The question of whether thread- and tangle-like inclusions of the choroid plexus (known as Biondi inclusions) are related to the cortical lesions in Alzheimer disease (AD) has been debated for almost a century, yet remains unanswered. Recently beta-amyloid protein was biochemically isolated from the plexus, indicating a possible pathogenetic relationship(More)
Breast cancer is the most frequent cancer among women. Screening programs are able to diagnose early lesions in an infra-clinic state. Percutaneous procedures are simple to do and well tolerated by women, they provide an histological diagnosis. This way of doing may reensure rapidly, without a surgical approach, the women with benign lesions. In cases of(More)
Dynamic computed tomography (CT) is frequently performed to assess the mediastinum in trauma patients with a suspected thoracic aortic rupture. Its usefulness lies in demonstrating a mediastinal hematoma. However, many patients still undergo conventional aortography despite a normal chest. CT, because of a perceived insensitivity of this technique for(More)
The filamentous brain lesions that define Alzheimer disease (AD) consist of senile plaques and neurofibrillary tangles. Undulated pathological filaments--curly fibers or neuropil threads--also occur in the neuropil. Beta-amyloid precursor proteins are synthesized by many cells outside the central nervous system and recently, deposition of(More)
Fuel oil distribution companies service their customers with fleets of tanker lorries. The problem is to find a set of routes minimising the number of travelled kilometres and the number of used vehicles, while satisfying customer demand. There are three major problems why traditional Operations Research techniques are not enough to deal with this problem,(More)
Current value of sonography for the characterization of focal liver lesions Incidental focal lesions are frequently discovered during sonographic exploration of the liver. Solid lesions remain often questionable, particularly in oncological or infectious patients. Doppler exploration generally doesn't help and other modalities, such as CT, MRI or even(More)
UNLABELLED Undifferentiated sarcoma of the liver is a rare primary tumor of childhood: only about 150 cases have been reported in the literature. CASE-REPORT A 10 year-old girl was admitted because of diarrhea and weight loss. Sonography, then CT-scan and MRI showed a large tumor of the liver. COMMENTS In the differential diagnosis of primary liver(More)
Approximately 1% of the fetuses present some dilatation of their urinary tract in utero. More than 50% of these antenatally detected hydronephrosis will disappear spontaneously after birth. The other 50% comprises ureteropelvic junction obstruction, vesico-ureteral reflux and primary megaureters. Postnatal radiological evaluation (renal ultrasonography and(More)
