Background: Olanedine solution is a new antiseptic, and several cases of allergic contact dermatitis caused by the agent were reported in 2018; however, these cases were diagnosed based on positive results in 2‐day closed patch testing of Olanedine solution "as is." Objectives: To present another case of Olanedine‐induced allergic contact dermatitis and to analyze the optimal patch‐testing method for this condition. Methods: A 34‐year‐old Japanese female patient and 25 healthy control subjects were patch tested using wet filter paper, which had been treated with 15 μL Olanedine solution, and dried filter paper, which had been treated with 15 μL Olanedine solution and then dried. Results: The patient and all of the control subjects exhibited false‐positive reactions due to irritation in the 2‐day closed patch tests with wet filter paper containing Olanedine solution "as is." The tests with dried filter paper produced a positive reaction on day 7 in the patient, and negative reactions in all control subjects. Conclusions: It is preferable to perform 2‐day closed patch tests using filter paper with the test solution "as is," which had been dried before application in order to correctly diagnose antiseptic‐induced allergic contact dermatitis.

In the past 20 years, there have been numerous reports of skin and mucous membrane disorders allegedly caused by the use of carbonless copy paper, to such an extent that some people in Europe were refusing to work with it and concern was expressed in the European Parliament. In view of its undoubted convenience and superiority over carbon paper, the author was asked by the Commission of the European Communities for a report. Based on visits to manufacturers and users and the investigation of complaints, the conclusion is that, as exposure to the constituents of the paper during its manufacture is considerably greater than in its use and no cases have arisen in his experience in the industry, the complaints are more likely to be attributable to "sick building syndrome" than to the specific effect of any component of the paper.

Carbonless copy paper, or 'no carbon required' (NCR) paper, has often been implicated as the cause of skin, respiratory, or general symptoms, but allergy has been verified in only a cases. A 43-year-old machinist whose work involved the manufacture of NCR paper developed occupational dermatitis on the hands. On patch testing, both the NCR paper and 1 of the chemicals used to produce the microcapsules of the NCR paper, namely diethylenetriamine (DETA), provoked an allergic reaction. .Analysis of the paper showed that it contained enough DETA to induce allergic contact dermatitis. People who handle NCR paper and develop symptoms of contact dermatitis should be patch tested with DETA. [ABSTRACT FROM AUTHOR]

Background: Finn Chambers AQUA (FCA) is a development of the Finn Chambers (FC) test system in which the test chambers are mounted on a moisture‐resistant adhesive patch. FCA has pre‐fixed filter papers. Because the use of FCA does not require any extra taping or use of separate filter papers, a change from FC to FCA chambers may be beneficial for both patients and patch test technicians. Objectives: To investigate whether there are any differences regarding detection of contact allergy when simultaneous patch testing is performed with FC and FCA. Materials and Methods: Results from 434 dermatitis patients simultaneously tested with 10 allergens in both FC and FCA were evaluated. Results: There were no significant differences regarding detection of positive reactions between the two test systems. There were significantly more doubtful reactions to methylisothiazolinone, fragrance mix I and hydroperoxides of linalool when testing with FCA. We only observed significantly more doubtful reactions in FC regarding nickel(II)sulfate. Irritant reactions to formaldehyde were also significantly more common when using FCA. Conclusion: The FC and FCA had good agreement in detection of positive reactions. However, the results including doubtful and irritant reactions justify further research regarding optimization of the dose. [ABSTRACT FROM AUTHOR]

A nonatopic Female secretary developed hand dermatitis after 1 year of full-time work with telefax paper. Her dermatitis improved on sick leave and vacation and relapsed at work. Patch testing showed allergic reactions to several fragrances, balsam of Peru, colophony and neomycin. In 3 patch test sessions, her own telefax papers gave a doubtful reaction which persisted for 4 days, but it could not be determined whether the reactions were allergic or irritant. The colophony content of the telefax paper was about 1% and it was possible that colophony in the telefax paper was responsible for the weak patch test reactions. Accordingly, the contact dermatitis would have been allergic. The patient has now been relocated, does not handle telefax paper, and is symptomless. We concluded that our patient bad an occupational hand contact dermatitis induced by telefax paper and possibly caused by colophony allergy. [ABSTRACT FROM AUTHOR]

