1.Ventriculoperitoneal shunt-related infections caused by Staphylococcus epidermidis
Chinese Journal of Clinical Infectious Diseases 2015;(4):371-375
Staphylococcus epidermidis has the ability to adhere to the surface of shunt tube and to develop the biofilm .It can embed itself in the biofilm so as to escape from the defense of the host .Due to the presence of biofilms , antimicrobial drug resistance , blood brain barrier of central nervous system , the treatment of shunt-related infection caused by Staphylococcus epidermidis is very difficult.This paper reviews the risk factors , prevalence , pathogenesis , treatment and prevention of ventriculoperitoneal shunt-related infections caused by Staphylococcus epidermidis.

Objective To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods From February1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio , 1.068; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.
