Contact dermatitides occur commonly among health care workers (HCWs). To contrast the atopic status and incidence, location, and final diagnosis of skin diseases afflicting HCWs versus non-HCWs (NHCWs) evaluated for suspicion of allergic contact dermatitis (ACD); and among the population diagnosed with ACD, to compare the incidence and occupational relatedness of allergens found in HCWs with the rates observed in NHCWs. Between July 1, 1994, and May 30, 2014, 2611 patients underwent patch testing by the senior author. Of these, 165 were classified as HCWs based on their primary occupation. Statistical analysis was done using a χ test. Health care workers were more likely than NHCWs to be women and to have hand dermatitis. Women, but not men, HCWs suffered more irritant contact dermatitis. Health care workers had significantly more work-related ACD, especially to formaldehyde, quaternium-15, 2-bromo-2-nitropropane-1,3-diol, cocamide diethanolamine (DEA), thiuram mix, carba mix, thimerosal, benzalkonium chloride, glutaraldehyde, and bacitracin. Only patients suspected of having ACD were tested. Our population was geographically limited to metropolitan Kansas City, MO and metropolitan New York, NY. Health care workers suffer more from occupational ACD, especially of the hands, than do NHCWs, including to allergens not present on available standard allergen series.

Since the working medical personnel including dentists and dental technicians mainly use their hands, it is understandable that the most common occupational disease amongst medical personnel is contact dermatitis (CD) (80%-90% of cases). Development of occupational CD is caused by contact of the skin with various substances in occupational environment. Occupational etiologic factors for dental personnel are foremost reactions to gloves containing latex, followed by various dental materials...

Since February 1993 the EPIDERM surveillance scheme has collected data on occupational skin disease from consultant dermatologists in the UK. Reporting by occupational physicians to the scheme began in May 1994 and was superseded in January 1996 by the Occupational Physicians Reporting Activity (OPRA). The schemes currently receive reports on incident cases from 244 dermatologists and 790 occupational physicians. An estimated total of 9937 cases of contact dermatitis reported by dermatologists was calculated from surveillance data; 8129 contact dermatitis cases were estimated from reports by occupational physicians. The annual incidence of occupational contact dermatitis from dermatologist reports was 6.4 cases per 100,000 workers and 6.5 per 100,000 from reports by occupational physicians, an overall rate of 12.9 cases per 100,000 workers. Manufacturing industries account for the greatest number of cases seen by both sets of reporting physicians, with health care employment second. Reports from dermatologists also indicate high rates of dermatitis in the personal service industries (mainly hairdressers and barbers) and in agriculture. With the exception of an increase in cases seen in nurses in both schemes, the numbers and proportions of cases of contact dermatitis within occupations have remained fairly constant over the 6-year reporting period. Agents accounting for the highest number of allergic contact dermatitis cases were rubber (23.4% of allergic cases reported by dermatologists), nickel (18.2), epoxies and other resins (15.6), aromatic amines (8.6), chromium and chromates (8.1), fragrances and cosmetics (8.0), and preservatives (7.3). Soaps (22.0% of cases), wet work (19.8), petroleum products (8.7), solvents (8.0), and cutting oils and coolants (7.8) were the most frequently cited agents in cases of irritant dermatitis. The national scope of the data, together with the parallel structure by which both dermatologists and occupational physicians report

The nonsteroidal anti-inflammatory drug carprofen was used in humans in the 1980s, before its withdrawal due to adverse effects. It re-emerged for veterinary uses, for which it is still widely prescribed, in the 1990s. There has been one previous report published of photoallergic contact dermatitis (PACD) in a pharmaceutical factory worker exposed to carprofen. Investigation of carprofen as a cause of PACD in pharmaceutical factory workers presenting with facial dermatitis. Photopatch testing to carprofen dilutions in two pharmaceutical factory workers and three healthy volunteer controls using the European consensus methodology. This was followed by testing of eight further employees, referred by occupational health services, in the same factory. The index patient suspected a problem with carprofen and was found to have PACD to carprofen. The second patient presented with a widespread, although especially photoexposed site, dermatitis and was initially labelled as having an 'unclassified dermatitis'. Only subsequently was her exposure (indirect; she did not work in the packaging section of the factory like the first patient) to carprofen recognized and testing confirmed both contact allergy and PACD to carprofen. One of three healthy volunteer controls had an active photoallergy sensitization event to carprofen starting 10 days after photopatch testing. Three of eight factory employees subsequently referred because of skin problems had carprofen PACD. Carprofen is a potent photoallergen. These cases emphasize the importance of photopatch testing, and considering agents not included in standard series, when investigating patients presenting with a photoexposed site dermatitis.

The diagnosis of combined allergic and irritant contact dermatitis is an accepted subdiagnosis for hand dermatitis, and it is often considered in a patient with contact dermatitis, a positive and relevant patch test result, and wet work exposure. We therefore hypothesize that it is arbitrary for wet work exposure to be taken into consideration in a patient with newly diagnosed relevant contact allergy. Furthermore, an overestimation of the diagnosis will probably occur if the criteria for wet work exposure are applied correctly, as many occupations have an element of wet work. To find the statistically expected number of combined allergic and irritant contact dermatitis cases in 1000 patients, and to evaluate the diagnostic criteria for the diagnosis. One thousand consecutive patients with occupational contact dermatitis from a hospital unit in Denmark were assessed. The expected number of cases with the diagnosis of combined allergic and irritant contact dermatitis was 0.33%, as compared with the observed number of 6.4%. Females occupied in wet occupations were often diagnosed with combined allergic and irritant contact dermatitis (p contact dermatitis should be used critically to avoid misclassification, and possible criteria for the diagnosis are proposed. © 2014 John Wiley & Sons A/S.

Lárraga-Piñones, G; Heras-Mendaza, F; Conde-Salazar, L

2012-12-01

In 2010, wind energy coverage in Spain increased by 16%, making the country the world's fourth largest producer in a fast-developing industry that is also a source of employment. Occupational skin diseases in this field have received little attention. The present study aims to describe the main characteristics of skin diseases affecting workers in the wind energy industry and the allergens involved. We performed a descriptive, observational study of workers from the wind energy industry with suspected contact dermatitis who were referred to the occupational dermatology clinic of the National School of Occupational Medicine (Escuela Nacional de Medicina del Trabajo) between 2009 and 2011. We took both a clinical history and an occupational history, and patients underwent a physical examination and patch testing with the materials used in their work. We studied 10 workers (8 men, 2 women), with a mean age of 33.7 years. The main finding was dermatitis, which affected the face, eyelids, forearms, and hands. Sensitization to epoxy resins was detected in 4 workers, 1 of whom was also sensitized to epoxy curing agents. One worker was sensitized to bisphenol F resin but had a negative result with epoxy resin from the standard series. In the 5 remaining cases, the final diagnosis was irritant contact dermatitis due to fiberglass. Occupational skin diseases are increasingly common in the wind energy industry. The main allergens are epoxy resins. Fiberglass tends to produce irritation. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

Allergic contact dermatitis, along with irritant contact dermatitis and immediate contact reactions, contact urticarial, are the most frequent dermatological occupational disease, but seldom reported to the National authorities. We performed a 3-year retrospective study at the allergology section in the Dermatology Clinic of the University Hospital of Coimbra to evaluate the main occupations diagnosed as occupational allergic contact dermatitis, most common allergens and the effect of the modification of the work station in the evolution of the disease. During 2012 - 2014 among the 941 patch tested patients, 77 (8.2%) were diagnosed with occupational allergic contact dermatitis, with 169 positive patch tests related to occupational exposure, 55 detected within the baseline and 114 in complementary test series. In most cases allergic contact dermatitis involved the hands (88.3%), main professional activities were nail estheticians and hairdressers due to the manipulation of (meth)acrylates, the most common allergen in the study. After the diagnosis, 27.3% abandoned the work, 23.4% changed the work station, 49% avoided exposure to the responsible allergen. Contact dermatitis resolved in 39% of the patients, improved in 39% but had no change in the remaining 22%. This study, although including only patients from the center of Portugal, evaluates a large sample of patients with different occupations studied with a larger variety of allergens. Apart from classical allergens and professions responsible for occupational allergic contact dermatitis that we found in lower numbers (thiuram mix, paraphenylenodiamine, chromium and cobalt in health care workers, hairdressers and in the building industry), (meth)acrylates tested outside the European and Portuguese Baseline Series were the main cause of occupational allergic contact dermatitis, namely in nail estheticians. Methylisothiazolinone, the second more frequent occupational contact allergen in the present study was

The aim of the study is to investigate risk factors for sensitization to preservatives and to examine to which extent different preservatives are registered in chemical products for occupational use in Denmark. A retrospective epidemiological observational analysis of data from a university hospital was conducted. All patients had occupational contact dermatitis and were consecutively patch tested with 11 preservatives from the European baseline series and extended patch test series during a 5-year period: 2009-2013. Information regarding the same preservatives in chemical products for occupational use ('substances and materials') registered in the Danish Product Register Database (PROBAS) was obtained. The frequency of preservative contact allergy was 14.2% (n = 141) in 995 patients with occupational contact dermatitis. Patients with preservative contact allergy had significantly more frequently facial dermatitis (19.9 versus 13.1%) and age > 40 years (71.6 versus 45.8%) than patients without preservative contact allergy, whereas atopic dermatitis was less frequently observed (12.1 versus 19.8%). Preservative contact allergy was more frequent in painters with occupational contact dermatitis as compared to non-painters with occupational contact dermatitis (p contact allergy to methylisothiazolinone and contact allergy to formaldehyde. Analysis of the registered substances and materials in PROBAS revealed that preservatives occurred in several product categories, e.g., 'paints and varnishes', 'cleaning agents', 'cooling agents', and 'polishing agents'. Formaldehyde and isothiazolinones were extensively registered in PROBAS. The extensive use of formaldehyde and isothiazolinones in chemical products for occupational use may be problematic for the worker. Appropriate legislation, substitution, and employee education should be prioritized.

Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Occupational skin diseases are a widespread problem. Despite numerous protective mechanisms, the skin remains vulnerable to new irritants found in the workplace. As a result, many workers in different occupations suffer from occupational skin diseases. From the data at Sanglah Hospital in Dermatology Department, it should be noted that there is increasing number of new cases of contact dermatitis in period of January 2000 until December 2005, from 10,16% until 13,36% in the next year and relatively stable in the next four years. Occupations commonly associated with contact dermatitis are agriculture workers, construction workers, dental workers, electronic workers, florists, food workers, hairdressers, haousekeeping personnel, machinist, mechanics, medical workers, office workers, photographers, printers, textile workers. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

Occupational Contact Dermatitis in the Canadian Aircraft Industry.

Science.gov (United States)

Loranger, Camille; Moreau, Linda; Sasseville, Denis

Aircraft building exposes workers to irritant and sensitizing products. The aim of this article was to study occupational dermatoses among aircraft workers over 25 years. The files of aerospace workers referred between 1990 and 2015 were extracted from the database of the McGill University Health Centre contact dermatitis clinic. These were subdivided according to demographics, type of work, patch testing results, and final diagnosis. Of 305 workers, 58% were 40 years or younger; one third were women. Onset of dermatitis varied from 2 months to 25 years, but 120 cases (39%) occurred during the first 3 years. Fifty-one percent of the cases involved assemblers, and 27% were composite material technicians, which were overrepresented as they constitute 10% of the workforce. Of the 305 workers, 152 suffered from allergic contact dermatitis, and 96 had irritant contact dermatitis. Of those with allergic contact dermatitis, 124 reacted to epoxy-based workplace products, but only 48 had positive patch tests to commercially available epoxy allergens. More than 60% of the cases of epoxy allergy would have been missed without testing with workplace products.

Contact dermatoses are common in mechanic and repair occupations. This study aimed to (1) estimate the prevalence of occupationally related contact dermatitis among mechanics/repairers patch tested from 1998 to 2014 by the North American Contact Dermatitis Group, (2) characterize responsible allergens and irritants, and their sources, and (3) compare results among 3 occupational subgroups (mechanics, electrical/electronic, and other). A cross-sectional analysis of patients patch tested by the North American Contact Dermatitis Group between 1998 and 2014. Of 38,784 patients patch tested, 691 (1.8%) were mechanics/repairers. Male sex (93.5%) and hand involvement (59.5%) were common overall. Occupationally related skin disease was more prevalent among vehicle and mobile equipment mechanics/repairers (52.7%) and other mechanics/repairers (41.4%) than electrical/electronic equipment mechanics/repairers (21.3%). Overall, carba mix, thiuram mix, and methylchloroisothiazolone/methylisothiazolone were the most common occupation-related clinically relevant allergens. Gloves, automotive vehicles, solvents, oils, lubricants, and fuels were the most common sources of responsible allergens. Common occupationally related allergens included rubber accelerators and the preservative methylchloroisothiazolone/methylisothiazolone.

Dermatitis, an approach from occupational medicine

Full Text Available Occupational dermatitis is one of the most common occupational diseases in clinical practice. Prevalence varies according to the job activities and types of exposure, with figures of up to 37% reported in the literature. Its origin may be irritant or allergic. Atopy and frequent hand washing or exposure to wetness or humidity is described has been described as risk factors, while evidence for gender and tobacco consumption, among others, is controversial. Diagnosis is based on physical examination, etiological patch testing and certification of occupational origin using standardized criteria. The condition has been associated with reduced productivity, absenteeism and occupational changes, as well as significant decreases in the quality of life of patients. Prevention is based primarily on education and restriction of exposure. These strategies are coupled with the treatment, which include the use of drugs such as topical steroids and calcineurin inhibitors.(X Close Abstract

Occupational skin disease is one of the most common occupational diseases. The hand is the most frequent site of involvement in occupational skin disease. We interviewed and examined patients seen in the Contact Dermatitis Clinic of the National Taiwan University Medical Center, a tertiary referral center in Taipei City. For patients suspected of having allergic skin diseases, patch testing was carried out using the European standard series and suspected allergens. Occupational hand dermatitis (OHD) was diagnosed according to medical history, work exposure, physical examination, and patch test findings. 36% of patients seen were diagnosed as having OHD. Electronics, hairdressing, medical, chemical, and construction were the most important industries causing OHD. In the 164 patients with OHD, 58.5% had irritant contact dermatitis (ICD) and 41.5% allergic contact dermatitis (ACD). Dorsal fingers, nail folds, and dorsal hands were most frequently involved in patients with ACD; dorsal fingers, volar fingers and fingertips were most frequently involved in those with ICD. Using logistic regression analysis, we were able to identify the most important clinical presentations that predicted the types of OHD, ACD versus ICD. Patients with atopic history and palm involvement were more likely to have ICD, and those with nail fold involvement more likely to have ACD. In patients with ACD, the most important allergens were dichromate, nickel, cobalt, fragrance mix, epoxy resin, thiuram mix, and p-phenylenediamine. In this study, we identified the important industries and causal agents for OHD. Future preventive measures focused on these industries and agents to reduce OHD will be warranted.

Workers are exposed to potential irritants and allergens with constant introduction of new industrial chemicals in the workplace. Characterize the final diagnoses, demographics, occupations, exposures, clinical presentations, patch test results, dermatologic histories, and risk factors of workers evaluated for suspected work-related allergic contact dermatitis (ACD). A retrospective chart review of 310 workers' compensation independent medical examinations evaluated for suspected work-related ACD was performed. Workers were seen in a community dermatology clinic in Portland, Oregon, from 2005 to 2014. Evaluation included history, physical examination, patch testing, and further diagnostic workup when indicated. Hand dermatitis was the most common presentation (n = 148, 47.7%). Prevalent occupations included health care workers (n = 51, 16.5%), custodial staff (n = 41, 13.2%), and machinists (n = 36, 11.6%). Allergic contact dermatitis (47.5%) was more common than irritant contact dermatitis (ICD) (38.9%) in those diagnosed as having occupational skin disease (n = 185). The highest-frequency work-related allergens were thiuram mix (21 of 88, 23.9%), carba mix (20 of 88, 22.7%), potassium dichromate (9 of 88, 10.2%), and epoxy resin (9 of 88, 10.2%). Allergic contact dermatitis and ICD are common occupational skin disorders. In this population of workers' compensation referrals, ACD was more common, with 73.3% of those cases work related, compared with 86.7% of ICD. Blue collar work and wet work were risk factors for the development of ACD and ICD.

Little is known about the epidemiology of contact dermatitis in production workers (PWs). The aims of this study were to estimate the prevalence of contact dermatitis and characterize clinically relevant and occupationally related allergens among North American PWs undergoing patch testing. This was a retrospective cross-sectional analysis of North American Contact Dermatitis Group data from 1998 to 2014. Of 39,332 patch-tested patients, 2732 (7.0%) were PWs. Among PWs, most were men (62.4%) and white (83.9%). A history of childhood eczema was uncommon (11.3%). Prevalent occupations included machine operators (27.3%); fabricators, assemblers, and hand-working occupations (16.8%); and precision metalworking occupations (16.1%). The most frequent sites of dermatitis were the hands (53.8%) and arms (29.4%), which were significantly more commonly affected compared with non-PWs (P contact dermatitis, and irritant contact dermatitis were also significantly more common in PWs (49.9% vs 10.6%, 58.9% vs 53.7%, and 32.7% vs 25.7%, respectively; all Ps contact dermatitis. Involvement of exposed body areas was common. Frequently identified allergens included adhesives/glues, rubber accelerators, metals, and preservatives.

The clinical part of the study aimed at describing epidemiological and diagnostic aspects of occupational Compositae dermatitis. Patch testing with the sesquiterpene lactone (SL) and Compositae mixes, feverfew extract and supplementary allergens in 250 selected gardeners showed Compositae allergy in 25, 17 females and 8 males. 24 were possibly occupationally sensitized. The mean age was lower and the preponderance of women higher compared to classical Compositae dermatitis, and the distribution and course of the dermatitis most often did not differ from other occupational plant dermatoses. The Compositae mix detected 2x as many as the SL mix, and the overall detection rate with both was 76%, making aimed patch testing necessary. Chrysanthemum (Dendranthema), marguerite daisy (Argyranthemum frutescens) and lettuce (Lactuca sativa) were frequent sensitizers. Occupational type I allergy to Compositae comprised sensitization to Gerbera, chrysanthemum, lettuce, Senecio cruentus and Aster. Among 1657 respondents in the questionnaire part of the study, 824 had worked with Compositae, and 160 (19%) reported occupational Compositae-related symptoms of skin and mucous membranes. Possible risk factors for the development of these were assessed in a stepwise logistic regression model and a history of childhood eczema, hay fever and duration of exposure were significantly associated with Compositae-related irritant and allergic symptoms in both sexes.

Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p -tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

An epidemiological study of occupational dermatitis in a tyre company and a cement company is reported. Ninety-seven percent of 999 tyre workers and 78% of 151 cement workers were screened by an occupational nurse and subsequently assessed by a specialist dermatologist. Prevalence rates of occupational contact dermatitis were 37 per 1000 and 68 per 1000 in the tyre and cement companies, respectively. Maintenance workers and tyre builders - particularly if they were Yugoslav and female - had high prevalence rates amongst tyre workers. Worker's compensation claim rates for the tyre company are similar to U.K. and U.S. rates for this industry. Prevalence rates of 37 per 1000 can be considered as a lower limit for this industry. The high prevalence rates in the cement company are noteworthy and require further study.

Limonene is widely used as a fragrance substance and solvent in cleansing products. Oxidized limonene is a frequent contact allergen among consumers of cosmetics, personal care products, and scented household cleaning products. Less is known about the sources of occupational exposure and occupational contact dermatitis caused by limonene. To report 14 patients with occupational contact allergy to limonene. The patients were examined in 2008-2013. An in-house preparation of oxidized limonene was patch tested as 3% and 5% in petrolatum from 2008 to August 2010, and after this as 3%, 1% and 0.3% pet. From 2012 onwards, a commercial test substance of limonene hydroperoxides was also used. We assessed the patients' occupational and domestic exposure to limonene. Occupational limonene allergy was observed in workers who used limonene-containing machine-cleaning detergents and hand cleansers, and in workers who used limonene-containing surface cleaners and dishwashing liquids similar to those used by consumers. In 3 cases, the occupational limonene allergy resulted from work-related use of limonene-containing, leave-on cosmetic products. Limonene is a frequent occupational sensitizer in hand cleansers and cleaning products. Occupational limonene contact allergy may also be caused by exposure to cosmetic products scented with limonene. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We report the patch test results of 449 construction workers who came as patients to the Occupational Dermatology Service of the Instituto Nacional de Medicina y Seguridad del Trabajo in Madrid between 1989 and 1993. 90.8% of them were patch tested, because they had cutaneous lesions or a clinical history suggestive of occupational dermatitis. 65.5% (268) of those patch tested showed one or more reactions connected with their work. Chromate at 42.1% was the main allergen, followed by cobalt, 20.5%, nickel, 10%, and epoxy resin, 7.5%. 25.9% (106) of patients showed sensitization to rubber components, the majority at 23.7% to thiuram mix, with TETD being the main allergen.

Since the working medical personnel including dentists and dental technicians mainly use their hands, it is understandable that the most common occupational disease amongst medical personnel is contact dermatitis (CD) (80%-90% of cases). Development of occupational CD is caused by contact of the skin with various substances in occupational environment. Occupational etiologic factors for dental personnel are foremost reactions to gloves containing latex, followed by various dental materials (e.g., metals, acrylates), detergents, lubricants, solvents, chemicals, etc. Since occupational CD is relatively common in dental personnel, its timely recognition, treatment and taking preventive measures is needed. Achieving skin protection at exposed workplaces is of special importance, as well as implementing necessary measures consequently and sufficiently, which is sometimes difficult to achieve. Various studies have shown the benefit of applying preventive measures, such as numerous protocols for reducing and managing latex sensitivity and other forms of CD in dentistry. Active involvement of physicians within the health care system, primarily dermatologists, occupational medicine specialists and general medicine doctors is needed for establishing an accurate medical diagnosis and confirmation of occupational skin disease.

Contact dermatoses are common in food service workers (FSWs). This study aims to (1) determine the prevalence of occupationally related contact dermatitis among FSWs patch tested by the North American Contact Dermatitis Group (NACDG) and (2) characterize responsible allergens and irritants as well as sources. Cross-sectional analysis of patients patch tested by the NACDG, 1994 to 2010, was conducted. Of 35,872 patients patch tested, 1237 (3.4%) were FSWs. Occupationally related skin disease was significantly more common in FSWs when compared with employed non-FSWs. Food service workers were significantly more likely to have hand (P contact dermatitis in FSWs were 30.6% and 54.7%, respectively. Although the final diagnosis of irritant contact dermatitis was statistically higher in FSWs as compared with non-FSWs, allergic contact dermatitis was lower in FSWs as compared with non-FSWs. The most frequent currently relevant and occupationally related allergens were thiuram mix (32.5%) and carba mix (28.9%). Gloves were the most common source of responsible allergens. The NACDG standard tray missed at least 1 occupationally related allergen in 38 patients (4.3%). Among FSWs patch tested by the NACDG between 1994 and 2010, the most common allergens were thiuram mix and carba mix. Gloves were the most common source of responsible allergens.

Hexavalent chromium in cement is a common cause of occupational allergic contact dermatitis (OACD). Analysis of patch test data during 1999 to 2013 was done. Patients with cement-induced chromate OACD filled the Dermatology Life Quality Index, graded 1 to 5. Of 4846 consecutive patients who were patch tested, 146 (3%) were chromate-sensitive. Of 46 (31.5%) who presented with chromate OACD, 27 (59%) had cement-induced chromate OACD. The proportion of chromate-sensitive patients with clinically relevant cement exposure increased from 7.7% in 2002 to 2004 to 28.7% in 2011 to 2013 (P = 0.04). The median age of presentation was younger than for other chromate-sensitive patients (32 vs 42 years). Hand eczema (88.9%) was the most frequent clinical presentation. Of the 27 with cement-induced chromate OACD, 21 (77.8%) had ongoing dermatitis at the time of the review. Although 14/27 (51.9%) changed their occupation to avoid exposure to cement, symptoms persisted in 9/14 (64.3%). Prolonged exposure to cement before development of symptoms was associated with chronicity. All the symptomatic patients experienced at least a moderate effect on their quality of life (grade 3 or higher on the Dermatology Life Quality Index). We recommend the adoption of the European legislation in Israel, to reduce the prevalence of chromate OACD from cement.

DeKoven, Samuel; DeKoven, Joel; Holness, D Linn

Recently, many cases of acrylate-associated allergic contact dermatitis have appeared among nail salon workers. Common acrylate-containing products in nail salons include traditional nail polish, ultraviolet-cured shellac nail polish, ultraviolet-cured gel nails, and press-on acrylic nails. Nail salon technicians seen in the occupational medicine clinic in 2015 and 2016 were identified, and their patch test results and clinical features were summarized. Patch testing was done with the Chemotechnique (Meth)Acrylate nail series, and either the North American Standard series or the North American Contact Dermatitis Group screening series. Six patients were identified, all women, ages 38 to 58. Common presentations included erythematous dermatitis of the dorsa of the hands, palms, and forearms and fissures on the fingertips. Less common sites of eruptions included the periorbital region, cheeks, posterior ears, neck, sacral area, lateral thighs, and dorsa of the feet. All patients reacted to hydroxyethyl methacrylate, and 5 patients reacted to ethyl acrylate. Each patient also reacted to (meth)acrylates that are not found on either standard series, including ethyleneglycol dimethacrylate, 2-hydroxypropyl methacrylate, and 2-hydroxyethyl acrylate. The authors report 6 cases of allergic contact dermatitis to acrylates in nail technicians seen over the past year, representing a new trend in their clinic. These cases are reflective of a growing trend of nail technicians with allergic contact dermatitis associated with occupational (meth)acrylate exposure. Efforts to improve prevention are needed.

An increased frequency of occupational contact hand dermatitis among surgical operating theatre personnel has been noticed. To evaluate patients with occupational contact dermatitis caused by their rubber gloves, and to describe a method for analysing the content of the allergens in the gloves. Patch tests were performed with the baseline series, a rubber chemical series, and the patients' own gloves. A method for analysing 1,3-diphenylguanidine (DPG) and cetylpyridinium chloride in the gloves was developed. Contact allergy to thiuram mix was found in 8 of 16 patients, whereas 12 of 16 patients reacted to DPG. In 7 of 8 patients, contact allergy to cetylpyridinium chloride was found. In the patients' gloves, cetylpyridinium chloride and DPG were detected at higher concentrations on the inside of the gloves than on the outside. Most patients had worked for decades in their present occupations, but their hand dermatitis had only been present for months. Contact allergy to DPG in gloves has been disputed, but, in this study, we were able to confirm the presence of DPG and cetylpyridinium chloride in the causative gloves by using a modified method for the analysis. The presence of these chemicals in gloves caused an increase in occupational contact dermatitis in surgical operating theatre personnel. © 2012 John Wiley & Sons A/S.

Tetraglycidyl-4,4'-methylenedianiline (TGMDA) is an aniline epoxy resin used in, for example, resin systems of pre-impregnated composite materials (prepregs) of the aircraft industry. Allergic contact dermatitis caused by TGMDA in prepregs has been described previously. To report on 9 patients with occupational allergic contact dermatitis caused by TGMDA in epoxy glues used in helicopter assembly. The patients were examined with patch testing at the Finnish Institute of Occupational Health in 2004-2009. The first patient was diagnosed by testing both components of two epoxy glues from the workplace, and was also tested with glue ingredients, including TGMDA. The following patients were tested with the glues and TGMDA. The resin parts of the glues were analysed for their epoxy compounds, including TGMDA. All of the patients had a patch test reaction to one or both of the resin parts of the TGMDA-containing glues. Eight of them had a strong allergic reaction to TGMDA, and one had a doubtful reaction to TGMDA. Two of the patients also had an allergic reaction to triglycidyl-p-aminophenol (TGPAP), another aniline epoxy resin, which was not present in the TGMDA-containing glues. In aircraft industry workers with suspected occupational dermatitis, aniline epoxy resins should be considered and patch tested as possible contact allergens. © 2015 John Wiley & Sons A/S.

Aircraft building exposes workers to irritant and sensitizing products. The aim of this article was to study occupational dermatoses among aircraft workers over 25 years. The files of aerospace workers referred between 1990 and 2015 were extracted from the database of the McGill University Health Centre contact dermatitis clinic. These were subdivided according to demographics, type of work, patch testing results, and final diagnosis. Of 305 workers, 58% were 40 years or younger; one third were women. Onset of dermatitis varied from 2 months to 25 years, but 120 cases (39%) occurred during the first 3 years. Fifty-one percent of the cases involved assemblers, and 27% were composite material technicians, which were overrepresented as they constitute 10% of the workforce. Of the 305 workers, 152 suffered from allergic contact dermatitis, and 96 had irritant contact dermatitis. Of those with allergic contact dermatitis, 124 reacted to epoxy-based workplace products, but only 48 had positive patch tests to commercially available epoxy allergens. More than 60% of the cases of epoxy allergy would have been missed without testing with workplace products.

Occupational dermatitis is a problem in the printing industry but can be avoided through adequate protective measures. Research into intervention implementation is fundamental to the success of a formal intervention effectiveness trial. The preliminary testing of four risk reduction strategies for occupationally caused dermatitis, which represent a range of approaches and cost implications. The strategies, the provision of (i) skin checks plus treatment advice; provision of (ii) gloves of the correct type/size plus use of an after-work cream; provision of (iii) information highlighting the problem of occupational dermatitis and (iv) development of a best practice skin care policy, were evaluated over 3 months in two non-randomly selected companies. A post-intervention evaluation into the effectiveness and efficacy of the intervention was also carried out. All interventions were found to be acceptable to some extent. No single intervention appeared to be completely effective. The most practical intervention appeared to be the regular use of gloves of the correct type and size. This preliminary intervention study has demonstrated an improvement in the skin condition of workers examined and points towards the need for further testing of risk reduction strategies for the prevention of dermatitis in the printing industry on a much larger scale.

Occupational contact dermatitis is one of the most common occupational diseases in Europe. In order to develop effective preventive measures, detailed and up-to-date data on the incidence, main causes and professions at risk of occupational contact dermatitis are needed. To describe the pattern of patch test reactivity to allergens in the European baseline series of patients with occupational contact dermatitis in different occupations. We analysed data collected by the European Surveillance System on Contact Allergy (ESSCA) network from 2002 to 2010, from 11 European countries. Allergens in the European baseline series associated with an at least doubled risk of occupational contact dermatitis include: thiuram rubber chemical accelerators, epoxy resin, and the antimicrobials methylchloroisothiazolinone/methylisothiazolinone, methyldibromo glutaronitrile, and formaldehyde. The highest risk of occupational contact dermatitis was found in occupations classified as 'other personal services workers', which includes hairdressers, nursing and other healthcare professionals, precision workers in metal and related materials, and blacksmiths, tool-makers and related trades workers. In the planning and implementation of measures aimed at preventing occupational contact dermatitis, the focus should be on the identified high-risk occupational groups and the most common occupational allergies. © 2015 John Wiley & Sons A/S.

Full Text Available Objectives: To evaluate sensitization to chemicals present in work environment after an outbreak of contact dermatitis in workers of vehicle equipment factory, exposed to polyurethane foam, based on 4,4'-diphenylmethane diisocyanate (MDI. Material and Methods: From among 300 employees, 21 individuals reporting work-related skin and/or respiratory tract symptoms underwent clinical examination, patch testing, skin prick tests, spirometry and MDI sIgE measurement in serum. Patch tests included isocyanates series, selected rubber additives, metals, fragrances, preservatives, and an antiadhesive agent. Results: Clinical examination revealed current eczema in the area of hands and/or forearms in 10 workers. Positive patch test reactions were found in 10 individuals, the most frequent to diaminodiphenylmethane and 4-phenylenediamine (7 persons. Reactions to an antiadhesive agent were assessed as irritant (5 workers. Except for sensitization to common aeroallergens, no significant abnormalities were found in the remaining tests. Occupational allergic contact dermatitis was diagnosed in 7 workers, irritant contact dermatitis in 10 and coexisiting allergic and irritant contact dermatitis in 3 workers. Conclusions: In workers manufacturing products from polyurethane foam, attention should be paid to the risk of developing contact dermatitis. Skin problems in our study group were attributable probably to insufficient protection of the skin.

Little is known about the epidemiology of contact dermatitis (CD) in print machine operators (PMOs). The aims of this study were to estimate the prevalence of CD and characterize clinically relevant and occupationally related allergens among PMOs undergoing patch testing. This was a retrospective cross-sectional analysis of the North American Contact Dermatitis Group data from 1998 to 2014. Of 39,332 patch-tested patients, 132 (0.3%) were PMOs. Among PMOs, most were male (75.0%) and white (92.4%). The majority were printing press operators (85.6%). The most frequent sites of dermatitis were hands (63.6%), arms (29.5%), and face/scalp (24.2%). More than half had an occupationally related skin condition (56.1%). Final diagnoses were most commonly allergic CD (58.3%) and irritant CD (33.3%). Cobalt (20.8%), carba mix (12.5%), thiuram mix (8.3%), and formaldehyde (8.3%) were the most frequent occupationally related allergens. The top allergen sources included inks (22.9%), gloves (20.8%), and coatings/dye/copy/photographic chemicals (14.6%). Allergic CD, irritant CD, and involvement of exposed body areas were common among PMOs. Common allergens included rubber accelerators, metals, and preservatives.

Irritant contact dermatitis (ICD) is a common diagnosis in patients with occupational contact dermatitis (OCD). Studies are lacking on the usefulness of material safety data sheets (MSDSs) in making the diagnosis of ICD. To characterize irritant exposures leading to the diagnosis of occupational ICD (OICD), and to evaluate the occurrence of concomitant exposures to contact allergens. We included 316 patients with suspected occupational hand dermatitis, referred to the Department of Dermato-Allergology, Copenhagen University Hospital Gentofte, Denmark during January 2010-August 2011, in a programme consisting of a clinical examination, exposure assessment, and extensive patch/prick testing. OCD was diagnosed in 228 patients. Of these patients, 118 were diagnosed with OICD. The main irritant exposures identified were wet work (n = 64), gloves (n = 45), mechanical traumas (n = 19), and oils (n = 15). Exposure to specific irritant chemicals was found in 9 patients, and was identified from MSDSs/ingredients labelling in 8 of these patients. Review of MSDSs and ingredients labelling showed that 41 patients were exposed to 41 moderate to potent contact allergens, and 18 patients were exposed to 25 weak workplace contact allergens. In the present study, the systematic exposure assessment did not reveal any new irritants. MSDSs have a limited role in the investigation of ICD. © 2014 John Wiley & Sons A/S.

Data regarding occupational contact dermatitis (OCD) and its effect on quality of life (QOL) in India are limited. To evaluate patients with OCD and record the outcome of treatment. All patients with OCD were evaluated for severity of disease (by the use of physician global assessment) and its effect on QOL (by use of the Dermatology Life Quality Index) questionnaire) at the first visit and after 3 months of treatment. Among 117 patients with OCD, hand eczema was present in 81.2%. Positive patch test reactions were found in 76%. The most common allergens were Parthenium hysterophorus and potassium dichromate. The most frequent diagnosis was occupational allergic contact dermatitis (OACD) (57%), caused by farming and construction work, followed by occupational irritant contact dermatitis (OICD) (24%), caused by wet work. Severe psychosocial distress was recorded in 62.5% of patients. After 3 months of treatment, 83% improved significantly, and 54% had improvement in QOL. Farmers were most frequently affected, followed by construction workers and housewives. OACD was found at a higher frequency than OICD. The most frequent allergens were Parthenium hysterophorus in farmers, potassium dichromate in construction workers, and vegetables in housewives. OCD has a significant impact on QOL. Patch testing, in addition to standard treatment, improves the outcome considerably. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Hand dermatitis in soldiers is a considerable problem. The purpose of the study was to evaluate appropriate screening tests to improve the diagnosis of hand dermatitis in soldiers. A group of 111 soldiers with occupational dermatitis from contact with fuels and oils underwent "tailored patch tests" with allergens relevant to their field of work and their environment. The control group consisted of 24 soldiers with various jobs similar to those of civilian life, who had not been exposed to oils and fuels. Seventy-three civilian patients, attending the clinic for patch testing, were also included. Twenty soldiers, who had a history of intensive contact with oil and fuels, but no contact dermatitis, and who were admitted because of various skin diseases (fungal infections, acne, etc.) also underwent the supplemental testing and served as an additional control group. Of the soldiers, 31 (29%) showed one or more positive skin tests of the oil series and 30 patients of this group one or more positive reactions to the standard patch tests trays. No patient of the control groups had a positive test to the oil series. Our results show the value of the supplementary tests as a first-step screening test for detection of oil allergy in soldiers and automobile-mechanics or in workers handling other gasoline- or diesel-powered engineering equipment. The test method appears to be practical, easy to perform, reliable and giving clear and accurate results, with a negligible rate of false positive reactions.

