Brain abscess: With special reference to infection by pseudomonas
(Informa Healthcare, 1990) Sunil K. Gupta; Sureshwar Mohanty; Shiv C. Tandon; Sanjay Asthana
Eighty cases of brain abscess treated in the University Hospital, BHU, Varanasi, India have been reviewed. Chronic suppurative otitis media was the commonest cause, followed by compound injuries. The overall mortality was 15% In seven cases the causative organism was pseudomonas, resistant to most antibiotics. Prior to the availability of CT the mortality was 23.3%; after the routine use of CT for diagnosis the mortality fell to 10% A high mortality (57% was observed in patients who had pseudomonas. The best results were in patients who had been managed by excision of the abscess capsule. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
Judgment of facial expression of emotion in unilateral brain-damaged patients
(1993) Manas K. Mandal; Hari S. Asthana; Shiv C. Tandon
Patients with unilateral brain damage and normal controls were asked to give (1) inter-emotion judgment within the photographs of six facial emotions in terms of mutual similarities, and (2) intra-emotion judgment within the hemifacial composite photographs of an emotion in terms of intensity of expression. Right brain-damaged patients could differentiate between the emotion of happiness and all other emotions. Left brain-damaged patients differentiated between aroused-nonaroused emotions. Normal controls differentiated between positive-negative as well as aroused-nonaroused emotions. Left-left facial composites were judged to have expressed more intensely than right-right facial composites or normal/mirror-reversed facial orientations of emotions (except fear) by any group (p > .05). © 1993.
Matching top-bottom parts of facial expressions by brain-damaged patients
(1991) Hari S. Asthana; Manas K. Mandal; Shiv C. Tandon; Sanjay Asthana
Patients with focal brain-damage, right/left hemisphere-damage (RHD/LHD) and anterior/posterior region-damage (ARD/PRD), and normal controls (NC) were asked to match photographs of top-bottom facial parts expressing different emotions, positive (happy, surprise), negative-aroused (fear, anger), negative-nonaroused (sad, disgust). The LHD patients performed significantly worse than the RHD patients, and the ARD patients were significantly worse than the PRD patients, in the perceptual-matching task with affective stimuli. NC subjects performed significantly better than any of the brain damaged sub-groups. © 1991 Rapid Communications of Oxford Ltd.
