Efficacy of 15% trichloroacetic acid peel versus 35% glycolic acid peel in acanthosis Nigricans: A randomized open-label study.

Introduction: Acanthosis Nigricans (AN) is an acquired disorder of keratinization. It presents as hyperpigmentation, velvety texture of skin that can involve any part of the body including the face. Different topical, systemic therapies, or physical therapies including laser have been explored. However, there are not many randomized controlled studies for the majority of therapy alternatives besides lifestyle modifications and weight reduction. Objectives: The aim of this study was to compare the effectiveness of 15% trichloroacetic acid (TCA) and 35% glycolic acid (GA) peel for AN. Materials and Methods: Forty participants were included and randomized into two groups. In groups A and B, peeling with 15% TCA and 35% GA was done, respectively. The effectiveness of each peel was assessed using changes in the Acanthosis Nigricans Area and Severity Index Score (ANASI) and Physician Assessment Score. Statistical analysis included Wilcoxon-Mann-Whitney test, Friedman test, and generalized estimating equations. Results: The overall change in ANASI over time was compared in the two groups using the generalized estimating equations method. A significant difference was observed in the trend of ANASI over time between the two groups (P < 0.001). TCA peel group showed more change in ANASI as compared with GA peel group. Conclusion: In our research, 15% TCA has a better efficacy when compared with 35% GA peel after three sessions of chemical peeling. We therefore recommend the use of 15% TCA peel in AN as a safe and effective treatment option. However, more comprehensive randomized control studies are required for supporting data.

Assessment of Cardiovascular Risk Factors in Women Having Female Pattern Hair Loss.

Background: Many studies have associated male androgenetic alopecia with the risk of cardiovascular disorders but very few studies have addressed this association in women with FPHL. Materials and Methods: This was a cross-sectional hospital-based study in which a total of 50 women (18-45 years) were recruited. The objective was to measure carotid intima-media thickness (CIMT) by doppler ultrasound, Body mass index (BMI), waist circumference, lipid profile, fasting blood sugar (FBS), insulin, testosterone, Sex hormone binding globulin (SHBG), hs-CRP, ESR and fibrinogen, in pre-menopausal women having FPHL and to correlate these parameters with severity of FPHL. The prevalence of Metabolic syndrome (MetS) and Insulin resistance were evaluated. Results: Metabolic syndrome and insulin resistance were found in 12 (24%) and 17 (34%) cases respectively. Hypercholesterolemia, elevated LDL levels and hypertriglyceridemia, low HDL levels and hyperinsulinemia were found in 11 (22%), 31 (62%), 9 (18%), 17 (34%) and 7 (14%) cases respectively. 8 (16%) cases were diabetics. Elevated ESR, increased fibrinogen levels and elevated hs-CRP were found in 43 (86%), 10 (20%) and 21 (42%) cases respectively. CIMT was found to be within its normal range. Correlation of CIMT, anthropometric indices (BMI and WC), biochemical markers (serum cholesterol, triglycerides, FBS, and fibrinogen), and presence of metabolic syndrome with severity of FPHL in terms of Ludwig grade was found to be statistically significant. Conclusions: The determination of metabolic syndrome, insulin resistance and acute phase reactants such as hs-CRP and fibrinogen may be useful screening methods to detect increased cardiovascular risk in women with FPHL.

Lymphomatoid Papulosis: A Case Report.

Lymphomatoid papulosis (LYP) is a chronic CD 30 + lymphoproliferative disorder (LPD) which is characterized by chronic, recurrent, and self-healing papulonecrotic or papulonodular skin eruptions, which are clinically benign and histopathologically malignant. It can resolve spontaneously; however, long-term follow-up is essential as it can progress to malignant lymphoma in 10-20% of the patients. We hereby report a case of a 42-year-old male presenting with recurrent papulonecrotic lesions over the face, trunk, and extremities from the last 3 years which heal with post-inflammatory hyperpigmentation and atrophic scars with a history of treated pulmonary tuberculosis one year back. There was no systemic involvement. LYP, involving cosmetically sensitive area like face, is an infrequent finding.

Is Atopic Dermatitis a Risk Factor for Thyroid Autoimmunity? - A Cross-Sectional Study from a Tertiary Care Center in India.

