Active rehabilitation for chronic low back pain: Cognitive-behavioral, physical, or both? First direct post-treatment results from a randomized controlled trial [ISRCTN22714229]

Background  

The treatment of non-specific chronic low back pain is often based on three different models regarding the development and maintenance of pain and especially functional limitations: the deconditioning model, the cognitive behavioral model and the biopsychosocial model.     

Pathological features and mucin histochemistry of primary gastric stump carcinoma associated with gastritis cystica polyposa. A study of six cases

Six unusual cases of primary gastric stump carcinoma associated with gastritis cystica polyposa and arising in old gastrojejunostomy stomas are presented. The clinical data, the gross and microscopic pathological features, and the histochemical mucin profile of these two lesions are described in detail. A review is undertaken of the most relevant and previously published reports concerning, separately, either primary gastric stump carcinoma or gastritis cystica polyposa. The findings available in these reports are compared with those observed in our six cases. Some aspects of gastritis cystica polyposa are not unlike those seen in the solitary ulcer syndrome of the rectum and Ménétrier's disease. The histological type and mucin profile of primary gastric stump carcinoma parallel those recorded in gastric cancer arising in the unoperated stomach. However, the role of intestinal metaplasia and its histochemical typing appear somewhat different in primary gastric stump carcinoma.     

Primary lymphoma of the liver: an uncommon disease. Ultrasonic and x-ray computed tomographic aspects. Apropos of a case with review of the literature

Although the very rare primary non-Hodgkin's lymphoma is resectable and responds to chemotherapy it has a very poor prognosis since the outcome was rapidly fatal in 7 of the 11 cases reported in the literature. Particular features in a patient with a primary non-Hodgkin's lymphoma of cirrhotic liver were the association of portal hypertension and portal thrombosis related to tumor invasion. Findings on ultrasound imaging and histologic diagnosis from guided needle puncture biopsy appear to be previously unreported aspects of this affection.
