  Background: Ankle fractures, especially those resulting from external rotation mechanisms are associated with injury to the distal tibiofibular syndesmosis. Some authors have recommended performing CT scanning after open ankle surgery to evaluate the reduction of syndesmosis. In this current study, we aimed to investigate the sensitivity of plain radiography in diagnosing syndesmosis malreduc...

Open-domain question answering is a hot research topic in recent years. QA Track held by NIST has offered a new evaluation on this topic. However, its target is aimed at plain text collection only. This paper focuses on QA for heterogeneous data, including plain text, summaries, tabular data, and video programs. Discussion of what necessary adaptation could be done to deal with such kind of dat...

A 38-year-old man with pneumococcal meningitis, pneumocephalus, and CSF rhinorrhea was admitted to our hospital. The CSF rhinorrhea had no traumatic or iatrogenic etiology. The patient was treated with meropenem and recovered from meningitis. Axial plain CT showed pneumocephalus (figure 1, A and B), but no skull defects. Three-dimensional CT revealed defects of the posterior walls of the spheno...

The water distribution network is an important part of the plain environment improvement system. To make efficient use regional diversion source, scientifically distribute flow and improve carrying capacity Haishu Plain, river hydrodynamic model used in this paper to simulate intake location, reasonable quantity influence range transfer Plain. simulation results have high accuracy, which can pr...

How different this seems from the desolate and malaria-ridden country widely portrayed by nineteenthand early twentieth-century visitors in the region, before the modern agricultural revolution changed the face of the landscape. At another time I hope to deal at length with the matter of cultivation in the Emathian plain in antiquity. At present, however, it may be useful to attempt to understa...

BACKGROUND Bony metastases were occasionally the initial presentations of malignancy. Overlooking of bony changes on radiographs in cancer patients with non-specific clinical symptoms may lead to delayed diagnosis. CASE PRESENTATION We presented a 70-year-old male having hypercalcemia and diffuse osteoblastic bone metastases on routine plain films. Finally, prostate cancer was diagnosed with ...
