Cerebral hyperemia during recovery from general anesthesia in neurosurgical patients.

Unlabelled: Changes in the cerebral circulation during recovery from neurosurgical anesthesia are poorly understood. We used transcranial Doppler to compare cerebral blood flow velocity changes (Vmca) during recovery after anesthesia. In the first part of the study, 30 patients were randomized to propofol- or isoflurane-based anesthesia.

Male urethritis with and without discharge: a clinical and microbiological study.

Background: The definition of male urethritis in the absence of urethral discharge has not been well established. The sensitivity of urethral swabs and first-catch urine is controversial.

Goal Of This Study: To correlate clinical data (discharge or not), urethral swabs, and first-catch urine examinations with the microorganisms found within the urethra in a cohort of men attending the sexually transmitted disease clinic of Hôpital Saint Louis (Paris) for treatment of urethral symptoms with or without discharge.

[Asymptomatic carriage of Chlamydia trachomatis in men consulting for condylomata acuminata].

A search for Chlamydia trachomatis by cell culture was carried out in the urethra of 82 male patients consulting for condyloma acuminata at the Clinical and Biological Centre for Sexually Transmissible Diseases of the Saint-Louis hospital, Paris. Three patients had discreet urethral signs, but none had urethral discharge. Cell culture was positive for C.

Proton radiation damage in optical filter glass.

Samples of Schott BG-39 and Hoya CM-500 blue-green filter glass were subjected to proton radiation to determine their acceptability for spaceflight. Initial testing done with 2.7 MeV protons showed negligible change in optical transmittance with doses as high as 5.
