BACKGROUND: Polymerase chain reaction(PCR) has brought an oppotunity for rapid detection of Mycobacterium leprae in clinical pecimens for the diagnosis of leprosy. Th DNA segment specific to M. leprae was detectable in a matteir of hours and DNA from one orgnisa appeared positive by PCR. However, the PCR tool has not been evaluated using elinical specimeriis from leprosy patients and controls. OBJECTIVE & METHODS: The primers amplifying 372bp segment of rebetitive sequence of M. leprae DNA were used in PCR. Skin biopsy specimens from 102 leprosy patient, and controls were examined for the presence of M. leprae by PCR and the results were aomared with microscopic and histopathologic findings. RESULTS: 1. As a result, of PCR after DNA preparation of M. leprae, six other mycobacteria, ten other bacteria, and skin from leprosy with five other skin biopsy tissues, 372bp DNA fragment was specifically amplified from M. leprae. 2. Dot blot, hybridization of PCR products showed that the 372bp DNA from skin biopsy specimens were derived from M. leprae. 3. As a result of PCR after DNA preparation of 10-fold diluted M. legrae from mouse footpad, PCR gave a positive result as low as one organism. 4. Of 87 specimens in which acid-fast bacilli were found under microcopic examinations 97% had positive PCR results. 5. Of 97 specimens which hadihistopathologic evidences of leprosy 95% had positive PCR results. 6. Of 15 specimens in which acid-fast bacilli were not found under n!icroscopic examinations 73% had positive PCR results. In three of five cases which had neither histopathologic nor microscopic evidences of leprosy had positive PCR results. CONCLUSION: PCR method amplifying 372bp fragment of repetitive seqi,ence was highly sensitive and specific in detecting M. leprae DNA in skin biopsy specimens, thus may be a useful tool as an additive diagnostic method, espcially for cases where microscopic antihystopathologic findings are not definite.

Operative reduction is not essential for mild to moderate spondylolisthesis, but some authors agree that reduction of spondylolisthesis is beneficial for widening of intervertebral canal and consequently for decompression of neural tissue even though the degree of slippage is grade I or II. In our institute, we sometimes reduced the slippage for these reasons. But at follow up study we would find redisplacement and the degree of it seemed to be associated with the kind of instruments. So we analyzed redisplacement rate according to the kind of instruments in 59 cases of spondylolisthesis that were followed more than one year. The conclusions were as follow; 1. There was no significant correlation between reduction and redisplacement rate with pathologic type, lesion site, age,iscectomy and clinical result at least in grade I or II spondylolisthesis (P>0.05). 2. The pedicle screw system was more useful in reduction and its maintenance than the Luque ring system (P<0.001). 3. Redisplacement was occurred mainly within 2 months after operation, 4. The cause of redisplacement after reduction seems to be associated with mechanical insecurity before consolidation of the grafted bone takes place.

Uncontrolled cerebrospinal fluid (CSF) leakage after transsphenoidal surgery (TSS) for pituitary adenoma can lead to meningitis. Intracranial mycotic pseudoaneurysm is a rare complication in central nervous system infection. Large single pseudoaneurysm is more uncommon. Most mycotic aneurysms occur due to endocarditis. The present patient had no heart problem and was infected by CSF leakage after transsphenoidal surgery. We present a case of large ruptured mycotic pseudoaneurysm as a complication of cerebral infection after TSS for pituitary macroadenoma.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.
