Hepatitis virus infection in flying airline personnel
Sera of 1126 flying personnel were tested for present or past infection with hepatitis B virus (HBV) or A virus (HAV). The prevalence of anti-HA antibodies was similar to that of controls. HBV immunity was similar in pilots, flight engineers, and female flight attendants, but more prevalent in male flight attendants. Within 1 year, 13 of 2624 personnel had acute hepatitis, mainly due to hepatitis B among male flight attendants. It is suggested that life style may be responsible for these findings.

Chickenpox outbreak in staff and students of a hospital in the tropics
12 members of the staff of a hospital in India acquired varicella from a young patient. None had had varicella earlier. In tropical hospitals with many non-immune staff it may be difficult to prevent hospital-acquired infection. Immigrant staff from the tropics working at hospitals in temperate countries are also at risk. Their immunity should be assessed so that measures can be taken to forestall varicella outbreaks in hospital personnel.

Result of a study of epidemic kerato-conjunctivitis (with adenovirus) in ophthalmological practice
Résultat d'une enquête sur les kérato-conjonctivites épidémiques (à adénovirus) en milieu ophtalmologique [en francés]
Results of a nationwide survey in France among ophthalmological services where the personnel seems at particularly high risk (230 cases reported, 108 of which were in medical staff, 86 in nursing staff and 36 in various other workers) due to the endemic nature of the disease transmitted by patients with infection occurring via the hands and medical instruments. This disease should be included in the schedule of occupational diseases.

Viral hepatitis in hospitals
Hépatites virales en milieu hospitalier [en francés]
Investigation in a hospital where the staff medical service physician made regular check-ups on the personnel over a period of 13 years: study of trends in hepatitis cases (distribution chronologically, and by hospital department); in-depth research on the types of hepatitis which occurred and immunity acquired by intensive-care unit personnel. The results of the investigation and available statistics show that the present-day practitioner is better acquainted with the helath status of hospital staff and is therefore more efficient as regards preventive medicine. Analysis of general hepatitis prevention in hospital services: systematic medical surveillance and individual prevention (medical examinations, laboratory tests, consultations, return to work). Review of immunological aspects of viral hepatitis.

State of the art regarding contagious diseases in occupational medicine: melioidosis, Legionaries' disease, African haemorrhagic viral diseases (Lassa, Marburg, Ebola)
Actualisation de maladies infectieuses en médecine du travail: mélioïdose, maladie des légionnaires, fièvres virales hémorragiques africaines (Lassa, Marburg, Ebola) [en francés]
This MD thesis considers 3 groups of contagious diseases of recent occurrence in our environment. Currently available data are used to determine if they can be linked to certain occupations, with consequent implications for occupational medicine, with a view to possible amendments to labour legislation. The thesis is mainly concerned with the ecological and epidemiological characteristics of these diseases, their clinical aspects, the occupations at risk, and case studies in the working environment. Prophylaxis is also considered.

Virus warts in meat handlers
Epidemiological study of virus warts on the hands of employees of a large meat processing factory (pork, beef). Of 1,141 employees examined, 687 were constantly handling meat. Detailed study of the various departments of the factory (deboning, butchery, processing, storage, packing, cookhouse, etc.). According to type of employment, prevalence of warts varied between 33.6% and 70.4% in employees handling meat, and between 18.2 and 44.4 in non-meat handlers. In 50% of these cases the workers concerned were unaware of the development of warts (especially plane warts).

Harmful occupational biological agents - Classification
Klasyfikacja biologicznych szkodliwości zawodowych [en polonés]
Description of a new system of classifying biological agents that may cause occupational diseases. The system comprises a classification based on the principles of taxonomy (from viruses to vertebrates) and a classification on the basis of workplace characteristics. The first gives data on 83 agents: Latin and Polish names, occurrence, means of transmission, routes of entry, effects on the human body and categories of workers exposed. In the second, the symbols adopted for the data on each agent are attributed to 208 workplaces, arranged by category of occupational and branch of industry. The classification, which also includes an appendix containing a descriptive list of methods for studying the workplace and for the periodic medical examination of workers, is intended to help in diagnosis, treatment and prevention.

