In the wake of the bacterial revolution after Robert Koch identified the tuberculosis bacillus, medical and public health professionals classified the various forms of consumption and phthisis as a single disease--tuberculosis. In large measure, historians have adopted that perspective. While there is undoubtedly a great deal of truth in this conceptualization, we argue that it obscures almost as much as it illuminates. By collapsing the nineteenth-century terms phthisis and consumption into tuberculosis, we maintain that historians have not understood the effect of non-bacterial consumption on working-class populations who suffered from the symptoms of coughing, wasting away, and losing weight. In this essay, we explore how, in the nineteenth century, what we now recognize as silicosis was referred to as miners' "con," stonecutters' phthisis, and other industry-specific forms of phthisis and consumption. We examine how the later and narrower view of the bacterial origins of tuberculosis limited the medical professions' ability to diagnose and understand diseases caused by industrial dust. This paper explores the contention that developed at the turn of the century over occupational lung disease and tuberculosis and the circumstances that led to the unmasking of silicosis as a disease category.

Lung cancer often develops in individuals with pre-existing pulmonary and cardiac pathology. Many of these individuals with pre-existing pathology are also at risk of occupational lung disease. New and worsening symptoms can be secondary to pre-existing pathology, progressive cancer or treatment. Pulmonary toxicity, including interstitial lung disease, following radiotherapy and conventional cytotoxic chemotherapy (e.g. cyclophosphamide, bleomycin), has been recognised for many years. Pulmonary toxicity also occurs with the newer classes of cytotoxic agents, including the deoxycytidine analogue gemcitabine. A small percentage (0.88%) of patients treated with the epidermal growth factor receptor tyrosine kinase inhibitor gefitinib have developed interstitial lung disease. This complication has been reported at a higher frequency in Japanese patients than in US patients (1.9% vs 0.34%, respectively) and in those with pre-existing pulmonary fibrosis. This review discusses the difficulties in both recognition and treatment of gefitinib-associated interstitial lung disease. Symptoms are vague, such as dyspnoea, cough and fever and can be difficult to differentiate from progressive disease, co-existing morbidity and new pulmonary pathology. Diagnosis is, therefore, by rigorous investigation to exclude all other differential diagnoses. Treatment, at present, is supportive and includes discontinuation of gefitinib, oxygen supplementation, high-dose corticosteroids and antibacterials.

This paper summarizes "Respiratory Issues in Confined Feeding Operations," a panel discussion at the Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," Dallas/Fort Worth, Texas, January 27-28, 2010. Occupational exposure to confined animal feeding operations is associated with cough, wheezing, and shortness of breath. Published data shows that 20% to 40% of hog confinement workers experience such symptoms, although most are able to continue working in this industry. Endotoxin is one component of hog barn dust that is associated with respiratory disease in workers. Endotoxin levels on cattle feedlots can also be in the range linked with occupational lung disease. The cattle industry has not yet prepared guidance documents for producers, in part because much less is known about the prevalence of lung disease in its workers. However, the pork industry provides information for pork producers on reducing their respiratory health risks through a multifaceted approach, including the use of respirators. Some jobs cannot be done safely without respiratory protection, such as entering manure pits. It is less clear for other jobs when respirators should be worn. Use of respiratory protection should be considered but not mandated for all persons working in close proximity to livestock in dusty conditions. A respiratory protection program may also serve as a cost effective biosecurity measure to protect animals from human pathogens such as influenza virus. Proper design and management of barn ventilation systems is critical for maintaining temperature and humidity levels for optimal animal growth; as well as decreasing the level of gases and respirable dusts. The pork and the cattle industries support occupational health and safety; however, the governmental guidance and recommendations for such programs are limited for the agricultural industries as a whole. The industries should lead the way in the effort to improve respiratory protection for workers. Overall, a team approach that includes input from managers, workers, and veterinarians is important for the reduction of respiratory hazards on livestock farms.

Sandblasting is one of the occupational causes of silicosis. This report details three cases diagnosed as silicosis caused by sandblasting in Teflon-coated pan manufacturing: Case 1--A 24-year-old man admitted with dyspnea and cough; Case 2--An 18-year-old man admitted with shortness of breath and fever; and Case 3--A 25-year-old man admitted with dyspnea and weight loss. Chest examinations of the first and second cases revealed crackles in both lungs, but the third case was normal, no crackles. Chest x-rays showed bilateral reticulonodular densities and hilar enlargement in all cases. They were clinically and radiologically diagnosed as silicosis due to occupational exposure. All cases had worked in the sandblasting unit at a Teflon-coated pan manufacturing factory for one to three years. Silicosis is a preventable occupational lung disease, but no effective treatment is available for the disease yet. Improving workplace conditions is the most effective way to prevent silicosis.
