Polysplenia, as part of the heterotaxy syndrome, is a rare embryological disorder which results from failure of development of the usual left-right asymmetry of organs. It is often associated with cardiac and biliary abnormalities, which are the usual causes of death in early neonatal life. A congenitally short pancreas and abnormalities with portal vein(More)
OBJECTIVE To investigate whether intensification of combined antiretroviral therapy (cART) with the CC chemokine receptor type 5 (CCR5) entry inhibitor maraviroc leads to improvement in global neurocognitive functioning in virally suppressed men with HIV-associated neurocognitive disorder (HAND). DESIGN Prospective, double observer-blinded, open-label(More)
BACKGROUND Pathophysiological basis of Magnetisation Transfer Ratio (MTR) reduction in multiple sclerosis still remains a matter of controversy. Optic nerve represents an ideal model to study the consequences of axonal loss and demyelination on MTR since effects of disease on the optic nerve are clinically apparent and potentially quantifiable by objective(More)
We present two cases of recurrent progressive multifocal leukoencephalopathy (PML) in patients with long standing virally suppressed human immunodeficiency virus (HIV) and normal CD4+ T cell count who were taking stable regimens of highly active antiretroviral therapy (HAART). This has significant implications for other patients with a past history of PML,(More)
Conventional magnetic resonance imaging (MRI) is the technique of choice for diagnosis of cerebral tumours, and has become an increasingly powerful tool for their evaluation; however, the diagnosis of common contrast-enhancing lesions can be challenging, as it is sometimes impossible to differentiate them using conventional imaging. Histopathological(More)
OBJECTIVE The purpose of this case study is to describe the case of a person with agenesis of the corpus callosum (ACC), intellectual disability and features of antisocial behaviour and lying. METHODS A 26-year-old woman with a mild intellectual disability who presented with antisocial behaviour and chronic lying was found to have ACC and associated(More)
We report a patient with a large infratentorial neurenteric (NE) cyst. Intracranial NE cysts, also known as enterogenous cysts, constitute a rare, generally benign entity of unknown aetiology. The presentation, imaging characteristics and management of the case is discussed, including illustrative peri-operative images.
Lasting taste disturbance has been previously reported as a consequence of brainstem infarction, but there are no previous reports of transient gustatory sensations preceding the onset of stroke. Ophthalmodynia, presenting as "salt-and-pepper" eye pain, has been reported rarely. We present a 58-year-old right-handed woman who had fluctuating ophthalmodynia(More)
