    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.
