Presentation on Vitiligo minigrafting by Professor Koushik Lahiri at shariing his decades of experience and knowledge on the topic. He then goes on to describe the vitiligo mini punch grafting technique, including the necessary instruments and the steps involved in the procedure, with very practical examples as well as an extensive coverage of the side effects. The presentation also includes a video of a vitiligo surgery and the post-operative dressing. Dr. Lahiri emphasizes the importance of follow-up visits and the use of narrowband UVB to achieve complete repigmentation

In this presentation, Professor Rashmi Sarkar talks about melasma, a common hyperpigmentary disorder that affects sun-exposed areas, mostly the face, and occurs more commonly in females. The causes of melasma include genetic influences, sunlight (UVA, UVB, visible light, and infrared radiation), hormonal contraceptives, pregnancy, cosmetics, endocrine factors (especially thyroid dysfunction), and medications. Melasma’s pathogenesis is a complex process that involves epidermal hyper-melanosis, melanocytes, genetic factors, racial factors, hormonal factors, sun exposure, oxidants, antioxidants, and vascular factors. The treatment of melasma is challenging, and the therapeutic options include topical sunscreens, topical hypopigmentation agents, chemical peels, lasers, physical modalities, oral agents, and cosmetic camouflage. Newer demelanizing agents include Soybean trypsin inhibitor, Licorice, Niacinamide, Flavonoids, Silymarin, Oligopeptides, tropical Metformin, Tranexamic acid, Polypodium leucotomos, Proanthocyanidins, and Pycnogenol. Tranexamic acid has stood the test of time as a systemic agent for the treatment of melasma.
