Discovery from a lateral oblique radiograph

Lateral cephalometric radiograph versus lateral nasopharyngeal radiograph for quantitative evaluation of nasopharyngeal airway space

OBJECTIVE This study compared lateral radiographs of the nasopharynx (LN) and lateral cephalometric radiographs (LC) used to assess nasopharyngeal airway space in children. MATERIAL AND METHODS One examiner measured the nasopharyngeal space of 15 oral breathing patients aged between 5 and 11 years old by using LN and LC. Both assessments were made twice with a 15-day interval in between. Inte...

Lateral and oblique gene transfer.

Sequence information from complete genomes, and from multiple loci of strains within species, is transforming the way that we investigate the evolution of bacteria. Such large-scale assessments of bacterial genomes have provided evidence of extensive gene transfer and exchange. Except in rare cases, these two processes do not seem to be coupled: certain species, such as Escherichia coli, underg...

Biomechanics of Oblique Lateral Impacts

A majority of laboratory-driven side impact injury assessments are made using post mortem human subjects (PMHS) under the pure 90-degree lateral mode. Because real-world injuries occur under pure and oblique modes, this study was designed to evaluate injury metrics and injury mechanisms with PMHS under the latter vector. Anthropometrical data were obtained and functional x-rays were taken. Spec...

Appearance of the weight-bearing lateral radiograph in retrocalcaneal bursitis

BACKGROUND AND PURPOSE A retrocalcaneal bursitis is caused by repetitive impingement of the bursa between the Achilles tendon and the posterosuperior calcaneus. The bursa is situated in the posteroinferior corner of Kager's triangle (retrocalcaneal recess), which is a radiolucency with sharp borders on the lateral radiograph of the ankle. If there is inflammation, the fluid-filled bursa is less...
