ABSTRACT
Objective:To analyze the characteristics of ultrasound in children with myocardial hypertrophy and to understand the etiology.Methods:From December 2016 to December 2019 in our hospital, 44 cases of children with ventricular septum and left ventricular posterior wall thickness Z value >2 were retrospectively analyzed.Results:There were 10 cases of hereditary myocardial hypertrophy (22.7%), 6 cases of hypertrophic cardiomyopathy showed asymmetric myocardial hypertrophy, the hypertrophy mainly concentrated in the apex, anterior septum and posterior septum, and the thickened myocardial fibers were disorderly arranged, the myocardial echo was disorderly and uneven; 2 cases had family history but did not do gene detection; 2 cases of glycogen storage disease type Ⅱ showed symmetrical myocardial hypertrophy, enhanced and dense myocardial echo, and progressive myocardial hypertrophy, 1 case was misdiagnosed as hypertrophic cardiomyopathy; 1 case of primary carnitine deficiency showed symmetric hypertrophy of myocardium with dense and uniform echo, which was misdiagnosed as hypertrophic cardiomyopathy for the first time; 1 case was clinically diagnosed as myocardial amyloidosis, symmetric hypertrophy of myocardium, dense and uniform echo, with unique signs of " ground glass degeneration" and granular strong echo. There were 29 cases (65.9%) with acquired myocardial hypertrophy, including 14 cases caused by aortic disease, 1 case with Williams syndrome, showing myocardial thickening mainly with ventricular septum thickening, but without abnormal myocardial echo; 12 cases were mothers with abnormal glucose metabolism during pregnancy, with thickening of interventricular septum and posterior wall of left ventricle without abnormal myocardial echo; 2 cases of renal hypertension showed concentric myocardial hypertrophy. The remaining 5 cases (11.4%) are unknown.Conclusions:The causes of myocardial hypertrophy are complex and diverse. Comprehensive analysis of imaging characteristics and clinical results should be used to identify the cause of the disease as early as possible and take timely intervention to the cause to save the child's life and improve the quality of life.
ABSTRACT
Objective@#To explore the application value of pulmonary ultrasound for the treatment of severe acute respiratory distress syndrome in children with extracorporeal membrane oxygenation(ECMO).@*Methods@#Seven children with severe acute respiratory distress syndrome (ARDS) who were treated with ECMO in the PICU ward of Hunan Children Hospital from August 2018 to March 2019 underwent pulmonary ultrasound before treated with ECMO, after each bronchoscopy and lavage, before ECMO withdrawal, and within 24 hours after ECMO withdrawal. Performance of pulmonary ultrasound and clinical data were retrospectively reviewed.@*Results@#Seven patients treated with ECMO for 11.5(3-27)days, and 1 patient underwent ECMO transport. Six (86.7%) patients were successfully weaned from ECMO, and 1 (14.2%) patient failed to exit ECMO successfully. Four(57.1%) patients were discharged from hospital, and 3(42.8%) patients eventually died. In various diagnostic signs of pulmonary ultrasound were detected in 7 patients, including pulmonary edema (7 cases), lung consolidation (5 cases), followed by pleural effusion (4 cases), atelectasis (3 cases) and pneumothorax (3 cases). Pulmonary ultrasound showed that the lungs were re-expanded and suggested that the child could attempt to evacuate the ECMO.@*Conclusions@#Pulmonary ultrasound can comprehensively evaluate the various lung lesions in children with ECMO treatment, and can dynamically monitor the process of lung recruitment in real time, providing a reference for guiding the evacuation of ECMO.

Objective To explore the application value of pulmonary ultrasound for the treatment of severe acute respiratory distress syndrome in children with extracorporeal membrane oxygenation( ECM O ) . Methods Seven children with severe acute respiratory distress syndrome ( ARDS ) w ho were treated with ECM O in the PICU ward of Hunan Children Hospital from August 2018 to M arch 2019 underwent pulmonary ultrasound before treated with ECM O , after each bronchoscopy and lavage , before ECM O withdrawal ,and within 24 hours after ECM O withdrawal . Performance of pulmonary ultrasound and clinical data were retrospectively reviewed . Results Seven patients treated with ECM O for 11 .5( 3－27) days ,and 1 patient underwent ECM O transport . Six ( 86 .7% ) patients were successfully weaned from ECM O ,and 1 ( 14 .2% ) patient failed to exit ECM O successfully . Four( 57 .1% ) patients were discharged from hospital , and 3( 42 .8% ) patients eventually died . In various diagnostic signs of pulmonary ultrasound were detected in 7 patients ,including pulmonary edema ( 7 cases ) ,lung consolidation ( 5 cases ) ,followed by pleural effusion ( 4 cases) ,atelectasis ( 3 cases) and pneumothorax ( 3 cases ) . Pulmonary ultrasound showed that the lungs were re‐expanded and suggested that the child could attempt to evacuate the ECM O . Conclusions Pulmonary ultrasound can comprehensively evaluate the various lung lesions in children with ECM O treatment ,and can dynamically monitor the process of lung recruitment in real time ,providing a reference for guiding the evacuation of ECM O .
ABSTRACT
Objective To observe the abdominal ultrasonic manifestations of children with Langerhans cells histiocytosis (LCH).Methods Imaging features of histopathologically proved LCH in 28 children were retrospectively analyzed.Results Among 28 eases,multi system involvement was found in 25 cases,while only liver and bile duct involvement were detected in 3 cases.Different degrees of enlarged liver,inhomogeneous echo of liver parenchyma,scattered or diffuse hypoechoic regions were found in all 28 cases.Uneven thickening and echo enhancement of the bile duct wall,as well as local expansion or stricture of bile duct cavity were found in 13 cases.Splenomegaly was found in 17 cases,swelling of the pancreas was found in 5 cases,varying degrees of ascites were found in 13 cases,and hepatic hilar lymphadenectasis were found in 14 cases.Conclusion There are specific ultrasonographic manifestations of LCH in children,which may be helpful to improving diagnostic accuracy of LCH.
