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.

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 and Safety of Erbium-YAG Laser Ablation Therapy in Superficial Dermatoses: The Workhorse of Dermatology.

Background: Erbium-YAG laser has been the working horse in dermatology for years. Surprisingly, data on the efficacy and adverse effects of this novel resurfacing and ablative technique of erbium-YAG laser for superficial dermatoses in Indian skin is limited. Aim and Objective: To evaluate the efficacy and safety profile of erbium-YAG laser ablation in superficial cutaneous lesions. Materials and Methods: Two hundred and fifty patients of various superficial dermatoses, treatable by erbium-YAG laser, were recruited in the study. All the patients were subjected to erbium-YAG laser sessions. The number of laser sessions, fluence, frequency and other parameters were individualized as per the respective dermatosis. The clinical response was evaluated as grade 4 (100% lesion clearance), grade 3 (75-99%), grade 2 (50-75%) or grade 1 (<50%). Results: The overall mean age of our study group was 37.70 years. In our study, 52.38% cases of verruca plana, 36.84% cases of seborrheic keratosis, 56.4% cases of xanthelasma palpebrarum, 22% cases of acquired melanocytic nevus, 23.8% cases of plantar wart and 40% cases of sebaceous hyperplasia showed complete clearance. The most common adverse effect was post-laser erythema in 50.4% of cases, followed by pain in 36.8%. Besides this, scarring and dyspigmentation were observed in 11.6% and 12% of cases, respectively. The rate of recurrence on 3 months follow-up was 9 (23.07%) cases in xanthelasma palpebrarum, 11 (28.9%) cases in seborrheic keratosis, 10 (23.8%) cases in verruca plana and 9 (42.8%) cases in plantar warts. Conclusion: This study suggested that erbium-YAG ablation achieved good results for superficial lesions like verruca plana, seborrheic keratosis, xanthelasma palpebrarum, plantar wart, sebaceous hyperplasia and acquired melanocytic nevus. Thus, Er: YAG laser can offer a one-step procedure with better cosmetic results and a lesser rate of recurrence.

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.

Intralesional Purified Protein Derivative of Tuberculin Versus Intralesional Mycobacterium W Vaccine in Treatment of Recalcitrant Extragenital Warts: A Randomized, Single-Blinded, Comparative Study.

Introduction: Of late, immunotherapy has emerged as a promising therapeutic modality for the treatment of recalcitrant and difficult to treat warts. Purified protein derivative of tuberculin (PDD) and mycobacterium w (Mw) vaccine hold promising prospects for the treatment of verruca, especially in a country like ours where a majority of the population is already sensitized to mycobacterium tuberculosis both due to disease endemicity and Bacillus Calmette-Guérin (BCG) vaccination. Aims and Objectives: We aimed at evaluating the treatment outcome of intralesional PPD tuberculin and Mw vaccine in the treatment of recalcitrant extragenital warts in immunocompetent subjects. Materials and Methods: The patients included immunocompetent subjects between the ages of 16 and 65 years with two or more extragenital warts. The patients were randomized into two groups, namely A (PPD Tuberculin) and B (Mw vaccine). In both groups, 0.1 mL of active intralesional immunogen was injected at the base of the largest wart. The doses were repeated at 4 weeks' intervals for a maximum of 5 injections. Additionally, the improvement in quality of life was measured using the Hindi-validated version of the Dermatology Quality of Life Index (DLQI) questionnaire. Results: Ninety-seven patients completed the study, with 46 in group A and 51 in group B. In group A, 24 (52.17%) patients had complete clearance in all warts, and in group B, 32 (62.75%) (P = 0.38). The most common adverse event in patients of group A was transient injection site erythema and swelling, whereas that in group B was mild transient fever. None of the patients showed any signs of recurrence in the ensuing follow-up period. There was a statistically significant improvement in the mean DLQI scores after treatment in both groups (P < 0.0001). Conclusion: Both PPD Tuberculin and Mw vaccine are effective in the treatment of recalcitrant warts with minimal recurrence rate. The safety profile of PPD is superior to Mw vaccine. We suggest both to be used as first-line therapy in the treatment of difficult to treat warts.

Evaluation of the Knowledge, Attitude and Practice of Patients on Immunosuppressive Drugs Towards COVID-19 Attending Dermatology Department- A Multicentric Cross-Section Study.

BACKGROUND: The deadly COVID-19 (Coronavirus Disease 2019) or SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) was identified for the first time in December 2019 from Wuhan, China, and by the beginning of March 2020, it was declared a pandemic by the World Health Organization (WHO). Despite so many government regulations and awareness measures, there is still a lacuna between the gravity of illness and the knowledge of the average person toward it. OBJECTIVE: We aimed at assessing the knowledge, attitude, and behavioral practice (KAP) of patients on immunosuppressive medication attending the dermatology department toward, COVID-19. MATERIAL AND METHODS: A self-designed printed/digital questionnaire consisting of 30 questions (Hindi and English) was supplied to patients being treated with any systemic immunosuppressives (for at least 3 weeks), for any dermatological ailment. The questionnaire consisted of 12 questions assessing the knowledge, 11 for attitude, and 7 for practices of patients toward COVID-19. RESULTS: The study included 237 patients with a mean age of 44.57 ± 13.72 years. The correct knowledge toward COVID-19 was present in 126 (53.16%) patients with a mean score of 7.79 ± 3.08 out of 13. The mean attitude score was 8.35 ± 2.16 (out of 11) while the mean score of practice was 5.64 ± 2.03 (out of 8). Increased hygiene levels were seen in 220 (92.83%) patients. Sixty-six (27.85%) patients admitted to stopping their prescribed immunosuppressives by themselves during COVID-19 and a significant proportion agreed to the use of alternative medicines with questionable efficacy (n = 91; 38.39%). A significant difference in KAP was found across various strata of society like gender, age, socioeconomic status, literacy, and residence (P < 0.001). LIMITATIONS: Our study was limited by small sample size, absence of a control group with healthy individuals, and short duration of the study. CONCLUSIONS: Most of the participants had poor knowledge, a positive attitude, and good practices toward COVID-19. Proper counseling of patients and the use of telemedicine could help combat the gap in KAP without compromising the healthcare facilities needed for the management of such patients.

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.
