Occupational Contact Dermatitis Risk Factors on Healthcare Workers Isolation Ward During the COVID-19 Pandemic

Background: After a history of exposure to the suspected material and a thorough physical examination, the diagnosis of occupational contact dermatitis (OCD) is commonly suspected. During the initial consultation, essential information involving the above is frequently neglected. Purpose: To evaluate the clinical manifestations of OCD cases in health workers and analyze the factors that influence OCD cases in health workers at the isolation ward of Dr. Soetomo Surabaya Hospital during the COVID-19 pandemic. Methods: The sample selection was done through purposive sampling. Accessible population that met the inclusion criteria and did not have exclusion criteria were included as research samples. The target population was healthcare workers in the Special Isolation Ward of Dr. Soetomo Hospital Surabaya. The accessible population was healthcare workers who performed hand hygiene activities and used Personal Protective Equipment (PPE) in the Special Isolation Ward of Dr. Soetomo Hospital Surabaya. The research subjects were healthcare workers who worked in the Special Isolation Ward. Result: The research results showed a strong and significant correlation between atopic history and the occurrence of contact dermatitis due to poor skin barrier function and decreased tolerance. The study also found that there was no significant correlation between atopic history and the severity level of OCD. There was a significant difference in transepidermal water loss (TEWL) values in the lesion and non-lesion areas, both on the palmar and dorsal aspects of the hand. Moisturizer is an important component in managing hand dermatitis as it can repair and maintain the skin's protective barrier. Conclusion:

Nickel dust-induced occupational contact dermatitis by welding and grinding work in shipyard workers: a report of nine cases

BackgroundOccupational skin diseases are skin conditions that occur or worsen in relation to work and known to be the second most common type of occupational disease affecting individuals in the United States. In Korea, epidemiological reports related to occupational skin diseases are rare. But, no cases of occupational contact dermatitis caused by welding and grinding work have been reported previously.Case presentationNine male workers working in the production department for liquefied natural gas (LNG) ships in Ulsan complained of erythematous papules/patches and itching in various areas of the body after welding and grinding work. The work environment monitoring report revealed that the amount of nickel dust exceeded the time weighted average (TWA) and poor local ventilation status. Based on the symptoms and the overall results of surveys, several tests, and work environment monitoring report, the 2 workers who had positive patch-test reactions to nickel were diagnosed with nickel dust-induced allergic contact dermatitis. The other 7 workers were diagnosed that there was a high probability that they had nickel dust-induced irritant contact dermatitis. The 2 workers who had nickel dust-induced allergic contact dermatitis were recommended to switch their jobs.ConclusionsNickel is one of the most common cause of allergic contact dermatitis. In this case, the dust was assumed to be created by welding work with a high nickel content new welding rod and subsequent grinding work, and the concentration of this dust exceeded the time weighted average. Thus, it is thought that the nickel dust may have caused contact dermatitis through continuous contact with the workers' exposed skin in a poorly ventilated space. Currently, several domestic shipbuilding companies are manufacturing LNG tankers using a new construction method. Consequently, it is highly likely that similar cases will occur in the future, which makes this case report meaningful.

The History of Surfactants and Review of Their Allergic and Irritant Properties.

Surfactants, many of which are used as detergents, can be found in many common household items, such as shampoos, conditioners, soaps, and cosmetics. One should recognize the multitude of surfactants that are used in today's products to identify any potential allergic contact dermatitis (ACD) or irritant contact dermatitis (ICD). Given their abundance in everyday products, it is understandable that many cases of occupational contact dermatitis that arise can be attributed to surfactants. The products most connected with ACD are cocamidopropyl betaine, oleamidopropyl dimethylamine, decyl glucoside, 3-dimethylaminopropylamine, amidoamine, and cocamide diethanolamine. Similarly, the most common surfactant-related causes of ICD are sodium lauryl sulfate and benzalkonium chloride. It is important for dermatologists to identify the causes and differentiate between the two, to adjust treatments and products accordingly. Here, the most frequently used surfactants, as well as their correlation between ACD and ICD, will be reviewed.

Incidence rates of occupational contact dermatitis in Denmark between 2007 and 2018: A population-based study.

