Summary
Contact vitiligo, often caused by cosmetic products like bindis, affects mostly women. Early treatment leads to better outcomes for this skin condition.
Area of Science:
- Dermatology
- Contact Dermatitis
Background:
- Contact vitiligo is a depigmentation disorder triggered by external agents.
- Identifying specific etiological agents is crucial for effective management.
Purpose of the Study:
- To identify the etiological agents responsible for contact vitiligo in a cohort of patients.
- To evaluate treatment response based on disease duration and causative factors.
Main Methods:
- Clinical history, lesion distribution, and patch testing were used to identify causative agents in 50 patients.
- Patients received advice to avoid triggers, PUVASOL therapy, and topical steroids.
Main Results:
- Sticking bindis were the primary cause in 48% of cases; combined with other products in 28%.
- Patch testing showed positive reactions in 36% of patients.
- Treatment response was significantly better in patients with shorter disease duration.
Conclusions:
- Bindis are a common cause of contact vitiligo, often in conjunction with other cosmetic products.
- Early intervention and avoidance of triggers are key for successful treatment outcomes in contact vitiligo.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
