Heart block and cardiac embolization of fractured inferior vena cava filter.

Objective: A 66-year-old man underwent a placement of an inferior vena cava filter before a gastric surgery 9 years prior, presented to the emergency room with a complete atrioventricular block. Chest x-ray and transthoracic echocardiogram showed struts migrating to right ventricle with tricuspid regurgitation. Cardiothoracic surgery was consulted and declined an open surgical intervention due to the location of the embolized fragments and the patient's overall condition.

Management of ventricular tachycardia in patients with structural heart disease.

Patients with structural heart disease and ventricular tachycardia (VT) can be difficult to manage clinically. Many treatment options are available, but no single approach can be applied to every patient. This review aims to discuss the current options available for the management of this population.

Robust replication of genotype-phenotype associations across multiple diseases in an electronic medical record.

Large-scale DNA databanks linked to electronic medical record (EMR) systems have been proposed as an approach for rapidly generating large, diverse cohorts for discovery and replication of genotype-phenotype associations. However, the extent to which such resources are capable of delivering on this promise is unknown. We studied whether an EMR-linked DNA biorepository can be used to detect known genotype-phenotype associations for five diseases.

Recovery following propofol-associated brugada electrocardiogram.

Brugada syndrome is a genetic disorder associated with an increased risk of sudden cardiac death that has typical electrocardiographic (ECG) patterns. Recently, there have been reports of Brugada ECG patterns seen in critically ill patients who received propofol,(1) and this pattern was associated with a very high imminent mortality. We report a case in which a critically ill patient developed a Brugada ECG pattern following high-dose propofol infusion.

The accuracy and completeness of data collected by prospective and retrospective methods.

Objectives: To describe and test a model that compares the accuracy of data gathered prospectively versus retrospectively among adult emergency department patients admitted with chest pain.

Methods: The authors developed a model of information flow from subject to medical record to the clinical study case report form, based on a literature review. To test this model, a bidirectional (prospective and retrospective) study was conducted, enrolling all eligible adult patients who were admitted with a chief complaint of chest pain.

Duration of symptoms and follow-up patterns of patients discharged from the emergency department after presenting with abdominal or flank pain.

Background: Little is known about the duration of symptoms and follow-up patterns of patients seen in emergency departments for abdominal or flank pain.

Objective: We aimed to measure the duration of symptoms and follow-up rate of patients discharged home from the emergency department after presenting with non-traumatic abdominal or flank pain.

Methods: We conducted a single-centre, prospective descriptive study of adult patients who presented to our emergency department with non-traumatic abdominal or flank pain and were discharged from the emergency department.

Use of diagnostic testing in the emergency department for patients presenting with non-traumatic abdominal pain.

The objective of the study was to measure the utilization and diagnostic value of tests used in the Emergency Department (ED) on patients with undifferentiated non-traumatic abdominal or flank pain. Specific goals were to measure how often these tests led to changes in diagnosis or disposition, which tests were most commonly used, and which tests providers considered most helpful. We conducted a pilot single-center, prospective descriptive study, enrolling all eligible adult patients who presented to our ED with non-traumatic abdominal or flank pain during defined hours of our intake period.

The relation among spinal geometry on MRI, paraspinal electromyographic abnormalities, and age in persons referred for electrodiagnostic testing of low back symptoms.

Study Design: A retrospective EMG study with blinded radiologic measurement was conducted.

Objective: To determine the relation among spinal measurements on MRI, paraspinal denervation, and age in patients referred for electrodiagnostic and radiologic evaluation of low back pain.

Summary Of Background Data: Spinal pathology, including disc herniation and spinal stenosis, can cause denervation of the paraspinal muscles.
