Abstract
BACKGROUND The number of unexpected focal [18F]FDG-avid findings (incidentalomas) within the parotid gland (PGI) continues to increase with the expanding use of PET/CT scanning. The prevalence of malignancy in PGIs is uncertain and appropriate management is unsettled. AIMS We aimed to explore the underlying pathologies associated with PGI. MATERIALS AND METHODS A retrospective review of all patients with parotid gland incidentaloma(s) treated at the Ear-Nose-Throat Department, Aarhus University Hospital, Denmark in the period 2012-2021, was performed. RESULTS In total, 94 patients with one (n = 86) or two (n = 8) PGI(s) were included. In patients with one PGI, 72 (84%) focuses were benign, two (2%) focuses were malignant (both malignant melanoma metastases), and 12 (14%) focuses were undiagnosed. In patients with two PGIs, all 12 lesions with pathological examinations were benign (4 PGIs were undiagnosed). The median SUVmax found in benign lesions was higher (12.0) compared to malignant lesions (5.5) (p = .043). CONCLUSIONS AND SIGNIFICANCE The prevalence of malignancy was low (2/94, 2.4%) in PGIs. Based on our findings, PGI in patients without a history of parotid malignancy, who undergo PET/CT scanning for reasons other than head and neck cancer (including malignant melanoma), may be managed similarly to patients with asymptomatic parotid gland tumors.

Abstract
OBJECTIVES We aimed to explore the impact of social distancing on the incidence and microbiology of peritonsillar abscess (PTA). METHODS We performed a cross-sectional analysis of all patients with PTA and their microbiological findings in the 2 years preceding versus the 2 years following the COVID-19 lockdown in Denmark (11 March 2020), who were admitted to the Ear-Nose-Throat Department, Aarhus University Hospital. Age-stratified population data for the catchment area were obtained from Statistics Denmark. RESULTS The annual incidence rate was significantly higher in the 2-year period before (21.8 cases/100 000 inhabitants) compared with after (14.9 cases/100 000) the lockdown (p < 0.001). The number of cases with growth of Streptococcus pyogenes was significantly higher in the period before (n = 67) compared with after (n = 28) the lockdown (p < 0.001), whereas the number of cases positive for Fusobacterium necrophorum (n = 60 vs. n = 64) and streptococcus anginosus group (SAG) (n = 37 vs. n = 43) were stabile (p 0.79 and p 0.58, respectively). The relative prevalence of S. pyogenes was significantly higher in the period before (67/246 cultures, 27%) compared with after (28/179, 16%) the lockdown (p 0.007). On the contrary, the relative prevalence of F. necrophorum and SAG is significantly lower before (60/246, 24% and 37/246, 15%) compared with after (64/179, 36% and 43/179, 24%) the lockdown (p 0.013 and p 0.023). DISCUSSION Social distancing had a significant impact on the incidence and microbiology of PTA. Our findings suggest that S. pyogenes-positive PTA is highly related to direct social interaction, and represents a contagious pathogen. By contrast, PTA development caused by F. necrophorum and SAG is unrelated to direct social interaction and may be derived from flora imbalance.

Abstract
OBJECTIVES The criteria for selecting patients with recurrent acute tonsillitis (RT) for tonsillectomy remain unsettled and different guidelines are used internationally. We aimed to evaluate currently used guidelines for tonsillectomy in adults with RT and identify the best predictive parameters for improved throat-related quality of life (TR-QOL) after surgery. METHODS About 66 RT patients undergoing tonsillectomy was prospectively included and categorized into 3 groups based on which guideline(s) they met: Group 1: patients not meeting any of the Danish/Paradise/Scottish Intercollegiate Guideline Network (SIGN) guidelines. Group 2: patients meeting the Danish guidelines. Group 3: patients meeting the Paradise and/or the SIGN guidelines. TR-QOL was assessed using the Tonsillectomy Outcome Inventory 14 (TOI-14) before and 6 months after tonsillectomy as well as the Glasgow Benefit Inventory (GBI). Predictive parameters for improved TR-QOL were investigated using multiple linear regression. RESULTS About 61 (92%) patients completed the questionnaires. Patients in all groups had significant TR-QOL improvements (Group 1 (n = 20): ΔTOI-14 31.1; GBI 29.4; Group 2 (n = 31): ΔTOI-14 32.0; GBI 36.4; Group 3 (n = 10): ΔTOI-14 45.6; GBI 39.7) and satisfaction rates were high (94%-100%). Preoperative TOI-14 score was the best predictor for improved TR-QOL (P < .001, R2 = .80), followed by the number of tonsillitis episodes with physician verification within the previous 12 months (P = .002, R2 = .25). CONCLUSIONS Patients in all groups experienced massive TR-QOL improvements suggesting that currently used guidelines may be too restrictive. Preoperative TOI-14 score was the best parameter for predicting TR-QOL improvement, and this tool may be useful in the selection of adults with RT for tonsillectomy.

Abstract
BACKGROUND The vast majority of patients with acute tonsillitis (AT) are managed in general practice. However, occasionally patients are referred to hospital for specialized management because of aggravated symptoms and/or findings suggestive of peritonsillar involvement. No prospective studies have been conducted aiming to investigate the prevalent and significant microorganisms in this highly selected group of patients. We aimed to describe the microbiological findings of acute tonsillitis with or without peritonsillar phlegmon (PP) in patients referred for hospital treatment and to point out potential pathogens using the following principles to suggest pathogenic significance: (1) higher prevalence in patients compared to healthy controls, (2) higher abundance in patients compared to controls, and (3) higher prevalence at time of infection compared to time of follow up. METHODS Meticulous and comprehensive cultures were performed on tonsillar swabs from 64 patients with AT with (n = 25) or without (n = 39) PP and 55 healthy controls, who were prospectively enrolled at two Danish Ear-Nose-Throat Departments between June 2016 and December 2019. RESULTS Streptococcus pyogenes was significantly more prevalent in patients (27%) compared to controls (4%) (p < 0.001). Higher abundance was found in patients compared to controls for Fusobacterium necrophorum (mean 2.4 vs. 1.4, p = 0.017) and S. pyogenes (mean 3.1 vs. 2.0, p = 0.045) in semi-quantitative cultures. S. pyogenes, Streptococcus dysgalactiae, and Prevotella species were significantly more prevalent at time of infection compared to follow up (p = 0.016, p = 0.016, and p = 0.039, respectively). A number of species were detected significantly less frequently in patients compared to controls and the mean number of species was significantly lower in patients compared to controls (6.5 vs. 8.3, p < 0.001). CONCLUSIONS Disregarding Prevotella spp. because of the prevalence in healthy controls (100%), our findings suggest that S. pyogenes, F. necrophorum, and S. dysgalactiae are significant pathogens in severe AT with or without PP. In addition, infections were associated with reduced diversity (dysbacteriosis). TRIAL REGISTRATION The study is registered in the ClinicalTrials.gov protocol database (# 52,683). The study was approved by the Ethical Committee at Aarhus County (# 1-10-72-71-16) and by the Danish Data Protection Agency (# 1-16-02-65-16).

