Clinical assessment of disease severity in recurrent aphthous stomatitis.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal diseases in many parts of the world. However, there is very limited published clinical evidence for the therapies used in this condition. This could be partly due to the difficulty in evaluating the efficacy of oral ulcer treatment objectively. In this paper, we present a method for assessing and monitoring the severity of oral ulcers before and after treatment. METHODS: Six ulcer characteristics, number, size, duration, ulcer-free period, site and pain, were used to generate an ulcer severity score (USS). The scores for 223 RAS patients were determined, and 79 were scored again after 3-month therapy with topical betamethasone. RESULTS: The scores for the minor RAS group were between 18 and 43 (mean 29.2 ± 5.3). The mean score in the major ulcers group (range: 28-60, mean 39.9 ± 6.1) was significantly greater than in the minor group (P < 0.001). The herpetiform recurrent ulcers score range was wide (range: 18-57, mean 36.6 ± 8.4). The mean severity score decreased significantly after treatment (P < 0.001). CONCLUSIONS: The USS was indicative of the disease activity in recurrent oral ulceration. It helped in assessing the efficacy of therapy, as the change in the numerical score reflected the change in ulcer severity in response to treatment. This tool may well prove to be of value in clinical management, research and in clinical trials.

Herpetic gingivostomatitis in otherwise healthy adolescents and young adults.

The purpose of this study was to review and analyze the records of herpes simplex infections from a specialist Oral Medicine clinic in Iceland, to investigate the clinical impression that the age of patients experiencing initial infection with this virus was higher than expected and that the character of the clinical picture of the disease had changed. Records of patients with herpes infections attending the Oral Medicine clinic covering a 3-year period were examined and the clinical and virological data analyzed. Diagnosis was based on clinical appearance, history, and viral identification with culture or detection of viral DNA by means of the polymerase chain reaction. Records of 60 patients (34 female) were included in the study (mean age, 23.1 years; range, 2 68 years). No patients were known or suspected to be positive for human immunodeficiency virus, none was known to be immunocompromised, and 38 patients (mean age, 16.6 years; 21 female) were diagnosed as having primary herpetic gingivostomatitis. Eighteen patients (mean age, 36.2 years; 11 female) had lesions of recurrent herpes simplex infection present on the oral mucosa. Primary infection with herpes simplex virus was more common in young adults than had been expected. Recurrent infections appeared on the oral mucosal even in otherwise healthy patients, and the clinical course of these infections in this age group sometimes followed a more severe course than that seen in young children.
