New treatments on the horizon
Emerging therapies are showing impressive efficacy and good tolerability, according to one dermatologist.
Alternative to skin grafting
There is a growing burden in wound management. Stem cells will be instrumental in the development of skin substitutes. Novel hydrogel promotes skin regeneration in in vivo experiments.
Protocol for injecting fillers gives more predictable results
Partitioning the face into different units and injecting filler in specific locations is a method to attaining a rejuvenated face that looks relaxed and natural.
Burn depth difficult to determine with the naked eye
Visual assessment of a burn injury is insufficient to judge the depth of a burn; hypertrophic scars left by burn injuries are increasingly being treated with lasers with impressive results.
Acne responds to energy-based therapies
Energy-based treatments can be used on their own or in conjunction with medical treatments to address chronic dermatological conditions like melasma, acne, and vitiligo.
Knowledge of skin microbiome provides insights into dermatological conditions
Direct sequencing data, together with culture data, supplies researchers with information about communities of bacteria and fungi on the skin.
Make smart device purchases
Conducting an evaluation in the marketplace and looking to independent sources of information are steps that need to be taken before buying any energy-based device to be used in cosmetic dermatology.
Cumulative dosing of isotretinoin should not follow strict range
Cumulative dosing of isotretinoin has followed a reference range of 120 to 150 mg/kg, but there is an absence of strong evidence supporting this recommendation, pointing to the need for clinicians to treat their patients to achieve clearance of acne rather than adhere to this range.
Appreciating the role of microbial communities on the skin
Microbial colonization in the development of inflammatory conditions and immune-mediated conditions is a hot research topic, and new dermatologic therapies can potentially result from greater understanding of the role of microbial communities on the skin and in the gut.
Restoring the balance: skin microbiome in atopic dermatitis
Research has demonstrated that staph aureus is in increased supply on the skin of atopic dermatitis patients coupled with less overall diversity in the number of bacteria on their skin, suggesting therapies that achieve balance in the skin microbiome could help to manage atopic dermatitis.
