[Peak nasal inspiratory flow in the assessment of nasal airway obstruction].

Relevance: Nasal congestion is one of the most common complaints in otolaryngology practice and can significantly impact the quality of life for patients. Objective and subjective assessments provide different information, but objective assessment of nasal obstruction is crucial for accurate diagnosis and appropriate treatment. This review demonstrates that peak nasal inspiratory flow (PNIF) is a reproducible and reliable measure of objective nasal patency.

[Clinical and diagnostic features in the phenotyping of isolated sphenoiditis].

Unlabelled: The relevance of the issues of diagnosis and treatment of isolated sphenoiditis (IS) is increasing, due to the widespread introduction into clinical practice of radiation diagnostic methods that allow the diagnosis, including latent forms of IS. Among the chronic forms of IS, polypous-cystic and fungal lesions of the sphenoid sinus (SS) predominate.

Objective: To study the age, gender and radiological features of SS in patients with IS.

Periostin as a Biomarker of Allergic Inflammation in Atopic Bronchial Asthma and Allergic Rhinitis (a Pilot Study).

Unlabelled: The involvement of periostin in Th2-dependent allergic inflammation has been documented. However, the significance of periostin as a biomarker of local allergic inflammation in the nasal mucosa (NM) of patients with atopic bronchial asthma (BA) and allergic rhinitis (AR) is yet to be determined. was to determine the presence of periostin and evaluate its role as a non-invasive marker of allergic inflammation in the nasal secretions of children with atopic BA and AR.

The Relationship Between Indicators of Nasal Respiratory Function and Spirometric Parameters in Children With Bronchial Asthma.

The relationship between objective indicators of nasal obstruction and airflow limitation in children with bronchial asthma (BA) and allergic rhinitis (AR) has not yet been studied. To study the relationship between objective parameters of nasal obstruction and airflow limitation, determined using the methods of anterior active rhinomanometry (AARM) and spirometry in children with BA and AR. Eighty eight children and adolescents with BA and AR, boys-65.
