Publication date: Available online 17 December 2018Source: Saudi Journal of OphthalmologyAuthor(s): Maria Araújo, Tânia Borges, Yolanda Mahia, Vânia Lages, António PereiraAbstractThe solitary fibrous tumor (STF) is a rare spindle cell tumor that most often occurs in the pleura, mediastinum and other serosal sites, but it can be found anywhere.[1] The authors present a case report of a 35-year-old male who was submitted to an eventless left external dacryocystorhinostomy (DCR) due to epiphora. During the surgery no tumors or anomalous tissues were visualized. Five months later the patient presented...

Cancers, Vol. 10, Pages 519: EphA3 Pay-Loaded Antibody Therapeutics for the Treatment of Glioblastoma
In this study, we assessed the efficacy of EphA3 antibody drug conjugate (ADC) and radioimmunotherapy (RIT) approaches using orthotopic animal xenograft models. Brain uptake studies, using positron emission tomography/computed tomography (PET/CT) imaging, show EphA3 antibodies are effectively delivered across the blood-tumour barrier and accumulate at the tumour site with no observed normal brain reactivity. A robust anti-tumour response, with no toxicity, was observed using EphA3, ADC, and RIT approaches, leading to a significant increase in overall survival. Our current research provides evidence that GBM patients may be...

Low dose CT scan in stone detection for stone treatment follow up: is there a relation between stone composition and radiation delivery? Study on a porcine-kidney model.
CONCLUSIONS: Ultra-low-dose CT has a good detection rate for all kinds of stone, even when the fragment size is small. Only small uric acid fragments need higher energy settings in order to be detected. When the stone composition is known after surgery for urolithiasis, the most appropriate CT scan setting could be suggested by the urologist during their follow-up.

How to Best Predict Fragility Fractures: An Update and Systematic Review.
Authors: Allon R, Levy Y, Lavi I, Kramer A, Barzilai M, Wollstein R Abstract BACKGROUND: Because fragility fractures have an enormous impact on the practice of medicine and global health systems, effective screening is imperative. Currently, dual-energy X-ray absorptiometry (DXA), which has limited ability to predict fractures, is being used. We evaluated the current literature for a method that may constitute a better screening method to predict fragility fractures. A systematic review of the literature was conducted on computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound to evaluate screenin...

Sensors, Vol. 18, Pages 4458: Development of Limited-Angle Iterative Reconstruction Algorithms with Context Encoder-Based Sinogram Completion for Micro-CT Applications
This study describes the construction of different scan acquisition protocols for micro-CT system applications. Fully-sampled Feldkamp (FDK)-reconstructed images were used as references for comparison to assess the image quality produced by these tested protocols. The insufficient portions of a sinogram were inpainted by applying a context encoder (CE), a type of generative adversarial network, to the LAIR process. The context image was passed through an encoder to identify features that were connected to the decoder using a channel-wise fully-connected layer.

Gubernaculum dentis in a transmigrating canine: case report and literature review
DiscussionHistologically, GD consists of a fibrous band running in the bony channel that connects the pericoronal follicular tissue of the successional tooth with the overlying gingiva. Typically, GD opens on the alveolar bone crest behind the deciduous teeth. Radiographically, GD appears as a corticated tract of low density, contiguous with the dental follicle of an unerupted tooth on CBCT.3 It would be difficult to visualize the very thin and round radiolucent structures with a diameter of only 1 to 3 mm on 2-dimensional radiographs. In addition, the structure lies in the spongy bone of the maxilla and the mandible. Ther...

ConclusionsLocalized swelling, with or without pain, is the characteristic feature of osteosarcoma. A purely osteolytic lesion demonstrates a radiolucency with “moth-eaten” or irregular borders that seem to infiltrate into the surrounding bone. Early-stage osteosarcoma of the jaw can also appear as symmetric widening of the PDL space. Therefore, when there is suspicion, biopsy should be performed to rule out malignancy.

ConclusionsThe 4 hallmark radiographic findings for an aberrant ICA are an enlarged inferior tympanic canaliculus (ITC), an enhancing hypotympanic mass, an absent vertical segment of the ICA, and dehiscence of the cortex covering the tympanic portion of the ICA.4 Because of the lack of soft tissue/vascular contrast on a CBCT image, only an enlarged ITC and dehiscence of the cortex were seen in this study. Aberrant ICAs are known to cause tinnitus, which can mimic symptoms of a temporomandibular disorder (TMD).5 Because the patient was lost to follow-up, these findings could not be correlated clinically.

Incidental findings on cbct and classification according to their significance
In the future, 3-dimensional diagnostic imaging will certainly be the preferred imaging method in dentistry, with cone beam computed tomography (CBCT) featuring prominently in the management of many cases. Nevertheless, increased information that advanced imaging techniques can result in increased amounts of findings that are unrelated to the reason the examination was conducted. The prevalence rate of these occult entities on CBCT varies widely among reported studies and may exceed 50%, depending mainly on demographic factors and field of view (FOV).
