Abstract
Eyelid and periorbital dermatitis remains a distressing and recalcitrant disease. Contact dermatitis remains the most common cause of eyelid and periorbital dermatitis. Ophthalmic solutions used in the treatment of ophthalmic conditions can often be the cause. This article is an update of our previous study, summarizing the contact allergens involved and the new test concentrations reported to investigate through patch testing. New insights found during the review are also documented.

Abstract
Background/Objectives: Paraphenylenediamine (PPD) is an aromatic amine dye that may cause allergic contact dermatitis. This study examines the epidemiology of allergic patch test reactions to PPD. Methods: This retrospective analysis characterizes individuals tested to PPD (1% petrolatum) by the North American Contact Dermatitis Group (1994-2018). Demographics and dermatitis site(s) were compared between PPD-allergic and PPD-negative patients. PPD reactions were analyzed by reaction strength, clinical relevance, occupational relatedness, and source as well as coreactivity with structurally related compounds. Results: Of 54,917 patients tested to PPD, 3095 (5.6%) had an allergic patch test reaction. Compared with PPD-negative patients, PPD-allergic patients had significantly greater odds of age >40 years (odds ratio [OR] 1.55 [95% confidence interval; CI 1.43-1.69]) and female gender (OR 1.52 [95% CI 1.41-1.66]), but lower odds of being White (OR 0.66 [95% CI 0.60-0.71]). The most common primary anatomic sites of dermatitis were face (25.5%), hands (21.9%), and scattered/generalized pattern (15.5%). Over half (55.3%) of PPD reactions were ++ or +++ at the final reading and 60.9% were currently relevant. Common exposure sources included hair dye (73.5%) and clothing/shoes/apparel (3.9%). Occupationally related reactions occurred in 8.3%, most commonly in hairdressers/cosmetologists (72.8%). The most common coreactions were benzocaine (11.3%), N-isopropyl-N'-phenyl-p-phenylenediamine (6.7%), disperse dye mix (6.5%), and black rubber mix (5.1%). Conclusions: The 24-year percentage of allergic reactions to PPD was 5.6%. PPD allergy was associated with female gender and age >40 years. PPD allergic patients were less likely to be White. Allergic reactions were usually clinically relevant and hair dye was the most frequently identified source.

Abstract
INTRODUCTION Nickel is a principal alloying agent in the production of vascular endoprostheses, despite persisting as the most habitually identified allergen. Variable nickel-related hypersensitivity manifestations following endovascular intervention were reported, challenging established paradigms in treatment and accuracy of prognostic assessments. The objective of this review is to critically evaluate current metrics to maximise patient-related outcomes. METHODS A literature review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 statement. Patients indicative of nickel hypersensitivity reaction following endovascular intervention were discerned. A positive reaction was defined by patch testing, histological analysis, or anamnesis indicative of nickel hypersensitivity. Morphology of implicating prostheses, adverse events and postoperative complications, clinical course, diagnostic and therapeutic strategies alongside patient prognosis were recorded. RESULTS Nickel-related hypersensitivity reactions following endovascular repair were identified in 36 patients with a median age of 44.5 years. 20 patients received nitinol-containing intervention. 28 (77.8%) patients are female. Multi-organ adverse reactions occurred in 21 (58.3%) patients with variable latency. 14 (38.9%) patients were presented with neurological adverse reactions manifesting mainly as unilateral hemiparesis. Dermatological reactions implicated 16 (44.4%) patients. Miscellaneous manifestations include suicidal ideation. 13 (36.1%) patients displayed previous metal intolerance and 32 (88.9%) patients had positive patch testing for nickel. Histological analysis of lesions and prostheses indicated lymphocytic infiltration. 5 (13.9%) patients experienced device-specific reactions as in-stent restenosis or auxiliary distal vessel stenosis. 11 (30.1%) patients received solely medical therapy and 5 (13.9%) patients received solely surgical therapy. 19 (52.7%) patients underwent both medical (oral corticosteroid) and surgical therapy (device retrieval). 26 (77.1%) patients achieved symptomatic cessation, 6 (16.7%) patients exhibited symptomatic persistence and 0 patients died. CONCLUSION Prophylactic pre-assessment for a history of metal allergy and consideration of prostheses alternatives is recommended to minimise reaction risk and severity. Despite nickel's predominant usage, information paucity urges additional studies to emphasise its implications and maximise patient outcomes.