Background: Because of the counter-regulation of Th1 and Th2 cells, Th1-type autoimmune diseases like thyroid autoimmunity and Th2-mediated allergic diseases like atopic dermatitis (AD) should occur in mutually exclusive populations. However, thyroid autoimmunity has been associated with chronic urticaria, and atopy is considered a cause of both AD and urticaria. Objectives: To assess the frequency of thyroid autoimmunity in children with AD and to study the correlation between the clinical severity of AD using the SCORing Atopic Dermatitis (SCORAD) score, and biochemical parameters of serum immunoglobulin E (IgE), absolute eosinophil count, and vitamin D levels. Materials and Methods: A hospital-based cross-sectional study was conducted, recruiting children (0-18 years) with AD. Patients on drugs affecting thyroid dysfunction and those with sick euthyroid syndrome or an immunodeficiency disorder were excluded. Clinical severity was assessed using SCORAD, and the thyroid profile, anti-thyroid peroxidase antibodies, antinuclear antibody (ANA), absolute eosinophil count, serum IgE, and vitamin D levels were measured. Results: Thyroid autoimmunity was diagnosed in 18.9% (10/53) of children. There was a significant correlation between SCORAD and serum IgE (r = 0.432, P = 0.002) and absolute eosinophil count (r = 0.575, P = <0.001). There was a negative correlation between SCORAD and vitamin D levels (r = -0.373, P = 0.006). Conclusions: Thyroid autoimmunity may be associated with AD, and a high index of suspicion is essential. Vitamin D also should be supplemented in children with AD as it is frequently found to be low, especially in severe cases. Multi-center case-control studies are required to determine the prevalence of thyroid autoimmunity in children with AD.

Comorbidities in Paediatric Psoriasis: Experience from a Tertiary Care Centre.

Background: Psoriasis begins in childhood in around one-third of the cases. There has been conflicting evidence regarding the association of paediatric psoriasis with comorbidities. Aims and Objectives: The objective of this study was to find out various comorbidities (abnormal body mass index, metabolic syndrome, lipid abnormalities, diabetes mellitus, and raised blood glucose) associated with paediatric psoriasis. Materials and Methods: All patients of psoriasis (age <18 years) who visited the Paediatric Psoriasis clinic from January 2017 to September 2021 were recruited in this record-based study. Results: Records of 100 patients were analysed, with female to male ratio of 1:1. The age group ranged from 11 months to 18 years. The average body surface area involved was 5.43%. The average psoriasis area and severity index was 2.47. Joint involvement was seen in 7% of patients in our study. A total of 52 (52%) patients had abnormal body mass index, out of which 21 patients were overweight and 31 were obese. At least one lipid abnormality was found in 66 (66%) patients. The most common lipid abnormality was decreased high-density lipoprotein, followed by raised total cholesterol, raised total triglycerides and raised low-density lipoprotein. 8 (8%) patients were found to have raised blood glucose levels. Out of which, six had impaired fasting glucose and two were diagnosed with diabetes mellitus. 5 (5%) patients were diagnosed with metabolic syndrome. Conclusion: Paediatric psoriasis is a chronic disfiguring disease and may have profound emotional and psychological effects. There is a lack of studies from India on the prevalence of these comorbidities in paediatric psoriasis. More studies are required from different parts of the world for a better understanding of paediatric psoriasis.

Interleukin Levels and Non-Alcoholic Fatty Liver Disease in Chronic Plaque Psoriasis: An Analytical Case Control Study.

