ABSTRACT
Objective To compare the curative effect of conservative treatment and full thread hollow screw in the treatment of Ekrol 2 fracture of the fifth metatarsal bone.Methods From April 2013 to May 2015,42 patients with avulsion fractures of the fifth metatarsal basement of type 2 fractures in Ekrol division were treated in our hospital.23 patients underwent full thread hollow screw surgery (surgical treatment group),and there were 12 males and 11 females,with an average age of 43.4±9.2 years,and the fracture displacement length was 2.3±0.2 mm.19 patients treated with plaster fixation (conservative group),including 10 males and 9 females,with an average age of 45.7±8.9 years and fracture displacement length was 2.1±0.2 mm.During follow-up,X -ray examination was performed to evaluate the time of fracture healing and forefoot score of American Orthopaedic Foot and Ankle Society (AOFAS),visual analogue score (VAS) and quality of life questionnaire (SF-36) were compared between the two groups.Results All 42 patients were followed up for 12 to 24 months with an average of 18 months.At the latest follow-up,the fracture healing time of the surgical group was 9.3±2.0 weeks,with AOFAS score of 84.1±3.9,VAS score of 0.1±0.2,and the SF-36 score of 95.1±2.9 points,and the shortening of length after treatment was 2.1±2.5 mm;the average healing time of the conservative treatment group was 12.2±2.1 weeks,with the average AOFAS score of 84.2±4.2 points,and the average VAS score of 0.2±0.2 points,the average SF-36 score of 94.1 ±5.2 points,and the shortening of length after treatment was 0.4±2.5 mm.The results of each short-term score and the shortening of the length of the fracture after treatment was statistically significant.The results of the mid-and long-term scores showed no significant difference between the two groups;the fractures of both groups reached bone healing.3 cases of sural nerve stimulation occurred in the operation group,while 1 case occurred in the conservative group.Abnormal healing occurred in 2 cases of conservative treatment,and the fractures of the surgical treatment group were anatomic reduced.Conclusion Usingfull thread hollow screwfor the treatment of Ekrol 2 fracture of the fifth metatarsal bone is better than the conservative treatment in the short term,but there is no significant difference in the long-term effect.
ABSTRACT
Objective To investigate the diagnostic value of plasma B-type natriuretic peptide(BNP) in left to right shunt congenital heart disease accompanied by heart failure in PICU.Methods We retrospectively reviewed the clinical data of 52 cases diagnosed left to right shunt congenital heart disease in the PICU of Shengjing Hospital of China Medical University from January 2012 to June 2014.The cases were divided into negative control group(n=18) and heart failure group(n=34) according to the criteria for the diagnosis of pediatric heart failure.We respectively compared plasma BNP,size of heart defects,left ventricular end-diastolic volume index(LVEDVI),ratio of left ventricular early diastolic filling blood flow velocity and left ventricular late diastolic filling blood flow velocity(E/A),left ventricular ejection fraction(LVEF),pulmonary artery systolic pressure(PASP),and cardiothoracic ratio between the two groups.We analyzed the correlation between plasma BNP and the size of heart defects,LVEDVI,E/A,cardiothoracic ratio,LVEF,PASP.The receiver operating characteristic curve was used to determine the optimal cut-off value of plasma BNP to diagnose heart failure.Results Plasma BNP were 87.7(22.7,165.7)pg/ml in negative control group and 716.5(326.8,1813.0)pg/ml in heart failure group.The plasma BNP level of heart failure group was significantly higher than that of negative control group(Z=5.3,P<0.01).Size of heart defects were 5.0(3.0,6.8) mm in negative control group and 7.4(5.5,9.0)mm in heart failure group.Size of heart defects of heart failure group was significantly higher than that of negative control group(Z=3.5,P<0.01).LVEDVI were (44.6±18.3)ml/m3 in negative control group and (70.8±38.4)ml/m3 in heart failure group.LVEDVI of heart failure group was significantly higher than that of negative control group(t=2.7,P=0.01).E/A were 1.3±0.3 in negative control group and 1.1±0.3 in heart failure group.E/A of negative control group was significantly higher than that of heart failure group(t=2.2,P=0.04).Plasma BNP had a positive relation with cardiothoracic ratio(r=0.49,P=0.01) and a negative correlation with E/A(r=-0.28,P=0.04).The optimal cut-off value of plasma BNP was 181.8 pg/ml.The sensitivity of diagnosis of heart failure was 94% and the specificity was 88%.The area under the receiver operating characteristic curve was 0.951.Conclusion Plasma BNP may comprise a sensitive marker for heart failure of left to right shunt congenital heart disease.It is recommended that 181.8 pg/ml is the optimal cut-off value to diagnose heart failure of left to right shunt congenital heart disease.
ABSTRACT
Transcranial Doppler ultrasonography(TCD)can be usd to monitor the cerebral blood flow changes noninvasively in real time. It provides important information for cerebrovascular hemodynamics in children with nervous system diseases,especially for the critically ill children.TCD is widely used in diagnosis and therapy of traumatic brain injury,increased intracranial pressure,cerebral vasospasm,stroke,cerebral vascular dysfunction,central nervous system infection,brain death.TCD can reveal the cerebral perfusion and the response to the treatment and help to guide the treatment.Besides,through the analysis of the change of the cerebrovascular hemodynamics,we can find the underlying pathophysiology mechanism of the diseases. In this paper,the application of TCD was reviewed to spread the use of TCD in monitoring and treantment of children in PICU.