The Copenhagen Telephone Company uses 800,000-900,000 sets of no carbon required paper per year. Since 1977 the employees have related itching, dermatitis and symptoms from the mucous membranes to contact with the paper. In 35 employees a total of 4000 epicutaneous tests were performed with negative results. A questionnaire study of 2400 in the company revealed a close relationship between the symptoms and the work intensity with the NCR paper. [ABSTRACT FROM AUTHOR]

Keywords: adhesive; allergic contact dermatitis; case report; Finn Chambers AQUA; modified colophonium; patch test Allergic reactions to traditional Finn Chambers are mainly caused by contact allergy to aluminium, and, in most cases, are verified by positive patch test reactions to aluminium salts.[[1], [6], [11]] Our two cases, however, had negative test results with aluminium chloride hexahydrate, making aluminium contact allergy unlikely. In one report, a diagnosis of aluminium contact allergy was made; however, aluminium salts were not tested.

An over 2 × fold increase in para-aminoazobenzene allergy was observed in patients with allergic contact dermatitis during the years 1990-1991. Presuming that an increase in colour-printed news-papers might be a new recognized source of clinical allergy to azo dyes, patch tests were performed in 32 patients with an established p-aminoazobenzene allergy using a series of important azo dyes used in offset printing ink (Pigment Yellow 12, Pigment Yellow 13, Pigment Red 53, Pigment Red 57), as well as with dye-containing inks and specimens of colour-printed newspaper containing these azo dyes. In 25 out of the 32 patients (78%), positive patch tests were seen to textile an dyes, in particular in Disperse Orange 3(24 patients) In none of the 32 patients were reactions observed to the azo dyes used in printing ink, to the inks used or to the colour-printed paper specimens. indicating that these product were apparently not a cause of Contact dermatitis in our group of patients with azo dye sensitization.

We inform about a case of occupational allergic contact dermatitis (OACD) to methyldibromoglutaronitrile (MDBGN) in industrial hand degreasing moist toilet paper. To our knowledge, this is the first published case of OACD to MDBGN in industrial hand degreasing toilet papers. A cause–effect relationship seems to be clearly established. We believe that physicians must keep in mind that MDBGN is a strong allergen either mixed or as a single component of industrial moist toilet papers. MDBGN must be taken into account for OACD at an appropriate work environment. [ABSTRACT FROM AUTHOR]

Our patient was a 24-year-old female textile cutter who had a conjunctivitis and an erythematous itching dermatitis of the eyelids, nasal mucous membranes and the corners of the mouth. The patch tests with the standard series and a pharmaceutical test battery were negative. Further epicutaneous testing revealed a strong positive reaction to the textile cutting patterns she handled, which were duplicated by diazo processing. Specifically, the contact dermatitis reaction was caused by dimethylthiourea, an additive in diazo-sensitized paper. [ABSTRACT FROM AUTHOR]

The results of patch tests with colophony in the standard series between 1983 and 1987 were analyzed. 5521 patients were tested in the Department of Dermatology, Hamburg, while 354 were tested in other clinics and private practices. Colophony was positive in 2.4% and 11.9%, respectively. Out of 62 patients in the 1st group and 75 in a 2nd group tested subsequently with 6 unmodified types of colophony and 12 types of modified-colophony products, 17 did not react to the unmodified material. However, most of them responded to 1 or more of the modified products. In the enlarged group (n = 75), reactions to Abitol® and the maleic-modified products were the most frequently obtained. As the authors are convinced that the actual incidence of allergic reactions to modified-colophony products is underestimated, they propose to test a mixture of 3 materials: Chinese colophony (today 50% of the world market) and 2 derivatives (modified colophony), instead of the 60% mix of unmodified colophony, in the standard series.

This article presents a case of allergic contact dermatitis on the hands from chloromethylisothiazolinone in moist toilet paper. A 28-year old married woman had developed fissured lesions on her hands which became more severe with the development of erythematous, pruriginous, vesicular lesions. She reportedly used moist toilet paper for her baby's hygiene. She was patch tested with a standard series, which was positive to Kathon CG (5-chloro-2-methyl-4-isothiazolin-3-one). A patch test with the moist toilet paper was also positive. Out of 19 brands of moist toilet paper whose information was collected from Spain, eight did not contain Kathon CG. The case is therefore concerned with a patient using moist toilet paper not of her own hygiene but for that of her baby, resulting in allergic contact dermatitis on the hands, a hitherto unreported localization.

