Hodgkin Lymphoma and Castleman Disease: When One Blood Disease Can Hide Another
We describe a rare case of Castleman disease associated de novo with Hodgkin lymphoma. The incidence of Castleman disease is rare; only a few studies have described it in de novo association with Hodgkin lymphoma. The patient described here complained of unique evolutionary axillary adenopathy. A positron-emission tomography/computed tomography scan revealed hypermetabolic activity in this area...
متن کاملIf You Can Hide behind It, Can You Hide inside It?
Let K and L be compact convex sets in Rn. Suppose that, for a given dimension 1 ≤ d ≤ n − 1, every d-dimensional orthogonal projection of L contains a translate of the corresponding projection of K. Does it follow that the original set L contains a translate of K? In other words, if K can be translated to “hide behind” L from any perspective, does it follow that K can “hide inside” L? A compact...
متن کاملPhytobezoar Causing Terminal Ileal Obstruction– Can Enterotomy be Avoided?
Phytobezoar presenting as acute intestinal obstruction is extremely rare in clinical practice and causing terminal ileum obstruction is still rarer. We report a case of middle aged female who presented with intestinal obstruction due to impacted phytobezoar in terminal ileum. Emergency exploratory laparotomy was performed and large phytobezoar found impacted in terminal ileum, which was compres...
متن کاملHow Many People Can Hide in a Terrain?
How many people can hide in a given terrain, without any two of them seeing each other? We are interested in finding the precise number and an optimal placement of people to be hidden, given a terrain with n vertices. In this paper, we show that this is not at all easy: The problem of placing a maximum number of hiding people is almost as hard to approximate as the Maximum Clique problem, i.e.,...
متن کاملSteganography Technique to Hide a Video into Another One via Discrete Wavelet Transform
In this work an algorithm is proposed to hide information, into an .avi video file. Such file is separated in audio and video. The video breaks down in its frames, in which we apply a discrete wavelet transform. Once the image has been separated in frequencies, zones are chosen where the information can be hidden. In this work the source of information is an image. Nevertheless, the procedure c...
