Inventory of the chemicals and the exposure of the workers’ skin to these at two leather factories in Indonesia

Purpose

Tannery workers are exposed to hazardous chemicals. Tannery work is outsourced to newly industrialized countries (NICs) where attention into occupational health hazards is limited. In this study, we investigated the skin exposure to hazardous chemicals in tannery workers and determined the prevalence of occupational skin diseases (OSDs) at tanneries in a NIC.

Methods

A cross-sectional study on the observation of the working process and an inventory and risk assessment of the chemicals used. Classification of chemicals as potential sensitizers/irritants and a qualitative assessment of exposure to these chemicals. Workers were examined and interviewed using Nordic Occupational Skin Questionnaire-2002/LONG.

Results

The risk of OSDs at the investigated tanneries was mainly related to the exposure of the workers’ skin to chemicals in hot and humid environmental conditions. In 472 workers, 12% reported a current OSD and 9% reported a history of OSD. In 10% of all cases, an OSD was confirmed by a dermatologist and 7.4% had an occupational contact dermatitis (OCD). We observed that personal protective equipment (PPE) used was mainly because of skin problems in the past and not as a primary protection against OSD.

Conclusion

We observed a high frequency and prolonged exposure to many skin hazardous factors in tannery work although PPE was relatively easily available and which was generally used as a secondary preventative measure. The observed point-prevalence in this study was at the same level as that reported for other high-risk OSDs in Western countries and other tanneries in NICs. However, the observed point-prevalence in this study was lower than that reported in India and Korea. The results of our study and those of other studies at tanneries from other NICs were probably influenced by Healthy Worker Survivor Effect (HWSE).     

Occupational skin diseases in Czech healthcare workers from 1997 to 2009

Background

The healthcare sector ranked in second place among economic sectors in the Czech Republic, with about 11.4 % of all occupational diseases in 2009. Skin diseases constituted about 20 % of all occupational diseases.

Objectives

The aim of this study was to analyze the causes and trends in allergic and irritant-induced skin diseases in the healthcare sector.

Methods

The data concerning occupational skin diseases (Chapter IV of the Czech List of Occupational Diseases, non-infectious skin illnesses) in the healthcare sector were analyzed from the Czech National Registry of Occupational Diseases from 1997 until 2009. The trends in the total counts and most frequent causes were evaluated.

Results

During the past 13 years, a total of 545 skin diseases were acknowledged in healthcare workers. Allergic contact dermatitis was diagnosed in 464 (85 %), irritant contact dermatitis in 71 (13 %) and contact urticaria in 10 subjects (2 %). Ninety-five percent of the patients were females. The overall incidence in individual years varied between 1.0 and 2.9 cases per 10,000 full-time employees per year. Disinfectants were the most frequent chemical agents causing more than one third of all allergic skin diseases (38 %), followed by rubber components (32 %) and cleaning agents (10 %).

Conclusion

A general downward trend of diagnosed cases of occupational skin diseases in heath care workers in the Czech Republic over the past 13 years was demonstrated.     

Occupational allergic and irritant contact dermatitis in workers exposed to polyurethane foam

Objectives

To evaluate sensitization to chemicals present in work environment after an outbreak of contact dermatitis in workers of vehicle equipment factory, exposed to polyurethane foam, based on 4,4′-diphenylmethane diisocyanate (MDI).

Material and Methods

From among 300 employees, 21 individuals reporting work-related skin and/or respiratory tract symptoms underwent clinical examination, patch testing, skin prick tests, spirometry and MDI sIgE measurement in serum. Patch tests included isocyanates series, selected rubber additives, metals, fragrances, preservatives, and an antiadhesive agent.

Results

Clinical examination revealed current eczema in the area of hands and/or forearms in 10 workers. Positive patch test reactions were found in 10 individuals, the most frequent to diaminodiphenylmethane and 4-phenylenediamine (7 persons). Reactions to an antiadhesive agent were assessed as irritant (5 workers). Except for sensitization to common aeroallergens, no significant abnormalities were found in the remaining tests. Occupational allergic contact dermatitis was diagnosed in 7 workers, irritant contact dermatitis in 10 and coexisiting allergic and irritant contact dermatitis in 3 workers.

