ABSTRACT The lesion of middle ear as a variant of clinical manifestation of secondary tuberculosis, according to international scientific literature, is a rare condition. However, in terms of real clinical practice, the proportion of this pathology should not be underestimated due to the wide spread of tuberculosis infection among the population of developing countries, including the Russian Federation. One of the risk factors for the systemic spread of mycobacterial flora is a concomitant HIV infection, which often acts as an opportunistic pathological agent for tuberculosis. The treatment of such a state is always challenging because of the high aggressiveness of bacteria and the low immunological resistance of the patient. This article presents a clinical case of bilateral tuberculosis otitis media, which was a manifestation of tuberculosis infection that dev eloped on the background of HIV infection.

The association between aeroallergenic structures and allergic rhinitis: a study on northern Vietnam

xlomafota13 shared this article with you from Inoreader The association between aeroallergenic structures and allergic rhinitis: a study on northern Vietnam Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(1):51-57. doi: 10.17116/otorino20218601151. ABSTRACT Recently, there has been an increase in the number of patients with allergic rhinitis (AR) and the number of publications devoted to this problem is increasing. The main etiological factors of AR are pollen of trees, meadow and weeds, as well as mold spores, household allergens and epidermis of animals. Epidemiological studies have found that the prevalence and structure of AR are influenced by regional characteristics, such as the climatic and geographical and social characteristics of the region, and successively therapeutic and preventive algorithms in AR are also different. AIM: To examine the phenotype of the incidence of AR in connection with the characteristics of aeroallergens under the influence of climatic and geographical conditions in northern Vietnam, to make a new contribution to knowledge about AR in Asia and to increase the effect of treatment and prevention in this territory. MATERIALS AND RESEARCH METHODS: The study was conducted in the period from 06.2018 to 09.2018 on the basis of the ENT department of Thainguyen Central Hospital, Vietnam. A total of 556 patients with pathology of ENT organs aged 18 to 70 years were examined, 158 cases of chronic rhinitis were revealed. Among data from 158 patients, 64 patients were diagnosed with AR. We used otorhinolaryngological examination, a standard specific allergological examination and carried out aeropolyneological research in the city of the northern Vietnam, from 06.2018 to 06.2019. RESULT: The aerobiological spectrum is dominated by pollen from the families Moraceae, Urticaceae, Poaceae, Acacia, Artemisia, fern spores and fungal spores from the genus Alternaria. Among patients with chronic rhinitis, 40% were diagnosed with AR, 98.44% of them year-round or perennial AR, with predominant sensitization to house dust mites and molds, much more often t o plant pollen. Among 9 (14.06%) patients diagnosed with a polyp of the nasal cavity, 6 (9.37%) patients had increased levels of specific IgE in the blood to a mixture of molds. Sensitization in patients with AR with hypertrophy of the mucous membrane of the nasal cavity is predominant on house dust. CONCLUSION: Predominantly, AR in northern Vietnam was year-round. Especially the connection between the formation of a polyp of the nasal cavity and hypersensitivity to fungal spores has been indicated, which may also indicate the role of social factors in further recommendations for the diagnosis, treatment and prevention of AR in patients living in North Vietnam.

Psychoacoustic tests for perceptual assessment of processor fitting in patients with cochlear implants

xlomafota13 shared this article with you from Inoreader Psychoacoustic tests for perceptual assessment of processor fitting in patients with cochlear implants Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(1):30-35. doi: 10.17116/otorino20218601130. ABSTRACT THE AIM OF THE STUDY: Was to study the possibility of using a battery of psychoacoustic tests to assess the tuning of the cochlear implant processor (CI) in deaf patients. METHODOLOGY: The study involved 60 prellingually deaf patients aged 10 to 23 years with oral speech skills. To assess the quality of the CI processor tuning, in addition to traditional methods, a special battery of psychoacoustic tests was used. The first block of tests assessed the perception of the basic characteristics of sound signals (duration, temporal structure, spectrum, timbre) and was used to assess the initial setting. The second block of tests, intended for patients with experience using CI, included tasks to distinguish acoustically similar and dynamically changing signals, etc. RESULTS: At the end of the initial CI setup session, patients with short signal pe rception problems were identified. Adjusting the frequency of electrical stimulation in patients has increased their ability to distinguish between sounds. During the second tuning session of the CI processor, 6 months later, a group of patients with difficulties in perceiving acoustic information in the low-frequency range was identified - distinguishing melodic intervals, changing the pitch of sounds, highlighting the voice of the target speaker. The «problem» patients underwent additional correction of the CI processor setting and the corresponding auditory training, which improved the test performance and subjective perception of sounds. CONCLUSION: The use of psychoacoustic tests expands the possibilities of fine tuning the CI processor, taking into account the individual characteristics of the patient's auditory perception at different stages of CI use, especially in «problem» patients.

The history of the antibody as a tool

xlomafota13 shared this article with you from Inoreader The history of the antibody as a tool Via histochem Acta Histochem. 2021 Mar 12;123(4):151710. doi: 10.1016/j.acthis.2021.151710. Online ahead of print. ABSTRACT Antibodies are essential tools in modern science and medicine, however the history leading to the use of antibodies as tools has not been well-described. The objective of this paper is to analyze the history of immunology from smallpox inoculation to the production of monoclonal antibodies, and to identify turning points in immunological theory leading to the emergenc e of antibody-tools. In the early 1700's, Western medicine adopted smallpox inoculation from Turkey, along with the idea of acquired immunity. The Germ Theory of disease had to replace spontaneous generation and miasma theory in the 1880's, however, before inoculation could successfully be applied to other diseases. Inquiry into acquired immunity led to the idea of the "antibody" in the 1890's, and the use of antiserum to identify bacteria. Immunostaining was invented in 1942 by repurposing antibody-dye conjugates originally intended as antibiotics. Monoclonal antibody-producing hybridomas were similarly invented in 1975 by repurposing techniques from virology and genetics.