Infectious liver diseases in three groups of Copenhagen workers: Correlation of hepatitis A infection to sewage exposure
3 groups of municipal workers, matched for age and duration of employment, and consisting of 77 sewer workers, 81 gardeners and 79 clerks were studied for clinical and serological evidence of infection with viral hepatitis types A and B and pathogenic leptospires. Antibody against hepatitis A virus (anti-HAV) was found in 80.5% sewer workers compared with 60.5% gardeners and 48.1% clerks. The anti-HAV prevalence rates correlated with age rather than duration of employment. In 11 reported cases of jaundice only 3 occurred amongst sewer workers. Hepatitis B serological markers were similar in each group. Exposure to metropolitan sewage appears to impose a limited risk of hepatitis A infection while the hepatitis B virus is not successfully transmitted by this route.

Hepatitis B in a medical center.
Over a 40-month period, there were 1,235 cases of exposure to blood product or body fluids. Of the 155 workers exposed to HBsAg-positive blood, 101 were not immune to hepatitis B. 3 of them developed clinical hepatitis, as did 24 other employees. The cumulative incidence was 106 per 100,000 employee-years.

Ornithosis in poultry workers.
An outbreak of ornithosis in duck workers is reported. A serological survey showed that 61% of them (compared with 23% of control workers) had chlamydia group antibody titres of ≥ 1:8. 9% of duck workers had antibody titres ≥ 1:32 and a clinical illness suggestive of ornithosis. The proportions of seropositive tests and clinical attack rates were highest in workers eviscerating ducks and lowest in farm workers.

The relation between length of service and the course and sequelae of viral hepatitis in workers in the chemical industry
O vlijanii professional'nogo staža na tečenie i posledstvija virusnogo gepatita u rabočih himičeskih predprijatij [en ruso]
Viral hepatitis occurs in a more severe and protracted form in workers who have been occupationally exposed to toxic chemicals for long periods. Liver functions are more extensively impaired. Where the disease remits, biochemical levels are slow to normalise. Greater length of service correlates with more harmful sequelae.

A prevalence study of virus warts on the hands in a poultry processing and packing station.
The prevalence of viral warts in these workers was 38.2% (11.9% in a control population of textile workers). The common human papova virus was identified from scrapings. The possible reasons for the high prevalence of warts is discussed: the cause may be that the workers' hands are frequently wet rather than contact with the chickens themselves. Wearing gloves significantly protected workers against warts, but the prevalence was still 32% in those who always wore gloves.

Viral infections in laboratory personnel.
The staff of the Indian National Institute of Virology was studied. Since the Institute was established in 1952, there have been 87 cases of infection with Kyasanur forest disease (KFD), 3 with Chikungunya, 7 with Ganjam and 1 with West Nile viruses. 64 of the KFD infections were in laboratory workers, 23 in field workers collecting insects. Infections were similar to natural cases, but there were no deaths in laboratory personnel. Vaccination with formolised KFD vaccine in 1966 seemed to reduce the incidence of infection in laboratory workers. The main mode of infection was via aerosols.

Hepatitis B: An occupational hazard of health care facilities.
During a 4 year period, 30 cases of hepatitis B attributed to work occurred at an urban medical centre. Only 5 of the workers affected described a relevant incident before onset of the disease. Early symptoms were non-specific, and routine monitoring and clinical awareness are necessary for early diagnosis. More effective control measures are needed. It is unlikely that post-exposure immune globulin prophylaxis will reduce the incidence of hepatitis B.

Recommendations for prophylaxis of viral hepatitis
Recommandations concernant la prophylaxie de l'hépatite virale. [en francés]
Paper communicated to the Technical Regional Committee for Food Wholesale and Retail Trades (Comité technique régional "alimentation-interprofessionnelle", Lille, France). The recommended prophylaxis consists essentially of general hygiene measures for hospital nursing, laboratory and haemodialysis unit personnel. These measures, designed to avoid contact with contaminated matter or linen, are listed. Screening for Australia antigen plays an important part in the prevention of this disease. The article mentions the role of passive immunisation by preventive injection of gamma globulin.

Hepatitis in undertakers.
106 undertakers were studied. The percentage who gave a past history of hepatitis was no greater than that of controls. There was a non-significant difference in the number with blood that was positive for antibody to hepatitis B surface antigen. While undertakers appear to be in a low-risk occupation as regards hepatitis, it is suggested that there may be an increased risk of exposure in undertakers who do not wear gloves, and this practice is therefore recommended.

Occupational disease during pregnancy and its effects on the foetus
Les maladies professionnelles chez la femme enceinte et leur retentissement sur le f¿tus. [en francés]
MD thesis. Considerations on teratogenesis and ways in which the ovum can be harmed are followed by a review of the various pathogenic agencies to which a female worker could be occupationally exposed during pregnancy: physical (mechanically-caused trauma, whole-body vibration, ultrasound, effects of hot workplaces, ionising radiation); infectious, viral or chemical (benzene, lead, mercury, arsenic, cadmium, pesticides, etc.), indicating the particular hazards of each. The author then refers to French labour legislation as it applies to pregnancy during employment, emphasising the role of the plant physician, who is in the best position to assess the hazards to which an expectant mother is exposed if she continues in her employment.

