- Abstract
Background/objectives: In the last 10 years methylisothiazolinone (MI) emerged as a global cause of preservative-related ACD. New Zealand has liberal regulations for the MI concentration limit in cosmetic products compared to Europe and Australia. The aim of this study was to evaluate the prevalence of MI sensitisation in New Zealand, explore sources of MI exposure and make recommendations on New Zealand regulations for MI use., Methods: This retrospective study included data from patients who underwent patch testing with MI from 2008 to 2021 in a tertiary hospital dermatology clinic and a private dermatology clinic in Auckland, New Zealand. Patient baseline characteristics were recorded along with results of patch testing. Sources of MI exposure were identified from medical records., Results: Over the study period, 1049 patch tests were performed in 1044 patients. MI was only tested as a stand-alone allergen from 2015; positive reactions to MI increased from 5.3% in 2015 to a peak of 11.9% in 2017 and then decreased to 6.4% in 2021. The most common source of MI exposure was shampoo or conditioner (27.7% of all relevant reactions) followed by occupational exposures to paints, biocides or glue (19.1%)., Conclusion: Both sensitisation and ACD to MI appear to be decreasing, likely secondary to changes in product compounding due to stricter concentration limits internationally. We recommend New Zealand adopt lower MI concentration limits for cosmetics to match the limits of Australia and Europe., (© 2024 Australasian College of Dermatologists.)

Isobornyl acrylate (IBOA) has recently caused a number of cases of allergic contact dermatitis (ACD) from its use in medical devices. We would like to enhance the awareness of this issue with the reporting of three Australian cases, involving two adults and a child. We also report a successful solution by using hydrocolloid wafer (Stomahesive®) as a barrier. As IBOA is not usually found on baseline patch test series and does not cross‐react with other acrylic monomers, ACD to IBOA may be missed by clinicians. [ABSTRACT FROM AUTHOR]

CONTACT dermatitis - Abstract
Despite being a well‐recognised cause of allergic contact dermatitis with an embargo in many countries around the world, bufexamac is available over the counter in topical preparations in Australia. We present a series of patients who developed severe cutaneous eruptions after the topical application of bufexamac containing preparations to highlight the potential risks of this medication, as well as advocate for the reconsideration of its registration by the Therapeutic Goods Administration in Australia.

BACKGROUND Patch testing is the gold standard diagnostic test for allergic contact dermatitis and needs to be relevant to the region and the population being tested. The aim of this study was to develop a specific New Zealand baseline series (NZBS). METHOD We performed a retrospective case note review of patients attending four regional patch test centres between 2008 and 2020. Demographic and diagnostic information was collected for each patient along with results of patch testing. Using the results of this review, a group of 11 dermatologists with an interest in contact dermatitis agreed on a core group of allergens for inclusion in an NZBS, based on the frequency of positive reactions and allergens of interest. The remaining potential allergens were ranked by each dermatologist using an online questionnaire, with inclusion in the final NZBS by consensus. RESULTS Results from 2402 patients (67% female, mean age 44 years) from Auckland, Wellington, Palmerston North and Christchurch were collated. The 10 most frequent positive (relevant and non-relevant) allergens were nickel sulfate (22.0%), fragrance mix I (8.6%), cobalt chloride (7.3%), Myroxylon pereirae (5.6%), colophonium (5.1%), p-phenylenediamine (4.9%), methylisothiazolinone/methylchloroisothiazolinone (4.1%), fragrance mix II (3.9%), potassium dichromate (3.5%) and methylisothiazolinone (3.4%). Based on these results, a core series of 30 allergens was developed, with an additional 30 allergens added to form the extended series (total 60 allergens). CONCLUSION The baseline series of patch test allergens for routine use in New Zealand (NZBS) is based on national patch test data and expert consensus.

