Background:Melasma is a common cause of facial hyperpigmentation with significant cosmetic deformity. Although several treatment modalities are available, none is satisfactory.Aim:To compare the therapeutic efficacy and safety of tranexamic acid (TA) microinjections versus tranexamic acid with microneedling in melasma.Materials and Methods:This is a prospective, randomised, open-label study with a sample size of 60; 30 in each treatment arms. Thirty patients were administered with localised microinjections of TA in one arm, and other 30 with TA with microneedling. The procedure was done at monthly intervals (0, 4 and 8 weeks) and followed up for three consecutive months. Clinical images were taken at each visit including modified Melasma Area Severity Index MASI scoring, patient global assessment and physician global assessment to assess the clinical response.Results:In the microinjection group, there was 35.72% improvement in the MASI score compared to 44.41% in the microneedling group, at the end of third follow-up visit. Six patients (26.09%) in the microinjections group, as compared to 12 patients (41.38%) in the microneedling group, showed more than 50% improvement. However, there were no major adverse events observed in both the treatment groups.Conclusions:On the basis of these results, TA can be used as potentially a new, effective, safe and promising therapeutic agent in melasma. The medication is easily available and affordable. Better therapeutic response to treatment in the microneedling group could be attributed to the deeper and uniform delivery of the medication through microchannels created by microneedling.

considerable costs. [1] The prevalence of leg ulcers is well documented to be vary between 0.18% and 1%. [2] The three major causes of lower extremity ulcers are venous, arterial, and neuropathic. Chronic nonhealing ulcers lack the necessary growth factors (GFs) and hence do not heal well. Conventional recombinant GF products, including becaplermin (recombinant platelet-derived GF) have been approved by the Food and Drug Administration for the treatment of chronic wounds. However, the medication is in a liquid form, and, therefore, easily dissipates following wound application. In addition, it is expensive and is unaffordable in developing countries such as India.

Background:Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the legs. They are the major cause of chronic wounds, occurring in 70% to 90% of chronic wound cases. The treatment of venous ulcers also entails substantial costs. Autologous platelet rich plasma (PRP) is a simple office based procedure which helps in enhancing the wound healing by releasing many growth factors like platelet derived growth factors, fibroblast derived growth factors and epidermal growth factors.Aim:To study the efficacy of autologous platelet rich plasma in the management of chronic venous ulcer.Methodology:12 patients with 17 venous ulcers were treated with PRP and treatment outcome was measured by percentage of improvement in area and volume of the ulcer.Results:12 patients with 17 ulcers were treated with PRP. The mean age of the patients was 33.5 years (SD 9.82). 10 were males and 2 were females. The mean duration of the healing of the ulcers was in 5.1 weeks (SD 3.1). The mean percentage improvement in the area and volume of the ulcer was 94.7% (SD 11.12) and 95.6% (SD 10.19) respectively.Conclusions:PRP is safe, simple and effective procedure in treating chronic venous ulcers

Lower extremity ulcers and amputations are an increasing problem among individuals with diabetes. Among diabetes mellitus-related complications, foot ulceration is the most common, affecting approximately 15% of diabetic patients during their lifetime. The pathogenesis of diabetic ulcer is peripheral sensory neuropathy, calluses, oedema and peripheral vascular disease. Diabetic ulcer is managed by adequate control of infections and blood sugar levels, surgical debridement with various dressings and off loading of the foot from pressure. In spite of these standard measures, some recalcitrant non-healing ulcers need additional growth factors for healing. Autologous platelet-rich plasma is easy and cost-effective method in treating diabetic ulcers as it provides necessary growth factors which enhance healing.
