Atypical diagnosis diagnosis by endoscopic capsule: Whipple's disease.

Whipple's disease is a chronic systemic infection produced by the actinomycete Tropheryma whipplei. Endoscopic tests are key in the diagnosis as they allow biopsy and histopathological examination for definitive diagnosis of this entity. We present a case of Whipple's disease where capsule endoscopy, uncommon for the diagnosis of this condition, was essential for it and its performance before and after antibiotic treatment allows to describe the macroscopic evolution of the findings in the small bowel.

Endoscopic ultrasonography features of calcified gastric cancer.

Calcifications are a rare finding described in benign and malignant tumors located in any site of the body. Their presence in stomach and colon carcinomas is very rare. Most of the cases described are mucinous adenocarcinomas.

[Endoscopic diagnosis of an ileocolic intussusception in an adult].

Although intussusception is the most frequent cause of intestinal obstruction in children, it only represents 5-10% of all adults. The preoperative diagnosis is difficult and it is rarely done by endoscopy. We present a case of adult ileocolic intussusception caused by an ileon terminal hamartoma.

Nitrite/nitrate and cytokine levels in bronchoalveolar lavage fluid of lung cancer patients.

Background: Cytokines are produced by tumor cells in vitro, but evidence for in vivo increased production of cytokines in cancer patients is controversial. Conversely, nitric oxide (NO) is implicated increasingly in the mediation of cytokine effects. Lung cancer patients may show an increased local production of cytokines and NO, and chronic paracrine exposure of epithelial lung cells to these medicators may influence the production of surfactant phosphatidylcholine.

Acetylator polymorphism in human colorectal carcinoma.

Acetylator phenotype has been determined using sulfamethazine in 109 patients histologically diagnosed with colorectal carcinoma (resected in 74 patients by the time of the study) and in 96 age-matched controls. Fifty-five % of patients and 58.3% of controls were classified as slow acetylators (chi 2 = 0.

Cancer of the gastric stump.

28,500 fiberoptic endoscopies were reviewed. 97 cancers of the stump were found in 1,119 patients who had had gastric resection (8.66%), in contrast to the 3.

Spontaneous intramural oesophageal perforation.

Spontaneous intramural oesophageal perforation appears at any level, but preferably on the posterior wall, and is usually longitudinal. Unlike the Mallory Weiss and the Boerhaave syndromes, females are more frequently affected. It appears with sudden retrosternal pain radiating to the epigastrium, neck and back, followed by haematemesis of small quantity and dysphagia.
