Its induction by enteroviruses (EVM) is associated with morbidity and is primarily diagnosed by lumbar puncture, which may yield false negatives. We evaluated the frequency of VM by polymerase chain reaction (PCR) among infants with no detected pleocytosis. Furthermore, as literature suggests EVM essentially occurs during summer and fall, we characterized the monthly distribution of EVM cases. Methods:?Infants diagnosed with VM from June 2009 to May 2010 were enrolled in the current prospective study. Following each lumbar puncture, CSF was tested for enteroviruses by PCR. Outcome measures were i) the percentage of EVM cases revealed solely by PCR;and ii) the monthly distribution of EVM cases. Results:Enrolled were 173 VM-diagnosed infants, of whom 75 (43.4%) tested positive in CSF-PCR. Of these, no pleocytosis was indicated in 43 (57%), specifically in 70% and 42% of infants younger than 90 days and older than 1 year, respectively. Furthermore, 119 (69%) infants were admitted during June-November while 54 (31%) during December-May. Conclusions:Current findings stress the high frequency of infants who were tested negative for pleocytosis, yet were diagnosed with VM by PCR. This was especially noticeable among infants younger than 3 months, possibly reflecting their decreased ability to mount a robust inflammatory response to EV infection. CSF-PCR may be warranted in pediatric patients who test negative for pleocytosis. While most EVM cases occurred during the summer and fall, EVM-infants were admitted to the hospital all through the year.展开更多

It is a deadly and enfeebling disease that affects people of all ages and most often caused by a bacterial or viral infection. Bacterial meningitis is a more serious and life-threatening condition, while viral meningitis the most frequent kind is often less severe and self-limiting. Therefore, successful treatment of meningitis depends on identifying the suspected or known causative organism. In this article, we aim to review the latest information about the etiology of meningitis and explore its possible occurrence and complication followed COVID-19 infection.展开更多

Design: Retrospective cohort study. Methods: Patients who had severe viral meningitis combined with respiratory failure, were admitted to the hospital from March 2017 to June 2018, and who received the WeChat-based nursing intervention were included. Patients who received routine nursing were used as controls. The family’s emotional state, self-care ability, and rehabilitation were analyzed. Results: There were 37 patients in the WeChat group (19 boys (51.3%) and 18 girls (48.7%);mean of 5.1 ± 2.4 years of age) and 37 controls (20 boys (54.1%) and 17 girls (45.9%);mean of 5.9 ± 2.4 years of age) (all P > 0.05). After nursing, improvements in the self-assessed anxiety score and self-assessed depression score were better in the WeChat group (anxiety: -29.2% vs. -20.3%, P = 0.015;depression: -25.2% vs. -15.4%, P = 0.009). After nursing, the improvements in the condition management ability scale and condition management difficulty scale scores were better in the WeChat group (ability: +80.5% vs. +44.4%. P = 0.001;difficulty: +58.4% vs. +37.8%, P = 0.003). After nursing, the improvement in the Fugl-Meyer score was better in the WeChat group (+138.0% vs. +53.0%, P Conclusion: Early nursing intervention combined with WeChat peer education can improve the emotional state of children with severe viral meningitis combined with respiratory failure and their caregivers. Impact: Viral meningitis is associated with a good prognosis, but central nervous system complications can be observed. Early intervention is the key to a good prognosis. Internet-based nursing and coaching can improve self-efficacy and care ability in patients with various conditions, as well as improve the emotional state of the children and their caregivers. The research might have an impact on any children’s hospital that deals with viral meningitis.展开更多
