonstrate the opacities to be pleural-based. Corticosteroids appear to be effective in the management of certain pulmonary manifestations of IBD, such as BOOP and pulmonary infiltrates with eosinophilia. (J Respir Dis. 2007;28(6):227-234)
