The degenerative spondylolisthesis is one of the most common causes of the prominent central and recess stenosis which are produced by the hypertrophy of the facet joints and anterior slipping of the posterior arch. The resulting neurogenic symptoms in the legs are the major causes of the surgical treatment in the degenerative spondylolisthesis and the complete decompression is indicated for these types of spinal stenosis. The decompression procedures performed in the degenerative spondylolisthesis makes more unstable and induce the late instability and the post

PURPOSE: This study was performed to investigate the epidemiology of enterovirus (EV) infections in children at a secondary hospital during recent 5 years. METHODS: We collected the cerebrospinal fluid, stool and throat swab samples from the pediatric patients with suspected EV infections in KEPCO Medical Center, Seoul, Korea from July 2006 to September 2010. EV detection and genotype identification were performed by RT-PCR at Korea Centers for Disease Control and Prevention. RESULTS: A total of 386 samples were collected from 277 patients during study period. Ninety-eight patients (35.4%) were diagnosed with EV infections. The RT-PCR positive rate was the highest in throat swab samples (48.3%). The median age of patient was 4.7 years (range, 0.1-12.5 years). Aseptic meningitis (50, 51.0%) was the most common clinical manifestation; herpangina (22, 22.4%) and hand-foot-mouth disease (18, 18.4%). One hundred EVs were isolated from 98 patients and 20 genotypes of EV were identified; Echovirus 30 (28 cases, 28%), Enterovirus 71 (12 cases, 12%), Echovirus 25 (10 cases, 10%), Echovirus 9 (9 cases, 9%) and Coxsackievirus A6 (8 cases, 8%). Aseptic meningitis caused by Echovirus 30 was the most common manifestation in 2008. There was no complicated case caused by Enterovirus 71. CONCLUSION: This study showed the epidemiology of confirmed EV infection in children from 2006 to 2010. There is a need for continuous surveillance of EV infections and its clinical manifestations.

Neisseria animaloris is a common flora in animals, but its pathogenicity is rarely reported. In this case report, N. animaloris was isolated from a hospitalized cat with pneumonia. The cat was discharged after testing and treatment with appropriate antibiotics. This paper reports the first case of N. animaloris pneumonia in Korea.

The use of radiopharmaceuticals in evaluation of pulmonary tuberculosis may help to resolve difficult diagnostic problems such as discordance between sputum examinations and chest roentgenographic findings. We investigated the usefulness of 99mTc-methoxyisobutylisonitrile(MIBI) scintigraphy in the detection of active pulmonary tuberculosis. Forty-six patients with suspected active pulmonary tuberculosis were studied with sputum smear of AFB, sputum AFB culture, chest X-ray and MIBI scan. MIBI image was obtained 15 and 60 min after intravenous injection of 370MBq(10mCi) 99mTc-MIBI. In 16 patients of them Ga scans were performed in addition to MIBI scan. Repeated MIBI scans were done in 7 patients with active pulmonary tuberculosis after 4~6 months of antituberculous chemotherapy. Thirty-two patients were confirmed as active tuberculosis by sputum culture. Sensitivity of MIBI scan to active tuberculosis was 87.5%(28/32) and MIBI findings were negative in all of 14 patients with inactive disease. Focal uptake of MIBI was dense in the area that was strongly suggested active tuberculous lesions by chest roentgenogram. There was no discordance between MIBI and Ga image in 16 patients. But the uptake areas of Ga images were broader than that of MIBI images. After 4~6 months of antituberculous treatment all repeated MIBI scans revealed negative findings except 1 patient with persistent active pulmonary tuberculosis due to drug resistance. MIBI scan could be used in the detection of active pulmonary tuberculosis as a useful noninvasive diagnostic tool.

BACKGROUND: Combination of propofol and remifentanil is an ideal regimen for total intravenous anesthesia. The purpose of this study is to determine the effect-site concentration of remifentanil for prevention of hemodynamic responses to tracheal intubation during fixed propofol infusion (4microgram/ml) and to find any sexual differences. METHODS: Thirty ASA physical status I-II patients undergoing general anesthesia were assigned to male (n = 15), and female (n = 15) group. All patients received a target controlled infusion (TCI) of propofol with a fixed effect-site concentration of 4microgram/ml. After target effect-site concentration of propofol and remifentanil was reached, tracheal intubation was performed. The hemodynamic changes (systolic/diastolic blood pressure, mean arterial pressure, and heart rate) were measured at 1 and 2 min before tracheal intubation (baseline), immediately after, 1, 2, 3, 4 and 5 min following tracheal intubation. In both groups, effect-site concentration of remifentanil was initiated with 3 ng/ml. Subsequent concentration of remifentanil was determined by hemodynamic responses of the previous patient to tracheal intubation based on up and down sequential allocation. RESULTS: The mean EC50 of remifentanil for prevention of hemodynamic responses to tracheal intubation were 1.37 ng/ml (95% CI, 0.95-1.81 microgram/ml) in male group and 1.05 microgram/ml (95% CI, 0.68-1.40 ng/ml) in female group, respectively. In addition, there were no statistical significant differences between two groups. CONCLUSIONS: Relatively small dosages of remifentanil (0.68-1.81 microgram/ml) for attenuation of hemodynamic responses to tracheal intubation was needed in Korean population in propofol TCI and there were no sexual differences.

