Neonates with this distinctive DWI pattern had a high positive rate of rotavirus infection, without evidence of other pathogens, and were characterized as term newborns with neurologic symptoms arising approximately the fifth day after birth. Although the specificity of this pattern is unclear, rotavirus testing should be considered for neonates presenting with this DWI pattern.
Our study recommended that serum sodium be monitored regularly in patients taking OXC, especially in old age, AED polytherapy or concomitant use of diuretics, to assist in the early recognition of hyponatremia and to increase the awareness of symptoms that might be attributable to this.
The antibiotic resistance rates of H. pylori in Jinju had a different pattern to other regions. The antibiotic resistance rates of H. pylori showed geographic variation, and local data should be provided as a guideline for treating H. pylori infection.
Background and PurposeHerpes simplex encephalitis (HSE) is the most common type of sporadic encephalitis worldwide, and it remains fatal even when optimal antiviral therapy is applied. There is only a weak consensus on the clinical outcomes and prognostic factors in patients with HSE. This study examined whether the radiological and electrophysiological findings have a prognostic value in patients with HSE.MethodsWe retrospectively analyzed patients who were diagnosed with HSE by applying the polymerase chain reaction to cerebrospinal fluid and who received intravenous acyclovir at our hospital from 2000 to 2014. We evaluated the clinical outcomes at 6 months after onset and their correlations with initial and clinical findings, including the volume of lesions on MRI, the severity of EEG findings, and the presence of epileptic seizures at the initial presentation.ResultsTwenty-nine patients were enrolled (18 men and 11 women). Univariate analysis revealed that the presence of severe EEG abnormality and epileptic seizures at the initial presentation were significant correlated with a poor clinical outcome at 6 months (p=0.005 and p=0.009, respectively). In multivariate analysis, the presence of severe EEG abnormality was the only independent predictor of a poor outcome at 6 months (p=0.006).ConclusionsIn cases of HSE, the initial EEG severity and seizure presentation may be useful predictive factors for the outcome at 6 months after acyclovir treatment.
Kawasaki disease (KD) is an acute febrile illness that is the predominant cause of pediatric acquired heart disease in infants and young children. Because the diagnosis of KD depends on clinical manifestations, incomplete cases are difficult to diagnose, especially in infants younger than 1 year. Incomplete clinical manifestations in infants are related with the development of KD-associated coronary artery abnormalities. Because the diagnosis of infantile KD is difficult and complications are numerous, early suspicion and evaluation are necessary.
Rotavirus infection disturbs cellular Ca(2+) homeostasis by triggering an increase in Ca(2+) permeation. A theoretical link between Ca(2+) dysregulation and seizures in patients with rotavirus gastroenteritis has been suggested, but no prior studies have investigated this relationship. To test our hypothesis that patients with rotavirus-associated seizures have greater Ca(2+) homeostasis disruption than those without seizures, we compared clinical and laboratory data--including corrected total serum Ca(2+) levels--between the 2 groups. Age, gender, maximum body temperature, day of admission, levels of electrolytes except Ca(2+), blood pH, and urine ketone levels were not related to seizure occurrence. Significantly lower Ca(2+) levels were found among the seizure (+) group (9.22 ± 0.50 vs 9.66 ± 0.46 mg/dL, P = .01). Although Ca(2+) levels were within normal ranges and did not directly cause the seizures, our results provide preliminary evidence for a relationship between Ca(2+) homeostasis disruption and seizures in rotavirus patients.
PurposeHuman parechovirus (HPeV) and enterovirus (EV) are causative agents of a sepsis-like illness in neonates and of infections of the central nervous system in young children. The objectives of this study were to assess the prevalence of HPeV3 and EV infection in young children with a sepsis-like illness or with meningitis in Jinju, Korea.MethodsCerebrospinal fluid (CSF) samples were collected from 267 patients (age range, 1 day to 5 years) and assessed for HPeV and EV by performing reverse transcription polymerase chain reaction assay. Amplification products of the VP3/VP1 region of HPeV and of the VP1 region of EV were sequenced to identify the virus type.ResultsHPeV and EV were detected in 3.4% and 7.5% of the total CSF samples assessed, respectively. The age distribution of EV-positive patients (median age, 1.4 months) had a significantly broader range than that of HPeV-positive patients (median age, 7.8 months). The peak seasons for HPeV and EV infection were spring and summer, respectively. The clinical symptoms for HPeV and EV infection were similar, and fever was the most common symptom. Pleocytosis was detected in 22.2% of HPeV-positive patients and 35.5% of EV-positive patients. The VP3/VP1 gene sequence of the nine Korean strains clustered most closely with the Japanese strain (AB759202).ConclusionThe data indicate that HPeV infection is predominant in young infants (<6 months) and that meningitis without pleocytosis was caused by both HPeV and EV infection in children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
