This paper is among the first to investigate the effect of a prior investment banking relationship on merger advisory fees paid by acquiring firms. We find that acquiring firms pay a higher fee to advisors when they have had a continuing relationship and a lower fee when they switch to an advisor with whom they have had no prior relationship. We develop a(More)
To investigate diagnostic value, therapeutic benefit and cost-effective utilization of video-EEG monitoring (VEM) in a comprehensive epilepsy program in a developing country. The authors prospectively recruited all patients who underwent long-term (> or =3 hours) inpatient VEM during a 10-month period. The cohort was followed to gather information about the(More)
BACKGROUND Focal cortical dysplasia (FCD) is often associated with epilepsy. Identification of FCD can be difficult due to subtle magnetic resonance imaging (MRI) changes. Though fluid-attenuated inversion recovery (FLAIR) sequence detects the majority of these lesions, smaller lesions may go unnoticed while larger lesions may be poorly delineated. (More)
PURPOSE To describe the clinical and electroencephalographic features, treatment strategies and outcome in a series of children with the atonic variant of benign childhood epilepsy with centrotemporal spikes (atonic-BECTS). MATERIAL AND METHODS Out of the 148 patients with BECTS reviewed from January 2005 to June 2010 in our Institute, there were seven(More)
BACKGROUND World-over, the majority of patients undergoing video-EEG monitoring (VEM) are in their second or third decades. Although elderly represent the fastest growing segment of population with epilepsy, only few of them undergo VEM. We critically evaluated the utility of VEM in the diagnosis and long-term management of older adults with paroxysmal(More)
PURPOSE To investigate the electro-clinical significance of premature accumulation of corpora amylacea (CoA) in the resected hippocampus of patients with medically refractory mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). METHODS We compared the clinical and EEG characteristics, and post-operative seizure outcome of 373 (mean age 29.4(More)

Guillain-Barré syndrome (GBS) is an acquired acute autoimmune polyradiculoneuropathy. The 2 features considered essential for the diagnosis of GBS are progressive motor weakness and areflexia. There have been several descriptions of reflex preservation and hyperreflexia in axonal variant of GBS in Chinese, Japanese, and European populations but it is not(More)
AIMS To assess the functional and clinical outcome in a sizeable cohort of patients with osmotic demyelination syndrome (ODS) and to characterise the factors which could predict the final outcome. METHODS Twenty five consecutive patients with ODS formed the study cohort. The diagnosis of ODS was based on clinical features with corroborating imaging(More)
