Differentiation Between Pyogenic Flexor Tenosynovitis and Other Finger Infections.

Background: Hospital transfer decisions regarding pyogenic flexor tenosynovitis (PFT) are made difficult by emergency department presentations similar to other finger infections, with pain, redness, and functional limitation. Our objectives were to: (1) determine diagnostic sensitivity and specificity of Kanavel signs; and (2) identify existing factors most predictive of PFT during initial presentation.

Methods: Adult patients who underwent surgical consultation for concern of PFT over a 5-year period were identified retrospectively.

Prosthetic Design in Total Wrist Arthroplasty.

Total wrist arthroplasty (TWA) provides a motion-preserving alternative to total wrist arthrodesis for low-demand patients with debilitating pancarpal arthritis. The earlier generation total wrist implants had high complication and failure rates. Advances in prosthetic design have contributed to improved clinical outcomes and implant survivorship.

Limited intercarpal fusion as a salvage procedure for advanced Kienbock disease.

Background: With progressive lunate collapse, salvage procedures in advanced Kienbock disease attempt to provide pain relief and maintain motion. Scaphocapitate arthrodesis may provide a durable option with comparable outcomes to proximal row carpectomy in the well-selected patient.

Methods: We performed a retrospective chart review of all consecutive patients with Lichtman stage IIIA or IIIB Kienbock's disease who underwent either scaphocapitate or scaphotrapeziotrapezoid-capitate arthrodesis from January 2004 to December 2013.

Management of complications after rotator cuff surgery.

Rotator cuff repair (RCR) is a common procedure performed by orthopedic surgeons via arthroscopic, open, or mini-open techniques. While this surgery is considered to be of low morbidity, several potential complications can arise either intraoperatively or during the postoperative time period. Some of these complications are related to the surgical approach (arthroscopic or open), while others are patient dependent.

Methamphetamine enhances memory of operantly conditioned respiratory behavior in the snail Lymnaea stagnalis.

Amphetamines have been used as cognitive enhancers to promote learning and memory. Amphetamines are also drugs of abuse that may promote the initiation of strong memories that ultimately lead to addiction. To understand how methamphetamine (Meth) may be augmenting learning and memory, we chose a relatively simple system, the pond snail, Lymnaea stagnalis.
