Beedi industry - Working for solutions
This article describes a survey carried out in the beedi industry in the city of Gwalior, India. The 75 respondents were all women, of average age 36 (13 to 75), having worked in the sector for an average of 14 years. Four suffered from asthma, 17 from chest pain and three from tuberculosis. All complained of breathlessness. Earlier studies report frequent miscarriages among women beedi workers due to the continuous squatting posture. Workers were found to have minimal awareness of their rights. Several recommendations are made for improving occupational health in this sector.

CIS 02-940 Sero-prevalence of Borrelia burgdorferi among Flemish forestry workers
Seroprevalentie van Borrelia burgorferi bij Vlaamse bosarbeiders [in Dutch]
The number of registered cases of Lyme disease has been increasing each year in Belgium. To evaluate the impact of Lyme disease among forest workers, a sero-prevalence study was conducted in 1996, involving 261 employees of the forestry department of the Flemish community. The aim of the study was to evaluate the prevalence of antibodies against Borrelia burgdorferi responsible for Lyme disease. The frequency of tick bites in the past year and the extent of self-reported symptoms of employees Lyme disease were also noted. It was found that 9% of the investigated population had a positive serology (IgM or lgG antibodies measured by ELISA and immunofluorescence) for B. burgdorferi.The forestry workers reported an average of 17 tick bites per year. The highest levels were reported in the provinces of Limburg, Antwerp and Flemish Brabant. 13% of the employees retrospectively reported a skin rash which resembled erythema chronicum migrans (ECM). This study showed that the risk of Lyme disease is real and correlates with the high degree of exposure.

Abnormal liver function associated with occupational exposure to dimethylformamide and hepatitis B virus
N,N-Dimethylformamide (DMF) has excellent solvent properties and is used intensively in the production of synthetic leather and resins. It has caused hepatoxicity in human and animal studies. Hepatitis B virus (HBV) and hepatitis C virus infections are reported to be the major causes of chronic liver diseases (including liver cirrhosis and liver cancer) in Taiwan. This study examined the dose-response relationship of the observed abnormal liver function among the DMF-exposed workers and the interactions among DMF, other chemical exposures, HBV infection, and potential confounders on liver abnormalities. It was observed that a significant dose-response relationship existed between liver function abnormalities and DMF exposure among workers in Taiwan, and that HBV carrier status or increased BMI had synergistic effects with DMF exposure in causing liver abnormalities (abnormal liver function tests and clinical chronic liver diseases).

Unheard voices of silicosis affected people in Lalkuan, Delhi
This article presents the results of a survey conducted in a suburb of New Delhi (India), where an important stone-crushing activity had taken place for over 40 years. The purpose was to identify persons who were affected by silicosis or silico-tuberculosis. 146 persons were interviewed, of whom 83 were suspected to be affected on the basis of their symptoms and occupational history. Information was also collected from families of persons who had died from these affections. It is hoped that the survey will give rise to increased awareness of silicosis as an occupational disease.

Radiological progression and its predictive risk factors in silicosis
141 patients with silicosis contracted from granite work with available serial chest X-ray films of acceptable quality taken over a period of 2 to 17 years were selected for study. 94 had ended exposure at least 5 years earlier. Radiological progression was assessed by paired comparison of the initial and most recent radiographs. Overall, 37% of patients had radiological evidence of progression. As expected, progression was more likely to be found after longer periods of follow up (the interval between the two chest X-ray films) with a 20% increased odds of progression for every additional year of follow up. After adjustment for varying intervals of follow up, the probability of radiological progression was found to be significant if large opacities were present in the initial chest X-ray film. Progression was also less likely to be found among those who had ended exposure to silica earlier. Tuberculosis was also associated with increased likelihood of progression.

Predicting the ultraviolet radiation distribution in a room with multilouvered germicidal fixtures
A relatively inexpensive method to reduce transmission of airborne infectious diseases, such as tuberculosis, consists in irradiating the upper part of a room with ultraviolet (UV) radiation. To obtain a protection of workers in the lower part of a room from radiation, multilouvered UV germicidal fixtures, producing a horizontal beam, are used. In this article, a model is developed to predict the UV fluence rate at any location in the upper room for such fixtures and also total UV power emitted by the same.

Legionnaires' disease - A guide for employers
Legionnaire's disease is a potentially-fatal pneumonia caused by Legionella bacteria. Legionella are widespread in the environment, and may grow in cooling towers and hot and cold water distribution circuits. They survive low temperatures and thrive at temperatures between 20°C and 45°C in presence of nutrients such as rust, sludge, scale, algae or other bacteria. Aimed at employers, this booklet outlines the steps they need to take in order to fulfil their legal responsibilities against the risk of legionnaire's disease at the place of work. In particular, these steps include conducting a risk assessment, implementing preventive measures and keeping records.

