Résumé
Objective To evaluate the effect of different kind of intravenous immunoglobulin (IVIG) therapy in treating Kawasaki disease (KD) and preventing cardiac consequences (coronary artery lesion, CAL). Methods A questionnaire form and guideline for KD diagnosis were sent to 50 hospitals providing pediatric medical care in Shanghai. The data from a total of 1 682 KD patients were collected. It included 1 064 males and 618 females from 1998 through 2008 in Shanghai. The average age of the KD patients was (2.57±2.33) years old (0.1-18.8 years).The patients had been divided into 6 groups for different IVIG therapy, which included 1 g/kg once, 2 g/kg once, 0.4-0.5 g/kg five times, 1 g/kg twice, 2 g/kg twice and others. SAS 6.12 software was used for statistical analysis. Results In all KD patients, the patients treated with IV1G in 5th-10th day of illness has the least cardiac complication and CAL incidence and the group with IVIG therapy of 1 g/kg twice also has the least cardiac complication and CAL incidence. Conclusions The best doses of IVIG in treating KD is 1 g/kg twice and the IVIG therapy should be used in 5th-10th day of KD illness.
Résumé
PurposeTo evaluate and describe fetal cardiac development and hemodynamics high risk pregnancy by using ultrasound technique. Methods Two-hundred and thirty-three pregnancies were prospectively studied by using the detailed fetal echocardiographic procedure( fetus gestational age from 19 weeks to 39 weeks). Cardiac chamber size, internal diameter of great arteries were documented together with the presence of inflow and outflow wave patterns. In utero diagnoses of variety of congenital heart defects were also conducted. ResultsCardiac chamber size and internal diameter of great arteries showed a positive correlation with the increasing of gestational age. Left and right ventricles were demonstrated the same size during whole fetal observational period. Blood flow through mitral valve and tricuspid valve were typically 'M' type. By comparing 'e' wave and 'a' wave, this inflow blood velocity pattern was dominant by 'a' wave, though the ratio of a/e gradually decreased during the fetal development period. Blood velocity in aorta and pulmonary artery remained steady along with the gestational age. The detection rate of verity types of congenital heart diseases in this sample population was 5.7% (13 cases) ,the major problem was the complex heart malformation. The occurrence of fetal cardiac arrhythmia was 14 cases (16 % ), with the majority of atrial premature beat. Conclusions Fetal echocardiography can be used to evaluate and monitor the change of cardiac anatomy, structure and hemodymanics during the different gestational age. This has provided a new approach to the further understanding of fetal cardiac development, and is importantto the screening of congenital heart disease during pregnancy.
