Pigmentation

Pigmentation

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...

Changes in Skin Color: Clinical Perspectives

Changes 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.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer

Skin 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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Role of Skin in Vitamin D Synthesis

Role 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).

Skin Diseases and Disorders

Skin 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...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Summary

Cigarette smoking harms the skin, impacting various dermatologic conditions. Understanding these effects can guide smoking cessation or new nicotine-based treatments for skin diseases.

Area of Science:

Dermatology
Toxicology
Pharmacology

Background:

Cigarette smoking is linked to widespread health issues, including the integumentary system.
Tobacco use presents numerous dermatologic hazards.
Distinguishing between tobacco smoke and nicotine effects on skin is crucial.

Purpose of the Study:

To review the dermatologic hazards associated with tobacco use.
To differentiate the effects of tobacco smoke from pure nicotine on skin.
To explore the impact of smoking on chronic dermatoses.

Main Methods:

Literature review of studies on smoking and skin health.
Analysis of nicotinic acetylcholine receptor expression in skin cells.
Examination of the relationship between smoking and various dermatologic conditions.

Main Results:

Skin cells possess nicotinic acetylcholine receptors, including the α7 subtype.
Smoking can negatively or positively influence many chronic dermatoses.
Understanding these associations can inform treatment strategies.

Conclusions:

Smoking cessation can improve conditions positively associated with tobacco use.
Nicotinergic agonists may offer disease-specific treatments for dermatoses inversely correlated with smoking.
Further research into the specific mechanisms of nicotine on skin is warranted.
