Predicting failure of detection of peritonsillar abscess with ultrasound in pediatric populations.

PURPOSE: Some patients require additional imaging following ultrasound (US) to definitively diagnose a peritonsillar abscess (PTA), delaying intervention and disease resolution. We seek to evaluate patient characteristics which may predispose to a secondary imaging requirement to diagnose PTA, in order to better understand ultrasound limitations and predict who will require additional studies. MATERIALS AND METHODS: Retrospective chart review of patients with an US for suspected PTA between July 2017 and July 2020. Patient age, weight, and clinical characteristics, such as pain, trismus, and reduced neck range of motion (ROM) were collected. The need for additional imaging, subsequent surgical intervention, and hospital length of stay (LOS) were also recorded. RESULTS: Of 411 qualifying patients, 73 underwent additional imaging. Patients who required additional imaging were younger (9.8 vs 11.3 years, p = 0.026) and more likely to have decreased neck ROM (17.8 vs 5.3 %, p = 0.001). Surgical intervention was performed more commonly (27.4 vs 14.8 %, p = 0.015) and hospital LOS was longer (24.0 vs 5.0 h, p < 0.001) in those with secondary imaging. CONCLUSIONS: Specific patient characteristics, such as younger age and decreased neck range of motion, are associated with a higher need for additional imaging. Additionally, the need for additional imaging is associated with a longer hospital LOS and increased likelihood of surgical intervention. Nearly 18 % of patients who underwent US evaluation of PTA required secondary imaging. Although transcervical US remains an excellent tool for diagnosing PTA, this data supports the utility of secondary imaging in certain instances.

Outcomes of abscess tonsillectomy in patients awaiting tonsillectomy: A comparison with interval tonsillectomy.

PURPOSE: Peritonsillar abscesses (PTA) occasionally occur in patients who have a concurrent history of recurrent tonsillitis or prior PTA episodes. These patients sometimes meet the indications for elective tonsillectomy even prior to the current PTA event. Abscess ("Quinsy") tonsillectomy (QT) could serve as definitive treatment in this specific subgroup, though it is not performed often. The purpose of this study was to compare the perioperative outcomes between immediate QT and tonsillectomy performed several days (delayed QT) or weeks (Interval tonsillectomy, IT) after incision and drainage (I&D) of the PTA in this specific subgroup. MATERIALS AND METHODS: A retrospective perioperative outcomes analysis of patients undergoing tonsillectomy (2002-2022) compared QT to delayed QT and IT in patients with PTA meeting AAO-HNS elective tonsillectomy criteria. RESULTS: 110 patients were included: 55 underwent IT, 36 underwent delayed QT, and 19 underwent immediate QT. Postoperative hemorrhage rates were 14.5 %, 11.1 %, and 5.3 % for IT, delayed QT, and immediate QT, respectively (P = 0.08). Mean hospitalization durations were 7.98, 6.92, and 5.37 days for IT, delayed QT, and immediate QT, respectively (P < 0.01). IT had a higher readmission rate due to pain compared to QT (14.5 % vs. 1.9 %, p = 0.032). CONCLUSION: Immediate QT in PTA patients eligible for elective tonsillectomy is associated with lower postoperative hemorrhage, shorter admission time, and potentially reduced postoperative pain compared to I&D and delayed or interval tonsillectomy. These findings suggest that immediate QT should be considered as a primary treatment in this subgroup of eligible patients.

Diseases associated with subsequent peritonsillar abscess: a case-control-study from ENT practices in Germany.

