    Full Text Available Introduction. Actinomycosis is a chronic bacterial infection caused by Actinomyces, Gram-positive anaerobic bacteria. Its symptomatology imitates some malignant pelvic tumours, tuberculosis, or nocardiosis, causing abscesses and fistulas. Actinomycoses are opportunistic infections and require normal mucous barriers to be altered. No epidemiological studies have been conducted to determine prevalence or incidence of such infections. Objective. To analyse the clinical cases of pelvic actinomycosis reported worldwide, to update the information about the disease. Methods. A systematic review of worldwide pelvic actinomycosis cases between 1980 and 2014 was performed, utilising the PubMed, Scopus, and Google Scholar databases. The following information was analysed: year, country, type of study, number of cases, use of intrauterine device (IUD, final and initial diagnosis, and method of diagnosis. Results. 63 articles met the search criteria, of which 55 reported clinical cases and 8 reported cross-sectional studies. Conclusions. Pelvic actinomycosis is confusing to diagnose and should be considered in the differential diagnosis of pelvic chronic inflammatory lesions. It is commonly diagnosed through a histological report, obtained after a surgery subsequent to an erroneous initial diagnosis. A bacterial culture in anaerobic medium could be useful for the diagnosis but requires a controlled technique and should be performed using specialised equipment.

    Actinomycosis is an infectious disease that appears throught the world, in cattle and human beings. It is a chronic granulomatous and suppurative lesion, usually affecting the cervicofacial area. Definitive diagnosis, by culture or biopsy, is not always possible, so the clinician must suspect it by its clinical presentation. It is the purpose of this article to present the patients diagnosed and treated in our Department during the last 5 years, and to review the ideal therapy.

    Full Text Available Actinomycotic infection of the female genital tract is rare. Actinomycosis is a chronic suppurative granulomatous infection that is characterized by formation of abscesses, multiple draining sinuses and appearance of tangled mycelial masses or granules in the discharges and tissue sections. 2 cases of tubo-ovarian actinomycosis are reported. The 1st case presented clinical with gastrointestinal symptoms and a ventral scar hernia following an operation for a non-healing abdominal wound 6 months earlier. The 2nd case sought medical attention for backache and leucorrhea of 4 years′ duration. Exploratory laparotomy in the 1st case revealed tubo-ovarian masses; the vermiform appendix was not traceable. The uterine cavity in the 2nd case harbored a wooden stick. Direct extension from established ileocacal actinomycosis was believed to involve the female genital adnexae in the past. Association of tubo-ovarian actinomycosis with the presence of a foreign body in the female genital tract has been reported sporadically in the literature, yet an increase in the incidence may be expected because of the frequent use of intrauterine contraceptive devices in recent times. It is suggested that in women presenting clinically with vague abdominal symptoms, backache and discharge, actinomycosis should be considered and ruled out with the help of cytologic and proper microbial culture methods. Once the diagnosis is established, the infection can be treated with good results with penicillin.

    Intestinal actinomycosis: a case report. The authors describe a case of intestinal actinomycosis, which was manisfestated by abdominal mass and suggested, clinical and radiologically, a bowel carcinoma. They discuss the pathogenesis, and the clinical and radiological manisfestations of this disease, and its differential diagnosis. This is an infrequent disease which must be considered whenever suggestive clinical aspects are associated with a radiological ''malignant pattern'' of a bowel lesion. (author) [pt

    Abdominal actinomycosis is a chronic, progressive, suppurative disease with a favorable response to intravenous treatment with penicillin. In many instances, however, its clinical and radiological findings may overlap with those of other inflammatory and neoplastic conditions, and the familiarity with the various radiological features can thus avoid diagnostic delays. The purpose of this paper is to describe and discuss the CT findings of abdominal actinomycosis

    Conclusions: Actinomycosis should be considered in the differential diagnosis of abdominal or pelvic malignancies in women who have used an intrauterine device for contraception. Although treatment usually consists of surgical resection of the affected area due to preoperative diagnostic difficulty, we suggest using a less invasive procedure, such as small piece-incision biopsy and an immediate frozen pathology to avoid the potential risk of overtreatment and unnecessary complications.

    Full Text Available PRESENTATION OF CASE Actinomycetes are branching gram-positive anaerobic bacteria belonging to Actinomycetaceae family and are commensals in human oropharynx, gastrointestinal tract and female genitalia. Thoracic or pulmonary actinomycosis is an uncommon bacterial infection. The diagnosis of pulmonary or thoracic actinomycosis is often confounding because of its shared clinical features with malignant lung diseases and chronic suppurative lung diseases. However, chest physicians should be aware of actinomycosis being a differential diagnosis in persistent shadows in lung as early diagnosis leads to good prognosis. 1

    Full Text Available A 27 year old patient presented a swollen lesion in the right mandibular area. Prior to the visit the patient was diagnosed with acne and was treated for 6 consecutive months with oral limecycline with no positive response. During the visit the cervicofacial actinomycosis was diagnosed and the patient was administered treatment containing oral amoxycilin plus clavulanic acid among others. The skin lesion disappeared within three weeks. The authors discuss this case in spite of diagnostic difficulties of this uncommon condition, especially while differentiating from acne conglobata.