Conclusions

In workers manufacturing products from polyurethane foam, attention should be paid to the risk of developing contact dermatitis. Skin problems in our study group were attributable probably to insufficient protection of the skin.     

Occupational respiratory and skin diseases among Finnish machinists: findings of a large clinical study

Purpose

Machinists are exposed to many sensitizing and irritant substances, but no previous study has assessed the occurrence of clinically verified occupational diseases in an unselected large workforce of machinists. Our aim was to study the occurrence of clinically verified occupational respiratory and skin diseases cross-sectionally in a large sample of machinists in southern Finland.

Methods

A computer-assisted telephone interview on occupational exposures and health was carried out in a sample of 961 machining workers from 64 metalworking companies. Of these, 757 (79 %) answered the interview. A total of 245 subjects reported work-related respiratory or skin symptoms and were invited to clinical examinations; 138 of these underwent a clinical interview and examination by an occupational health physician. On the basis of this examination, 32 subjects were further examined at the Finnish Institute of Occupational Health (FIOH) for occupational skin or respiratory diseases.

Results

One case of occupational asthma (OA) and seven cases of occupational dermatoses (OD) were diagnosed, giving a prevalence of 0.13 % (95 % CI 0–0.39) for OA, and 0.92 % (95 % CI 0.24–1.16) for OD. The OA was induced by the patient’s own MWF. Additional five cases of newly diagnosed non-occupational asthma (0.79 %, 95 % CI = 0.16–1.42) were detected. No cases of occupational rhinitis or COPD were diagnosed. The dermatoses diagnoses consisted of four cases of allergic contact dermatitis and three cases of irritant contact dermatitis. The most common causes of the ODs were MWFs.

Conclusion

This large clinical study of machinists representing metalworking in South Finland showed a prevalence of 0.13 % of OA and 0.92 % of OD. This relatively low occurrence of occupational diseases may reflect the strict Finnish criteria for the diagnosis of these occupational diseases and the relatively good level of occupational hygiene in machining workshops in Finland. Reported respiratory and skin symptoms were common, and these milder conditions may be linked to irritant rather than sensitizing exposures.     

Occupational hazards and self-reported health problems of butchers in Ibadan, southwest Nigeria

Aim

Butchers are engaged in small-scale enterprises and their work involves contact with live animals, their carcasses, blood and body fluids. The purpose of this study was to assess the occupational hazards and health problems of butchers in Nigeria.

Subjects and methods

A cross-sectional design was used. Questionnaires were administered to butchers in selected markets and abattoirs in Ibadan, southwest Nigeria to collect information on socio demographic and occupational characteristics, perceived occupational hazards and health problems. Their hands were examined for evidence of dermatitis. Chi-squared test was used to test associations between health problems and butchers’ characteristics.

Results

Four hundred and eighty-five butchers participated in the survey, 434 males (90 %) and 52 females (10 %). Perceived occupational hazards reported were knives, 400 (82 %), live cows 111 (23 %) and bones 28 (6 %) all of which cause injury. Other hazards reported were dirty environment, 17 (3 %), wet/slippery floors 7 (1 %) and hot water 6 (1 %). Current health problems were low back pain, muscular and joint pain, eye irritation and knife injuries. Apprentices reported more knife injuries than butchers, 22 and 12 % respectively x ²?=?9.42, p?=?0.04. Hand dermatitis was seen in 11 % of butchers and was more prevalent among females than males, 24 % and 9 % respectively x ²?=?7.63, p?=?0.02.

Conclusion

The main health problems reported by butchers were musculoskeletal disorders and injuries. Occupational health intervention for these workers should address injury prevention, wound care, the use of appropriate protective clothing and correct postures at work.     

