Introduction: This study addresses the gap in research comparing the effectiveness between home and in-office narrowband ultraviolet B (NB-UVB) phototherapy for the treatment of mycosis fungoides (MF). Elderly and disabled patients with this condition disproportionally lack access to home units due to insurance denial.

Materials and methods: A retrospective review included patients diagnosed with MF or Sezary syndrome who underwent either in-office or home UVB between 2016 and 2023. Eighty-four patients used home NB-UVB, while 75 used in-office. Clinical characteristics, treatment response, and access were evaluated.

Results: Overall, there was no significant difference in response rates between home and in-office NB-UVB phototherapy. Subgroup analysis based on adjuvant treatment revealed a significant difference in clinical response rates for patients using NB-UVB with topicals (p = 0.008) and NB-UVB with multiple systemic therapies (p = 0.04). Financial and time constraints were the most common cause of treatment discontinuation for in-office patients (28%).

Conclusions: The effectiveness of home NB-UVB treatment is comparable, if not superior, to in-office treatment, likely attributed to treatment ease in access and compliance. Medicare and other health insurance companies should expand coverage to include home-based phototherapy for patients with MF, a potentially fatal cancer with a relative paucity of effective alternate therapies.

Background: Cutaneous graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplantation. Phototherapy has been used to treat cutaneous GVHD, but data on its safety and efficacy are sparse.

Aim: Review the current medical literature regarding the efficacy, dosing, and safety of various types of phototherapies for the treatment of cutaneous GVHD.

Methods: A systematic review of PubMed, Embase, Cochrane, and ClinicalTrials databases was performed. Publications were screened according to the PRISMA guidelines. Exclusion criteria comprised case reports and case series reporting less than five patients, review articles, and articles not published in English.

Results: A total of 28/1304 (2.5%) studies were included. Fifteen studies (n = 267 patients) focused on psoralen and ultraviolet (UV) A (PUVA), in which 65.5% of patients received concomitantly other systemic treatments. The response rate was 89.9%, with a mean of 33.2 treatments. Adverse events were recorded in 54% but were mainly mild. Eight studies, encompassing 95 patients, focused on narrow-band (NB) UVB. A response was observed in 94%, with a mean number of 26 treatments and 8.6% adverse effects. UVA1 was reported in six studies (n = 132 patients). A response was recorded in 89.3% with a mean of 26.2 treatments. Adverse events were noted in 70.1%, with a discontinuation rate of 10.9%. It should be noted that adverse events were recorded during the follow-up period of the studies, which varied significantly, ranging from no follow-up to 31 months.

Conclusions: Current data regarding the use of phototherapy for the treatment of cutaneous GVHD are based on retrospective studies and case series. The present report advocates the use of one of the three modalities of phototherapy as an effective and safe adjunctive treatment for cutaneous GVHD, especially NB UVB phototherapy.

Background: Previous studies have noted the link between rosacea severity and quality of life, but there is limited understanding of how disease perception impacts these aspects. Additionally, sun exposure is identified as a common trigger for rosacea flare-ups, emphasizing the importance of sun protection practices in managing the condition. This cross-sectional study aims to fill the gap in the literature by investigating the relationship between clinical severity, disease perception, quality of life, and sun protection behaviors in rosacea patients.

Methods: Questionnaires assessing the quality of life, illness perception, sun protection behaviors, sun protection decisional balance, and its potential predictors were completed by 120 rosacea patients and 120 controls.

Results: Patients exhibited a higher prevalence of sun protection behaviors than the control group (24.15 ± 5.76 vs. 17.63 ± 5.56, p < 0.001) and demonstrated greater determination in adhering to sun protection practices (13.43 ± 2.37 vs. 9.40 ± 3.09, p < 0.001). Hierarchical linear regression analyses showed that quality of life was related to clinical severity, illness perception (consequences, illness coherence, emotional representations), causal attribution (risk factors, immunity), and sun protection decisional balance variables (R² = 0.45, F = 7.39, p < 0.001). Also, the perceived pros and cons of sun protection behaviors were predicted by illness perception (treatment control), causal attribution (risk factors, immunity, chance/accident), and quality of life variables (R² = 0.24, F = 2.59, p = 0.004).

Conclusions: Providing more information to rosacea patients can improve their disease perception and quality of life, increasing adherence to sun protection behaviors.

Background: Post-acne scars are a common sequela of acne, especially prevalent among young people. Delayed treatment not only affects self-perception of beauty but also affects the mental health of patients.

Objective: This study aims to investigate the clinical efficacy of microneedle fractional radiofrequency (MFR) combined with botulinum toxin A (BoNT/A) in managing post-acne scars.

Methods: This retrospective study involved 63 adult patients with post-acne scars, divided into two groups: group 1 (n = 30) and group 2 (n = 33). Group 1 received treatment with MFR combined with transcutaneous delivery of BoNT/A, whereas group 2 received treatment with MFR alone. The study observed the clinical outcomes in both groups.

Results: Based on experimental analysis, the combination of MFR with transcutaneous delivery of BoNT/A demonstrated superior clinical efficacy compared with group 2. There were no significant differences in baseline data or treatment-related pain and adverse reactions between the two groups. However, group 1 exhibited a higher effectiveness rate, lower ECCA score after treatment, higher satisfaction levels, and statistically significant differences compared to group 2.

Conclusion: MFR combined with transcutaneous delivery of BoNT/A represents an effective and safe alternative for treating acne scars with minimal side effects and complications.

Summary statement: Post-acne scars are a common sequela of acne and combination therapy proves beneficial. Microneedle fractional radiofrequency (MFR) combined with transcutaneous delivery of BoNT/A can be considered an effective and safe alternative for the treatment of acne scars with minimal side effects and complications. It works together through microneedles, radiofrequency, and botulinum toxin. MFR combined with transcutaneous delivery of BoNT/A is based on the direct action of MFR on acne scars and the use of microneedle to create a transient skin microchannel, facilitating BoNT/A penetration into the skin.

Background: Tinted sunscreens not only shield against UV rays but also provide protection against visible light, as opposed to traditional sunscreens. Universal tinted sunscreens are marketed to complement all skin tones.

Objective: To assess color match and subject satisfaction for 7 universal tinted sunscreens across various price ranges in all Fitzpatrick skin phototypes (SPT).

Methods: Products A-G were applied at concentrations of 1 and 2 mg/cm² on the dorsal arms of 30 subjects spanning SPT I-VI. Photography, colorimetry, and subject and investigator surveys were utilized to determine color match.

Results: Using colorimetry analysis at the recommended 2 mg/cm² concentration, two of seven products were identified as suitable matches for SPT I-II, while six out of seven were determined to be a good match for SPT III-IV. However, only one product was found to be a good match for SPT V-VI at the recommended concentration according to colorimetry results.

Conclusion: Universal tinted sunscreens do not provide an adequate color match for all skin phototypes, especially for individuals with very fair or very dark skin tones.