CIS 09-106 Patterns of ill-health in Irish construction workers
In the Irish construction industry, data on illness and injury resulting in absenteeism or permanent disabilities leading to early retirement were not known. The objectives of the research were to establish these data, and to develop a database to contribute to define health promotion policies for the sector. The population base for the study comprised construction workers who were members of the Construction Federation Operatives Pension and Sick Pay Scheme. Over 29,000 records of absences of more than three days duration in the 16 year period from 1981 to 1996 were examined. There was an annual average of 7.8 absences per 100 workers due to injury or illness, the mean length of absence being 23.5 working days. Findings include the main diseases, age-linked differences, causes of invalidity and causes of early retirement.

Prevalence of cytomegalovirus infection among health care workers in pediatric and immunosuppressed adult units
The objective of this study was assess the prevalence of cytomegalovirus (CMV) infection among health care personnel working with children and immunosuppressed patients. The study involved a clinical examination, a medical and occupational questionnaire, the assessment of tasks performed, and CMV serologic testing of 400 female health care workers. Overall seroprevalence was 44.25%. Prevalence differed significantly with age and parity (number of children) and was higher among personnel who worked in closer contact with the patients (nurse's aides) than among those whose tasks required more technical skills (nurses), 57.3% vs. 34.5%. Logistic regression analysis between prevalence of CMV antibodies, age, parity and type of job showed that contact with patients was as significant a factor as parity.

Antiretroviral prophylaxis of health care workers at two urban medical centers
This study examined the influence of job category, source patient HIV status and exposure type on whether health care workers initiated antiretroviral prophylaxis after potential blood-borne pathogen exposures. Of 639 exposures over an 18-month period, 82 individuals (13%) elected to receive prophylaxis, of whom 66% took medications for fewer than 96 hours and only 12% completed a 4-week course. Reasons for early drug discontinuation included confirmation of source patient HIV negative serological status (65%), gastrointestinal side effects (13%), headache (4%), and personal decision after counseling or other inputs (18%). Individuals exposed to HIV-positive source patients were more likely to initiate prophylaxis (odds ratio (OR), 5.1). Licensed nurses were less likely than others to accept prophylaxis (OR 0.5), whereas physicians and medical students were more likely to accept prophylaxis (OR 1.9).

Rickettsiosis in Sicily and mass media: A not entirely groundless attention
Rickettsiosi in Sicilia e mezzi di comunicazione di massa: attenzione non del tutto immotivata [in Italian]
The prevalence of rickettsial diseases was assessed in Sicily (Italy) with special attention to possible occupational exposure, due to a high number of cases reported in the press. Epidemiological data showed that Sicily was indeed the Italian region where most cases of rickettsiosis occurred. Analysis of the clinical data showed that an occupational risk existed among small farmers, and that there was also a risk for other subjects active in rural areas, due to contact with infected dogs.

Regulating the risk of tuberculosis transmission among health care workers
The relationship between tuberculosis (TB) infection and disease rates is discussed, and a probability framework is introduced for the apportioning of the infection risk between occupational and non-occupational exposure. It is argued that most TB infections among health care workers are work-related. A 0.2% overall annual risk of TB infection is proposed as acceptable, because in the context of an infection surveillance programme it limits the cumulative disease risk faced by health care workers close to the value for the general United States population. Based on the probability framework, an estimate of the background community infection rate and the traditional Wells-Riley risk model it is shown that a target workplace infection risk value can be derived and applied to risk management decision making.

Mycobacterial contamination of metalworking fluids: Involvement of a possible new taxon of rapidly growing mycobacteria
Contamination of air and metalworking fluid (MWF) systems by a rapidly growing mycobacterium (RGM) was detected in a manufacturing plant with recent cases of hypersensitivity pneumonitis (HP). Environmental sampling was performed to determine the extent of the contamination and its variability over time. RGM were present in multiple indoor air samples, central MWF storage tanks, and cutting, drilling, and grinding machines. Contamination was essentially limited to a formulation of semi-synthetic MWF recently introduced in the plant. In general, the mycobacterial counts were stable over time, with the degree of contamination ranging from 102-107 colony forming units/mL. Using molecular techniques, it was found that the mycobacterial isolates consisted of a single strain and represented a previously undescribed taxon closely related to Mycobacterium chelonae/abscessus. The relationship of this mycobacterium to the cases of HP remains unknown.