    Full Text Available Actinomycosis is a chronic infection caused by Actinomyces israelii, usually seen in immunocompromised patients or in the background of tissue injury. Cervicofacial actinomycosis presenting as a fixed jaw swelling in an elderly individual can mimic malignancy and pose a diagnostic dilemma. We report here a case of cervicofacial actinomycosis diagnosed by fine needle aspiration, along with a review of the relevant literature. A 60 year-old man presented with a gradually increasing 6 x 5 cm swelling in the left side of his jaw. The swelling was fixed, without any apparent sinus or abscess. Fine needle aspiration was diagnostic as it revealed colonies of actinomyces surrounded by polymorphs and chronic inflammatory cells. The histopathological study of the excised specimen confirmed the cytological findings. Fine needle aspiration is an effective tool in the diagnosis of actinomycosis although its documentation is rare. Difficulties in the management can be avoided by early diagnosis using the fine needle aspiration technique.

    Full Text Available Abstract Introduction Actinomyces are slow growing, non-spore forming, gram-positive, branching bacilli that thrive in anaerobic and microareophilic conditions. Actinomyces are more commonly associated with oral and cervicofacial infections. Hepatic involvement in infections of the abdomen (known as isolated hepatic actinomycosis is rare, accounting for only 5% of all cases of actinomycosis. Case presentation We present the case of a 75-year-old Caucasian woman with a 3-month history of night sweats, fever, chills, abdominal bloating, anorexia, weight-loss, and early satiety. The patient was found to have isolated hepatic actinomycosis infection after undergoing a laparotomy with a biopsy of the liver. The patient has now recovered. Conclusion Isolated hepatic actinomycosis is a rare and often overlooked etiology for a liver mass. Given its subacute presentation and nondescript symptomatology, physicians should be aware of this differential and the potential pitfalls in diagnosis and management.

    1999-07-01

    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. (orig.)

    Actinomycosis is a chronic suppurative infection with bacteria of the Actinomycetaceae family, characterized by the formation of abundant granular tissue and multiple abscesses. It is a rare entity, and clinical and radiological findings are similar to those in other inflammatory and in neoplastic processes. Actinomycosis should be considered in the differential diagnosis in high-risk patients with predisposing factors, such as alcoholism, poor oral hygiene, maxillofacial trauma, tuberculosis, chronic obstructive pulmonary disease, steroid ingestion or immunodeficiency, and in patients in whom the disease history does not correlate with widespread metastatic involvement. Early diagnosis is important, to prevent disease progression and unnecessary surgery, since the response to drug treatment is very good. We present a case of diffuse actinomycosis involving multiple organs (liver, kidneys, colon, and lungs) that simulated metastatic disease on radiography and computed tomography (CT). (author)

    Actinomycosis is a chronic granulomatous disease caused by Gram-positive anaerobic bacteria of the genus Actinomyces. Pulmonary actinomycosis is a rare infection in children, and its extension into the chest wall is infrequently reported. We report a case of pulmonary actinomycosis in a 14-year-old girl of Mapuche descent who presented with chronic respiratory symptoms and multiple discharging skin sinuses on her right lower chest wall. The diagnosis was made by skin biopsy, which showed sulfur granules with actinomyces colonies. She was successfully treated with intravenous ceftriaxone and penicillin G for 6 weeks, followed by oral amoxicillin for 6 months. © 2013 Wiley Periodicals, Inc.

    Full Text Available Hepatosplenic abscess caused by Actinomyces is rare and often misdiagnosed as malignancy. Herein, we report a case of hepatosplenic actinomycosis in a 37-year-old immunocompetent man with a 2-month clinical history of intermittent fever and upper left abdominal pain. Physical examination revealed a mildly ill-appearing man with a low-grade fever (38°C and upper left quadrant abdominal tenderness. Abdominal sonographic examination showed the presence of a 6.3 cm × 6.5 cm heterogeneous abscess with a hypoechoic center and honeycomb appearance in an enlarged spleen (8 cm × 5 cm. Computerized tomography of the abdomen revealed a multiloculated splenic lesion, and laparotomy showed multiple hepatic nodules and a splenic abscess. Histopathological examination of the biopsy revealed filamentous branching bacilli and sulfur granules in the hepatosplenic abscess. The patient successfully underwent splenectomy accompanied by intravenous and oral penicillin treatment. Proper and prompt diagnosis of hepatosplenic actinomycosis is important because the therapeutic plan and prognosis of this pathogen are quite different from other microorganisms and malignancies.

