Malfunctioning sufentanil intrathecal pain pump: a case report.

Background: Sufentanil is a potent opioid uncommonly used to manage pain and is rarely administered via an intrathecal pain pump system.

Case Presentation: This case illustrates the use of intrathecal sufentanil in a 50-year-old Caucasian man for the management of chronic pain; however, the intrathecal drug delivery system experienced a malfunction which led to 1/100th output of the correct dosage. Interesting aspects of this case report include the uncommon choice of sufentanil use for an intrathecal drug delivery system, as well as the unusual pharmacokinetics of this drug.

Tissue-Specific DNA Replication Defects in Caused by a Meier-Gorlin Syndrome Mutation in Orc4.

Meier-Gorlin syndrome is a rare recessive disorder characterized by a number of distinct tissue-specific developmental defects. Genes encoding members of the origin recognition complex (ORC) and additional proteins essential for DNA replication (CDC6, CDT1, GMNN, CDC45, MCM5, and DONSON) are mutated in individuals diagnosed with MGS. The essential role of ORC is to license origins during the G1 phase of the cell cycle, but ORC has also been implicated in several nonreplicative functions.