DDT and its derivatives
At very high concentrations, DDT has been shown to mimic the effect of sexual hormones in vitro. This has been confirmed for very high dosages in animal studies. However, existing studies in humans show no correlation between DDT contamination and adverse effects subject to hormonal influences. The association between DDT contaminations and breast cancer has been studied in several epidemiological studies but cannot be confirmed on the whole. In most developed countries, DDT use has been discontinued. The study did not discuss the question of possible consequences from persistent use of DDT in certain developing regions of the world, for example for fighting malaria.

Occupational risk of infection by varicella zoster virus in Belgian healthcare workers: A seroprevalence study
The presence of varicella zoster virus (VZV, chickenpox) antibodies was investigated in health care personnel in Belgian hospitals. The prevalence of VZV seropositivity was 98.5%. Seronegative workers were significantly fewer among nursing than among non-nursing staff. Because of this low overall susceptibility, VZV infection seems not to be an important occupational risk among healthcare workers. A negative history of chickenpox had no value as a predictor of susceptibility in adults.

Sickness absence and early retirement on health grounds in the construction industry in Ireland
Records of sickness absence among construction workers in Ireland since 1981 were analysed. The mean annual absence rate was 7.8/100 workers. Three quarters of the absences were among younger workers; however, the rate of absence and the mean duration of it increased with age. Injury was the most frequent reason for absence, followed by infectious disease and musculoskeletal disorders. The mean annual rate of early retirement on health grounds was 5.3/1000 workers. The median age at retirement was 58 years. Cardiovascular disease and musculoskeletal disorders accounted for nearly one third of the conditions leading to permanent disability.

Leptospirosis vaccine - Pharmacosurveillance survey carried out among doctors who administer the vaccination
Vaccin leptospires - Enquête de pharmacosurveillance auprès des médecins vaccinateurs [in French]
Leptosirosis consists of a bacterial infection which may be particularly serious and possibly fatal. It is transmitted to man by rats, through sludge or contaminated water, and is recognized as an occupational disease. The main risk populations include workers in waste disposal, waste water treatment, roadwork, maintenance and inspection of sewers, and analytical laboratories. This article presents the results of a survey of occupational physicians, aimed at establishing current practices in medical inspection, frequency rates of leptospirosis and the effectiveness of vaccination. Preventive vaccination is shown to be a useful way of fighting leptospirosis.

Risks of infection in medical laboratories
Risques infectieux dans les laboratoires d'analyses médicales [in French]
Despite the fact that each day, a large number of potentially contaminating samples are handled in medical laboratories, data on the risks of infection are still scanty. A first study was conducted in 1996 in 26 medical laboratories belonging to five hospitals, with the objective of collecting the basic data necessary for hazard evaluation (see CIS 98-954). The study carried out two years later in the same laboratories enabled the assessment of trends with respect to approaches and risk perception.

Comparative study of the HAV seroprevalence among water purification station workers, sewage workers and administration workers
Enquête comparative de séro-prévalence de l'hépatite A entre les professionnels d'une station d'épuration, de l'assainissement et administratifs [in French]
An HAV seroprevalence study was conducted among 390 water-purification station workers, 201 sewage workers, and 643 non-occupationally exposed administrative workers. All workers were male, with similar age and socio-educational characteristics. After correcting for age, the rate of hepatitis A seroconversion for all populations was about 69%. Occupational exposure to sludge and sewage were the most important transmission risk factors for hepatitis A. Water-purification station workers exposed to soiled earth polluted with sludge were subject to major risk of hepatitis A transmission with an odds ratio of 1.85. For sewage workers, contact with floating corpses appeared to be an increasing occupational risk for hepatitis A, with an odds ratio of 1.59. A multivariate analysis was also performed to determine the characteristics of the exposed groups and evidence certain patterns of hepatitis A exposure. Vaccination against hepatitis A appears to be the best way to fight against this biological risk, although hygiene and safety measures must not be overlooked.

Risk factors for Nipah virus infection among abattoir workers in Singapore
During 10-19 March 1999, 11 workers in one of two Singapore abattoirs developed Nipah-virus-associated encephalitis or pneumonia, resulting in one death. A case-control study was conducted to determine occupational risk factors for infection. Case patients were workers from the affected abattoir who had anti-Nipah IgM antibodies; control subjects were randomly selected workers from the same abattoir who tested negative for anti-Nipah IgM. All 13 case patients versus 26 (63%) of 41 control subjects reported contact with live pigs. No unusual illnesses among pigs processed during February-March were reported. Contact with live pigs appeared to be the most important risk factor for human Nipah virus infection. In the other abattoir where no case was reported, the use of face shields increased among eviscerators 3-4 months before the outbreak. Direct contact with live, potentially infected pigs should be minimized to prevent transmission of this potentially fatal zoonosis to humans.