Recent population-based studies on the incidence rates (IRs) of occupational contact dermatitis (OCD) are sparse. To determine the IRs of OCD and development thereof between 2007 and 2018 in known risk occupations. Data on all recognized cases of OCD were used to calculate IRs as the number of recognized OCD cases per 10 000 workers per year. Asymptotic chi-square test was used to compare the IRs between 2007-2012 and 2013-2018. The median age at notification of OCD was below 30 years for several of the examined occupations. Hairdressers and beauticians, bakers, dentists and dental assistants, and manufacturing of windmills had the highest overall IRs of OCD. We found a statistically significant increase in the IRs of OCD for child/nursery care workers. The median age at notification of OCD was low for several of the occupations, signifying the need for further preventive strategies among young people. Based on the IRs of OCD, future preventive efforts should be directed at hairdressers and beauticians, bakers, dentists and dental assistants, and manufacturing of windmills. Furthermore, the statistically significant increase in IRs of OCD among child/nursery care workers highlights the need for further preventive strategies in this field.

FACTORS AFFECTING CONTACT DERMATITIS ON PALM OIL PLANTATION WORKERS OF PT. X IN SEMITAU SUB-DISTRICT

The prevalence of occupational skin diseases reaches 20% up to 70% around the world. Occupational contact dermatitis cases reached 1.3-8.1 per 10,000 full-time workers per year in two decades. This research aims to identify the relationship between predisposing factors, enabling factors, and reinforcing factors on the contact dermatitis cases on palm oil plantation workers of PT. X in Semitau Subdistrict. This study design was a cross-sectional involving 72 samples. The independent variables covered age, gender, level of knowledge, use of Personal Protective Equipment (PPE), tenure, chemical contact, personal hygiene, history of occupational dermatitis, occupational history, and Occupational Safety and Health Management System (SMK3). Then, the dependent variable was occupational dermatitis cases. A total of 54.2% of respondent suffered from occupational dermatitis. Some respondent were elderly (43.1%) and most of the subject were female (62.5%). The respondents had a good level of knowledge (37.5%), good personal hygiene (52.8%), and use complete PPE (25%). A total of 51.4% of respondent did not have chemical contacts and those who have <2 years of tenure reached 45.8%. Most of the subjects did not have an occupational history (81.9%) and occupational dermatitis history (75%). Half of the subjects had a good level of application of SMK3. Chi-Square Test results showed significant values of personal hygiene, use of PPE, and a history of the disease (<0.05) with p values of <0.05. There is a strong relationship between personal hygiene, the use of PPE, and the history of occupational dermatitis on palm oil plantation workers of PT. X in Semitau Subdistrict.

Individualprävention beruflicher Kontaktekzeme: Schutzhandschuhe und Hautschutzempfehlungen im berufsgenossenschaftlichen Heilverfahren

The dermatologist'sprocedure is apivotal 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 arisk 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 Contact Dermatitis in 10,582 French Patients Reported between 2004 and 2007: A Descriptive Study

Background: Limited epidemiological data are available in France for occupational contact dermatitis (OCD), a non- infectious inflammatory skin condition arising from direct skin contact with substances used in the workplace. Objective: To estimate the occurrence of, and number of workdays lost to, OCD in France. Methods: Descriptive study of all OCD declared by salaried workers and recognised as occupational disease in France over a 4-year period. Results: 10,582 OCD cases were reported, representing 9.6% of all occupational diseases recognised. The estimated annual incidence of OCD recognised was 15.72/100,000 salaried workers (i.e. 146.87/100,000 employees for all occupational diseases). OCD cases were mainly in the construction and public works industries with 3,057 (36.7%) salaried workers affected. In the services sector, OCD predominantly affected employees aged less than 30 years (41%), particularly hairdressers (69%). OCD accounted for the loss of 395,069 working days. Conclusion: OCD represents a significant public health problem in France, particularly for construction workers and hairdressers.

Workers with occupational contact dermatitis: workplace characteristics and prevention practices

There are many gaps in knowledge related to prevention practices in place for workers who subsequently develop occupational contact dermatitis (OCD). To describe the workplace characteristics and the prevention practices in workplaces where workers developed hand dermatitis. Consecutive cases of probable OCD were enrolled from a specialist occupational health clinic. At the time of the initial assessment, questionnaires were administered to collect information about clinical presentation, workplace characteristics and prevention practices at work. 100 workers with hand dermatitis were enrolled in the study and 78 were considered to have OCD. Two-thirds of these had had some occupational health and safety or Workplace Hazardous Materials Information System (WHMIS) training in their workplace, however, training related to glove use and skin care was less common. Unionized workers were more likely to have received training. Workers involved in wet work were less likely to report training. These findings suggest that there are gaps in prevention programs for work-related skin disease. Research is needed on effective strategies that are sustainable in the workplace.

Two Recurrent Cases of Occupational Contact Dermatitis in a Cook and a Vegetable Handler after Changing Their Jobs in Japan—How to Improve Pre-employment Counseling?

Two Recurrent Cases of Occupational Contact Dermatitis in a Cook and a Vegetable Handler after Changing Their Jobs in Japan—How to Improve Pre-employment Counseling?