Abstract
INTRODUCTION No Danish validated patient-reported outcome measure (PROM) exises for assessing throat-related quality of life in patients with recurrent acute tonsillitis (RT) and chronic tonsillitis (CT). We aimed to translate and linguistically validate the Tonsillectomy Outcome Inventory 14 (TOI-14) into Danish and describe scores in RT and CT patients before and after tonsillectomy as well as in healthy controls. METHODS We followed the guideline for PROM translation and cultural adaption set out by the Quality of Life Special Interest Group - Translation and Cultural Adaptation group formed by ISPOR. We included RT and CT patients undergoing elective tonsillectomy, who answered the questionnaire pre- and post-operatively (six-month follow-up) as well as healthy controls who answered the questionnaire once. RESULTS A Danish version of the TOI-14 was developed according to the guideline. A total of 49 RT patients, 34 CT patients and 67 controls were included in the final analysis. Preoperatively, RT and CT patients had markedly higher TOI-14 scores than controls (mean total scores: RT: 45.6; CT: 21.7; controls: 8.9, both p less-than 0.001). Post-operatively, scores fell to levels similar to those of controls (RT: 10.2, p = 0.51; CT: 4.7, p = 0.05). CONCLUSION We translated, culturally adapted and linguistically validated the Danish version of the TOI-14, finding scores in RT patients, CT patients and controls similar to those recorded by previous studies in German, English and Finnish.

Abstract
PURPOSE The aim of this study is to present incidence, histological subtypes, survival rates, and prognostic factors based on a national cohort of patients with salivary gland carcinoma. METHODS All Danish patients with submandibular gland carcinoma diagnosed from 1990 to 2015 (n = 206) were included and analyzed following histological re-evaluation. Data were collected by the Danish Head and Neck Cancer Group (DAHANCA). Overall, disease-specific and recurrence-free survival were evaluated. Prognostic factors were analyzed with multivariate Cox Hazard Regression. RESULTS The study population consisted of 109 (53%) men and 97 (47%) women, median age 62 years (range 11-102). Adenoid cystic carcinoma was the most frequent subtype (50%). Tumour classification T1/T2 (75%) and N0 (78%) was most frequent. The mean crude incidence was 0.17/100,000/year. Most patients (n = 194, 94%) were treated with primary surgery, and 130 (67%) received postoperative radiotherapy. The 5- and 10-year survival rates were for overall survival 64% and 41%, disease-specific survival 74% and 61%, and recurrence-free survival 70% and 56%, respectively. Survival rates were higher for adenoid cystic carcinoma compared to other subtypes, but the difference was not significant in multivariate analysis. Recurrence occurred in 69 patients, and 37 (53.6%) of them had recurrence in a distant site. Advanced T-classification and regional lymph-node metastases had significant negative impact on survival rates. CONCLUSION The incidence of submandibular gland carcinoma in Denmark was 0.17/100,000/year and stable during the time period. The most frequent subtype was adenoid cystic carcinoma. Half of the recurrences presented in a distant site, and multivariate analysis confirmed that advanced stage was independent negative prognostic factor for recurrence and survival.

Abstract
OBJECTIVES The management of incidental findings of FDG-avid tonsils on PET/CT (IFT) is unclear. We aimed to explore the prevalence of malignancy in IFT, identify risk factors for malignancy, and calculate optimal cutoffs of maximum standardized uptake values (SUVmax ) to discriminate between benign and malignant lesions. METHODS All patients who were tonsillectomized at our institution because of IFT from October 2011 to December 2020 were included. Patients undergoing PET/CT due to suspected tonsillar disease or cancer of unknown primary were excluded. RESULTS In total, 77 patients were included, of which 11 (14%) of them had IFT malignancy. Dysphagia (p = 0.019) and alcohol abuse (p = 0.035) were associated with malignancy. Absolute SUVmax cutoff (≥9: sensitivity 100%; specificity 53%) was superior to SUVmax side-to-side ratio (≥1.5: sensitivity 64%; specificity 70%) to discriminate between benign and malignant lesions. CONCLUSION We recommend tonsillectomy for patients with IFT displaying SUVmax ≥ 9.0, ratio ≥ 1.5, or symptoms or findings suggesting malignancy. LEVEL OF EVIDENCE 3 Laryngoscope, 132:2370-2378, 2022.

Abstract
PURPOSE The significant pathogens associated with paediatric cervical suppurative lymphadenitis (CSL) are unclarified, and there is a lack of clinical evaluations of antibiotic regimens in paediatric CSL. We aimed to (1) explore the bacterial findings and the associated primary sites of infection in paediatric cases of CSL and (2) evaluate the clinical outcomes in patients treated with different antibiotic regimens. METHODS All children (< 18 years) treated for non-mycobacterium CSL at the Department of Otorhinolaryngology, Aarhus University Hospital, from 2001 to 2018 were retrospectively evaluated. RESULTS Eighty-five patients were included in the study. The prevalent isolates were S. aureus (57%), S. pyogenes (17%), non-haemolytic streptococci (11%), and F. necrophorum (3%). The primary sites of infection were identified in 30 (35%) patients. The most common sites were the oropharynx (n = 15), the middle ear (n = 10), and the skin (n = 5). All patients were treated with surgical incision and antibiotics. No statistically significant differences were found between patients treated with antibiotics covering streptococci (n = 60) versus antibiotics covering streptococci and S. aureus (n = 25) in terms of duration of hospitalisation (median 4 vs 4 days, p = 0.26), altered antibiotic treatment because of insufficient clinical or biochemical progress (7% vs 12%, p = 0.41), and abscess recurrence (8% vs 12%, p = 0.69). CONCLUSION S. aureus was the predominant pathogen in paediatric CSL at all cervical levels, and even in cases with evidence of primary site infection not normally associated with S. aureus. We were unable to underscore the importance of antibiotic treatment covering S. aureus based on evaluation of the clinical outcomes.

Abstract
PURPOSE We aimed to evaluate the effectiveness of different antibiotic regimens for the treatment of parapharyngeal abscess (PPA) and characterize patients, who suffered potentially preventable complications (defined as death, abscess recurrence, spread of infection, or altered antibiotic treatment because of insufficient progress). METHODS Sixty adult patients with surgically verified PPA were prospectively enrolled at five Danish Ear-nose-throat departments. RESULTS Surgical treatment included internal incision (100%), external incision (13%), and tonsillectomy (88%). Patients were treated with penicillin G ± metronidazole (n = 39), cefuroxime ± metronidazole (n = 16), or other antibiotics (n = 5). Compared to penicillin-treated patients, cefuroxime-treated patients were hospitalized for longer (4.5 vs 3.0 days, p = 0.007), were more frequently admitted to intensive care (56 vs 15%, p = 0.006), underwent external incision more frequently (31 vs 5%, p = 0.018), and suffered more complications (50 vs 18%, p = 0.022), including re-operation because of abscess recurrence (44 vs 3%, p < 0.001). Nine patients suffered potentially preventable complications. These patients displayed significantly higher C-reactive protein levels, received antibiotics prior to admission more frequently, underwent external incision more commonly, and were admitted to intensive care more frequently compared to other patients. CONCLUSION The majority of patients with PPA were effectively managed by abscess incision, tonsillectomy, and penicillin G ± metronidazole. Cefuroxime-treated patients were more severely ill at time of admission and had worse outcome compared to penicillin-treated patients. We recommend penicillin G + metronidazole as standard treatment for patients with PPA, but in cases with more risk factors for potentially preventable complications, we recommend aggressive surgical and broadened antibiotic therapy, e.g. piperacillin-tazobactam.

