Abstract
INTRODUCTION Glove-induced dermatoses are frequently seen among healthcare workers (HCWs) and are often mistakenly defined as latex allergy. OBJECTIVES To determine the prevalences of (i) the symptoms of immediate type hypersensitivity reactions, (ii) the symptoms of hand eczema, (iii) latex sensitization detected using skin prick test (SPT), and (iv) contact hypersensitivity to rubber additives or glove pieces detected using patch test, in Turkish HCWs. METHODS Ninety-eight HCWs were included in the study. All subjects completed a questionnaire. All participants were skin prick tested for latex, and foods previously identified as concomitant allergens in latex-sensitive individuals; patch tested for 7 rubber additives, 3 additional haptens, and glove pieces. RESULTS The mean age was 32.1 (± 9.4) years, and 71 (72.4%) participants were nurses. Eighty-four (85.7%) subjects had a history of mucocutaneous symptoms of immediate-type hypersensitivity occurring within the first 24 hours after latex glove contact, while 9 (9.2%) subjects demonstrated SPT positivity for latex. Eighty (81.6%) subjects had a history of glove-induced hand eczema symptoms, while patch test positivity for the rubber additives or glove pieces was in 17.3%. CONCLUSIONS About one-tenth of those with a history of glove-induced type I hypersensitivity symptoms had true latex allergy, and one-quarter of those with a history of glove-related hand eczema symptoms had contact hypersensitivity to glove products. Therefore, rote avoidance of latex use is generally ineffective in the management of glove-related skin complaints. Individual measures should focus on reducing the use of soaps and disinfectants, and promoting the use of moisturizers, rather than glove choice.

Abstract
Hand dermatitis is a common condition with a lifetime prevalence of 20%. Glove allergic contact dermatitis (ACD) is a very important dermatitis affecting health care workers, hairdressers, cleaning personnel, kitchen workers, craftsmen, construction workers, laboratory workers, and homemakers. Occupationally related cases may be severe and can result in significant disability. Glove ACD is most commonly due to exposure to rubber accelerators, which are compounds that are added to rubber during production to increase strength and durability. Given the known allergic potential of these compounds, glove manufacturing companies have reformulated gloves leading to the introduction of new rubber allergens. In this review, we will discuss risk factors for glove ACD, both common and uncommon allergens in gloves, common contact allergens that permeate gloves, and patch testing to help uncover the inciting allergen(s).

Abstract
Natural rubber latex (NRL) allergy has been recognized as a public health concern. NRL allergy frequently occurs in healthcare professionals. In this retrospective study we report the changing frequency of Type I NRL allergy amongst healthcare workers suffering from hand dermatitis referred to our department between 1996 and 2003. We identified 224 healthcare workers from the patch test database with a diagnosis of hand dermatitis who had undergone NRL skin prick testing (SPT). We report the SPT results, patch test results and diagnoses for each individual. The percentage of positive SPT to NRL in healthcare workers decreased from 62% in 1996 to 10% in 2003. Type IV allergy to fragrance mix (13%) was the most frequent cause of allergic contact dermatitis. Thiuram mix (8%) and carba mix (4%) were the most frequent indicators of type IV allergy to chemicals in rubber gloves. Fragrance allergy was the most frequent type IV allergen found in healthcare workers with hand dermatitis. We conclude that hand care preparations free from fragrance allergens should be available in all areas of clinical work.

Abstract
Out of 923 female dental nurses in the Helsinki district, 799 were interviewed using a computer-assisted telephone interview. A structured questionnaire was used to inquire about skin, respiratory symptoms, atopy, work history and methods, and exposure at work. The 328 nurses, who reported work-related dermatitis on their hands, forearms or face, were invited to an interview by an occupational physician; 245 nurses participated. 31 nurses had previously been diagnosed with an occupational skin disease (OSD). 133 nurses with a suspected OSD were selected for further clinical examinations with prick and patch testing. Among the 107 nurses examined, 22 new cases of OSD were diagnosed. There were altogether 29 cases of allergic contact dermatitis, 15 of contact urticaria, 12 of irritant contact dermatitis, and 1 case of onychomycosis. Rubber chemicals and natural rubber latex (NRL) in protective gloves, as well as dental-restorative plastic materials [(meth)acrylates], were the most common causes of allergy. 42% of the OSD cases in the studied population had been missing from the statistics (Finnish Register of Occupational Diseases). Plastic gloves or NRL gloves with a low-protein content are recommended for dental work. Skin exposure to (meth)acrylates should be avoided.

