Objectives Our objective was to assess the histological changes in atrophic acne scars and determine the vertical depth of each scar type. Methods A total of 32 boxcar, 10 ice-pick, and 7 rolling scars were biopsied. Tissue samples were stained with haematoxylin and eosin, Verhoeff-van Gieson, and Masson's trichrome stains. Acne scars were identified based on morphological changes in collagen and elastin, loss of pilosebaceous units in the scar area, and tilting of follicular units in the adjoining dermis. The depth of the scars was measured in µm. Results Atrophic acne scars revealed loose, haphazardly arranged collagen (71%) and reduced elastic tissue (96%). Appendageal tilting was noted in 44/49 (90%) biopsies, with consistent pilosebaceous unit loss in the scar. Mean depths of ice-pick, boxcar, and rolling scars were 1933.4 ± 1117.8 µm, 1327.88 ± 571.34 µm, and 1357.14 ± 578.3 µm, respectively. There was a significant difference in the mean depth of scars between ice-pick and boxcar scars (p=0.02). Additional findings noted were scar vascularisation (n=46), ectatic channels in the scar (n=18), mononuclear inflammatory infiltrates (n=43), calcinosis (n=3), demodex mites (n=2), solar elastosis (n=2), pigment-laden macrophages (n=2), granulomatous perifolliculitis (n=4), and pulled up eccrine glands (n=8). Based on existing data, the dose of fractional carbon dioxide (Fr: CO2) laser should be set to achieve an approximate depth of 1933.4 µm to address all atrophic scars. Limitations Small sample size and technical difficulties in histological sectioning of atrophic scar remain the main limitations of our study. Conclusion This study provides novel histological insights into facial atrophic acne scar characteristics and depth in skin of colour. Also, it gives data on the histological depth that needs to be achieved by energy devices, using the appropriate dose based published data.</p>","PeriodicalId":50376,"journal":{"name":"Indian Journal of Dermatology Venereology & Leprology","volume":" ","pages":"14-21"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144876577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are elevated in conditions like infections, malignancies, mental illness and drug reactions among others. Aim The study aimed at identifying the IMs that reflect the severity and recovery in severe cutaneous adverse drug reactions (SCARs). Methods A cross-sectional observational study was conducted among patients with SCARs (Stevens Johnson syndrome [SJS]/ toxic epidermal necrolysis [TEN] and drug reaction with eosinophilia and systemic symptoms [DRESS]) admitted to a tertiary care hospital over 18 months. Results Twenty SJS/TEN and 8 DRESS cases were included in the study. There were more females in the study (F: M = 2:1). Comparing the IMs of SJS/TEN and DRESS revealed that most markers on day 7 were lower as compared to day 0. There was a significant difference in eosinophil count (EC), procalcitonin (PCT) (p-value <0.05), and recovery time between the two groups. In the SJS/TEN group, markers like ferritin (>2000 ng/mL) and PCT (>2.0 ng/mL) were significantly higher, around the septic range, in patients with concurrent connective tissue disease and culture positivity. Ferritin (p-value- 0.025, rho- 0.578), PCT (p-value- 0.013, rho- 0.239), and ESR (p-value- 0.041, rho- 0.482) were associated with the severity of SJS/TEN. Patients with DRESS had an early recovery with a statistically significantly shorter hospital stay than SJS/TEN (p<0.005). Baseline severity-of-illness score for TEN levels, total counts, and day 7 PCT significantly reflected the time taken for recovery. Limitations Marker analysis was performed at baseline and on day 7 of admission, but not after complete clinical recovery, therefore indicating a trend but limited conclusive behaviour of markers at the time of recovery.

