Assessing the risk of crashes in patients with obstructive sleep apneaABSTRACT: Patients with obstructive sleep apnea (OSA) are at increasedrisk for motor vehicle crashes as a result of excessivesleepiness. However, a number of factors complicate risk assessment.For example, self-reported sleepiness and the severityof OSA do not appear to be good predictors of accident risk.Many persons with OSA do not accurately perceive their levelof drowsiness-self-reported sleepiness does not correlate wellwith objective measures, such as results of the Multiple SleepLatency Test. Moreover, it is not clear whether objective testscan reliably predict accident risk in the real world, as opposedto during simulated driving. The indications for-and benefitsof-restricting driving in patients with OSA have not been established.However, there is good evidence that the use of continuouspositive airway pressure significantly reduces the riskof crashes in these patients.

Exercise for Patients with Osteoarthritis: A Phased Approach to PlannngABSTRACT: Exercise can be an effective way to stabilize or slow the degenerative process of osteoarthritis-provided convenient, safe, and enjoyable activities are selected and achievable goals are set. Implement an osteoarthritis exercise plan in phases, and progress gradually from one phase to the next; this will help both you and your patient anticipate difficulties and gauge progress. The first phase-the initial evaluation-includes gathering baseline data, targeting an area of the body to focus on first, and identifying potential contraindications to activities. Subsequent phases include range of motion exercises (stretching), isometric and isotonic strengthening exercises, and recreational or functional activities. Encourage patients to continue stretching exercises throughout the program.

Update on the Therapy for SporotrichosisSporotrichosis is a fungal infection that typically results in cutaneous or lymphocutaneous disease, although other, more severe, life-threatening manifestations do occur. This article reviews updated treatment guidelines, which state that itraconazole has become the preferred therapy for most forms of infection. Amphotericin B remains the mainstay of treatment for severe cases, but lipid formulations are now preferred because of their more favorable toxicity profile. Also, fluconazole has been shown to be less effective than itraconazole and is no longer recommended except as an alternative for cutaneous and lymphocutaneous disease.

The technique of adult flexible bronchoscopy: Part 1ABSTRACT: Flexible bronchoscopy was clinically introduced byShigeto Ikeda in 1968 and is now used widely for diagnosticand therapeutic interventions. A combination of advancingtechnology and ingenuity has fostered the development of anexpanded array of devices and applications. The newer videobronchoscopes offer higher-resolution images than fiberopticbronchoscopes. The advantages of fiberoptic technology arelower cost and greater technical ease of adapting to smallerdiameterbronchoscopes. Hybrid bronchoscopes have an imaginglens and fiberoptic bundles that transmit the viewingimage to a charge couple device (CCD) chip in the body of theoperator end of the bronchoscope. The digital image is transmittedfrom the CCD chip to the external processor for viewingon a monitor, for digital storage, or for printing. (J Respir Dis.2008;29(11):423-428)

Celiac Disease: Could You Be Missing This Diagnosis?ABSTRACT: Only a small number of patients with celiac disease exhibit the textbook symptoms of malabsorptive diarrhea with steatorrhea, weight loss, and nutritional deficiencies. Others may present with a subclinical enteropathy, GI complaints without constitutional symptoms, persistent travelers' diarrhea, or extraintestinal manifestations alone. Be alert for suggestive signs, such as weight loss, skin lesions, oral aphthae, muscle atrophy, de-enamelization of the teeth, and vague GI symptoms, such as bloating. Helpful serologic tests include IgG and IgA antigliadin antibodies, enzyme tissue transglutaminase antibodies, antiendomysial antibodies, and total IgA. Typical endoscopic findings are mucosal atrophy, fissuring, and scalloping. In addition to a gluten-free diet, management encompasses repletion of vitamins and minerals, including iron, folate, calcium, and vitamin D; screening for thyroid disease and diabetes mellitus; bone densitometry and age-appropriate cancer screening; and pneumococcal vaccination.

Three days later, a pruritic rash appeared on his back, then spread to the chest, lower legs, and face. He stopped the celecoxib on his own and self-administered diphenhydramine for the pruritus. The rash and itch persisted, which prompted the patient to seek medical care. He had no respiratory symptoms.

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.
