A Potential Alternative Treatment for Vitiligo: An Observational Study on Tacrolimus 0.3% Lotion.

Vitiligo is a complex multifactorial disorder of depigmentation affecting 0.5 to 2% of the world's population without specific gender or racial prevalence.1 Though no treatments are FDA approved to repigment vitiligo, topical medications along with phototherapy alone or in combination remain the mainstay of therapy. While Janus Kinase inhibitors and other agents are in development, current topical options are mainly limited to steroid formulations of various potencies or immunomodulatory steroid-sparing agents such as tacrolimus 0.03% or 0.1%.

Durapore vs. Hy-Tape for securing endotracheal tubes during general anaesthesia: a prospective randomised controlled non-inferiority trial.

INTRODUCTION: Adhesive tape is commonly used to secure endotracheal tubes (ETT) during general anaesthesia. Although a variety of adhesives are used in practice, few studies have investigated the likelihood of different adhesives in producing facial skin injury. Given that differences in cost exist between adhesives that are often used interchangeably, it would be prudent to use the most economical option. MATERIAL AND METHODS: A single-centre, prospective, randomised controlled non-inferiority trial of patients undergoing general anaesthesia with an ETT was conducted. Patients were randomised in a blinded fashion to use Durapore (DP) on either the right or left side of the face to secure the ETT, with Hy-Tape (HT) on the contralateral side. Skin photographs were taken prior to tape application and following tape removal. These were evaluated by three dermatologists to determine presence or absence of facial skin erythema, scaling, oedema, and tearing. Differences were compared using McNemar's test. For outcomes analysis, a non-inferiority margin of 20% difference was used with respect to the 95% CI. RESULTS: Among 112 patients, 33.0% were male, with a mean (SD) age of 55.6 (15.9) years. Comparing DP vs. HT, noninferiority was demonstrated in the patients with skin erythema (1.8% difference, 95% CI: -5.6 to 9.2, P = 0.79), oedema (3.6% difference, 95% CI: -2.8 to 10.0%, P = 0.34), scaling (5.4% difference, 95% CI: -4.1 to 14.8, P = 0.31), and tearing (0.9% difference, 95% CI: -5.2 to 7.3, P > 0.99). CONCLUSIONS: There is a non-inferior difference in the proportion of patients with facial skin erythema after use of DP vs. HT to secure the ETT.

Sterile pustulosis as a rare side effect of fractional bipolar radiofrequency device: a case report.

Fractional bipolar radiofrequency technology is associated with minimal downtime and rare side effects and become an increasingly popular tool in aesthetic dermatology practices. There is limited damage to the epidermis, and side effects such as post-inflammatory hypo/hyperpigmentation are rare. Transient erythema, edema, crusting, and persistent inflammatory papules have been previously reported. We report a rare case of sterile follicular pustulosis following treatment with bipolar fractional radiofrequency (eTwo technology). To the best of our knowledge, this unusual side effect has never been reported.

Response to ustekinumab in three pediatric patients with alopecia areata.

Alopecia areata (AA) is relatively common and can have a significant impact on quality of life, especially in a pediatric population. Currently available treatments are often ineffective or have poor safety profiles. Recent studies have highlighted the importance of the Th1 pathway in the pathogenesis of AA, suggesting ustekinumab as a treatment modality for this disease. We present three pediatric AA patients who demonstrated hair regrowth after initiating ustekinumab.

JAK-STAT signaling pathway inhibition: a role for treatment of various dermatologic diseases.

Cutaneous inflammatory conditions such as psoriasis, atopic dermatitis, alopecia areata, vitiligo, and connective tissue diseases often remain a challenge to treat. Although there is an in-depth understanding of the clinical presentation of these diseases, much less is known regarding the pathophysiology. This has limited the effective treatment options for patients. A more detailed understanding of the pathogenesis of each disease will lead to newer targeted medications with less morbidity. Though there are different pathways involved in these diseases, the Janus Kinase (JAK)-Signal Transducer and Activator of Transcription proteins (STAT) signaling pathway is common to them all. Therefore, this review article endeavors to substantiate the immunopathology and clinical utility of the JAK inhibitors as treatments for different chronic inflammatory diseases of the skin.

JAK-STAT signaling pathway inhibition: a role for treatment of discoid lupus erythematosus and dermatomyositis.

BACKGROUND: Discoid lupus erythematosus (DLE) and dermatomyositis (DM) are inflammatory autoimmune diseases that manifest primarily in the skin but can be linked to systemic complications. Although there is an in-depth understanding of the clinical presentation of these two diseases, much less is known regarding the pathophysiology. This has limited the effective treatment options for patients. OBJECTIVE: An understanding of the pathogenesis of each disease in greater detail will lead to newer targeted medications with less morbidity. This review article endeavors to substantiate the use of new treatments which target the JAK-STAT pathway while elaborating on the immunopathology as well. METHODS: PubMed was searched for relevant review articles, case reports, case series reports, randomized clinical trials (RCTs), basic science articles. Appropriate key terms and MeSH terms were utilized in the search. Clinicaltrials.gov was used to find relevant and current clinical trials being conducted in DLE and DM patients. RESULTS: A review of the literature supports the proposal that though there are likely many components and pathways involved in the destruction of keratinocytes, the Th1 cell immune response and specifically the JAK-STAT signaling pathway is common to both DLE and DM. CONCLUSION: Although further study is needed to determine the efficacy and benefits of JAK inhibitors over conventional therapy, these medications should be considered in refractory cases.