Accidents in general hospital laboratories
Les accidents dans les laboratoires des hôpitaux généraux. [en francés]
Results of a study of the frequency and severity of occupational accidents and diseases in the personnel of non-university hospitals in France from 1970 to 1974. Infectious diseases head the list (9.9% of workers). The most frequent is viral hepatitis (6.5%), occurring especially in biochemical laboratories in proportion to the number of examinations performed. This is followed by tuberculosis (1.8%); overcrowding of the laboratories and the small space allotted to laboratory staff appear to play a role in transmission of the disease. Comparison with other studies. Preventive measures.

Hazards of women occupationally exposed to rubella - Occupational health problems and compensation
Risques encourus par les femmes professionnellement exposées à la rubéole - Problèmes posés par la prévention et la réparation. [en francés]
MD thesis. Study of the problem of pregnant women occupationally exposed to rubella, with the concomitant hazard of foetal abnormality (employment in laboratories, hospitals, educational establishments, kindergartens, creches and nurseries, social welfare work, etc.). Contents: brief overview of rubella infection and its prevention, epidemiology, diagnostic methods, study of congenital rubella, prevention. Preventive measures consist mainly of serum prophylaxis (which has contraindications). Situation in some countries (USA, Belgium, Switzerland) as regards vaccination. In France, the question of screening high-risk populations (female employees of hospitals and educational establishments) for rubella antibodies, with vaccination of serum-negative subjects, is under consideration. Role of the occupational health physician and responsibility of the State towards exposed persons. An amendment to the statutory lists of occupational diseases giving entitlement to compensation is proposed.

Antagonistic activity of poly(4-vinylpyridine-N-oxide) to the inhibition of viral interferon induction by asbestos fibres.
The depressive effect of various asbestos fibres on interferon induction by influenza virus was significantly diminished or abolished by pretreating either the asbestos fibres or cell monolayers with poly(4-vinylpyridine-N-oxide). Maximum antagonistic activity was time- and concentration-dependent. Pretreating asbestos fibres with the polymer was more rapid and effective than pretreating cell monolayers.

Hepatitis among plasma fractionation workers - An industry-wide study.
This questionnaire and field study covered 14 plasma-processing plants. Inspection revealed many instances of employee-product contact throughout the process (reception, pooling, centrifugation, leophilisation, recovery of the powder (harvesting), filtration, bottling). Awareness of the hazards was very poor. Epidemiological data on 86 clinical cases of viral hepatitis are given and discussed. Plasma fractionation is a high-risk vocation, and several questions as to protection remain unanswered.

Hepatitis B virus infection in dental surgical practice.
61 dental surgeons were interviewed. 6 had a history of hepatitis. The results of serological studies are given and discussed. Dental surgeons may be more at risk from hepatitis B infection than the general population: use of sharp instruments in a field contamined with saliva and possibly blood, potentially infectious aerosol projected by ultrasonic rotary instruments and air and water sprays. While hospital dental surgeons may be particularly vulnerable, they can take appropriate precautions if the HBsAg status of the patients is known. In the present study the infection rate in hospital dentists was low. Measures recommended: medical history, emphasising hepatitis, blood transfusion or drug abuse; referral of suspected cases for blood testing; use of mask and gloves when treating HBsAg-positive patients; injection of hepatitis B immunoglobulin if the skin is punctured and contaminated with potentially HBsAg-positive material.

Relation of e antigen to infectivity of HBsAg-positive inoculations among medical personnel.
Accidental inoculation of blood containing hepatitis-B surface antigen (HBsAg) resulted in hepatitis B or an anti-HBs response in 60% of cases when e antigen was present, as against 31% when it was not. A soluble protein identified by Magnium and Espmark in sera containing HBsAg, e antigen appears to be a marker of infectivity in maternal-foetal transmission of hepatitis B. The high prevalence of e antigen in patients on renal dialysis units where staff acquired hepatitis B most frequently suggests a comparable association. e antigen was detected in 74% of inocula from chronic renal dialysis and transplantation units, compared with 28% from other services, and the incidence of hepatitis B varied accordingly (22% and 6%, respectively). The validity of linking e antigen with infectivity is briefly discussed.