Abstract
BACKGROUND A popular antiseptic spray in Switzerland (Merfen spray), containing chlorhexidine digluconate, benzoxonium chloride and lauramine oxide, is frequently used to treat skin wounds. However, it is also increasingly reported as a major cause of adverse skin reactions, including allergic contact dermatitis (ACD). OBJECTIVES To investigate the contact allergens responsible for ACD from this antiseptic. PATIENTS/METHODS Patch tests were performed on seven patients with a clinical history compatible with contact dermatitis from this antiseptic mixture. RESULTS All patients presented with acute eczematous reactions following contact with either Merfen spray alone, or with multiple products including this spray. Patients showed positive reactions to this product in both patch tests and repeated open application tests (ROATs). Four patients showed dose-dependent reactions to both benzoxonium chloride and lauramine oxide. One patient showed a dose-dependent reaction to the former and a non-dose-dependent reaction to the latter. Finally, two subjects showed responses only to lauramine oxide. One patient reacted to chlorhexidine digluconate 0.5% aq. in addition to both other allergens. CONCLUSIONS Two commercially unavailable allergens, that is, benzoxonium chloride and/or lauramine oxide were identified as major causes of ACD from Merfen antiseptic spray, whereas chlorhexidine digluconate was a contributing culprit in only one patient.

Abstract
The "Atopy Patch Test" (APT) has been proposed as a diagnostic tool for food allergies (FA), especially in children with FA-related gastrointestinal symptoms. However, its diagnostic accuracy is debated, and its usefulness is controversial. The aim of this systematic review was to evaluate the APT diagnostic accuracy compared with the diagnostic gold standard, i.e., the oral food challenge (OFC), in children affected by non-IgE mediated gastrointestinal food allergies, including the evaluation in milk allergic subgroup. Both classical non-IgE mediated clinical pictures and food induced motility disorders (FPIMD) were considered. The search was conducted in PubMed and Scopus from January 2000 to June 2022 by two independent researchers. The patient, intervention, comparators, outcome, and study design approach (PICOS) format was used for developing key questions, to address the APT diagnostic accuracy compared with the oral food challenge (OFC). The quality of the studies was assessed by the QUADAS-2 system. The meta-analysis was performed to calculate the pooled sensitivity, specificity, DOR (diagnostic odds ratio), PLR (positive likelihood ratio), and NLR (negative likelihood ratio) with their 95% confidence intervals (CI). Out of the 457 citations initially identified via the search (196 on PubMed and 261 on Scopus), 37 advanced to full-text screening, and 16 studies were identified to be included in the systematic review. Reference lists from relevant retrievals were searched, and one additional article was added. Finally, 17 studies were included in the systematic review. The analysis showed that APT has a high specificity of 94% (95%CI: 0.88-0.97) in the group of patients affected by FPIMD. Data showed a high pooled specificity of 96% (95% CI: 0.89-0.98) and the highest accuracy of APT in patients affected by cow's milk allergy (AUC = 0.93). Conclusion: APT is effective in identifying causative food in children with food-induced motility disorders. What is Known: • Atopy patch test could be a useful diagnostic test for diagnosing food allergy, especially in children with food allergy-related gastrointestinal symptoms. What is New: • Atopy patch test may be a useful tool in diagnosing non IgE food allergy, especially in children with food-induced gastrointestinal motility disorders and cow's milk allergy.

Abstract
Eyelid dermatitis may present with a variety of clinical findings including erythema, pruritus, and edema, and it has a wide differential. Allergic contact dermatitis due to allergen sources in personal care products, cosmetics, and fragrances is a leading cause of eyelid dermatitis and may be challenging to diagnose by clinical examination alone. Expanded patch testing, in addition to careful inspection of the surrounding skin for additional areas of involvement and clinical clues, remains an important tool in differentiating allergic contact dermatitis from other relevant etiologies of eyelid dermatitis including irritant contact dermatitis, atopic dermatitis, seborrheic dermatitis, and rosacea. We present a practical approach to the management of eyelid dermatitis including the use of a topical anti-inflammatory for long-term control of eyelid findings. Further diagnostic workup may be warranted in patients with refractory eyelid dermatitis.

Abstract
PURPOSE A review of the published literature on the pathogenesis and treatment of eyelid allergic contact dermatitis and ocular surface involvement. METHODS Literature search of MEDLINE (Ovid) was conducted using for allergic contact dermatitis and disease of the eyelid or periorbital skin. Dates included in search criteria were from January 1, 2010 to January 12, 2023. 120 articles were reviewed by at least two authors. RESULTS Allergic eyelid contact dermatitis(ACD) is a Type IV hypersensitivity reaction to chemical exposure of sensitized eyelid skin. Most patients improve with avoidance strategies. Understanding chemicals that may trigger eyelid ACD, identifying allergens with patch testing, and use of topical steroids can help patients with this challenging disease. CONCLUSIONS Recalcitrant allergic eyelid dermatitis can be addressed by an interdisciplinary team and avoidance strategies based on patch testing.