We have determined and analyzed the full-length cDNA sequence of a coxsackievirus B3 (CVB3) Korean isolate (CVB3-Korea/97) which has been known as a general human pathogen. The whole genome contains 7,400 nucleotides and has a single large open reading frame with 6,555 nucleotides that encodes a potential polyprotein precursor of 2,185 amino acids. The genome also contains a 5' non-coding region (NCR) of 741 bases and a 3' NCR of 104 bases followed by poly(A) tail. Sequence homologies of nucleotides and deduced amino acids between the CVB3-Korea/97 strain and the prototype (Nancy strain) were 81.7% and 91.5%, respectively. The genes encoding the functional proteins including viral protease and RNA dependent RNA polymerase showed higher homology than those encoding the structural proteins. We have further analyzed the sequences of 5' NCR, VP1 and VP2 of CVB3-Korea/97, which are known as cardiovirulent determining factors at the nucleotide and amino acid levels. Although the CVB 3-Korea/97 strain was isolated from an aseptic meningitis patient without cardiomyopathy, its 234th nucleotide and 165th amino acid were uracil and Asn as same as those of other cardiovirulent strains one. However, the 155th amino acid of VR1, which closely associated with cardiovirulence, was replaced with Arg155 by single nucleoptide substitution from A2916 to T2916. Moreover, additional amino acid substitutions were observed in the flanking region of Asp155. Taken together, aminoacid(s) substitution in VP1 may play a critical role in determining cardiovirulence of the CVB3-Korea/97 strain rather than individual nucleotide replacements in the 5' NCR and/or an amino acid substitution in VP2.

RUNX1, a member of the runt domain gene family of transcription factors, encodes a heterodimeric transcription factor and regulates the expression of various genes related to hematopoiesis and myeloid differentiation. RUNX1 has been one of the target genes for research into various autoimmune diseases due to its properties as a transcription factor and functional distribution for chromosomal translocation. In an effort to identify additional gene polymorphisms in which variants have been implicated in asthma, we investigated the genetic polymorphisms in RUNX1 to evaluate it as a potential candidate gene for a host genetic study of asthma and IgE production. We identified 19 sequence variants by direct DNA sequencing in 24 individuals of which four common variants were selected for genotyping in our asthma cohort (1,055 asthmatic patients, 384 normal controls). Using logistic regression analysis for association with the risk of asthma, while controlling for age, gender, and smoking status as covariates, no significant associations with the risk of asthma were detected. However, two polymorphisms in the promoter region (-2084G>C and -1282G>A) showed a marginal association with total IgE levels (0.03 and 0.03 in recessive models, respectively). Our findings suggest that polymorphisms in RUNX1 might be one of the genetic factors for the regulation of IgE production.

PURPOSE: Proteinuria is the hallmark of glomerular injury and results from alterations in glomerular permeability. The permeability of diseased glomerulus has been estimated by selectivity of proteinuria. Recently, some authors showed a significant relationship between selectivity of proteinuria and tubulointerstial damage. The present study examines the role of protein selectivity as a prognostic marker in patients with IgA nephropathy and its correlation with other prognostic indices. METHODS: The selective proteiuria index of 81 cases with IgA nephropathy diagnosed between 1990 and 2000 were reviewed, and each case was subclassified using the following : highly selective(SPI0.2). The mean age of the patients was 27+/-15 years with a follow-up period of 38+/-24 months. Six patients had highly selective proteinuria, thirty three patients had moderately selective proteinuria, and forty two patients had nonselective proteinuria. RESULTS: 1) A significant relationship was found between the SPI and Haas subclasess(p=0.01). With respect to clinical presentaion, hypertension(0, 4, 11 cases, p<0.05), proteinuria(0.52+/-0.35, 1.85+/-1.55, 2.79+/-2.51 g/day, p<0.05) were significant correlation.2) Chronic renal failure was significantly higher in patients with nonselective proteinuria in comparison with patients with selective proteinuria(p<0.05).3) Markers of renal failure by the Cox proportional hazards model were Cr(Exp(B)=4.2, p<0.001), Ccr (Exp(B)=2.1, p<0.05), SPI(Exp(B)=1.7, p<0.05), hypertension(Exp(B)=1.6, p<0.05). 4) In 28 patients of IgA nephropathy with nephrotic syndrome, 9 patients were moderately selective, 19 patients were nonselective. The response to therapy, evaluated retrospectively, was 67% and 16% in moderate and nonselective proteinuria(p=0.01). CONCLUSION: There is a significant relationship between selectivity of proteinuria and clinical para meters. Moreover, the selectivity of proteinuria has a predictive value on functional outcome.
