Building a diabetes registry from the Veterans Health Administration's computerized patient record system.

Background: Little information is available describing how to implement a disease registry from an electronic patient record system. The aim of this report is to describe the technology, methods, and utility of a diabetes registry populated by the Veterans Health Information Systems Architecture (VistA), which underlies the computerized patient record system of the Veterans Health Administration (VHA) in Veteran Affairs Integrated Service Network 10 (VISN 10).

Methods: VISN 10 data from VistA were mapped to a relational SQL-based data system using KB_SQL software.

Persistent patent urachus with allantoic cyst: a case report.

Patent urachus results when there is a persistence of an allantois remnant which normally undergoes atresia during embryological development. It can lead to an abdominal wall defect similar in appearance on ultrasound to an omphalocele. A 34-year-old primigravida presented at 19 weeks' gestation for evaluation of a cystic mass arising at the umbilical cord insertion.

A constitutive relationship for large deformation finite element modeling of brain tissue.

Finite element modeling of the finite deformation response of soft tissues presents a formidable challenge. This paper discusses the use of a large strain constitutive relationship suitable for modeling brain tissue as well as other soft biological tissue. Available experimental data on the finite deformation response of brain tissue is used to characterize the constitutive properties.

Impact trauma of the human temporal bone.

A cooperative study between the Department of Otorhinolaryngology and the Highway Safety Research institute of the University of Michigan was designed to study temporal bone fracture produced in cadavers subjected to realistic automotive impact situations. Utilizing sled and piston impact configurations frontal and parietal impacts were noted to produce ipsilateral and contralateral fractures of nine temporal bones in seven cadavers. The impact velocities varied between 18.
