Background: A large proportion of the population is at sometime affected by androgenic alopecia. Current therapies consisting of minoxidil or finasteride are often the first choices for treatment. These regimens are limited by their efficacy, side-effect profiles, and often lengthy treatment courses. Low level laser/light has shown to be relatively effective and safe for the treatment of hair loss, and a number of products are currently available to consumers. Recently, fractional lasers have been examined as treatment options for androgenic alopecia. The mechanism of action of these minimally invasive resurfacing procedures is thought to be 2-fold. First, the microscopic injuries created by these treatments may induce a favorable wound healing environment that triggers hair growth. Alternatively, disruption of the stratum corneum allows for improved transdermal passage of well-established therapeutic drugs to the hair roots. Methods: A literature review was performed to evaluate the efficacy of these emerging treatments on hair regrowth. Results: Nine original studies examining the effect of fractional lasers on hair growth in androgenic alopecia have been reviewed. Conclusions: Preliminary evidence suggests that fractional laser therapies have a positive effect on hair regrowth; however, most of the literature is limited to case reports, and small prospective and retrospective series. Further studies, in the form of well-designed randomized controlled trials, are necessary to evaluate the efficacy, safety, and optimal treatment courses.

Alopecia areata (AA) affects approximately 2.1% of the population, with women being affected more often than men. Current therapies consisting of topical corticosteroids or intralesional injections are often the first choices for treatment, but are limited by unsatisfactory outcomes or risks to patients. Recently, fractional lasers and microneedling, with or without the addition of topical agents, have been examined as treatment options. A literature review was performed to evaluate the efficacy of fractional lasers in the treatment of AA. A total of six fractional lasers and two microneedling studies consisting of small prospective and retrospective studies, and case reports were reviewed. The number of trials and participants are limited, but evidence suggests that fractional lasers and microneedling may be effective therapeutic approaches when coupled with topical agents. Larger studies are required to better understand the effects of these treatment modalities for AA.

The COVID-19 pandemic has disrupted the lives of billions of people globally. Some medical systems continue to be overburdened due to the viral illness leading to incredible public health challenges domestically as well as abroad. However, with vaccination distribution increasing globally, many are pushing for a return to some form of normalcy. In the medical community, some are weighing the risks of returning to global health missions and considering protective strategies to minimize risk of viral spread. Here we describe our experience in returning to an annual burn reconstruction mission in a low- and middle-income country. We have successfully carried out a return surgical mission trip. Our team of ten individuals was able to perform over 75 procedures on 25 pediatric patients in four operative days. We applied a variety of protective strategies and altered mission protocol to limit exposure and transmission risk while focusing heavily on education and training Additionally, we increased the use of telemedicine and eliminated typical in person clinic visits. We increased operative complexity to increase impact while limiting patient exposure. Rigorous perioperative safety and follow-up protocols were implemented. The increased use of telemedicine, reduction of in person visits, emphasis on education, and implementation of safety and follow-up protocols have led to an improvement in efficiency, safety, and accountability. Our adaptations have provided guidance on responsibly resuming surgical outreach missions, with changes that are likely to endure beyond the COVID-19 pandemic.
