  • Objective : Many surgeons advocate for watertight dural reconstruction after posterior fossa surgery given the significant risk of cerebrospinal fluid (CSF) leak. Little evidence exists for posterior fossa dural reconstruction utilizing monolayer collagen matrix onlay graft in a non-watertight fashion. Our objective was to report the results of using collagen matrix in a non-watertight fashion for posterior fossa dural reconstruction. Methods : We conducted a retrospective review of operations performed by the senior author from 2004-2011 identified collagen matrix (DuraGen) use in 84 posterior fossa operations. Wound complications such as CSF leak, infection, pseudomeningocele, and aseptic meningitis were noted. Fisher's exact test was performed to assess risk factor association with specific complications. Results : Incisional CSF leak rate was 8.3% and non-incisional CSF leak rate was 3.6%. Incidence of aseptic meningitis was 7.1% and all cases resolved with steroids alone. Incidence of palpable and symptomatic pseudomeningocele in follow-up was 10.7% and 3.6% respectively. Postoperative infection rate was 4.8%. Previous surgery was associated with pseudomeningocele development (p<0.05). Conclusion : When primary dural closure after posterior fossa surgery is undesirable or not feasible, non-watertight dural reconstruction with collagen matrix resulted in incisional CSF leak in 8.3%. Incidence of pseudomeningocele, aseptic meningitis, and wound infection were within acceptable range. Data from this study may be used to compare alternative methods of dural reconstruction in posterior fossa surgery.

  • Purpose : Aseptic meningitis is relatively frequent in children and caused mostly by enterovirus. The aim of the present study was to determine the effect of early diagnosis (spinal tapping) on symptom duration of childhood aseptic meningitis. Methods : One hundred fifty-three children who were hospitalized due to aseptic menigitis in the Department of Pediatrics St. Benedict Hospital from July 1996 through October 1996 were included in this study. Patients were divided to two groups according to the duration from first symptom onset to diagnosis. Early diagnosis group is diagnosed within 3 days from first symptom onset. Later diagnosis group is diagnosed after 4 days from first symptom onset. Results : 1) The average age of these patients was 4.3 years old in early diagnosis group and 4.1 years old in later diagnosis group. The sex ratio(male: female) was 2.04:1 in early diagnosis group and 2.5:1 in later diagnosis group. 2) The mean duration of diagnosis of this study was 2.04 day in early diagnosis group and 5.12 day in later diagnosis group. 3) The percentage of symptom and sign of the early diagnosis group were fever(100%), headache(88.4%), vomiting(86.9%), abdominal pain(39%), neck stiffness(36.2%), skin rash(18.8%), diarrhea(16.9%) and that of later diagosis group were fever(100%), headache(83.3), vomiting(80.9%), abdominal pain(47.6%), neck stiffness(41.6%), skin rash(29.7%), diarrhea(16.6%). 4) Initial CSF findings revealed leukocyte $146.8{\pm}386.3/mm^3$ with PMNL 38%, protein 32.47mg/dl, sugar 66.23mg/dl in early diagnosis group and leukocyte $458.1{\pm}663.2/mm^3$, protein 31.22mg/dl, sugar 64.21 mg/dl in later diagnosis group. 5) There was no statistically significant differance in the peripheral blood findings between early diagnosis group and later diagnosis group. 6) The duration of disappearance of symptom after spinal tap were 2.3 days in early diagnosis group and 2.24 days in later diagnosis group. Total symptom duration was 4.34 days in early diagnosis group and 7.36 days in later diagnosis group. Conclusions : Our results demonstrate that early diagnosis(early spinal tap) shortened duration of clinical symptoms.

