Pigmentation01:19

Pigmentation

2.3K
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

1.9K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.0K
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,...

Summary
This summary is machine-generated.

Drug-induced pigmentation (DIP) is a common cause of acquired hyperpigmentation, affecting skin, nails, and hair. Treatment involves identifying the causative agent and may include laser therapy and photoprotection.

Area of Science:

  • Dermatology
  • Pharmacology

Background:

  • Drug-induced pigmentation (DIP) constitutes approximately 20% of acquired hyperpigmentation cases.
  • Over 50 medications, including antibiotics, antimalarials, and chemotherapeutics, are known to cause DIP.
  • DIP can manifest on the skin, mucosal surfaces, nails, and hair, with varied clinical presentations.

Purpose of the Study:

  • To review the unique characteristics of drug-induced pigmentation.
  • To examine inciting agents, their incidence, clinical presentation, and pathogenesis.
  • To discuss management strategies for drug-induced pigmentation.

Main Methods:

  • Review of literature on drug-induced pigmentation.
  • Analysis of clinical presentations and causative agents.
  • Examination of pathogenic mechanisms and treatment modalities.

Main Results:

  • DIP mechanisms include melanin accumulation, drug deposition, pigment synthesis, and iron deposition.
  • Photoprotection is crucial for preventing DIP exacerbation.
  • Laser treatments like picosecond alexandrite and Q-switched lasers show efficacy in clearing DIP.

Conclusions:

  • Accurate diagnosis of DIP requires a thorough physical examination and medication history.
  • Understanding the specific characteristics of each inciting agent is key for effective management.
  • Laser therapy and photoprotection are important components of DIP treatment.
