Auris Nasus Larynx. 2020 Aug;47(4):559-564. doi: 10.1016/j.anl.2020.06.003. Epub 2020 Jun 15.
Abstract/Text
OBJECTIVE: to detect, analyze and discuss the different ear nose throat (ENT) manifestations those were reported in COVID19 positive patients in the reviewed and published literatures.
METHODS: We performed a search in the PubMed databases, Web of Science, LILACS, MEDLINE, SciELO, and Cochrane Library using the keywords; COVID-19, Novel coronavirus, corona, 2019-nCoV, SARS-CoV-2, ENT, ear, nose, throat, otorhinolaryngology, ORL, pharynx, ORL, smell, larynx, different ENT related symptoms. We reviewed published and peer reviewed studies that reported the ENT manifestations in COVID-19 laboratory-confirmed positive patients.
RESULTS: within the included 1773 COVID-19 laboratory-confirmed positive patients, the most common ENT manifestations of COVID-19 were sore throat (11.3%) and headache (10.7%). While the other reported ENT manifestations were pharyngeal erythema (5.3%), nasal congestion (4.1%), runny nose or rhinorrhea (2.1%), upper respiratory tract infection (URTI) (1.9%), and tonsil enlargement (1.3%).
CONCLUSION: ENT manifestations for COVID-19 are not common as fever and cough. But, a universal questionnaire using well-defined COVID-19 manifestations is needed to make the COVID-19 data precisely defined, complete and homogenous.

The clinical presentation of Fusobacterium-positive and streptococcal-positive pharyngitis in a university health clinic: a cross-sectional study.
Ann Intern Med. 2015 Feb 17;162(4):241-7. doi: 10.7326/M14-1305.
Abstract/Text
BACKGROUND: Pharyngitis guidelines focus solely on group A β-hemolytic streptococcal infection. European data suggest that in patients aged 15 to 30 years, Fusobacterium necrophorum causes at least 10% of cases of pharyngitis; however, few U.S. data exist.
OBJECTIVE: To estimate the prevalence of F. necrophorum; Mycoplasma pneumoniae; and group A and C/G β-hemolytic streptococcal pharyngitis and to determine whether F. necrophorum pharyngitis clinically resembles group A β-hemolytic streptococcal pharyngitis.
DESIGN: Cross-sectional.
SETTING: University student health clinic.
PATIENTS: 312 students aged 15 to 30 years presenting to a student health clinic with an acute sore throat and 180 asymptomatic students.
MEASUREMENTS: Polymerase chain reaction testing from throat swabs to detect 4 species of bacteria and signs and symptoms used to calculate the Centor score.
RESULTS: Fusobacterium necrophorum was detected in 20.5% of patients and 9.4% of asymptomatic students. Group A β-hemolytic streptococcus was detected in 10.3% of patients and 1.1% of asymptomatic students. Group C/G β-hemolytic streptococcus was detected in 9.0% of patients and 3.9% of asymptomatic students. Mycoplasma pneumoniae was detected in 1.9% of patients and 0 asymptomatic students. Infection rates with F. necrophorum, group A streptococcus, and group C/G streptococcus increased with higher Centor scores (P < 0.001).
LIMITATIONS: The study focused on a limited age group and took place at a single institution. Asymptomatic students-rather than seasonal control participants-and a convenience sample were used.
CONCLUSION: Fusobacterium necrophorum-positive pharyngitis occurs more frequently than group A β-hemolytic streptococcal-positive pharyngitis in a student population, and F. necrophorum-positive pharyngitis clinically resembles streptococcal pharyngitis.