Job-related travel abroad: What demands, what answers?
Déplacements professionnels à l'étranger: quelles exigences, quelles réponses? [in French]
With the globalization of markets, an ever increasing number of companies need to send their employees abroad for short or long periods, often to parts of the world with serious health risks. In such cases, the occupational physician is often consulted for the prevention of travel-linked diseases. His or her role is to inform and advise the employee about to embark on a trip, depending on the risks linked to the assignment (destination country, living conditions, length of stay). The occupational physician has access to numerous sources of information, in particular the medical press, information systems and the Internet.

Silicosis and tuberculosis: A proposed radiographic classification of tuberculosis to accompany the ILO international classification of radiographs of pneumoconioses
A significant proportion of workers exposed to silica dust are at risk of developing tuberculosis (TB). The higher the International Labour Organization (ILO) category of silicosis, the greater the TB risk. Subtle radiographic presentations of TB may be the initial manifestation of TB, particularly in the absence of sputum identification of TB bacilli. A proposed TB X-ray-reading form in addition to the ILO categorization of silicosis is offered. The implementation of a standardized TB X-ray reading approach should enable the detection of indolent TB lesions.

Survival of infectious Pseudomonas aeruginosa genotypes in occupational saturation diving environment and the significance of these genotypes for recurrent skin infections
Occupational saturation divers suffer from various skin disorders, of which skin infections are the most serious and frequent. Pseudomonas aeruginosa is the microbe most often isolated. P.aeruginosa isolates from 292 skin infections in operational saturation divers and about 800 isolates from occupational saturation diving systems have been collected during the period 1986 to 1998. 472 P.aeruginosa isolates have been genetically analyzed, of which 181 originate from skin infections in divers. 97 different P.aeruginosa genotypes have been defined. Some of these genotypes are solely found from skin infections, some solely from the saturation environment and about 25% were found both from infections and from the saturation environment. Eight frequent infectious genotypes are shown to be present over several years, both in infections and in the saturation environment. The study suggests that skin infections in occupational saturation divers are commonly caused by environmental strains and not by diver-to-diver contagion.

Transmission of Mycobacterium tuberculosis from medical waste; Further adventures of the tubercle bacillus
Three cases of pulmonary tuberculosis (TB) were reported among workers at a medical waste treatment facility in 1997. The facility accepted contaminated medical waste where it was shredded, blown, compacted and finally deactivated. There was no previous documentation of Mycobacterium tuberculosis transmission as a result of processing medical waste. The three patient-workers' isolates had different DNA fingerprints. One worker had a multidrug-resistant tuberculosis. Equipment failures, insufficient employee training and respiratory protective equipment inadequacies were identified at the facility. It is concluded that the processing of contaminated medical waste resulted in transmission of M. tuberculosis to at least one medical waste treatment facility worker. The issue of the journal also contains an editorial article (by Sepkowitz K.A.) on the worldwide resurgence of TB.

Dermatologic disease: Twenty-two year experience at the USAF aeromedical consultation service and review of other military and civilian experiences
The Aeromedical Consultation Service (ACS) is a U.S. Air Force tertiary referral service which evaluates aviators with complex medical problems and makes recommendations for their aeromedical disposition. This study reports the experience with dermatologic disease among aviators referred to the ACS over a 22-year period from 1975-1997. Fungal diseases were seen most frequently (14.5%). Five aviators were permanently disqualified from flying duties due to chronic urticaria. A review of other military and civilian experiences with dermatologic disease is also presented.

Prevalence of antibody to hepatitis A virus in drinking water workers and wastewater workers in Texas from 1996 to 1997
To determine if wastewater workers had a higher prevalence of antibody to hepatitis A virus (anti-HAV) than drinking-water workers, 359 wastewater and 89 drinking-water workers were evaluated for risk factors by questionnaire and tested for anti-HAV. Anti-HAV positivity was 28.4% for wastewater and 23.6% for drinking-water workers. After adjustment for age, educational attainment and Hispanic ethnicity, the odds ratio for the association between anti-HAV positivity and wastewater industry employment was 2.0. Among wastewater workers, never eating in a lunchroom, ≥8 years in the waste water industry, never wearing face protection, and skin contact with sewage at least once per day were all significantly associated with anti-HAV positivity. Wastewater workers had a higher prevalence of anti-HAV than drinking-water workers, which suggested that wastewater workers may have been at increased risk of occupationally acquired hepatitis A.
