Objective: In patients with intermittent allergic rhinitis, allergen challenge may induce both early- and late-phase responses. The aim of this study was to examine the correlation between inflammatory cells in the nasal lavage fluid and clinical parameters following pollen challenge.
Material And Methods: Nasal lavage fluids were obtained from 29 patients with intermittent allergic rhinitis before and 1 and 6 h after allergen provocation, representing the control, early and late phases, respectively. Symptom and rhinoscopic scores were registered on the same occasions. Inflammatory cells were determined in the nasal fluid.
Results: The early phase was characterized by increased symptom scores, rhinoscopic signs of oedema and secretion and neutrophilia. In the late phase, symptom scores had diminished, but the signs of ongoing secretion remained. Both the total nasal symptom score and the secretion score correlated with the number of neutrophils in lavage fluids at 1 h. The eosinophil count did not increase during the early or late phases.
Conclusion: A single allergen provocation induces an early-phase response dominated by neutrophils, with secretion being the only clinical sign remaining during the late phase. The increase in neutrophil numbers correlated with the registration of secretory symptoms. The presented data indicate a role for neutrophils in intermittent allergic rhinitis and their relation with secretory parameters makes it intriguing to speculate that neutrophils may function as promoters of nasal secretion.

Although numerous studies have focused on diagnostic biomarkers to help identify allergic rhinitis (AR), data on the characteristics of pediatric AR with different severity is limited. We aimed to compare the characteristics of pediatric AR with different severity. A total of 1054 children with AR were enrolled and classified into mild intermittent AR, mild persistent AR, moderate-to-severe intermittent AR, and moderate-to-severe persistent AR.

Background And Objectives: The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines classify rhinitis as "intermittent" or "persistent" and "mild" or "moderate-severe". To assess ARIA classes in a real-world study in terms of phenotypic differences and their association with asthma.
Methods: We performed a cross-sectional real-world study based on users of the MASK-air® app who reported data for at least 3 different months.

Background: Uterine fibroid embolization can be associated with significant pain due to fibroid ischemia and interventions of the procedure itself. Fentanyl and midazolam are commonly provided for sedation and pain relief, but are not tolerated by all patients. This report outlines a novel pain management strategy for uterine fibroid embolization in a patient who could not receive either opioids or benzodiazepines.

Background And Objectives: This retrospective study, conducted at a single tertiary medical center, aimed to investigate the correlation between the severity of allergic rhinitis (AR) based on subjective symptoms and the severity assessed through laboratory data.
Methods: In total, 584 patients who were diagnosed with AR by a multiple-allergen simultaneous test were included. Patients were classified into four groups according to the Allergic Rhinitis and its Impact on Asthma (ARIA) classification guideline.
