Background: Psoriasis is an inflammatory systemic disease with a chronic relapsing course. Methotrexate, a dihydrofolate reductase inhibitor, and Apremilast, an oral phosphodiesterase type 4 inhibitor, are currently the mainstay drugs in the treatment of psoriasis. Aims and Objectives: To compare the efficacy of Methotrexate with a combination of Methotrexate and Apremilast in treating chronic plaque psoriasis. Materials and Methods: The present study was a prospective comparative study conducted among 40 patients, aged above 18 years, with clinically diagnosed psoriasis attending Dermatology OPD of a tertiary care hospital in North India. The study utilised a pre-structured proforma to record a detailed demographic profile and clinical examination related to chronic plaque psoriasis. The patients were divided into two groups of 20 each. Group A was treated with oral Methotrexate, while Group B was treated with oral Apremilast and Methotrexate, and they were evaluated every 4 weeks for 12 weeks. Necessary investigations were done wherever indicated. Results: The male-to-female ratio was 1.35, and the majority (55.0%) of patients belonged to the age group of 31-50 years. 27.5% of patients had comorbidities like diabetes, hypertension, etc., The mean PASI score of group A at the first, second and third follow-ups was higher than that of group B. The reduction in mean PASI score was statistically significant in group B at successive follow-ups, with a percentage improvement of 89.4% at the end of 12 weeks. Conclusions: When comparing monotherapy with methotrexate and multidrug therapy with Methotrexate and Apremilast, multidrug therapy had better efficacy.

Background: Patients with hidradenitis suppurativa (HS) may have a higher risk of coronary artery disease (CAD) due to the excessive inflammatory burden. However, data on this association is still relatively limited. Aims: To investigate the association between HS and risk of prevalent and incident CAD by combining result from all available studies using systematic review and meta-analysis technique. Materials and Methods: Potentially eligible studies were identified from Medline and EMBASE databases from inception to November 2021 using search strategy that comprised of terms for 'hidradenitis suppurativa' (HS) and 'coronary artery disease' (CAD). Eligible study must be cohort study that consisted of one cohort of patients with HS and another cohort of individuals without HS. The study must report incidence or prevalence of CAD in both groups. The retrieved point estimates with standard errors from each study were summarized into pooled result using random-effect model and generic inverse variance method. Meta-analyses of the prevalent and incident CAD were conducted separately. Results: A total of 876 articles were identified. After two rounds of independent review by three investigators, seven cohort studies (four incident studies and three prevalent studies) met the eligibility criteria and were analysed in the meta-analyses. The meta-analysis found a significantly elevated risk of both incident and prevalent CAD in patients with HS compared to individuals without psoriasis with the pooled risk ratio of 1.38 (95% CI, 1.21–1.58; I² 83%) and 1.70 (95% CI, 1.13–2.57; I² 89%), respectively. Limitations: Limited accuracy of diagnosis of HS and CSD as most included studies relied on diagnostic codes and high between-study statistical heterogeneity. Conclusions: The current systematic review and meta-analysis found a significantly increased risk of both prevalent and incident CAD among patients with HS.

Chromoblastomycosis (CBM) presenting with linear distribution and with underlying bony destruction is rare. Herein, we report such a presentation in a farmer who presented with ulcerated nodules over the right leg and swelling of the right foot. Potassium hydroxide (KOH) preparation and histopathological examination of biopsy from nodule revealed characteristic sclerotic bodies on Gomori methenamine silver and periodic acid Schiff stain (PAS), which confirmed the diagnosis of chromoblastomycosis. X-ray of right foot revealed osteolytic destruction of right third metatarsophalangeal joint. Work-up for systemic involvement did not reveal any involvement. He was placed on combination therapy of itraconazole and terbinafine and is under follow-up.

