Abstract
The manufacture of counterfeit goods is one of the world’s largest underground businesses and is rapidly growing. Counterfeits can lead not only to the loss of profit for honest producers but also have a negative impact on consumers who pay excessive prices for poor quality goods that may result in health or safety problems. The perfume industry is constantly vulnerable to counterfeits, particularly in the fast developing market of “smell-alike” designer-inspired perfumes because these prompt the identification of the methods that classify their quality. In this paper, the application of proton nuclear magnetic resonance (1H NMR) spectroscopy is employed for the first time to authenticate perfumery products. The molecular composition of several types of authentic brand fragrances for women was compared with cheap inspired equivalents and fakes. Our approach offers the prospect of a fast and simple method for detecting counterfeit perfumes using 1H NMR spectroscopy.

Abstract
Purpose of review The main aims of fragrances are to create pleasing scents or to mask unpleasant odors. We hereby review their main exposure sources, presumed benefits, and unwanted effects, with special attention to allergic contact dermatitis (prevalence, regulatory environment, risk assessment methodology, and preventive measures). Recent findings Fragrances elicit positive emotions and presumably have therapeutic benefits related to stress reduction and memory enhancement. However, they also cause detrimental health or environmental effects including contact dermatitis (irritant and/or allergic), non-eczematous contact reactions, photosensitivity, photo-allergy, and immediate contact reactions, which can negatively impact the quality of life. Fragrances are the most frequent chemicals causing contact dermatitis. Their main sources are cosmetics, household products, industrial substances, food flavorings, oral hygiene products, and topical medications. It is difficult for sensitized patients to avoid contact with fragrances, due to their ubiquity and because manufacturers are not willing to volunteer information regarding fragrance ingredients. Summary The treatment of contact dermatitis relies on allergens avoidance which does not “cure” the disease (sensitization persists for life) but prevents disabling illness. The patient should understand that avoiding perfume means to avoid all scented goods and not just perfumes. Labeling fragrances is key in primary prevention (by giving the healthy individual the chance to make an informed choice to avoid risky substances), diagnosis (by helping the practitioner to plan and interpret patch tests), secondary prevention, and prognosis (by allowing the sensitized patient to follow the avoidance instructions). However, only 26 fragrances are mandatory to be declared in cosmetics. The vague labeling of other fragrance ingredients as “perfume” or “fragrance” hampers the diagnostic and preventive approaches. Therefore, in our opinion, declaration should be mandatory for all fragrance ingredients as well as straightforward so most consumers can understand it. Moreover, legislation should be improved to prevent inappropriately high exposures by forbidding stronger allergens, restricting maximum concentrations in the finished product or fields of application, delivering information regarding the risks to the general public, and controlling the compliance of manufacturers with the regulations. Besides, manufacturers should share information regarding the composition in the final products and provide physicians with samples of all fragrance chemicals whenever needed for patch test investigations.

Abstract
BACKGROUND Hand eczema (HE) in healthcare workers (HCWs) is common. Besides wet work, healthcare work also implies exposure to contact allergens. OBJECTIVES To assess HE and contact allergy related to occupational exposures in HCWs. METHODS In a cross-sectional study, 311 HCWs with HE within the preceding 12 months and a control group of 114 HCWs without HE were investigated with the baseline series and a special patch test series based on substances found in the gloves, soaps, alcoholic hand disinfectants and hand creams provided at the hospitals. RESULTS Contact allergy to rubber additives was significantly more common in HCWs with HE (6%) than in HCWs without HE (1%, P = .02). The corresponding percentages for fragrances were 11% and 3%, respectively (P = .004). Occupational HE was found in 193 of 311 (62%) HCWs. Of these, 22 of 193 (11%) had occupational allergic contact dermatitis, including 17 with glove-related rubber contact allergy. Contact allergy to diphenylguanidine was as common as contact allergy to thiurams. Occupational contact allergy to rubber additives was significantly associated with sick-leave related to HE. CONCLUSION Contact allergy to rubber additives in medical gloves is the most common cause of occupational allergic contact dermatitis in HCWs. Aimed patch testing with relevant rubber additives is mandatory when HE in HCWs is investigated.

Abstract
Skin decontamination is the primary intervention needed in chemical, biological and radiological exposures, involving immediate removal of the contaminant from the skin performed in the most efficient way. The most readily available decontamination system on a practical basis is washing with soap and water or water only. Timely use of flushing with copious amounts of water may physically remove the contaminant. However, this traditional method may not be completely effective, and contaminants left on the skin after traditional washing procedures can have toxic consequences. This article focuses on the principles and practices of skin decontamination.

