Abstract
BACKGROUND There are no country-based data focused on aspirin (ASA)-exacerbated respiratory disease (AERD) in Turkey. OBJECTIVE To assess the prevalence of AERD in adult patients with asthma. METHODS A structured questionnaire was administered via face-to-face interview by a specialist in pulmonology/allergy at seven centres across Turkey. RESULTS A total of 1344 asthma patients (F/M: 1081/263: 80.5%/19.5%, mean age: 45.7 ± 14.2 years) were enrolled. Atopy rate was 47%. Prevalence of allergic rhinitis, chronic rhinosinusitis/rhinitis, and nasal polyposis (NP) were 49%, 69% and 20%, respectively. Of 270 patients with NP, 171 (63.3%) reported previous nasal polypectomy and 40 (25%) had a history of more than three nasal polypectomies. Aspirin hypersensitivity was diagnosed in 180 (13.6%) asthmatic patients, with a reliable history in 145 (80.5%), and oral ASA provocation test in 35 (19.5%) patients. Clinical presentations of ASA hypersensitivity were respiratory in 76% (n=137), respiratory/cutaneous in 15% (n=27), and systemic in 9% (n=16) of the patients. Multivariate analysis indicated that a family history of ASA hypersensitivity (p: 0.001, OR: 3.746, 95% CI: 1.769-7.929), history of chronic rhinosinusitis/rhinitis (p: 0.025, OR: 1.713, 95% CI: 1.069-2.746) and presence of NP (p<0.001, OR: 7.036, 95% CI: 4.831-10.247) were independent predictors for AERD. CONCLUSION This cross-sectional survey showed that AERD is highly prevalent among adult asthmatics and its prevalence seems to be affected by family history of ASA hypersensitivity, history of rhinosinusitis and presence of NP.

Abstract
BACKGROUND Aspirin (acetylsalicylic acid [ASA]) hypersensitivity is frequent in patients with nasal polyps (NPs) and is called aspirin exacerbated respiratory disease, previously known as Samter's syndrome. However, studies evaluating the prevalence of ASA hypersensitivity in patients with NPs using the oral aspirin provocation test (APT) are quite limited. This study was designed to determine the prevalence of ASA hypersensitivity and factors associated with ASA hypersensitivity in patients with NPs. METHODS Sixty-eight patients with NPs with or without asthma were recruited. Extension of NPs was evaluated by endoscopic examination/paranasal CT. A 2-day, single-blind placebo-controlled APT was used to detect ASA hypersensitivity. RESULTS APT was performed in 53 (21 women/ 32 men) patients (mean age, 39.34 ± 1.76 years). APT resulted positive in 12 patients (22.6%) of whom 3 (25%) had no history of ASA hypersensitivity. Of the positive APTs, three were isolated rhinitis and nine had classic responses. APT was negative in 41 patients (77.4%) although three (7.3%) had a history of ASA hypersensitivity. History of ASA hypersensitivity and prolonged duration of NPs were associated with positive APT (p < 0.05). Advanced NP with multiple operations was also correlated with APT positivity but was not statistically significant. Presence of asthma was associated with age, female gender, NP duration, and ASA hypersensitivity history (p < 0.05), but not with smoking, atopy, NP extension, and positive APT. CONCLUSION ASA hypersensitivity is quite common in patients with NP. Patients with extensive and long-term NP with multiple polyp operations require evaluation for the presence of ASA hypersensitivity in terms of chronic management and future risks of the disease.

