Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a highly prevalent and burdensome disease for both individuals and health systems. Its management involves many specialties, including otorhinolaryngology, allergology, pulmonology, primary care, pharmacy, and pediatrics. A multidisciplinary approach and the participation of the patient in decision-making are essential, both for diagnosis and for therapy. The authors of the consensus aim to translate current knowledge into an easy-to-read practical guide and emphasize those aspects requiring further discussion or with unmet needs owing to the lack of appropriate scientific evidence. An iterative approach for the development of an evidence-based systematic review with recommendations was followed using a standard quality assessment approach (Scottish Intercollegiate Guidelines Network [SIGN] and National Institute for Health and Care Excellence [NICE]). The guideline was critically evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE II) and Recommendation Excellence (AGREE REX) instruments. Consequently, POLINA has been considered a high-quality guideline by an independent agency. The POLINA consensus provides new definitions of control, therapeutic management (including surgery and evaluation of severity), indications for use of biologics, and response. Finally, this guideline focuses on unmet research needs in CRSwNP.

Abstract
Summary Objective. The association of allergic conjunctivitis (AC) with rhinitis and/or asthma is poorly understood. The objective of this study was to apply the Consensus Document for Allergic Conjunctivitis (DECA) criteria for the classification of AC to a population of patients with AC to assess the association between the severity and duration of AC and rhinitis and/or asthma. Methods. Patients with ocular symptoms of AC who participated in the 'Alergológica 2015' study were included. The demographics, classification according to the DECA criteria, etiology, and comorbidities were evaluated by age groups (less or equal than 14 and greater than 14 years). Results. A total of 2,914 patients (age range, 1-90 years) were included in the "Alergológica 2015" study. Of these, 965 patients (33.1%) were diagnosed with AC (77.5% > 14 years). AC was classified as severe, moderate, or mild in 1.8%, 46.4%, and 51.8%, respectively; and as intermittent or persistent in 51.6% and 48.4% of the patients. AC alone occurred in 4% of patients. AC was mainly associated with rhinitis (88.4%), asthma (38.2%), food allergy (8.3%) and atopic dermatitis (3.5%). In allergic respiratory disease rhinitis preceded AC and asthma developed later. The severity and duration of AC was significantly associated with severity and duration of rhinitis (p less than 0.001 for both age groups) and asthma (p less than 0.001 only in adults). Conclusions. The application of the new DECA classification for AC reveals a direct relationship between AC, rhinitis and asthma respect to severity and duration. These relationships suggest that AC should be considered an integral part of the "one airway, one disease" hypothesis.

Abstract
INTRODUCTION AND OBJECTIVE Since the early stages of the novel coronavirus 2019 (SARS-CoV-2) outbreak, smell and/or taste dysfunction (STD) has been reported in 5% to 88% of COVID-19 patients. Objective: We aimed to assess STD in health care professionals (HCPs), mainly allergists, affected by COVID-19. We carried out a survey to evaluate the association between STD and its severity and demographic characteristics, symptoms, comorbidities, and hospital admission. METHODS We designed a 15-item questionnaire comprising various sections, as follows: demographics, diagnostic characteristics, STD patterns, medication use, and comorbidities. The questionnaire was developed using Google forms. It was distributed to members of the Spanish Society of Allergology and Clinical Immunology (SEAIC) and sent via social media to be completed by HCPs with COVID-19. RESULTS The survey was completed by HCPs (n=234), of whom 76.5% were aged ≤55 years and 73.5% were female. STD was detected in 74.4% of respondents, of whom 95.6% reported moderate-severe impairment. Mean time until recovery of taste dysfunction was 21.6 (24.0) days in HCPs aged ≤55 years and 33.61±26.2 days in those aged >55 years (P=.019). Analysis stratified by severity of STD showed that more than a half of COVID-19 patients presented severe loss of smell. Older age (>55 years) was associated with fever, anorexia, lower frequency of headache, and longer persistence of taste dysfunction. CONCLUSION STD is a common symptom in COVID-19, even as a unique or preceding symptom. HCPs who reported smell dysfunction were younger than those not affected with STD. Taste dysfunction may imply more systemic involvement in COVID-19-positive HCPs.

Abstract
INTRODUCTION Eosinophilic oesophagitis (EoE) is a chronic clinical-pathological disorder with an immunological basis characterised by symptoms of oesophageal dysfunction and, histologically, eosinophilic inflammation. OBJECTIVE To evaluate the clinical characteristics and differences in children and adults diagnosed with EoE in a tertiary level hospital. METHOD Descriptive, retrospective and cross-sectional study. We randomly selected 40 children and 40 adults diagnosed with EoE between 2009 and 2016. The patient characteristics were analysed by means of epidemiological, clinical, diagnostic and therapeutic variables. RESULTS The average age at diagnosis was 10 years (children) and 34 years (adults), with a higher frequency in males. The majority were sensitised to aeroallergens (77.5% children vs. 82.5% adults) and foods (75% children vs. 82.5% adults). Statistically significant differences were detected in sensitisation to fruits (p=0.007) and grains (p<0.001). Differences were observed in impaction (22.5% children vs. 82.5% adults), dysphagia (42.5% children vs. 77.5% adults) and abdominal pain (25% children vs. 7.5% adults). Endoscopy showed that children had a higher frequency of exudates (92.5%) and adults, trachealisation (50% vs. 5%) and stenosis (17.5% vs. 2.5%). Statistically significant differences were found in treatment with topical corticosteroids (30% children vs. 77.5% adults), with a variable positive response. 77.5% of the patients received elimination diets. CONCLUSIONS Statistically significant differences were observed between the paediatric and adult populations in the food sensitisation profiles, clinical manifestations, endoscopic findings and treatments received. This is a complex pathology that calls for a multidisciplinary team and would require new non-invasive techniques to facilitate its management.