Abstract
BACKGROUND Diagnostic classification of chronic hand eczema (CHE) represents a major clinical and taxonomic challenge because of its wide aetiological and clinical heterogeneity. AIM To develop an algorithm for the diagnosis and classification of CHE. METHODS Well-defined aetiological, clinical and morphological criteria of CHE were arranged graphically in a diagnostic hierarchy, and validated in 137 German patients with hand eczema. RESULTS The algorithm distinguished chronic hand eczema due to contact allergy, irritant damage or a combination of the two, each either with or without atopy, and also atopic hand eczema and idiopathic hand eczema lacking obvious causative factors. Foot involvement helped to distinguish idiopathic from irritant hand eczema. Each subtype could occur either with a hyperkeratotic-rhagadiform, dyshidrotic or mixed morphology, but certain hand eczema subtypes had clear morphological preferences. CONCLUSIONS By providing a more precise clinical definition this diagnostic algorithm could improve the classification and taxonomy of hand eczema subtypes, facilitating more rational treatment decisions and allowing better treatment outcome analysis.

Abstract
A cosmetic is classically defined as any preparation that is applied to the skin, eyes, mouth, hair or nails for the purpose of cleansing, enhancing appearance, giving a pleasant smell or giving protection. Unlike drugs, which are used to treat or prevent a disease in the body, cosmetics are not thought to change or affect the body's structure or functions. However, the distinction between drugs and cosmetics is sometimes not clear. Regulations for cosmetic products primarily address the safety of products that may be used by large populations of healthy consumers. However, the efficacy and safety of cosmetic products are not reviewed or approved by national authorities before they are sold to the public. The identification and analysis of adverse effects related to cosmetic products is a process that is currently still, to a large extent, industry driven. It is the responsibility of manufacturers to determine that products and ingredients are safe before they are marketed, and then to collect reports of adverse reactions. However, although the manufacturers do their best to monitor the safety profile of their products, we should consider that there is always a potential inherent conflict of interest.

Abstract
BACKGROUND The widespread use of fragrance-containing products is probably the most important reason for its high impact in allergic contact dermatitis. OBJECTIVES To describe the frequency of contact allergy to fragrance allergens as tested in the standard series, in relation to age, sex and lesion locations. To determine trends in frequency over the years and to study the association between positive tests observed with the different fragrance-allergy markers as well as between specific fragrance allergens and locations of the lesions. PATIENTS/METHODS 10 128 patients underwent patch testing between January 1990 and December 2005 at the Dermatology department in Leuven. RESULTS 1463 (14.5%), that is, 380 (26%) males and 1083 (74%) females, reacted positively to at least 1 fragrance-allergy marker in the standard series: 9% to fragrance mix I, 6% to Myroxylon pereirae, and 4.8% to colophonium (often in association), 2.1% to hydroxyisohexyl 3-cyclohexene carboxaldehyde and 2.1% to fragrance mix II, the latter 2 allergens having been introduced more recently. Over the years, fragrance contact allergy has shown a fluctuating trend. Hands and face were the most commonly affected body sites. Moreover, a significant association was found between specific fragrance allergens and certain locations. CONCLUSIONS This study illustrates that fragrance contact allergy is common in patients suffering from contact dermatitis.

Abstract
A 34-year-old woman referred episodes of gastrointestinal disorders and sometimes angioedema of the lips which appeared within 2 hours from the ingestion of packed food like biscuits, cereals or fruit juice. A patch test with the standard European series and with food preservatives was positive for fragrances mix. The avoidance of packed food labelled as containing flavours among the ingredients caused the disappearance of the above reported symptoms.

Abstract
Population-based studies on contact allergy with retesting of individuals are infrequently performed. Variable degrees of persistence are reported when individuals with contact allergy are retested with years in between. The patch test results of 270 individuals tested in 2005-2006 are presented and the pattern and frequency of sensitization discussed. Persistence when compared with patch test results from 1997-1998 is reported. 270 twin individuals with and without hand eczema underwent patch testing with the TRUE Test((R)) (Mekos Laboratories AS, Hilleroed, Denmark) in 1997-1998 and again in 2005-2006 as part of a larger study. In 2005-2006, a total of 74 (27.4%) of the 270 individuals had at least 1 positive patch test and 20 (7.4%) of the 270 had 2. The frequency in men and women was 9/90 (10%) and 65/180 (36.1%), respectively. The frequency of contact allergy in individuals with and without hand eczema was 59/185 (31.3%) and 15/85 (17.6%), respectively. The most prevalent contact allergies were to nickel, thiomersal, and fragrance mix I. All together, 74% of the positive reactions were reproduced. The frequency of contact allergy in this population-based cohort with hand eczema was comparable with previous reports. Persistence of contact allergy after many years was confirmed.