Skin disease in paper mill workers

BACKGROUND: Paper mill workers have frequent and prolonged exposure to skin irritants and allergens and may have a higher risk of developing occupational dermatitis. Aims The aim of this study was to determine the extent of skin problems in a paper mill and how much was attributable to contact with allergens. METHODS: A cross-sectional study was carried out among 80 paper mill workers having daily exposure to skin irritants and allergens. They all completed a questionnaire, underwent a standard interview and physical examination. Workers whose history indicated possible contact allergy were patch tested and prick tested. RESULTS: Workers reported a high exposure to skin irritants, especially when carrying out tasks that caused the hands and feet to become wet from perspiration and having contact with process water. Atopic dermatitis was seen in 3% of the workers. Contact dermatitis was seen in 26% of the workers and 36% were diagnosed with mycosis of the feet. All cases of contact dermatitis and mycosis could be attributed to occupational exposure to skin irritants. No cases of relevant contact allergy were seen. CONCLUSION: Occupational dermatitis in paper mills is primarily related to the exposure to skin irritants. Occupational physicians should be aware of the risk of occupational dermatitis in paper mill workers.     

Evaluation of structured patient education in occupational skin diseases: a systematic assessment of the disease-specific knowledge

Purpose

The aim of this study was to evaluate the effectiveness of patient education in occupational skin diseases (OSD) regarding changes of the disease-specific knowledge.

Methods

One hundred and five patients participated in structured patient education as part of an interdisciplinary outpatient prevention measure. In a prospective one-group pre–post-design, the disease-specific knowledge was assessed with the validated “Occupational Skin Diseases Knowledge Questionnaire” (OSD-KQ) before (T0) and after the intervention (T1). A subcohort (n = 68) was examined 2–3 months later (T2).

Results

The mean OSD-KQ score significantly improved from 38.5 (59.2 % of correct answers, T0) to 55.6 (85.5 % of correct answers, T1). A pronounced heterogeneity was observed among the participants regarding the pre-interventional knowledge (10.8–84.6 % of correct answers, T0) and the individual knowledge gain. Patients who worked in health-related occupations scored significantly higher. Age and sex did not influence the knowledge. In a subcohort, a significantly improved disease-specific knowledge of 52.3 (80.5 % of correct answers) could still be found 2–3 months after the intervention (T2).

Conclusions

Structured patient education significantly improves the disease-specific knowledge in patients with OSD. The study indicates not only positive short- but also sustainable long-term effects on the knowledge gain. The OSD-KQ can serve as a tool to evaluate and improve patient education. Health educators need to be aware of the heterogeneity regarding the participants’ knowledge and take this into account during educational practice. Additional counseling may be necessary to meet the individual learners’ needs.     

Respiratory health and breath condensate acidity in sawmill workers

Purpose

The aim of the study was to evaluate exhaled breath condensate acidity (EBC pH) as a biomarker of airway response to occupational respiratory hazards present in sawmill.

Methods

Sixty-one sawmill workers in total (26 from Sawmill 1 and 35 from Sawmill 2) provided EBC samples at the beginning and at the end of the working week. Respiratory symptoms, lung function, bronchodilator test and atopy status were assessed. Occupational environment was checked for the levels of respiratory hazards.

Results

Airborne dust concentrations were below threshold limit value. Endotoxin in Sawmill 1 and Sawmill 2, and moulds in Sawmill 1 were at the levels able to induce inflammatory response in the airways. Mould levels were 2.5 times higher in Sawmill 1 than in Sawmill 2. Compared to Sawmill 2 workers, lower spirometry values, higher prevalence of dry cough and positive bronchodilator test were found in Sawmill 1 workers. Monday EBC pH values did not differ between sawmills, but declined after one working week in Sawmill 1 workers (from 7.88 to 7.49, P = 0.012) and not in Sawmill 2 workers. Similar results were obtained when only respiratory healthy non-smokers were analysed. Monday-to-Friday change of other respiratory parameters was not observed.

Conclusion

The results suggest EBC pH as a biomarker of acute respiratory effects related to occupational exposure to respiratory hazards in sawmills, presumably increased mould levels. The effect was present even at subclinical level, namely in respiratory healthy subjects. The long-term health implications remain unclear and should be evaluated in a follow-up study.     

Skin cancer preventative behaviors in state park workers: a pilot study

Objectives

Considering the potential for occupational sun exposure among state park workers, the purpose of this pilot study was to identify skin cancer knowledge, health beliefs, self-efficacy, and sun protection behaviors (SPBs) among state park employees.

Methods

The current study used a cross-sectional survey research design with state park workers in a Southern state. Of the 94 possible employees who could have participated in the study, 87 completed the survey.

