Longitudinally extensive dorsal column spinal cord lesion with sensory ganglionopathy.

We present a case of a 23-year-old woman with a history of celiac disease who presented with a 2-month history of progressive gait unsteadiness and falls. Neurologic examination exhibited preserved motor strength, diffuse areflexia, and ataxic gait. Autoimmune and infectious workups were unremarkable, including vitamin B12.

The use of eculizumab in ventilator-dependent myasthenia gravis patients.

Introduction/aims: Eculizumab has been shown to be efficacious in acetylcholine receptor antibody-positive (AChR ) Myasthenia Gravis Foundation of America (MGFA) class II, III, and IV generalized myasthenia gravis (gMG) patients. However, it has not been studied in MGFA class V gMG patients.

Methods: We report three AChR , refractory, MGFA class V gMG patients treated with eculizumab.

Rituximab in refractory chronic inflammatory demyelinating polyneuropathy.

Introduction: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a disorder in which early effective treatment is important to minimize disability from axonal degeneration. It has been suggested that some patients with CIDP may benefit from rituximab therapy, but there is no definitive evidence for this.

Methods: Baseline and post-rituximab-therapy neuromuscular Medical Research Council (MRC) sum scores, Inflammatory Neuropathy Cause and Treatment (INCAT) disability score, and functional status were assessed in 11 patients with refactory CIDP.

Post-infarct cerebellar cognitive affective syndrome: a case report.

Post Infarct cerebellar cognitive affective syndrome is a rare disorder, characterized by cognitive impairment in the domains of memory, language, visuo-spatial functioning and affect after cerebellar stroke. We report a case of young female who developed mood alteration and cognitive disturbance following isolated cerebellar infarct. We, therefore, advocate a potential role of cerebellum in regulation of cognition and behaviour in humans.

Mechanism of neuronal injury in cerebral venous thrombosis.

The impact of CVT on the brain is wide spectrum, ranging from completely normal parenchyma to brain oedema and/or haemorrhage. Multiple factors relate to neuronal injury in CVT including; dural sinus pressure, increased venous flow velocities, collateralization of venous channels, rate of occlusion, development of cytotoxic and vasogenic oedema, recanalization and accelerated myelination. It is suggested that recanalization of occluded vein, as well as, the presence or absence and the efficiency of intracranial venous collaterals, may have an impact on the extent of brain tissue damage and hence the prognosis of acute CVT.

Rapidly developing optic neuritis secondary to ethambutol: possible mechanism of injury.

Optic neuritis has been described among the toxic effects of Ethambutol. This side effect is dose related. The mean duration of Ethambutol induced optic neuritis (EON) is three months.
