Hemangiomas can present a difficult problem in management. Much controversy exists over whether it is better to watch and wait for natural involution or to be more aggressive and attempt to prevent some of the potential negative sequelae. Different modalities have been employed in the treatment of hemangiomas, including systemic therapy – antiangiogenic drugs, i.e. systemic corticosteroids and α-interferon – and local therapy – surgical procedures, arterial embolization and cryotherapy. Overall, a very conservative approach to therapy has been recommended because of treatment risks, treatment inadequacy and lack of evidence showing superiority over natural involution. Recently laser treatment has been used in the therapeutic approach of hemangiomas. This review discusses the pros and contras of early laser treatment of hemangiomas. For superficial hemangiomas, the flashlamp pumped pulsed dye laser in particular has proven itself in numerous studies. In the treatment of hemangiomas with subcutaneous components, the Nd:YAG laser is the treatment of choice.
This study shows that nonablative 1540 nm fractional laser is a safe and effective treatment for the improvement of scars and grafts after Mohs surgery.
Background: The use of dermoscopy improves the diagnosis of skin cancer significantly in trained dermatologists. However, to evaluate its cost-effectiveness in daily practice, not only sensitivity but also the excision rate is important. Objective: We examined the diagnostic accuracy of cases from a true population-based sample scored by general dermatologists. Methods: One hundred twenty-six dermatologists were randomly assigned to 145 digital cases of lesions detected at a skin cancer screening. This resulted in 4,655 case evaluations using a web application. Accuracy of diagnosis and treatment was correlated with the histological diagnosis or expert opinion. Results: The larger portion (89.7%) of the participating dermatologists reported using their dermatoscope daily. The odds of making a correct diagnosis of melanoma using dermoscopy was 5.38 compared with naked-eye examination (NEE). Dermoscopy increased sensitivity for skin cancer diagnosis from 70.6% to 84.6%, but this was associated with a small but significant decrease in specificity of 3.5%. To detect 1 skin cancer, 5.23 lesions had to be biopsied/excised in this sample and this was not significantly improved by dermoscopic evaluation. Dermoscopy significantly increased the confidence about making a correct diagnosis, especially in seborrheic keratosis, Bowen disease, and melanoma. Conclusions: Dermoscopy significantly improved diagnostic accuracy, the sensitivity of skin cancer detection, and the confidence in diagnosis especially for seborrheic keratosis, Bowen disease, and melanoma. However, this finding was not reflected in a significant reduction in the number needed to excise in this sample.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
