Abstract
Data about allergic sensitization to rhinitis among adults are limited. The objectives were to explore the prevalence of current rhinitis (CR) and associated specific allergen sensitizations in southwestern Saudi Arabia. A cross-sectional study was conducted on 969 adults in southwestern regions of Saudi Arabia, namely Aseer, Jazan, and Al Baha. From each region, 5 primary health care centers were chosen. The validated Arabic Version of the International Study of Asthma and Allergies in Childhood questionnaire was used. Total immunoglobulin E (IgE) enzyme-linked immunosorbent assay, cytokine enzyme-linked immunosorbent assay (interleukin [IL]-4, IL-10, IL-13, and interferon-γ), aeroallergen-specific IgE immunoassay (a panel of 30 common aeroallergens; 9 indoor and 21 outdoors), and eosinophilic count were assessed. A prevalence of CR of 35.8% (95% confidence interval: 32.8%-38.9%) was found. Regarding outdoor aeroallergens, Mesquite-positive IgE antibodies were higher among CR adults (odds ratio = 1.52, 95% confidence interval: 1.02-2.21) compared to those without CR. The same significant pattern was found with Chenopodium, Ragweed, Pigweed, Russian thistle, Bermuda grass, Timothy grass, and Rye. All indoor aeroallergens were not significantly associated with CR. Total IgE and eosinophil count were significantly higher among adults with CR. In conclusion, CR in southwestern regions of Saudi Arabia is common and of significant public health importance. Aeroallergens that associate with adult sensitization to CR tend to be of the outdoor variety particularly the herbaceous grass and their pollens. The magnitude of CR and its association with exposure to outdoor aeroallergens should be taken into account by health policy decision makers, clinicians, and medical practitioners when diagnosing and treating related conditions.

Abstract
Allergic airway diseases, with incidence augmenting visibly as industrial development and environmental degradation, are characterized by sneezing, itching, wheezing, chest tightness, airway obstruction, and hyperresponsiveness. Current medical modalities attempt to combat these symptoms mostly by small molecule chemotherapeutants, such as corticosteroids, antihistamines, etc., via intranasal approach which is one of the most noninvasive, rapid-absorbed, and patient-friendly routes. Nevertheless, inherent defects for irritation to respiratory mucosa, drug inactivation and degradation, and rapid drug dispersal to off-target sites are inevitable. Lately, intratracheal micro/nano therapeutic systems are emerging as innovative alternatives for airway allergy interventions. This overview introduces several potential application directions of mic/nano-platform in the treatment of airway allergic diseases, including carriers, therapeutic agents, and immunomodulators. The improvement of the existing drug therapy of respiratory allergy management by micro/nano-platform is described in detail. The challenges of the micro/nano-platform nasal approach in the treatment of airway allergy are summarized and the development of micro/nano-platform is also prospected. Although still a burgeoning area, micro/nano therapeutic systems are gradually turning to be realistic orientations as crucial future alternative therapeutic options in allergic airway inflammation interventions.

Abstract
Allergy, IgE-mediated inflammatory disorders including allergic rhinitis, asthma, and conjunctivitis, affects billions of people worldwide. Conventional means of allergy management include allergen avoidance, pharmacotherapy, and emerging therapies. Among them, chemotherapeutant intake via oral, intravenous, and intranasal routes is always the most common mean. Although current pharmacotherapy exhibit splendid anti-allergic effects, short in situ retention, low bioavailability, and systemic side effects are inevitable. Nowadays, nanoplatforms have provided alternative therapeutic options to obviate the existing weakness via enhancing the solubility of hydrophobic therapeutic agents, achieving in situ drug accumulation, exhibiting controlled and long-time drug release at lesion areas, and providing multi-functional therapeutic strategies. Herein, we highlight the clinical therapeutic strategies and deal with characteristics of the nanoplatform design in allergy interventions via intratracheal, gastrointestinal, intravenous, and ocular paths. The promising therapeutic utilization in a variety of allergic disorders is discussed, and recent perspectives on the feasible advances of nanoplatforms in allergy management are also exploited.

Abstract
The effect of α2-selective adrenoreceptor activation on nasal cavity dimension in an experimental model of congestion has not been defined. Presently, we used acoustic rhinometry to evaluate the decongestant activity of BHT-920, a selective α2-adrenergic agonist against nasal congestion produced by intranasal compound 48/80. Administration of the mast cell liberator compound 48/80 (1%) into a nasal passageway decreased ipsilateral volume and minimum cross-sectional area by 73 ± 4% and 42 ± 6%, respectively. The congestant effect of compound 48/80 was blocked by topical BHT-920 (0.3 and 1%) in a dose related manner. In addition, the decrease in minimum cross-sectional area produced by compound 48/80 was attenuated after topical BHT-920 treatment. As a comparison we also evaluated the topical decongestant activity effects of the α1-adrenergic agonist phenylephrine, and the nonselective α-agonist oxymetazoline. Both phenylephrine (0.1–1.0%) and oxymetazoline (0.01–0.3%) produced decongestion. The blood pressure effects of these three drugs also were evaluated. At doses of 0.3 and 1.0%, BHT-920 did not produce hypertension. In contrast, oxymetazoline (0.01–0.1%) produced a transient hypertension that peaked at 15 minutes and fully recovered 45 minutes after administration. The hypertensive effect of phenylephrine at 0.3 and 1.0% lasted over 60 minutes. The present findings indicate that selective α2-agonists may produce decongestant activity with an improved cardiovascular profile compared with current sympathomimetic drugs such as phenylephrine.

