1/6. actinomyces as a cause of recurrent perianal fistula in the immunocompromised patient.actinomycosis is an uncommon bacterial infection that has a characteristic chronic indolent course. patients with this infection frequently undergo multiple surgical procedures before a correct diagnosis is made. Perianal actinomycosis should be suspected if a nontender perianal mass is found to contain thin purulent material and small yellow particles (sulfur granules). The diagnosis is confirmed by special stains and anaerobic cultures. Recognition of this infection is important because successful treatment requires combined surgical and antibiotic therapy. We report two patients, one with diabetes mellitus and one with human immunodeficiency virus III, who had recurrent perianal abscesses caused by actinomyces and were treated successfully with surgical drainage and antimicrobial therapy.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/6. scalp actinomycosis mimicking soft tissue mass.actinomycosis is a rare, subacute or chronic bacterial infection, characterized by localized swelling with suppuration, abscess formation, tissue fibrosis, and draining sinuses. It is caused by gram-positive, pleomorphic non-spore-forming, non-acid-fast anaerobic or microaerophilic bacilli of the genus actinomyces. In humans, actinomyces are often normally found in the oral cavity, the gastrointestinal tract and the female genital tract. Infections of the oral and cervicofacial regions are the most commonly reported cases. We present a case of subcutaneous actinomycosis, localized at the upper segment of the posterior neck space, with scalp involvement.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
3/6. Primary intracranial actinomycosis. Report of a case and review of the literature.actinomycosis is a bacterial infection that affects chiefly the cervico-oro-facial area, the abdomen and lungs. From these sites it may sometimes spread to the central nervous system. Extremely rare, and controversial, is the possibility of a primary infection of the central nervous system. We report an odd case of apparently primary brain abscess caused by actinomyces israeli and review the literature.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
4/6. actinomycosis meningitis in a girl with incontinentia pigmenti.A 7-year-old girl with incontinentia pigmenti and a history of multiple bacterial infections developed chronic meningitis with actinomycosis odontolyticus, which was successfully treated with long-term penicillin administration. Although all tests of immunologic function were normal in this patient, her history of recurrent and unusual infections is consistent with previous suggestions of an undefined immunodeficiency state associated with incontinentia pigmenti.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
5/6. Unusual manifestations of thoracic actinomycosis.actinomycosis is a chronic, suppurative bacterial infection characterized by multiple abscesses, sinus tracts, fibrosis, and granulation involving the face, neck, thorax, or abdomen. Thoracic actinomycosis probably results from aspiration of oropharyngeal secretions. Its description in the literature is extensive. Reported herein are two cases of thoracic actinomycosis with unusual manifestations exemplifying the organism's lack of regard for fascial planes. The authors present a comprehensive review of actinomycosis in order to encourage early diagnosis. The importance of bedside examination and inspection of available material stained by Gram's method are emphasized. Computed tomography scanning is a useful adjunct for assessing the anatomic extent of this disease.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
6/6. Pulmonary actinomycosis appearing as a "ball-in-hole" on chest radiography and bronchoscopy.A 40 year old diabetic man with pulmonary actinomycosis was admitted to hospital with recurrent haemoptysis. The chest radiograph showed an air meniscus in the left upper lobe, a rare presentation of pulmonary actinomycosis. Bronchoscopic examination revealed a mass in a cavity which has never been reported previously. He underwent lobectomy and the surgical specimen revealed sulphur granules, the typical pathological finding of actinomycosis, without evidence of fungal or mycobacterial infection.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