Abstract
BACKGROUND The aim was to identify prognostic factors and test three prognostic scoring models that predicted the risk of recurrence in patients with parotid gland carcinoma. METHODS All Danish patients with parotid gland carcinoma, treated with curative intent, from 1990 to 2015 (n = 726) were included. Potential prognostic factors were evaluated using Cox regression and competing risk analyses. The concordance of each prognostic model was estimated using Harrel's C index. RESULTS The study population consisted of 344 men and 382 women, with a median age of 63 years. Age above 60 years, high grade histology, T3/T4 tumor, regional lymph node metastases, and involved surgical margins were all associated with a significant reduction in recurrence-free survival. The prognostic model that agreed best with actual outcomes had a C-index of 0.76. CONCLUSION Prognostic scoring models may improve individualized follow-up strategies after curatively intended treatment for patients with parotid gland carcinoma.

Abstract
BACKGROUND Elective neck dissection (END) in patients with salivary gland carcinoma is controversial and there are no universally accepted guidelines. METHODS Patients were identified from the Danish Head and Neck Cancer Group. Between 2006 and 2015, 259 patients with primary salivary gland carcinoma were treated with END. Variables potentially associated with regional metastases were analyzed using logistic regression. Neck recurrence-free survival was calculated using the Kaplan-Meier method. RESULTS Occult metastases were found in 36 of the patients treated with END (14%) and were particularly frequent among patients with T3/T4 tumors and high-grade histology tumors. In multivariate analyses, high-grade histology and vascular invasion were associated with occult metastases. CONCLUSION We recommend END of levels II and III for patients with high-grade or unknown histological grade tumors, and for T3/T4 tumors. Levels I, II, and III should be included in END in patients with submandibular, sublingual, or minor salivary gland carcinomas.

Abstract
We aimed to describe the microbiology of parapharyngeal abscess (PPA) and point out the likely pathogens using the following principles to suggest pathogenic significance: (1) frequent recovery, (2) abundant growth, (3) growth in relative abundance to other microorganisms, (4) percentage of the isolates recovered in both absolute and relative abundance, (5) more frequent recovery in PPA pus compared with tonsillar surface and tissue. Comprehensive bacterial cultures were performed on specimens obtained from adult patients (n = 60) with surgically verified PPA, who were prospectively enrolled at five Danish ear-nose-throat departments. The prevalent isolates (in PPA pus) were unspecified anaerobes (73%), non-hemolytic streptococci (67%), Streptococcus anginosus group (SAG) (40%), Corynebacterium spp. (25%), Neisseria spp. (23%), Fusobacterium spp. (22%), Fusobacterium necrophorum (17%), Prevotella spp. (12%), and Streptococcus pyogenes (10%). The bacteria most frequently isolated in heavy (maximum) growth were unspecified anaerobes (60%), SAG (40%), F. necrophorum (23%), and Prevotella spp. (17%). The predominant microorganisms (those found in highest relative abundance) were unspecified anaerobes (53%), SAG (28%), non-hemolytic streptococci (25%), F. necrophorum (15%), S. pyogenes (10%), and Prevotella spp. (10%). Four potential pathogens were found in both heavy growth and highest relative abundance in at least 50% of cases: F. necrophorum, Prevotella spp., SAG, and S. pyogenes. SAG, Prevotella spp., F. necrophorum, S. pyogenes, and Bacteroides spp. were recovered with the same or higher frequency from PPA pus compared with tonsillar tissue and surface. Our findings suggest that SAG, F. necrophorum, Prevotella, and S. pyogenes are significant pathogens in PPA development.

Abstract
Background The vast majority of patients with peritonsillar abscess (PTA) recover uneventfully on abscess drainage and antibiotic therapy. However, occasionally patient´s condition deteriorates as the infection spread in the upper airway mucosa, through cervical tissues, or hematogenously. The bacterial etiology of PTA is unclarified and the preferred antimicrobial regimen remains controversial. The current narrative review was carried out with an aim to (1) describe the spectrum of complications previously recognized in patients with peritonsillar abscess (PTA), (2) describe the bacterial findings in PTA-associated complications, and (3) describe the time relation between PTA and complications. Methods Systematic searches in the Medline and EMBASE databases were conducted and data on cases with PTA and one or more complications were elicited. Results Seventeen different complications of PTA were reported. The most frequently described complications were descending mediastinitis (n = 113), para- and retropharyngeal abscess (n = 96), necrotizing fasciitis (n = 38), and Lemierre´s syndrome (n = 35). Males constituted 70% of cases and 49% of patients were > 40 years of age. The overall mortality rate was 10%. The most prevalent bacteria were viridans group streptococci (n = 41, 25%), beta-hemolytic streptococci (n = 32, 20%), F. necrophorum (n = 21, 13%), S. aureus (n = 18, 11%), Prevotella species (n = 17, 10%), and Bacteroides species (n = 14, 9%). Simultaneous diagnosis of PTA and complication was more common (59%) than development of complication after PTA treatment (36%) or recognition of complication prior to PTA (6%). Conclusion Clinicians involved in the management of PTA patients should be aware of the wide range of complications, which may arise in association with PTA development. Especially males and patients > 40 years of age seem to be at an increased risk of complicated disease. In addition to Group A streptococci and F. necrophorum, the current findings suggest that viridans group streptococci, S. aureus, Prevotella, and Bacteroides may also play occasional roles in the development of PTA as well as spread of infection. Complications occasionally develop in PTA patients, who are treated with antibiotics and surgical drainage.

Abstract
Background: Head and neck sarcomas are rare and difficult to diagnose and manage.Aim: To describe a population of patients with head and neck sarcomas focusing on the effect of symptom duration and time to diagnosis on mortality and recurrence risk.Materials and methods: Fifty-one patients treated in our department between 1998-2013 were retrospectively included. Patient and tumour characteristics as well as dates of interest were obtained from sarcoma registries, charts and pathology records. The effect of symptom duration and time to diagnosis on mortality and risk of recurrence was tested by multivariate analysis.Results: There was a wide range in symptom duration (1-144 months, median 5) and time for diagnosis (0-234 days, median 14) without significant effect on overall mortality, disease-specific mortality or risk of recurrence. Chondrosarcomas in the larynx dominated among the patients with the longest diagnostic duration.Conclusion and significance: The diagnostic process is challenging and in some cases of extremely long duration without effect on mortality. The symptom duration and time to diagnosis in relation to mortality and risk of recurrence has not previously been described. Early biopsy, better imaging and advanced pathological techniques can hopefully speed up the diagnostic process and reduce morbidity and mortality.

Abstract
INTRODUCTION Acute salivary gland infections (ASI) have been associated with poor outcome in elderly and postoperative patients. Perioperative care and treatment of co-morbidities have improved considerably, but most of our knowledge regarding ASI dates back several decades. The aim of this study was to describe the microbiology and treatment of ASI in a large post-millennial cohort. METHODS All patients with ASI admitted to the Department of Otorhinolaryngology - Head and Neck Surgery, Aarhus University Hospital in the period from 2001 to 2017 were included. RESULTS In total, 157 patients with ASI were included. The parotid gland (PG) was affected in 89 (57%) cases and the submandibular gland (SMG) in 68 (43%) cases. The most prevalent bacterial findings were viridans streptococci (25 isolates) and Staphylococcus aureus (19 isolates). S. aureus was almost exclusively found in PG (17/19 cases). S. aureus-positive cases showed a significantly higher inflammatory response than other bacteria (C-reactive protein, p = 0.008 and absolute neutrophil count, p = 0.0108). CONCLUSIONS S. aureus is a significant pathogen in ASI and especially in PG cases. Other pathogens may play a role in the development of SMG infections. Based on the bacterial findings in this study, we recommend penicillinase-resistant penicillin as first-line treatment in ASI. FUNDING none Trial registration: not relevant. The Danish Data Protection Agency approved the project.

