Spinal cord herniation is a rare condition that has become increasingly recognised in the last few years. The authors report a case of idiopathic spinal cord herniation in a 33 year old woman performed with progressive Brown-Sequard syndrome. The diagnosis was made on MR imaging. After repairing the herniation, the patient made a gradual improvement. Potential causes are discussed, including a possible role of dural defect. In conclusion, idiopathic spinal cord herniation is a potentially treatable condition that should be more readily diagnosed that increasing awareness and improved imaging techniques.

Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Charcot spine is a progressive and destructive process that affects the vertebral bodies, intervertebral discs, and posterior facets. It is the result from repetitive microtrauma in patients who have decreased joint protective mechanisms due to loss of deep pain and proprioceptive sensation, typically because of spinal cord injury. The objective of the study is to report an unusual case of Charcot spine, as a late complication of traumatic spinal cord injury, treated by a circumferential arthrodesis performed with a single staged posterolateral costotransversectomy approach.

Cardiac Myxoma is a most frequent benign tumor in primary cardiac tumors. About 75% occur in the left atrium & 20% in the right atrium, ventricular Myxoma is a very rare one among the cardiac myxoma. They may cause severe and progressive disease resembling valvular heart disease. With the advent of various diagnostic modalities, especially real time bidimensional echocardiography enabled us more accurate diagnosis of cardiac myxoma noninvasively and preoperatively. From April 1977 to Sept. 1981, 16 cases of cardiac myxomas were operated in Seoul National University Hospital using cardiopulmonary bypass. There were 13 cases of left atrial myxomas and each of a case was right atrial and right ventricular and left ventricular one. In all cases tumors were resected successfully & were discharged in healthy state. Follow up results of each patient was excellent.

Takayasu`s arteritis is a non-specific arteritis involving the aorta and its major branches. Because of the complexity in the feature of vessel involvement, it represents various clinical presentations according to the sites of involvement. In general, the medical and the surgical treatment of this progressive disease are known to be unsatisfactory but the surgical treatment can provide symptomatic relief and prolong life in selected cases. Recently we experienced one case of Takayasu`s arteritis involving the aortic arch and its major branches. A 45 year-old male patient admitted with the complaints of dizziness, headache, visual disturbance and coldness of upper extremities. Ascending aortogram revealed total occlusion of innominate artery and near total occlusion of left common carotid artery at the site of origin of both vessels. Under the clinical diagnosis of Takayasu`s arteritis, aorto-bicarotid-right subclavian bypass was performed. Postoperative course was uneventful and most of symptoms were relieved except mild residual visual disturbance.

Coronary artery disease has historically been a contraindication to lung transplantation. We report a successful combined bilateral lung transplantation and off-pump coronary artery bypass in a 62-year-old man. The patient had a progressive decline in lung function due to idiopathic pulmonary fibrosis and a history of severe occlusive coronary artery disease.

Colchicine is widely used in the treatment of gouty arthritis, and chronic use of colchicine can cause vacuolar myopathy. We report colchicine-induced myopathy with electrophysiological myotonia in a patient with gouty arthritis. A 86-year-old man with gouty arthritis presented with progressive proximal weakness and gait disturbance. Electrophysiological finding showed myotonic myopathy and muscle biopsy revealed a vacuolar myopathy. His symptoms soon resolved with the discontinuation of colchicine.

By definition, the time to reach nadir in Guillain-Barre syndrome (GBS) is within four weeks. This is in contrast to the chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), which progress for at least two months. However, CIDP can take a relapsing and remitting form and could mimic treatment related fluctuations of GBS (GBS-TRFs) especially during the early phase of disease. We report a patient with CIDP who initially presented with a rapidly progressive limb weakness mimicking GBS, but finally showed good recovery after long term corticosteroid therapy.

Ullrich congenital muscular dystrophy (UCMD) is caused by mutations in one of three genes encoding collagen VI. Although UCMD usually shows an early onset, progressive weakness, contractures and hyperlaxity of the joints, and respiratory failure, it is well known to exhibit a wide spectrum of clinical severities. The severities of the phenotypic subtypes are mainly divided according to the ambulation status. We report a patient with the early-severe phenotype of UCMD who was diagnosed by the detection of novel recessive mutations in COL6A1.

Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology.
