Abstract

Light chain deposition disease (LCDD) is a rare clinicopathologic entity first described in 1976 and is characterized by a monoclonal gammopathy resulting in nonamyloid immunoglobulin light chain tissue deposition. Only four cases of intracerebral LCDD have been previously reported, all in the setting of a known plasma cell dyscrasia or in the presence of local mature plasma cells. We present the first case of intracranial LCDD in the absence of a known plasma cell dyscrasia or local mature plasma cells.

Abstract

To assess and determine the overall interdisciplinarity and impact of radiology and imaging sciences research.Utilizing the Thomson Reuters Web of Science, the top 15 journals rank-ordered by impact factor in each of 10 major medical subspecialties were identified. The 2012 impact factors for these journals were noted. All articles published in these journals between 2012 and 2014 were then used to produce an index list of publications. We next generated a list of all published articles in the ensuing 5-year period that cited any publication present on our index list. These data were then used to calculate an interdisciplinarity score (DIV*) for 146 unique scientific journals. The correlation between the impact factor and the DIV* score was calculated with Kendall's τ.The quantitative measure of research interdisciplinarity, DIV*, is significantly correlated with journal impact factor (τ = 0.201, p 0.001). Research journals within radiology, nuclear medicine, and medical imaging ranked 5th among 10 clinical subspecialties by mean impact factor but ranked second-to-last in mean DIV*.The interdisciplinarity score DIV* is positively correlated with journal impact factor, demonstrating the greater impact and reach of interdisciplinary research. Further, we found radiology, nuclear medicine, and medical imaging research to have one of the lowest measures of DIV* among the 10 major clinical subspecialties. Our findings suggest and point to new opportunities and directions that can expand the breadth and impact of radiology research as well as new ways to increase our reach and audience in the clinical scientific literature.

Abstract

PHACE syndrome is a rare neurocutaneous disorder characterized by posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, and abnormalities of the eye. Thyroid disorders associated with PHACE syndrome have been described, although there are limited reports of this rare occurrence. We report a case of PHACE syndrome with congenital hypothyroidism in an infant, for which absent thyroid gland was diagnosed at magnetic resonance imaging.
