The consequences of inflammatory response are primarily responsible for morbimortality in bacterial meningitis. Early use of steroids in these cases can reduce mortality and hearing loss and improve functional outcome without causing significant side effects. The formal recommendation towards pneumoccocal meningitis is being extended to other forms of Bacterial Meningitis. The same thought can be applied to tuberculous meningitis. In neurocysticercosis and neuroschistosomiasis steroids are more useful than parasiticides in most cases...

An 18-year-old man developed posterior reversible leukoencephalopaty after being bitten by a venomous snake (Bothrops asper). It is possible that this previously unrecognized neurological complication of snake bite envenoming occurred as the result of endothelial dysfunction induced by the venom of the offending snake. This pathogenetic mechanism has also been implicated as the cause of cerebral infarctions in snake bite victims. Alternatively, the leukoencephalopathy might have been a complication of antivenom therapy...

The introduction of highly active antiretroviral therapy does not seem to have altered the incidence of progressive multifocal leukoencephalopathy (PML) in HIV infection. Moreover, the occurrence of a HIV-related leukoencephalopathy, called not determined leukoencephalopaties (NDLE), has been reported. As neuropsychological impairment remains highly prevalent in HIV infection, the aim of this study is to describe the neuropsychological profile of PML and NDLE patients, analyzing the time-related changes. Clinical and neuropsychological data from 32 patients (17 PML, 15 NDLE) were compared with two control groups: (1) asymptomatic HIV+ patients without magnetic resonance imaging evidence of leukoencephalopathy; (2) age-/gender-/education-matched healthy subjects...

CASE REPORT: We report the clinical and radiologic observation in a man patient of 20 years old. He developed gravity left progressive facial hemiatrophy. In associated form, he presented numerous visual sensories and complex partials seizures. The single and combined treatment with several antiepileptic drugs was ineffective for the control of the epilepsy. The magnetic resonance investigation of the cranium facial structures showed the gravity and intensivity of the dysmorphia. The same procedure showed the strong of the duramadre atrophy in the convexity of the brain, as well as, the existence of the cystic formation in the white matter of the left temporo occipital region at the face affected...

CADASIL disease (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) was described in 1991 by Tourmier-Lasserve. Two years later the same authors described its association with chromosome 19; nonetheless, the mutations in gene Notch3 were not described until 1996. Clinical findings depend on the age at onset. The early form of the illness is found in young patients, generally less than 30 years old, and the main clinical manifestation is a migraine headache with subcortical lesions in the white matter, while in the later form ischemic events and behavioral symptoms are predominant...

Four cases of progressive multifocal leukoencephalopaty are reported, 3 of them with an ultrastructural study and 2 with a C.T. scan study. In 2 cases, there were no other associated pathological condition. In 1 case chronic alcoholism only was present; in the last case a primitive hemochromatosis with a prevailing hepatic dysfunction was evidenced. In 2 of these cases, the initial clinical picture was made of mental disorders while it was made of a progressive left hemiparesis in one case and of a brain stem syndrome in the other case...
