ABSTRACT
This report delineates two instances of dermatitis artefacta (DA), a psychodermatological condition marked by self-induced or exacerbated skin lesions. These cases, triggered by treatments from non-qualified practitioners, highlight the critical need for healthcare professionals to discern the potential repercussions of unsound medical guidance.
ABSTRACT
Background: Amyloidosis, deposition of misfolded protein in body, is a fairly common condition. The deposition of misfolded proteins in skin which occurs in absence of systemic comorbidities, namely Primary Cutaneous Amyloidosis (PCA) is also a well-known entity in skin of colour patients of Asian subcontinent. Primary Cutaneous Amyloidosis is usually diagnosed with good clinical acumen and typical clinical phenotype and involved site. Dermoscope has been used as an adjunct non-invasive tool to confirm cases with diagnostic uncertainty and in those in whom biopsy is deferred. Typical dermoscopic features of PCA helps differentiate it from other pigmentary dermatoses and avoids unwanted invasive biopsies and investigations especially in resource poor settings with financial constraints. Objectives: This study aims to identify and corroborate clinically, typical dermoscopic features in PCA in 42 patients which includes Macular Amyloidosis (MA) and Papular Amyloidosis (PA) predominantly in skin of colour patients from government based hospital of a south east Asian country. Materials and methods: Patients with classic clinical features of PCA were selected. Primary Cutaneous Amyloidosis was subclassified into MA or PA and their corresponding clinically corroborative dermoscopic features were enlisted respectively. All patients (treatment naïve and previously treated), who consented to participate in the study were included. Patients were diagnosed based on the prototypical clinical features. Dermoscopy was done using DermLite III DL3N Polarised and Fluid Dermoscope w/PigmentBoost Brand (3Gen, DermLite LLC, San Juan Capistrano, CA, USA) and images were obtained to create digital dermoscopy system by attaching camera-equipped mobile device via an optional connection kit (Redmi Note 11, MIUI version 13.0.5, CHINA) and the findings were enlisted concurrently. Results: In this study of dermoscopic findings of PCA, 42 patients were evaluated for their clinical lesions along with its corroboration with the dermoscopic features. Macular Amyloidosis was seen in 30 patients and 12 patients had typical cutaneous phenotypic and dermoscopic feature of PA. The most common dermoscopic finding seen in patients with MA was shiny to dull white, circular or oval central hub surrounded with halo of light brown dots. Most common configuration of brownish pigmentation around central hub was fine streak type. Also eccrine clues were seen in some cases of MA, which was a unique finding. Similarly in the PA subtype, the central hub was replaced by scar like structureless translucent white area surrounded by brownish black dot like structures, especially in those with large and thick plaques. Conclusion: Dermoscopic findings of PCA and their clinical corroboration is a much-needed aspect in treating patients with pigmentary disorders and in those with skin of colour, especially in developing countries. Utilization of dermoscope in clinical settings of low income countries and in government based hospitals will decrease the add on economic burden of invasive diagnostic modalities like biopsy and other inadvertent tests done to rule out pigmentary conditions.
ABSTRACT
Background: The socio-environmental aspects of southern Assam reflect a general pattern of backwardness. Moreover, child healthcare resources in the region are inadequately used, leading to low vaccination coverage. Given this background, this paper attempted to comprehend wealth-based inequality in full vaccination in rural areas of southern Assam. Methodology: Based on a multistage cluster sampling approach, 360 children of 12-23 months were selected from the study area. To identify the predictors of a child, a non-linear model was estimated by using the generalized linear model (GLM) approach followed by Erreygers decomposition technique to quantify the wealth inequality in the obtained predictors in explaining the disparity in full vaccination. Result: The Bacillus Calmette-Guérin (BCG) vaccination recorded the highest vaccination coverage, at nearly 90% and the lowest was observed for the measles vaccine, around 61 percent. Slightly more than half of the eligible children (54 percent) were vaccinated against all the Universal Immunization Programme (UIP)-recommended vaccines. The decomposition analysis revealed that the occupation of the child's father, maternal age, birth order of the child, and health-seeking behavior such as antenatal care (ANC) were the prime factors related to inequality in full vaccination in the region. Conclusion: Vaccination coverage in the region has improved over time, however, full vaccination is concentrated towards the economically advantaged section of the society in rural southern Assam. Targeted, context-specific, and expanded government initiatives could aid in addressing the overall wealth-related full vaccination inequalities in the valley.
ABSTRACT
INTRODUCTION: The skin is frequently subjected to a variety of environmental trauma and stress. It is unavoidably subjected to blue light due to the increased use of electronic equipment, including indoor lighting and digital gadgets like smartphones and laptops, which have a range of detrimental effects. The method of action and numerous harmful consequences of blue light on the skin are the main subjects of this review. MATERIALS AND METHODS: A literature search has been performed using PubMed, GoogleScholar and EmBase databases and an updated review on the topic has been presented. RESULTS: Numerous studies have shown that being exposed to blue light accelerates the aging process and produces cutaneous hyperpigmentation. It also modifies the circadian rhythm. The two main molecules that mediate cellular responses to blue light are nitric oxide (NO) and reactive oxygen species. However, the precise process is still not fully known. CONCLUSION: These negative consequences may eventually cause more general skin damage, which may hasten the aging process. At times, skin protection may be crucial for protection against blue light.