Abstract
BACKGROUND AND OBJECTIVE The Rhinitis Control Assessment Test (RCAT) is a patient-based questionnaire that is widely used to evaluate control of rhinitis. Objective: To develop and validate a Spanish version of the RCAT (RCATe). METHODS After translation and cultural adaptation of the original RCAT, this multicenter, observational, prospective study evaluated the properties/attributes of the RCATe by assessing its validity, reliability, responsiveness, effect size, minimal important difference and cut point. RESULTS The recruited sample comprised 252 allergic rhinitis (AR) patients from 27 allergy and otolaryngology departments in hospitals throughout Spain. Significant and strong correlations were found between the RCATe and the total nasal symptom score and the visual analog scale (-0.79 and -0.77, respectively; P<.0001). The RCATe revealed significant differences between patients grouped in the different categories of severity or duration of AR (P<.001). The internal consistency (Cronbach α) was good (0.84), and the test-retest reliability was moderate (0.54 evaluated by the physician and 0.49 by the patient). The responsiveness to change was high and significant for RCATe (P<.0001) and correlated linearly with the improvement in AR. The overall effect size was 1.62. The cut-off point to identify patients with adequate control of AR was >20 (area under the receiver operating characteristic curve, 0.746; sensitivity, 58.3%; specificity, 90.9%). CONCLUSION The psychometric evaluation and validation of the RCATe indicated good reliability, validity, and responsiveness, thus suggesting that it is effective for measuring control of AR symptoms by Spanish-speaking patients.

Abstract
Nasal obstruction (NO) is defined as the subjective perception of discomfort or difficulty in the passage of air through the nostrils. It is a common reason for consultation in primary and specialized care and may affect up to 30%-40% of the population. It affects quality of life (especially sleep) and lowers work efficiency. The aim of this document is to agree on how to treat NO, establish a methodology for evaluating and diagnosing it, and define an individualized approach to its treatment. NO can be unilateral or bilateral, intermittent or persistent and may be caused by local or systemic factors, which may be anatomical, inflammatory, neurological, hormonal, functional, environmental, or pharmacological in origin. Directed study of the medical history and physical examination are key for diagnosing the specific cause. NO may be evaluated using subjective assessment tools (visual analog scale, symptom score, standardized questionnaires) or by objective estimation (active anterior rhinomanometry, acoustic rhinometry, peak nasal inspiratory flow). Although there is little correlation between the results, they may be considered complementary and not exclusive. Assessing the impact on quality of life through questionnaires standardized according to the underlying disease is also advisable. NO is treated according to its cause. Treatment is fundamentally pharmacological (topical and/or systemic) when the etiology is inflammatory or functional. Surgery may be necessary when medical treatment fails to complement or improve medical treatment or when other therapeutic approaches are not possible. Combinations of surgical techniques and medical treatment may be necessary.

Abstract
BACKGROUND Despite the socioeconomic importance of allergic rhinitis (AR), very few prospective studies have been performed under conditions of clinical practice and with a sufficiently long observation period outside the clinical trial scenario. We prospectively estimated the direct and indirect costs of AR in patients attending specialized clinics in Spain. METHODS Patients were recruited at random from allergy outpatient clinics in 101 health centers throughout Spain over 12 months. We performed a multicenter, observational, prospective study under conditions of clinical practice. We analyzed direct costs from a funder perspective (healthcare costs) and from a societal perspective (healthcare and non-healthcare costs). Indirect costs (absenteeism and presenteeism [productivity lost in the workplace]) were also calculated. The cost of treating conjunctivitis was evaluated alongside that of AR. RESULTS The total mean cost of AR per patient-year (n = 498) was €2326.70 (direct, €553.80; indirect, €1772.90). Direct costs were significantly higher in women (€600.34 vs €484.46, P = 0.02). Total costs for intermittent AR were significantly lower than for persistent AR (€1484.98 vs €2655.86, P < 0.001). Total indirect costs reached €1772.90 (presenteeism, €1682.71; absenteeism, €90.19). The direct costs of AR in patients with intermittent asthma (€507.35) were lower than in patients with mild-persistent asthma (€719.07) and moderate-persistent asthma (€798.71) (P = 0.006). CONCLUSIONS The total cost of AR for society is considerable. Greater frequency of symptoms and more severe AR are associated with higher costs. Indirect costs are almost threefold direct costs, especially in presenteeism. A reduction in presenteeism would generate considerable savings for society.

