The report presents a definition and causes of syncope in children. Syncope differs from other states with loss of consciousness by causes leading to decreased perfusion and resultant transient cerebral dysfunction with decreased muscle tone. The most common causes of syncope noted in almost 15% of children are neurocardiogenic. This group includes vasovagal, carotid sinus reflexive, situational (coughing, dysphagia, micturation and defecation disturbances) and post-exercise syncope. Another group is represented by orthostatic syncope that may be triggered by primary and secondary dis-autonomy, decreased blood volume (hemorrhage, diarrhea, Addison's disease), some medications and substances of abuse (alcohol). An important group, accounting for 2%-6% of all cases, are cardiogenic syncope, caused mainly by congenital/acquired obstructive cardiac sub- and valvar heart defects, various cardiomyopathies, some heart tumors (e.g. myxoma), exudative pericarditis, pulmonary embolus and hypertension, congenital and acquired coronary anomalies, various significant brady-tachyarrhythmias (sick sinus syndrome, supra- and ventricular tachycardias, congenital and acquired atrio-ventricular blocks). Subclavian steal syndrome as the cause of syncope is exceptional in children. Syncope does not include loss of consciousness due to neurological and metabolic (hypoglycemia) causes, hypoxia, hyperventilation with hypocapnia or CO intoxication. Differential diagnosis should also include pseudo-syncope (hysteria). Preliminary diagnostic management should include a detailed medical history, including family history, on the frequency and circumstances of syncope, sudden deaths, a physical exam with orthostatic assessment of peripheral blood pressure and standard ECG (heart rate, intraventricular and atrioventricular conduction defects, cardiac hypertrophy, arrhythmias, L-QT, changes in ST-T). Further specialist tests depend on preliminary findings.

In Japan, the number of patients with cancer is increasing drastically with the increase in number of elderly people. Therefore, recently, the necessity of rehabilitation for cancer patients has been realized. Cancer rehabilitation can be classified as preventive, restorative, supportive, or palliative and is administered according to the degree of cancer progression. Rehabilitation is of great significance even for patients with progressive cancer as it helps maintain their quality of life. Various forms of impairment, disability, and handicap are associated with cancer rehabilitation. Examples of impairments that cancer patients experience are hemiplegia and higher brain dysfunction in brain tumor cases, paraplegia and quadriplegia in spinal or spinal cord tumor cases, neuropathy and radiculopathy in cases of tumor invasion, complications after surgery, peripheral neuropathy after chemotherapy, and dysphagia after radiotherapy. It is important to evaluate these impairments and the risks associated with rehabilitation.