    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

    Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. A 46-year-old female presented with recurrent throbbing pain on the right first and second molar of the mandible three weeks after root planing. Exploratory flap surgery was performed, and the bluish-gray tissue fragment found in the interproximal area between the two molars was sent for histopathology. The diagnosis from the biopsy was actinomycosis. The clinical and radiographic manifestations of this case were clinically indistinguishable from periodontitis. The patient did not report any symptoms, and she is scheduled for a follow-up visit. The present study has identified periodontitis-mimicking actinomycosis. Actinomycosis should be included in the differential diagnosis in cases with periodontal pain and inflammation that do not respond to nonsurgical treatment for periodontitis. More routine submissions of tissue removed from the oral cavity for biopsies may be beneficial for differential diagnosis.

    Actinomycosis is a rare suppurative disease that may mimic other inflammatory conditions on imaging. Its invasive nature may lead to mass formation and atypical presentation thus making accurate diagnosis quite difficult. To describe the different aspects of abdominopelvic actinomycosis on cross-sectional imaging and indicate discriminative findings from other inflammatory or neoplastic diseases. In our study we analyzed 18 patients (15 women, 3 men; age range, 25–75 years; mean age, 50 years) with pathologically proved abdominopelvic actinomycosis. Contrast-enhanced abdominal computed tomography (CT) had been performed in all patients. Eleven patients had a history of using intrauterine contraceptive devices. Bowel site, wall thickness and enhancement degree, inflammatory infiltration, and features of peritoneal or pelvic mass were evaluated at CT. The sigmoid colon was most commonly involved. Most patients showed concentric bowel wall-thickening, enhancing homogenously and inflammatory infiltration of pericolonic fat was mostly diffuse. In 11 patients, one or more pelvic abscesses were revealed, while a peritoneal or pelvic mass adjacent to the involved bowel segment was seen in three cases. Infiltration into the abdominal wall was seen in three cases while in one case there was thoracic dissemination. Actinomycosis is related not only to long-term use of intrauterine contraceptive devices and should be included in the differential diagnosis when cross-sectional imaging studies show concentric bowel wall-thickening, intense contrast enhancement, regional pelvic or peritoneal masses, and extensive inflammatory fat infiltration with abscess formation

    Full Text Available Actinomycosis is a chronic infectious granulomatous disease caused by saprophytic Actinomyces species. The case discussed in this report is of an adult female patient with a large actinomycotic lesion in the region of the mandibular left second premolar, first and second molars. Provisional diagnosis was made as extragingival pyogenic granuloma. Definitive diagnosis was based on histopathological examination. Since actinomycotic infection has opportunistic characteristics, early diagnosis and proper management of the disease is mandatory to prevent further complications.

    F. de Clerck

    2015-01-01

    Full Text Available Introduction. Pancreatic actinomycosis is a chronic infection of the pancreas caused by the suppurative Gram-positive bacterium Actinomyces. It has mostly been described in patients following repeated main pancreatic duct stenting in the context of chronic pancreatitis or following pancreatic surgery. This type of pancreatitis is often erroneously interpreted as pancreatic malignancy due to the specific invasive characteristics of Actinomyces. Case. A 64-year-old male with a history of chronic pancreatitis and repeated main pancreatic duct stenting presented with weight loss, fever, night sweats, and abdominal pain. CT imaging revealed a mass in the pancreatic tail, invading the surrounding tissue and resulting in splenic vein thrombosis. Resectable pancreatic cancer was suspected, and pancreatic tail resection was performed. Postoperative findings revealed pancreatic actinomycosis instead of neoplasia. Conclusion. Pancreatic actinomycosis is a rare type of infectious pancreatitis that should be included in the differential diagnosis when a pancreatic mass is discovered in a patient with chronic pancreatitis and prior main pancreatic duct stenting. Our case emphasizes the importance of pursuing a histomorphological confirmation.

    Abdominal wall Actinomycosis is a rare disease associated with the use of intrauterine device and as a complication of abdominal surgery. Diagnosis is difficult because it is unusual and behaves like a malignant neoplasm. A case report is presented of a patient who had used an intrauterine device for four years and developed a stony tumour in the abdominal wall associated with a set of symptoms that, clinically and radiologically, was simulating a peritoneal carcinomatosis associated with paraneoplastic syndrome, even in the course of an exploratory laparotomy. The patient attended our hospital with a two-month history of abdominal pain and symptoms that mimic a paraneoplastic syndrome. The diagnosis of abdominal actinomycosis was suspected by the finding of the microorganism in cervical cytology together with other cultures and Actinomyces negative in pathological studies, confirming the suspicion of a complete cure with empirical treatment with penicillin. Actinomycosis should be considered in patients with pelvic mass or abdominal wall mass that mimics a malignancy. Antibiotic therapy is the first treatment choice and makes a more invasive surgical management unnecessary. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

