The stratum corneum (SC) serves as the skin barrier between the body and the environment. When the skin is contacted with an aqueous solution of the surfactant sodium dodecyl sulfate (SDS), a well-known model skin irritant, SDS penetrates into the skin and disrupts this barrier. It is well established, both in vitro and in vivo, that the SDS skin(More)
In order to visualize the effects of aqueous surfactant-humectant systems on the skin barrier, an in vitro two-photon fluorescence microscopy (TPM) study, including dual-channel visualization, was carried out. TPM is a non-invasive imaging technique based on two-photon induced nonlinear excitations of fluorophores, with the capability for deep-tissue(More)
We propose that skin electrical current measurements can be used in vitro to effectively rank aqueous solutions containing surfactants and humectants (the enhancer) contacting the skin, relative to a PBS aqueous solution (the control) contacting the skin, based on their ability to perturb the skin aqueous pores. Specifically, we develop an in vitro ranking(More)
Sodium cocoyl isethionate (SCI) is an important surfactant ingredient in mild, syndet (synthetic detergent) cleansing bars. In vitro and in vivo studies have demonstrated that SCI is mild and less damaging to the skin barrier than soaps and surfactants such as sodium dodecyl sulfate (SDS). We have recently shown that SDS forms small micelles in aqueous(More)
BACKGROUND Systemic sclerosis (SSc) is a rare connective tissue disorder of unknown aetiology. Pulmonary involvement contributes substantially to its morbidity and mortality. Treatment of pulmonary disease due to SSc remains unsatisfactory. We examined the effect of sequential six-month intravenous pulse therapy with cyclophosphamide (CYC) followed by(More)
Uterine sarcomas are rare and represent approximately 3.2% of all invasive uterine cancers. The annual incidence rate is less than two per 100,000 women. The median age at which uterine sarcoma diagnosed is 56 years. The most common histologic pattern is leiomyosarcoma (LMS) which originates from the myometrium or myometrial vessels. Uterine LMSs are(More)
Endobronchial capillary haemangioma is a very rare benign tumour in adults. The clinical presentation and management of adult capillary haemangiomas involving the tracheo-bronchial tree is not yet established. We present a case of an isolated capillary haemangioma of the left main bronchus detected during the evaluation of an adult male presented with(More)