Background Patch testing is the gold standard for the diagnosis of allergic contact dermatitis (ACD). The Australian Baseline Series (ABS) was formulated by our group to include the 60 most common and relevant allergens in our patient population. The aim of this study was to assess the efficacy of testing with the Australian Baseline Series in order to diagnose allergic contact dermatitis. Methods We conducted a retrospective study of 964 patients with ACD diagnosed at our centre from 1 January 2012 to 31 December 2018. Patients with at least one relevant positive reaction were stratified into three groups: i) reactions only to allergens in the Australian Baseline Series; ii) reactions to allergens in the Australian Baseline Series and to additional allergens; and iii) reactions only to allergens not present in the Australian Baseline Series. Results The Australian Baseline Series alone was successful in identifying the cause of allergic contact dermatitis in 63.4% (611/964) of patients. In 23.0% (222/964), the Australian Baseline Series detected at least one relevant allergen, but there were relevant allergens outside of the Australian Baseline Series as well. In 13.6% (141/964), no relevant allergens were detected in the Australian Baseline Series, but allergens were detected in additional series or by testing patients' own products. The most frequently occurring allergens not included in the Australian Baseline Series were citral, ammonium persulfate, geraniol, oakmoss absolute and chlorhexidine diacetate. Conclusions The Australian Baseline Series is an adequate screening tool for identifying patients with ACD. Nevertheless, females should be additionally routinely tested with the fragrance series. Patients with suspected occupationally related dermatitis should always be tested with additional allergens and own products.

Exposure to hair dye is the most frequent route of sensitisation to para-phenylenediamine ( PPD), a common contact allergen. International studies have examined the profile of PPD, but Australian-sourced information is lacking. Patients are often dissatisfied with advice to stop dyeing their hair. This study examines patients' characteristics, patch test results and outcomes of PPD allergy from a single Australian centre, through a retrospective analysis of patch test data from 2006 to 2013 at the Liverpool Hospital Dermatology Department. It reviews the science of hair dye allergy, examines alternative hair dyes and investigates strategies for hair dyeing. Of 584 patients, 11 were allergic to PPD. Our PPD allergy prevalence rate of 2% is at the lower end of international reported rates. About half these patients also react to para-toluenediamine ( PTD). Affected patients experience a significant lifestyle disturbance. In all, 78% tried alternative hair dyes after the patch test diagnosis and more than half continued to dye their hair. Alternative non- PPD hair dyes are available but the marketplace can be confusing. Although some patients are able to tolerate alternative hair dyes, caution is needed as the risk of developing an allergy to other hair dye ingredients, especially PTD, is high.

BACKGROUND/OBJECTIVE Widespread dermatitis is often associated with diagnostic and therapeutic challenges. Multiple factors influence this widespread pattern of dermatitis. We aim to study the associated factors in patch-tested patients who presented with widespread pattern of dermatitis. METHOD This retrospective, case-control study was conducted on patients with dermatitis who were patch tested during January 2005 to December 2016. The demographic data, patient and family histories, diagnoses, and patch test findings were recorded and analyzed. RESULTS Of the 3201 included patients, 645 (20.2%) had widespread pattern of dermatitis. Being male, age >60, and history of either atopic dermatitis (AD) or metal allergy were significantly associated with the widespread dermatitis pattern. A multivariate analysis demonstrated that preservatives were the significant offending allergens, especially methylchloroisothiazolinone/methylisothiazolinone (MCI/MI), and methylisothiazolinone (MI) alone. CONCLUSION Widespread pattern of dermatitis is associated with gender, age, underlying atopic dermatitis and a history of metal allergy. Preservatives are the significant offending allergens of widespread dermatitis, especially MCI/MI, and MI alone. A thorough history taking and patch testing, including preservatives, are necessary to determine the cause of widespread pattern of dermatitis.