    Actinomycosis is a chronic suppurative granulomatous disease caused by Actinomyces israelii. Preoperative confirmed diagnosis is very difficult, so most cases are diagnosed preoperatively as malignant tumors. We report a case of intraabdominal actinomycosis which was difficult to diagnose preoperatively. A woman, 60 years old, experienced discomfort in her lower right abdomen. She complained of nausea and anorexia and visited our hospital. Laboratory blood tests, abdominal CT, and abdominal MRI led to a diagnosis of a uterine sarcoma or primary intestinal mass, and she underwent surgery. Her histopathological diagnosis was intraabdominal actinomycosis. Actinomycosis is a chronic purulent granulomatous inflammation caused by Actinomyces israelii. No clinical symptoms or laboratory findings are characteristic of abdominal actinomycosis, so this disorder is very difficult to diagnose preoperatively. Therefore, many cases are diagnosed as malignant tumors and undergo surgery. After surgery, long-term antibiotic treatment (penicillin) is usually administered. We reported a case of intraabdominal actinomycosis that resulted in a difficult to diagnose intraperitoneal mass. When a large intraperitoneal mass is found, actinomycosis needs to be included as one of differential diagnoses. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Actinomyces are gram-positive aerobic-growing bacteria that are part of human bacterial flora. Actinomyces infections, which are more prevalent among men than among women (3:1), usually affect patients in their fourth decade and most often involve A. israelli (85%). thoracic, abdominal or pelvic actinomycosis is uncommon. Pulmonary infections result more from aspiration of oral secretions than from direct extension. We report one case of necrotizing pneumonia of a patient with previous stab wound injury in the affected hemi thorax and an unusual aggressive behavior

The swelling was nodular, fixed, and nonulcerated, with multiple healed and few active discharging sinus tracts draining serosanguineous fluid and yellowish sulfur granules. FNA was diagnostic, as it revealed colonies of Actinomyces surrounded by polymorphs. Histopathology of excised specimen confirmed the cytological findings. FNA is an effective tool in the diagnosis of actinomycosis, although, its documentation is rare. Difficulties in the management can be avoided by early diagnosis using the FNA technique.

    The actinomycosis is a suppurative infection due to an anaerobic and microaerophillic bacteria called actinomyces. Only few case reports are described for the mediastinal locations of this rare entity. We report a new case of inflammatory pseudotumor in the mediastinum due to Aggregatibacte actinomycetemcomitans revealed by hemoptysis. The mediastinoscopy procedure with biopsy was needed to confirm the definitive bacteriological diagnosis by a positive culture. During the postoperative course, a cutaneous fistula was found which had a favourable evolution after appropriate antibiotherapy. Through this case report, the authors insist upon the importance of considering the diagnosis of mediastinal actinomycosis when facing non-specfic mediastinal mass symptoms and also about the interest of systematic bacterioscopic examination and histopathologic examination on nodes' biopsies to avoid to be lost on pathology of mediastinal tumor or tuberculosis. In practise, we caution the non-expert during biopsies because of this lesion's invasive characteristic especially in the confined space of the mediastinum. Copyright © 2016 Elsevier Masson SAS.

    2014-12-01

    Conclusion: Pelvic actinomycosis should always be considered in patients with a pelvic mass and peritoneal infiltration, especially in the presence of intrauterine device use, despite the fact that abundant ascites, pleural effusion, and lymphadenopathy almost never accompany pelvic actinomycosis. Endometrial/endocervical biopsy may yield a diagnosis without an invasive procedure and should be performed. Because of the excellent response to penicillin, medical treatment alone is an effective method to eradicate pelvic actinomycosis without the need for surgical intervention.

  19. Dual pathology: cervicofacial actinomycosis and nicorandil-induced oral ulceration.

    2008-04-01

    Oral ulceration has many causes and is a common presenting symptom in otolaryngology. This article presents an unusual case of dual pathology oral ulceration in an elderly patient. Oral malignancy was initially suspected, but the history, examination and investigation showed that the oral ulceration was caused by actinomycosis infection and by nicorandil use. Cervicofacial acinomycosis is a rare, suppurative bacterial disease in which abscesses can form in the tissues and break through the skin, creating pus-discharging lesions. Nicorandil is a potassium channel blocker used in the treatment of ischaemic heart disease. It has been recently recognised as a cause of persistent ulcerative stomatitis. This case highlights the importance of a high index of suspicion for unusual and reversible causes of oral ulceration, and of dual pathology as a cause. Such vigilance enables early recognition and treatment of potentially reversible conditions.

    Full Text Available Actinomycosis infection is a slow progressing disease, in which involvment of the central nervous system by Actinomyces israelii is uncommon (less than 5%. Clinical picture is non-specific and is often misdiagnosed with neoplasia; some clinical clues my arise suspicion. The case of a 59 year-old female is reported who presented headache and focal neurologic signs and in whom a out-of the hospital diagnosis of a neuroepitelial dysembryoplastic tumor was made; nonetheless after careful interview and physical exploration, a spectroscopy magnetic resonance of the brain and hystopathological description of the lesion was made and yielded the definitive diagnosis of intracranial actinomyces infection. Treatment and progression were uneventful.

    Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle. A ctinomycosis is a chronic suppurative and granulomatous disease that is characterized by the formation of multiple abscesses, draining sinuses, abundant granulation and dense fibrous tissue. The disease is most frequently caused by Actinomyces israelii. These organisms are gram-positive anaerobic bacteria, and are considered opportunistic pathogens associated with infection, trauma or surgery. These events allow them to cross mucosal barriers as these organisms are normally present in healthy individuals, especially in the oral cavity, gastrointestinal tract, and female genital tract. In abdominopelvic actinomycosis, aggressive perilesional infiltration with a tendency to cross fascial planes or boundaries and extend to the abdominal wall has been well described as an important radiologic finding. Actinomycosis of the gallbladder is an extremely rare disease; only 21 cases have been reported in the English literature. Moreover, a diagnosis of actinomycosis of the gallbladder is difficult because this condition can be confused with carcinoma. We report here on a rare case of actinomycosis of the gallbladder that presented as a mass by sonography and computed tomography (CT)

    Widespread use of antibiotics facilitates the development of some uncommon chronic infections such as actinomycosis. The clinical and radiographic findings overlap those of other inflammatory and neoplastic conditions. With a review of the literature, we report the CT and MRI findings in a case of thoracic actinomycosis, presenting with right ventricular failure caused by heart involvement. CT was helpful in identifying the mediastinal extent of the disease and in demonstrating the absence of pulmonary involvement. MRI, however, offered complementary information, especially in assessing heart involvement without the need for intravenous contrast media. On T2-weighted images the mediastinal process was noted to be of relatively low signal intensity, possibly indicating its benign nature. The association with heart involvement was suggestive of thoracic actinomycosis. (orig.)

    Full Text Available Actinomycosis is a chronic granulomatous suppurative infection caused by anaerobic bacteria from genus Actinomyces which are normal flora of mouth, colon and vagina. Actinomycosis of upper extremity is rare. We report a case of actinomycosis of the distal phalanx of finger many years after flap reconstruction. The patient presented with two months’ history of chronic discharging sinus from the tip of his right index finger, which had sustained a degloving injury 20 years previously. It had been treated with an anterior chest wall flap which had healed uneventfully but was bulky due to excess tissue from the donor site. Radiograph revealed osetomyelitis changes of distal phalanx. Debulking surgery with curettage of the distal phalanx was done. Wound healing was uneventful. He was treated with six weeks of metronidazole and ciprofloxacin. The discharge from the distal phalanx cultured actinomycosis odontolyticus. Histopathology of the debrided tissue showed chronic inflammation. As far as we are aware, there are no reports of actinomycosis in a flap involving the finger treated previously with a chest wall skin flap. The infection was probably dormant for many years before manifesting as a discharging sinus. Although the finger flap was bulky, it was not problematic until it started to have serous discharge. With a thorough debridement of all infected tissue, six weeks of antibiotic was adequate. Ciprofloxacin was prescribed based on discharge culture sensitivity. Metronidazole was added as actinomycosis is anaerobic. Response was prompt as patient was not immunocompromised. At follow-up six months post-surgery the finger had recovered with good function. If not for the discharging sinus, patient would probably have tolerated his bulky finger for the rest of his life.

    Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.

    Full Text Available Background: Primary actinomycosis of the anterior abdominal wall and appendix are very rare clinical entities. An accurate diagnosis is generally obtained by histological examination, and treatment often requires surgical resection. Case Report: In this study we presented two cases of primary actinomycosis involving the anterior abdominal wall and a third one located in the appendix. Conclusion: Actinomyces Israelii can involve all anatomic structures of the abdomen. Although preoperative diagnosis is difficult, the combination of surgery and antibiotic treatment results in complete treatment in the majority of cases.

    Full Text Available Actinomycosis often manifests with abscesses in the cervicofacial region. Hepatic involvement occurs usually secondary to an intraabdominal infection. “Isolated or primary hepatic actinomycosis (PHA defines actinomycosis in which the source of infection cannot be demonstrated elsewhere. Herein, we aimed to highlight hepatic actinomycosis in the differential diagnosis of hepatic mass lesions, and also its occurrence even in patients without underlying risk factors. A 24-year-old man, who presented with epigastric and right-upper-quadrant abdominal pain, fever, weight loss, and had a tumor-like mass in the liver was admitted to our hospital. He had no predisposing risk factors or comorbidities. We reviewed all the cases with PHA, who had no predisposing risk factors, in English medical literature from 1993 to 2014. Actinomycotic hepatic pseudotumors should be considered in the differential diagnosis of solitary liver lesions even in patients without any predisposing factors.