OBJECTIVE: Peritonsillar abscess (PTA) is the most common deep soft tissue infection necessitating surgical intervention in the head and neck region. Potential causes include infections of the palatine tonsils, palatine glands, or branchiogenic rudiments ("acute tonsillitis hypothesis" vs. "Weber's gland hypothesis"). Understanding the currently still unknown predominant cause is crucial for guiding therapeutic strategies, such as abscess tonsillectomy versus incision and drainage alone. This study aims to investigate the pre-diagnoses associated with subsequent PTA using a nationally representative practice database in Germany. METHODS: Data were collected from 195 ENT practices across Germany utilizing the nationally representative practice database IQVIA™ Disease Analyzer. Included were patients aged 18 years and older with a first diagnosis of PTA (index date) between January 2005 and December 2022 and a minimum observation period of 12 months preceding the index date. These patients were matched (1:5) with controls without PTA, based on age, sex, and index year. Frequencies of prior diagnoses coded according to ICD-10 in the 12 months preceding the index date were computed. The association between prior diagnoses and PTA was evaluated using multivariable logistic regression (MLR) and sensitivity analysis (SA). RESULTS: A total of 5,325 cases were compared with 26,725 controls in the multivariable logistic regression (MLR) analysis, and 16,251 cases were compared with 81,255 controls in the sensitivity analysis (SA). Mean age was 45.3 ± 18.3 years (MLR) and 41.9 ± 16.7 years (SA). The proportion of female patients was 51.8% (MLR) and 46.9% (SA), respectively. MLR showed the strongest associations with PTA for the prior diagnoses of "acute tonsillitis" (odds ratio, OR: 6.71; 95% CI: 5.81-7.74), "chronic tonsillitis" (OR: 2.00; 95% CI: 1.58-2.52), and "acute pharyngitis" (OR: 1.74; 95% CI: 1.50-2.03). SA similarly indicated the strongest associations with PTA for the prior diagnoses of "acute tonsillitis" (OR: 5.02; 95% CI: 4.60-5.47), "chronic tonsillitis" (OR: 1.87; 95% CI: 1.64-2.12), and "acute pharyngitis" (OR: 1.27; 95% CI: 1.14-1.41). CONCLUSION: The most prevalent prior diagnosis associated with PTA was acute tonsillitis, followed by chronic tonsillitis and acute pharyngitis. The association with acute pharyngitis suggests possible non-tonsillogenic causes. Other specific causes of PTA, such as inflammation of the palatine gland or branchiogenic remnants, are not captured by the ICD system or the database utilized in this study.

Therapeutic management of peritonsillar abscess during COVID-19.

PURPOSE: The purpose of this study is to examine the effects of the Covid-19 pandemic and lockdown policies in Germany on frequency and treatment of peritonsillar abscess at a tertiary referral center in Germany. METHODS: This retrospective case-control study analyzed all cases of peritonsillar abscess treated from 03/01/2018 until 08/30/2022 at Augsburg ENT University Hospital, Germany, through abscess tonsillectomy and/ or incisional drainage. Data was collected and correlated to Covid-19 Stringency Index using codes based on the Institute for Hospital Remuneration System in Germany. After excluding 303 cases, 975 abscess tonsillectomy and incisional drainage cases were studied, with the first German lockdown serving as cutoff date. Treatment algorithm was maintained regardless of co-infection with Covid-19. RESULTS: A total of 174 patients received abscess tonsillectomy as therapy, while 801 patients underwent incisional drainage. Before the first German lockdown, 452 patients received incisional drainage. Since the pandemic, 349 cases of incisional drainage were registered (OR = 0.54, 95%-CI [0.27-0.86], p = 0.04), despite no significant change in the percentage of peritonsillar abscess of all ENT emergencies. The mean age at presentation with PTA was 39.8 years, and the rate of relapse was 4.0%. The study found no association between the scale of policy measures and treatment (OR = 1.00, 95%-CI [0.99-1.01], p = 0.52). CONCLUSION: The results indicate that, despite the reduction in capacities due to Covid-19, the proportion of patients with peritonsillar abscess treated through abscess tonsillectomy increased at Augsburg ENT University Hospital since the first German lockdown. Hospitalization times could still be reduced with comparable relapse rates.

Low usefulness of reporting tonsillar PCR Ct-values in pharyngeal infections with Fusobacterium necrophorum.

