1/231. 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 = 1keywords = infection (Clic here for more details about this article) |
2/231. actinomycosis of the central nervous system: surgical treatment of three cases.Three cases of actinomycotic brain infection are described, 2 of which manifested as cerebral abscess, the third as epidural empyema. Complete resolution of the infection was always achieved by means of surgical treatment and prolonged antibiotic therapy. The cases reported emphasize the importance of a combined approach in the treatment of this unusual cause of brain infection.- - - - - - - - - - ranking = 0.5keywords = infection (Clic here for more details about this article) |
3/231. actinomycosis--an unusual case of an uncommon disease.actinomycosis is an uncommon disease caused by organisms of the actinomyces genus. These organisms are commonly found in the mucous membranes but do not cause infection unless there is disruption of the membranes, as occurs, for example, during dental trauma or abdominal surgery. Use of an IUD is also a risk factor for pelvic actinomycosis. The disease is usually insidious and is often mistaken for other conditions. Treatment of the infection, once diagnosed, is a regimen of long-term antibiotics such as penicillin, clindamycin, and others. Our patient had pelvic and sacral actinomycosis without any of the traditional risk factors for infection.- - - - - - - - - - ranking = 0.5keywords = infection (Clic here for more details about this article) |
4/231. 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 = 0.16666666666667keywords = infection (Clic here for more details about this article) |
5/231. 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 = 0.16666666666667keywords = infection (Clic here for more details about this article) |
6/231. 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 = 0.66666666666667keywords = infection (Clic here for more details about this article) |
7/231. Lacrimal canaliculitis.Lacrimal canaliculitis is an infection of the lacrimal duct system. The classic features of lacrimal canaliculitis are mild to severe swelling of the canaliculus, mucopurulent discharge from the punctum, and a red, pouting punctum. Canaliculotomy with systemic or topical antibiotics is the most appropriate treatment for this disorder.- - - - - - - - - - ranking = 0.16666666666667keywords = infection (Clic here for more details about this article) |
8/231. 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 = 0.16666666666667keywords = infection (Clic here for more details about this article) |
9/231. Misleading diagnosis of retroperitoneal actinomycosis.A 34-year-old woman presented with a left-sided suprarenal space-occupying lesion on sonography. culture of material obtained during sonographic-guided puncture of the retroperitoneal lesion yielded a mixed flora of actinomyces and peptostreptococcus. Initially, a misleading diagnosis of an adrenal pheochromocytoma was initiated by highly positive metaiodobenzylguanidine scintigraphy after chemical chemistry vanillylmandelic acid (VMA) test showed elevated values for adrenaline and its derivatives. Retroperitoneal actinomycosis with yet unproven spread into thoracic and cervical compartments is a particular unusual presentation of an infection with these organisms. Because it may mimic subacute infections or malignant masses in terms of clinical and laboratory findings, radiological diagnosis of this entity may be difficult. The diagnosis was based on results of culture and the response of the patient to long-term penicillin-derivate therapy after surgical drainage of the suprarenal abscess formation.- - - - - - - - - - ranking = 0.33333333333333keywords = infection (Clic here for more details about this article) |
10/231. Cranial epidural empyema with osteomyelitis caused by actinomyces, CT, and MRI appearance.actinomycosis is an uncommon cause of intracranial infection. Epidural empyema represents about 6% of CNS actinomycotic lesions. A case of an epidural empyema with parietal bone osteomyelitis caused by actinomyces israelii is presented. Relevant neuroimaging features were bone erosions and a multiloculated collection with annular contrast enhancing on CT. Postoperative MRI revealed extensive involvement of the neighbor dura, falx, and subdural space. MRI was crucial to follow-up the response to antibiotic treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = infection (Clic here for more details about this article) |
