Penetrating cardiac injury caused by nail gun is an uncommon life-threatening condition characterized by a rapidly severe hemodynamic status compromise. We report non-contrast-enhanced CT findings of a right ventricle myocardium injury leading to a fluid collection in the pericardial space with the same attenuation as blood. The CT findings well depicted the pathological feature of a significant cardiac injury and may be helpful for the surgical management. [ J Trauma Inj 2017; 30: 21-23 ]
Large scale studies of temporal reduction are of interest to obtain linguistic knowledge and this understanding can potentially help improve speech technologies. Automatic speech recognition (ASR) supports the processing of very large corpora and can be used to enrich linguistic studies with models of speech production and perception grounded on observed commonly used pronunciations. In return, ASR can benefit from the linguistic findings by including pronunciation variants that reflect the linguistic variability. This study focuses on two temporal reduction phenomena in Peninsular and Latin American varieties of Spanish: lenition of intervocalic voiced stops V/bdg/V and coda-s. First, the two phenomena are investigated via a study of transcription errors produced by a speech recognition system designed for Peninsular Spanish which can be potentially attributed to lenition. In a second step, automatic forced alignment experiments are conducted using specific pronunciation variants with and without lenition to measure the extent of the phenomenon as a function of geographical and stylistic repartition. The results show that the distribution of pronunciation variants across Peninsular and Latin American Spanish varieties is consistent with trends depicted by classical linguistic studies. The speaking style appears to be the main factor affecting the +/-lenition variation. The findings also suggest that including such variants in ASR system's lexicon may improve performance when processing multiple Spanish varieties.
Solitary plasmacytoma and extramedullary plasmocytoma are tumors of malignant character composed of plasma cells, with a mean age of onset at 60 years. They can appear anywhere where the reticuloendothelial system is present. Usually these tumors lead to the development of multiple myeloma in a period of time ranging from 3 to 5 years. We present a rare case handled in our neurosurgery service associated with an unusually long period of evolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
