Patients with comorbid rheumatoid arthritis are predisposed to peritonsillar abscess: real-world evidence

Evaluation of Staphylococcus aureus Colonization in Adult Patients Undergoing Tonsillectomy for Recurrent Tonsillitis

Background and objectives: Staphylococcus aureus (S. aureus) is often recovered from the pharynx. However, the role of this pathogen in the etiology of tonsillar inflammation is still unclear and complicated due to frequent carriage of S. aureus. The aim of the study was to evaluate the frequency and the clinical importance of S. aureus colonization and biofilm production ability in patients with recurrent tonsillitis (RT) using patient samples from tonsillar crypts during tonsillectomy, and from the throat, nasal cavity, and armpits after tonsillectomy. Materials and Methods: A case series study was carried out at a tertiary referral center among 16 patients diagnosed with RT who were undergoing tonsillectomy. Samples from tonsillar crypts were obtained during tonsillectomy, and samples from the throat, nasal cavity, and armpit were obtained a year after surgery. An evaluation of S. aureus incidence, biofilm formation, and antibacterial susceptibility was performed. Results: During tonsillectomy, 16 strains of S. aureus were isolated from 16 patients, while 15/16 S. aureus strains were biofilm producers. A year after tonsillectomy, 8 S. aureus strains were isolated from 6 out of 16 patients, while 6/8 S. aureus strains were biofilm producers. After tonsillectomy, 3 patients showed S. aureus in throat culture. Conclusions: In 10/16 cases S. aureus was the causative agent of RT, in 4/16 cases patients had a predisposition to colonization of S. aureus, and in 2/16 cases S. aureus was a part of the patients` oral microbiome. Tonsillectomy results in less frequent isolation of S. aureus strains.

Ubi pus, ibi evacua: a review of 601 peritonsillar abscess adult cases

Background

Peritonsillar abscess (PTA) is the most common deep neck infection, occurring as a consequence of bacterial acute tonsillitis or as a result of infection of the Weber glands, with frequent and life-threatening complications.

Aim

To investigate several factors associated with complications and worse prognosis, such as defining the method of surgical drainage and treatment of a PTA which remains an area of controversy in the literature

Methods

The purpose of this retrospective study is to examine the epidemiological, clinical, and laboratory findings of 601 adult patients and to discuss them along with their treatment plan.

Results

Pharyngalgia was the most common reported symptom, followed by trismus, odynophagia, fever, hot potato voice, malaise, and cervical lymphadenopathy. Sixty-eight patients developed complications. Streptococcus species were the most common pathogens. A statistically significant difference was found in days of hospitalization, WBC and CRP levels, age, and the pre-existing systemic diseases between patients with and without complications. A comparison of patients treated with intravenous and oral antibiotics revealed no statistically significant difference.

Conclusion

Οver 10% of PTA cases may develop complications, the most common of which is extension into deep neck spaces. Comorbid conditions increase the risk of complications. Despite the wide range of treatment strategies, incision and drainage remain the cornerstone of surgical treatment. In patients with no comorbidities, intravenous antibiotics appear to have no advantage over oral antibiotics.
