“…Modified Liverpool Peritonsillar abscess Score (LPS) (the components are unilateral sore throat, trismus, sex [male], pharyngeal voice change [hot potato voice]) is also one of the useful tools. It demonstrates a high negative predictive value of 99% and high sensitivity of 98% for diagnosing peritonsillar abscess [19] . In our case, she experienced left-sided sore throat, dysphagia, and trismus.…”

Peritonsillar abscess caused by Prevotella bivia during home quarantine for coronavirus disease 2019

et al. 2022

Rationale:Since late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had rapidly spread worldwide, resulting in a pandemic. Patients with coronavirus disease 2019 (COVID-19) have difficulty in visiting clinics in person during pandemic because they might be encouraged to quarantine at home with supportive care. Peritonsillar abscess rarely coexists with COVID-19; however, patients with SARS-CoV-2 infection could get co-infections or become superinfected with other microorganisms which could cause peritonsillar abscess. We herein describe a case of peritonsillar abscess caused by Prevotella bivia that occurred as a co-infection with COVID-19 during home quarantine.Patient concerns:A 32-year-old Asian woman who was diagnosed with COVID-19 was instructed to stay home for quarantine. Her pharyngeal discomfort worsened, and she experienced trismus and dysphagia. An emergent visiting doctor referred her to our hospital. Contrast-enhanced computed tomography showed peritonsillar abscess findings, following which we referred her to an ear, nose, throat specialist. Prevotella bivia was identified on needle aspiration pus culture; however, two sets of blood and throat cultures were negative.Diagnosis:A definitive diagnosis of acute COVID-19 and peritonsillar abscess due to Prevotella bivia was made.Interventions:An antibiotic drug, antiviral drug, and adjunctive steroid were administered intravenously.Outcomes:Her symptoms improved without the need for incision and drainage, and she was discharged on day 7.Conclusion:Patients with suspected peritonsillar abscess should be triaged and referred to ear, nose, throat specialists appropriately. Scoring systems, such as modified Liverpool peritonsillar abscess score or the guidelines criteria might be useful tools to triage patients. During the early phase of SARS-CoV-2 infection, administration of corticosteroids is not recommended. When adjunctive steroids are considered for peritonsillar abscess, prior to or simultaneous use of the antiviral agent remdesivir for COVID-19 might be recommended.

[ 19 ] In our case, she experienced left-sided sore throat, dysphagia, and trismus. She was considered suitable for further examination because her conditions met the ENT UK criteria and her modified LPS was 5 points.…”

“… 30 , 31 The Liverpool Peritonsillar Abscess Score has undergone modification to support the triage of suspected cases without oral examination, thereby limiting clinicians’ risk of exposure. 32 However, adequate access and supply of appropriate PPE, as well as improved patient testing, must be ensured to protect both patients and staff, and to avoid compromising patient care.…”

Improving the management of suspected tonsillitis and peritonsillar abscess referred to ENT – a coronavirus disease 2019 service improvement

et al. 2021

Background. The impact of coronavirus disease 2019 on healthcare has led to rapid changes in otolaryngology service provisions. As such, new standard operating procedures for the management of suspected tonsillitis or quinsy were implemented in our centre. Methods.A retrospective audit was performed of acute referrals to ENT of patients with suspected tonsillitis, peritonsillar cellulitis or quinsy, during the 10 weeks before (group 1) and 10 weeks after (group 2) implementation of the new standard operating procedures.Results. Group 2 received fewer referrals. Fewer nasendoscopies were performed and corticosteroid use was reduced. The frequency of quinsy drainage performed under local anaesthetic increased, although the difference was not statistically significant. Hospital admission rates decreased from 56.1 to 20.4 per cent,
