RESUMEN
BACKGROUND: COVID-19, caused by SARS-CoV-2 has become the most threatening issue to all populations around the world. It is, directly and indirectly, affecting all of us and thus, is an emerging topic dealt in global health. To avoid the infection, various studies have been done and are still ongoing. COVID-19 cases are reported all over the globe, and among the millions of cases, genetic similarity may be seen. The genetical common features seen within confirmed cases may help outline the tendency of infection and degree severity of the disease. Here, we reviewed multiple papers on SNPs related to SARS-CoV-2 infection and analyzed their results. METHODS: The PubMed databases were searched for papers discussing SNPs associated with SARS-CoV-2 infection and severity. Clinical studies with human patients and statistically showing the relevance of the SNP with virus infection were included. Quality Assessment of all papers was done with Newcastle Ottawa Scale. RESULTS: In the analysis, 21 full-text literature out of 2956 screened titles and abstracts, including 63,496 cases, were included. All were human-based clinical studies, some based on certain regions gathered patient data and some based on big databases obtained online. ACE2, TMPRSS2, and IFITM3 are the genes mentioned most frequently that are related to SARS-CoV-2 infection. 20 out of 21 studies mentioned one or more of those genes. The relevant genes according to SNPs were also analyzed. rs12252-C, rs143936283, rs2285666, rs41303171, and rs35803318 are the SNPs that were mentioned at least twice in two different studies. CONCLUSIONS: We found that ACE2, TMPRSS2, and IFITM3 are the major genes that are involved in SARS-CoV-2 infection. The mentioned SNPs were all related to one or more of the above-mentioned genes. There were discussions on certain SNPs that increased the infection and severity to certain groups more than the others. However, as there is limited follow-up and data due to a shortage of time history of the disease, studies may be limited.

CONCLUSIONS: The intraoral approach for removal of the plunging ranula is a safe and effective surgical approach as a primary treatment modality for plunging ranula. OBJECTIVES: Although sclerotherapy is applied for plunging ranula, it can be primarily treated with surgery such as marsupialization, simple excision, and transcervical excision. This study was performed to assess the results of the intraoral approach for the treatment of plunging ranula. METHODS: This prospective clinical study comprised a total of 23 patients with plunging ranula treated by the intraoral approach. RESULTS: All patients had complete removal of the sublingual gland with evacuation of cystic fluid. The cystic wall of the ranula could be dissected completely in only four patients, and in eight patients it was only possible to drain the cystic fluid. However, in 11 patients we could not dissect the cystic wall completely. Rupture of ranula developed in all patients during the intraoral dissection. Recurrence was not detected in any of the patients during the median follow-up period of 14 months after the intraoral excision. There were no complications or external scarring.
