COVID-19-associated parotitis and sublingual gland sialadenitis.

The COVID-19 mainly affects the respiratory system; however, a variety of atypical manifestations of this disease have been also reported. Herein, we report a case of a man in his late 50s with severe COVID-19 presenting with parotitis and sublingual gland sialadenitis. Six days after admission, swelling in the bilateral preauricular and lower jaw areas developed. CT demonstrated parotid and sublingual gland enlargement with surrounding fat stranding, indicating sialadenitis. This case suggests that, in the present COVID-19 pandemic, COVID-19 should be included in the differential diagnosis of sialadenitis and prompt isolation should be considered to reduce the spread of infection.

COVID-19-associated Parotid Gland Abscess.

BACKGROUND: Human infection with the SARS-CoV-2 virus has caused a pandemic characterized by a plethora of diseases, of which those affecting the internal organs and nervous system can have severe, life-threatening consequences. Among the manifestations of the disease at the viral entry site, diseases in oral mucosa adnexa are rarely reported. This case report describes a COVID-19-associated aggravating parotid gland disease. CASE REPORT: The 47-year-old, SARS-CoV-2-positive male patient, already hospitalized and now in need of ventilation, had been referred for intensive care treatment due to increasing respiratory problems. A unilateral swelling of the cheek was noticed, the cause of which was initially a parotid gland infection. Examination ruled out mechanical causes of the parotid gland. During further treatment, the patient developed a parotid abscess, which was drained extra orally. CONCLUSION: The oral cavity is primarily considered as a reservoir of the pathogen. There is an increasing number of reports detailing inflammation of the major salivary glands associated with SARS-CoV-2 virus. Knowledge of this association facilitates therapeutic decisions.

[Bilateral acute purulent mumps in patients with COVID-19]. / Dvustoronnii ostryi gnoinyi parotit u bol'nykh s COVID-19.

THE AIM OF THE STUDY: To familiarize dentists with the features of the clinical course of acute purulent mumps occurring in patients with COVID-19. MATERIAL AND METHODS: Four patients aged 73 to 89 years with acute bilateral purulent mumps, which occurred against the background of COVID-19, were under observation. The patients were treated for COVID-19, and acute purulent mumps was also treated. RESULTS: As a result of treatment, two patients were discharged in satisfactory condition on the 9th and 10th days under medical supervision at their place of residence. Their mumps phenomena have completely subsided. Two patients died from acute respiratory failure, cerebral edema, septic condition, acute renal and hepatic insufficiency. From the parotid glands, acute inflammatory phenomena subsided. CONCLUSION: It was found that one of the complications of COVID-19 may be the development of acute bilateral purulent mumps, which aggravated the course of the underlying disease. Inflammation of the parotid glands proceeded according to the type of acute postoperative mumps against the background of a sharp decrease in the secretory activity of the salivary glands according to the type of asialia. Timely comprehensive treatment of acute mumps allows in some cases to avoid a fatal outcome.

Haemostatic devices in parotid surgery: a systematic review.

OBJECTIVE: The Harmonic Scalpel and Ligasure (Covidien) devices are commonly used in head and neck surgery. Parotidectomy is a complex and intricate surgery that requires careful dissection of the facial nerve. This study aimed to compare surgical outcomes in parotidectomy using these haemostatic devices with traditional scalpel and cautery. METHOD: A systematic review of the literature was performed with subsequent meta-analysis of seven studies that compared the use of haemostatic devices to traditional scalpel and cautery in parotidectomy. Outcome measures included: temporary facial paresis, operating time, intra-operative blood loss, post-operative drain output and length of hospital stay. RESULTS: A total of 7 studies representing 675 patients were identified: 372 patients were treated with haemostatic devices, and 303 patients were treated with scalpel and cautery. Statistically significant outcomes favouring the use of haemostatic devices included operating time, intra-operative blood loss and post-operative drain output. Outcome measures that did not favour either treatment included facial nerve paresis and length of hospital stay. CONCLUSION: Overall, haemostatic devices were found to reduce operating time, intra-operative blood loss and post-operative drain output.

Evaluating resident involvement and the 'July effect' in parotidectomy.