A clinical score to reduce unnecessary antibiotic use in patients with sore throat.
CMAJ. 1998 Jan 13;158(1):75-83.
Abstract/Text
OBJECTIVE: To validate a score based on clinical symptoms and signs for the identification of group A Streptococcus (GAS) infection in general practice patients with score throat.
DESIGN: A single throat swab was used as the gold standard for diagnosing GAS infection. Clinical information was recorded by experienced family physicians on standardized encounter forms. Score criteria were identified by means of logistic regression modelling of data from patients enrolled in the first half of the study. The score was then validated among the remaining patients.
SETTING: University-affiliated family medicine centre in Toronto.
PATIENTS: A total of 521 patients aged 3 to 76 years presenting with a new upper respiratory tract infection from December 1995 to February 1997.
OUTCOME MEASURES: Sensitivity, specificity and likelihood ratios for identification of GAS infection with the score approach compared with throat culture. Proportion of patients prescribed antibiotics, throat culture use, and sensitivity and specificity with usual physician care and with score-based recommendations were compared.
RESULTS: A score was developed ranging in value from 0 to 4. The sensitivity of the score for identifying GAS infection was 83.1%, compared with 69.4% for usual physician care (p = 0.06); the specificity values of the 2 approaches were similar. Among patients aged 3 to 14 years, the sensitivity of the score approach was higher than that of usual physician care (96.9% v. 70.6%) (p < 0.05). The proportion of patients receiving initial antibiotic prescriptions would have been reduced 48% by following score-based recommendations compared with observed physician prescribing (p < 0.001), without any increase in throat culture use.
CONCLUSIONS: An age-appropriate sore throat score identified GAS infection in children and adults with sore throat better than usual care by family physicians, with significant reductions in unnecessary prescribing of antibiotics. A randomized trial comparing the 2 approaches is recommended to determine the ability of the score approach to reduce unnecessary prescribing of antibiotics during routine clinical encounters.

A scoring system for management of acute pharyngo-tonsillitis in adults.
Auris Nasus Larynx. 2009 Jun;36(3):314-20. doi: 10.1016/j.anl.2008.07.001. Epub 2008 Sep 5.
Abstract/Text
OBJECTIVES: The aim of this study was to develop and evaluate a scoring system for the management of acute pharyngo-tonsillitis.
METHODS: We conducted a prospective study between May 2004 and June 2005. Patients with acute pharyngo-tonsillitis were evaluated for causative pathogens and were assessed clinical symptoms and pharyngo-tonsillar finding by a clinical scoring system.
RESULTS: A total 214 adult patients were enrolled in this study. Streptococcus pyogenes were identified at 13.6%. Thirty-one viruses were also identified by PCR. They were adenovirus (4.8%), influenza virus (1.0%), RS virus (6.3%), and human metapneumovirus (2.9%). Numbers of total white blood cells and levels of C-reactive protein showed a significant positive correlation with clinical scores (p<0.001) and were also higher in cases with S. pyogenes. The clinical scores rapidly improved after the antimicrobial treatments in moderate cases and severe cases.
CONCLUSION: The current study strongly suggested that the clinical scoring system reflected disease severity well and would be very useful for evaluating clinical course and decision making for the antimicrobial treatment of acute pharyngo-tonisllitis.

Tonsillitis index: an objective tool for quantifying the indications for tonsillectomy for recurrent acute tonsillitis.
Int J Pediatr Otorhinolaryngol. 2005 Nov;69(11):1515-20. doi: 10.1016/j.ijporl.2005.04.007. Epub 2005 Jun 24.
Abstract/Text
This report is a preliminary exploration of the concept of a "Tonsillectomy Index" (TI) as an objective tool for quantifying the indications for tonsillectomy for recurrent acute tonsillitis (AT). The TI is derived by multiplying the number of episodes of AT by the number of years during which the episodes of AT occurred. Our objective in this study was to investigate whether there is a relationship between the natural history of AT, the immunological functions of tonsils and our proposed TI. For the natural history of AT, we medically followed 11 children with a history of AT for 5 years. When TI was equal to or greater than 8 (TI> or =8), the children suffered a significantly greater number of episodes of AT. For the immunological portion of our study, we enrolled 36 children and 46 adults undergoing tonsillectomy for either AT (study group) or tonsillar hypertrophy (control group, CG). We analyzed the co-stimulatory signals, CD80 and CD86 on tonsillar B-lymphocytes. The expression rates of CD80 and CD86 in the AT group with TI> or =8 were significantly decreased compared to those with TI was less than 8 (TI<8), as well as with those in control (tonsillar hypertrophy) group. Our preliminary findings suggest that when the TI> or =8, the tonsils have deteriorated immunologically and spontaneous resolution of recurrent AT is less likely to occur, hence tonsillectomy is appropriate. TI may be a useful tool for surgical decision making.