Abstract
Background: Bilateral quinsy tonsillectomy (QT) in patients with peritonsillar abscess (PTA) is associated with the risk of post-tonsillectomy haemorrhage (PTH) and current literature finds a significantly higher risk of PTH contralaterally to the quinsy.Aims: To determine the prevalence of PTH in a large cohort of patients undergoing QT, explore risk factors for PTH, describe our methods of treatment, and evaluate if contralateral haemorrhage is more common than ipsilateral haemorrhage.Materials & methods: All patients undergoing QT at Aarhus University Hospital in the period 2001-2017 were included in the study.Results: One hundred sixteen of 1671 (6.9%) QT patients were admitted with PTH. PTH patients were significantly more frequently males (66%) and infected with Streptococcus group A (GAS) (31%) compared to QT patients without PTH (53% and 18%, respectively) (p = .005 and p = .002, respectively). Haemostasis was obtained in general anaesthesia (n = 61) or local anaesthesia (n = 28) and stopped spontaneously in 25 patients. The side of PTH was not associated with the side of PTA (ipsilateral (n = 41), contralateral (n = 43), and bilateral PTH (n = 23), p = .93).Conclusions and significance: Our findings question if unilateral QT is preferable to bilateral QT when the PTA does not respond to conservative treatment, especially in males with GAS-positive PTA.

Abstract
INTRODUCTION The aim of this study was to develop and validate a patient-based questionnaire for the assessment of sore throat symptoms. The questionnaire can be used to quantify the effects of different treatments in patients with acute pharyngo-tonsillitis (APT). METHODS A 13-item questionnaire was constructed using a five-point Likert scale. Adult patients with APT consulting one of the participating general practitioners answered the survey. Healthy students served as controls. RESULTS A total of 77 sore throat patients and 103 healthy controls were included. Ten items had moderate to high (> 0.25) inter-item correlations and high mean scores (> 3.0) among patients and were included in the final tool, the Sore Throat Assessment Tool (STAT)-10. The patients' mean STAT-10 score was 36.5 (95% confidence interval (CI): 34.8-38.2) at the time of inclusion compared with 10.4 (95% CI: 10.2-10.6) for controls (p < 0.001). Cronbach´s alpha coefficient for the questionnaire was 0.87. The standard error of measurement was 2.99, the intraclass correlation 0.92 and the Spearman correlation test-retest reliability 0.87. The STAT-10 scores increased with Centor scores (p = 0.018). CONCLUSIONS The reliability and validity of the STAT-10 were very high. The STAT-10 is the first validated tool for measuring the intensity and duration of symptoms from the perspective of sore throat patients and for quantifying and comparing different treatment modalities in APT patients. FUNDING This study received funding from The Lundbeck Foundation (Grant #R185-2014-2482), Fonden for Lægevidenskabens Fremme, and Hans Skouby´s Fond. TRIAL REGISTRATION The study was approved by the Danish Data Protection Agency (2015-57-0002).

Abstract
INTRODUCTION It remains unclarified if bacterial co-infection is common in patients with infectious mononucleosis (IM) and acute tonsillitis and/or peritonsillar abscess (PTA). Recent studies suggest that Fusobacterium necrophorum is a prevalent pathogen in acute tonsillitis and PTA. We hypothesised that this anaerobe may play a significant role for the aggravated infection and the development of PTA among teenagers and young adults with IM. METHODS All patients with IM and clinical findings of acute tonsillitis or PTA admitted to our department in the 2001-2015 period were included in the study. RESULTS In total, 257 patients with IM and acute tonsillitis (n = 220) or PTA (n = 37) were included. Positive bacterial cultures were obtained in 28% of patients with AT and in 50% with PTA. The most prevalent bacterial findings were Group C/G streptococci (14%) among patients with acute tonsillitis and Staphylococcus aureus (22%) in patients with PTA. F. necrophorum was recovered in 9% and 2% of patients with acute tonsillitis and PTA, respectively. CONCLUSIONS We were unable to substantiate a prevalent role for F. necrophorum in patients with IM and acute tonsillitis/PTA. S. aureus may play a role in PTA development in patients IM. The majority of our findings did not support the use of antibiotics in patients with IM, even in this selected group of patients with severe symptoms and a high risk of PTA.

Abstract
BACKGROUND The national guideline for sore throat, endorsed by the Danish Society of General Medicine, recommends the use of the modified Centor score and streptococcal rapid antigen detection test to guide diagnosis and treatment of sore throat. The aim was to investigate Danish general practitioners (GPs) routine management of sore throat patients with a focus on the modalities used and adherence to the guideline. METHODS A cross-sectional study. GPs in the Central Denmark Region answered an online questionnaire in October 2017. The main outcome measure was modalities used in the management of sore throat patients. RESULTS In total, 266 of 500 (53%) GPs answered the survey. Ten percent of participants were adherent or almost adherent to the guideline, while 82% of GPs added one or more extra modalities (general clinical assessment (67%), biochemical parameters (48%), and throat swabs for bacterial culture (18%)) to differentiate viral and bacterial etiology. Sixty-five percent of participants used the Centor Score or modified Centor Score, 96% of GPs used a streptococcal rapid antigen detection test, and all GPs chose narrow-spectrum penicillin as the first-line antibiotic. The most common reasons for non-adherence to the guideline were greater confidence in the clinical assessment (39%), time pressure (33%), and difficulty recalling the guideline (19%). CONCLUSION Danish GPs rarely adhere to the recommended sore throat management guideline, but use various combinations of different modalities in the assessment of bacterial infection. This practice may increase antibiotic prescription rates.

Abstract
INTRODUCTION We aimed to investigate doctors' ad-herence to the local antibiotic guidelines for treatment of patients admitted with acute pharyngeal infections and to identify patient-related risk factors for non-adherence. METHODS All patients with acute tonsillitis, peritonsillar abscess (PTA), and parapharyngeal abscess admitted to the Ear-Nose-Throat Department, Aarhus University Hospital, in the 2001-2014 period were included in the study. RESULTS In total, 2,567 patients were hospitalised with acute pharyngeal infection. In non-allergic patients, penicillin was prescribed to 81%, either alone (48%) or in combination with metronidazole (33%). Macrolides (54%) and cefuroxime (44%) were the drugs of choice in 85 (98%) patients who were allergic to penicillin. Patients were prescribed antibiotics according to guidelines in 63% of cases. The addition of metronidazole to penicillin was the main (75% of cases) reason for non-adherence. Increasing patient age and male gender were independent risk factors for non-adherence. PTA patients treated according to the guidelines had a significantly shorter hospital stay than patients treated with additional metronidazole or broad-spectrum antibiotics. CONCLUSIONS A significant (37%) proportion of patients with acute pharyngeal infections were treated non-adherently to antibiotic guidelines, mainly because of (inappropriate) addition of metronidazole to penicillin.

