A Clinical and Dermatoscopic Perspective of the Efficacy and Safety of Erbium: YAG Laser Ablation Versus 50% Trichloroacetic Acid for the Management of Xanthelasma Palpebrarum.

Xanthelasma palpebrarum (XP) is a benign cosmetic condition. Although the role of CO2 laser is well described, there are only a few studies on Erbium: YAG in XP. Similarly, trichloroacetic acid (TCA) is commonly used in XP. However, there are only a few studies comparing these modalities in the treatment of XP. Aim: To evaluate the effectiveness and safety of Erbium: YAG laser and 50% TCA in the treatment of XP with the role of dermoscope in the evaluation of lesions. Materials and Methods: A total of 20 subjects were randomly allocated into two groups: group A (TCA) and group B (laser). All patients were subcategorized into three grades viz. I (mild), II (moderate), and III (severe) using a self-devised scoring system. Results: About 25% and 70% of patients achieved complete clearance in groups A and B, respectively (P = 0.017). The rate of recurrence was 40% and 15% in groups A and B. Dyspigmentation and erythema were the most common side effects. Pretreatment dermoscopic evaluation of the lesion showed a network of brown streaks on a background of a yellowish structureless area and was used to assess the area and margins of the lesion where the adipose tissue was found during the procedure and serial assessment of the lesion.

A split-face study comparing the efficacy and tolerability of erbium YAG laser and 70% trichloroacetic acid in facial seborrheic keratosis.

Introduction: Seborrheic keratosis (SK) are benign lesions with cosmetic concerns. Role of TCA and erbium YAG laser has already been described individually in the literature. However, there is a scarcity of data on the comparative evaluation of these two modalities in SK. Aim: The aim of this study was to compare the efficacy and safety profile of Erbium YAG laser ablation with 70% TCA for the treatment of facial SK. Materials and Methods: A total of 50 cases of facial SK were included in the study. Group A included SK lesions on the right side of face treated with Erbium YAG laser ablation while Group B included SK lesions on the left side of face treated with topical 70% trichloroacetic acid. Repeated sessions of laser and TCA application were given at 2-week intervals till cure was achieved or up to a maximum of three sessions. Grading of response to treatment was assessed as complete response (100% clearance), partial response (>50 to 99% improvement), and inadequate or no response (<50% improvement). Results: Complete clearance was observed in 40 (80%) and 29 (58%) cases in Groups A and B, respectively. There was a statistically significant difference in clearance rates between the two groups (P = 0.019). Number of sessions was significantly lesser in laser group (mean ± SD = 1.24 ± 0.43) than in the 70% TCA group (mean ± SD = 1.88 ± 0.79) (P = 0.001). Statistically significant lesser downtime was observed in group A (P = 0.001). Patient satisfaction rate was much higher in group A. Hyperpigmentation was more common in group B (TCA). Conclusion: Although both the treatment modalities achieved good results, erbium YAG laser ablation showed superior results than 70% TCA with better patient satisfaction rates but more downtime. Also, no major adverse effects were observed in the two groups.

Efficacy of autologous platelet rich plasma with subcision vs platelet rich plasma with microneedling in atrophic acne scars: A single-center, prospective, intra-individual split-face comparative study.

Background: Severe post-acne scarring has been implicated as a cause of considerable psychological distress, mainly among adolescents. Subcision and microneedling are cutting-edge treatment options available nowadays. Aim: In this study, we aimed to compare the efficacy of microneedling with platelet-rich plasma (PRP) against subcision with PRP in treating atrophic post-acne scars in a split-face study design. Materials and Methods: Fifty patients with atrophic post-acne facial scars were included in this prospective interventional study. Group A included the left side of the face managed by microneedling with PRP and group B included the right side of the face that was subjected to subcision with PRP. Results were assessed based on Goodman and Baron qualitative and quantitative grading. Results: In our study, at the end of the treatment, on the left side, 5 (10%) had 1 grade of improvement showing good response, 35 (70%) had 2 grades of improvement showing very good response, and 10 (20%) had 3 grades of improvement showing excellent response. On the right side, 1 (2%) patient had no improvement in acne grade showing poor response, 9 (18%) had 1 grade of improvement showing good response, 25 (50%) had 2 grades of improvement showing very good response, whereas 15 (30%) had 3 grades of improvement showing excellent response. Conclusion: Till date, apart from ours no other study has compared the two modalities head-to-head with adjuvant PRP in both groups. Although both modalities showed statistically significant results individually, there was no significant difference in qualitative improvement of acne scars between the two groups.

