Sleep disorders are common in children and adolescents, especially in those with neurodevelopmental and mental disorders, but treatment strategies remain limited.The main therapeutic methods for sleep disorders in children and adolescents include cognitive behavioral therapy, surgical therapy, drug therapy, and physical therapy.Conventional cognitive behavioral therapy is expensive; plus, the number of qualified sleep physicians and therapists is limited, and patient′s compliance is low.Drug therapy is the most commonly used treatment for insomnia in children and adolescents, but it lacks evidence-based indications and safety and has many adverse reactions, and its long-term efficacy is unknown.Physical therapy that changes the activity of central and peripheral nerves through physical stimulation such as magnetism, electricity, sound and light can provide valuable alternative or complementary treatment for individuals with sleep disorders who can′t get conventional treatment, have poor tolerance or are ineffective.In this paper, 4 common clinical physical therapies (transcranial magnetic stimulation, transcranial direct current stimulation, light therapy, and hyperbaric oxygen therapy) and their application in treating sleep disorders in children and adolescents are reviewed, providing scientific basis and new ideas for the future clinical treatment of sleep disorders in children and adolescents.

Objective To evaluate the safety and effectiveness of modified total arch replacement by retrospectively analyzing the clinical outcome of surgical patients with Stanford type A aortic dissection (AAD). Methods From June 2015 to December 2016, 39 consecutive patients with AAD were recruited to this study. This modified technique was preformed under general anesthesia and a 30℃ hypothermia circulatory arrest (HCA) with continual bilateral antegrade cerebral perfusion. Different surgical approaches were applied according to the aortic root condition: Bentall procedure (4 patients), David procedure (2 patients), aortic valve plasty and ascending aortic replacement (25 patients) and Cabrol procedure (8 patients). Concomitant procedures included mitral valve plasty (1 patient) and tricuspid valve plasty (1 patient). Results The average cardiopulmonary bypass (CPB), aortic occlusion time (ACC), HCA and operation time was 218.5±42.2 min, 134.2±32.4 min, 4.9±2.3 min and 415.5±80.5 min respectively. Four patients required dialysis and 2 patients developed temporary neurological deficit. No permanent neurological deficit, postoperative paraplegia or in-hospital death occurred. Computed tomography examination was performed on all patients before discharge and 3 months after discharge. The follow-up result showed that 37 patients developed complete thrombosis in the false lumen and 2 patients developed partial thrombosis. Conclusion Modified total arch replacement is a safe and effective approach for AAD. It can greatly avoid postoperative complications and provide satisfactory short-term outcomes.

Objective     To retrospectively reviewed our experience of the surgical and perioperative treatment of patients suffering from critical Marfan syndrome with severe left ventricular dysfunction and to evaluate its therapeutic effect and prognosis. Methods     Between January 2012 and October 2016, 15 patients diagnosed with Marfan syndrome combined with severe left ventricular dysfunction (left ventricular ejection fraction≤40% or left ventricular end diastolic diameter≥75 mm) underwent operations for aortic root aneurysm in Zhujiang Hospital and Guangdong General Hospital. Among them, 11 were males and 4 were females with a mean age of 32.9±8.7 years ranging from 19 to 55 years. Five patients with aortic dissection underwent Bentall procedure and total arch reconstruction with stent graft implantation. Two patients underwent Bentall procedure and hemi-arch replacement, seven patients underwent Bentall procedure and one patient underwent Cabrol procedure. Concomitant procedures included mitral valve repair in 12 patients, mitral valve replacement in 3 patients and tricuspid valve repair in 12 patients. Results     There were 11 patients (73.3%) receiving intra-aortic balloon pumping implantation. One (6.7%) in-hospital death occurred. The left ventricular end diastolic diameter decreased from 80.5±7.4 mm to 58.3±6.0 mm (P<0.05) and the left ventricular ejection fraction improved from 37.3%±5.2% to 46.3%±4.4% 3 months postoperatively (P<0.05). The left ventricular end diastolic diameter decreased from 80.5±7.4 mm to 53.7±3.6 mm (P<0.05) and the left ventricular ejection fraction improved from 37.3%±5.2% to 57.7%±4.2% after one year (P<0.05). No death and reoperation occurred in the follow-up. Conclusion     Although the patients with Marfan syndrome and severe left ventricular dysfunction usually have a high surgical mortality, the key to satisfactory outcomes of severe Marfan syndrome is adequate preoperative preparation, complete correction of all vascular lesions during the operation, application of circulatory auxiliary device and perioperative strict and long-term ICU monitoring.