Abstract
BACKGROUND Type 1 natural rubber latex (NRL) allergy prevalence rates quoted vary due to the different populations studied and methodologies used for assessment and investigation of NRL allergy. OBJECTIVES To investigate the rate of type 1 allergy to NRL in health-care workers (HCWs) in a single NHS trust in Wales. METHODS A response rate of 3716 of 5548 (67%) of the employees was obtained with a latex allergy questionnaire administered by the occupational health departments. Type 1 NRL allergy was diagnosed by correlating clinical symptoms, skin prick testing and IgE RAST to latex in the dermatology department. RESULTS The period prevalence (1998-2001) for type 1 clinical latex allergy in HCWs was 25 of 4439 (0.56%). Of the 25 positive HCWs, 18 (72%) were nurses. CONCLUSIONS The low prevalence rate of type 1 NRL allergy should not lead to underestimating the importance of clinically significant NRL allergy and the risks that need to be minimized.

Abstract
BACKGROUND Natural rubber latex is a frequent cause of IgE-mediated allergy in hairdressers; but a non-IgE-mediated allergy to latex proteins can also occur. Sixty-one hairdressers, reporting latex glove-related symptoms, were enrolled in the study. METHODS They were evaluated for latex allergy by assessment of serum specific IgE and skin prick tests. Patients were patch tested to a rubber additive series and to latex. Proportions were compared by one-tailed Fisher's exact test; mean values of continuous variables were compared by Student's t-test. RESULTS A diagnosis of IgE-mediated latex allergy was made in 11 (18%) hairdressers; patch tests with rubber-related antigens were positive in 24 (39.3%) subjects. The most positive patch tests were those with para-phenylenediamine (33%). Two hairdressers (3.3%) showed delayed reactions to the latex sample. Hairdressers with IgE-mediated latex allergy were older and presented a personal history of atopy and local hives after exposure to latex; they were more likely to have a positive response to other allergens on prick or patch testing. CONCLUSIONS Our study demonstrates a certain number of false-positive and false-negative results when reported symptoms of possible latex sensitivity were compared to prick and CAP tests to latex, indicating the problems of relying solely on self-report.

Abstract
Although it is often claimed that health care workers are at increased risk of latex sensitization and type I allergies, there has been no systematic analysis of the epidemiologic studies that are relevant to this conclusion. A systematic analysis of the epidemiologic literature found that, in the past 14 years, there have been 48 epidemiologic studies of type I latex allergy among health care workers. Of these, 2 cohort studies estimated the incidence of latex sensitization by skin prick testing at between 1% and 2.5% per year. Neither compared the risk to that in the general population. The prevalence of sensitization in health care workers varied between 0% and 30%, yet this large variation was unexplained. Increased risk of sensitization was not clearly associated with the duration of work in health care, the time spent wearing latex gloves, the frequency of exposure, the specific job categories, the use of powdered versus nonpowdered latex gloves, the use of latex versus nonlatex gloves, or any measurements of ambient exposure to latex proteins. The epidemiologic studies do not support a conclusion that health care workers are at clearly increased risk of latex sensitization or type I allergies compared to other occupations in the United States. The role of latex gloves in causing latex sensitization and type I allergic symptoms remains poorly defined because of the inconsistent results across studies. Future epidemiologic studies are needed that include measured exposures to latex antigens, that compare health care workers to appropriate referent groups, and that address confounding by atopy, age, sex, and race.

Abstract
BACKGROUND It has been established that there are type I and type IV allergens in latex gloves. OBJECTIVE The purpose of the study was to establish the prevalence of rubber glove-induced skin symptoms among health care workers in one Italian hospital. METHODS Health care workers (n = 1584) were evaluated using a written questionnaire and 295 respondents with glove-induced skin symptoms were tested. We performed: skin prick test with latex glove extract and commercial latex, and environmental and food allergens; glove use test; patch tests with a rubber additive series; and RASTs. RESULTS Hospital employees who used or had used latex gloves at work were 1294. Three hundred and sixteen (24.4%) reported glove-induced symptoms, namely, cutaneous symptoms in all the cases and non-cutaneous symptoms in 105 subjects (8.1%). Twenty-seven of the 295 symptomatic employees tested (9.1%) were latex sensitive. Thirty-one patients (10.5%) exhibited positive patch test to rubber-related allergens. The most positive readings were obtained from the Thiuram mix and the Carba mix, with 12 and 9 positivities, respectively. The risk factors for latex skin sensitization were: a previous history of atopy and asthma; history of surgery; pre-existing hand dermatitis; work-related symptoms; and positive skin tests to common inhalant and certain foods (P < 0.05). Subjects who exhibited positive patch test were significantly more likely to have a prior hand dermatitis (P < 0.001). Of the 295 cases, 275 (93.2%) were contact dermatitis (CD), 13 (4.4%) contact urticaria (CU) (including protein CD) and 7 (2.4%) CD associated with CU. CONCLUSIONS Our results show a high prevalence of rubber glove-induced dermatoses among the employees in one Italian hospital. The majority of skin complaints of latex gloves are related to skin irritation rather than to allergy. The immediate allergy to latex and the delayed allergy to rubber chemicals suggest that all the health care workers with glove-related dermatitis should undergo both skin prick test and glove use test to detect type I hypersensitivity to latex, and patch test to detect type IV hypersensitivity to rubber chemicals.