Abstract
OBJECTIVE Examine the prevalence of asthma and associated predictive factors in a group of 468 students. PATIENTS AND METHODS A descriptive, cross-sectional observational study in a randomly selected population of 468 children aged 10-12, in the city of Zaragoza. We used the ISAAC questionnaire on asthma completed by children under supervision of the investigators. We assessed the genetic risk (family history of asthma) and environmental risks. The risk for atopy was assessed by the presence of positive skin prick tests. RESULTS 25.3% of the children had symptoms consistent with asthma in the city of Zaragoza. Among them 33.1% reported a history of asthma in close relatives (OR=1.78, p<0.001). The history of hospitalisations for lower respiratory tract illness was strongly associated with the presence of asthma (OR=6.72, p<0.0001). Positive skin tests to Alternaria (OR=2.00, p<0.0001) and grass pollen (OR=1.76, p<0.001) were predictors of asthma. 63.6% of asthmatic children had presented clinical rhinitis in the previous 12 months, compared with 32% of non-asthmatics, and this difference was statistically significant (OR=3.89, p<0.0001). 47% of asthmatics presented with or previously had eczema, whereas only 26.9% of non-asthmatics presented with or previously had these types of lesions (p<0.0001). CONCLUSION The following are predictors of asthma: History of hospital admissions for lower respiratory tract illness, presence of rhinitis and/or eczema, positive prick test for certain aeroallergens, especially Alternaria and grass pollen, and family history of asthma.

Abstract
Food allergy and respiratory allergy are two frequently associated diseases and with an increasing prevalence. Several reports show the presence of respiratory symptoms in patients with food allergy, while certain foods may be related to the development or exacerbation of allergic rhinitis and asthma. The present update focuses on this relationship, revealing a pathogenic and clinical association between food and respiratory allergy. This association is even more intense when the food hypersensitivity is persistent or starts in the early years of life. Food allergy usually precedes respiratory allergy and may be a risk factor for allergic rhinitis and asthma, becoming a relevant clinical marker for severe atopic asthma. Furthermore, the presence of co-existing asthma may enhance life-threatening symptoms occurring during a food allergic reaction. Recommendations for dietary restrictions during pregnancy and breastfeeding to prevent the development of respiratory allergy are controversial and not supported by consistent scientific data. Current recommendations from medical societies propose exclusive breastfeeding during the first four months of life, with the introduction of solid food in the fourth to the seventh month period of life. A delayed introduction of solid food after this period may increase the risk of developing subsequent allergic conditions. Further studies are encouraged to avoid unjustified recommendations involving useless dietary restrictions.

Abstract
Nasal hyperreactivity is the abnormal reaction of nasal tissue to a stimulus that is innocuous to most people. This response is caused by dysregulation of the autonomic nervous system at various levels of the nasal autonomic reflex arc. Various stimuli (methacholine, histamine, adenosine 5'-monophosphate, cold air, mannitol, rapsaicin, phentolamine, and distilled water) have been used in an attempt to find the test that most reliably differentiates between healthy individuals and patients and also between different types of rhinitis. Despite the small number of publications available, in the present review, we provide an update on current nonspecific nasal provocation techniques. The studies published to date are not comparable: the stimuli applied act through different mechanisms and are used to assess different pathways, and the methodologies differ in terms of selection of participants, concentrations used, and assessment of response (criteria for positivity). Given the limited use of nonspecific nasal provocation tests in routine clinical practice, we believe that more studies are warranted to address the research issues we present at the end of the present review, for example, the need to standardize the methodology for each test or even the clinical benefits of knowing whether or not a patient has nasal hyperreactivity.

Abstract
Allergic conjunctivitis (AC) is an inflammatory disease of the conjunctiva caused mainly by an IgE-mediated mechanism. It is the most common type of ocular allergy. Despite being the most benign form of conjunctivitis, AC has a considerable effect on patient quality of life, reduces work productivity, and increases health care costs. No consensus has been reached on its classification, diagnosis, or treatment. Consequently, the literature provides little information on its natural history, epidemiological data are scarce, and it is often difficult to ascertain its true morbidity. The main objective of the Consensus Document on Allergic Conjunctivitis (Documento dE Consenso sobre Conjuntivitis Alérgica [DECA]), which was drafted by an expert panel from the Spanish Society of Allergology and Spanish Society of Ophthalmology, was to reach agreement on basic criteria that could prove useful for both specialists and primary care physicians and facilitate the diagnosis, classification, and treatment of AC. This document is the first of its kind to describe and analyze aspects of AC that could make it possible to control symptoms.

