Abstract:
As a surrogate measure of skin barrier dysfunction, we sought to determine differences in transepidermal water loss (TEWL) among ichthyosis subtypes and correlate TEWL with clinical severity. Subjects with Netherton syndrome had the highest TEWL values (increased water loss), while TEWL values were lowest in subjects with epidermolytic ichthyosis. TEWL correlated with severity only in lamellar ichthyosis and age was inversely correlated with TEWL (rs = -.213, P = .02). TEWL is an objective measure that complements disease severity in ichthyosis and may be used as an adjuvant to monitor treatment response.

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
