OBJECTIVE. The purpose of this article is to review the epidemiologic aspects of cervical cancer, the 2018 revised International Federation of Gynecology and Obstetrics (FIGO) staging system, and the role of imaging in the staging of cervical cancer. CONCLUSION. Cervical cancer has many prognostic factors, some of which, such as lymph node metastasis, were not included in the original FIGO staging system. FIGO has issued a revised staging system that encompasses additional prognostic factors to facilitate adequate management.OBJECTIVE. Breast density notification laws have grown from the first state legislation in Connecticut in 2009 to a federally mandated update to the Mammography Quality Standards Act in 2019. CONCLUSION. The increasing recognition of limited mammographic sensitivity in women with dense breasts has led to greater utilization of supplemental screening ultrasound. Robust data support improved detection of small node-negative invasive breast cancers with adjunctive ultrasound. Digital breast tomosynthesis and other emerging modalities may also play a role in screening guidelines.OBJECTIVE. The purpose of this review is to provide a guide for radiologists that explains the language and format of modern genomic reports and summarizes the relevance of this information for modern oncologic imaging. CONCLUSION. Genomic testing plays a critical role in guiding oncologic therapies in the age of targeted treatments. Understanding and interpreting genomic reports is a valuable skill for radiologists involved with oncologic imaging interpretation.OBJECTIVE. CT or MRI is most commonly used for characterizing focal hepatic lesions. However, findings on CT and MRI are occasionally indeterminate. Contrast-enhanced ultrasound (CEUS), with its unique characteristics as a purely intravascular contrast agent and real-time evaluation of enhancement, is a useful next step. The purpose of this article is to review the evidence for performing CEUS in the assessment of indeterminate hepatic lesions seen on CT and MRI. CONCLUSION. CEUS is a useful problem-solving tool in the evaluation of liver lesions that are indeterminate on CT and MRI. Uses include detection of arterial phase hyperenhancement; differentiation between hepatocellular carcinoma and intrahepatic cholangiocarcinoma; determination of benign versus malignant tumor thrombus, benign versus neoplastic cystic hepatic lesions, and hepatocellular adenoma versus focal nodular hyperplasia; and monitoring for recurrence in postablative therapies. CEUS can help establish a confident diagnosis and determine the need for further invasive diagnosis or treatment.OBJECTIVE. The purposes of this article are to review currently available hepatobiliary contrast agents, discuss techniques for optimization of pediatric liver MRI with hepatobiliary contrast agents, and review the imaging features of several pediatric hepatic lesions, focusing on their assessment with hepatobiliary contrast agents. CONCLUSION. MRI is the preferred imaging modality for complete assessment of focal liver lesions in the pediatric population. Imaging with gadolinium-based hepatobiliary contrast agents yields beneficial information about many focal liver lesions encountered in pediatric patients.Purpose This study examined whether young children with normal hearing demonstrated negative attitudes toward peers wearing hearing aids, often described as the "hearing aid effect." The effect of age on these attitudes was also examined. Method Forty-five typically developing children with normal hearing, aged 6-11 years, were recruited to answer questions about and rate photos of children with and without hearing aids in areas of peer acceptance as well as physical and cognitive competence. Participants completed a forced-choice task, a perceived competence rating task, and a sociometric rating task. Results Children in this study perceived their peers who wore hearing aids as having less physical competence and less peer acceptance than peers without hearing aids, thus confirming a hearing aid effect in children as young as 6 years of age. Both younger and older children were more likely to choose pictures of children wearing hearing aids as having less peer acceptance than pictures of children who were not wearing hearing aids. Older children were also more likely to choose a picture of a child with hearing aids as having less physical competence than a picture of a child without hearing aids. Conclusion These findings should serve to alert professionals who work with children who have hearing loss that additional support and education might be warranted for these children and their peers with normal hearing.BACKGROUND Femoral tunnels that are not anatomically placed within the native anterior cruciate ligament (ACL) footprint during ACL reconstruction are associated with residual instability, graft rupture, and poor clinical outcomes. Although surgeons may intend to place their femoral tunnels within the native ACL attachment, this is not always achieved. This study assesses the variation between intended and achieved femoral tunnel positions in a large cohort of experienced ACL surgeons. HYPOTHESIS The accuracy with which experienced ACL surgeons achieve their intended femoral tunnel position is dependent on viewing portal, localization strategy, and drilling technique. STUDY DESIGN Controlled laboratory study. METHODS A total of 221 surgeons indicated their intended femoral tunnel location on a true lateral radiograph of a cadaveric knee specimen and a scaled photograph. Each surgeon then arthroscopically demonstrated the femoral tunnel on the specimen. The position was captured using fluoroscopy. The Euclideaion. Fluoroscopy may be particularly useful for cases where the native femoral stump is no longer visible and for revisions. Viewing through the AM portal is recommended to aid accuracy of tunnel placement.The airway epithelium plays a critical role in innate responses to airborne allergens by secreting IL-1 family cytokines such as interleukin (IL)-1α and IL-33, as alarmins that subsequently orchestrate appropriate immune responses. Zelavespib Previous studies revealed that epithelial IL-33 secretion by allergens such as A. alternaria (ALT) or house dust mite (HDM) involves Ca2+-dependent signaling, via initial activation of ATP-stimulated type 2 purinoceptors (P2YR2) and subsequent activation of the NADPH oxidase DUOX1. We sought to identify proximal mechanisms by which epithelial cells sense these allergens, and here highlight the importance of protease-activated receptors (PAR2) and transient receptor potential (TRP) Ca2+ channels such as TRP Vanilloid 1 (TRPV1) in these responses. Combined studies of primary human nasal and mouse tracheal epithelial cells, as well as immortalized human bronchial epithelial cells (HBE1), indicated the importance of both PAR2 and TRPV1 in IL-33 secretion by both ALT and HDM, based on both pharmacological and genetic approaches.
