Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

The authors report clinical results of twenty-three traumatic thoracolumbar burst fractures treated by internal fixation with Kaneda device after anterior decompression during recent three years. Thoracolumbar injuries made up 28.9% of total spinal injuries and the burst fractures treated by anterior decompression and stabilization with Kaneda device constituted 19.0% of all spinal injuries. The burst fractures occurred most frequently at the age of twenties and thirties. The main causes of injury were fall and vehicle accident. Superior end-plate fracture type was most common according to the types of burst fracture. The first and the second lumbar vertebrae were frequently involved. No patient showed neurological deterioration after surgery. Conus medullaris lesions in burst fractures of the thoracolumbar junction have a high potentiality for functional recovery because the lesions are not due to discontinuity or severe crush injury but due to simple compression by bony fragments. The Kaneda device offered enough stability to enable early ambulation with good alignment and solid fusion.
Transthyretin의 Glutathione 자동산화 촉진작용
박종근,정신,김재휴,김수한,강삼석,이제혁,안봉환 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.8
When reduced glutathione(GSH) was incubated at neutral pH and at 37°, its concentration decreased slowly with formation of oxidized glutathione(GSSG). Autooxidation of GSH was accelerated by Cu^(2+) and Hg^(2+), but not by other common mono-, di-, and tri-valent cations. Transthyretin was found to stimulate autooxidation of GSH in the presence or absence of Cu^(2+) and Hg^(2+). EDTA inhibited perfectly the autooxidation of GSH regardless of the presence of transthyretin. The stimulating activity of transthyretin was maximal at pH 7.0, declining progressively with increase or decrease of pH from 7.0. Sulfhydryl-blocking agents such as p-hydroxymercuribenzoic acid and Nethylmaleimide markedly inhibited the stimulating activity of transthyretin. Transthyretin stimulated autooxidation of other sulfhydryl compounds such as clithiothreitol and cysteine. However, it did not show a significant effect on autooxidation of sulfhydryl group of egg albumin and eye lens proteins. And transthyretin did not cause any oxidative change to thyroxine(T₄), 3, 5, 3Ltri iodo thyronine(T₃) and 3, 3: 5~triiodothpnine(rT₃) bound to it in the presence of GSH and Cu^(2+). The above results suggest that transthyretin may play a role in regulation of oxidized status of sulfhydryl groups in blood plasma and cerebrospinal fluid
거대 청신경초종의 수술치료성적 : 수술전 안면신경전위의 예견 Preoperative Prediction of Facial Nerve Displacement by MRI
정신,김태선,김재휴,김수한,강삼석,이제혁 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.12
A total of 22 patients(13 males and 9 females : mean age 49 years) with large acoustic neurinoma who underwent the retrosigmoid transmeatal approach from May 1993 to May )995 at the Chonnam university Hospital was reviewed retrospectively. The authors investigated the surgical results and accuracy in predicting the direction of displaced facial nerve which was determined by preoperative magnetic resonance(MRI) findings. In all cases the preferred method was the suboccipital transmeatal approach. The direction of displacement of the facial nerve could be predicted by preoperative axial and coronal MRI scans and verified intraoperatively. Gross total removal was performed in 82%, the accuracy rate for facial nerve displacement was 77% and anatomical preservation was accomplished in 82.3% of the totally removed cases. During follow-up good functional outcomes were achieved in 91% and fair in 45%. The authors conclude that such good surgical results can be attributed to advances in microsurgical technique and intraoperative facial monitoring. In addition preoperative prediction of the direction of displaced facial nerves has significantly reduced the incidence of severe facial nerve weakness.
