    Description / Table of Contents: Zusammenfassung Eine neue Routinetestmethode für die qualitative analyse des Hautoberflächenfetts am Menschen wird vorgestellt. Diese Methode verbindet die Vereinfachung der Probenentahme, durch direkten Kontakt eines Raughglas-Plättchens und dem Hautfett, mit einer genauen dünnschichtchromatographischen Analyse der fünf Grundparameter (Cholesterol, Freie Fettsäuren, Triglyceride, Wachsesters, Squalen) ohne Vorbehandlung der Proben. Dieses Verfahren kann für jede Körperregion angewandt werden.
    Notes: Summary A new routine testing procedure of qualitative analysis of skin surface lipids in man is proposed. This method combines the easiness of sampling, by direct contact between ground glass plates and skin fat, with accurate thin layer chromatographic analysis of the five basic parameters (cholesterol, free fatty acids, triglycerides, wax esters, squalene) without any treatment of the samples. Such procedure can be applied to any region of the body.

    Notes: Summary This paper describes an original in vivo device to investigate and quantify cutaneous resorption of sebum. Such a phenomenon was explored using a photometric determination of residual skin surface lipids at different times following initial deposits of known amounts of artificial sebum on demarcated areas. The technique was carried out on seven healthy subjects. The chosen area was the anterior aspect of the forearm, owing to the very low sebum production of this site, less than the sensitivity of the measuring instrument. The kinetics of absorption of applied sebum turned out to be hyperbolic-like and well correlated with experimental results (r=0.992), allowing a mathematical determination of the initial velocity of penetration of sebum into the skin, reaching 20 μg/cm2 · min for a standard program including a mean initial deposit of 116 μg/cm2. This kinetics actually does not fit with a true percutaneous absorption of lipids but is compatible with that of absorption into the stratum corneum. It conveys the faster absorption of the latter for sebum, a well-known but not so far quantified property of stratum corneum. The model here described is not at once transposable to skin areas with high sebum production since, quite obviously in such zones, the stratum corneum is permanently saturated with skin surface lipids. Therefore, the conclusions of this work cannot be correlated with the regreasing parameters studied so far on the forehead, but they provide interesting data about the evolution of sebum following its output onto the skin surface and therefore a better understanding of sebaceous physiology.

    Isolation and identification of human hair ceramides (1995)

    Notes: The analysis of the lipids extracted from human hair by silica-gel-column liquid chromatography permitted an isolation of the fraction enriched in free ceramides. These were identified by GC/MS and are related to ceramide classes 2 and 5 in which the long-chain base was predominantly sphinganine. This differs from that observed in the free ceramides found within the stratum corenum.

    Notes: Il existe trois méthodes permettant de mesurer l'excrétion sébacée chez l'homme. Ces méthodes ne sont pas équivalentes sur le plan de la précision et de leur utilisation routinière. Une application de la méthode de Schaefer et Kuhn-Bussius est proposée, permettant une détermination rapide et precise des taux des lipides de surface chez l'homme. Une expérimentation, avec cette méthode, chez trente-deux personnes, permet de préciser le mécanisme du prélèvement ainsi que la définition quantitative des types de peau.〈section xml:id="abs1-2"〉〈title type="main"〉SummaryThree main methods to measure quantitatively surface lipids in man have been used. A comparison of the information they produce and their routine practicabilities are given.Adaptation and standardization of the Schaeffer and Kuhn-Bussius method, using a photoelectric absorptiometer and ground glass plates are described.This procedure, applied to thirty-two adults, demonstrated the quantitative nature of the sampling mechanism. A mathematical approach gives the precise definition of the casual-level. This procedure shows that casual-level values appear to be correlated with skin types.

    The hair eclipse phenomenon: sharpening the focus on the hair cycle chronobiology (2003)

    Notes: Chronobiology governing the hair cycle is a fascinating and complex process. Both the hair growth cycle and the hair shaft growth are coordinated and depend on the interplay of different biological signals and various exogenous stimuli. A latency period may occur between hair shedding (teloptosis, exogen phase) and the early emergence of the next anagen VI stage. This lag time referred to on the hair eclipse phenomenon likely depends on the influence of a series of distinct synchronizers, and does not represent per se a peculiar hair cycle phase. It is the result of some dysregulations of the hair cycling, involving early teloptosis, delayed anagen I initiation or stunted hair growth at any stage between the anagen I and anagen V phases. As such, the hair eclipse phenomenon may be an erratic process occurring in physiopathological conditions affecting hair follicles singly or in focal to generalized patterns. It may be more frequent when it follows synchronized teloptosis occurring in telogen effluvium (newborn alopecia, post-partum alopecia, seasonal alopecia and alopecia areata). It may also be prominent when microinflammation is abutted on the permanent portion of the hair follicle as in dandruff, seborrhoeic dermatitis, androgenic alopecia and photoageing baldness. Local synchronizers such as growth factors and other mediators may eventually be lacking or involved in the hair eclipse phenomenon. Their identification and characterization might drive new corrective or preventive applications.

    Effect of residence time on the efficacy of antidandruff shampoos (2003)

    Notes: Dandruff is known to be controlled by fungistatic shampoos active against Malassezia spp. These products also remove the loosely attached scales. This study was performed to assess the effect of a 5-min residence time on the efficacy of antidandruff shampoos. Two commercially available shampoos were used in two groups of 21 panelists with severe dandruff. They contained either 1% ketoconazole or 1% piroctone olamine. In each group, intraindividual comparisons were made by a split-scalp design between the effect of a 5-min residence time versus no residence time. Both shampoos induced significant reductions in scaliness and yeast colonization. The beneficial effects were obvious immediately after one single shampooing and 3 days later as well. The improvement was greater with a 5-min residence time. The piroctone olamine treatment benefited more than the ketoconazole treatment from the extension of shampoo-exposure time. In conclusion, the benefit of a residence time in treating dandruff is documented. The level of improvement in efficacy may vary according to the nature of the shampoo.

    Notes: Background In the Allergic Rhinitis and its Impact on Asthma (ARIA) classification, intermittent and persistent rhinitis were proposed to replace seasonal and perennial allergic rhinitis (AR).Aim To better understand the ARIA classification of rhinitis.Methods A cross-sectional study was carried out in 591 patients consulting ENT or allergy specialists for AR and 502 control subjects. The diagnosis of AR was based on a score for allergic rhinitis (SFAR) 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:09547894:CEA2274:ges" location="ges.gif"/〉7. Patients were classified according to the four ARIA classes (mild intermittent, mild persistent, moderate/severe intermittent and moderate/severe persistent). Allergen sensitization (skin prick tests (SPTs) or specific IgE) and co-morbidities were examined according to the ARIA classes.Results Ten percent of patients had mild intermittent rhinitis, 14% mild persistent rhinitis, 17% moderate/severe intermittent rhinitis and 59% moderate/severe persistent rhinitis. Most patients with intermittent rhinitis had a pollen sensitivity, but 5% had a single house dust mite (HDM) sensitization. Over 50% of patients with persistent rhinitis were allergic to pollens or HDM. Asthma was present in 24% of rhinitis patients and in only 2% of the control population (P〈0.0001). Patients with moderate/severe persistent rhinitis had the highest asthma prevalence (33%).Discussion Intermittent and persistent rhinitis are not synonymous of seasonal and perennial rhinitis. Most patients consulting specialists have severe rhinitis. Asthma prevalence increases with duration and severity of rhinitis supporting the ARIA major recommendation that patients with persistent rhinitis should be evaluated for asthma.
