An important element of the evaluation of patients with infective endocarditis is the determination of an infectious source. In approximately 20-45% of cases, no source is identified. Often the specific organism involved implicates the source, as is classically described by the association of S. bovis with colonic neoplasia. Other gut organisms have been reported to infect heart valves when colorectal pathology is present, but at far less frequency than S. bovis. This report deals with the case of a 75-year-old man with Enterococcus faecalis endocarditis of an unusual source--a cecal carcinoma that was causing intermittent appendiceal obstruction and infection. This case adds to previous case reports which suggest that the occurrence of enterococcal endocarditis in the absence of a classic infectious source should lead to a search for occult colorectal pathology.

The authors describe a case of metastatic endocarditis associated with a gastric carcinoma. The diagnosis was made early and the treatment by surgery and chemotherapy allowed a survival of 18 months, which is unusually long. The differential diagnosis is discussed and includes nonbacterial thrombotic endocarditis, infectious endocarditis and primary tumors of the heart.

A rare case of neoplastic thrombotic endocarditis of the tricuspid valve in a patient with poorly differentiated follicular carcinoma of the thyroid is described. Although some previous reports documented extension of the follicular thyroid carcinoma into the great veins of the neck to the right cardiac chambers, this seems to be the first report of a neoplastic thrombotic lesion of the tricuspid valve in a patient with thyroid carcinoma. In our institute, where about 2,500 autopsies are performed yearly, and about 600 valvular lesions are discovered, such a lesion was never detected. In patients with carcinoma, a neoplastic thrombotic endocarditis may be a source of microembolic neoplastic spread leading to a possible pulmonary colonisation.

Meningitis due to Streptococcus bovis is rare. Only 14 cases having been reported in the English literature. All patients (including the patient described) had an underlying disease or were treated by pharmacological agents that predisposed the patient to the infection. Most were treated by monotherapy with penicillin G (or amoxicillin) and recovered. We describe a 74-year-old woman who had splenectomy as treatment for hairy cell leukemia 6 months before hospitalization for meningitis and sepsis by S. bovis type II. She was successfully treated with intravenous amoxicillin. There was neither evidence of endocarditis nor carcinoma of the colon. Although the association between S. bovis meningitis and endocarditis or carcinoma of the gastrointestinal tract is not well established, we recommend a full work-up for GI malignancy and endocarditis in every patient with S. bovis meningitis.

We present three cases of so-called mesothelial/monocytic incidental cardiac excrescences (MICE) of the heart and a brief review of related literature. Case 1 was a 51-year-old woman who underwent mitral- and aortic-valve replacement. A tissue sample was submitted as a thrombus attached to the left atrial endocardium. Case 2 was a 69-year-old woman who underwent mitral-valve replacement. The sample was incidentally obtained as whitish clot-like fragments, but its exact origin was not known. Case 3 was a 68-year-old woman who underwent mitral-valve replacement for suspected infective endocarditis. The sample adherent to the pericardium was removed after valvular surgery. Histologically, these lesions were composed of a mixture of plump histiocytoid cells, a papillary arrangement of cuboidal cells, various sized vacuoles, and fibrin. The nests of cuboidal cells resembled cancer cells but showed features of mesothelial cells and no proliferative activity, immunohistochemically or ultrastructurally. In all cases, a suction tube placed in the left atrium was occasionally used to remove overflowing intrapericardial fluid during the surgery. The tip of the suction tube was covered with spiral wire, which is likely to transfer the stripped pericardial mesothelial cells to the left atrium. The significance of MICE is their possibility of being misdiagnosed as metastatic carcinoma by pathologists and a risk of arterial embolization by mesothelial debris clinically.

Aspiration of oro-pharyngeal secretions and gastric content is the most frequent cause of formation of primary lung abscess. A compromised mental status (e.g. alcoholism, sedatives, stroke) and esophageal dysfunction (e.g. herniation, vomiting) are important risk factors. Aspiration pneumonia presents as a subacute disease and is usually not distinguishable from other causes of pneumonia, until typical radiological signs of cavitation and putrid sputum appear 8 to 14 days after the initial event of aspiration. Anaerobic bacteria play a pivotal role in an almost exclusively mixed spectrum of causative organisms. Aerobic pathogens are also frequently isolated, but whether they are an active part of infection or merely represent colonizers remains unclear in many instances. Differential diagnosis includes bronchial neoplasms, either as necrotizing carcinoma or as the cause of poststenotic cavernous pneumonia, other infectious diseases like tuberculosis, Pneumocystis carinii pneumonia or endocarditis with septic metastases, and lung artery embolism or vasculitis (M. Wegener). Fiberoptic bronchoscopy is extremely helpful in determining cause and etiology of the disease and should be carried out in all patients presenting with cavernous lung lesions. Bacteriological sampling should be performed using protected specimen brushing (PSB) technique. Broncho-alveolar lavage might serve as a less expensive but also less sensitive alternative measure. Since anaerobic bacteria resemble ubiquitous commensals of the oral cavity, sputum is of no use in anaerobic culture. Principal therapeutic strategy is antibiotic therapy for an extended period, usually four weeks to four months, unless radiologic changes and as well laboratory as clinical indicators of infection are completely resolved. Clindamycin, optionally supplemented with a second or third generation cephalosporin and Ampicillin/Sulbactam proved equally effective in treating aspiration pneumonia and primary lung abscess. The role of Moxifloxacin and other new flouroquinolones with their favorable pharmacodynamics is currently evaluated. Provided that antibiotics are prescribed for a sufficient period of time and patients' compliance is ensured, surgical procedures are limited to a negligible number of complications, e.g. recurrent severe hemoptysis, empyema or broncho-pleural fistula.

A 63-year-old man presented with cachexia and confusion. He was found to have culture-negative endocarditis affecting his aortic valve. Despite treatment with broad-spectrum antibiotics and extensive investigation for an underlying cause, he suffered a large cerebral infarct and died. At post-mortem he was found to have non-bacterial thrombotic endocarditis and a metastatic signet-ring carcinoma.

This paper reviews the literature and discusses patient selection for endosseous dental implants and the effect of systemic and local pathology on the success rate of dental implants. Endosseous dental implants may be preferable to conventional dentures in patients with compromised supporting bone or mucosa, xerostomia, allergy to denture materials, severe gag reflex, susceptibility to candidiasis, diseases affecting orofacial motor function or in patients who demand optimal bite force, esthetics, and phonetics. Conventional dentures or fixed partial prostheses may be preferable to endosseous dental implants in growing and epileptic patients and patients at risk of oral carcinoma, anaphylaxis, severe hemorrhage, steroid crisis, endocarditis, osteoradionecrosis, myocardial infarction, or peri-implantitis. A systematic approach to dental implant patient selection is outlined and centralized reporting of dental implant outcomes is recommended.

A 77-year-old man presented to our hospital with a clinical scenario suspicious for endocarditis with septic emboli to the lungs and splenic abscess. Vibrio cholerae was isolated from purulent material aspirated from the abscess. Medical therapy and percutaneous drainage of the abscess were unsuccessful. The patient underwent splenectomy and distal pancreatectomy revealing a pancreatic tail carcinoma involving the spleen and colon. The patient later expired secondary to metastatic disease. This case represents the first isolation of V. cholerae from a splenic abscess but also illustrates that although newer imaging technologies have made the diagnosis of splenic abscess easier, the true etiology of the abscess may remain elusive.