Abstract
The purpose was to determine the current evidence for preferable antibiotic treatment in three common clinical situations with insufficient consensus: Q1: Can antibiotic treatment prevent future attacks of acute pharyngo-tonsillitis (APT) in patients with recurrent APT (RAPT)? Q2: Which antibiotic regimen is preferable in the treatment of APT in patients with RAPT? Q3: Which antibiotic regimen is preferable in the treatment of relapsing APT? Five databases were searched systematically for randomized clinical trials on patients with RAPT with or without current APT or with relapse of APT. Of the unique publications, 643 were found. Five studies addressing Q1 (n = 3) and Q2 (n = 2) met the eligibility criteria. No studies reporting on Q3 were included. Q1: Two studies found that clindamycin and cefpodoxime, respectively, were effective in preventing future APT episodes and in eradicating group A streptococci from the tonsils of RAPT patients. One study found that long-term azithromycin had no effect on the number of APT episodes. Q2: Two studies reported superior clinical and microbiological effects of clindamycin and amoxicillin with clavulanate, respectively, compared to penicillin. The four studies showing superior effects of clindamycin and amoxicillin with clavulanate were assessed to have high risk of bias. Hence, the level of evidence was moderate. There is considerable evidence to suggest that clindamycin and amoxicillin with clavulanate are superior to penicillin with preferable effects on the microbiological flora and the number of future attacks of APT in patients with RAPT. Antibiotic treatment is an option in patients with RAPT, who has contraindications for tonsillectomy.

Abstract
OBJECTIVE Management of tracheal stenosis remains controversial. Endoscopic interventions commonly provide immediate relief of symptoms, but are associated with high recurrence rates. In contrast, high success rates have been reported in patients undergoing tracheal resection. However, well-defined indications and contraindications for tracheal resection are lacking and previous studies commonly ignore patient-related outcomes (e.g. dyspnoea). We aimed to evaluate the outcome of tracheal resection at our institution and identify risk factors for complications. METHODS All adult patients undergoing tracheal resection at Aarhus University Hospital between January 2009 and September 2016 were included RESULTS: Twenty-seven patients were included. The most frequent aetiologies for tracheal stenosis were previous tracheostomy (n=8), prolonged intubation (n=3), a combination of the two (n=5), and intraluminal tumour (n=7). Sixteen patients underwent high tracheal resection, seven patients low tracheal resection, and four patients partial cricotracheal resection. Surgical success (no dyspnoea and no need for additional intervention) was achieved in 74% of patients. Four of six patients undergoing resection because of malignant disease were recurrence-free during the follow-up period. Fifteen (56%) patients suffered complications (transient or permanent). Four (15%) patients had recurrent stenosis and underwent reintervention. Other permanent complications included idiopathic hoarseness (15%), unilateral recurrent nerve palsy (11%), and dysphagia (7%). Previous treatment (endoscopic and open surgery) (OR=5.5, p=0.06) and chronic diseases (OR=8.3, p=0.02) were associated with increased risk for complications. CONCLUSIONS Tracheal resection was efficient treatment for the alleviation of dyspnoea in adults with tracheal stenosis. However, complications were frequent and careful preoperative patient selection and information are crucial.

Abstract
INTRODUCTION The significant pathogens in acute epiglottitis (AE) are poorly defined in the post Haemophilus influenza type b-vaccine era. Furthermore, there is a lack of clinical evaluations of antibiotic regimens in patients with AE. We aimed to evaluate the effectiveness of empiric intravenous ampicillin in the treatment of patients with AE. MATERIALS & METHODS All patients admitted with AE to the Ear-Nose-Throat Department, Aarhus University Hospital, Denmark, from 2001 to 2015 were included. RESULTS In total, 103 (51 males) patients were included in the study. The median duration of hospitalization was four days. There was no statistical significant difference between patients initially treated with intravenous ampicillin (n = 83) or other antibiotics (n = 20) (p = .26). The antibiotic regimen was altered during admission in 11% of patients, without significant difference between antibiotic groups (ampicillin 10% vs non-ampicillin 15%, p = .44). Complications potentially related to insufficient antibiotic treatment were observed in four (5%) patients initially treated with ampicillin, but in none of the patients initially treated with antibiotics other than ampicillin (p = 1.00). Throat swab cultures and blood cultures frequently yielded negative results. CONCLUSIONS Intravenous ampicillin is efficient as empiric antibiotic therapy for AE patients, leading to a quick recovery and low complication rates.

Abstract
BACKGROUND We hypothesized that tonsillectomy modifies the risk of PD. OBJECTIVES To test the hypothesis in a nationwide population-based cohort study. METHODS We used Danish medical registries to construct a cohort of all patients in Denmark with an operation code of tonsillectomy 1980-2010 (n = 195,169) and a matched age and sex general population comparison cohort (n = 975,845). Patients were followed until PD diagnosis, death, censoring, or end of follow-up 30 November 2013. Using Cox regression, we computed hazard ratios for PD and corresponding 95% confidence intervals, adjusting for age and sex by study design, and potential confounders. RESULTS We identified 100 and 568 patients diagnosed with PD among the tonsillectomy and general population comparison cohort, respectively, finding similar risks of PD (adjusted hazard ratio = 0.95 [95% confidence interval: 0.76-1.19]; for > 20 years' follow-up (adjusted hazard ratio = 0.96 [95% confidence interval: 0.64-1.41]). CONCLUSION Tonsillectomy is not associated with risk of PD, especially early-onset PD. © 2017 International Parkinson and Movement Disorder Society.

