Ulceration, large grey-blue ovoid nests, multiple grey-blue globules, maple leaf-like areas and arborizing telangiectasia, which are specific dermoscopic features for the diagnosis of pigmented BCC, were found to correlate with their histopathologic counterparts. In conclusion, dermoscopy can be described as a valuable tool for the diagnosis of pigmented basal cell carcinomas.

To investigate the effect of a-tocopherol (vitamin E) on fracture healing in rabbits, two groups of 10 rabbits were either injected with a-tocopherol (treated) or untreated (controls). The right femurs of both groups were fractured, and the treated group were injected intramuscularly with 20 mg/kg a-tocopherol daily for 5 days starting on the day of fracture. After 21 days, histological sections of the fractured region were examined and scored. Fracture healing had progressed further in the a-tocopherol group than in the control group. A statistically significant difference between the histological grading of fracture healing in the two groups was found. This difference may result from an antioxidant (a-tocopherol) effect on free oxygen radicals in the fracture area. We conclude that a-tocopherol may affect fracture healing favourably and might be useful as a therapeutic agent in clinical fracture management.

It has been determined that BTX-A injection reduces wound and graft contraction, and also, it is effective on reducing the amount of sebaceous cells and hair follicles.
