Marijuana Use and Complication Risk Following Tibia Shaft Fracture Fixation.

Objectives: The aim of this study was to investigate the relationship between preoperative marijuana use and complications following tibia shaft fracture fixation.

Methods: Design: Retrospective cohort study.

Setting: Two academic Level I trauma centers.

Iatrogenic Sciatic Nerve Injury in Posterior Acetabular Surgery: Surgeon More Predictive Than Position.

Objectives: To identify factors that contribute to iatrogenic sciatic nerve palsy during acetabular surgery through a Kocher-Langenbeck approach and to evaluate if variation among individual surgeons exists.

Design: Retrospective cohort.

Setting: Level I trauma center.

Management of Femoral and Tibial Shaft Fractures in Patients With Chronic Spinal Cord Injury.

Objectives: To compare outcomes and complications between nonoperative and operative management of femur and tibia fractures in patients with paraplegia or quadriplegia from chronic spinal cord injury (SCI).

Design: Retrospective cohort study.

Setting: Three Level-1 Trauma centers.

Emotions and music through an innovative project during compulsory secondary education.

This article presents the results and main conclusions of a quasi-experimental study after the implementation of an innovative project extended as a multi-year programme, called 'MusMotion', applied in compulsory secondary education, which is based on the relationship between music and emotions, as well as its effects on the academic performance of adolescents. The research analysed and tested an educational innovation project that improves students' academic performance, as well as the classroom climate between teachers and students ( = 444). A key strand of this research concerns the use of music to support students' emotional development and awareness.

Single-Incision, Four-Compartment Fasciotomy and Application of Negative Pressure Dressing for Compartment Syndrome of the Leg.

The video described by this article presents a safe and effective technique for single-incision, 4-compartment fasciotomy of the leg in a patient with a tibial plateau fracture and clinically diagnosed compartment syndrome. We also demonstrate a technique for the application of a negative pressure wound dressing when delayed closure or coverage is planned.

Dorsal Impaction Injuries of the Distal Radius: Operative Technique Through Dorsal Approach to the Wrist.

Distal radius fractures vary widely in fracture pattern and displacement. Impaction injuries involving the dorsal articular surface of the distal radius can present challenges when anatomic reduction and fixation is attempted through a standard volar approach. Dorsal approach to the distal radius can provide direct visualization of these fracture patterns, greatly facilitating anatomic reduction and stabilization.

Distributed, layered and reliable computing nets to represent neuronal receptive fields.

Receptive fields of retinal and other sensory neurons show a large variety of spatiotemporal linear and non linear types of responses to local stimuli. In visual neurons, these responses present either asymmetric sensitive zones or center-surround organization. In most cases, the nature of the responses suggests the existence of a kind of distributed computation prior to the integration by the final cell which is evidently supported by the anatomy.

Remarks on neurocybernetics and its links to computing science. To the memory of Prof. Luigi M. Ricciardi.

This paper explores the origins and content of neurocybernetics and its links to artificial intelligence, computer science and knowledge engineering. Starting with three remarkable pieces of work, we center attention on a number of events that initiated and developed basic topics that are still nowadays a matter of research and inquire, from goal directed activity theories to circular causality and to reverberations and learning. Within this context, we pay tribute to the memory of Prof.

On the legacy of W.S. McCulloch.

In this paper, we review McCulloch's legacy, from his early work in neurophysiology, and its relationship to his philosophical quest for an 'experimental epistemology' to his role in the cybernetics movement during the 1940s and 1950s and his contributions to the development of computer science and communication theory. There are three parts in chronological sequence. First, the period up to his work at Yale University with Dusser de Barenne, where he concentrated on the experimental study of the functional organization of sensory cortex.