Efficacy of tonsillectomy for recurrent throat infection in severely affected children. Results of parallel randomized and nonrandomized clinical trials.
N Engl J Med. 1984 Mar 15;310(11):674-83. doi: 10.1056/NEJM198403153101102.
Abstract/Text
We studied the efficacy of tonsillectomy, or tonsillectomy with adenoidectomy, in 187 children severely affected with recurrent throat infection. Ninety-one of the children were assigned randomly to either surgical or nonsurgical treatment groups, and 96 were assigned according to parental preference. In both the randomized and nonrandomized trials, the effects of tonsillectomy and of tonsillectomy with adenoidectomy were similar. By various measures, the incidence of throat infection during the first two years of follow-up was significantly lower (P less than or equal to 0.05) in the surgical groups than in the corresponding nonsurgical groups. Third-year differences, although in most cases not significant, also consistently favored the surgical groups. On the other hand, in each follow-up year many subjects in the nonsurgical groups had fewer than three episodes of infection, and most episodes among subjects in the nonsurgical groups were mild. Of the 95 subjects treated with surgery, 13 (14 per cent) had surgery-related complications, all of which were readily managed or self-limited. These results warrant the election of tonsillectomy for children meeting the trials' stringent eligibility criteria, but also provide support for nonsurgical management. Treatment for such children must therefore be individualized.

Clinical practice guideline: tonsillitis II. Surgical management.
Eur Arch Otorhinolaryngol. 2016 Apr;273(4):989-1009. doi: 10.1007/s00405-016-3904-x. Epub 2016 Feb 16.
Abstract/Text
In 2013, a total of 84,332 patients had undergone extracapsular tonsillectomies (TE) and 11,493 a tonsillotomy (TT) procedure in Germany. While the latter is increasingly performed, the number of the former is continually decreasing. However, a constant number of approximately 12,000 surgical procedures in terms of abscess-tonsillectomies or incision and drainage are annually performed in Germany to treat patients with a peritonsillar abscess. The purpose of this part of the clinical guideline is to provide clinicians in any setting with a clinically focused multi-disciplinary guidance through the surgical treatment options to reduce inappropriate variation in clinical care, improve clinical outcome and reduce harm. Surgical treatment options encompass intracapsular as well as extracapsular tonsil surgery and are related to three distinct entities: recurrent episodes of (1) acute tonsillitis, (2) peritonsillar abscess and (3) infectious mononucleosis. Conservative management of these entities is subject of part I of this guideline. (1) The quality of evidence for TE to resolve recurrent episodes of tonsillitis is moderate for children and low for adults. Conclusions concerning the efficacy of TE on the number of sore throat episodes per year are limited to 12 postoperative months in children and 5-6 months in adults. The impact of TE on the number of sore throat episodes per year in children is modest. Due to the heterogeneity of data, no firm conclusions on the effectiveness of TE in adults can be drawn. There is still an urgent need for further research to reliably estimate the value of TE compared to non-surgical therapy of tonsillitis/tonsillo-pharyngitis. The impact of TE on quality of life is considered as being positive, but further research is mandatory to establish appropriate inventories and standardized evaluation procedures, especially in children. In contrast to TE, TT or comparable procedures are characterized by a substantially lower postoperative morbidity in terms of pain and bleeding. Although tonsillar tissue remains along the capsule, the outcome appears not to differ from TE, at least in the pediatric population and young adults. Age and a history of tonsillitis are not a contraindication, abscess formation in the tonsillar remnants is an extremely rare finding. The volume of the tonsils should be graded according to Brodsky and a grade >1 is considered to be eligible for TT. The number of episodes during 12 months prior to presentation is crucial to indicate either TE or TT. While surgery is not indicated in patients with less than three episodes, a wait-and-see policy for 6 months is justified to include the potential of a spontaneous healing before surgery is considered. Six or more episodes appear to justify tonsil surgery. (2) Needle aspiration, incision and drainage, and abscess tonsillectomy are effective methods to treat patients with peritonsillar abscess. Compliance and ability of the patient to cooperate must be taken into account when choosing the surgical method. Simultaneous antibiotic therapy is recommended but still subject of scientific research. Abscess tonsillectomy should be preferred, if complications have occurred or if alternative therapeutic procedures had failed. Simultaneous TE of the contralateral side should only be performed when criteria for elective TE are matched or in cases of bilateral peritonsillar abscess. Needle aspiration or incision and drainage should be preferred if co-morbidities exist or an increased surgical risk or coagulation disorders are present. Recurrences of peritonsillar abscesses after needle aspiration or incision and drainage are rare. Interval TE should not be performed, the approach is not supported by contemporary clinical studies. (3) In patients with infectious mononucleosis TE should not be performed as a routine procedure for symptom control. TE is indicated in cases with clinically significant upper airway obstruction resulting from inflammatory tonsillar hyperplasia. If signs of a concomitant bacterial infection are not present, antibiotics should not be applied. Steroids may be administered for symptom relief.

