Objective: To analyse the clinical characteristics and sensitivity of an essential oil patch test series (EOS) in patients sensitized to their own essential oils (EOs). Method: We analysed the clinical data and patch test results obtained with the European baseline series (BSE) and an EOS, as well as the mode of use of EOs, through a questionnaire included in the patient file. Results: The study included 42 patients (79% women, average age 50 years) with allergic contact dermatitis (ACD), 8 patients required hospitalization. All patients were sensitized to the EO they used, primarily lavender (Lavandula augustifolia, 8000‐28‐0), tea tree (Melaleuca alternifolia leaf oil, 68647‐73‐4), ravintsara (Cinnamomum camphora oil, 92201‐50‐8), and 2 cases were attributed to helichrysum (helichrysum italicum flower absolute, 90045‐56‐0). 71% had positive patch tests to fragrance mix I or II, 9 only to the EOS and 4 only with their personal EO. Interestingly, 40% of patients did not spontaneously mention the use of EOs, and only 33% received advice on their use at the time of purchase. Conclusion: Patch tests with the BSE, limonene and linalool HP, and oxidized tea tree oil is sufficient to detect most EO‐sensitized patients. The most important is to test the patient's own used EOs. [ABSTRACT FROM AUTHOR]

This article discusses a case of occupational contact dermatitis in a 44-year-old man who developed a recurrent facial rash after exposure to pyrethrum daisies (Tanacetum cinerariifolium) at his workplace. The man experienced symptoms for 2-4 weeks each summer, which improved but did not completely resolve after 2 months. Patch testing revealed positive reactions to the crop, as well as other substances. The patient was prescribed medication and provided with protective equipment to wear during exposure. The article emphasizes the importance of patch testing for specific allergens to which a patient may be exposed, rather than relying solely on commonly tested allergens. [Extracted from the article]

Objective: The aim of this study was to identify which types of skin reactions are associated with slime toys and which of their ingredients are most frequently involved in cases of poisoning. Data source: Between January and July 2021, articles were selected using PubMed, SciELO, and LILACS databases. The following descriptors were used: (dermatitis OR rash OR eczema OR inflammation) AND slime. Inclusion criteria were articles available in full, in either Portuguese, English, or Spanish, published between January 2000 and July 31, 2021, and articles reporting cases of contact dermatitis or eczema potentially or directly attributed to slime toys. Articles not meeting these criteria and duplicate texts in the databases were excluded. Data synthesis: In total, 65 publications were identified, of which 16 were included in this review. This resulted in a total of 22 children (2 males, 20 females), aged between 4 and 13 years, who were reportedly intoxicated by slime toys, most of these being linked to homemade preparations. Studies reported the occurrence of contact or allergic dermatitis on hands, fingers, nails, forearms, and cheeks. The most allergenic and/or irritant ingredients included liquid detergent and soap. Additionally, patch tests identified positive reactions to methylisothiazolinone and methylchloroisothiazolinone, the preservatives used by chemical industries on preparation of glue, soap, detergents, etc. Conclusions: Although slime toys might be important for improving motor development and parental relationships, homemade slime toy recipes include several allergenic and irritant ingredients which might be exposed to vulnerable children and cause intoxications. Therefore, homemade slime toys preparations should be used cautiously and under the supervision of adults. [ABSTRACT FROM AUTHOR]

Contact allergy to skin disinfectants is not often recognized in children. We report the cases of six children (1–16.5 years old) with allergic contact dermatitis to ingredients commonly contained in commercial antiseptic and cosmetic products. Patch test responses to chlorhexidine, benzyl alcohol, and benzalkonium chloride varied from one child to another one, but most children were sensitized to at least two components. In several of the cases, exposure had initially occurred in the neonatal period, but diagnosis occurred only after multiple reactions of increasing severity. [ABSTRACT FROM AUTHOR]

CHEILITIS , *PROPOLIS , *ECZEMA , *IMMUNITY , *COVID-19 pandemic - Abstract
Propolis is a lipophilic resin extracted from plants by bees. The purpose of this case report was to show the importance of this substance as cause of allergic contact cheilitis. A 21-year-old female patient complained of pruritic perioral eczema for 5 years. In the past months it also affected the neck. After diagnosing contact dermatitis, she was submitted to a patch test with a Latin American baseline series. The result was strongly positive for propolis (++) and weakly positive for perfume mix I (+). After the test, the patient revealed she had been using propolis drops, per oris, for 10 years. The worsening of the condition was due to increased dose, aiming "to improve immunity", during the coronavirus disease 2019 (COVID-19) pandemic. The contact allergy to propolis might be increasing due to the widespread use of natural products. Propolis is a sensitizer to be considered in patients with long-lasting cheilitis.