Abstract
BACKGROUND Nasal polyposis (NP) is a chronic inflammatory disease that constitutes a major health problem with significant comorbidities and a considerable associated socioeconomic burden. OBJECTIVE To describe the clinical features and management of patients with NP attending Spanish allergy centers, the use of health care resources, and the degree of compliance with the diagnostic and therapeutic recommendations of the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS). METHODS We performed a multicenter, observational, and cross-sectional epidemiologic study of 671 patients consulting for NP in 67 Spanish allergy departments. We used sociodemographic and clinical questionnaires to evaluate clinical characteristics, use of health care resources, diagnostic methods, and treatment administered. RESULTS NP was closely associated with asthma (66%), allergic rhinitis (45.9%), and hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) (26%). Atopy was present in the 50% of cases, with Dermatophagoides pteronyssinus as the most frequent sensitizing allergen. Eleven percent of NP patients visited the emergency department during the previous year, and more than 58% used primary care, allergy, or otorhinolaryngology services. The most frequently used diagnostic tests were skin prick tests (93.6%) and anterior rhinoscopy (79.4%). Intranasal corticosteroids were the drug class most frequently prescribed by allergists (74.6%). Specific immunotherapy was prescribed in 21% of patients. CONCLUSIONS NP is a chronic inflammatory disease that generates considerable use of health care resources. The close association with atopy, asthma, and NSAID hypersensitivity highlights the usefulness of an allergy workup in all patients with NP. Analysis of the clinical management of NP by allergists in Spain revealed a high degree of compliance with EPOS diagnostic and therapeutic recommendations.

Abstract
The Amaranthaceae family is composed of about 180 genera and 2500 species. These common weeds have become increasingly relevant as triggers of allergy in the last few years, as they are able to rapidly colonize salty and arid soils in extensive desert areas. The genera Chenopodium, Salsola, and Amaranthus are the major sources of pollinosis from the Amaranthaceae family in southern Europe, western United States, and semidesert areas of Saudi Arabia, Kuwait, and Iran. In Spain, Salsola kali is one of the most relevant causes of pollinosis, together with olive and grasses. To date, 9Amaranthaceae pollen allergens from Chenopodium album, Salsola kali, and Amaranthus retroflexus have been described and are listed in the International Union of Immunological Societies allergen nomenclature database.The major allergens ofAmaranthaceae pollen belong to the pectin methylesterase, Ole e 1-like, and profilin panallergen families, whereas the minor allergens belong to the cobalamin- independent methionine synthase and polcalcin panallergen families. These relevant allergens have been characterized physicochemically, and immunologically at different levels. Recombinant forms, allergenic fusion recombinant proteins, and hypoallergenic derivatives of these allergens have been expressed in bacteria and yeast and compared with their natural proteins from pollen. In this review, we provide an extensive overview ofAmaranthaceae pollen allergens, focusing on their physicochemical, and immunological properties and on their clinical significance in allergic patients. We also review studies where these recombinant allergens and their hypoallergenic derivatives have been used in clinical diagnosis and their potential use in personalized therapy.

Abstract
OBJECTIVE ESPRINT-15 is a specific and validated instrument to measure health-related quality of life in adults with allergic rhinitis. The aim of this study was to obtain new reference values based on disease severity using both the original and the modified versions of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. METHODS ESPRINT-15 was administered to a representative sample of adults with allergic rhinitis in Spain. As in a previous study by our group, means and percentiles were analyzed for 16 quotas based on gender, allergic rhinitis type (intermittent vs persistent), and 4 symptom intensity groups according to the total symptom score (TSS4). The novel aspect of the present study was our application the severity criteria proposed by both the original and the modified ARIA classifications. RESULTS Of the 2756 patients in our previous dataset, 2580 were included in the present analysis. In terms of symptom severity, women ha relatively more intense symptoms than men with both ARIA classifications. In fact, using only the modified ARIA classification, we were abl to determine that severe rhinitis is moderately more frequent in women (27% vs 23%), although the difference is not statistically significant. CONCLUSIONS The new set of reference values enables the ESPRINT-15 questionnaire to be adapted to the current severity classification Consequently, this quality of life tool (http://www.seaic.org/inicio/esprint) can be easily used and better interpreted in daily clinical practice.

Abstract
BACKGROUND Sleep is impaired in allergic rhinitis (AR) patients, with subsequent effects on daytime performance and health-related quality of life (QOL). Sleep quality in AR has rarely been considered through validated tools and consensus classifications. OBJECTIVE To evaluate sleep quality and daytime somnolence in AR patients, and to estimate its relationship to disease severity according to Allergic Rhinitis and Its Impact on Asthma (ARIA) conventional and modified classifications, as well as in terms of QOL and comorbidities. METHODS Allergic rhinitis adult patients were evaluated through a prospective, observational, multicentre survey in Spain. Symptoms were assessed using the Total Symptoms Score (TSS), specific QOL by the Rhinitis Quality of Life Questionnaire (RQLQ), sleep quality by Pittsburgh scale, and diurnal somnolence by a scale based on Epworth's, all recorded in a unique visit. RESULTS A total of 2275 patients were included. According to ARIA criteria, 50.2% had persistent and 49.8% intermittent rhinitis, whereas 87.6% were classified as moderate-severe and 12.4% as mild; 52.8% had poor sleep quality, with a global median score for Pittsburgh scale of 6 (normal < 5) and 21.1% suffered from excessive diurnal somnolence. Correlation between Pittsburgh scale and RQLQ was moderate (r = 0.54). Among symptoms, nasal obstruction and concomitant asthma mainly, contributed to bad sleep quality. In a logistic regression model, moderate-severe rhinitis and nasal obstruction were all associated with a worse sleep quality. CONCLUSIONS AND CLINICAL RELEVANCE Sleep quality is altered in AR patients. Sleep quality was worse in moderate-severe, and particularly in severe AR. Nasal obstruction and RQLQ deterioration are associated with a poorer sleep quality. Sleep impairment is common in allergic rhinitis, particularly in more severe forms. Nasal obstruction and concomitant asthma should be considered as contributing factors. CAPSULE SUMMARY This is a large epidemiological survey of patients with allergic rhinitis showing a strong relationship between disease severity, as assessed by a consensus classification, and sleep impairment, as measured by a validated sleep quality tool.