Abstract
Non-opioid analgesics, antipyretics and nonsteroidal anti-inflammatory drugs are widely used, but suspected allergic reactions to these drugs are rare, especially in children. Most frequent reactions are cutaneous (urticaria, angioedema) and respiratory (rhinitis, asthma). Other reactions (anaphylaxis, potentially harmful toxidermias) are rare. In a few patients, reactions may result from a specific (allergic) hypersensitivity, with positive responses in prick and intradermal tests (anaphylaxis, immediate urticaria and/or angioedema) and in intradermal and patch tests (non-immediate reactions). However, most reactions result from a non-specific (non-allergic) hypersensitivity (intolerance), with a frequent cross-reactivity between the various families of analgesics, antipyretics and nonsteroidal anti-inflammatory drugs, including paracetamol. Based on a convincing clinical history and/or positive responses in challenge tests, intolerance to non-opioid analgesics, antipyretics and nonsteroidal anti-inflammatory drugs has been diagnosed in 13 to 50% of the patients with allergic-like reactions to these drugs. Risk factors are a personal atopy and age. Prevention is based on administration of other (families of) analgesics, antipyretics and nonsteroidal anti-inflammatory drugs in patients with allergic hypersensitivity to these drugs. In patients with non-allergic hypersensitivity, prevention is based on administration of drugs with a low cyclo-oxygenase-1 inhibitory activity (if tolerated). Desensitization is efficient in patients with respiratory reactions, but does not work in patients with mucocutaneous reactions and anaphylaxis.

Abstract
Allergic drug reactions compose a small percentage of ADRs, yet they are commonly encountered in clinical practice, and physicians are taught routinely to question patients about these reactions during history taking. Among antibiotics, the immunochemistry of penicillins has been elucidated,leading to the development of validated skin test reagents to diagnose type 1 allergy. Currently, the temporary commercial unavailability of Pre-Pen makes accurate penicillin skin testing impossible; however, this important skin test reagent is expected to become available sometime in 2006. Type 1 allergies to most other drugs lack comparable diagnostic tests, and their diagnosis is therefore driven by the patient's history. When readministration of medications to which patients report previous reactions is indicated, it may be almost always successfully accomplished by means of either graded challenge or desensitization.

Abstract
Aspirin-exacerbated respiratory disease (AERD) is an adult-onset condition that manifests as asthma, rhinosinusitis/nasal polyps, and sensitivity to aspirin and other cyclooxygenase-1 (COX-1)-inhibitor nonsteroidal anti-inflammatory drugs (NSAIDs). There is no cross-sensitivity to highly selective COX-2 inhibitors. AERD is chronic and does not improve with avoidance of COX-1 inhibitors. The diagnosis of AERD is made through provocative challenge testing. Following a positive aspirin challenge, patients can be desensitized to aspirin and NSAIDs. The desensitized state can be maintained indefinitely with continued daily administration. After desensitization, there is an approximately 48-hour refractory period to adverse effects from aspirin. The pathogenesis of AERD remains unknown, but these patients have been shown to have multiple abnormalities in arachidonic acid metabolism and in cysteinyl leukotriene 1 receptors. AERD patients can take up to 650 mg of acetaminophen for analgesic or antipyretic relief. Patients can also use weak COX-1 inhibitors, such as sodium salicylate or choline magnesium trisalicylate. Treatment of AERD patients with antileukotriene medications has been helpful but not preferential when compared with non-AERD patients. An alternative treatment for many AERD patients is aspirin desensitization. This is particularly effective in reducing upper-airway mucosal congestion, nasal polyp formation, and systemic steroids.

Abstract
Review of emergency department pain management practices demonstrates pain treatment inconsistency and inadequacy that extends across all demographic groups. This inconsistency and inadequacy appears to stem from a multitude of potentially remediable practical and attitudinal barriers that include (1) a lack of educational emphasis on pain management practices in nursing and medical school curricula and postgraduate training programs; (2) inadequate or nonexistent clinical quality management programs that evaluate pain management; (3) a paucity of rigorous studies of populations with special needs that improve pain management in the emergency department, particularly in geriatric and pediatric patients; (4) clinicians' attitudes toward opioid analgesics that result in inappropriate diagnosis of drug-seeking behavior and inappropriate concern about addiction, even in patients who have obvious acutely painful conditions and request pain relief; (5) inappropriate concerns about the safety of opioids compared with nonsteroidal anti-inflammatory drugs that result in their underuse (opiophobia); (6) unappreciated cultural and sex differences in pain reporting by patients and interpretation of pain reporting by providers; and (7) bias and disbelief of pain reporting according to racial and ethnic stereotyping. This article reviews the literature that describes the prevalence and roots of oligoanalgesia in emergency medicine. It also discusses the regulatory efforts to address the problem and their effect on attitudes within the legal community.

