目的　研究小儿头部CT呈肉芽肿样改变的常见病因。方法　通过临床症状、体征、结合头部CT、血常规、结核菌素试验、X线胸片、脑脊液常规生化检查及血和脑脊液间接凝集试验等检查 ,并结合试验治疗确定病因。结果　 2 8例患儿中符合脑囊虫 15例 ,脑脓肿 8例 ,脑结核瘤 5例。结论　凡小儿头部CT显示肉芽肿样改变者应首先鉴别是否患脑囊虫、脑脓肿、脑结核瘤

The rapid and early diagnosis of respiratory infection with mycoplasma pneumoniae in children

Objective To study the rapid diagnosis and accuracy of MCMDI usedin respiratory infection with mycoplasma pneumoniae. Methods Collect terminal blood of patients 20μL on the glass, under multimedia computing microscopy diagnostic instrument, observe the shape and movement of mycoplasma pneumoniae adhered the surface of RBC. At the same time, measure Mp - IgM and CAT in serum. Results The positive rate of MP in terminal blood was 80.6% ,Mp- IgM was 62.0%. CAT was 55.5%. The positive rate of MP in terminal blood was positively correlated with the positive rate of MP - IgM in serum( P ＜ 0.005 ), and had no correlation with the course of disease. Conclusions MCMDI can be applied to the rapid and early diagnosis of respiratory infection with mycoplasma pneumoniae.
