BACKGROUND: Patients who receive an abnormal cancer screening result require follow-up for diagnostic testing, but the time to follow-up varies across patients and practices. METHODS: We used a simulation study to estimate the change in lifetime screening benefits when time to follow-up for breast, cervical, and colorectal cancers was increased. Estimates were based on four independently developed microsimulation models that each simulated the life course of adults eligible for breast (women aged 50-74 years), cervical (women aged 21-65 years), or colorectal (adults aged 50-75 years) cancer screening...

BACKGROUND: Patella-alta is very common in patients with Cerebral Palsy (CP). While several diagnostic x-ray indices have been developed for patella-alta in general, the specific relationship with walking dysfunction in CP is only partly understood. METHODS: 33 participants with bilateral spastic CP between 4 and 20 years (GMFCS I-II without previous surgery) that underwent 3D gait analysis as well as a radiographic exam within 0.8 (SD 1.2) months were retrospectively included...

BACKGROUND: Tracheobronchomalacia, defined as variable collapse of the airways, has been recognized as an important cause of respiratory morbidity but still widely underdiagnosed. Bronchoscopy is still considered as the gold standard, but numerous limitations are known, especially for fragile sick children. Moreover, information on parenchymal lung disease cannot be described. There is a real need for a reliable, non-invasive test to help detection of airway and parenchymal malformations in children, specifically when bronchoscopy cannot be performed...

INTRODUCTION: The diagnostic accuracy of the FAST exam performed by EM residents were shown to be similar to radiology residents. However, in the last 2 decades, an extended-FAST (E-FAST) protocol including thoracic examination to exclude pneumo- and hemothorax was introduced. The accuracy of emergency physicians (EPs) while performing E-FAST is a less studied area, especially in Europe. The aim of this study was to compare the diagnostic accuracy of the E-FAST exam performed by EM residents with the results of CT scan as a gold standard...

CONTEXT: Range of motion (ROM) is a component of a physical exam used in the diagnostic and rehabilitative process. Following ankle injury and/or during research, it is common to measure plantarflexion with a universal goniometer. The ease and availability of digital inclinometers created as applications for smartphones, has led to an increase in using this method of ROM assessment. Smartphone applications have been validated as alternatives to inclinometer measurements in the knee; however, this application has not been validated for plantarflexion in the ankle...

BACKGROUND: Default pediatric protocols on many digital radiography systems are configured based on patient age. However, age does not adequately characterize patient size, which is the principal determinant of proper imaging technique. Use of default pediatric protocols by inexperienced technologists can result in patient overexposure, inadequate image quality, or repeated examinations. OBJECTIVE: To ensure diagnostic image quality at a well-managed patient radiation exposure by transitioning to thickness-based protocols for pediatric portable abdomen radiography...

Approximately 80% of individuals infected with West Nile virus (WNV) are asymptomatic, and less than 1% suffer from neuroinvasion that can result in permanent neurological deficits or mortality. Our institution's location in southern California predisposes it to a sizable case volume of neuroinvasive WNV. A 2-year retrospective study was performed at the Olive View-UCLA Medical Center to identify patients with confirmed WNV infection with neuroinvasion. Patient demographics, neurological exam findings, and laboratory diagnostics were reviewed...

Background: The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the symptoms. The aim of this general article is to summarize the main examination manoeuvres that could be included in an overall approach to a patient with a suspicion of instability...

REVIEW
Michele Sumler, Ratna Vadlamudi
Heart failure (HF) currently affects more than 5 million patients in the United States [1]. Advanced HF is associated with high mortality and poor quality of life. It is estimated that between 5% and 10% of all patients with HF have an advanced form of the disease [1]. Orthotopic heart transplantation (OHT) is an accepted therapy for stage D HF [3] (Fig. 1). Unfortunately, the number of patients with the disease exceeds the number of available organs. This makes appropriate patient selection vital in the field of heart transplantation...

Introduction: The vast majority of patients presenting with pneumoperitoneum have visceral organ perforation and require urgent diagnostic laparoscopy. Nonsurgical causes are relatively rare and may be attributed to multiple etiologies. Case Presentation: Here we describe the case of a 38-year-old Caucasian female who presented to the emergency department with three days of cramping, epigastric abdominal pain. Her physical exam was notable for tenderness to palpation in the epigastric area and abdominal and chest X-rays showed free air under the diaphragm...

Ear and temporal bone imaging is essential for the diagnostic and preoperative management of middle ear lesions. The scanner is the exam of choice to analyze the walls and the contents of the middle ear. MRI is used to characterize the opacities of the middle ear and to evaluate possible neurological complications. Modern imaging techniques allow intraoperative guidance in otological surgery. Hearing implants are not always a contraindication to MRI but require precautions according to the type of implant.