The Impact of Tofacitinib on Quality of Life in Patients with Moderate-to-Severe Psoriasis- An Observational Study.

Background: Global phase III trials have established the effectiveness and the safety profile of 5 and 10 mg twice-daily regimens of Tofacitinib for the management of psoriasis. Aims and Objectives: This study was aimed at assessing the improvement in quality of life in patients suffering from moderate-to-severe psoriasis following 12-week Tofacitinib therapy. Materials and Methods: 50 adults with moderate to severe plaque psoriasis enrolled with informed consent. Tofacitinib was given orally for 12 weeks, as 5 mg or 10 mg twice daily based on weight. Improvement in PASI and DLQI was recorded. Results: We observed a statistically significant improvement in PASI (p-value < 0.001) and DLQI (p-value < 0.001) following Tofacitinib therapy. The 3 domains of DLQI with the most significant improvement were symptoms and feelings (items 1 and 2) (p-value-0.001), daily activities (items 3 and 4) (p-value-0.0001), and treatment (item 10) (p-value-0.0001). Conclusion: Tofacitinib demonstrated a significant improvement in psoriasis disease severity and symptoms with 12 weeks' therapy.

Fractional Erbium YAG Laser Resurfacing Versus 20% Trichloroacetic Acid Chemical Peeling in the Treatment of Acne Scars: A Comparative Study.

Background: Acne scarring not only affects the aesthetic appearance of an individual but also has a detrimental effect on mental health and social life. Various treatment modalities are available for acne scars. Aim: In this study, fractional erbium-doped yttrium-aluminum-garnet (Er:YAG) laser resurfacing was compared with 20% trichloroacetic acid (TCA) peeling in terms of efficacy and safety. Materials and Methods: This prospective comparative study included 50 subjects of acne scar who were randomly divided into Groups A and B, 25 patients in each group. Group A was treated with 4 sessions of fractional Er:YAG laser and Group B with 4 session of 20% TCA application as chemical peeling, repeated every 21 days over a period of 3 months. The patients were evaluated for improvement at each visit using Goodman and Baron's qualitative and quantitative acne scar grading. Results: Statistically significant improvement in Goodman and Barron's qualitative acne scar grades was observed in both groups. At the end of therapy, that is, after 12 weeks of therapy, the mean percentage reduction in Goodman and Baron's quantitative acne scar scores was 21.69% ± 16% in Group A and 20.97% ± 8.70% in Group B. In regards of complications, both procedures were well tolerated. Conclusion: We concluded that fractional Er:YAG laser resurfacing and 20% TCA peel application in the treatment of atrophic acne scar are equally efficacious. Both procedures are safe and well tolerated by the patients.

A Case Series of Mucocutaneous Mucormycosis and its Risk Factors among SARS-CoV-2 Patients.