Abstract
Atopic dermatitis is a chronic inflammatory disease that is multifactorial in nature. Allergic contact dermatitis and protein contact dermatitis are allergic conditions that may occur in the context of atopic dermatitis and be the cause of exacerbations. Although the prevalence of allergic contact dermatitis is similar in atopic patients and the general population, these 2 conditions are frequently associated because atopic inflammation disrupts the skin barrier. Skin tests are therefore recommended in atopic individuals. Dupilumab could be useful for treating allergic contact dermatitis if it is mediated by type 2 helper T cells but could exacerbate inflammation if mediated by TH1 cells: further study is needed before conclusions can be drawn. Although the mechanism by which exposure to environmental proteins exacerbates atopic dermatitis remains under discussion, such exacerbations are routinely seen in clinical practice. Prick testing is recommended in symptomatic atopic dermatitis. When prick-test findings are positive, patients should be advised to avoid the culprit substances.

Abstract
Cocamidopropyl betaine (CAPB) is an amphoteric surfactant. It has several functions, including producing effervescence and washing effects, and thus, it is used in many cleansing products, such as shampoo and liquid body cleansers. Recently, it has become clear that some impurities that arise during the manufacturing process can have sensitizing effects. Herein, we report a case of allergic contact dermatitis caused by detergents containing CAPB, in which an impurity was determined to be the possible causative agent by patch testing and chemical analysis.A 64-year-old Japanese female developed a skin rash on the hairlines of her forehead and nuchal region one month before her first visit to our clinic. Later, the rashes, which were composed of desquamative erythema, expanded to her face, neck, upper back, and chest. Patch tests produced positive results for a shampoo and liquid body cleanser (1% aq.) that she had used as well as for CAPB (1% aq.); lauramidopropyl betaine (LAPB) (1% aq.); and lauramidopropyl dimethylamine (LAPDMA) (0.05% aq.), which is an impurity of CAPB. The rashes resolved completely after we instructed her to use products without CAPB and LAPB. When issuing such instructions, clinicians should have correct knowledge about surfactants, such as the differences between cosmetic ingredient names and quasi-drug ingredient names.

Abstract
BACKGROUND Ten percent efinaconazole nail solution (EFCZ solution) is a new topical triazole antifungal drug, and we sometimes encounter patients with allergic contact dermatitis (ACD) caused by EFCZ solution in our outpatient clinic. However, no previous reports have summarized the patch test (PT) results obtained for individual ingredients in several patients with EFCZ solution-induced ACD. OBJECTIVES This study aimed to 1) confirm the causative agent of EFCZ solution-induced ACD based on PT of individual ingredients and 2) analyze the optimal concentration and vehicle for such PT on the basis of previous studies. PATIENTS AND METHODS We clinically diagnosed eight patients with EFCZ solution-induced ACD from Sep. 2014 to Aug. 2021, and performed 48-hour closed PT using EFCZ solution and its ingredients. Readings were done on days (D) 2, 3, and 7 according to the International Contact Dermatitis Research Group criteria. RESULTS Six of the 8 patients underwent PT with EFCZ solution, and all showed + to +++ reactions on D3. The results for the main component, EFCZ, were + to +++ on D3 in all patients. Two patients were patch tested with both 10% EFCZ in ethanol and 10% EFCZ in petrolatum, which produced similar reactions. One patient had an allergic reaction to ethanol. CONCLUSIONS The causative agent of EFCZ solution-induced ACD was EFCZ in all patients. For PT, we recommend EFCZ solution as is, its 10-fold dilution and 1% and 0.1% EFCZ in petrolatum.

Abstract
Purpose of Review This article aims to summarize some recent trends in occupational allergic contact dermatitis (ACD), including dermatitis related to pandemic-level personal protective equipment in healthcare workers, hazards patients may experience when working from home, and occupational perspectives on the recent American Contact Dermatitis Society (ACDS) allergens of the year and ACDS Core Allergen Series updates. Recent Findings Recent ACDS Allergens of the Year may be particularly relevant to healthcare workers, including isobornyl acrylate, which is present in glucose sensors and propylene glycol present in hand cleansers and disinfectants. Lavender, limonene, and linalool, all of which are new additions to the ACDS Core Allergen Series, have been reported as causes for occupational ACD in massage therapists and aromatherapists. Isothiazolinone allergy continues to rise in both consumer and occupational settings. Finally, the COVID-19 pandemic has resulted in a wave of occupational ACD in healthcare workers to personal protective equipment, and revealed new potential allergens for individuals working from home. Summary Occupational allergic contact dermatitis continues to exert a significant occupational disease burden. Remaining aware of the current trends in allergens may allow for earlier recognition, diagnosis, and treatment, subsequently helping our patients to work in healthier and safer environments.

