Magnetic duodenoileal anastomosis with sleeve gastrectomy: a prospective multicenter study.

Background: Magnetic digestive anastomosis has the potential to reduce anastomotic complications and complexity. We report the 1-year results of a new surgical technique using Self-forming Neodymium magnet Anastomosis Procedure with Sleeve gastrectomy (SNAP-S; GI Windows).

Methods: This was a prospective, nonrandomized multicenter trial.

Superficial palmar arch aneurysm secondary to blunt trauma: Bag of ice versus bare hand!

A 45-year-old male prisoner was referred to the orthopedic outpatients clinic after he sustained a blunt palmar injury when he tried to break-up a bag of ice with the volar aspect of his hand. A few months later a pulsatile expansile mass developed at the site of blunt trauma affecting flexion and extension of the fingers and inability to hold objects. A computed tomography angiogram confirmed the mass to be a true aneurysm of the superficial palmar arch 3 cm in size.

The detection of ACTH and insulin in equine plasma by solid-phase extraction and micro-flow LC/MSMS.

Previous liquid chromatography/mass spectrometry (LC/MS) methods for the detection of insulin and other similar peptide hormones in equine plasma relied on the use of antibody affinity extraction. As a result, these methods were not suitable for routine high-throughput analysis. A solid-phase extraction (SPE) method incorporating size exclusion as well as reversed-phase interactions allows the selective extraction of peptide hormones such as adrenocorticotropic hormone (ACTH), insulin and their synthetic analogues from equine plasma with approximately 80% extraction efficiencies.
