BACKGROUND: Skin lesions are among the most common complications of contact with sulfur mustard. OBJECTIVE: This study was aimed to measure skin water content and transepidermal water loss (TEWL) in patients with a history of sulfur mustard contact. METHODS: Three hundred ten male participants were included in this study: 87 (28.1%) sulfur mustard-exposed patients with current skin lesions (group 1), 71 (22.9%) sulfur mustard-exposed patients without skin lesions (group 2), 78 (25.2%) patients with dermatitis (group 3) and 74 (23.8%) normal controls (group 4) The water content and TEWL of skin was measured at four different locations of the body: forehead, suprasternal, palm and dorsum of hand. Nonparametric statistical tests (Kruskal-Wallis) were used to compare the four groups, and P < 0.05 was considered statistically significant. RESULTS: The mean age of participants were 44.0 +/- 6.7, 41.9 +/- 5.9, 43.8 +/- 9.3 and 44.8 +/- 8.9 years in groups 1 to 4, respectively (P = 0.146). Xerosis, post-lesional hyperpigmentation and lichenification were significantly more common in either sulfur mustard-exposed participants or non-exposed participants with dermatitis (P < 0.05). Skin hydration was higher in subjects with sulfur mustard contact than in non-injured participants (P < 0.05) in the dorsum and palm of hands and forehead. TEWL was significantly higher in participants only in suprasternal area and dorsum of hand. CONCLUSION: Contact with sulfur mustard agent can alter biophysical properties of the skin--especially the function of stratum corneum as a barrier to water loss-several years after exposure.