Background: Vitiligo is a common depigmented skin disorder characterised by the selective destruction of melanocytes. Aims and Objectives: This study aimed to assess serum desnutrin and its association with insulin resistance in patients with vitiligo vulgaris. Materials and Methods: This study was a cross-sectional case-control study. It included 45 patients with vitiligo vulgaris and 45 age- and sex-matched healthy controls. Patients were subjected to complete general and cutaneous evaluations. All participants were subjected to the assay of fasting blood glucose (FBG), cholesterol, triglyceride, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), fasting serum insulin and serum desnutrin. Homeostasis Model Assessment + insulin resistance (HOMA + IR) was calculated for all participants. Results: There were statistically significant differences between the patients with vitiligo vulgaris and healthy controls regarding HDL, FBG, fasting insulin, HOMA-IR, and serum desnutrin (P < 0.001). Desnutrin levels were negatively correlated with FBS, LDL, VLDL, fasting insulin, and HOMA-IR (P < 0.05). Unlikely, the level of desnutrin had a positive, non-significant correlation with HDL (rho = 0.17, P = 0.059). Conclusion: This study concluded that in patients with vitiligo vulgaris, as a result of increased serum levels of glucose and insulin, the serum desnutrin was suppressed, perhaps contributing to hyperlipidaemia and IR. So, low serum desnutrin could be a biomarker for IR in patients with vitiligo vulgaris. A multidisciplinary approach is essential for the early detection of diabetes mellitus, IR and hyperlipidemia among patients with vitiligo vulgaris to avoid cardiovascular and metabolic complications.

Psoriasis is a chronic condition that progresses in remitting and relapsing phases. Most of these patients have mild-to-moderate illness, which can be managed with topical medications or could be thought of as continuing therapy after remission. Potential therapeutic efficacy is offered, and systemic treatment's negative side effects are constrained. Topical therapies have recently advanced in tandem with recent advancements in our understanding of psoriasis. To improve the quality of life of patients, appropriate knowledge and application of these topical agents are crucial.

The skin aging which entails modifications in the entire skin and skin support system is caused as a result of complex blend of intrinsic and extrinsic factors. The main objective of this review is to provide critical insights into the effect of the aging determinants (intrinsic and extrinsic) on aging skin and to focus on a few classes of natural bioactives that were reported to counteract symptoms of cutaneous aging, pose potential, and beneficial health effect on aging skin supported with relevant scientific evidence. The narrative review of this cutaneous antiaging study incorporating the literature findings was retrieved from the search of computerized databases PubMed and Scopus, hand searches, and authoritative books. The antiaging skin care approach of using bioactives are basically nutritional hormetins, available from our natural heritage, identified as potent free radical scavengers, antioxidants, moisturizers, cell repairing agents, and ultraviolet protectives which have started to seek considerable attention among researchers and consumers due to the undesirable effect of chemical-based constituents on human health and environment. With the booming antiaging strategies, beauty has become the prime factor in considering one's health and overall “wellness”. As promoting healthy aging is essential, the objective of aesthetic dermatology should shift from cosmetic interventions to the betterment of quality of life of aging society. The paper also discusses on certain artificial learning/machine-based algorithms, useful in screening of bioactive ingredients, helpful in developing of more tailored formulations. This narrative overview on skin antiaging natural bioactives and artificial learning–based bioactive screening approaches contributes for the improvement in dermatological drug discovery, in the development of novel targeted lead compounds and accelerates aging research and pharmaceutical research.

Tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is a member of the TNF superfamily (TNFSF). It acts through its receptor fibroblast growth factor-inducible 14 (Fn14). Studies have indicated that TWEAK/Fn14 pathway activation controls multiple cellular responses, including proliferation, angiogenesis and induction of inflammatory cytokines. TWEAK/Fn14 is manifested in many tissues of our body and most importantly in the skin causing inflammation and many autoimmune and neoplastic cutaneous disorders. Evidence suggests that the TWEAK/Fn14 axis, the downstream signalling pathway and its inflammatory molecular expressions are involved in the pathogenesis of many cutaneous disorders such as psoriasis, atopic dermatitis (AD) vitiligo and melanoma. So, this literature review describes a brief introduction of TWEAK and TWEAK/Fn14 pathway and summarises the case-series and open-label studies performed in the field of dermatology and its potential therapeutic benefit.