To quantify occupational ill health resulting from dermatitis in the UK printing industry and to explore links with particular processes and activities. Approximately 2600 members of the Graphical, Paper and Media Union living in Nottinghamshire were sent a self completion questionnaire. A sample of respondents, both those who reported current skin problems and those who did not, were invited for a short dermatological examination. The overall response rate was 62%. A total of 1189 respondents were directly involved in the printing industry and categorised according to work in pre-press (25%), printing (46%), or finishing (42%) processes. A total of 490 respondents (41%) self reported having a skin complaint at some time. Prevalence was highest in males (43%) and those working in printing (49%), in particular those who cleaned rollers and cylinders or who came into contact with substances containing isocyanates on a daily basis. The most commonly affected areas reported were the fingers and webs between the fingers. Twenty six per cent of the 490 reported a current problem on the hand. Reported symptoms included itching (61%), rash (58%), and dry skin (56%). Although certain printing industry substances were thought by respondents to aggravate their condition, constant washing and friction was most often cited. Reported use of protective equipment and cleansing products was generally high, particularly by printers. Clinical examination confirmed the high self reported prevalence and also identified a substantial proportion of mild cases which were not reported. The overall prevalence of occupationally related skin complaints is estimated to be 40%. A much higher prevalence of dermatitis has been identified than from routine surveillance schemes. The use of good quality records from unions with high membership facilitated access to workers across a range of company sites and printing processes. Validation of self reported symptoms through clinical examination was

Full Text Available Background: Allergic contact dermatitis is one of the important occupational hazards in construction workers and it often leads to poor quality of life of the workers with substantial financial loss. However, this is often a neglected entity. There are no past studies on the construction workers in Indian subcontinent. Objective: This pilot study has been done to assess the allergological profile among the workers engaged in construction of roads and bridges. Materials and Methods: The study was conducted among the workers working on construction of a bridge, flyover, and roads in West Bengal, India. Sixteen workers were selected on clinical suspicion. Ten were selected randomly and patch tested with Indian standard battery of patch test allergens. Analysis of reactions and relevance of positive test was assessed as per standard guidelines. Results: All the workers were men. Average age of workers was 24.8 years (range, 19-34 years. Dermatitis affected exposed parts in 93.75% and covered areas in 62.5%. Total positive test was 24 and relevant 11. Most common allergens were chromate (relevant allergy/RA: in 60% of patch tested workers, epoxy resin (RA: 30%, cobalt (RA: 20%, nickel (RA: 20%, thiuram mixture (RA: 10% and black rubber mix (RA: 10%. Two cases (20% had irritant contact dermatitis. Conclusion: The result indicated that chromate is the most frequent allergen among construction workers in this part of India. High frequency of involvement of the covered areas as well as the exposed areas highlighted the fact that the allergens had access to most body parts of the workers.

"Dermatitis" defined.

The term "dermatitis" can be defined narrowly or broadly, clinically or histologically. A common and costly condition, dermatitis is underresourced compared to other chronic skin conditions. The lack of a collectively understood definition of dermatitis and its subcategories could be the primary barrier. To investigate how dermatologists define the term "dermatitis" and determine if a consensus on the definition of this term and other related terms exists. A seven-question survey of dermatologists nationwide was conducted. Of respondents (n  =  122), half consider dermatitis to be any inflammation of the skin. Nearly half (47.5%) use the term interchangeably with "eczema." Virtually all (> 96%) endorse the subcategory "atopic" under the terms "dermatitis" and "eczema," but the subcategories "contact," "drug hypersensitivity," and "occupational" are more highly endorsed under the term "dermatitis" than under the term "eczema." Over half (55.7%) personally consider "dermatitis" to have a broad meaning, and even more (62.3%) believe that dermatologists as a whole define the term broadly. There is a lack of consensus among experts in defining dermatitis, eczema, and their related subcategories.

In recent years, the prevalence of contact allergy to isothiazolinones has reached epidemic levels. Few studies have presented data on occupations at risk of developing contact allergy to isothiazolinones. To present demographics and examine risk factors for sensitization to methylisothiazolinone (MI), methylchloroisothiazolinone (MCI) in combination with MI and benzisothiazolinone (BIT) in Danish dermatitis patients. A retrospective epidemiological analysis of data from three Danish hospitals departments was conducted. All patients consecutively patch tested with MI, MCI/MI and BIT between 2009 and 2013 were included. MI contact allergy showed a significantly increased trend in prevalence from 1.8% in 2009 to 4.2% in 2012 (p dermatitis mainly drove the increase in 2012. Adjusted logistic regression analysis showed that MI sensitization was significantly associated with occupational exposures, hand and facial dermatitis, age > 40 years, and the occupational groups of tile setters/terrazzo workers, machine operators, and painters. MCI/MI contact allergy was significantly associated with the following high-risk occupations: painting, welding (blacksmiths), machine operating, and cosmetology. The occupational group of painting was frequent in the group of patients with BIT contact allergy. Several high-risk occupations for sensitization to isothiazolinones exist. Regulation on the allowed concentration of isothiazolinones, and especially MI, in both consumer products and industrial products is needed. © 2014 John Wiley & Sons A/S.

Occupational irritant contact dermatitis (OICD) is a dif cult and hard to manage condition. It occurs more frequently in certain occupations where contact with harsh chemicals, use of alcohol-based disinfectants, and frequent hand washing heightens the risk. Treatment for OICD includes patient education in addition to physical, topical, and systemic therapies. To review the pathogenesis and treatment options for OICD and evaluate the ef cacy of a selective skin-care regimen involv- ing a hand protectant cream alone as well as combined with a repair cream and speci c cleanser. A single-center open study was performed comprising 42 healthy male and female adult volunteers prone to occupational irritant contact dermatitis due to frequent wet work or contact with detergents. Between day 0 and day 7, subjects applied a hand protectant cream as needed on both hands (at least twice daily). On days 7 to 14, subjects applied a hand protectant cream and cleanser as needed on both hands (at least twice daily) as well as a repair cream each evening. A diary log was given to each volunteer for application control and for a subjective evaluation of daily tolerability. In these subjects prone to occupational irritant contact dermatitis, the hand protectant cream applied during the initial 7-day period was effective in restoring the damaged skin barrier and improving the stratum corneum hydration. A regimen that combined the hand protectant and repair creams with a speci c cleanser during a further 7-day period allowed contin- ued improvement of skin hydration and additional clinical bene ts while respecting the skin barrier function. The results of this study support the use of a 3-step approach for patients who are at risk of repeated exposure to external irritants. J Drugs Dermatol. 2016;15(suppl 11):s81-85..

Background: The prevalence of atopic dermatitis (AD) has increased considerably in the last decades. The major predisposing factor for AD is an inherited epithelial barrier defect due to loss-of-function in the filaggrin gene. Environmental factors are also hypothesised to cause AD. The aim...... of the present study was to analyse whether maternal occupational exposure to allergens or irritants during pregnancy is associated with AD in the offspring. Methods: A total of 41,724 mother-child pairs from The Danish National Birth Cohort were categorized according to maternal occupational exposure assessed...... by combining occupation during pregnancy and a job exposure matrix. AD in the offspring was defined by a combination of parentally reported AD and eczema in locations typical for AD. Results: AD was identified in 14.9% and 11.7% of the children by age 18 months and 7 years, respectively. By age 18 months...

Full Text Available Allergic contact dermatitis is the delayed type hypersensitivity reaction to exogenous agents. Allergic contact dermatitis may clinically present acutely after allergen exposure and initial sensitization in a previously sensitized individual. Acute phase is characterized by erythematous, scaly plaques. In severe cases vesiculation and bullae in exposed areas are very characteristic. Repeated or continuous exposure of sensitized individual with allergen result in chronic dermatitis. Lichenification, erythematous plaques, hyperkeratosis and fissuring may develop in chronic patients. Allergic contact dermatitis is very common dermatologic problem in dermatology daily practice. A diagnosis of contact dermatitis requires the careful consideration of patient history, physical examination and patch testing. The knowledge of the clinical features of the skin reactions to various contactans is important to make a correct diagnosis of contact dermatitis. It can be seen in every age, in children textile product, accessories and touch products are common allergens, while in adults allergic contact dermatitis may be related with topical medicaments. The contact pattern of contact dermatitis depends on fashion and local traditions as well. The localization of allergic reaction should be evaluated and patients’ occupation and hobbies should be asked. The purpose of this review is to introduce to our collaques up dated allergic contact dermatitis literatures both in Turkey and in the World.

Recent advances in occupational dermatitis.

This review examined recent advances in occupational contact dermatitis (OCD). Both genetic and environmental factors contribute to OCD. There is continuing growth in our understanding of the genetic factors, particularly related to filaggrin mutations. In spite of increased understanding of irritant exposures, the prevalence of hand eczema in workers with wet work exposures remains high at approximately 20%. Patch test database surveillance systems have documented reductions in the occurrence of sensitivity to some allergens such as chromium wherein regulatory efforts have reduced workplace exposures. These surveillance data have also documented increases in sensitivity to several allergens in particular trades, serving as an effective system to identify new exposure situations or new allergens. The impact of OCD on quality of life and mental health conditions, employment and financial aspects is increasingly documented. Progress in understanding the underreporting of OCD and the underlying reasons continues. Several groups have developed robust multidisciplinary secondary and tertiary prevention programmes and the evaluations demonstrate promise. Although several recent systematic reviews have documented the evidence for various prevention strategies, there is increasing understanding of the gaps in prevention practices in actual workplaces. Understanding of the underlying genetic and environmental agents contributing to OCD is increasing. In spite of progress with reducing exposure to some allergens, the prevalence of OCD continues to be high, particularly related to wet work. New prevention programmes are being developed and evaluated and hold promise for improved outcomes.

Full Text Available Factors Related to Occupational Contact Dermatitis on Workers Exposed to Chemicals used at Industrial Automotive Company. Occupational contact dermatitis is one of skin disease in industrial settings which may reduce worker productivities. The occupational contact dermatitis occurs when workers are come into contact with chemicals at part of the worker’s body. This chemical contact could lead to an occupational contact dermatitis. The objective of this research is to investigate factors related to the occupational contact dermatitis at the worker who come into contact with chemicals used in industrial automotive company in Indonesia, Cibitung Jawa Barat. The study design is a descriptive research. The research subjects were selected using a stratified random sampling, and the total subjects were 54 person. The data were collected based on physical examination by a medical doctor, and the research questionnaire. Result from this study indicated that 74% (40 workers experience dermatitis contact: acute dermatitis contact 26% (14 workers, sub acute 39% (21 workers, and chronic 9% (5 workers. Furthermore, data analysis using a multivariate statistical analysis indicated that there are three major factors related to the occurence of contact dermatitis: duration of contact, frequency of contact and the use of personal protective equipment (PPE particularly gloves. In conclusion, incidence rate of occupational dermatitis contact at industrial setting is 65%/100 worker, and prevalence rate of occupational dermatitis contact at industrial setting is 74%/100 worker. In order to minimize the occupational contact dermatitis it is recommended to raise the workers awareness, the correct type of gloves used specifically to the type of chemicals, as well as improving the workers knowledge.

Return-to-work barriers for workers with contact dermatitis.

There is little information available regarding barriers to return-to-work (RTW) in workers with contact dermatitis. The purpose of this study was to survey occupational health and safety personnel to determine their perceptions regarding RTW barriers for workers with contact dermatitis. The study was conducted during an occupational health and safety research conference attended by stakeholders from labour, management, injured workers, government, safety associations, occupational health and safety practitioners and researchers. The attendees were presented with 3 pictures of varying degrees of work-related hand contact dermatitis and were asked to list the 3 key barriers or challenges in RTW for individuals with contact dermatitis. 21 individuals completed the survey. Issues identified in descending order of frequency were concern of ongoing dermatitis, ability to do the job safely, appearance, ability to accommodate, personal protective equipment, fear that the rash was contagious, workplace attitudes and pain. While some of these issues are potentially common to RTW situations in general, others are more specific to health problems which have a visible manifestation. Increased awareness of and attention to these possible barriers to RTW may lead to better RTW outcomes.

Airborne contact dermatitis (AirbCD) is not uncommon, according to a large number of published case reports and review articles. Epidemiological data on AirbCD based on larger clinical samples have not yet been published. To investigate demographic characteristics and patch test reactivity in patients diagnosed with both occupational and non-occupational AirbCD. A retrospective analysis of data from the Information Network of Departments of Dermatology (IVDK), 1994-2013, including 201 344 consecutively patch tested patients, was performed. One thousand two hundred and three patients (0.6%) were diagnosed with AirbCD, 421 (35.0%) of these with an occupational background. Occupational dermatitis and face involvement were more prevalent than in patients without AirbCD (n = 200 141). Sensitization to epoxy resin and sensitization to methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) were significantly associated with AirbCD, and there was a trend for sensitization to Compositae mix and/or sesquiterpene lactone mix to be associated with AirbCD. Adhesives, plastics, construction materials, paints and varnishes in occupational cases, and plants in non-occupational cases, were the most commonly documented culprit product categories. AirbCD is more common in patients with occupational dermatitis than in patients with non-occupational dermatitis. In our clinical sample, components of epoxy resin systems, MCI/MI and Compositae allergens were the most important contact allergens associated with AirbCD. Patch testing with additional allergens is important. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available The prevalence of contact dermatitis (CD in Europe varies between 6.7% and 10.6% depending on the sector of activity. Professional CD (PCD has an important economic impact − 30% of the budget compensation for occupational disease. In Romania, the prevalence of PCD is underestimated, with an even distribution of cases with respect to the allergic or irritative mechanism. A retrospective clinical study was conducted; target population being the patients admitted in Occupational Medicine Clinic Cluj-Napoca between 2003 and 2011. Objectives of study were: specifying the prevalence range of allergic CD (ACD / irritative CD (ICD among occupational/work-related diseases, the distribution of allergic/irritative CD (A/ICD for different sectors of activity and establishing the correlation between atopy and A/ICD. We have applied allergy skin tests - prick (environmental allergens and patch (occupational allergens. Inclusion criteria were: -documented occupational exposure at skin allergens/irritants; -the atopy state; -diagnostic established at discharge. Patients with recurrent chronic urticaria, angioedema, hypereosinophilic syndrome have been excluded. Statistical analysis was done using SPSS software. The study indicated a similar prevalence for A/ICD, with similar distribution. Prevalence above average has been recorded in the metallurgy sector (A/ICD, in health care sector (ACD, respectively, textile industry (ICD. The correlation atopy-ACD has proved to be lower compared to previous reports. Regarding ICD, the diagnostic was confirmed frequently to non-atopic persons. We strongly recommend the compliance with a multidisciplinary protocol for the management of A/ICD, individualized for specific activity sectors or even work stations.

A high contact dermatitis symptoms prevalence has been observed in Dutch construction workers. Contact dermatitis was diagnosed by an expert panel using questionnaire data and photographs of 751 subjects' hands. A subset was evaluated by two occupational physicians. Their diagnoses were compared to those of the expert panel. In addition, two self-reported questionnaire-based assessment methods were compared to the expert panel evaluation. Associations between contact dermatitis and determinants were assessed using log-binomial regression analysis. Contact dermatitis prevalence was high: 61.4% (expert panel's diagnosis) and 32.9% (self-reported). Agreement between occupational physicians and the expert panel was low but increased after training. Washing hands with solvents and performing job-related tasks at home were related to contact dermatitis. Contact dermatitis prevalence among construction workers is high. Recognition of contact dermatitis by occupational physicians is poor but can be improved by training. Awareness of skin disorders should be raised. © 2017 Wiley Periodicals, Inc.

Contact eczema to foods, spices, and food additives can occur in occupational and nonoccupational settings in those who grow, handle, prepare, or cook food. Pizza is one of the most eaten foods in every continent, and pizza making is a common work in many countries. We aimed to evaluate the occurrence and the causes of contact dermatitis in pizza makers in Naples. We performed an observational study in 45 pizza makers: all the enrolled subjects had to answer a questionnaire designed to detect personal history of respiratory or cutaneous allergy, atopy; work characteristics and timing were also investigated. Every subject attended the dermatology clinic for a complete skin examination, and when needed, patients were patch tested using the Italian baseline series of haptens integrated with an arbitrary pizza makers series. Our results reported that 13.3% of the enrolled pizza makers (6/45) presented hand eczema, and that 8.9% (4/45) were affected by occupational allergic contact dermatitis. Diallyl disulfide and ammonium persulfate were the responsible substances. Performing patch tests in pizza makers and food handlers affected by hand contact dermatitis is useful. We propose a specific series of haptens for this wide working category.

This metal is used in numerous industrial and consumer products, including stainless steel, magnets, metal plating, coinage, and special alloys, and is therefore almost impossible to completely avoid in daily life. Nickel contact dermatitis can represent an important morbidity, particularly in patients with chronic hand eczema, which can lead to inability to work, a decrease in quality of life and significant healthcare expenses. Therefore, its management is of great importance.

Compositae dermatitis is an allergic contact dermatitis caused by plant species of the Compositae family. The first report of a cutaneous reaction to the Chrysanthemum genus was made by Howe JS in 1887. In 1895 Maiden JH reported about skin lesions among men working with Tagetes minuta. Case reports of contact allergic-ragweed dermatitis appeared in the American literature as early as 1919. The North American feverfew--Parthenium Hysterophorus was brought to India from America in 1956 and it caused thousands of cases of so-called parthenium dermatitis. Ragweed and parthenium dermatitis became prototypes for the classic, so-called "airborne" Compositae dermatitis, that affects primarily exposed skin surfaces, and produces a universal erythroderma. The frequency of contact allergy to Compositae in Europe is higher than previously believed. It occurs most frequently in middle-aged and elderly persons, but also in all age groups. During the two past decades a more equal sex ratio has been established. The prevalence varies from 0.7-1.4% in the general population, up to 4.5% among occupationally exposed persons. Compositae allergy is among the top ten contact sensitivities in Europe. In North Europe plants were the cause of 4.4% cases of occupational allergic contact dermatitis. ETIOLOGY AND PATHOGENESIS: Among cultivated Compositae plants, Chrysanthemum is considered to be a major sensitizer in Europe (60%). Among the edible types, it is lettuce--Lactuca sativa and endive Cichorium endivia (20-30%), and wild-growing feverfew--Tanace--tum parthenium (70-90%), tansy--Tanacetum vulgare (54%), and dandelion--Taraxacum officinale (65%). Sesquiterpene lactones are the main sensitizers of the Compositae family. Other components, thiophenes and acetylenes are said to elicit only phytophotodermatitis, but recent studies have demonstrated that some thiophenes and benzofuran derivates possess not only phototoxic activity, but also sensitizing properties.

Allergic contact dermatitis is a common diagnosis resulting from exposure to a chemical or chemicals in a patient's personal care products, home, or work environment. Once patch testing has been performed, the education and management process begins. After the causative allergens have been identified, patient education is critical to the proper treatment and management of the patient. This must occur if the dermatitis is to resolve. Detailed education is imperative, and several resources are highlighted. Photoallergic contact dermatitis and occupational contact dermatitis are other considerations a clinician must keep in mind.

Raşcu, Agripina; Bucur, Letiţia; Naghi, Eugenia; Drăghici, B

2003-01-01

We present a derma-respiratory syndrome in a patient occupationally exposed to trichloroethylene (TCE). At the beginning of its industrial use trichloroethylene was considered harmless. But, in time it showed a high noxious capacity. It produces an important and various pathology, which evolves as acute or chronic disease. The case we present shows that trichloroethylene can induce cutaneous pathology that excels contact dermatitis. It also proves that trichloroethylene can produce systemic effects (obstructive respiratory syndrome). The particularity of the case is based on the succession of the events, first the cutaneous and then the respiratory effects. A long period of time was necessary for the installation of the symptoms (for cutaneous and bronchial sensitization to take place). The case presented is the proof that trichloroethylene's great toxicity cannot be doubted and that the clinical forms due to sensitization to trichloroethylene can be dramatic.

Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards and determined the prevalence of occupational skin diseases at a shoe manufacturing factory in Indonesia. A cross-sectional study on the observation of the working process and an inventory and risk assessment of exposure to the chemicals used. Classification of chemicals as potential sensitizers/irritants and qualitative assessments of these chemicals were done. Workers were examined and interviewed using the Nordic Occupational Skin Questionnaire-2002/LONG. The risk of Occupational skin diseases (OSD) at the shoe factory was mainly related to the exposure of the workers' skin to potential physical and chemical hazards in hot and humid environmental conditions. From a total of 514 workers, 8.5 % reported current OSD and 4.8 % reported a history of OSD. Occupational skin diseases were diagnosed in 29 % of the workers by dermatologists and 7.6 % had an occupational contact dermatitis (OCD). Of the 39 workers with contact dermatitis, 33 consented to being patch tested, 14 (3 %) workers showed a positive results and considered as having an occupational allergic contact dermatitis (OACD) and 25 (4.9 %) had an occupational irritant contact dermatitis (OICD). We observed a repeated and prolonged exposure of the workers to numerous physical and chemical skin hazards at this factory.

Trichloroethylene (TCE) has long been well known as a major pollutant that affects both occupational and general environments. Occupational medicamentosa-like dermatitis induced by TCE (OMLDT) is an autoimmune disease, which has become one of the critical occupational health issues in China. In this study, we analyzed 18 OMLDT patients and 29 professional TCE contact people on serum proteomic analysis by matrix-assisted laser desorption ionization time-of-flight mass spectrometry and ClinProTools bioinformatics software. The intensities of 35 protein/peptide peaks were significantly different between TCE contact controls and OMLDT patients. A pattern of six peaks (m/z 1,450.33, 1,866.16, 3,262.39, 4,109.55, 5,064.85 and 5,956.57) were selected to construct a diagnostic model to discriminate the OMLDT patients from controls with sensitivity and specificity of both 93.8 %. Our findings provide an alternative proteomic approach to differentiate the OMLDT patients from TCE contact workers with high sensitivity and high specificity, which will be of potential value in clinical diagnosis for occupational disease.

Full Text Available Contact dermatitis is a form of skin inflammation with spongiosis or intercellular edema of the epidermis due to the interaction of irritants and allergens. While occupational contact dermatitis is an inflammation of the skin due to exposure to irritants or allergens in the workplace. One of the jobs that have a high risk of the disease are construction workers. Although the disease is rarely-threatening but can cause high morbidity and suffering for workers, so it can affect the economy and quality of life of patients.

Occupational skin disease is common in healthcare workers. If the healthcare worker develops moderate to severe dermatitis, return to work (RTW) may be challenging. The study objectives were to review the impact of an RTW program on the work status of nurses with occupational hand dermatitis and to identify successful intervention methods and strategies. Nurses who received RTW services at a tertiary occupational medicine clinic were identified, and information related to their diagnosis and RTW was abstracted from their charts. Eighteen nurses with irritant hand dermatitis who received RTW services were identified. Twelve nurses (67%) were performing administrative duties because of their skin condition when admitted to the RTW program, and others were performing patient care with modifications. A graduated RTW trial was commonly implemented with optimized skin care management and monitoring by physicians and the RTW coordinator. Upon discharge, 14 nurses (78%) had returned to their nursing roles with direct patient care, 3 (17%) were working as nurses in non-patient care roles, and 1 (6%) was on permanent disability. A graduated RTW trial to reduce cumulative irritant exposure is a crucial strategy to facilitate nurses' transition back to work and to maintain direct patient care nursing roles.

The face is exposed to many foreign substances and may thus be a site of allergic contact dermatitis. Our aim is to elucidate the spectrum of factors associated with facial dermatitis by analyzing data of patients patch tested in the Information Network of Departments of Dermatology (IVDK) between 1995 and 2007. In 18,572 patients the main anatomical site of dermatitis was the face. Among these, the proportion of females and of patients with past or present atopic eczema was increased, while probable occupational causation was less common than in the overall group. Cosmetic allergens, as well as nickel, were significantly more common in women than men, including fragrance mix (10.8% vs. 8.3%), p-phenylenediamine (4.0% vs. 2.8%), lanolin alcohols (3.0% vs. 2.2%), Lyral(TM) (3.1% vs. 2.0%) and bufexamac (1.8% vs. 1.1%). In comparison, only epoxy resin contact allergy was diagnosed significantly more often in men than women: In patients with airborne contact dermatitis, over-represented allergens included sesquiterpene lactone mix, compositae mix, epoxy resin, (chloro-) methylisothiazolinone and oil of turpentine. In the clinical approach to patients with facial dermatitis, occupational airborne causation should be considered in addition to non-occupational (e.g., cosmetic) allergen exposure.

There is limited information regarding contact dermatitis (CD) associated with skin cleansers (SCs). The aim of the study was to evaluate the prevalence of allergic patch test (APT) reactions and irritant CD (ICD) associated with SCs. A retrospective cross-sectional analysis was performed using North American Contact Dermatitis Group data, 2000-2014. Of 32,945 tested patients, 1069 (3.24%) had either APT reaction or ICD associated with SCs. Of these, 692 (64.7%) had APT reaction only, 350 (32.7%) had ICD only, and 27 (2.5%) had both. Individuals with APT reaction and/or ICD were more likely to have occupationally related skin disease (relative risk [RR] = 3.8 [95% confidence interval {CI} = 3.3-4.5] for APT reaction and 10.0 [95% CI = 8.2-12.2] for ICD, respectively, P dermatitis (RR = 1.3 [95% CI = 1.1-1.6], P ≤ 0.001). Irritant CD was strongly associated with hand dermatitis (RR = 6.2 [95% CI = 5.2-7.3], P < 0.0001). More than 50 allergens were associated with SCs including quaternium-15 (11.2%), cocamidopropyl betaine (9.5%), methylchloroisothiazolinone/methylisothiazolinone (8.4%), coconut diethanolamide (7.9%), fragrance mix I (7.7%), Myroxylon pereirae (5.9%), 4-chloro-3,5-xylenol (5.8%), amidoamine (5.5%), and formaldehyde (4.4%). Many allergens, especially preservatives and surfactants, were associated with SCs. Most cases involved the hands and were occupationally related.

The increasing recognition of occupational origin of airborne contact dermatitis has brought the focus on the variety of irritants, which can present with this typical morphological picture. At the same time, airborne allergic contact dermatitis secondary to plant antigens, especially to Compositae family, continues to be rampant in many parts of the world, especially in the Indian subcontinent. The recognition of the contactant may be difficult to ascertain and the treatment may be even more difficult. The present review focuses on the epidemiological, clinical and therapeutic issues in airborne contact dermatitis. PMID:22345774

Health care workers are exposed to many agents that can cause irritant or allergic contact dermatitis. In nurses with eczema of the hands latex sensitivity can play an important role in the occurrence of urticaria, rhinitis and asthma. To determine the prevalence of irritant and allergic contact dermatitis and contact urticaria and the role of skin sensitization to common and occupational haptens and allergens in a group of health care workers with skin problems. Retrospective review of 204 health care workers assessed by prick and patch testing in an occupational health clinic. The diagnoses included 35.3% with irritant contact dermatitis, 64.7% with allergic contact dermatitis and 7.3% with contact urticaria to latex. Three workers complained of asthma and 5 complained of rhinitis related to latex sensitization. At present 12.9% of atopic subjects were sensitized to latex by skin prick against 21.9% in 1998, so sensitization showed a decline in the years considered. Contact dermatitis and sensitization to natural rubber latex is a significant problem and nurses should be tested for both types of hypersensitivity, as well as being patch tested to standard, rubber and disinfectants series. The need is stressed for preventive measures to prevent the onset of contact dermatitis and to avoid latex exposure.

Workers in the printing industry serve as an example of a working population that is at high risk of developing occupational skin disease. Daily exposures include both irritants and sensitizing agents. While many substances have been associated with occupational contact dermatitis in this population, no detailed cases of allergic contact dermatitis (ACD) from propylene glycol (PG) have been reported to date. We present a case of a printing tradesman who developed work-related ACD from PG and who was subsequently able to return to work after a multidisciplinary team assessment that included a comprehensive worksite visit by a clinical occupational hygienist.

Trichloroethylene (TCE) is an industrial solvent with widespread occupational exposure and also a major environmental contaminant. Occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) is an autoimmune disease and it has become one major hazard in China. In this study, sera from 3 healthy controls and 3 OMLDT patients at different disease stages were used for a screening study by 2D-DIGE and MALDI-TOF-MS/MS. Eight proteins including transthyretin (TTR), retinol binding protein 4 (RBP4), haptoglobin, clusterin, serum amyloid A protein (SAA), apolipoprotein A-I, apolipoprotein C-III and apolipoprotein C-II were found to be significantly altered among the healthy, acute-stage, healing-stage and healed-stage groups. Specifically, the altered expression of TTR, RBP4 and haptoglobin were further validated by Western blot analysis and ELISA. Our data not only suggested that TTR, RBP4 and haptoglobin could serve as potential serum biomarkers of OMLDT, but also indicated that measurement of TTR, RBP4 and haptoglobin or their combination could help aid in the diagnosis, monitoring the progression and therapy of the disease.

The widespread diffusion of low-quality products as well as the local cultural habits could be a relevant cause of allergic diseases in developing countries. In the present observational study, we explored the prevalence of allergic contact dermatitis in both rural and urban settings in northern Ethiopia, where skin diseases represent a frequent cause of morbidity. Clinical features and specific reactivities in association with environmental or occupational exposure were investigated. We patch tested 480 consecutive patients, visited at the Mekele IDC, exhibiting symptoms of contact dermatitis. A detailed medical history of each patient was collected. A positive patch-test response was observed in 50% of subjects; nickel was the most frequent sensitizer (26.2%), followed by p-tert-butylphenol formaldehyde resin (10%), fragrance mix (7.1%), potassium dichromate (5.4%), cobalt chloride (4.6%), disperse blue (2.3%), and p-phenylenediamine (1.7%). Gender-related differences were analyzed for single allergen. Eczema represented the most common manifestation, affecting the head and neck as primary skin areas. While reactivity to nickel interested almost all the occupational categories, sensitization to other allergens could be ascribed to working habits or environmental exposure. The results gathered from this study, the first one conducted within the Tigray region in Ethiopia, confirm the need to take appropriate measures to limit the nickel rate in metal objects and may be useful to design allergenic series suitable for patch testing in those geographical settings. © 2013 The International Society of Dermatology.

Fruit-derived organic compounds and detergents are relevant exposure factors for occupational contact dermatitis in the food industry. Although individuals with atopic dermatitis (AD) are at risk for development of occupational contact dermatitis, there have been no controlled studies on the effects of repeated exposure to multiple irritants, relevant for the food industry, in atopic skin. The aim of the study was to investigate the outcomes of repeated exposure to a fruit-derived organic acid and a detergent in AD compared to healthy volunteers. The volunteers were exposed to 2.0% acetic acid (AcA) and/or 0.5% sodium lauryl sulfate (SLS) in controlled tandem repeated irritation test. The outcomes were assessed by measurements of erythema, transepidermal water loss (TEWL) and natural moisturizing factor (NMF) levels. In the AD volunteers, repeated AcA exposure led to barrier disruption and significant TEWL increase; no significant differences after the same exposure in the healthy controls were found. Repeated exposure to SLS and the irritant tandems enhanced the reactions and resulted in a significantly higher increase in TEWL in the AD compared to the control group. Cumulative irritant exposure reduced the NMF levels in both groups. Differences in the severity of irritant-induced barrier impairment in atopic individuals contribute to the risk for occupational contact dermatitis in result of multiple exposures to food-derived irritants and detergents. © 2015 John Wiley & Sons A/S.

Allergic contact dermatitis caused by wood dust remains uncommon and most cases are occupational. Contact allergy to finished wooden products is even more rare and only few cases of contact dermatitis to wooden furnishings and furniture are described. During 2012-2014 surprisingly many patients with dermatitis associated to sauna baths were referred to our clinic. We report three novel cases with allergic contact dermatitis to western red cedar due to exposure during sauna baths. Three cases of non-occupational contact dermatitis to western red cedar were confirmed by patch testing. Allergic contact dermatitis to interior decoration or furniture is a rarity, but can be induced by novel exposures, like western red cedar in sauna interior decoration. © 2015 European Academy of Dermatology and Venereology.

Atopic dermatitis and hand eczema often impair the ability of people to work. Only a few studies have investigated whether individuals with loss-of-function filaggrin gene (FLG) mutations, who often have severe and early onset of dermatitis, experience occupational consequences. To investigate the personal consequences of having atopic dermatitis and/or hand eczema and FLG mutations. Adult Danes from the general population (n = 3247) and patients with atopic dermatitis and/or hand eczema (n = 496) were genotyped for common FLG mutations, and completed a questionnaire about skin symptoms and hand eczema. Socioeconomic variables, including disability pension, and information on work in risk occupations were retrieved from national registries. The reasons for granting disability pension were unknown. Disability pension was associated with hand eczema in the general population, especially among individuals with a history of atopic dermatitis. Moreover, self-reported hand eczema and atopic dermatitis were associated with particularly high risk of disability pension among FLG mutation carriers [odds ratio (OR) 4.02 and 95% confidence interval (CI): 1.15-14.11; and OR 6.01 and 95%CI: 2.37-15.34, respectively]. Furthermore, 60% of the FLG mutation carriers with atopic dermatitis who developed hand eczema had experienced symptoms before adulthood. In the general population, self-reported hand eczema and atopic dermatitis, particularly in individuals with a genetically impaired skin barrier, were associated with disability pension, suggesting that FLG mutations carriers with a history of atopic dermatitis and hand eczema could benefit from early attention with respect to choice of occupation. © 2017 John Wiley & Sons A/S.

To describe the characteristics of patients with occupational skin disease (OSD) in a tertiary referral clinic in Victoria, Australia. A retrospective review was conducted of records from patients seen at the Occupational Dermatology Clinic in Melbourne, Australia between 1 January 1993 and 31 December 2010. Of the 2894 people assessed in the clinic during the 18-year period, 44% were women and 56% were men. In all, 2177 (75%) were diagnosed with occupational skin disease (OSD). Of the patients with a work-related skin condition, 45% (n = 979) were considered to be atopic. The most common diagnosis in those with OSD was irritant contact dermatitis (ICD) (44%), followed by allergic contact dermatitis (33%) and endogenous eczema (11%). Women were significantly more likely to have soaps and detergents (P Occupational groups with the highest incidence of OSD were the hair and beauty professions (70 per 100 000), followed by machine and plant operators (38 per 100 000) and health-care workers (21 per 100 000). We confirm the importance of occupational contact dermatitis as the most common cause of OSD, with ICD being the most common diagnosis. There are differences in the causes of ICD between our group of male and female workers. For the first time in Australia, rates of OSD in certain industries have been calculated. © 2015 The Australasian College of Dermatologists.

In clinical practice, contact dermatitis is a relatively common skin complaint, whose prevalence has increased in recent years. Study by patch testing is essential for diagnosis of contact sensitization. To study the prevalence of sensitization to different allergens in a standard battery and observe the influence of different epidemiological and clinical variables on contact sensitization. A large number of allergens were included in our battery in order to detect new sensitizations whose prevalence might justify further study. This was a retrospective, observational, epidemiological study of 1092 patients, conducted in our skin allergy unit between January 1, 2000, and December 31, 2005. All patients were studied with a battery of 51 allergens. We assessed the following variables: sex, age, type of referral, occupation, site and course of skin lesions, personal and family history of atopy, positive patch tests, clinical significance, diagnosis, source of sensitization, and occupational relationship. At least 1 positive result was found in 55% of the patients, and 55.7% presented atopic dermatitis in one of its clinical variants: allergic contact dermatitis (28.2%), irritant contact dermatitis (20.1%), photoallergic contact dermatitis (2.2%), and phototoxic contact dermatitis (1.2%). The most prevalent allergens were nickel sulfate (29.3%), palladium chloride (11.7%), cobalt chloride (10.8%), potassium dichromate (7.5%), fragrance blends (6.3%), and p-phenylenediamine (6.1%). A positive occupational relationship was found in 41.1%, and 21.3% of the patients studied were diagnosed with occupational contact dermatitis. Metal workers, construction workers, and professional hairdressers were the most strongly represented groups. The most common source of sensitization was contact with metallic objects, followed by drugs, cosmetics, and rubber items. Female sex was the only independent variable that had a significant influence on the risk of contact sensitization in

Methotrexate, a folate antimetabolite, is used to treat atopic dermatitis and psoriasis. Although methotrexate's therapeutic efficacy has been noted in the literature, there are few data on the efficacy of methotrexate treatment for allergic contact dermatitis. To evaluate the efficacy and tolerability of methotrexate in treating allergic contact dermatitis at a single institution, and also to assess methotrexate efficacy in patients with chronic, unavoidable allergen exposure. We performed a retrospective chart review of 32 patients diagnosed with allergic contact dermatitis by positive patch test reactions, and who received treatment with methotrexate from November 2010 to November 2014. Demographic and treatment-associated data were collected from electronic medical records. Ten patients were identified as allergen non-avoiders secondary to their occupation, and were subgrouped as such. Seventy-eight per cent (25/32) of patients showed either a partial or a complete response. Methotrexate had a comparable efficacy rate in the allergen non-avoiders subset, at 10 of 10. Of the 32 patients, 23% (5/22) had complete clearance of their dermatitis, and 1/10 of allergen non-avoiders had complete clearance of their dermatitis. Methotrexate is a well-tolerated and effective treatment for allergic contact dermatitis, and shows comparable efficacy to immunomodulatory agents such as cyclosporine and azathioprine, with robust efficacy despite persistent allergen exposure in patients with allergic contact dermatitis. © 2017 John Wiley & Sons A/S.

Goodier, Molly C; Ljungberg, Linda; Persson, Christina; Engfeldt, Malin; Bruze, Magnus; Warshaw, Erin M

A 33-year-old woman presented to our clinic for suspected photoallergic contact dermatitis with a recent episode of severe, vesicular dermatitis involving exposed skin and correlating with relocation to a new home. Biopsy results showed spongiotic and lichenoid dermatitis with eosinophils. Patch test results showed a very strong (+++) reaction to methylisothiazolinone (MI), mild (+) reaction to MI/methylchloroisothiazolinone, and no reaction to benzisothiazolinone. These allergens were found in several personal products. However, the patient was suspicious of 4 wall paints recently used in her home. Semiopen patch tests to 3 Behr interior paints showed positive results. Nine controls showed negative results. High-performance liquid chromatography demonstrated MI and benzisothiazolinone in all 4 paints at concentrations ranging from 50 to 100 ppm and 290 to 340 ppm, respectively. Although MI has been reported to cause occupational airborne contact dermatitis in European household painters, to our knowledge, this is the first documented case of paint-related MI allergy in the United States.

