We have retrospectively analyzed the clinical and radiological outcome in 22 cervical spondylotic myeloradiculopathy patients who underwent combined front anterior decompression and fusion) and back (open door laminoplasty) surgery between Mar. 1991 and Jan. 1995. Clinical symptoms were evaluated by Japanese Orthopaedic Association(JOA) score and the recovery rate. Plain radiogram and MIR were taken before and after surgery, and then the cervical curvature, change of body to canal ratio and the A-P compression ratio of the cord were measured and compared to the clinical symptoms. Results : The mean JOA score increased from 10.1±3.3 preoperatively to 14.7±1.4 at the final follow-up with a mean recovery rate of 64.4%. No patients deteriorated as a result of the combined procedure. Post-op. radiograms showed an increasement of body to ratios (average 0.69±0.09 pre-op. to 1.0±0.13 post-op.) and maintenance or recovery of cervical Lordosis. On MRI, the A-P compression ratios of the cord were increased with recovery of subarachnoid space after the operation in most cases (average 38.4±7.6 pre-op. to 55.7±7.2 post-op.). Conclusion : This combined procedure safely and effectively resulted in decompression of the spinal cord and good functional recovery in patients with 1) anterior and posterior pathology, 2) narrow spinal canal and large spondylotic bar or herniated disc encroaching the spinal canal more than 5mm, 3) narrow spinal canal and kyphotic deformity, 4) narrow spinal canal and segmental instability, 5) multisegmental cord compression and severe radiculopathy.

BACKGROUND: Several studies have demonstrated that quantitation of hepatitis B virus (HBV) DNA in sera of HBsAg-positive patients is more useful test for the assessment of infectivity and for the evaluation of disease status than previously utilized numerous serological markers and qualitative polymerase chain reaction for the detection of HBV DNA. We tried to measure serum HBV DNA using a branched DNA (bDNA) signal amplification assay, which is recently introduced and known to be a simple and nonradioisotopic method. METHODS: Total forty patients with HBsAg were randomly selected and serum HBV DNA was measured with duplication using bDNA signal amplification assay (QUANTIPLEXTM HBV DNA ASSAY, Chiron, USA). Quantitation was determined from a standard curve and expressed as HBV DNA equivalents/mL (Eq/mL; 1 Eq = 1 molecule of the primary HBV DNA standard). Serum HBeAg, aspartate aminotransferase (AST), alanine aminotransferase (ALT) , and soluble interleukin-2 receptor (sIL-2R) were compared with HBV DNA. RESULTS: Serum HBV DNA was quantitated in 13 patients (32.5%) (range 6.4x106-7.4x109 Eq/mL, mean 1.8x109 Eq/mL, CV 8.1%). All eleven patients (100%) with both HBsAg and HBeAg an4 2 of 29 patients (6.9%) with HBsAg but not with HBeAg showed measurable HBV DNA (p < 0.001). In addition, serum levels of AST, ALT, and sIL-2R were significantly higher in HBV DNA measured patients compared with those of unmeasured patients. CONCLUSIONS: Above results show that more than half the HBsAg-positive patients do not have enough HBV DNA which is measurable with boNA signal amplification assay but all of HBeAg-positive patients and some of HBeAg-negative patients do. In addition, HBV DNA quantitation might be correlated with the disease activity in HBsAg-positive patients because serum levels of AST, ALT, and sIL-2R are higher in patients measured with HBV DNA than unmeasured.

PURPOSE: To evaluate the clinical characteristics, treatments and outcome of patients with hemorrhagic shock and encephalopathy(HSE) syndrome. METHODS: We performed a clinical study on 14 patients who were diagnosed as hemorrhagic shock and having encephalopathy syndrome in the Department of Pediatrics, from 1984 to 1998. Age, sex, clinical symptoms and physical findings at admission, the most deranged laboratory findings, radiologic findings, treatments and outcome were analyzed. RESULTS: The age of onset was 1.0+/-0.9 years and the male to female ratio was 1: 1.8. At admission, clinical findings included dehydration in 85.7%, shock in 85.7%, fever in 71.4%, vomiting in 71.4%, diarrhea in 64.3%, GI bleeding in 50%, convulsion in 42.9%, and edema in 35.7%. Altered mental state was found in 100%, hepatomegaly in 64.3%, and splenomegaly in 21.4%. Laboratory findings revealed D-dimer positive in 92.9%, the mean hemoglobin level 8.2+/-2.1g/dL, BUN 35.7+/-24.0mg/dL, creatinine 1.9+/-1.5mg/dL, AST 561.0+/-1,412.1IU/L, ALT 858.9+/-1,649.8IU/L, blood glucose 229.5+/-197.4mg/dL, ammonia 195.4+/-129.7pg/dL, and total bilirubin 4.9+/-8.2mg/dL. On serologic tests, rotavirus and Epstein-Barr virus was found in 1 patient(7.1%), respectively. The mortality rate was 78.6%. CONCLUSION: We found that shock and disseminated intravascular coagulation(DIC) played important roles in the pathogensis of HSE syndrome, and encephalopathy, hepatic and renal insufficiency, and respiratory failure were secondary complications resulting from shock and DIC. Despite vigorous treatment, the prognosis was very poor. We feel more efforts should be focused on investigating the etiology and pathophysiology of HSE to prevent as well as develop a specific therapy. (J Korean Pediatr Soc 2000;43:814-819)

