Diastematomyelia is a rare congenital anomaly characterized by a division of the spinal cord or the filum terminale into two parts. In Korea, only one case has been reported. The authors have operated on 5 cases of diastematomyelia with septum since July, 1978. The ages ranged from 1 to 44 years (median; 11 years). There were 2 boys, 2 girls and an adult man. The disease manifested by cutaneous abnormalities and neurological or orthopedic deficits. Pain was a chief complaint in the adult patient. The symptoms had progressed in 3 cases. The diagnosis was made correctly by CT myelography or MRI in 4 cases. The median septum was located at the lumbar area in 4 cases and at the lumbosacral region in 1 case. Associated abnormalities included low lying conus (5 cases), lipoma (2 cases), thickened filum terminale (1 case), hemilipomyelomeningocele (1 case) and syrinx (1 case). The median septum was removed. The dural sleeve adjoining the septum was resected and the dural sac was reconstructed. The role of MRI in the diagnosis and planning of surgery and the high frequency of associated low lying conus were emphasized. Though the surgical treatment relieved pain, it did not reverse the neurological deficits or orthopedic deformities significantly, which suggests the beneficial effects of early surgical intervention in the cases with progressive symptoms.

This is a clinical study on 72 cases of purpura hospitalized at Han Il Hospital during the period from Jan., 1970 to Dec, 1979. The authors obtained the following results : 1) Allergic purpura (25 cases, 34.7%) was the most common disease, followed by I.T.P. (20 cases, 27.8%), Ieukemia (10 cases, 13.9%), meningoccemia (7 cases, 9.7%), and aplastic anemia (5 cases, 6.9%) in order of frequency. 2) The most prevalent age group was 6 to 9 one (45 cases), and sex ratio of male to female revealed 1.67 : 1(45:27). 3) The main clinical features in thrombocytopenic purpura were anemia abdominal pain fever and epistaxis ; while those in non-thrombocytopenic purpura were abdominal pain fever melena hematuria and headache. 4) The hemoglobin level was below 7 gm.% in leukemia and aplastic anemia, but normal or slightly decreased in allergic purpura and idiopathic thrombocytopenic purpura. The W.B.C. count was markedly increased in the most cases of sepsis and leukemia, decreased in aplstic anemia, and within normal range in allergic purpura. The platelet count was below 10,000/mm2 in 97% cases of the thrombocytopenic purpura, while within normal range in non-thrombocytopenic purpura. 5) The bleeding time and the clotting time were within normal ranges in most of all cases. The Rumpel-Leede test revealed positive result in 85% cases of I.T.P., while in only 20% of allergic purpura.

Osteochondromas make up about 30% to 40% of benign bone tumors. Most are solitary lesions but some are multiple, usually with autosomal dominant inheritance. From 1% to 4% of osteochondromas occur in the spine, where they can cause a variety of signs and symptoms, including those of spinal cord compression. Isolated osteochondromas are usually of little significance. However, if they are located near neural structures, they may cause irritation due to mechanical compression. In patients with hereditary multiple exostoses who present with neck or back pain, and particularly in those who have neurologic symptoms in the upper or lower extremities, a diagnosis of intracanalicular osteochondroma should be presumed until proven otherwise. Computerized tomography(CT) and MRI are the imaging procedures of choice. Prompt surgical excision affords the best prognosis for these patients who have spinal cord compression secondary to intracanalicular osteochondroma.

OBJECTIVES: Stroke is leading cause of death and more importantly it is cause of serious disability. The effective treatment of acute ischemic stroke still remains a challenge to modern medicine. Recent clinical trials have shown that carotid endareterctomy(CEA) provide overwhelming benefits compared with medical therapy in preventing subsequent stroke for symptomatic carotid stenosis. For the asymptomatic ones, the data are less compelling, but highly suggestive that CEA do have benefits in properly selected patients. MATERIALS AND METHODS: To investigate the clinical manifestations of carotid stenosis and results of CEAs, authors analyzed retrospectively 19 CEAs in 16 patients from June 1986 to June 1999. Age of patients ranged from 55 to 76 years(median, 66) and male to female ratio was 14 to 2. The duration of follow-up was 1 to 144 months (median, 26). All of CEAs were done on the side of stenosis more than 80% and bilateral CEAs were done in three. Six CEAs were performed in asymptomatic patients. RESULTS: Seventeen of 19 CEAs showed excellent results and complication rate was low although ipsilateral ischemic stroke occurred in two. CONCLUSION: CEA may be a valuable surgical treatment for ischemic stroke caused by carotid stenosis and also for prevention of stroke of asymptomatic patients with carotid stenosis.

Spinal osteochondroms are very rare, and are thought to arise through a process of progressive endochondral ossification of aberrant cartilage of a growth plate, as a consequence of congenital defect or trauma. A case of diffuse type osteochondroma involving the posterior elements of L1-L5 that progressed after laminectomy in a 33-year-old man is reported. Usually, the spinal osteochondroma shows clear demarcation between tumor margin and normal spine elements, and can be exised completely. However, there was no clear demarcation between tumor and normal spine element in our case and therefore it was not possible to removal completely.
