Background: The prevalence of skin diseases has increased over the last few decades, and they contribute to a significant burden on health-care systems across the world. Aims/Objective: This report looks at the burden of skin and subcutaneous diseases in terms of years lived with disability and agestandardised years lived with disability in India using the Global Burden of Disease Study results from 2017. Methods: Data were obtained from the Global Burden of Disease online interactive tool. Updated estimates of the world’s health for 359 diseases and injuries and 84 risk factors from 1990 to 2017 are available in this interactive tool. Results: Years lived with disability due to skin and subcutaneous diseases accounted for 4.02% of the total years lived with disability in India in 2017. There was an increase of 53.7% in all age standardised years lived with disability for all the skin and subcutaneous diseases from 1990 to 2017. Among skin and subcutaneous diseases, dermatitis contributed maximum years lived with disability (1.40 million; 95% uncertainty interval, 0.82–2.21) in 2017, followed by urticaria (1.02 million; 95% uncertainty interval, 0.06–1.44) with percentage increases of 48.9% and 45.7% respectively. Conclusion: The burden due to infectious skin diseases (e.g., scabies, fungal skin disease and bacterial skin disease) and non-infectious diseases (e.g., dermatitis, urticaria and psoriasis) has increased over the past three decades, however the age-standardised years lived with disability for leprosy, scabies, fungal infections, sexually transmitted infections and non-melanoma skin cancer (basal cell carcinoma) has decreased. The high burden of skin and subcutaneous diseases demand that they be given due importance in the national programmes and health policy of India.

Psoriasis, a prevalent chronic inflammatory skin disorder affecting 2– 3% of the global population, has transcended its dermatological confines, revealing a profound association with cardiovascular diseases (CVD). This comprehensive review explores the intricate interplay between psoriasis and cardiovascular system, delving into genetic links, immune pathways, and adipose tissue dysfunction beyond conventional CVD risk factors. The pathophysiological connections unveil unique signatures, distinct from other inflammatory skin conditions, in particular psoriasis-specific genetic polymorphisms in IL-23 and TNF-α have consistently been linked to CVD. The review navigates the complex landscape of psoriasis treatments, addressing challenges and future directions in particular relevance to CVDs in psoriasis. Therapeutic interventions, including TNF inhibitors (TNFi), present promise in reducing cardiovascular risks, and methotrexate could constitute a favourable choice. Conversely, the relationship between IL-12/23 inhibitors and cardiovascular risk remains uncertain, while recent evidence indicates that Janus kinase inhibitors may not carry CVD risks. Emerging evidence supports the safety and efficacy of IL-17 and IL-23 inhibitors in patients with CVDs, hinting at evolving therapeutic paradigms. Lifestyle modifications, statins, and emerging therapies offer preventive strategies. Dedicated screening guidelines for CVD risk assessment in psoriasis are however lacking. Further, the impact of different disease phenotypes and treatment hierarchies in cardiovascular outcomes remains elusive, demanding ongoing research at the intersection of dermatology, rheumatology, and cardiology. In conclusion, unraveling the intricate connections between psoriasis and CVD provides a foundation for a holistic approach to patient care. Collaboration between specialties, advancements in screening methodologies, and a nuanced understanding of treatment impacts are essential for comprehensive cardiovascular risk management in individuals with psoriasis. Plain Language Summary: Psoriasis is a skin condition that not only affects the skin but is also linked to issues in the body’s fat tissue, which can lead to inflammation and heart problems. The fat tissue in people with psoriasis contains various immune cells, contributing to obesity and insulin resistance. Research has found a strong connection between inflammation in fat tissues and cardiovascular problems in people with psoriasis. Specific substances released by fat tissue, like leptin, resistin, and adiponectin, can impact inflammation and cardiovascular health. Psoriasis patients often show increased levels of these substances. Treatment for psoriasis may influence cardiovascular health. Some studies suggest that certain medications, like methotrexate or TNF inhibitors, may lower the risk of heart events. However, there are also concerns about potential adverse effects, and further research is needed to fully understand how psoriasis treatments affect cardiovascular outcomes. To manage the cardiovascular risks associated with psoriasis, regular screening for heart-related issues is recommended. Lifestyle changes, such as a healthy diet, stress management, and smoking cessation, are also essential. Additionally, specific medications, like statins and metformin, may be beneficial in controlling cardiovascular risk factors in people with psoriasis. Despite advancements in understanding the relationship between psoriasis and cardiovascular health, there are still challenges. Research is ongoing to develop better screening guidelines and treatment strategies. Collaboration between dermatologists, rheumatologists, and cardiologists is crucial to address the complex nature of this condition and its impact on the heart.

