When Sutures Fail: Extrusion of an Inspire Device and a Hip Prosthesis in the Same Patient.

Implant extrusion is a rare but serious complication typically linked to infection, poor wound healing, or material intolerance. This case report describes a 79-year-old female patient who experienced extrusion of both a hip prosthesis and an Inspire hypoglossal nerve stimulator (Inspire Medical Systems, Inc., Minnesota, USA), each event associated with the use of Ethibond (Ethicon, Johnson & Johnson, Georgia, USA) sutures.

Dissociating the Influence of Perceptual Biases and Contextual Artifacts Within Target Configurations During the Planning and Control of Visually Guided Action.

The failure of perceptual illusions to elicit corresponding biases within movement supports the view of two visual pathways separately contributing to perception and action. However, several alternative findings may contest this overarching framework. The present study aimed to examine the influence of perceptual illusions within the planning and control of aiming.

Three-dimensional printing of models for preoperative planning and simulation of transcatheter valve replacement.

In this study, we show the use of three-dimensional printing models for preoperative planning of transcatheter valve replacement in a patient with an extreme porcelain aorta. A 70-year-old man with severe aortic stenosis and a porcelain aorta was referred to our center for transcatheter aortic valve replacement. Unfortunately, the patient died after the procedure because of a potential ischemic event.

Clinical use of a simultaneous HPLC assay for indinavir, saquinavir, ritonavir and nelfinavir in children and adults.

PROTEASE INHIBITOR TDM: This study examines the importance of therapeutic drug monitoring (TDM) of protease inhibitors (PI) in adults and children infected with the human immunodeficiency virus (HIV). Pediatric patients were included because information in this population is limited. A high performance liquid chromatographic (HPLC) assay measured indinavir, saquinavir, ritonavir and nelfinavir simultaneously in 0.

Clinical use of a simultaneous HPLC assay for indinavir, saquinavir, ritonavir, and nelfinavir in children and adults.

Protease inhibitor (PI) monitoring may improve the care of human immunodeficiency virus (HIV)-infected patients; however, pediatric data are limited. A high-performance liquid chromatographic (HPLC) assay developed for the simultaneous determination of indinavir, ritonavir, saquinavir, and nelfinavir in 0.2 mL of plasma was used to quantify PI concentrations in HIV patients.

Structural elucidation of metabolites of ritonavir and indinavir by liquid chromatography-mass spectrometry.

The structural elucidation of metabolites of ritonavir and indinavir, HIV-protease inhibitor drugs, by liquid chromatography-electrospray ionization mass spectrometry is described. Ritonavir and indinavir were biotransformed separately by incubation with transplant quality human liver microsomes. The incubation mixture was then analyzed by HPLC coupled to ion trap (ITMS) and triple quadrupole mass analyzers.

Gallium nitrate: effects on cartilage during limb regeneration in the axolotl, Ambystoma mexicanum.

Gallium nitrate, a drug shown to have efficacy in Paget's disease of bone, hypercalcemia of malignancy, and a variety of experimental autoimmune diseases, also inhibits the growth of some types of cancer. We examined dose and timing of administration of gallium nitrate on limb regeneration in the Mexican axolotl, Ambystoma mexicanum. Administered by intraperitoneal injection, gallium nitrate inhibited limb regeneration in a dose-dependent manner.
