[Lactose malabsorption in patients with inflammatory bowel disease without activity: would it be necessary to exclude lactose products in the diet of all patients?].

INTRODUCTION: There are inflammatory bowel disease (IBD) patients avoid lacteal products without evidence of lactose malabsorption, probably because of incorrect patient perceptions and arbitrary advice from physicians and diet books. AIM: To evaluate the prevalence of lactose malabsorption in patients with IBP. METHOD: In 18 patients with Crohńs disease and 24 with ulcerative colitis and 25 controls the prevalence of lactose intolerance, as measured by lactose breath hydrogen tests. RESULTS: Observed deficiencies of absorption of the lactose in 7 (16.6%) patients with IBP and 5 (20%) subjects control. CONCLUSIONS: Not all the patients with IBD are intolerant to the lactose by the suppression of the lacteal produts must not be generalized in the diet of these patients.

[Vascular complications associated with inflammatory bowel disease].

Thromboembolic episode is a well known extraintestinal manifestation of inflammatory bowel disease, but it is a clinical rare complication. Histological and hematological studies suggest that a hypercoagulable state is involved in the pathogenesis of inflammatory bowel disease. However, the exact mechanism of hypercoagulability is still unknown. During the acute recurrences there is an increase of factor VIII, fibrinogen, platelet, factor V and decrease of antithrombin III. Hematologic disorders seem markedly correlated with the activity of the disease. We report on two patients with Inflammatory bowel disease and hypercoagulable state. We review the literature and discuss about the pathogenic mechanisms of such complication.

[Complication associated with celiac disease].

Enteropathy associated T cell lymphoma is the most serious complication of celiac sprue. The incidence of malignancy, in general, is approximately twofold greater in celiac disease than in the general population, but the risk of specific gastrointestinal malignancies is markedly increased. Lymphoma of the small intestine, comprises approximately 50% of the malignancies, and the most are of T-cell origin. We report a case of celiac disease associated T-cell Lymphoma of the jejunum in a woman. At the age of 33 the diagnosis of Celiac sprue was made, after institution of a gluten free diet the patient improved, but, fifteen year later, the patient begin with fever and abdominal pain. Laparotomy showed a perforation of the intestine by a tumour.

Ultrasound-guided fine-needle aspiration biopsy. Study of the cost per patient and comparison with computed tomography-guided biopsy.

Between February 1992 and July 1995, we performed 222 ultrasound-guided fine-needle aspiration biopsies (FNAB) in abdominal space-occupying lesions. The sensitivity was 90% and the specificity, 100%, with an overall diagnostic precision of 93%. We also determined the cost of each procedure (2,550 pesetas) and compared it with the cost of computerized tomography (CT)-guided biopsy (22,500 pesetas). These results and those reported in the literature indicate that there is no significant difference with respect to diagnostic yield, but that the difference in terms of expense is considerable. We believe that, in the assessment of abdominal lesions. CT-guided FNAB should be reserved for those lesions that prove inaccessible to ultrasound.

[Sexuality in ostomy patients].

Seventy adult patients out of 446 with surgical stomas were investigated to ascertain the degree of sexual disfunction caused by the operation. A questionnaire of 74 items was given to all patients. Statistical analysis was done for crossing variables using Chi Square calculations. Sexual activity decreased much more in males than in females, independently of age but in relation to the type of operation.