BACKGROUND: Cutaneous sarcomas are uncommon cancers that can have a wide range of clinical symptoms and lead to considerable cutaneous as well as systemic morbidity. AIM: The objective of this review article is to discuss epidemiology, clinical features, diagnosis, and therapy of different types of cutaneous sarcomas. MATERIAL AND METHODS: Literature was screened to retrieve articles from PubMed/Medline and Google Scholar and related websites. Cross-references from the relevant articles were also considered for review. Review articles, clinical studies, systematic reviews, meta-analyses, and relevant information from selected websites were included. RESULTS AND DISCUSSION: Cutaneous sarcomas have a negative effect on the quality of life. In their diagnosis, clinical presentation and histological evaluation are crucial. Complete surgical removal is the solution for more or less all cutaneous and subcutaneous sarcomas. The prognosis for cutaneous sarcomas is generally favorable since they tend to recur locally with distant metastases only on rare occasions. Patients having advanced disease should be treated in the setting of clinical trials if possible; choices include radiation therapy and systemic medicines. The value of innovative immunotherapy cannot be determined decisively at this time due to a paucity of relevant trials. CONCLUSION: As cutaneous sarcomas are rarely diagnosed based on clinical findings, histology plays an important role in the diagnosis. They have a relatively favorable prognosis if treated properly. Patients should be treated at specialized centres.

BACKGROUND: The humans have been disproportionately affected by the coronavirus disease (COVID-19) pandemic. The novel coronavirus or the severe acute respiratory syndrome coronavirus 2 (SARS-COV2) causing coronavirus disease (COVID-19) has spread across the globe. Androgens have been suggested to have a role in COVID-19 pathogenesis. OBJECTIVE: The objective of this review article is to study the link between androgens and COVID-19. METHODOLOGY: PubMed and Google Scholar search was performed to retrieve literature related to the topic. Review articles, clinical trials, retrospective studies, observational studies, and case-control studies were considered for the review. RESULTS: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected men are more inclined to be hospitalized for intensive care unit (ICU) as compared with women. This difference in the ICU admissions provides some clue for possible influence of androgens in the severity of COVID-19. The contribution of androgen and androgen receptor in COVID-19 disease and its severity, as well as the numerous medications targeting androgen and its receptor for lowering COVID-19 disease severity, are discussed in this review. Available literature suggests the role of androgen in the pathogenesis and severity of COVID-19. Sensitivity for androgen may be an important factor in regulating the severity of COVID-19 disease. CONCLUSION: There is a scope for the development of COVID-19 treatments based on androgen suppression. Clinical trials may furnish pivotal data and add more evidence-based options for the management of COVID-19.

Erythroderma is usually attributed to some of the commoner causes such as eczematous disorders, psoriasis, malignancies, idiopathic situations and drug-induced scenarios. Rarely, erythroderma has been found to result from dermatophytic infections. Erythrodermic dermatophytosis may be a direct sequel of extensive tinea corporis (with or without a background of topical steroid misuse), paraneoplastic phenomenon, an id reaction or congenital erythrodermic disorders, with subsequent development of dermatophytosis. We present a series of patients who developed erythrodermic dermatophytosis on a background of misuse of steroids.

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder of the apocrine glands characterized by recurrent episodes. Although several therapies exist, none is completely curative. Several immunosuppressives have been studied with encouraging results and targeted approaches. In this review, we highlight the various immunosuppressives used in this condition along with their salient features to enable physicians to choose the correct therapy for their patients. The search of the peer-reviewed literature included clinical trials, scientific reviews, case series, case reports, and guidelines. The literature was identified from electronic databases (MEDLINE and PubMed) through November 2021; additional articles were included from the references of the identified articles.
ABSTRACT
INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory skin disorder associated with intense itch/pruritus and skin lesions. Several modalities of treatment including topical therapy, systemic agents, and biologics are available for the treatment of disease. Despite this, management poses challenge due to chronic nature and recurrent episodes in many patients. Biologics represent an important option of treatment for patients who do not respond to the traditional treatment. AREAS COVERED: In this article, we focused on efficacy and safety of biologics in the treatment of atopic dermatitis. Other therapies are out of the scope of this review. Articles from PubMed and Google scholar and cross references of retrieved articles were used to write the narrative review. EXPERT OPINION: Biologics play an important role in the treatment of atopic dermatitis. Every biologic has its own place in the treatment considering pharmacological profile, efficacy, and safety. Several biologics have been studied in the treatment of moderate-to-severe cases who failed to provide adequate response to traditional treatment. Dupilumab, is approved for the treatment of moderate-to-severe atopic dermatitis. Tralokinumab and nemolizumab have shown promising results in patients with atopic dermatitis.

Artificial intelligence (AI) has wide applications in healthcare, including dermatology. Machine learning (ML) is a subfield of AI involving statistical models and algorithms that can progressively learn from data to predict the characteristics of new samples and perform a desired task. Although it has a significant role in the detection of skin cancer, dermatology skill lags behind radiology in terms of AI acceptance. With continuous spread, use, and emerging technologies, AI is becoming more widely available even to the general population. AI can be of use for the early detection of skin cancer. For example, the use of deep convolutional neural networks can help to develop a system to evaluate images of the skin to diagnose skin cancer. Early detection is key for the effective treatment and better outcomes of skin cancer. Specialists can accurately diagnose the cancer, however, considering their limited numbers, there is a need to develop automated systems that can diagnose the disease efficiently to save lives and reduce health and financial burdens on the patients. ML can be of significant use in this regard. In this article, we discuss the fundamentals of ML and its potential in assisting the diagnosis of skin cancer.
