Contact dermatitis is one of the common work-related dermatoses. Among bricklayers, cement can cause both allergic contact dermatitis and primary contact irritative dermatitis. The personal protective equipment (rubber gloves) may favor the development of allergic contact dermatitis.
A retrospective analysis of patch tests. Patients were separated into two groups: 1) bricklayers and 2) non-bricklayers.
Of the 525 patch tests analyzed, 466 (90%) were from non-bricklayers and 53 (10%) from bricklayers. The hands were affected in 38 (61%) of them. 13 patients (24%) had irritative contact dermatitis and 40 (76%) had allergic contact dermatitis. The group of construction workers had a high frequency of sensitization to cement, and 29 (54.7%) had sensitization to rubber vulcanizing agents. 23 patients (43.4%) had sensitization to both cement and rubber.
Among the bricklayers the presence of allergic contact dermatitis to rubber and cement in the same patient is common and demonstrates the importance of the patch test.
接触性皮炎是常见的职业性皮肤病之一。在砌砖工人中,水泥可导致过敏性接触性皮炎和原发性接触刺激性皮炎。个人防护装备(橡胶手套)可能会促使过敏性接触性皮炎的发生。
1)评估2005年1月至2009年12月期间建筑工人中过敏性接触性皮炎的发生率;2)确定研究组中的主要致敏剂;3)将建筑工人的数据与一组非建筑工人患者的数据进行比较。
对斑贴试验进行回顾性分析。患者分为两组:1)砌砖工人和2)非砌砖工人。
在分析的525次斑贴试验中,466次(90%)来自非砌砖工人,53次(10%)来自砌砖工人。其中38次(61%)手部受累。13名患者(24%)患有刺激性接触性皮炎,40名患者(76%)患有过敏性接触性皮炎。建筑工人组对水泥的致敏频率较高,29名(54.7%)对橡胶硫化剂致敏。23名患者(43.4%)对水泥和橡胶均致敏。
在砌砖工人中,同一患者对橡胶和水泥发生过敏性接触性皮炎很常见,这表明了斑贴试验的重要性。