While multidrug therapy (MDT) has been effective, the emergence of antimicrobial resistance (AMR) to key drugs such as rifampicin, dapsone, and ofloxacin threatens leprosy control programs. Resistance mechanisms include mutations in genes such as rpoB (rifampicin), folP1 (dapsone), and gyrA (ofloxacin). Drug resistance contributes to treatment failures, prolonged transmission, and the emergence of severe complications, necessitating enhanced surveillance and diagnostic capabilities. Aims This study aimed to determine the rates of primary and secondary AMR in M. leprae among multi-bacillary leprosy patients attending a tertiary care institute in Uttarakhand. It also sought to identify patterns of genetic mutations associated with resistance. Methods This prospective, cross-sectional study was conducted from July 2022 to June 2024. Patients with a bacteriological index (BI) ≥2, fulfilling specific clinical criteria [treatment-naive, chronic or recurrent erythema nodosum leprosum (ENL), relapse or persistent positive morphological index (MI)] were recruited. Slit skin smears (SSS) were processed using polymerase chain reaction (PCR) -based gene amplification to detect mutations in rpoB, folP1 and gyrA. Amplified DNA samples were sequenced and analysed for resistance-associated mutations. Demographic and clinical data, including type of leprosy, BI, MI, and treatment history, were also collected. Results Out of 47 samples tested, 43 were successfully amplified. Resistance was detected in eight cases (17%). Primary resistance was noted in 4/20 treatment-naive patients (20%). Rifampicin resistance, attributed to the F439L mutation, was the most common (n = 4). Dapsone resistance due to P55L and P55S mutations was identified in two cases, while ofloxacin resistance associated with A91V and G89C mutations was seen in two cases. Limitations The study's findings are limited by its sample size and the focus on a single tertiary care centre, potentially restricting the generalisability of results. Additionally, not all samples were successfully amplified for analysis. Conclusion This study underscores the critical need for routine AMR testing in high-risk leprosy cases. Regional variations in resistance patterns necessitate localised surveillance to guide effective treatment strategies. Enhanced diagnostic capabilities, patient education, and policy-level interventions are essential to combat the rising threat of AMR in leprosy.</p>","PeriodicalId":50376,"journal":{"name":"Indian Journal of Dermatology Venereology & Leprology","volume":"92 1","pages":"37-42"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145949086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To formulate and validate a scoring system for IH based on dermoscopy - dermoscopy haemangioma assessment index (DHAI). To compare DHAI with the haemangioma activity score (HAS). Methods Consecutive patients with IH were taken for the study. At the time of presentation, each IH was clinically and by dermoscopy assessed by the first dermatologist. Clinical and dermoscopic images were taken and retrospectively analysed by a second and third dermatologist. The agreement between the three dermatologists was assessed using the inter-class correlation coefficient. Results The study included 45 patients with IH. Among the three observers, reliability analysis showed satisfactory results for DHAI with a Cronbach's alpha coefficient of 0.983, indicating good reliability and consistency. Inter-item correlation between all three observers was found to be positive and statistically significant (p-value <0.001). Thus, there was good agreement between the three dermatologists. On comparing with Haemangioma Activity Score (HAS), the correlation between HAS and DHAI was 0.703, which implies a high positive correlation. Limitations The primary limitation in our study was the very small number of patients. Secondly, the scoring system was not assessed longitudinally, so improvement in parameters with time could not be measured. Thirdly, the scoring system was not able to accurately measure the depth of IH. Conclusion DHAI is a good, reliable, and valid scoring system to assess the activity of IH, and can be used for future interventional studies on IH. DHAI can simplify the scoring of IH using a dermoscope and can provide more objective information as compared to the previous scoring system.</p>","PeriodicalId":50376,"journal":{"name":"Indian Journal of Dermatology Venereology & Leprology","volume":"92 1","pages":"31-36"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145948906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This integrative review used the electronic databases MEDLINE/PubMed and the Virtual Health Library (VHL), including 12 studies conducted predominantly in Brazil, China, India, and Ethiopia. We focused on the role of regulatory T (Treg) cells in Hansen's disease, specifically examining their frequency of expression and the functional characteristics of their subpopulations. Findings reveal the ubiquitous nature of Treg across clinical forms, particularly the CD3+CD4+CD25+FoxP3+ phenotype, with a pronounced frequency in multibacillary cases, including borderline-lepromatous and lepromatous leprosy. In these cases, a notable upregulation of inhibitory molecules (CTLA-4, PD-1) and the production of immunoregulatory cytokines (IL-10, TGF-β) are evident in skin lesions and/or in vitro-cultured cells. The intricate interplay of local stimuli, cytokine profiles, antigenic nature, receptor expressions, co-inhibitory molecules, and macrophage types modulates the cellular immune response, influencing disease severity.
