ABSTRACT

Objective:To investigate the clinical characteristics, diagnosis and treatment of mycoplasma pneumoniae(MP) pneumonia in children with pseudo-macrocytic erythrocytes.Methods:The clinical data of 50 children with mycoplasma pneumoniae pneumonia with pseudo-macrocytic erythrocytes in the Department of Pediatrics at Shengjing Hospital of China Medical University from January 2019 to August 2020 were analyzed retrospectively.Results:Among the 50 cases, there were 32 boys and 18 girls.The blood routine examination showed that pseudo-macrocytic erythrocytes, red blood cells decreased significantly, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration increased significantly, as well as MP-IgM was positive.Sixteen cases were complicated with herpes simplex virus infection, one with Epstein Barr virus infection, and six with both herpes simplex virus and Epstein Barr virus infection at the same time.All 50 cases were MP pneumonia, pulmonary imaging showed lobar pneumonia, and 25 cases were complicated with pleural effusion, including 32 cases of refractory MP pneumonia.The clinical symptoms of three cases were extrapulmonary manifestations, hemolytic anemia and diagnosed with cold agglutinin syndrome.In 36 children with D-dimer more than 252 μg/L, one case had femoral vein thrombosis and one case had pulmonary embolism.Conclusion:Pseudo-macrocytic phenomenon may play important roles in clinical etiological diagnosis, severity of disease and refractory MP pneumonia.The children with hemolytic anemia suggest cold agglutinin syndrome, and the hypercoagulable state of MP infection may be related to the aggregation of red blood cells caused by cold agglutinin in MP infection.

ABSTRACT

Objective:To explore the clinical characteristics and early diagnosis of cerebral infarction in critically ill children.Methods:The clinical data of the children who were diagnosed with cerebral infarction in PICU at Shengjing Hospital of China Medical University from January 2013 to September 2019 were analyzed retrospectively.Results:There were 27 children in this study, including 15 males and 12 females.The age of onset ranged from 1 month to 13 years old, with age of 3.0(0.7, 8.0) years old.Among 27 cases, there were ten cases of infection(37.0%), six cases of trauma(22.2%), three cases of congenital heart disease (11.1%), two cases of cerebrovascular disease (7.4%), one case of diabetic ketoacidosis(3.7%) and two cases of autoimmune factors(7.4%). The cause was unknown in three cases(11.1%). The main clinical manifestations were convulsion in 11 cases(40.7%), status convulsion in five cases(18.6%), limb dysfunction in four cases(14.8%), disturbance of consciousness in fvie cases(18.5%) and facial paralysis in four cases(14.8%). Among 27 cases, mechanical ventilation was performed in 12 cases (44.4%). The levels of D-dimer in all children were increased in varying degrees.After improvement and discharge, two children developed secondary epileptic sequelae.Head CT examination was performed in 20 cases, of which 11 cases showed definite cerebral infarction, eight cases of temporal lobe lesions and three cases of basal ganglia lesions.MRI+ MRA examination of the head in 27 cases showed that there were cerebral infarction and the infarct area large.Conclusion:The high incidence age of cerebral infarction in critically ill children is infantile.The most common diseases are infection, trauma, congenital heart disease, and the first clinical manifestations are convulsion and coma.Imaging examination showed that a high proportion of children had large area infarction, and the diagnostic effect of MRI is better than that of CT.D-dimer may be helpful for early clinical diagnosis.

