RESUMEN
We report a case of recurrent laryngeal nerve palsy caused by coalworkers' pneumoconiosis with progressive massive fibrosis (PMF). This illustrates that PMF alone may be added to the list of lesions which can cause recurrent laryngeal nerve palsy. However, efforts should always be made to exclude more common causes, in particular bronchogenic carcinoma, before attributing the palsy to PMF.

The presence of R-plasmid RP1 increased the adhesion of chemostat-grown iron- and carbon-limited Proteus mirabilis to the surfaces of various medical prostheses and to glass. Similar results were obtained with iron-limited Pseudomonas aeruginosa and anaerobically-grown Escherichia coli. Changes in the surface properties of P. mirabilis indicated that the R-plasmid-mediated increase in negative charge was one of the factors that promoted adhesion.
