Background: Nasal chondromesenchymal hamartoma (NCMH) is a rare benign tumor almost always found in children. NCMH was first described by McDermott in 1998. To the best our knowledge, about 50 NCMH cases have been reported worldwide with very few adult cases and no long-term follow-ups. Case Presentation: Here, we report a 43-year-old woman who referred to the Otolaryngology Clinic of Payambar Azam Hospital, Bandar Abbas, Iran, in 2008, with a one-year history of progressive left-sided nasal obstruction that had not relieved with topical nasal decongestants and steroid sprays. A unilateral left-sided nasal soft-tissue mass was found upon examination. Histological and immunohistochemical analyses were consistent with NCMH. Trans-nasal endoscopic excision showed good results and no sign of recurrence has been observed after 12 years of regular follow-up. Conclusion: Awareness of imaging and immunohistochemical characteristics of NCMH combined with the probability of presentation in the adult population are necessary for correct diagnosis and adequate therapy.
Tobacco smoke includes over 4,000 potentially harmful components. This study aimed to collect relevant content to evaluate the association between smoking and sinonasal diseases. PubMed, Scopus, Web of Sciences, and Google Scholar databases were searched for related articles from inception until 2021. Of the overall 560 retrieved articles, 67 cases remained for review after the exclusion of duplicates and unrelated papers. Tobacco smoke, whether first- or second-hand, is harmful to the nose and sinuses. Smoking is linked to various sinonasal disorders, including chronic rhinosinusitis (CRS), olfactory impairment, nasal polyps, allergic and non-allergic rhinitis, and certain cancers. The formation of bacterial biofilms, dysfunctional mucociliary clearance, oxidative stress, inflammation, apoptosis and cytotoxicity, and structural changes appear to be some of the potential mechanisms through which tobacco smoke affects the sinuses and the nose. Clinicians should consider the negative consequences of smoking on sinonasal disorders when treating patients with these conditions. Cessation of smoking may benefit these patients’ health.
Background: The global public health and economic systems have been severely damaged by the coronavirus disease 2019 (COVID-19) pandemic. Olfactory dysfunction (OD) is one of the most prevalent symptoms experienced by COVID-19 patients, documented in clinical practice. In some individuals, OD is the first or the sole clinical symptom. In this review, the clinical characteristics, causes, evaluation procedures, prognosis, and available treatments of COVID-19-induced OD were examined. Methods: The PubMed, Scopus, Web of Sciences, and Google Scholar databases were searched for the related articles from inception until August 2022. Results: OD appears to be common in COVID-19, particularly in younger individuals and women and those with milder disease. Even though the issue is still unresolved, current research suggests that COVID-19-related OD is not caused by direct injury to olfactory sensory neurons but instead is a result of indirect injury to these cells. Moreover, effective therapeutic methods are inadequate despite the high prevalence of COVID-19-related OD. Conclusion: The focus of medical practice regarding COVID-19-related OD should be on identifying individuals with a poor prognosis who may benefit from early management to prevent complications, e.g., depression and anxiety, because COVID-19 OD generally has a good prognosis and quick recovery time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
