Cutaneous Adverse Drug Reactions (CADRs) to COVID19 Vaccines: A Case Series.

Viral vector vaccines (Covishield) and inactivated vaccines (Covaxin) are now being administered worldwide to reduce the impact of life-threatening corona virus disease 19 (COVID-19). Various cutaneous adverse drug reactions (CADRs) have been reported following COVID-19 vaccination. Here, we are reporting series of CADRs following COVID-19 vaccination.

Melanogenesis Markers Expression in Premature Graying of Hair: A Cross-Sectional Study.

Background: Studies on mice and aging human hair follicles provide compelling evidence that graying of hair results from premature differentiation of melanocyte stem cells in the niche/bulge.

Objective: The aim of this study was to analyze whether differentiation of melanocyte stem cells is responsible for premature graying of hair (PGH).

Methods: Twenty-five patients with PGH (n = 25) attending the dermatology department were recruited.

Non-venereal genital dermatoses and their impact on quality of life-A cross-sectional study.

Background: Lesions on the external genitalia could be venereal or non-venereal. Non-venereal genital dermatoses are common and may cause considerable anxiety to patients, particularly if noticed after sexual intercourse. However, this aspect has not been studied much till now.

Association of Acanthosis Nigricans and Insulin Resistance in Indian Children and Youth - A HOMA2-IR Based Cross-Sectional Study.

Introduction: The American Diabetes Association includes acanthosis nigricans (AN) as an indicator of diabetes mellitus risk in overweight youth entering puberty. Some argue that AN is not an independent predictor of insulin resistance (IR), when body mass index (BMI) is controlled for. There is a paucity of studies on the association of AN and IR among children and young adults from India.

Patch Testing in Allergic Contact Dermatitis over the Lower Extremities.

Background: There is an increased incidence of allergic contact dermatitis (ACD) over the lower extremities due to over-the-counter topical preparations, occupational risk, and usage of several chemicals in the manufacture of designer footwear.

Aims And Objectives: The aim of the study was to identify the common allergens and polysensitization pattern involved in ACD over the lower extremities.

Materials And Methods: It is a cross-sectional study, wherein a total of 80 patients were recruited over a period of 18 months.

Appearance of Verruca Over Linear Verrucous Epidermal Nevus - An Example of Locus Minoris Resistentiae: A Report of Three Cases.

Locus minoris resistentiae (LMR) is a site of the body that offers lesser resistance than the rest of the body to the onset of disease. It can be congenital or acquired. Areas of cutaneous mosaicism such as epidermal nevi can act as congenital LMR, leading to the development of inflammatory skin conditions or skin tumors on these.

Antihypertensives in dermatology Part II - Cutaneous adverse reactions to antihypertensives.

Antihypertensive drugs are prescribed frequently and can cause cutaneous adverse reactions. The exact incidence and frequency of these reactions are unknown. Multiple antihypertensive drug consumption has contributed to a substantial increase in the number of cutaneous adverse reactions to them.

Antihypertensives in dermatology Part I - Uses of antihypertensives in dermatology.

Hypertension is a global health problem. Antihypertensives are the mainstay of treatment for hypertension. Some of them were accidentally found to be useful in alopecias and infantile hemangiomas and have now become standard treatment for these conditions as well.