Background: Psoriasis is a chronic, immune mediated inflammatory condition of the skin and imbalance in inflammatory mediators could result in insulin resistance, metabolic syndrome and facilitate the occurrence and progression of Non-alcoholic fatty liver disease (NAFLD). Objectives: Primary objectives: To study the frequency of NAFLD in cases of chronic plaque psoriasis and controlsTo study the interleukin levels in cases of chronic plaque psoriasis and controls. Secondary objectives: To study the BMI, lipid profile, waist circumference, FBS (fasting blood sugar), PPBS (post prandial blood sugar) and serum insulin in cases and controlsTo study the association of age, duration of psoriasis, PASI (psoriasis area severity index), BSA (body surface area) involved, BMI (body mass index), lipid profile, obesity, waist circumference, FBS (fasting blood sugar), PPBS (post prandial blood sugar) and serum insulin levels with NAFLD in patients of chronic plaque psoriasisTo correlate serum levels of IL1-ß, IL6 and TNF-α with NAFLD in patients of chronic plaque psoriasis. Methods: 50 clinically diagnosed cases of chronic plaque psoriasis with age ≥ 18years, diseases duration ≥ 6 months and 30 age and sex matched controls were recruited. PASI, BSA of cases was calculated and BMI, BP, WC of all subjects was measured. Serum lipid profile, FBS, PPBS, insulin level, IL1- ß , IL6, TNF- α , high frequency B-mode ultrasound, LFT and fibroscan were done in all subjects. Results: 28(56.0%) cases and 2(6.6%) controls had NAFLD with statistically significant difference. Significantly elevated WC, serum insulin, deranged lipid profile, fatty liver, transaminitis, fibroscan score, liver fibrosis, NAFLD and interleukins were found in cases vs controls. There was a significant association of NAFLD in psoriatic patients with increasing duration of psoriasis, BMI ≥23 Kg/m2, high WC, increasing BSA involved, deranged lipid profile, raised total cholesterol levels and increasing number of risk factors. Nonsignificant but positive association of NAFLD in cases was found with high levels of IL1 - ß, IL - 6, TNF-α, FBS and increasing PASI. Conclusion: Significantly increased interleukin levels and their weak positive correlation with the severity of psoriasis (PASI, BSA) in patients of chronic plaque psoriasis explains the possible role of inflammation in the causation of psoriasis. Screening may be considered in psoriatic patients with increasing duration of psoriasis, high WC, high BSA involved, high BMI, obesity, dyslipidemia and insulin resistance. Limitations: Small sample size. Conflict of Intrest: NONE.

Comparative Efficacy of Topical Finasteride (0.25%) in Combination with Minoxidil (5%) Against 5% Minoxidil or 0.25% Finasteride Alone in Male Androgenetic Alopecia: A Pilot, Randomized Open-Label Study.

Background: Androgenetic alopecia (AGA) is the most common cause of hair loss in males which remains a therapeutic challenge. Objectives: To compare the efficacy of topical 5% minoxidil and 0.25% finasteride combination (MNF) over 5% minoxidil (MNX) or 0.25% finasteride (FNS) alone by assessing hair count, physician assessment score (PAS), and patient satisfaction score (PSS). Materials and Methods: Pilot randomized open-label study where 60 male patients with AGA ≥ III grade were randomized into three treatment groups and evaluated over 24 weeks. Improvement in hair count was assessed manually using dermoscopy. Global photographs were used to assess PAS. Side effects were evaluated using relevant laboratory investigations. Results: At the 12th and 24th week, all three groups showed significant improvement in total hair density as compared to baseline (P < 0.001). None of the groups was superior to the other (P > 0.05) at the 12th week but at 24th week, MNF was comparatively superior (P < 0.02). At the 12th week and 24th week, all three groups showed significant improvement in terminal hair density as compared to baseline (P < 0.001). In the 12th week, MNF was comparatively superior (P = 0.028) and at the 24th week, MNF was comparatively superior (P < 0.02). PAS and PSS were significantly better with MNF and MNX compared to FNS (P < 0.004). Side effects such as scaling and itching were reported with MNF and MNX. Conclusion: Topical minoxidil 5% and finasteride 0.25% had an overall better efficacy compared to monotherapy without significant side effects.

Granulomatous Vulvitis: A Rare Case of Chronic Inflammatory Hypertrophy of Vulvar Labia Related to Ulcerative Colitis.

Granulomatous vulvitis (GV) is an idiopathic entity typically presenting with chronic, painless swelling of the genitals with histologic evidence of granulomatous inflammation. Granulomatous vulvitis can typically start as an acute inflammatory condition, which gradually transforms into a chronic disease with a relapsing and remitting course leading to swollen, indurated, and distorted external genitalia. Association of GV with Crohn's disease is being increasingly recognized. However, the association of GV with ulcerative colitis is unreported. Here, we report a rare case of GV in a middle-aged Indian female with characteristic gastrointestinal involvement suggestive of ulcerative colitis. We hope to contribute to an earlier recognition and a better management of the vulvar and gastrointestinal lesions of ulcerative colitis.