Background: Elafin is a serine protease inhibitor with anti-inflammatory properties. It is expressed in various epithelial tissues with increased production under inflammatory conditions. Increased tissue elafin expression in Behçet's disease (BD) lesions has previously been demonstrated. Aims and Objectives: We hypothesised that serum elafin might be increased in patients with BD and aimed to assess the relationship of serum elafin with disease activity and organ involvement in BD. Materials and Methods: Fifty-four BD patients (29 active, 25 inactive) and 30 healthy controls were included in this single-centre case-control study. Serum elafin was measured using ELISA. Complete blood count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) tests were also performed. Results: Serum elafin levels were significantly higher in patients with BD (1.58 ± 0.47 ng/ml, range: 0.67–2.96) compared to controls (1.10 ± 0.28 ng/ml, range: 0.65–1.49) (P < 0.001). Patients with active BD had higher elafin levels than patients with inactive BD (P = 0.008). Active arthritis was associated with an increase in elafin (P = 0.012), while the presence of mucocutaneous symptoms was not. Serum elafin correlated significantly with ESR (P = 0.001). The ideal cut-off value for the diagnosis of BD was determined as 1.24 ng/ml with a sensitivity and specificity of 72.2% and 70.0%, respectively. Conclusion: Serum elafin is significantly increased in patients with BD. It may serve as a marker of disease activity, especially articular involvement.

Dupilumab is a monoclonal antibody that inhibits interleukin-4 (IL-4) and interleukin-13 (IL-13), approved for the treatment of adults with moderate-to-severe atopic dermatitis (AD). While recent reports have described cases of new-onset mycosis fungoides (MF) following treatment with dupilumab for AD, to our knowledge only one patient has been delineated with the progression to SS. We present an additional case of a patient who was diagnosed with SS following treatment with dupilumab for adult-onset AD and asthma. We examine SS as a possible side effect of dupilumab while also discussing management and theories to explain this phenomenon.

Background: Genital dermatoses contain a group of diseases that affect the skin of the genital area. Genital dermatoses are classified as venereal and nonvenereal. They can affect a patient's life quality and can cause depression, anxiety and stress. Aims: This study aimed to evaluate and compare the quality of life index, depression, stress and anxiety in patients with genital dermatoses. Materials and Methods: Patients admitted to the dermatology outpatient clinic with genital skin complaints between October 2020 and March 2021 were included. A questionnaire including demographic information, a 10-item dermatology life quality index (DLQI) and a 21-item depression anxiety stress score (DASS-21) was filled out by the patients and was calculated. Results: A total of 103 patients were included in this study. Seventy-seven (74.8%) were male and 26 (25.2%) were female. A total of 48.5% (n = 50) patients had venereal genital dermatoses, and 51.5% (n = 53) of the patients had nonvenereal genital dermatoses. In the venereal diseases, syphilis had the highest DLQI, depression, anxiety and stress score while in the nonvenereal diseases, scabies had the highest DLQI, depression, anxiety and stress score. In the nonvenereal group, the mean DLQI score, depression, anxiety and stress scores were statistically significantly higher than the venereal genital dermatoses group (P < 0.01, P = 0.04, P = 0.03 and P = 0.02). Conclusion: The quality of life of patients with genital dermatoses is often poor, with significant levels of depression, anxiety and stress. We believe that screening these patients with DLQI and DASS-21 scores at their first admission and follow-up will benefit dermatologists and patients.

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:

1. To study the frequency of NAFLD in cases of chronic plaque psoriasis and controls
2. To study the interleukin levels in cases of chronic plaque psoriasis and controls.

Secondary objectives:

1. To study the BMI, lipid profile, waist circumference, FBS (fasting blood sugar), PPBS (post prandial blood sugar) and serum insulin in cases and controls
2. To 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 psoriasis
3. To correlate serum levels of IL1-β, 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- β, 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 – β, 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.

