Mutations01:35

Mutations

44.7K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Skin Cancer01:30

Skin Cancer

6.2K
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...

Pigmentation01:19

Pigmentation

4.6K
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

8.2K
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...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Area of Science:

  • Dermatology
  • Photobiology

Background:

  • Photosensitive atopic dermatitis (AD) is a rare condition often unfamiliar to physicians, leading to misdiagnosis.
  • This photosensitivity can significantly impair patients' quality of life, necessitating strict sun avoidance.

Observation:

  • A case of photosensitive AD exacerbated by ultraviolet B (UVB) exposure is presented.
  • Diagnosis was confirmed through phototesting, identifying UVB as the trigger.
  • Histopathologic findings in photosensitive AD are typically nonspecific.

Findings:

  • Phototesting is essential for diagnosing photosensitive AD and determining UV wavelength sensitivity.
  • A comprehensive history and physical examination are vital for identifying potential cases.
  • Treatment with narrowband UVB (NB-UVB) hardening, alongside immunosuppression, was initiated post-diagnosis.

Implications:

  • Accurate diagnosis of photosensitive AD is key to implementing effective treatments.
  • Increased physician awareness and utilization of photodiagnostic tools are needed.
  • Further research into photosensitive AD is warranted due to limited literature and diagnostic challenges.
