A rare case of bilateral bronchial foreign body.

We present the case of a 7-year-old male patient with bilateral bronchial cocklebur fruit aspiration, which he sustained while playing. The patient presented with a triad of cough, wheezing, and decreased breath sounds (decreased in the right lung and absent in the left). These symptoms led to a diagnosis of bilateral bronchial foreign body, which was confirmed by computed tomography three-dimensional reconstruction of the bronchial tree.

Benefits of spatial hearing to speech recognition in young people with normal hearing.

Background: Many factors interfering with a listener attempting to grasp speech in noisy environments. The spatial hearing by which speech and noise can be spatially separated may play a crucial role in speech recognition in the presence of competing noise. This study aimed to assess whether, and to what degree, spatial hearing benefit speech recognition in young normal-hearing participants in both quiet and noisy environments.

[Method of measuring sound localization for 4-year-old children on the horizontal plane.].

Objective: To investigate the effective way to test 4-year-old children's ability of sound localization in the horizontal plane.

Methods: Using minimum audible angle (MAA) measure procedure on the basis of conditioned play audiometry, sound localization test was conducted for 4-year-old children at 0 degrees , +/- 45 degrees , +/- 90 degrees , +/- 135 degrees and 180 degrees standard positions in the horizontal plane.

Results: The outcome of sound localization test for 4-year-old children separately were: MAA (0 degrees ) = (3.

Arsenic trioxide inhibits metastatic potential of mouse hepatoma H22 cells in vitro and in vivo.

Background: It has been pointed out that only low-dose arsenic trioxide (ATO) presents therapeutic benefits outweighing the toxic side effects. Low-dose ATO can effectively alleviate acute promyelocytic leukemia (APL). However, it is quite challenging in treating solid tumors.
