Aortic dissection type I in a weightlifter with hypertension: A case report

Acute aortic dissection can occur at the time of intense physical exertion in strength-trained athletes like weightlifters, bodybuilders, throwers, and wrestlers

Duodenal carcinoma at the ligament of Treitz. A molecular and clinical perspective

Background There is very small occurrence of adenocarcinoma in the small bowel. We present a case of primary duodenal adenocarcinoma and discuss the findings of the case diagnostic modalities, current knowledge on the molecular biology behind small bowel neoplasms and treatment options. Case The patient had a history of iron deficiency anemia and occult bleeding with extensive workup consisting of upper endoscopy, colonoscopy, capsule endoscopy, upper gastrointestinal series with small bowel follow through and push enteroscopy. Due to persistent abdominal pain and iron deficiency anemia the patient underwent push enteroscopy which revealed adenocarcinoma of the duodenum. The patient underwent en-bloc duodenectomy which revealed T3N1M0 adenocarcinoma of the 4th portion of the duodenum. Conclusions Primary duodenal carcinoma, although rare should be considered in the differential diagnosis of occult gastrointestinal bleeding when evaluation of the lower and upper GI tract is unremarkable. We discuss the current evaluation and management of this small bowel neoplasm

Enhanced tetris legalization

Legalization and detailed placement methods for standard cell designs, are two of the most notable topics in current VLSI research. Being the final steps in a classic placement procedure they must be efficient in terms of the delay overhead they introduce to the overall design flow and the quality of the final solution. In this paper we present a combined solution of the aforementioned steps, based on Tetris a particular simple and fast legalization algorithm, that produces considerable results taking into account the tradeoff between total wirelength, total cell displacement and runtime. © 2016 ACM