Abstract
To study the frequency of sensitization to 26 fragrances to be labelled according to current European regulation. During 4 periods of 6 months, from 1 January 2003 to 31 December 2004, 26 fragrances were patch tested additionally to the standard series in a total of 21 325 patients; the number of patients tested with each of the fragrances ranged from 1658 to 4238. Hydroxymethylpentylcyclohexene carboxaldehyde (HMPCC) was tested throughout all periods. The following frequencies of sensitization (rates in %, standardized for sex and age) were observed: tree moss (2.4%), HMPCC (2.3), oak moss (2.0), hydroxycitronellal (1.3), isoeugenol (1.1), cinnamic aldehyde (1.0), farnesol (0.9), cinnamic alcohol (0.6), citral (0.6), citronellol (0.5), geraniol (0.4), eugenol (0.4), coumarin (0.4), lilial (0.3), amyl-cinnamic alcohol (0.3), benzyl cinnamate (0.3), benzyl alcohol (0.3), linalool (0.2), methylheptin carbonate (0.2), amyl-cinnamic aldehyde (0.1), hexyl-cinnamic aldehyde (0.1), limonene (0.1), benzyl salicylate (0.1), gamma-methylionon (0.1), benzyl benzoate (0.0), anisyl alcohol (0.0). 1) Substances with higher sensitization frequencies were characterized by a considerable number of '++/+++' reactions. 2) Substances with low sensitization frequencies were characterized by a high number of doubtful/irritant and a low number of stronger (++/+++) reactions. 3) There are obviously fragrances among the 26 which are, with regard to contact allergy, of great, others of minor, and some of no importance at all.

Abstract
Allergic contact dermatitis is recognized as a public health problem and some major allergens have been subject to intervention aiming at lowering skin exposure. There is an obvious interest in evaluating the effect of such interventions. Population studies are difficult to perform and epidemiological studies based on clinical data from testing patients with contact dermatitis are common surrogates. Our objective was to gather Swedish clinical standard series test data on two occasions in order to monitor trends in sensitization rates. Consecutive patch test results from the Swedish standard series were collected from 9 centres from 1991 to 1993 and from 1999 to 2001. In total, 3680 and 3790 patients, respectively, were included. Crude, age-adjusted and age-stratified prevalence are given separately for women and men. Our top 10 allergens are much in line with newly published European test data. Significant changes among those allergens are increasing sensitization rates for Myroxylon pereirae and decreasing rates for colophony, 5-chloro-2-methyl-4-iso-thi-azo-lin-3-one, Amerchol L 101 and thiuram mix. Nickel allergy is decreasing among young women. Among less common allergens, a noteworthy increase of sensitization to 4-phenyl-en-diamine is found. In conclusion, significant trends in sensitization rates of important allergen, reflecting changes in exposure, have been found.

Abstract
The aim of this study is to find out the causes of skin diseases in one-third of the staff of a perfume factory, in which 10 different perfume sprays were being manufactured. Site inspection, dermatological examination and patch testing of all 26 persons at risk with 4 perfume oils and 30 ingredients of them. The results showed 6 bottlers were found suffering from allergic contact dermatitis, 2 from irritant contact dermatitis, 12 workers showed different strong reactions to various fragrances. The main causes of allergic contact dermatitis were 2 perfume oils (12 cases) and their ingredients geraniol (12 cases), benzaldehyde(9), cinnamic aldehyde (6), linalool, neroli oil, terpenes of lemon oil and orange oil (4 each). Nobody was tested positive to balsam of Peru. Job changes for office workers, packers or printers to other rooms, where they had no longer contact with fragrances, led to a settling. To conclude, automation and replacement of glass bottles by cartridges from non-fragile materials and using gloves may minimize the risk.

Abstract
Terpenes are widely used fragrance compounds in fine fragrances, but also in domestic and occupational products. Terpenes oxidize easily due to autoxidation on air exposure. Previous studies have shown that limonene, linalool and caryophyllene are not allergenic themselves but readily form allergenic products on air-exposure. This study aimed to determine the frequency and characteristics of allergic reactions to selected oxidized fragrance terpenes other than limonene. In total 1511 consecutive dermatitis patients in 6 European dermatology centres were patch tested with oxidized fragrance terpenes and some oxidation fractions and compounds. Oxidized linalool and its hydroperoxide fraction were found to be common contact allergens. Of the patients tested, 1.3% showed a positive reaction to oxidized linalool and 1.1% to the hydroperoxide fraction. About 0.5% of the patients reacted to oxidized caryophyllene whereas 1 patient reacted to oxidized myrcene. Of the patients reacting to the oxidized terpenes, 58% had fragrance-related contact allergy and/or a positive history for adverse reaction to fragrances. Autoxidation of fragrance terpenes contributes greatly to fragrance allergy, which emphasizes the need of testing with compounds that patients are actually exposed to and not only with the ingredients originally applied in commercial formulations.

