Three-part scoring system (tripartite) for teledermatology versus International Contact Dermatitis Research Group criteria to interpret patch test readings: A comparative, observational study.

Background The International Contact Dermatitis Research Group (ICDRG) grading is the gold standard and is used to interpret patch test results in allergic contact dermatitis (ACD). The ICDRG readings include a combination of visual and palpation findings. Digital photography limits palpation. An alternative scoring system exists to analyse 2D images and interpret patch test readings in teledermatology (TD). Aims To compare tri-partite scoring system (TPSS) (TD) with ICDRG (face-to-face) and to assess the feasibility of TPSS by TD. Methods In this observational study, two investigators each scored the patch test readings for 78 patients at the 48th h, 96th h and on the 7th day. Results The TPSS has a sensitivity of 100%, specificity of 93.34%, positive predictive value of 91.67% and negative predictive value of 100%. At a confidence interval of 95%, Cohen's kappa (0.90) indicated excellent agreement between both investigators. The concordance between both scoring systems was at 93.2% for agreement and 6.82% for disagreement. Polysensitisation (6 patients with 16 allergens) was detected equally in both methods. Limitations A single centre study. Conclusion The readings obtained by TPSS were in agreement with ICDRG. TPSS can reduce the number of patient visits by 50% and may be used during COVID-19 times and beyond.

Dermatoscopic evaluation of leprosy: A multi-centre cross-sectional study.

Background Leprosy is known to be a great mimicker. Its dermatoscopic evaluation may be of value in establishing diagnosis. Objective To study the dermatoscopic findings encountered across the leprosy spectrum. Methods This was a multi-centre cross-sectional study of leprosy patients, where after a thorough cutaneous and neurological evaluation, representative skin lesions from the study patients were photographed in standard settings, and the most representative skin lesions were chosen for dermatoscopic evaluation. Data was entered in a structured proforma and a descriptive analysis of dermatoscopic patterns was carried out. Results A total of 53 cases of ages between 14 and 80 years, ranging from tuberculoid to the lepromatous spectrum of disease, with active skin lesions in the form of patches and plaques were included. The spectrum of leprosy as per Ridley-Jopling classification at diagnosis was indeterminate in 1 (1.9%), tuberculoid in 1 (1.9%), borderline tuberculoid in 25 (21.5%), borderline lepromatous in 9 (17%), lepromatous in 14 (26.4%) and histoid in 3 (5.7%). Dermatoscopic features included distorted pigment network in 48 (90.6%), focal white areas in 40 (75.5%), reduced eccrine and follicular openings in 43 (81.1%), widened skin lines in 28 (52.8%), circle hairs in 15 (28.3%) and white shiny streaks in 17 (32.1%). Conclusion Dermatoscopy is a practical, non-invasive device to assess skin lesions of leprosy and provide cues to its diagnosis, spectral classification and differentiating it from other granulomatous disorders. However, dermatoscopy alone cannot reliably differentiate between the various types of leprosy and future large-scale studies are required. Limitations of the study The numbers for each subtype were variable and few in some spectrum of leprosy patients. A dermatoscopic-histologic correlation was not done.

Non-venereal genital dermatoses and their impact on quality of life-A cross-sectional study.

BACKGROUND: Lesions on the external genitalia could be venereal or non-venereal. Non-venereal genital dermatoses are common and may cause considerable anxiety to patients, particularly if noticed after sexual intercourse. However, this aspect has not been studied much till now. OBJECTIVES: Our study proposes to describe the profile of non-venereal genital dermatoses and determine their impact on quality of life both social and sexual, using the dermatology life quality index questionnaire. METHODS: We recruited patients aged 18 years and above, who were diagnosed to have non-venereal genital dermatoses during the study period. A detailed history was obtained and clinical examination done with relevant investigations when necessary. The dermatology life quality index was assessed and graded in all patients using Finlay dermatology life quality index questionnaire. RESULTS: A total of 293 patients with non-venereal genital dermatoses were seen and 25 different dermatoses were observed. Men 242(82.6%) outnumbered women. The commonest age group affected was 31-50 years 144(50%). Chronic inflammatory dermatoses 135(41.6%) constituted the majority of cases. Scrotal dermatitis 46(15.7%), lichen simplex chronicus 37(12.6%), vitiligo 31(10.6%) were seen most frequently. In the study group, 111(37.9%) patients had moderate and 133(45.4%) had large impact on the quality of life. Erectile dysfunction was seen in 48(19.8%) men and 9(3.7%) had premature ejaculation. A significant effect on dermatology life quality index was found with increasing age (P = 0.007), positive marital status (P = 0.006), history of unprotected sex (P < 0.001), history of recurrences (P = 0.002) and venereophobia. (P = 0.008). LIMITATIONS: The number of women in the study group was less compared to men and we could not ascertain the type of sexual dysfunction in them. CONCLUSION: Non-venereal genital dermatoses are common, more so among men. They have a significant impact on the quality of life of the individual. Recognizing and addressing this problem will help in managing these patients effectively.