Abstract
Specific nasal provocation testing (NPT) consists of eliciting a response from the nasal mucosa by controlled exposure to allergens. It is indicated in the diagnostic confirmation of allergic rhinitis and when discrepancies arise or difficulties exist in the assessment of a patient's medical history and the results of skin and/or serological tests. The technique is also applied to evaluate sensitivity to the allergen, the efficacy and safety profile of treatment, and in research on the pathophysiological mechanisms of nasal response to allergens. NPT also provides information on the etiology of occupational respiratory diseases of allergic origin. Although there have been many studies and publications on the use and standardization of bronchial provocation tests with allergen, few analyze specific NPT. In this review, the Rhinoconjunctivitis Committee of the Spanish Society of Allergy and Clinical Immunology discuss the methodology, monitoring, and assessment of allergen-specific NPT in order to provide a practical and up-to-date review of the technique.

Abstract
BACKGROUND Allergic rhinitis (AR) is a common disease with major socioeconomic burden and a significant impact on quality of life. OBJECTIVE The aim of this study was to discriminate between moderate and severe AR patients whether receiving treatment or not, using a modified criterion of allergic rhinitis and its impact on asthma (ARIA) classification. METHODS The modified ARIA severity classification (J Allergy Clin Immunol, 120, 2007, 359) categorizes AR as mild (no items affected), moderate (1-3 items affected), and severe (all four items affected). We applied these criteria to 1666 treated and 1058 untreated AR patients and compared their symptoms total four-symptom score (T4SS) and quality of life (ESPRINT-15), according to their clinical severity. RESULTS Allergic rhinitis clinical status was significantly worse (P < 0.001) in treated than in untreated patients. For both treated and untreated patients, T4SS and ESPRINT-15 Quality of life scores were significantly worse (P < 0.001) in severe than in moderate patients. CONCLUSIONS The modified ARIA severity classification is a useful clinical tool to discriminate moderate from severe AR among both treated and untreated patients.

Abstract
BACKGROUND This study was conducted to determine the impact of allergic rhinitis (AR) on health-related quality of life in patients in primary care. METHODS Observational, cross-sectional, multicentre study that included a national sample of patients consulting general practitioners for AR. Patients consulting for Hypertension were studied as a control sample. A general activities questionnaire, the mini Rhino conjunctivitis Quality of Life Questionnaire (mini-RQLQ) and the Medical Outcome Short-Form (SF-12) were employed. RESULTS A total of 133 general practitioners and 1,309 patients were included, 1,093 (83.56%) patients were diagnosed as AR and 215 (16.44) as Hypertensive. Adjustments were made for age and gender. The effect of AR on daily activities was noteworthy; the impairment in activities in relationship with sport, work, driving cars and entertainment was higher in AR than in patients with hypertension, with statistical differences. Both diseases, AR and hypertension, had a moderate impact on SF-36 physical and mental summary scores, without statistical significance. Adjusted sex and age were PCS12: (AR: 54.2+/- 19.30; hypertension 57.6 +/- 22.01, p=0.075) and MCS12:(AR: 56.9+/-19.70; hypertension 58.8 +/-19.82, p=0.330), without statistical significance. Patients with AR showed an impact in all domains of mini-RQLQ and the severity of disease according mini-RQLQ score had a good correlation with the impairment of daily activities. 76.7% of patients with AR had a coexistent atopic disease (asthma, conjunctivitis, atopic dermatitis) as well as a disease in relationship with rhinitis (sinusitis, upper and lower airway infections...). Asthma has been the disease more frequently associated to AR. CONCLUSION AR and hypertension had a moderate impact on health related quality of life. It was similar in both diseases. An epidemiological association between rhinitis and asthma has been established in patients consulting primary care doctors.

Abstract
BACKGROUND Allergic rhinitis is the most frequent chronic allergic disease in children, and may be an important risk factor for the subsequent development of asthma. OBJECTIVE To describe the characteristics of patients younger than 14 years of age presenting with rhinitis and the possible association with asthma. METHODS We carried out a prospective, observational, descriptive, cross-sectional epidemiologic study (Alergológica 2005) of 917 patients under the age of 14 consulting for the first time in allergy departments in Spain. RESULTS Rhinitis was diagnosed in 42.5% of the children. The association between asthma and rhinitis was significantly higher in children than in adults (44.9% vs 35.5%; P<.05). Time from onset of rhinitis was significantly associated with the development of asthma (2.97 vs 2.06 years; P<.0001). Allergy was the most frequent cause of rhinitis in children with and without asthma. Allergy to epithelia and fungi was more frequent in children with rhinitis and asthma than in children with rhinitis alone. We found no differences in the frequency of treatment with immunotherapy between children with and without asthma. CONCLUSION Rhinitis was frequently associated with asthma in children consulting for the first time at allergy departments. Time since onset of rhinitis and sensitivity to epithelia and fungi were associated with the development of asthma.