Background: The appearance of the scalp and hair is very important aesthetically regardless of age or sex. Although there are many drugs and treatment methods for scalp problems and hair loss, the treatment response is still insufficient. Aims and Objectives: To evaluate the efficacy of low-level light therapy in a helmet-like device. Materials and Methods: This study was designed as a 24-week trial with 50 participants. All participants used a helmet-shaped device emitting 630–690, 820–880, and 910–970 nm light wavelengths, for 20 minutes, daily for 24 weeks. A phototrichogram for hair density and thickness, Global Aesthetic Improvement Scale score, erythema index, and sebum secretions of the scalp were evaluated at baseline and at 12 and 24 weeks. Results: After 24 weeks of treatment, hair density and hair thickness were found to have significantly increased (P <.01 and P =0.013, respectively) and sebum secretion of vertex area had decreased significantly (P <.01). Of 49 participants, 73.47% of the participants showed improvement in the overall appearance of the scalp (n = 36). Conclusion: A helmet-like low-level light therapy device can improve the appearance of the hair, with thickening and increase in the density of the hair, and can improve scalp condition by decreasing sebum secretion.

Background: Oral lichen planus (OLP) is an autoimmune disease primarily affecting the middle-aged females. The present study aims to determine the relation of the oestrogen receptor alpha (ERα) with OLP pathogenesis, correlating it with the possible cause of its higher prevalence among females. Materials and Methods: Clinically and histologically identified fifteen of each pre-menopausal and peri-menopausal OLP female patients were chosen for this study. The expression of ERα was analysed from the collected lesion tissue samples by using two-step semi-quantitative reverse transcriptase polymerase chain reaction (SqRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Results: mRNA and protein expression of ERα were significantly higher in both groups of OLP female patients when compared with the control. The perimenopausal OLP patients showed significantly elevated expression of ERα compared to premenopausal patients. Conclusion: Higher expression of ERα in pre- and peri-menopausal females may be a causative factor for the higher prevalence of OLP among females.

Purpose: This study aimed to explore the clinical effects of pulsed dye laser (PDL) dynamically combined with triamcinolone acetonide (TAC) in the treatment of post-operative keloids recurrence. Materials and Methods: This study retrospectively analysed the clinical data of 29 keloid patients (with 39 keloids) from April 2014 to February 2020. The patients were divided into TAC group (14 patients with 19 keloids) and dynamic treatment group (15 patients with 20 keloids) according to the post-operative treatment that they received. The keloids were assessed by Vancouver scar scale (VSS), patient and observer scar assessment scale (POSAS) and the effect of keloids on the quality of life of patients was evaluated with dermatology life quality index (DLQI) scale before the surgical treatment, at any time of relapse, and 24 months after the surgical treatment. The recurrence-free interval, relative cure time, and the cumulative times of TAC injection when the relative cure could be assessed as achieved, and the incidence of adverse reactions were calculated. Results: Patients experiencing a recurrence within 2 years after surgery included 19 keloids (25.33%) that developed a recurrent event within 6 months, 34 keloids (45.33%) that within 12 months, and 39 keloids (52.00%) that within 24 months after surgery. Anterior chest keloid had the highest recurrence rate and ear keloid had the lowest recurrence rate. The total pigmentation and vascularity (VSS and POSAS) scores of patients' keloids in TAC group and dynamic treatment group 24 months after treatment were significantly lower than those before treatment and at relapse (P < 0.05), the total VSS and POSAS scores were significantly lower at 24 months than before treatment and at relapse (P < 0.05), and the DLQI scale score was significantly lower at 24 months than before treatment (P < 0.05). The VSS and POSAS scores of patients' keloids at 24 months after treatment were significantly lower in the dynamic treatment group than in the TAC group. The relative cure time of patients' keloids in the dynamic treatment group was 6.47 ± 2.72 months, which was significantly shorter than 8.65 ± 3.67 months in the TAC group (P < 0.05). The cumulative number of TAC injections that were given to achieve a relative cure of patients' keloids in dynamic treatment group was 3.60 ± 1.76, which was significantly less than 5.24 ± 2.25 in TAC group. The total incidence of adverse reactions was lower in the dynamic group than in TAC group, but this difference did not reach statistical significance (P > 0.05). Conclusions: Compared with TAC injection alone, PDL dynamically combined with TAC in the treatment of keloid with post-operative recurrence can shorten the relative cure time, reduce the number of TAC injections and improve the clinical efficacy.

