Transepidermal water loss in erythrodermic patients of various aetiologies.

Background/purpose: Despite its severity not much work has been done to explore the barrier function in patients with erythroderma. This study compares TEWL between skin of healthy subjects and erythrodermic patients of various aetiologies and at different sites. We also assess TEWL between patients with acute and chronic erythroderma.