Abstract
BACKGROUND Allergic rhinitis (AR) is considered to be the most frequent allergic disorder. OBJECTIVE To present the data from the Alergológica-2005 on the characteristics of patients with AR. METHODS An observational, descriptive, cross-sectional epidemiologic study was performed on 4991 patients consulting for the first time in Allergology services in Spain. RESULTS Fifty-five percent of patients consulting Allergology services for the first time were diagnosed with AR, of whom 65% also had conjunctivitis and 37% asthma. Two out of every three subjects with AR consulted their primary care physician twice in the previous 4 months. One third was treated by another specialist in the preceding year and one of every five required treatment in emergency departments. AR affected the quality of life (SF-12), in some cases causing time off work and school. The most frequently involved allergens were pollens (51%), followed by dust mites (42%). Polysensitization was found in 31% of cases. Antihistamines and nasal topical corticoids were the most widely used drugs. In 38% of patients, treatment with specific immunotherapy was begun. CONCLUSIONS AR was the leading cause of consultations in Alergológica-2005. Rhinitis was frequently associated with other allergic disorders in 65% of patients with conjunctivitis and 37% with asthma. The illness led to a substantial use of healthcare resources and significantly affected the quality of life of the sufferers.

Abstract
The aim of this study was to determine the localization of calmodulin (CaM) in ram sperm and the possible changes during in vitro capacitation (CA) and the ionophore-induced acrosome reaction (AR). Likewise, changes in intracellular calcium levels ([Ca(2+)](i)) were also analysed by using flow cytometry. CA was induced in vitro in a medium containing BSA, CaCl(2), NaHCO(3), and AR by the addition of the calcium ionophore A23187. The acrosomal status was assessed by the chlortetracycline-fluorescence (CTC) assay. Flow cytometry (FC) analyses were performed by loading samples with Fluo-3 AM, that emits fluorescence at a high [Ca(2+)](i), combined with propidium iodide (PI) that allowed us to discriminate sperm with/without an integral plasma membrane both with high/low [Ca(2+)](i). Immunocytochemistry localized CaM to the flagellum, and some sperm also contained CaM in the head (equatorial and post-acrosomal regions). CA and AR resulted in a slight increase in the post-acrosomal labelling. The treatment of sperm with increasing concentrations of two CaM antagonists, W7 and calmidazolium (CZ), accounted for an increase in capacitated and acrosome-reacted CTC-sperm patterns. CZ induced a significant reduction in the content of three protein tyrosine-phosphorylated bands of approximately of 30, 40 and 45kDa. However, W7 showed no significant effect at any of the studied concentrations. Neither of them significantly influenced protein serine and threonine phosphorylation. FC analysis revealed that the main subpopulation in the control samples contained 70% of the total sperm with integral plasma membrane and a medium [Ca(2+)](i). After CA, 67.1% of the sperm preserved an integral membrane with a higher [Ca(2+)](i). After AR, only 7.2% of the total sperm preserved intact membranes with a very high [Ca(2+)](i). These results imply that CaM appears to be involved in ram sperm capacitation, and both treatments increased its localization in the post-acrosomal region.

Abstract
Certain features of capacitated or frozen-thawed spermatozoa have been considered to be an apoptosis-like phenomenon, and, it has been suggested that the presence of apoptotic sperm in seminal doses could be one of the reasons for poor fertility. The objective of this study was to determine whether phosphatidylserine (PS) translocation, caspase activity and DNA fragmentation, which are considered to be apoptotic markers in somatic cells, occur in ram sperm. Fresh ejaculates and sperm samples in different physiological state (cold-shocked, in vitro capacitated and acrosome-reacted (AR)) were compared. Simultaneous staining with 6-carboxifluorescein diacetate (6-CFDA) and Annexin V-Cy3.18 (AnnV) revealed four different sperm subpopulations in ejaculates. The main subpopulation was composed of viable cells without PS exposure (CFDA+/AnnV-). A total of 40.8% of sperm showed inverted PS, with two levels of alteration: CFDA+/AnnV+ in midpiece ("type I AnnV+"), and in acrosome and midpiece ("type II AnnV+"). The fewest subpopulation contained non-viable cells showing Annexin labelling in the entire cell (CFDA-/AnnV+). Labeling of caspases-3 and -7 by immunocytochemistry revealing different sperm subtypes depending on their localization in apical, equatorial, post-acrosomal regions and tail. The results obtained by western-blot showed, for the first time to our knowledge, that caspase-like proteins are present in fresh ram semen as both inactive and active forms. The proportion of sperm with fragmented DNA [terminal transferase-mediated dUDP nick end-labeling (TUNEL)-positive] were found rarely (2.7+/-0.5%) in all fresh ejaculates involved in this study. The analysis of total activity of both caspases by a fluorometric method showed a decrease in vitro capacitated and acrosome-reacted samples as well as in cryoinjured samples. However, the percentage of TUNEL-positive sperm demonstrating DNA fragmentation was significantly increased after in vitro induced capacitation and acrosome reaction, as well as after cold-shock although this augment was not significant. PS exposure is not totally dependent on caspases in ram spermatozoa as the addition of a caspase inhibitor prevented the increase in PS inversion due to incubation in capacitating conditions but not to the ionophore-induced acrosome reaction or cold-shock.

