  • Acute Transverse Myelitis is a syndrome, not a disease, in which acute inflammation affects gray and white matter in one or more adjacent thoracic segments. Almost all patients will develope ascending weakness and numbness of feet and leg, difficulty voiding, urinary retention, and loss of bowel control. We concluded this case to MAMOK( 마목) due to Qi ascent, Qi deficiency, Qi stoppage(상기, 기허, 기체). So we used herbal medication, acupuncture, and homeopuncture according to oriental medical theory. Weakness and numbness of feet and leg, difficulty voiding, urinary retention, and loss of bowel control are reduced. Herbal medication, acupuncture, and homeopuncture helped the care of this syndrome and further study will be investigated in oriental medicine for this syndrome.

  • Glutaric aciduria type 1 is an inborn error of lysine, hydroxylysine, and tryptophan metabolism caused by deficiency of glutaryl-coenzyme A dehydrogenase. The disease often appears in infancy with encephalopathy episode that results in acute basal ganglia and white matter degeneration. The majority of patients develop a dystonic-dyskinetic syndrome. This reports 6year-old boy who had been done previous gastrostomy due to swallowing difficulty underwent bilateral pallidotomy with intraoperative electromyography[EMG] monitoring for disabling dystonia. Intraoperative EMG was used to assess stimulation thresholds required for capsular responses and muscle tone. Surface EMG electrodes were placed on the face and cricopharyngeal muscles. Exact target were directly modified according to MRI-visualized anatomy. EMG response was consistently seen prior to visual observation of muscle activity. The surgery improved dystonic symptoms without swallowing difficulty.

  • Metronidazole-induced encephalopathy is a very rare complication of the long standing use of metronidazole. The encephalopathy is bilateral and symmetric in nature. We report on the magnetic resonance imaging (MRI) and clinical course of metronidazole-induced encephalopathy in a 60-year-old female with a persistent anaerobic brain abscess after draining of the abscess. After 3 months of metronidazole administration, the patient complained of dysarthria, tingling sense of all extremities, and left hemiparesis. MRI revealed symmetric hyperintensity lesions in medulla, pons, dentate nuclei of cerebellum, and splenium of corpus callosum, all of which represent typical findings of metronidazole-induced encephalopathy. In addition, asymmetric lesions in midbrain, thalamus, putamen and cerebral subcortical white matter were noted. The patient recovered after discontinuation of metronidazole and the remaining abscess was successfully treated with meropenem and levofloxacine.

  • Ependymal cysts are neuroepithelial cysts, typically found in the central white matter of the temporoparietal and frontal lobes. Clinical symptoms usually result from neurological deficits referable to these regions, from seizures, and chronic headaches associated with increased intracranial pressure. We describe here a case of ependymal cyst on the right fronto-parietal lobe, presenting with tremor and weakness. The cyst was resected surgically and presurgical neurological abnormalities were improved. An exploratory surgery with establishment of an adequate route of drainage and histological examination of the cyst wall are mandatory in the management of patients with a progressive and symptomatic intraparenchymal cyst.

  • 의료 영상 처리 기술은 질병의 진단 및 치료를 위한 계획이나 방법을 결정하는데 있어 매우 중요한 역할을 하고 있으며 의료 영상 시스템과 같은 활용 분야에서는 질병이 있는 환자의 자동 진단을 위한 연구도 활발하게 이루어지고 있다. 여기서는 뇌 MR영상에서의 질병을 자동 진단할 수 있는 방법에 관한 연구를 한다. 뇌 MR영상에서의 질병 진단을 위한 단계로서 필수적으로 이루어져야 하는 단계가 비정상 영역의 추출 단계이다. 이 논문에서는 뇌의 질병 진단에 사용할 수 있는 자료를 제공하기 위한 전처리 단계로서 질병이 있는 환자의 뇌 영상에서 비정상적인 영역 추출 방법을 제안한다. 일반적으로 비정상적인 영역의 명암간 분포는 회백질 영역의 분포와 유사하나 두께 차이로서 구분이 가능하다. 여기서는 이 정보를 활용하여 정상인의 뇌영상에 대해서 회백질의 평균 두께 분포를 구하여 테스트로 입력되어지는 영상에서 회백질의 평균 두께 이상의 영역만을 남김으로서 질병이 있는 환자의 뇌 영상에서 비정상적인 영역을 추출할 수 있음을 보인다. 또한 추출되어진 비정상 영역에 대해서 진단에 필요한 인자를 자동으로 측정하였고 뇌경색, 뇌종양 환자를 포함한 63명의 뇌 MR 영상 시리즈에 대해서 실험하여 비교적 정확한 추출결과를 유도할 수 있었음을 확인하였다.

  • Development of a noninvasive intensive care system calls for the use of evoked potentials (EPs), as a means of diagnosing traumatic head-injured patients. The experiment entails surgically plating two subarachnoid bolts and a subdural balloon through the skull to simulate a subdural hematoma. Using various levels of intracranial pressure (ICP) and/or different sizes of balloons, auditory evoked potentials (AEPs) were recorded from a rabbit. Six positive peat latencies ($P_1-P_6$) and five negative peak latencies ($N_1-N_5$) were extracted from an averaged AEP waveform. Multiple regression analyses were performed for determining a relationship between the ICP and AEP peak latencies. The results indicate that a major correlation of changes on AEP peak latencies is due to mechanical forcer of a mass (inflated balloon simulating a hematoma) in the distortion of the brain matter rather than increased ICP.

  • A dead marten(Martes melampus) showing cough, ataxia and convulsion of hind limb followed by seizures, was submitted for diagnosis to the Pathology Division of the National Veterinary Research and Quarantine Service. In the gross lesions, lung was congested and consolidated and meningeal blood vessels were mildly congested. Histopathologic findings were diffuse interstitial pneumonia and nonsuppurative meningoencephalitis with malacia of cerebral and cerebellar white matter. Eosinophilic inclusion bodies were observed in neurons and astrocytes and oligodendroglial cells of brain and transitional epithelium of kidney. Using FA test and PCR method, specific antigens of canine distemper virus were demonstrated in the brain.

  • We present here the case of a 13-year-old male patient with Alexander's disease who underwent surgical correction of a femur fracture. Alexander's disease is a rare and fatal disorder that affects the white matter in the brain and it causes developmental delay, psychomotor regression, spasticity, megaloencephaly and seizure. The patient had the possibility of a seizure attack during the perioperative period. We discuss the anesthetic management of a patient with Alexander's disease and we review the relevant literature.