CROSS-sectional method , *ECZEMA , *ALLERGENS , *CONTACT dermatitis - Abstract
Background: Methyldibromo glutaronitrile (MDBGN) was one of the most frequent and relevant allergens found in patch testing at the beginning of this century. In 2008, this preservative was banned from cosmetics in Europe and ever since the prevalence of contact allergy to MDBGN has progressively decreased. Despite that gradual decline, MDBGN is still patch‐tested in most baseline series. This study assessed the frequency of MDBGN sensitization, epidemiological characteristics of allergic patients, and the relevance of positive patch tests in a nationwide Spanish registry (REIDAC). Patients and methods: We evaluated consecutively patch‐tested patients in all participating centres. Using these data, we calculated the proportion of patients with positive patch tests to MDBGN from June 2018 to June 2020 and evaluated the relevance of the positive patch tests. Results: One hundred and fourteen out of 5072 (2.24 %) tested patients were sensitized to MDBGN. Clinical current relevance was confirmed in only one case. Conclusion: Although the frequency of contact allergy to MDBGN remains high, no clinical significance was found in most of these patients (5072 tests needed to obtain one relevant positive result). The clinical usefulness of this allergen seems weak and its continued inclusion in the European baseline series is questionable. [ABSTRACT FROM AUTHOR]

PHENYLENEDIAMINES , *CONTACT dermatitis , *ECZEMA , *HAIR dyeing & bleaching , *ALLERGIES , *ALLERGENS - Abstract
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.

Palmoplantar pustulosis (PPP) is a chronic and relapsing disease of the palms and soles, which tends to be difficult to treat. Classically it was described as a subtype of psoriasis. Nowadays it is regarded as a separate entity, although plaque-type psoriasis affects concomitantly many patients with PPP. A link between allergic contact dermatitis (ACD) and PPP has been described, and the former may encompass a potential to perpetuate the latter. Hereby we report two cases of difficult to treat plantar pustulosis. Underneath the dermatosis's refractive nature was an allergic sensitization to potassium dichromate and cobalt chloride. Leather shoes and leather insoles were commonly worn, and both allergens are employed by the leather industry. Clinical remission was achieved in both cases with allergen eviction. Patch testing must be considered in cases of PPP without response to treatment. If relevant sensitization is found, allergen eviction measures are mandatory. [ABSTRACT FROM AUTHOR]

Of 7887 patients with eczema seen in a private dermatological practice over a period of 2 years and 4 month a specific final diagnosis was found in 5376 (68%), while a final diagnosis of non-specific eczema was made in 2511 cases (32%) The most common final diagnoses were seborrhoeic dermatitis (1351) contact dermatitis (1317), atopic dermatitis (1009) and nummular eczema (822). Battery patch testing was the initial diagnostic procedure performed, and 897 of the 3164 patients who were patch tested had one or more positive patch tests. In 545 cases, the reactions were considered of relevance to the current dermatitis. Tests for immediate-type allergy were carried out in 618 patients, and 284 of these had once or more positive tests. In 86 patients,these test results were of diagnostic significance 257 patients with positive patch tests were challenged orally with the relevant substance , and 53 of 156 reacted to metal salts, most commonly nickel, while 25 of 101 reacted to orally ingested balsam of Peru. Among patch-test-negative patients, 66 of 408 had positive reactions to one or more metal salts; 41 of 180 reacted to balsam of Peru, while 15 of 41 reacted to various food additives.

Hospital cleaning personnel were examined For occupational dermatoses. 356 persons were included in the study. The age ranged from 20 to 63 years with a mean of 40.1 years. The period prevalence rate of moderate and severe eczema was 12% (10% in men and 19% in women). In 88% the eczema was of a duration longer than 2 years. Positive patch tests were found in 10% of men and 53% of women with eczema. The main allergens were nickel, cobalt, chromate and rubber chemicals. Positive tests to cleaning agents were rare. One case of contact allergy to sodium dichloro-iso-cyanurate and one to lysol were diagnosed. Irritant factors played a major role in most cases (92%). Fungus infection as a cause or complication in hand eczema should not be left out of consideration: in 2 persons, a mycosis of hands and/or fingernail was diagnosed. [ABSTRACT FROM AUTHOR]

Nickel is the most important sensitizer in Lagos, with an incidence of 12.3% of 453 patients tested. There was no sex difference, as the wearing of necklaces and bracelets was equally fashionable among both sexes. Housewife eczema is not common, probably because of hardening. Dermatitis from additives in the processing of leather and rubber footwear was the next most common. Chromate sensitivity comes usually from leather or cement. Cultural and climatic factors are mainly responsible for differences in the incidence of contact dermatitis found in Lagos from other countries. [ABSTRACT FROM AUTHOR]

A total of 1652 consecutive patients with dermatitis were tested. The usefulness of this patch test battery was limited. There was a few positive reaction to Cytox 3522® , BIT and the 2-formaldehyde releaser, Preventol D2® and Grotan BK®. These reactions could not however, be explained. The MOAHL-index (% of Male patients from the 6 clinics showed equal frequencies of male patients and atopics, but significant differences in the frequencies of occupational cases, hand eczema, and leg ulcer/ stasis dermatitis, indicating possible variations in referral patterns, use of patch tests, and / or environmental factors.

