ICP Infections of the Oral Mucosa

Causes of Oral Infections

Can be classified into viral infections, fungal infections, and bacterial infections.

Primary Herpetic Gingivostomatitis

Primary infection with HSV, usually HSV-1, characterized by oral vesicles that break down into ulcers, commonly seen in children.

Recurrent HSV Infections

Reactivation of herpes simplex virus leading to recurrent infections, mainly as Herpes labialis.

Erythema Multiforme

Acute hypersensitivity reaction often caused by herpes simplex and drugs, characterized by target lesions and oral ulceration.

Chickenpox (Varicella)

A primary infection caused by Varicella-Zoster virus, common in children, characterized by an itchy skin rash and oral ulcers.

Shingles (Herpes Zoster)

Recurrent infection of the Varicella-Zoster virus in adults, often presenting with a unilateral rash and oral ulcers.

Oral Candidal Infections

Include acute pseudomembranous candidiasis (thrush), chronic atrophic candidiasis, angular cheilitis, and median rhomboid glossitis.

Thrush

An acute pseudomembranous candidiasis mainly caused by Candida albicans, characterized by white papules or plaques in the mouth.

Denture Stomatitis

Chronic atrophic candidiasis, characterized by inflammation and erythema under dentures.

Angular Cheilitis

Inflammation at the commissures of the mouth, commonly seen in adults, often due to various predisposing factors.

Chronic Hyperplastic Candidiasis

A persistent white patch in the oral cavity that cannot be removed, may indicate malignancy risk.

Aspergillosis

A fungal infection caused by inhalation of spores, with severe manifestations in immunocompromised patients.

Syphilis

A sexually transmitted infection that can cause oral lesions during its various stages, including indurated ulcers in primary syphilis.

Management of Primary Herpetic Gingivostomatitis

Involves supportive care, including hydration, analgesics for pain relief, and antiviral medications such as acyclovir in severe cases. Oral hygiene must be maintained.

Management of Oral Infections

Management includes identifying the causative agent (viral, fungal, bacterial) and applying appropriate treatments. Supportive care is crucial, alongside antiviral, antifungal, or antibiotic therapies as needed.

Management of Recurrent HSV Infections

Involves use of antiviral medications, such as acyclovir, and lifestyle modifications to reduce triggers of reactivation.

Management of Erythema Multiforme

Treatment includes symptomatic relief with antihistamines and corticosteroids, and addressing underlying causes or triggers.

Management of Chickenpox (Varicella)

Supportive care with antihistamines for itching, acetaminophen for fever, and maintaining hydration. Antiviral medications may be considered in severe cases.

Management of Shingles (Herpes Zoster)

Involves antiviral therapy (e.g., acyclovir), pain control, and management of postherpetic neuralgia.

Management of Oral Candidal Infections

Includes antifungal treatments, oral hygiene improvement, and addressing predisposing factors such as immunosuppression.

Management of Angular Cheilitis

Typically involves antifungal or antibiotic treatments and addressing any underlying factors that contribute to its development.

Management of Chronic Hyperplastic Candidiasis

Requires biopsy to rule out malignancy, followed by antifungal therapy and close monitoring.

Management of Aspergillosis

Includes antifungal medications, with consideration for surgical intervention in severe cases or if there is a foreign body.

Management of Syphilis

Involves antibiotic treatment, specifically penicillin, and follow-up to ensure resolution of the infection.

Management of Primary Herpetic Gingivostomatitis

Involves supportive care, including hydration, analgesics for pain relief, and antiviral medications such as acyclovir in severe cases. Oral hygiene must be maintained.
