Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

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 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...

What is Climate?

What is Climate?

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

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).

The Skin Microbiota

The Skin Microbiota

The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

Area of Science:

Environmental Science
Dermatology
Public Health

Background:

Global climate change is accelerating due to natural and human factors, including greenhouse gas emissions and deforestation.
Observed changes include global warming, altered precipitation, and increased extreme weather events, posing significant societal challenges.
While impacts on social, economic, and health systems are widely studied, effects on skin physiology and diseases remain under-explored.

Purpose of the Study:

To review the multifaceted relationship between climate change and dermatology.
To highlight how environmental shifts influence the incidence and clinical presentation of skin diseases.
To underscore the skin's vulnerability as the body's primary interface with the environment.

Main Methods:

Literature review of existing studies on climate change and dermatology.
Analysis of environmental factors affecting skin health.
Examination of climate-driven changes in vector-borne and infectious skin diseases.

Main Results:

Climate change alters the geographical distribution of disease vectors, impacting infectious dermatoses like leishmaniasis and Lyme disease.
Warmer, humid conditions promote the proliferation of cutaneous bacteria and fungi.
Changes in climate patterns are linked to modifications in the occurrence and clinical manifestations of various skin conditions.

Conclusions:

The skin's susceptibility to environmental changes necessitates a deeper understanding of climate change's dermatological implications.
Further research is crucial to address the growing burden of climate-sensitive skin diseases.
Integrating climate change considerations into dermatological practice and public health strategies is essential.