Mucormycosis is a rare, aggressive angioinvasive deep fungal infection caused by mucorales. The epidemiology of mucormycosis has changed in recent times with the increase in incidence, identification of new causative agents, and predisposing factors. The clinical spectrum of mucormycosis includes rhinocerebral, sinopulmonary, cutaneous, and disseminated forms. Cutaneous mucormycosis is an emerging infectious disease especially in post COVID-19 era. Cutaneous mucormycosis can be of two varieties: primary cutaneous and secondary cutaneous. Primary cutaneous mucormycosis is caused by direct inoculation of spores at the site of local trauma resulting in necrotic ulcers, especially, in immunosuppressed patient. Secondary cutaneous mucormycosis results from either dissemination or local invasion to the skin from a rhinocerebral form. The existing data on mucocutaneous mucormycosis is sparse especially in India. Herein, we present a case series describing the demographic factors, predisposing factors, clinical presentation, management of unique cases of mucocutaneous mucormycosis and its association with COVID-19 infection.

An Intention-to-Treat-Analysis of the Efficacy of Immunotherapy Using Mycobacterium W Vaccine and Purified Protein Derivative of Tuberculin for Warts With Assessment of Improvement in Quality of Life.

Introduction: Lately, immunotherapy has evolved as a safe and reliable management option for treatment of warts. Various immunogens among others in use include vaccines and antigens like purified Protein Derivative of Tuberculin (PPD) and mycobacterium w (Mw) or mycobacterium indicum prani vaccines. Objectives: The study was aimed to assess the effectiveness and safety profile of intralesional Mw vaccine against intralesional PPD for the management of multiple warts with assessment of the improvement in quality of life (QoL) using the Dermatology Life Quality Index questionnaire. Methods: Patients aged above 12 years with ≥2 warts were recruited for the study. These individuals were randomized into groups A and B, namely Mw vaccine (group A) and PPD Tuberculin (group B). At each visit, 0.1-0.2 ml of active antigen was infiltrated intralesionally into the largest/mother wart. The injections were repeated after every 4 weeks, for the next 12 weeks. QoL improvement was measured. Results: This intention to treat analysis was completed by 102 patients, of which 55 were in group A and 47 in group B. The rate of complete clearance was comparable in group A (76.3%) with the one in group B (65.9%, P = 0.064). Prior to treatment initiation, the most severely impacted domain of life by warts was 'symptoms and feelings'. There was a statistically significant improvement in QoL at the end of the treatment ( P <0.01). Conclusion: Mw vaccine holds leverage over PPD with a marginally higher rate of clearance and less adverse events for managing warts.

An Observational Study of Mucocutaneous Manifestations among SARS-CoV-2 Patients from Three COVID-19 Dedicated Tertiary Care Centers.

INTRODUCTION: Ever since the outbreak of COVID-19, the respiratory system has been the chief focus of researches, however, understanding the impact of this disease on the integumentary system is just as essential. OBJECTIVES: We aimed at collecting data on any cutaneous manifestation arising in patients with active and recovering COVID-19 infection, or a direct consequence of the infection's treatment, and correlating these findings with systemic disease severity and duration. MATERIALS AND METHODS: A prospective observational study was conducted in three tertiary care centers from Rajasthan, India, to acquire data of laboratory-confirmed cases of COVID-19 presenting with any mucocutaneous manifestation. RESULTS: Eight predominant patterns of dermatological involvement were seen, namely, maculopapular (14.59%), urticarial (13.17%), perniotic (12.1%), pityriasis rosea (11.74%), acral erythema/edema (10.3%), petechial (4.63%), vesicular (2.49%), and livedo (1.78%). Rare findings included eruptive pseudoangioma, eruptive hypomelanosis, alopecia parvimaculata, geographic tongue, chikungunya-like hyperpigmentation, and nail changes. On correlating these findings with the gradient of the disease, livedo, vasculitis, exfoliation, and erythroderma were associated with severe disease, whereas perniosis and eruptive pseudoangioma were seen in mild illness. CONCLUSION: We reported a few previously unpublished skin manifestations of COVID-19, namely, geographic tongue, chikungunya-like pigmentation, eruptive hypomelanosis, and alopecia parvimaculata. This study provides a visual description of the muco-cutaneous manifestations of COVID-19 disease which could aid a dermatologist or physician in early diagnosis of this novel infection, especially in a resource-poor setting.