    To investigate the value of the computed tomography (CT) in the study of diagnostic and post-treatment findings of pulmonary actinomycosis. Clinical data and CT findings were retrospectively analyzed in 10 patients with histopathologically confirmed pulmonary actinomycosis. We analyzed the initial CT findings in search of patterns and distributions which suggest possible lung abnormalities and found the pleura, chest wall, and lymphadenopathy to be involved as part of the indicators of lung abnormalities. We analyzed follow-up CT findings for changes in the lungs after antibiotic therapy and recurrence after surgery. Of the 10 patients analyzed by CT for lung lesions, seven had been diagnosed with alcoholism and nine were male. The initial CTs (n = 10) indicated that all the pulmonary lesions were solitary without chest wall involvement. However, a transfissural extension was observed in 20% of the study population (n = 2). Furthermore, peripheral lung distribution and adjacent pleural thickening was observed in 70% of the study population (n = 7). Within the consolidation (n = 6) or mass (n = 4), a central low density with peripheral enhancement was seen in 70% of the study population (n = 7). A follow-up CT of the seven cases following antiobiotic therapy revealed that four cases showed minimal improvement or aggravation of their lung lesions, whereas three cases showed resolution or improvement. The improvement of the central low density was related to the improvement of consolidation or mass. Furthermore the presence of fibrosis was observed after the resolution of pulmonary lesions (n = 2). No relationship was found between the duration and response of antibiotic therapy. A follow-up CT (n = 4) subsequent to a lung resection revealed the onset of chest wall actinomycosis and a thickened pleura in one case. The results of this study highlight the value of the CT in pulmonary actinomycosis in order to diagnose and evaluate antibiotic responses, complications, or

    Intrabdominal actinomycosis is difficult to diagnose preoperatively. This chronic infection has a propensity to mimic many other diseases and may present with a wide variety of symptoms. The aim of this study was to evaluate the characteristic clinical features with review of the literature. We retrospectively analyzed 22 patients with intrabdominal actinomycosis between January 2000 and January 2006. There were two men and 20 women with a mean age of 42.8 years (range, 24-69). Twelve patients presented with masses or abdominal pain, whereas 3 patients presented with acute appendicitis. The rate of performing an emergency surgery was 50% due to symptoms of peritonitis. The mean size of tumor was 5.5 cm (range, 2.5-11.0). Sixty percent (n = 12) of female patients had intrauterine device (IUD). The average time to definite diagnosis was 10.6 days. Intrabdominal abdominal actinomycosis must first be suspected in any women with a history of current or recent IUD use who presents abdominal pain. If recognized preoperatively, a limited surgical procedure, may spare the patient from an extensive operation.

    2017-01-01

    Full Text Available We report a rare case of lung abscess due to Eubacterium brachy. In this case, an analysis of the aspirate from frank pus revealed Gram-positive coccobacilli. We initially strongly suspected lung abscess associated with actinomycosis because of the chronic/recurrent clinical course and radio-pathological findings such as a granuloma lesion. Although a biochemical analysis revealed Actinomyces sp., 16S rRNA gene sequencing and a phylogenetic tree analysis of the isolated strain confirmed the presence of E. brachy. Some cases previously diagnosed as actinomycosis might be correctly diagnosed as E. brachy infection. Clinicians should be aware that additional studies using 16S rRNA gene sequencing are needed to clarify whether pulmonary infection associated with E. brachy is a similar entity to that of chronic granulomatous infection disease in pulmonary actinomycosis.

    2010-01-01

    Full Text Available We report a rare case of orbital swelling presenting one year after head trauma. An initial fine needle aspiration cytology revealed it to be an infected organizing hematoma. However, broad-spectrum antibiotics did not resolve the infection and the orbital lesion continued to grow in size, as evaluated by magnetic resonance imaging. Incisional biopsies were done, which were reported as orbital actinomycosis. Patient has responded well to treatment with penicillin. This case is of interest due to the delayed presentation of an orbital complication of head trauma and the rare infection with actinomyces. It also highlights the importance of using appropriate antibiotics, as well as the need for long-term treatment.

    In this report a case of actinomycosis in a five-month-old Holstein calf is described. The patient displayed a hard and immobile swelling in the mandible and fever. Computed tomography (CT) imaging of the skull was performed under deep sedation and revealed an asymmetrical appearance of the mandible with the presence of intra-mandibular hypodense lesions. Haematologic and serum biochemical profiles revealed leukocytosis, neutrophilia, hypoalbuminaemia and hypergammaglobulinaemia. Treatment consisted of flushing the lesion and administration of antibiotics and non-steroidal anti-inflammatory drugs. The calf responded to therapy and had recovered almost completely four months later. The present case indicates that CT is an effective non-invasive means of identifying mandibular lesions in cattle

    2007-11-01

    Full Text Available Abstract Pelvic actinomycosis is a rare disease that can result in abscess formation, bowel obstruction, and other serious complications. Moreover, the correct diagnosis can seldom be established before radical surgery because the disease often mimics pelvic neoplasms. It has been recently recognized that pelvic actinomycosis is associated with long-term use of an intrauterine contraceptive device. We report a woman with a long-standing intrauterine contraceptive device who visited our hospital complaining of symptoms mimicking large bowel ileus with a subacute course. X-ray fluorography and sigmoidoscopy showed marked stenosis in the sigmoid colon but rejected the possibility of colon cancers. Abdomino-pelvic CT and MRI revealed a huge abscess lying over the urinary bladder and anterior to the uterus. Furthermore, a cervical Papanicolaou smear disclosed Actinomyces species. We removed the intrauterine device from the patient. Subsequent high-dose ampicillin administration led to dramatic shrinkage of the abscess and improved the management of the bowel movement quickly. This is a successful case of symptomatic pelvic actinomycosis that was correctly diagnosed and treated without unnecessary surgical intervention.

