Its flexibility and modularity allows additional data sources and parameters, such as elastography or degrees of fibrosis, to be integrated to improve accuracy. Data was reviewed to support two preliminary clinical targets: hepatic steatosis and adenomyosis screening. For steatosis screening, 314 patients with random US guided biopsies quantitative values of steatosis (\%) from pathology were included. Images were reviewed independently by two radiologists, who identified the region of interest (ROI) most representative of the hepatic echotexture. Images are filtered at multiple scales for various texture responses, including local mean, standard deviation, gradient magnitude, range, entropy, and total oriented wavelet response (Gabor filters). For each response, the samples within the ROI patch are summarized by mean, standard deviation, kurtosis, and skew to create a 36 feature vector for each image. A support vector machine (SVM) is used to classify the images. Using a threshold of 15\%, we achieved 79.62\% accuracy in classifying normal and abnormal livers (p\ensuremath{<}0.5x10-6). Sensitivity was 78.06\% and specificity was 84.62\%. Extending this framework to adenomyosis, 50 patients with MR confirmed findings of adenomyosis and previous ultrasound image studies were identified, 38 controls were also collected.

    abstract = "Purpose: Image-guided percutaneous ablation is an effective, inexpensive, and accessible treatment for liver, lung, and kidney cancers. However, because of its relatively high recurrence rate, percutaneous ablation is usually considered to be palliative only. We hypothesize that the high recurrence rate is due in part to poor margin control resulting from inaccurate treatment models in procedure planning. To address this shortcoming, we are developing a thermal simulation model for percutaneous cancer ablation from first principles. Methods: Our model uses finite element methods to solve Penne's Heat Equation and Maxwell's equations for electromagnetic energy transfer in matter over time. The simulation accounts for applicator geometry and materials as taken from actual clinical devices, and incorporates appropriate density, thermal conductivity properties, dielectric properties, power dissipation, and the relative water content for a homogeneous liver tissue domain. Results: The solution generated is a continuous 3D thermal profile over time. The simulated 60 degree Celsius isotherm at 60 watts for 10 minutes in homogenous liver tissue is accurate to within approximately 5\% (i.e., an average 2mm variance from a 36mm expected width) of the vendor specification and within 12\% (5mm) of our own ex vivo ablation procedures as measured by 4D CT and visual inspection of the coagulation zone. Simulations at other input settings give similar results within 5\%-15\% of expected and empirically observed results. Conclusion: This promising initial model forms the basis of ongoing work in principled thermal simulation for ablation planning. Our next goals are to incorporate heterogeneous tissue types and heat sinks in the solution domain and validate the resulting simulation against our ongoing clinical data collection.",

    abstract = "BACKGROUND Early termination of prolonged seizures with intravenous administration of benzodiazepines improves outcomes. For faster and more reliable administration, paramedics increasingly use an intramuscular route. METHODS This double-blind, randomized, noninferiority trial compared the efficacy of intramuscular midazolam with that of intravenous lorazepam for children and adults in status epilepticus treated by paramedics. Subjects whose convulsions had persisted for more than 5 minutes and who were still convulsing after paramedics arrived were given the study medication by either intramuscular autoinjector or intravenous infusion. The primary outcome was absence of seizures at the time of arrival in the emergency department without the need for rescue therapy. Secondary outcomes included endotracheal intubation, recurrent seizures, and timing of treatment relative to the cessation of convulsive seizures. This trial tested the hypothesis that intramuscular midazolam was noninferior to intravenous lorazepam by a margin of 10 percentage points. RESULTS At the time of arrival in the emergency department, seizures were absent without rescue therapy in 329 of 448 subjects (73.4\%) in the intramuscular-midazolam group and in 282 of 445 (63.4\%) in the intravenous-lorazepam group (absolute difference, 10 percentage points; 95\% confidence interval, 4.0 to 16.1; P\ensuremath{<}0.001 for both noninferiority and superiority). The two treatment groups were similar with respect to need for endotracheal intubation (14.1\% of subjects with intramuscular midazolam and 14.4\% with intravenous lorazepam) and recurrence of seizures (11.4\% and 10.6\%, respectively). Among subjects whose seizures ceased before arrival in the emergency department, the median times to active treatment were 1.2 minutes in the intramuscular-midazolam group and 4.8 minutes in the intravenous-lorazepam group, with corresponding median times from active treatment to cessation of convulsions of 3.3 minutes and 1.6 minutes. Adverse-event rates were similar in the two groups. CONCLUSIONS For subjects in status epilepticus, intramuscular midazolam is at least as safe and effective as intravenous lorazepam for prehospital seizure cessation.