Management of Occupational Dermatitis

Contact dermatitis is the most common occupational skin disorder, responsible for up to 30% of all cases of occupational disease in industrialized nations. Epidemiologic data suggest that contact dermatitis accounts for 90% to 95% of all cases of occupational skin disease, imposing considerable social and economic implications. Occupational contact dermatitis is broadly classified into allergic and irritant subtypes. Irritant contact dermatitis is widely quoted in the literature to account for 80% of occupational contact dermatitis cases, with allergic cases held responsible for the remaining 20%.

Occupational contact urticaria: Australian data

Over the last 30 years there has been increasing recognition of the clinical entity contact urticaria (CU) and the related diagnosis, protein contact dermatitis. However, there are relatively few reports of the occupational relevance of this condition. To describe relevant characteristics of patients diagnosed with occupational CU (OCU) in a tertiary level specialist occupational dermatology clinic in Australia. We performed a retrospective analysis of all patients diagnosed with OCU at an occupational dermatology clinic in Melbourne between 1 January 1993 and 31 December 2004. We identified 151 cases of CU diagnosed over the 12-year period. OCU was diagnosed in 8.3% (143 of 1720) of the total number of patients with occupational skin disease. Natural rubber latex accounted for the majority of all cases of OCU. Other common causes were foodstuffs and ammonium persulphate utilized as hairdressing bleach. The most commonly affected sites were the hands, followed by the arms and face. The most frequently affected occupations were healthcare workers, food handlers and hairdressers. All cases of CU in patients with hand symptoms were assessed to be work related. Atopy was a significant risk factor for both latex-related and nonlatex-related OCU. Radioallergosorbent tests and skin prick testing, including to patients' own food samples, should be part of the routine assessment of patients in high-risk occupations for OCU, particularly if the hands are affected, there is a history of atopy and there is exposure to urticants. We emphasize the importance of both determining the role of occupation in the causation of CU and recognizing all contributory factors in complex cases of occupational contact dermatitis of the hands.

Occupational dermatitis related to chromium and cobalt: experience of dermatologists (EPIDERM) and occupational physicians (OPRA) in the U.K. over an 11-year period (1993?2004)

Chromium and cobalt (and their compounds) are well recognized as being important causes of occupational contact dermatitis (OCD), particularly of the hands, although their exact contribution to occupational hand dermatitis varies between different studies. In some European studies, cases of chromium-related dermatitis have decreased following the addition of ferrous sulphate to cement to reduce the amount of available chromium. To examine, using data from the U.K. occupational skin surveillance schemes, the proportionate reported incidence and changing trends in OCD considered to be related to chromium and cobalt for the 11-year period from February 1993 to December 2004. Surveillance data collected by the two British occupational health surveillance schemes, EPIDERM and OPRA, from February 1993 to December 2004 were studied. These are occupational health surveillance schemes in the U.K. to which physicians voluntarily and anonymously report new cases of skin disease suspected to be work related. Over the 11-year period, dermatologists reported 22 184 cases of OCD, comprising 77% of all types of occupational skin diseases that were disclosed. Chromium was recorded as being thought to play a role in 1226 (6%) of these, with cobalt identified as being likely to be implicated in 823 (4%). The numbers fluctuated on a year-on-year basis but there were no overall trends during the period of study. The male/female ratio was 5 : 1 for chromium and 1 : 1 for cobalt. Overall, the male/female ratio for OCD was 1.4 : 1. The rates of dermatitis believed to be related to both metals generally increased with age. In women, the highest rate for chromium was seen in the > 60 years age group, whereas conversely, for cobalt the rate decreased with age. For chromium-related OCD the most common occupations were builders and building contractors, bricklayers, construction workers and plasterers. For cobalt-related OCD, the commonest occupations were hairdressers/barbers, builders/building contractors, retail cash/checkout operators, machine operatives and domestic cleaners. Occupational physicians reported 15 016 cases of OCD (82% of all occupational skin diseases reported by them) for the period May 1994-December 2004. Of these, only 38 cases were thought to be related to chromium and 30 to cobalt (25 of the latter were processing labourers). In this series, chromium was reported by dermatologists as potentially being involved in 6% of all cases of OCD in the U.K., and cobalt in 4%. Our data support the view that chromium-related dermatitis has an onset in later working life and often affects those in the building trades, whereas cobalt-related dermatitis seems to have an earlier onset and may affect a wide range of employments.