Atopic dermatitis (AD) is a common chronic dermatological condition affecting ~10% of adults and ~20% of the paediatric population in high-income countries. There is a lack of comprehensive understanding of the disease burden of AD in India. In this systematic review, the primary objective was to review epidemiological data on AD in India based on articles published between 2011 and 2021. The secondary objective was to assess the disease burden from economic and quality of life (QoL) perspectives. A literature search was conducted using the PubMed and Google Scholar databases using predefined search strings. Relevant studies published in English on AD between 2011 and 2021 were included. This review included 11 articles, of which nine reported demographic and clinical characteristics. The reported prevalence ranged from 3.1% to 7.21% among the paediatric population, up to 16 years of age. The prevalence of AD ranged from 0.98% to 9.2% in studies including paediatric and adult patients. The cost of medications was reported to be the major contributor to the economic burden associated with AD. Mental illnesses such as depression and anxiety were frequently reported in association with AD. Although AD is a common disorder affecting all age groups, there is a lack of substantial epidemiological data. None of the current studies covers the entire country. Hence, studies with a wider geographic scope covering all aspects of disease burden are required to help clinicians and policymakers to understand the disease burden and devise appropriate preventive and management strategies.

Background: Psoriasis is a chronic immune-mediated inflammatory disease affecting the skin and/or joints. MicroRNAs (miRNA) are single-stranded non-coding RNA molecules that bind to messenger RNA (mRNA) and regulate gene expression. Studies on peripheral blood mononuclear cells (PBMCs) in psoriatic patients showed an upregulation of miRNA 223. Aims and Objectives: a) To estimate and compare the expression of miRNA 223 in cases of chronic plaque psoriasis and controls. b) To correlate the expression of miRNA 223 with the severity of chronic plaque psoriasis. Materials and Methods: This study included 80 subjects (40 with psoriasis and 40 with age- and sex-matched healthy controls) attending the dermatology OPD of a tertiary care hospital from January 2018 to June 2019. A detailed history, determination of Psoriasis Area Severity Index (PASI) score and estimation of miRNA 223 by quantitative real-time polymerase chain reaction (qRT-PCR), was done in all subjects. Results: The expression of miRNA 223 (ΔCt) was higher in cases than in controls. The observed mean ΔCt was higher in severe (12.90 ± 0.46) than in mild (9.81 ± 1.70) and moderate (10.58 ± 1.26) psoriasis. The difference in expression of miRNA with varying severity of psoriasis was significant. The mean difference of ΔCt between mild to severe was (3.09) (P ≤ 0.001) and moderate to severe was (2.31) (P = 0.013). Among cases, the expression of miRNA 223 was higher in those exhibiting Koebner's phenomenon compared to those without Koebner's phenomenon (P = 0.0424). Conclusion: Expression of miRNA 223 was higher in psoriatic patients than in controls and the expression increased with the severity and activity of the disease suggesting the upregulation of miRNA 223 with the progression and activity of the disease.

Context: Photoaging correlates with ultraviolet radiation (UVR). In addition to direct and indirect DNA damage, UVR leads to a breakdown of collagen, resulting in enlarged pores, visible wrinkles, also uneven skin tones and pigmentations. Amniotic membrane stem cell (AMSC) can be a useful modality in cell regeneration. Vitamin C has been known as an agent of depigmentation, antioxidants, and collagen synthesis. A topical combination of amniotic membrane stem cell-conditioned medium (AMSC-CM) and vitamin C is expected to improve photoaging. Fractional CO₂ laser and microneedling served as transdermal drug delivery. Aims: To compare between microneedling and fractional CO₂ laser for the administration of AMSC-CM and vitamin C in photoaging treatment. Methods and Material: Sixty Indonesian women with photoaged skins participated in this experimental analytic, controlled, matching research and were divided into two groups. Thirty women received fractional CO₂ laser, and others received microneedling. All participants received a topical combination of AMSC-CM and vitamin C. Three treatment sessions were repeated at a four-week interval for fractional CO₂ laser and a two-week interval for microneedling. We evaluated the progression and side effects using a skin analyzer on weeks 0, 4, and 8 for the microneedling group and for the fractional CO₂ laser group on weeks 0, 4, and 12. Results: Assessment of wrinkles, UV spots, skin tone, and pore revealed a statistically significant effect of a topical combination of AMSC-CM and vitamin C after fractional CO₂ laser (p < 0.05). Conclusions: Combination of AMSC-CM and vitamin c using fractional CO₂ laser can improve photoaging and is better compared to microneedling.

