The study analyzed the functional parameters of nasal breathing, linear parameters of the nasal aperture, nasal cavity and nasopharynx, volumetric parameters of the upper airways in patients with II and III skeletal class of jaw anomalies before and after orthognathic surgery. The respiratory function of the nose was assessed using a rhinomanometric complex. According to rhinoresistometry data, nasal resistance and hydraulic diameter were assessed. According to the data of acoustic rhinometry, the minimum cross-sectional area along the internal valve, the minimum cross-sectional area on the head of the inferior turbinate and nasal septum and related parameters were estimated. According to the CBCT data, the state of the nasal septum, the inferior turbinates, the nasal aperture, the state of the nasal cavity, and the linear values of the upper respiratory tract (nasopharynx) were analyzed. The patients were divided into 4 groups according to the classification of the patency of the nasal passages by

The Breathe Right nasal strips are more and more commonly used, mainly by athletes, who hope to enhance their physical performance in competition and training. The effect of the device in such situations is uncertain and perhaps somewhat controversial. To investigate the effects of the nasal strips on nasal ventilation, 20 Caucasian individuals were objectively assessed using anterior rhinomanometry and acoustic rhinometry. The results showed a significant increase in all subjects of transnasal airflow and in the average cross-sectional area of the nasal cavity that quantifies objectively the subjective impression of improved nasal breathing. In such patients where an improvement in nasal ventilation is desired, the use of the Breathe Right nasal strips seems to offer a beneficial treatment.

The project "Implementation of rapid prototyping for modelling the upper respiratory tract in normal and typical pathologies" investigates the urgent problem of improving the reliability of diagnosis and effectiveness of treatment of disorders of the nasal breathing. Possibilities of modern 3D-printing technology for creation of individual natural anatomical models of the upper respiratory tract and determination of their aerodynamic characteristics are considered. The characteristics of the laminar boundary layer of the air flow in the parietal region of the nasal cavity are investigated under different modes of breathing in normal and with typical disorders of the nasal breathing. The concept of investigation of the aerodynamic indices of the anatomical structures of the respiratory system by the results of test tests of individual full-scale 3D models, obtained by the data of spiral computed tomography, is being developed. Theoretical bases of the method of computer planning of restorative rhinosurgical interventions in patients with chronic diseases of the nasal cavity are grounded, based on the change of the configuration of the anatomical structures of the nasal cavity taking into account the aerodynamic parameters of respiration. Modern distance learning and testing tools are being created to demonstrate the technology developed, to provide theoretical knowledge, practical skills and to solve situational tasks for a wide range of specialists. Development and research of natural patterns of the upper respiratory tract allows for supplementing and expanding the knowledge about the aerodynamic characteristics of the nasal cavity, to make decisions about therapy in a short period of time. Experience of the Laboratory of the Institute for Multiphase Processes (IMP) of the Leibniz Universität Hannover (LUH) in the development and use of rapid prototyping capabilities in biotechnology will provide technical support to the project.

We investigated the effects of antigen and histamine on the nasal passage patency in guinea pigs with or without nasal allergy. The change of nasal patency was measured by acoustic rhinometry and nasal airway resistance. Acoustic reflections have been used in adult humans to determine nasal cavity dimensions in terms of cross-sectional areas as a function of the distance from the nostril. In order to measure nasal cavity dimensions in guinea pigs, we modified equipment for use in humans by decreasing sound tube dimensions, increasing sampling frequency, and applying a special nosepiece. The percent change of volume, minimum cross-sectional area, and nasal airway resistance showed the largest changes at 10 minutes after antigen challenge in sensitized guinea pigs. There was a significant correlation between the individual percent change of nasal airway resistance and volume or minimum cross-sectional area. Histamine, 102 to 105 μg/mL, caused a dose-dependent reduction in percent change of volume in the challenged side of nonsensitized guinea pigs, but not in the opposite side. These results indicate that the noninvasive acoustic reflections technique is useful in small experimental animals, especially to assess the effect of nasal cavity dimensions after the challenge of antigen or nonspecific stimuli.

