Summary
Post-inflammatory hyperpigmentation (PIH) is a common skin condition. Understanding its cellular and molecular mechanisms is key to developing new targeted treatments for this acquired hyperpigmentation disorder.
Area of Science:
- Dermatology
- Pathophysiology
- Hyperpigmentation Disorders
Background:
- Post-inflammatory hyperpigmentation (PIH) is a frequent disorder of acquired hyperpigmentation.
- It arises after cutaneous inflammation from diverse triggers like autoimmune conditions, iatrogenic causes, and injuries.
- Increased melanin in the epidermis and dermis characterizes PIH, but underlying mechanisms require further elucidation.
Purpose of the Study:
- To review current evidence on the pathophysiology of post-inflammatory hyperpigmentation.
- To explore the cellular and molecular mechanisms driving PIH development.
- To identify potential targets for novel therapeutic strategies.
Main Methods:
- Literature review of existing research on PIH.
- Analysis of cellular and molecular pathways involved in hyperpigmentation.
- Synthesis of current understanding of PIH pathogenesis.
Main Results:
- PIH results from increased melanin production and altered distribution.
- Various inflammatory stimuli contribute to the development of PIH.
- Specific cellular and molecular pathways are implicated but not fully understood.
Conclusions:
- Further research into PIH pathophysiology is essential.
- Understanding cellular and molecular mechanisms offers a promising route for targeted therapies.
- Novel treatments for PIH can be developed by targeting these mechanisms.

01:14Changes in Skin Color: Clinical Perspectives
2.5K
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.

01:19Pigmentation
3.1K
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...

01:22Photoreceptors and Visual Pathways
6.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:28Inflammatory Response
9.6K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

5.9K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