Background/Objectives Distinguishing between oral lichen planus (LP) and lichenoid reactions to dental restorations can be impossible on clinical and histopathological grounds. Epicutaneous patch testing is an investigation that may guide patients and physicians in making timely and costly decisions to replace or cover existing dental restorations. This study aimed to assess the role of epicutaneous patch testing with a battery of dental allergens in patients with undifferentiated oral LP. Methods A retrospective review of the medical records of patients with biopsy-proven oral LP referred by an oral medicine specialist and who presented for dental epicutaneous patch testing at a dermatology clinic in Perth, Western Australia between 2009 and 2016 was performed. Results In total, 68 patients were included, of whom 54 (79%) had positive patch tests. Gold 26 (48%), mercury 24 (44%), nickel 22 (41%), copper 19 (35%), potassium dichromate 14 (26%) and methylhydroquinone 13 (24%) were the most common allergens for which patients tested positive. Hypothyroidism and non-steroidal anti-inflammatory drugs were associated with negative patch tests (P = 0.01 and 0.04, respectively). Smoking history, other medications and comorbidities, the location of the dental restorations and unilateral or bilateral disease were not significantly associated with the patch test results. Restorations were removed in 23 patients: 21 of these (91%) had positive epicutaneous patch tests. Of the 20 patients followed up, 19 (95%) experienced some improvement, among whom 11 (58%) had complete remission. Conclusion Epicutaneous patch testing disclosed a high proportion of relevant positives. This guided the clinical decision to change dental restorations, with high rate of clinical improvement.

- Abstract
Allergic contact dermatitis is a disabling condition, significantly impacting on quality of life, which can only be alleviated by identification and avoidance of a relevant allergen. Patch testing remains the gold standard diagnostic test for allergic contact dermatitis. The consistency with which patch testing is used varies throughout the world. The purpose of this study was to look at the adequacy of current patch testing practice in New Zealand. We undertook literature review of current guidance regarding patch testing and created a web-based survey to evaluate use of patch testing in New Zealand. This was sent to all 75 vocationally registered New Zealand dermatologists. Of respondents, 46% do not perform patch testing. The most commonly cited barriers were lack of nursing support, poor remuneration, time pressure and lack of facilities. 23% noted that public patch testing services are not available in their region. The majority do not record patch test results in a database. Access to and utilisation of patch testing in New Zealand is suboptimal. Increasing services in the public sector requires investment by health boards, as there remains a dermatology workforce shortage in New Zealand. In private practice, patients often find it unsatisfactory to pay for negative tests, and adequate remuneration of patch testing by private insurers is necessary. Surveillance of patch test results at a national level is lacking, and the development of a centralised database to identify common allergens affecting our population is recommended., (© 2020 The Australasian College of Dermatologists.)

- Abstract
Background: Allergic contact dermatitis (ACD) is an increasingly common diagnosis in children. The objectives of this study were to review our experience with ACD in children in tertiary settings, to ascertain the spectrum of allergens in this population and to subsequently propose the first Australian Paediatric Baseline Series for patch testing., Methods: We conducted a retrospective analysis of patch test data from 1993 to 2017 from two tertiary referral patch-testing centres in Melbourne, Victoria., Results: A total of 511 children were patch tested during the study period. Of these, 58.3% (298/511) of children tested had a positive patch test, and 65.1% (194/298, or 38.0% of the total) had a relevant positive patch test. The most common relevant patch test reactions were fragrance mix, methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and methylisothiazolinone (MI), Myroxylon pereirae, nickel sulphate, and colophonium., Conclusion: Allergic contact dermatitis is not uncommon in children, and patch testing should be considered in children with suspected ACD or with recalcitrant atopic dermatitis. Based on our experience over 25 years, we propose the first Australian Paediatric Baseline Series., (© 2019 The Australasian College of Dermatologists.)

There are a number of reports in the literature of allergic contact dermatitis as a result of exposure to the sawdust and plant parts of Grevillea robusta. While this tree is prevalent in New Zealand, there seems to have been no previous published accounts of contact dermatitis, although anecdotal evidence indicates that such cases may be common. Two brief case reports are provided regarding severe phytodermatitis to G. robusta among professional arborists in New Zealand. As with other common plants capable of inducing allergic contact dermatitis, greater awareness among arborists, orchardists, forestry workers, gardeners, and health professionals will likely result in a reduction of cases.

A retrospective study was performed to analyse the clinical and photobiological features and therapeutic outcomes of 44 patients with chronic actinic dermatitis who were evaluated over an 8.3-year period. The study population comprised 37 men and seven women with a mean age of 62.7 years (range 26-85 years). The most common abnormal phototest results were decreased minimal erythema doses to both UVA and -B (73.8%), and to UVA alone (14.3%). Twenty-six patients (78.8%) had at least one allergic, photoallergic or combined allergic/photoallergic reaction. A total of 139 positive contact or photocontact reactions were recorded (mean 4.2 per patient). Most commonly, treatment consisted of photoprotection, topical corticosteroids and episodic use of systemic agents, in particular azathioprine.

