Insights
Recurrent parotitis in children may indicate primary Sjögren syndrome (SS), an autoimmune condition. Early diagnosis is crucial for effective pediatric Sjögren syndrome management and treatment.
Area of Science:
- Pediatric Rheumatology
- Ophthalmology
- Immunology
Background:
- Parotitis is common in children, often viral or bacterial.
- Recurrent parotitis necessitates a broader differential diagnosis.
- Primary pediatric Sjögren syndrome (SS) is a rare autoimmune cause.
Observation:
- Four pediatric cases of isolated recurrent bilateral parotitis are presented.
- Patients aged 9-17 years at presentation.
- Ocular findings were present in 3/4 patients despite no subjective complaints.
Findings:
- Laboratory results showed positive antinuclear antibody, SS A, SS B antibodies, rheumatoid factor, and hypergammaglobulinemia.
- Pediatric SS often presents with isolated parotitis, differing from adult presentation.
- Ophthalmologic examination revealed abnormalities in most patients.
Implications:
- Sjögren syndrome should be considered in children with recurrent parotitis.
- Timely diagnosis of pediatric SS enables appropriate management.
- Understanding pediatric SS presentation is vital for pediatricians and specialists.
Abstract:
Parotitis is a common condition seen in the pediatric population, usually as an isolated occurrence associated with viral or bacterial infection. The differential diagnosis expands when recurrent parotitis is encountered. One etiology is primary pediatric Sjögren syndrome (SS), an autoimmune condition typically associated with dryness of the eyes and mouth in adults. Pediatric patients often present with isolated recurrent bilateral parotitis, however, and we describe 4 such cases in children aged 9 to 17 years at presentation. Despite lack of ocular complaints, 3 of these patients had ocular findings on ophthalmologic exam. Our patients also exhibited classic laboratory abnormalities, including positive antinuclear antibody, SS A, and SS B antibodies; presence of rheumatoid factor; and hypergammaglobulinemia. Consideration of SS in the child with recurrent parotitis is important for timely and appropriate referral and treatment. We review the differential diagnosis of parotitis in children as well as the salient features of pediatric SS.

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:
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
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,...