Abstract
BACKGROUND We compared the psychometric properties of the ESPRINT-15, the short form of a new Spanish instrument to measure health-related quality of life in allergic rhinitis (AR) patients, with those of the Mini-Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ). METHODS The questionnaires were compared in Spanish patients with intermittent allergic rhinitis (IAR) or persistent AR in a prospective, observational study. Floor and ceiling effects, internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficient; ICC), convergent and known groups validity, and sensitivity to change (standardized response means; SRMs) were compared. RESULTS In terms of content, while the MiniRQLQ has a dimension covering practical problems and places more emphasis on symptoms, the ESPRINT-15 has two dimensions (Sleep and Psychological impact) which are not included in the MiniRQLQ. In the validation study, 400 patients were included and 59% of the sample had persistent AR. There were no significant floor or ceiling effects on any dimension on either questionnaire. Cronbach's alpha values for the ESPRINT-15 and MiniRQLQ overall scores were 0.92 and 0.90, respectively. In 48 clinically stable patients, ICCs were 0.80 and 0.77, respectively. Both instruments discriminated between patients with IAR and persistent AR. Correlations with symptom scores and generic measures were moderate to strong. SRMs for overall scores and individual dimensions on the two questionnaires in the 197 patients reporting a change in health status ranged from 0.7 to 1.3. CONCLUSIONS Both questionnaires performed well in psychometric terms. The ESPRINT-15 is particularly recommended for use in Spanish-speaking populations.

Abstract
BACKGROUND Chenopodiaceae pollen is considered the main cause of pollen allergy in desert countries and its incidence is world-wide increasing by the desertization of extensive zones. Although the correlation between the sensitization to Chenopodium album and Salsola kali pollens of patients suffering from allergy to Chenopodiaceae pollens is high, a significant number of patients exhibited IgE sensitivity exclusively towards S. kali. OBJECTIVE To analyse this differential reactivity and to purify, clone and characterize the putative responsible allergen. METHODS Immunoblotting was used to analyse the IgE binding to pollen extract for S. kali and C. album. The protein was isolated by two chromatographic steps and characterized by Edman degradation, mass spectrometry, finger print analysis and Concanavalin A lectin staining. Specific cDNA was amplified by polymerase chain reaction, cloned in Escherichia coli and sequenced. Immunologic characterization was performed by immunoblotting, enzyme-linked immunoassay detection and inhibition experiments using sera from 11 patients allergic to S. kali pollen. RESULTS cDNA codifies for a mature protein of 339 amino acids plus a putative signal peptide of 23 residues and it belongs to the plant pectin methylesterase (PME) family. It is a mildly basic and polymorphic protein and was recognized by the IgE from all the patients allergic to S. kali included in the study, and was called Sal k 1. The protein was not recognized in the C. album pollen extract using the sera of these patients. CONCLUSION Sal k 1 is a protein from the PME family with a high allergenic relevance. Considering this allergen as responsible for the different sensitization between S. kali and C. album pollen, it may be a useful marker to classify patients allergic to Chenopodiaceae allowing a safer and more specific immunotherapy.

Abstract
BACKGROUND The objective of this study was to evaluate the effects of omalizumab on bronchoconstriction induced by methacholine and adenosine 5'-monophosphate (AMP). METHODS Thirty-four subjects with mild to moderate allergic asthma were randomized to receive placebo (n = 16) or omalizumab (n = 18) subcutaneously during 12 weeks. Airway responsiveness to AMP was measured at baseline and after 4 and 12 weeks of treatment, whereas the response to methacholine was measured at baseline and after 12 weeks of treatment. RESULTS After 4 weeks of treatment, the increase in AMP PC(20) (provocative concentration required to produce a 20% fall in FEV(1)) was significantly greater in the omalizumab group than in the placebo group, the mean difference in the change between the groups being 1.52 doubling concentrations (95% CI, 0.25-2.79, p = 0.02). Compared with baseline, the mean AMP PC(20) values at 12 weeks were increased by 1.91 doubling concentrations with omalizumab (p < 0.001) and 1.01 doubling concentrations with placebo (p = 0.16), but changes were not significantly different between the treatment groups. Changes in methacholine PC(20) values were not significantly different between the omalizumab and placebo groups. CONCLUSIONS In subjects with allergic asthma, omalizumab reduces the response to AMP without decreasing the response to methacholine. These findings are consistent with the conclusion that the contribution of IgE to the development of AMP bronchoconstriction is more important than their role in the induction of methacholine hyperresponsiveness.