OBJECTIVE: This study aimed to evaluate the effect of resident involvement and the 'July effect' on peri-operative complications after parotidectomy. METHOD: The American College of Surgeons National Surgical Quality Improvement Program database was queried for parotidectomy procedures with resident involvement between 2005 and 2014. RESULTS: There were 11 733 cases were identified, of which 932 involved resident participation (7.9 per cent). Resident involvement resulted in a significantly lower reoperation rate (adjusted odds ratio, 0.18; 95 per cent confidence interval, 0.05-0.73; p = 0.02) and readmission rate (adjusted odds ratios 0.30; 95 per cent confidence interval, 0.11-0.80; p = 0.02). However, resident involvement was associated with a mean 24 minutes longer adjusted operative time and 23.5 per cent longer adjusted total hospital length of stay (respective p < 0.01). No significant difference in surgical or medical complication rates or mortality was found when comparing cases among academic quarters. CONCLUSION: Resident participation is associated with significantly decreased reoperation and readmission rates as well as longer mean operative times and total length of stay. Resident transitions during July are not associated with increased risk of adverse peri-operative outcomes after parotidectomy.

Discovery of new salivary gland - A substantial histological analysis.

Regardless of the COVID-19 pandemic in 2020, discovering a new salivary gland turned into all the rage among the medical fraternity. The significance of the disclosure has been correlated with its clinical relevance in radiotherapy of oropharyngeal carcinoma. However, there are views against this new revelation, owing to the lack of substantial evidence. We have endeavoured to illuminate Tubarial glands with potential shreds of evidence.

Head and neck surgery during the coronavirus-19 pandemic: The University of California San Francisco experience.

BACKGROUND: Guidelines regarding head and neck surgical care have evolved during the coronavirus-19 (COVID-19) pandemic. Data on operative management have been limited. METHODS: We compared two cohorts of patients undergoing head and neck or reconstructive surgery between March 16, 2019 and April 16, 2019 (pre-COVID-19) and March 16, 2020 and April 16, 2020 (COVID-19) at an academic center. Perioperative, intraoperative, and postoperative outcomes were recorded. RESULTS: There were 63 operations during COVID-19 and 84 operations during pre-COVID-19. During COVID-19, a smaller proportion of patients had benign pathology (12% vs 20%, respectively) and underwent thyroid procedures (2% vs 23%) while a greater proportion of patients underwent microvascular reconstruction±ablation (24% vs 12%,). Operative times increased, especially among patients undergoing microvascular reconstruction±ablation (687 ± 112 vs 596 ± 91 minutes, P = .04). Complication rates and length of stay were similar. CONCLUSIONS: During COVID-19, perioperative outcomes were similar, operative time increased, and there were no recorded transmissions to staff or patients. Continued surgical management of head and neck cancer patients can be provided safely.

Systematic analysis of ACE2 and TMPRSS2 expression in salivary glands reveals underlying transmission mechanism caused by SARS-CoV-2.

Coronavirus disease 2019 (COVID-19) is a global pandemic that has caused severe health threats and fatalities in almost all communities. Studies have detected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in saliva with a viral load that lasts for a long period. However, researchers are yet to establish whether SARS-CoV-2 can directly enter the salivary glands. Therefore, this study aimed to assess the presence of angiotensin-converting enzyme 2 (ACE2)/transmembrane serine proteases 2 (TMPRSS2) expression in salivary glands using publicly available databases. The distribution of ACE2 and TMPRSSs family in salivary gland tissue and other tissues was analyzed. The Genotype-Tissue Expression dataset was employed to explore the ACE2 and TMPRSS2 expression in various body organs and salivary glands in a healthy population. The single-cell sequencing data for salivary gland samples (including submandibular salivary gland and parotid gland) from mice were collected and analyzed. The components and proportions of salivary gland cells expressing the key protease TMPRSSs family were analyzed. Transcriptome data analysis showed that ACE2 and TMPRSS2 were expressed in salivary glands. The expression levels of ACE2 and TMPRSS2 were marginal without significant differences in different age groups or between men and women. Single-cell RNA sequence analysis indicated that TMPRSS2 was mainly expressed in salivary gland epithelial cells. We speculate that SARS-CoV-2 may be entered in salivary glands.
