A Study to Describe the Pattern of Cutaneous Adverse Effects of COVID-19 Vaccines (Covishield and Covaxin).

Background: Vigorous administration of COVID-19 vaccines to tackle the ongoing pandemic has led to increasing research on adverse effects including both systemic and cutaneous. Objective: A prospective observational study to delineate the cutaneous adverse effects of two vaccines, namely Covishield and Covaxin, administered in two doses in northern India. Materials and Methods: The study was conducted in a tertiary hospital in northern India wherein patients were asked to report voluntarily any cutaneous adverse effects after COVID-19 vaccination to the dermatology department. The data were collected using excel sheets and later analyzed taking into consideration the age, vaccine types, and duration of onset of adverse effects. Results: Of the 19,672 vaccination jabs, 296 (1.5%) developed cutaneous adverse effects of which the incidence was higher in Covishield vaccine group compared to Covaxin vaccine group. The incidence of side effects was more with the first dose of either vaccine compared to the second dose. All the side effects were benign and were managed symptomatically or were self-limiting. Limitations: The number of vaccine recipients was limited and there was a considerable overlap of adverse effects with both vaccines. Voluntary reporting of cases is not an accurate representation of the scale of patients with adverse effects. Conclusion: Rampant administration of vaccines along with widespread advertisement of vaccine-induced side effects via social media has created apprehension in the general population. This warrants studies improving awareness about the most vital preventive measure available to halt and eventually end the COVID-19 pandemic.

Palmoplantar Plaque Psoriasis is Associated with Diabetes, Hypertension, Obesity, and Metabolic Syndrome-A Case-Control Study.

Background: Palmoplantar plaque psoriasis is a regional variant of psoriasis, characterized by erythematous, indurated plaques with fissuring over palms and soles. Chronic plaque psoriasis is associated with various comorbidities such as obesity, diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome, and cardiovascular disease. Body surface area involvement is an indicator of psoriasis severity, and most comorbidities are more strongly correlated with severe disease. Objectives: To estimate the prevalence of metabolic comorbidities in palmoplantar plaque psoriasis. Methods: It is a case-control study involving treatment naïve palmoplantar plaque psoriasis patients and age- and gender-matched healthy controls. Results: The study included 100 cases and 100 controls. The mean age among cases and controls was 45.4 ± 11.1 and 43.9 ± 10.3 years, respectively (P: 0.31). The gender ratio among cases and controls was 1.56 (61M: 39F) and 1.94 (66M: 34F), respectively. Comorbidities including metabolic syndrome (P: 0.001), obesity (P: 0.001), diabetes mellitus (P: 0.001), and hypertension (P: 0.001) were more common among cases as compared to controls. The odds of diabetes, metabolic syndrome, hypertension, and obesity in patients with palmoplantar psoriasis were 4.8 (95% CI 2.5-9.3), 3.7 (95% CI 2-6.9), 3.1 (95% CI 1.6-6), and 3.5 (95% CI 1.9-6.4), respectively. Conclusion: In this study, we found that palmoplantar plaque psoriasis is associated with metabolic comorbidities. Primary care physicians should screen patients with palmoplantar psoriasis for these comorbidities.

An observational study on ocular manifestations in patients of psoriasis in a tertiary care hospital in western India.

Background: The aim of the study is to observe the ocular manifestation in patients of psoriasis. Methods: All the diagnosed cases of Psoriasis by the dermatology department of this tertiary care hospital were included in this study. Relevant details of the history pertaining to disease duration, type of psoriasis, and treatment undertaken including ocular symptoms were obtained. Disease severity was quantified using the PASI score. Complete ocular examination including intraocular pressure, Schirmer I and II tests, Tear Film Breakup Tme (TBUT); was carried out for all the patients. Results: Of 126 patients of psoriasis, ocular manifestations were seen in 76 patients (60.3%). Dry eyes (27%) and blepharitis (15.9%) were the most common ocular manifestations. Uveitis was seen in 3.2% of the patients of which 75% patients were HA B27-positive psoriatic arthritis, which was statistically significant (p = 0.001). There was no statistical correlation between duration of the disease and ocular manifestations (p value is 0.077 using chi square test). The ocular manifestations were more common in patients with PASI score 10 when compared with the patients with PASI score 10 (p value = 0.028) which was statistically significant. Conclusions: In our study, prevalence of ocular manifestation was 60.3% which increased with the increasing PASI score. Dry eyes and blepharitis were the most common manifestations. Hence, routine ocular examination is recommended in patients with psoriasis.

Emerging drugs for the treatment of acne: a review of phase 2 & 3 trials.

INTRODUCTION: Acne vulgaris is one of the commonest dermatoses encountered in a dermatology clinic. Although the inflammatory processes are centered around the pilosebaceous unit, a myriad of external factors that alter the pathogenesis have been hypothesized. Newer therapies are focused on targeting these as possible scaffolds for drug development. Existing topical and oral medications have considerable overlap between pharmacotherapy and cosmeceuticals directed toward acne treatment making new drug development extremely competitive and financially burdening. Teratogenicity associated with retinoids, cutaneous adverse effects of topical anti-acne medications, and lack of long-term remission induction are a few hindrances that have to be tackled by novel therapies. AREAS COVERED: Numerous topical and systemic medications for acne vulgaris are undergoing clinical trials presently. The review has dealt with anti-acne drugs undergoing phase II and III clinical trials with emphasis on the rationale of various combinations in tandem with the complex pathogenesis of the disease. EXPERT OPINION: The current strategies in new drug development target sebocyte function, neo-inflammatory mediators, and methods combatting drug resistance while broadening the anti-microbial spectrum against Cutibacterium acnes. A holistic approach is pivotal to strengthen the management protocol for acne to achieve precision dermatological practice.

Resurgence of syphilis, the great imitator.

Syphilis, one of the earliest diseases to be discovered in humans, still remains an enigma when it comes to its myriad manifestations and changing epidemiological profiles. There has been a surge in cases in the last few decades due to various factors. The human immunodeficiency virus (HIV) epidemics, global travel, increased incidence of male to male sexually transmitted diseases, online relationships culminating in casual sex are few of the important factors. Increased awareness could also be a factor for increased diagnosis. The multitude of clinical features especially when it comes to secondary syphilis and the rare tertiary manifestations, which can mimic various systemic disorders still pose a diagnostic challenge to the best of venereologists and physicians. This review aims to discuss the causes of resurgence in syphilis and few recent developments in pathogenesis, which could have led to this resurgence.