We describe 4 adults with an allergic contact dermatitis for moist baby toilet tissues, being used either for their personal hygiene or for their babies (children). The allergen proved to be the preservative mixture of methylchloroisothiazolinone and methylisothiazolinone (MCI/MI). Allergic contact dermatitis from moist toilet paper has been infrequently reported but is probably not rare. The cases we describe here have been observed over a short period of 6 months. The question arises if the use of MCI/MI as a preservative, still often used in leave-on products, should not be abandoned from cosmetics. [ABSTRACT FROM AUTHOR]

This article presents the case of a 53-year old female former hairstylist with no personal and family history of skin disease or atopy who was diagnosed with allergic contact dermatitis due to diazo copy paper. She had worked for 4 years in heliographic printing. She copied original drawings using the diazo-method, and was therefore in contact with copy paper coated with diazodiethylaniline chloride. 2 weeks after starting the job, a squamous dermatitis appeared on the tips of the thumbs, index and middle fingers of both hands, which were exposed to diazo paper. Away from work on treatment, the dermatitis resolved in a few days. After starting work again, she developed dermatitis at the same sites 3 weeks later.

2.3-epoxypropyl trimethyl ammonium chloride (EPTMAC) is used in the production of cationic starch (CS) for the paper industry. It has been shown to be a sensitizer in guinea pigs, but cases of human sensitization are few: 4 workers were previously sensitized to the substance in a Finnish plant. This report describes 3 process men from another plant examined because of recurring dermatitis. 18 workers were involved in production, and had free access to all work site. 3 process men, whose work involved drying the CS, had dermatitis, although they had only occasional contact with the cationizing chemical, 2 were already verified to be allergic to EPTMAC and had variable dermatitis for 8 12 years. One had dermatitis on his face for 1 year. Patch testing with a dilution series (1%, 0.5%, 0.2%, 0.1% pet) confirmed their allergy to the cationizing chemical containing EPTMAC, but test with CS were negative. In addition, 2 had contact allergy to CI+Me-isothiazolinone from contact with Kalhon® LX used as a slimicide in the process. In long-standing (years) recurrent dermatitis, re-examination of patients with verified exposure history and skin tests is necessary. In line with our previous study, sampling the process materials, maintenance work and contamination of work sites and gloves caused sensitization. The results also confirm that EPTMAC is a strong human contact sensitizer. 0.2%-0.5% pure EPTMAC in pet, seems to be the optimal patch test concentration. [ABSTRACT FROM AUTHOR]

The allergens most commonly identified have been the unexposed diazo compounds, particularly p-diazodimethylaniline zinc chloride double salt, and thiourea or dimethylthiourea. Diazomethylpyrrolidinobenzene and 2,7-dihydroxynaphthalene have also been reported. Diagnosis of contact allergy due to diazo copy paper is often difficult, since the papers may not only contain the substances mentioned, but up to 40 other constituents.

From 15 May to 15 December 1994, 2943 patients suspected of having contact dermatitis (1955 women, 988 men) were patch tested with methyldibromoglutaronitrile 0.3%, 0.1% and .05% pet. 119 patients (4.0% women, 4.1% men, 3.8%) proved to be allergic. 71% of the reactions were considered to be relevant. In 2/3 of the patients, causative products were cosmetics, in 1/3 moistened toilet tissues. Testing with methyldibromoglutaronitrile at lower concentrations 0.05% and 0.1%) and with commercial allergens (Euxyl® K 400 and methyldibromoglutaronitrile, both containing methyldibromoglutaronitrile 0.1%), resulted in a number of false-negative reactions. All preservatives in the European standard series had lower scores than the 4% positive reactions to methyldibromoglutaronitrile (formaldehyde 2.0%. MCI/MI (Kathon® CG) 3.2% parabens, 1.0% quaternium-15 1.3%). It is concluded that methydibromoglutaronitrile (present in the commercial preservative Euxyl® K 400) is an important contact allergen in the Netherlands in cosmetics and moistened toilet tissues. It should be added to cosmetics series and to proctological series. The optimal test concentration is unknow, but may be 0.3%. pet. Th concentration of 0.1% methyldibromoglutaronitrile in the currently available commercial allergens appears to be too low, resulting in a number of false-negative reactions. [ABSTRACT FROM AUTHOR]

a 43 year-old male Technical Officer was seen in September 1985 when he gave history of skin trouble since the age of 18 years, when he reacted severely to sticking paper following appendicectomy. He complained especially of facial dermatitis which had been recurrent for several years. The contact dermatitis of his face and hands was due to pinus radiata sawdust with which he came in contact in a woodwork hobby. A patch test to a perfumed handkerchief was negative, but it seems more likely that the condition was the result of repeated contact with the perfume in the handkerchief.