Tonsillar Fusobacterium necrophorum PCR Ct-values were higher in participants with asymptomatic tonsillar carriage than patients with pharyngeal infections. However, Ct-values were not associated with severity of disease or predictive of development of complications and hence lacked clinical usefulness. The reporting of F. necrophorum Ct-values in clinical samples is not recommended.

Impact of the COVID-19 era on clinical presentation, management and microbiology in paediatric peritonsillar abscess: A case-control study.

OBJECTIVES: Peritonsillar abscess (PTA) is the most common soft-tissue infection of the head and neck. This potential complication of tonsillitis has demonstrated unique microbial trends during the COVID-19 pandemic. This era has resulted in a major shift in the hygiene and social habits of the general population, which has resulted in changes in the presentation, management and microbiology of several infectious diseases. To date, the impact of COVID 19 on PTA microbiology and clinical presentation in the paediatric population has yet to be investigated. DESIGN: Retrospective chart review comparing all cases of paediatric (age 0-18) PTA in an academic tertiary centre during the COVID-19 pandemic (03/2020-02/2022) and compared them to two control groups: pre-COVID (03/2018-02/2020) and post-COVID (03/2022-03/2023). All patients were treated with either needle aspiration, incision and drainage or both means in addition to intravenous antibiotics. SETTING: A large Ear Nose and Throat department in a tertiary referral center. PARTICIPANTS: Consecutive children aged 18 years or under, admitted with a diagnosis of Peritonsillar abscess. MAIN OUTCOME MEASURES: We analyzed the clinical and microbiologcal features of all cases of pediatric peritonsillar abscess during the COVID-19 era (03/2020-02/2022) and compared them to a pre and post control cases. RESULTS: A total of 96 PTA cases were included (35 pre-COVID, 35 COVID and 26 post-COVID). The means of procedural treatment shifted in favour of incision and drainage versus needle aspiration during the COVID era. The length of hospitalisation increased during the COVID era (3.6 days vs. 2.1 and 3.1 pre and post-COVID respectively, p < .001). No other notable differences in the clinical and demographic features were found between the three eras. The COVID-19 era saw an increase in Fusobacterium (37.1% vs. 8.6% and 24% pre and post-COVID, respectively; p = .008) and Streptococcus Anginosus (31.4% vs. 5.7% and 7.7% pre and post-COVID, respectively; p = .007) species isolation. CONCLUSIONS: The COVID-19 pandemic did not seem to impact the clinical presentation of paediatric PTA yet resulted in a change in microbiological pathogens. The choice of I&D as a means to shorten hospital stay during the pandemic may have led to an actual increase in hospital stay, suggesting that NA may be the preferred management approach.

[Ultrasonography for peritonsillar abscess diagnosis: benefits and drawbacks]. / Ul'trazvukovaya diagnostika paratonzillyarnogo abstsessa: preimushchestva i nedostatki.

In 2 clinical cases the neck soft tissues ultrasound in the young and old patients allowed to solve the main diagnostic tasks: to determine the presence of peritonsillar abscess cavities, their sizes and localization; to exclude the fit of large vessels near to abscesses and the presence of abnormal vessels; to conduct differential diagnosis of abscesses from a tumor and allergic angioedema. Ultrasound with external access did not require any special preparation, was easily tolerated by the patient, was informative, but it was difficult to determine the puncture place. Intraoral ultrasound was more difficult to conduct, because the transducer should be small in size to enter the patient's mouth. If the patient had a pronounced trismus, intraoral ultrasound couldn't be done. On the one hand in a case of children use the standard transducer cannot fit in the mouth as well and may be damaged by teeth. But on the other hand, the abscess puncture site can be more easily determined by intraoral examination. Compared to multi-slice computed tomography with contrast, the ultrasound method is cheaper, more accessible, faster, more informative and there is no radiation exposure associated with this method. CONCLUSION: Ultrasound of the peritonsillar region by external and intraoral methods is informative for detecting peritonsillar abscess, especially in difficult diagnostic cases.