Abstract
Long-lasting allergic patch test reactions (LLAPTR) are those in which the clinical features of palpable erythema are still present at the site of a positive allergic patch test reaction 14 or more days after application of the allergen. LLAPTR have been described for a wide range of contact allergens, many of these included in the baseline patch test series. LLAPTR are far from uncommon; they occur in consecutive patients with positive patch tests to baseline allergens with frequency up to 17.9% of the total reactions. Patch test reactions persisting for a very long time (up to several months after the test) have been described, the most frequent ones being those induced by gold salts. The pathomechanisms of LLAPTR have not been clarified, but may hypothetically involve a constant antigen stimulation and/or a defect in cell-mediated immunity down-regulation. Host-related factors significantly associated with LLAPTR are, according to some studies, a strong initial patch test response, older age, and atopy. No significant sex differences have been observed in the frequency of LLAPTR.

Abstract
Basal cell carcinoma is the most common epithelial skin cancer in humans and usually effects elderly individuals. Although the pathogenesis is directly related to exposure to ultraviolet sunlight, other factors,particularly trauma, may be involved. We present the case of a woman with contact dermatitis due to sensitization to metals. She developed superficial basal cell carcinoma at the same site as a patch test-performed 30 months earlier-that was strongly positive to 1 % gold chloride. In the histologic study with a scanning electron microscope, we detected electron-dense particles in the dermis which were subsequently identified as gold.

Abstract
"Recall dermatitis" classically refers to the uncommon phenomenon of chemotherapy-induced reactivation of skin damage originally induced by radiotherapy months or years earlier. We compare this condition to ectopic flare-up reactions presenting as dermatitis at existing or previous sites by an inducing agent. Enhanced sensitization of an existent allergen by patch testing is rarely described. We describe a case of a 61-year-old man's developing localized allergic contact dermatitis at previous neomycin-treated sites following the diagnosis of neomycin sensitivity on patch testing, which we attribute to a "flare-up" phenomenon.

Abstract
Para-phenylenediamine (PPD), a constituent of permanent hair dyes, may cause contact allergy in exposed individuals. It has previously been questioned whether a patch testing with PPD in population-based epidemiological studies is entirely safe. The Glostrup allergy studies patch tested the same cohort twice. In 1990, 567 persons were patch-tested and only one person had a (+) positive reaction to PPD. In 1998, 540 persons were re-invited to a new patch test and 365 (participation rate 68%) were re-tested. There were no positive reactions to PPD. These studies indicate that patch testing with PPD in individuals with no previous positive reactions to PPD or with only one previous positive reaction does not cause active sensitization and can be performed with minimal risk.

Abstract
Evidence regarding the risk of active sensitization (AS) to p-phenylenediamine (PPD), patch tested 1% in petrolatum, is conflicting. The objective of this study was to evaluate the relative frequency of 'environmental' exposures and skin reactions to products potentially containing PPD in subgroups of patients with versus without newly diagnosed contact allergy (CA) to PPD upon retesting. Patients patch tested twice with PPD between 1996 and 2004 in the Information Network of Departments of Dermatology (IVDK) network were identified and classified into 4 groups, according to the 2 test results with PPD at D3. A self-administered questionnaire was mailed to 171 patients (response 57%). The frequency of exposure to 'henna tattoos', dark hair dyes, or textiles or work as hairdresser did not differ significantly between the groups. A significantly shorter median interval between the 2 patch tests was observed in the group with newly diagnosed PPD CA compared with the other groups (293 versus >700 days). The results of the study add new, if somewhat weak, evidence to the notion that patch testing with PPD may indeed carry some risk of AS, as environmental exposures to PPD were as common in the subgroup of patients with incident CA to PPD as in the remaining patients.

Abstract
Several studies have evaluated patch testing for the diagnosis of drug eruptions, but widespread acceptance of this procedure is lacking in North America. The objective of this review is to address patch testing for the evaluation of exanthematous drug eruptions due to systemic antibiotics, using a MEDLINE database search for articles in English on patch testing for systemic drug eruptions caused by antibiotics.

Abstract
Uncommon adverse reactions to patch testing have been reported, but few cases have shown patch testing to be a potential contraindication. We report a patient with known pemphigus foliaceus who had significant epidermal detachment of normal skin during the removal of patch-testing tape.
