Conclusion:
RPA and NF was diagnosed with a sensitivity/specificity of 100%/94% in patients with acute tonsillitis and without suspicion for disease complication after ENT examination, but an age >35 years and serum CRP >15.5mg/dl.
Background:
Acute tonsillitis represents a frequent disease in the otorhinolaryngology. Some patients exhibit disease aggravations resulting in (descending) peritonsillar abscess (PTA, dPTA), para-/retropharyngeal abscess (PPA, RPA), or necrotising fasciitis (NF). The study analyses the underlying predisposing factors.
Methods:
The retrospective cohort study includes a total of 1636 patients comprising 852 outpatients with acute bacterial tonsillitis, 279 in-patients with acute bacterial tonsillitis, 452 patients with PTA, 31 patients with dPTA/PPA, 12 patients with RPA, and 10 patients with NF. Patients were analysed for disease-related data.
Results:
While leucocytes do not distinguish the sub-groups, C-reactive protein demonstrated a significant increase resulting in the highest level for RPA and NF (p < 0.0001). PTA and RPA are usually caused by streptococcus, dPTA/PPA by anaerobic bacterias, and NF mixed infections (p < 0.0001). Patients with PTA were younger than dPTA/PPA (p = 0.002) or RPA/NF (p < 0.0001). Subsequently, the rate of internistic comorbidities was significantly increased in RPA/NF (p < 0.0001). ROC-analysis identified cut-offs for age <36 years and CRP <15.5mg/dl to distinguish acute bacterial tonsillitis from RPA.

Etiology
Three primary contributing factors have been identified.
01:23Chronic 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,...

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.

Acute pharyngitis can be categorized based on its underlying cause:

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
