Development and Technology Assessment of the Analytical Performance of an Eight Position Dynamic Olfactometer

The European technical standard \u201cAir Quality\u2014Determination of Odour Concentration by Dynamic Olfactometry\u201d adopts dynamic olfactometry, a sensorial methodology based on the employment of a panel of human assessors, as the official methodology for the measurement of odour concentration in gas samples. The olfactometer is the device, useful to dilute the odor sample with neutral air, according to precise ratios and to present it to the panel for the analysis. The present paper describes the development of an Italian olfactometer, able to host eight assessors, designed to improve the instrumental performance of the devices actually present on the market, and to increase the accuracy and repeatability of the olfactometric measurement. In particular, in the paper the principal features of the instrumental device and the results of calibrations of dilution valves will be shown

The Role of Trichoscopy in Keratosis Follicularis Spinulosa Decalvans: Case Report and Review of the Literature

Keratosis follicularis spinulosa decalvans (KFSD) is a rare, X-linked, hereditary disorder of keratinization, characterized by skin involvement and progressive scarring alopecia of scalp, eyebrows, and eyelashes. The diagnosis is helped by the particular clinical features, but pathology is mandatory. Case Presentation: We described a case of a female patient referred to the outpatient's hair consultation of our department, in which we performed trichoscopy as a very useful tool for the diagnosis, followed by pathology that confirmed KFSD. Conclusion: In our article, we underlined the importance of trichoscopy for the diagnosis of this hair disease, with also a review of the literature on diagnosis and treatment