Abstract
PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated. Complications are relatively rare. They include parapharyngeal abscess (PPA), upper airway obstruction, Lemierre´s syndrome, necrotizing fasciitis, mediastinitis, erosion of the internal carotid artery, brain abscess, and streptococcal toxic shock syndrome. The treatment consists of abscess drainage and antimicrobial therapy. There are three accepted methods of surgical intervension: needle aspiration, incision and drainage (ID), and acute tonsillectomy (á chaud). Internationally, there is a strong trend towards less invasive surgical approach to PTA treatment with avoidance of acute tonsillectomy, needle aspiration instead of ID, and in some cases even antibiotic treatment without surgical drainage. The preferred antibiotic regimen varies greatly between countries and centers. Group A streptococcus (GAS) is the only established pathogen in PTA. However, GAS is only recovered from approximately 20% of PTA patients. The pathogens in the remaining 80% are unknown. Culturing of PTA pus aspirates often yields a polymicrobial mixture of aerobes and anaerobes. As the tonsils of healthy individuals are already heavily and diversely colonized, the identification of significant pathogens is challenging. In addition, when studying PTA microbiology, one must consider diagnostic precision, collection, handling, and transportation of appropriate specimens, choice of methodology for detection and quantification of microorganisms, current or recent antibiotic treatment of patients, potential shift in significant pathogens during the course of infection, and factors associated with increased risk of PTA development. The trend towards de-escalated surgical intervention and increasing reliance on antibiotic treatment, require studies defining the significant pathogens in PTA in order to determine optimal antibiotic regimens. Complications secondary to PTA may be avoided or better controlled with improved knowledge concerning the significant pathogens in PTA. Furthermore, identification of pathogens other than GAS, may lead the way for earlier bacterial diagnosis and timely intervention before abscess formation in sore throat patients. The identification and quantification of risk factors for PTA development constitutes another approach to reduce the incidence of PTA. As clinicians, we noticed that FN was recovered from PTA patients with increasing frequency and that patients infected with Fusobacterium necrophorum (FN) seemed to be more severely affected than patients infected with other bacteria. Furthermore, we occationally observed concomitant PPA in addition to a PTA, which made us hypothesize that PPA and PTA is often closely related and may share significant pathogens. Hence, our aims were: 1. To explore the microbiology of PTA with a special attention to Fusobacterium necrophorum (FN). 2. To elucidate whether smoking, age, gender, and seasons are risk factors for the development of PTA. 3. To characterize patients with PPA, explore the relationship between PPA and PTA, identify the pathogens associated with PPA, and review our management of PPA. In a retrospective study on all 847 PTA patients admitted to the ENT department at Aarhus University Hospital (AUH) from 2001 to 2006, we found that FN was the most prevalent (23%) bacterial strain in pus specimens. FN-positive patients displayed significantly higher infection markers (CRP and neutrophil counts) than patients infected with other bacteria (P = 0.01 and P < 0.001, respectively). In a subsequent prospective and comparative study on 36 PTA patients and 80 patients undergoing elective tonsillectomy (controls), we recovered FN from 58% of PTA aspirates. Furthermore, FN was detected significantly more frequently in the tonsillar cores of PTA patients (56%) compared to the tonsillar cores of the controls (24%) (P = 0.001). We also analysed sera taken acutely and at least two weeks after surgery for the presence of anti-FN antibodies. We found increasing levels (at least two-fold) of anti-FN antibodies in eight of 11 FN-positive (in the tonsillar cultures) PTA patients, which was significantly more frequent compared to none of four FN-negative PTA patients and nine of 47 electively tonsillectomized controls (P = 0.026 and P < 0.001, respectively). Blood cultures obtained during acute tonsillectomy mirrored the bacterial findings in the tonsillar specimens with 22% of patients having bacteremia with FN. However, bacteremia during elective tonsillectomy was at least as prevalent as bacteremia during quinsy tonsillectomy, which challenges the distinction made by the European Society of Cardiology between quinsy and elective tonsillectomy, namely that antibiotic prophylaxis is only recommended to patients undergoing procedures to treat an established infection (i.e. PTA). Using PCR analysis for the presence of herpes simplex 1 and 2, adenovirus, influenza A and B, Epstein-Barr virus (EBV), and respiratory syncytial virus A and B, we explored a possible role of viruses in PTA. However, our results did not indicate that any of these viruses are involved in the development of PTA. Privious studies have documented an association between EBV and PTA in approximately 4% of PTA cases. In addition to the involvement of GAS, the following findings suggest a pathogenic role for FN in PTA: 1. Repeated high isolation rates of FN in PTA pus aspirates. 2. Higher isolation rates in PTA patients compared to electively tonsillectomised controls. 3. Development of anti-FN antibodies in FN-positive patients with PTA. 4. Significantly higher inflammatory markers in FN-positive patients compared to PTA patients infected with other bacteria. We studied the smoking habits among the same 847 PTA patients admitted to the ENT department, AUH from 2001 to 2006. We found that smoking was associated with increased risk of PTA for both genders and across all age groups. The increased risk of PTA among smokers was not related to specific bacteria. Conclusions on causality cannot be drawn from this retrospective study, but the pathophysiology behind the increased risk of PTA in smokers may be related to, previously shown, alterations in the tonsillar, bacterial flora or the local and systemical inflammatory and immunological milieu. Studying all 1,620 patients with PTA in Aarhus County from 2001 to 2006 and using population data for Aarhus County for the same six years, age- and gender-stratified mean annual incidence rates of PTA were calculated. The incidence of PTA was highly related to age and gender. The seasonal variation of PTA was insignificant. However, the microbiology of PTA fluctuated with seasons: GAS-positive PTA cases were significantly more prevalent in the winter and spring compared to the summer, while FN-positive PTA patients exhibited a more even distribution over the year, but with a trend towards higher prevalence in the summer than in the winter. In a series of 63 patients with PPA, we found that 33 (52%) patients had concomitant PTA. This association between PPA and PTA was much higher than previously documented. We therefore suggest that combined tonsillectomy and intrapharyngeal incision in cases where PTA is present or suspected. The results of our routine cultures could not support a frequent role of FN in PPA. Based on our findings suggesting that FN is a frequent pathogen in PTA, we recommend clindamycin instead of a macrolide in penicillin-allergic patients with PTA. Furthermore, cultures made from PTA aspirates should include a selective FN-agar plate in order to identify growth of this bacterium. Recent studies of sore throat patients document an association between recovery of FN and acute tonsillitis. Studying the bacterial flora of both tonsils in study II, we found almost perfect concordance between the bacterial findings of the tonsillar core at the side of the abscess and contralaterally. This finding suggests that FN is not a subsequent overgrowth phenomenon after abscess development, but that FN can act as pathogen in severe acute tonsillitis. Future studies of patients with FN-positive acute tonsillitis focusing on the optimal methods (clinical characteristics, culture, polymerase chain reaction, or other) for diagnosis and whether antibiotics (and which) can reduce symptoms and avoid complications are warranted. Until further studies are undertaken, we recommend clinicians to have increased focus on acute tonsillitis patients aged 15-24 years with regards to symptoms and findings suggestive of incipient peritonsillar involvement. We have conducted a number of studies with novel findings: 1. FN is a significant and prevalent pathogen in PTA. 2. Bacteremia during abscess tonsillectomy is no more prevalent than during elective tonsillectomy. 3. The development of anti-FN antibodies in FN-positive PTA patients. We have used novel approaches as principles to suggest pathogenic significance of candidate microorganisms: 1. Comparative microbiology between PTA patients and "normal tonsils". 2. Measurements indicating larger inflammatory response compared to clinically equivalent infection.

Abstract
OBJECTIVE To review the literature concerning the 2 primary hypotheses put forth to explain the pathogenesis of peritonsillar abscess: "the acute tonsillitis hypothesis" (peritonsillar abscess is a complication of acute tonsillitis) and "the Weber gland hypothesis" (peritonsillar abscess is an infection of Weber's glands). DATA SOURCES PubMed, EMBASE. REVIEW METHODS Data supporting or negating one hypothesis or the other were elicited from the literature. CONCLUSIONS Several findings support the acute tonsillitis hypothesis. First, the 2 main pathogens in peritonsillar abscess have been recovered from pus aspirates and bilateral tonsillar tissues with high concordance rates, suggesting that both tonsils are infected in patients with peritonsillar abscess. Second, studies report signs of acute tonsillitis in the days prior to and at the time of peritonsillar abscess. Third, antibiotic treatment reduces the risk of abscess development in patients with acute tonsillitis. However, some findings suggest involvement of the Weber's glands in peritonsillar abscess pathogenesis. First, high amylase levels have been found in peritonsillar pus. Second, the majority of peritonsillar abscesses are located at the superior tonsillar pole in proximity of the Weber's glands. We propose a unified hypothesis whereby bacteria initially infect the tonsillar mucosa and spread via the salivary duct system to the peritonsillar space, where an abscess is formed. IMPLICATIONS FOR PRACTICE Our findings support the rationale for antibiotic treatment of patients with severe acute tonsillitis to reduce the risk of abscess development. Improved understanding of peritonsillar abscess pathogenesis is important for the development of efficient prevention strategies.

