The authors conducted a study on children undergoing treatment at major school refusal treatment centers in Hiroshima Prefecture. On the whole, school refusal in the prefecture was found to peak between 13 and 14 years of age. By age group, the main reason for school refusal in elementary school group was parent-child relationship with separation anxiety.(More)
A number of approaches have been put forward to monitor spinal cord ischemia during thoracic and thoracoabdominal aortic occlusion. However, none of these can ultimately prevent devastating complications which result from ischemic spinal cord injury. A direct measurement of the oxygen content of the spinal cord may accurately indicate the perfusion state,(More)
Experiments were undertaken to determine the relationship between evoked spinal cord potential (ESP) and the partial pressure of oxygen in tissue in the epidural space (E-pO2) during aortic clamping. Eighteen adult mongrel dogs were studied as follows. In group I (n = 6), the descending thoracic aorta was clamped partially at the proximal site for 15 min to(More)
OBJECTIVES to study whether spinal cord-feeding arteries could be identified by the changes in the intrathecal pO2 (I-pO2), and to examine whether selective perfusion of feeding arteries identified by this method could protect the spinal cord against ischaemia. DESIGN controlled animal experiments. MATERIALS AND METHODS in experiment 1, using 16 mongrel(More)
