1/21. Thoracic empyema associated with recurrent colon cancer: report of a case and review of the literature.

    Many types of infections associated with colorectal cancer have been reported. Here, we describe a rare case of thoracic empyema that was observed during immunotherapy for recurrent colon cancer. culture of the pleural fluid yielded streptococcus bovis, which is known to be associated with gastrointestinal lesions, especially colorectal malignancies. The possible correlation between these two clinical entities-empyema and colon cancer-is discussed.

2/21. Infectious endocarditis from streptococcus bovis associated with colonic carcinoma: case report and literature review.

    BACKGROUND: Many studies in the literature have warned of the need for investigation of colonic lesions among patients, especially elderly ones, who have bacteremia and/or endocarditis from streptococcus bovis. bacteremia and infectious endocarditis from streptococcus bovis may be related to the presence of neoplastic lesions in the large intestine and hepatic disease. AIM: This report describes a patient who presented infectious endocarditis from streptococcus bovis associated with colonic carcinoma and tubular-villous adenomas. CONCLUSIONS: The finding of this bacterium among patients with septicemia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. For this reason, complete and detailed investigation of the large intestine must be performed in patients with infectious endocarditis, even in the absence of intestinal symptoms. An increased incidence of this condition or hepatic dysfunction has been reported among patients with infectious endocarditis from streptococcus bovis. patients with infectious endocarditis from streptococcus bovis and normal colonoscopy may be included in the group at risk for developing colonic cancer. The knowledge that there is an association between endocarditis from streptococcus bovis and carcinoma of the colon has important clinical implications. If the lesion can be discovered at an early stage, curative resection may become possible.

3/21. streptococcus bovis endocarditis associated with colonic adenocarcinoma: report of a case.

    streptococcus bovis (S. bovis) endocarditis has been increasing over recent decades, especially among the senile population. A 74-year-old man presented with intermittent fever for two months. He had a past history of aortic dissection and underwent a Bentall operation one year before admission. A Janeway lesion was noted on his right hand and six blood cultures grew S. bovis. He was treated with penicillin-G, 3 microU intravenously, every six hours, and became afebrile three days later. A colonofiberoscopy was carried out despite the absence of any gastrointestinal symptoms, and a 2 x 2 cm mass was found at the cecum, with pathologic proof of adenocarcinoma. The patient died from a massive intracranial hemorrhage on the 23rd hospital day. review of the literature revealed an intimate association between S. bovis bacteremia (or endocarditis) and underlying colonic neoplasia. Failure to be aware of the possible consequences of this combination may lead to detrimental patient prognosis. We strongly advise that every patient presenting with bacteremia or endocarditis due to this organism, even if they are free from gastrointestinal symptoms, should undergo a thorough lower gastrointestinal investigation to rule out colonic neoplasia.

4/21. Late infection of a total knee arthroplasty with streptococcus bovis in association with carcinoma of the large intestine.

    Infection of a total knee arthroplasty with streptococcus bovis in a 76-year-old man that led to the diagnosis of a bowel carcinoma is reported. Investigation revealed a malignancy in the ascending colon with extension into the adrenal gland. S bovis in conjunction with colonic neoplasia has been reported in several orthopedic conditions: vertebral osteomyelitis, discitis, lateral neck abscess, and osteomyelitis of the ileum. The relationship of S bovis to endocarditis, meningitis, brain abscesses, and peritonitis has also been well described. However, S bovis is a rare pathogen infecting joint prostheses and should raise the possibility of a gastrointestinal lesion.

5/21. Non-life-threatening sepsis: report of two cases.

    streptococcus bovis is one of the nonenterococcal species included among the streptococci group D. It is part of the normal bowel flora in humans and animals, but it is also responsible for infectious diseases (10-15% of all cases of bacterial endocarditis). Many cases of bacteremia and metastatic abscesses (spleen, liver, soft tissues, bone, meninges, endocardium) caused by S. bovis were reported as associated with digestive tract diseases, mainly colonic disease, and, in particular colonic neoplasms, or chronic liver diseases. A role in carcinogenesis has been suggested for this microorganism. The authors report two cases of S. bovis sepsis, one associated with colonic neoplasm and the other with liver cirrhosis and gastric carcinoma. Discussion is focused on probable mechanisms that favor gastric colonization and systemic diffusion of S. bovis from the gut in patients with gastrointestinal neoplasms or chronic liver disease and provides clinical recommendations for patients with S. bovis infections.

6/21. Recurrent klebsiella pneumoniae liver abscess in a diabetic patient followed by streptococcus bovis endocarditis--occult colon tumor plays an important role.

    klebsiella pneumoniae is the leading cause of liver abscess in diabetic patients in taiwan. We report the case of a diabetic patient with a history of four episodes of K. pneumoniae liver abscess within 3 years. The patient later developed streptococcus bovis bacteremia originating from a colon tumor with complications of endocarditis, osteomyelitis, and silent splenic abscess. Occult colon tumor may have played an important role in our case, with recurrent infection arising from colonizers of the gastrointestinal tract. As our case shows, the possible association between occult colon tumor and K. pneumoniae liver abscess in diabetic patients should be surveyed.

7/21. gemella endocarditis: consider the colon.

    gemella species, including gemella morbillorum, are part of the normal flora of the human oropharynx, upper respiratory tract and gastrointestinal tract. Differentiation of gemella from viridans streptococci in the laboratory may be difficult. Although uncommonly pathogenic, they have been implicated in a variety of human infections, most notably infective endocarditis. Dental instrumentation appears to be the usual source of infection. The case is reported of gemella morbillorum native valve endocarditis, which was associated with an underlying colonic carcinoma. An association with colonic neoplasm has been described in three previous cases of endocarditis attributed to gemella. It is well documented that streptococcus bovis endocarditis may occur in the setting of colonic neoplasia. It is suggested that colonic investigation should be considered in patients with gemella endocarditis, in whom no other source is apparent.

8/21. Streptococcus salivarius meningitis and colonic carcinoma.

    Streptococcus salivarius caused fulminant meningitis in an elderly patient. A gastrointestinal diagnostic workup revealed an asymptomatic colonic adenocarcinoma. This first reported instance of S salivarius sepsis associated with a colonic neoplasm is not unexpected, since the organism is bacteriologically similar to S bovis, the prime bacterial indicator of occult malignancy. Exact speciation of streptococcal strains is fraught with technical difficulties, and gastrointestinal investigation may be warranted in an expanded variety of streptococcal infections.

9/21. streptococcus bovis bacteraemia: its significance for the colorectal surgeon.

    patients with streptococcus bovis bacteraemia are at high risk of harbouring an asymptomatic colorectal cancer or adenomatous polyps. It is therefore important to differentiate to a species level any Group D streptococci grown in blood cultures. colonoscopy is the preferred method of screening these patients and high dose penicillin is the antibiotic of choice.

10/21. streptococcus bovis brain abscess associated with an occult colonic villous adenoma.

    streptococcus bovis is now recognized as a common cause of bacterial endocarditis. However, infection of the central nervous system by this organism is very rare. Recent studies have demonstrated the association between streptococcus bovis infections and colonic neoplasms.