Unveiling the etiology of peritonsillar abscess using next generation sequencing.

BACKGROUND: Peritonsillar abscess (PTA) is a severe deep neck space infection with an insufficiently characterized bacterial etiology. We aimed to reveal the bacteria associated with PTA applying next generation sequencing (NGS). Tonsil biopsies and pus samples of 91 PTA patients were analysed applying NGS method. RESULTS: Over 400 genera and 800 species belonging to 34 phyla were revealed. The most abundant species in both sample types were Streptococcus pyogenes, Fusobacterium necrophorum and Fusobacterium nucleatum. When present, S. pyogenes was normally a predominant species, although it was recovered as a minor population in some samples dominated by F. nucleatum and occasionally F. necrophorum. S. pyogenes and F. necrophorum were the predominant species (> 10% in a community) in 28 (31%) pus samples, while F. nucleatum in 21 (23%) and S. anginosus in 8 (9%) pus samples. We observed no substantial differences between the microbial findings in pus and tonsil biopsies. CONCLUSIONS: The most probable causative agents of PTA according to our NGS-study include Streptococcus pyogenes, Fusobacterium necrophorum and Fusobacterium nucleatum. Some other streptococci (S. anginosus) and anaerobes (Prevotella, Porphyromonas) may contribute to the infection as well. Pus of the peritonsillar abscess is more representative specimen for microbiological examination than the tonsillar tissue. Our results are important in the context of optimizing the handling of the PTA patients.

Treatments and outcomes of adult parapharyngeal and retropharyngeal abscess: 1882 cases from a Japanese nationwide database.

PURPOSE: Although parapharyngeal and retropharyngeal abscesses are potentially fatal deep neck abscesses, there is limited evidence for the treatment courses for adult patients with these abscesses. We aimed to describe the practice patterns and clinical outcomes of adult patients undergoing an emergency surgery for parapharyngeal or retropharyngeal abscesses using a nationwide database. MATERIALS AND METHODS: We identified patients aged ≥18 years who underwent emergency surgery for parapharyngeal (para group, n = 1148) or retropharyngeal (retro group, n = 734) abscesses from July 2010 to March 2020, using a nationwide inpatient database. We performed between-group comparisons of the baseline characteristics, treatment course, and outcomes. RESULTS: Compared with the retro group, the para group was more likely to be older (median, 66 vs. 60 years; P < 0.001) and have several comorbidities, such as diabetes (21 % vs 16 %; P = 0.010) and epiglottitis (33 % vs. 26 %; P = 0.002), except for peritonsillar abscess (14 % vs. 22 %; P < 0.001) and tonsillitis (2.1 % vs. 13 %; P < 0.001). Regarding intravenous drugs administered within 2 days of admission, approximately half of the patients received steroids, non-antipseudomonal penicillins, and lincomycins. The para group received more comprehensive treatments, such as tracheostomy, intensive care unit admissions, and swallowing rehabilitation, within total hospitalization than the retro group. Moreover, it demonstrated higher in-hospital mortality (2.7 % vs. 1.1 %; P = 0.017) and morbidity (16 % vs. 9.7 %; P < 0.001), and longer length of hospitalization than the retro group. CONCLUSION: The current nationwide study provided an overview of the characteristics, treatments, and outcomes for patients who underwent an emergency surgery for parapharyngeal or retropharyngeal abscess.

Acute Tonsillitis Due To Monkeypox.

BACKGROUND: The emerging 2022 human mpox virus outbreak has presented with unique disease manifestations challenging prior case definitions. CASE REPORT: We present a case of a 42-year-old transgender woman with human immunodeficiency virus controlled on antiretroviral therapy, presenting with sore throat, who, after three emergency department visits, was found to have acute tonsillitis complicated by airway obstruction secondary to mpox. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Sore throat is a common presentation to the emergency department. mpox should be placed on the list of differential diagnoses when evaluating patients who present with pharyngitis to avoid complications or a missed diagnosis.

