BACKGROUND & PURPOSE: The aim of our study is to evaluate the stroke pattern, the correlation of collateralization with cerebral perfusion and stroke severity, and the utility of transcranial Doppler(TCD) to detect collateral pathways in patients with internal carotid artery(ICA) occlusion in the neck. METHODS: Thirty-six patients(28 men and 8 women, mean age of 59.6 ? 12.9 years) with ICA occlusion confirmed by transfemoral cerebral angiography(25 patients) or magnetic resonance angiography(MRA, 11 patients) were studied retrospectively. They had no potential cardiac source of stroke. We evaluated the pattern of cerebral infarcts by magnetic resonance imaging, and the number and the patency of collateral vessels, and the degree of perfusion through collaterals by cerebral angiography. The collateral vessels detected by TCD and MRA were compared with those by cerebral angiography. RESULTS: We found territorial infarcts in 23 patients(64%) and borderzone infarcts in 15(42%). Territorial infarcts(p<0.0001) and borderzone infarcts(p=0.02) occurred more in the ipsilateral hemisphere to the occluded ICA. The prevalence of small subcortical infarcts did not differ between hemispheres. Collateralizations through leptomeningeal anastomosis(p<0.01) and ophthalmic artery(OA, p<0.05) were associated with angiographically reduced cerebral perfusion. Collateralization through OA was also associated with severe symptomatic group(p<0.05); and collateralization through anterior or posterior communicating artery was associated with mild symptomatic group with marginal statistical significance(p=0.097). The number of collateral vessels was associated with neither the degree of perfusion nor the stroke severity. The sensitivity and specificity of TCD to detect collateralization through anterior communicating artery were 100% and 78%, through posterior communicating artery, 67% and 75%, and through OA, 67% and 63%, respectively. CONCLUSION: Cerebral infarcts related to a proximal ICA occlusion are more likely to be ipsilateral territorial or borderzone. The type of collateralization is more important factor for cerebral perfusion and stroke severity than the number of collateral vessels. TCD is a reliable tool for the evaluation of the collateral vessels in the patients with ICA occlusion.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.

461 cases of renal biopsy specimens were summerized correlated with their light microscopic and immunofluorescence findings, which obtained from Jan. 1981 to Jul. 1986 at Department of Pathology, Kyung Hee School of Medicine, The results were as follws: 1) The incidence of IgM nephropathy was about 5.8% of the primary glomerulopathy. 2) Sex distribution showed male preponderance with male: female ratio of 1.7:1. 3) Age distribution were 0-9 years 7.4%, 10-19 years 29.6%, 20-29 years 37.0%, 30-39 years 7.4%, 40-49 years 7.4% and 50-59 years 11.1%. 4) The clinical symptoms were gross hematuria 7.4%, microscopic hematuria 59.2%, proteinuria (nonnephrotic) 37.0%, nephrotic syndrome 55.5%, hypertension 7.8% and edema 59.2%. 5) 9 cases (33.3%) had past histories of upper respiratory infections. 6) The distributions of the light microscopic deagnosis were minimal histologic change 11 cases (40.7%), focal glomerulonephritis 7 cases (25.9%), measangial proliferative glomerulonephritis 5 cases (18.5%), focal and segmental glomerulosclerosis 1 case (3.7%) and poststreptococla glomerulonephritis 1 case (3.7%). 7) Immunofluorescence study showed significant diffuse mesangial granular deposits of IgM and C3 in all of the 27 cases. 8) It was demonstrated that in the patients with nephrotic syndrome, the prognosis for the patients with IgM deposition were less favorable than those without IgM deposition.

The tibial plateau fracture is a fracture of the proximal end of the tibia, involving the weight bearing articular surface. This fracture often presents some problems in treatment and prognosis, because it is frequently accompanied by soft tissue injuries such as collateral ligament, cruciate ligament and menisci. During a period of 3 1/2 years, from Febuary 1980 to July 1983, We observed 78 cases of tibial plateau fractures at Gang Nam Sacred Heart Hospital. Of the above cases, 40 could be followed for a period of anywhere from 3 months to 3 years. They have been analysed according to the cause, classification, method of treatment and final result of treatment. Among these 21(52.5%) were treated by cast immobilization, 3(7.5%) by skeletal traction, 16 (40%) by open reduction and internal fixation. Thirty two cases (80% ) out of 40 indicated the result of the Acceptable group according to Hohl and Lucks criteria.

Takayasu arteritis is a chronic non-specific inflammatory arteriopathy that involves primarily the first branches of aortic arch but may also affect the aorta and any of its primary branches. A characteristic trait of the disease is that most of the patients are young females of mainly Asian and South American origin. Recently, we experienced a rare case of Takayasu arteritis which showed a cord-like atresia of abdominal aorta just below renal arteries in 52-year-old woman. We performed a side to side bypass graft from descending thoracic aorta to abdominal aorta just above the aortic bifurcation with a 18mm PTFE(polytetrafluoroethylene) vascular graft. The postoperative course was uneventful.

BACKGROUND: In November 2016, an outbreak of scombroid fish poisoning occurred among elementary school students in Seoul, Korea. An epidemiological investigation was conducted to identify the cause and source of the illness. METHODS: A case-control study was conducted among school members who had eaten lunch in the school. The histamine level in the suspect food item (yellowtail steak) was measured. RESULTS: Fifty-five (5.4%) of 1,017 school members who consumed fish for lunch fell ill. The principal symptoms were flushing (100%) and headache (72.7%); the median incubation period was 40 minutes. All had consumed yellowtail steak (odds ratio, 9.24; 95% confidence interval, 1.22–69.91). Leftover steak had an elevated histamine level (293 mg/kg), higher than the allowed 200 mg/kg. CONCLUSION: An outbreak of scombroid fish poisoning was confirmed; this is the first such report in Korea. Detailed food safety guidelines must be established.

Trichuriasis is an intestinal infection of human beings caused by Trichuris trichiura, more commonly known as whipworm because of its whip-like appearance. It is characterized by the invasion of the colonic mucosa by the adult trichuris. It is prevalent throughout the world, especially in tropical areas. Diagnosis is made typically by the identification of characteristic barrel-shaped eggs in the feces, although adult worms may be seen rarely at sigmoidoscopy or colonoscopy. We report five cases of whipworm infection that was diagnosed on colonoscopic examination.
