Definition ARS is an inflammatory process of the nasal mucosa of sudden onset, lasting up to 12 weeks. Toll-like receptor 2 gene polymorphisms in a Korean population: association with chronic rhinosinusitis.

It may occur one or more times in a given period of time, but always with complete remission of signs and symptoms between episodes.

Nonetheless, in the pediatric population, cough is considered one of the four cardinal symptoms, replacing olfaction disorders. Nasal obstruction is one of the important symptoms of ARS and should be assessed together with other patient complaints.

when studying the symptoms of spontaneous rhinosinusal infections by rhinovirus in relation to the time of onset and duration, observed that the peak of typical symptoms such as nasal obstruction, rhinorrhea, and cough occurs between the second and third days of infection (Fig. In spite of the scarcity with which methods of objective evaluation of nasal obstruction (such as rhinomanometry, nasal peak inspiratory flow, and acoustic rhinometry) are applied in daily practice in patients with ARS, studies have shown a good correlation between the symptoms reported by patients and the objective measurements obtained by these methods.

A study by Principi and Esposito Concomitant chronic disease Concomitant chronic disease (bronchitis, asthma, cardiovascular disease, diabetes mellitus, or malignant tumor) in children has been associated with an increased incidence of ARS after Signs and symptoms At primary health care levels and for epidemiological purposes, ARS can be diagnosed based on symptoms alone, without detailed otorhinolaryngological assessment and/or without imaging studies. Nasal and paranasal sinus endoscopy, computed tomography and microbiology of upper airways and the correlations with genotype and severity of cystic fibrosis.

In these cases, the distinction between the types of ARS is mainly determined through clinical history and physical examination performed by general practitioners and specialists, whether or not otorhinolaryngologists. Polymorphism between loci for human leukocyte antigens DR and DQ in patients with nasal polyps.

It is worth mentioning that, at the time of the examination, patients may not report symptom worsening if not asked carefully.

The report of symptoms occurring a few days before with a recurrence of symptoms just before evaluation is frequent. Ramírez-Anguiano J, Yamamoto-Furuho JK, Barquera R, Beltrán O, Granados J.

The complaint of dental pain in the upper teeth abutting on the maxillary sinus showed a statistically significant association with the presence of positive bacterial culture obtained from sinus aspirates, with a predominance of the presence of two or more findings (purulent rhinorrhea and unilaterally predominant local pain, pus in the nasal cavity, and bilateral purulent rhinorrhea) showed 95% sensitivity and 77% specificity for the diagnosis of ABRS. It includes the loss of cilia and ciliated cells, as well as alteration of the normal mucociliary transport. Mutation in the gene responsible for cystic fibrosis and predisposition to chronic rhinosinusitis in the general population. However, smoking and allergies have also been implicated in the alteration of the mucociliary transport, Primary ciliary dyskinesia (PCD) This is a rare autosomal recessive disease, in which the cilia are either immotile or beat with a pattern incompatible with mucus transport in the airway. Increased prevalence of chronic rhinosinusitis in carriers of a cystic fibrosis mutation. The clinical examination of a patient with ARS should initially comprise assessment of vital signs and physical examination of the head and neck, with special attention aimed at the presence of localized or diffuse facial edema. At oroscopy, posterior purulent oropharyngeal secretions are important. Delagrand A, Gilbert-Dussardier B, Burg S, Allano G, Gohler-Desmonts C, Lebreton JP, et al.

Purulent rhinorrhea with unilateral predominance and pus in the nasal cavity have a positive predictive value of only 50% and 17%, respectively, for positive bacterial culture obtained by maxillary sinus aspirate.
