The neutrophil function and infectious diseases in workers occupationally exposed to organochloride insecticides
Polymorphonuclear leukocyte (PMN) function was studied in 33 workers exposed to DDT. There was a severe impairment of chemotaxis, adhesive properties, phagocytosis and nitroblue tetrazolium dye reduction, and an increase in random and stimulated migration. Mechanisms are discussed. At the time of the survey there was a prevalence of infectious diseases - especially tonsillitis, pharyngitis and bronchitis - among the workers (significance compared with a control group of 1000 people: p<0.001); the incidence was significantly higher in workers exposed for 12-30 years than in those exposed for 3-5 years.

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.

Q fever hazards from sheep and goats used in research
Data are reviewed in an effort to delineate hazards to humans from small ruminants used in research. Prevalence of Q fever antibodies was 24% among 2097 sheep and 57% among 1475 goats from various sources. In a research facility using sheep, in which an epidemic of human Q fever occurred, antibody prevalence in sheep was 77%, with a large proportion of high titres. Antibody prevalence was 11% among 347 persons at 3 research institutes, mainly among students: prevalence among research staff, except for animal caretakers routinely exposed to sheep, approximated the prevalence in the general population.

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.

Effects of beclomethasone exposure in industry
Men and women engaged in production of aerosols of beclomethasone dipropionate (BDP), a potent corticosteroid, were studied. Marked vasoconstriction with subsequent rebound vasodilation and opportunistic mycosis (pityriasis versicolor, pharyngeal candidosis) were observed. There were no systemic effects. Improvement of the extraction system reduced air steroid levels from 14 to 0.2µg/m3, and there was a 4-fold drop in the number of skin swabs positive for BDP.

Nosocomial tuberculosis
The rate of skin test conversion was determined for hospital staff exposed to a smear-negative, culture-positive patient in respiratory intensive care unit. The patient required bronchoscopy, intubation and assisted ventilation. 31% of susceptible, exposed nurses converted their PPD skin test and, of this group, 10 were present at the time of bronchoscopy. During the bronchoscopy the case generated 249 infectious units per hour which resulted in 1 infectious unit of tuberculosis in each 68.9 cu.ft.(2m3) of air. Improved ventilation, high efficiency filters and ultraviolet irradiation are recommended for air cleaning.

Laboratory outbreak of Q fever acquired from sheep
91 staff working in a university department in which gravid sheep were used for foetal respiratory studies, were examined after an outbreak of Q fever. Of these, 28 had complement-fixing antibodies to the phase II antigen of Coxiella burnetii in their serum. Symptoms compatible with C. burnetii infection occurred in 14 of these patients. Symtomatic infections were related to the delivery of twin foetuses in one laboratory, and some evidence of infection was apparent in workers in other parts of the building. Subjects with serological evidence of infection were treated with tetracycline for 4 weeks.

Use of thermography for diagnosis of vascular diseases of the lower extremities
Primenenie teplovidenija dlja diagnostiki sosudistyh zabolevanij nižnih konečnostej [en ruso]
A Rubin-2 thermography device was used to study the infrared emission of the lower extremities of 50 experienced coalminers and of 12 controls. Criteria for visual analysis of thermograms were developed. A sharp drop in thermal emission and a thermal assymmetry of the lower extremities, typical of angiopathy, were observed in most of the miners. The observed angiopathy is probably due to the environmental conditions to which the miners are exposed, especially a combination of high temperature (19-28°C) and high relative humidity (90-95%). Reduced circulation in the lower leg and foot is a contributing factor to the eczema and mycosis which are chronic problems of miners.

Of 558 medical workers examined and/or treated, 92% had allergic reactions of the skin, upper respiratory tract or bronchi - most frequently dermatitis, eczema, or rash. The reactions occurred mainly in persons with many years of service. Patch testing of 100 subjects showed extensive allergy to common antibiotics, anaesthetics and group-B vitamins. Sinusitis, rhinitis, bronchitis and asthma occurrred, most often in response to penicillin and streptomycin. Some subjects with high sensitivity to 2-3 antigens (penicillin, streptomycin and Candida antigen) had a toxic-allergic myocarditis. 153 of the 558 subjects had candidiasis of the respiratory, genito-urinary and/or intestinal tract(s). Absorption through the skin and inhalation appeared to be the major routes of exposure to drugs. Improved ventilation, technical changes in certain procedures and frequent clinical examination of medical workers are recommended.

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.

Leptospirosis in trout farmers
5 cases of leptospirosis, ranging in severity from an influenza-like illness to a fatality, are documented. Leptospiral antibodies were found in these workers. Pond water or trout food contaminated with rat urine is believed to have caused the outbreak. An additional case, at a different location, resulted from a fish farmer wading in rat polluted water with defective rubber boots.

Endemic Tinea microsporica in persons employed in the industrial production of ornamental plants
Endemische Tinea microsporica bei Beschäftigen in der industriemässigen Produktion von Zierpflanzen [en alemán]
Report of 33 cases of Tinea microsporica due to Microsporum gypseum in gardeners in contact with glasshouse compost. The course of the disease often differed from the known clinical picture of tinea. It was possible to detect the pathogenic agent in cultures in spite of minimal efflorescence.

Effect of hydrogen sulfide on bacterial inactivation in the rat lung
Rats were exposed to 45ppm hydrogen sulfide (H2S) (TLV 10ppm) for 4 or 6h, and a significant reduction in the inactivation of viable staphylococci deposited in the lungs during a bacterial aerosol challenge was observed. Pre-exposure of rats to 46ppm H2S for 2h did not alter intrapulmonary staphylococcal inactivation. The impairment of the alveolar macrophage may account for this effect.

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.

Occupational factors in coccidioidomycosis.
Inhalation of the arthrospores of Coccidioides immitis in dusty occupations and laboratory environments can cause pulmonary coccidioidomycosis. The disease has occurred amongst agricultural workers, military personnel, workers involved in excavation and laboratory and hospital workers in the semi-arid regions of the south-western and western United States. Fomite transmission of the spores in cotton waste, and primary cutaneous coccidioidomycosis due to accidental inoculation, have also been reported. The incidence and severity of occupational coccidioidomycosis can be reduced by dust control measures and laboratory procedures.

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.

Prevention strategies in hospital occupational medicine.
The forces discouraging the development of preventive services for hospital workers are reviewed, and the occupational hazards in the hospital environment discussed: accidents; infections; toxicological hazards; stress. A preventive programme for hospital workers must consider the population at risk and the occupational hazards to which it is exposed; identify specific risks and provide methods of monitoring them; keep accurate records; analyse data at periodic intervals to determine and revise policies. The basic elements of the programme are: the pre-placement examination; reporting and monitoring systems; health education.