Forty-eight patients with a positive patch test to potassium dichromate 0.5 % were retested after 4-7 years; 38 patients (79 %) still had a positive patch test. Chromate allergy seems to be persistent. In 72 % of the cases a history of occupational exposure to chromates could be proved. [ABSTRACT FROM AUTHOR]

A group of 36 normal control persons was patch-tested with glass fibers. The tested filaments had a length of about 3 to 5 mm and a diameter of 9 to 13 µm. The glass fibers were obtained from the normal production process. They were coated with cured epoxy resin. A group of 29 normal control persons was tested with the same type of fibers from which the epoxy finish had been burned off. Another group of 36 persons was patch-tested with ultrasmall glass globes with a diameter of 10 to 15 µm. Coated and uncoated glass globules were tested. On every person 5 patch tests with the same material were done. They were removed after 1, 5, 24, 48 and 72 h. On coated fiber, 12 of 36 tested people reacted with either a + or a ++ reaction. On the uncoated fibers a reaction could be noted in 10 out of 29 persons. The patch tests with coated as well as uncoated glass globules were all negative. A total of 60 biopsies was performed In those cases where + or ++ reactions were noted. The histological examination of the biopsies showed no differences between the reactions on coated and uncoated fibers. The skin reactions to glass fiber showed, besides microtraumatic changes, several histological characteristics of an eczematous reaction, like spongiosis and perivascular lymphocytic infiltration. The importance of these findings is discussed. It is emphasized that histological alterations are only one of the six points which must be taken into account when the diagnosis of eczema is considered. [ABSTRACT FROM AUTHOR]

We have studied a group of 104 patients with pompholyx. to investigate the relationship between allergotogical factors and its etiopathogenesis, The following examinations were performed, blood sampling routine tests and IgE levels. allergological tests (patch, prick. intradennal. and oral renovation tests with nickel sulphate), skin biopsy to exclude pemphigus vulgarism or bullous pemphigoid. An accurate history of familial and personal allergic diathesis was enquired for and various possible aggravating factors (season. microclimate, perspiration and emotional stress) were considered. The results were age `and sex-matched with a healthy control group (208 Subjects). We found familial and personal atopic diathesis in 50% of patients versus 11.5% of controls (P < 0.001); 39 positivity on patch testing 20.19% versus 6.25% of the control group (P<0.001) the % of Patients allergic to nicked reached 26% meluding those (6 Patients) reacting to the oral propagation test season 143 patients) and hyperhidrosis (38) were the aggravating factors most commonly claimed. We detected no correlation between age, sex, grading of pompholyx, and the allergological parameters investigated. Though several different allergological findings have previously been reported indydhidroiss their role in its pathogenses has not yet been fully explained. We think that different haptens or antigens can produce the same clinical and histological picture of pompholyx in predisposed subjects [ABSTRACT FROM AUTHOR]

Delayed reactions to phenylephrine, used as a mydriatic agent during ophthalmological surgical procedures, are well known. We diagnosed a delayed hypersensitivity reaction to phenylephrine included in an ophthalmic insert in a woman presenting, 24 h after surgery, with an acute blepharoconjunctivitis associated with eyelid eczema of the operated eye. The diagnosis was supported by the recognition of clinical symptoms associated with a positive patch test to phenylephrine. Patients who present with previous contact eczema to phenylephrine may develop a generalized eczema if phenylephrine is injected intravenously. Intravenous phenylephrine is increasingly being used in the operating room to treat hypotension. This case report confirms the need for systematic allergological investigation of all drugs and substances administered during the peri-operative period in order to avoid a delayed hypersensitivity reaction occurring after the peri-operative period. Anaesthetists should be aware of the possibility of delayed hypersensitivity reactions involving phenylephrine. [ABSTRACT FROM AUTHOR]

High frequencies of contact allergy to fragrance ingredients have been reported in recent years. Only approximately 70–80% are detected by fragrance allergens in the standard patch test series. This investigation compares the patch test reactions to fine fragrances with reactions to fragrance mix (FM), balsam of Peru (BP) ( Myroxylon pereirae resin) and a fragrance series. 641 consecutive patients with eczema were patch tested with the European standard series and with selected fine fragrances. Those who were positive to 1 of the fine fragrances or the FM or BP were also tested with the fragrance series. 95 (14.8%) patients were found to have a positive patch test reaction to FM or BP; 41 (6.4%) had positive results to fragrance no. 1 and 29 (4.5%) to no. 2. 9 (9.5% of the 95 positive patients) had a positive reaction to fine fragrances and a negative reaction to all other fragrance allergens in the standard series. These findings indicate that testing with fine fragrances can add to our evaluation of fragrance-sensitive patients. [ABSTRACT FROM AUTHOR]
