Background: Acne scars poses a significant psychosocial morbidity in this era of aesthetic concern. Acne scars can be classified into three types-atrophic, hypertrophic & keloidal. Atrophic acne scars are the most common type. Many treatments are available for treating post acne scars. Platelet-rich plasma (PRP) may be useful in atrophic scars by promoting collagen deposition. Microneedling also releases growth factors, which initiates a cascade of wound healing resulting in collagen deposition. Hence, microneedling and PRP should act synergistically to improve acne scars. Objective: To assess the efficacy of microneedling with topical autologous platelet rich plasma in the treatment of acne scars. Material and Methods: The study enrolled 20 cases of acne scars. Microneedling with topical PRP was applied over acne scars. They received 4sequential treatments with an interval of 4 weeks between each session. At first visit, scars were graded according to Goodman and Baron's qualitative acne scar grading system. After 4 sessions objective assessment of physician scores of improvement were determined by Goodman and Baron's qualitative &quantitative acne scar grading system. Results: Male female ratio was 0.43:1. After completion of 4sessions, qualitative assessment revealed reduction by 3 grades in 12 patients (60%) and Quantitative assessment showed 8 patients (40%) with very good reduction. Photographs were taken at each visit and compared. Conclusion: Microneedling with topical PRP was safe, superior and efficacious in treating acne scars.

BACKGROUNDChronic dacryocystitis is one of the most common cause of epiphora due to insufficient drainage. Dacryocystogram by linear tomography with Omnipaque precisely helps us to determine the site of Nasolacrimal Duct (NLD) block. It helps us to arrive at the indications of surgery and also to plan the type of surgery that has to be performed.
