Mannitol was not superior to normal saline in relieving symptoms and signs of CP at 24 hours in this study population but had more side effects. These results do not support single-dose mannitol as standard treatment for CP.

We describe a new, severe variant of the still poorly defined postmalaria neurological syndrome. We propose a preliminary classification of this syndrome, according to its clinical characteristics, as follows: a mild or localized form, characterized by isolated cerebellar ataxia or postural tremor; a diffuse, but relatively mild encephalopathic form, characterized by acute confusion or epileptic seizures; and a severe, corticosteroid-responsive encephalopathy that is characterized by motor aphasia, generalized myoclonus, postural tremor, and cerebellar ataxia.

Three siblings in their sixth and seventh decade with hexosaminidase A and B deficiency (adult form of G,M-gangliosidosis, variant 0) developed early and severe sensory loss in addition to chronic motor neuron disease and cerebellar ataxia. Prominent mechanoallodynia was a manifesting symptom in two siblings. It is suggested that sensory deficits are due to a central-peripheral dying back axonopathy. The early and dominant sensory disturbances extend the clinical range of GM2-gangliosidosis.
