There is much debate in the current literature with regard to the most appropriate hip-specific patient-reported outcome (PRO) measurement for assessment of femoroacetabular impingement syndrome (FAIS) and outcomes after surgical treatment. Despite systematic reviews assessing the validity of classic hip-specific PROs as well as newer PROs developed to target the young, active population, there lacks a direct comparison of the question content between each PRO.

To compare the question composition and degree of overlap between commonly used PROs for FAIS.

Cross-sectional study.

A literature review yielded the 6 most commonly cited PROs for assessment of FAIS modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), Copenhagen Hip and Groin Outcome Score (HAGOS), Nonarthritic Hip Score (NAHS), international Hip Outcome Tool (iHOT-33), and Hip Outcome Score (HOS). Questions from each PRO were classified as identical, similar, or unique after pooled comparison, and the numbsts may be appropriate for use. The iHOT-33, HOOS, and HAGOS are well suited for the general population as they offer comprehensive assessments across all domains, while the HOS provides added focus to sports/activity assessments for athletes and highly active patients.

As there is a high percentage of overlapping (identical or similar) questions between the most commonly used hip-specific PROs for FAIS, multiple tests may be appropriate for use. The iHOT-33, HOOS, and HAGOS are well suited for the general population as they offer comprehensive assessments across all domains, while the HOS provides added focus to sports/activity assessments for athletes and highly active patients.Breast MRI is the most sensitive modality for the detection of breast cancer. However, false-negative cases may occur, in which the cancer is not visualized at MRI and is instead diagnosed with another imaging modality. The authors describe the causes of false-negative breast MRI results, which can be categorized broadly as secondary to perceptual errors or cognitive errors, or nonvisualization secondary to nonenhancement of the tumor. Tips and strategies to avoid these errors are discussed. Perceptual errors occur when an abnormality is not prospectively identified, yet the examination is technically adequate. Careful development of thorough search patterns is critical to avoid these errors. Cognitive errors occur when an abnormality is identified but misinterpreted or mischaracterized as benign. The radiologist may avoid these errors by utilizing all available prior examinations for comparison, viewing images in all planes to better assess the margins and shapes of abnormalities, and appropriately integrating all available information from the contrast-enhanced, T2-weighted, and T1-weighted images as well as the clinical history. Despite this, false-negative cases are inevitable, as certain subtypes of breast cancer, including ductal carcinoma in situ, invasive lobular carcinoma, and certain well-differentiated invasive cancers, may demonstrate little to no enhancement at MRI, owing to differences in angiogenesis and neovascularity. MRI is a valuable diagnostic tool in breast imaging. However, MRI should continue to be used as a complementary modality, with mammography and US, in the detection of breast cancer. ©RSNA, 2021.The anatomy of the temporal bone is complex, and postoperative imaging evaluation of this bone can be challenging. Surgical approaches to the temporal bone can be categorized didactically into tympanoplasty and ossicular reconstruction, mastoidectomy, and approaches to the cerebellopontine angle and internal auditory canal (IAC). In clinical practice, different approaches can be combined for greater surgical exposure. Postoperative imaging may be required for follow-up of neoplastic lesions and to evaluate unexpected outcomes or complications of surgery. CT is the preferred modality for assessing the continuity of the reconstructed conductive mechanism, from the tympanic membrane to the oval window, with use of grafts or prostheses. It is also used to evaluate aeration of the tympanic and mastoid surgical cavities, as well as the integrity of the labyrinth, ossicular chain, and tegmen. MRI is excellent for evaluation of soft tissue. Selleck D-1553 Use of a contrast-enhanced fat-suppressed MRI sequence is optimal for follow-up after IAC procedures. Non-echo-planar diffusion-weighted imaging is optimal for detection of residual or recurrent cholesteatoma. The expected imaging findings and complications of the most commonly performed surgeries involving the temporal bone are summarized in this review.

Further, the latent factor structure underpinning the PCL measures has not been comprehensively validated in Australia. This study examined the construct validity of the PCLSV in a sample of 192 Australian male violent offenders using structural equation modeling. The incremental validity of including the antisocial behavior items for predicting recidivism was also assessed. Approximately one-third of the sample had high scores on the PCLSV. Construct analyses indicated strongest support for two distinct three-factor models of PCL psychopathy, with the established two- and four-factor models demonstrating poorer fit. The Antisocial factor improved predictive accuracy incrementally relative to the other three factors (Interpersonal, Affective, and Lifestyle). Area under the curve analyses revealed predictive accuracy for recidivism only for factors containing the antisocial behavior items. Findings contribute to the construct and predictive validity of the PCL measures and are discussed relative to contemporary forensic risk assessment practice.Babesiosis is a tick-borne disease that is caused by intraerythrocytic protozoan parasites of the genus Babesia. Common symptoms of babesiosis are generally characterized as nonspecific flu-like symptoms, such as fever or chills. Human infections are reported to the Centers for Disease Control and Prevention (CDC) through the National Notifiable Diseases Surveillance System (NNDSS). This study summarizes data of Babesia infections reported to the CDC by the NNDSS from 2011 to 2018. In total, there were 14,159 reported cases of babesiosis, and the incidence rate was 5.55 cases per million persons per year, displaying an increasing trend during the study period. The demographic group most affected was middle-aged and elderly white males. Infections were most abundant in the New England and the Mid-Atlantic regions of the United States. Our study provides useful results for a basic understanding of incidence, spatial and temporal distribution, and severity of babesiosis.
