  • Purpose : The purpose of this study was to describe the epidemiologic features of febrile illnesses in newborns and to predict the risk of serious infections in this population. Methods : A retrospective study was conducted on 123 full-term infants <30 days of age with an axillary temperature >38$^{\circ}C$ who were hospitalized between 2000 and 2006. Neonates with prenatal risk factors, congenital anomalies, antibiotic administration prior to admission to the hospital, or suspected hospital-acquired infections were excluded. We evaluated the symptoms, physical examination findings, laboratory data, and clinical course between the high- and low-risk groups for serious infections. Results : The high-risk group included 30 infants with the following diagnoses in order of frequency: aseptic meningitis, urinary tract infection, bacterial meningitis, infectious enteritis, sepsis concomitant with disseminated intravascular coagulopathy, bacteremia, pneumonia, cellulitis, and omphalitis. Leukocytosis and thrombocytopenia were statistically different between the two groups. Factors, such as moaning signs, seizures, body temperature, and pulse rate were statistically significant. Conclusion : Unlike previous studies, we included newborns with clinical bacterial infections and aseptic meningitis as the high-risk group. Leukocytosis, thrombocytopenia, moaning signs, seizures, and changes in vital signs were considered useful predictors for identifying febrile neonates at high-risk for serious infections in spite of a difference in the definition of serious infection.

  • Purpose : As several epidemics of aseptic meningitis had been reported in Korea since 1990, the need of epidemiologic study about enteroviral infections was recognized. We studied epidemiologic and clinical features of enteroviral infections in children. Methods : We analyzed the seasonal occurrence of enteroviral infections and age, sex and clinical diagnosis of the children admitted to five branch hospitals of Hallym University and diagnosed to have enteroviral infections by culture from January 1996 to December 1998. Results : Enterovirus was isolated in 126 out of 245(51.4%) stools, 15 out of 89(16.8%) nasopharyngeal aspirates and 195 out of 1,835(10.6%) cerebrospinal fluids. There were 273 echoviruses(Echo)(197 Echo 30, 46 Echo 9, 17 Echo 6, 13 unclassified), 24 coxsackieviruses B(CB)(11 CB 2, 2 CB 5, 11 unclassified), 7 coxsackieviruses A 24 and 32 unclassified enteroviruses. Yearly number of isolates was 65(46 Echo 9) in 1996, 239(197 Echo 30) in 1997 and 32(15 CB: 9 CB 2) in 1998. Epidemics of enteroviruses occurred mainly during the months May to October. The mean age of the infected children was $62.1{\pm}38.0$ months and 74.6% of the patients were younger than 7 years of age. There were 203 boys and 100 girls and 79.3% of the patients were diagnosed as aseptic meningitis. Conclusions : We confirmed that enteroviral infections occurred in epidemics from late spring to fall during the study period. Enteroviral infections occurred predominantly in boys and the preschool children. Aseptic meningitis was the main illness in the hospitalized children.

Increased Matrix Metalloproteinase-9 and Tissue Inhibitor of Metalloproteinase-1 Levels in the Cerebrospinal Fluid from Children with Aseptic Meningitis (무균성 뇌수막염 소아에서 뇌척수액내 Matrix Metalloproteinase(MMP)-9과 Tissue Inhibitor of Metalloproteinase(TIMP)-1의 증가)

  • Purpose : Matrix metalloproteinase(MMP)-9 is known to breakdown the blood-brain barrier by degrading the extracellular matrix of the subendothelial basement membrane in meningitis. Tissue inhibitor of metalloproteinase(TIMP)-1, a known inhibitor of MMP-9, has been postulated to inhibit the proteolytic activity of MMP-9 by bindng to MMP-9, but their interaction has not been fully understood yet. So far, there have been some reports on the relationship of MMP-9 and TIMP-1 in bacterial meningitis, but few reports in viral meningitis. Furthermore, there has been no report on this in Korea. We investigated the concentrations of MMP-9 and TIMP-1 in cerebrospinal fluid (CSF) and serum of patients with viral meningitis and control subjects, and evaluated their relationship with other clinical parameters of meningitis. Methods : CSF and blood were obtained from 25 subjects with viral meningitis and 14 control subjects. After centrifugation, supernatants were stored at $-20^{\circ}C$ and we assayed concentrations of MMP-9 and TIMP-1 by the sandwich ELISA method. Results : Concentrations of CSF MMP-9 and TIMP-1 were significantly elevated in patients with viral meningitis, when compared with those in control subjects. Their serum levels showed no differences between the two groups. MMP-9 levels were closely correlated with TIMP-1 levels in the CSF($r_s=0.42$, P<0.05). CSF MMP-9/TIMP-1 ratios were significantly higher in patients with viral meningitis than those in the control subjects(P<0.05). Both CSF MMP-9 and TIMP-1 levels positively correlated with CSF total leukocyte counts($r_s=0.43$, P<0.05, $r_s=0.48$, P<0.05). TIMP-1 levels positively correlated with total protein concentrations in the CSF($r_s=0.43$, P<0.05). Conclusion : MMP-9 and TIMP-1 may play an important role in the breakdown and maintenance of BBB in viral meningitis, respectively.

  • The mumps virus is a single-stranded, non-segmented, negative-sense RNA virus belonging to the $Paramyxoviridae$ family. Mumps is characterized by bilateral or unilateral swelling of the parotid gland. Aseptic meningitis is a common complication, and orchitis is also common in adolescents and adult men. Diagnosis is based on clinical findings, but because of high vaccination coverage, clinical findings alone are not sufficient for diagnosis, and laboratory confirmation is needed. Mumps is preventable by vaccination, but despite high vaccination coverage, epidemics occur in several countries, including Korea. Many hypotheses are suggested for these phenomena. In this review, we investigate the reason for the epidemics, optimal methods of diagnosis, and surveillance of immunization status for the prevention of future epidemics.

  • Enterovirus commonly causes neurologic diseases (aseptic meningitis, encephalitis, etc.), hand-foot-mouth disease, herpangina, and acute hemorrhagic conjunctivitis. However, it rarely causes pneumonia in immunocompetent adults. In Korea, no case has been reported about pneumonia caused by enterovirus in healthy adults. We can cite the case of a 20-year-old woman who presented severe community-acquired pneumonia caused by enterovirus. The diagnosis was based on reverse transcriptase polymerase chain reaction (RT-PCR) of a respiratory specimen.
