Background
This study aims to find the chemosensitive dysfunction incidence in COVID-19-positive patients and its recovery.
We collected the data from sixty-five patients, all COVID-19 positive, quarantined in-hospital between 5 April 2020 and 17 May 2020, by a questionnaire distributed in the quarantine ward.
Results
Smell dysfunction appeared in 89.23% with or without other symptoms of COVID-19. 39.66% of them recovered the sense of smell. Taste dysfunction found in 83.08% patients with other COVID-19 symptoms. Only 29.63% of them recovered. The recovery took 1–3 weeks, and most cases recovered within 1 week or less. 18.46% and 15.38% had smell and taste dysfunction, respectively, as the only symptom before COVID-19 confirmation. Most of the chemosensitive dysfunction affected the 4th decade of age in this study.
Conclusion
Chemosensitive dysfunction is associated with coronavirus disease and may be the only symptom that presents the disease. This makes the ENT doctors the first line of contact with the coronavirus. Further objective studies are required to cover chemosensitive dysfunctions, as the recognition of this dysfunction may help the diagnosis of COVID-19, and prevent the spread of this disease.
AbstractBackground: the objective of this study is to find the incidence of chemosensitive dysfunction in COVID-19 positive patients and its recovery.We collected the data from Sixty-five patients, all Covid-19 positive, quarantined in hospital between 5.4.2020 and 17.5.2020, by a questionnaire distributed the quarantine ward.Results: Smell dysfunction appeared in (89.23%) with or without other symptoms of COVID-19. (39.66%) had the sense of smell recovered. Taste dysfunction was found in (83.08%) patients with other COVID-19 symptoms. only (29.63%) of them recovered. The recovery took 1-3 weeks, most cases within 1 week or less. As the only symptom before COVID-19 confirmation, (18.46%) and (15.38%) had smell dysfunction and taste dysfunction respectively. Most of the chemosensitive dysfunction affected the 4th decade of age.Conclusion: Chemosensitive dysfunction is associated with COVID-19, and may be the only presenting symptom of the disease. This makes the ENT doctors in the first line of contact with corona virus. Further objective studies are required to cover chemosensitive dysfunctions, as the recognition of this dysfunction may help the diagnosis of COVID-19, and prevent the spread of this disease.
MicroRNAs (miRNA) are a group of small non-coding RNAs that regulate gene expression at the RNA level. MicroRNAs have positive regulatory effects on protein translation processes and often induce their performance by binding to the 3'-UTR mRNA region. Also, microRNAs are involved in various cellular processes, including development, cell division, cell signaling, and cell growth, and generally play an effective role in the cell cycle and control of physiological processes and cell pathology. Several studies confirm that microRNAs play an important role in the initiation and progression of cancer, and many of them act as oncogenes and tumor suppressors. On the other hand, microRNAs are important stimulating factors that can act as biomarkers in the diagnosis and prognosis of various types of cancer, and in many cases, the occurrence of mutations in microRNAs and open-reading templates can lead to cancer. MicroRNAs also play an effective role in regulating gene expression. Biological studies have shown that about 30% of all genes and the majority of genetic pathways are regulated by microRNAs. In general, microRNAs and their target molecules are potential biological goals for primary screening, targeted treatment, and pharmaceutical resistance, and identifying them provides a clear prospect for a better understanding of the pathways leading to cancer.