Use of Needle Guide for Dynamic Real-Time Ultrasound-Directed Aspiration of Peritonsillar Abscess in the Emergency Department: A Case Series.

BACKGROUND: Needle aspiration is a common treatment of peritonsillar abscess (PTA). Point-of-care ultrasound (POCUS) can be used to guide this procedure. We describe our experience using a commercially available needle guide attached to an endocavitary ultrasound probe for dynamic real-time POCUS-guided PTA needle aspiration. DISCUSSION: A convenience sample of patients were treated using the needle guide. The primary author (Peter Kumasaka) performed or supervised emergency medicine residents and physician assistants (PAs) for each case in which the needle guide was used. The electronic medical records were abstracted for procedure success, various length of stay (LOS) data, and to determine use of computed tomography imaging and otorhinolaryngologist (ENT) consultation. Dynamic POCUS-guided needle aspiration using the needle guide (DNG) was performed on 8 patients. There were no unexpected return visits to the emergency department (ED) or to the ENT clinic for any of the patients. The median time to perform DNG was 9 min (range 8-17 min). Median LOS was 182 min (range 78-287 min). Median time from POCUS order to patient discharge was 82.5 min (range 66-237 min). Median time from starting procedure to discharge was 43 min (range 18-148 min). CONCLUSIONS: The needle guide is a useful adjunct to assist in PTA drainage. It provided rapid, safe, and efficient care. Additional research is needed to see how this technique compares with more traditional methods of PTA drainage.

Immediate or interval abscess tonsillectomy? A systematic review and meta-analysis.

OBJECTIVES: Peritonsillar abscess is a common complication of acute tonsillitis. However, no consensus has been reached yet on the optimal treatment of this condition. Therefore, this study aimed to compare clinical outcomes of immediate and interval abscess tonsillectomy. METHODS: The databases of PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for completed studies published until the 1st of November 2021. Comparative studies assessing intraoperative and postoperative outcomes of immediate and interval abscess tonsillectomy were considered, with the primary outcome being postoperative hemorrhage. Operative time, intraoperative blood loss, postoperative pain, and duration of hospital stay were classed as secondary outcomes. A random-effects pairwise meta-analysis of both randomized and non-randomized trials was conducted. Subgroup analysis linked to the randomization of trials was executed. Quality assessment was performed, utilizing the Cochrane risk of bias tool and ROBINS-I tool for randomized and non-randomized trials, respectively. RESULTS: Data from 265 cases stemming from six trials were pooled together. For postoperative bleeding rates, no statistically significant difference between immediate and interval tonsillectomy was detected (OR = 1.26; 95% CI 0.27, 5.86; p = 0.77). By contrast, longer hospital stay was observed for patients subjected to interval tonsillectomy (SMD = - 0.78; CI - 1.39 to- 0.17; p = 0.01). For operative time and intraoperative blood loss, no statistically significant difference was noticed between immediate and interval tonsillectomy (SMD = 1.10; 95% CI - 0.13, 2.33; p = 0.08; and SMD = 0.04; 95% CI - 0.49, 0.57; p = 0.88; respectively). CONCLUSIONS: This study shows that quinsy tonsillectomy appears to be a safe method, providing full abscess drainage and instant relief of the symptoms. Moreover, quinsy tonsillectomy was not associated with a statistically higher postoperative hemorrhage incidence rate than immediate tonsillectomy.

Impact of the COVID-pandemic on the incidence of tonsil surgery and sore throat in Germany.

