Primarily personal sampling, which comprises potential or actual dermal exposure, provides a valuable contribution to the evaluation of various routes of exposure and thereby helps to comprehensively and correctly describe exposure situations in the workplace.<\/p>\n<p>Further information can be found <a href=\"https:\/\/www.ipasum.med.fau.de\/forschung\/arbeitsmedizinische-toxikologie\/dermales-belastungsmonitoring\/\">here<\/a><\/p>\n<p>Contact: <span class=\"fau-person person liste-person\"><span itemscope itemtype=\"http:\/\/schema.org\/Person\"><a href=\"https:\/\/www.ipasum.med.fau.de\/person\/anja-schaeferhenrich\/\"><span itemprop=\"name\"><span itemprop=\"honorificPrefix\">Dr. rer. nat.<\/span> <span class=\"fullname\"><span itemprop=\"givenName\">Anja<\/span> <span itemprop=\"familyName\">Sch\u00e4ferhenrich<\/span><\/span><\/span><\/a><\/span><\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"accordion-group\">\n<h2 class=\"accordion-heading\"><button class=\"accordion-toggle\" data-toggle=\"collapse\"  href=\"#collapse_1\" aria-expanded=\"false\" aria-controls=\"collapse_1\" id=\"collapse_button_1\"> Glove study <\/button><\/h2>\n<div id=\"collapse_1\" class=\"accordion-body\" aria-labelledby=\"collapse_button_1\">\n<div class=\"accordion-inner clearfix\">\n<p><strong>\u201eSkin hazards from wearing gloves which are impervious to fluids\u201c<\/strong><\/p>\n<p><strong>Objective:<\/strong><\/p>\n<p>Wearing gloves which are impervious to fluids is considered \u201chumid work\u201d (TRGS\u00a0401) and, according to ArbMedVV, occupational medical care is required for workers engaging in at least four hours of humid work per day, even if there is no scientific evidence to date to suggest that working with such gloves is significantly damaging to the skin when the workers\u2019 hands are clean and in the absence of hazardous substances (Ochsmann et al. 2006). This study will examine whether workers who regularly work more than 4\u00a0hours per day wearing liquid-tight gloves suffer more frequently from skin changes on the hands or whether their skin changes are more severe than workers who do not wear gloves.<\/p>\n<p><strong>Materials and methods:<\/strong><\/p>\n<p>A collective of workers from the semiconductor industry \u2013 workers from the clean room who wear liquid-tight gloves more than 4\u00a0hours per day as well as administrative workers to serve as a control group \u2013 were included and investigated as part of the study. Alongside glove-wearing behaviour, non-occupational risk factors for hand eczema (gender, smoking, atopy, etc.) were systematically surveyed as part of a standardised interview. The dermatological findings of the hands were measured using the quantitative skin score HEROS; physiological skin parameters for the measurement of subclinical skin damage were investigated via transepidermal water loss (TEWL) and corneometry. Furthermore, polarisation spectroscopy was used as a new investigative instrument for occupational medicine in the field.<\/p>\n<p><strong>Results:<\/strong><\/p>\n<p>When using the HEROS score, clinical dermatological findings of the hands showed no significant difference when comparing the collectives \u201cglove wearers\u201d vs. \u201ccontrols\u201d. Transepidermal water loss (TEWL), however, was significantly increased for \u201cglove wearers\u201d. In any case, these changes were no longer detectable about 30 to 40\u00a0minutes after glove removal and did not indicate a permanently affected skin barrier. In the multiple linear regression, the duration of activity seemed to be a significant influential factor for the magnitude of TEWL for part of the study collective. \u201cGlove wearers\u201d reported skin diseases on the hands more frequently since beginning work in the clean room. No significant difference in the anamnesis could be found between the collectives regarding relevant skin changes to the hands, such as from hand eczema or signs of atopy, ruling out the possibility of selection bias.<\/p>\n<p><strong>Conclusion:<br \/>\n<\/strong><\/p>\n<p>Our investigations showed that wearing liquid-tight gloves for more than 4\u00a0hours per day with clean hands and in the absence of hazardous substances shows no indication of serious effects on the condition of the skin, such that it must be discussed whether clean-room workers require supplementary, symptom-related preventive care in addition to a concrete (clean room-related) skin-protection policy or whether the mandatory preventive care prescribed by ArbMedVV should continue be carried out at fixed intervals.<\/p>\n<p><strong>References:<\/strong><\/p>\n<p>Weistenh\u00f6fer W, Wacker M, Bernet F, Uter W, Drexler H.

Based on current scientific knowledge, an additional UV exposure of 40% leads to double the risk (RR = 2) of squamous cell carcinomas. Squamous cell carcinomas and multiple actinic keratosis of the skin may be recognised and compensated as occupational diseases per No.\u00a05103 of the appendix to the German Ordinance on Occupational Diseases, if the location of the tumour required an additional occupational UV exposure of at least 40%. Occupational and non-occupational solar UV exposure must therefore be retrospectively and quantitatively estimated and contextualised in order to determine whether a suspected case of an occupational disease can be reported. The Online UV Anamnesis Tool makes this possible in a reasonable amount of time. Examinations on its application in field studies and validity tests have yielded good results.<\/p>\n<p><strong>Literatur<\/strong><\/p>\n<p>Weistenh\u00f6fer W, Hiller J, Drexler H, Kiesel J.
