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.

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.

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.

Carcinoid tumors arise from enterochromaffin cells that are located predominatly in the gastrointestinal mucosa. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the museular wall of the rectum should be considered malignancy and treated by more radical surgery such as abominoperined resection. We report 6 cases of rectal carcinoid tumor, three cases of them were less than 1 cm in size without metastasis. Two of these, small carcinoid tumor were treated with endoacopic polypectomy and one was treated with segmental resection. The others were 2.0 cm or larger in size with regional or liver mestasis. They were treated with segmental resection or electrical fugalization for tumor and transcatheter arterial embilization for liver metastasis or none.

We report five patients of esophageal injuries confirmed by clinical signs and radiological evidences. They include a partial tear and a perforation which were not noticed during the operation, a perforation which was primarily repaired during the operation, and two perforations which occurred during the reoperations for the removal of mal-positioned screws or plate. The partial tear was not repaired. The perforation which occurred during the operation was primarily sutured and didn't receive further treatment. Two perforations which occurred during the reoperations were treated by irrigation, debridement with surgical drainage, and systemic antiobiotics. One who was diagnosed later after the operation showed the poorest outcome and required longest hospital days among our series. Early detection and appropriate treatment of esophageal injury following anterior spinal surgery can only improve the prognosis by preventing secondary complications.

OBJECTIVE: Posterior lumbar interbody fusion(PLIF), the current leading method of pedicle screw fixation combined with interbody fusion via posterior route, sometimes requires too much destruction of the facet joint than expected especially for the patient with a narrow spine. On the other hand, tranforaminal lumbar interbody fusion(TLIF) technique provides potential advantages over PLIF and can be chosen as a better surgical alternative to more traditional fusion methods in certain surgical conditions. METHODS: From October 1999, 99 PLIF and 29 TLIF procedures were done for the patients with spinal stenosis and instability. Radiological data including the interpedicular distance and the size of the pedicles as well as the clinical parameters were collected retrospectively. The degree of resection of the inferior articular process was compared with the interpedicular distance in each patient who received PLIF. RESULTS: No significant differences were found between PLIF and TLIF regarding the operation time, blood loss, duration of hospital stay, or short term postoperative clinical result. There were no complication with TLIF, but PLIF resulted in 9(9.1%) complications. During PLIF procedure, all patients(n=24) except one with the interpedicular distance shorter than 27mm required near complete or complete resection of the inferior articular processes, whereas only 6(31.5%) of 19 patients with the interpedicular distances longer than 30mm required the similar extent of resection. CONCLUSION: TLIF is better than PLIF in terms of the complication rate. The patient who had narrow interpedicular distance(<27mm) might be better candidate for TLIF.
