1/39. SSPE following neonatal measles infection.The authors report a case of subacute sclerosing panencephalitis in a child who had measles during the neonatal period. At 3 years, 6 months of age, over a period of a few weeks, the patient lost the ability to sit unaided as a result of progressive truncal ataxia, without apparent cognitive changes, simulating acute cerebellar ataxia. His symptoms improved in 1 month, and he was able to walk again with support, but mental alteration and periodic mild head nodding on awakening followed. His illness was diagnosed as subacute sclerosing panencephalitis on the basis of the elevated titers of measles antibodies in the cerebrospinal fluid. Measles infection before 1 year of age is a risk factor of subacute sclerosing panencephalitis, but reports about patients with neonatal measles infection are rare. Immaturity of the brain at the time of measles infection may not only be a risk factor but may also influence the clinical course of the disease.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/39. Acute disseminated encephalomyelitis with probable measles vaccine failure.The patient is a 10-year-old male who experienced somnolence and incomplete quadriplegia after headache and vomiting, without exanthema, for 3 days. The clinical course and magnetic resonance imaging findings of the brain and spinal cord were compatible with acute disseminated encephalomyelitis. The serologic examination revealed that the patient had rubeola because titers of IgM and IgG antibody to measles virus measured by enzyme immunoassay were 0.91 and 40 (cutoff = 0.80 and 2), respectively, at 5 weeks after the onset, the IgM titer had become negative (0.56), and the IgG titer had decreased to 17.7 at 13 weeks after the onset. Because the patient had received a measles-mumps-rubella vaccine at 12 months of age, the acute disseminated encephalomyelitis was thought to be attributed to the modified measles resulting from measles vaccine failure.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
3/39. Subacute encephalopathy in a 5-year-old boy.A 5-year-old boy presented with an acute ataxia and altered mental status. Although he initially recovered from these symptoms, he presented a second time with myoclonus and seizures and rapidly became vegetative. cerebrospinal fluid studies, magnetic resonance imaging, and brain biopsy all confirmed the presence of subacute sclerosing panencephalitis. Despite courses of therapy with cimetidine, amantadine, ribavirin, and inosine, no clinical improvement has been seen. Clinicians need to be alert to the possibility of subacute sclerosing panencephalitis even in the vaccinated child in the appropriate clinical setting.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
4/39. Measles inclusion-body encephalitis caused by the vaccine strain of measles virus.We report a case of measles inclusion-body encephalitis (MIBE) occurring in an apparently healthy 21-month-old boy 8.5 months after measles-mumps-rubella vaccination. He had no prior evidence of immune deficiency and no history of measles exposure or clinical disease. During hospitalization, a primary immunodeficiency characterized by a profoundly depressed CD8 cell count and dysgammaglobulinemia was demonstrated. A brain biopsy revealed histopathologic features consistent with MIBE, and measles antigens were detected by immunohistochemical staining. Electron microscopy revealed inclusions characteristic of paramyxovirus nucleocapsids within neurons, oligodendroglia, and astrocytes. The presence of measles virus in the brain tissue was confirmed by reverse transcription polymerase chain reaction. The nucleotide sequence in the nucleoprotein and fusion gene regions was identical to that of the Moraten and Schwarz vaccine strains; the fusion gene differed from known genotype A wild-type viruses.- - - - - - - - - - ranking = 2keywords = brain (Clic here for more details about this article) |
5/39. Acute transient pseudoatrophy of the brain accompanying measles infection.Two infants, age 1 year, with acute encephalopathy who showed transient pseudoatrophy of the brain were reported. They each had measles infection, followed by 'mild drowsiness'. Reversible brain atrophy has been observed in patients with undernutrition, dehydration, and overdoses of steroids and valproic acid. However, these manifestations were very mild and there was no history of drug administration in our patients. The cause of the transient brain pseudoatrophy was unknown. However, activation of glial cells accompanying the measles infection was thought to be one possibility to see high value of neopterin (51 pmol/l) in the cerebrospinal fluid in one case. Although 'mild drowsiness' is not a rare manifestation in patients with measles infection, it is probable that their 'mild drowsiness' is caused by acute encephalopathy like in our cases. Thus, we recommend that computed tomography scanning or magnetic resonance imaging is performed in patients showing 'mild drowsiness' during measles infection.- - - - - - - - - - ranking = 7keywords = brain (Clic here for more details about this article) |
