    ABSTRACT: We report the case of a 79-year-old woman who developed a rapidly progressive dementia (RPD) with severe memory impairment, early visual hallucinations and extrapyramidal signs. Symptoms started suddenly after hip replacement surgery following an accidental fall. Motor epileptic seizures appeared at the end of the illness. Dementia worsened gradually leading to akinetic mutism. She died five and a half months after the onset of symptoms. MRI showed cerebral atrophy but failed to detect any other lesion. Results of all laboratory tests performed were negative. After the most frequent treatable diseases were excluded, the diagnosis of dementia with Lewy bodies was initially considered. CJD was also suggested based on the rapid evolution of the disease and the positivity of 14-3-3 protein in CSF. Neuropathological examination revealed an extensive miliary metastatic dissemination from an unknown primary adenocarcinoma. Pulmonary origin was suggested according to the immunohistochemical profile. Histopathological changes of Alzheimer's disease were also observed in the cerebral cortex and hippocampus. Neither Lewy bodies nor PrP deposits were found. The sudden onset of the dementia just after the hip replacement surgery raises the possibility of a pathological fracture with secondary tumoral microembolic dissemination. Despite its rarity, this entity should be included in the differential diagnosis of RPD. This case illustrates the definite importance of neuropathological post-mortem examination in order to elucidate the different types of dementia.

    ABSTRACT: The Meixoeiro Hospital Brain Bank (BB) was established at the end of 2002. A BB is a tissue collection and storage system, established under the best conditions to carry out prospective morphological, biochemical or molecular studies. The BB should ideally be supported by a donor program, although samples may also be obtained from autopsy material from patients with neurodegenerative diseases. Recruitment of control cases from brains without neurological diseases is basic. The main goal of a BB is to provide brain tissue for research. Each case requires accurate clinical data, a definite diagnosis and optimal conditions of tissue preservation. The use of protocols to standardize the handling and processing of tissues, data recruitment and neuropathological diagnosis is fundamental to assure the quality and homogeneity of samples. Close collaboration between neuropathologists, neurologists and other specialists is essential in all the process. Although important advances in the tissue banking field have been achieved, the number of donors in Spain still remains low. Stronger institutional support as well as public awareness through better diffusion of the information is necessary to increase the number of donors and improve BB development.
