ABSTRACT
Objective To investigate the characteristics and clinical significance of increased procal-citonin( PCT) in infant muggy syndrome( IMS) .Methods A total of 23 IMS cases admitted in PICU from Nov 2011 to Apr 2012 were enrolled.All cases were devided into three groups according to pediatric critical illness score,high risk group(n=5),medium risk group(n=12),and mild risk group(n=6).And 23 cases were also divided into infection group and no infection group according to baseline disease before onset.The relationship of PCT and pediatric critical illness score,primary infectino and infection index weer observed, and the possible causes of icn reased PCT in IMS were explored.Twenty age mathc ed infants reec iving exami-nation in clinic served as control gor up.Re sults PCT inrc eased significantly in IMS cases.The PCT level was(91.5 ±90.9) ngm/l ni high risk group,(81.1 ±74.1) ng/ml in medium risk group,and(112.1 ± 74.9) ng/ml in mild risk group,there were no significant differences among trh ee groups( F=0.371,P =0.732).Other infection index like leukocyte conmt,neutrophil and C reactvi e prto ein in IMSg roup were higher thant hose int he cno trol group,and the results had significant differences( P<0.05,reps ectively) .The PCT level was(72.5 ±74.4) ng/ml in infce toi n group,(101.5 ±76.6) ng/ml in no infection rg oup,and there was on sing ificant difference between two groups(t=0.873,P=0.392).There was no relevance be-tween increase of PCT and the incidence of infection before IMS.But PCT had higher correlation to the body tem-perature after IMS(r=-0.362,P=0.049).Conclusion There is correlation between the increased PCT and fever in IMS,and fever in IMS would lead to inflammation and then resulted in the increase of PCT.
ABSTRACT
Objective To investigate MRI findings and its relationship with clinical grading and prognosis of infant muggy syn-drome (IMS).Methods Twenty five cases of IMS diagnosed newly and nine cases of IMS with follow-up were collected.MRI find-ings were retrospectively analyzed and compared with their clinical data.Results Seven early abnormal signs could be shown on cer-ebral MRI examination.There was no correlation between the clinical grading and three abnormal signs,which were subdural effu-sion,supratentorial cerebral edema and subarachnoid hemorrhage (P >0.05).In contrast,the other four abnormal signs (abnormal signal of subcortex and cortex,diffuse cerebral hemorrhage,basal ganglia and corpus callosum edema or infarction,large area cere-bral infarction)were closely related to the severity of clinical symptom (P <0.05).MRI findings had certain correlation with clinical classification.Conclusion MRI can objectively reflect the serious change of brain damage in IMS,and provide important information for clinical therapy and prognosis.
