While their clinical presentation is similar, post-viral rhinosinusitis does not indicate the possible development of bacterial rhinosinusitis which occurs in only 0.5% to 5% of all cases of ARS. However, unreasonable antibacterial therapy is prescribed in 54% to 77% of cases. The perspective is to use delayed antibacterial therapy management. The purpose of the study was to investigate the efficacy of mometasone furoate nasal spray within the delayed prescription approach. Methods: A multicenter, randomized, open-label, comparative, prospective, parallel group study enrolled a total of 156 patients with ARS aged 18 to 60 years, of them 155 patients completed the study. The patients were randomized into the main group of Mometasone Furoate (Flix) Nasal Spray or into the control group of amoxicillin clavulanate tablets while both groups were administered a standard ARS therapy. Findings: The use of MF nasal spray within the delayed antibiotics prescription approach has a significantly higher efficacy compared to the immediate antibiotics prescription in the first days of treatment (p y was prescribed to 42.3% of patients in the main group compared to 100.0% of patients in the control group (p y significant differences in the dynamics of changes in the total symptom score between the patients administered antibiotics and the antibiotic-naive patients. Conclusion: The use of MF within the delayed antibiotics prescription approach reliably improves the pattern of symptoms over time at the disease onset and significantly reduces the need for NSAIDs administration and antibiotics prescription frequency.

New methods of an automated evaluation of the blood rheological parameters: 1) the viscosity, 2) electric conductivity and 3) the charge of erythrocytes have been theoretically and experimentally substantiated by way of registering the Q-factor of the tuned-circuit, containing a capillary with the blood flow. A design of an electronic measuring complex is based on modeling the physical blood conditions in the natural environment.

The characteristics, performance and application of membrane sensors based on ion-pair Brilliant Green mefenamate are described. The sensor＇s response to the mefenamate ion has the sensitivity of （86.0 ± 2.0） mV/pC over the range of 9 × 10 s-I × 10 2 mol/L and the detection limit of 4.5 ×10 s mol/L at pH 8.5-12. The sensor is easily assembled at a relatively low cost and has fast response time （5-10 s）. The proposed sensor displayed good selectivity for mefenamate ion in the presence of different substances. It was used to determine mefenamic acid in pharmaceuticals.