Results

Assessment of the participants’ skin cancer knowledge demonstrated an average correct response rate of 68.8 %. While the vast majority (87.4 %) believed that skin cancer is a serious disease, a minority (42.5 %) believed they would develop skin cancer sometime during their lifetime, and even fewer (35.6 %) believed their risk was higher than average. Collectively, workers reported low levels of SPBs. The most commonly reported barriers to sun protection were “inconvenient,” “too hot to wear,” and “forget to protect.” Half of the participants (50.6 %) were highly confident in their ability to wear long pants while in the sun. About the same proportion of participants was highly confident they could wear a wide-brimmed hat (21.8 %) and sunscreen (20.7 %).

Conclusions

Based on available evidence, a need exists to develop individual and worksite programs and interventions to increase skin cancer prevention behaviors among this occupational group. This data could serve as a baseline to monitor and evaluate the efficacy of these interventions.     

Incidence by occupation and industry of work-related skin diseases in the United Kingdom, 1996-2001

BACKGROUND: Work-related skin disease is common but few cases are documented in statutory reports or disability systems. Voluntary reporting by specialist physicians provides more complete information. AIMS: To summarize incidence rates of work-related skin diseases reported by consultant dermatologists and occupational physicians, with emphasis on contact and allergic dermatitis by occupation and industry. METHODS: Cases reported in 1996-2001 to the EPIDERM and OPRA national surveillance schemes were analysed by causal agent, occupation and industry, with incidence rates calculated against appropriate denominators. RESULTS: Average annual incidence rates based on data from dermatologists were 97 per million overall, 74 for contact dermatitis and 14 for neoplasia. The corresponding rates for occupational physicians were 623 overall, 510 and 2, respectively. For infective disease, the rates for occupational physicians were 28 compared to 2 for dermatologists. Contact dermatitis was most frequently attributed to rubber chemicals, soaps and cleaners, wet work, nickel and acrylics; most cases of contact urticaria were attributed to rubber chemicals or foods and flour. The pattern of incidence rates by occupation and industry was complex, but correlated with the probable type of exposure. Rates of contact dermatitis were highest among skilled workers in the petrochemical and rubber and plastic manufacturing industries, with machine operators and technical workers in metal and automotive industries also at increased risk. High proportions of cases attributed to rubber chemicals were in nurses and technicians in the health and social services. CONCLUSIONS: These findings identify jobs and types of work where contact with causal agents is common and potentially preventable.     

Skin symptoms in bakery and auto body shop workers: associations with exposure and respiratory symptoms

Purpose

Despite the importance of skin exposure, studies of skin symptoms in relation to exposure and respiratory symptoms are rare. The goals of this study were to describe exposure–response relationships for skin symptoms, and to investigate associations between skin and respiratory symptoms in bakery and auto body shop workers.

Methods

Data from previous studies of bakery and auto body shop workers were analyzed. Average exposure estimates for wheat allergen and isocyanates were used. Generalized linear models were constructed to describe the relationships between exposure and skin symptoms, as well as between skin and respiratory symptoms.

Results

Data from 723 bakery and 473 auto body shop workers were analyzed. In total, 5.3 % of bakery and 6.1 % of auto body shop workers were female; subjects’ mean age was 39 and 38 years, respectively. Exposure–response relationships were observed in auto body shop workers for itchy or dry skin (PR 1.55, 95 % CI 1.2–2.0) and work-related itchy skin (PR 1.97, 95 % CI 1.2–3.3). A possible exposure–response relationship for work-related itchy skin in bakery workers did not reach statistical significance. In both groups, reporting skin symptoms was strongly and significantly associated with reporting respiratory symptoms, both work-related and non-work-related.

Conclusions

Exposure–response relationships were observed for skin symptoms in auto body shop workers. The lack of significant exposure–response associations in bakery workers should be interpreted cautiously. Workers who reported skin symptoms were up to four times more likely to report respiratory symptoms. Improved awareness of both skin and respiratory outcomes in exposed workers is needed.     

