Nitrite/nitrate (NOx) and zinc concentrations in influenza-associated encephalopathy in children with different sequela.

NOx (NO2 and NO3) in CSF obtained from 22 patients with influenza-associated encephalopathy were higher than those of a control group. Within the different prognosis, there were no significant differences in NOx levels. By analyzing the serum obtained from patients infected with influenza, including encephalopathy, with others, the serum zinc levels did show marked differences between them.

Enteroviral hepatitis in children.

Background: The pathogen causing enteroviral hepatitis is often not found despite careful examination.

Methods: This study investigates the enterovirus genome in serum and liver tissue obtained from patients who showed abnormal liver function without negative data of usual studies and cytomegalovirus (CMV) serologically positive cases.'

Results: Nine out of 21 serum samples were positive by using reverse transcriptase-polymerase chain reaction (RT-PCR) for enterovirus.

Clinical characteristics and gB genotype of cytomegalovirus infection in Japan.

To investigate the role of cytomegalovirus (CMV) gB genotypes, we examined the relationship between gB genotypes and clinical features in 19 patients with CMV infection. We analyzed 9 immunocompetent patients (1A) and 5 patients (1B) with various basic disorders in the symptomatic group. Five patients were enrolled in the asymptomatic group (2).