PURPOSE: To longitudinally evaluate the impact of the COVID-19-pandemic on the incidence of inpatient tonsil surgery and outpatient primary care of sore throat in Germany. METHODS: A retrospective interrupted time-series analysis was conducted. The national database of the Hospital Remuneration System was used to retrieve the number of operations performed between January 2019 and September 2021 including elective and non-elective cases with the exception of malign diseases. Three episodes were compared on a weekly basis: before, during, and after the first national lockdown (March 16-May 3, 2020). We also analysed the number of outpatient doctor contacts of sore throat patients in 2019 and 2020. RESULTS: Overall, 144,069 surgical cases were included in the analysis. The first lockdown resulted in an abrupt and significant decrease of all types of tonsil surgery (p < 0.01). The incidence of tonsillectomy decreased from 556 (before) to 111 (during) and 326 (after) cases per week (relative risk 0.24; 95% CI 0.19-0.30, and 0.82; 95% CI 0.73-0.92). After the lockdown, the incidence persisted on a lower level compared to 2019. The number of doctor contacts decreased from 2,967,322 in 2019 to 1,976,617 in 2020 (- 33.4%). CONCLUSIONS: The first lockdown was associated with a significant decrease of all types of tonsil surgery. A return to pre-pandemic surgical activity was not identified. The findings were accompanied by a significant decrease of outpatient doctor contacts of sore throat patients in primary care, particularly in the subgroup of children and adolescents. The impact of the second lockdown, starting in December 2020, was by far not comparable.

Fusobacterium necrophorum oral infections - A need for guidance.

F. necrophorum, a gram-negative obligate anaerobe, causes pharyngotonsillitis, peritonsillar abscess and the Lemierre Syndrome as well as other significant infections. Clinical information on this bacterium has increased dramatically over the past 20 years, yet no standard guidance exists for treating these infections. While data support F. necrophorum as a cause of pharyngotonsillitis, no consensus exists on the clinical importance of these findings especially in the 15-30 age group. Similarly, recent data find this bacterium the most frequent and most likely to recur in peritonsillar abscess for that age group. Should this impact how we treat these patients? Finally, we have no studies of either antibiotics or anticoagulation for the Lemierre Syndrome. Thus, each physician making the diagnosis of the Lemierre Syndrome chooses antibiotics (and their duration) and whether or not to anticoagulate without guidance. Infectious disease specialists and hospitalists would benefit from consensus expert opinions based on reviewing data on these infections.

Analysis of Microorganism Colonization, Biofilm Production, and Antibacterial Susceptibility in Recurrent Tonsillitis and Peritonsillar Abscess Patients.

Background: Despite the widespread use of antibiotics to treat infected tonsils, episodes of tonsillitis tend to recur and turn into recurrent tonsillitis (RT) or are complicated by peritonsillar abscesses (PTAs). The treatment of RT and PTAs remains surgical, and tonsillectomies are still relevant. Materials and methods: In a prospective, controlled study, we analyzed the bacteria of the tonsillar crypts of 99 patients with RT and 29 patients with a PTA. We performed the biofilm formation and antibacterial susceptibility testing of strains isolated from study patients. We compared the results obtained between patient groups with the aim to identify any differences that may contribute to ongoing symptoms of RT or that may play a role in developing PTAs. Results: The greatest diversity of microorganisms was found in patients with RT. Gram-positive bacteria were predominant in both groups. Candida species were predominant in patients with a PTA (48.3% of cases). Irrespective of patient group, the most commonly isolated pathogenic bacterium was S. aureus (in 33.3% of RT cases and in 24.14% of PTA cases). The most prevalent Gram-negative bacterium was K. pneumoniae (in 10.1% of RT cases and in 13.4% of PTA cases). At least one biofilm-producing strain was found in 37.4% of RT cases and in 27.6% of PTA cases. Moderate or strong biofilm producers were detected in 16 out of 37 cases of RT and in 2 out of 8 PTA cases. There was a statistically significant association found between the presence of Gram-positive bacteria and a biofilm-formation phenotype in the RT group and PTA group (Pearson χ2 test, p < 0.001). S. aureus and K. pneumoniae strains were sensitive to commonly used antibiotics. One S. aureus isolate was identified as MRSA. Conclusions: S. aureus is the most common pathogen isolated from patients with RT, and Candida spp. are the most common pathogens isolated from patients with a PTA. S. aureus isolates are susceptible to most antibiotics. Patients with RT more commonly have biofilm-producing strains, but patients with a PTA more commonly have biofilm non-producer strains. K. pneumoniae does not play a major role in biofilm production.