  • Purpose : There was a outbreak of aseptic meningitis in Busan, 2002. We report the clinical features and causative viruses. Methods : Two hundred seventy six children with aseptic meningitis who were admitted to the Department of Pediatrics, Maryknoll Hospital between January and December, 2002 were included. CSF, stool and throat swab viral cultures were done in 244 of these children. Results : The male to female ratio was 1.4 : 1. Age of patients varied from five months to fourteen years old. Average age was $5.7{\pm}6.2years$ old and mostly between one and four years.(41.3%) Monthly distribution revealed that the number of patients increased from May to July. The main symptoms were fever, headache and vomiting in this order. Respiratory tract infection symptom was associated from June to July and headache and nausea without fever were characteristically observed in children more than 10 years old from November to December. In peripheral blood examination, leukocytosis(WBC>$10,000/mm^3$) showed in 34.8%, ESR was increased in 56.1%, and CRP was positive value in 61%. Therefore differential diagnosis was difficult through peripheral blood examination. CSF findings revealed mean leukocyte count $86.5{\pm}180.2/mm^3$, protein $41.7{\pm}32.9mg/dL$, glucose $56.4{\pm}9.9mg/dL$. Median hospitalized period was $4.7{\pm}7.2days$ and compared with non-tapping group, hospitalized period was shorter and subsidance of symptoms was faster, therefore antibiotics injection period was shorter in the spinal tapping group. Virus was isolated in 31 cases of 244. The causative agents were echovirus 6, echovirus 9, echovirus 25, coxsakie virus B3, B4. Conclusion : There was an epidemics of aseptic meningitis in Busan, 2002; the causative agent was echovirus 6, 9, 25, coxsakie virus B3, B4.

  • Varicella-zoster virus is a human herpesvirus that causes chickenpox (varicella), becomes latent in cranial nerve and dorsal root ganglia, and frequently reactivates to produce shingles (zoster) and postherpetic neuralgia. Varicella zoster meningitis is a rare complication after varicella zoster infection. It usually affects a patient of immunocompromised or impaired cellular immunity, is rare in a immunocompetent child. We report two cases of aseptic meningitis in association with varicella zoster, not having any complication in the immunocompetent children.

  • Purpose : Meningitis is an inflammation of meninges by various kinds of organisms. Almost 85% of aseptic meningitis is caused by Enterovirus. This study was done to detect the causative virus of those with aseptic meningitis through sequencing the 5'-noncoding region to compare prototype and homology. Methods : RNA was extracted from Coxsackie Bl, Echovirus 3, 7, 9, 30. DNA was synthesized by RT-PCR and we compared homology with prototype from WHO by direct sequencing. Results : 1) PCR products from these viruses showed same bands of 155 bp and 440 bp on gel electrophoresis. 2) Coxsackievirus and Echovirus 11 prototype sequences were compared, which showed 12 bp changes with 92.1%. 3) Coxsackievirus B1 from a patient showed 94.1% homology when compared with prototype. 4) Echovirus 3 showed 92.8%, echovirus 7 92.8%, echovirus 30 82.9% homology. Conclusion : 5'-NCR of enterovirus has high homology which was good for use of diagnosis and more long sequencing requires for typing of viruses.

  • Enteroviruses isolation were attempted from samples obtained from aseptic meningitis-suspected patients in hospitals in Busan during 2000-2002. Enteroviruses were found in 2 of 292 cases in 2000, 4 of 371 cases in 2001, 83 of 703 cases in 2002. In 2000, the isolated viruses were found to be echovirus serotype 11 and coxsackievirus serotype B2. Coxsackievirus serotype B5 was isolated in 2001 and in 2002, echovirus serotypes 2, 3, 6, 7, 9, 13, 25, 30 were isolated in 70 cases while coxsackievirus serotypes B3 and B4 were isolated in 10 cases. Various specimens tended to emerge over the years. The occurrence in 2000 tended to be mostly focus during the cold months, December through January, while in 2001, it occurred in May. In 2002, occurrence was found to be distributed from April to November with the highest rate during June and July. The strains of Vero and HEp-2 of echovirus and coxsackievirus, respectively, are highly infectious. Electron micrograph of echovirus and coxsackievirus show that they are small nonenevolped, isometric-shaped viruses. Isolated RNA from strains of echovirus and coxsackievirus showing cytopathic effects were used to undergo nested PCR which resulted in a 436 bp single band in all the strains. The serotype was sent to the Department of Virology at the Korean National Institute of Health for identification.

  • Epidural steroid injection(ESI) has been a commonly applied conservative therapy for the management of chronic low back pain and sciatica. However, there are many reports concerning various local, systemic and neurological complications related to ESI. We report two cases with fatal complications after ESI for low back pain and sciatica. In both patients, ventriculitis and meningitis were causative factors to be fatal. Aseptic procedures and careful post-procedure assessment are essential to avoid serious complications following ESI.

