From 1770 to 1772 Jenner received advanced training in London at St Georges Hospital and as the private pupil of John Hunter, then returned to set up practice in Berkeley.Perhaps there was already an informal public understanding of some connection between disease resistance and working with cattle. The "beautiful milkmaid" seems to have been a frequent image in the art and literature of this period. But it is known for certain that in the years following 1770, at least six people in England and Germany (Sevel, Jensen, Jesty 1774, Rendall, Plett 1791) tested successfully the possibility of using the cowpox vaccine as an immunization for smallpox in humans. Jenner sent a paper reporting his observations to the Royal Society in April 1797. It was not submitted formally and there is no mention of it in the Societys records. Jenner had sent the paper informally to Sir Joseph Banks, the Societys president, who asked Everard Home for his views. Reviews of his rejected report, published for the first time in 1999, were skeptical and called for further vaccinations. Additional vaccinations were performed and in 1798 Jenner published his work entitled An Inquiry into the Causes and Effects of the Variolae Vaccinae, a disease discovered in some of the western counties of England, particularly Gloucestershire and Known by the Name of Cow Pox. It was an analysis of 23 cases including several individuals who had resisted natural exposure after previous cowpox. It is not known how many Jenner vaccinated or challenged by inoculation with smallpox virus; e.g.
This method of treatment can be problematic in that the Ilizarov might need to be applied both during early childhood (to keep the femur from being extremely short at the onset of growth) and after puberty (to match leg lengths after growth has ended). The clear benefit of this approach, however, is that no prosthetics are needed and at the conclusion of surgical procedures the patient will not be biologically or anatomically different from a person born without PFFD.In some cases the patient may not request treatment and instead elect to use a wheelchair or other aids to assist mobility.
