We prospectively studied patients with Streptococcus bovis septicemia for the presence of gastrointestinal lesions. This study was prompted by our reported findings of the association of fecal carriage of S. bovis with carcinoma of the colon. We studied 29 patients with 30 episodes of S. bovis septicemia. Fifteen completed gastrointestinal evaluations that included colonscopy, surgery, or autopsy. Eight of these had carcinoma of the colon, three had adenomatous polyps of the colon without carcinoma, and two had carcinoma of the esophagus. The 14 patients who did not have complete evaluations included one each with carcinoma of the stomach, gastric lymphoma, and adenomatous polyp of the colon and three with colonic masses not further delineated. Nineteen patients had no gastrointestinal signs or symptoms or stools positive for occult blood at admission. The results of our study suggest that all patients with S. bovis septicemia need aggressive evaluation of the gastrointestinal tract, especially the colon.

The authors studied on SCC antigen in patients with esophageal carcinoma. Serum SCC antigen was found in 9 (40.9%) of 22 patients with esophageal squamous cell carcinoma and 5 (55.5%) of 9 patients with lung squamous cell carcinoma, but was not found in other malignant diseases, such as gastric cancer, hepatoma, colon cancer, pancreas cancer and biliary try tract cancer. SCC antigen positive cases increased in association with progression of histological invasion, grade of nodal metastasis and clinical stage. However, in early esophageal carcinoma, SCC antigen was rarely positive. There was no positive case in patients with poorly differentiated squamous cell carcinoma regardless of clinical stage. Positive rate of SCC antigen increased in association with progression of clinical stage in patients with moderately and well differentiated squamous cell carcinoma. Immunoreactivity of SCC, which was investigated immunohistologically with TA-4 rabbit serum, was not found in cases with poorly differentiated squamous cell carcinoma, but was found in keratinized portion and cytoplasm of moderately and well differentiated carcinoma. From the above, SCC antigen is intimately related with keratinization of squamous cell carcinoma, and it was thought that it could be useful as a good marker for diagnosis of moderately and well differentiated squamous carcinoma of the esophagus.

Streptococcus bovis bacteremia is an important early clue to the presence of serious and clinically unexpected gastrointestinal disease, particularly carcinoma of the colon. S. bovis bacteremia has also been associated with carcinoma of the esophagus and stomach, gastric lymphoma, pancreatic adenocarcinoma, intestinal diverticulosis and single adenomatous polyps and villous polyps of the colon. We report a patient with S. bovis endocarditis as the initial clinical manifestation of extensive polyposis of the colon and rectum. All patients with S. bovis bacteremia need thorough investigation of their gastrointestinal tract even in the absence of symptoms, signs, or positive laboratory tests suggestive of gastrointestinal pathology.

This is a review of some of the most important growing points in the specialties of gastroenterology and hepatology. It does not aim to be completely comprehensive but to pick out major areas of importance to examination candidates and doctors without special experience in the field. Topics covered include: upper gastrointestinal haemorrhage; Barrett's oesophagus; carcinoma of the oesophagus; achalasia; Helicobacter pylori; duodenal ulcer prevention; coeliac disease; dermatitis herpetiformis; Crohn's disease; small bowel overgrowth; ulcerative colitis; carcinoma of the large bowel; obesity; endoscope sterilisation; gall stones; liver transplantation; autoimmune liver disease; viral hepatitis; metabolic liver diseases; and pancreatic insufficiency.

Esophageal carcinoma represents a great diagnostic and therapeutic challenge due to the anatomical situation and physiopathology of the disease. The medical challenge can be even greater since esophageal carcinoma can evolve concomitant to another malignant tumor with different localization. This paper's aim is to present a case of squamous esophageal cancer associated to another primitive malignant tumor-malignant pericolic conjunctive tumor, this kind of association being singular in medical literature from our knowledge. Upon emergency presentation the patient was sketching a sub-occlusive syndrome with mild anemia and inflammatory syndrome, somehow suggesting a possible right colon cancer. However, discreet upper digestive pole symptomatology that, on first sight, seemed secondary, made the consultant to perform a superior digestive endoscopy that raised a strong suspicion of early stage esophageal carcinoma. Further exploration was not completed because occlusive complication occurred and the patient needed emergency surgery. On laparotomy a stenotic right colic angle tumor was discovered that later proved to be extra-mucosal, with conjunctive origin. Our paper focuses on highlighting the crucial importance of the imagistic explorations in the primary diagnosis of esophageal carcinoma, in the correct staging (lymphatic extension, loco-regional or distant metastases) and also for malignant tumors with another localization that can radically modify the therapeutic strategy.