Nickel allergy is prevalent as assessed by epidemiological studies. In an attempt to further identify and characterize sources that may result in nickel allergy and dermatitis, we analysed items identified by nickel-allergic dermatitis patients as causative of nickel dermatitis by using the dimethylglyoxime (DMG) test. Dermatitis patients with nickel allergy of current relevance were identified over a 2-year period in a tertiary referral patch test centre. When possible, their work tools and personal items were examined with the DMG test. Among 95 nickel-allergic dermatitis patients, 70 (73.7%) had metallic items investigated for nickel release. A total of 151 items were investigated, and 66 (43.7%) gave positive DMG test reactions. Objects were nearly all purchased or acquired after the introduction of the EU Nickel Directive. Only one object had been inherited, and only two objects had been purchased outside of Denmark. DMG testing is valuable as a screening test for nickel release and should be used to identify relevant exposures in nickel-allergic patients. Mainly consumer items, but also work tools used in an occupational setting, released nickel in dermatitis patients. This study confirmed 'risk items' from previous studies, including mobile phones.

The restaurant industry is a rapidly growing sector in Singapore and workers in this industry are trained in culinary skills but not on recognition of safety and health hazards and their control measures. Anecdotal clinical evidence has suggested an increased prevalence of occupational dermatoses among restaurant workers. To determine the prevalence and risk factors for contact dermatitis and burns among restaurant, catering and fast-food outlet (FFO) staff. Workers were interviewed and then clinical examination and patch and/or prick tests were conducted in selected individuals. In total, 335 of 457 workers (73% response) were interviewed and 65 (19%) had occupational dermatitis or burns and were examined. Of these, contact dermatitis was the commonest diagnosis, with a 12-month period prevalence of 10% (35 workers) and 3-month period prevalence of 8% (26 workers). All 35 workers had irritant contact dermatitis (ICD) and there were no cases of allergic contact dermatitis. The adjusted prevalence rate ratios of risk factors for ICD were 2.78 (95% CI 1.36-5.72) for frequent hand washing >20 times per day, 3.87 (95% CI 1.89-7.93) for atopy and 2.57 (95% CI 1.21-5.47) for contact with squid. The 3-month period prevalence for burns was 6% (20 workers). Ten workers had other occupational dermatoses such as work-related calluses, paronychia, heat rash and allergic contact urticaria to prawn and lobster. ICD and burns are common occupational skin disorders among restaurant, catering and FFO workers.

Occupational contact dermatitis (OCD) is a common occupational disease. Evidence suggests that education and training are effective prevention strategies. In spite of these known prevention strategies, workers continue to develop OCD. Little is reported regarding the actual training experience of workers. To examine the training experience of workers with contact dermatitis to identify areas for improvement. Participants were workers being assessed for contact dermatitis in an occupational health clinic. The anonymous survey collected demographics, workplace characteristics, and education and prevention practices. Approximately 80% reported general occupational health and safety training; however, only 49% reported skin-specific training (SST). For workers reporting SST, most received information regarding exposure avoidance, hand washing, and glove use. This content was reported as helpful by at least 50%. Workers who did not receive SST indicated the most important content would be warning signs of skin problems, how to avoid exposure and skin care while using gloves. While the study was anonymous and used self-reported of training experience, the study suggests there are gaps in skin protection training. Addressing these gaps may lead to improved prevention and reduction in OCD. © The Author(s) 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

A self-completion questionnaire sent to 2600 Nottinghamshire members of the Graphical Paper and Media Union elicited a 62% response. Forty one per cent of respondents reported suffering a skin complaint at some time and 11% had a current skin problem on the hand. This paper reports the validation stage of the study. Samples of 45 'cases' of self-reported dermatitis and 60 'controls', who reported they had never suffered a skin complaint, were clinically examined. All 45 self-reported cases were clinically confirmed as dermatitis. Occupationally related irritant contact dermatitis (ICD) was diagnosed in 20 (44%); 26 (58%) complaints were thought to be induced or exacerbated by occupation. Of the controls, 21 (35%) were also diagnosed with a skin complaint, the majority being mild, with an occupational association in 17, the majority (15) being ICD. Sixteen ICD cases were patch tested resulting in positive reactions to colophony, neomycin, nickel and potassium dichromate (2 of each). Two cases of basal cell carcinoma on the face were also identified, of which the participants were unaware. Although there was no false positive self-reporting there was a considerable number of false negatives, demonstrating the importance of clinical validation of questionnaires relating to industrial skin disease. This study has highlighted the need for improvement in skin care provision in the printing industry.

Cocamide DEA (CAS no. 68603-42-9) is a non-ionic surfactant frequently used in industrial, household and cosmetic products for its foam-producing and stabilizing properties. Contact allergy has been reported quite rarely in the past, but recently several cases were published, raising the question of an increase in the frequency of allergic dermatitis caused by this substance. To describe cocamide DEA-allergic patients and their characteristics observed in our department. Medical charts of patients, investigated between 1990 and December 2015, were retrospectively reviewed for cocamide DEA-allergy. Demographic characteristics and patch test results were analyzed. Out of 1767 patients tested, 18 (1%) presented with an allergic reaction to cocamide DEA, all of them at least with hand dermatitis. Twelve patients had (past) occupational exposure to cocamide DEA. Out of the 18 patients, 15 showed (most often) multiple positive reactions and 7 also suffered from atopic dermatitis. Cocamide DEA allergy is relatively rare, despite frequent use, and an increasing trend was not observed. Reactions to cocamidopropyl betaine and cocamide MEA only occurred in some of the subjects tested. Shampoos and liquid hand soaps/cleansers dominated as sources of exposure. All patients presented with an impaired skin barrier due to atopic and/or previous contact dermatitis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Atopic dermatitis is an inflammatory skin disease with early onset and with a lifetime prevalence of approximately 20%. The aetiology of atopic dermatitis is unknown, but the recent discovery of filaggrin mutations holds promise that the progression of atopic dermatitis to asthma in later childhood...... may be halted. Atopic dermatitis is not always easily manageable and every physician should be familiar with the fundamental aspects of treatment. This paper gives an overview of the natural history, clinical features, and treatment of atopic dermatitis....

Full Text Available Background: Preservatives present in cosmetics and other industrial products can cause allergic contact dermatitis. The aim of the study was to assess the frequency of allergy to selected preservatives in consecutive patients examined due to contact dermatitis in the Nofer Institute of Occupational Medicine, Łódź, and to establish whether individuals sensitized to formaldehyde react simultaneously to formaldehyde releasers. Material and Methods: A group of 405 patients (308 females and 97 males was examined in 2011–2013. In all participants patch tests with a series of 13 preservatives (paraben mix, formaldehyde, Quaternium 15, chloromethylisothiazolinone/methylisothiazolinone mix, methyldibromoglutaronitrile, diazolidinyl urea, imidazolidinyl urea, DMDM hydantoin, 2-bromo-2-nitropropane-1,3-diol, iodopropynyl butylcarbamate, benzalkonium chloride, sodium metabisulfite, produced by Chemotechnique Diagnostics, Sweden were performed. Results: Of the 405 patients 74 (including 52 females showed positive results of patch tests. Contact allergy to at least 1 preservative was noted in 47 (11.6% patients, including 34 (11% females and 13 (13.4% males. Methylisothiazolinone proved to be the most frequent sensitizer – 4.7% (5.2% females, 3.1% males while parabens, 2-bromo-2-nitropropane-1,3-diol and imidazolidinyl urea (0.2% were found to be the least frequent. Fourteen (3.4% participants, 10 women and 4 men, were allergic to formaldehyde and/or formaldehyde releasers. In 11 (78.6% of them monovalent hypersensitivity was observed. In 13 (3.2% of the examined group patients allergy to preservatives might have been of occupational origin. Conclusions: Preservatives, particularly isothiazolinones, are significant causal factors of allergic contact dermatitis, including occupational cases. Individuals sensitized to formaldehyde may react simultaneously to formaldehyde releasers, however, such reactions are relatively rare. Med Pr 2015;66(3:327–332

The European Union (EU) strategy for health and safety at work underlines the need to reduce the incidence of occupational diseases (OD), but European statistics to evaluate this common goal are scarce. We aim to estimate and compare changes in incidence over time for occupational asthma, contact dermatitis, noise-induced hearing loss (NIHL), carpal tunnel syndrome (CTS) and upper limb musculoskeletal disorders across 10 European countries. OD surveillance systems that potentially reflected nationally representative trends in incidence within Belgium, the Czech Republic, Finland, France, Italy, the Netherlands, Norway, Spain, Switzerland and the UK provided data. Case counts were analysed using a negative binomial regression model with year as the main covariate. Many systems collected data from networks of 'centres', requiring the use of a multilevel negative binomial model. Some models made allowance for changes in compensation or reporting rules. Reports of contact dermatitis and asthma, conditions with shorter time between exposure to causal substances and OD, were consistently declining with only a few exceptions. For OD with physical causal exposures there was more variation between countries. Reported NIHL was increasing in Belgium, Spain, Switzerland and the Netherlands and decreasing elsewhere. Trends in CTS and upper limb musculoskeletal disorders varied widely within and between countries. This is the first direct comparison of trends in OD within Europe and is consistent with a positive impact of European initiatives addressing exposures relevant to asthma and contact dermatitis. Taking a more flexible approach allowed comparisons of surveillance data between and within countries without harmonisation of data collection methods. Published by the BMJ Publishing Group Limited.

Full Text Available Methyldibromoglutaronitrile (MDBGN is a preservative found in cosmetics as well as in products for industrial use. It caused an outbreak of allergic contact dermatitis in Europe in the 1990s and early 2000s. To assess the prevalence of MDBGN sensitization among consultants in the occupational dermato-allergology unit of Farhat Hached University Hospital in Sousse-Tunisia, we carried out a study of all cases of contact dermatitis to MDBGN confirmed by patch-tests from 1 January 2011 to 31 December 2015. The prevalence of allergic contact dermatitis to MDBGN was 4.5% of all cases of contact dermatitis recorded during the same period with an increase from 1.7% in 2011 to 5.4% in 2015. Associated allergens with contact dermatitis to MDBGN were the Peru balsam in 4 cases, nickel sulfate and kathon CG in 3 cases each. Contact dermatitis to Dibromodicyanobutane was associated with sensitization to other preservatives in 4 cases and cosmetic allergens in 6 cases. An increasing rates of sensitization are noticed in our region. The absence of legal restrictions regarding this preservative agent may explain an increase of its use in non-European countries.

Full Text Available Background and Design: Occupational contact dermatitis (OCD is responsible for 80-90% of the occupational dermatoses. The aim of this work was to evaluate the clinical features of patients with OCD admitted to our hospital. Materials and Methods: The records of patients, who were admitted to our hospital with OCD between December 2009 and January 2013, were evaluated retrospectively. One hundred fifty-nine patients, who were diagnosed with OCD according to the Mathias criteria, were included in the study. Age, sex, location of the lesions, atopic status, glove use, occupational exposure time and total IgE levels of the patients were assessed. Patients with positive allergic reaction with "European Standard Series Skin Patch Test" were identified as allergic OCD and patients with negative test results as "irritant OCD". The clinical features and patch results of patients are evaluated. Results: One hundred fifty-nine patients with a mean age of 39±7.9 years consisted of 151 men and 8 women. The hands were the most common site of OCD; the palms were the most common affected areas of hand eczema. Eighty-one patients (50.1% were identified to have allergic OCD and 78 (49.9% as irritant OCD. Irritant OCD was most commonly seen in dental technicians, whereas allergic OCD was most commonly seen in tailors. The top 3 most frequent allergens were potassium dichromate (15.1%, nickel sulfate (9.11% and cobalt chloride (10.7%. Conclusion: In our country, there has been no comprehensive study presenting the clinical and descriptive characteristics of OCD. For preventing OCD and reducing sick leave we need to have data that belong to our country. Consequently, multicenter studies should be performed for establishing our own database on OCD.

Occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) is an autoimmune disease and it has become a serious occupational health hazard. In the present study, we collected fasting blood samples from patients with OMLDT (n = 18) and healthy volunteers (n = 33) to explore serum peptidome patterns. Peptides in sera were purified using weak cation exchange magnetic beads (MB-WCX), and analyzed by matrix-assisted laser desorption ionization time-of-flight-mass spectrometry (MALDI-TOF-MS) and ClinProTools bioinformatics software. The intensities of thirty protein/peptide peaks were significantly different between the healthy control and OMLDT patients. A pattern of three peaks (m/z 2106.3, 2134.5, and 3263.67) was selected for supervised neural network (SNN) model building to separate the OMLDT patients from the healthy controls with a sensitivity of 95.5% and a specificity of 73.8%. Furthermore, two peptide peaks of m/z 4091.61 and 4281.69 were identified as fragments of ATP-binding cassette transporter family A member 12 (ABCA12), and cationic trypsinogen (PRRS1), respectively. Our findings not only show that specific proteomic fingerprints in the sera of OMLDT patients can be served as a differentiated tool of OMLDT patients with high sensitivity and high specificity, but also reveal the novel correlation between OMLDT with ABC transports and PRRS1, which will be of potential value for clinical and mechanistic studies of OMLDT. - Highlights: • Identify 30 differential protein/peptide peaks between OMLDT and healthy control • The test sensitivity and test specificity were 95.5% and 73.8%, respectively. • ABCA12 and PRSS1 were identified as potential biomarkers in OMLDT patients

Amines in epoxy hardeners are significant causes of occupational allergic contact dermatitis among workers who use epoxy resin systems. To describe a novel group of contact allergens: N-(2-phenylethyl) derivatives of the reactive amine 1,3-benzenedimethanamine (1,3-BDMA). We describe the clinical examinations and exposure of 6 patients with occupational contact allergy to derivatives of 1,3-BDMA. Of the 6 patients, 4 were spray painters who used epoxy paints, 1 was a floor layer who handled a variety of epoxy coatings, and 1 was a worker in epoxy hardener manufacture. We were able to confirm exposure to epoxy hardeners that contained derivatives of 1,3-BDMA in 5 of the 6 sensitized patients. Despite the close structural resemblance between derivatives of 1,3-BDMA and m-xylylenediamine (MXDA), only 3 patients reacted positively to MXDA. Concomitant contact allergy to diglycidyl ether of bisphenol A resin was seen in 2 of the 6 patients. Because of the lack of a commercially available patch test substance, the diagnosis of contact allergy to derivatives of 1,3-BDMA requires patch testing with either the epoxy hardener product or a hardener ingredient that contains the derivatives of 1,3-BDMA. © 2016 John Wiley & Sons A/S.

Allergic contact dermatitis can induce an atopic dermatitis-like phenotype, and thus, flexural dermatitis cannot be assumed as atopic without further testing. Patch testing should at least be considered in cases of chronic or recurrent eczema regardless of the working diagnosis.

[Individual prevention of occupational contact dermatitis: protective gloves and skin protection recommendations as part of the patient management scheme by the public statutory employers' liability insurance].

The dermatologist's procedure is a pivotal tool for early recognition of occupational contact dermatitis (OCD), for reporting OCD cases to the statutory accident insurance and for treating the diseases. The employer is in charge of implementing skin protection measures at the workplace. However, in terms of an individual prevention approach it may be necessary to propose targeted skin protection recommendations in specific patient cases. The patient's own skin protection behavior significantly contributes to regenerating and maintaining healthy skin. This behavior includes the use of occupational skin products, and in particular the correct use of appropriately selected protective gloves. Protective gloves are the most important personal protective measure in the prevention of OCD. Prevention services, occupational health and safety specialists, occupational physicians and centers specialized in occupational dermatology can support the identification of suitable protective measures. Nowadays, suitable protective gloves exist for (almost) every occupational activity and exposure. However, improper use in practice can become a risk factor by itself for the skin (e. g., incorrectly used gloves). Therefore, it is of utmost importance to identify application errors, to educate patients in terms of skin protection and to motivate them to perform an appropriate skin protection behavior. With particular focus on protective gloves, this article gives an overview of various types, materials and potentially glove-related allergens, presents strategies for reducing occlusion effects and discusses some typical application errors and solutions.

Occupational skin diseases are common. The occurrence of occupational skin diseases represents a failure of primary prevention strategies that may include the use of personal protective equipment, most commonly gloves. The objective of this study was to describe current glove use and education practices related to gloves in workers being assessed for possible work-related hand dermatitis. Participants included consecutive patients being assessed for possible work-related hand dermatitis. A self-administered questionnaire obtained information on demographics, workplace characteristics and exposures, glove use, and education regarding gloves. Ninety percent of the 105 participants reported using gloves. Only 44% had received training related to glove use in the workplace. Major gaps in training content included skin care when using gloves, warning signs of skin problems, and glove size. If the worker indicated no glove training received, the majority reported they would have used gloves if such training was provided. Although the majority of workers being assessed wore gloves, the minority had received training related to glove use. Particular gaps in training content were identified. Those who had not received training noted they would likely have used gloves if training had been provided.

Contact dermatitis and patch testing for the allergist.

Contact dermatitis (CD) is a common disease seen by allergists. Although underutilized, patch testing (PT) remains the gold standard in the diagnosis of allergic CD. It is not difficult to perform, however, the interpretation of the PT, proper classification of the results and determination of their relevance, need an appropriate level of expertise. The objective of this article is to provide a review of CD and its key allergens and provide updates and recommendations for the practicing allergist. Through the use of various scientific search engines (e.g., PubMed and Medline) we reviewed literature on CD, PT, key allergens, occupational dermatitis and treatment. Studies on CD, important allergens, and PT were considered. Contact induced dermatitis may be due to allergic CD, irritant CD, systemic CD, contact urticaria and protein CD. Key allergens include metals (nickel, gold), topical medicaments (topical corticosteroids), and cosmetics and personal care products (fragrances and preservatives such as methyl- and methylchloro-isothiazolinone). Present relevance of a positive PT is the combination of definite, probable, and possible relevance and should be correlated with the patient's history and physical examination. Treatment of allergic CD includes identification of relevant allergens, patient education, avoidance and provision of alternative products the patient can use. CD is a common inflammatory skin disease and should be suspected in patients presenting acute, subacute or chronic dermatitis. The gold standard for diagnosing allergic CD is PT. This article provides practical recommendations for the diagnosis and management of CD commonly seen by the allergist in their practice. Copyright © 2018. Published by Elsevier Inc.

Follicular contact dermatitis revisited: A review emphasizing neomycin-associated follicular contact dermatitis

Science.gov (United States)

Cohen, Philip R

2014-01-01

Follicular contact dermatitis clinically presents as individual papules that include a central hair follicle. Pathologic features involve the follicle and the surrounding dermis: spongiosis and vesicle formation of the follicular epithelium associated with perifollicular and perivascular lymphocytic inflammation. Using the PubMed database, an extensive literature search was performed on follicular contact dermatitis and neomycin. Relevant papers were reviewed and the clinical and pathologic features, the associated chemicals (including a more detailed description of neomycin), the hypothesized pathogenesis, and the management of follicular contact dermatitis were described. Several agents-either as allergens or irritants-have been reported to elicit follicular contact dermatitis. Several hypotheses have been suggested for the selective involvement of the follicles in follicular contact dermatitis: patient allergenicity, characteristics of the agent, vehicle containing the agent, application of the agent, and external factors. The differential diagnosis of follicular contact dermatitis includes not only recurrent infundibulofolliculitis, but also drug eruption, mite infestation, viral infection, and dermatoses that affect hair follicles. The primary therapeutic intervention for follicular contact dermatitis is withdrawal of the causative agent; treatment with a topical corticosteroid preparation may also promote resolution of the dermatitis. In conclusion, follicular contact dermatitis may be secondary to allergens or irritants; topical antibiotics, including neomycin, may cause this condition. Several factors may account for the selective involvement of the hair follicle in this condition. Treatment of the dermatitis requires withdrawal of the associated topical agent; in addition, topical corticosteroids may be helpful to promote resolution of lesions. PMID:25516854

Perianal complaints are often consulted in dermatology clinics, and in many cases, a conclusive diagnosis is not easily made. The aim of this study was to study and identify the epidemiological, clinical, and contact allergy features of patients with perianal dermatitis who attended at a contact dermatitis unit in a tertiary hospital in Spain. Adult patients with long-lasting (>4 weeks) perianal dermatitis were recruited during the past 10 years for investigation and follow-up. Every patient underwent a diagnostic workup consisting of dermatological exploration and patch tests with the standard and specific series, as well as the patients' own products. General surgical exploration was also performed in some patients. One hundred twenty-four patients were included. The MOAHLFA index was as follows: 43.5, 0, 4.8, 11.3, 1.6, 8.1, and 75. The main final diagnoses were allergic contact dermatitis (32.3%), psoriasis (24.2%), irritant contact dermatitis (17.7%), and lichen simplex (neurodermatitis) (10%). Eighty-one patients (66.1%) showed 1 or more positive reactions, and in 52 patients (43%), positive reactions relevant to the present disease were found. Contact allergy in patients with long-lasting perianal complaints is frequent. It is mandatory for these patients to be referred to a dermatologist for an adequate evaluation and patch testing. Methylchloroisothiazolinone/methylisothiazolinone seems as the most common allergen implicated in perianal contact dermatitis.

Workplace training may help to prevent contact dermatitis, a common work-related disease. Information on the characteristics of existing workplace training programs and worker perceptions of this training is limited. Fourteen workers with suspected occupational contact dermatitis participated in one-on-one, semi-structured interviews. An inductive thematic analysis approach was used to identify interview themes. Workers expressed a desire for hands-on training with content relevant to their job tasks, favored training from supervisors who had practical experience, and were conflicted about employer motivations for providing training. Few workers had received training on skin protection. In many cases, the training workers had received differed greatly from their desired training. Although, workers with contact dermatitis describe having received workplace training, some question its value and effectiveness. This perspective may be attributed not only to the content and methods of training but also the health and safety culture of the workplace. Am. J. Ind.

Background Sites of dermatitis in larger series of contact allergic patients are rarely reported. Increased risk of polysensitization has been linked only to stasis dermatitis and leg ulcers. However, a large proportion of polysensitized individuals may have dermatitis in other skin areas...... was the least frequent skin area affected with dermatitis. Dermatitis on the hands/wrists [odds ratio (OR) 1.58], in the armpits (OR 1.56) and on the back (OR 1.91) was positively associated with polysensitization. The hands were the only skin area with dermatitis which maintained the association...

Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are increasingly popular. We describe here 3 patients with contact allergy to acrylates in artificial sculptured nails. Patch tests were performed with the Portuguese baseline series of contact allergens and an extended series of acrylates were applied. In particular, we tested three female patients with allergic contact dermatitis from sculptured acrylic nails. Two of these patients were both customers and also technical nail beauticians. Two patients developed periungual eczema; one presented only with face and eyelid dermatitis had no other lesions. The tests showed positive reaction to 2-hydroxyethylmethacrylate (2-HEMA) and 2-hydroxypropylmethacrylate (2-HPMA) in all the three patients. Our cases demonstrate the variety of clinical presentations of allergic contact dermatitis from acrylic sculptured nails. They show the need to warn patients of persistent and sometimes permanent side effects of these products. They also emphasize the importance of cosmetic ingredient labeling. PMID:25386316

2013-01-01

Paederus dermatitis is a distinct variant of acute irritant contact dermatitis caused by mucocutaneous contact with the specific toxin of an insect belonging to the genus Paederus. It is characterized by the sudden onset of erythema and vesiculobullous lesions on exposed skin, with special predilection for the periorbital region. Paederus species have been mostly identified in Africa, Asia, Australia, and Central/South America. We report a 51-year-old woman who experienced 4 recurrences of periorbital erythema and edema in the previous year. No consistent etiology could be established at the beginning. Only after taking a detailed medical history was it discovered that 1 year before our examination, the patient had traveled to Kenya, where she had experienced contact with the insect. This fact led us to the diagnosis of Paederus dermatitis. After appropriate treatment, a complete regression was observed over a 3-week period.

Contact dermatitis is an umbrella term that describes the skin's reaction to contacted noxious or allergenic substances. The two main categories of contact dermatitis are irritant type and allergic type. This review discusses the signs, symptoms, causes, and complications of contact dermatitis. It addresses the testing, treatment, and prevention of contact dermatitis. Proper management of contact dermatitis includes avoidance measures for susceptible children. Implementation of a nickel directive (regulating the use of nickel in jewelry and other products that come into contact with the skin) could further reduce exposure to the most common allergens in the pediatric population.

Patch Test Negative Generalized Dermatitis.

Science.gov (United States)

Spiker, Alison; Mowad, Christen

2016-01-01

Allergic contact dermatitis is a common condition in dermatology. Patch testing is the criterion standard for diagnosis. However, dermatitis is not always caused by an allergen, and patch testing does not identify a culprit in every patient. Generalized dermatitis, defined as eczematous dermatitis affecting greater than 3 body sites, is often encountered in dermatology practice, especially patch test referral centers. Management for patients with generalized dermatitis who are patch test negative is challenging. The purpose of this article is to outline an approach to this challenging scenario and summarize the paucity of existing literature on patch test negative generalized dermatitis.

The healthcare sector ranked in second place among economic sectors in the Czech Republic, with about 11.4 % of all occupational diseases in 2009. Skin diseases constituted about 20 % of all occupational diseases. The aim of this study was to analyze the causes and trends in allergic and irritant-induced skin diseases in the healthcare sector. The data concerning occupational skin diseases (Chapter IV of the Czech List of Occupational Diseases, non-infectious skin illnesses) in the healthcare sector were analyzed from the Czech National Registry of Occupational Diseases from 1997 until 2009. The trends in the total counts and most frequent causes were evaluated. During the past 13 years, a total of 545 skin diseases were acknowledged in healthcare workers. Allergic contact dermatitis was diagnosed in 464 (85 %), irritant contact dermatitis in 71 (13 %) and contact urticaria in 10 subjects (2 %). Ninety-five percent of the patients were females. The overall incidence in individual years varied between 1.0 and 2.9 cases per 10,000 full-time employees per year. Disinfectants were the most frequent chemical agents causing more than one third of all allergic skin diseases (38 %), followed by rubber components (32 %) and cleaning agents (10 %). A general downward trend of diagnosed cases of occupational skin diseases in heath care workers in the Czech Republic over the past 13 years was demonstrated.

Noneczematous Contact Dermatitis

Science.gov (United States)

Foti, Caterina; Vestita, Michelangelo; Angelini, Gianni

2013-01-01

Irritant or allergic contact dermatitis usually presents as an eczematous process, clinically characterized by erythematoedematovesicous lesions with intense itching in the acute phase. Such manifestations become erythematous-scaly as the condition progresses to the subacute phase and papular-hyperkeratotic in the chronic phase. Not infrequently, however, contact dermatitis presents with noneczematous features. The reasons underlying this clinical polymorphism lie in the different noxae and contact modalities, as well as in the individual susceptibility and the various targeted cutaneous structures. The most represented forms of non-eczematous contact dermatitis include the erythema multiforme-like, the purpuric, the lichenoid, and the pigmented kinds. These clinical entities must obviously be discerned from the corresponding “pure” dermatitis, which are not associated with contact with exogenous agents. PMID:24109520

Airborne allergic contact dermatitis caused by paints containing isothiazolinones has been recognized as a health hazard. To collect epidemiological, clinical and patch test data on airborne allergic contact dermatitis caused by isothiazolinone-containing paints in France and Belgium. A descriptive, retrospective study was initiated by the Dermatology and Allergy Group of the French Society of Dermatology, including methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI)- and/or MI-sensitized patients who developed airborne allergic contact dermatitis following exposure to isothiazolinone-containing paint. Forty-four cases were identified, with mostly non-occupational exposure (79.5%). Of the patients, 22.5% of also had mucosal symptoms. In several cases, the dermatitis required systemic corticosteroids (27.3%), hospitalization (9.1%), and/or sick leave (20.5%). A median delay of 5.5 weeks was necessary to enable patients to enter a freshly painted room without a flare-up of their dermatitis. Approximately one-fifth of the patients knew that they were allergic to MI and/or MCI/MI before the exposure to paints occurred. Our series confirms that airborne allergic contact dermatitis caused by paints containing isothiazolinones is not rare, and may be severe and long-lasting. Better regulation of isothiazolinone concentrations in paints, and their adequate labelling, is urgently needed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Stressors in Atopic Dermatitis.

Science.gov (United States)

Barilla, Steven; Felix, Kayla; Jorizzo, Joseph L

2017-01-01

As with other inflammatory skin disorders, atopic dermatitis has a tendency to cause stress and also be exacerbated by it. Patients with atopic dermatitis have several disease-associated stressors, some of which include physical discomfort due to itching and altered appearance due to flare-ups. These stressors have been shown to effect patients psychosocially by altering sleep patterns, decreasing self-esteem and interfering with interpersonal relationships. In combination with its direct effect on patients, atopic dermatitis also causes stress for parents and caregivers. Studies suggest that atopic dermatitis is strongly correlated with co-sleeping habits, which can negatively impact the health and mood of parents or caregivers. It has also been reported to interfere with the formation of a strong mother-child relationship. In order to optimize treatment for patients with atopic dermatitis, it is important to note the impact that it has on quality of life. By implementing patient counseling, sleep-targeted therapies, and the use of quality of life (QoL) indices, atopic dermatitis patients and caregivers have the potential to experience greater satisfaction with treatment.

Occupational diseases caused by ionizing radiation in medical personnel in the Czech Republic in 1974-1997

International Nuclear Information System (INIS)

Fenclova, Z.; Pelclova, D.; Lebedova, J.; Urban, P.; Petrova, K.

1999-01-01

During 1974-1997, the incidence of occupational diseases caused by ionizing radiation in medical personnel was low (0 to 0.4 % of all notified occupational diseases, with a decreasing tendency over this period of time). There have been 136 cases of occupational diseases caused by ionizing radiation; in this, 111 cases occurred in the health care sector. Radiation dermatitis was the most frequent disease (88 cases). Physicians constituted the most affected occupational group in the 1991 - 1997 period. The age of the affected physicians lay in the range of 45 to 77. The personnel affected by radiation dermatitis had the shortest (5 years) as well as longest (46 years) exposure. Lung cancer caused by radioactive chemicals was only diagnosed in two persons in the health care sector during 1974 - 1997. It should be noted that the occupational diseases were caused by elevated exposures experienced in previous years or developed as a consequence of radiation accidents. In view of the present advanced level of protection against ionizing radiation, the numbers of this kind of disease is not expected to grow any further

EU legislation has reduced the epidemic of nickel contact allergy affecting the consumer, and shifted the focus towards occupational exposure. The acid wipe sampling technique was developed to quantitatively determine skin exposure to metals. To assess the clinical usefulness of the acid wipe sampling technique as part of the diagnostic investigation for occupational nickel allergy-associated hand dermatitis. Six patients with vesicular dermatitis on the hands were included. Acid wipe sampling of skin and patch testing with a nickel sulfate dilution series were performed. Nickel was detected in all samples from the hands. In all patients, the nickel content on the hands was higher than on the non-exposed control area. Occupational exposure to nickel-releasing items raised the nickel content on exposed skin as compared with a non-exposed control site. Nickel-reducing measures led to complete symptom relief in all cases. In cases of a positive nickel patch test reaction and hand eczema, patients should perform the dimethylglyoxime (DMG) test on metallic items at home and at work. The acid wipe sampling technique is useful for the diagnosis of occupational hand eczema following screening with the inexpensive DMG test. © 2010 John Wiley & Sons A/S.

Preventing Occupational Skin Disease: A Review of Training Programs.

Science.gov (United States)

Zack, Bethany; Arrandale, Victoria H; Holness, D Linn

Occupational contact dermatitis (OCD) is a common occupational disease that impacts a variety of worker groups. Skin protection and disease prevention training programs have shown promise for improving prevention practices and reducing the incidence of OCD. This review details the features of training programs for primary prevention of OCD and identifies gaps in the literature. Twelve studies were identified for in-depth review: many studies included wet workers employed in health care, hairdressing, cleaning, and food preparation; 1 program featured manufacturing workers. Few programs provided content on allergic contact dermatitis, and only 1 was evaluated for long-term effectiveness. Effective programs were similar in content, delivery method, and timing and were characterized by industry specificity, multimodal learning, participatory elements, skin care resource provision, repeated sessions, and management engagement. Long-term effectiveness, generalizability beyond OCD, workplace health and safety culture impact, and translation of programs in the North American context represent areas for future research.

Construction workers handle cement which has constituents to produce both irritant contact dermatitis and corrosive effects (from alkaline ingredients, such as lime) and sensitization, leading to allergic contact dermatitis (from ingredients, such as chromium). The present study has been carried out among unorganized construction workers to find the prevalence of skin problems. The present cross-sectional study was conducted in 92 construction workers of Ahmedabad and Vadodara. All the workers were subjected to clinical examination after collection of information regarding demographic characteristics, occupational characteristics and clinical history on a predesigned proforma. Of them, 47.8% had morbid skin conditions. Frictional callosities in palm were observed in 18 (19.6%) subjects while 4 (4.3%) subjects had contact dermatitis. Other conditions included dry, fissured and scaly skin, infectious skin lesion, tinea cruris, lesion and ulcers on hands and/or soles. The skin conditions were common in the age group of 20-25 years, males, those having ≥1 year exposure and those working for longer hours. Half of the workers not using personal protective equipment had reported skin-related symptoms.

Chemicals used for the manufacturing of rubber are known causes of allergic contact dermatitis on the hands. Recent European studies have suggested a decrease in thiuram contact allergy. Moreover, while an association with hand dermatitis is well established, we have recently observed several clinical cases with allergic facial dermatitis to rubber. To evaluate temporal trends of contact allergy to rubber accelerators from the European baseline series in a tertiary patch test clinic in Denmark, and examine associations with anatomical locations of dermatitis. Patch test and clinical data collected in a Danish tertiary dermatology clinic in Gentofte, Herlev, Copenhagen between 1 January 2005 and 31 December 2014 were analysed. The following rubber accelerators or mixtures in petrolatum from the European baseline patch test series were included: thiuram mix 1.0%, mercaptobenzothiazole 2.0% and mercapto mix 1.0%. The overall prevalence of contact allergy to rubber accelerators was 3.1% with no significant change during the study period (P trend = 0.667). Contact allergy to thiuram mix was the most prevalent and was significantly associated with occupational contact dermatitis, hand dermatitis, age >40 years and facial dermatitis in adjusted binary logistic regression analysis. Current clinical relevance of contact allergy to thiuram mix was 59.3%. Patients with contact allergy to mercapto mix and mercaptobenzothiazole had a concomitant reaction to thiuram mix in 35.2% (19/54) and 35.4% (17/48) of the cases respectively. Contact allergy to rubber accelerators remains prevalent. Clinicians should be aware of the hitherto unexplored clinical association with facial dermatitis. © 2016 European Academy of Dermatology and Venereology.

Both active and inactive ingredients in sunscreen may cause contact dermatitis. This study aimed to describe allergens associated with a sunscreen source. A cross-sectional analysis of patients patch tested by the North American Contact Dermatitis Group between 2001 and 2010 was performed. Of 23,908 patients patch tested, 219 (0.9%) had sunscreen coded as an allergen source. Patients who were male, with occupational dermatitis, or older (older than 40 years) had significantly lower rates of allergic reactions to sunscreens; the most commonly affected areas were the face and exposed sites (P Contact Dermatitis Group screening series of 65 to 70 allergens. A supplemental antigen series is important in detecting allergy to sunscreens.

Stoma dermatitis: prevalent but often overlooked.

2010-01-01

Peristomal dermatoses commonly afflict the area around stoma openings in ostomy patients. These complications, however, are often unreported by patients and remain untreated for years, thus affecting maintenance and recovery from the surgery. These dermatoses can have chemical, mechanical, irritant, bacterial, immunologic, or disease-related etiologies. Examples of common forms of dermatitis that occur peristomally include fecal or urine irritant contact dermatitis, chronic papillomatous dermatitis, mechanical dermatitis, and allergic contact dermatitis. This article summarizes various skin irritations that can occur after an ostomy and also reviews previously published reports of peristomal allergic contact dermatitis. In addition, the clinical importance of identifying these dermatoses (most important, their effects on the patient's quality of life), risk factors for the skin irritations, the importance of patch testing, treatment of stoma dermatitis, and the importance of patient education and patient-doctor communication are also discussed.

Healthcare workers (HCWs) are at risk of developing occupational skin disease (OSD). To ascertain the causes of OSD in Australian HCWs in a tertiary referral clinic. A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne from 1993 to 2014. Of 685 HCWs assessed in the clinic over a period of 22 years, 555 (81.0%) were diagnosed with OSD. The most common diagnosis was irritant contact dermatitis (ICD) (79.1%), followed by allergic contact dermatitis (ACD) (49.7%). Natural rubber latex allergy was also relatively frequent (13.0%). The major substances causing ACD were rubber glove chemicals (thiuram mix and tetraethylthiuram disulfide), preservatives (formaldehyde, formaldehyde releasers, and isothiazolinones), excipients in hand cleansers, which are hard-to-avoid weak allergens, and antiseptics. ACD caused by commercial hand cleansers occurred more frequently than ACD caused by alcohol-based hand rubs (ABHRs). Occupational ICD was mostly caused by water/wet work and hand cleansers, and environmental irritants such as heat and sweating. Understanding the causes of OSD in HCWs is important in order to develop strategies for prevention. We suggest that skin care advice should be incorporated into hand hygiene education. The use of ABHRs should be encouraged, weak allergens in skin cleansers should be substituted, and accelerator-free gloves should be recommended for HCWs with OSD. © 2016 John Wiley & Sons A/S.

