Fractional CO2 laser and adjunctive therapies in skin of color melasma patients.

Background: Ablative lasers have long been considered an unfavorable option for melasma in patients with skin of color and continue to be underutilized. Objective: To evaluate the safety and outcomes of ablative fractional CO2 lasers on refractory melasma in patients with skin of color. Methods: A retrospective chart review of 12 patients from a single-center dermatology clinic. The study included refractory melasma patients receiving ablative fractional CO2 laser therapy alone or with laser toning and/or tranexamic acid (TXA). A validated modified Melasma Area and Severity Index (mMASI) scoring scale was used to assess disease severity at baseline and approximately 1 month after each treatment session. Results: Among the 12 patients, 41.7% patients showed >50% reduction in mMASI scores with 33.3% of patients showing statistical significance (P < .05). The CO2 laser therapy with the TXA cohort showed the largest decrease in the mean mMASI scores and the CO2 laser with laser toning showed the lowest decrease in scores. Patients who started on oral TXA earlier, after their initial ablative laser session, showed better clinical improvement. Limitations: Retrospective study design with short follow-up period and a small sample size. Conclusion: Ablative CO2 laser treatment may be a reasonable option for refractory melasma in patients with skin of color, though future research is needed.

Assessment of diversity in skin colour in dermatology medical education resources.

One hundred and fifty-three patient images from the general resources and 3583 images from Dermatology were evaluated. The majority of images were Fitzpatrick Type II (54%), followed by Type III (27%). Our findings demonstrate the lack of skin diversity continues across many medical school resources, with fair skin (Fitzpatrick Type II) accounting for the majority of images.

Representation of Fitzpatrick skin type in dermatology textbooks compared with national percentiles.

As time progresses, more patients with skin of color will be seen by dermatologists. To meet the needs of the ever-changing population, medical education needs to analyze how residents are trained in recognizing dermatological disorders in patients with skin of color. The aim of this study was to analyze dermatology textbooks to evaluate how well skin of color patients are represented compared to the current national distributions. The most common skin types depicted in the textbooks were Fitzpatrick skin types II and III, whereas the least common skin types depicted were skin types V and VI. There was a significant difference between a national distribution of skin types when compared to photographs in each of the textbooks (P<0.001). These findings emphasize the need to better represent patients with skin of color in medical textbooks.

Cultural aspects in the treatment of patients with skin disease.

As the cultural distance between patient and physician widens, so does miscommunication. Negotiation between the belief systems of the physician and the patient may create a therapeutic environment of mutual trust and respect that increases the possibility of successful clinical outcomes.
