Postoperative endophthalmitis caused by Sphingomonas paucimobilis.
ABSTRACT We present a case in which a new organism, Sphingomonas paucimobilis, caused endophthalmitis after phacoemulsification in a 73-year-old woman. The case shows a recurrent acute endophthalmitis with complete resolution only after vitrectomy. This organism has not been described as a cause of endophthalmitis and was resistant to initial medical management. We also describe an interaction between this organism and a co-infective organism that may account for the unusual clinical course.

ABSTRACT: A three-year-old male patient was brought to our clinic by his family with the complaint of a non-healing wound with discharge on his forehead and the nasal region. He had a history of a fall one-year ago. The patient had recurrent complaints of swelling and hyperemia following this trauma. He had undergone an operation with the pre-diagnosis of foreign body in soft tissue six months ago. However, no foreign body had been detected and the inflamed tissue had been excised and closed again. The swelling and purulent discharge in the region between nose and eye continued after this surgery. The patient underwent an operation and a circular defect 0.5 cm in diameter was detected on the dorsum of the nasal bone and a fistula tract was found to have developed between this defect and the skin between the nose and the eye. A subcutaneous forehead flap without skin tissue was removed including the periosteum from the left part of forehead after excision of the fistula tract. The flap was transferred to the nasal dorsum and the component of the forehead flap including the periosteum was used for reconstruction of the nasal mucosa. The wound healed without any problems and no fistula or infection developed again during the six-month follow-up.Kulak burun bogaz ihtisas dergisi: KBB = Journal of ear, nose, and throat 21(1):46-8.

ABSTRACT: Timing jitter measurements have been conducted on the ORION photoinjector laser oscillator pulse train output with respect to a ultra low noise crystal rf oscillator running at 79 1/3 MHz, the 36th harmonic of S-Band. The ORION laser oscillator subsystem consists of a Spectra-Physics Tsunami ultra-fast tunable (750 - 850 nm) laser pumped by a diode pumped Spectra-Physics Millennia VsP 5 W. Overall laser oscillator subsystem performance will be presented. These measurements consist of the laser oscillator generated noise and transfer function from the RF reference input of the laser to an external photodiode RF output. Timing jitter measurements of less than 500 fsec have been attained with the laser oscillator tuned to 800 nm.Particle Accelerator Conference, 2003. PAC 2003. Proceedings of the; 06/2003
Conference Paper: Beamline design for particle production experiment, E907, at FNAL[Show abstract] [Hide abstract]
ABSTRACT: Experiment 907 at Fermilab will be conducted in the Meson Center beam enclosure. The purpose of this experiment is to measure cross sections for hadron production from nuclear interactions using pions, kaons and proton beams in the momentum range from 5 to 120 GeV/c. Light to heavy targets will be used to study the scaling laws of hadronic fragmentation and light meson and baryon spectroscopy. Design aspects for the experiment's beamline are presented. The lattice, in particular the secondary beamline design, the primary target, and the collimation system are covered.Particle Accelerator Conference, 2003. PAC 2003. Proceedings of the; 06/2003