[Typical emergencies in otorhinolaryngology-a monocentric analysis of the seasonal course]. / Typische Notfälle in der Hals-Nasen-Ohren-Heilkunde ­ eine monozentrische Evaluation über den jahreszeitlichen Verlauf.

BACKGROUND: The incidence of acute ear, nose, and throat (ENT) diagnoses is influenced by multiple parameters, for example meteorological and seasonal influences. By better understanding the triggering factors, prophylactic approaches can be developed. MATERIALS AND METHODS: A retrospective analysis was performed over 6 years of all patients who presented to the university hospital because of typical and minor ENT emergencies. The diagnoses impacted cerumen, acute otitis media, acute otitis externa, nasal bone fracture, epistaxis, acute tonsillitis, acute rhinosinusitis, and peritonsillar abscess were analyzed. RESULTS: A total of 32,968 cases were analyzed. Epistaxis was the most common of the investigated emergency diagnoses, accounting for 24.5% (8082 cases). Epistaxis, acute otitis media, and acute rhinosinusitis occurred significantly more frequently in the colder half of the year. There was no significant correlation of the incidence of nasal bone fracture with public holidays. Acute otitis externa correlated significantly with the local summer vacations. In calendar week 38, the fewest total emergency presentations occurred, whereas in calendar week 52, the most emergency presentations occurred. CONCLUSION: Seasonal and meteorological factors play a significant role in the pathogenesis of many emergency ENT diagnoses.

Quality of Life Assessment for Tonsillar Infections and Their Treatment.

Background and Objectives: Tonsillar infections are a common reason to see a physician and lead to a reduction in the patients' health-related quality of life (HRQoL). HRQoL may be an important criterion in decision science and should be taken into account when deciding when to perform tonsillectomy, especially for chronic tonsillitis. The aim of this study was to determine the health utility for different states of tonsillar infections. Materials and Methods: Hospitalized patients with acute tonsillitis or a peritonsillar abscess were asked about their HRQoL with the 15D questionnaire. Patients who had undergone tonsillectomy were reassessed six months postoperatively. Results: In total, 65 patients participated in the study. The health states of acute tonsillitis and peritonsillar abscess had both a utility of 0.72. Six months after tonsillectomy, the mean health utility was 0.95. Conclusions: Our study confirms a substantial reduction in utility due to tonsillar infections. Tonsillectomy significantly improves the utility and therefore HRQoL six months after surgery.

Utility of CT in the workup of adults with sore throat in the emergency department.

OBJECTIVE: The goal of this study was to determine if computed tomography (CT) added any clinical information that was incorporated into the decision regarding treatment for patients who presented to the Emergency Department (ED) with sore throat. METHODS: A retrospective chart review of adult patients who presented to the ED with a chief complaint of sore throat who subsequently underwent CT during that ED visit between 1/1/18 and 12/31/18 at our tertiary academic health center was performed. The association between palatal bulge on Otolaryngology physical exam with successful drainage procedure was examined. The mean Hounsfield units (HU) and maximum dimension of measurable fluid collection on CT were compared between patients who underwent a successful drainage procedure and those who did not undergo a drainage procedure or attempted drainage was unsuccessful. RESULTS: Ninety-four patients met inclusion criteria, with 53% (50/94) men. Of the 22 patients with a palatal bulge on physical examination by Otolaryngology, 86% (19/22) underwent a successful drainage procedure (p < 0.001) when compared to those not undergoing successful drainage. Notably, 56% (53/94) of CT scans were interpreted as normal or tonsillitis. The mean HU was 42.0 in those patients who underwent a successful drainage procedure and 74.1 in those who did not undergo a drainage procedure (p < 0.001). Overall, 21/35 fluid collections had a palatal bulge (p < 0.001). CONCLUSION: Palatal bulge is a reliable finding in identifying patients with a drainable peritonsillar abscess, and CT scans could largely be avoided in patients without physical exam findings suggestive of more extensive deep neck space abscesses. If a CT scan is obtained, HU should be measured and incorporated into the shared decision-making process with the patient.

