Clinical features and risk factors of pertussis in children / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features and risk factors of pertussis in children.@*METHODS@#A retrospective analysis was performed for the clinical data and laboratory markers for immune function of 253 hospitalized children with pertussis. A total of 314 hospitalized children with cough were used as the control group. Quantitative real-time PCR was used to detect Bordetella pertussis DNA. The clinical data of both groups were collected to analyze the risk factors for pertussis.@*RESULTS@#A total of 23 typical clinical parameters were compared between the pertussis and control groups, and there were significant differences in only 10 clinical parameters between the two groups (P<0.01). As for the complications observed in the two groups, the pertussis group had a significantly lower incidence rate of myocarditis than the control group (P<0.05). The pertussis group had significantly lower levels of serum globulin and IgM than the control group (P<0.05). Compared with the control group, the pertussis group had a significantly higher proportion of children with a lack of diphtheria-pertussis-tetanus immunization or timely immunization and a contact history of suspected pertussis patients (P<0.05). A lack of vaccine immunization or timely immunization and a contact history of suspected pertussis patients were risk factors for pertussis (P<0.05).@*CONCLUSIONS@#The clinical features are not typical in children with pertussis. Quantitative real-time PCR for detecting Bordetella pertussis DNA helps with the early diagnosis of atypical pertussis. Infants/toddlers should be immunized in time and be isolated from suspected pertussis patients to reduce the incidence of pertussis.

Diagnostic value of serum and bile survivin levels in obstructive jaundice / 中国现代普通外科进展

Objective:To detect the bile and serum survivin levels in patients with obstructive and to determine whether bile and/or serum survivin be helpful in distinguishing malignant obstructive jaundice (cholangiocarcinoma) from benign obstructive jaundice.Methods:Bile and serum survivin levels were determined using enzyme-linked immunosorbent assay.Receiver operating characteristic (ROC) curve was used to evaluate the feasibility of bile and/or serum in differentiating malignant obstructive jaundice from benign obstructive jaundice.Results:Mean bile survivin concentrations were significantly higher in cholangiocarcinoma compared to choledocholithiasis,benign biliary stricture,compressive stenosis and normal controls(P＜ 0.05,respectively).However,only mean serum survivin concentrations were significantly higher in cholangiocarcinoma than normal controls(P=0.009).For bile survivin,the area under the curve (AUC) was 0.780(P ＜ 0.001),and the optimal cut-off value determined was 772.28 pg/mL,providing a sensitivity of 67.27 ％ and a specificity of 80.85 ％.But the AUC was only 0.600 for serum survivin (P=0.084).Conclusions:These findings reveal that bile survivin is significantly increased in patients with cholangiocarcinoma,and bile survivin may be a useful indicator in differentiating distinguishing cholangiocarcinoma from benign obstructive jaundice.
