Burrill Bernard Crohn published paper was "Regional Ileitis: A Pathologic and Clinical Entity". Crohn's work helped correct the thinking that the ailment was actually a form of tuberculosis rather than an inflammatory disease of the gastrointestinal tract. Crohn's work built on the work of Dr. Kennedy Dalziel of Glasgow into regional enteritis twenty years earlier. Crohn always preferred the medically descriptive terms "regional ileitis" and "regional enteritis" to "Crohn's disease", but he was not able to prevent the appropriation of his name for the disease. Some of Crohn's initial research into the causes of the Crohn's disease was centered around his personal conviction
Adult polyglucosan body disease shortage (deficiency) of the glycogen branching enzyme, which leads to the production of abnormal glycogen molecules. These abnormal glycogen molecules, called polyglucosan bodies, accumulate within cells and cause damage. Neurons appear to be particularly vulnerable to the accumulation of polyglucosan bodies in people with this disorder, leading to impaired neuronal function. Some mutations in the "GBE1" gene that cause adult polyglucosan body disease do not result in a shortage of glycogen branching enzyme. In people with these mutations, the activity of this enzyme is normal. How mutations cause the disease in these individuals is unclear. Other people with adult polyglucosan