Abstract
Clinical experimental studies on contact dermatitis (CD) often evaluate the effect of one allergen or one irritant at a time. In real life, the skin is often exposed to more allergens, more irritants or allergens and irritants in combination. This combined exposure may potentially influence irritant effects as well as allergenicity of the substances. Mechanisms for a changed response can be immunological effects or enhanced penetration. Knowledge about the influence on skin reaction of combined exposures may influence skin reactivity and is important for prevention of CD. For allergens, threshold values may be influenced by the presence of other allergens or irritants, and prevention of CD by regulation of threshold values may not be sufficient if this is not taken into account.

Abstract
Household and cleaning products often contain both allergens and irritants. The aim of this double-blinded, randomized, paired study was to determine whether patch testing with an allergen (hydroxycitronellal) combined with an irritant [sodium lauryl sulfate (SLS)] cause a stronger patch test elicitation reaction than patch testing with the allergen (hydroxycitronellal) alone, in patients previously patch tested positive to hydroxycitronellal. A stronger patch test elicitation reaction was defined as at least 1 day of patch test reading showing more positive patch tests (+, ++ or +++) on the forearm patch tested with 6 concentrations of SLS plus hydroxycitronellal than on the forearm tested with 6 concentrations of hydroxycitronellal alone and no day of patch test readings showing more positive tests on the hydroxycitronellal forearm. 15/20 (75%) had at least 1 day of patch test reading with more positive patch tests on the forearm patch tested with SLS plus hydroxycitronellal and no day of patch test readings with more positive patch tests on the forearm tested with hydroxycitronellal (P = 0.0253). Estimation of the blood flow with laser Doppler supported these findings.

Abstract
Fragrance allergy and hand eczema are both common among dermatological patients. Fragrance mix (FM) and its constituents have a recognized relevance to exposure to fine fragrances and cosmetic products. Based on extensive chemical analysis and database search, a new selection of fragrances was established, including 14 known fragrance allergens present in products to which hand exposure would occur. A non-irritating patch-test concentration for some fragrances was established in 212 consecutive patients. 658 consecutive patients presenting with hand eczema were patch tested with the European standard series and the developed selection of fragrances. 67 (10.2%) of the 658 patients had a positive reaction to 1 or more of our selection of fragrance chemicals present in the new selection. The most common reactions to fragrances not included in the FM were to citral, Lyral (hydroxyisohexyl-3-cyclohexene carboxaldehyde) and oxidized l-limonene. A concomitant reaction to the FM identified potential fragrance allergy in less than (1/2) of these patients. Exposure assessment and a statistically significant association between a positive patch test to our selected fragrances and patients' history support the relevance of this selection of fragrances. Those with a positive reaction to our selected fragrances were significantly more likely to have 1 or more positive patch tests in the standard series. This observation is the basis for the hypothesis concerning cross-reactivity and the effect of simultaneous exposure. The study found that fragrance allergy could be a common problem in patients with eczema on the hands.

Abstract
Recently, we showed that 10 x 2% of consecutively patch-tested hand eczema patients had a positive patch test to a selection of fragrances containing fragrances relevant to hand exposure. In this study, we used repeated skin exposure to a patch test-positive fragrance allergen in patients previously diagnosed with hand eczema to explore whether immersion of fingers in a solution with or without the patch-test-positive fragrance allergen would cause or exacerbate hand eczema on the exposed finger. The study was double blinded and randomized. All participants had a positive patch test to either hydroxycitronellal or Lyral (hydroxyisohexyl 3-cyclohexene carboxaldehyde). Each participant immersed a finger from each hand, once a day, in a solution containing the fragrance allergen or placebo. During the first 2 weeks, the concentration of fragrance allergen in the solution was low (approximately 10 p.p.m.), whilst during the following 2 weeks, the concentration was relatively high (approximately 250 p.p.m.), imitating real-life exposure to a household product like dishwashing liquid diluted in water and the undiluted product, respectively. Evaluation was made using a clinical scale and laser Doppler flow meter. 3 of 15 hand eczema patients developed eczema on the finger immersed in the fragrance-containing solution, 3 of 15 on the placebo finger and 3 of 15 on both fingers. Using this experimental exposure model simulating real-life exposure, we found no association between immersion of a finger in a solution containing fragrance and development of clinically visible eczema on the finger in 15 participants previously diagnosed with hand eczema and with a positive patch test to the fragrance in question.
