Excerpt: . . . are neither large nor numerous (as in phosgene cases). In such patches there is crepitation, but practically everywhere else the lung is doughy and airless (Fig. 1). On section, clear fluid and blood pour out like water from a squeezed sponge. The tissue is red and semi-translucent with occasional lighter, air-containing patches. Near the margins of the upper lobes, there are a few small emphysematous areas. The bronchi, like the lung proper, are full of fluid, and in the large branches, there is some froth. The mucosa is somewhat reddened, and that of the smallest branches is rather opaque. About each there is a zone of edema, which is also conspicuous about the larger blood vessels. The trachea is full of sticky froth. Its mucosa is slightly reddened but is otherwise normal. The remaining organs, --liver, spleen, kidneys, adrenals, gastrointestinal tract, brain, --are negative. Microscopic Findings: There is little worthy of note aside from the respiratory tract. The tracheal epithelium is practically everywhere intact, but in places the superficial cells are somewhat shrunken and distorted and have lost their cilia; a few are desquamated. In the largest bronchi a similar condition is seen, but as one passes downward into the mediumsized cartilage-containing tubes, the injury is far more serious. The superficial cells are quite necrotic, and the entire layer is partially loosened from the wall (Fig. 5). In the bronchioles and atria, there is not only death of the living cells but necrosis of the wall itself (Fig. 6). The lung tissue shows practically everywhere a complete filling of the alveoli with coagulated edematous fluid, which is quite rich in albumin (Figs. 3 and 5). A few air bubbles are seen, but these are more prominent in the. . . This item ships from La Vergne,TN., RareBooksClub, RareBooksClub. Paperback. New. This item is printed on demand.

Extrait: . . . des plus difficiles soigner. Les auteurs se sont efforcs dtablir des formes cliniques daprs le groupement des divers lments morbides, daprs la rapidit de la marche, afin de prciser les indications thrapeutiques les plus convenables dans chacune de ces formes, forme suraigu ou catarrhe suffocant, forme aigu, forme subaigu cachectique. On pourrait dire quil y a lieu surtout denvisager au point de vue du traitement les cas dans lesquels prdominent les dangers dasphyxie formes asphyxiques, congestives), ceux o le danger vient surtout de lasystolie (formes cardioplgiques), ceux o les phnomnes gnraux dordre nerveux (dlire, convulsions) sont surtout sous la dpendance de llvation excessive de la temprature (formes hyperthermiques ou nerveuses), ceux enfin o le danger rside dans linsuffisance de la nutrition (formes asthniques, cachectisantes ou athrepsiantes). Mais il ne faut pas perdre de vue que ces distinctions et classifications sont des schmas arbitraires, et que dans la ralit on peut rencontrer au cours dune broncho-pneumonie ces diverses tendances successivement. Le danger dasphyxie est au maximum dans les formes o une bronchitediiuse des bronches moyennes, succde rapidement linflammation des bronchioles sus-lobulaires et des lobules avec un raptus congestif qui a pour consquence daplatir par lafflux du sang les alvoles dj encombrs par la desquamation pithliale, lexsudatfibrineux et ladiapdse leucocytique;. . .

The injected condition of the tracheal mucosa during asthma I have already mentioned, and this is bound to extend lower down into the bronchi. It is fair criticism to say that this may be the result, not the cause, of the dyspnoea and coughing; but as we have seen in preceding chapters, even in typical asthma, there are vascular phenomena (urticaria, erythema, petechiae, Raynauds symptoms) and the symptoms are more like catarrh, and less like spasm in atypical asthma--the apyretic recurrent bronchitis of children, which is admittedly asthma, the paroxysmal pulmonary oedema of the adult which may alternate with it. Laryngismus stridulus, we have seen, shades into laryngitis stridulosa, and in the next chapter we shall see that paroxysmal sneezing and rhinitis are largely due to the same toxaemic conditions that produce asthma. So struck was Gee by the catarrh which manifestly attends most, if not all, asthmatic seizures that he relegated spasm to quite a subordinate position and adopted the hypothesis of pneumonic asthma. Asthmatic attacks often end with profuse expectoration. If toxaemia result in spasm of the bronchial tubes, why should it not also result in spasm of the bronchial arteries which, coming from the systemic circulation, ramify to the uttermost bronchioles and are under vasomotor control Why should there not result here the same peculiar vascular condition as in the urticaria, which so often besets the skin of asthmatics We may still ask the same question if we adopt recent views as to urticaria being a direct action of toxin on vessel wall.

The new agency adopted the old voluntary limit, but recognized a 3 change was necessary. In 1975, NIOSH urged a limit of 1 ug m, basing this rec-ommendation on dozens of studies, which were remarkable at the time for their focus on this single carcinogen. Today, OSHA estimates that more than 500, 000 20 U. S. workers are exposed to CrVI. It took 30 years and a court order for OSHA to issue a new standard, albeit one allowing exposure five times higher than NIOSH recommended in 1975. 21 Diacetyl Diacetyl is a commonly used food flavoring and is the primary constituent of arti-ficial butter flavoring. There is compelling scientific evidence linking occupational exposure to diacetyl to bronchiolitis obliterans, a rare, debilitating and sometimes fatal lung disease. On April 26, 2002, exactly 5 years before the date of this hearing, NIOSH published a widely disseminated report about the risk of bronchiolitis obliterans in microwave popcorn factories. Dozens of workers at factories where these flavors are produced, mixed or applied have become sick, and at least three workers have died. Others are awaiting lung transplants. While the index cases were seen at microwave popcorn factories, scientists now recognize a health risk to thousands of other food industry employees using diacetyl in manufacturing both ar-tificial flavorings and associated products including candy, pastries, and frozen foods. The California Department of Health Services, for example, recently reported 20 new cases of respiratory impairment at factories where flavorings are produced; one of the first cases reported in California was in a worker exposed mixing flavors for dog food.
