The optic nerve is part of the central nervous system, and a rise in intracranial pressure (ICP) can directly affect the perioptic nerve space, leading to an increase in nerve diameter. Transorbital sonography is a safe and easy-to-perform method to measure optic nerve diameter for rapid diagnosis of increased ICP. ⋯ Optic nerve diameter, measured by transorbital sonography, was significantly greater in pediatric patients with increased ICP compared with a control group. Transorbital sonography can be used to identify pediatric patients with raised ICP.

To evaluate the role of sonographically guided small-bore chest catheters and sonographically based monitoring of fluid evacuation in rapid sclerotherapy of malignant pleural effusions. ⋯ Rapid pleurodesis can be accomplished within 24 to 48 hours, with good short- and long-term responses. Thoracic sonography plays a pivotal role. It guides placement of the pleural catheter and is valuable in the monitoring of fluid evacuation for determining the right time for sclerosing agent administration and in the detection and treatment of loculations or residual pleural fluid due to tube malfunctioning.

Comparative Study
Evaluation of differences between observers and automatic-manual measurements in calculation of Doppler parameters.
We aimed to search for differences between observers and automatic and manual measurements in calculations of Doppler parameters. ⋯ Although our study was performed on healthy subjects, our results showed that, in most cases, readers and the automatic approach disagreed on evaluation of Doppler parameters. This may be important in preventing false diagnoses in cases with Doppler values close to upper limits and may necessitate establishment of new limits for each method.
