[Neuropathologic investigation in autopsies with special emphasis on findings in Alzheimer's disease].

Out of an average total of 1400 autopsies per year, neuropathological examinations were performed in 477 cases between 1997 and 1999 to investigate the incidence of dementias. The majority of the studied subjects were over 50 years old. Bielschowsky's and/or Gallyas's silver methods and, in some cases, protein tau (MAP) immunocytochemistry and amyloid staining were performed beside routine examination.

Surgical management of peripancreatic arterial aneurysms.

Peripancreatic artery aneurysms--gastroduodenal (GDA) and pancreaticoduodenal (PDA)--are highly unusual. We report 4 such aneurysms and have collated reports of true peripancreatic artery aneurysms based on an extensive review of the English literature. From this review, patient characteristics, clinical behavior, outcome and management strategies are assessed.

Surveillance venous duplex is not clinically useful after total joint arthroplasty when effective deep venous thrombosis prophylaxis is used.

The early detection of deep venous thrombosis (DVT) and treatment with systemic anticoagulation to prevent pulmonary embolism (PE) are essential in the management of patients undergoing total joint arthroplasty (TJA). However, improvements in prophylactic measures have significantly decreased the occurrence of DVT in these patients. The purpose of this study was to determine whether routine postoperative duplex surveillance for DVT remains clinically useful.

Endovascular repair of external iliac artery occlusion after hip prosthesis migration.

Purpose: To report emergent endovascular intervention to restore lower extremity arterial patency after migration of a hip prosthesis caused thrombosis of the external iliac artery (EIA).

Case Report: Nine months following left hip revision arthroplasty, a 66-year-old woman presented to the Emergency Department with the complaints of an acutely painful left lower extremity for over 6 hours. Imaging showed the metallic acetabular portion of the hip prosthesis in the iliac fossa, with severe external compression of the EIA.

Enoxaparin treatment in high-risk trauma patients limits the utility of surveillance venous duplex scanning.

Objective: The value of surveillance venous duplex scanning for detecting unsuspected deep venous thrombosis (DVT) in trauma patients who are receiving enoxaparin prophylaxis is open to question. This study was undertaken to determine whether enoxaparin reduced the clinical utility of surveillance scanning and whether management of these patients was altered by findings of the scans.

Methods: The medical records of trauma patients who met defined criteria for high DVT risk, admitted during 30 consecutive months, were reviewed.