Hill‐based musculoskeletal model for a fracture reduction robot

xlomafota13 shared this article with you from Inoreader Hill‐based musculoskeletal model for a fracture reduction robot Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Background The introduction of fracture reduction robot can solve the problem of large reduction forces during fracture reduction surgeries and the need to collect multiple medical images. However, because its safety has not been certified, there are few academic achievements on this type of robot. To calculate the safety factor during its operation, a musculoskeletal model needs to be established to study the constraints of muscles on the robot. The existing academic achievements of musculoskeletal modelling are mainly for application such as rehabilitation treatment and collision in car accidents. Methods A musculoskeletal model applied to the fracture reduction robot is proposed in this paper. First, by comparing the characteristics of mainstream muscle models and combining the biological characteristics of the anesthetised muscles, the Hill model was selected as the muscle model for this study. Second, based on the motion composition of six spatial degrees of freedom, five basic fractural malposition situations are proposed. Then, a 170‐cm tall male musculoskeletal model was built in Opensim. Based on this model, the muscle force curves of the above malposition situations are calculated. Finally, a similar musculoskeletal model was established in Adams, and the accuracy of its muscle force data was tested. The study is approved by the ethics committee of the Rehabilitation Hospital, National Research Center for Rehabilitation Technical Aids, Beijing, China. Results The muscle force curve of Opensim and Adams model under situations of five basic malposition are compared. Most of the correlation coefficients are in the range of 0.98–0.99. The overall correlation coefficient is greater than 0.95. Conclusions The simulation results prove that this model can be used for the safety assessment of the fracture reduction robots. This model will be served as an environmental constraint to study the control of fracture reduction robot. View on the web Inoreader. Take back control of your news feed.

Just Do It—Everyone Should Follow the Guidelines

xlomafota13 shared this article with you from Inoreader Just Do It—Everyone Should Follow the Guidelines Via JAMA Otolaryngology–Head & Neck Surgery Current Issue Hearing loss is the most common congenital sensory impairment, and by age 19 years, 15.2% of participants in the 2009 to 2010 National Health and Nutrition Examination Survey had a measurable degree of hearing loss. In this issue of JAMA Otolaryngology–Head & Neck Surgery, Qian et al investigated factors associated with variability in following 2016 International Pediatric Otolaryngology Group (IPOG) consensus guidelines for diagnostic evaluation in pediatric patients with sensorineural hearing loss (SNHL). They used data for 53 711 unique patients from the Optum Clinformatics Data Mart, a nationally representative database containing claims from a large national private insurer with an annual sample size of 12 million unique patients. They recorded patient visits in hospitals, emergency departments, and outpatient practices in p ediatrics, otolaryngology, and audiology from January 1, 2008, to December 31, 2018. Assessed variables included the degree and type of hearing loss and diagnostic tests ordered, including electrocardiogram, cytomegalovirus (CMV) testing, magnetic resonance imaging (MRI), computed tomography (CT), and genetic testing, and interventions including cochlear implant (CI) surgery, hearing aid (HA)–related services, and speech language pathology (SLP) therapy. They collected demographic characteristics, socioeconomic status, clinician type, and cost data. The results of the study by Qian et al showed that national practice patterns were not consistent with the IPOG guidelines, with only 30% of children with SNHL having some form of diagnostic testing. Undergoing diagnostic testing was associated with increased use of interventions, including HA services, CI, and SLP services. Even after accounting for diagnostic testing, racial/ethnic and economic disparities persisted in SLP and HA ser vices, although not for CI. Although generally genetic testing and MRI use increased and CT use declined, CMV and genetic testing remained underused. After controlling for demographic and clinical factors, racial/ethnic and economic disparities were seen for CT, electrocardiogram, MRI, and genetic testing. Importantly, the type of clinician that the patient saw was associated with the odds of receiving certain diagnostic tests and interventions, with pediatric otolaryngologists and geneticists more likely to order all diagnostic modalities and recommend SLP services compared with general otolaryngologists, neurotologists and nonotolaryngologists.

Acute Laryngeal Injury After Intubation

xlomafota13 shared this article with you from Inoreader Acute Laryngeal Injury After Intubation Via JAMA Otolaryngology–Head & Neck Surgery Current Issue Although intubation is often necessary and lifesaving, there are known laryngotracheal consequences. Otolaryngologists are all too familiar with the vocal-fold damage and inflammatory conditions that are associated with prolonged intubation because patients often present in the hospital or clinic with dysphonia or dyspnea. The size of the endotracheal tube and the duration of intubation are known to be risk factors for postintubation damage. The pathophysiology is well understood to be caused by pressure-induced damage to the mucosal and cartilaginous structures of the larynx. However, despite this knowledge, laryngeal damage is often considered unavoidable, accrued as a result of a lifesaving stay in an intensive care unit. The resulting disease state can be so functionally devastating and difficult to treat that many otolaryngologists are left wondering: is there something we can do to prevent this from happening?