Updates on Management of Leprosy in the Context of COVID-19 Pandemic: Recommendations by IADVL SIG Leprosy.

The Special Interest Group (SIG) on leprosy thought it to be prudent to revisit its previous practice recommendations through this update. During this period, the pandemic course shifted to a 'second wave' riding on the 'delta variant'. While the number of cases increased manifold, so did the research on all aspects of the disease. Introduction of vaccination and data from various drug trials have an impact on current best practices on management of diseases including leprosy. The beneficial results of using steroids in management of COVID-19, gives elbow room regarding its usage in conditions like lepra reactions. On the other hand, the increase in cases of Mucormycosis again underlines applying due caution while recommending immunosuppressants to a patient already suffering from COVID-19. This recommendation update from SIG leprosy reflects current understanding about managing leprosy while the dynamic pandemic continues with its ebbs and flows.

Study of mucocutaneous manifestations of HIV and its relation to total lymphocyte count.

INTRODUCTION: HIV is associated with various mucocutaneous manifestations which may be the first pointers toward HIV and can also be prognostic markers for disease progression. This study was done to note the different mucocutaneous lesions present in HIV and their relation to total lymphocyte count (TLC). METHODOLOGY: Three hundred and seventy-nine HIV patients attending the Department of Dermatology, Venereology, and Leprosy were included in the study. They were screened for the presence of any mucocutaneous lesions. TLC in patients presenting with mucocutaneous lesions was done and also CD4 count was done wherever possible. RESULTS: Among 379 patients, 53.8% developed mucocutaneous manifestations. Male: female ratio was 2.2:1. Majority of patients belonged to 20-39 years age group. Among mucocutaneous manifestations, oral candidiasis was the most common, followed by herpes zoster and dermatophytoses. Adverse drug reactions were noted in few. The majority of patients had TLC <1500/mm3 and CD4 <200. CONCLUSION: Mucocutaneous manifestations are common and have varied presentation in HIV/AIDS. Patients with mucocutaneous manifestations were clustered at lower TLC and CD4 count. Like CD4 count, TLC can be considered as a marker for disease progression.

Lichen Planus and Metabolic Syndrome: Is There a Relation?

BACKGROUND: Recent data suggests association of lichen planus (LP) with various systemic disorders. Relationship between LP and metabolic syndrome (MS) is not yet taken into account. MS has been associated with increased risk of cardiovascular diseases. Hence, earlier detection and treatment could potentially decrease mortality and improve the quality of life in these patients. OBJECTIVES: To find out the association of LP with MS. MATERIALS AND METHODS: About 100 LP patients and 50 healthy adults were investigated for fasting blood glucose (FBS) and lipid profile. MS was diagnosed as per National Cholesterol Education Program's Adult Treatment Panel III guidelines. RESULTS: Serum cholesterol, triglycerides, low density lipoprotein (LDL-C), and very low density lipoprotein (VLDL-C) values were significantly increased in cases as compared to controls (P < 0.05 in all). About 42% of patients showed raised FBS level as compared to 10% controls (P = 0.0003). MS was more prevalent in cases than in controls (43% versus 26% respectively, P = 0.045). Odds ratio was highest in FBS and waist circumference. LIMITATIONS: As the cases and controls are included from a local area, the result may differ from other parts of the world. CONCLUSION: Diabetes mellitus, dyslipidemia, and MS are seen more commonly in LP patients.

Role of tetracycline in recalcitrant erythema nodosum.

Erythema nodosum is a type of septal panniculitis. We report a case of 40 year old male of chronic and recalcitrant erythema nodosum who responded to tetracycline. The possible mechanism of action of tetracycline is analyzed. Tetracycline should be considered as a logical option in recalcitrant erythema nodosum.