BACKGROUND: T cell mediated immune destruction is an important mechanism of liver injury in patients with chronic hepatitis C. Serum levels of soluble interleukin-2 receptor(sIL-2R) seem to serve as a marker for the T cell activation and progressive liver injury, This study examined serum levels of sIft-2R and hepatitis C virus (HCV) RNA in patients with chronic HCV infection to determine the correlation with the severity of chronic hepatocellular damage. METHODS: Serum levels of sIft-2R in 73 patients with HCV infection (chronic hepatitis 52, liver cirrhosis 9, hepatocellular carcinoma 12) and 40 healthy controls were measured by sandwich enzyme immunoassay (CELLFREE, T Cell Sciences, USA). HCV RNA was quantified by QUANTIPLEX(TM) HCV RNA 2.0 assay (Chiron, USA) with duplication. This assay is a sandwich nucleic acid hybridization procedure using branched DNA amplification for the quantitation of HCV RNA. RESULTS: The sIL-2R levels of 52 patients with chronic hepatitis (591.4+/-238.7U/mL), 9 with liver cirrhosis(949.4+/-721.9 U/mL), and 12 with hepatocellular carcinoma (1,167.4+/- 554.4 U/mL) were significantly higher than those of healthy controls(370.8+/-71.8 U/mL) (p<0.001). A progressive and significant increase occurred in sIL-2R levels with chronic hepatitis C, liver cirrhosis and hepatocellular carcinoma (HCC) in order (p(0.001). The HCV RNA was detected in all patients and the means of HCV viral load were 3.3 MEq/mL in chronic hepatitis, 2.8 MEq/mL in cirrhosis, and 3.7 MEq/mL in HCC. There was no significant correlation between HCV RNA and the severity of liver injury in chronic HCV infection. There were no correlations among sIL-2R, HCV RNA and serum ALT. CONCLUSIONS: These results suggest that chronic hepatocellular injury by HCV progress mainly by T cell mediated immune response, not by direct cytopathic injury. Also, sIL-2R can be useful as a marker in monitoring the patients with HCV infection at high risk of getting HCC.

Synovial chondromatosis is an uncommon benign lesion characterized by multiple cartilagenous and osteocartilagenous nodules of the synovium and loose bodies. The affection is monoarticular and most commonly involves the knee and has an unknown etiology. Of the five cases of synovial chondromatosis experienced by the authors, both knee joints were involved in a case, two the elbow joint, and one the proximal phalanx of the left middle finger. The diagnosis of synovial chondromatosis was made by the histopathological findings of the excised masses.

Hemiplegic gait is characterized by slow and poorly coordinated movements of the affected limb resulting from foot drop or equinus deformities. Ankle-foot orthoses(AFO) are frequently prescribed to improve the gait pattern of hemiplegics. Plastic AFO with different trimlines in controlling ankle motion can cause variable biomechanical effects. In this study, we analysed the biomechanical effect of donning AFO on hemiplegic gait and assessed whether any differences resulted when the AFO was modified. Gait events, plantar pressure, foot contact and centers of pressure(COP) parameters were measured with F-scan pressure sensitive insole system in 21 hemiplegic stroke patients with Brunnstrom's lower extremity stage 3. And those parameters were compaired in each of four different conditions: 1) before donning AFO, 2) donning AFO without any modification, 3) donning AFO with the dis tal part of metatarsal head trimmed off, 4) donning AFO with third condition and weaning a cushioned heel shoes. After donning AFO, total contact area and contact width were increased, and initial contact COP and mean COP were displaced medially. But contact length was not changed and initial contact COP and mean COP were not displaced anteroposteriorly. Anteroposterior displacement of COP, slope and velocity of COP were not also changed after donning AFO. Among various AFO adjustments, there were no significant changes of plantar pressure, foot contact and COP parameters. The results suggest that 1) AFO provides mediolateral stability, but does not provide additional functional rocker actions during stance phase and 2) There were no definite different biomechanical actions among various adjustments of plastic AFO in hemiplegic gait of Brunnstrom's lower extremity stage 3.
