[Giant esophageal hematoma: possible association with low-dose aspirin]. / Hematoma esofágico gigante: posible relación con dosis pequeñas de aspirina.

Esophageal hematoma is a rare entity that usually presents as acute thoracic pain. It may occur spontaneously or in association with an underlying disease or direct esophageal damage. The presence of coagulation disorders plays an important role in the development of hematoma. We describe the case of a female patient treated with low-dose aspirin who was diagnosed through emergency gastroscopy. We also review the literature and discuss possible causes, findings in diagnostic tests and treatment.

[Inflammatory bowel disease and amyloidosis]. / Enfermedad inflamatoria intestinal y amiloidosis.

Secondary (AA) amyloidosis is a rare but serious complication of longstanding inflammatory bowel disease that can affect the patient's prognosis more than the underlying disease. Although early diagnosis of this complication is becoming more frequent, its effective treatment continues to pose a challenge to the clinician. We present two cases of Crohn's disease complicated by secondary amyloidosis after two years, and describe their outcome.

Epidemiological aspects of inflammatory bowel disease in the Pamplona area.

OBJECTIVES: to analyze retrospectively our hospital records on patients diagnosed during the period from 1983 to 1993 as having Crohn's disease or ulcerative colitis, and to estimate the incidence and epidemiological characteristics of these diseases in the Pamplona health administration area. METHODS: 246 patients were diagnosed has having inflammatory bowel disease (147 with ulcerative colitis, 97 with Crohn's disease, and 2 with indeterminate colitis. RESULTS: mean incidence was 2.47 +/- 0.96 per 100 000 inhabitants for Crohn's disease, and 3.75 +/- 1.5 per 100 000 inhabitants for ulcerative colitis (p < 0.05). There was a nonsignificant increase in incidence during the study period. Age, sex, alcohol intake, smoking habit and familial aggregation were analyzed. CONCLUSIONS: mean estimated incidence of Crohn's disease and ulcerative colitis in our setting during 1983-1993 was similar to that reported more recently for other parts of Spain. In our setting, ulcerative colitis was significantly more frequent that Crohn's disease, and familial aggregation was lower among patients who had the former disease. Crohn's disease was diagnosed at earlier ages, and cigarette smoking was more frequent among patients with this disease.

[Chronic non granulomatous ulcerative jejunitis]. / Yeyunoileítis ulcerative crónica no granulomatosa.

Chronic non granulomatous ulcerative jejunoileitis a very infrequentity characterized by malabsorption and ulcerations of the small intestine which usually involve the jejunum and ileum. A case of a woman diagnosed with malabsorption syndrome requiring laparotomy due to worsening of a picture of malabsorption and the presence of stenosis and ileal ulceration, demonstrating villous atrophy and lymphoplasmocytic infiltration in the histology compatible with this disease is presented.
