Pigmentation01:19

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 Perspectives01:14

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...
Drug Toxicity: Dose-Dependent Reactions01:24

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
Skin Cancer01:30

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...
Desensitization and Tachyphylaxis01:20

Desensitization and Tachyphylaxis

Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
Several...
Role of Skin in Vitamin D Synthesis01:23

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).

Summary
This summary is machine-generated.

Excessive tanning, characterized by impulsive and repetitive behavior despite negative consequences, is increasingly recognized as a behavioral addiction. Further research is needed to understand its psychopathology and neurobiology.

Area of Science:

  • Behavioral addiction research
  • Psychiatric disorder classification
  • Dermatology

Context:

  • Socially valued tanning behaviors can develop addictive patterns.
  • Excessive tanning is defined by impulsivity, repetition, and personal distress.
  • Dermatologists observe addictive tanning behaviors even after melanoma diagnosis.

Purpose:

  • Synthesize existing literature on excessive tanning and addiction.
  • Investigate prevalence, clinical features, etiology, and treatment.
  • Explore associations between tanning behaviors and addiction models.

Summary:

  • Excessive tanning exhibits craving-like symptoms, loss of control, and continued behavior despite risks.
  • Diagnostic criteria for tanning addiction are being developed, though not yet in DSM or ICD.
  • Potential links exist with Addiction, Obsessive-Compulsive Disorder, and Body Dysmorphic Disorder.

Impact:

  • Excessive tanning shares characteristics with classic addictive disorders, suggesting inclusion in behavioral addiction spectrum.
  • Further controlled studies on psychopathology, neurobiology, and management are crucial.
  • Understanding tanning addiction can inform prevention and treatment strategies.