Immunisation against hepatitis B in man.
An inactivated vaccine against hepatitis B (serum hepatitis) was administered to 96 people at a hospital in Tours (France). Results in 46 of them (mainly members of the ward staff or relatives of dialysis patients) are reported. A positive response - production of anti-HBs antibodies - was elicited in 35. The vaccine appears to protect against hepatitis B. A general outline of some of the difficulties encountered in developing a vaccine are published in the same issue of Lancet (Zuckerman A.J., p.1396-1397, 20 ref.), together with a general commentary of the question (p.1391).

Isolation of swine influenza virus from autopsy lung tissue of man
Case report of a boy who until 5 days before his death from respiratory failure due to Hodgkin's disease had worked on a farm where swine were raised. Swine influenza virus was isolated from lung specimens at autopsy. The possibility that both the Hodgkin's disease, and the chemotherapy for it, had modified his resistance to infection by impairing immunological responses is discussed.

Incidence of tuberculosis, hepatitis, brucellosis, and shigellosis in British medical laboratory workers.
A retrospective questionnaire survey of 21,000 medical laboratory workers in England and Wales in 1971, and of 3,000 in Scotland in 1973, showed: 21 new cases of tuberculosis (5 times the rate in the general population), 38 cases of hepatitis, 45 cases of shigellosis (microbiology staff were twice as vulnerable as that of other pathology divisions), and one case of brucellosis. Tuberculosis definitely, and hepatitis and shigellosis possible, are still occupational hazards of British medical laboratory workers.

Pathologie rurale. [en francés]
Review of the various health hazards commonly encountered in the rural milieu: a) poisoning due to the natural environment (animals and plants), or to the use of products such as fertilisers and pesticides, or due to other factors (carbon monoxide, lubricants, solvents, etc.); b) disease due to infection by parasites or pathogenic agents, with increased incidence due to modern farming methods (zoonoses, tetanus, anthrax, rabies, etc.); c) pathology of accidents (due to a wide variety of causes: animals, use of machinery, etc.); d) physiopathology and pathology linked to mechanisation (tractors, use of aircraft in agriculture etc.); e) pathology linked to various factors (bad weather, dust, noise and vibrations, bad posture, eating habits, fatigue, etc.). For each pathological cause the appropriate preventive measures and the essential statutory provisions which apply are indicated. List of French bodies concerned with occupational safety and health in rural occupations. List of relevant French regulations.

Hepatitis B virus infection in dentists.
Of 1,245 dentists, 0.9% were positive for hepatitis B surface antigen, and 12.7% were antibody positive. The frequency of evidence for infection increased with increasing years of professional experience. Dentists appear to have a risk of hepatitis B virus infection about 2-3 times that of the general population. Frequencies did not vary with geographic region in the USA, nor with size of community.

Laboratory-acquired hepatitis B.
Letter to the editor proposing a method to overcome the high risk of hepatitis when Coombs test material is transferred from test tubes to slides for microscopic reading. An inversion microscope equipped with a viewing holder for 10x75mm tubes is used, allowing agglutination patterns to be directly assessed in the tube, so avoiding transfer of hazardous material. Visual assessment is considered as accurate as the traditional slide and pipette method, and the cost of the microscope is quickly recovered in savings due to the fact that additional slides and pipettes are not required.

Human psittacosis associated with commercial processing of turkeys.
After an introduction tracing the incidence of psittacosis epidemics in the USA, this report describes investigations of a series of such epidemics at turkey-processing plants, mainly in Texas, in May-Aug. 1974, involving 114 workers. The incidence in 80 workers at 3 plants is classified by occupation: the attack rate was directly related to exposure to the viscera and faeces of infected turkeys. Workers exposed to live birds did not fall ill. Serological studies suggested that non-clinical psittacosis may be relatively common in persons associated with turkeys. Control measures included screening turkey flocks before slaughter and treatment of infected birds.

Hepatitis B immune globulin - Prevention of hepatitis from accidental exposure among medical personnel.
Less than 1% of medical workers who were anti-HBs-positive developed hepatitis, against 11% of anti-HBs-negative subjects. Trials were performed with immune-serum globulin preparations of varying titres. The incidence of hepatitis in groups passively immunised with globulin having a titre of 1:50, 1:5,000 and 1:500,000, respectively, was 7, 5, and 2%. The significantly lower incidence in the last group (p<0.25) was offset by additional cases found at follow-up after 9 months. Various psssible explanations of this delayed onset are put forward.