Abstract
BACKGROUND Chronic inflammatory airway disorders have been reported to be associated with vascular diseases of the heart and central nervous system, but their association with peripheral arterial disease (PAD), a high-prevalence vascular illness, has not been investigated. OBJECTIVE To evaluate the association of asthma and rhinitis with intermittent claudication, which is a typical symptom of PAD. METHODS The data were collected in the gene-environment interaction in respiratory disease survey, a population-based, multicase-control study. Participants underwent a standardized interview, skin prick tests and pulmonary function tests. The associations between respiratory diseases and intermittent claudication (i.e. pain in the leg during walking that disappears within 10 min when standing still) were estimated through relative risk ratios (RRR) by multinomial logistic regression models. RESULTS 1174 subjects (aged 20-64 years, of which 52% were females) underwent clinical examinations and were classified into four groups: asthma only (n = 81), asthma-rhinitis overlap (n = 292), rhinitis only (n = 299) and controls (n = 345). The prevalence of intermittent claudication in these groups was, respectively, 2.5%, 3.4%, 6.4% and 2.3%. After adjusting for smoking habits and a wide range of established and potential vascular risk factors, rhinitis without asthma was associated with intermittent claudication (RRR:4.63, 95% CI:1.72-12.5), whereas no significant association was found with asthma alone (RRR:1.45, 95% CI:0.27-7.76) or asthma-rhinitis overlap (RRR:2.89, 95% CI:0.91-9.18). Atopy did not modify the observed association between intermittent claudication and rhinitis. CONCLUSIONS Our findings suggest that rhinitis is associated with PAD, a predictor of future cerebrovascular and cardiovascular events, independently of the presence of atopy.

Abstract
The nose and lung are both part of the respiratory tract. Often the diseases affecting the nose and/or the bronchi are treated separately. However, in recent years, numerous studies have highlighted the fact that the respiratory system is a single entity and the concept of "united airway disease" has become more and more important. The unity of the respiratory tract is confirmed both from a morphological and from a functional point of view. Nevertheless, this concept is also confirmed for the respiratory immune system, innervation and vascularization interesting all along the tract, from the nose to the bronchioles. When treating rhinitis, it is often necessary to assess the presence of asthma. Patients with sinusitis should be evaluated for a possible concomitant asthma. Conversely, patients with asthma should always be evaluated for possible nasal disease. The medications that treat nasal diseases appear to be useful in improving control of asthma and in reducing bronchial hyperresponsiveness as well. Physicians should always keep these notions in mind, and evaluate and treat respiratory diseases taking into account the unity of the respiratory tract.

Abstract
Allergic diseases are common in athletes. As such, sports medicine practitioners will be involved in the management of allergic diseases on a nearly daily basis. Appreciating the wide array of allergic manifestations in this active population is essential to their accurate and efficient treatment. Although the bulk of allergic disease in athletes is mild, some allergic manifestations are far more serious and even potentially life-threatening. Aggressive and thoughtful allergy management should ensure that all athletes can continue to compete safely and at the highest level possible.

Abstract
BACKGROUND Antihistamines are the most commonly prescribed class of medication for perennial allergic rhinitis (PAR). The primary objective of this study was to determine whether levocetirizine (Xyzal(R)), the active enantiomer of cetirizine, could achieve at least a 50% improvement in PAR symptoms compared to the placebo over the first week of treatment. METHODS A total of 294 patients with PAR due to house dust mites were randomized in this 8-week double-blind, placebo-controlled, multicentre trial to receive either levocetirizine 5 mg/day or placebo. Mean Total Four-Symptom Scores (T4SS) (nasal pruritus, ocular pruritus, rhinorrhoea and sneezing) were compared between treatment groups over weeks 1, 4 and 6. All individual symptom scores, including nasal congestion, were also studied. RESULTS Levocetirizine showed an 86% improvement in T4SS over the first week of treatment and a 47% improvement over the entire treatment period compared with placebo. Absolute changes from baseline were 3.64 and 2.47 for levocetirizine and placebo, respectively. Individual symptom scores showed statistically significant (P < or = 0.01) differences in favour of levocetirizine for all study time-points. Nasal congestion was unexpectedly significantly improved (P < 0.001). The incidence of reported adverse events was comparable between treatment and placebo group. CONCLUSIONS Levocetirizine 5 mg/day is an effective and well-tolerated treatment of PAR. In addition, levocetirizine is effective for the relief of nasal congestion.

Abstract
The prevalence and differential diagnosis of rhinitis changes as we progress from birth to senescence. The heavy burden of allergic rhinitis is often overlooked in infants and disregarded in childhood and adolescence. In women, especially during pregnancy, hormonal changes can significantly affect nasal mucosal hyperreactivity and worsen ongoing syndromes. Various types of inflammatory and noninflammatory nonallergic rhinitides become more prevalent in the fifth decade and beyond. The burgeoning elderly population with irritant, atrophic, and medication-related rhinitis will constitute a greater proportion of our practices as the general population ages.
