Endovascular embolism technique has been demonstrated to be the best initial option for treatment of carotid cavernous fistula (CCF). Several large series re ports have shown that most CCFs can be successfully occluded via transarterial or transvenous endovascular approach.1-6 This paper reports a case of C CF recurred after endovascular occlusion of internal carotid artery (ICA) proxim al to the fistula. A new technique has been described for transarterial emboliza tion with tungsten microcoils via surgical exposure to ICA, which has not been r eported previously in the literatures.

Hydraulic spinal cord and cauda equina nerve injuries are very uncommon. Since 19 96, we have received and treated 4 patients with hydraulic spinal cord and cauda equina injuries. Thisreport gives a detail description.Four patients with hydraulic spinal cord and cauda equina nerve injuries, male: 3, female: 1, aging 13-56 years have been treated in our hospital since 1996. E xtradural blocking injury was in 1 patient, extradural anaesthesia injury in 1 p atient and intraspinal canal myelography injury in 2 patients; the segments of i ntraspinal canal were L2-3 and L3-4. One patient was accompanied b y femoral fracture, 2 patients by intraspinal tumor and 1 patient had operat ion because of prolapse of lumbar intervertebral disc.

Eosinophilic ulcer of oral mucosa (EUOM) is a nonspecific clinical appeara nce, which appears to be frequently unrecognized or misdiagnosed usual ly as squamous cell carcinoma (SCC), especially in old patients. It i s a rare self-limited benign ulcerative disease, and it is characterized with t he infiltration of eosinophilic leukocytes mixed with other inflammatory cells, 1,2 such as th e mitotically active large mononuclear cells with round or ovoid pale nu cleus. This cell type, often interpreted as a histiocyte, confounds the histolog ic evaluation and occasionally leads to the erroneous diagnosis of lymphohistioc ytic malignant condition. Although it has assumed that trauma is an important et iologic factor, the exact pathogenesis remains unclear.3 The morbidity of this disease is low and there are few Chinese literatures about it,4 so it is n ecessary to pay more attention to it. In this article, 3 out of 5 cases of EU OM are misdiagnosed as SCC, and we will report the records in order to identify it from SCC well.

Traumatic brain injury (TBI) is a major public health problem throughout the worl d. More than 400000 patients with TBI in the United States of America and more than a million patients with TBI in China are admitted to hospital every ye ar. Head trauma is also No.1 killer of young people in the developed countries as well a s in some developing countries. Unfortunately, the outcome of patients with seve re TBI is still poor all over the world. The mortality of severe TBI patients (G CS 3-8) in majority of hospitals is over 30% and very severe TBI patients (GCS 3-5) is over 80% with only 15% functional recovery.1,2 However, recent ad vance in cerebral protection by mild (35-33℃) to moderate hypothermia (32-30 ℃) is certainly encouraging, which brings neurosurgeons the hope to improve the outcome of severe head injured patients.

The 20th century is a century in which human material civilization and medicine d eveloped the most rapidly, many causes of diseases unknown before were found mol ecularly, many diseases or terminal diseases uncurable before were cured with ne w therapeutic methods, many fatal contagious diseases that had caused corps over the wilderness were controlled effectively, catheter techniques and operations could be used anywhere in the human body so long as they were needed, and new di agnostic and therapeutic techniques emerged one after another; medical progress made an ever-lasting contribution to human health.

Atotal of 62 papers have been published in the Chinese Journal of Traumatology (E nglish Edition) (CJT), covering scope of both basic scientific and clin ical study of traffic, craniocerebral, thoracic, extremity, spi nal and spinal cord injuries. Most of them have revealed the latest findings of basic scientific research or clinical treatment on traumatology in China, which, at the same time, play an indispensable role in communication with the foreign researchers.
