1/322. endocarditis caused by actinomyces viscosus.A case of severe endocarditis caused by actinomyces viscosus is described in a previously healthy 70-year-old man. The isolated strain has been characterized by biochemical tests, gas-liquid chromatography and serology. The pathogenic significance of the organism is discussed and the difficulty in reaching a correct diagnosis due to the similarity to species of corynebacterium is pointed out.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
2/322. Actinomyces and nocardia infections in immunocompromised and nonimmunocompromised patients.A retrospective survey of nocardia and actinomyces infections in five local hospitals was conducted over a 3-year period in El Paso, texas, a border city, in the southwestern united states. The medical records of 42 patients with suspected nocardiosis or actinomycosis were reviewed. One patient was diagnosed with actinomyces and 12 patients with nocardia. Microbiological data included morphologic characteristics, biochemical profile, and susceptibility testing. Predisposing factors included leukemia, renal insufficiency, renal transplant, and lymphoma. No predisposing factors were found in 67% (n = 8) of patients (including the patient with actinomycosis). Twenty-three percent (n = 3) of patients had disseminated disease without evidence of underlying disease or immunosuppression. The mortality and morbidity of these infections appeared to be low.- - - - - - - - - - ranking = 2keywords = ear (Clic here for more details about this article) |
3/322. Hepatic actinomycosis. A case report.A case of hepatic actinomycosis contracted one year after removal of an intrauterine device during ongoing Actinomyces cervicitis is reported. During active disease, lymphocytes from the apparently fully immunocompetent patient were able to proliferate but not to produce the proinflammatory lymphokine gamma-interferon in response to Actinomyces antigen. This ability was only partly restored during antibiotic therapy.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
4/322. Urinary undiversion for pelvic actinomycosis: a long-term follow up.BACKGROUND: A 43-year-old woman who had been using intrauterine contraceptive devices for the past 10 years underwent an emergency operation for bowel and urinary obstruction. methods/RESULTS: Frozen section analysis showed undifferentiated adenocarcinoma. Incomplete tumorectomy, ileal resection, partial cystectomy, colostomy and bilateral ureterocutaneostomy were palliatively performed. Postoperatively, periodic acid-Schiff and Grocott-Gomori methenamine tests revealed Actinomyces and the final diagnosis was pelvic actinomycosis. Treatment with penicillin g administered intravenously relieved her symptoms and the lesion was dramatically improved. The patient underwent colostomy closure and urinary undiversion. CONCLUSIONS: Five years after urinary undiversion, the patient's renal function has been maintained and she can void without incontinence and dysuria.- - - - - - - - - - ranking = 3keywords = ear (Clic here for more details about this article) |
5/322. pilonidal sinus of the penis. A report of two cases, one of them associated with actinomycosis.pilonidal sinus is a long-standing chronic inflammatory condition which occurs most commonly in the sacrococcygeal area and it is rare in the penis. Two cases of penile pilonidal sinus in patients aged 25 and 28 years are reported and the literature is reviewed. The lesion is acquired and has to be distinguished from balanoposthitis, epidermal cyst and carcinoma. For pilonidal sinus to occur at this site, it is hypothesized that the coronal sulcus acts as a cleft where hair may accumulate and be driven into the shaft and prepuce by the natural movement between these two surfaces. One of our cases was associated with actinomycosis. actinomycosis associated with pilonidal sinus of the penis is extremely rare and there are only two previous reports. It is suggested that pilonidal sinus may have been predisposed to the infection with the actinomyces organisms. Information stating that penile pilonidal sinus and actinomycosis may occur simultaneously is necessary to accomplish an early diagnosis.- - - - - - - - - - ranking = 2keywords = ear (Clic here for more details about this article) |
6/322. actinomyces viscosus postoperative endophthalmitis.endophthalmitis, attributable to actinomyces viscosus, developed in a 78-year-old man after cataract surgery. Postoperative endophthalmitis with this organism is a rare occurrence. This report emphasizes the importance of the Actinomyces species as potential eye pathogens and presents antimicrobial susceptibility data for the isolate.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
7/322. Endobronchial actinomycosis simulating endobronchial tuberculosis: a case report.We report a case of a 70-year-old woman who presented with mild exertional dyspnea and cough. Fiberoptic bronchoscopic findings revealed an endobronchial polypoid lesion with stenotic bronchus. The lesion was very similar to endobronchial tuberculosis. Histologic examination of the biopsy specimen demonstrated Actinomyces infection. There was a clinical response to intravenous penicillin therapy. Primary endobronchial actinomycosis must be considered in the differential diagnosis of an endobronchial lesion, especially endobronchial tuberculosis in korea.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
8/322. Synovial actinomycosis of the hip: case report and review.A case of hematogenous spread of an actinomycotic granule to the left hip joint is presented. This occurred in a 62-year-old woman under immunosuppressive treatment for Wegener's disease. It was a chance finding on routine synovium biopsy during a total hip replacement. Treatment consisted of 1 g ampicillin I.M. a day for six weeks. The postoperative course was uneventful.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
9/322. actinomycosis: a potential complication of head and neck surgery.actinomycosis is a granulomatous infection occasionally found in the head and neck region that potentially may complicate a major head and neck oncologic surgical procedure. A case presentation, a review of the pertinent literature, and the treatment of this infectious complication are the primary elements of this report. A chronic infection of the neck caused by Actinomyces ssp developed postoperatively in a patient treated for head and neck cancer. Despite relapse after an initial course of long-term antibiotic therapy, the infection was successfully eradicated. actinomycosis after surgery for head and neck cancer is unusual. However, the etiologic agent, Actinomyces ssp, is a common, potential microbial contaminant of head and neck surgery characterized by oral cavity or pharyngeal entry. Recognition of the typical manifestation of this infection in the neck facilitates prompt, appropriate treatment.- - - - - - - - - - ranking = 10.42017404881keywords = cancer (Clic here for more details about this article) |
10/322. Pelvic actinomycosis.Pelvic actinomycosis is a rare chronic infection caused by bacteria of the family actinomycetaceae. Prolonged use of an intrauterine contraceptive device (IUD) is a well known risk factor. We report six patients with pelvic actinomycosis, all of whom had an IUD inserted for over six years. Diagnostic problems necessitated a laparotomy in all patients. The pathohistological diagnosis was based on the characteristic microscopic image and specific staining. The patients were treated with penicillin and amoxycillin for several months.- - - - - - - - - - ranking = 1keywords = ear (Clic here for more details about this article) |