A 39-year-old man presented with a 6-month history of a treatment-resistant facial dermatitis. The patient regularly used his mobile phone, predominantly on the left cheek. Patch testing confirmed the clinical suspicion of mobile phone contact dermatitis from nickel contained in the phone casing. Although infrequently reported, with the trend towards metallic mobile phone casings and the high incidence of nickel sensitization in the community, the incidence of mobile phone contact dermatitis is likely to increase.

Background/Objectives The aim of this study was to compare vasoconstrictor activity and, by inference, the clinical anti-inflammatory effectiveness of hydrocortisone in two different formulations: 1% dissolved hydrocortisone cream and 1% dispersed hydrocortisone cream. Moisturising capacity and safety were also determined. Methods Both topical preparations were applied without occlusion on forearms twice daily for 5 days. An assessment of vasoconstriction was performed in a double-blinded manner pretreatment and then thrice daily for 6 days and once 7 days post-application, using an objective rating scale. For the dissolved preparation only, moisturising capacity was determined by measurement of transepidermal water loss (TEWL) at 0, 2, 4, 6 and 24 h, and also by the measurement of water content at 0 and 24 h. Safety was assessed by repeat insult patch tests (RIPT). Results In all, 10 volunteers completed the vasoconstrictor and moisturising studies, while 52 completed the RIPT. For 1% dissolved hydrocortisone cream and 1% dispersed hydrocortisone cream, respectively, areas under the blanching curves were 1240 and 295; total scores were 129.0 and 31.5; summed % total possible scores were 161.3 and 39.4; Tm/10 mean values were 3.47 and 1.64. The 1% dissolved hydrocortisone cream was found to be statistically more potent than the 1% dispersed hydrocortisone cream. Furthermore, the 1% dissolved hydrocortisone cream was found to be moisturising compared to no treatment. No adverse events were observed. Conclusions A cream containing 1% dissolved hydrocortisone exhibits greater vasoconstrictor activity than a cream containing 1% dispersed hydrocortisone.

- Abstract
Background/objective: Widespread dermatitis is often associated with diagnostic and therapeutic challenges. Multiple factors influence this widespread pattern of dermatitis. We aim to study the associated factors in patch-tested patients who presented with widespread pattern of dermatitis., Method: This retrospective, case-control study was conducted on patients with dermatitis who were patch tested during January 2005 to December 2016. The demographic data, patient and family histories, diagnoses, and patch test findings were recorded and analyzed., Results: Of the 3201 included patients, 645 (20.2%) had widespread pattern of dermatitis. Being male, age >60, and history of either atopic dermatitis (AD) or metal allergy were significantly associated with the widespread dermatitis pattern. A multivariate analysis demonstrated that preservatives were the significant offending allergens, especially methylchloroisothiazolinone/methylisothiazolinone (MCI/MI), and methylisothiazolinone (MI) alone., Conclusion: Widespread pattern of dermatitis is associated with gender, age, underlying atopic dermatitis and a history of metal allergy. Preservatives are the significant offending allergens of widespread dermatitis, especially MCI/MI, and MI alone. A thorough history taking and patch testing, including preservatives, are necessary to determine the cause of widespread pattern of dermatitis., (© 2018 The Australasian College of Dermatologists.)

A 10-year-old girl presented with a 2-year history of severe cheilitis. Despite cessation of any lip-licking behaviour her symptoms continued to worsen, with only minimum relief from therapeutic measures. Patch testing proved strongly positive to cocamidopropyl betaine, which was noted to be present in the patient's '2-in-1 toothpaste and mouthwash'. Her cheilitis settled after avoidance of this product. Cocamidopropyl betaine, a surfactant, is a common allergen in hairdressers; however, this case highlights the importance of excluding a contact allergy to this product in patients with intractable cheilitis.

