Clinical and radiological evaluation of 19 patients with injury to the ethmoid bones following cranio-facial trauma is presented. The correlation of ethmoid trauma and damage to neighbouring structures is discussed. Two cases with damage to the orbits are demonstrated. These findings indicate that orbital involvement is relatively infrequent in association with ethmoid cell trauma. However, when it does occur, severe complications, such as infection and loss of vision may result. Early evaluation by computed tomography is the key to accurate diagnosis and prevention of these complications. Computed tomography is of inestimable value in the detection of minute and subtle bone fragmentation and sequelae.

"The disappearing lens": failure of CT to image the lens in traumatic intumescent cataract.

The CT scans of three patients whose eyes were lacerated by trauma failed to demonstrate the lens. A slit-lamp examination of those eyes clearly indicated that the lenses were present behind the iris but that they were swollen and opaque (intumescent cataract). Apparently, a shift of water into the injured lens had reduced the expected hyperdense CT image of the lens to a level that it was no longer discernible.

Serotypes of Ureaplasma urealyticum isolated from patients with nongonococcal urethritis and gonorrhea and from asymptomatic urethral carriers.

Ureaplasma urealyticum strains isolated from urethral specimens of 112 patients with nongonococcal urethritis, 17 with gonorrhea, and 33 asymptomatic carriers (controls) were tested by the growth-inhibition test with standard ureaplasma antisera (serotypes 1-8). Cases with more than one serotype (two to four types) were encountered in 36.6% of patients with nongonococcal urethritis, 29.4% of those with gonorrhea, and 21.2% of controls. The most frequently recovered serotypes were type 4 from patients with nongonococcal urethritis (57.1%) and type 2 from patients with gonorrhea and controls (35.2% and 36.3%, respectively). The difference in frequency of serotype 4 between patients with nongonococcal urethritis and controls was statistically significant (P less than .001). An additional serotyping with types 9 and 10 antisera of the nontypable strains from patients with nongonococcal urethritis and controls (17.8% and 21.2%, respectively) revealed three type-9 strains. The results show a need for utilization of serotyping of U. urealyticum in studies of the epidemiology and transmissibility of genital infections with U. urealyticum.
