The correlation between skin barrier function and transepidermal water loss (TEWL) was evaluated in dogs. Stratum corneum (SC) of 10 healthy dogs was removed by tape stripping (TS), which decreased the corneal layer to allow for permeation of fluorescent dye into skin. TEWL of damaged skin was measured with the closed-chamber-type TEWL analyzer, CC-01. The frequency of TS was directly related t...

Transepidermal water loss (TEWL) is a simple noninvasive measurement of inside-out skin barrier function. The goal of this research was to establish normal values for TEWL in early life using data gathered from the Cork BASELINE Birth Cohort Study. TEWL was recorded in a standardized fashion using a well-validated open-chamber system. A mean of three readings was recorded from 1,036 neonates (3...

NewDiagnosticMethod for LesionsWith TransepidermalMelanocyticMigration Transepidermal melanocytic migration (TEM) is a histological feature that is frequently observed in malignant melanoma but may also occur in nevi (eg, Spitz nevi, acral nevi). Pagetoid TEM is considered a key indicator of malignant disease.Werefer toanunusual case reportbyKerl et al1 in ayoung female patient. Elevenmelanomas...

The development of the integumentary system is a series of events that starts in utero and continues throughout life. Although at birth, skin in full-term infants is anatomically mature, functional maturity develops during the first year of life. Pediatric skin transitions again with the onset of puberty. At each stage, there are changes in transepidermal water loss, skin hydration, and skin ac...

Background Strongyloides stercoralis, a geohelminth which affects humans, has a cosmopolitan distribution in the tropical and subtropical areas but is sporadic in temperate countries like Romania. Acquired perforating disorders are a group of uncommon skin conditions characterized by transepidermal extrusion of dermal components, usually occurring in patients with chronic renal failure and/or d...

Elastosis perforans serpiginosa is a rare, primary perforating dermatosis, frequently associated with certain genetic diseases and characterized by the transepidermal extrusion of elastic fibers. The present case report describes this dermatosis in a 19-year old female patient with Down's syndrome, who presented with asymptomatic erythematous, keratotic papules in an arciform pattern, located o...