We report on our experience with sunscreen allergy between 1992 and 1999 and also review the international literature on sunscreen allergy. There were a total of 21 allergic reactions to sunscreen chemicals observed in 19 patients over the 8 years. There were nine positive photopatch reactions to oxybenzone, eight to butyl methoxy dibenzoylmethane, three to methoxycinnamate and one to benzophenone. No positive reactions were observed to para aminobenzoic acid. Six patients also had positive patch tests to components of the sunscreen base. In our experience, sunscreen chemicals are the most common cause of photoallergic contact dermatitis.

Printers are exposed to a wide variety of irritants and sensitizers. Allergy developing from a single exposure to any compound is rare. We report two cases of workers in the printing industry who developed allergic contact dermatitis to 1,6-hexanediol diacrylate (HDDA) within a short period of exposure. The first developed within weeks of exposure to a plastic sheet primed with HDDA. The second developed after a single accidental exposure.

Sunscreen reactions are said not to be uncommon. A population referred to a patch testing clinic was evaluated for reactions to sunscreen by questionnaire initially and then, if relevant, by patch testing to sunscreen products and their components. Irritant reactions were more common than allergic contact dermatitis. Allergic reactions to sunscreens were less common than to non-sunscreen chemicals present in sunscreen products.

- Abstract
Background/objectives: Distinguishing between oral lichen planus (LP) and lichenoid reactions to dental restorations can be impossible on clinical and histopathological grounds. Epicutaneous patch testing is an investigation that may guide patients and physicians in making timely and costly decisions to replace or cover existing dental restorations. This study aimed to assess the role of epicutaneous patch testing with a battery of dental allergens in patients with undifferentiated oral LP., Methods: A retrospective review of the medical records of patients with biopsy-proven oral LP referred by an oral medicine specialist and who presented for dental epicutaneous patch testing at a dermatology clinic in Perth, Western Australia between 2009 and 2016 was performed., Results: In total, 68 patients were included, of whom 54 (79%) had positive patch tests. Gold 26 (48%), mercury 24 (44%), nickel 22 (41%), copper 19 (35%), potassium dichromate 14 (26%) and methylhydroquinone 13 (24%) were the most common allergens for which patients tested positive. Hypothyroidism and non-steroidal anti-inflammatory drugs were associated with negative patch tests (P = 0.01 and 0.04, respectively). Smoking history, other medications and comorbidities, the location of the dental restorations and unilateral or bilateral disease were not significantly associated with the patch test results. Restorations were removed in 23 patients: 21 of these (91%) had positive epicutaneous patch tests. Of the 20 patients followed up, 19 (95%) experienced some improvement, among whom 11 (58%) had complete remission., Conclusion: Epicutaneous patch testing disclosed a high proportion of relevant positives. This guided the clinical decision to change dental restorations, with high rate of clinical improvement., (© 2017 The Australasian College of Dermatologists.)

A 37-year-old meat inspector presented with a 5-month history of forearm eczema. His symptoms improved at weekends and over holidays but flared within a day of work. Scratch patch tests were strongly positive to fresh venison diaphragm and venison liver and weakly positive to venison hide and blood, and lamb blood. They were negative to other venison and lamb components. Type IV allergy tests with Standard European and fragrance batteries were negative. The eczema cleared with a change in work role, clobetasol-17-propionate cream, flucloxacillin and aqueous cream. He was then able to return to meat inspecting. Provided he was diligent about applying 'Dermashield' barrier foam and minimizing contact with irritants, his eczema has remained well controlled over the last 4 years. Attention to irritant contact dermatitis is important in the management of protein contact urticaria.

A 40-year-old male developed a constant hand and foot dermatitis in 1980 while using sorbolene cream as a barrier cream at work. He was forced to leave his trade as a motor mechanic because of his hand dermatitis. It was not until 16 years later that he was diagnosed as having an allergic contact dermatitis to chlorocresol secondary to an endogenous hand and foot dermatitis. Chlorocresol is the preservative used in sorbolene cream as well as many corticosteroid creams. Patch testing carried out in 1983 was negative but had omitted testing with chlorocresol or sorbolene cream.
