Contact Dermatitis

BACKGROUND: Professional cleaners are commonly affected by hand eczema (HE) due to wet work and exposure to cleaning products in the work environment. OBJECTIVE: To investigate (1) the prevalence of HE in a group of professional hospital cleaners, (2) the association of HE with various comorbidities and self-reported signs/symptoms of skin lesions and (3) the association of HE with various occupational and personal risk factors in the same population. METHODS: A cross-sectional questionnaire-based study including all cleaners working in three hospitals in Denmark...

BACKGROUND: Professions requiring frequent and/or long lasting wet-work are at high risk for contact dermatitis (CD). CD may lead to loss of work productivity, sick leave and reduced quality of work. The 1-year prevalence of healthcare workers varies between 12% and 65%. However, the prevalence of CD among surgical assistants, anaesthesia assistants and anaesthesiologists is unknown. OBJECTIVES: (1) To establish the point-prevalence and 1-year prevalence among surgical assistants, anaesthesia assistants and anaesthesiologists and (2) to determine the impact of CD on work and daily activities...

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...

INTRODUCTION: Working with cleaning products is associated with occupational contact dermatitis in health workers (HWs), but information on predictors for these outcomes is limited. OBJECTIVES: This study investigated the prevalence of work-related skin symptoms (WRSS) and associated factors in HWs exposed to cleaning agents in two Southern African tertiary hospitals. METHODS: A cross-sectional study of 697 HWs used an interviewer-administered questionnaire and assessed for atopy using Phadiatop...

BACKGROUND: Adverse drug reactions to iodinated contrast media (ICM) have risen due to their increasing use in x-ray-based imaging modalities. Delayed hypersensitivity reactions are mainly caused by nonionic monomeric compounds and represent an issue impacting the diagnostic-therapeutic pathways of cancer, cardiology and surgery patients. OBJECTIVES: To prospectively evaluate the usefulness of skin tests in delayed hypersensitivity reactions to ICM and to evaluate the tolerability of iobitridol, a monomeric nonionic low osmolality compound, as a possible safe alternative...

BACKGROUND: Propylene glycol (PG) is used in a variety of cosmetics, food and pharmaceuticals. PG is a known sensitizer but also irritating when patch tested (PT). OBJECTIVES: The aims were to investigate the frequency of contact sensitization to PG and to identify cases of allergic contact dermatitis (ACD). METHODS: A retrospective study was performed on patients PT at the Skin Health Institute (SHI), Victoria, Australia to PG 5% pet. and PG 10% aq...

BACKGROUND: During the COVID-19 pandemic, the use of face masks has increased among healthcare workers (HCWs). Questionnaire studies have shown a high frequency of self-reported facial adverse skin reactions. Case reports have been published on face mask-induced allergic contact dermatitis and urticaria. OBJECTIVES: To describe the results of the contact allergy investigations in consecutive HCWs investigated for skin reactions to face masks during the COVID-19 pandemic and the results of the chemical investigations of face masks supplied by the hospital...

BACKGROUND: Allergic contact dermatitis to gloves is mostly induced by rubber accelerators. The European baseline series (EBS) appears insufficient to detect glove allergy. Since 2017, it is recommended to use the European rubber series (ERS) and to test the patients' own gloves. OBJECTIVES: To investigate the clinical profile of glove-wearing patients with hand eczema (HE) and to evaluate their sensitisation profile to glove allergens and the value of testing the patients' own gloves...

BACKGROUND: Patients are consecutively screened for contact allergy to corticosteroids with budesonide and tixocortol-21-pivalate in the European baseline series. Centres using TRUE Test also include hydrocortisone-17-butyrate. A supplementary corticosteroid patch test series is used in case of suspicion of corticosteroid contact allergy or when a marker of corticosteroid contact allergy is positive. OBJECTIVE: The aims were to evaluate (1) the efficacy of corticosteroids in the TRUE Test and (2) co-sensitization patterns...

BACKGROUND: Hair cosmetic products contain several, partly potent contact allergens, including excipients like preservatives. Hand dermatitis in hairdressers is common, scalp and face dermatitis in clients or self-users (summarised here as 'consumers') may be severe. OBJECTIVE: To compare frequencies of sensitization to hair cosmetic ingredients and other selected allergens between female patch tested patients working as hairdressers and consumers without professional background, respectively, who were tested for suspected allergic contact dermatitis to such products...

BACKGROUND: The role of contact sensitisation in the pathogenesis of oral lichen planus (OLP) has not been clearly defined. OBJECTIVE: We aimed to evaluate relevant contact sensitisers in OLP. METHODS: A retrospective study was conducted on OLP patients who underwent patch testing from 1 January 2006 to 31 December 2020 at an Australian tertiary dermatology institution, compared to cheilitis patients patch tested over the same time period...