Shoe manufacturing and solvent exposure in northern Portugal

Shoe manufacturing is a traditional industry in northern Portugal. There are nearly 1500 factories that employ about 54,000 workers. Among the materials used in the shoe manufacturing process, that could be occupational hazards, are the adhesives, especially adhesives solutions based on organic solvents. The National Institute of Health (Oporto Branch) carried out a study of 100 factories in northern Portugal to study solvent exposure in shoe manufacturing. The surveyed population, (4615 workers) was young (mean age = 33 years; range = 18-45) and predominantly female (68.5%). The results from the air samples analyses show 20 different organic compounds existing in the workplaces. The more common compounds found were n-hexane, toluene, and acetone. The results of the study show that in 53.7 percent of the factories there are operations where the solvent exposure is significant and represents a health hazard to the workers. These operations are mainly gluing, waxing, and polishing stations. Occupational risk of exposure to solvents concerned 44.2 percent of the workers. This study points out the existence of inadequate ventilation in the workplaces and inappropriate personal protective equipment to prevent dermatitis risk from adhesives, wax, and polish. The organic solvents present in workplaces also increase fire risk.     

Perception and prevalence of work-related health hazards among health care workers in public health facilities in southern India

Background:

Health care workers (HCWs) are exposed to occupational related health hazards. Measuring worker perception and the prevalence of these hazards can help facilitate better risk management for HCWs, as these workers are envisaged to be the first point of contact, especially in resource poor settings.

Objective:

To describe the perception of occupational health hazards and self-reported exposure prevalence among HCWs in Southern India.

Methods:

We used cross sectional design with stratified random sampling of HCWs from different levels of health facilities and categories in a randomly selected district in Southern India. Data on perception and exposure prevalence were collected using a structured interview schedule developed by occupational health experts and administered by trained investigators.

Results:

A total of 482 HCWs participated. Thirty nine percent did not recognize work-related health hazards, but reported exposure to at least one hazard upon further probing. Among the 81·5% who reported exposure to biological hazard, 93·9% had direct skin contact with infectious materials. Among HCWs reporting needle stick injury, 70·5% had at least one in the previous three months. Ergonomic hazards included lifting heavy objects (42%) and standing for long hours (37%). Psychological hazards included negative feelings (20·3%) and verbal or physical abuse during work (20·5%).

Conclusion:

More than a third of HCWs failed to recognize work-related health hazards. Despite training in handling infectious materials, HCWs reported direct skin contact with infectious materials and needle stick injuries. Results indicate the need for training oriented toward behavioral change and provision of occupational health services.     

Contribution of occupational factors to social inequalities in self-reported health among French employees

Objectives

Social inequalities in health have been widely demonstrated. However, the mechanisms underlying these inequalities are not completely understood. The objective of the study was to examine the contribution of various types of occupational exposures to social inequalities in self-reported health (SRH).

Methods

The study population was based on a random sample of 3,463 men and 2,593 women of the population of employees in west central France (response rate: 85–90 %). Data were collected through a voluntary network of 110 occupational physicians in 2006–2007. Occupational factors included biomechanical, physical, chemical and psychosocial exposures. All occupational factors were collected by occupational physicians, except psychosocial work factors, which were measured using a self-administered questionnaire. Social position was measured using occupational groups.

Results

Strong social gradients were observed for a large number of occupational factors. Marked social gradients were also observed for SRH, manual workers and clerks/service workers being more likely to report poor health. After adjustment for occupational factors, social inequalities in SRH were substantially reduced by 76–134 % according to gender and occupational groups. The strongest impacts in reducing these inequalities were observed for biomechanical exposures and decision latitude. Differences in the contributing occupational factors were observed according to gender and occupational groups.

Conclusion

This study showed that poor working conditions contributed to explain social inequalities in SRH. It also provided elements for developing specific preventive actions for manual workers and clerks/service workers. Prevention towards reducing all occupational exposures may be useful to improve occupational health and also to reduce social inequalities in health.     