To study the clinical profile, risk factors and complications of paediatric Herpes zoster ophthalmicus (HZO). Case records of clinically diagnosed paediatric HZO over the past five years period were collected. An analysis was done with the existing data to determine the patient's clinical presentation, risk factors and treatment outcomes. Among seven children (three males and four females), two were less than ten years. Risk factors like previous history of chickenpox were present in one patient and immunosuppression in another. Child with immunosuppression also had h/o viral encephalitis three days before the onset of HZO. While two patients presented with disciform keratitis and three with anterior uveitis, the remaining did not have anterior segment involvement. Six out of seven patients retained 6/6 visual acuity at one month follow-up. Paediatric HZO is prevalent even in immunocompetent children without any identifiable risk factor. It generally has a good prognosis with minimum residual complications.

Background: Autoimmune connective tissue diseases (AICTD) present with a myriad of clinical manifestations, including cutaneous. These disorders occur because of immune dysregulation that produces autoantibodies targeting connective tissue and internal organs. Screening these autoantibodies not only aids in the diagnosis but also in predicting specific organ involvement and the risk of complications related to the disease. Aims: This study was conducted (a) to study various cutaneous and systemic manifestations of AICTD, (b) to study the antinuclear antibody (ANA) profile and (c) to determine the association between systemic manifestations and antinuclear antibodies. Methodology: Thirty cases of autoimmune connective tissue disease were recruited for the study. A physical examination, clinical profile and ANA profile were done. Results: Nonscarring alopecia (83.3%) was the commonest cutaneous manifestation noted, followed by photosensitivity (73.3%). The most common system affected was musculoskeletal (67%), followed by renal (40%). Anti-dsDNA antibodies were significantly associated with musculoskeletal involvement (85%) with a P value of 0.038 and anti-Sm antibodies with neurological involvement (87%), followed by renal involvement (75%) with a P value of 0.018 and 0.001, respectively. Anti-SCL 70 antibodies were significantly associated with lung involvement (75%), with a P value of 0.009 and the presence of anti-SS-A antibodies with cardiovascular involvement (40%) with a P value of 0.014. Conclusion: Antinuclear antibodies are diagnostic as well as prognostic biomarkers for AICTD and contribute to precision medicine. These antibodies serve as markers to pursue involvement of organs, which in turn helps the treating physician to choose appropriate preventive measures.

Background: Vitiligo, a multifactorial, depigmented skin disease, is characterised by selective loss of functional melanocytes leading to pigment reduction in the affected areas of the skin. Aim: We aimed to examine thiol-disulphide homeostasis, IMA, copper, zinc, selenium, vitamin A and vitamin C levels in vitiligo patients. Materials and Methods: The study included 83 vitiligo patients and 72 healthy controls. Copper, zinc, and selenium levels were measured by atomic absorption spectrophotometer; vitamin A and E levels were measured by high-performance liquid chromatography. Ischemia-modified albumin and native/total thiol levels were measured by colourimetric method. Results: Serum native and total thiol levels were significantly lower in vitiligo patients (P < 0.001, for all). Zn levels were significantly higher in vitiligo patients than in the control group (P = 0.004). There was no statistical difference in terms of Cu, Se, vitamin A and vitamin E levels. Conclusions: All thiol-disulphide homeostasis parameters (the most important antioxidant–oxidant system in circulation), trace elements, and vitamins together were evaluated in the present study in vitiligo patients. It can be concluded that vitiligo patients have increased oxidative stress status, and also the increase in the dissemination of the disease also increases the oxidative stress in the body.

