ABSTRACT

BACKGROUND: Allergic contact dermatitis (ACD) from rubber glove usage is usually caused by rubber additives such as the accelerators. However, in analyses of the suspected gloves, ordinary rubber allergens are not always found. Accelerator-free rubber gloves are available, but some patients with accelerator allergy do not tolerate them and might also be patch test positive to them. OBJECTIVES: To identify and chemically characterize a new allergen, 2-cyanoethyl dimethyldithiocarbamate (CEDMC), in rubber gloves. We describe two patient cases: patient 1 that led us to the identification of CEDMC and patient 2 with occupational ACD caused by CEDMC. METHODS: The patients were examined with patch testing including baseline and rubber series, and their own rubber gloves. High-performance liquid chromatography (HPLC) was used for chemical analysis of rubber gloves. The allergen was synthesized and identified by nuclear magnetic resonance, mass spectrometry and infrared spectrometry, and tested on patient 2. RESULTS: CEDMC was identified by HPLC in a nitrile glove associated with hand eczema in patient 1. Patient 2 whose nitrile gloves contained CEDMC was patch test positive to CEDMC. CONCLUSIONS: CEDMC is a new contact allergen in nitrile gloves and probably forms during vulcanization from residual monomer acrylonitrile and rubber additives.

ABSTRACT

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. METHODS: We conducted a French multicentre study of patients evaluated for HE between 2018 and 2020 and tested with the EBS, the ERS and their own gloves in patch tests and semi-open (SO) tests. RESULTS: A total of 279 patients were included; 32.6% of patients had positive tests to their own gloves or to glove allergens. Almost 45% of the sensitisations to glove allergens were detected only by the ERS. Among the patients tested both in patch tests and SO tests with their own gloves with positive results, 28% had positive SO tests only. Polyvinylchloride (PVC) gloves were positive in four patients. CONCLUSION: Our series confirms the need to test the ERS. All the patients' gloves must also be tested including PVC gloves. SO tests with gloves are useful as a complement to patch tests.

ABSTRACT

BACKGROUND: Semipermeable gloves might be an alternative to cotton gloves in management of hand dermatoses. OBJECTIVES: To compare acceptance and tolerability of gloves made of cotton or a semipermeable Sympatex membrane in patients with hand dermatoses and their effect on skin lesions when worn overnight. METHODS: A total of 199 patients with work-related symmetrical hand dermatoses were asked to wear a cotton glove (COT) on one hand and a Sympatex glove underneath a cotton glove (SYM/COT) on the other hand for 19 consecutive nights. The severity of skin lesions was regularly examined. A questionnaire on acceptance and tolerability was used in a subset of 126 patients. RESULTS: Data on skin lesions were available for 183 participating patients (92%). The severity did not differ substantially between hands covered with SYM/COT or COT over time. Questionnaire data were available for 120 patients (95%). SYM/COT received better ratings regarding climate conditions while COT showed superiority in wearing comfort, practicality and appearance. CONCLUSIONS: Both SYM/COT and COT were well tolerated and accepted in patients with hand dermatoses. Hence, SYM/COT may serve as suitable alternative for COT as comfort gloves supporting therapeutic efforts. The observed slight differences may influence the decision when selecting the glove type.

ABSTRACT

The recent coronavirus disease 2019 (COVID-19) pandemic has led to the dramatic increase in use of personal protective equipment (PPE) among health care providers and the general public. Herein the authors discuss the various occupational dermatoses including allergic and irritant contact dermatitis, acne, seborrheic dermatitis, and rosacea related to frequent handwashing, disinfecting of surfaces, and prolonged wear of various PPE including face masks, gloves, and gowns. The authors provide an overview of published PPE-associated occupational dermatoses during the COVID-19 pandemic and also discuss prevention strategies and treatment options to help patients with these complaints.

ABSTRACT

BACKGROUND: Nurses, as the largest group of health professionals, are at the frontline of the healthcare system in response to COVID-19 epidemic. This study aimed to evaluate the nurses' certainty and satisfaction with medical gloves when exposed to coronavirus in Fars province, south of Iran. METHODS: Using convenience sampling, 400 hospital nurses during the COVID-19 outbreak were selected from eight hospitals of Shiraz University of Medical Sciences (SUMS). A questionnaire about glove reliability, including protection in tasks, durability, integrity and tear resistance, feeling fearful, and focusing on duties, and the nurses' anxiety regarding their infection with coronavirus was distributed to the selected nurses to complete. 375 questionnaires were completed (response rate of 93.75%). Among the participants, 180 (48%) were in the corona section and 195 (52%) were hardly possible to have contact with coronavirus pneumonia patients. RESULTS: The mean score (SD) of anxiety about infection with COVID-19 for nurses in the COVID-19 section and those in the non-COVID-19 section were 6.08 (2.8) and 4.56 (2.58), respectively (p<0.05). The mean duration of gloves usage in a day was almost similar in the two groups (about 5h), but the number of glove replacements was significantly higher among the nurses in the corona section (6 times) compared to those in the non-corona section (3 times). The two groups were also significantly different regarding glove protection in daily tasks and glove durability. CONCLUSION: The nurses in the corona section had more concerns about medical gloves as a type of personal protective equipment. In addition to health education on controlling and preventing the spread of diseases, raising awareness about the reliability of personal protective equipment can improve nurses' performance.

