BACKGROUND Although electroconvulsive therapy (ECT) causes no structural brain damage, recent studies reported altered brain perfusion acutely following ECT. This is in keeping with brain edema which was noted in animal experiments following electroconvulsive shock. AIM This study examined alteration in magnetic resonance imaging (MRI) T(2) relaxation(More)
BACKGROUND Evidence suggests that caudate nucleus abnormalities have a role in schizophrenia. Structural brain imaging studies on caudate size in schizophrenia are inconclusive due to confounding factors. METHODS In this study, caudate volume was measured on coronal Magnetic Resonance Images (I -mm) in consenting 15 never-treated schizophrenia (DSM-IV)(More)
The aim of the study was to detect brain oedema with electroconvulsive therapy (ECT). Magnetic resonance imaging (MRI) T(2) relaxation time which is an indicator of brain water was measured one day prior to the first ECT and at two hours after second ECT in five depressive patients prescribed right unilateral (RUL) ECT. MRI T(2), relaxation time was(More)
The authors describe an infant with Down's syndrome who had a prepyloric web complicated by severe gastric outlet obstruction. The delay in diagnosis was responsible for malnutrition and the early postoperative complications of hypothermia and hypoglycemia. Awareness of the association of gastrointestinal abnormalities with Down's syndrome will enable(More)
We present a 62-year-old lady admitted in our hospital with two episodes of acute ischemic stroke about 2 weeks apart. She was evaluated for acute ischemic stroke and was thrombolysed for recent stroke in right MCA territory first time. On further evaluation, she was found to have a RVOT mass. A transthoracic and transesophageal echocardiogram revealed a(More)
