An influenza-like illness appeared recently among workers in a plant processing synthetic yarn. A humidifier, a cold-water spraying system, was the suspected cause. Lung function changes over the day and week and changes in blood leucocytes were studied among the workers from the suspected
Following its relatively recent birth in the 1700s from the pioneering work of Dr. Bernardino Ramazzini, occupational medicine has grown to encompass an array of respiratory conditions. One such condition is byssinosis, a collection of respiratory symptoms elicited by exposure to raw non-synthetic
On the basis of some study results in China and reports from abroad, a conclusion should be drawn that leads to the recognition of a pneumoconiosis-like lesion of interstitial fibrosis. This disease is called "cotton pneumoconiosis" and we may classify these occupational lesions into four types: 1)
The features of the cotton dust syndrome which need to be considered when formulating a hypothesis on mechanism(s) are: 1) the presence of fever, 2) the "Monday effect," 3) the slow onset of forced expiratory volume in 1 second (FEV1) changes, and 4) the presence of bronchitis in chronic sufferers
The Clinica del Lavoro of Milan provided several contributions to industrial hygiene and occupational toxicology during the twentieth century.Describe the first years of the laboratory of industrial hygiene of Milan through three figures who played a
Respiratory histories and preshift and postshift spirometry were recorded for 90 cotton felt workers and 54 brick workers. Environmental monitoring included area sampling by vertical elutriator and cyclone and personal sampling for respirable dust by cyclone. The prevalence of mill fever and
Experiments were performed to evaluate the in vitro effects of Escherichia coli lipopolysaccharide on viability and function of human alveolar macrophages. Alveolar macrophages were obtained by fiberoptic bronchoscopy and saline bronchial lavage from 12 normal, nonsmoking volunteers. Cells were
Endotoxin and allergen exposure have been explored in the context of asthma for more than a century. Building upon a pyramid of knowledge are recent observations that provide new insights to the effect of these exposures on the development of asthma. Some of these studies challenge some previously
BACKGROUND
One of the last century's greatest personalities in Occupational Medicine was Enrico Carlo Vigliani (1907-1992), director of the "Clinica del Lavoro" in Milan (1942-1977), editor-in-chief of "La Medicina del Lavoro" (1942-1991), Secretary-Treasurer and then President of the "Permanent
Only those pneumoconioses induced by organic dusts are discussed which are met with in Germany. They comprise: byssinosis which is caused by toxic agents in cotton and flax, farmer's lung, sprayer's fever, exogenous allergic alveolitis due to thermophil actinomyces in the dust of mouldy agricultural
Cotton dust has been found to cause acute pulmonary inflammation and fever in humans and in a guinea pig model of byssinosis. Following 3 h inhalation of cotton dust particles, guinea pig macrophages were found to release ex vivo a factor(s) toxic to WEHI fibrosarcoma cells. The cytotoxic factor(s)
The ubiquitous Gram-negative bacterium Pantoea agglomerans (synonyms: Enterobacter agglomerans, Erwinia herbicola) is known both as an epiphytic microbe developing on the surface of plants and as an endophytic organism living inside the plants. The bacterium occurs also abundantly in plant and
