1/27. Second-trimester abortion caused by capnocytophaga sputigena: case report.Intra-amniotic infection is often the cause of a second-trimester abortion. The bacterial species involved include bacteria with low pathogenicity like ureaplasma urealyticum and various mycoplasma species. In this case we describe an intra-amniotic infection caused by capnocytophaga sputigena, often found in the normal bacterial flora of the oral cavity, but not in the vagina. Oral sex during pregnancy was the most probable source of the infection. The aborted fetus showed signs of pneumonia upon histologic examination. The bacterial species was identified using broad-spectrum 16S rDNA polymerase chain reaction (PCR) directly from the amniotic fluid and after bacterial culture. amniotic fluid glucose was below detection level, confirming the presence of an intra-amniotic infection.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/27. Purulent pericarditis presenting as an extracardiac mass in a patient with untreated diabetes.A 50-year-old man with symptoms of bi-ventricular heart failure was transferred to our hospital with a diagnosis of extracardiac tumor. He had a 10 year history of untreated diabetes. Chest computed tomography (CT) revealed an extracardiac mass in the right atrio-ventricular groove. cardiac catheterization revealed an elevated mean right atrial pressure of 18 mmHg, mean pulmonary wedge pressure of 16 mmHg, and the right ventricular pressure curve demonstrated typical dips and plateaus. At surgery, there was severe adhesion between the pericardium and epicardium, and the pericardium was severely thickened and contained turbid pus. In the left thoracic cavity, there was large amount of pleural effusion and pus. Therefore, the patient was diagnosed with purulent pericarditis caused by left empyema. The thickened pericardium at the anterior portion of the heart was resected, however resection of the remaining portion was abandoned because the adhesion was so tight. After surgery, the patient underwent irrigation of the heart and left thoracic cavity by 1% povidone iodine solution and 0.5 mg/ml of imipenem for 7 days. Bacteriologic culture of the pus from the pericardium revealed anaerobic gram negative bacteria. After 4 months of antibiotics infusion, his C reactive protein became negative and the patient was subsequently discharged from our hospital.- - - - - - - - - - ranking = 0.057978680631364keywords = cavity (Clic here for more details about this article) |
3/27. eikenella corrodens prosthetic valve endocarditis in a patient with ulcerative colitis.A 33-y-old male with ulcerative colitis developed prosthetic valve endocarditis (PVE) caused by eikenella corrodens. The outcome of conservative treatment was successful. Only 2 cases of E. corrodens PVE were found in a survey of the English-language medical literature. In contrast to previous data indicating that eikenella infections usually derive from the oral cavity, our patient most likely acquired the infection by colonoscopy and mucosal biopsies, which were performed a few days before onset of the disease.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/27. veillonella parvula meningitis: case report and review of veillonella infections.veillonella parvula is a small, nonfermentative anaerobic gram-negative coccus that is part of the normal flora of the mouth, gastrointestinal tract, and vagina in humans. When isolated from clinical specimens, V. parvula is often regarded as a contaminant or commensal, but it has been implicated as a pathogen in infections of the sinuses, lungs, heart, bone, and central nervous system. meningitis, however, is extremely rare; to our knowledge, only 2 cases have been previously described in the literature. We report a case of V. parvula meningitis and review the literature on veillonella infections.- - - - - - - - - - ranking = 0.036251237253096keywords = mouth (Clic here for more details about this article) |
5/27. capnocytophaga cynodegmi cellulitis, bacteremia, and pneumonitis in a diabetic man.capnocytophaga cynodegmi (formerly "DF-2 like organism"), a commensal organism of the canine oral cavity, is a capnophilic, gram-negative, facultative bacillus. C. cynodegmi has rarely been encountered in human diseases. We report the first known case of cellulitis, bacteremia, and pneumonitis caused by C. cynodegmi in a diabetic man from central india following a dog bite.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
6/27. Diffuse crescentic glomerulonephritis in bacterial endocarditis.Renal involvement is common in patients with bacterial endocarditis. The most common bacteria are staphylococci and streptococci, and the commonest renal histopathological lesion is a diffuse proliferative and exudative type of glomerulonephritis. Very rarely, patients may present with an extensive glomerular epithelial crescent formation with a rapid deterioration in the renal function. This study reviews the published literature on diffuse crescentic glomerulonephritis in bacterial endocarditis and reports a 24-year-old male patient with endocarditis due to Capnocytophagia species, a gramnegative facultative anaerobic bacillus, which normally inhabits the oral cavity. Appropriate antibiotic therapy is essential to eradicate the infection. A brief course of corticosteroid therapy may be helpful in those with deteriorating renal function. plasmapheresis may be useful in those with persistent hypocomplementemia, increased circulating immune complexes, and a progressive deterioration in the renal function. Removal of vegetation or valve replacement may be necessary. prognosis is generally good.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
7/27. capnocytophaga canimorsus endophthalmitis following cataract surgery.An elderly man developed endophthalmitis 1 week after cataract extraction and lens implantation. Intraocular samples were collected and the patient received intravitreal vanco-mycin and ceftazidime, and topical tobramycin. A Gram stain of vitreous humour revealed spindle-shaped Gram-negative bacilli. He was then given systemic clindamycin and topical ofloxacin. capnocytophaga canimorsus, a member of the oral flora of dogs and cats, was cultured after 3 days. The infection resolved leaving the patient with a visual acuity of 6/60. An attempt was made to culture the organism from the mouth of the patient's pet dog. This was unsuccessful and the source of the infection remains unknown.- - - - - - - - - - ranking = 0.036251237253096keywords = mouth (Clic here for more details about this article) |
8/27. eikenella corrodens brain abscess after repeated periodontal manipulations cured with imipenem and neurosurgery.eikenella corrodens is a facultatively anaerobic gram-negative rod that colonizes the oral cavity and very rarely produces central nervous system (CNS) infections. frontal lobe abscesses are occasionally associated with a dental source of infection. We report a case of an adult man with overzealous dental cleaning habits who developed a right frontal brain abscess caused by E. corrodens. He underwent neurosurgical drainage of the pus and was successfully treated with imipenem 4 g/i.v./day for 4 weeks with no complications. Repeated periodontal trauma could explain the Eikenella brain abscess in this case.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
9/27. eikenella corrodens discitis after spinal surgery: case report and literature review.eikenella corrodens is part of the normal flora of the mouth and upper respiratory tract and is usually associated with dental and head and neck infections. We report a case of Eikenella discitis occurring soon after spinal surgery in an otherwise healthy patient, review the literature on bone and joint infections unrelated to human bites and fist-fight injuries, and stress the importance of definitive diagnosis in post-operative spinal infections.- - - - - - - - - - ranking = 0.036251237253096keywords = mouth (Clic here for more details about this article) |
10/27. capnocytophaga gingivalis bacteremia detected only on quantitative blood cultures in a child with leukemia.capnocytophaga species are inhabitants of the normal mouth flora. We describe the case of a 6-year-old-girl with leukemia and poor oral hygiene who developed bacteremia caused by capnocytophaga gingivalis. The organism was detected only on quantitative blood cultures.- - - - - - - - - - ranking = 0.036251237253096keywords = mouth (Clic here for more details about this article) |
