Complicated IVC anomalies: Are they more common than we thought? An experience of 100 MDCT venography examinations

Transmissible cancers, are they more common than thought?

Although many cancers are associated with infectious agents (Ewald and Swain Ewald 2015), only four naturally occurring transmissible cancers have so far been identified in dogs, soft-shell clams and Tasmanian devils (DFT1 and DFT2) (Pye et al. 2015). The recent discovery of DFT2 (Pye et al. 2015) provides an intriguing story to the evolution of transmissible cancers and poses several questions:

Immunodeficiency - “ Much More Common Than We Thought ”

10 years with the development of new genetic techniques more than 100 mutations in various genes were found to be associated with primary immunodeficiencies entities. It should be noted that in some diseases several hundreds of patients were found, while in others only few children were discovered, thus applying that we are dealing with rare situations. Using the same genetic techniques a new c...

More ties than we thought

We extend the existing enumeration of neck tie knots to include tie knots with a textured front, tied with the narrow end of a tie. These tie knots have gained popularity in recent years, based on reconstructions of a costume detail from The Matrix Reloaded, and are explicitly ruled out in the enumeration by Fink and Mao (2000). We show that the relaxed tie knot description language that compre...

Screening trials are even more difficult than we thought they were.

In this issue of the Journal, Black et al. (1) present an important analysis of methodologic pitfalls associated with randomized studies of screening interventions. The authors compare disease-specific and all-cause mortality from the 12 published randomized trials of cancer screening for which these end points were available. In seven of the 12 studies, major inconsistencies were detected in t...
