ABSTRACT
The purpose of this article is to explore the diagnosis of Internet addiction （gaming disorder） and its research hotspot. Gaming disorder is basically an addictive behavior and is reinforced by obtaining positive emotion and alleviating negative experience. By introducing a complex comorbidity clinical case， this article talked about addictive behavior， gaming disorder and other related issues， and discusses the debate of the diagnosis of gaming disorder and its possible future changes， the treatment， the current main problems and research hotspot.
ABSTRACT
Objective To explore the diagnosis and surgical treatment experience of vascular ring in infants and children.Methods Fourteen cases (9 boys and 5 girls,aged 2 months to 6 years,weighted 4.5 - 15.0 kg) with vascular ring were diagnosed and treated surgically in Children's Hospital of Chongqing Medical University from Sep.2009 to Dec.2010.All children underwent X-ray,echocardiography and spiral computed tomography examination preoperatively.Bronchoscopy and barium swallow was performed in 5 cases respectively.The pathological types of vascular rings included double aortic arch in 1 ( 7.1％ ),pulmonary artery sling in 7 (50.0％),right aortic arch with left patent ductus arteriosus or persistent left ligament in 6 (42.9％).Associated cardiac anomalies were present in 7 (50.0％) patients.Tracheal stenosis of different length ( 12％ -62％ ) and severity (45％ -74％ cross-sectional luminal narrowing) was observed in the group.Barium swallow in 5cases showed localized compression of the esophagus.12 cases underwent repair of vascular ring with cardiopulmonary bypass (CPB),and the associated congenital heart defects were repaired simultaneously.2 cases of right aortic arch with left patent ductus arteriosus or persistent left ligament underwent surgery without CPB.Results The median duration of CPB in 12 cases and aortic cross-clamp time in 7 patients were 77.5 minutes ( range:55 - 186 minutes) and 36 minutes ( range:22 - 110 minutes) respectively.The median duration of postoperative ventilation and ICU stay were 21 hours (range:7 -308 hours) and 79.5 hours (range:16-314 hours) respectively.One baby with pulmonary artery sling died on the postoperative 12th day ( in-hospital mortality 7.1％ ).Of the 13 cases discharged from the hospital,1 case were lost to follow up.In the follow-up ( 1- 15 months) of 12 cases,digestive symptoms were disappeared.Development,exercise tolerance and symptoms showed obvious improvement,although 5 (41.7％) patients had residual respiratory problems.Conclusion Prolonged or recurrent aerodigestive issues in children should alert the pediatrician to the possibility of a vascular ring.Multislice spiral CT scanning is the best imaging modality.All vascular rings should be surgically corrected,and the associated long-segment severe tracheal stenosis needs.The short to midterm outcomes of surgical division are excellent.