Extramammary Paget's disease is an intraepithelial neoplasm, usually found in areas rich in apocrine gland concentration. The clinical features, histopathology, immunohistochemistry and management details of five patients (F = 3, M = 2) have been described here. While a well-defined persistent plaque with crusting and erosion was the most common presentation, hyperpigmentation, hypopigmentation and depigmentation were also observed in two patients. Characteristic Paget's cells with cytokeratin 7 and EMA positivity were seen on histopathology examination. Authors conclude that pigmentary alterations may be under-reported in extra mammary Paget's disease in the skin of colour.

Background: Activation of the NLRC4 inflammasome appears to start many signalling processes inside the host, including caspase-1, the principal protease responsible for converting proIL-1β and IL-18 to active, secreted IL-1β and IL-18, resulting in pyroptosis. Aims: To evaluate NLRC4 level in patient's blood serum to highlight its role in the pathogenesis of leprosy. Materials and Methods: This prospective study was conducted on 40 patients with leprosy and 30 healthy individuals of matched ages and sexes. All patients were subjected to complete history taking, general and dermatological examination, laboratory investigations, slit skin smear with bacillary index, and clinical classification of the studied leprosy group patients regarding disability according to disability grading. And finally, measurement of serum NLRC4 level by ELISA. Results: In the paucibacillary (PB) group, NLRC4 serum level ranged from 0.9 to 1.8 ng/ml with 1.43 ± 0.28 ng/ml, while in the multibacillary (MB) group, it ranged from 1.2 to 5.7 ng/ml with 2.83 ± 1.11 ng/ml. NLRC4 serum level had increased significantly in MB patients compared to PB patients (P < 0.05). There was a significant difference among the three studied groups, regarding the serum level of NLRC4 (P < 0.05). In leprosy patients, significant positive correlations were found between serum levels of NLRC4 and bacillary index and duration of leprosy. Conclusions: Leprosy patients had considerably greater serum levels of NLRC4 than controls. It was much greater in MB patients than in PB patients.

Background: Vitiligo is an acquired chronic autoimmune skin disorder with an estimated prevalence of 1% worldwide. The CD8⁺ T-cell-mediated chemokines such as CXCR3, CXCL9 and CXCL10 are the non-specific action immunomodulators that are responsible for the depigmentation and progression in vitiligo. Aim: This study aimed to explore the expression levels of serum CXCL9-11 in vitiligo patients who received the transplantation of cultured autologous melanocytes (TCAMs) before and after the operation and correlate their expressions with clinical stage, subtype and course of the vitiligo disease. Materials and Methods: The expression levels of serum CXCL9-11 were measured in the peripheral blood of 26 progressive vitiligo patients, 24 stable vitiligo, 13 TCAM patients and 30 healthy control (HC) cases using enzyme-linked immunosorbent assay (ELISA). The potential correlations between their expressions and disease features such as stage, type and surgical treatment were evaluated using Student's t-test. Results: The expression levels of serum CXCL9-11 increased by ~1.4, ~1.6 and ~2.3-fold in vitiligo patients compared with HCs (P < 0.01). The expression levels of all chemokines were significantly higher in progressive vitiligo patients than in stable vitiligo (P < 0.01). The increasing expression levels of serum CXCL9, CXCL10 and CXCL11 were significantly related to the different types of vitiligo patients (P < 0.05). Preoperative expression levels of serum CXCL9-11 were significantly higher than the post-operative expression levels (P < 0.01). Conclusion: Our results demonstrate that increasing expression levels of the CXC family play a key role in the immunopathogenesis of vitiligo. The abnormal expression of the CXC family may be considered an effective and therapeutic target for TCAM treatment.

