We reviewed retrospectively the clinical records, autopsy protocols and central nervous system tissue sections of 50 patients who underwent orthotopic liver transplantation for end-stage liver disease between 12/83 and 8/93. The postoperative survival period ranged from hours (6), weeks (17), months (17), to years (10). All patients received immunosuppressive drugs from the immediate postoperative period to the time of their death (cyclosporine, steroids; occasionally azathioprine, OKT3, FK506). Nineteen patients had neurological manifestations (hepatic encephalopathy) prior to surgery. Post-transplant neurologic signs and symptoms included: hepatic encephalopathy/altered mental status (11), focal or generalized seizures (9) and stroke (2). In the majority of cases (37) the cause of death was septicemia and/or bleeding diathesis. The neuropathologic findings present in 36 patients could be classified into 3 distinct categories: metabolic disorders: hepatic/anoxic encephalopathy, central pontine myelinolysis (15); cerebrovascular disease: subarachnoid and/or intracerebral hemorrhage, bland or hemorrhagic infarction (23); and infection: bacterial meningitis/cerebritis, multifocal fungal microabscesses, presumptive viral meningitis/encephalomyelitis (10). In conclusion, 72% of 50 patients who came to autopsy after liver transplantation were found to have neuropathologic abnormalities; these abnormalities were predominantly infections and vascular diseases.

A retrospective study of serum and cerebrospinal fluid (CSF) samples collected from suspected viral encephalitis and encephalopathy cases was carried-out and it included 100 CSF and 89 serum samples from Goa, collected during 1990-1994. These samples which were negative for antibodies to Japanese encephalitis (JE), West Nile (WN), Dengue-2 (DN-2) and herpes viruses, were tested for Coxsackievirus B 4 specific antibodies by 'in vitro' microneutralization technique along with 80 negative control serum samples. Out of 189 specimens (100 CSF and 89 serum), 23 CSF and 41 serum samples were positive for Coxsackievirus B 4 neutralizing antibodies. Antibody profile seemed to be IgG as revealed by mercaptoethanol treatment. The presence of neutralizing antibodies to coxsackievirus B 4 with titres as high as 1:512 in 8 CSF and 19 serum samples seemed to be suggestive of viral meningitis due to Cox B-4 viruses.

Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of the central nervous system (CNS) that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalopathy. ADEM is considered an autoimmune disorder that is triggered by an environmental stimulus in genetically susceptible individuals. The diagnosis of ADEM is based on clinical and radiological features. Most children with ADEM initially present with fever, meningeal signs, and acute encephalopathy. The level of consciousness ranges from lethargy to frank coma. Deep and subcortical white-matter lesions and gray-matter lesions such as thalami and basal ganglia on magnetic resonance imaging (MRI) are associated with ADEM. In a child who presents with signs of encephalitis, bacterial and viral meningitis or encephalitis must be ruled out. Sequential MRI is required to confirm the diagnosis of ADEM, as relapses with the appearance of new lesions on MRI may suggest either multiphasic ADEM or multiple sclerosis (MS). Pediatric MS, defined as onset of MS before the age of 16, is being increasingly recognized. MS is characterized by recurrent episodes of demyelination in the CNS separated in space and time. The McDonald criteria for diagnosis of MS include evidence from MRI and allow the clinician to make a diagnosis of clinically definite MS on the basis of the interval preceding the development of new white matter lesions, even in the absence of new clinical findings. The most important alternative diagnosis to MS is ADEM. At the initial presentation, the 2 disorders cannot be distinguished with certainty. Therefore, prolonged follow-up is needed to establish a diagnosis.
