Abstract
Natural rubber latex is a widely used industrial raw material to produce many consumer and commercial products. Chronic exposures to latex allergenic proteins residual in the finished products can promote hypersensitive immune responses, which affects millions of workers and the general public worldwide. Research has shown the average prevalence of latex allergy worldwide remains approximately 10% among healthcare workers, 7% among susceptible patients, and 4% among general population. Although most effective in preventing latex allergy, completely avoiding contact to latex-derived products is extremely challenging, given the fact that millions of products possibly contain latex, but few are regulated and properly labeled. Due to the difficulty to assure a product completely absent of latex allergens, the United States Food and Drug Administration has recommended to stop using labels like "latex-free" or "does not contain latex." Here we evaluate published data, industrial standards and regulations, identify possible countermeasures, and propose an integrated strategy, including some more practicable approaches (e.g., education/training, product labeling, the use of proper personal protective equipment, occupational selection, and searchable product database) and novel medical treatments (e.g., immunotherapy) to help decreasing latex allergy prevalence.

Abstract
OBJECTIVE Health care workers are at risk for work-related asthma, which may be affected by changes in cleaning practices. We examined associations of cleaning tasks and products with work-related asthma in health care workers in 2016, comparing them with prior results from 2003. METHODS We estimated asthma prevalence by professional group and explored associations of self-reported asthma with job-exposure matrix-based cleaning tasks/products in a representative Texas sample of 9914 physicians, nurses, respiratory/occupational therapists, and nurse aides. RESULTS Response rate was 34.8% (n = 2421). The weighted prevalence rates of physician-diagnosed (15.3%), work-exacerbated (4.1%), and new-onset asthma (6.7%) and bronchial hyperresponsiveness symptoms (31.1%) were similar to 2003. New-onset asthma was associated with building surface cleaning (odds ratio [OR], 1.91; 95% confidence interval [CI], 1.10-3.33), use of ortho-phthalaldehyde (OR, 1.77; 95% CI, 1.15-2.72), bleach/quaternary compounds (OR, 1.91; 95% CI, 1.10-3.33), and sprays (OR, 1.97; 95% CI, 1.12-3.47). CONCLUSION Prevalence of asthma/bronchial hyperresponsiveness seems unchanged, whereas associations of new-onset asthma with exposures to surface cleaning remained, and decreased for instrument cleaning.

Abstract
Occupational contact dermatitis is the most common occupational skin disease (OSD), and most of them are irritant in nature. There is less information available about contact urticaria than contact dermatitis. There are several strategies to prevent OSD, although workplace studies suggest there are gaps in their use in the workplace. Because early detection leads to improved outcomes, screening for dermatitis in industries such as health care would be useful. Both diagnosis and management involve 2 components: the actual disease diagnosis and medical treatment and the work-relatedness and management of the workplace to reduce exposures.

Abstract
The purpose of this study was to assess the effectiveness of two different surgical gloves (powdered latex and powder and latex free) for glove perforation frequency, problems and satisfaction with glove usage and manual dexterity levels during surgical operations that include scrub nurses. Scrub nurses wore antiallergenic gloves (powder and latex free) gloves during three operations, double latex and powdered gloves during three operations and single latex and powdered gloves during three operations. The gloves were checked for punctures after each surgery with a water-inflation test. In our study, 19% of single gloves and 18.1 % of double gloves and 4.8% of powder and latex free worn by scrub nurses were punctured during surgery. None of the inner gloves in double gloves were punctured. Although wearing double gloves restricts manual dexterity, results in discomfort problems such as perspiration and fetor and results in a low satisfaction rate among scrub nurses, double gloves are protective against injuries and punctures.

Abstract
PURPOSE OF REVIEW Allergy to natural rubber latex (NRL) reached epidemic proportions during the nineties and led to intense preventive efforts. The aim of this review was to provide a comprehensive compilation of the current status of occupational NRL allergy. RECENT FINDINGS Recent advances led to the characterization of 15 NRL allergens and the development of assays for measuring the allergen content of NRL materials and specific IgE antibodies against NRL allergen components. Preventive measures aimed at reducing workplace exposure to NRL allergens were associated with decreasing incidence rates of NRL allergy. However, a pooled analysis of epidemiological surveys published during the last 10 years provided prevalence estimates of NRL sensitization and allergy similar to those derived from studies conducted before 2003. Substantial progress has been made in the understanding and prevention of NRL allergy, although the disease may still remain a worldwide cause of concern.

