A spike-based model of binaural sound localization.

This paper describes a spike-based model of binaural sound localization using interaural time differences (ITDs). To handle the problem of temporal coding and to facilitate a hardware implementation all neurons are simulated by a spike response model, which includes postsynaptic potentials (PSPs) and a refractory period. A winner-take-all (WTA) network selects the dominant source from the representation of the sound's angles of incidences, and can be biased by a multisensory support. We use simulations on real audio data to investigate the function and the practical application of the system.

Special report: protection and advocacy: what nurses need to know.

There is a national system of protection and advocacy programs for people with mental illness, developmental disabilities, and other disabilities. These programs investigate allegations of abuse and neglect and pursue legal, administrative, and other appropriate remedies to protect the rights of individuals with disabilities. Nurses have a critical role in advocating and protecting rights of consumers with psychiatric disabilities and identifying and reporting incidents of abuse and neglect. The unique role of the nurse within practice, research and education regarding protection and advocacy is discussed.

Laparoscopic removal of a large laparotomy pad forgotten in situ.

Objects forgotten during surgery are still an important complication with ethical and forensic implications. This case report describes a splenectomized patient with type II Hodgkin's disease. A large laparotomy pad (68 x 48 cm) forgotten in situ during a staging operation 6 months previously was removed laparoscopically. In asplenic patients with a permanent immune deficiency it is especially advantageous to perform surgery via the "closed" route whenever possible.

Laparoscopic partial splenic resection.

Twenty domestic pigs with an average weight of 30 kg were subjected to laparoscopic partial splenic resection with the aim of determining the feasibility, reliability, and safety of this procedure. Unlike the human spleen, the pig spleen is perpendicular to the body's long axis, and it is long and slender. The parenchyma was severed through the middle third, where the organ is thickest. An 18-mm trocar with a 60-mm Endopath linear cutter was used for the resection. The tissue was removed with a 33-mm trocar. The operation was successfully concluded in all animals. No capsule tears occurred as a result of applying the stapler. Optimal hemostasis was achieved on the resected edges in all animals. Although these findings cannot be extended to human surgery without reservations, we suggest that diagnostic partial resection and minor cyst resections are ideal initial indications for this minimally invasive approach.
