Close Associations of Gum Bleeding with Systemic Diseases in Late Adolescence

Background: Though it is well known that periodontal diseases are associated with various systemic diseases in adults, the associations in late adolescents have not been adequately elucidated. We investigated the association between gum bleeding (a major symptom of periodontal diseases) and common systemic diseases in late adolescents: allergic, respiratory, and otorhinolaryngologic diseases. Methods: We conducted a retrospective review of the mandatory medical questionnaires administered as a part of legally required freshman medical checkup between April 2017 and April 2019 at the University of Tokyo. Among the total of 9376 sets of responses, 9098 sets from students aged less than 20 were analyzed. An χ2 test and univariate and multivariate binomial logistic regression analyses were performed using SAS ver. 9.4. A value of p < 0.05 was accepted as significant. Results: According to the questionnaire data, 3321 students (36.5%; 2780 males and 541 females) responded that they experienced gum bleeding whenever they brushed their teeth. These students had significantly higher incidence rates of otitis media/externa and asthma/cough-variant asthma (p = 0.001 and p = 0.006, respectively). The results of the multivariate analysis showed significant rates of the following complications among these students: (1) otitis media/externa (odds ratio (OR) 1.691; 95% confidence interval (CI): 1.193–2.396; p = 0.003), (2) asthma/cough-variant asthma (OR 1.303; 95% CI: 1.091–1.556; p = 0.003), and (3) male gender (OR 1.536; 95% CI: 1.337–1.765; p < 0.001). Conclusions: Gum bleeding was closely associated with otitis media/externa and asthma in late adolescents. Our study reinforces new evidence about the association between periodontal diseases and asthma, and it reveals a novel and close association between gum bleeding and otitis media/externa.

Impact of Endoplasmic Reticulum Stress in Otorhinolaryngologic Diseases

The endoplasmic reticulum (ER) is an important organelle for normal cellular function and homeostasis in most living things. ER stress, which impairs ER function, occurs when the ER is overwhelmed by newly introduced immature proteins or when calcium in the ER is depleted. A number of diseases are associated with ER stress, including otorhinolaryngological diseases. The relationship between ER stress and otorhinolaryngologic conditions has been the subject of investigation over the last decade. Among otologic diseases associated with ER stress are otitis media and hearing loss. In rhinologic diseases, chronic rhinosinusitis, allergic rhinitis, and obstructive sleep apnea are also significantly associated with ER stress. In this review, we provide a comprehensive overview of the relationship between ER stress and otorhinolaryngological diseases, focusing on the current state of knowledge and mechanisms that link ER stress and otorhinolaryngologic diseases.

A mikrobiom szerepe a fül-orr-gégészetben

Our health is highly determined by the diverse microbial community living within our body and upon our skin. Balance among the members of the commensal microbiota is essential for the preservation of health. New generation sequencing is a rapid, sensitive method for determining the whole microbiome without prior hypothesis and also gives information on the resistance and virulence status. Application of this method can help to identify the pathogens contributing to different diseases, and also the protective bacteria inhibiting their growth. Detecting the changes of the microbiome helps to identify new therapeutic targets and establish targeted antibiotic therapy. Broad-spectrum antibiotics also act against the beneficial members of the microbial flora, which may lead to the development of recurrent or chronic disease. Ear, nose and throat infections are the most common infective diseases in humans and the leading cause for antibiotic prescription worldwide. In recent years, many studies using molecular biology methods were performed examining the microbiome of healthy humans and in otorhinolaryngologic diseases. In the present work, the authors review the changes of the microbiological communities in the healthy state and in various pathologic states in the anatomic regions of the ear, nose and throat.

Introducción: La granulomatosis con poliangeítis (de Wegener) es una enfermedad poco frecuente, sin embargo, el 80 a 90% de los casos tienen manifestaciones otorrinolaringológicas, muchas como único síntoma inicial de la enfermedad. Objetivos: El propósito de este artículo es revisar la literatura disponible actualizada sobre granulomatosis con poliangeítis: manifestaciones clínicas, estándares de enfoque, diagnóstico y tratamiento en otorrinolaringología. Diseño: Revisión narrativa de la literatura. Materiales y métodos: Revisión de la literatura mediante búsqueda selectiva por términos MeSH: Otorhinolaryngologic Diseases, Granulomatosis with polyangiitis, Wegener Granulomatosis, de las bases de datos:MEDLINE, Current Contents, Cochrane, Pubmed y Scielo, entre los años 2000 y 2014. Resultados: Se revisaron 39 artículos según los requerimientos de los objetivos. La evidencia científica actual reconoce la importancia del conocimiento sobre granulomatosis con poliangeítis (de Wegener) en otorrinolaringología, para obtener diagnósticos tempranos y ofrecer manejos oportunos. Conclusiones: El diagnóstico y tratamiento tempranos de la granulomatosis con poliangeítis (de Wegener) son las únicas herramientas para mejorar el pronóstico y calidad de vida de los pacientes con esta enfermedad.Introduction: Granulomatosis with polyangiitis (Wegener’s) is a rare disease,however 80% to 90% of the cases have otolaryngologic manifestations, many as initial symptoms of the disease.