    Abdominal actinomycosis is a rare infection caused by Actinomyces, a grampositive bacterium that generally exists as a saprophyte in the oral cavity and colon. The diagnosis is usually difficult due to its low incidence and nonspecific clinical and radiological findings. We present three new cases of abdominal actinomycosis. The first involved several pelvic structures and abdominal wall. The second was detected in left hepatic lobe. In the third case, the infection was located in descending colon. We stress the wide range of presenting signs, describing the findings that, when taken together, suggest the correct diagnosis. (Author) 13 refs.

    Full Text Available En el presente artículo se actualizan los conocimientos sobre actinomicosis y se presenta el caso de un niño con la forma torácica de dicha entidad. La actinomicosis es una infección infrecuente que puede afectar cualquier parte del cuerpo; los Actinomyces son bacilos o filamentos gram positivos que forman parte de la flora endógena de las mucosas en especial las de las cavidades oral e intestinal. Su comportamiento es insidioso pero en oportunidades tiene expresión aguda, fistulización a piel y cicatrización con fibrosis. Los llamados gránulos de azufre son una característica macroscópica del exudado que contribuye al diagnóstico de laboratorio. La infección inicial para la forma cervicofacial suele provenir de la cavidad oral y extenderse a la vecindad o ser aspirada a los pulmones. El tratamiento de elección es la penicilina, inicialmente endovenosa y seguidamente oral por un lapso no menor de 6 meses. Algunas formas requieren manejo quirúrgico. We report the case of a child with thoracic actinomycosis and review this disease. Actinomycosis is a rare infection that can affect any part of the body; Actinomyces are gram positive bacilli or filaments belonging to the endogenous flora of the mUCOUS membranes, specially that of the oral cavity and the intestinal tract. Actinomycosis usually behaves as an insidioUS disease but may ocassionally have acute expressions with fistulization to the skin and fibroUS healing during resolution. The So called sulfur granules are an important macroscopic detail that helps establish the diagnosis. Actinomyces infections usually start in the oral cavity for the cervicofacial form and then spread to contiguous tissues or to the lungs via aspiration. Penicillin is the drug of choice and surgical drainage may become necessary.

    1994-07-01

    The most common infectious cause of bilateral upper-lobe pulmonary disease is tuberculosis. However, we recently encountered a patient with bilateral apical infiltrates and multiple soft-tissue abscesses caused by Actinomyces odontolyticus. Other findings included fever, weight loss, and leukocytosis, and the patient's only known source of immunosuppression was a long history of alcoholism. There was no history of diabetes, steroid use, or other chronic underlying disease. The diagnosis was made by culture of drainage fluid from one abscess. Therapy with intravenous penicillin G led to rapid clinical improvement and reduction in the infiltrates. To our knowledge, the presentation of pulmonary infection, with bilateral apical infiltrates due to A. odontolyticus has not been previously reported in the medical literature.

    2015-01-01

    Actinomycosis is a chronic infection caused by Actinomyces species characterized by abscess formation, tissue fibrosis, and draining sinuses. The spectrum of infections caused by Actinomyces species ranges from classical invasive actinomycosis to a less invasive form of superficial skin and soft tissue infection. We present a review detailing all Actinomyces species isolated from breast infections in NHS Lothian between 2005 and 2013, Actinomyces species isolated from breast infections referred to the United Kingdom Anaerobe Reference Unit between 1988 and 2014, and cases describing Actinomyces breast infections published in the medical literature since 1994. Actinomyces species are fastidious organisms which can be difficult to identify and are likely to be underascertained as a cause of breast infections. Due to improved diagnostic methods, they are increasingly associated with chronic, recurrent breast infections and may play a more significant role in these infections than has previously been appreciated.

  17. Pilonidal Sinus of the Glans Penis Associated with Actinomyces Case Reports and Review of Literature

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available Pilonidal sinus is a well-recognized condition that occurs most commonly in the sacrococcygeal area of younger men. It is hypothesized to be an acquired chronic inflammation condition due mainly to hair trapped beneath the surface. A pilonidal sinus in the sacrococcygeal region is associated with recurrent infection, abscess formation, cellulitis, fistulae, and rarely, squamous cell carcinoma. A pilonidal sinus of the penis is a rare entity. The association of a penile pilonidal cyst and Actinomyces is even more uncommon with only three cases reported previously. Two cases of pilonidal sinus are reported in this paper. One of the cases was associated with actinomycosis. Pilonidal sinus of the penis should be considered in the clinical and pathological differential diagnosis and has to be distinguished from balanoposthitis, epidermal cyst, and carcinoma. The knowledge about possible association with actinomycosis is important to ensure early treatment.

