RESUMO
AIM: Low molecular weight derivatives of heparin have been recently suggested for the treatment of different diseases including oral lichen planus (OLP) due to their effectiveness and limited side effects. However, no studies have concerned the effectiveness of these agents in the treatment of recurrent aphthous stomatitis (RAS). The present study then aimed to assess this effectiveness in vivo. METHODS: Included were 30 RAS patients consecutively referred to our centers without any systemic diseases. The ulcers were examined in terms of size and number. Recurrence intervals were recorded by the patients. 1 U/0.002 mL enoxaparin was injected subcutaneously (3 mg). Injections were repeated once a week for 8 weeks. The patients were followed monthly for three months. To determine the level of pain, Visual Analogue Scale (VAS) from 0 to 10 was used. The data were statistically analyzed to determine the difference between the number, size, and pain using Wilcoxon test. RESULTS: It was shown that 8-stage injection of enoxaparin is associated with significantly reduced number, size, recurrence intervals, and the intensity and duration of pain of the lesions in 21 males (70%) and 9 females (30%) of the present study. CONCLUSION: According to the limitations of the present study, systemic Enoxaparin seems successful in reducing the number, size, recurrence frequency and the duration of pain and discomfort in RAS patients without significant side effects.

Ninety-six patients with a clinical and parasitological diagnosis of cutaneous leishmaniasis were recruited to a comparative randomized clinical trial evaluating the efficacy of topical paromomycin vs. weekly intralesional injections of meglumine antimoniate. The patients were randomly divided into two treatment groups: one group was treated with topical paromomycin ointment and the other with intralesional meglumine antimoniate. Treatment was continued in both groups until complete recovery occurred (defined as healing in less than 2 months with no residual scar or relapse for up to 1 year post treatment). Treatment failure was defined as an increase in the number and size of pre-existing lesions or untoward side-effects. The maximum treatment period was 3 months. The patients were followed up for 1 year. The results showed that intralesional meglumine antimoniate led to 41.7% complete recovery, However, topical paromomycin gave a lower cure rate of 16.6% (P < 0.05). Treatment failure was observed in 39.7% of the group receiving intralesional meglumine and in 72.9% of those on topical paromomycin (P < 0.05). This study indicates that intralesional meglumine antimoniate is superior to topical paromomycin in the treatment of cutaneous leishmaniasis.