Abstract
O látex está sendo considerado o alergênico do ano 2000, tendo em vista que inúmeros indivíduos, principalmente profissionais da área de saúde e pacientes submetidos a várias intervenções diagnósticas e terapêuticas, estão freqüentemente expostos aos alérgenos do látex, presentes em produtos de borracha natural. As manifestações clínicas conseqüentes às reações alérgicas de hipersensibilidade imediata vão desde rinite, urticária, conjuntivite, angioedema, asma, até anafilaxia. Estudos recentes estão demonstrando que pacientes alérgicos ao látex desenvolvem concomitantemente sensibilização a certos alimentos de origem vegetal, especialmente frutas como papaia, figo, banana, abacate, kiwi, pêssego, abacaxi, melão e castanha, acreditando-se numa provável ocorrência de reações cruzadas entre os alérgenos do látex e destas frutas. Faz-se, então, uma revisão sobre a alergia ao látex, em particular sobre os grupos de risco, incluindo a presença de reatividade cruzada entre o látex e as frutas.

Abstract
Recently anaphylactic shock caused by latex gloves and medical instruments has been discussed as an important problem in surgical operations. Patients with contact urticaria or anaphylaxis due to natural rubber latex were first reported in Japan in 1993, and the number of cases is gradually increasing. In the present study, we analyzed 28 patients examined in our clinic from 1993 to 1998. The diagnosis of latex allergy was made on the basis of clinical history, latex specific IgE antibody, skin test, and use test. The 3 male and 25 female patients included 20 nurses, 4 doctors, 2 housewives, one animal hospital employee, and one worker in a senile rehabilitation center. The majority were health care workers. Contact urticaria from rubber gloves was the most common clinical symptom. Some of the patients developed severe attacks of anaphylaxis. During the period from 1995 to 1997, we also performed a questionnaire study and a serum examination of latex specific IgE antibody among the personnel of our university hospital. The screening test for the antibody was more reliable than our questionnaire study in detecting latex-sensitive persons. The prevalence of latex allergy was found to be 4.6%. This indicates that not only dermatologists but also all hospital workers should be aware of this type of allergy.

Abstract
Type I allergy to natural rubber latex can be an important health problem for latex-exposed individuals (e.g., health care workers, spina bifida children). Also beyond these risk groups, a high sensitization rate of varying and partly unknown clinical relevance has been reported. Atopy represents a risk factor for latex allergy and recent studies indicate that patients suffering from pollen allergies may have pollen allergen-specific IgE antibodies which cross-react with latex allergens. In order to investigate whether sensitization to pollen allergens can have priming effects on the production of IgE antibodies against latex in vivo, a mouse model was established. Groups of 10 BALB/C mice were immunized with Al(OH)3-adsorbed pollen extracts from timothy grass, ragweed, mugwort, or birch. For control purposes, one additional group received adjuvant only and another group was not immunized. Half of the mice of each group were subsequently immunized with Al(OH)3-adsorbed latex glove extract, the other half with adjuvant only. Pollen and latex-specific IgE- and IgG1-antibody responses were analyzed by enzyme-linked immunosorbent assay and statistically evaluated by analysis of variance. Antibody responses to cross-reactive antigens were investigated by immunoblotting. We found significantly increased IgE reactivities to latex after pollen sensitization and vice versa. Moreover, mice immunized with timothy grass pollen extract alone - without subsequent latex immunization - displayed IgE reactivity to latex. Cross-reactive antibodies were directed against pollen antigens of approximately 60 kDa molecular weight. Our results thus demonstrate a mutual boosting effect of pollen and latex sensitization in vivo which may be also operative in polysensitized plant allergic patients.

Abstract
OBJECTIVES To determine the prevalence and risk factors for symptoms related to gloves, and the relation between symptoms and immunological evidence of type 1 hypersensitivity to latex in a United Kingdom health care setting. METHODS A cross sectional survey was carried out among 773 employees at a British hospital. A self administered questionnaire was used to collect information about symptoms related to gloves and associated risk factors in a sample of hospital staff who were likely to use gloves at work. All of those who reported symptoms suggestive of type 1 hypersensitivity were invited for skin prick testing and measurement of specific IgE to latex (RAST). RESULTS Among the 372 responders, symptoms related to gloves were common, 49% reported redness or itching of the hands, 14% reported urticaria, and 6% reported chest tightness. However, the frequency of positive skin prick tests and RASTs was surprisingly low (only two subjects tested positive). CONCLUSIONS These findings indicate the need for caution in the interpretation of symptoms related to gloves even when they seem to suggest type 1 hypersensitivity.
