Context: Inguinal skin is prone to various infectious dermatological conditions such as erythrasma, intertrigo, hidradenitis suppurativa, folliculitis, dermatophytic infection, and various sexually transmitted diseases, as compared to the skin elsewhere. Aim: Our study attempts to compare the biophysical profile parameters (BPPs) of the genital skin with that of the rest of the body, while taking skin of the upper back as control. It also attempts to find out if there is a difference in BPPs of the two sites and that how the change in the BPPs, bring about change in microbiome and make inguinal skin more prone to infections. Materials and Methods: This was a hospital-based comparative study conducted over 976 patients (600 males and 376 females) of age group 18–60 years, where BPP parameters such as hydration, skin pH, transepidermal water loss (TEWL), and sebum content were measured over the skin of the upper back and right inguinal region, and the results were summarized and presented as proportions (%). Chi-square test was used to compare abnormal findings. P ≤ 0.05 was taken as statistically significant. MedCalc 16.4 version software was used for all statistical calculations. Results: Significant difference was noted in skin pH and TEWL, where P value came out to be

Aspergillosis is an uncommon fungal infection in which primary cutaneous sites are very rare. Most cases occur in immunocompromised patients and infection in immunocompetent patients, is extremely rare, but an increase in prevalence has been noted in last 20 years. A case of primary cutaneous aspergillosis (PCA) in a 40-year-old immunocompetent shopkeeper resident of Jaipur Rajasthan presenting with verrucous growth on the lower lip has been reported in this case study.

Context: Recently, there has been an increase in the number of chronic, recurrent, and recalcitrant dermatophytosis. Many factors implicated are barrier defects, aberrant host immune response, application of steroids or other irrational combination creams, transmission within family, occlusive clothing, poor hygienic conditions, poor compliance, drug resistance and virulence of the infecting strain. Transepidermal water loss (TEWL) is an important index in accessing the barrier function of skin. Aim: To ascertain the role of TEWL from the lesional skin and its effect on the cure rate and relapse in patients of tinea cruris. Materials and Method: A hospital based prospective comparative study was conducted for 1 year. A total of 200 patients of tinea cruris diagnosed clinically and by KOH examination, were included in the study. TEWL was calculated using Tewameter TM300 open chamber probe of Courage and Khazaka, Cologne, Germany. Patients were classified according to the TEWL values into Group A (patients with abnormal TEWL) and Group B (normal TEWL). Both groups were given oral itraconazole and antihistamines for 4 weeks. The cure rates and recurrence rates of both the groups were analyzed and compared. Results: In the Group A, i.e., patients of tinea cruris with abnormal TEWL, only 28% of the patients showed clinical improvement at the end of 1 month. Out of those cured, 78.57% of the cases showed recurrence after 2 months of completion of therapy. In Group B, i.e., patients of tinea cruris with normal TEWL, 69% (n = 69) of the patients showed clinical improvement at the end of 1 month. Out of those cured, only 21.74% of the cases (n = 15) showed recurrence. Conclusion: The cases of tinea cruris with abnormal TEWL show significant decrease in cure rates and significant relapse rates among those initially cured.

In the beginning of the COVID-19 pandemic when we were still getting used to the rising cases every day and limited resources to deal them with, the focus was to get a hold of the situation as quickly as possible. Seven months into the pandemic, the cases are still on the rise but we have gathered some knowledge through the researches getting published every day, most of which are focused on the involvement of respiratory system, cardiovascular system, central nervous system, and gastrointestinal system. Dermatological manifestations have not been given their due importance. Lately, many patients have started presenting with dermatological manifestation sometimes preceding or sometimes during COVID-19 infection with or without involvement of other systems. This may be beneficial to clinicians all over the world, to determine potential dermatological signs in COVID-19 and also help in earlier suspection of the COVID-19 infection. Many cutaneous adverse drug reactions (ADR) to drugs advocated in COVID-19 treatment are also being reported every day, which are discussed in this review.Here we attempt to review dermatological manifestations of COVID-19 infections and drug reactions by the drugs advocated for its treatment and an understanding in its path mechanisms reported thus far. This will help clinicians to get an insight into what to expect and when to expect in terms of dermatological manifestation of COVID-19 and its drugs.

Context: Amyloidosis is group of rare diseases that are characterized by extracellular deposition of abnormal amyloid proteins either involving multiple organ systems (systemic amyloidosis) or restricted to a single-tissue site, such as skin (localized amyloidosis). In primary cutaneous amyloidosis, there is deposition of amyloid in apparently normal skin. The hyperpigmentation in all the lesions of primary cutaneous macular amyloidosis gives us an insight of a possibility of a connection between amyloid fibrils and melanogenesis. Aims: To compare the melanin content from the lesional skin of upper back and surrounding non-lesional skin of macular amyloidosis. Settings and Design: A hospital based, cross-sectional study conducted over a period of 6 months. Methods and Materials: Forty-two patients (30 females and 12 males) clinically and histopathologically diagnosed as macular amyloidosis were enrolled in the study. A Mexameter MX18 was used to measure the melanin index of the lesions of Macular amyloidosis over upper back and non-affected similar areas (control). Results: The melanin index of the lesional skin of female patients ranged from 552 to 823 (mean = 705.1). The melanin index of the lesional skin of male patients ranged from 621 to 792 (mean = 697.41). In the non-affected surrounding skin of females, the mean melanin index was 357.66, whereas in males, the melanin index of the surrounding normal skin was 296.75. The P value came out to be significant, that is
