A retrospective study 40 patients with moderate or severe diffuse axonal injury which is defined as posttraumatic coma for over 24 hours without mass lesions or ischemic insults was conducted in order to identify prognostic parameters. The sign of hypothalamic damage and motor reactivities of 40 patients were reviewed and compared to the outcome. The results were as follows ; 1) The ratio of male to female was about 3 to 1 and the peak incidence was at the first decade. 2) Of abnormal brain stem signs, fever of central origin was observed at the early posttraumatic phase and correlated with nonrecovery of consciousness(P<0.05). 3) Of abnormal brain stem signs, abnormal ADH secretion was significantly correlated with nonrecovery of consciousness(P<0.005). 4) Abnormal motor reactivity to pain was significantly correlated with nonrecovery of consciousness(P<0.005). 5) In the group of recovery of consciousness, initial Glasgow coma scale in 40 patients with moderate or severe DAI was significantly correlated with their outcome(P<0.005).

A retrospective study was made in 21 patients who angiographically diagnosed as moyamoya or moyamoya-like disease over the last 10 years. Computed tomography of the patients showed semorrhage, infarction or normal. Carotid angiography revealed various stages unilaterally or bilaterally. Seventy-five percent of the venous phase on the side of arterial occlusion demonstranted some abnormalities. Two children with unilateral abnormality showed arterial occlusion at supraclinoid portion of internal carotid arteries. On the other hand 5 adults with unilateral abnormality showed occlusion at variable sites of internal carotid artery.

Anisakiasis refers to the infestation of humans by species of marine nematode larvae belonging to the subfamily Anisakiae. An acute abdominal symptom may occur after ingestion of raw marine fish containing nematode larvae of the genus Anisakis. Migration of the parasite into the wall of gtomach, small intestine or, less commomly, the colon elicits a striking eosinophilic granulomatous tissue response. A 39 year old man was visited St. Vincent Hospital because of abdominal distension and tenderness. The plain abdominal X-ray showed ileus pattern suggesting intestinal obstruction. Hence we presented a case of intestinal Anisakiasis combined with intstinal obstruction.

OBJECTIVE: We report an investigation of cerebral blood flow(CBF) and the expression of p53 and p21 at peri-infarct area of focal cerebral infarction in rats. METHODS: Adult Sprague-Dawley male rats were used for the experiment. In Group 1(n=7), the right middle cerebral artery(MCA) was coagulated. In Group 2(n=11), the right MCA and common carotid artery(CCA) were coagulated, and the left CCA was occluded for 30 minutes. Cerebral blood flow was measured at two areas, 2mm and 8mm distal to the MCA coagulation site. The rats were killed after 24 hours. After immunohistochemical staining, the width of the p53 or p21 positive area was measured. The p53 and p21 positive glial cells were counted at the peri-infarct area adjacent to the infarction core in Group 2. RESULTS: A focal infarction was found invariably in Group 2. CBF's at 2 mm and 8 mm areas were 8.3+/-2.1, 36.4+/-4.2 in Group 1 and 0.0+/-0.0, 6.7+/-1.5ml/100g/min in Group 2, respectively. All of the measured CBF's except that of the 8mm site in Group 1 were significantly lower than preoperative level(p<0.001), which were between 20.8+/-4.5% and 16.3+/-3.3% of preoperative CBF. The ratio of p21 and p53 positive cells was 1.0+/-0.1. CONCLUSION: We could note that the expression of p53 and p21 was the highest at an adjacent peri-infarct area. The degree of CBF reduction is more responsible for infarction than CBF itself.

Thirty patients of symptomatic unstable, medically intractable, degenerative spondylolisthesis were treated by pedicle screw with intertransverse fusion(ITF) or pedicle screw with unilateral posterior lumbar interbody fusion(UPLIF). In the ITF, multiple corticocancellous bone chips harvested from posterior iliac bone grafted on the decorticated transverse processes and lateral facet joints after adequate decompression. The UPLIF was performed through unilateral route by using two bicortical bone dowels from anterior iliac bone and chip bones from resected lamina. These two treatment modes compared in terms of symptomatic improvement, fusion rate, and other various parameters related with operation. The follow up period was ranged from 8 months to 44 months. Both precedures showed good result in symptomatic improvement(79% in ITF, 88% in UPLIF) and in fusion rate(93% in ITF, 86% in UPLIF). The UPLIF showed shorter hospital stay(16days vs. 25days), shorter operation running time (329min. vs. 469min.), and need less transfusion(1.1pint vs. 3.7pints) compared with the ITF. The complication rates of both procedures were similar(36% in UPLIF) and all complications resolved within 2 months. The major complication of the ITF was persistent back pain, and nerve injury in the UPLIF.

The purpose of this study is to investigate whether paraspinal muscle wasting occurs in association with chronic low back pain(LBP) and to know whether low back muscle exercise is effective for abating chronic low back pain. Cross sectional areas(CSA) of lumbar vertebral bodies and paraspinal muscles were measured using CT at the level of the fouth lumbar vertebral body in 37 patients(23 males 14 females) with acute low back pain and in 44 patients(20 males, 24 females) with chronic low back pin. The results were as follows; 1) The mean age of the patients with chronic LBP were higher than those with acute LBP. 2) The CSAs of L4 vertebral bodies were correlated significantly with body weight and the CSAs of L4 vertebral bodies, erector spinae and psoas muscles were larger in males than in females. 3) The volumes of the paraspinal muscles were significantly reduced in patients with chronic LBP compared to a cute LBP. These changes can cause erector spinae and psoas muscle weakness and disuse atrophy and thereby predispose to spinal instability and progressive dysfuction.

Infantile myofibromatosis is a rare neoplasm which occurs primarily in early infancy and arise in the various sites. A 4-year-old boy, who presented with painless soft scalp mass in the left temporoparietal region was diagnosed to have myofibromatosis and this case is presented with some literature reviews.