Occupational dermatitis and allergic respiratory diseases in Finnish metalworking machinists

AIM: To investigate the incidences and trends of occupational skin diseases (OSDs) and allergic respiratory diseases (ARDs) in machinists working in the fabrication of metal products. METHODS: Data from the Finnish Register of Occupational Diseases during 1992-2001 were analysed. Incidence rates for skin and respiratory diseases of machinists were calculated and compared to the total working population. The patients investigated at the Finnish Institute of Occupational Health in the same period were described in detail. RESULTS: A total of 279 dermatoses and 34 ARDs were reported. Skin diseases accounted for 27% of all occupational diseases. The incidences of the skin and respiratory diseases were 1.6 and 0.2 cases per 1000 person-years, respectively. This represents a 3-fold risk for getting an OSD compared to the total working population. The number of allergic contact dermatitis (ACD) increased 3-fold during the study period. The most common causes of ACD were metalworking fluids (MWFs) and their ingredients such as formaldehyde, ethanolamines and colophony. Eighty-five per cent of ARDs were asthmas. The commonest causes of asthma were metal dusts and fumes, epoxy resins and hardeners and MWFs and their components. CONCLUSIONS: Contact dermatitis is a common occupational health problem in metalworking machinists, whereas occupational respiratory disease is rare. Only a few specific chemicals in the metalworking have thus far been identified as respiratory allergens. Specific skin tests and inhalation challenge tests with MWFs and their ingredients are recommended if an OSD or a respiratory disease is suspected.     

Occupational dermatoses in composite production

In a plant that produces fiber-resin composite by impregnation of cellulose fibers with phenol-formaldehyde and melamine-formaldehyde resins, a new technique was introduced that resulted in problems in the handling of uncured products. Many workers suffered dermatitis on areas of exposed skin. A primary investigation found that some workers had an occupationally related skin disease with contact allergy to work materials. We undertook a survey of occupational dermatoses, based on a questionnaire, clinical examination, and patch test with a standard series and a series of products and chemicals representing the work environment. Eighty-eight workers participated in the clinical investigation. In six workers, contact allergy to phenol-formaldehyde resin was seen, and in five workers, contact allergy to melamine-formaldehyde resin was noted. Two workers were allergic to both resins. Occupational dermatitis was diagnosed in nine of 88 (10.2%) workers. In this article, we discuss possible preventive measures for avoiding occupational dermatitis.

Occupational relevance of positive standard patch-test results in employed persons with an initial report of an occupational skin disease

OBJECTIVES: It is commonly accepted that the standard screening tray is an essential diagnostic test in patch testing supporting the diagnosis of contact dermatitis, the most common type of occupational skin disease (OSD). In this study standard patch-test results of employed persons with an initial report of an OSD were analyzed within 24 occupational groups. METHODS: An evaluation was made of employed persons recorded in the Register of Occupational Skin Diseases in Northern Bavaria (Berufskrankheitenregister Haut-Nordbayern; BKH-N) between 1990 and 1999, catering for those standard screening tray allergens tested over the 10-year period. RESULTS: Nickel sulfate was the most common sensitizer (29.5%), showing occupational relevance in only 11% of the cases sensitized. Other common sensitizers were cobalt chloride (13.5%), p-phenylenediamine free base (10.7%), potassium dichromate (9.8%), fragrance mix (5.4%), thiuram mix (4.2%), balsam of Peru (4.0%), chloromethylisothiazolinone/methylisothiazolinone (4.0%), and formaldehyde (4.0%). The most occupationally relevant sensitizers were thiuram mix (71%), epoxy resin (67%), p-phenylenediamine free base (59%), p-phenylenediamine-black-rubber mix/ N-isopropyl- N'-phenyl- p-phenylenediamine (53%), potassium dichromate (48%), formaldehyde (38%), chloromethylisothiazolinone/methylisothiazolinone (37%), and mercapto-mix/mercaptobenzothiazole (35%). Occupational groups at risk of acquiring delayed-type sensitization were, in particular, electroplaters, tile setters and terrazzo workers, construction and cement workers, solderers, wood processors, and leather and fur processors. CONCLUSIONS: The standard series contributes valuable information and asserts its position in clarifying the causes of OSDs. Based on the study results, the rate of occupationally relevant sensitization to each single allergen is demonstrated, and the difficulties in verifying the occupational relevance are discussed.

Ten years incidence of natural rubber latex sensitization and symptoms in a prospective cohort of health care workers using non-powdered latex gloves 2000–2009

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.
