Accuracy of computed tomography in the detection of blunt bowel and mesenteric injuries.

Background: There are conflicting views on the accuracy of computed tomography (CT) findings in patients with bowel and mesenteric injuries (BMIs) following blunt abdominal trauma. The aim of the present study was to assess the accuracy of the CT report during a trauma call.

Methods: Ninety-eight patients underwent preoperative abdominal spiral CT and subsequent laparotomy following blunt trauma between January 1996 and March 2001 at a level I trauma centre.

Cervical chordoma: case report.

Chordomas of the cervical spine are rare. A case of a cervical chordoma is described. The initial radiological misinterpretation was due to the unavailability of CT myelography or MRI.

Transient global amnesia following cerebral angiography with non-ionic contrast medium.

Transient global amnesia (TGA) is an uncommon syndrome of recent memory deficit and inability to learn new data, usually resolving within 24 h. Two cases following use of non-ionic contrast media in cerebral angiography are described. The neuroanatomy of memory is reviewed.

Clival chordomas.

Three cases of clival chordomas are reviewed and the findings are compared to those in the recent literature. In the first case the tumour arose from the basion, spreading downwards to invade the upper cervical canal and the paravertebral fascial planes. The second case is a rare case since it affects a 12 year old pre-adolescent boy.

Fluoride intake and utilization by Hungarian children: associations and interrelationships.

Selected interactions were examined between F, Al, Ca and Mg intakes and their manifestations in dental health parameters and biological samples relating to Hungarian children. The prevalence (DMFT, DMFS) and severity (SR) of caries were inversely related to the F concentration of household water and to the amount of F ingested from foods, beverages and tap or well water. Dental fluorosis and the F content of enamel, plaque, saliva, urine, nails and hair were directly related to the F content of water and to dietary F intake.
