40 subjects will be included to receive 15% paromomycin in aquafilm base twice a day during 20 consecutive days. The lesion will be cleaned , then, a generous amount of the study drug (an amount sufficient to cover the area of the ulcer and the lesion border) will be applied to the lesion and rubbed into the ulcer using a gloved finger by a member of the clinical study staff. After application of the study drug, the patient will be observed for 15 minutes for signs of adverse events. If there are no signs of local toxicity, the area of the ulcer will be covered with extra study drug. For Days 2-20, the study drug will be applied and the lesion covered with a sterile gauze and tape dressing as on Day 1.
20 subjects will be included to receive IL pentamidine [Pentacarinat® Sanofi-Aventis: 30 mg/ml] will administered at a dose of 120 ug (4 ul) per mm2 of lesion area 3 times (on days 1, 3, and 5) as per our previous experience. A small button of Xylocaine® will be applied by means of a thin needle at the four cardinal points of the lesion and then a small gauge (23g) needle will introduce the drug in each cardinal point. The needle will be moved in all directions to infiltrate of whole lesion and surrounding infiltrated area.