Geriatric nurses (GN) have a high risk of occupational contact dermatitis (OCD), with chronic irritant contact dermatitis predominating. However, allergic contact dermatitis is an important issue as well. Little is known whether the relevant occupational allergen spectrum reported in the 1990s, including fragrances, preservatives, rubber chemicals and ingredients of surface disinfectants to be the most common sensitizers in GN, is still valid. To monitor the current allergen spectrum in GN with OCD and verify the validity of the patch test recommendations (baseline-, preservative-, ointment base-, rubber-, disinfectant, series and fragrances) in GN with suspected OCD given by the German Contact Dermatitis Research Group (DKG). Retrospective analysis of IVDK data (2005-2014) of 743 female GN with OCD, in comparison to 695 GN without OCD. GN with OCD reacted significantly more frequently to both fragrance mixes, hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC), thiuram mix, zinc diethyldithiocarbamate and mercaptobenzothiazole than GN without OCD. Reactions to MDBGN, methylchloroisothiazolinone/methylisothiazolinone and oil of turpentine occurred substantially, but not significantly more frequently among GN with OCD. The latter may be due to former use of a special alcoholic liniment in geriatric care. Among material from the patients' workplaces, tetrazepam was a frequent allergen, due to dust exposure from pill crushing. Furthermore, occupationally used protective gloves, body care products as well as surface disinfectants were often tested positively. The general allergen spectrum in GN with OCD is unchanged, so the DKG patch test recommendations are still valid. Prevention of occupational sensitization should focus on fragrance-free hygiene and body care products, usage of accelerator-free protective gloves and avoidance of drug dust exposure. © 2016 European Academy of Dermatology and Venereology.

Dermatitis palmaris sicca (DPS) is a common dry-fissured palmar dermatitis in Asian women. It may be an irritant contact dermatitis, but the immunophenotype of the cells in its infiltrate is unknown. The aim of this study was to evaluate the role of inflammatory cells in the pathogenesis of DPS. Patch testing was done in 68 patients with DPS, 87 subjects with hand eczema, and 31 healthy subjects. Immunophenotyping of cutaneous inflammatory cells was performed in 8 patients with DPS, 10 subjects with hand eczema, and 8 healthy individuals. Positive patch rates were higher in patients with DPS and those with hand eczema compared with healthy controls, but strong positive (++ or +++) reactions in DPS were fewer compared with hand eczema. Density of CD3, CD4, CD8, and CD68 cells in skin lesions of DPS and hand eczema was significantly higher than that in normal skin. Sparse CD20 cells were present only in hand eczema. Compared with hand eczema, the number of CD3, CD8, CD68, and dermal CD1a cells decreased, but epidermal CD1a cells and CD4/CD8 ratio increased in DPS. The absolute lack of CD20 cells and relative scarcity of dermal CD8 and CD1a cells in skin lesions might be insufficient to induce contact hypersensitivity, so DPS may be an irritant but not allergic contact dermatitis.

Studies on occupational skin diseases in workers of the automotive industry are few. To investigate the prevalence of occupational skin diseases in workers of the automotive industry. Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakır were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

Occupational irritant contact dermatitis (ICD) affecting the hands is a common and difficult-to-manage condition. Occupations that necessitate contact with harsh chemicals, use of alcohol-based disinfectants, and frequent hand washing elevate the risk of ICD. Management strategies that do not adequately prevent accumulated damage and repair skin, can develop into chronic dermatoses which negatively impact work productivity and quality of life. A 2-step skin-care regimen (Excipial Daily Protection Hand Cream (EP) and Excipial Rapid Repair Hand Cream (ER), Galderma Laboratories, L.P.) has been developed as a daily-use management strategy to protect and repair vulnerable hands. The protective barrier cream is formulated with aluminum chlorohydrate and designed for pre-exposure application to enhance the skin's natural protective barrier and minimize excessive moisture while wearing protective gloves. The repair cream, a lipid-rich formulation, is intended for post-exposure application to rehydrate and facilitate the skin's natural healing process. The results of 3 clinical studies highlighted in this review demonstrate how the use of a 2-step skin-care regimen offers a greater protective effect against ICD than the use of barrier cream alone, and also how the formulation of the barrier cream used in these studies helps minimize the occlusion effect caused by gloves and does not interfere with the antibacterial efficacy of an alcohol-based hand sanitizer. This 2-step skin-care regimen is effectively designed to manage and minimize the risk of ICD development in a variety of patients and provides clinicians an additional tool for helping patients manage ICD.

Fiddler's neck: Chin rest-associated irritant contact dermatitis and allergic contact dermatitis in a violin player.

Science.gov (United States)

Caero, Jennifer E; Cohen, Philip R

2012-09-15

Fiddler's neck refers to an irritant contact dermatitis on the submandibular neck of violin and viola players and an allergic contact dermatitis to nickel from the bracket attaching the violin to the chin rest on the violinist's supraclavicular neck. A 26-year-old woman developed submandibular and supraclavicular left neck lesions corresponding to the locations of the chin rest and bracket that was attached to her violin that held it against her neck when she played. Substitution of a composite chin rest, which did not contain nickel, and the short-term application of a low potency topical corticosteroid cream, resulted in complete resolution of the allergic contact dermatitis supraclavicular neck lesion. The irritant contact dermatitis submandibular neck lesion persisted. In conclusion, violin players are predisposed to developing irritant contact dermatitis or allergic contact dermatitis from the chin rest. We respectfully suggest that the submandibular neck lesions from contact with the chin rest be referred to as 'fiddler's neck - type 1,' whereas the supraclavicular neck lesions resulting from contact of the bracket holding the chin rest in place be called 'fiddler's neck - type 2.' A composite chin rest should be considered in patients with a preceding history of allergic contact dermatitis to nickel.

Foot dermatitis is a widespread condition, affecting men and women of all ages. Because of the location, this condition may present as a debilitating problem to those who have it. Allergic contact dermatitis involving the feet is frequently due to shoes or socks. The allergens that cause shoe dermatitis can be found in any constituent of footwear, including rubber, adhesives, leather, dyes, metals, and medicaments. The goal of treatment is to identify and minimize contact with the offending allergen(s). The lack of product information released from shoe manufacturers and the continually changing trends in footwear present a challenge in treating this condition. The aim of this study is to review the current literature on allergic contact shoe dermatitis; clinical presentation, allergens, patch testing, and management will be discussed. PubMed and MEDLINE databases were used for the search, with a focus on literature updates from the last 15 years.

Job-related hand dermatitis heads up the list of reported occupational diseases. So-called skin products - understood to mean protective creams, skin cleansers and skin care products - are used for the primary and secondary prevention of job- related hand dermatitis. In the interests of evidence-based medicine, the only preventive measures and/or occupational skin products that should be used are those whose potential uses and efficacy are underpinned by scientific research. To this end, the Arbeitsgemeinschaft für Berufs- und Umweltdermatologie e.V. (Working Group for Occupational and Environmental Dermatology, ABD) of the DDG (German Dermatological Society) and the Deutsche Gesellschaft für Arbeits- und Umweltmedizin (German Society for Occupational and Environmental Medicine, DGAUM) have summed up the latest scientific findings and recommendations in the updated guideline. The benefit of the combined application of protective creams and skin care products in the primary and secondary prevention of work-related contact dermatitis has been widely confirmed by recent clinical-epidemiological studies. The guideline clearly explains the necessity of demonstrating the efficacy of protective creams and cleansing products by means of in vivo methods in the sense of repetitive applications. Transferable standardised testing systems designed to examine the irritation potential and thus the compatibility of occupational skin cleansers and the reduction of irritation by protective skin creams have now been developed and validated by multicentre studies for skin protection creams and cleansers. The status of the current assessment of the safety of occupational skin products is also summarised. © 2015 The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

Acrylates, the 2012 American Contact Dermatitis Society allergen of the year, are found in a range of products including the absorbent materials within feminine hygiene pads. When fully polymerized, acrylates are nonimmunogenic; however, if not completely cured, the monomers can be potent allergens.A 28-year-old woman is presented, who had her teeth varnished with Isodan (Septodont, Saint-Maur-des-Fossés, France) containing HEMA (2-hydroxyethyl methacrylate) with no initial reaction. Approximately 1 month later, the patient developed a genital dermatitis secondary to her feminine hygiene pads. The initial reaction resolved, but 5 months later, the patient developed a systemic contact dermatitis after receiving a second varnishing.The patient was dramatically patch test positive to many acrylates. This case demonstrates a reaction to likely unpolymerized acrylates within a feminine hygiene pad, as well as broad cross-reactivity or cosensitivity to acrylates, and possibly a systemic contact dermatitis with systemic re-exposure to unpolymerized acrylates.

The terms "palisaded neutrophilic and granulomatous dermatitis," "interstitial granulomatous dermatitis," and the subset "interstitial granulomatous drug reaction" are a source of confusion. There exists substantial overlap among the entities with few strict distinguishing features. We review the literature and highlight areas of distinction and overlap, and propose a streamlined diagnostic workup for patients presenting with this cutaneous reaction pattern. Because the systemic disease associations and requisite workup are similar, and the etiopathogenesis is poorly understood but likely similar among these entities, we propose the simplified unifying term "reactive granulomatous dermatitis" to encompass these entities.

Occupational allergy among florists and people who work in cut flower production of Alstroemeria cultivars (Peruvian lily or Inca lily) has been previously reported. The allergen involved in sensitization is tulipalin A (alpha-methylene-gamma-butyrolactone). We describe the case of a 65-year-old woman who developed severe dermatitis on her right thumb, index and middle fingers and less severe dermatitis on her left palm and front of forearm with occasional itching of the neck and face after taking up home gardening activities, including cutting flowers such as Alstroemeria. The patient and three healthy individuals were submitted to epicutaneous tests with the European standard series, the plant series, and stem portions of three suspected ornamental plants (Alstroemeria, Lilium and Zantedeschia), garlic, and onion. Patch tests performed in our patient, revealed an extreme reaction (+ + +) to Alstroemeria and alpha-methylene-gamma-butyrolactone, a strong reaction (+ +) to propolis and wood tar mix, a weak reaction (+) to balsam of Peru, an irritant reaction to garlic and negative results to diallyl disulfide and the other components investigated. Patch tests performed in the healthy individuals revealed negative. We stress the importance of Alstroemeria as a cause of allergic contact dermatitis not only in workers involved in the flower trade, but also in other people that come into contact with this plant in their leisure activities.

Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction. The gold standard for diagnosis is patch testing. The prevalence of positive patch tests in referred patients with suspected ACD ranges from 27 to 95.6%. The relationship between ACD and atopic dermatitis (AD) is complicated with conflicting reports of prevalence in the literature; however, in a patient with dermatitis not responding to traditional therapies, or with new areas of involvement, ACD should be considered as part of the work-up.

To provide information from a literature review about the prevention, recognition, and treatment for contact dermatitis. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Identify signs and symptoms of and diagnostic measures for contact dermatitis.2. Identify causes and risks for contact dermatitis.3. Select appropriate treatment for contact dermatitis and its prevention. Contact dermatitis to wound care products is a common, often neglected problem. A review was conducted to identify articles relevant to contact dermatitis.A PubMed English-language literature review was conducted for appropriate articles published between January 2000 and December 2015.Contact dermatitis is both irritant (80% of cases) or allergic (20% of cases). Frequent use of potential contact allergens and impaired barrier function of the skin can lead to rising sensitization in patients with chronic wounds. Common known allergens to avoid in wound care patients include fragrances, colophony, lanolin, and topical antibiotics.Clinicians should be cognizant of the allergens in wound care products and the potential for sensitization. All medical devices, including wound dressings, adhesives, and bandages, should be labeled with their complete ingredients, and manufacturers should be encouraged to remove common allergens from wound care products, including topical creams, ointments, and dressings.

Allergic contact dermatitis is considered one of the most common causes of eyelid dermatitis. In addition to metals and topical antibiotics, fragrances have emerged as a leading source of contact allergy for individuals with this condition. The objective of this study was to determine the added benefit of including a fragrance tray when patch testing patients presenting with eyelid dermatitis. During a 4.5-year period, all patients with suspected allergic contact dermatitis involving the eyelids were patch tested with both standard and fragrance trays. One hundred consecutive patients with eyelid dermatitis were patch tested. Of these patients, 42 (42%) tested positive for 1 or more allergens within the fragrance series. Of these patients, 15 (36%) had no fragrance markers detected on the standard series, and these allergens would therefore have been missed had fragrance series testing not been performed. Overall, fragrance markers within the standard series detected 73.2% (41/56) of cases of fragrance allergy. Our results suggest that there may be a significant benefit to fragrance series testing in patients with eyelid dermatitis. Fragrance tray inclusion in this population may identify additional cases of fragrance allergy that are missed by the standard series.

Patch testing is an important diagnostic tool for determination of substances responsible for allergic contact dermatitis. This study reports the North American Contact Dermatitis Group (NACDG) patch testing results from January 1, 2009, to December 31, 2010. At 12 centers in North America, patients were tested in a standardized manner with a screening series of 70 allergens. Data were manually verified and entered into a central database. Descriptive frequencies were calculated, and trends were analyzed using χ2 statistics. A total of 4308 patients were tested. Of these, 2614 (60.7%) had at least 1 positive reaction, and 2284 (46.3%) were ultimately determined to have a primary diagnosis of allergic contact dermatitis. Four hundred twenty-seven (9.9%) patients had occupationally related skin disease. There were 6855 positive allergic reactions. As compared with the previous reporting period (2007-2008), the positive reaction rates statistically decreased for 20 allergens (nickel, neomycin, Myroxylon pereirae, cobalt, formaldehyde, quaternium 15, methydibromoglutaronitrile/phenoxyethanol, methylchlorisothiazolinone/methylisothiazolinone, potassium dichromate, diazolidinyl urea, propolis, dimethylol dimethylhydantoin, 2-bromo-2-nitro-1,3-propanediol, methyl methacrylate, ethyl acrylate, glyceryl thioglycolate, dibucaine, amidoamine, clobetasol, and dimethyloldihydroxyethyleneurea; P < 0.05) and statistically increased for 4 allergens (fragrance mix II, iodopropynyl butylcarbamate, propylene glycol, and benzocaine; P < 0.05). Approximately one quarter of tested patients had at least 1 relevant allergic reaction to a non-NACDG allergen. Hypothetically, approximately one quarter of reactions detected by NACDG allergens would have been missed by TRUE TEST (SmartPractice Denmark, Hillerød, Denmark). These results affirm the value of patch testing with many allergens.

Full Text Available BACKGROUND: Contact dermatitis is one of the common work-related dermatoses. Among bricklayers, cement can cause both allergic contact dermatitis and primary contact irritative dermatitis. The personal protective equipment (rubber gloves may favor the development of allergic contact dermatitis. OBJECTIVES: 1 to evaluate the frequency of allergic contact dermatitis among construction workers between January 2005 and December 2009; 2 to determine the major sensitizing agents in the study group; and 3 to compare the data obtained from the construction workers to that of a group of patients who were not construction workers. METHODS: A retrospective analysis of patch tests. Patients were separated into two groups: 1 bricklayers and 2 non-bricklayers. RESULTS: Of the 525 patch tests analyzed, 466 (90% were from non-bricklayers and 53 (10% from bricklayers. The hands were affected in 38 (61% of them. 13 patients (24% had irritative contact dermatitis and 40 (76% had allergic contact dermatitis. The group of construction workers had a high frequency of sensitization to cement, and 29 (54.7% had sensitization to rubber vulcanizing agents. 23 patients (43.4% had sensitization to both cement and rubber. CONCLUSIONS: Among the bricklayers the presence of allergic contact dermatitis to rubber and cement in the same patient is common and demonstrates the importance of the patch test.FUNDAMENTOS: A dermatite de contato é uma das dermatoses comumente relacionadas ao trabalho.

Magembe, Anna J; Davis, Mark D P; Richardson, Donna M

2009-01-01

Patch testing rarely is confounded by localized dermatitis induced in the area being tested (usually the back). Its occurrence renders the interpretation of patch tests impossible. To review our experience of the circumstances in which this phenomenon occurs during patch testing. We retrospectively reviewed patients with this phenomenon who underwent patch testing from January 1, 2002, through June 30, 2006. Of the 3,569 patients tested, 12 (0.34% [9 men and 3 women]) had development of this phenomenon. All patients previously had recent widespread dermatitis that was suppressed temporarily with topical corticosteroids and wet dressings at the time of patch testing. The period between control of the dermatitis and the initiation of patch testing was less than 1 week for all patients. Three patients (25%) had recently discontinued therapy with systemic corticosteroids (less than 1 week earlier). In patients with irritable skin either immediately after widespread dermatitis is controlled or after the cessation of systemic corticosteroid treatment, a flare of dermatitis induced by patch testing may render patch tests unreadable and therefore uninterpretable. To avoid this confounding occurrence, a waiting period between control of widespread dermatitis and initiation of patch testing is advised.

In Japan, allergic contact dermatitis caused by hair colouring agents is a considerable problem for those occupationally exposed and also for consumers. Over the last 20 years, p-phenylenediamine (PPD) has been a common allergen, with ∼7% positive patch test reactions. To investigate which ingredients caused allergic contact dermatitis related to hair dye and perming solutions in Japan, to assess whether PPD is suitable for screening for hair dye allergy, and to propose allergens for a Japanese hairdresser series. We selected 19 hair cosmetic allergens, including PPD, Bandrowski's base, cysteamine HCl, and ammonium thioglycolate. Altogether 203 patients (26 males and 177 females) with suspected contact allergy to hair colouring or perming solutions at 14 hospitals in Japan were included. The highest prevalence of positive reactions (35.1%) was for PPD. p-Methylaminophenol and o-aminophenol were often positive, both in the PPD-positive and in the PPD-negative patients. Moreover, cysteamine HCl often yielded positive test reactions. PPD is insufficient to diagnose contact allergy caused by to hair dyes. We recommend 13 allergens to be included in a Japanese hairdresser series. © 2017 The Authors. Contact Dermatitis published by John Wiley & Sons Ltd.

ATOPIC DERMATITIS: NEW ASPECTS OF TREATMENT

Directory of Open Access Journals (Sweden)

D. Sh. Macharadze

2013-01-01

Full Text Available Atopic dermatitis is a chronic inflammatory cutaneous disease, which demands a prolonged treatment. A modern views on the main approaches to treatment of atopic dermatitis in children and adults are analyzed in this article. The treatment is based on the permanent use of emollients in order to achieve an anti-inflammatory effect — topical calcineurin inhibitors (tacrolimus and pimecrolimus, and short courses (5 days of topical corticosteroids during relapses. For the 10-year period of topical calcineurin inhibitors usage in treatment of atopic dermatitis a great amount of experimental and clinical data have been accumulated. Two the most important changes and additions in the treatment of atopic dermatitis in recent times were related to a new hypothesis of proactive therapy with the use of topical tacrolimus and closing of «black box» warnings, associated to malignization risk due to the long-term usage of topical calcineurin inhibitors. Since atopic dermatitis is characterized by relapsing course, nowadays topical tacrolimus should be considered the most appropriate treatment approach, both in adults and children. The results of investigations confirmed more than 6-times decrease in relapse rate, as well as the significant improvement of quality of life, when the above-mentioned treatment scheme is used, both in children and adults.Key words: children, atopic dermatitis, emollients, treatment, tacrolimus.

Atopic dermatitis results in intrinsic barrier and immune abnormalities: Implications for contact dermatitis

Science.gov (United States)

Gittler, Julia K.; Krueger, James G.; Guttman-Yassky, Emma

2014-01-01

Atopic dermatitis (AD), as well as irritant contact dermatitis (ICD) and allergic contact dermatitis (ACD), are common skin diseases. These diseases are characterized by skin inflammation mediated by activated innate immunity or acquired immune mechanisms. Although AD, ICD, and ACD can be encountered in pure forms by allergists and dermatologists, patients with AD often present with increased frequency of ICD and ACD. Although a disturbed barrier alone could potentiate immune reactivity in patients with AD through increased antigen penetration, additional immune mechanisms might explain the increased susceptibility of atopic patients to ICD and ACD. This review discusses cellular pathways associated with increased skin inflammation in all 3 conditions and presents mechanisms that might contribute to the increased rate of ICD and ACD in patients with AD.

Sood, N K; Mekkib, Berhanu; Singla, L D; Gupta, K

2012-04-01

Out of 44 cases of dermatitis in dogs, 11 cases of parasitic origin were analyzed by cytopathology. Histopathologic examination of punch biopsies was also done for correlation with cytologic findings. Sarcoptic dermatitis was recorded in six cases, wherein, besides sarcoptic mites, neutrophils, macrophages, and plasma cells and keratinizing epithelial cells were also seen. Hematology revealed a relative neutrophilia and mild eosinophilia. Four cases of severe and generalized demodicosis complicated with bacteria and/or Malassezia sp. infection were also recorded. Histopathologically numerous Demodex sp. mites in varying stage of maturation were found damaging the hair follicles along with associated pathological changes and foreign body granulomas in one case. In addition, flea allergy dermatitis was also observed in one dog. In nutshell, cytology was found to be unequivocally effective in diagnosing parasitic dermatitis.

Allergic contact dermatitis to fragrances: part 2.

Science.gov (United States)

Arribas, M P; Soro, P; Silvestre, J F

2013-01-01

Allergic contact dermatitis due to fragrances usually manifests as subacute or chronic dermatitis because fragrances are found in a wide range of products to which patients are repeatedly exposed. The typical patient is a middle-aged woman with dermatitis on her hands and face, although other sites may be affected depending on the allergen and the product in which it is found. The standard patch test series of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) contains 4 fragrance markers: balsam of Peru, fragrance mix i, fragrance mix ii, and lyral. Testing with a specific fragrance series is recommended in patients with a positive result to any of these 4 markers. The use of a specific fragrance series and new legislation obliging manufacturers to specify the fragrances used in their products, will help to improve the management of allergic contact dermatitis due to fragrances.

Pediatric contact dermatitis

Directory of Open Access Journals (Sweden)

Sharma Vinod

2010-01-01

Full Text Available Allergic contact dermatitis (ACD in children, until recently, was considered rare. ACD was considered as a disorder of the adult population and children were thought to be spared due to a lack of exposure to potential allergens and an immature immune system. Prevalence of ACD to even the most common allergens in children, like poison ivy and parthenium, is relatively rare as compared to adults. However, there is now growing evidence of contact sensitization of the pediatric population, and it begins right from early childhood, including 1-week-old neonates. Vaccinations, piercing, topical medicaments and cosmetics in younger patients are potential exposures for sensitization. Nickel is the most common sensitizer in almost all studies pertaining to pediatric contact dermatitis. Other common allergens reported are cobalt, fragrance mix, rubber, lanolin, thiomersol, neomycin, gold, mercapto mix, balsum of Peru and colophony. Different factors like age, sex, atopy, social and cultural practices, habit of parents and caregivers and geographic changes affect the patterns of ACD and their variable clinical presentation. Patch testing should be considered not only in children with lesions of a morphology suggestive of ACD, but in any child with dermatitis that is difficult to control.

Cheyletiella Blakei Dermatitis

Full Text Available Cheyletiellosis (cheyletiella dermatitis is a dermatitis caused by cheyletiella mites that are seen more commonly in cats, dogs and rabbits all over the world. Cheyletiella blakei, which is naturally hosted by cats, causes infestations in people, especially who are in close contact with infested cats. The diagnosis of cheyletiellosis in humans is established by the suspicion of physician or veterinarian and demonstration of the mites in cats. If not suspected, cheyletiellosis may be thought as delusions of parasitosis and may be undiagnosed. A 48-year-old woman presented to our clinic with red, pruritic papules on the chest, abdomen, arms and anterior thighs. There was no remission of the complaints of the patient after 3 days of topical corticosteroid treatment. Following more detailed examination and medical history, cheyletiellosis was suspected. The diagnosis was confirmed by a veterinary control of the cat that the women had started feeding at home about 15 days ago. Although cheyletiella dermatitis is not uncommon, most cases are undiagnosed because it is not a well-known dermatosis by dermatologists. As far as we know, there is no previously reported cheyletiella case in our country. (Turk­derm 2011; 45: 213-5

Brown, T P; Rushton, L; Williams, H C; English, J S C

2006-04-01

Intervention development research is an essential prerequisite of any study that attempts to determine whether specific interventions work to prevent work related injury and illness. Focus groups (n = 5) and direct observational studies (n = 21) of printers were used to elicit key issues that would aid the development of subsequent interventions. Transcripts from these were analysed by standard qualitative methods to identify common and related themes. The views of managers differed significantly from those of print workers in a number of areas, and working practices did not always follow policy. The majority of printers did not perceive dermatitis to be a major problem, although many complained of dry hands. Other key results included: the lack of skin care policy in most companies; poor understanding of the nature, causes, and treatment of dermatitis; low priority of dermatitis within health and safety concerns; little or no provision of occupational health services, particularly skin checks; variability in provision of and access to appropriate skin protection; and lack of accessible washing facilities. As a result it was decided to evaluate the implementation of four provision of (1) skin checks and treatment advice; (2) gloves of the correct type and size, and use of an after-work cream; (3) information on dermatitis within the printing industry; and (4) development of best practice skin care policy.

BACKGROUND: Common filaggrin (FLG) null mutations are associated with severe and early onset of atopic dermatitis (AD). To date, few studies have investigated anatomical patterns of dermatitis and none has been conducted in the general population. OBJECTIVE: We evaluated patterns of dermatitis...... by use of questionnaires. Participants were genotyped for common FLG mutations. A history of AD was defined by the United Kingdom Working Party's diagnostic criteria. RESULTS: The frequency of foot dermatitis in the general population was associated with FLG genotype (P = .014). However, when...... stratification of FLG genotype and AD was performed, we found that FLG mutations increased the prevalence (odds ratios) of foot dermatitis (odds ratio 10.41; 95% confidence interval 5.27-20.60) and persistent hand dermatitis (odds ratio 17.57; 95% confidence interval 8.60-35.89) only in participants with AD...

Radiation dermatitis occurs in 95% of the women undergoing radiation therapy (RT) for breast cancer. Radiation dermatitis is one of the common acute side effects of RT and includes erythema, dry desquamation, and moist desquamation. Radiation dermatitis may cause physical distress, such as pain and itchiness, and influence individual's quality of life as well. Nurses are to reduce the distress and improve quality of life by managing the symptoms and enhancing patient's self-care ability. This article describes the supportive care for radiation dermatitis from nurse's point of view. (author)

Granulomatous dermatitis due to Malassezia sympodialis.

Desai, Harsha B; Perkins, Philip L; Procop, Gary W

2011-09-01

A 67-year-old man, with multiple skin lesions that appeared over 2 years, had biopsies that disclosed granulomatous dermatitis with associated small yeasts. The urinary antigen test results were negative for Histoplasma infection; cultures from the biopsies did not grow any fungi or other potential pathogens. The chest roentgenogram results were normal. Morphologic examination revealed features of a Malassezia species. Broad-range fungal polymerase chain reaction and DNA sequencing disclosed that the infecting fungus was Malassezia sympodialis , a lipid-dependent yeast. This report supports one other case report that Malassezia species may cause granulomatous dermatitis; in the previous case, the etiologic agent was Malassezia pachydermatis , a nonlipid-dependent species. We recommend the use of lipid-supplemented culture media for specimens from patients with granulomatous dermatitis because several Malassezia species are dependent on lipid; the absence of lipid supplementation in routine cultures likely explains the negative culture results for this patient. This, to our knowledge, is the first report of granulomatous dermatitis caused by M sympodialis.

Experimental photoallergic contact dermatitis: a mouse model

Maguire, H.C. Jr.; Kaidbey, K.

1982-01-01

We have induced photoallergic contact dermatitis in mice to 3,3',4',5 tetrachlorosalicylanilide (TCSA), chlorpromazine and 6-methylcoumarin. These compounds are known to produce photoallergic contact dermatitis in humans. The photoallergic contact dermatitis reaction in the mouse is immunologically specific viz. mice photosensitized to TCSA react, by photochallenge, to that compound and not to chlorpromazine, and conversely. The reaction requires UVA at both sensitization and challenge. It appears to be T-cell mediated in that it can be passively transferred to syngeneic mice by lymph node cells from actively sensitized mice, the histology of the reactions resembles that of classic allergic contact dermatitis in mice, challenge reactions are seen at 24 but not at 4 hr, and photoallergic contact dermatitis can be induced in B-cell deficient mice. The availability of a mouse model for the study of photo-ACD will facilitate the identification of pertinent control mechanisms and may aid in the management of the disease. It is likely that a bioassay for photoallergens of humans can be based on this mouse model

Full Text Available BACKGROUND: Due to recent industrialization and inadequately protected workers or in other words poor supervision on constructive workers habits in our large city of Isfahan cement contact dermatitis is relatively high especially among cement factory workers and constructive personnel. PURPOSES: To investigate the prevalence rate of cement contact dermatitis in cement factory workers in Isfahan. METHODS: A case-control clinical study was carried out by randomly selecing 150 factory workders and 150 official clerks in a cement factory in Isfahan in 2001. After a complete physical examination, data was recorded in observational checklists. FINDINGS: The percentages of contact dermatitis prevalences in the first and the second groups were 22% and 5.3% respectively. About 60% of cement workers with contact dermatitis were between 30-40 years of age. There was a direct relationship with age in both groups of the workers. In the high-exposure group, the hand eczema along was 70% but in the other group the percentage of involvement was the same in exposed and unexposed anatomical areas. CONCLUSIONS: There was a direct relationship between occurrence and the severity of involvement and duration of contact in the first group. Cent percent of cement workers had contact dermatitis after 10 or less years, but the percentage among the other group was 35%. LIMITATION: Irritant contact dermatitis to cement has not been detected.

The American Contact Dermatitis Society (ACDS) is the principal organization representing the subspecialty of contact dermatitis in the United States. The aim of this study was to characterize ACDS members with respect to demographic characteristics, patch-test practices, and sentiments regarding the Society and its journal Dermatitis. We conducted cross-sectional postal and online surveys of ACDS members. More than a third of ACDS members responded to the survey, 92% of whom practice dermatology, and most of whom are community practitioners. Responders manage patients with allergic and irritant dermatitis at a similar frequency. On average, they patch test 4 patients per week using 66 allergens per patient, which often include customized trays. Almost half of these practitioners learned patch testing from their residency programs. Most of the responders read and value the Society journal, value the Contact Allergen Management Program database, and attend society meetings. The ACDS is comprised overwhelmingly of dermatologists who are primarily community-based, young relative to the start of their practices, and use the Society's resources for continuing education.

Allergies are often suspected in cats and they are mainly hypersensitivity reactions against insect bites, food- or environmental allergens. Cats, with non flea induced atopic dermatitis, normally present with one oft he following reaction patterns: miliary dermatitis, eosinophilic dermatitis, selfinduced alopecia or head and neck excoriations. None of these reaction patterns is nevertheless pathognomonic for allergic dermatitis, therefore the diagnosis is based on the one hand on the exclusion of similar diseases on the other hand on the successful response on a certain therapy. Recently a study on the clinical presentation of cats with non flea induced atopic dermatitis was published. In this study certain criteria for diagnosing atopy in cats were proposed. For therapy of allergic cats cyclosporin, glucocorticoids, antihistamines, hypoallergenic diets and allergen specific immunotherapy are used. This article should provide a recent overview on the clinical symptoms, diagnosis and therapy of feline allergic dermatitis.

Full Text Available Chronic actinic dermatitis (CAD is characterized by persistent eczema-like lesions, mainly on sun-exposed sites, induced by ultraviolet B, sometimes ultraviolet A, and occasionally visible light. CAD is a rare photodermatitis. It is often associated with contact allergens including airborne allergens such as fragrances, plant antigens and topical medications. A 62 year old farmer is applied with eczematous lesions restricted to sun-exposed areas. Clinical findings and histopathologic features were consistent with the diagnosis of chronic actinic dermatitis. The patient also had contact allergy to multiple allergens. We present this case to emphasize the significance of patch test on CAD treatment and the success of topical tacrolimus and azathioprine.

Gosnell, Amy L; Schmotzer, Brian; Nedorost, Susan T

2015-01-01

Patients with allergic contact dermatitis to 1 antigen have been shown to be at increased risk of developing delayed type hypersensitivity reactions to additional antigens. Both environmental and genetic factors likely influence the risk of sensitization. The aim of this study was to determine whether polysensitization occurs at a higher frequency than would be expected based on chance and whether polysensitization occurs more often in subsets of patients with hand involvement and atopic dermatitis. From a database of patch test results from a single practitioner, the probability of having positive reactions to 3 or more unrelated allergens was calculated under the assumption that positive reactions are independent and compared with the observed proportion having positive reactions to 3 or more unrelated allergens. The analysis was repeated excluding patients with leg involvement as a proxy for venous insufficiency dermatitis. The proportion of patients from the polysensitized and nonpolysensitized cohorts with either hand involvement or a history of atopic dermatitis was also calculated. Polysensitization occurs more often than expected based on chance. Polysensitized patients were more likely to have hand dermatitis. Atopic dermatitis was not significantly associated with polysensitization in this analysis. Polysensitized individuals may represent a phenotype with increased genetic susceptibility to sensitization.

The diagnosis of skin diseases relies on several clinical signs, among which color is of paramount importance. In this review, we consider certain clinical presentations of both eczematous and noneczematous contact dermatitis in which color plays a peculiar role orientating toward the right diagnosis. The conditions that will be discussed include specific clinical-morphologic subtypes of eczematous contact dermatitis, primary melanocytic, and nonmelanocytic contact hyperchromia, black dermographism, contact chemical leukoderma, and others. Based on the physical, chemical, and biologic factors underlying a healthy skin color, the various skin shades drawing a disease picture are thoroughly debated, stressing their etiopathogenic origins and histopathologic aspects.

A Case of Apparent Contact Dermatitis Caused by Toxocara Infection

Directory of Open Access Journals (Sweden)

Rosanna Qualizza

2014-01-01

Full Text Available Infection from Toxocara species may give rise to a large array of clinical symptoms, including apparent manifestations of allergy such as asthma, urticaria/angioedema, and dermatitis. We report a case, thus far not described, of contact dermatitis attributed to nickel allergy but caused by Toxocara infection. The patient was a 53-year-old woman presenting from 10 years a dermatitis affecting head, neck, and thorax. Patch tests initially performed gave a positive result to nickel, but avoidance of contact with nickel did not result in recovery. The patient referred to our Allergy Service in 2010 because of dermatitis to feet. Patch testing confirmed the positive result for nickel, but expanding the investigation a positive result for IgG antibodies to Toxocara was detected by Western blotting and ELISA. Treatment with mebendazole achieved immediate efficacy on feet dermatitis. Then, two courses of treatment with albendazole resulted in complete regression of dermatitis accompanied by development of negative ELISA and Western blotting for Toxocara antibodies. This report adds another misleading presentation of Toxocara infection as apparent contact dermatitis caused by nickel and suggests bearing in mind, in cases of contact dermatitis not responding to avoidance of the responsible hapten and to medical treatment, the possible causative role of Toxocara.

Methylisothiazolinone testing at 2000 ppm: a prevalent sensitizer for allergic contact dermatitis.

Science.gov (United States)

Ham, Kaiya; Posso-De Los Rios, Claudia J; Gooderham, Melinda

2015-01-01

Methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) have been identified as potent allergens. The optimal MI concentration for patch testing for reaction to these agents has not yet been identified, but it has been suggested that testing MI at 2000 ppm may reduce false-negative reactions. The aim of this study was to report allergic reactions to MI and MCI/MI detected in a community dermatology practice setting in Ontario, Canada. The patch test records of patients with suspected allergic contact dermatitis seen between October 2007 and June 2014 were reviewed. We compared positive patch testing before and after December 2011 when a higher MI concentration was used (2000 ppm aqueous) in addition to the baseline series MCI/MI at 100 ppm. A total of 794 patient records were reviewed. There were 38 true-positive reactions to MI or MCI/MI. Of these 38 patients, 26 (68%) were female. We detected an overall increase in the rate of positive patch testing to MCI/MI, MI alone, or both from 3.13% to 7.45% when MI concentration was introduced at 2000 ppm aqueous. Occupational differences existed between sexes. The addition of MI at 2000 ppm to our screening series effectively increased the detection of MI-induced allergic contact dermatitis.

The most common differential diagnoses for patients presenting with lip dermatitis or inflammation include atopic, allergic, and irritant contact dermatitis. Patch testing can be performed to identify the allergic contact conditions. To report North American Contact Dermatitis Group (NACDG) patch-test results of patients who presented for patch testing with only lip involvement from 2001 to 2004. Patient characteristics, allergen frequencies, relevance, final diagnoses, and relevant allergic sources not in the NACDG screening series were evaluated. The NACDG 2001-2004 database was used to select patients presenting with only lip involvement. Of 10,061 patients tested, 2% (n = 196) had lips as the sole involved site. Most (84.2%) were women. After patch testing, 38.3% (n = 75) were diagnosed with allergic contact cheilitis. Fragrance mix, Myroxilon pereirae, and nickel were the most common relevant allergens. Of 75 patients, 27 (36%) had relevant positive patch-test reactions to items not on the NACDG series; lipstick and cosmetics were the predominant sources. Patch testing is valuable in the evaluation and identification of contact allergy in patients referred for lip dermatitis. The use of supplementary allergens based on history and exposure is important in the identification of additional relevant allergens. Over a third of patients with contact allergy had other factors, such as irritant dermatitis, considered relevant to their condition.

Diagnosing Allergic Contact Dermatitis Through Elimination, Perception, Detection and Deduction.

Pongpairoj, Korbkarn; Puangpet, Pailin; Thaiwat, Supitchaya; McFadden, John P

2017-10-01

Several authors have commented upon the skills of detection required in making a diagnosis of allergic contact dermatitis. Here, we emphasise the search for clues in a systematic manner. We describe four stages as part of a systematic method for diagnosing allergic contact dermatitis. Firstly, elimination (or inclusion) of non-allergic diagnoses. Secondly, perception: the pre-patch test diagnosis and the 'three scenarios' principle. Thirdly, detection: optimising the sensitivity of the patch test process. Fourthly, deduction: diagnosing allergic contact dermatitis by associating the dermatitis with the allergen exposure. We further compare and contrast the pre-patch test history and examination with the markedly different one ('microhistory' and 'microexamination') used after patch testing. The importance of knowledge of contact dermatitis literature is emphasised with a review of recent publications. Finally, we also highlight the use of contact allergy profiling as an investigative tool in the diagnosis of allergic contact dermatitis.