Abstract/Text
Currently there is no agreement on the treatment of patients who develop a peritonsillar abscess (PTA). This lack of consensus results in highly variable and possibly expensive therapeutic regimens that may not provide optimum quality patient care at reasonable cost. The present study evaluates surgical, medical, diagnostic, and cost factors that affect the management of PTA based on the following: 1. a cohort study of 123 patients with PTA treated using needle aspiration as the initial surgical drainage; 2. a national survey of the PTA management practices of otolaryngologists; and 3. meta-analyses of various components of the treatment regimen for PTA. In the cohort study, patients diagnosed with PTA were treated by both otolaryngologists and emergency medicine specialists with needle aspiration as the primary surgical modality resulting in a 96% acute resolution rate for PTA. In the national survey, questionnaires were sent to 2000 randomly selected members of the American Academy of Otolaryngology-Head and Neck Surgery regarding their management of PTA. The return rate was 73%. Ninety-six percent of the physicians who returned survey forms treated an average of seven PTAs per year using either needle aspiration, incision and drainage, or abscess tonsillectomy to drain the abscess initially. The incidence of PTA in the United States and Puerto Rico among patients 5 to 59 years of age treated by survey practitioners is 30.1 per 100,000 person years, accounting for approximately 45,000 cases per year. Four meta-analyses were completed to quantify the success rate of needle aspiration in the treatment of PTA (94%), the recurrence rate of PTA (10% to 15%), the rate at which penicillin-resistant microorganisms are found in patients with PTA (0% to 56%), and the rate of prior oropharyngeal infections associated with PTA (11% to 56%). The recurrence rate for PTA in the United States is 10%, which is significantly different from the recurrence rate of 15% reported from the rest of the world (P < .002). A clinical intervention for PTA is proposed based on the clinical series, the national survey data, and the meta-analyses. These clinical guidelines recommend that needle aspiration be used as the initial surgical drainage procedure for all patients with a PTA other than those who have indications for abscess tonsillectomy. Patients should be treated in an outpatient setting, should receive penicillin if they are not allergic to it, and should receive adequate pain medication. The evidence does not suggest that there is any benefit in examining the abscess contents for microorganisms. Approximately 30% of patients with PTA can be expected to exhibit relative indications for a tonsillectomy.(ABSTRACT TRUNCATED AT 400 WORDS)
