Efficacy of Continuous Intrathecal Infusion Trialing with a Mixture of Fentanyl and Bupivacaine in Chronic Low Back Pain Patients.

Intrathecal trialing is used as a screening prognostic measure prior to intrathecal drug delivery system implant. The purpose of this study was to determine the efficacy of a continuous intrathecal infusion of an admixture of bupivacaine and fentanyl in patients with chronic low back pain. Patients with refractory chronic low back pain in the setting of previous lumbar spine surgery and/or chronic vertebral compression fracture(s) were enrolled in a randomized double blind cross-over study comparing saline infusion to infusion of a solution containing bupivacaine combined with low-dose fentanyl over a 14-18 hour period.

Mitochondrial DNA analysis of the putative skeletal remains of Sieur de Marle: Genetic support for anthropological assessment of biogeographic ancestry.

In 1932, seven burials were discovered on a Texas plantation that was originally the site of a 17th-century Caddo Indian village. Of the seven excavated graves, one set of remains (an adult male) was notably buried in a manner inconsistent with traditional Caddoan burial practices and has long been purported to be the remains of Sieur de Marle (a member of the French explorer La Salle's last expedition). Diary accounts of La Salle's expedition scribe report that Sieur de Marle died along a river near an Indian village during a trek to Canada to find help for colonists left behind at the ill-fated Fort St.

Forensic genetic investigation of human skeletal remains recovered from the La Belle shipwreck.

In 1995, the historical shipwreck of La Belle was discovered off the coast of Texas. One partial human skeleton was recovered from alongside cargo in the rear portion of the ship; a second (complete) skeleton was found atop coiled anchor rope in the bow. In late 2015, comprehensive forensic genetic testing began on multiple samplings from each set of remains.

Factors contributing to patient nonattendance at open-access endoscopy.

Patients who miss endoscopy appointments cause inefficient utilization of medical resources. Because national nonattendance rates are as high as 27% and reasons for nonattendance have not been well studied, we sought to quantitate nonattendance at our tertiary care institution. We conducted a retrospective records review of the institutional database to identify patients who did not attend a scheduled endoscopy appointment between January 2000 and December 2003.

Yield of repeat wireless video capsule endoscopy in patients with obscure gastrointestinal bleeding.

Purpose: Capsule endoscopy (CE) has been shown to have a high diagnostic yield in patients with obscure gastrointestinal bleeding (OGIB). It is not known if repeating CE improves diagnostic yield or changes patient management when the initial CE is negative or nondiagnostic. The aims of this study are (1) to understand the reasons for repeat CE, (2) to determine the diagnostic yield of repeat CE, and (3) to establish if findings on repeat CE resulted in a change in patient management.
