Summary
Shear wave elastography (SWE) reveals significantly higher palatine tonsil stiffness in children with acute tonsillitis compared to healthy children. Increased tonsil volume also correlated with greater elasticity in affected pediatric patients.
Area of Science:
- Pediatric imaging
- Medical diagnostics
- Biophysics
Background:
- Shear wave elastography (SWE) is an established non-invasive method for assessing tissue elasticity.
- Normative data for tonsil stiffness using SWE in healthy children exists.
- Acute tonsillitis is a common pediatric condition affecting palatine tonsils.
Purpose of the Study:
- To investigate and compare palatine tonsil elasticity in children diagnosed with acute tonsillitis versus healthy controls.
- To analyze the relationship between tonsil volume and elasticity in pediatric acute tonsillitis.
Main Methods:
- Prospective study including pediatric patients (4-18 years) with acute tonsillitis and healthy children.
- Exclusion criteria: antibiotic use, chronic tonsillitis, adenoid hypertrophy, chronic diseases, immunodeficiency, autoimmune, or rheumatological diseases.
- Palatine tonsil volume and elasticity were measured using ultrasound and SWE.
Main Results:
- The study included 81 patients with acute tonsillitis and 63 healthy children.
- Significantly higher elasticity (kPa) values were observed in the palatine tonsils of children with acute tonsillitis (SWE-R: 25.39 ± 4.64, SWE-L: 25.01 ± 4.17) compared to healthy controls (SWE-R: 9.71 ± 2.37, SWE-L: 9.39 ± 2.19) (p < 0.001).
- A significant positive correlation was found between tonsil volume and elasticity in the acute tonsillitis group (r: 0.774, p: 0.002).
Conclusions:
- Shear wave elastography demonstrates increased palatine tonsil stiffness in pediatric patients with acute tonsillitis.
- Higher elasticity values correlate with increased tonsil volume in this pediatric population.
- SWE is a valuable tool for assessing palatine tonsil changes in acute tonsillitis.

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
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,...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