ABSTRACT

BACKGROUND: Children with psoriasis may have been directly impacted by the COVID-19 pandemic and their illness may also have affected their ability to follow preventive measures. OBJECTIVE: To investigate the impact of the COVID-19 pandemic on children with psoriasis. METHODS: A survey of children (<18 years) with psoriasis, conducted from June 10 to June 29, 2020. RESULTS: In total, 92 children were included: 71.7% had psoriasis lesions at the time of home lockdown while 45.2% were receiving systemic treatments, and two contracted COVID-19. During lockdown, psoriasis worsened in 47.3% of the children and 18.8% stopped their systemic treatments, mainly for reasons linked to the pandemic. A total of 41.3% had a consultation for psoriasis during lockdown (71.1% by teleconsultation): 39.5% due to worsening of their psoriasis and 21.1% for pandemic-related issues. Among patients not having a consultation during lockdown, 27.5% had a cancellation by the doctor and 9.3% had concerns over going to see the doctor. Finally, 22.8% of patients reported finding it difficult to respect hygiene measures because of their psoriasis, e.g., application of alcohol-based hand sanitizers (47.6%), handwashing routines (42.9%), and wearing a mask (28.6%). CONCLUSIONS: This study demonstrates the major clinical impact of the COVID-19 pandemic on children with psoriasis. Teleconsultations played a key role in patient management as regards patient monitoring, provision of information, and renewal of treatments. It is vital that we learn from these data to improve and adapt the monitoring of chronic dermatoses in both children and adults in the event of a future health crisis.

ABSTRACT

Because of COVID-19 outbreak people wash more often their hands and use more often and longer disposable gloves. The natural skin barrier function is damaged by washing hand or using disinfectants, because of this allergic and irritative hand eczema develops. Allergic hand eczema can be caused by materials which people work with, and by ingredients of creme and soap, but also by wearing gloves. To prevent hand eczema, good protection of the hands is essential. It is very important to have knowledge about different gloves to inform (health) worker about wearing gloves in the proper way.

ABSTRACT

BACKGROUND: The causative chemicals responsible for nitrile rubber glove-induced allergic contact dermatitis have not been fully elucidated. SUBJECT: This case involved a 36-year-old female, who developed an erythematous rash on her hands after one and a half months of wearing nitrile rubber gloves at her workplace. METHODS: Patch tests were performed using the gloves as is, and the Japanese standard allergen 2008 and their components. The gloves were chemically analyzed and several detected substances were subjected to further patch testing. RESULTS: The patient exhibited positive patch test reactions to nitrile rubber gloves as is, as well as to the dithiocarbamate mix and thiuram mix in the Japanese standard allergen 2008. Further patch testing revealed positive reactions to zinc diethyldithiocarbamate (ZDEC) and tetraethylthiuram disulfide (TETD) and weak positive reactions to zinc dimethyldithiocarbamate (ZDMC) and tetramethylthiuram monosulfide (TMTM). Chemical analysis revealed that ethyl isothiocyanate (EITC) and butyl isothiocyanate (BITC), which might have been produced from dithiocarbamate-type accelerators (DTCs) or thiuram-type accelerators (thiurams) during the vulcanization process, were present in the nitrile rubber gloves the patient used at her workplace, as was ZDBC. No other DTCs or thiurams were detected. Patch testing of the detected materials produced positive reactions to EITC and BITC, but not to ZDBC. CONCLUSION: We diagnosed the patient with allergic contact dermatitis due to the EITC and BITC present in nitrile rubber gloves, and considered that alkyl isothiocyanate might also have played a causative role. We propose that nitrile rubber gloves should be produced without using vulcanization accelerators.

ABSTRACT

BACKGROUND: Studies on patch testing with workplace materials and evaluation of current occupational relevance of positive patch test reactions are scarce in patients with occupational dermatitis (OD). OBJECTIVES: To identify frequent sensitizations with occupational relevance and to determine the value of patch testing with workplace materials in OD patients. PATIENTS AND METHODS: Results and clinical data of 654 patients with suspected OD patch tested between 2013 and 2017 were analysed. RESULTS: Occupational allergic contact dermatitis was diagnosed in 113 (17.3%) patients. Mechanics had the widest range of occupational sensitizations. Sensitization to epoxy resin was rated occupationally relevant in almost all handicraft trades. Among positive patch test reactions to workplace products, those to water-based metal working fluids and leave-on cosmetic products were most frequent. Despite frequent testing, protective gloves only rarely elicited positive reactions. Preservatives and rubber compounds were most frequently identified as currently occupationally relevant. CONCLUSIONS: Rubber allergy is occupationally relevant especially in healthcare workers and cleaners. Generally, preservatives including formaldehyde releasers are important allergens in OD patients. Leave-on cosmetic products must not be forgotten as allergen sources. Patch testing both workplace materials and standardized test preparations has a complementary value and is beneficial for the diagnostic work-up of OD patients.

ABSTRACT

BACKGROUND: In the current situation of the COVID-19 pandemic, healthcare workers (HCWs) have to comply with hygiene conditions and use gloves more frequently and for a longer period of time than they would previously to avoid infection and prevent transmission. AIMS: We aimed to characterize the adverse skin reactions occurring after hand hygiene and glove use in HCWs in a tertiary university hospital to determine the possible causative factors and whether the use of these measures is affected. METHODS: Between April 15 and May 1, 2020, a cross-sectional survey was conducted, using online questionnaire, answered by HCWs in a tertiary university hospital. RESULTS: The increase in general hand-skin problems during the pandemic period was statistically significant (P = .004). The most common symptom was dryness. During the pandemic period, 67 (24.3%) HCWs thought that the conditions were caused by glove use, and 197 (71.4%) thought that they were due to alcohol-based hand antiseptics. The incidence of other hand-skin conditions except for vesicles was statistically higher in women than in men (P < .001). CONCLUSIONS: Increased number of hand-skin conditions during the pandemic should not be ignored, since hand hygiene and glove use are expected to increase.
