Article Abstract

Background: Oral complications such as parageusia, xerostomia, and oral ulcers are frequently observed in patients with COVID-19. The aim of this study was to understand the oral complications and their influencing factors during the two waves of the COVID-19 pandemic in China between December 2022 and May 2023.

Methods: A total of 347 patients during the COVID-19 pandemic from December 2022 and January 2023 and 163 patients during the second COVID-19 pandemic were recruited through the Disease Prevention and Control Reporting System. Data on oral complications were collected via researcher-made questionnaires.

Results: During both pandemic periods, more than 50% of the subjects developed oral complications. Specifically, the incidence of parageusia, pathological tongue coating, and xerostomia all exceeded 20%, while the incidence of oral ulcers surpassed 7%. Patients with allotriosmia and xerostomia had a significantly higher likelihood of developing other oral complications. Hospitalized patients requiring supplemental oxygen had a significantly higher incidence of oral complications.

Conclusions: The results of our study underline that oral complications during the COVID-19 pandemic are prevalent, and their incidence has not decreased during the subsequent pandemic. In the context of the ongoing global spread of COVID-19, this study lays the foundation for physicians in recognizing and managing oral complications, which will improve the oral health of communities globally.

Lipomas are benign soft tissue tumors composed of mature adipocytes, commonly found in subcutaneous tissues. Despite their prevalence in various body regions, they are relatively rare in the oral and maxillofacial regions. This study retrospectively analyzed the clinical and imaging characteristics, as well as the treatment outcomes of 57 patients diagnosed with lipoma.

Rationale: We report the efficacy of combination prednisolone and intravenous (IV) rituximab as an immunosuppressive regimen for a young male presenting with extensive venous thromboembolism including a submassive pulmonary embolism secondary to life-threatening nephrotic syndrome from very high risk anti-phospholipase-A2 receptor (PLA2R) positive membranous nephropathy. Initial treatment was with mechanical thrombectomy and anticoagulation. Thereafter, oral prednisolone was initiated to induce remission, during a period of uninterrupted anticoagulation.

Rationale: When gland-preserving treatments are unsuccessful, sialoadenectomy is typically conducted for patients afflicted with submandibular gland diseases. The definitive treatment modality for these individuals is the removal of both the gland and the associated ducts. During surgery, the gland and the majority of the ducts can be excised utilizing the lateral transcervical approach, with residual ducts unlikely to develop pathology.
