OBJECTIVES: Cognitive remediation therapy (CRT) has shown significant improvement in cognition in schizophrenia. However, effect sizes of CRT have been reported to be modest raising the issue how to augment the effects of CRT on neurocognition and social cognition. Our aim was to examine whether the addition of computerized social cognition training would enhance the effects on neurocognition and social cognition as compared to CRT alone. METHODS: This is a 12-week, parallel group trial of 131 in- and out-patients with schizophrenia randomized to CRT (COGPACK or Brain Fitness) with computerized social cognition training (MRIGE), or CRT alone for 36 sessions...

BACKGROUND: Juvenile nasopharyngeal angiofibroma often attaches firmly to the adjoining bony region around the sphenopalatine foramina-sphenopalatine fossa-pterygomaxillary fissure. This can result in hourglass-shaped constriction and predispose to incomplete resection (residual disease) with a transpalatal approach. This paper describes attempts to address this 'inaccessible' area with a novel instrument, used since 2012. METHODS: Measurements of the sphenopalatine foramen, nasal septum, posterior nasopharyngeal wall and hard palate were undertaken in 20 skulls and 10 computed tomography scans (lateral extension)...
