In forty-five children the hypoxanthine concentration in cerebrospinal fluid (CSF) was measured (fifty-two samples). In newborn infants (nineteen patients) the hypoxanthine levels were higher in patients with clinical conditions associated with hypoxia (idiopathic respiratory distress syndrome, asphyxia, apneic attacks) than in patients without clinical hypoxia (P less than 0.01). In hypoxic patients the hypoxanthine concentration varied between 5 and 28 mu mol/l. In children outside the neonatal period the hypoxanthine concentration in CSF varied considerably in different diseases. High levels were registered in meningitis prior to treatment, febrile convulsions and in lymphoblastic leukaemia, probably reflecting tissue hypoxia and an increased tissue catabolism.

Cerebrospinal fluid (CSF) was analysed to determine a lumbar puncture (LP) yield for meningitis in 95 children who presented with their first febrile convulsions between July 1993 and June 1994. There were 52 males and 43 females aged six months to six years with a mean age of 21.9 +/- 13.0 months at presentation. 87(91.6%) had simple febrile convulsions (SFC) while the remaining 8(8.4%) had complex febrile convulsions (CFC). The majority of the subjects presented with a sudden onset of convulsions that were preceded by a day or two history of fever, coryza, cough and respiratory distress while others had their convulsions preceded by fever and passage of bloody stools. The LP yield for meningitis in this series was 6.3%. The CSF analysis revealed six cases of meningitis comprising an eight month old infant with Haemophilus influenzae type B (HIB) meningitis, two partially treated pyogenic meningitis and three aseptic meningitis. All of them had presented with febrile convulsions without signs of meningeal irritation. Excluding aseptic meningitis from this series, a 3.1% LP yield for pyogenic meningitis is significant enough to recommend continued performance of LP in children with first febrile convulsions, especially if under the age of eighteen months.

The novel pandemic (pdm) influenza A (H1N1) 2009 virus caused an epidemic of critical illness, with some patients developing severe acute respiratory distress syndrome. Pdm H1N1 2009 infection has been reported to cause fatal encephalopathy and myocarditis as well as pneumonia. To investigate the actual characteristics of the encephalopathy associated with pdm H1N1 2009 infection in Japan, questionnaires were distributed and information collected on 207 cases of encephalopathy during one season. The results of the survey showed that encephalopathy was reported predominantly in males. The outcome was recorded in 188 of the 207 cases; 16 of 188 patients (8.5%) died, while 23 (12.2%) had sequelae. Serious cases were distributed across all age groups. Febrile convulsion was noted at a higher rate in medical past-history in cases without sequelae (40 of the 149 cases; 27%) than in serious cases. In contrast, pre-existing epilepsy and mental retardation were observed more frequently in serious cases. Twelve cases exhibited biphasic seizures; one-half of these had sequelae, but none was fatal. Ten cases were accompanied by high cytokine levels, and three of these children died. Among the 149 cases with good outcomes, 29 of 116 cases (25%) showed abnormalities on MRI, and 14 of these demonstrated reversible splenial lesions. Abnormal behaviors, especially delirium and visual hallucinations, were observed more frequently in cases without sequelae. In conclusion, pdm H1N1 2009 infection-associated encephalopathy was a critical disease in children, with rapidly progressive characteristics similar to those of seasonal influenza-associated encephalopathy.

Strains of human coronavirus (HCoV), namely HCoV-OC43, HCoV-229E, HCoV-NL63, and HCoV-HKU1, primarily infect the upper respiratory and gastrointestinal tracts and are the most common cause of non-rhinovirus-induced common cold in humans. Although the manifestations of coronavirus infection (i.e., rhinorrhea, sneezing, cough, nasal obstruction, and bronchitis) are generally self-limiting in healthy adults, certain strains such as HCoV-NL63 and HCoV-HKU1 can cause severe lower respiratory tract infection and febrile seizure, especially in infants, people of advanced age, and immunocompromised hosts. In 2003, a novel HCoV strain was identified as the causative agent of the severe acute respiratory syndrome (SARS) epidemic that began in Asia in 2002. The strain has hence been referred to as SARS-CoV. In addition, as recently as September 2012, another novel HCoV, human betacoronavirus 2c EMC2012, was identified as being the cause of fever, renal failure, pneumonia, and severe respiratory distress in two patients in the Middle East. Phylogenetic analysis has revealed highly conserved sequences of ORF1ab, spike, nucleocapsid, and envelope protein genes, but not membrane protein genes, between human betacoronavirus 2c EMC2012 and SARS-CoV. This review focuses on the differences in the genomes of certain HCoV strains, the pathogenesis of said strains, and recent developments in the establishment of therapeutic agents that might aid in the treatment of patients with such infections.