Abstract
INTRODUCTION More than 1,100 thyroid operations are performed annually in Denmark. The major concern regarding outpatient thyroid surgery (OTS) is post-thyroidectomy bleeding (PTB), which may cause compression of the trachea and compromise respiration. We aimed to explore the incidence of PTB and the exact timespan from surgery to PTB, and to identify risk factors for PTB in order to discuss whether OTS can be considered safe. METHODS Data from the Ear-Nose-Throat Department, Aarhus University Hospital, covering the period from January 2001 to August 2013 were collected from the THYRKIR database, and the medical records of patients with PTB were reviewed. RESULTS A total of 42 (2.8%) patients were re-operated due to PTB. Multivariate logistic regression analysis identified male gender (odds ratio (OR) = 1.85) and thyrotoxicosis (OR = 2.68) as risk factors for PTB. PTB occurred within 6 h of surgery in 63% of cases, between 6 and 24 h in 25% of cases, and more than 24 h after surgery in 13% of cases. One patient required urgent reoperation due to acute respiratory insufficiency. CONCLUSION Although a rare event, PTB is potentially life-threatening, and unselected routine OTS cannot be considered safe. Until more studies have been conducted on the selection of patients suitable for OTS, we recommend, as a minimum, that patients are observed for at least 6 h after surgery and subsequently stay at a nearby hospital hotel until discharge 16 to 24 h postoperatively. FUNDING not relevant. TRIAL REGISTRATION The study was approved by the Danish Data Protection Agency (1-16-02-170-14).

Abstract
A 68-year-old man was admitted to hospital in an acute confusional state with a 2-week history of fever, influenza-like illness and sore throat. He quickly developed coagulation disturbances, hypotension and renal function impairment. Despite broad-spectrum antibiotic therapy, he deteriorated. Group A streptococcus (GAS) was recovered from blood cultures, which gave the diagnosis streptococcal toxic shock syndrome (STSS). A computed tomography scan showed a right-sided peritonsillar abscess (PTA). Acute tonsillectomy was carried out and the patient recovered. STSS complicating PTA has not previously been described in the literature, but GAS is a common pathogen in PTA. Clinicians should be aware that STSS can develop secondary to tonsillar infections and that abscess development should be suspected in STSS patients who do not respond to antibiotic treatment.

Abstract
The incidence of tonsillar carcinomas associated with Human Papillomavirus (HPV) infection has increased dramatically over the last three decades. In fact, currently in Scandinavia, HPV-associated cases account for over 80 % of tonsillar carcinoma cases. Yet, the epidemiology and natural history of tonsillar HPV infections remains poorly characterized. Our aim was to characterize such infections in the Danish population in tumor-free tonsillar tissue. Unlike previous studies, we considered both palatine tonsils. We examined both tonsils from 80 patients with peritonsillar abscess (n = 25) or chronic tonsillar disease (n = 55). HPV was detected by nested PCR with PGMY 09/11 and GP5+/GP6+L1 consensus primers, and typed by sequencing. Samples were also analyzed using a higher-throughput method, the CLART HPV 2 Clinical Array Assay. The overall prevalence of HPV tonsillar infection was 1.25 % (1/80, 95 % CI 0.03-6.77 %) by nested PCR, and 0 % by CLART HPV2 Clinical Array. The HPV-positive patient was a 16-year-old female with recurrent tonsillitis and tonsillar hypertrophy. The type detected was HPV6. HPV was not detected in the contralateral tonsil of this patient. Compared to cervical HPV infections in Denmark, tonsillar HPV infections are 10- to 15-fold less frequent. In the HPV-positive patient in this study, HPV was detected in only one of the tonsils. This raises the possibility that prior studies may underestimate the prevalence of HPV infections, as they do not consider both palatine tonsils.

Abstract
BACKGROUND The Centor criteria and the streptococcal rapid antigen detection test (RADT) are commonly used to differentiate sore throat patients with group A streptococci (GAS) from patients with other pathogens. We aimed to investigate if procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC), and absolute neutrophil count (ANC) could increase the diagnostic accuracy when added to the Centor score and RADT, or be used instead of the RADT, in the differential diagnosis. METHODS A 6-month prospective study was carried out in a Danish general practice with 8 physicians. One hundred acute tonsillitis patients aged 15 to 40 y were included. RESULTS The prevalence of GAS was 26%. The sensitivity (90%) and specificity (97%) of the RADT were high. Mean values of CRP, WBC, and ANC were significantly higher in patients with GAS compared to non-GAS patients (p < 0.001). However, the sensitivities (66-90%) and specificities (45-75%) were low. No difference in PCT levels was found (p = 0.334). CRP was the most reliable infection marker (sensitivity 90% and specificity 45%) for GAS aetiology. CONCLUSIONS The sensitivity, specificity, and area under the curve of the RADT were higher than those of the 4 measured infection markers in the differentiation between GAS and non-GAS acute tonsillitis patients. The infection markers did not increase the diagnostic accuracy when added to the Centor score and RADT. When RADT is not available, measurement of CRP or ANC may increase the diagnostic accuracy in the detection of GAS-positive patients.

Abstract
To explore the correlations among the incidence, microbiology, season, gender, and age in patients with peritonsillar abscess (PTA) in order to identify risk factors for PTA development. All patients with PTA treated at private ENT practices in Aarhus County and in the Ear-Nose-Throat Departments at Aarhus University Hospital and Randers Hospital from January 2001 to December 2006 were included in the study. Age- and gender-stratified population data for Aarhus County for the same 6 years were obtained. The incidence rate of PTA increased from childhood to peak in teenage life and declined afterward gradually until old age. Girls predominated over boys until the age of 14 years. Subsequently, men were more frequently affected than women. Fusobacterium necrophorum (FN) was significantly more prevalent than group A Streptococcus (GAS) among patients aged 15-24 years (P < 0.001). In contrast, GAS was significantly more frequently recovered among children aged 0-9 years and adults aged 30-39 years compared with FN (P < 0.001 and P = 0.017 respectively). The seasonal variation of PTA was statistically insignificant (P = 0.437). However, GAS was significantly more frequently recovered in the winter and spring than in the summer (P = 0.002 and P = 0.036 respectively). There was a trend toward a higher incidence of FN infection during the summer than the winter (P = 0.165). Although the collected PTA incidence was stable throughout the year, the microbiology fluctuated with seasons. Patients aged 15-24 years are at an increased risk of PTA due to FN, which may have clinical implications for the diagnostic work-up and treatment of patients with acute tonsillitis.

Abstract
To characterize patients with parapharyngeal abscess admitted to a Danish tertiary care centre and evaluate our management. This is a retrospective chart review. All records of patients with parapharyngeal abscess admitted to the Ear-Nose-Throat Department at Aarhus University Hospital, Denmark, from January 2001 through December 2011 were reviewed. In total, 63 patients (41 males), aged 4-89 years (median, 45 years) were included in the study. The mean annual incidence of parapharyngeal abscess was 0.9 cases/100,000 population. Thirty-three (52%) patients had concomitant peritonsillar abscess. In two patients the parapharyngeal abscess was accompanied by necrotizing fasciitis. The most frequent surgical approach used was intrapharyngeal incision in combination with tonsillectomy. The most commonly used antibiotic regimen was benzylpenicillin plus metronidazole. Seven (13%) patients returned to the operating theatre due to post-tonsillectomy haemorrhage or insufficient abscess drainage. Tonsillectomy and internal incision of the abscess in combination with a narrow-spectrum intravenous penicillin and metronidazole is a safe and efficient approach for managing parapharyngeal abscesses. This approach, however, carries a relatively high complication rate, requiring close surveillance in the early post-operative period. This is especially true for parapharyngeal abscess patients without peritonsillar abscess. In our series, these patients were more ill, more likely to experience complications, require intensive care, intubation, and tracheotomy, than parapharyngeal abscess patients with concurrent peritonsillar abscess. The frequent co-existence of parapharyngeal abscess and peritonsillar abscess favours careful consideration of addition of tonsillectomy to intrapharyngeal incision.

