Leiomyomas are benign smooth-muscle tumors that are common in the alimentary tract, uterus, skin, and subcutaneous tissue. They are very uncommon in the upper respiratory tract and rare in the nasal cavity and paranasal sinuses. To the best of our knowledge, only 23 such cases have heretofore been published in the literature. We report 2 new cases of sinonasal leiomyoma that originated at different sites in the nasal cavity. We also discuss the various investigative and therapeutic modalities available.

As it is known, allergic rhinitis is one of the most pressing issues of modern rhinology. At present, special attention is directed to the study of the problem of year-round allergic rhinitis, since in recent years its incidence in economically developed countries has been steadily growing. Often the only complaint of patients is the constant stuffy nose with mucous discharge, so both patients and doctors often underestimate the importance of timely diagnosis and treatment of the disease. According to research, year-round allergic rhinitis can contribute to the development of pathology of the nasopharynx, middle ear and auditory tube, nasal cavity and paranasal sinuses, which often take on a chronic or recurrent form. The treatment proposed in the clinical recommendations, carried out in three main areas, does not always lead to persistent remission of the atopic process. This article covers the course of ENT diseases against the background of respiratory chlamydia and mycoplasmic intracellular infection. The problem of year-round allergic rhinitis associated with respiratory intracellular infection has not been elucidated to date, but the chronization of the process, long uncontrolled course, and the tendency to complications of this pathology of the upper respiratory tract may be related to it.

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

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.

The search for rational treatment of diseases of the nasal cavity and paranasal sinuses is due to the high incidence among the world's population. Despite the absolutely clear recommendations that would seem to greatly facilitate the choice and scope of therapy, it is extremely important to have a differentiated approach to each patient, depending on age, concomitant pathology, the nature of the course of the disease, the severity of clinical, primarily pain symptoms, and the presence of rhinogenic complications. Differential diagnosis of viral and bacterial acute rhinosinusitis (ARS) allows to avoid unreasonable prescription of antibiotics in the former case and choose therapy in such a way as to help relieve clinical symptoms, timely cure the disease and prevent complications. A systematic review of the literature was conducted with the analysis of scientific research data on the evaluation of the effectiveness of protargol or silver proteinate in the local treatment of upper respiratory tract diseases. A review of studies shows that silver proteinate has astringent, antiseptic and anti-inflammatory effects. The spectrum of antimicrobial action of silver is much wider than many antibiotics and sulfonamides. At the same time, pathogenic microflora is more sensitive to silver ions than non-pathogenic microflora. The analysis of the works also demonstrates the absence of adverse reactions when using this drug. The obtained data allow us to recommend preparations based on silver proteinate as a complex therapy for acute and chronic diseases of the nasal cavity and nasopharynx. The vasoconstrictive effect of protargol allows it to be used as an alternative to decongestants in order to avoid the development of drug-induced rhinitis and tachyphylaxis. Sialor® is a new, convenient, affordable, longer-shelf-life form of silver proteinate.

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.

Local mass transfer coefficients measured using the naphthalene sublimation technique in an acrylic cast model of the human upper respiratory tract are reported as the Sherwood numbers for the corresponding regions. A steady air flow rate of 12 L per min was used for all measurements. Values of the Sherwood number are seen to be highest in the nasal cavity and proximal nasopharynx while a minimum value occurs just downstream from the larynx. Local values of the Nusselt number obtained in the trachea and proximal nasal cavity assuming a complete heat and mass transfer analogy agree well with in-vivo physiological measurements. The mass transfer coefficients found can be incorporated into an analytical model of respiratory heat and water vapor transfer or into a model of pollutant gas uptake in the respiratory tract.

Histopathologic Findings

Extramedullary (extraosseous) plasmacytoma represents a rare disease that accounts for less 5% of plasma cell neoplasms. It commonly occurs in the upper respiratory tract, with 80% of cases involving the paranasal sinuses, nasopharynx, or nasal cavity. Plasmacytomas of the eyelid are very rare with only ten cases having been reported in the literature so far. We present the clinical and histopathologic findings from a case of plasmacytoma of the eyelid and discuss its histopathologic differential diagnoses. To our knowledge, this is the first case of plasmacytoma of the eyelid in an HIV-positive patient in the English literature

Pigs reared in intensive production systems are continuously exposed to ammonia released by the microbial degradation of their excrement. Exposure to this gas has been shown to increase the severity of the disease progressive atrophic rhinitis by facilitating colonization of the pig’s upper respiratory tract by Pasteurella multocida. The etiological mechanism responsible for this synergy was investigated by studying the colonization kinetics of P. multocida enhanced by ammonia and comparing them with those evoked by an established disease model. Three-week-old Large White piglets were weaned and allocated to five experimental groups (groups A to E). Pigs in groups A and B were exposed continuously to ammonia at 20 ppm for the first 2 weeks of the study. Pigs in group C were pretreated with 0.5 ml of 1% acetic acid per nostril on days −2 and −1 of the study. On day 0 all the pigs in groups A, C, and D were inoculated with 1.4 × 108 toxigenic P. multocida organisms given by the intranasal route. The kinetics of P. multocida colonization were established by testing samples obtained at weekly intervals throughout the study. The study was terminated on day 37, and the extent of turbinate atrophy was determined by using a morphometric index. The results of the study showed that exposure to aerial ammonia for a limited period had a marked effect on the colonization of toxigenic P. multocidain the nasal cavities of pigs, which resulted in the almost total exclusion of commensal flora. In contrast, ammonia had only a limited effect on P. multocida colonization at the tonsil. The exacerbation of P. multocida colonization by ammonia was restricted to the period of ammonia exposure, and the number ofP. multocida organisms colonizing the upper respiratory tract declined rapidly upon the cessation of exposure to ammonia. During the exposure period, the ammonia levels in mucus recovered from the nasal cavity and tonsil were found to be 7- and 3.5-fold higher, respectively, than the levels in samples taken from unexposed controls. Acetic acid pretreatment also induced marked colonization of the nasal cavity which, in contrast to that induced by ammonia, persisted throughout the time course of the study. Furthermore, acetic acid pretreatment induced marked but transient colonization of the tonsil. These findings suggest that the synergistic effect of ammonia acts through an etiological mechanism different from that evoked by acetic acid pretreatment. A strong correlation was found between the numbers of P. multocida organisms isolated from the nasal cavity and the severity of clinical lesions, as determined by using a morphometric index. The data presented in the paper highlight the potential importance of ammonia as an exacerbating factor in respiratory disease of intensively reared livestock.
