Journal of drugs in dermatology : JDD
|March 4, 2026
概括
由指甲产品引起的伪病性指甲缩 (PPND) 模仿了牛皮. 通过贴片检测识别像烯酸盐这样的过敏原有助于诊断和治疗,在几个月内改善了指甲的外观.
科学领域:
- 皮肤病学和指甲疾病
- 过敏接触性皮肤炎 (ACD)
- 化品产品的安全性
背景情况:
- 伪牛皮性指甲发 (PPND) 是一种模仿牛皮性指甲变化的过敏接触性皮肤炎 (ACD).
- 使用指甲产品是PPND的常见触发因素,导致诊断挑战和延迟.
- PPND的临床表现往往与牛皮形缩症重叠,缺乏诸如油滴或鱼斑等病理学征兆.
研究的目的:
- 为了识别由类似于伪银病变的化指甲产品引起的缩性指甲变化.
- 为PPND提供诊断和管理策略.
- 为了区分指甲的ACD与牛皮形缩症.
主要方法:
- 对指甲产品诱导的ACD临床文献的综述.
- 专注于识别常见的过敏原,特别是烯酸盐 (例如,三乙烯糖醇二甲酸盐,基乙烯酸盐,基乙烯甲酸盐).
- 重点是诊断方法,包括彻底的病史和专业的贴片检测.
主要成果:
- 三乙烯基醇二甲酸盐,基乙烯酸盐和基乙烯基甲酸盐是PPND中经常被识别的过敏原.
- 针对烯酸盐的专业补丁测试对于准确的诊断至关重要,因为它们通常不在标准面板中.
- 停止使用违规指甲产品会在大约3.5个月内显著改善指甲的外观.
结论:
- 准确的PPND诊断需要通过仔细的病史和专业的贴片检测来区分它和牛皮形形.
- 识别和避免引起指甲产品过敏原是一种有效的管理策略.
- 有效管理PPND可以减少对通常用于牛皮的全身治疗的需求.

Accessory Structures of the Skin: Nails
3.8K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
546
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Nephrotic Syndrome I : Introduction
787
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Accessory Structures of the Skin: Sebaceous Glands
4.9K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...