Abstract
INTRODUCTION Infection markers are appreciated supplements in the clinical diagnosis of ear, nose and throat (ENT) infections. We aimed to examine the differential diagnostic usefulness of C-reactive protein (CRP), white blood cell count (WBC) and absolute neutrophil count (ANC) according to severity of middle ear and tonsillar infections. MATERIAL AND METHODS This was a retrospective study including all patients admitted to the ENT Department, Aarhus University Hospital, from January 2001 to December 2008 and diagnosed with acute otitis media, mastoidismus, acute mastoiditis, acute tonsillitis, peritonsillar abscess, parapharyngeal abscess and necrotizing fasciitis. RESULTS A total of 1,773 patients were included. Between the tonsil subgroups, significant differences were found in CRP (p < 0.001), WBC (p < 0.001) and ANC (p < 0.001) levels. However, sensitivities and specificities related to differential diagnostics were low. In the middle ear group, no differences in CRP (p = 0.84), WBC (p = 0.46), and ANC (p = 0.72) levels were found. The number of CRP levels above the reference value was significantly higher than the corresponding number of WBC and ANC levels. A trend (non-significant) was found towards lower parameter levels in acute tonsillitis and peritonsillar abscess patients who grew Staphylococcus aureus compared with patients infected with other bacteria. CONCLUSION CRP and ANC levels were related to severity of tonsillar-derived infections, but no such relation was found in infections with middle ear origin. None of the infection markers studied were useful for differential diagnostics. FUNDING not relevant. TRIAL REGISTRATION not relevant.

Abstract
INTRODUCTION Foreign body (FB) aspiration is a common cause of respiratory emergency in early childhood and is associated with a high rate of airway distress. FB aspiration peaks at the age of 1-2 years. Factors placing children at higher risk include incomplete dentition, immature swallowing coordination and the tendency to be easily distracted while eating. Symptoms may vary from an un-affected child to impending airway failure. Mucosal cough receptors often accommodate and the child may be asymptomatic when evaluated. MATERIAL AND METHODS Files of children (0-15 years) admitted with suspected FB aspiration were reviewed. Patients were included if the FB was confirmed by bronchoscopy. RESULTS Among 136 children undergoing bronchoscopy, a FB was confirmed in 59 patients. The median age was one year. All children had a history of aspiration and in 48% a persistent cough was present at the initial examination. Eleven children (19%) had a normal physical examination at admission. Nuts were identified in 34% and carrots in 20%. Of the FBs removed, 86% were organic and 14% were inorganic. Organic FBs were more common in patients younger than three years (p < 0.001). CONCLUSION Parental suspicion of FB aspiration indicates acute bronchoscopy in children, even in case of no abnormal findings. The completion of the bronchoscopy within 24 hours facilitates the examination and reduces the risk of complications. We recommend increased awareness of the hazards associated with small crunchy organic food items, especially nuts and carrots, given to children under three years of age. FUNDING not relevant.

Abstract
AIMS Bacteremia during elective tonsillectomy is well recognized, whereas bacteremia during quinsy tonsillectomy has never been studied. The aim of the present study was to explore the incidence of bacteremia during elective and quinsy tonsillectomy in order to evaluate the antibiotic prophylaxis recommendations to patients at high risk of infective endocarditis who are undergoing tonsillectomy. METHODS A prospective study was conducted on 80 patients undergoing elective tonsillectomy and 36 patients undergoing acute tonsillectomy due to peritonsillar abscess. Blood cultures, tonsillar swabs, core tissue, and pus aspirates were analyzed by standard microbiological techniques. RESULTS Bacteremia was detected in 73% of patients during elective tonsillectomy compared to 56% during quinsy tonsillectomy (P = .089, Fishers exact test). Significantly more blood culture bottles were positive for each isolate obtained from elective tonsillectomy cases compared to quinsy tonsillectomy cases (P < .001, Spearman rank correlation). In all, 59% and 42% of electively and acutely tonsillectomized patients, respectively, had bacteremia with microorganisms that are predominant in bacterial endocarditis. Ninety-three percent of the isolated strains were sensitive to amoxicillin, and all were sensitive to amoxicillin with clavulanic acid. DISCUSSION Our results challenge the distinction made by the European Society of Cardiology between elective and quinsy tonsillectomy, with regard to antibiotic prophylaxis recommendation only to patients undergoing procedures to treat an established infection. To provide full empiric coverage, including coverage for Staphylococcus aureus, we advocate the use of amoxicillin with clavulanic acid in patients at high risk of infective endocarditis.

Abstract
INTRODUCTION Recent studies implicate the presence of Fusobacterium necrophorum (FN) in recurrent tonsillitis (RT), acute tonsillitis and peritonsillar abscess. The objective of the present study was to determine whether FN plays a role in RT by comparing bacteriologic results from patients suffering from RT, tonsillar hypertrophy and halitosis or persistent sore throat syndrome (PSTS). We analyzed both tonsils to determine the degree of concordance. MATERIAL AND METHODS A prospective study was conducted in 80 patients aged 8-30 years who were undergoing elective tonsillectomy. The patients were divided into four groups according to indication for surgery. Aerobic and anaerobic cultures from the tonsillar surface and core were analyzed. RESULTS FN was detected less frequently in the tonsillar cores of RT patients (22%) than in those of patients without RT (30%) (p=0.44). FN detection frequencies ranged between 20% and 35% across the four groups. Betahaemolytic streptococci groups A/C/G (BHS) were detected significantly (p=0.007) more often in the RT group than in the halitosis/PSTS group. CONCLUSION A possible role of FN in RT was not substantiated. Our results indicate that FN is likely to be part of the normal flora. The tonsillar surface and core flora carry considerable interpersonal diversity, but is very similar bilaterally in each individual. Other factors seem to play a major role in the development of the represented tonsillar diseases. FUNDING Not relevant. TRIAL REGISTRATION The study was approved by The Research Ethics Committee of Aarhus County (no. 20050034).

Abstract
INTRODUCTION The aim of this study was to quantify the incidence and evaluate the risk factors of post-tonsillectomy hemorrhage (PTH). MATERIALS AND METHODS A retrospective study was performed of all patients with PTH at the three hospital departments in Aarhus County, Denmark (650,000 inhabitants), and a random sample of one-third of all tonsillectomised patients at Aarhus University Hospital (AS) in the period 1 December 2002 to 30 November 2003, during which period 918 patients were tonsillectomised. RESULTS Post-operative haemorrhage occured in a total of 48 patients (5.2%). Twenty-six patients (2.8%) needed re-operation: 12 (3.4%) at AS, 7 (3.7%) at Randers Centralsygehus (RCS) and 7 (1.8%) at Silkeborg Centralsygehus (SCS). The following factors correlated significantly with PTH: high age (p = 0.0093), greater perioperative blood loss (p = 0.026) and high perioperative blood pressure (p = 0.0007). In addition, we found a three times higher but insignificant (p = 0.26) risk during abscess tonsillectomy as compared to cold tonsillectomy. CONCLUSION The three ENT departments of Aarhus County fulfil international standards, but the operation has a high complication rate, which emphasizes the importance of solid indications for operation. In light of the increased risk of PTH with higher age, the instructions at AS have been altered so that all patients over 20 years of age with peritonsillar abscess who can cooperate are treated with aspiration and incision.
