Introduction: Live attenuated zoster vaccine (Zostavax) was used to test the hypothesis that constitutive level of interleukin 10 (IL-10), which may be high in elderly subjects, impairs vaccine efficacy. If constitutive IL-10 impairs vaccine efficacy, the effectiveness of viral vaccines might be improved by transient inhibition of IL-10 before vaccination.

Methods: Zostavax was given to 26 patients (age, 60-80 years).

Opioid addiction is a world-wide tragedy, with severe consequences for both the victims and the society that must care for them. The pathways to addiction are multiple but postoperative opioid prescriptions for pain management are a major contributor to this crisis. This case report describes the differences in pain management during 2 different arthroplasties of the knees in the same person.

Aspirin-exacerbated respiratory disease is defined by the clinical tetrad of aspirin sensitivity, nasal polyps, asthma, and chronic rhinosinusitis. Patients experience acute upper and lower airway reactions with exposure to aspirin and other cyclooxygenase-1 inhibiting medications. However, airway inflammation and disease progression occur even in the absence of exposure to these medications, often leading to aggressive polyp formation and need for systemic corticosteroids to treat exacerbations in asthma and rhinosinusitis.

Aspirin-exacerbated respiratory disease is a significant endotype of both asthma and chronic rhinosinusitis with nasal polyps. The disease demonstrates what seems to be a unified inflammatory mechanism culminating in highly eosinophilic nasal polyp disease and asthma. The rate of polyp recurrence and morbidity from asthma exacerbations are significant and warrant separating this group diagnostically from aspirin-tolerant peers.

Background: Aspirin-exacerbated respiratory disease (AERD) is manifested by adult-onset asthma, nasal polyposis, chronic rhinosinusitis, and aspirin sensitivity. Previously reported prevalence rates have been widely variable based on the population studied, method of diagnosis, and definition of aspirin sensitivity.

Objective: We sought to determine the prevalence of AERD among asthmatic adults.

Background: Nasal ketorolac challenge with modified oral aspirin challenge is a safe and effective alternative for desensitizing patients with aspirin-exacerbated respiratory disease. In addition to clinical judgment, objective tests assessing nasal flow may help in diagnosing nasal reactions.

Objective: To evaluate the feasibility of peak nasal inspiratory flow (PNIF) as an objective measurement in the assessment of a reaction to nasal ketorolac and to determine changes in PNIF that have adequate sensitivity and specificity.

Aspirin desensitization is a treatment option for patients with aspirin-exacerbated respiratory disease (AERD). Some patients with an excellent history of aspirin or nonsteroidal anti-inflammatory drug (NSAID) reactions have negative aspirin challenges/desensitization. This study discusses the clinical entity of silent desensitization in AERD and the dilemma that this presents to the practicing allergist/immunologist.

Although aspirin desensitization was discovered in 1922, it was not until 1979 that a therapeutic use for aspirin treatment, under the protection of desensitization, was discovered. In the last 33 years, details of aspirin treatment have been refined to the point where it is now recognized and accepted as a major therapeutic intervention in the treatment of aspirin-exacerbated respiratory disease, with therapeutic efficacy in approximately two-thirds of patients. It is only effective in patients who have aspirin-exacerbated respiratory disease and none of the other nonsteroidal anti-inflammatory drugs, despite their cross-reactive inhibition of cyclooxygenase-1, can effectively take the place of aspirin.

Hypersensitivity reactions to NSAIDs may occur in susceptible individuals and vary in symptom (skin, respiratory tract, and solid organs), severity (from mild skin or respiratory reactions to severe generalized) and timing (from acute to delayed). The current classification of NSAID-induced reactions emerged with the understanding of the pathologic mechanism of reactions to NSAIDs which may be either non-allergic (related to cyclooxygenase inhibition) or immunologically mediated. In this chapter we discuss the implications of accurate NSAIDs hypersensitivity classification for proper diagnosis and patient management.

The occurrence of an emergent need for aspirin therapy in an aspirin or nonsteroidal anti-inflammatory drug (NSAID)-"allergic" individual presents one of the more challenging situations the allergist may face. A common request is for the allergist to evaluate an acutely ill patient in a monitored hospitalized setting with a vague and remote history of a "reaction to aspirin." Because of significant diagnostic limitations, introducing aspirin can be very difficult.

Background: Aspirin prevents coronary thrombosis and is used extensively in cardiovascular prophylaxis. However, patients with a prior history of an aspirin "reaction" are routinely denied this medication.

Objective: To characterize the clinical presentation of a cohort of patients with coronary artery disease (CAD) and aspirin reactions.

Aspirin-exacerbated respiratory disease (AERD) is a unique syndrome of airway inflammation that frequently occurs in patients with nasal polyposis, chronic sinusitis, and asthma. These patients tend to have progressive and recalcitrant sinus disease requiring frequent surgical intervention and in many cases systemic corticosteroids. Much about the pathogenesis of AERD remains unclear, but environmental factors likely play a prominent role in its development.

Aspirin-exacerbated respiratory disease (AERD) is characterized by adult onset of asthma, chronic rhinosinusitis (CRS), nasal polyposis, and aspirin sensitivity. In this syndrome, each disease component has deleterious effects on the patient's health and quality of life. Latest figures from the Centers for Disease Control indicate 8.

Background: Tobacco smoke is a widely recognized environmental pollutant and is a major public health hazard worldwide. Although environmental tobacco smoke (ETS) has a clear link with many conditions, including asthma, ear infections, and sinus cancer, evidence related to aspirin-exacerbated respiratory disease (AERD) requires further investigation.

Objective: To investigate whether active smoke or ETS exposures are associated with an increased risk of developing AERD.

Pelvic abscesses occurring after gynecologic pelvic surgery are uncommon. We describe the case of a woman who, after undergoing such a procedure, was found to have pelvic abscesses infected with methicillin-resistant Staphyloccocus aureus. The purpose of this report is to raise awareness of a life-threatening complication of gynecologic pelvic surgery.