Metal Allergy and Systemic Contact Dermatitis: An Overview

Directory of Open Access Journals (Sweden)

Yoko Yoshihisa

2012-01-01

Full Text Available Contact dermatitis is produced by external skin exposure to an allergen, but sometimes a systemically administered allergen may reach the skin and remain concentrated there with the aid of the circulatory system, leading to the production of systemic contact dermatitis (SCD. Metals such as nickel, cobalt, chromium, and zinc are ubiquitous in our environment. Metal allergy may result in allergic contact dermatitis and also SCD. Systemic reactions, such as hand dermatitis or generalized eczematous reactions, can occur due to dietary nickel or cobalt ingestion. Zinc-containing dental fillings can induce oral lichen planus, palmoplantar pustulosis, and maculopapular rash. A diagnosis of sensitivity to metal is established by epicutaneous patch testing and oral metal challenge with metals such as nickel, cobalt, chromium, and zinc. In vitro tests, such as the lymphocyte stimulating test (LST, have some advantages over patch testing to diagnose allergic contact dermatitis. Additionally, the determination of the production of several cytokines by primary peripheral blood mononuclear cell cultures is a potentially promising in vitro method for the discrimination of metal allergies, including SCD, as compared with the LST.

Full Text Available This paper shows a case of eczema herpeticatum associated with dermatitis atopica in a two-year-old boy. Eczema herpeticatum was developed as a complication due to irregular topical treatment of atopic dermatitis for a longer period of time (up to 5 months. The boy was initially treated with a few types of topical steroids, and then with topical immune suppressant (pimecrolimus 1% cream. The diagnosis has been confirmed by family history of allergic disorders, clinical and laboratory findings.

Abhijit Saha

2015-01-01

Full Text Available Dermatitis neglecta is a condition that results from inadequate frictional cleansing leading to accumulation of corneocytes, sebum and sweat ultimately resulting in hyper-pigmented patch or verrucous plaque. Recognizing this condition avoids unnecessary, aggressive diagnostic and therapeutic procedures. Here we report three cases of dermatitis neglecta in whom the dermatitis developed as a result of intentional neglect of personal hygiene.

Landis, Megan N; Keeling, James H; Yiannias, James A; Richardson, Donna M; Nordberg Linehan, Diane L; Davis, Mark D P

2012-09-01

Peristomal dermatitis is a common problem in patients with ostomies that is a source of considerable morbidity. Irritant contact dermatitis is most common, but allergic contact dermatitis can also occur. Because of the lack of published reports on patch testing for this indication, we undertook a retrospective study of patch testing results in patients with suspected peristomal allergic contact dermatitis. We sought to describe our patch testing experience with patients referred with peristomal dermatitis. This was a retrospective review of medical records of patients with ostomies and peristomal dermatitis who underwent patch testing in the Mayo Clinic Departments of Dermatology in Jacksonville, FL; Rochester, MN; and Scottsdale, AZ, during a 10-year period (2000-2010). Ten patients with peristomal dermatitis were referred for patch testing (6 in Minnesota, 2 in Florida, and 2 in Arizona). Patients were patch tested to the materials used in their stoma devices, to the standard series, and in some cases to supplemental series. All 10 had at least one allergic patch test reaction, most commonly to stoma paste (3 of 10 patients). Retrospective nature of study via chart review is a limitation. Patch testing is a useful tool for identification of allergens in patients with peristomal dermatitis. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc.

Can atopic dermatitis be prevented?

Science.gov (United States)

Gómez-de la Fuente, E

2015-05-01

Atopic dermatitis has become a health problem in our setting due to its rising prevalence, impact on quality of life, associated costs, and role in the progression to other atopic diseases. Furthermore, atopic dermatitis has no definitive cure and therefore preventive measures are important. In this article, we review the latest advances in both primary prevention (reduction of the incidence of atopic dermatitis) and secondary prevention (reduction of associated morbidity and reduction of the atopic march). We analyze the different preventive strategies available, including modification of the immune system through microbial exposure, induction of immune tolerance through antigen exposure, and restoration of skin barrier function to halt the atopic march. Dermatologists need to be familiar with these strategies in order to apply them where necessary and to accurately inform patients and their relatives to prevent misguided or inappropriate actions.

Interstitial Granulomatous Dermatitis (IGD

Tiberiu Tebeica

2017-07-01

Full Text Available We report the case of a 42 years old male patient suffering from skin changes , which appeared in the last 7-8 years.  Two biopsies were performed during the evolution of the lesion. Both showed similar findings that consisted in a busy dermis with interstitial, superficial and deep infiltrates of lymphocytes and histiocytes dispersed among collagen bundles, with variable numbers of neutrophils scattered throughout. Some histiocytes were clustered in poorly formed granuloma that included rare giant cells, with discrete Palisades and piecemeal collagen degeneration, but without mucin deposition or frank necrobiosis of collagen. The clinical and histologic findings were supportive for interstitial granulomatous dermatitis. Interstitial granulomatous dermatitis (IGD is a poorly understood entity that was regarded by many as belonging to the same spectrum of disease or even synonym with palisaded and neutrophilic granulomatous dermatitis (PNGD. Although IGD and PNGD were usually related to connective tissue disease, mostly rheumatoid arthritis, some patients with typical histologic findings of IGD never develop autoimmune disorders, but they have different underlying conditions, such as metabolic diseases, lymphoproliferative disorders or other malignant tumours. These observations indicate that IGD and PNGD are different disorders with similar manifestations.

Full Text Available Christina M Gelbard1, Adelaide A Hebert1,21Departments of Dermatology; 2Pediatrics, University of Texas-Houston, Houston, TX, USAAbstract: Atopic dermatitis is a chronic, inflammatory skin condition that affects 10% to 20% of children and 1% to 3% of adults in the US. Symptoms often result in sleeplessness, psychological stress, poor self-esteem, anxiety, and poor school or work performance. The cost of atopic dermatitis is estimated to be US$0.9 to 3.8 billion every year. Topical steroids are first-line treatment for atopic dermatitis, and recent advances in vehicle technologies have resulted in improved patient tolerability and compliance. Topical calcineurin inhibitors are also safe and effective topical treatments for atopic dermatitis, and provide an additional therapeutic option for patients with this disease. Systemic immunomodulators are used in the treatment of severe refractory disease. Cyclosporine, methotrexate, azathioprine, mycophenolate mofetil, and interferon gamma have been used in the management of severe atopic dermatitis. This review highlights the current and emerging trends in the treatment of atopic dermatitis.Keywords: atopic dermatitis, topical corticosteroids, calcineurin inhibitors, methotrexate, cyclosporine, mycophenolate mofetil, IFN-γ

Science.gov (United States)

Holcomb, Zachary E; Van Noord, Megan G; Atwater, Amber Reck

Allergic contact dermatitis related to cosmetic use can result from allergens not routinely evaluated by standard patch test protocols. Propyl, octyl, and dodecyl gallates are commonly used antioxidant preservatives with reports of associated allergic contact dermatitis in the literature. The objectives of this review were to investigate the role of gallates in allergic contact dermatitis and to explore products containing these preservatives. A systematic review of the literature through April 2016 was performed to explore cases of reported gallate allergy. Food and cosmetic product databases were searched for products containing gallates. Seventy-four cases of gallate contact allergy have been reported. In addition, a variety of commercially available cosmetic products and foods contain gallate chemicals. Propyl gallate is the most commonly reported gallate contact allergen and often causes facial and/or hand dermatitis.

Dermatitis in small-scale metal industries

Coenraads, P J; Foo, S C; Phoon, W O; Lun, K C

1985-03-01

A survey in 21 small metal factories in Singapore revealed that 6.6% of 751 workers (530 male, 221 female) had a skin disorder on their hands and arms. Dermatitis accounted for 4.5% (34 cases) and follicular rashes for 1% (8 cases). Positive patch tests were found in 23% (8 cases) of those with dermatitis and in 9.8% (21 workers) of a control group without any skin problem. Dermatitis was found to be associated with exposure to solvents. Simultaneous analysis of various exposure/risk factors by multiple logistic regression indicated a significant effect of combined exposure to oils and solvents (interaction). Being over 35 years of age was also a significant risk factor, whereas the role of contact allergy, detected by patch testing, was less pronounced.

Atopic and Contact Dermatitis of the Vulva.

2017-09-01

Pruritus, or itch, is a common vulvar complaint that is often treated empirically as a yeast infection; however, yeast infections are just one of the many conditions that can cause vulvar itch. Ignoring other conditions can prolong pruritus unnecessarily. Atopic dermatitis, irritant contact dermatitis, and allergic contact dermatitis are extremely common noninfectious causes of vulvar itch that are often underdiagnosed by nondermatologists. Identifying these conditions and treating them appropriately can significantly improve a patient's quality of life and appropriately decrease health care expenditures by preventing unnecessary additional referrals or follow-up visits and decreasing pharmaceutical costs.

Full Text Available Background and Design: Allergic contact dermatitis is a delayed type hypersensitivity reaction to allergens in individuals who were sensitized with same allergens before. The causative allergens may change in time as well as vary among geographical and population based differences. Materials and Methods: The characteristics of 169 patients-107 (63.3% male, 62 (36.7% female, who patch tested between 2011- 2014 with allergic contact dermatitis diagnosis and test results were retrospectively analysed. Results: The mean age of all patients who had the most frequent occupation as service sector/house wife (26.6% were 41.06 years and the mean disease duration of all patients was 19.5 months. The most frequent localization of disease was hands (n: 105,%73 and %50.3 of patients had positivity with at least one allergen. The most frequent seven allergens with positivity were nickel sulfate (n: 50, %29.6, cobalt chloride (n: 23, %13.6, potassium dichromate (n: 22, %13, sesquiterpene lactone mix (n: 18, %10.7, thiuram (n: 10, %5.9, clioquinol mix (n: 10, %5.9 and 4-tert-butilfenol formaldehyde resin (n: 10, %5.9, respectively. On the other hand in all patients there were no positivity with N-Isopropyl-N-phenyl-4-phenylenediamine, epoxy resin, balsam of peru, formaldehyde, quaternium-15, primin, tixocortol-21-pivalate, fragrance mix-2. Conclusion: In comparison of this study which first reports patch test results of patients in Tekirdağ-a city in Trakya region and other studies that report patch test results of different regions of our country; the mean age of patients of present study were older and there were similar results for occupations and localization of disease in between eastern region and present study. We believe that further studies are needed to specify allergen characteristics of Trakya region using multicenter studies, which include other cities as well.

Successful management of atopic dermatitis poses a significant and ongoing challenge to parents of affected children. Despite frequent reports of child behaviour problems and parenting difficulties, there is a paucity of literature examining relationships between child behaviour and parents' confidence and competence with treatment. To examine relationships between child, parent, and family variables, parents' self-efficacy for managing atopic dermatitis, self-reported performance of management tasks, observed competence with providing treatment, and atopic dermatitis severity. Cross-sectional study design. Participants A sample of 64 parent-child dyads was recruited from the dermatology clinic of a paediatric tertiary referral hospital in Brisbane, Australia. Parents completed self-report questionnaires examining child behaviour, parents' adjustment, parenting conflict, parents' relationship satisfaction, and parents' self-efficacy and self-reported performance of key management tasks. Severity of atopic dermatitis was assessed using the Scoring Atopic Dermatitis index. A routine home treatment session was observed, and parents' competence in carrying out the child's treatment assessed. Pearson's and Spearman's correlations identified significant relationships (pconflict, and relationship satisfaction. There were also significant relationships between each of these variables and parents' self-reported performance of management tasks. More profound child behaviour difficulties were associated with more severe atopic dermatitis and greater parent stress. Using multiple linear regressions, significant proportions of variation in parents' self-efficacy and self-reported task performance were explained by child behaviour difficulties and parents' formal education. Self-efficacy emerged as a likely mediator for relationships between both child behaviour and parents' education, and self-reported task performance. Direct observation of treatment sessions revealed strong

Occupational allergy as a challenge to developing countries.

A steady increase in the incidence of allergic diseases can be observed since 1950s. For such atopic diseases as bronchial asthma, pollinosis or atopic dermatitis, a significantly increased morbidity rate in the general population has been found. Strikingly enough, the highest prevalence of asthma and allergy was recorded in highly developed countries. It can thus be assumed that the high rate of asthma may be an attribute of the post-industrial societies. The prevalence of occupational allergies is thought to be in direct proportion to the rate with which allergies occur in the general population. In view of the changing environment and lifestyles in the developing countries, their communities are expected to be faced with similar negative epidemiological effects concerning allergies. To counteract the spreading of negative health effects, the following measures need to be undertaken: 1. Limitation of exposure to strong allergens. 2. Modification of the training curriculum for medical personnel and of health service infrastructure, according to new tasks and challenges. 3. Considering a possibility of introducing a system of surveillance over occupational allergies and asthma, like the Surveillance of Work-related and Occupational Respiratory Disease (SWORD) system implemented in UK. This system ensures effective cooperation between specialists in preventive medicine, occupational hygiene services and research workers dealing with occupational health that enables prompt response to emerging hazards.

Abstract Dermatologic diseases are not traditional risk factors of stroke, but recent studies show atopic dermatitis, psoriasis, and bullous skin disease may increase the risk of stroke and other cardiovascular diseases. No previous studies have focused on the association between contact dermatitis and stroke. We established a cohort comprised of 48,169 contact dermatitis patients newly diagnosed in 2000–2003 and 96,338 randomly selected subjects without the disorder, frequency matched by sex, age, and diagnosis year, as the comparison cohort. None of them had a history of stroke. Stroke incidence was assessed by the end of 2011 for both cohorts. The incidence stroke was 1.1-fold higher in the contact dermatitis cohort than in the comparison cohort (5.93 vs 5.37 per 1000 person-years, P contact dermatitis cohort increased with age, from 1.14 (95% CI, 1.03–1.27) for 65 to 74 years; to 1.27 (95% CI, 1.15–1.42) for 75 years and older. The aHR of stroke were 1.16 (95% CI, 1.07–1.27) and 1.09 (95% CI, 1.00–1.18) for men and women, respectively. This study suggests that patients with contact dermatitis were at a modestly increased risk of stroke, significant for ischemic stroke but not for hemorrhagic stroke. Comorbidity, particularly hypertension, increased the hazard of stroke further. PMID:28272195

Contact dermatitis to personal sporting equipment in youth is poorly studied. To review the results of patch testing 6 youth to their sporting equipment in a dermatology general private practice from 2006 to 2011. A retrospective analysis of 6 youth aged 11 to 14 who were evaluated for chronic and persistent dermatitis occurring in relation to sports equipment was conducted. All patients were subjected to epicutaneous (patch) testing, which included some or all of the following: North American Contact Dermatitis Group (NACGD) series, textile series, rubber series, corticosteroid series, and raw material from the patients' own personal equipment. All cases had 1 or more positive patch test reactions to an allergen within the aforementioned series, and 3 subjects tested positive to their personal equipment in raw form. Allergic contact dermatitis, not irritant, was deemed the relevant cause of chronic dermatitis in 4 of the 6 patients due to positive reactions to epicutaneous tests and/or personal equipment. The utility of testing to patients' own sporting equipment was shown to be of additional value and should be considered when patch testing for contact allergy to sporting equipment. © The Author(s) 2015.

Systemic contact dermatitis can be elicited experimentally in nickel-sensitive individuals by oral nickel exposure. A crucial point interpreting such experiments has been the relevance of nickel exposure from drinking water and diet. The aim of this meta-analysis study on former nickel......-exposure investigations was to provide the best possible estimation of threshold values of nickel doses that may cause systemic contact dermatitis in nickel-sensitive patients. 17 relevant investigations were identified, and statistical analyses were performed in a stepwise procedure. 9 studies were included in the final...... of the doses that, theoretically, would cause systemic contact dermatitis in exposed nickel-sensitive patients. The results from the 2 most sensitive groups show that 1% of these individuals may react with systemic contact dermatitis at normal daily nickel exposure from drinking water and diet, i.e. 0...

2013-01-01

Full Text Available The article analyzes modern data on risk factors of severe course of atopic dermatitis in children: the role of alimentary and inhalant allergens, cutaneous infections, allergic reactions to drugs used in the treatment of disease. The most important questions of differential diagnosis of atopic dermatitis in children and the distinctive features of the illness, which may be mistaken for atopic dermatitis (primary immunodeficiencies, keratosis pilaris, psoriasis, enteropatic acrodermatitis; cutaneous bacterial and fungal infections, and drug-induced contact dermatitis to topical creams and ointments are discussed. Treatment of atopic dermatitis is based on modern approaches and includes recommendations on the use of emolents, anti-inflammatory drugs (topical glucocorticoids and calcineurin inhibitors. The article provides indications and contraindications to the administration of anti-inflammatory drugs. Special recommendations for use of cleansers and emolents at all degrees of severity of atopic dermatitis, which helps reduce the risk of side effects of topical corticosteroids, complications such as cutaneous infections and helps to maintain remission of disease are given. The importance of training programs patients is emphasized. Compliance of patients and/or their parents contributes to the achievement of the desired effect of the treatment of atopic dermatitis, which will improve the patients’ quality of life.

Management of Patients with Atopic Dermatitis: The Role of Emollient Therapy

Directory of Open Access Journals (Sweden)

M. Catherine Mack Correa

2012-01-01

Full Text Available Atopic dermatitis is a common inflammatory skin disorder that afflicts a growing number of young children. Genetic, immune, and environmental factors interact in a complex fashion to contribute to disease expression. The compromised stratum corneum found in atopic dermatitis leads to skin barrier dysfunction, which results in aggravation of symptoms by aeroallergens, microbes, and other insults. Infants—whose immune system and epidermal barrier are still developing—display a higher frequency of atopic dermatitis. Management of patients with atopic dermatitis includes maintaining optimal skin care, avoiding allergic triggers, and routinely using emollients to maintain a hydrated stratum corneum and to improve barrier function. Flares of atopic dermatitis are often managed with courses of topical corticosteroids or calcineurin inhibitors. This paper discusses the role of emollients in the management of atopic dermatitis, with particular emphasis on infants and young children.

Quaternary ammonium compounds – New occupational hazards

Directory of Open Access Journals (Sweden)

Agnieszka Lipińska-Ojrzanowska

2014-10-01

Full Text Available Quaternary ammonium compounds (QACs, quats belong to organic ionic chemical agents which display unique properties of both surfactants and disinfectants. Their wide distribution in the work environment and also in private households brings about new occupational hazards. This paper reviews reports about the health effects of QACs. QACs could play a role of sensitizers and irritants to the skin and mucous membranes. It is suspected that particular QACs can display an immunologic crossreactivity between each other and with other chemical compounds containing ammonium ion, such as muscle relaxants widely used in anesthesia. They may promote the development of airway allergy, however, the background mechanisms are still unclear and need to be further investigated. Until now, a few cases of occupational asthma induced by QACs have been described and their involvement in contact dermatitis has been documented. The possibility of anaphylaxis due to QACs cannot be excluded as well. Med Pr 2014;65(5:675–682

Objective: To evaluate the effect of recombinant human epidermal growth factor (Gene Time) on acute mucositis and dermatitis induced by radiation. Methods: 120 head and neck cancer patients were randomized into 3 groups: 1. Mucositis prophylactic application (MPA) group with control, 2. Mucositis therapeutic application (MTA) group with control and 3. Dermatitis therapeutic application (DTA) group with control. Prophylactic application of drug consisted of spraying the Gene Time preparation on the irradiated skin or mucous membrane as radiotherapy was being carried out. This was compared with control patients who received routine conventional skin care. Therapeutic application was started as grade I radiation mucositis or dermatitis appeared. The evaluation of acute radiation mucositis and dermatitis was done according to the systems proposed by RTOG or EORTC. Results: The results showed that in the MPA group, the rate of radiation mucositis at ≤10 Gy was 20% (4/20) as compared to the 70% (14/20) of the control (P = 0.004). During the course of radiation, the incidences of grade III, IV acute radiation mucositis and dermatitis were always lower than the control. In therapeutic application of Gene Time, the response rate of acute radiation mucositis was also better than the control (90% vs 50%) (P = 0.016) and that of acute dermatitis was similar (95% vs 50%) (P = 0.005). Moreover, the ≤3 d rate of healing of grade III dermatitis in the application group was 3/7 as compared to the 0/14 of the control. Conclusion: Prophylactic application of recombinant human epidermal growth factor is able to postpone the development of radiation mucositis. This preparation is also able to lower the incidence of grade III, IV mucositis and dermatitis both by therapeutic and prophylactic application in addition to the hastened healing of grade III dermatitis

Previous reports suggest that atopic dermatitis is more common in black Caribbean children born in the United Kingdom than in white children. It is unclear whether these differences are caused by selection bias or variations in the use of the word "eczema" in the groups studied. Our objective was to explore ethnic group differences in the prevalence of atopic dermatitis in London schoolchildren. A cross-sectional prevalence survey of 693 junior school children in three schools was performed. Atopic dermatitis was defined in three ways: (1) by a dermatologist, (2) by visible flexural dermatitis as recorded by an independent observer, and (3) by a history of flexural dermatitis according to the child's parents. The prevalence of atopic dermatitis according to examination by a dermatologist was 16.3% in black Caribbean children and 8.7% in white children. This increased risk was present for different methods of defining of a atopic dermatitis and persisted after adjustment for potential confounders. London-born black Caribbean children appear to be at an increased risk of having atopic dermatitis.

Reena Rai

2016-01-01

Full Text Available Background: The photopatch test is used to detect photoallergic reactions to various antigens such as sunscreens and drugs. Photosensitive dermatitis can be caused due to antigens like parthenium, fragrances, rubbers and metals. The photopatch test does not contain these antigens. Therefore, the Indian Standard Series (ISS along with the Standard photopatch series from Chemotechnique Diagnostics, Sweden was used to detect light induced antigens. Aim: To detect light induced antigens in patients with photosensitive dermatitis. Methods: This study was done in a descriptive, observer blinded manner. Photopatch test and ISS were applied in duplicate on the patient's back by the standard method. After 24 hours, readings were recorded according to ICDRG criteria. One side was closed and other side irradiated with 14 J/cm2 of UVA and a second set of readings were recorded after 48 hrs. Result: The highest positivity was obtained with parthenium, with 18 out of 35 (51% patients showing a positive patch test reaction with both photoallergic contact dermatitis and photoaggravation. Four patients (11% showed positive patch test reaction suggestive of contact dermatitis to potassium dichromate and fragrance mix. Six patients had contact dermatitis to numerous antigens such as nickel, cobalt, chinoform and para-phenylenediamine. None of these patients showed photoaggravation on patch testing. Conclusion: Parthenium was found to cause photoallergy, contact dermatitis with photoaggravation and contact allergy. Hence, photopatch test and UV irradiated patch test can be an important tool to detect light induced antigens in patients with photosensitive dermatitis.

Considering the early onset of atopic dermatitis (AD), which most often arises in the first year of life, risk factors occurring very early in life must be considered. Little is known about the effects of maternal occupational exposure on the development of atopic disorders in children. The aim of this study was to evaluate associations between maternal employment and childhood AD. We used multistage stratified systematic sampling to recruit 24,200 mother-newborn pairs from the Taiwan national birth register. Information on maternal occupation categories, work stress, working time, shift work and potential confounders during pregnancy was gathered by questionnaires after birth. At 3 years of age, information on the development of AD was assessed by home interviews. Multiple logistic regression analysis was performed to estimate the association of maternal employment and AD. Overall, 11,962 out of 19,381 mothers (61·7%) worked during pregnancy. The children of mothers who worked during pregnancy had an increased risk of AD compared with those whose mothers did not work [odds ratio (OR) 1·38, 95% confidence interval (CI) 1·25-1·53]. The children of mothers with a professional or technical occupation had a higher risk of AD (OR 1·64, 95% CI 1·44-1·87). The risk of AD was found to increase with maternal work stress during pregnancy in a dose-response manner (P(trend)maternal shift work was found. Working in professional or technical occupations increased the risk of childhood AD in addition to work stress during pregnancy. © 2013 The Authors. BJD © 2013 British Association of Dermatologists.

Saffron, a bulbous perennial plant belonging to Iridaceae family, is the most expensive cultivated herb that is widely used for industrial and nonindustrial purposes. However, besides its attractive and valuable properties, contact dermatitis due to saffron is an uncommon reported entity. The aims of this study were to determine the clinical pattern patch-testing profile of contact dermatitis in saffron workers and to identify the most common allergens/sensitizers. One hundred ten saffron workers were patch-tested with 39 allergens, which included Indian standard series antigens, plant series antigens, and extracts from different parts of saffron flower. The allergens in Indian standard series accounted for 52.44% of positive reactions. Plant series and different parts of saffron accounted for 47.56% of the positive reactions. Among those patients with positive responses to the supplemental saffron allergens, 83.3% were of present or past relevance. The data observed in the present study confirm that the saffron dermatitis is a distinct clinical entity with characteristic clinical presentation and has a strong significance as an occupational allergen in those handling this plant. Patch testing with different parts of saffron flower has a role to play in finding out the etiological cause.

Full Text Available Background: The contact allergic reactions from p-phenylenediamine (PPD in hair dyes vary from mild contact dermatitis to severe life- threatening events (angioedema, bronchospasm, asthma, renal impairment. Objectives: To study the clinical patterns and PPD contact sensitivity in patients with hair-dye dermatitis. Materials and Methods: Eighty (M: F 47:33 consecutive patients aged between 18 and 74 years suspected to have contact allergy from hair dye were studied by patch testing with Indian Standard Series including p-phenylenediamine (PPD, 1.0% pet. Results: 54 Fifty-four (M: F 21:33 patients showed positive patch tests from PPD. Eight of these patients also showed positive patch test reaction from fragrance mix, thiuram mix, paraben mix, or colophony. Fifty-seven (71% patients affected were aged older than 40 years. The duration of dermatitis varied from 1 year with exacerbation following hair coloring. Forty-nine patients had dermatitis of scalp and/or scalp margins and 23 patients had face and neck dermatitis. Periorbital dermatitis, chronic actinic dermatitis, and erythema multiforme-like lesions were seen in 4, 2, and 1 patients, respectively. Conclusions: Hair dyes and PPD constitute a significant cause of contact dermatitis. There is an urgent need for creating consumer awareness regarding hair-dyes contact sensitivity and the significance of performing sensitivity testing prior to actual use.

Recurrent or persistent follicular dysplasia and interface dermatitis are described in nine Boxers. Data on age, sex, seasonality of alopecia and histopathological features of the follicular dysplasia in these nine Boxers are comparable with those described in previous reports. The interface dermatitis was characterized by multifocal annular crusted lesions confined to the areas of follicular dysplasia. The inflammatory lesions were neither pruritic nor painful and affected dogs were otherwise healthy. Histopathologically the clinically inflammatory lesions were characterized as an interface dermatitis. Immunohistochemical studies failed to demonstrate immunoglobulins or complement at the basement membrane zone or within blood vessel walls. In dogs with recurrent or persistent disease, the follicular dysplasia and interface dermatitis ran identical, concurrent courses of spontaneous remission and recurrence, or persistence, respectively. One dog with persistent disease was treated successfully with tetracycline and niacinamide for the interface dermatitis, and melatonin for the follicular dysplasia. Although the aetiopathogenesis of this newly described condition and the relationship between the two histological reaction patterns are not known, photoperiod and genetic predisposition appear to play a role.

Allergic Contact Dermatitis Induced by Textile Necklace

2013-11-01

Full Text Available Allergic contact dermatitis to textile dyes is considered to be a rare phenomenon. A recent review reported a prevalence of contact allergy to disperse dyes between 0.4 and 6.7%. The relevance of positive patch testing was not reported in all studies. Textile dye allergy is easily overlooked and is furthermore challenging to investigate as textile dyes are not labelled on clothing. In this report, we present a case of allergic contact dermatitis to a textile necklace. The patch test showed strong reactions to the necklace and the azo dyes Disperse Orange 1 and Disperse Yellow 3. Despite the European legislation and the reduced use of disperse dyes in Third World countries, disperse azo dyes still induce new cases of allergic contact dermatitis.

Early diagnosis and treatment of occupational medicamentosa-like dermatitis due to trichloroethylene (OMLDT) are absence of specific and reliable diagnostic/therapeutic biomarkers. This study was conducted on 30 cases of OMLDT, 58 workers exposed to trichloroethylene (TCE) and 40 unexposed controls in order to identify any cytokine signatures that give an index to CD4 + T cell differential and serve as biomarkers of OMLDT. Expression profiles of Th 1 , Th 2 , Th 17 and Treg cell type-specifying transcription factors and cytokines were analyzed using real time quantitative PCR (RT-qPCR) assay. To explore whether such expression profiles reflected their steady state plasma levels, a Luminex liquid fluorescence analysis was conducted. We found that the expression of transcription factors FoxP3 transcription factors (P = 0.006 and P < 0.0001) and IL-10 cytokine (P = 0.0008 and P < 0.0001) of the Treg subset were significantly higher in patients than TCE exposure workers and unexposed controls, suggesting that Treg cells were active after the occurrence of OMLDT. The transcript levels of IL-6 were significantly lower in the TCE exposure groups including patients and exposure workers as compared to the unexposed controls (P < 0.0001 and P = 0.0008). Circulating levels of assessed cytokines of IL-6 (P = 0.001 and P = 0.011) and TFN-α (P = 0.005 and P < 0.0001) were lower in the exposure groups than in the unexposed controls. Compared to the controls, the levels of IL-10 in patients were higher (P = 0.001 and P = 0.0008). There was a significantly positive correlation between the plasma levels IL-6 and IL-10 in TCE exposed workers. These alterations in the expression of transcription factors and cytokines highlight the underlying dysregulation of T cell subsets in OMLDT that reflect an immune tolerance or immune inhibition. Therefore, the elevation of IL-10 level may be a kind of pathogenesis indicator, and the decline in IL

2004-10-01

Full Text Available Abstract Background We sought to elicit preference weights from parents for health states corresponding to children with various levels of severity of atopic dermatitis. We also evaluated the hypothesis that parents with children who had been diagnosed with atopic dermatitis would assign different preferences to the health state scenarios compared with parents who did not have a child with atopic dermatitis. Methods Subjects were parents of children aged 3 months to 18 years. The sample was derived from the General Panel, Mommies Sub-Panel, and Chronic Illness Sub-Panel of Harris Interactive. Participants rated health scenarios for atopic dermatitis, asthma, and eyeglasses on a visual analog scale, imagining a child was experiencing the described state. Results A total of 3539 parents completed the survey. Twenty-nine percent had a child with a history of atopic dermatitis. Mean preference scores for atopic dermatitis were as follows: mild, 91 (95% confidence interval [CI], 90.7 to 91.5; mild/moderate, 84 (95%CI, 83.5 to 84.4; moderate, 73 (95%CI, 72.5 to 73.6; moderate/severe, 61 (95%CI, 60.6 to 61.8; severe, 49 (95% CI, 48.7 to 50.1; asthma, 58 (95%CI, 57.4 to 58.8; and eyeglasses, 87(95%CI, 86.3 to 87.4. Conclusions Parents perceive that atopic dermatitis has a negative effect on quality of life that increases with disease severity. Estimates of parents' preferences can provide physicians with insight into the value that parents place on their children's treatment and can be used to evaluate new medical therapies for atopic dermatitis.

Facial dermatitis is commonly encountered in dermatologic practice. It is sometimes difficult to manage because its causative factors may be multiple and difficult to diagnose. This study was designed to identify the characteristics, patch test results, and final diagnoses of facial dermatitis patients who were referred to a contact dermatitis clinic and to identify factors associated with facial allergic contact dermatitis (ACD). We retrospectively reviewed case records of facial dermatitis patients who underwent patch testing at the clinic during the period from July 2006 to June 2011. Of the 891 patients patch-tested, 244 (27.4%) had facial dermatitis. Female patients were 9.1 times more predominant than male patients. The mean ± standard deviation age of patients was 37.3 ± 14.8 years. A total of 199 (81.6%) patients demonstrated at least one positive reaction to a patch test, 66.7% of which were clinically relevant. Allergic contact dermatitis was diagnosed in 45.5% of patients. Independent factors predisposing towards facial dermatitis were female sex, having a previous history of cosmetic allergy, a positive patch test reaction to hairdressing product-related allergens, and a positive allergic reaction to preservative allergens. The prevalence of facial dermatitis was 27.4%. Almost half of all patients with facial dermatitis demonstrated ACD. Factors associated with facial ACD were female gender, a history of cosmetic allergy, and positive patch test reactions to hairdressing product-related allergens and preservatives. © 2015 The International Society of Dermatology.

Parthenium dermatitis severity score to assess clinical severity of disease

Kaushal K Verma

2017-01-01

Full Text Available Background: Parthenium dermatitis is the most common type of airborne contact dermatitis in India. It is a chronic disease of a remitting and relapsing course with significant morbidity and distress, but there is no scoring system to assess its severity. Aim: To design a scoring system for the assessment of clinical severity of disease in Parthenium dermatitis and to use this scoring system in various studies to determine its sensitivity, specificity, and reproducibility. Methods and Results: In our first few studies on Parthenium dermatitis, we designed and used a basic clinical severity scoring system based on itching, morphology of the lesions, and areas involved. However, in subsequent studies, we modified it to the present scoring system as Parthenium dermatitis severity score (PDSS. Our studies showed the high sensitivity of PDSS in characterization of the disease severity at the given point of time, as well as to determine the efficacy of a prescribed treatment modality which was reliable and reproducible. Conclusion: Thus, PDSS may be used by clinicians for appropriate scoring of the clinical severity of Parthenium dermatitis and in monitoring the disease response to therapy.

Fragrances are a common cause of allergic contact dermatitis in Europe and in North America. They can affect individuals at any age and elicit a spectrum of reactions from contact urticaria to systemic contact dermatitis. Growing recognition of the widespread use of fragrances in modern society has fueled attempts to prevent sensitization through improved allergen identification, labeling, and consumer education. This review provides an overview and update on fragrance allergy. Part 1 discusses the epidemiology and evaluation of suspected fragrance allergy. Part 2 reviews screening methods, emerging fragrance allergens, and management of patients with fragrance contact allergy. This review concludes by examining recent legislation on fragrances and suggesting potential additions to screening series to help prevent and detect fragrance allergy.

Esomeprazole-induced photoallergic dermatitis

2010-01-01

Full Text Available There are no published case reports of esomeprazole-induced photoallergic dermatitis. We report here a 58-year-old lady with prior history of propylthiouracil and carbimazole-induced photoallergy, who presented with heartburn and dysphagia. She was diagnosed to have erosive esophagitis and was treated with esomeprazole, following which she developed photoallergic dermatitis. It improved on cessation of the drug and did not recur on subsequent treatment with ranitidine. Naranjo score for this adverse drug event was 8, thereby making it a probable adverse drug reaction. This reaction may be due to sulphur moiety, which is common to all these drugs. Physicians must be aware of this possible side-effect, especially in patients with prior history of photoallergy to other drugs.

The term atopic dermatitis (AD) is commonly used in cats. At present, however, there is little known about the pathogenesis of feline AD. The aim was to investigate various aspects of the immunopathogenesis in a defined group of cats with signs and symptoms of atopic dermatitis and compare our findings with the immunoregulation of atopic dermatitis in humans. The presence of antigen-specific IgE in serum of AD cats was investigated by means of the Prausnitz-Küstner (PK) test and the passive c...

Evaluation and Management of Patch Test-Negative Patients With Generalized Dermatitis.

Science.gov (United States)

Spiker, Alison; Mowad, Christen M

Patients with generalized dermatitis are common in dermatology practices. Allergic contact dermatitis is often suspected, and patients frequently undergo patch testing. When the patch testing result is negative, further evaluation and management of these patients are challenging. The purpose of this study was to survey members of the American Contact Dermatitis Society regarding the evaluation and management of patch test-negative patients with generalized dermatitis. Generalized dermatitis was the most common term identified for patch test-negative patients with diffuse dermatitis. After having negative expanded patch testing results, most physicians proceeded with additional testing including skin biopsy, complete blood cell count with differential, and liver and renal function tests. The most commonly used systemic treatment is prednisone, followed by methotrexate. Narrow-band ultraviolet B (UVB) is the most commonly used light source. Antihistamines are frequently prescribed. Food allergy is not felt to be causative. This cohort of patients experiences significant impairment in quality of life, stress on personal relationships, and time off work. The management of patch test-negative patients with generalized dermatitis is challenging. This study provides insight into management of these complex patients. It also demonstrates practice gaps in the management of these patients, indicating a need for further studies to direct the evaluation and management of this patient population.

The role of antiseptic agents in atopic dermatitis.

Science.gov (United States)

Lee, Melissa; Van Bever, Hugo

2014-10-01

The skin of individuals with atopic dermatitis has a susceptibility to be colonized with Staphylococcus aureus. This has been associated with increased frequency and severity of exacerbations of atopic dermatitis. Therefore, there is a growing interest in the use of antiseptic agents to target primary bacterial colonization and infection. Antiseptic agents have been found to be better tolerated and less likely to induce bacterial resistance as compared to antibiotics. There is also a wide variety of antiseptic agents available. The efficacy of antiseptic agents has yet to be established as the studies reviewed previously have been small and of suboptimal quality. This review discusses the rationale behind targeting S. aureus with antiseptic agents and presents findings from a review of studies assessing the efficacy of antiseptics in atopic dermatitis in the last five years. Four studies were found, including a bleach bath study which has already been reviewed elsewhere. The remaining 3 studies assessed the efficacy of sodium hypochlorite containing cleansing body wash, sodium hypochlorite baths and 1% triclosan in leave on emollient. These studies suggested some benefit for the inclusion of antiseptic use with the mainstay management of atopic dermatitis, including a potential steroid sparring effect. However, there are many limitations to these studies which therefore warrant further investigation on the impact of antiseptic use in atopic dermatitis.

