1–3 During pregnancy, congestion and other rhinitis symptoms can develop de novo during the second month of gestation and continue to term, but usually resolve shortly after delivery. Hormonal rhinitis can be caused by hormonal changes of pregnancy, menstrual cycle, puberty, or thyroid disorders. It has been proposed that NARES may be an early stage of aspirin sensitivity. 1–3 Nasal smears demonstrate eosinophils, but patients are not allergic to environmental allergens. Nonallergic rhinitis with eosinophilia syndrome (NARES) is characterized by perennial nasal symptoms and typically presents with prominent nasal congestion, sneezing paroxysms, profuse watery rhinorrhea, nasal pruritus, and occasional loss of smell. Such hyperreactivity to nonallergic triggers may also occur in AR, a clinical picture that is sometimes termed ‘mixed rhinitis.’ In recent years, computerized tomography (CT) has revealed that many patients diagnosed with VMR do in fact have chronic sinusitis or other disorders. The term VMR is sometimes used more selectively to indicate nasal symptoms that occur in response to nonallergic environmental stimuli, such as changes in temperature or relative humidity, perfumes, cleaning materials, tobacco smoke, alcohol ingestion and sexual arousal. Nasal obstruction and/or rhinorrhea are prominent symptoms, with sneezing and pruritus being less common. Nonallergic rhinitis without eosinophilia, variably termed vasomotor rhinitis (VMR) or idiopathic rhinitis, 1–3 is not caused by allergic or infectious processes, but is probably a heterogeneous group of disorders whose pathogenesis is incompletely understood. ![]() Symptoms of AR frequently overlap with symptoms associated with other forms of rhinitis and various anatomic abnormalities of the upper airway. 1 Postnasal drip occurs commonly, as do associated symptoms involving the ears, eyes, and throat. In addition to the four classic symptoms of AR (rhinorrhea, nasal congestion, sneezing, nasal itching), patients with AR commonly experience symptoms of conjunctivitis (eye pruritus, lacrimation, chemosis). Dykewicz, in Clinical Immunology (Third Edition), 2008 CLINICAL PRESENTATION OF DIFFERENT TYPES OF RHINITIS Food allergy in individuals with asthma may predispose them to more severe episodes and may be a risk factor for more severe and fatal asthma. ![]() However when a patient with asthma has symptoms that are not responding in the usual fashion to treatment, a food reaction should be considered and the treatment approach altered to include injected epinephrine. ![]() Asthma is infrequently the sole manifestation of an allergic reaction to food. It is important to note that a hacking staccato cough may be a sign of impending laryngeal obstruction without other symptoms and may lead to abrupt airway closure. In the lower respiratory tract, symptoms and signs include stridor, hoarse voice, cough, dyspnea and wheezing. Respiratory symptoms of a food allergic reaction include those in the upper respiratory tract – sneezing, nasal pruritus, rhinorrhea and congestion, and periocular pruritus and tearing.
