概括
一个新的皮肤有效地减少后炎性超色素 (PIH) 后二氧化碳 (CO2) 微分激光重新表面化在患有较深色肤色的患者. 这种治疗可以改善PIH,而不会影响减少痕的结果.
科学领域:
- 皮肤病学 皮肤病学
- 审美医学是一种美学医学.
- 激光疗法是一种激光疗法.
背景情况:
- 缩性痕是一个常见的问题,微分二氧化碳 (CO2) 激光复苏是标准的治疗方法.
- 较深色的皮肤类型 (菲茨帕特里克III-V) 在CO2激光治疗后面临着炎症后多颜色化 (PIH) 的高风险,限制了其应用.
- 制定减轻PIH的策略对于在不同皮肤种群中成功治疗痕是至关重要的.
研究的目的:
- 评估一种新的治疗前和治疗后皮肤在分数CO2激光重新表面化后最大限度地减少PIH的有效性.
- 评估附加剥皮治疗对菲茨帕特里克皮肤类型III-V患者PIH发病率和严重性的影响.
- 分析二次结果,包括愈合时间和痕改善.
主要方法:
- 29名患有缩性痕的患者接受了二氧化碳激光再表面化.
- 一个研究小组 (n=15) 在激光复苏之前和之后接受了一种新的剥皮治疗.
- 炎症后超色素 (PIH) 用6周的炎症后超色素区域和严重性指数 (PIHASI) 量化;痕分级和愈合时间也被评估.
主要成果:
- 与对照组相比,接受剥皮治疗的组在6周的PIHASI中位数明显较低 (p=0.015).
- 剥皮和不剥皮组之间的重新上皮化时间相似 (6.4日与6.2日).
- 两组之间在痕改善方面没有发现显著差异,也没有报告任何不良事件.
结论:
- 这种新的皮肤剥离方法有效地降低了Fitzpatrick类型较高的皮肤类型的患者在二氧化碳激光再表面化后的PIH风险.
- 额外的剥皮治疗不会影响痕治疗的结果.
- 需要对更大的患者队伍进行进一步的研究,以确认这种方法的长期有效性.

Changes in Skin Color: Clinical Perspectives
2.2K
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...

Clinical Applications of Epidermal Stem Cells
2.8K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Pigmentation
2.7K
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...

Renewal of Skin Epidermal Stem Cells
2.6K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