"Collectively, they have once again produced an excellent text that manages to cover the broad scope of emergency medicine while remaining an easily readable and practical resource....Last, for the inevitable comparison of this current edition of Tintinalli's Emergency Medicine with other available emergency medicine textbooks available: in my opinion, Tintinalli's still comes out on top. It is more concise and easier to read than some, yet it covers the breadth of emergency medicine practice more comprehensively than others. The bottom line is that I like this book. Just as previous editions did, the seventh presents all of the most pertinent and up-to-date information in a well-organized format that is comprehensive yet easy to read. That and many of the attractive new features in this current edition will ensure its place on my bookshelf for years to come."--JAMA With 418 contributors representing over 120 medical centers around the world, Tintinalli's Emergency Medicine is the most practical and clinically rigorous reference of its kind. It covers everything from prehospital care, disaster preparedness, and basic resuscitative techniques, to all the major diseases requiring emergency treatment, such as pulmonary emergencies, renal and GU disorders, and hemophilia. This authoritative, in-depth coverage makes this classic text indispensible not only in emergency departments, but also for residents and practitioners when studying or preparing for any exam they may face. While continuing to provide the most current information for acute conditions, the Seventh Edition of Tintinalli's Emergency Medicine has been substantially revised and updated to cover all of the conditions for which patients seek emergency department care in a concise and easy-to-read-manner. NEW Features Full-color design with more figures and tables than ever Reader-friendly chapter presentation makes it easy to find important material. Updated tables covering drugs and important clinical information Patient safety considerations and injury prevention are integrated into chapters, as appropriate Total revision of the dermatology section enables diagnosis by lesion description and body area affected, and provides current treatment Organ systems sections reorganized to reflect considerations for actual clinical practice. New chapters: New adult chapters include Natural Disasters, Aneurysms of the Aorta and Major Arteries; Hip and Knee Pain, Aortic Dissection; Acute Urinary Retention; Subarachnoid Hemorrhage and Intracranial Bleeding; Clotting Disorders; Community {\textendash}acquired Pneumonia and Noninfectious Pulmonary Infiltrates; Type I Diabetes; Type II Diabetes; Anemia; Tests of Hemostasis; Clotting Disorders; Head Injury in Adults and Children; the Transplant Patient; Grief, Death and Dying; and Legal Issues in Emergency Medicine. Twelve new pediatric chapters including The Diabetic Child, Hematologic-Oncologic Emergencies, Ear and Mastoids, Eye Problems in Infants and Children, Neck Masses, GI Bleeding, Nose and Sinuses, Urologic and Gynecologic Procedures in children, Renal emergencies in children, Behavioral and Psychiatric Disorders in children, Pediatric Procedures, Pediatric ECG Interpretation Greater coverage of procedures throughout for the most common conditions seen in the emergency department. Companion DVD features an additional 17 chapters, such as Hyperbaric Oxygen Therapy, Principles of Imaging, Prison Medicine, Military Medicine, The Violent Patient, Forensics, Wound Ballistics, and Drug Interactions. Companion DVD also features videos and animations for teaching and learning performance of important procedures, especially Ultrasound-Guided Procedures},

    abstract = "Purpose: Explicit deformable shape models (DSMs) can be used in a Bayesian statistical framework to provide a prioriinformation for posterior optimization to match the DSM against a target image for automatic segmentation. In this approach a DSM is initialized in the target image and undergoes a series of deformations to closely match the target object. Deformation is driven by optimizing an objective function with terms for geometric typicality (prior) and model-to-image match (likelihood). The purpose of this work was to develop strategy, methodology, and tools for constructing the geometric prior and intensity likelihood for a particular form of DSM called m-reps. Method and Materials: Geometric truth is defined for an object of interest by a statistically significant collection of expert human segmentations of training images. M-reps are fit to the human drawn contours by minimizing the distance between the surfaces of the m-rep and the contours under added conditions that lead to positional correspondence across training cases. The geometry of the resulting set of training m-reps is analyzed in non-Euclidean space using an approach called principal geodesic analysis (PGA) to yield a set of eigenmodes that define the geometric prior. The intensity likelihood is constructed by registering each training m-rep with the corresponding gray scale image and collecting regional intensity information that is statistically characterized over all training cases. The intensity information can be in several forms including linear profiles and regional histograms. Results: PGA produces modes that include natural deformations such as local twisting, bending, bulging, and constricting. Unlike analysis in Euclidean space, improper shapes are avoided. The form of the intensity prior can be customized to each object of interest for optimal performance. Conclusion: These methods are powerful, robust and generalizable to other DSMs.",
