Despite a substantial burden on individuals, society and health economies, AR remains under-diagnosed, under-estimated and under-treated. Main symptoms defining this IgE-dependent inflammation of nasal mucosa are: sneezing, itchy nose, rhinorrhoea and nasal congestion. Real-world data obtained by mobile technology offer new insights into AR phenotypes and therapy. Clinical management aims to relieve or control symptoms, resolve allergic inflammation, and potentially induce allergen tolerance, using allergen immunotherapy. Most cases of AR respond rather satisfied to pharmacotherapy. A very useful tool, especially recommended for everyday clinical practice, is VAS (visual analogue scale) which can help with: to assessing the intensity of AR symptoms as well as choosing the most optimal therapeutic option. Pharmacological treatment of the condition should be safe; effective and easy to administer as we treat patients with chronic condition, sometimes for a long time. Most frequently used treatment of AR include oral, intranasal or ocular antihistamines, intranasal corticosteroids or combined intranasal antihistamines and corticosteroids. Based on real-life clinical experience it can be concluded that a fixed combination of intranasal corticosteroid and intranasal antihistamines (mainly MP-AzeFlu) may be considered to be most beneficial, particularly in monotherapy and AR resistant to previous treatment.

We still have unmet patients needs and we are still looking for better therapeutic options in this area.

Oxidative stress (OS) has been suggested to be an important indicator of carcinogenesis in some tumors. Therefore, the aim of our study was to assess the state of OS in patients with selected benign and malignant parotid gland tumors. After final postoperative histological diagnosis of the tumor, patients were divided into the following groups i.e. pleomorphic adenoma 35 patients, Warthins tumor (WT) - 17 patients, mucoepidermoid carcinoma - 9 patients and 45 controls.

Patients who did not perform mastoidectomy were excluded. In patients, the ratios, localization of FCD, and association of facial canal dehiscence with cholesteatoma were researched. Association between FCD and closed-cavity tympanomastoidectomy, open-cavity tympanomastoidectomy, and radical mastoidectomy procedures, and also an association between FCD and primary or revision surgery was evaluated. ResultsFacial canal dehiscence was found in 8.4% of patients. The relationship between dehiscence and cholesteatoma was found significant (p<0.001).