  • Purpose : Enteroviruses are the most common cause of aseptic meningitis in patients of all ages. A definite diagnosis of enteroviral meningitis can be established by detection of virus directly in CSF specimens. But this is time-consuming and lacks sensitivity, so polymerase chain reaction(PCR) detecting of viral RNA in patient specimens such as CSF, stool has been demonstrated. But little is known about the influence of sampling time on the results of CSF PCR and stool PCR. We investigated diagnostic utility of PCR of CSF and stool according to sampling time after the onset of symptoms. Methods : PCR results were analyzed according to sampling time for 42 patients diagnosed aseptic meningits in our hospital from $11^{th}$ January to $30^{th}$ August, 2005. Results : The diagnostic yield of the test was higher of CSF specimens obtained ${\leq_-}2$ days after clinical onset(positive PCR results 9/18, 50 percent), compared with CSF collected >2 days after onset(positive PCR results 1/24, 4.2 percent)(P=0.001). Instead, positive PCR results of fecal specimens maintained highly(average 90.5 percent), 10 cases had also positive PCR results even 5-6 days after onset. 10 cases of CSF specimens had positive enterovirus PCR results containing coxsackievirus B5 (n=6), coxsackievirus B3(n=3). 38 cases of stool specimens had positive enterovirus PCR results containing echovirus 18(n=7), echovirus 9(n=3), coxsackievirus B5(n=8), coxsackievirus B3(n=3). 6 cases(coxackie B5) had positive CSF PCR and stool PCR, both. Conclusion : Stool PCR was clinically sensitive for detecting enterovirus during enteroviral meningits and could give a presumptive diagnosis throughout the disease course. A definite diagnosis was obtained by CSF PCR, but its utility was clearly lower for samples obtained >2 days after clinical onset. Therefore, it is recommended that, in addition to performance of CSF PCR, fecal samples obtained from patients with suspected enteroviral meningitis should be tested by PCR, especially when the duration of symptoms is >2 days.

  • Background: There have been an increasing number of reports about infection-related complications after epidural block, and the analysis of these previous reports may offer valuable information for the prevention and treatment of such complications. Methods: We searched for complications about infection that was related to epidural blockade procedures by using the Medline Search program. We analyzed the types of infection-related complications as well as the potential risk factors, the time course from symptom development to treatment, the causative organisms and the treatment outcomes. Results: Seventeen cases were identified. The types of complications were epidural abscess, subdural abscess, spinal arachnoiditis, bacterial meningitis and aseptic meningitis. Five patients received a single block and twelve patients received a continuous block with catheterization. The most common site of epidural catheterization was the lumbar area and eight patients had indwelling catheters for less than fifteen days. Eight patients had a diabetes mellitus as a risk factor and fourteen patients showed less than seven days from the development of symptoms to treatment. Eleven patients received laminectomy and intravenous antibiotics as a treatment and eight patients had full recovery without neurological deficit. Conclusions: Early diagnosis and treatment is essential for the favorable outcome of infection-related complication after epidural block. In addition, absolute sterile technique should always be performed and patient education concerning these potential complications must be accompanied.

  • Ramsay Hunt syndrome (RHS) is a disease caused by varicella-zoster virus (VZV) infection that can be diagnosed through clinical symptoms with or without imaging evaluations. The typical features of RHS on imaging evaluation include signal changes and enhancement in the internal auditory canal (IAC) nerves, and the labyrinthine segment of cranial nerve VII (CN VII) and cranial nerve VIII (CN VIII). In some patients, inner ear structure (cochlear and vestibular apparatus) is involved in RHS. Neurologic complications, such as encephalitis and meningitis, are rare in RHS, but are known to occur. Therefore, magnetic resonance imaging (MRI) is necessary to detect both abnormal signal intensity in the IAC, CN VII, CN VIII, inner and ear structure, and CNS complications. We report an RHS patient with CN VII, VIII, and leptomeningeal enhancement within the cerebellar folia on 10-min delayed, contrast-enhanced (CE), three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) imaging.
