Esdaile J M - - 1987
The 1960s epidemic of asthma deaths that affected young persons in England and Wales, as well as in other countries, was attributed to the effect of newly available pressurized aerosols containing sympathomimetic bronchodilators. The subsequent decision to ban the nonprescription sale of these agents in the United Kingdom represented a ...

Allergic bronchopulmonary aspergillosis (ABPA), a serious complication of asthma, is thought to rarely afflict infants. We report three children less than 2 years of age in whom this disorder developed. The major criteria for the diagnosis include: (1) asthma, (2) recurrent pulmonary infiltrations with peripheral eosinophilia, (3) positive aspergillus skin ...
Chambers T J - - 1977
Following the demonstration by Chambers (1977a,b and c) that simultaneous attachment of macrophages to endocytogenic material in vitro leads to fusion, as analysis of the phagocytic potential of giant cells has provided evidence that the same mechanism is operating in macrophage polykaryon formation in vovo. Unlike previously proposed models for ...
Ng R - - 1977
Lead poisoning occurred in two infants, causing lead encephalopathy in one but no symptoms in the other. Both infants had been fed a formula prepared with water boiled in a lead-soldered electric kettle. The diagnosis was suggested by dense metaphyseal bands in radiographs, illustrating the importance of careful examination of ...