6/39. Subacute measles encephalitis in an immunocompetent adult.subacute sclerosing panencephalitis (SSPE) and subacute measles encephalitis (SME) are both rare complications of measles virus infection. SSPE typically affects immunocompetent children, has an insidious onset and follows a steadily progressive course. SME mainly occurs in immunosuppressed children and has a rapidly progressive course. We describe a 43 year old immunocompetent man who presented with a rapidly progressive fatal encephalopathy. Histological examination of the brain showed a meningoencephalitis with inclusion bodies. Complement fixing antibody to measles virus was present in his serum and CSF. measles virus rna was found in the brain, spinal cord and eye, but not in the CSF. Analysis of the nucleoprotein gene isolated from this patient did not show similarity to SSPE strains of the measles virus. This patient demonstrates that subacute encephalitis secondary to measles virus infection can develop in an immunocompetent adult host.- - - - - - - - - - ranking = 2keywords = brain (Clic here for more details about this article) |
7/39. Bilateral anterior optic neuritis in adult measles infection without encephalomyelitis.PURPOSE: To describe anterior optic neuritis in adult measles infection.DESIGN: Interventional case report. methods: A 31-year-old woman presented with bilateral visual loss 6 days after the onset of maculopapular rash. Complete ophthalmic and neurologic examinations, radiologic studies, and lumbar puncture were performed. RESULTS: Visual acuities were counting fingers in both eyes, with bilateral optic disk hyperemia and swelling noted. neurologic examination was unremarkable, and computed tomography and magnetic resonance imaging of the brain were normal. The cerebrospinal fluid (CSF) was devoid of white cells, although measles immunoglobulin m (IgM) antibodies were detected in both CSF and serum. Intravenous corticosteroids were administered, and clinical findings resolved within 1 month. A fall in serum IgM and a rise in serum IgG titers were observed. CONCLUSIONS: Although rare, optic neuritis in the absence of encephalomyelitis may occur in measles. Whether treatment is effective is unknown.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
8/39. Severe infantile measles encephalitis occurred three months after neonatal measles.A 3-month-old girl who developed severe measles encephalitis after neonatal measles is reported. Her mother had measles when she was ten days old and she was admitted to our hospital with low grade fever, Koplik spot, and mild exanthema seventeen days after birth, and she recovered in 7 days without any complication. At three months of age, she was readmitted because of intractable seizures. The levels of IgM and IgG antibodies against measles in the cerebrospinal fluid were elevated. The measles virus genome, amplifying the region encoding the nucleocapsid protein, was detected from the brain specimen by reverse transcriptase-polymerase chain reaction. magnetic resonance imaging showed a focal destructive lesion and diffuse cerebral atrophy. The electroencephalogram did not show periodic synchronous discharges. Although the neonatal measles was believed to be relatively mild in severity, the possible development of measles encephalitis should be carefully monitored in an infant who had neonatal measles.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
9/39. Long-term findings on brain magnetic resonance imaging in acute encephalopathy with bilateral striatal necrosis associated with measles.The long-term findings on brain magnetic resonance imaging (MRI) in a 7 10/12-year-old boy with a history of acute encephalopathy with bilateral striatal necrosis following measles at the age of 22 months are described. At the early stage of illness, brain MRI studies revealed bilateral, symmetric basal ganglia lesions, predominant on the globi pallidi, appearing as hyperintense signals on T1- and T2-weighted images. Six years later, follow-up brain MRI studies showed that the bilateral, symmetric lesions on the globi pallidi persisted with low signal on T1- and high signal on T2 weighted images. At present, the patient has some persistent neurologic signs. These findings suggest that both clinical and neuroradiologic findings may persist in children with acute encephalopathy with bilateral striatal necrosis following measles.- - - - - - - - - - ranking = 7keywords = brain (Clic here for more details about this article) |
10/39. Encephalopathy following measles infection in children with chronic illness.Five patients with an unusual encephalopathy, possible secondary to measles virus infection, are described. Features common to these patients are: an existing chronic disease, neurologic deterioration 2 1/2 to 6 months after a measles infection, and death several weeks later. These events occurred when the chronic disease (e.g. leukemia or neuroblastoma) was in remission. That the measles virus was the causative agent is suggested only by finding in brain and extracranial tissues intracytoplasmic and intranuclear inclusions which contained measleslike particles. Additional clinical features seen in each of the five patients were: seizures, hypertension, and the inappropriate secretion of antidiuretic hormone.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