Occupational contact dermatitis: Etiology, prevalence, and resultant impairment/disability

Cutaneous irritant and allergic responses account for the vast majority of cases of occupational contact dermatitis (OCD). Although the pathophysiologic responses to these two different exposures are distinct, the clinical differentiation between chronic cumulative irritant contact dermatitis and allergic contact dermatitis can be difficult and frequently requires patch testing. This article reviews the recommended algorithms that clinicians should utilize to assess whether a worker suffers from OCD. The prevalence of OCD, its predisposing factors (both endogenous and exogenous), and prognosis are discussed in depth. Finally, issues surrounding the assessment of impairment and disability resulting from OCD are summarized.

FS10.7 A surveillance network for occupational contact dermatitis utilizing general practitioners

Objectives: The Surveillance by General Practitioners of Occupational Contact Dermatitis Project (Spot) has been designed to provide disease estimates for occupational contact dermatitis within a defined geographic area in Melbourne, Australia.Method: Spot collected reports of occupational contact dermatitis from four separate sources: general practitioners, dermatologists, a Dermatology Outpatient clinic, and an Occupational Dermatology Clinic. Case definition was stratified into two levels, suspected and confirmed. All cases of suspected occupational contact dermatitis reported to Spot were assessed and required to undergo diagnostic confirmation, including appropriate patch testing by an occupational dermatologist. The rates generated by Spot were compared to the rates generated by Victorian workers’ compensation data (Victorian Work Cover Authority) for “Contact dermatitis and other and unspecified dermatitis.”Results: To date, a total of 125 suspected cases have been reported to Spot. 56 cases of occupational contact dermatitis have been confirmed with an incidence rate of 12.5 per 100,000 full‐time workers and a prevalence rate of 28 per 100,000. This can be compared to the rate from Victorian WorkCover Authority of 4 per 100,000 (with information not available for incidence or prevalence).Conclusions: Although limited by resources, clinician and worker participation rates, Spot provides a better estimate for occupational contact dermatitis in an Australian urban setting than that currently available through workers’ compensation statistics. The information generated by Spot will provide an important contribution towards the characterisation of occupational contact dermatitis in Australia.

Occupational issues of allergic contact dermatitis.

Occupational contact dermatitis is often of multifactorial origin, and it is difficult to determine the relative significance of the various contributing factors. Contact allergies are relevant in 20-50% of recognised occupational contact dermatitis cases. The reported frequency in different studies varies, depending on differences in how occupational diseases are notified and recognised, in types of occupation in a geographical area, and the "quality" of the dermatological examination, including the accuracy of the diagnostic patch-test investigation. However, the clinical relevance of the reported contact allergies is often uncertain. Many occupational contact dermatitis patients with documented contact allergies develop chronic eczema, in spite of work changes and attempted allergen avoidance. Recognition/non-recognition of a notified case may be based on circumstantial evidence, because of difficulties in the establishing of a firm proof of work exposure and subsequent development of skin disease. Reliable quantitative exposure measuring techniques are needed. Methods are developed for the measurement of exposure to allergens such as nickel and acrylates, which makes it possible for exposure-effect relationships to be established with increased certainty. For prevention of allergic contact dermatitis it was a major step forward, with mandatory ingredient labelling of cosmetic products. However, improved labelling of the presence of contact allergens in household and industrial products is needed. For the identification of hazardous contact allergenic compounds, guinea pig or mice assays are still required. The local lymph node assay (LLNA), which is an objective and sensitive mouse assay has now been internationally validated and accepted.

Prognosis and work absence due to occupational contact dermatitis.

The consequences of a diagnosis of occupational contact dermatitis (OCD) were investigated using cases available from the voluntary surveillance scheme, EPIDERM. Cases of OCD reported from November 1994 to September 1995 were identified and sampled to give at least 100 cases of allergic, irritant and mixed OCD reported by consultant dermatologists (344 cases) and occupational physicians (377 cases). A questionnaire was sent to the reporting physician to elicit further information. 512 completed questionnaires were returned, of which 510 were eligible for analysis. Among cases reported by dermatologists (n = 286) and occupational physicians (n = 224), 7% (6.3%) had been unemployed and 16.8% (20.1%) had taken sick leave. 3 factors independently predicted time off work in a logistic regression analysis: age OR = 1.25 (95% CI, 1.05-1.49), allergic dermatitis OR = 1.77 (95% CI, 1.13-2.79) and medicolegal assessment OR = 4.42 (95% CI, 2.20-8.89). Overall, 15.7% did not improve clinically between the first and last visit. Those who did not improve had been exposed to the agent for longer (mean 7.6 years) than those who did (5.3 years) (p = 0.09). In patients <or= 45 years, those reported to be atopic failed to improve (25.4%) more often than those not atopic (13.4%) (p = 0.04). The substantial numbers (21%) with time off work and with persistent dermatitis suggest that OCD continues to have a significant impact on workers and their employers.