Contact dermatitis can be defined as an inflammatory process affecting the skin surface and induced by contact with chemical, physical and/or biotic agents in the environment. It causes lesions to skin, mucosae and semi-mucosae by means of allergic and irritant pathogenic mechanisms. Among the main triggers of contact dermatitis in the pediatric age are chemical or physical agents, which cause irritant contact dermatitis (ICD), and sensitizers, which cause a tissue damage through an allergic mechanism (allergic contact dermatitis [ACD]). A prospective, multicenter, observational study was carried out in 204 children affected by contact dermatitis, aged up to 14 years, and enrolled by pediatricians from 7 different Italian provinces. The diagnosis of contact dermatitis was based on the pediatrician's clinical evaluation. The data were collected through a series of simple and multiple choice questions, anonymously filled out by pediatricians. In 90% of cases (184 of 204 patients), there was complete remission of contact dermatitis, with no cases of worsening. No adverse events were observed, either. The effectiveness of the therapy was rated as "very effective" by 84.4% of the parents and 86.8% of the pediatricians. In only 10 patients a new therapy had to be prescribed. Contact dermatitis is a heterogeneous inflammatory skin disease induced by contact with different kinds of environmental agents. Cutaneous manifestations are highly variable and depend on the modality of contact, on the causative agent and on the pathogenesis. This Italian experience of a clinical approach to contact dermatitis stresses the need of daily skin care through different therapeutic strategies, based on the diagnosis, the clinical severity and the parents and children compliance. The first therapeutic measure to be implemented is prevention, through the removal of the causative agent and the use of protective devices. Indeed, preserving the skin's barrier function is an important goal and

[Atopic dermatitis and domestic animals].

Science.gov (United States)

Song, M

2000-09-01

Several arguments are raised attributing to aeroallergens an important role in atopic dermatitis. The aeroallergens that penetrate the epidermis could be fixed by IgE on the Langerhans cells and then induce a cellular mediator reaction comparable to that of allergic contact eczema. Patch tests have been developed to evaluate the role of aeroallergens (dust mites, animal dander, etc.). Preventive anti-dust mites measures in the home of atopic patients are recommended. Eviction of domestic animals (cat, dog, etc.) or avoidance measures for animal dander in the home can produce improvement in atopic dermatitis. Oral specific immunotherapy is being validated as a treatment for this disease.

Vitamin D in Atopic Dermatitis, Chronic Urticaria and Allergic Contact Dermatitis

Quirk, Shannon K; Rainwater, Ellecia; Shure, Anna K; Agrawal, Devendra K

2016-01-01

Summary Vitamin D influences allergen-induced pathways in the innate and adaptive immune system, and its potential immunomodulatory role in allergic skin disorders has been explored. This comprehensive review article provides an overview of the role of vitamin D in three common dermatologic conditions: atopic dermatitis (AD), chronic urticaria, and allergic contact dermatitis (ACD). Whereas the literature regarding vitamin D and AD has resulted in mixed findings, several studies have described an inverse relationship between vitamin D levels and AD severity, and improvement in AD with vitamin D supplementation. Similarly, several studies report an inverse relationship between vitamin D levels and severity of chronic urticaria. Although current research in humans remains limited, an increased likelihood of ACD has been demonstrated in vitamin D-deficient mice. Additional well-designed clinical trials will be necessary to determine whether vitamin D supplementation should be recommended for prevention or adjuvant treatment of these common dermatologic conditions.

Education about therapy applies to many chronic diseases. The aim is to improve patient management through the development of certain skills by patients themselves. Atopic dermatitis is an area amenable to the development of therapeutic education. The purpose of this study was to define the skills required for management of atopic dermatitis suitable for therapeutic education and to bring together these skills in a handbook suitable for use. Thirty caregivers were involved in the drafting of the handbook (dermatologists, a doctor specialising in therapeutic education, a psychologist and nurses), each of whom has experience of therapeutic education in atopic dermatitis. Four age groups were selected (under 5 years, 6 to 10 years, pre-teens/adults, parents of children aged under 5 years). For each age group, different levels of skill were identified for patients or parents of children and suitable learning methods were selected. Skills were classed according to 3 levels: (i) knowledge about the disease, treatments, triggering factors, (ii) knowledge about provision of care by patients or their parents, (iii) knowledge in terms of explaining the disease and treatment methods to family, and knowing who to contact and when. Finally, a 10-question evaluation guide was drawn up. In this paper we report the method of production and content of the handbook of skills for atopic dermatitis patients. The aim is not to impose all skills listed in this work on patients but rather to provide caregivers with a complete handbook covering therapeutic education. The book is intended for patients with moderate to severe forms of atopic dermatitis currently in therapeutic failure. It may be used by anyone treating such patients, whether doctors, nurses or psychologists, depending on the items chosen. It is intended for use as a support for the elaboration, diffusion and evaluation of a therapeutic education programme for atopic dermatitis.

Avian Schistosomes and Outbreaks of Cercarial Dermatitis

SUMMARY Cercarial dermatitis (swimmer's itch) is a condition caused by infective larvae (cercariae) of a species-rich group of mammalian and avian schistosomes. Over the last decade, it has been reported in areas that previously had few or no cases of dermatitis and is thus considered an emerging disease. It is obvious that avian schistosomes are responsible for the majority of reported dermatitis outbreaks around the world, and thus they are the primary focus of this review. Although they infect humans, they do not mature and usually die in the skin. Experimental infections of avian schistosomes in mice show that in previously exposed hosts, there is a strong skin immune reaction that kills the schistosome. However, penetration of larvae into naive mice can result in temporary migration from the skin. This is of particular interest because the worms are able to migrate to different organs, for example, the lungs in the case of visceral schistosomes and the central nervous system in the case of nasal schistosomes. The risk of such migration and accompanying disorders needs to be clarified for humans and animals of interest (e.g., dogs). Herein we compiled the most comprehensive review of the diversity, immunology, and epidemiology of avian schistosomes causing cercarial dermatitis. PMID:25567226

From a clinical point of view, the prevalence of allergic contact dermatitis (ACD) among children and adolescents seems to be low. However, many children have dermatitis, most often atopic dermatitis. In selected cases, ACD is suspected, and the child is tested. The question remains, whether...... the prevalence of ACD in children really is low or whether the possibility of ACD is not sufficiently considered. During the last decade, reports have appeared on series of children and adolescents with contact allergy and ACD. Few cases have been reported in infants, but the development of contact allergy...... and ACD increases with age. Most studies include selected groups of children and adolescents with suspected ACD. Few studies have examined unselected populations, and most consider only the prevalence of contact allergy without evaluating the clinical relevance, e.g., the prevalence of ACD. Furthermore...

Grey, Katherine R; Warshaw, Erin M

Allergic contact dermatitis is an important cause of periorbital dermatitis. Topical ophthalmic agents are relevant sensitizers. Contact dermatitis to ophthalmic medications can be challenging to diagnose and manage given the numerous possible offending agents, including both active and inactive ingredients. Furthermore, a substantial body of literature reports false-negative patch test results to ophthalmic agents. Subsequently, numerous alternative testing methods have been described. This review outlines the periorbital manifestations, causative agents, and alternative testing methods of allergic contact dermatitis to ophthalmic medications.

Lymphomatoid contact dermatitis is a pseudolymphoma with clinical and histological features of allergic contact dermatitis and cutaneous T cell lymphoma. Incorrect diagnosis may lead to unnecessary testing, unnecessary treatment, or patient harm. The objective of this study is to present a case to demonstrate the diagnostic challenge and overlap between allergic contact dermatitis and cutaneous T cell lymphoma in a patient with lymphomatoid contact dermatitis caused by methylchoroisothiazolinone/methylisothiazolinone and paraben mix, and to review the existing literature in order to summarize the demographics, clinical features, allergens and treatments reported for lymphomatoid contact dermatitis. A search of major scientific databases was conducted for English-language articles reporting cases of lymphomatoid contact dermatitis or additional synonymous search headings. Nineteen articles with a total of 23 patients were analysed. Lymphomatoid contact dermatitis was more common in men, with an average age of 58.5 years. Fourteen unique allergens were identified and confirmed by patch testing. However, no single test or study was diagnostic of lymphomatoid contact dermatitis. Allergen avoidance was the most useful management tool, but selected patients required topical or systemic immunosuppression. In conclusion, without specific diagnostic features, evaluation for lymphomatoid contact dermatitis should include a thorough history and examination, patch testing, and biopsy with immunohistochemistry and clonality studies. © 2014 John Wiley & Sons A/S.

Atopic dermatitis is an inflammatory skin disease that frequently affects children. The current recommendations on management using lifestyle modification are highly variable, leading to confusion and uncertainty among patients. To determine current bathing behaviors and the subsequent impact on disease severity. This was an observational cross-sectional study conducted at an urban pediatric emergency department. Parents were asked to fill out a questionnaire concerning the patient's bathing habits. The results were correlated with the atopic dermatitis severity determined by the SCORAD (SCORing Atopic Dermatitis) tool. No difference between variables was found to be significant for bathing frequency, time spent bathing, or use of moisturizers. Multivariate analysis showed that atopic dermatitis severity increased with age greater than 2 years (P = .0004) and with greater bathing duration (P = .001). Atopic dermatitis severity may be associated with a longer duration of bathing. The frequency of bathing does not appear to affect atopic dermatitis severity. © The Author(s) 2015.

IL-31 is a cytokine that is believed to play an important role in atopic dermatitis (AD). IL-31 levels positively correlate with disease severity in children with AD. Currently, there is no study that has investigated such a correlation in atopic dogs. The purpose of this study was to evaluate the correlation between IL-31 serum levels and severity of dermatitis. It was hypothesized that a positive correlation exists between severity of AD and circulating levels of IL-31. Sixteen atopic beagles experimentally sensitized to house dust mites. Atopic beagles were exposed to dust mites epicutaneously twice weekly for four weeks. Severity of dermatitis was scored by the Canine Atopic Dermatitis and Extent Severity Index, 3 rd iteration (CADESI-03) on days 0 and 28. Blood samples were taken on days 0 and 28 to measure serum IL-31 using a commercially available ELISA. Correlation between CADESI-03 scores and serum IL-31 levels was not detected on day 0 (Pearson, r = -0.2609, P = 0.3291). After flare-up of dermatitis was induced with allergen exposure, a significant positive correlation was detected between serum IL-31 and CADESI-03 on Day 28 (r = 0.6738, P = 0.004). Positive correlation was detected in active disease between severity of dermatitis and circulating levels of IL-31. Additional studies are needed to investigate this correlation in other breeds of dogs and to test whether circulating levels of IL-31 may predict clinical response to biological agents aimed at IL-31. © 2017 ESVD and ACVD.

The history of atopic dermatitis.

Kramer, Owen N; Strom, Mark A; Ladizinski, Barry; Lio, Peter A

Fred Wise (1881-1950) and Marion Sulzberger (1895-1983) are often credited with introducing the term atopic dermatitis to dermatology in 1933. This definition was based on atopy, a term first created by Arthur Coca (1875-1959) and Robert Cooke (1880-1960) in 1923, when they recognized an association between allergic rhinitis and asthma. Despite its recent introduction into our medical lexicon, historical precursors of atopic dermatitis date back to at least as early as 69-140 ce. In this contribution, we highlight both the prominent individuals credited with shaping the disorder into our current interpretation and the suspected historical precursors of this disease and reported treatments.

Objective: To determine the prevalence of ACD in atopics in comparison to non-atopics in our community. Design: Cross sectional study. Place and Duration of Study: Departments of Dermatology, King Edward Medical College/Mayo Hospital, Lahore, from May 1998 to July 1999. Subjects and Methods: Two hundred and fifty patients, 34 with past or present atopic dermatitis (Group I), 88 with personal or familial atopy (Group II) and 128 non-atopic with contact dermatitis (Group III) were subjected to patch testing with European standard series. The results were interpreted according to International Contact Dermatitis Research Group guidelines. Results: Positive reactions were seen in 50%, 70.4% and 67.8% of patients in the respective groups (p>0.05). Conclusion: Our results suggest that atopics are equally affected with contact dermatitis as compared with non-atopics and recalcitrant cases of atopic dermatitis should be patch tested to find out aggravating factors.

Peristomal dermatitis is a common complication for the >700 000 patients in the United States with an ostomy. The role of stoma skin care products in peristomal dermatitis is poorly understood. To evaluate stoma skin care products as a cause of peristomal dermatitis. A retrospective chart review of patients with peristomal dermatitis at four academic hospitals from January 2010 to March 2014 was performed. Patient demographics, clinical information and use test and patch test results were documented. Eighteen patients identified as having peristomal dermatitis were tested. Twelve of these had peristomal contact dermatitis. We identified numerous stoma skin care products as triggers of irritant and/or allergic contact dermatitis. The most common stoma skin care product used and/or involved in dermatitis was Cavilon™ No Sting Barrier Film. Our data support a paradigm shift whereby healthcare workers treating patients with peristomal dermatitis, which is currently considered to be a reaction mainly to bodily fluids, must consider those products used to protect the skin as potential triggers for this disease. Therefore, patients with peristomal dermatitis should be tested with their stoma skin care agents to determine the need for removal or change of these products. Additionally, full ingredient labelling by manufacturers would help identify new allergens and irritants. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Immunotherapy of allergic contact dermatitis.

Science.gov (United States)

Spiewak, Radoslaw

2011-08-01

The term 'immunotherapy' refers to treating diseases by inducing, enhancing or suppressing immune responses. As allergy is an excessive, detrimental immune reaction to otherwise harmless environmental substances, immunotherapy of allergic disease is aimed at the induction of tolerance toward sensitizing antigens. This article focuses on the historical developments, present state and future outlook for immunotherapy with haptens as a therapeutic modality for allergic contact dermatitis. Inspired by the effectiveness of immunotherapy in respiratory allergies, attempts were undertaken at curing allergic contact dermatitis by means of controlled administration of the sensitizing haptens. Animal and human experiments confirmed that tolerance to haptens can be induced most effectively when the induction of tolerance precedes attempted sensitization. In real life, however, therapy is sought by people who are already sensitized and an effective reversal of hypersensitivity seems more difficult to achieve. Decades of research on Rhus hypersensitivity led to a conclusion that immunotherapy can suppress Rhus dermatitis, however, only to a limited degree, for a short period of time, and at a high risk of side effects, which makes this method therapeutically unprofitable. Methodological problems with most available studies of immunotherapy of contact allergy to nickel make any definite conclusions impossible at this stage.

Full Text Available Atopic dermatitis (AD is one of the most common allergic diseases in children which is assuming ever greater medical and social importance. Risk factors of AD include gastro-intestinal tract disturbances, especially intestinal dysbiosis, which is revealed in 89–94,1% of children with atopic dermatitis. Both correlation of the dysbiosis and AD manifestations severity and increase of underlying disease treatment efficacy as a result of target influence on intestinal microflora confirm that. For many decades guidelines of atopic dermatitis treatment in children along with elimination diet, antihistamine drugs and topic medicines include enterosorbents. The most effective drugs are those ones, consisting of prebiotics and sorbents. The wide experience of prebiotic drug with sorbent action (Lactofiltrum in complex therapy of atopic dermatitis in children is reviewed in this article.

Autoimmune Progesterone Dermatitis Presenting as Stevens-Johnson Syndrome.

Drayer, Sara M; Laufer, Larry R; Farrell, Maureen E

2017-10-01

Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of her symptoms was noted, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge. After 48 months, she remained refractory to medical management and definitive surgical treatment with bilateral oophorectomy was performed. Autoimmune progesterone dermatitis is a challenging diagnosis owing to its rarity and variety of clinical presentations. Treatment centers on suppression of endogenous progesterone and avoidance of exogenous triggers. When these modalities fail, surgical management must be undertaken.

Contact dermatitis is a common dermatologic condition that can cause significant impairment in patients' overall quality of life (QoL). This impact is separate and potentially more clinically relevant than one's disease "severity" in contact dermatitis and should be consistently addressed by dermatologists. Despite this, QoL tools specific to contact dermatitis are lacking, and there is little consistency in the literature regarding the tool used to evaluate clinical response to therapies. Measurements currently available to evaluate disease-related QoL in contact dermatitis fit into 1 of the following 3 general types: generic health-related QoL measures, dermatology-related QoL measures, or specific dermatologic disease-related QoL measures. This article reviews the strengths and weaknesses of existing QoL tools used in contact dermatitis including: Short Form Survey 36, Dermatology Life Quality Index, Skindex-29, Skindex-16, Dermatology-Specific Quality of Life, and Fragrance Quality of Life Index.

Eyelid Dermatitis: Contact Allergy to 3-(Dimethylamino)propylamine

Science.gov (United States)

Knopp, Eleanor; Watsky, Kalman

2014-01-01

We present the case of a 42-year-old woman with intractable eyelid dermatitis. Patch testing revealed sensitization to 3-(dimethylamino)propylamine (DMAPA). DMAPA is an important etiology of allergic contact dermatitis of the eyelids and face but is easily missed even with expanded-series patch testing. We also review the most common causative allergens in eyelid dermatitis cited in the literature over the past decade. DMAPA is a reagent used in the formation of cocamidopropyl betaine (CAPB), a common additive to liquid soaps, shampoos, and other cleansing products because of its utility as a surfactant. Beginning in the 1980s, reports of allergy to CAPB surfaced in the literature. Ultimately, a majority of patch testing studies have shown that clinical allergy to CAPB-containing products actually reflects allergy to contaminant DMAPA in most cases. Amidoamine, another intermediate in the formation of CAPB, may also be implicated through a proposed mechanism of conversion to DMAPA in the skin. When patch-testing for eyelid and facial dermatitis, it is crucial to test with DMAPA directly, not just with CAPB; unlike commercial-grade CAPB, the CAPB in patch test kits is ultrapure and does not contain contaminant DMAPA.

Hand dermatitis associated fingerprint changes is a significant problem and affects fingerprint verification processes. This study was done to develop a clinically useful prediction model for fingerprint verification in patients with hand dermatitis. A case-control study involving 100 patients with hand dermatitis. All patients verified their thumbprints against their identity card. Registered fingerprints were randomized into a model derivation and model validation group. Predictive model was derived using multiple logistic regression. Validation was done using the goodness-of-fit test. The fingerprint verification prediction model consists of a major criterion (fingerprint dystrophy area of ≥ 25%) and two minor criteria (long horizontal lines and long vertical lines). The presence of the major criterion predicts it will almost always fail verification, while presence of both minor criteria and presence of one minor criterion predict high and low risk of fingerprint verification failure, respectively. When none of the criteria are met, the fingerprint almost always passes the verification. The area under the receiver operating characteristic curve was 0.937, and the goodness-of-fit test showed agreement between the observed and expected number (P = 0.26). The derived fingerprint verification failure prediction model is validated and highly discriminatory in predicting risk of fingerprint verification in patients with hand dermatitis. © 2014 The International Society of Dermatology.

2009-03-02

Devriesea agamarum is frequently isolated from dermatitis in lizards, notably from cheilitis in spiny tailed lizards (genus Uromastyx). It was the aim of the present study to assess the role of this bacterium as a causative agent of dermatitis by fulfilling Koch's postulates. First, its association with diseased lizards was demonstrated. The bacterium was isolated from several, mainly desert dwelling squamate species showing symptoms of dermatitis and/or septicaemia. The affected lizards mainly belonged to the family of the Agamidae (genera Pogona, Uromastyx, Agama) and in one case to the Iguanidae (genus Crotaphytus). Secondly, the occurrence of D. agamarum in 66 clinically healthy bearded dragons, 21 clinically healthy Uromastyx species and 40 squamate eggshells was studied. The bacterium was isolated from the oral cavity of 10 bearded dragons but from none of the healthy Uromastyx species. Hence D. agamarum was found to be part of the oral microbiota in Pogona vitticeps. Finally, bearded dragons (P. vitticeps) were experimentally inoculated with D. agamarum by direct application of a bacterial suspension on intact and abraded skin. At the scarified skin of all inoculated lizards, dermatitis was induced from which D. agamarum was re-isolated. In conclusion, D. agamarum is a facultative pathogenic bacterium, able to cause dermatitis in agamid lizards when the integrity of the skin is breached.

The pediatric rheumatology is a medical specialization with many areas under developed. The prevalence, pathophysiology and form of presentation of the pediatric rheumatic disease are different of adults. The skin compromise in many pediatric rheumatic diseases is a helping sing for diagnosis. The arthritis-dermatitis syndrome can be the first manifestation of many diseases as infections, tumors and endocrine diseases, but in pediatric age the immunologic and infections diseases are really important. Among infections diseases, virus (parvovirus, rubella, HIV) and bacteria (gonococcus, meningoccus) are the most Important. Within the group of autoimmune diseases the vasculitis such as Henoch-Schonlein purpura and Kawasaki disease are among the more prevalent autoimmune disease. This is a general review about arthritis-dermatitis syndrome in pediatric age

Occupational dermatoses in the uranium mining and processing industry

Energy Technology Data Exchange (ETDEWEB)

Sevcova, M [Zavodni Ustav Narodniho Zdravi Uranoveho Prumyslu, Pribram (Czechoslovakia)

1978-04-01

Experience gained so far by the Department of Dermatovenerology in the uranium industry discloses that the incidence of occupational dermatoses is relatively low in this industry. It represents about 1% of all newly ascertained skin diseases per year. Allergic contact eczemas after having been in contact with rubber products, chiefly rubber boots, predominate. Under the working conditions in mining and preparing uranium ore, ionizing radiation cannot induce non-stochastic effects of the type of radiation dermatitis on the skin. A higher incidence was, however, ascertained in uranium miners of basaliomas, which agrees with the estimation of the dose of external alpha radiation in the basal epidermis layer.

In a prospective birth cohort study, we sought to identify perinatal predictors of the occurrence of atopic dermatitis in the first year of life. Associations of family history, infection during pregnancy, cord blood cytokine concentrations, and skin function parameters with atopic dermatitis were analyzed. Stratum corneum hydration was measured with an impedance meter until 5 days after delivery and again at 1 month. Complete data were obtained for 213 infants, including 27 diagnosed by a physician as having atopic dermatitis during their first year and 26 diagnosed as having infantile eczema during their first month. The risk of atopic dermatitis during the first year of life was related to maternal atopic dermatitis, lower concentrations of macrophage inflammatory protein-1beta in cord blood, and greater skin moisture in the surface and stratum corneum of the forehead and cheek at 1 month of age but not to viral or bacterial infection during pregnancy or breastfeeding. Paternal hay fever was associated negatively with the development of atopic dermatitis. High concentrations of interleukin-5, interleukin-17, and macrophage chemotactic protein-1 and only surface moisture in the cheek were associated with greater risk of infantile eczema in the first month. The association of atopic dermatitis in infancy with reduced neonatal macrophage inflammatory protein-1beta levels suggests a link with immature immune responses at birth. Stratum corneum barrier disruption in atopic dermatitis may involve impairment of cutaneous adaptation to extrauterine life. The majority of risk factors had different effects on infant eczema and atopic dermatitis, indicating different causes.

Preservative sensitivity patterns evolve with changing use patterns in products. During the last decade, the use of methylisothiazolinone (MI) at higher concentrations in both leave-on and rinse-off products has significantly increased. This is the first North American Contact Dermatitis Group reporting cycle that includes both methylchloroisothiazolinone (MCI)/MI and MI data. The aim of this study was to report the prevalence of isothiazolinone allergy (MCI/MI and MI) in the North American Contact Dermatitis Group patch-test population from January 1, 2013, to December 31, 2014. At 13 centers in North America, 4860 patients were patch tested in a standardized manner with a series of 70 allergens, including MCI/MI 0.01% aqueous (aq) and MI 0.2% aq. Three hundred five patients (6.3%) had a positive reaction to MCI/MI; this is a significant increase from the previous cycle (5.0%, 2011-2012; P = 0.011). Five hundred twenty-one patients (10.7%) had a positive reaction to MI. These 2 isothiazolinones were among the most common preservative allergens in the 2013 to 2014 cycle; 11.9% of patch-tested individuals were allergic to 1 or both isothiazolinones. Individuals with MCI/MI and MI allergy were significantly more likely to have occupationally related skin disease (P dermatitis (P < 0.0001, P = 0.0474). The epidemic of isothiazolinone sensitivity documented in Europe is now in North America. Patch testing with only MCI/MI 0.01% aq will miss approximately half of isothiazolinone allergy cases, whereas testing with only MI 0.2% aq will miss approximately 10% of isothiazolinone allergy cases.

Contact dermatitis to ethyl-cyanoacrylate-containing glue.

Science.gov (United States)

Belsito, D V

1987-10-01

3 patients with contact dermatitis to an ethyl cyanoacrylate glue are presented. Although reactions to cyanoacrylate glues are considered rare, more widespread use of these products by nail salons is likely to be associated with an increased incidence of positive reactions. All 3 of our patients came into contact with the glue during "nail wrapping". In this process, ethyl cyanoacrylate or another "instant glue" is used to adhere glue-impregnated silk or linen to the nail plate which is then filed to shape the nail. This procedure creates fine acrylic-containing dust which may facilitate an allergic response. Fine particulate matter may be transferred to other distant cutaneous sites, such as the eyelids, resulting in more widespread cutaneous eruptions. Dermatologists in areas where nail wrapping is becoming more fashionable are advised to be alert to potential cyanoacrylate glue allergies which present as periungual eczema which may be associated with eyelid dermatitis and features of nummular dermatitis particularly over the dorsal hand.

Kern, Malan; Shiver, Mallory B; Addis, Kristen M; Gardner, Jerad M

2017-09-01

Palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis are uncommon granulomatous dermatoses that often arise in association with rheumatoid arthritis. These 2 entities have overlapping features and may exist on a spectrum. We report an intriguing case of a 53-year-old man with advanced rheumatoid arthritis who presented with a large indurated painful truncal plaque with a palpable cord in addition to a papulonodular eruption on his dorsal hands. Furthermore, our patient had a recurrence in a near-identical mirror-image pattern on the contralateral trunk. The constellation of clinical and histopathological findings in our patient further suggests that palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis exist as overlapping disease entities on a continuum. In addition, we propose that recurrence of skin findings may be indicative of the severity of the underlying systemic disease process.

Full Text Available Actinic prurigo is a rare and acquired idiopathic photodermatosis. It usually shows childhood onset and female predominance. Here, we present an unusual case of a male patient with coexistence of adult-onset actinic prurigo and shampoo-induced allergic contact dermatitis. He was initially diagnosed with actinic prurigo. However, after detailed examination of the distribution of the rash, careful collection of his history, and interpretation of the results of histopathologic analysis, photo test, patch test, and photopatch test, coexistence of adult-onset actinic prurigo and shampoo-induced allergic contact dermatitis associated with cocamidopropyl betaine was diagnosed. The rash improved after appropriate use of sunscreen and avoidance of shampoo containing this allergen. Dermatologists should be aware of the possibility of concurrent photodermatitis and contact dermatitis.

Allergic contact dermatitis is a common skin disease, which affects approximately 20% of the population. This reaction may present with several clinical manifestations. Erythema multiforme-like allergic contact dermatitis is a rare type of non-eczematous contact dermatitis, which may lead to difficulty in diagnosis.Essential oil of Laurus nobilis is widely used in massage therapy for antiinflammatory and analgesic effects. Laurus nobilis induced contact dermatitis has been reported in the literature but an erythema multiforme-like presentation is rare.

Full Text Available The relationship between passive smoking and atopic dermatitis has previously been reported, but few studies have simultaneously evaluated the association of atopic dermatitis with active and passive smoking.The relationships between atopic dermatitis and active and passive smoking were evaluated in Korean adolescents. We used a large, representative, population-based survey (The Korea Youth Risk Behavior Web-based Survey conducted in 2011 and 2012. Active smoking was classified into 3 groups (0 days, 1-19 days, and ≥ 20 days/month. Passive smoking was categorized into 3 groups (0 days, 1-4 days, and ≥ 5 days/week. Atopic dermatitis diagnosed by a medical doctor either during the past 1 month or during the participant's lifetime was surveyed. Age, sex, obesity status, region of residence, economic level, and parental educational level of the participants were adjusted as confounders. Adjusted odds ratios (AORs and 95% confidence intervals (CI were calculated using multiple logistic regression analysis with complex sampling.A total of 6.8% (10,020/135,682 of the participants reported atopic dermatitis during the last 12 months. Active smoking was significantly associated with atopic dermatitis (previous 12 months (AOR [95% CI] of smoking ≥ 20 days/month = 1.18 [1.07-1.29]; 1-19 days/month = 1.11 [0.99-1.23], P = 0.002. Passive smoking was also related to atopic dermatitis (previous 12 months (AOR [95% CI] of smoking ≥ 5 days/week = 1.12 [1.05-1.20]; 1-4 days/week = 1.08 [1.03-1.13], P < 0.001.Atopic dermatitis was significantly associated with active and passive smoking in Korean adolescents.

Prevalence of occupational disease

Energy Technology Data Exchange (ETDEWEB)

Newhouse, M.L.

1976-12-01

When discussing the prevalence of occupational disease, both the prescribed diseases and the diseases where occupation has an important etiological component should be considered. Available statistics indicate that there has been a substantial improvement in the control of important prescribed diseases such as lead poisoning and pneumoconiosis. In the United Kingdom in 1900 there were 1000 cases of lead poisoning with 38 fatalities. This number decreased to 49 cases in 1956 when the number again increased due to a change from clinical diagnosis to diagnosis on biochemical evidence. The number of cases of coal workers' pneumoconiosis has declined since the 1950s but the number of coal miners has also been reduced by more than /sup 1///sub 3/. Industrial dermatitis is still a considerable problem. Vibration induced white fingers was mentioned as a disease with a very large occupational component but which for a variety of reasons is not prescribed for industrial injury benefit. Illnesses due to injuries to the back, to sciatica, disc disease or lumbago cause a very large amount of sickness and are often associated with heavy manual labor particularly if an awkward posture has to be adopted for the job. The average absence after a back injury in the London Docks was 61 days. Chronic bronchitis is the biggest single cause of sickness absence. Many studies have shown that the etiology is multifactorial but that hard physical work and a dusty environment in the work place are important adverse factors. Improved control of the working environment and methods of work may influence the development of chronic disease in the older worker.

Tacrolimus treatment of atopic eczema/dermatitis syndrome.

Science.gov (United States)

Thestrup-Pedersen, Kristian

2003-10-01

Atopic dermatitis is today the most common chronic disease of children in Europe, the US and Japan. The 'golden standard' of therapy is topical glucocorticosteroids and emollients. The steroids have been on the market for four decades, are efficacious, but only advised for short-term treatment due to their risks of side effects. More than 16,000 persons suffering from atopic dermatitis have been enrolled in clinical studies of tacrolimus. One third of patients with moderate to severe atopic dermatitis experience over 90% improvement in their disease over a 12-week treatment period and up to 70% of patients have over 50% improvement. A 1-year treatment leads to more than 90% improvement in 75% of patients. The most pronounced side effect is a burning sensation occurring in up to 60% of patients. Atopic dermatitis is a chronic skin disease leading to a demand for long-term treatment control. Such treatment options have not previously been available--except for emollients which are not efficacious for controlling skin inflammation. Tacrolimus and pimecrolimus are new treatment options, free from the potential side effects of topical steroids, which are known for their efficacy in short-term treatment. The new treatment modalities prevent the eczema from relapsing and at the same time they control active eczema. The future will see a shift towards the long-term use of tacrolimus which is able to control the skin inflammation and, hopefully, shorten the course of the eczema.

Literature review of the causes, treatment, and prevention of dermatitis linearis.

Science.gov (United States)

Beaulieu, Brooke A; Irish, Seth R

2016-04-01

Dermatitis linearis is a skin condition that affects both local populations and travelers alike. Dermatitis linearis is caused by some beetles within the subtribe Paederina and manifests as painful lesions, blisters and intense itching. Though outbreaks are widespread, the condition as a whole still remains relatively unknown. An extensive search of the existing Paederus literature was conducting in order to elucidate relevant information regarding the occurrence of outbreaks, seasonality, exposure and symptom onset, and management of dermatitis linearis. Special consideration was given to behavioral and environmental factors. Epidemics of dermatitis linearis are most commonly observed during the rainy season or after particularly hot and humid weather patterns. Symptom onset is typically delayed 6-48 h after exposure. The most common symptoms are stinging, burning and itching, with later development of erythematous plaques and blisters. Though symptoms of dermatitis linearis resolve spontaneously, wet compresses, antihistamines and topical steroid ointments and lotions are recommended to alleviate symptoms. Dermatitis linearis in travelers and local populations can be prevented through minimizing or modifying sources of artificial light, using pesticide-treated nets near beds and lights, general housekeeping and vegetation maintenance, and by raising awareness regarding the conditions caused by Paederus.

Full Text Available Background: A few reports demonstrate the comorbidity of food allergy and allergic march in adult patients. Aims and Objectives: To evaluate, if there is some relation in atopic dermatitis patients at the age 14 years and older who suffer from food allergy to common food allergens to other allergic diseases and parameters as bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. Materials and Methods: Complete dermatological and allergological examination was performed; these parameters were examined: food allergy (to wheat flour, cow milk, egg, peanuts and soy, the occurrence of bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. The statistical evaluation of the relations among individual parameters monitored was performed. Results: Food allergy was altogether confirmed in 65 patients (29% and these patients suffer significantly more often from bronchial asthma and allergic rhinitis. Persistent atopic dermatitis lesions and positive data in family history about atopy are recorded significantly more often in patients with confirmed food allergy to examined foods as well. On the other hand, the onset of atopic dermatitis under 5 year of age is not recorded significantly more often in patients suffering from allergy to examined foods. Conclusion: Atopic dermatitis patients suffering from food allergy suffer significantly more often from allergic rhinitis, bronchial asthma, persistent eczematous lesions and have positive data about atopy in their family history.

Information concerning health-related quality of life (HRQoL) and comorbidities of adult dermatitis patients stratified by loss-of-function mutations in the filaggrin gene (FLG) is limited. To investigate HRQoL, skin symptoms and comorbidities in adult FLG mutation carriers. This cross-sectional study included patients diagnosed with atopic dermatitis and/or hand eczema (n = 520). Patients completed questionnaires about dermatitis, skin symptoms, HRQoL, and comorbidities, including actinic keratosis, and atopic and mental disorders. FLG mutations (R501X, 2282del4, and R2447X) were identified in 16.9% of patients, and were significantly associated not only with atopic dermatitis, but also independently with skin fissures on the fingers and heels, and self-reported actinic keratosis. Although FLG mutations were significantly associated with reduced HRQoL, as measured by use of the Dermatology Life Quality Index (DLQI), no association with self-reported anxiety or depression was identified. Notably, the highest median DLQI score, reflecting greater impairment, was reported by patients with both FLG mutations and atopic dermatitis. Overall, 19.7% of patients with both atopic dermatitis and FLG mutations reported a 'large or extremely large' impact on their lives; this represents twice the prevalence seen in patients with atopic dermatitis and wild-type FLG (9.6%). Patients with both atopic dermatitis and common FLG mutations are more frequently affected by reduced HRQoL. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Acute radiation dermatitis remains one of the most commonly observed side effect during radiation therapy leading to complication such as superinfection or treatment disruption. Its management is characterized by a great heterogeneity. Few strategies have demonstrated a benefit in preventing radiation dermatitis, which relies mostly on decreasing dose delivered to the skin and skin care practices. Simple emollients and use of topical steroids can be useful in early stages. The singularity of the skin toxicity seen with cetuximab and radiotherapy warrants a specific grading system and distinctive clinical treatment with use of antibiotics. (authors)

Acute radiation dermatitis is a common side-effect of radiotherapy which often necessitates interruption of the therapy. Currently, there is no general consensus about its prevention or about the treatment of choice. The goal of this work was to focus on optimal methods to prevent and manage acute skin reactions related to radiation therapy and to determine if there are specific topical or oral agents for the prevention of this acute skin reaction. The prevention and the early treatment are the two focus points of the management of the acute radiation dermatitis. (authors)

Medical examination of the workers occupationally exposed to ionizing radiation

International Nuclear Information System (INIS)

Kato, Toshio

1991-01-01

The hazardous effects of ionizing radiation to man are well recognized, and they are divided into two groups, the stochastic effects (hereditary and carcinogenic effect) and non-stochastic effects (somatic effects such as depression of hematopoiesis, chronic dermatitis and cataracta). The basic framework of the International Commission on Radiological Protection (ICRP) is intended to prevent the occurrence of non-stochastic effects, by keeping doses below the relevant thresholds, and to ensure that all reasonable aspects are taken to reduce the incidence of stochastic effects. In Japan, the regulatory provisions of radiological protection of the workers occupationally exposed to ionizing radiation are based on the recommendation of ICRP adopted in 1977. According to these regulations, the dose equivalent limits of occupational exposure of man has been decided at 50 mSv/year. The monitoring of exposure to the individual and the procedure of medical examination of the workers are briefly described and discussed. (author)

Surgery-Related Contact Dermatitis: A Review of Potential Irritants and Allergens.

Science.gov (United States)

Cook, Kevin A; Kelso, John M

Surgical procedures utilize an increasing number of medical products including antiseptics, anesthetics, gloves, suture materials, tissue adhesives, topical antibiotics, and bandages. Many of these products have irritant potential. Allergic contact dermatitis has also been reported. This review covers preoperative, operative, and postoperative exposures that may result in contact dermatitis. Testing with standard patch panels such as T.R.U.E. Test and the North American Contact Dermatitis Group 65 allergen series does not evaluate for all relevant contactants. A thorough understanding of potential exposures is vital to effectively evaluate a patient with surgery-related contact dermatitis. A systematic approach is needed to ensure that standard patch panels and supplementary patches adequately address each encountered contactant.

[The role of the innate immune system in atopic dermatitis].

