概括
患有粉红的个体对UVA和UVB辐射都表现出皮肤敏感度增加. 建议尽量减少阳光照射,以防止粉红发作.
科学领域:
- 皮肤病学 皮肤病学
- 摄影生物学 摄影生物学
- 皮肤健康 皮肤健康
背景情况:
- 红是一种常见的慢性炎症性皮肤疾病,影响了脸部.
- 它呈现四种亚型:红斑性长性疹性疹 (ETR),纸性疹性疹 (PPR),花性疹 (PhR) 和眼部疹 (OR).
- 紫外线 (UV) 辐射是已知的粉红风险因素,但粉红患者与健康人群对UVA和UVB的敏感性差异尚不清楚.
研究的目的:
- 为了研究与健康对照组相比,粉红患者的皮肤对UVA和UVB辐射的敏感性差异.
- 探索紫外线敏感性和粉红疹亚型,年龄,皮肤类型,抗核抗体 (ANA) 和临床红疹评估 (CEA) 尺度之间的潜在相关性.
主要方法:
- 该研究包括70名粉红患者和100名健康对照.
- 用太阳紫外线模拟器 (SUV-2000) 来确定UVA和UVB的最小红斑剂量 (MED).
- 进行了群体间和粉红病亚型内的比较分析,并进行了相关性评估.
主要成果:
- 与健康对照组相比,粉红患者的MED-UVA和MED-UVB值明显较低 (分别p < 0.05和p ≤ 0.001).
- 在粉红病亚型 (ETR与PPR) 之间没有发现MED-UVA或MED-UVB的显著差异.
结论:
- 粉红患者对UVA和UVB辐射都表现出高度敏感,这是通过减少最小的红斑剂量来表明的.
- 建议减少阳光照射对于患有粉红的人来管理或预防病情恶化.

Pigmentation
3.8K
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...

Changes in Skin Color: Clinical Perspectives
3.6K
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.

Skin Cancer
5.2K
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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
81
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
