ABSTRACT Neurobrucellosis is a rare form of localized brucellosis usually with no systemic manifestations. We report a rare case of brucellosis presenting as meningoencephalitis associated with hydrocephalus. This patient had a lymphocytic predominant CSF and was initially treated with empirical anti tubercular therapy and steroids. A week later, when his CSF culture grew Brucella species, the treatment was changed to a combination of streptomycin, doxycycline and rifampicin and the patient improved with this therapy. This case illustrates the need to consider neurobrucellosis as a close differential diagnosis of neurotuberculosis in endemic areas when the patient presents with meningo encephalitis with lymphocytic CSF

    ABSTRACT: A new designed Autonomous Underwater Vehicle r2D4 for operation to 4,000 meters was built for the purpose of seafloor mapping on the oceanic ridge having hydrothermal activity in July 2003. An expanded interferometry sonar with operating frequencies of 100 kHz was installed on the AUV for high resolve bathymetry mapping, not to mention the backscatter imaging. In effect, the interferometry sonar is simply composed of three hydrophones, which are arranged at intervals of three and thirteen wavelengths in the L-shape at each side, in addition, to a side scanning sonar Klein System 2000 with operating frequencies of 100 kHZ and 500 kHz. It explains features of low cost and low power consumption. An initial survey test of the AUV was carried out up to 500 meters deep off Ryotsu port of Sado Island in July 2003. In advance of the sea test of the AUV, a test of the interferometry sonar with the barge had been carried out. L-shape array of hydrophones enables us to make a phase difference measurement successfully with high resolution. It follows that a detailed swath bathymetry was brought about. Consequently, a seafloor mapping was carried out to reveal the detail topography on the top of Kuroshima knoll in the vicinity of Okinawa islands in December 2003. The AUV is installed with the PHotonic Inertial Navigation System (PHINS), which provides inertial navigation and motion measurements of the AUV. Furthermore, since the AUV is able to move underwater very stably along planed courses, it is a proper platform in materializing the synthetic aperture of the side scanning transducers. We have been devoting ourselves to process the observation data. As a result, the synthetic aperture technique was very useful for the improvement of the seafloor bathymetry mapping as expected.