The study of antimicrobial-resistant Propionibacterium acnes was not conducted regularly, especially in Indonesia. Conversely, regular monitoring of antibiotic efficacy through in vitro testing to assess the evolution of current resistance patterns is obligated; thus, filling the gap caused by a lack of appropriate antibiotic surveillance is required. Analyse the correlation between resistance patterns of P. acnes to doxycycline, clindamycin, erythromycin and azithromycin with the severity of acne vulgaris. This is an analytic observational laboratory study with a cross-sectional design of mild to severe acne vulgaris (AV) patients. Specimens were obtained from comedones of 71 patients, which were cultured and identified using biochemical examination. Antimicrobial resistance (doxycycline, clindamycin, erythromycin and azithromycin) to P. acnes was tested by disc diffusion method. Among 71 samples collected, 40 (56.3%) P. acnes isolates were cultured and identified. The incidence of P. acnes resistance to more than one antimicrobial was 45%. Antimicrobial resistances were clindamycin 42.5%, erythromycin 40%, azithromycin 23.5% and doxycycline 12.5%, respectively. According to the contingency coefficient test, there was moderate correlation between the resistance pattern of P. acnes to clindamycin (r = 0.485, P = <0.001) and doxycycline (r = 0.433, P = 0.002) and AV severity. There was weak correlation between the resistance pattern of P. acnes to erythromycin (r = 0.333; P = 0.025) and azithromycin (r = 0.321; P = 0.032) and AV severity. In conclusion, there is a correlation between the pattern of P. acnes resistance to doxycycline, clindamycin, erythromycin, azithromycin and severity of AV.

Background: Microsporum canis (Bodin, 1902) is a dermatophyte, which is widely represented in the developing and the developed world alike. Commonly transmitted from domestic animals it is particularly dangerous for immunosuppressed patients due to AIDS, cancer or transplant surgery. Search for new perspective antimycotic derivatives becomes an urgent task in the disease containment. Previously, several quinolinium analogs were screened for their antibacterial activity (E. coli, St. aurous) by our research team. Furthermore, some N-phenylbenzoquinaldinium derivatives have shown antifungal activity against Candida albicans and Candida krusei. Aims: In this study, we sought to investigate fungicidal properties of N-arylbenzoquinaldinium derivatives against a clinical strain of Microsporum canis for future medicinal applications. Materials and Methods: N-phenyl-[f]-benzoquinaldinium salts were prepared by a variation of the previously described technique and tested against a clinical strain of the fungus of Microsporum canis 114 harvested from pathogenic material of a patient (Perm, Russia, 2014). Results: N-phenyl-[f]-benzoquinaldinium tetrafluoroborate has shown antifungal activity par to (or exceeding) that of commercially available medication. Moreover, this benzoquinaldinium analog can be potentially labelled with tritium by our nuclear-chemical method, making it amenable for the sensitive pharmacokinetic studies. Conclusions: N-phenyl-[f]-benzoquinaldinium tetrafluoroborate has been shown as a promising compound for the further development of potent antifungal agents as well as radiotracers for further elucidation of biological pathways of antifungal activity.

Context: Many therapeutic modalities have been reported for the treatment of warts: a common bothersome condition; however, no single treatment is completely effective. Aims: This study aimed to evaluate the efficacy and safety of intralesional injection of measles, mumps and rubella (MMR) vaccine and to compare its efficacy with 85% formic acid puncture for common warts. Settings and Design: This was a prospective comparative study. Methods and Material: A total of 60 patients, divided into two groups, were included in the study. Group A received an intralesional MMR vaccine of 0.3 ml per lesion, and group B received 85% formic acid puncture into each lesion with a maximum of 10 warts treated in each case. Five sessions were conducted every 2 weeks in each case with a follow-up period of 3 months to check for recurrence. Statistical Analysis Used: The Chi-square test, Fisher's test and t-test were used for statistical analysis. A P-value <0.05 was considered statistically significant. Results: In group A, the complete response was observed in 62.5%, partial response in 8% and no response in 4.1% of patients. In group B, the complete response was observed in 31.8%, partial response in 63.6% and no response in 4.5% of patients. The difference in cure rates was found to be statistically significant with a P value of 0.031. No recurrence was observed in both groups in the follow-up period. Conclusions: Immunotherapy by intralesional MMR vaccine is a simple, well-tolerated, effective and cost–benefit modality for the treatment of warts and showed a statistically significant cure rate than formic acid therapy.
