Insights

Recurrent parotitis of childhood, a relapsing inflammatory disorder of the parotid gland, affects 28% of juvenile parotitis cases. A significant association was found with selective IgA deficiency.

Area of Science:

  • Pediatric immunology
  • Otolaryngology
  • Inflammatory disorders

Background:

  • Recurrent parotitis of childhood is a rare, relapsing inflammatory condition affecting the parotid gland.
  • It can lead to significant morbidity in children.
  • Juvenile parotitis is the idiopathic form of this condition.

Purpose of the Study:

  • To define the prevalence and characteristics of recurrent parotitis of childhood.
  • To investigate potential underlying conditions, specifically selective IgA deficiency, in affected children.

Main Methods:

  • Retrospective chart review of patients diagnosed with inflammatory parotid diseases between 1992 and 2002.
  • Analysis of patient demographics, clinical presentation, and laboratory findings.
  • Comparison of IgA deficiency prevalence with healthy populations.

Main Results:

  • Out of 91 patients with juvenile parotitis, 23 (28%) had the relapsing form.
  • The median number of recurrent episodes was 5 (range, 2-20).
  • Selective IgA deficiency was identified in 5 patients (22%), a significantly higher prevalence than in the general population (0.3%; P < 0.001).

Conclusions:

  • Recurrent parotitis of childhood is a distinct entity within juvenile parotitis.
  • Selective IgA deficiency is notably more prevalent in children with recurrent parotitis.
  • Further research is warranted to explore the immunologic underpinnings of this condition.

Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
Chronic Pharyngitis01:23

Chronic Pharyngitis

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,...