Science.gov (United States)

Volz, T; Kaesler, S; Skabytska, Y; Biedermann, T

2015-02-01

The mechanisms how the innate immune system detects microbes and mounts a rapid immune response have been more and more elucidated in the past years. Subsequently it has been shown that innate immunity also shapes adaptive immune responses and determines their quality that can be either inflammatory or tolerogenic. As atopic dermatitis is characterized by disturbances of innate and adaptive immune responses, colonization with pathogens and defects in skin barrier function, insight into mechanisms of innate immunity has helped to understand the vicious circle of ongoing skin inflammation seen in atopic dermatitis patients. Elucidating general mechanisms of the innate immune system and its functions in atopic dermatitis paves the way for developing new therapies. Especially the novel insights into the human microbiome and potential functional consequences make the innate immune system a very fundamental and promising target. As a result atopic dermatitis manifestations can be attenuated or even resolved. These currently developed strategies will be introduced in the current review.

Heo, Jin-Chul; Nam, Dong-Yoon; Seo, Myung Sun; Lee, Sang-Han

2011-11-01

To ascertain whether an aqueous fraction of Perilla frutescens Britton (PfB/af) has advantageous anti-atopic dermatitis activity, we used a 2,4-dinitrofluorobenzene (DNFB)-induced animal model of atopic dermatitis symptoms to investigate the effects of the extract. We performed an ear swelling assay by comparing thickness of the DNFB-induced ear, and measured the numbers of eosinophils as well as total immune cells. We analyzed the expression levels of matrix metalloproteinase (MMP)-9, interleukin (IL)-31 and of the T-bet transcription factor. The results revealed that PfB/af (100 µg/ml) exhibited strong anti-atopic dermatitis activity, interceding drastic reduction (35%) of the immune response, as measured by the thickness of ear epidermis swelling, and resulting in decreased eosinophil levels (73.7%) in adjacent skin tissues. Collectively, the present results suggest that PfB/af has potential for mitigation of atopic dermatitis-like symptoms induced by DNFB in the mouse.

Allergic contact dermatitis to quaternium 15 in a moisturizing lotion.

Cahill, Jennifer; Nixon, Rosemary

2005-11-01

A 56-year-old nurse from a rural area presented with a 12-month history of hand dermatitis. She had previously been patch tested by a local medical practitioner with the thin-layer rapid-use epicutaneous test, which had shown allergies to quaternium 15 and formaldehyde. After testing, she was prescribed methylprednisolone aceponate 1 mg/g cream by the medical practitioner, but was not informed that quaternium 15 is contained in the Microshield moisturizing lotion she was using at work. When her dermatitis persisted, she saw a dermatologist, who advised her to avoid the Microshield moisturizing lotion, and use a waterless hand cleanser on return to work. The diagnoses were firstly allergic contact dermatitis from quaternium 15 in the moisturizing lotion, and secondly irritant contact dermatitis from nursing work. This case highlights both the presence of quaternium 15 in a product commonly used in health-care settings in Australia, and the importance of offering informed, appropriate advice to patients following patch testing.

Satisfaction with treatment of atopic dermatitis in children

Directory of Open Access Journals (Sweden)

Małgorzata Maciejewska-Franczak

2016-05-01

Full Text Available Introduction . Atopic dermatitis is a frequent chronic skin disease in children. The major clinical manifestations include itching and dryness of the skin. The pathomechanism of skin changes results from an interaction of genetic and environmental factors as well as impairments of skin barrier function and immune response. Despite chronic treatment the disease is characterized by exacerbation and remission periods and lowers the quality of life of patients and their families. Objective. To evaluate treatment satisfaction in children with atopic dermatitis, identify components of medical care which contribute to treatment satisfaction, and evaluate the relationship between satisfaction and adherence to a doctor’s recommendations. Material and methods. One hundred and nineteen children (6 months to 12 years old, mean age 4.9 years with atopic dermatitis were enrolled in the study. The doctor performed physical examinations and history taking and filled in questionnaires evaluating the course and exacerbation of the disease, the type of administered therapy and diagnostics. The patients’ parents completed two questionnaires: a questionnaire assessing satisfaction with the therapy (the type of recommended therapy, adherence to recommendations, contact with the doctor, obtained information, degree of psychological support, role of parents in taking decisions regarding the therapy and a quality of life questionnaire. Results. The authors observed that 56% of parents were dissatisfied with the administered treatment, and 40% failed to adhere to at least one therapeutic recommendation. Parents of children with mild atopic dermatitis significantly more often stop using emollients. It was also observed that lack of treatment satisfaction in children with severe atopic dermatitis whose parents are insufficiently educated contributes to decreased adherence. The authors identified independent factors of lack of treatment satisfaction: failure to obtain

Evaluation of self-esteem and dermatological quality of life in adolescents with atopic dermatitis

2013-03-01

Full Text Available Background and Design: Atopic dermatitis is a chronic, inflammatory skin disease characterized by itchy skin lesions. Since adolescents are intensely interested in their physical appearance, chronic skin diseases in this period can adversely affect the development of self esteem. Atopic dermatitis is a skin disease that affects the appearance and there is an heightened attention to the body image in adolescence which is an important period of time in the development of self-esteem. Therefore, we aimed to investigate self-esteem and dermatological quality of life in adolescents with atopic dermatitis. Materials and Methods: Thirty-three patients with atopic dermatitis and 33 healthy controls were included in the study. The Piers-Harris Children’s Self-Concept Scale and the Children’s Dermatology Life Quality Index (CDLQI were used for determining self-esteem and quality of life. The Scoring of Atopic Dermatitis (SCORAD Index was used to assess the severity of atopic dermatitis. Results: It was found that patient group had lower self-esteem than healthy controls according to the Piers-Harris Children’s Self-Concept Scale. A statistically significant difference was observed in happiness/satisfaction and anxiety subscale scores between the patients and healthy controls while there was no significant difference between the other sub-scale scores. Mean value of dermatological quality of life in patients with atopic dermatitis was significantly lower than in healthy controls. A moderate negative correlation was found between self-esteem and CDLQI scores among adolescents with atopic dermatitis. Discussion: This study results have shown that self-esteem and dermatological quality of life were adversely affected in adolescents with atopic dermatitis irrespective of gender. These patients should be examined psychiatrically besides dermatological examination and treatment. We suggest that improvement will be observed in self-esteem and quality of

Prebiotics and probiotics: the prevention and reduction in severity of atopic dermatitis in children.

Science.gov (United States)

Foolad, N; Armstrong, A W

2014-06-01

The purpose of this review was to identify whether supplementation with prebiotics and/or probiotics help prevent the development or reduce the severity of atopic dermatitis in children less than three years of age. Since 1997, immunostimulatory supplements, such as prebiotics and probiotics, have been investigated. Various supplementations include probiotics (single strain or mix), probiotics with formula, probiotics mix with prebiotics, and prebiotics. In this narrative review, we examined 13 key articles on prebiotics and/or probiotics, and their effects on infant atopic dermatitis. Among the selected studies, a total of 3,023 participants received supplements or placebo. Eight out of the 13 (61.5%) studies reported a significant effect on the prevention of atopic dermatitis after supplementation with probiotics and/or prebiotics. Five out of the 13 (38.5%) studies indicated significant reduction in the severity of atopic dermatitis after supplementation. Based on the available studies, supplementation with certain probiotics (Lactobacillus rhamnosus GG) appears to be an effective approach for the prevention and reduction in severity of atopic dermatitis. A mix of specific probiotic strains prevented atopic dermatitis among infants. Based on studies with prebiotics, there was a long-term reduction in the incidence of atopic dermatitis. Supplementation with prebiotics and probiotics appears useful for the reduction in the severity of atopic dermatitis. Additional interventional studies exploring prebiotics and probiotics are imperative before recommendations can be made.

Hand dermatitis and symptoms from the fingers among Swedish dental personnel.

Lönnroth, E C; Shahnavaz, H

1998-01-01

Hand dermatitis among dental personnel has been an issue in recent years. Dental personnel manually handle polymer materials which are known to irritate skin, and also cause allergy. In addition, dental personnel wash their hands frequently, and use latex gloves, and are therefore at risk to develop hand dermatitis. To survey the occurrence of hand dermatitis among dental personnel, questionnaires were sent to all dental teams (dentist + chair assistant) working in the two northern Swedish counties. Referents were; researchers, teachers, and secretaries from a university and high schools, from the same geographical area. The response rate was 76% for dental teams, and 66% for referents. The results show that male dentists reported a significantly higher prevalence of hand dermatitis than male reference. In contrast to chair assistants and referents, dentists (both male and female) reported a higher extent of hand dermatitis on the left than on the right hand. There was an association between hand dermatitis among dental personnel and; age, eczema in childhood, and hay fever but, not with; sex, asthma, frequent washing of the hands, and glove use. Whitening of the fingers increased with increasing age among dental personnel. Pricking was also associated with frequent glove use. Pricking of the fingers was associated with sex, and 3.5 times more common among female dental personnel than male dentists. Numbness of the fingers, and finger pain was reported by more dentists than chair assistants and referents.

Atopic dermatitis (AD) and allergic contact dermatitis (ACD) have a dynamic relationship not yet fully understood. Investigation has been limited thus far by a paucity of data on the overlap of these disorders in pediatric patients. To use data from the Pediatric Contact Dermatitis Registry to elucidate the associations and sensitizations among patients with concomitant AD and ACD. This retrospective case review examined 1142 patch test cases of children younger than 18 years, who were registered between January 1, 2015, and December 31, 2015, by 84 health care providers (physicians, nurse practitioners, physician assistants) from across the United States. Data were gathered electronically from multidisciplinary providers within outpatient clinics throughout the United States on pediatric patients (ages 0-18 years). All participants were patch-tested to assess sensitizations to various allergens; history of AD was noted by the patch-testing providers. Primary outcomes were sensitization rates to various patch-tested allergens. A total of 1142 patients were evaluated: 189 boys (34.2%) and 363 girls (65.8%) in the AD group and 198 boys (36.1%) and 350 girls (63.9%) in the non-AD group (data on gender identification were missing for 17 patients). Compared with those without AD, patch-tested patients with AD were 1.3 years younger (10.5 vs 11.8 years; P dermatitis (3.5 vs 1.8 years; P < .001). Patch-tested patients designated as Asian or African American were more likely to have concurrent AD (odds ratio [OR], 1.92; 95% CI, 1.20-3.10; P = .008; and OR, 4.09; 95% CI, 2.70-6.20; P <.001, respectively). Patients with AD with generalized distribution were the most likely to be patch tested (OR, 4.68; 95% CI, 3.50-6.30; P < .001). Patients with AD had different reaction profiles than those without AD, with increased frequency of reactions to cocamidopropyl betaine, wool alcohol, lanolin, tixocortol pivalate, and parthenolide. Patients with AD were also noted

Children are as likely as adults to be sensitized and reactive to contact allergens. However, the prevailing data on pediatric allergic contact dermatitis are quantitatively and qualitatively limited because of a narrow geographic localization of data-reporting providers. The aim of the study was to present the first quarter results from the Loma Linda Pediatric Contact Dermatitis Registry focused on registered providers who self-identified as providing care for pediatric allergic contact dermatitis (ACD) within the United States. The US providers were invited to join the registry via completion of an online, secure, 11-question registration survey addressing demographics and clinical practice essentials. The presented results reflect data gathered within the first quarter of registry recruitment; registration is ongoing. Of 169 responders from 48 states, the majority of providers were female (60.4%), academic (55.6%), and dermatologists (76.3%). Based on individual provider averages, the minimum cumulative number of pediatric patch-test evaluations performed each year ranged between 1372 and 3468 children. The Pediatric Contact Dermatitis Registry provides a description of the current leaders in the realm of pediatric ACD and gaps, which are in need of attention. The registry allows for a collaborative effort to exchange information, educate providers, and foster investigative research with the hope of legislation that can reduce the disease burden of ACD in US children.

Occupational contact urticaria (OCU) is an occupational contact dermatitis that can cause serious health consequences and disability at work. To describe OCU and its temporal trends by the main causal agents and activity sectors in a nationwide scheme in France. Using data from the French National Network for Occupational Disease Vigilance and Prevention (RNV3P), we described OCU reported during the period 2001-10 and analysed the temporal trends of OCU and OCU attributed to the most frequent agents over the study period. Trends analyses were supported by reporting odds ratios using a logistic regression model with reference to 2001, or with time as a continuous variable. During the study period, 251 cases of OCU were reported in RNV3P, half of which were due to natural rubber latex, in particular in the health and social work activity sector (HSW). The number of these cases declined significantly over the study period (19% per year), and particularly after 2006. Conversely, the other causes of OCU did not decrease. Using surveillance data from a French national network, this study has found that there was a significant decline in OCU due to natural rubber latex, particularly in the HSW, when powdered latex gloves were banned from French hospitals. Our results show the effectiveness of this preventive measure, and suggest that this practice should be extended to other sectors. © 2015 British Association of Dermatologists.

Atopic dermatitis is a chronic inflammatory skin disease. The objective of this study was to characterize the burden of atopic dermatitis in Japanese adult patients relative to the general population. Japanese adults (≥18 years) with a self-reported diagnosis of atopic dermatitis and adult controls without atopic dermatitis/eczema/dermatitis were identified from the 2013 Japan National Health and Wellness Survey. Atopic dermatitis patients were propensity-score matched with non-atopic dermatitis controls (1:2 ratio) on demographic variables. Patient-reported outcome data on comorbidities, mood and sleep disorders, health-related quality of life, work productivity and activity impairment, and health-care resource utilization were analyzed in atopic dermatitis patients and matched controls. A total of 638 Japanese adult patients with atopic dermatitis were identified, of whom 290 (45.5%) rated their disease as "moderate/severe" and 348 (54.5%) as "mild". The analysis cohort comprised 634 atopic dermatitis patients and 1268 matched controls. Atopic dermatitis patients reported a significantly higher prevalence of arthritis, asthma, nasal allergies/hay fever, anxiety, depression and sleep disorders compared with controls (all P Atopic dermatitis patients also reported a significantly poorer health-related quality of life, higher overall work and activity impairment, and higher health-care resource utilization (all P atopic dermatitis reported a substantial disease burden relative to adults without atopic dermatitis, suggesting an unmet need for effective strategies targeting disease management. © 2018 The Authors.

2013-05-01

The effects of scalp dermatitis (seborrheic dermatitis (SD), psoriasis, and atopic dermatitis (AD)) on chemical properties of hair keratin were investigated by Fourier transform infrared (FT-IR) spectroscopy. Hairs were collected from lesional regions affected by SD, psoriasis, and AD and non-lesional regions separately. The hairs with SD were taken from patients with ages of 16-80 years. The ages of patients with psoriasis ranged from 8 to 67 years, and all patients exhibited moderate disease. Hairs with AD were taken from the patients with ages of 24-45 years and the average SCORing atopic dermatitis (SCORAD) was 48.75. Hairs from 20 normal adults were collected as a control. The FT-IR absorbance bands were analyzed by the Gaussian model to obtain the center frequency, half width, height, and area of each band. The height and area of all bands in the spectra were normalized to the amide I centered at 1652 cm-1 to quantitatively analyze the chemical composition of keratin. The spectra of hair with scalp dermatitis were different with that of control, the amide A components centered at 3278 cm-1 were smaller than those of the control. The psoriasis hair showed a large difference in the IR absorbance band between lesional and non-lesional hairs indicating good agreement with the morphological changes. The hairs with diseases did not show differences in the content of cystine, which was centered at 1054 cm-1, from the control. The chemical properties of keratin were not significantly different between the hairs affected by SD, psoriasis, and AD. However, the changes induced by scalp dermatitis were different with weathering. Therefore, FT-IR analysis could be used to screen differences between the physiological and pathological conditions of scalp hair.

Full Text Available In dogs, dermatitis due to mixed mite infestation is rare. During the five-year period of study, two dogs were identified suffering from dermatitis due to mixed Demodex and Sarcoptes mites. Upon clinical examination dogs had primary and secondary skin lesions on face, around the ears, chin, neck, fore limbs and lateral abdomen. Microscopic examination of skin scrapings revealed Demodex and Sarcoptes mites. Both dogs were treated with daily oral ivermectin at 100 to 400 μg/kg body weight as incremental doses, external application of amitraz and supportive treatments with topical antimicrobial shampoo. After completion of forty-two days of therapy, dogs were recovered from the dermatitis.

Full Text Available A 50-year-old mining engineer at Dhanbad was having air bome contact Dermatitis suspected to be caused by Xanthium strumarium. Patch tests with a 15% aqueous extract of air dried leaves showed a severe positive reaction, but the patient also had positive patch tests with Parthenium hysterphorus and a few other weeds and trees known to cause air-borne contact dermatitis. The titre of contact hypersensitivity with the extract of Xanthium struma′rium was more than 1:100,000 and for Parthenium hysterophrous it was 1:10 indicating a high degree of hypersensitivity to Xanthium strumarium. Further tests in 14 other patients revealed a high prevalence of cross sensitivity between these two plants both of which belong to the compositae family.

Allergic contact dermatitis (ACD), a common dermatological disorder, often results in ongoing disease and disability. However, relatively little has been published quantifying the quality of life (QoL) of patients with ACD. This study was conducted to investigate the impact of ACD on QoL and explore prognostic factors that influence outcomes. A total of 428 subjects with ACD were, at varying times after diagnosis, mailed a QoL questionnaire modified from Skindex-16 to include an additional 5 items pertaining to occupational impact. The QoL scores were correlated with subject demographics, disease characteristics, and management techniques to ascertain factors that impact QoL in subjects with ACD. The response rate was 35%, with 149 subjects returning the postal survey. Responders reported being bothered most by itching, skin irritation, and persistence of the condition. Of the four scales included in the QoL questionnaire, the emotions scale had the worst composite QoL score, followed by symptoms, functioning, and occupational impact. Patients with ACD of the face were significantly more bothered by the appearance of their skin. Hand involvement and occupationally related ACD were associated with worse QoL scores within the occupational impact and functioning scales. Subjects that had changed jobs because of ACD had more severe QoL impairment than any other group analyzed, with significantly worse scores on 17 of the 21 QoL items. A history of atopic eczema seemed to impart improved outcomes on patients with ACD, and these subjects were less worried about being fired from their jobs. Subjects diagnosed by patch testing more than 36 months after disease onset seemed to have worse QoL scores than those diagnosed earlier in the natural history of the disease. Patients diagnosed by patch testing within the last 6 months had the worst QoL scores, while the best outcomes were reported in subjects patch tested 6 to 12 months ago. A slight decline in QoL was observed 12

We investigated the frequency, degree and risk factors of radiation-induced dermatitis and pneumonitis in 255 patients receiving breast conserving therapy between April 1987 and April 1998. The majority of the patients underwent a wide excision or quadrantectomy with a level I, II axillary dissection, followed by radiotherapy consisting of 50 Gy/25 Fr/5 weeks to the preserved breast with a 4 MV beam by tangentially opposed portals using the half-field technique. Eleven patients received an additional 10 Gy/5 Fr of electron therapy to the tumor bed. Most of the patients developed radiation dermatitis which was limited to reddening or dry desquamation, with the exception of 14 patients with a localized moist reaction. The skin reaction was transient in all patients and improved with conservative treatments. Radiation pneumonitis appeared on chest X-rays in 30 patients, with a slight appearance in 21 and patchy appearance in 9. Three patients presented with persistent symptoms requiring medication. They were treated with steroids, resulting in complete resolution of the symptoms. A large volume of the chest wall within the irradiation field and a large area of irradiated skin were the risk factors of radiation dermatitis. The volume of irradiated lung significantly correlated with the frequency and degree of radiation pneumonitis. It was preferable that the maximum thickness of the involved lung should not exceed 3 cm. Complicated disease, adjuvant therapy and boost irradiation had no impact on the radiation dermatitis or pneumonitis. (author)

Live bee acupuncture (Bong-Chim) dermatitis: dermatitis due to live bee acupuncture therapy in Korea.

2013-12-01

Live bee acupuncture (Bong-Chim) dermatitis is an iatrogenic disease induced by so-called live bee acupuncture therapy, which applies the honeybee (Apis cerana) stinger directly into the lesion to treat various diseases in Korea. We present two cases of live bee acupuncture dermatitis and review previously published articles about this disease. We classify this entity into three stages: acute, subacute, and chronic. The acute stage is an inflammatory reaction, such as anaphylaxis or urticaria. In the chronic stage, a foreign body granuloma may develop from the remaining stingers, similar to that of a bee sting reaction. However, in the subacute stage, unlike bee stings, we see the characteristic histological "flame" figures resulting from eosinophilic stimulation induced by excessive bee venom exposure. We consider this stage to be different from the adverse skin reaction of accidental bee sting. © 2013 The International Society of Dermatology.

Full Text Available Introduction: Systemic contact dermatitis (SCD is a systemic reactivation of a previous allergic contact dermatitis. The initial exposure may usually be topical, followed by oral, intravenous or inhalation exposure leading to a systemic hypersensitivity reaction. A case of a 27 year-old male with SCD due to nickel is reported Case Report: A 27 year-old male presented with recurrent pruritic eruption consist of deep seated vesicles on both palmar and left plantar since 6 months before admission. This complaint began after patient consumed excessive amounts of chocolate, canned food, and beans. The patient worked as a technician in a food factory. History of allergy due to nickel was acknowledged since childhood. The clinical presentation was diffuse deep seated vesicles, and multiple erythematous macules to plaques, with collarette scale. Patch test using the European standard showed a +3 result to nickel. The patient was diagnosed as systemic contact dermatitis due to nickel. The treatments were topical corticosteroid and patient education of avoidance of both contact and systemic exposure to nickel. The patient showed clinical improvement after 2 weeks. Discussion: SCD was diagnosed due to the history of massive consumption of food containing nickel in a patient who had initial sensitization to nickel, with clinical features and the patch test result. Advice to be aware of nickel and its avoidance is important in SCD management.

Coin exposure may cause allergic nickel dermatitis: a review.

Thyssen, Jacob P; Gawkrodger, David J; White, Ian R; Julander, Anneli; Menné, Torkil; Lidén, Carola

2013-01-01

Nickel is used in coins because the metal has beneficial properties, including price, colour, weight, and corrosion resistance, and also because it is easy to stamp. It has often been claimed that the duration of skin contact with coins is too short to cause nickel release and dermatitis. However, it is well known by dermatologists specialized in occupational skin diseases, and by their nickel-allergic patients, that hand eczema in cashiers and other professionals who handle coins may be caused or aggravated by nickel release from coins. In this review, we present evidence from past studies showing that nickel-containing coins can indeed pose a risk for those who handle them. For protection of the health of consumers, cashiers, and other workers who handle coins, it is suggested that coins without nickel release should be used as a substitute for the high nickel-releasing coins currently in widespread use. The key risk factor in this situation is the ability of metal alloys in coins to release nickel and contaminate the skin after repeated contact from coin handling. © 2012 John Wiley & Sons A/S.

Atopic dermatitis is a complex disease of heterogeneous pathogenesis, in particular, genetic predisposition, environmental triggers, and their interactions. Indoor air pollution, increasing with urbanization, plays a role as environmental risk factor in the development of AD. However, we still lack a detailed picture of the role of air pollution in the development of the disease. Here, we examined the effect of formaldehyde (FA) exposure on the manifestation of atopic dermatitis and the underlying molecular mechanism in naive rats and in a rat model of atopic dermatitis (AD) produced by neonatal capsaicin treatment. The AD and naive rats were exposed to 0.8 ppm FA, 1.2 ppm FA, or fresh air (Air) for 6 weeks (2 hours/day and 5 days/week). So, six groups, namely the 1.2 FA-AD, 0.8 FA-AD, Air-AD, 1.2 FA-naive, 0.8 FA-naive and Air-naive groups, were established. Pruritus and dermatitis, two major symptoms of atopic dermatitis, were evaluated every week for 6 weeks. After that, samples of the blood, the skin and the thymus were collected from the 1.2 FA-AD, the Air-AD, the 1.2 FA-naive and the Air-naive groups. Serum IgE levels were quantified with ELISA, and mRNA expression levels of inflammatory cytokines from extracts of the skin and the thymus were calculated with qRT-PCR. The dermatitis and pruritus significantly worsened in 1.2 FA-AD group, but not in 0.8 FA-AD, compared to the Air-AD animals, whereas FA didn't induce any symptoms in naive rats. Consistently, the levels of serum IgE were significantly higher in 1.2 FA-AD than in air-AD, however, there was no significant difference following FA exposure in naive animals. In the skin, mRNA expression levels of Th1 cytokines such as TNF-α and IL-1β were significantly higher in the 1.2 FA-AD rats compared to the air-AD rats, whereas mRNA expression levels of Th2 cytokines (IL-4, IL-5, IL-13), IL-17A and TSLP were significantly higher in 1.2 FA-naive group than in the Air-naive group.

Occupational dermatoses from colophony exposure

Directory of Open Access Journals (Sweden)

Aleš Christian Mihelač

2015-04-01

Full Text Available Colophony is a resin, obtained from pine trees. It has many applications in industry as well as in products for everyday life and exposure is virtually impossible to avoid. In article, we concentrate on occupational exposure, which is frequent in workers in electronics, furniture and paper industry, production of adhesives, plastics, printing ink and synthetic rubber as well as in everyone, daily in contact with products, which contain colophony, or pine wood, like carpenters and woodworkers. Main allergens are oxidation products of abietic-type acids, but cross-reactivity with fragrances, wood resins, Balsam of Peru, wood tar and oil of turpentine is also possible. Exposure to colophony manifests itself on skin in allergic patients mainly as allergic contact dermatitis. The diagnosis is based on history of exposure, clinical presentation and epicutaneous testing. Although the only effective treatment is complete avoidance of exposure, it is difficult to avoid colophony. Consequently, prophylaxis is essential and concentrates on safe working practices, personal hygiene and protection.

Active sensitization to paraphenylendiamine (PPD) and related compounds from temporary black henna tattoos has become an epidemic in the recent years. Hair dyes also include PPD like black henna tatoos which cause allergic contact dermatitis. Skin lesions of allergic contact dermatitis from PPD are mostly seen as an exudative erythema, an erythema multiforme-like eruption or a bullous contact dermatitis. We, herein, report a 27 year-old woman with an angioedema-like reaction occurring after the first exposure to hair dye who was unaware of being previously sensitized to PPD from black henna tattoo.

Patch testing is an important diagnostic tool for assessment of allergic contact dermatitis (ACD). This study documents the North American Contact Dermatitis Group (NACDG) patch-testing results from January 1, 2011, to December 31, 2012. At 12 centers in North America, patients were tested in a standardized manner with a series of 70 allergens. Data were manually verified and entered into a central database. Descriptive frequencies were calculated, and trends analyzed using χ statistics. Four thousand two hundred thirty-eight patients were tested; of these, 2705 patients (63.8%) had at least 1 positive reaction, and 2029 (48.0%) were ultimately determined to have a primary diagnosis of ACD. Four hundred eight patients (9.6%) had occupationally related skin disease. There were 7532 positive allergic reactions. As compared with previous reporting periods (2009-2010 and 2000-2010), positive reaction rates statistically increased for 6 allergens: methylchloroisothiazolinone/methylisothiazolinone (5.0%; risk ratios [RRs]: 2.01 [1.60-2.52], 1.87 [1.61-2.18]), lanolin alcohol (4.6%; RRs 1.83 [1.45-2.30], 2.10 [1.79-2.47]), cinnamic aldehyde (3.9%; 1.69 [1.32-2.15], 1.53 [1.28-1.82]), glutaral (1.5%; 1.67 [1.13-2.48], 1.31 [1.00-1.71]), paraben mix (1.4%; 1.77 [1.16-2.69], 1.44 [1.09-1.92]), and fragrance mix I (12.1%; RRs 1.42 [1.25-1.61], 1.24 [1.14-1.36]). Compared with the previous decade, positivity rates for all formaldehyde-releasing preservatives significantly decreased (formaldehyde 6.6%; RR, 0.82 [0.73, 0.93]; quaternium-15 6.4% RR 0.75 [0.66, 0.85]; diazolidinyl urea 2.1%; RR, 0.67 [0.54, 0.84]; imidazolidinyl urea 1.6%, 0.60 [0.47, 0.77]; bronopol 1.6%; RR, 0.60 [0.46, 0.77]; DMDM hydantoin 1.6%; RR, 0.59 [0.54, 0.84]). Approximately a quarter of patients had at least 1 relevant allergic reaction to a non-NACDG allergen. In addition, approximately one-fourth to one-third of reactions detected by NACDG allergens would have been hypothetically missed by T

Preservatives are biocidal chemicals added to food, cosmetics, and industrial products to prevent the growth of microorganisms. They are usually nontoxic and inexpensive and have a long shelf life. Unfortunately, they commonly cause contact dermatitis. This article reviews the most important classes of preservatives physicians are most likely to encounter in their daily practice, specifically isothiazolinones, formaldehyde and formaldehyde-releasers, iodopropynyl butylcarbamate, methyldibromoglutaronitrile, and parabens. For each preservative mentioned, the prevalence of sensitization, clinical presentation of contact dermatitis, patch testing concentrations, cross reactions, and related legislation will be discussed. Mandatory labeling of preservatives is required in some countries, but not required in others. Until policies are made, physicians and patients must be proactive in identifying potential sensitizers and removing their use. We hope that this article will serve as a guide for policy makers in creating legislation and future regulations on the use and concentration of certain preservatives in cosmetics and industrial products.

Corticosteroid therapy in the treatment of pediatric patients with atopic dermatitis

Full Text Available Health political background: In developed countries 2.5% of the population - mainly children - are affected by atopic dermatitis. During the past few years its prevalence amongst school children has risen decisively and now lies between 8% to 16%. It is the most frequent chronic skin disease amongst school-aged children. Scientific background: Current methods of treating atopic dermatitis among children focus on containing and preventing the illness’s further progression. Preventing dry skin, relieving symptoms (such as pruritis and inflammation of the skin and identifying and avoiding provocating factors are elementary goals of treatment. Successful treatment can substantially increase the children’s quality of life. Possible therapies of children affected by atopic dermatitis include both topically and systemically applied pharmaceuticals. During the past ten years the use of corticosteroids has been the standard topical anti-inflammatory therapy in case of aggravating inflammations. In 2002 a new group of pharmaceutical substances (topical calcineurin inhibitors tacrolimus and pimecrolimus was authorised in Germany for topical anti-inflammatory treatment of patients. Because of its high prevalence atopic dermatitis represents a major expense factor to the German health care system. In 1999 the costs of the treatment of atopic dermatitis with corticosteroids in Germany amounted to 230 million Euro. If other direct costs for the treatment are included, for example hospitalisation or doctor appointments, the total costs amount to 3.57 billion Euro. Research question: How effective and efficient are topical anti-inflammatory treatments of children with atopic dermatitis? Methods: A systematic literature search was performed in 35 international databases which yielded 1335 articles. Following a two-part selection process according to predefined criteria 24 publications were included in the assessment. Results: Of 19 randomised controlled

Periocular contact dermatitis may appear as contact conjunctivitis, contact allergic and/or irritative eyelid and periorbital dermatitis, or a combination of these symptoms. The clinical symptoms may be induced by several environmental and therapeutic contact allergens. The aim of the present study was to map the eliciting contact allergens in 401 patients with periocular dermatitis (PD) by patch testing with environmental and ophthalmic contact allergens. Following the methodics of international requirements, 401 patients were tested with contact allergens of the standard environmental series, 133 of 401 patients with the Brial ophthalmic basic and supplementary series as well. Contact hypersensitivity was detected in 34.4% of the patients. Highest prevalence was seen in cases of PD without other symptoms (51.18%), in patients of PD associated with ophthalmic complaints (OC; 30.4%), and PD associated with atopic dermatitis (AD; 27.9%). In the subgroup of PD associated with seborrhoea (S) and rosacea (R), contact hypersensitivity was confirmed in 17.6%. Most frequent sensitisers were nickel sulphate (in 8.9% of the tested 401 patients), fragrance mix I (4.5%), balsam of Peru (4.0%), paraphenylendiamine (PPD) (3.7%), and thiomersal (3.5%). By testing ophthalmic allergens, contact hypersensitivity was observed in nine patients (6.7% of the tested 133 patients). The most common confirmed ophthalmic allergens were cocamidopropyl betaine, idoxuridine, phenylephrine hydrochloride, Na chromoglycinate, and papaine. Patients with symptoms of PD were tested from 1996 to 2006. The occurence of contact hypersensitivity in PD patients was in present study 34.4%. A relatively high occurrence was seen in cases of PD without other symptoms, in PD + OC and in PD + AD patients. The predominance of environmental contact allergens was remarkable: most frequent sensitizers were nickel sulphate, fragrance mix I, balsam of Peru, thiomersal, and PPD. The prevalence of contact

Full Text Available Background. Research has confirmed the involvement of oxidative stress (OxS in allergic contact dermatitis whilst other inflammation-related biomarkers have been less studied. Objective. To evaluate systemic levels of selected inflammatory markers, OxS indices and adipokines as well as their associations in allergic contact dermatitis. Methods. In 40 patients, interleukin- (IL- 6, monocyte chemoattractant protein (MCP-1, and IL-10 levels were measured in sera with the Evidence Investigator Cytokine & Growth factors High-Sensitivity Array, total peroxide concentration (TPX and total antioxidant capacity (TAC by means of spectrophotometry, and the plasma concentrations of adiponectin and leptin by the quantitative sandwich enzyme immunoassay technique. Results. TNF-α level (P < 0.01 and TPX (P < 0.0001 were increased whilst IL-10 (P < 0.05 and TAC (P < 0.0001 were decreased in the patients as compared to controls. Correlation and multiple linear regression analysis identified both, TPX and TAC (inversely, as possible independent markers for evaluating allergic contact dermatitis. Adiponectin level in patients was increased (P < 0.0001, but neither adiponectin nor leptin correlated significantly with the biomarkers of inflammation or OxS. Conclusion. OxS parameters, especially TPX and OSI, reflect the degree of systemic inflammation associated with allergic contact dermatitis in the best way. The relation between OxS and adiponectin level warrants further studies.

Contact dermatitis is a frequent inflammatory skin disease. A suspected diagnosis is based on clinical symptoms, a plausible contact to allergens and a suitable history of dermatitis. Therefore, careful diagnosis by patch testing is of great importance because the patch testing is important to find out which allergen/material causes the complaints. Metallic allergens such as cobalt are among the most common causes of allergic contact dermatitis, but frequencies of contact dermatitis to these allergens may vary in different skin areas. Here, we report an unusual case of cobalt allergy on the skin contact with the prosthetic leg of a 30-year-old female patient. The patient developed maculopapular and vesicular lesions on her contact region of residual limb to prosthetic leg. She underwent standard patch testing, which resulted in a strong positive reaction to cobalt chloride. This case report may serve to remind doctors to be aware of potential allergic reactions to prostheses and to enable them to recognize a metal allergy if it appears. Prosthetists should also be reminded of potential allergic reactions. Cobalt can be used as an accelerator in making a prosthetic socket. Several cases have been reported concerning allergies to components of the prosthetic socket. This is the first report of sensitization to cobalt which is used in making a prosthetic leg. © The International Society for Prosthetics and Orthotics 2014.

2002-05-01

Three varieties of a popular African cichlid aquarium species, Pseudotropheus zebra, from 2 tropical fish farms in east central Florida were submitted for diagnostic evaluation because of the development of multifocal green lesions. The percentage of infected fish in these populations varied from 5 to 60%. Fish were otherwise clinically normal. Microscopic examination of fresh and fixed lesions confirmed algal dermatitis, with light invasion of several internal organs in each group. A different alga was identified from each farm. Fish from farm A were infected with Chlorochytrium spp, whereas fish from farm B were infected with Scenedesmus spp. Because of the numbers of fish involved, bath treatments to remove the algae from affected fish from farm B were attempted, with different dosages of several common algaecides including copper sulfate pentahydrate, diuron, and sodium chloride. However, none of these treatments were successful, possibly because of the location of the algae under the scales and within the dermis, and also because of the sequestering effect of the granulomatous response. To our knowledge, this is the first report of algal dermatitis in ornamental cichlids, as well as the first report of Scenedesmus spp infection in any fish.

Allergic diseases, including asthma, allergic rhinitis, atopic dermatitis, food allergy, and urticaria are common in general pediatric practice. This review highlights several significant advances in pediatric allergy over the past year, focusing on asthma and atopic dermatitis. With increasing options for the treatment of allergic diseases, much work is now focused on methods for individualizing treatments to a patient's phenotype and genotype. Progress over the past year includes the characterization of effects of regular albuterol use in patients with genetic variations in the beta-adrenergic receptor. Maintenance asthma regimens for children in the first years of life are also an ongoing focus. The relation between upper airway allergic inflammation and asthma has continued to accumulate support and now extends to the middle ear. Environmental influences on asthma and interventions have been described, including environmental controls for asthma and the role of air pollution on lung development in children. Finally, concerns have been raised regarding the use of topical immunomodulators in young children with atopic dermatitis. Progress continues in the care of children with atopic diseases. Attention to treatment with appropriate medications, patient-individualized environmental controls, and extensive education are the keys to successfully treating atopic children. This review highlights several recent advances but is not intended to be a comprehensive review.

