Skin Cancer01:30

Skin Cancer

6.5K
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...

Changes in Skin Color: Clinical Perspectives

4.0K
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...

Pigmentation01:19

Pigmentation

4.8K
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...

Skin Diseases and Disorders

6.0K
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

8.5K
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...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

275
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Summary
This summary is machine-generated.

Combination therapies, especially with narrowband UV-B, show higher efficacy for vitiligo repigmentation than monotherapies. However, these combined treatments are linked to increased adverse effects, necessitating careful consideration of risks and benefits.

Area of Science:

  • Dermatology
  • Phototherapy
  • Pharmacology

Background:

  • Vitiligo is a chronic skin condition characterized by depigmentation.
  • Effective treatment strategies are sought to improve repigmentation and minimize adverse events.

Purpose of the Study:

  • To evaluate the efficacy and safety of different interventions for vitiligo treatment.
  • To compare combination therapies versus monotherapies for vitiligo repigmentation.

Main Methods:

  • Review of evidence on various vitiligo treatment interventions.
  • Assessment of reported repigmentation rates and adverse events associated with different therapies.

Main Results:

  • Combination therapies, particularly with narrowband UV-B, demonstrated superior repigmentation compared to monotherapies.
  • Limited evidence supports UV-A or UV-B monotherapy alone for vitiligo.
  • Moderate evidence supports combination therapies (UV-A/UV-B with psoralens, corticosteroids, vitamin D analogues, fluorouracil, azathioprine, oral prednisolone) for improved outcomes.
  • Combination therapies were associated with a higher incidence of adverse effects.

Conclusions:

  • Combination therapies offer enhanced efficacy for vitiligo repigmentation.
  • The increased risk of adverse effects with combination therapies requires careful patient selection and monitoring.
