We examined the role of coagulation-fibrinolysis system in Theiler's murine encephalomyelitis virus-induced demyelinating disease (TMEV-IDD). The degree of fibrin deposition around the vessels in the spinal cord was significantly higher in susceptible SJL/J mice on 30 days post intracerebral injection (i.c.) than resistant C57BL/6 mice on 30 days post i.c. or mock infected SJL/J mice. Treatment with batroxobin (30 BU/kg/day), which is a thrombin-like defibrinogenating enzyme, causing a profound degree of afibrinogenemia, suppressed clinical signs of TMEV-IDD. Plasma fibrinogen concentration was significantly decreased in batroxobin-treated mice. Histologically, though the degree of perivascular mononuclear cell infiltration in the spinal cord was not suppressed in batroxobin-treated mice compared to saline-treated control mice, fibrin deposition was markedly suppressed in batroxobin-treated mice. These findings suggest that batroxobin suppresses TMEV-IDD through its defibrination effect, and provide evidence that CNS-associated deposition of fibrin and ensuing fibrinolysis, together with increased permeability of the blood-brain barrier (BBB), are prerequisite events for clinical manifestations of TMEV-IDD.

A 4-year-old boy was admitted with disturbed consciousness following a convulsion. He developed bilateral pyramidal tract signs and showed a decerebrate posture. Laboratory findings revealed severe liver dysfunction and disseminated intravascular coagulation. On the eighth day eight in hospital he developed parkinsonism. However, 5 months from onset he had recovered almost completely. Brain CT on admission showed low density areas in the basal ganglia, thalamus, midbrain and pons. A T2-weighted scan in magnetic resonance imaging (MRI) showed almost symmetrical high signal intensities in both basal ganglia (including putamen, caudate nucleus, globus pallidus), external capsule, internal capsule thalamus, midbrain, pons and white matter of the peribasal ganglia; but a T1-weighted scan showed low signal intensities in the same regions during all phases. Therefore hemorrhagic lesions or the presence of thalamic methemoglobin were excluded. It was considered that the pathogenesis may be cytotoxic cellular edema due to cytotoxic agents or acute metabolic factors. Clinical presentation, laboratory findings and radiological findings were most suggestive of acute necrotizing encephalopathy. As differential diagnoses, acute disseminated encephalomyelitis and brainstem encephalitis were considered.

This study investigated the clinical manifestations and outcomes of central nervous system (CNS) infection by enteroviruses. Cases with CNS involvement among all enterovirus-culture-positive cases from January 1995 to June 2003 were retrospectively reviewed. Among 1028 enterovirus-culture-positive cases, there were 333 cases involving the CNS. Of these, the ratio of male to female subjects was 1.78, and the mean (+/- standard deviation) age was 6.83 +/- 5.9 years; 21 were premature neonates, and 10 failed to thrive. Disease entities included 282 cases of aseptic meningitis (84.7%), 44 cases of encephalitis (13.2%), and 7 cases of encephalomyelitis/polio-like syndrome (2.1%). Of these cases, 97.9% (326/333) had fever with peak body temperature at 38.9 degrees C, 85% had headache and vomiting, 70% had meningeal signs, 64% had neck stiffness, 16.6% (55/333) had change of consciousness, 5.4% (18/333) had seizures and 5.2% (17/333) had myoclonic jerks. Mannitol was administered in 77.2% of patients (257/333), along with intravenous immunoglobulin in 6.6% (22/333). Twelve cases received ventilator support. One patient died of hand-foot-and-mouth disease, encephalitis plus cardiopulmonary failure, and 2 premature neonates died of hepatic failure, disseminated intravascular coagulation, sepsis-like syndrome and myocarditis. Eighteen had neurologic sequelae, including 7 with limb weakness, 5 with epilepsy, 2 with sixth cranial nerve palsy, 3 with cerebral palsy, 4 with psychomotor retardation, 2 with spasticity, and 1 with hearing loss. Factors associated with unfavorable outcomes (death or sequelae) included younger age (p=0.0003), higher peak white blood cell count (WBC) [p=0.0009] and skin rash (p=0.005). Younger age and higher peak WBC were poor prognostic factors of severe enterovirus CNS infection. Death was related to neonatal enterovirus infection and enterovirus 71 infection in young children.

Snake bite is an important cause of mortality and morbidity in India with an estimated 35 000-50 000 fatal bites occurring annually. Neurological deficits following vasculotoxic snake bite are either due to intracranial haemorrhage or subarachnoid bleed as a result of consumption coagulopathy. However, ischaemic strokes and acute disseminated encephalomyelitis have been reported occasionally. We hereby report a case of snake bite leading to leucoencephalopathy.