This article presents a case study of a 5-year-old bank clerk who developed a squamous dermatitis on the tips of his right thumb and index finger, which were continually exposed to paper money. This worsened in 1989, after new German banknotes were issued. It improved within a few weeks when he was not at work. A few days after resuming work, dermatitis reappeared in the same places. During the next 5 years, the eczema continued to worsen when he was in contact with banknotes. However, patch tests were performed to see the effective change in his skin.

The article presents a case report of a 37-year-old orthopaedic surgeon who consulted the Department of Dermatology for widespread eczema. His eczema started on the arms and spread to the neck and entire body. He suspected paper-based surgical clothing as the cause. The eczema deteriorated during periods of intensive work and improved during days out of the operating theatre. The patient also reacted positively to both the acetone extract and the extract in pet. When he subsequently reverted to textile-based surgical clothing, his contact dermatitis improved.

This article discusses about a patient who developed itchy dermatitis in hands due to exposure to phenolformaldehyde resin. The patient had to remove the end product from the press. Recently he developed an itchy dermatitis of the dorsa of the hands and was patch tested. He reacted to balsam of Peru, the phenolformaldehyde resin used for impregnation of the paper sheets. The patient was then tested with a number of possible monomers and reacted to all of them. It is difficult to decide which of the substances acted as inducer of contact sensitization in the patient. It depends on the sensitizing capacity of each in the resin vehicle and on the effective mode of exposure.

Two female patients with histories of contact dermatitis to nickel-containing jewelry (dime-thyiglyoxime test positive) failed to react to patch testing with 5 % nickel sulphate in yellow petrolatum. Further patch testing was performed with nickel sulphate 2.5 % and 5 % in water and with 2.5% in DMSO 50%, but no positive reactions were obtained. An intradermal test with a 1/10,000 dilution in water was also negative. Both patients were again patch tested with 10% nickel sulphate in yellow petrolatum, which resulted in ++ reactions after 48 and 96 hours.

A 41-year-old man developed hand dermatitis, which has persisted for 4 years. The dermatitis commenced on the dorsa of the hands and spread to the palms and later to the feet. He had previous contact with cement and other building materials and his work had been photocopying architectural and technical plans for the last 5 years. Sensitivity to thiourea has also been observed in two patients working with plan printing materials and presenting with photodermatitis. Patch testing with thiourea showed sensitivity, in one case with and the other without exposure of the test site to light. Dermatitis and photosensitivity settled slowly after contact with thiourea ceased.

In December 1990. a paper mill worker presented with a 3 month history of sore itching upper and lower eyelids, with erythema and scaling. The reaction occurred at least 4 hour after finishing work and lasted for more than 24 hour. It began only after the paper mill changed biocides to Busan 79 and Busan 1058. Patch testing with Finn Chambers on Scanpor tape was negative to the European standard series and Busan 79 0.01% pet. The paper mill changed the biocide, and he has remained free of dermatitis since.

This article focuses on the analysis of the sensitization level of chemicals containing methylene-bis-thiocyanate to human contact. Slimicides containing methylene-bis-thiocyanate are widely used in the paper industry. In order to evaluate the risk of sensitization, patch tests were performed on 34 exposed workers. The patch tests were performed with 25 substances, with Cytox® 3522 0.2% in pet. The patch tests were applied for 24 hours and read on the third and fifth days. The results of this study show that chemicals containing methylene-bis-thiocyanate, although widely used as slimicides in the paper industry, are not strong.

This article presents a study on headspace analysis of gases and vapors emitted by carbonless paper. The emission of gases and vapors was investigated hy headspace analysis at 50°. The samples were analyzed by gas chromatography and mass spectrometry using 100 m CW2OM capillar column and temperature program. The result of the analysis showed that more than 42 chemicals degassed from the paper samples. The same compounds were found in the two headspaces hut the total concentration was seven times higher around the manufacturer's sample then around the other. An indication of a difference between the two paper samples was found by an indirect measurement of the santasol oil content in the papers. This was done by comparing the concentrations or volatile trace compounds found both in the santasol sample and the headspaces around the paper samples.
