Dopaminomimetic psychosis in Parkinson's disease: first symptom of early dementia?
More studies are needed to asses the relationship between parkinsonian psychosis and early dementia. Additional, the development of new drugs could be helpful to control these psychotic symptoms in PD without serious secondary effects.
Pancreatic well-differentiated neuroendocrine tumors frequently express PAX8, which can help distinguish pancreatic primary tumors from tumors of other anatomic sites. In contrast, PAX8 expression in poorly differentiated neuroendocrine carcinomas is not specific for pancreatic origin and can be seen in extrapancreatic poorly differentiated neuroendocrine carcinomas.
