1/33. 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 = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/33. uterine perforation with Lippes loop intrauterine device-associated actinomycosis: a case report and review of the literature.A case of a 67-year-old postmenopausal woman, gravida 2, para 2, with an uterine perforation from actinomycotic infection with Lippes loop IUD is reported. She had the Lippes loop IUD inserted for 35 years, and had never had any pelvic examination nor Papanicolaou smear. She presented with acute abdominal pain. The clinical picture mimicked peptic ulcer perforation. The woman underwent laparotomy and exudative fluid was discovered in the abdominal cavity with the tip of the Lippes loop IUD at one of the two small holes of the uterine fundus. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The postoperative microscopic pathological report demonstrated characteristics of actinomycosis. She was treated with parenteral high-dose penicillin for 4 weeks followed by oral penicillin for 6 months. The woman had an uneventful recovery. To our knowledge, this is the first case report of uterine perforation due to Lippes loop IUD-associated actinomycotic infection.- - - - - - - - - - ranking = 0.051764482036317keywords = cavity (Clic here for more details about this article) |
3/33. A case of endobronchial actinomycosis.actinomycosis is an infectious disease caused by certain actinomyces species. actinomyces are Gram-positive, non-spore forming organisms characterized by obligate or facultative anaerobic rods that normally inhabit anaerobic niches of the human oral cavity. Cervicofacial, abdominal, pelvic and thoracic infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. Endobronchial actinomycosis can be misdiagnosed as unresolving pneumonia, endobronchial lipoma or malignancies. Endobronchial actinomycosis should be included in the differential diagnosis of any endobronchial mass. We report a case of a 43-year-old man who presented with a productive cough and pulmonary consolidation at the right lower lobe on chest radiograph. Fiberoptic bronchoscopy revealed obstruction of the right superior segment of the lower bronchus with an exophytic endobronchial mass. Endobronchial actinomycosis was confirmed by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of penicillin g followed by oral amoxacillin/clavulanic acid therapy for 3 months resulted in improving symptoms. Infiltrative consolidation on the chest X-ray was markedly decreased.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/33. Rothia dentocariosa endocarditis complicated by multiple intracranial hemorrhages.Rothia dentocariosa is a gram-positive rod found commonly as part of the normal flora of the mouth. It rarely causes clinical disease. Subacute infective endocarditis has been the most commonly reported R dentocariosa infection, and extracardiac complications occur frequently. Solitary intracranial hemorrhages have been reported in two cases. We describe the first case of infective endocarditis complicated by the sequential and unusually prolonged development of multiple new intracranial hemorrhages.- - - - - - - - - - ranking = 0.030375053915924keywords = mouth (Clic here for more details about this article) |
5/33. Ureteral and sigmoid obstruction caused by pelvic actinomycosis in an intrauterine contraceptive device user.We report herein a rare case of ureteral and sigmoid obstruction caused by pelvic actinomycosis in a patient fitted with an intrauterine contraceptive device (IUCD). A 63-year-old Japanese woman was admitted complaining of lower abdominal pain and slight fever continuing for a month. She had a history of IUCD insertion 30 years previously and had been menopausal for the past 10 years. ultrasonography and CT scan revealed a solid pelvic mass involving the uterus, sigmoid colon, urinary bladder, and right ureter. The IUCD was detected in the uterine cavity. Right hydronephrosis and hydroureter due to an obstruction of the distal ureter and the extensive stenosis of the sigmoid colon were also observed. blood analysis showed leukocytosis, thrombocytosis, and elevated c-reactive protein levels. Although pathological and microbiological analysis of the removed IUCD showed negative results for actinomyces infection, these findings suggested a pelvic abscess caused by actinomycosis. Benzyl penicillin administration was started immediately. Total hysterectomy, bilateral salpingo-oophorectomy, and lysis of adhesion around the ureter were performed. actinomycosis was diagnosed based on histologic examination. The patient's postoperative course was uneventful except for persistent mild hydroureter and hydronephrosis. The patient is now healthy without evidence of recurrent actinomyces infection 1 year after treatment. As shown in the present case, pelvic actinomycosis should be considered as a cause of pelvic inflammatory disease in IUCD users, even though actinomyces was not detected on the IUCD.- - - - - - - - - - ranking = 0.051764482036317keywords = cavity (Clic here for more details about this article) |

7/33. Soft-tissue abscess involving actinomyces odontolyticus and two Prevotella species in an intravenous drug abuser.skin and soft-tissue infections in intravenous users comprise a variety of microorganisms and anaerobic bacteria are frequently involved in these suppurative infections. A case of subcutaneous abscess into anterior femoral muscles involving actinomyces odontolyticus and two Prevotella species (Prevotella buccae and prevotella melaninogenica) in an intravenous drug abuser is presented. This combination of microorganisms has not previously been described in soft-tissue infections. The patient volunteering that he licked his hypodermic needle prior to cocaine injection supports that the implicating bacteria originated from the oral cavity. Eventually, the patient recovered and at a 6-month follow-up a gradual improvement of his subcutaneous infection was noticed.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
8/33. Retroperitoneal actinomycosis due to dropped gallstones.Dropped bile and gallstones after accidental perforation of the biliary gallbladder is a frequent event during laparoscopic cholecystectomy and is generally of no clinical importance. However, calculi left in the abdominal cavity can produce a series of severe late complications. We present a patient with retroperitoneal actinomycosis produced by dropped gallstones after a laparoscopic cholecystectomy.- - - - - - - - - - ranking = 0.051764482036317keywords = cavity (Clic here for more details about this article) |
9/33. actinomycosis of the temporal bone: a report of a case.actinomycosis is a chronic suppurative infection of the cervicofacial region caused by actinomyces species, which are anaerobic, gram-positive filamentous bacteria. Although actinomycosis has a propensity for involving the oral cavity, rare cases of actinomycosis involving the temporal bone have been published. We report the case of a 14-year-old girl who presented with clinical, audiometric, and radiologic findings consistent with right chronic suppurative otitis media that persisted despite tympanomastoidectomy. Findings on histologic evaluation of a specimen obtained during revision surgery were consistent with a diagnosis of actinomycosis. Although actinomycosis of the temporal bone is rare, it should be considered in the differential diagnosis of chronic suppurative temporal bone infections that are resistant to standard therapy.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
10/33. actinomycosis of the middle turbinate: an unusual cause of nasal obstruction.actinomycosis is a rare chronic infectious disease caused by actinomyces israelii, which is an anaerobic filamentous, gram-positive saprophyte organism of the oral cavity. Historically, these bacteria were known as fungi because of their light microscopic appearance. actinomycosis consists of three different forms: cervico-facial (the most common form), abdominal and pulmonothoracic. It commonly involves the head and neck region including the mandible, paranasal sinuses, lacrimal gland, parotid gland and orbit. Poor oral hygiene and dental diseases have been known to be the source of actinomycosis. actinomycosis is diagnosed with positive culture or detecting actinomyces colonies and sulfur granules in histopathologic specimens. The treatment of choice is surgical excision of the lesion and long-term penicillin therapy. actinomycosis of the internal nose is extremely rare. There was only one nasal septum actinomycosis reported in the English literature, but there was no lateral nasal wall actiomycosis regarding the turbinate. Therefore, actinomycosis should not be overlooked for the differential diagnosis of intra-nasal lesions for the initiation of appropriate and early treatment.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
