Insights
Patients with Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis (PFAPA) syndrome do not face an increased risk of immediate postoperative fever after tonsillectomy. This study found a low incidence of fever, suggesting current management protocols may be overly cautious.
Area of Science:
- Pediatric Otolaryngology
- Pediatric Rheumatology
- Infectious Diseases
Background:
- Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis (PFAPA) syndrome is the most common periodic fever syndrome in children.
- Tonsillectomy is a potential treatment for PFAPA syndrome.
- A common clinical concern is the potential for increased postoperative fever in PFAPA patients, complicating diagnosis and management.
Purpose of the Study:
- To evaluate the incidence of immediate postoperative fever in children with PFAPA syndrome undergoing tonsillectomy.
- To determine if PFAPA patients have a higher risk of postoperative fever compared to the general pediatric population undergoing tonsillectomy.
Main Methods:
- Retrospective chart review of PFAPA patients who underwent tonsillectomy at a tertiary children's hospital (2013-2022).
- Query of the Pediatric Health Information System (PHIS) database for pediatric tonsillectomies and PFAPA diagnoses during the same period.
- Analysis of immediate postoperative fever rates in PFAPA patients.
Main Results:
- Only 1.6% of PFAPA patients (1 out of 61) experienced immediate postoperative fever.
- The incidence of fever episodes significantly decreased post-tonsillectomy in PFAPA patients (100% pre-op vs. 9.75% post-op).
- Analysis of a large national database (PHIS) showed 0.25% of pediatric tonsillectomies were associated with PFAPA, with no reported immediate postoperative fevers in this subgroup.
Conclusions:
- The study suggests that PFAPA syndrome is not associated with an increased risk of immediate postoperative fever following tonsillectomy.
- The findings challenge the notion that PFAPA patients require specialized care at main centers solely due to fever risk post-tonsillectomy.
- Current institutional practices regarding the management of PFAPA patients undergoing tonsillectomy may warrant re-evaluation based on these results.
Objective:
Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is the most common periodic fever syndrome in children. Tonsillectomy is considered a potential treatment option. A common concept is that patients with PFAPA are more likely to have postoperative fever, which might be hard to distinguish from other etiologies such as malignant hyperthermia or drug adverse effects. For this reason, many institutions require these patients to be cared for at their main center and not at satellite centers. Our objective was to evaluate the rate of immediate postoperative fever in PFAPA patients undergoing tonsillectomy.
Material And Methods:
Following IRB approval (STUDY20060029), a retrospective chart review of all PFAPA patients who underwent tonsillectomy at a tertiary children's hospital between January 1st, 2013, and September 30th, 2022. The PHIS database was queried from January 1st, 2013, to June 30th, 2022, for pediatric tonsillectomy and PFAPA.
Results:
Sixty-one patients underwent tonsillectomy for PFAPA during the study period at our institution. Only one (1.6 %) had immediate postoperative fever. Fever episode resolution was seen in 90.25 % of patients, 41/41 (100 %) of the patients reported fever episodes pre-op, compared with 4/41 (9.75 %) post-op (McNemar's Chi-squared test, Chi2 = 37.0, p < 0.001). 481,118 pediatric tonsillectomies were recorded in the PHIS database during this period, 1197 (0.25 %) were also diagnosed with PFAPA. None of the PFAPA patients had an immediate post-operative fever.
Conclusions:
Our results suggest there is no increased risk of immediate postoperative fever in PFAPA patients undergoing tonsillectomy.

Tonsillitis II: Management
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Increased Body Temperature
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....
