Since there is currently no information on this condition in a small market like that in Portugal, the authors designed this descriptive cross-sectional study to characterize this syndrome in this particular context. Data was collected using a structured questionnaire in the community pharmacies chosen for the study. 333 questionnaires (n=333) were validated, and 46 % of the surveyed individuals described their skin as "sensitive". Responders were predominantly women, the face was the most frequently mentioned area of the body affected, and environmental factors and contact were reported as the main causes of sensitivity. A wide in responses to irritation and in the relationship with previous pathological conditions was also found. Thus, the social and demographic pattern found here agrees with patient-type profile previously reported for the sensitive skin syndrome.

Testing the Discriminative Capacity of Compartmental Modeling for the Analysis of the In-Vivo Epidermal Water Content Changes Following Topical Application under Occlusion / Pedro Contreiras Pinto in IFSCC MAGAZINE, Vol. 5, N° 2 (04-05-06/2002)

Langues : Anglais (eng) Tags : 'Skin  hydration'  'efficacy  testing'  'mthematical  modeling'  POST  'in-vivo  measurement'  evaporation  'dynamic  water  loss'  TEWL Index. décimale : 668.5 Parfums et cosmétiques Résumé : Mathematical modeling of cutaneous variables is an attratictive strategy to meet the compex nature of in-vivo skin, especially in the presence of an external stimulus such as a topical product. Despite the oversimplification implied, meeting the conceptualization of the model with the representative (physiological) variables is still a major difficulty, often impairing the model validity. Once achieved, however, its applicability will mostly depend on the demonstration of the accuracy and practicability of the model. In previous works, the authors developed a bi-compartmental model designed to dynamically describe the Trans-epidermal water loss(TEWL) curves obtained in-vivo from the Plastic Occlusion Stress Test (POST) methodology. Occlusion was performed in healthy human volunteers (n=10) occluded with either 10% glycerin in water solution or water alone. Desorption curves allowed to obtain kinetic parameters such as k(evap)(the water evaporation rate at skin surface), t1/2 evap(the evaporation half-life), and DWM (the dynamic water mass) allowing a detailed quantitative description of the hydration process. Results demonstrate that the proposed model is adequate to identify significant differences (p<0.05) between the curve profiles, revealing the different hydration mechanisms involved, and suggesting an interesting application potential for the substantiation and efficacy testing of cosmectics.