Abstract
Autogenous breast reconstruction is frequently carried out with abdominal tissue, since a better and lasting aesthetic result is obtained, providing a new breast that is very similar in texture, consistency and ptosis to the contralateral breast. The main problem presented by this type of reconstruction is the sequel at the level of the donor abdominal area. Perforator flaps are being developed as the main resource for solving this problem, as they hardly damage the muscle and its fascia. The DIEP flap (deep inferior epigastric perforator) has proved itself to be an alternative for reconstruction for many women, with low rates of local complications, due to the absence of any sacrifice of the abdominis rectus muscle, and a significant level of satisfaction with the result obtained. One drawback is its greater technical difficulty and the need for a surgical team that is expert in vascular microsurgery. However, the DIEP flap is a surgical technique for which there is growing demand.

Abstract
Breast reconstruction with tissue expanders is a technique that has been known to clinical practice since 1978. The authors present their clinical experience in the Plastic and Reconstructive Surgery Service of the Virgen del Camino Hospital from 1980 to 2005. They describe breast reconstruction using tissue expanders and the evolution towards immediate breast reconstruction with durable expanders prostheses, which resemble conventional breast prostheses and try to emulate the extirpated breast. They provide an historical review of the repercussion of mastectomy and breast reconstructive surgery in the different professional and social areas, as well as the change in mentality of society and health professionals that has benefited patients. The characteristics of post-mastectomy breast reconstruction, using expanders prostheses, are set out, as well as its advantages and drawbacks.

Abstract
In breast reconstruction we try to achieve the greatest possible symmetry with the contralateral breast, with the smallest number of interventions, the least possible sequel and the greatest safety. When we find poor cutaneous quality in the thorax we must use techniques that provide a well vascularised tissue of good quality, which we obtain at a certain distance instead of using the thorax tissues themselves. This article reviews the latissimus dorsi musculocutaneous flap, the technique of elevation, variations of the flap, and the advantages and drawbacks involved. This is a very safe and versatile technique, with few sequels in the donor area, with a relatively short surgery time and with good aesthetic results.

Abstract
UNLABELLED We performed a prospective observational study to establish a relationship between pollen counts of Chenopodiacea/Amaranthacea and clinical symptoms of rhinoconjunctivitis and asthma in a group of monosensitised patients. MATERIAL AND METHODS A total of 60 patients (19 with asthma) were included in the study. All patients collected daily symptom scores during the summer months of 1999, 2000 and 2001. The questionnaire included ocular, nasal and pulmonary symptoms. Pollen counts were expressed as pollen grains/m3. Symptom scores and pollen counts were correlated using correlation coefficients and Log transformed variables. RESULTS In the 3 seasons studied we identified a peak of pollen and clinical symptoms in the second half of August and first half of September. In 1999, there was a significant positive correlation between total symptoms and daily pollen grains/m3 (p<0.005, r = 0.347). This correlation was not significant for the summers of 2000 and 2001. After further analysis, and by displacing one of both variables between 11 to 17 days, the correlation coefficients for total symptoms, improved for 1999 (r = 0. 744; p < 0.0001) and became significant for 2000 (r = 0. 521; p < 0.0001) and 2001 (r = 0.635; p < 0.0001). CONCLUSION We identified a significant time lag between pollen counts and symptom scores in S. kali monosensitized patients.

Abstract
BACKGROUND Salsola kali (Russian thistle) is a weed which belongs to the Chaenopodiacea family. It is widely distributed along the coasts of Europe, North Africa, USA and Australia. The objectives of this study were to study the allergenic composition of S. kali pollen and to purify an important allergen from the pollen extracts of this plant. METHODS A population of 66 individuals with specific IgE-mediated allergic symptoms and positive skin tests to S. kali were included in the study. Specific IgE to S. kali was determined by direct enzyme-linked immunosorbent assay (ELISA). The antigenic and allergenic profile of S. kali was evaluated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), isoelectric focussing (IEF) and immunoblot. Allergen purification was conducted by preparative SDS-PAGE. The allergenicity of the protein was evaluated by skin testing, direct ELISA, ELISA inhibition and immunoblots. RESULTS Specific IgE to S. kali was detected in 39 of the 66 individuals (59%). An allergen with a molecular weight of approximately 43 kDa was purified. This allergen was termed Sal k 1. A partial sequencing was obtained and no homology was found with other known proteins/allergens. The allergenicity of Sal k 1 was tested in vitro and in vivo. Of the 39 individuals with a positive specific IgE determination to S. kali, 26 (66.6%) had detectable specific IgE to Sal k 1. Twenty of these 39 individuals were skin-prick tested with the purified allergen (0.5 mg/ml) and all of them had a positive skin test to the purified allergen. Ten additional individuals, used as negative controls, had a negative response. CONCLUSIONS Sal k 1, an important allergen of S. kali, is recognized, in vitro, by approximately 67% of the patients sensitized to S. kali. Twenty patients with a positive skin test to a standardized S. kali extract had a positive reaction to the purified allergen.
