Abstract

Background

Degenerative joint disease (DJD) of the temporomandibular joint (TMJ) is an important type of temporomandibular disorders (TMDs) potentially leading to orofacial pain and jaw dysfunction. Magnetic resonance imaging (MRI) is important in TMD diagnosis; however, its diagnostic ability for DJD remains unknown.

Objective

To explore the utility of MRI in diagnosing DJD according to the latest diagnostic criteria for TMD and detecting condylar bone abnormalities and their severity.

Methods

Overall, 122 participants were examined using cone-beam computed tomography (CBCT) and MRI. The sensitivity, specificity, and accuracy of MRI for detecting DJD and different types of TMJ condylar bone abnormalities were calculated (considering CBCT as gold standard); in addition, we tested MRI and CBCT's consistency in scoring five types of condylar bone abnormalities.

Results

The sensitivity and specificity of MRI for DJD were 95.3% and 43.1%, respectively.The MRI sensitivities for condylar flattening, erosion, osteophytes, sclerosis, and cysts were 98.6%, 96.2%, 79.4%, 50%, and 79.2% (specificity, 53.6%, 48.3%, 81.6%, 83.3%, and 88.2%, respectively), respectively. The consistency between MRI and CBCT in assessing the severity of condylar bone abnormalities was fair-to-moderate (kappa coefficient: 0.278-0.491). The inter-observer consistency for CBCT was good, whereas for MRI it was relatively poor.

Conclusion

MRI can detect DJD and condylar bone abnormalities. However, MRI could not efficiently detect the severity of condylar bone abnormalities.

Broadly Neutralizing Antibodies for HIV Treatment: Broad in Theory, Narrow in Reality

Abstract
In this viewpoint we briefly review the status of antiretroviral therapy, its unmet needs, and the role that broadly neutralizing antibodies (bNAbs) might have in the near future for the treatment of HIV. We summarize advances in the development of bNAbs as antiretroviral therapy, the results of main clinical trials of bNAbs for HIV treatment and prevention, and its role in cure trials. The limitations of broadly neutralizing antibodies are the current need for primary re sistance testing, the still unclear number of antibodies that must be combined, the lack of penetration in anatomical reservoirs and the role they might play in cure studies. We compare the advantages and disadvantages of "classical ART" and therapy based on broadly neutralizing antibodies. We conclude that broadly neutralizing antibodies still need considerable improvements before they can be considered an alternative to "classical ART".
