Recognize common pediatric oral pathology lesions Understand the recommended treatment for lesions of the oral mucosa – 3 y.o. female with painful, swollen gums for over 1 week duration – Systemic signs include fever, malaise and lymphadenopathy – Gums bleed easily – Gingival papilla appear blunted Differential diagnosis: A. Primary herpetic gingivostomatitis B. Aphthous stomatitis C. Hand foot and mouth disease Causative agent is Herpes Simplex Virus Type I Findings include vesicles on the mucosa, tongue and gingiva that rupture to form large painful ulcers Lesions are accompanied by fever, malaise, cervical lymphadenopathy and anorexia Lesions may be located on keratinized or non- keratinized tissues 20-35% of children are infected by 5 years of age Transmitted via saliva Diagnosis of HSV infection is usually made by a combination of clinical findings and by sampling an active lesion and testing it for the presence of the virus by PCR, direct fluorescent antibody methods, or viral culture. Difficult to perform thorough examination due to child’s discomfort and behavior Initially no well-defined lesions Language barrier/ phone interpreter not ideal Child had developmental delay and was non- communicative Symptoms were present for at least a week and not improving After 2 days as in-patient, lesions were visualized Therapy Symptoms generally last 7-10 days Treatment should be palliative Bed rest and antipyretics (acetaminophen or ibuprofen) Maintain fluids Young children may require hospitalization and I.V. fluids Contraindications: antibiotics and steroids For primary gingivostomatitis, acyclovir may be used. Treatment should start within 3 days of symptoms Duration of pain is reduced significantly Time to loss of crust is reduced by 1 day Dosage: 15 mg/kg by mouth five times daily for 7 days P. Chayavichitsilp et al, Pediatr Rev 2009;30;119-130 Alter SJ et al, Curr Probl Pediatr Adolesc Health Care 2015;45:21-53 Red, swollen gums, perioral lesions Ulcerations on tongue and lips Symptoms may vary from one child to another PRIMARY HERPES PRIMARY HERPES May be associated with erupting tooth. Tissues in the mouth that are keratinized include: Hard palate, attached gingiva Lips, dorsal surface of tongue and skin around mouth Non-keratinized tissues include: Ventral surface of tongue, buccal and labial mucosa, soft palate – 8 y.o. male with painful vesicles and ulcers on his palate 4 days duration – No systemic manifestations – Otherwise in good health with no allergies and no medical diagnoses – Ulcerated lesions also present on fingers Painful Vesicles on palate The Differential Diagnosis includes: A. Recurrent herpes C. Aphthous stomatitis D. Hand foot and mouth disease Painful vesicles and ulcers Often in clusters Occurs on keratinized tissues Recurs in same location – often triggered by cold, sunlight or stress May have mild flu-like symptoms Precautions should be taken to prevent spread of infection to susceptible individuals such as infants, and immunocompromised. 1% penciclovir cream 6 times daily at first sign of symptoms and then every 2 hours while awake for the next 4 days For children over 12 years and adults, alternative therapies are valacyclovir (2000 mg by mouth twice daily) and famciclovir (1500 mg by mouth as a single dose). Short-term (1 to 3 days), high-dose acyclovir or valacyclovir regimens are promising therapies for both genital and orolabial recurrent HSV infections. Spruance SL, Jones TM, Blatter MM, et al.

A. Erythema multiforma B. Recurrent herpes C. Primary herpes D. Aphthous stomatitis Idiopathic Acute onset No systemic manifestations Familial tendency Single or multiple lesions Painful Self-limiting Occurs on non-keratinized tissue 30-40% prevalence Higher SES more commonly affected Immune system dysfunction Dx is based on clinical presentation If frequent and severe, rule out systemic disease Sodium lauryl sulphate may induce ulceration in some patients Ship, JA Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996 Feb;81(2):141-7.
