Electrocorticography-guided surgical treatment of solitary supratentorial cavernous malformations with secondary epilepsy / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To evaluate the efficacy of electrocorticographic (ECoG) monitoring and the application of different surgical approaches in the surgical treatment of solitary supretentorial cavernous malformations with secondary epilepsy.</p><p><b>METHODS</b>This study enrolled a consecutive series of 36 patients with solitary supratentorial cavernous malformations and secondary epilepsy who underwent surgery with intraoperative ECoG monitoring in the Department of Neurosurgery between January 2004 and January 2008. The patients were composed of 15 males and 21 females, aged between 8 and 52 years (mean age 27.3±2.8 years) at the time of surgery. Epilepsy history, the type of epilepsy at the presentation, lesion location, the incidence of residual epileptiform discharges, and postoperative outcomes were evaluated.</p><p><b>RESULTS</b>Histopathological examination indicated cavernous malformations and hippocampal sclerosis in 36 and 5 cases, respectively. Neuronal degeneration, glial cell proliferation, and neurofibrillary tangles were found in all the resected cerebral tissues of extended lesionectomy of residual epileptic foci. Lesionectomy, anterior temporal lobectomy, anterior temporal lobectomy plus cortical thermocoagulation, extended lesionectomy, extended lesionectomy plus cortical thermocoagulation were performed in 4, 4, 1, 14, and 13 cases, respectively. Residual epileptiform discharges were captured in 9 out of the 14 patients who had additional cortical thermocoagulation. According to Engle class for postoperative outcomes, 27 cases were class I (75.00%), 5 were class II (13.89%), 2 were class III (5.56%), and 2 were class IV (5.56%), thus the total effective rate (class I+class II) was 88.89%. Neither of epilepsy history, the type of epilepsy, and the location of cavernous malformation was significantly related to outcomes (P>0.05). A significant relationship was found between the incidence of residual epileptiform discharges and outcomes (P=0.041).</p><p><b>CONCLUSIONS</b>Intraoperative ECoG monitoring, the application of different surgical approaches, and the resection of residual epileptic foci could produce good result in the surgical treatment of supratentorial cavernous malformation with secondary epilepsy. Postoperative residual epileptiform discharges could be a useful predictor for evaluating the outcomes.</p>

Clinical analysis of hemolytic-uremic syndrome associated with Streptococcus pneumoniae serotype 3 infection in a child / 中华儿科杂志

<p><b>OBJECTIVE</b>To study the clinical characteristics of Streptococcus pneumonia-associated hemolytic uremic syndrome (SP-HUS) in children.</p><p><b>METHOD</b>Clinical and laboratory data of a pediatric case of SP-HUS were retrospectively analyzed and the key points of diagnosis and therapy were reviewed.</p><p><b>RESULT</b>An 18-month old girl was admitted with chief complaint of fever and cough for 5 days combined with mild labored breath. Breath sound was found weakened in right lung with lower lobe dullness on percussion. Laboratory tests revealed: WBC 3.7×10(9)/L, Hb 83 g/L, PLT 11×10(9)/L, C-reactive protein (CRP) > 180 mg/L. Morphological study of the RBCs showed marked anisocytosis and schistocytosis. Urinalysis showed 42.66 RBCs per high-power field, occult blood (+++), proteinura (++++). Streptococcus pneumoniae was isolated from blood, pleural fluid and sputum. Serotyping with simplified chessboard system was 3. The direct Coombs test was positive. Serum complement levels (C3 and C4) were depressed at 0.699 g/L, 0.064 g/L, respectively. Chest X-ray showed pleural effusion and infection of the right hemothorax. The computerized tomographic scan of the chest revealed pneumatoceles in the right lower lobe. The diagnosis on admission we considered was SP-HUS. Intravenous antibiotic therapy (vancomycin + cefoperazone/sulbactam) was administered. The renal replacement theraphy was administered to maintain electrolyte and fluid balances and adequate nutrition. Transfusions of washed red blood cells were administered to correct the anemia. One month after admission the patient was good with recovery. Liver and renal function recovered and the pneumonia was resolving, anemia and platelets were corrected. The direct Coombs test turned to be negative. Serum complement levels (C3 and C4) were normal. After 3-month follow-up, no clinical anomalies were detected.</p><p><b>CONCLUSION</b>SP-HUS should be suspected when the following occurs in the context of pneumococcal infections: microangiopathic hemolytic anemia, thrombocytopenia, acute renal failure and a positive Coombs test result. Serotype 3 of SP was associated with HUS.</p>

Contents of serum albumin after surgical operation in children with acute intussusception / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the changes of serum albumin contents after operation and investigate whether post-operational serum albumin contents are correlated with the disease severity in children with acute intussusception.</p><p><b>METHODS</b>Serum albumin contents were measured using the automatic biochemistry analyzer in 32 children with mild acute intussusception and 21 children with severe acute intussusception 1 day after surgical operation. After 5 days combined treatment, serum albumin contents were re-examined. Thirty healthy children severed as the control group. The correlation between post-operational serum albumin contents and critical illness scores was evaluated.</p><p><b>RESULTS</b>Serum albumin contents in the mild (34.2+/-6.5 g/L; P<0.05) and the severe intussusception groups (25.8+/-7.5 g/L; P<0.01) 1 day after operation were significantly lower than those in the control group (37.1+/-4.1 g/L). There were significant differences in serum albumin contents between the mild and the severe intussusception groups (P<0.05). Five days after operation, serum albumin contents in the mild intussusception group significantly increased (37.1+/-11.4 g/L; P<0.05), while serum albumin contents in the severe intussusception group did not differ from those 1 day after operation. There was a positive correlation between serum albumin contents on the 1st day after operation and the critical illness scores (r=0.879, P<0.01).</p><p><b>CONCLUSIONS</b>Serum albumin contents decreased on the 1st day after operation and were correlated with the disease severity in children with acute intussusception. Hypoalbuminemia lasted for a longer period in severe cases. The post-operational measurement of serum albumin contents may be useful in the evaluation of the severity for children with acute intussusception.</p>