Clinical and epidemiological profile of lichen striatus in children-Experience from a tertiary care hospital.

We analyzed records of 30 patients with lichen striatus (age < 18 years) in this retrospective study. Seventy percent were females and 30% were males with a mean age of diagnosis of 5.38 ± 4.22 years. The most common age group affected was 0-4 years. The mean duration of lichen striatus was 6.66 ± 4.22 months. Atopy was present in 9 (30%) patients. Although LS is a benign self-limited dermatosis, long-term prospective studies with a greater number of patients will help in better understanding of the disease including its etiopathogenesis and association with atopy.

Comparative Efficacy of Topical Minoxidil Alone Against Combination of Topical Minoxidil and Platelet Rich Plasma in Women with Female Pattern Hair Loss-A Pilot, Open Randomised Trial.

Background: Female pattern hair loss (FPHL) affects a significant proportion of population and poses a major therapeutic challenge. Aims and Objectives: To compare the efficacy and safety profile of combination of topical minoxidil 2% plus platelet rich plasma (PRP) (group 1) and topical minoxidil 2% solution alone (group 2) in women having FPHL. Materials and Methods: 26 females with FPHL were randomised into two treatment groups. They were evaluated for increase in hair density, reduction in hair pull test (HPT), patient satisfaction score (PSS) and side effects. Results: Mean change of 34.92 ± 8.39 hairs/cm2 in group 1 (P < 0.001) and 31.21 ± 8.30 hair/cm2 in group 2 (P < 0.001) was seen. 16.7% and 28.6% patients in Group 1 and 2, respectively, had PSS of highly satisfied. The reduction in HPT was significant with P = 0.0123 (group 1) and P = 0.0128 (group 2). There was no statistically significant difference between the two groups. No major side effects were reported. Conclusion: Minoxidil-PRP combination therapy is an effective modality for FPHL but is not superior to topical 2% minoxidil therapy alone. PRP is a promising option in patients with minoxidil related compliance issues.

Clinical and Metabolic Characteristics in Hidradenitis Suppurativa - An Indian Perspective.

Background: Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent follicular disorder affecting apocrine gland bearing areas such as axillae, inframammary area and groin. Significant association of HS with metabolic derangements such as hypertension, obesity, hyperlipidemia and hyperinsulinemia has been found. There is dearth of literature on epidemiological and metabolic profile of HS in Indian subjects. Aim: The aim of this study is to assess abnormalities in the levels of fasting blood glucose, serum insulin, and lipid profile in patients with HS. Primary Objective: To assess the frequency of abnormal levels of fasting blood sugar, serum insulin and lipid profile in patients with HS. Secondary objectives: To assess the frequency of hypertension, raised basal metabolic index, polycystic ovarian syndrome, follicular disorder, erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) in patients with HS and to assess the severity of of clinical presentation HS using Hurley staging system. Methodology: This is a retrospective record based study. Records of clinically diagnosed patients of HS, aged > 18 years fulfilling the inclusion and exclusion criteria were analysed. Results: Total 30 patients were recruited with 1:1 male to female ratio. Five (16.67%) cases fulfilled NCEP ATP III criteria for the diagnosis of metabolic syndrome. Statistically significant association was observed between severity of HS, in younger age group (<20 years), moderate to severe BMI, fasting serum insulin, fasting total cholesterol and raised ESR. Limitations: This is retrospective, hospital record based study with small sample size. Conclusion: Holistic management of HS should be individualized according to need of patient and it should be combined approach including dermatologist, plastic surgeon, psychiatrist and dietician. We recommend an initial screening for derangements in metabolic profile in these patients for more effective management and preventing long term cardiovascular complications.

Ulceration by Nocardia Otitidiscaviarum: A case study.

Nocardiosis is an acute, subacute or chronic infectious disease that occurs in cutaneous, pulmonary and disseminated forms. We present a case of Nocardiosis in a post-COVID-19 patient with cutaneous ulceration due to Nocardia otitidiscaviarum, managed with cotrimoxazole and linezolid. Early diagnosis and management proved crucial in preventing dissemination of the organism and improving the patient's outcome.
