The diagnostic value of the DNA polymerase chain reaction for the detection of M. tuberculosis in tuberculous meningitis uas established by using cerebrospinal fluids obtained from 7 bacteriologically confirmed patients (Group IA), 17 clinically diagnosed patients (Group IB), 21 patients with other bacterial or viral meningitis (Group IIA) and two norrnal persons (Group IIB) The PCR was perforrned with P1 and P2 primer set which directed against the 123bp segment of IS5110. A repetitive sequence of M. tuberculosis chromosome. The sensitivity and specificity of the PCR for the detection of M. tuberculosis was evaluated by using DNAs purified from cultured M tuberculosis and M intracellulare . The detection limit by the PCR amplication with Pl and P2 primer was lfg of DNA for M. tuberculosis and lpg for M. intracellulare indicating that the PCR was very sensitive for M. tubererculosis DNA detection; although weakly cross-reactive with DNA of M. tuberculosis. Of the 7 cerebrospinnal fluids from bacterologically proven tuberculous meningitis patients (Group IA), 7 samples were all positive by PCR (10Q%). 15 sarnples of 17 the AFB smear-negative and culture-negative samples from tuberculous meningitis patients (Group IB) were positive by PCR (88.2%) and 2 of 2l sanples from other meningitis patients (Group IIA) showed positive reaction (9.5%). There were no sarnples whick showed positive reaction by PCR among 2 sarnples from normal persons (Group IIB). This results indicated that the PCR using P1 and P2 primer set was useful for the early diagosis of tuberculous meningitis.

Wall-eyed monocular internuclear ophthalmoplegia (WEMINO) with contraversive ocular tilt reaction has not been previously reported. A 71-year-old woman suddenly developed blurred vision. Examination revealed left internuclear ophthalmoplegia, left exotropia, right hypotropia, and rightward head tilt. Magnetic resonance imaging showed a tiny infarction at the area of the left medial longitudinal fasciculus in the upper pons. WEMINO with contraversive ocular tilt reaction may be caused by a paramedian pontine tegmental infarction that selectively involves the medial longitudinal fasciculus.

BACKGROUND: The purpose of this study was to assess the efficacy and safety of entacapone, a catechol-O-methyltransferase (COMT) inhibitor in Parkinson's disease (PD) patients with wearing-off phenomenon. METHODS: A total of 197 PD patients were included in this 2-month multi-center, randomized, placebo-controlled, double blind, parallel-group study. After a 2-week screening period, each patient was randomly allocated to receive either entacapone (n=98) or placebo (n=99) as an adjunct to levodopa. The efficacy was evaluated with the changes of "on" and "off" time percentage while awake, the reduction of the levodopa dose, Unified Parkinson's Disease Rating Scale (UPDRS), and the clinical global impression (CGI) by the examiner. RESULTS: The percentage of "on" time increased by 9.4 +/- 18.0% in the entacapone group, 7.4 +/- 15.6% in the placebo group. The percentage of "off" time was reduced by 8.6 +/- 16.9% in the entacapone group, 6.6 +/- 18.2% in the placebo group. These parameters did not show a statistical significance between the two groups. However, the levodopa dose was significantly reduced in the entacapone group (51.6 +/- 154.5 mg/day) compared with the placebo group (0.7 +/- 130.0 mg/day) (p=0.009). The total and motor scores of the UPDRS were significantly decreased in the entacapone group (p=0.039, p=0.017, respectively). The most common adverse drug reactions in the entacapone group were urine discoloration (22%), dyskinesia (13%), dizziness (7%). CONCLUSIONS: Entacapone was a safe and well-tolerated drug. Although the changes of "on" and "off" time were not significant, entacapone showed an overall significant beneficial effect in the PD patients with wearing-off phenomenon.