Abstract
Objectives: This article aims to review the current prevalence rate of latex allergy among healthcare workers, susceptible patients, and the general public, and to investigate why latex is still a ubiquitous occupational health hazard. Methods: Scientific publications on PubMed, particularly those published within the last five years, and current regulations from agencies such as Food and Drug Administration (FDA) were reviewed. Consumer and commercial products that may contain latex were also surveyed. Results: Approximately 12 million tons of natural rubber latex is produced annually and is widely used to manufacture millions of consumer and commercial products. Only limited number of latex-derived products have been approved and regulated by government agencies, such as FDA, whereas the majority of finished products do not label whether they contain latex. Owing to millions of unidentifiable products containing latex and many routes for exposure to latex, preventing contact with latex allergens and reducing the prevalence of latex allergy are more difficult than expected. Reported data suggest that the average prevalence of latex allergy worldwide remains 9.7%, 7.2%, and 4.3% among healthcare workers, susceptible patients, and general population, respectively. Conclusions: Latex-derived products are ubiquitous, and latex allergy remains a highly prevalent health risk in many occupations and to the general population. Developing alternative materials and increasing the ability to identify and label latex-derived products will be practicable approaches to effectively control the health risks associated with latex.

Evaluation of a prospectively administered written questionnaire to reduce the incidence of suspected latex anaphylaxis during elective cesarean delivery. Int J Obstet Anesth 2014; 23:335-40. [PMID: 25201315 DOI: 10.1016/j.ijoa.2014.05.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2013] [Revised: 04/30/2014] [Accepted: 05/28/2014] [Indexed: 11/24/2022]
Abstract
BACKGROUND Life-threatening anaphylaxis has been reported in women exposed to latex during surgery. We compared a written screening questionnaire to identify suspected latex sensitivity with a verbal inquiry used previously in a historical control group of women undergoing cesarean delivery to determine if the incidence of suspected latex anaphylaxis could be reduced. METHODS To identify suspected latex sensitivity among women undergoing elective cesarean delivery in a single-site tertiary unit, a nine-item written screening questionnaire was compared to historical use of a standard verbal inquiry "Are you allergic to medications or latex?". Women who had suspected latex sensitivity risk factors, or who had known latex allergy, underwent latex-free surgery. Women with suspected anaphylaxis during cesarean delivery were recommended to undergo allergen testing. The primary study outcome was suspected anaphylaxis incidence during the two periods: historical control January to December 2008, questionnaire March 2010 to April 2011. RESULTS The questionnaire identified suspected latex sensitivity in 66 of 453 women (14.6%) who completed the questionnaire. The standard verbal inquiry group had identified 12 of 460 women (2.6%) with self-reported latex sensitivity. The incidence of suspected anaphylaxis during cesarean delivery was significantly lower during the questionnaire period when compared to historical controls (3/516, 0.6% vs. 11/460, 2.4%, P=0.015). For both groups, 13 of 14 women (92.9%) with suspected latex anaphylaxis were contactable; five of 13 (38.5%) had undergone allergen testing and all were positive for latex. CONCLUSIONS Use of the written screening questionnaire was associated with fewer cases of suspected anaphylaxis during cesarean delivery compared with the historical control. Most women with suspected anaphylaxis did not perform allergy testing; however, all who did were positive for latex.

Abstract
OBJECTIVES To assess the incidence of sensitization and gloves-related symptoms in 10-year follow-up in a group of health care workers (9,660 person-years) using non-powdered latex gloves from 2000 to 2009 and to examine related factors. MATERIALS AND METHODS We studied 2,053 health care workers in Trieste Hospitals by means of skin prick test for latex extract, patch tests and medical examinations. We report the incidence of latex sensitization among workers using non-powdered latex gloves. RESULTS The incidence of latex sensitization, rhinitis, asthma, urticaria, irritant and allergic contact dermatitis were 1.0; 0.12; 0.21; 0.72; 2.39 and 2.50 cases per 1,000 person-years, respectively. Respiratory symptoms and urticaria were positively related with latex sensitization (OR = 8.0; 95 % CL 1.27-48.6), with common allergic respiratory symptoms (OR = 4.19; 95 % CL 1.04-16.8) and with familial atopy (OR = 4.47; 95 % CL 1.1-17.9). CONCLUSION The incidence of latex sensitization and latex-related symptoms were very low but subjects with allergic symptoms related to common allergens are at higher risk. The use of non-latex gloves is suggested for them.

Abstract
IgE-mediated allergy to natural rubber latex was first noted from rubber gloves in 1979. The initial reports in dermatological journals described contact urticarial reactions; later, severe generalized allergic reactions and asthma were documented. A considerable proportion of the people involved in medical and dental care were found to be sensitized to latex. This article describes and surveys a broad range of primary prevention measures at the local and national levels. Examples are given from paediatrics, dental education, and medical care. National strategies and position papers on latex allergy are presented in which medical professionals, manufacturers and public authorities have cooperated. Special reference is paid to the European work to standardize medical gloves, which led to document EN 455:3.