Empiric treatment for peritonsillar abscess: A single-center experience with medical therapy alone.

PURPOSE: Compare the use of medical therapy alone (MTA) with surgical therapy (ST) for the empiric treatment of peritonsillar abscess (PTA). MATERIALS AND METHODS: A consecutive cohort of patients treated for PTA at our institution from May 2013 to February 2019 was analyzed. Demographics, disease characteristics, management strategies, and treatment outcomes were compared between treatment groups. Primary outcomes included treatment failure, defined as the need for follow-up surgical intervention, and complications within 2-weeks of empiric treatment. RESULTS: 306 patients (72.7%) received MTA while 115 (27.3%) underwent ST. There was no significant difference in the rate of treatment failure between the MTA (7.2%) and ST (6.1%) groups (p = 0.879). Complications were rare in both groups (1.6% with MTA versus 0.9% with ST; p = 0.898). Dysphagia (p = 0.011), trismus (p = 0.045), larger abscesses (p < 0.001), and hospital admission (p < 0.001) were more common in the ST group. Corticosteroid prescriptions were a common component of MTA (53.3%) and less often used with ST (33.9%; p = 0.001). After adjusting for abscess size, there remained no significant difference in the rate of treatment failure between groups. Univariate analyses demonstrated no significant independent predictors of treatment failure including age, sex, race, tonsillitis history, smoking history, presenting signs and symptoms, abscess size, hospital admission, and corticosteroid prescriptions. CONCLUSIONS: MTA may be a safe and effective alternative to surgical drainage for the empiric treatment of PTA, warranting larger-scale prospective analyses. Abscess size did not appear to influence treatment failure; however, careful patient selection is likely to optimize treatment outcomes.

A 4-year retrospective study of tonsillectomy rate and admission rate of tonsillitis and complications in the East of England and nationally.

OBJECTIVES: Guidance set out by Scottish Intercollegiate Guidelines Network (SIGN) sought to restrict the frequency of elective tonsillectomy in reaction to the recognised and substantial risks of the procedure, namely pain and bleeding. With stricter criteria in place before a patient can undergo tonsillectomy, patients must endure more episodes of tonsillitis than was previously the case. The cost of managing tonsillitis and its complications as an inpatient is substantial to the NHS and also to the economy as a whole in missed work days. The authors sought to establish if the reduced rate of tonsillectomy performed had any effect on the rate of acute hospital admission for tonsillitis or the associated abscesses-peritonsillar, parapharyngeal and retropharyngeal. METHODS: A retrospective multi-centre study reviewed admission data across a 4-year period. The rate of tonsillectomies performed for recurrent tonsillitis across four trusts in Mid-Essex was compared with the number of admissions for tonsillitis, peritonsillar, parapharyngeal and retropharyngeal abscesses. National hospital episode statistics data over a 5-year period was also analysed. RESULTS: For the regional data in 2015, 979 tonsillectomies were performed across the four centres, reducing to 875 in 2018. There was no trend in the rates of acute tonsillitis requiring admission but the rates of peritonsillar abscess increased from 156 to 192 cases per year in the same period. This correlation was found not to be statistically significant in the measured sample size. The National hospital episode statistics data showed a significant correlation between tonsillectomy rates and admissions from complications of tonsillitis as well as the associated abscesses. CONCLUSION: This study shows that the reduced tonsillectomy rate was correlated with an increased number of admissions with peritonsillar abscess regionally. Nationally reduced tonsillectomy rate is significantly associated with increased admissions with tonsillitis and all its complications. A decreased rate of tonsillectomy may be increasing the rate of serious tonsillitis. This has an impact on patient morbidity, an increasing financial burden on the NHS and the UK economy.
