This study investigates whether there is a significant difference in(More)
BACKGROUND Achieving and maintaining haemostasis is of paramount importance in neurosurgery. Chitosan has been shown in both animal and human models to be significantly effective in haemostasis as well as in reducing adhesion formation. OBJECTIVES To evaluate the haemostatic potential and to study histopathological changes caused by novel chitosan dextran(More)
Background:Staphylococcus aureus (S. aureus) small colony variants (SCVs) can survive within the host intracellular milieu and are associated with chronic relapsing infections. However, it is unknown whether host invasion rates and immune responses differ between SCVs and their wild-type counterparts. This study used a stable S. aureus SCV (WCH-SK2SCV)(More)

INTRODUCTION Post-operative peridural adhesions increase morbidity after neurosurgical procedures. Aim of this study is to assess safety and efficacy of Chitosan-Dextran (CD) gel as an anti-adhesion agent in a spinal laminectomy sheep model. METHODS Eighteen sheep were used in this study with 6 animals in each treatment arm (namely, CD gel, Gelfoam paste(More)
We report the case of a 41 years old woman who presented with massive bleeding after redo mitral valve replacement. A Left ventricular rupture, different from the three known types of wall rupture was hardly identified and controlled with extreme difficulty.
