In Japan problems of the pediatric emergency-care system have recently increased the needs of consultation to deal with the growing anxiety of parents about how to raise their children and have decreased the number of pediatricians. We believe that one solution is to make pediatric primary care a required part of postgraduate clinical training and thereby increase the ability of nonpediatricians to provide pediatric primary care and to support the care of children. We hope that postgraduate clinical training programs will be reformed so that physicians of all departments can contribute to improving pediatric primary care.

Prosthetic graft replacement for thoraco-abdominal aneurysm was performed in a 69-year-old man. Fever and CRP elevation developed 8 days after the operation. A subcutaneous abscess was found in the wound. The culture of pus and thoracic discharge revealed methicillin-resistant staphylococcus aureus (MRSA). Infected tissues were debrided and an omentopexy was performed without removing the prosthetic graft to avoid spinal cord ischemia. The thoracic cavity was irrigated continuously with 1% Povidone-iodine for three days. The infection subsided gradually and the patient was discharged. Graft infection due to MRSA has recently increased and we experienced such a case which we treated successfully by complete debridement, omentopexy and continuous irrigation.

A 60-year-old woman with acute Stanford type A dissecting aneurysm underwent Dacron graft replacement of the total aortic arch combined with the modified elephant trunk technique. Follow-up CT and angiogram demonstrated blood flow into the false lumen from the distal anastomosis. In order to interrupt the blood flow, endovascular stent grafting was undertaken. She recovered uneventfully, and was discharged on the 14th postoperative day. Follow-up CT taken in the third postoperative month demonstrated exclusion of the blood flow into the false lumen of descending thoracic aorta. Aortic arch replacement followed by endovascular stent grafting of the descending thoracic component is a potential therapeutic option in patients with dissecting aneurysm.

PURPOSE: The pathological mechanism of lumbar spinal stenosis is reduced blood flow in nerve roots and degeneration of nerve roots. Exercise and prostaglandin E1 is used for patients with peripheral arterial disease to increase capillary flow around the main artery and improve symptoms; however, the ankle-brachial index (ABI), an estimation of blood flow in the main artery in the leg, does not change after treatment. Lumbar spinal nerve roots contain somatosensory, somatomotor, and unmyelinated autonomic nerves. Improved blood flow by medication with prostaglandin E1 and decompression surgery in these spinal nerve roots may improve the function of nerve fibers innervating muscle, capillary, and main vessels in the lower leg, resulting in an increased ABI. The purpose of the study was to examine whether these treatments can improve ABI. MATERIALS AND METHODS: One hundred and seven patients who received conservative treatment such as exercise and medication (n=56) or surgical treatment (n=51) were included. Low back pain and leg pain scores, walking distance, and ABI were measured before treatment and after 3 months of conservative treatment alone or surgical treatment followed by conservative treatment. RESULTS: Low back pain, leg pain, and walking distance significantly improved after both treatments (p<0.05). ABI significantly increased in each group (p<0.05). CONCLUSION: This is the first investigation of changes in ABI after treatment in patients with lumbar spinal stenosis. Improvement of the spinal nerve roots by medication and decompression surgery may improve the supply of blood flow to the lower leg in patients with lumbar spinal stenosis.

PURPOSE: To examine the effects of conservative and surgical treatments for nocturnal leg cramps in patients with lumbar spinal stenosis (LSS). Nocturnal leg cramps is frequently observed in patients with peripheral neuropathy. However, there have been few reports on the relationship between nocturnal leg cramps and LSS, and it remains unknown whether conservative or surgical intervention has an impact on leg cramps in patients with LSS. MATERIALS AND METHODS: The subjects were 130 LSS patients with low back and leg pain. Conservative treatment such as exercise, medication, and epidural block was used in 66 patients and surgical treatment such as decompression or decompression and fusion was performed in 64 patients. Pain scores and frequency of nocturnal leg cramps were evaluated based on self-reported questionnaires completed before and 3 months after treatment. RESULTS: The severity of low back and leg pain was higher and the incidence of nocturnal leg cramps was significantly higher before treatment in the surgically treated group compared with the conservatively treated group. Pain scores improved in both groups after the intervention. The incidence of nocturnal leg cramps was significantly improved by surgical treatment (p=0.027), but not by conservative treatment (p=0.122). CONCLUSION: The findings of this prospective study indicate that the prevalence of nocturnal leg cramps is associated with LSS and severity of symptoms. Pain symptoms were improved by conservative or surgical treatment, but only surgery improved nocturnal leg cramps in patients with LSS. Thus, these results indicate that the prevalence of nocturnal leg cramps is associated with spinal nerve compression by LSS.
