Evaluation of mandibular volume using cone-beam computed tomography and correlation with cephalometric values.
Evaluation of mandibular volume using cone-beam computed tomography and correlation with cephalometric values. Angle Orthod. 2013 Aug 28; Authors: Katayama K, Yamaguchi T, Sugiura M, Haga S, Maki K Abstract Abstract Objective: To investigate the association between maxillofacial morphology and mandibular bone volume in patients with skeletal malocclusion. Materials and Methods: Subjects were 118 adult Japanese (58 males and 60 females). Skeletal malocclusion was classified, based on cephalometric analysis, into skeletal Classes I (-1° ≤ ANB
ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.
Polydioxanone (PPDO) is a resorbable polymer that has been shown to be effective resorbable inferior vena cava filters (IVCF) in preventing pulmonary embolism (PE). However, PPDO is radiolucent with no intrinsic capability for radiographic visualization. Here, we synthesized bismuth nanoparticles (BiNPs) and infused unto PPDO, making it visible by x-ray and computed tomography (CT). This enhanced radiopacity will allow placement accuracy during device implantation and continuous monitoring of the structural integrity of the device to check for fracture or device failure post implantation.
To explore whether it is necessary to obtain chest radiographs post CT-guided lung biopsy with gelatinous foam slurry needle track embolization
To quantify the frequency and accuracy of inferior vena cava filter reporting practices on plain radiography and computed tomography examinations with attention to retrievability and device brand. Improved reporting may encourage appropriate anticoagulation or facilitate filter retrieval.
This study aimed to investigate a series of patients diagnosed with LTBI during screening before immunosuppressive therapy, describing how the use of diagnostic tests and treatment evolved over time. This retrospective cohort study included all individuals diagnosed with LTBI during screening before intended immunosuppressive therapy in a tertiary care hospital between January 2000 and December 2017. Evidence for LTBI, including history, tuberculin skin test (TST), QuantiFERON (QFT) result and suggestive lesions on chest radiography (CXR), and CT scan if available, was analyzed. The study included 295 individuals with LTBI...
AbstractMandibular fractures are among the most common maxillofacial fractures observed in emergency rooms and are mainly caused by road accidents. The clinical features of mandibular fractures include malocclusion and loss of mandibular function. Panoramic radiography is usually limited to isolated lesions, whereas computed tomography is the tool of choice for all other facial traumatic events. No reference standard classification system for the different types of mandibular fractures is defined. Therapeutic options include a conservative approach or surgical treatment based on the anatomic area and the severity of fractu...
Conclusions3-dimensional printing technique-assisted arthroscopic bone graft and fixation of scaphoid nonunion constitute an effective and accurate clinical treatment option.
ConclusionsThe novel success scale for evaluating alveolar cleft repair using CBCT takes into consideration all dimensions of the bony bridge. Future application is necessary for validation of its potential value.

ConclusionThis is the first study to compare PEMF and CMF bone growth stimulators in patients with degenerative pathologies who underwent thoracolumbar spinal fusions. Overall, the addition of these bone growth stimulators does not improve fusion outcomes, although CMF appears superior to PEMF.
