Gastric bypass is the preferred operation for treatment of morbid obesity on many services. The evaluation of the excluded stomach is always difficult and a matter of concern for the attending physician. There are only four reported cases of gastric cancer in the distal stomach after gastric bypass. We report a 57-year-old man who had intestinal metaplasia at the time of the Roux-en-Y gastric bypass 4 years ago and now developed an aggressive carcinoma in the bypassed stomach.
As plaquetas são fragmentos citoplasmáticos anucleados presentes no sangue e produzidos na medula óssea a partir dos megacariócitos. O objetivo deste trabalho é rever as bases mecanísticas e moleculares das plaquetas, revelando sua participação em síndromes importantes e na trombose arterial, além de seu potencial como alvo terapêutico para o desenho de novos agentes antitrombóticos.