A subset of multibacillary (MB) leprosy patients manifest with clinical “nonresponsiveness” to the fixed-duration, World Health Organization multidrug therapy MB regimen (WHO-MDT-MBR). The aim of this retrospective study was to assess the effectiveness and safety of alternate anti-leprosy therapy (ALT) in such patients. This is an analysis of patients’ records, registered in the leprosy clinic of our institute over a period of 6 years (2010–2015). The criteria for inadequate response/nonresponsiveness to treatment were as follows: 1) persistent/new lesions after completing ≥ 12 months of WHO-MDT-MBR (isolated reactions were ruled out histopathologically) and 2) persistent positive/increasing value of the morphological index (MI) and a 2 log increase in the bacteriological index (BI) after ≥ 12 months of WHO-MDT-MBR. Such cases were treated with ALT consisting of minocycline, clofazimine, and ofloxacin (24 months). Of 556 patients registered during the study period, 40.3% (224) were slit-skin smear (SSS) positive and 59.7% (332) were SSS negative. Of all, 35 patients (6.3%) satisfied the criteria for clinical nonresponsiveness. Of 224 SSS-positive patients, these 35 patients amounted to 15.6%. The mean BI and MI of these patients after completion of ≥ 12 months of WHO-MDT-MBR were 5.3 ± 0.6 and 14 ± 6.8%, respectively. After 6 months of treatment with ALT, MI became negative (0) in all these patients. After completion of ALT, the mean BI and MI became 1.7 ± 0.7 and 0%, respectively (P < 0.0001). There were 16 patients with corticosteroid-dependent recurrent/chronic erythema nodosum leprosum, who had excellent response with significant reduction in the number of reactional episodes and mean dose of prednisolone required (P < 0.0001). No serious adverse effects were noted. We conclude that ALT is safe and effective in the management of MB leprosy patients who are nonresponsive to 12 months of WHO-MDT-MBR.

Importance: Evidence is robust for the effectiveness of microneedle therapy in the management of postacne atrophic scarring. A home-based topical treatment with an efficacy comparable to microneedling would be a useful addition in the armamentarium of acne scar management. Objective: To compare the efficacy of topical tazarotene gel, 0.1%, with microneedling therapy in the management of moderate to severe atrophic acne scars. Design, Setting, and Participants: Prospective, observer-blinded, active-controlled, randomized clinical trial with 6 months of follow-up conducted between June 2, 2017, and February 28, 2018, at a tertiary care hospital in India. Thirty-six patients with grade 2 to 4 facial atrophic postacne scars and without a history of procedural treatment of acne scars within the previous year were recruited. Analyses were conducted using data from the evaluable population. Interventions: Both halves of each participant’s face were randomized to receive either microneedling or topical tazarotene therapy. Microneedling was conducted on 1 side of the face with a dermaroller having a needle length of 1.5 mm for a total of 4 sessions during the course of 3 months. Participants were instructed to apply topical tazarotene gel, 0.1%, to the other side of the face once every night during this same period. Main Outcomes and Measures: Patients were followed up at 3 and 6 months by a blinded observer, and improvements in acne scar severity based on Goodman and Baron quantitative and qualitative scores and a subjective independent dermatologist score (range, 0-10, with higher scores indicating better improvement) were assessed. Patient satisfaction was assessed using a patient global assessment score (ranging from 0 for no response to 10 for maximum improvement) at these follow-up visits. Results: There were 36 participants (13 men and 23 women; mean [range] age, 23.4 [18-30] years), and the median (interquartile range [IQR]) duration of acne was 6 (4-8) years. For the 34 participants included in the complete data analyses, the median (IQR) quantitative score for acne scar severity at the 6-month follow-up visit following treatment with either tazarotene (from a baseline of 8.0 [6.0-9.8] to 5.0 [3.0-6.0]) or microneedling (from a baseline of 7.0 [6.0-10.8] to 4.5 [3.0-6.0]) indicated significant improvement ( P < .001) that was comparable for both treatments (median [IQR] change in severity score from baseline, 2.5 [2.0-4.0] vs 3.0 [2.0-4.0]; P = .42). By contrast, median qualitative acne scar scores were the same for both treatment groups at baseline and did not significantly change following either treatment. Conclusions and Relevance: The present clinical trial showed comparable outcomes of both treatments for the overall improvement of quantitative facial acne scar severity. Level of Evidence: 1 .