Abstract
Paracetamol (acetaminophen) is one of the over-the-counter analgesics that is used frequently for the self-management of some of the common disorders. There seems to be two types of relations between paracetamol and asthma - paracetamol intolerance leading to bronchospasm in analgesic-induced asthmatics; and the relation between asthma and the amount and frequency of consumption of paracetamol. Paracetamol is generally recommended as one of the safer analgesics in both analgesic tolerant and intolerant asthmatics, without the fear of severe bronchospasm that aspirin and other non-steroidal anti-inflammatory drugs can induce in these patients. However, Paracetamol is reported to cross-react with aspirin at a rate of approximately 20-30% in a dose-dependent way. Therefore, it should not be recommended to analgesic intolerant asthmatics, without performing oral provocation tests to prove its safety. The possible association between the amount and frequency of paracetamol consumption and the prevalence and degree of asthma as suggested by some of the recent surveys, needs to be investigated further.

Abstract
BACKGROUND Aspirin can provoke reactions ranging from respiratory to cutaneous in susceptible individuals. There has been particular attention looking at the role of cyclo-oxygenase enzymes 1 and 2 and their role in aspirin-exacerbated respiratory disease. OBJECTIVE Patients who present with a spectrum of allergic and pseudoallergic reactions to aspirin pose a special challenge for the physician. This article discusses proposed classification system, clinical manifestations, pathogenesis of disease, and current treatment options of aspirin-related disease. DATA SOURCES Relevant articles in the medical literature were derived from searching the MEDLINE database with key terms aspirin-sensitive asthma, cyclo-oxygenase enzymes 1 and 2. Sources also include review articles, randomized control trials, and standard textbooks of allergy and immunology. RESULTS Aspirin-exacerbated respiratory disease remains a complex, heterogenous disease with varied clinical presentations. There have been many advances in trying to elucidate the pathogenesis of this disease. The classification system presented will provide greater ease when reading the literature and communicating with one another. Oral aspirin challenge remains the diagnostic test of choice for both respiratory and cutaneous reactions. Aspirin desensitization is an option for those with refractory respiratory disease or who require aspirin for other medical conditions. CONCLUSIONS This review discusses the challenges in classification, diagnosis, and treatment of those patients with a sensitivity to aspirin. Special attention is made to the possible mechanisms mediating disease progression and how specific therapies, such as leukotriene modifiers, may be helpful.

Abstract
BACKGROUND Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome characterized by chronic rhinitis, nasal polyps, asthma, and precipitation of asthma and rhinitis attacks after ingestion of aspirin (ASA) and most nonsteroidal anti-inflammatory drugs (NSAIDs). Most information about the disease in the United States has come from small samples of patients. OBJECTIVE The purpose of this study was to examine the natural history and clinical characteristics of 300 AERD patients, referred to our institution for aspirin desensitization. METHODS All potential AERD patients were evaluated using a standard questionnaire that included information about clinical characteristics and natural progression of their disease, previous history of reactions to ASA and other NSAIDs, current use of medications, and ethnic backgrounds. All patients underwent oral ASA challenges to prove they had AERD. RESULTS From patients' history we found that the average age at onset of AERD was 34 years, and that 57% were female. Counting ASA as an NSAID, 33% had previously reacted on two occasions to NSAIDs and 36% on more than three occasions to NSAIDs, whereas only 27% had reacted to one NSAID before they came to us for evaluation. Our patients had averaged 5.5 episodes of sinusitis per year. There were no significant differences in the clinical characteristics or use of medications between genders. Ethnicity was heterogeneous in most participants. CONCLUSIONS AERD begins in the third decade of life and in both sexes. The disease progressed over the 13 years between historical onset and current evaluation, with more sinusitis and need for controller medications over time. There was no ethnic or familial distribution of AERD.