Upper respiratory tract infections (URTI) are a large group of infectious diseases (mainly viral and bacterial), affecting the mucous of the nasal cavity, paranasal sinuses, pharynx and larynx. URTI are very common in inpatient and outpatient clinical practice. In this article, we present a clinical case of Patient N., 20 years old, consulted with upper respiratory tract damage caused by Chlamydia pneumoniae. The patient admitted to clinical diagnostic center on 07.07.2021 with complaints of pain in the left maxillary sinus with irradiation to the left temporal region, difficulty in nasal breathing, pain in the pharynx, aggravated by swallowing, and increased body temperature (37,5 °C). The patient was consulted by an interdisciplinary team (ENT doctor and clinical pharmacologist). After carrying out physical, instrumental and laboratory tests the diagnose Chlamydia pneumoniae - associated URTI was established and, the patient was prescribed doxycycline at a dose of 100 mg 2 two times a day on the 1st day following by 100 once a day for the next 6 days with a positive effect. The doxycycline was choisen because of a more favorable safety and efficacy profile compared to fluoroquinolones and some other antibacterial agents. After 7 days of treatment, the patient recovered completely. Among all doxycycline drugs available on the market of the Russian Federation, Doxycycline Express (JSC Pharmstandard-Leksredstva) stands out due to its high quality, bioequivalence to the original drug and comfortable regime of use due to the dosage form (dispersible tablets), that increases the patient’s compliance and allows it to be used by some special categories of patients (elderly and senile patients, patients with dysphagia, etc.

SummaryDocumentation of normal and pathological anatomy is important to all medical practitioners. The ability to visualize and photograph the upper respiratory tract has been revolutionized by the advent of the flexible fibreoptic rhinolaryngoscope (FFRL), which demonstrates a one-instrument capability for the examination and photodocumentation of the ears, nasal cavity, nasopharynx, larynx, hypopharynx and trachea (Selkin, 1984). If a large natural maxillary ostium, or surgical window, is present, the antrum may also be examined.

Background: Upper respiratory tract infections are one of the leading causes of hospital visits worldwide. Judicious use of antibiotics is challenging for upper respiratory tract infections (URTIs) in developing countries like India. This leads to inappropriate use of antibiotics causing many dreaded conditions like antibacterial resistance among other things. Hence rational use of drugs, mainly antibacterial, is a priority to reduce the burden of treatment failure. The objective of this study is to study the prescribing patterns and rationality of drugs prescribed in the management of URTIs.Methods: This was a cross-sectional study. Data was collected from records of 300 outpatients clinically diagnosed as URTIs from SSIMS and RC Hospital, Davangere between January 2015 and June 2016. The prescribing patterns, approval status and listing of drugs in World Health Organization (WHO) essential medicines list/ National List of Essential Medicines (NLEM) were analysed. The data was presented as percentages, mean and standard deviations.Results: A total of 300 cases were studied. Among these, acute pharyngitis (29%) and acute sinusitis (26%) are the most common infections. Of the 300 cases studied, 283 (94.3%) were prescribed antimicrobials. Of the total 740 medications prescribed, 393 (53.1%) were fixed-dose combinations (FDCs). A total of 724 medications (97.8%) were approved by Drugs Controller General of India and 248 (33.5%) by Food and Drug Administration. Only 5.8% of the prescribed drugs have been listed in WHO’s and NLEM. The most common class of antibacterials prescribed was Beta-lactams.Conclusions: Oral formulations were preferred over parenteral formulations and FDCs were preferred over single drug formulations. Beta-lactams comprised the major class of antibacterial prescribed.

It has long been known, that nasal saline irrigation is a safe and effective method, which is routinely prescribed by otorhinolaryngologists to prevent and to treat a wide range of pathologies. There are a lot of publications on different irrigation techniques and methods. This literature review discusses the key parameters of nasal irrigation, including tonicity, pH, and the additional components, and explains how they affect the effectiveness of the procedure. The vast majority of available publications did not found any possible changes in the effectiveness of solutions with different pH close to neutral meaning. Whereas, the volume of the irrigated solution, increases the efficiency of the irrigation in direct proportion. Thus, the largest distribution area of the solute is noted when washing with a large volume of liquid. Nasal saline irrigation is an effective treatment option for patients with several acute and chronic diseases and for postoperative care after rhinosurgery. Moreover, nasal irrigation might be used as an effective non-specific method for prevention of acute upper respiratory tract infections. Irrigation of the nasal cavity reduces the mucus viscosity and promotes its faster elimination, along with pathogens fixed in it. Additionally, irrigation with isotonic saline solutions increases the hydration of the underlying water base, which enhances the frequency of ciliary beat and reduces the concentration of local inflammatory mediators. COVID-19 pandemic situation due to lack of any specific antiviral drugs dictates the necessity of an effective non-specific preventive option, which could be introduced worldwide. The so-called full volume lavage of the nasal cavity allows for better cleaning of the nasal cavity and effective moisturizing of the mucous membrane. It is the timely cleansing and moisturizing that are most important for maintaining the normal activity of the local protective mechanisms of the upper respiratory tract.