ABSTRACT

Objective@#To investigate the incidence and clinical characteristics of new-onset organ dysfunction of patients in pediatric intensive care unit (PICU).@*Method@#A retrospective observational study identified all patients admitted to the PICU of Shengjing Hospital Affiliated to China Medical University from January 2015 to January 2016. The functional status score (FSS) was evaluated at admission and hospital discharge respectively, and the difference defined as ΔFSS between the FSS at hospital discharge and the FSS at admission was calculated. According to the initial FSS, the patients were divided into normal group (6-7 scores), mildly abnormal group (8-9 scores), moderate abnormal group (10-15 scores), severe abnormal group (16-21 scores) and extreme severe abnormal group (22-30 scores). According to the primary disease, all cases were divided into cardiovascular disease group, urinary disease group, surgery group, digestive disease group, neurological disease group, respiratory disease group, hematological disease group, poisoning group and other group. According to the FSS domain, all cases were divided into mental status group, sensory group, communication group, motor group, feeding group, respiratory group. The incidence of new-onset organ dysfunction, the case fatality rate and the FSS of each group were calculated. Comparisons were performed using a chi-square test, t test and analysis of variance.@*Result@#The study population included 928 patients (561(60.5%) male, mean age (31.1±1.3) months). The incidence of new-onset organ dysfunction was 8.8%(82/928) and the case fatality rate was 1.3%(12/928). The FSS at hospital discharge(scores), ΔFSS (scores) and the incidence of new-onset organ dysfunction were significantly less in patients in the normal group (6.38±0.17, -0.20±0.17 and 1.3%(3/229), respectively) compared to patients in the mildly abnormal group (7.09±0.27, -1.39±0.27 and 7.2%(12/170), respectively, t=2.36, 3.93, χ2=7.39, all P<0.05), patients in the moderately abnormal group (8.86±0.28, -2.76±0.28 and 10.6%(38/359), t=6.56, 6.91, χ2=17.14, all P<0.05), patients in the severely abnormal group(13.56±0.88, -4.39±0.88 and 24.6%(19/79), t=12.29, 7.13, χ2=42.43, all P<0.05) and patients in the extreme severely abnormal group(18.68±0.99, -6.59±0.91 and 10.9%(10/91), t=18.15, 10.10, χ2=13.27, all P<0.05). Significant difference was found regarding the incidence of new-onset organ dysfunction among patients in cardiovascular disease group (27.3%, 24/88), surgery group (9.2%, 6/65), digestive disease group (8.2%, 8/97), neurological disease group (7.7%, 23/299), respiratory disease group (6.9%, 17/248), hematological disease group (3.9%, 2/51) and toxic group (0, 0/61) (χ2=37.75, all P<0.05). There were significant differences among primary disease groups regarding the FSS at admission, the FSS at hospital discharge, ΔFSS, Δmental status FSS, Δsensory FSS, Δcommunication FSS, Δmotor FSS, Δfeeding FSS, and Δrespiratory FSS (F=13.56, 8.97, 10.84, 6.30, 7.37, 7.84, 7.47, 9.97, 10.50, all P<0.05).@*Conclusion@#The incidence of new-onset organ dysfunction in PICU was high. The case fatality rate in patients with new-onset organ dysfunction was high. The functional status at hospital discharge was strongly associated with the functional status at admission. Patients in the cardiovascular disease group had the highest incidence of new-onset organ dysfunction and the most severe deterioration of functional status.More attention must be paid to motor function and respiratory function in cardiovascular disease, respiratory disease and hematological disease.

ABSTRACT

Objective To investigate the clinical features,pathogenic distribution of children with in-fective endocarditis(IE)during the past 10 years.Methods Medical records of 30 children with IE admitted to Shengjing Hospital of China Medical University from October 2006 to October 2016 were retrospectively analyzed,including the clinical data and pathogenic characteristics.Results Among the 30 cases of IE,there were 18 males and 12 females,age ranged from 2 months to 13 years old.Fever was found as initial symp-toms in 21 cases(70.0%),respiratory symptoms in 4 cases(13.3%),neurological symptoms in 4 cases (13.3%),edema in 2 cases(6.7%),murmur in 1 case,precordial discomfort in 1 case,and peripheral blood cell reduction in 1 case. The most common underlying factor was congenital heart disease(17 cases, 56.7%).Surgery was performed in 6 children due to congenital heart disease before endocarditis.Vegetations were detected on echocardiography in all cases(100%).Blood cultures were positive in 50.0%,Staphylococ-cus aureus was the most common organism,accounting for 6 cases (40.0%).Other notable pathogens in-cluded Streptococcus pneumoniae(4 cases,26.7%),Enterococcus faecalis(2 cases,13.3%),Streptococcus suis(1 case),Streptococcus anginosus(1 case) and Staphylococcus epidermidis(1 case).C-reactive protein was raised in 25 cases(83.3%)at the time of admission.C-reactive protein was higher than 100 mg/L in 8 cases.Conclusion Early clinical manifestations of IE are atypical.Fever is the most common symptom. Congenital heart disease is the major risk factor of IE,Gram-positive cocci is the most common organism. Antibiotic treatment is not effective,then surgical treatment may be considered.

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.
