Study Notes
Infections of the Oral Cavity and Salivary Glands
- Common infections include oral thrush (candidiasis), herpes gingivo-stomatitis, herpangina, hand-foot-and-mouth disease, Vincent’s angina, and dentoalveolar infections.
Oral Candidiasis (Oral Thrush)
- Caused by opportunistic infection from Candida species; prevalent in individuals with compromised immunity (e.g., diabetes, HIV, steroid therapy, newborns, denture wearers).
- Clinical features: White adherent patches on buccal mucosa or hard palate, red, sore surrounding mucosa, potential for confluent curd-like pseudomembrane.
- Diagnosis: Scrapings/swabs from lesions, Gram stain, and culture on Sabouraud's agar.
- Treatment involves topical antifungal agents like nystatin, miconazole lozenges, and clotrimazole.
Herpes Gingivo-Stomatitis
- Caused by Herpes simplex virus (commonly HSV-1, rarely HSV-2); primarily affects children aged 6 months to 6 years.
- Clinical features: Abrupt onset with high fever, headache, malaise, irritability, bilateral lymphadenopathy, and oral lesions that appear as coalescing vesicles leading to painful ulcers.
- New lesions may develop for 3-5 days; ulcers typically heal within 10-14 days.
- Pathogenesis involves targeting epithelial cells, resulting in vesicle formation, ulceration, and potential latency of the virus.
Herpangina
- Acute febrile illness characterized by small vesicular lesions in the posterior oropharyngeal area, caused by Coxsackievirus A.
- Common symptoms: Abrupt fever, sore throat, anorexia, dysphagia, vomiting; vesicles on the fauces, uvula, tonsils, and tongue.
- Mainly occurs in small children; transmitted via fecal-oral, respiratory droplets, and direct contact.
- Diagnosis includes clinical history, stool specimens, and swabs; treatment focuses on symptomatic relief.
Hand-Foot-and-Mouth Disease
- Caused by Enterovirus 71 and Coxsackievirus A16; highly contagious among infants and young children, particularly in nursery settings.
- Initial symptoms resemble common illnesses: fever, headache, malaise; leads to painful red blisters in the oral cavity (throat, tongue, gums) and on palms, hands, and soles.
- Clinical progression includes development of oral ulcers, potential CNS involvement, and abdominal discomfort.
- Prevention emphasizes good hygiene practices like hand washing.
