Early prenatal detection of an intra-abdominal cryptorchid testicular teratoma.

Intra-abdominal prenatally detected testicular neoplasms are rare; however, increased use of prenatal ultrasonography has led to the discovery of these uncommon neoplasms. We report the fifth case of a prenatally detected intra-abdominal testicular teratoma, which, in this instance, was detected early in pregnancy as a cystic mass within the fetal abdomen that subsequently underwent torsion later in pregnancy before delivery.

Coronary artery calcifications in the long-term follow-up of Kawasaki disease.

Background: To determine if detection of coronary artery calcifications in patients with Kawasaki disease may serve as a noninvasive predictor of future coronary artery events.

Methods: A prospective, cohort pilot study that included 18 patients with Kawasaki disease > 1 year from the acute disease was performed including 9 patients with coronary abnormalities during the acute illness (Group 1) and 9 without coronary abnormalities (Group 2). Patients were classified by echocardiography as having none, resolved, or residual coronary artery abnormalities.

The pylon concept of pelvic anchorage for spinal instrumentation in the human cadaver.

Study Design: Human cadavera morphometric analysis of the iliac columns and biomechanical implant testing of traditional Galveston technique compared to intrailiac instrumentation of the entire iliac column.

Objectives: To describe the anatomy of the iliac columns and to evaluate the strength in forward flexion of a large implant spanning the entire column length compared to standard Galveston technique.

Summary Of Background Data: We have observed substantial and straight columns of bone in the pelvis, connecting the acetabula to the sacrum, which may allow for improved spinopelvic instrumentation.
