OBJECTIVE: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). MATERIAL AND METHODS: Twenty-four single-root human mandibular premolars were selected and instrumented with nickel-titanium rotary file and the final file size was #40/06. They were then randomly allocated into 2 groups, and all samples were filled with single cone gutta-percha (#40/06) and one of the tested sealers (AH Plus and EndoSequence BC sealers)...

Diffuse Optical Tomography commonly neglects or assumes as insignificant the presence of optically clear regions in biological tissues, estimating their contribution as a small perturbation to light transport. The inaccuracy introduced by this practice is examined in detail in the context of a complete, based on realistic geometry, virtual fluorescence Diffuse Optical Tomography experiment where a mouse head is imaged in the presence of cerebral spinal fluid. Despite the small thickness of such layer, we point out that an error is introduced when neglecting it from the model with possibly reduction in the accuracy of the reconstruction and localization of the fluorescence distribution within the brain...

OBJECTIVE: To describe a case of partial nephrogenic diabetes insipidus in a burned patient after prolonged delivery of low inspired concentrations of sevoflurane via an Anesthetic Conserving Device. DATA SOURCES: Clinical observation. STUDY SELECTION: Case report. DATA EXTRACTION: Relevant clinical information. DATA SYNTHESIS: A 34-year-old man was admitted with burns covering 52% of his total body surface area...

INTRODUCTION AND OBJECTIVES: There is limited data on the serial morphological and functional assessment of paclitaxel-coated balloon treatment using coronary angiography, optical coherence tomography, and fractional flow reserve. METHODS: In this prospective, single-center observational study, patients with de novo lesions were treated with the paclitaxel-coated balloon. Serial angiographic, optical coherence tomography and fractional flow reserve measurements were performed before and after plain old balloon angioplasty, as well as at 9-month follow-up...

BACKGROUND: Biomechanical studies suggest that augmenting anterior fixation of the pelvic ring with posterior fixation increases stability. Prior clinical studies have assessed radiographic outcomes following plate fixation of the symphysis. However, to our knowledge, none have directly compared the radiographic and clinical outcomes of anterior plate fixation alone with the outcomes of such plate fixation with the addition of posterior percutaneous screw fixation in the treatment of a partially disrupted hemipelvis...

18F-fluoride positron emission tomography (PET) can identify subtle functional variation prior to the major structural change detectable by X-ray. This study aims to investigate the mechanobiological bone reaction around the abutment tooth and in the residual ridge, induced by insertion of removable partial denture (RPD) within two different groups of patients: patients without denture experience (Group 1) and patients with denture experience before (Group 2), using 18F-fluoride PET imaging technique. 18F-fluoride PET/computerised tomography (CT) scan was performed to examine the bone metabolic change in mandible before and after the RPD treatment...

BACKGROUND: Little is known about the additional prognostic value of computed tomography (CT) in addition to computed radiography in displaced intra-articular calcaneal fractures. Thepresent study was undertaken to examine and compare the final radiographic outcomes and the prevalence of treatment methods of displaced intra-articular calcaneal fractures in patients with preoperative computed radiography alone vs. a combination ofcomputed radiography and computed tomogra- phy. MATERIAL AND METHOD: Thirty-four patients with 38 displaced intra-articular calcaneal fractures were divided into two groups: a group that was evaluated with computed tomography and computed radiography (17 patients; 20 fractures) and a group that was evaluated with computed radiography alone (17 patients; 18 fractures)...

Trauma is the principal cause of young peo ple's death. Care should be appropriate to the severity of the injuries and involves a multidisciplinary team around the clock. In this article, we examine a protocol of care based on ATLS (Advanced Trauma Life Support) recom mendations, including advances in imaging technology, which have greatly increased quality care in our institu tion. The protocol is based on patient stability and on injury mechanisms. The challenge is to avoid wasting time in the definitive treatment of lesions...
