[Ciprofloxacin vs cefazolin in the prevention of infection in cirrhotic patients with gastrointestinal bleeding].

Aim: To determine if prophylaxis with cefazolin produces a significant reduction in infections in cirrhotic patients with gastrointestinal bleeding when compared with ciprofloxacin.

Methods: Randomized clinical trial. Patients 18 years or older with diagnosis of cirrhosis, gastrointestinal bleeding and no clinical or laboratory evidence of infection who were admitted to the gastrointestinal bleeding unit of HNERM between July 2008 and July 2010 were included.

[Obscure digestive bleeding by ileal carcinoid tumor].

The patient is an 82 year-old female with a history of osteoarthritis, hypothyroidism and anemia for 14 years (receiving blood transfusions). She was admited to our hospital with a nine months history of malaise, anorexia, fatigue and weakness, associated with intermitten episodes of abdominal pain. She was diagnosed anemia and occult blood positive stools.

[Bleeding in digestive tract caused by jejunal angiodysplasia: complementary value of capsule endoscopy and double-balloon enteroscopy].

We report the case of a 35-year-old male patient, with a history of six months of pallor and dyspnea associated with severe iron deficiency anemia and positive fecal occult blood tests. Endoscopy of the lower and upper gastrointestinal tract, and a small bowel follow-through were performed, but did not reveal the origin of the bledding. Later, a capsule endoscopy study were performed and detected an elevated area - not well defined - with active bleeding in the jejunal portion of the small bowel, for that reason we decided to complement the study with a double balloon enteroscopy, that allowed us to see more clearly the jejunal lesion: an elevated and ulcerated lesion; the area was marked with India ink to guide the surgeon.
