[Intratracheal foreign body caused by a sheared endotracheal intubation stylet]. / Intratrachealer Fremdkörper durch eine abgescherte Einführhilfe.

After orotracheal intubation of a 30-year-old man with a flexible tube, a floating foreign body was noticed inside the tube. The subsequent bronchoscopy revealed a second foreign body near the bifurcation of the trachea. Both foreign bodies were removed successfully and identified as parts of the plastic-sheathed stylet. Fatigue of material is discussed as the reason for the broken reusable stylet during intubation.

Specific inhibition of hepatitis C viral gene expression by non-polar (phenylalkyl)phosphonates.

Different phenylalkyl backbone modified antisense oligonucleotides complementary to the Hepatitis C virus (HCV) RNA nucleotides 326-342 were synthesized. The lipohilic character of modified oligonucleotides was determined from RP-HPLC retention times. The inhibitory effect of these antisense oligonucleotides on HCV gene expression was analyzed in an in vitro test system.