Contact dermatitis is a common skin disease. Disease was diagnosed by a history of contact substance together with geographic distribution of lesion. Up till now, standard patch test is one of the most reliable test to identify and confirm causative agent of allergic contact dermatitis. To determine the rate of positive standard patch test and to identify the common allergen of contact dermatitis in Thailand, we performed the standard patch test in 129 patients, suspected having allergic contact dermatitis at Department of Dermatology, King Chulalongkorn Memorial Hospital, Thailand from June 1, 2003 to September 1, 2004. The rate of positive standard patch test is 59.7% (n = 77/129). The most 3 common positive allergens were nickel sulfate (18.60%), cobalt chloride (17.05%) and fragrance mix (14.73%), respectively. The chance of positive standard patch test significantly correlated with sex (woman), initial diagnosis as contact dermatitis and history of house-worker (p = 0.017, p = 0.005 and p = 0.023, respectively). Whereas, there were no significant correlation between the chance of positive standard patch test and age of patient, location of lesion, history of recurrence, history of atopy, history of drug and food allergy. In addition, history of metal allergy significantly correlated with the chance of positive nickel sulfate or cobalt chloride in standard patch test (p = 0.017). In conclusion, this study demonstrated the prevalence of causative allergen of contact dermatitis in Thai patients using that standard patch test. Moreover, our data shown that the chance positive standard patch test was greater in patient, who were women or initial diagnosed as contact dermatitis or had history of houseworker or history of metal allergy.

Dimethyl fumarate (DMF) is an effective inhibitor of mold growth. In very low concentrations, DMF is a potent sensitizer that can cause severe allergic contact dermatitis (ACD). It has been identified as the agent responsible for furniture contact dermatitis in Europe. The aim of this study was to evaluate patients in Slovakia with footwear ACD associated with DMF, with regard to clinical manifestations, patch test results, and results of chemical analysis of their footwear. Nine patients with suspected footwear contact dermatitis underwent patch testing with the following allergens: samples of their own footwear, commercial DMF, the European baseline, shoe screening, textile and leather dye screening, and industrial biocides series. The results were recorded according to international guidelines. The content of DMF in footwear and anti-mold sachets was analyzed using gas chromatography and mass spectrometry. Acute ACD was observed in nine Caucasian female patients. All patients developed delayed sensitization, as demonstrated by positive patch testing using textile footwear lining. Seven patients were patch tested with 0.1% DMF, and all seven were positive. Chemical analysis of available footwear showed that DMF was present in very high concentrations (25-80 mg/Kg). Dimethyl fumarate is a new footwear allergen and was responsible for severe ACD in our patients. To avoid an increase in the number of cases, the already approved European preventive measures should be accepted and commonly employed. © 2013 The International Society of Dermatology.

Atopic dermatitis is a chronically relapsing, highly pruritic and inflammatory skin disease. This study was done to assess the effects of vitamins D and E supplementation on the clinical manifestation of atopic dermatitis. Forty-five atopic dermatitis patients were included in a randomized, double-blind, placebo-controlled trial. They were randomly divided into four groups and treated for 60 days: group P (n = 11), vitamins D and E placebos; group D (n = 12), 1600 IU vitamin D(3) plus vitamin E placebo; group E (n = 11), 600 IU synthetic all-rac-α-tocopherol plus vitamin D placebo; and group DE (n = 11), 1600 IU vitamin D(3) plus 600 IU synthetic all-rac-α-tocopherol. Serum 25(OH) vitamin D and plasma α-tocopherol were determined before and after the trial. The clinical improvement was evaluated with SCORing Atopic Dermatitis (SCORAD). Data were analyzed by analysis of variance (ANOVA) and Kruskal-Wallis tests. SCORAD was reduced after 60 days in groups D, E and DE by 34.8%, 35.7% and 64.3%, respectively (p = 0.004). Objective SCORAD also showed significant improvement. There was a positive correlation between SCORAD and intensity, objective, subjective and extent (p vitamins D and E in the treatment of atopic dermatitis.

Occupational exposure of hairdressers to hair dyes has been associated with the development of allergic contact dermatitis (ACD) involving the hands. p-Phenylenediamine (PPD) and toluene-2,5-diamine (PTD) have been implicated as important occupational contact allergens. To conduct a quantitative risk assessment for the induction of contact sensitization to hair dyes in hairdressers, available data from hand rinsing studies following typical occupational exposure conditions to PPD, PTD and resorcinol were assessed. By accounting for wet work, uneven exposure and inter-individual variability for professionals, daily hand exposure concentrations were derived. Secondly, daily hand exposure was compared with the sensitization induction potency of the individual hair dye defined as the No Expected Sensitization Induction Levels (NESIL). For PPD and PTD hairdresser hand exposure levels were 2.7 and 5.9 fold below the individual NESIL. In contrast, hand exposure to resorcinol was 50 fold below the NESIL. Correspondingly, the risk assessment for PPD and PTD indicates that contact sensitization may occur, when skin protection and skin care are not rigorously applied. We conclude that awareness of health risks associated with occupational exposure to hair dyes, and of the importance of adequate protective measures, should be emphasized more fully during hairdresser education and training.

Many patients with atopic dermatitis showed immediate-type hypersensitivity against sweat antigen. Therefore, to deal with sweating is important to prevent itching and aggravations of dermatitis of patient with atopic dermatitis. We had searched a substance that inactivated sweat antigen adopting histamine release test. And we found that tannic acid which selected by screening various natural products inactivated sweat antigen. We evaluate skin care products (spray, after-bathing water and aerosol-spray) containing tannic acid for patients with atopic dermatitis. We administered in a tannic acid-containing spray and after-bathing water on 17 patients with atopic dermatitis. After treatment, total clinical assessment score and itching in the afternoon had significantly decreased from that on day 0. To evaluate the effect of tannic acid containing-aerosol spray on itching of patients with AD, we assessed symptoms of atopic dermatitis patients who used a tannic acid containing-aerosol spray every day for 4 weeks in a cross-over, double-blind study. Clinical severity of atopic dermatitis and degrees of itching in daily life of patients were evaluated by physicians and patients themselves, respectively. Degrees of itching in morning and those at night were significantly more largely improved by the use of tannic acid-containing aerosol spray than those by the use of placebo control aerosol spray. The overall efficacy of tannic acid-containing aerosol sprays was also significantly higher than those of tannic acid free spray. Sweat antigen inactivating skin care products may be effective to reduce itching of patients with atopic dermatitis.

The objective of this report is to describe workers' job-related diseases and the occupations associated with those diseases. The methods include aggregation and analysis of job-related disease and occupation data from the Bureau of Labor Statistics' Supplementary Data System (SDS) for 1985 and 1986--the last years of data available with workers' compensation categories: death, permanent total, permanent partial, and temporary total and partial. Diseases are ranked according to their contribution to the four workers' compensation (WC) categories and also ranked within occupations according to the number of cases. Occupations are ranked according to their contribution to specific diseases within one of the four categories. The following diseases comprise the greatest numbers of deaths: heart attacks, asbestosis, silicosis, and stroke. Within the permanent total category, the diseases with the greatest contributions are heart attack, silicosis, strokes, and inflammation of the joints. For the permanent partial category, they are hearing loss, inflammation of joints, carpal tunnel syndrome, and heart attacks. For the temporary total and partial category, they are: inflammation of joints, carpal tunnel syndrome, dermatitis, and toxic poisoning. Hearing loss or inflammation of joints are associated with more than 300 occupations. Circulatory diseases comprise a larger share of job-related diseases than is generally acknowledged. Occupations contributing the most heart attack deaths are truck drivers, managers, janitors, supervisors, firefighters, and laborers. Ratios of numbers of deaths to numbers of disabilities are far higher for illnesses than injuries. Occupations that are consistent in their high ranking on most lists involving a variety of conditions include nonconstruction laborers, janitors, and construction laborers. The large SDS, though dated, provides a tentative national look at the broad spectrum of occupational diseases as defined by WC and the

Radiation recall dermatitis (RRD) is an acute skin toxicity caused by different anticancer or antibiotic drugs within a former completely healed irradiation field. Predictive factors for RRD are not known and its mechanisms are not completely understood. A case of RRD induced by docetaxel and successfully treated by an antioxidant ointment (Mapisal {sup registered}) is presented here. Such an ointment might be useful not only in RRD therapy, but also in the treatment of high-grade dermatitis induced by radiotherapy and thus may contribute to the improvement of patients' quality of life and to the scheduled completion of cancer therapies. (orig.) [German] Die Strahlen-Recall-Dermatitis (RRD) ist eine akute Hauttoxizitaet, die durch verschiedene Chemotherapeutika oder Antibiotika innerhalb eines frueheren, komplett abgeheilten Bestrahlungsfelds hervorgerufen wird. Praediktive Faktoren fuer die RRD sind nicht bekannt und ihr Mechanismus ist nicht vollstaendig geklaert. Es wird ein Fallbericht einer durch Docetaxel induzierten RRD dargestellt, die erfolgreich mit einer antioxidativen Salbe (Mapisal {sup registered}) behandelt wurde. Solche Salben koennten nicht nur zur Therapie der RRD, sondern auch bei der Behandlung einer akuten Dermatitis waehrend der Strahlentherapie nuetzlich sein und damit zur Verbesserung der Lebensqualitaet der Patienten und zur planmaessigen Durchfuehrung der Tumortherapie beitragen.

There are few prospective studies of atopic dermatitis and co-existing diseases such as respiratory infections in children up to 2 years of age. Using annual questionnaires, we studied the cumulative incidence of atopic dermatitis and concomitant symptoms indicating other atopic diseases and respiratory infections in 0-2-year-old children in a prospective birth cohort of 4089 children. We found associations between atopic dermatitis and asthma (ratio of proportion 1.45, 95% CI 1.16-1.80), allergic rhinoconjunctivitis (RP 2.25, CI 1.77-2.85), adverse reactions to foods (RP 3.20, CI 2.83-3.62), urticaria (RP 2.04, CI 1.80-2.31), acute otitis media (RP 1.13, CI 1.05-1.21), more than one pneumonia during the first and/or second year of life (RP 2.17, CI 1.14-4.15), and use of antibiotics at least twice yearly (RP 1.29, CI 1.07-1.56). The association between atopic dermatitis and respiratory infections persisted after stratification for asthma. There was a higher proportion of atopic disease manifestations, but not respiratory infections, in children with onset of atopic dermatitis during the first year of life than during the second. The study shows that during the first 2 years of life there is a significant association not only between atopic dermatitis and other atopic disease manifestations, but also between atopic dermatitis and respiratory infections manifested in an increased rate of acute otitis media, pneumonia and use of antibiotics.

Potential health effects associated with dermal exposure to occupational chemicals.

Science.gov (United States)

Anderson, Stacey E; Meade, B Jean

2014-01-01

There are a large number of workers in the United States, spanning a variety of occupational industries and sectors, who are potentially exposed to chemicals that can be absorbed through the skin. Occupational skin exposures can result in numerous diseases that can adversely affect an individual's health and capacity to perform at work. In general, there are three types of chemical-skin interactions of concern: direct skin effects, immune-mediated skin effects, and systemic effects. While hundreds of chemicals (metals, epoxy and acrylic resins, rubber additives, and chemical intermediates) present in virtually every industry have been identified to cause direct and immune-mediated effects such as contact dermatitis or urticaria, less is known about the number and types of chemicals contributing to systemic effects. In an attempt to raise awareness, skin notation assignments communicate the potential for dermal absorption; however, there is a need for standardization among agencies to communicate an accurate description of occupational hazards. Studies have suggested that exposure to complex mixtures, excessive hand washing, use of hand sanitizers, high frequency of wet work, and environmental or other factors may enhance penetration and stimulate other biological responses altering the outcomes of dermal chemical exposure. Understanding the hazards of dermal exposure is essential for the proper implementation of protective measures to ensure worker safety and health.

Dermoscopic findings in scalp psoriasis and seborrheic dermatitis; Two new signs; Signet ring vessel and hidden hair

2015-01-01

Full Text Available Background: Psoriasis and seborrheic dermatitis are both chronic erythemato-squamous dermatoses that can involve the scalp. It may be difficult to differentiate these two diseases when there is isolated scalp involvement. Recently, trichoscopy is commonly used to differentiate noncicatricial alopecias including psoriasis and seborrheic dermatitis that can lead to telogen effluvium (TE. Objectives: The objective of this study is to evaluate the trichoscopic figures that may help to differentiate scalp psoriasis and seborrheic dermatitis. Materials and Methods: Thirty one with scalp psoriasis and 112 patients with seborrheic dermatitis were enrolled. Trichoscopic examinations were performed using a videodermatoscope (MoleMax 3 ® . Trichoscopic findings of scalp psoriasis and seborrheic dermatitis were compared with each other, with 100 healthy individuals and with other noncicatricial alopecias including female androgenetic alopecia (FAGA (n: 138, male androgenetic alopecia (n: 63, FAGA of male pattern (FAGA.M (n: 5, alopecia areata (39, TE (n: 22 and trichotillomania (n: 4. Results: Atypical red vessels, red dots and globules (RDG, signet ring vessels (SRV, structureless red areas and hidden hairs (HH were statistically more common in psoriasis while twisted red loops and comma vessels (CV in seborrheic dermatitis. RDG were considered as the characteristic videodermatoscopic figure for psoriasis and arborizing red lines and CV for seborrheic dermatitis. In comparison with previous reports, our study yielded two new trichoscopic structures supporting the diagnosis of psoriasis; HH and SRV. Besides, according to our study, CV were described for the first time in seborrheic dermatitis and considered to be specific for seborrheic dermatitis. Conclusion: This study confirmed that trichoscopy might be useful in differentiating scalp psoriasis and seborrheic dermatitis from each other and from other noncicatricial alopecia with three trichoscopic

A 52-year-old woman had been treated with radiation therapy for lymphoid tuberculosis on the right side of the neck 40 years before. Chronic radiation dermatitis occurred on that site. Blackish small mass has appeared 2 years before on the central part of the dermatitis. Histological examination revealed thinning of the epidermis, swelling of the dermal collagen fibers, and follicular clusters composed of basaloid cells from the epidermis to the upper layer of the dermis.

The aim of this study was to characterize T cells in the skin of cats with an allergic dermatitis histologically compatible with atopic dermatitis, since T cells play an important role in the pathogenesis of atopic dermatitis in humans. We observed a significantly greater number of T cells in lesional skin of domestic short-haired cats with allergic dermatitis (n = 10; median age 5.8 years) than in the skin of healthy control animals (n = 10; median age 5.0 years). In the skin of the healthy control animals, one or two CD4+ cells and no CD8+ cells were found. A predominant increase of CD4+ T cells and a CD4+/CD8+ ratio (mean +/- SD: 3.9 +/- 2.0) was found in the lesional skin of 10 cats with allergic dermatitis. The CD4+/CD8+ cell ratio in the skin of healthy control animals could not be determined because of the absence of CD8+ cells. The CD4+/CD8+ cell ratio in the peripheral blood of 10 cats with allergic dermatitis (mean +/- SD: 1.9 +/- 0.4) did not differ significantly from that in 10 healthy control animals (2.2 +/- 0.4). The CD4+/CD8+ cell ratio and predominance of CD4+ T cells in the lesional skin of cats with allergic dermatitis is comparable to that found in atopic dermatitis in humans. In addition, the observed increase of CD4+ T cells in the nonlesional skin of cats with allergic dermatitis compared to the skin of healthy cats is similar to what is seen in humans. Cytokines produced by T cells and antigen-specific T cells are important mediators in the inflammatory cascade resulting in atopic dermatitis in humans. This study is a first step to investigate their role in feline allergic dermatitis.

Medical records of 600 dogs diagnosed with atopic dermatitis were reviewed and evaluated with reference to history, geographical distribution, breed predilection, clinical signs and positive reactions to allergens as determined by intradermal skin testing (IDT) manufactured by Artuvetrin Laboratories. In 66.6% of dogs, the age of onset of atopic dermatitis was between 4 months and 3 years. Dogs living in the garden suburb of Budapest were more sensitive to house dust mites, fleas and moulds, and dogs from the western part of Hungary were more sensitive to weeds than to other allergens (p French bulldog, Doberman Pinscher and Bobtail which were over-represented among atopic dogs compared to the breed distribution of the general dog population of a large city in Hungary. Breeds with verified adverse reaction to food were Cocker spaniels, French bulldogs, Bullmastiffs, Bull terriers, St. Bernards, Tervurens, West Highland White terriers and American Staffordshire terriers (p < 0.05). The clinical signs of atopic dermatitis and their occurrence are in accordance with the data described in the literature.

Short communication: Efficacy of copper sulfate hoof baths against digital dermatitis--Where is the evidence?

Science.gov (United States)

Thomsen, Peter T

2015-04-01

Digital dermatitis is a major problem in modern dairy production because of decreased animal welfare and financial losses. Individual cow treatments are often seen as too time consuming by farmers, and walk-through hoof baths have therefore been used extensively to control digital dermatitis. For decades, copper sulfate hoof baths have been used to treat and prevent digital dermatitis. Copper sulfate has been referred to as the industry gold standard when it comes to hoof-bath chemicals. In several scientific studies testing the efficacy of other hoof-care products, copper sulfate has been used as a positive control, thereby indicating that copper sulfate has a known positive effect. However, this may not be the case. A dilemma may exist between (1) copper sulfate generally being perceived as being effective against digital dermatitis and (2) a possible lack of well-documented scientific evidence of this effect. The objective of this study was to evaluate the existing scientific literature to determine whether the efficacy of copper sulfate used in hoof baths against digital dermatitis has in fact been demonstrated scientifically. A systematic literature search identified 7 peer-reviewed journal articles describing the efficacy of copper sulfate in hoof baths as treatment or prevention of bovine digital dermatitis. Only 2 of the 7 studies compared copper sulfate to a negative control; most studies were relatively small, and often no clear positive effect of copper sulfate was demonstrated. In conclusion, the frequent claim that copper sulfate is widely reported to be effective is supported by little scientific evidence. Well-designed clinical trials evaluating the effect of copper sulfate against digital dermatitis compared with a negative control are needed. Until such studies have been made, the efficacy of copper sulfate in hoof baths against digital dermatitis remains largely unproven. Copyright © 2015 American Dairy Science Association.

Atopic dermatitis (AD) is a common, chronic skin inflammatory disorder characterized by perivascular infiltration of immunoglobulin E (IgE), T lymphocytes, and mast cells. The key factors responsible for the pathophysiology of this disease are immunological disorders and defects in epidermal barrier properties. Pruritus, intense itching, psychological stress, deprived physical and mental performance, and sleep disturbance are the hallmark features of this dermatological disorder. Preventive interventions such as educational programs, avoidance of allergens, and exclusive care toward the skin could play a partial role in suppressing the symptoms. Based on the available clinical evidence, topical corticosteroids (TCs) are among the most commonly prescribed agents; however, these should be selected with care. In cases of steroid phobia, persistent adverse effects or chronic use, topical calcineurin inhibitors can be considered as a promising adjunct to TCs. Recent advances in the pharmacotherapeutic paradigm of atopic diseases exploring the therapeutic dominance of nanocarrier-mediated delivery is also discussed in this evidence-based review with regard to the treatment of AD. The present review summarizes the available clinical evidence, highlighting the current and emerging trends in the treatment of AD and providing evidence-based recommendations for the clinicians and health care professionals. Available evidence for the management of pediatric and adult atopic dermatitis (AD; atopic eczema) of all severities is explored. The management of other types of dermatitis, such as irritant contact dermatitis, seborrheic dermatitis, neurodermatitis, perioral dermatitis, stasis dermatitis, and allergic contact dermatitis are outside the scope of current review article. The presented studies were appraised using a unified system called the "Strength of Recommendation Taxonomy (SORT)", which was developed by the editors of several US family medicine and primary care journals

2017-08-28

Atopic dermatitis affects 3-15% of the general dog population and it has been diagnosed by veterinarians up to 58% of dogs affected with skin disease. It is usually a life-long pathology which can be controlled, but it can be seldom cured. The present investigation describes a case study in which lactoferricin and verbascoside are part of a formulation to obtain a dermatological lotion for canine dermatitis treatment. The study was an open-label trial design of two-week treatment. Thirty-eight dogs (23 females and 15 males), with atopic dermatitis and secondary bacterial or yeast overgrowth have been included. During treatment period the total clinical score progressively decreased associated with an improvement in clinical signs. No adverse effects were reported in any of the treated dogs. The present research suggests that daily applications of tested emulsion are effective in reducing bacterial overgrowth and clinical signs in skin folds and atopic dermatitis.

Full Text Available Pellagroid dermatitis is a condition resulting from the deficiency of niacin and/or tryptophan that causes dermatological, gastrointestinal and neurological symptoms. It is very rare in our country, a fact that motivated us to present this case. The patient was a 49-year-old white man diagnosed with pellagroid dermatitis. He also suffered from hypothyroidism, alcohol dependence and had poor eating habits due to his frequent drinking. He had a medical history of hypertension and presented cutaneous manifestations of pellagroid dermatitis. The erythematous and scaly manifestations were located on the back of both arms. They resembled scalded skin; some had an ulcerated and blistered center and were similar to those in the neck, deltoid region and other sites exposed to sunlight. The lesions were permanently cured after vitamin therapy and skin protection from solar radiation.

Hand dermatitis can be a serious health problem in healthcare workers. While a range of skin care strategies and policy directives have been developed in recent years to minimise the risk, their effectiveness and cost-effectiveness remain unclear. Evidence now suggests that psychological theory can facilitate behaviour change with respect to improved hand care practices. Therefore, we will test the hypothesis that a behavioural change intervention to improve hand care, based on the Theory of Planned Behaviour and implementation intentions, coupled with provision of hand moisturisers, can produce a clinically useful reduction in the occurrence of hand dermatitis, when compared to standard care, among nurses working in the UK National Health Service (NHS) who are particularly at risk. Secondary aims will be to assess impacts on participants' beliefs and behaviour regarding hand care. In addition, we will assess the cost-effectiveness of the intervention in comparison with normal care. We will conduct a cluster randomised controlled trial at 35 NHS hospital trusts/health boards/universities, focussing on student nurses with a previous history of atopic disease or hand eczema and on nurses in intensive care units. Nurses at 'intervention-light' sites will be managed according to what would currently be regarded as best practice, with provision of an advice leaflet about optimal hand care to prevent hand dermatitis and encouragement to contact their occupational health (OH) department early if hand dermatitis occurs. Nurses at 'intervention-plus' sites will additionally receive a behavioural change programme (BCP) with on-going active reinforcement of its messages, and enhanced provision of moisturising cream. The impact of the interventions will be compared using information collected by questionnaires and through standardised photographs of the hands and wrists, collected at baseline and after 12 months follow-up. In addition, we will assemble relevant economic data

Allergic contact dermatitis to fragrance: a review.

Science.gov (United States)

Scheinman, P L

1996-06-01

Allergy to fragrance is the most common cause of cosmetic contact dermatitis and therefore constitutes a significant clinical problem. The widespread use of fragranced materials in skin care and household products is probably the most important reason for the high incidence of fragrance sensitization. This report will summarize the history of fragrance, review how to detect and evaluate fragrance allergy, discuss the problems inherent in patch testing with the fragrance mix and its constituents, describe systemic contact dermatitis from ingestion of certain flavors, and give suggestions for fragrance-sensitive patients. The use of fragrance mix in patch testing has been invaluable in detecting fragrance allergy. Continued investigation into positive patch test responses to fragrance in scented products is essential in helping to identify new fragrance allergens. Additionally, more cooperation is necessary between industry and dermatologists in assisting patients to avoid proven allergens.

The effect of a homoeopathic complex on atopic dermatitis in children

OpenAIRE

2013-01-01

M.Tech. (Homoeopathy) Atopic dermatitis (atopic eczema) is a chronic, relapsing, allergic inflammatory skin disease (Hauk, 2008). The prevalence of atopic dermatitis has increased significantly over the past few decades, with highest rates of 45 – 64% occurring amongst preschool children (Butler, 2009), and 40% amongst older children and adults (Manjra, 2005). This increase in prevalence is attributed to environmental factors such as microbial exposure and poor nutrition, which can all lea...

Cross-sectional studies have suggested that prenatal farm exposures might protect against allergic disease and increase the expression of receptors of the innate immune system. However, epidemiologic evidence supporting the association with atopic dermatitis remains inconsistent. To study the association between prenatal farm-related exposures and atopic dermatitis in a prospective study. We further analyzed the association between the expression of innate immune genes at birth and atopic dermatitis. A total of 1063 children who participated in a birth cohort study, Protection against Allergy-Study in Rural Environments, were included in this study. Doctor diagnosis of atopic dermatitis was reported by the parents from 1 to 2 years of age by questionnaire. Gene expression of Toll-like receptors (TLRs) and CD14 was assessed in cord blood leukocytes by quantitative PCR. Maternal contact with farm animals and cats during pregnancy had a significantly protective effect on atopic dermatitis in the first 2 years of life. The risk of atopic dermatitis was reduced by more than half among children with mothers having contact with 3 or more farm animal species during pregnancy compared with children with mothers without contact (adjusted odds ratio, 0.43; 95% CI, 0.19-0.97). Elevated expression of TLR5 and TLR9 in cord blood was associated with decreased doctor diagnosis of atopic dermatitis. A significant interaction between polymorphism in TLR2 and prenatal cat exposure was observed in atopic dermatitis. Maternal contact with farm animals and cats during pregnancy has a protective effect on the development of atopic dermatitis in early life, which is associated with a lower expression of innate immune receptors at birth.

Purpose: Radiotherapy induced dermatitis is a common and sometimes serious side effect. We conducted a randomized study to understand whether the adjunctive use of aloe vera gel might reduce the prevalence and/or severity of radiotherapy induced dermatitis. Methods: One hundred patients with newly diagnosed breast cancer were randomized to receive aloe vera gel or nothing during adjuvant radiotherapy consisting of conventional external beam radiation using 6 MV mega voltage linear accelerator photons. The radiation portals were composed of breast fields in all patients and supraclavicular and posterior axillary fields in node positive cases. The total dose was 50 Gy with a daily fraction of 2 Gy, five fractions per week. Results: Dermatitis was first found among patients of both groups after week 2. In the aloe vera and control groups, 2/8 patients and 5/12 patients had dermatitis grade 1 after weeks 2 (P value = 0.240) and 3 (P value = 0.317). After the 4th week, the numbers were 18 and, 23 fordermatitis grade 1 and only 1 for grade 3 dermatitis (P value = 0.328). After the 5th week, 31, 12 and 2 patients in the aloe vera group and 36, 6 and 5 of the controls had grades 1, 2 and 3 dermatitis, respectively (P value = 0.488). Conclusion: Aloe vera exerted no positive effect on prevalence orseverity of radiation dermatitis in this study. Creative Commons Attribution License

Lesional skin of cats with allergic dermatitis has a cellular infiltrate and a CD4/CD8 ratio comparable to that in humans with atopic dermatitis. CD4+ helper T cells and in particular cells belonging to the Th2 subset play an important role in disease pathogenesis in humans. We investigated the cytokine pattern of CD4+ T cells in situ, with special emphasis on the putative presence of cells producing interleukin 4 (IL4), in cats with allergic dermatitis. Immunohistochemical procedures were used to determine that CD4+ T cells in lesional and nonlesional skin of cats with allergic dermatitis can produce IL4, as occurs in humans. Lesional and nonlesional skin of cats with allergic dermatitis had significantly more IL4+ T cells (P = 0.001) than did skin of healthy control cats. Double staining indicated that all IL4+ cells were positive for pan-T or CD4 markers. Double labeling for mast cell chymase and IL4 stained primarily different cells. Western blotting demonstrated cross-reactivity between the antibody against human IL4 and a feline recombinant IL4. These results indicate that IL4 is primarily produced by CD4+ T cells and is also present in clinically uninvolved skin, indicating a role in the pathogenesis of allergic dermatitis in cats.

Construction workers are at increased risk of work-related ill-health (WRI) worldwide. To compare the incidence of medically reported WRI in occupations within the UK construction industry according to job title. We calculated standardized incidence rate ratios (SRRs) using WRI cases for individual job titles returned to The Health and Occupation Reporting network by clinical specialists and UK population denominators. We counted frequencies of reported causal exposures or tasks reported by clinical specialists, occupational physicians and general practitioners. We found significantly increased incidence of WRI compared with other workers in the same major Standard Occupational Classification, i.e. workers with similar levels of qualifications, training, skills and experience, for skin neoplasia in roofers (SRR 6.3; 95% CI: 3.1-13.1), painters and decorators (2.1; 95% CI: 1.2-3.6) and labourers in building and woodworking trades (labourers, 6.6; 95% CI: 3.2-13.2); contact dermatitis in metal workers (1.4; 95% CI: 1.1-1.7) and labourers (1.6; 95% CI: 1.1-2.3); asthma in welders (3.8; 95% CI: 2.8-5.0); musculoskeletal disorders in welders (1.7; 95% CI: 1.1-2.8), road construction operatives (6.1; 95% CI: 3.8-9.6) and labourers (2.5; 95% CI: 1.7-3.7); long latency respiratory disease (mesothelioma, pneumoconiosis, lung cancer, non-malignant pleural disease) in pipe fitters (4.5; 95% CI: 3.2-6.2), electrical workers (2.7; 95% CI: 2.4-3.2), plumbing and heating engineers (2.3; 95% CI: 1.9-2.7), carpenters and joiners (2.7; 95% CI: 2.3-3.1), scaffolders (12; 95% CI: 8-18) and labourers (3.3; 95% CI: 2.6-4.1). UK construction industry workers have significantly increased risk of WRI. These data in individual construction occupations can be used to inform appropriate targeting of occupational health resources.

To date, the incident rates of various skin diseases have increased due to hereditary and environmental factors including stress, irregular diet, pollution, etc. Among these skin diseases, seborrheic dermatitis and psoriasis are a chronic/relapsing dermatitis involving infection and temporary alopecia. However, they typically exhibit similar symptoms, thus resulting in difficulty in discrimination between them. To prevent their associated complications and appropriate treatments for them, it is crucial to discriminate between seborrheic dermatitis and psoriasis with high specificity and sensitivity and further continuously/quantitatively to monitor the skin lesions during their treatment at other locations besides a hospital. Thus, we here demonstrate a mobile multispectral imaging system connected to a smartphone for selfdiagnosis of seborrheic dermatitis and further discrimination between seborrheic dermatitis and psoriasis on the scalp, which is the more challenging case. Using the system developed, multispectral imaging and analysis of seborrheic dermatitis and psoriasis on the scalp was carried out. It was here found that the spectral signatures of seborrheic dermatitis and psoriasis were discernable and thus seborrheic dermatitis on the scalp could be distinguished from psoriasis by using the system. In particular, the smartphone-based multispectral imaging and analysis moreover offered better discrimination between seborrheic dermatitis and psoriasis than the RGB imaging and analysis. These results suggested that the multispectral imaging system based on a smartphone has the potential for self-diagnosis of seborrheic dermatitis with high portability and specificity.

Full Text Available Background: Psoriasis has different clinical variants, which mimic diverse dermatological conditions and may require a histopathological confirmation of the diagnosis. Studies to establish a clinicohistopathological concordance (and its determinants, in psoriasis and psoriasiform dermatitis are lacking . Aims : The present study was designed (a to correlate the clinicohistopathological features of psoriasis and psoriasiform dermatitis, and (b to identify determinant(s that may contribute to the diagnosis of psoriasis and psoriasiform dermatitis. Methods : This was a prospective study involving 100 patients, with a single clinical diagnosis of psoriasis or with psoriasis as one of the differential diagnoses, and its correlation with histopathological features. Results : The clinical features of typical scale (P = 0.0001 and Auspitz′s sign (P = 0.0001, and histological evidence of suprapapillary thinning (P = 0.0001 and absent granular cell layer (P = 0.0001 were found to be statistically significant contributors to the clinicohistological concordance in cases of psoriasis. Vertical orientation of collagen bundles (P = 0.0001 and lymphocytic exocytosis (P = 0.003 were found to be significantly associated with diagnosis of psoriasiform dermatitis. Conclusion : The present study reconfirms the diagnostic accuracy of silvery white scale, Auspitz′s sign, and Koebner′s phenomenon in a clinical setting suggestive of psoriasis. However, in their absence, histological evidence of suprapapillary thinning and absent granular layer, in addition to the Munro microabscess and Kogoj′s abscess, may contribute to the diagnosis of psoriasis. Similarly, vertical orientation of collagen bundles and lymphocytic exocytosis may point toward a diagnosis of psoriasiform dermatitis.

Dermatitis associated with ileostomy is an important problem that affects many people, especially children. The aim of this study was to investigate the therapeutic effects of ozone on dermatitis due to ileostomy, and to develop an alternative treatment option. A total of 28 rats were divided into 4 groups: control, ileostomy, ozone, and zinc oxide. Ileostomy was performed in all rats except the control group. After a 1-week waiting time, the ozone group was administered ozone therapy and the zinc oxide group was administered zinc oxide cream locally once a day for a total of 7 days. All rats were sacrificed at the end of this period. The efficacy of treatment was examined by biochemical, histopathological, and immunohistochemical parameters. The levels of malondialdehyde (MDA), total glutathione (tGSH), total antioxidant capacity (TAC), and total oxidant status (TOS) were measured from tissue. Vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen (PCNA) were examined immunohistochemically. Dermatitis occurred pathologically in all rats that underwent ileostomy surgery. The lowest dermatitis score was in the ozone treatment group (p<0.05). Ileostomy dermatitis caused increased levels of MDA and TOS. Ozone treatment resulted in reduced MDA and TOS levels, while the levels of tGSH and TAC were increased (p<0.05). Both VEGF and PCNA immunostaining were augmented in the ozone treatment group (p<0.05). Local ozone application may be a good alternative compared to the conventional treatment methods for the prevention of skin lesions that develop after ileostomy.

Although there are several case reports of wet wipe-associated contact dermatitis, the prevalence of wipes as a source of allergic contact dermatitis in larger populations and the responsible allergens are largely unknown. The aim of the study was to determine the prevalence of wet wipes as a source of contact allergy and the most commonly associated allergens in a North American tertiary referral patch test population. Data collected from 2011 to 2014 by the North American Contact Dermatitis Group was used to conduct a retrospective cross-sectional analysis of patient demographics and patch test results associated with the triple-digit source code for "wet wipe." Of the 9037 patients patch tested during the study period, 79 (0.9%) had a positive patch test reaction to an allergen identified with a wet wipe source. The most commonly associated allergens were preservatives, including the following: methylisothiazolinone (MI) (59.0%), methylchloroisothiazolinone (MCI)/MI (35.6%), bronopol (2-bromo-2-nitropropane-1,3-diol) (27.4%), and iodopropynyl butylcarbamate (12.3%). Fragrance (combined) represented 12.3%. Anal/genital dermatitis was 15 times more likely (P contact allergy had their contact allergens detected by the North American Contact Dermatitis Group screening series. Wet wipes are an important source of contact allergy. Preservatives are the main allergens, especially isothiazolinones.

Patients suffering from atopic dermatitis often describe food hypersensitivity. Rising prevalence of food hypersensitivity and severe allergic reactions to foods have been reported, but the data are scarce. Evaluation of food hypersensitivity reactions in patients suffering from atopic dermatitis. The dermatological examination was performed in patients of age 14 years and above and the detailed history was taken concerning the food hypersensitivity. A total of 228 patients were examined-72 men, 156 women, average age 26.2 (SD 9.5) years. The food hypersensitivity reactions were recorded in 196 patients from 228 (86%), no reactions were recorded in 32 patients (24%). Foods with the most often recorded reactions are: Nuts (in 35% of patients), tomatoes (in 20%), and kiwi (in 17, 5%), apples and spices (in 16%), tangerines and oranges (in 15%), capsicum (in 13%), fishes (in 12%), celery (in 9%), and chocolate (in 7%). Food hypersensitivity reactions are recorded in 86% of patients suffering from atopic dermatitis. Nuts, tomatoes, and pollen-associated foods play a role in the majority of patients suffering from atopic dermatitis.

2015-01-01

Full Text Available Skin barrier dysfunction due to deficiency of the skin protein filaggrin is one of the factors involved in the pathogenesis of atopic dermatitis. Objective: to determine the clinical significance of 2282 del CAGT, R501X, R2447X, and S3247X mutations in the FLG gene in children with atopic dermatitis. The investigation included 58 children with atopic dermatitis. A molecular genetic analysis of the four mutations in the FLG gene was done in all the children. In the patients with FLG gene mutations, there was a tendency towards a higher frequency of sensitization to house dust allergens, significantly more often sensitization to cat epidermal allergen, and significantly higher levels of specific IgE to the cat epidermis. Conclusion. Mutations in the FLG gene encoding the protein filaggrin raise the risk for sensitization to domestic and epidermal allergens and, in case of already existing sensitization to the cat epidermis, the patients are found with a high degree of probability to have the high concentration of specific IgE to this allergen. The above fact justifies the need to place special emphasis on measures to eliminate house dust allergens, and cat epidermis allergen in particular, and to personalize approaches to therapy and prevention of atopic dermatitis in children.

Purpose: To assess the rate of serious (>Grade 2, CTCAE 3.0) dermatitis in our head-and-neck cancer (HNC) patients undergoing simultaneous integrated boost intensity-modulated radiotherapy with concomitant cetuximab (SIB-IMRT-cetuximab). We hypothesized a positive association between the radiation dose to the skin and the degree of dermatitis in patients receiving cetuximab. Methods and Materials: Between April 2006 and December 2009, 99 HNC patients underwent SIB-IMRT-cetuximab. In 69/99 (70%), systemic treatment consisted of concomitant cetuximab only, whereas 30 (30%) were switched from concomitant cisplatin to concomitant cetuximab. Treatment-related dermatitis was prospectively monitored. Ninety-nine patients treated with four to seven concomitant cycles of cisplatin only served as an internal control group. The radiation dose delivered to the skin was measured and related to dermal reactions. Results: Grade 3/4 dermatitis developed in 34% of the cetuximab cohort, which was substantially higher than in the control cohort (3%, p < 0.01). No cases of skin necrosis or other fatal events related to cetuximab have occurred so far. A significantly larger mean skin area was found exposed to high radiation doses in patients with severe cetuximab-related dermatitis, compared with those without (p < 0.01). Conclusion: Concomitant cetuximab resulted in a ∼10-fold increase in the rate of severe transient dermatitis compared with the use of concomitant cisplatin. We found a positive association between the incidence of Grade 3/4 dermatitis and the radiation dose delivered to the skin in patients receiving cetuximab.
