Fractional Carbon Dioxide (CO) Laser Alone Versus Fractional CO Laser Combined With Triamcinolone Acetonide or Trichloroacetic Acid in Keloid Treatment: A Comparative Clinical and Radiological Study.

Introduction: Keloids are benign fibro-proliferative scarring extending outside the initial wound. Different treatment modalities as intralesional corticosteroid injection, fractional CO laser, and others can be used either as mono or combined therapies.

Objectives: To assess the efficacy of fractional CO laser versus fractional CO laser accompanied with either triamcinolone acetonide or trichloroacetic acid 20% in keloid treatment clinically and radiologically.

Inhibition of angiogenesis as a new therapeutic target in the treatment of lepromatous leprosy.

Background: Angiogenesis was suggested to have a significant role in the pathogenesis of leprosy. However, the benefit of inhibiting angiogenesis in lepromatous leprosy patients has not previously been studied. The purpose of this study was to evaluate angiogenesis in leprosy patients before and after treatment with multidrug therapy (MDT) with and without minocycline.
