Evaluation of Stomach Neoplasms With 3-Dimensional Computed Tomography: Focus on the Potential Role of Cinematic Rendering

Evaluation of stomach neoplasms by traditional 3-dimensional (3D) computed tomography methods such as volume rendering and maximum-intensity projection plays an important role in lesion detection and characterization, preoperative planning, staging, and follow-up. Recently, a new 3D visualization method has become available known as cinematic rendering (CR). This novel technique makes use of a complex global lighting model to impart photorealistic levels of detail to 3D images. Although this new technique has yet to be systematically studied for the evaluation of stomach neoplasms, its intrinsic ability to create realistic shadowing effects to enhance understanding of the 3D relative locations of anatomic structures and to enhance detail and texture may prove valuable for a variety of applications. In this article, we demonstrate the CR appearance of multiple different gastric neoplasms, describe potential advantages of CR, and suggest future research directions.

CONCLUSION: The current study showed that man gender, diabetes and hypertension were the greatest risk factors for PAD. We conclude that man patients with diabetes and/or hypertension should be put under serious consideration for routine CTA examination when under evaluation for LSS and intermittent claudication.

CONCLUSION: The prodromal symptoms of COVID-19 were mild and most patients did not have limitations of daily activity. Viral shedding from URT was high from the prodromal phase. Radiological pneumonia was common from the early days of illness, but it was frequently not evident in simple CXR. These findings could be plausible explanations for the easy and rapid spread of SARS-CoV-2 in the community. PMID: 32242348 [PubMed - in process]

CONCLUSION: The absence of vasospasm in the first DSA performed in patients with SAH and negative tomographic angiography could be a useful criterion for establishing an optimal follow-up protocol in these patients, without exposing them to unnecessary risks and radiation.

CONCLUSION: Penetrating trauma in children and adolescents is associated with significant mortality and morbidity. There are similarities with the management of these injuries in adults, but further work is required to ensure that paediatric management algorithms are evidence based.

Authors: Dahal S, Budoff MJ Abstract The results of the ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approach) trial were presented at the American Heart Association Scientific Sessions in November, 2019 in Philadelphia, Pennsylvania, and recently published on March 30, 2020 in the New England Journal of Medicine. After an average follow-up of 3.5 years, invasive therapy did not reduce the major adverse cardiac event (MACE) rate compared with optimal medical therapy (OMT) in patients with stable ischemic heart disease. However, the ISCHEMIA trial results might stem fro...

Authors: Campioni I, Cacciotti I, Gupta N Abstract Additive manufacturing (AM) presents unique opportunities for medical applications and in particular in maxillofacial surgery for developing patient specific implants. The quality assessment of additive manufactured products is an essential aspect for the real introduction in health services. In this framework, the purpose of the present study is to investigate the possibility of developing prototypes of mandibular plates as preoperative surgical planning models, by verification of design, analysis of internal structure integrity and evaluation of the effects of va...

Authors: Fischer VE, Boulter JH, Bell RS, Ikeda DS Abstract Severe traumatic brain injury has historically been a non-survivable injury. Recent advances in neurosurgical care, however, have demonstrated that these patients not only can survive, but they also can recover functionally when they undergo appropriate cerebral decompression within hours of injury. At the present, general surgeons are deployed further forward than neurosurgeons (Role 2 compared to Role 3) and have been provided with guidelines that stipulate conditions where they may have to perform decompressive craniectomies. Unfortunately, Role 2 medic...

Abstract In Brazil, rabies occurs mainly within an urban cycle, in which dogs and bats are reservoirs. This paper aims to report the occurrence of rabies in Callithrix sp. in Niter ói, Rio de Janeiro, Brazil. In June 2019 a hybrid specimen was referred for diagnosis. The Direct Fluorescent Antibody, Mouse Inoculation, and Polymerase Chain Reaction tests were positive. A phylogenetic analysis was compatible with antigenic variant 3, characteristic of Desmodus rotundus. New stu dies should be undertaken to elucidate the real role of callitrichids in the urban rabies cycle.