    Full Text Available Pulmonary actinomycosis is a rare disease that is often misdiag-nosed as tuberculosis or lung cancer. Actinomyces graevenitzii is a relatively new recognized Actinomyces species isolated from various clinical samples. The authors report a case of pulmonary actinomycosis caused by A graevenitzii. A computed tomography examination revealed an excavated consolidation in the middle right lobe of a previously healthy young man who presented with a long history of moderate cough. Cultures of the bronchoalveolar lavage fluid confirmed the diagnosis of pulmonary abscess caused by A gravenitzii. At the three-month follow-up consultation and, after six weeks of high-dose amoxicillin, the pulmonary lesion had completely disappeared.

    Full Text Available Abstract Background Apart from neoplastic processes, chronic disfiguring and destructive diseases of the mandible are uncommon. Case Presentation We report, perhaps for the first time, the simultaneous occurrence of two such conditions in one patient, in a case that emphasizes the importance of bone biopsy in establishing the correct diagnosis. Florid cemento-osseous dysplasia (FCOD is a chronic, disfiguring condition of the maxillofacial region. This relatively benign disease is primarily observed in middle-aged women of African ancestry. Cervicofacial actinomycosis is an uncommon and progressive infection caused by bacilli of the Actinomyces genus that typically involves intraoral soft tissues but may also involve bone. The accurate diagnosis of actinomycosis is critical for successful treatment. A diagnosis of osteomyelitis caused by Actinomyces bacteria was diagnosed by bone biopsy in a 53 year-old African-American woman with a longstanding history of FCOD after she presented with a new draining ulcer overlying the mandible. Conclusions Clinicians should be aware of the possibility of actinomycosis arising in the setting of FCOD, and the importance of bone biopsy and cultures in arriving at a definitive and timely diagnosis.

  5. Radicular Cyst With Actinomycotic Infection in an Upper Anterior Tooth

    Directory of Open Access Journals (Sweden)

    Shuei-Kuen Tseng

    2009-10-01

    Full Text Available Actinomycosis is an infection caused by filamentous, branching, Gram-positive anaerobic bacteria. It rarely infects the jawbone. This case report describes a patient with a left maxillary central incisor with an apical lesion and actinomycotic infection. A 23-year-old male patient underwent conventional root canal treatment of tooth 21, in a local dental clinic for about 1 year. However, percussion pain and a sinus tract that originated from tooth 21 were still present after treatment. Nonsurgical root canal treatment of tooth 21 was performed again but failed to relieve the symptoms. Therefore, apicoectomy and retrograde filling of the apical root canal with mineral trioxide aggregate were carried out. Periradicular bony defect was grafted by biocompatible material, and postoperative antibiotics (250 mg amoxicillin were given three times daily for 5 days. Pathological examination of the removed periapical tissue showed a radicular cyst with actinomycosis. At the 9-month postoperative recall, the sinus tract had disappeared and radiographic examination showed healing of the apical lesion. Periradicular actinomycosis is one important reason for failure of nonsurgical endodontic treatment. Clinically, if the tooth shows a recurrent sinus tract and poor response to conventional root canal treatment combined with antibiotic control, apical actinomycotic infection should be highly suspected, and an alternative endodontic surgical approach is needed for successful treatment.

  6. Actinomycotic Osteomyelitis of Maxilla Presenting as Oroantral Fistula: A Rare Case Report

    Directory of Open Access Journals (Sweden)

    Ashalata Gannepalli

    2015-01-01

    Full Text Available Actinomycosis is a chronic granulomatous infection caused by Actinomyces species which may involve only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is relatively rare when compared to mandible. These are normal commensals and become pathogens when they gain entry into tissue layers and bone where they establish and maintain an anaerobic environment with extensive sclerosis and fibrosis. This infection spreads contiguously, frequently ignoring tissue planes and surrounding tissues or organ. The portal of entry may be pulpal, periodontal infection, and so forth which may lead to involvement of adjacent structures as pharynx, larynx, tonsils, and paranasal sinuses and has the propensity to damage extensively. Diagnosis is often delayed and is usually based on histopathology as they are cultured in fewer cases. The chronic clinical course without regional lymphadenopathy may be essential in diagnosis. The management of actinomycotic osteomyelitis is surgical debridement of necrotic tissue combined with antibiotics for 3–6 months. The primary actinomycosis arising within the maxilla with contiguous involvement of paranasal sinus with formation of oroantral fistula is rare. Hence, we present a 50-year-old female patient with chronic sclerosing osteomyelitis of maxilla which presented as oroantral fistula with suppurative and sclerotic features.

    Pneumonia caused by slow-growing bacteria is rare but sometimes severe. These infections share many similarities such as several differential diagnoses, difficulties to identify the pathogen, the importance of involving the microbiologist in the diagnostic investigation and the need for prolonged antibiotic treatment. However, major differences distinguish them: Nocardia and Rhodococcus infect mainly immunocompromised patients while actinomycosis also concerns immunocompetent patients; the severity of nocardioses is related to their hematogenous spread while locoregional extension by contiguity makes the gravity of actinomycosis. For these diseases, molecular diagnostic tools are essential, either to obtain a species identification and guide treatment in the case of nocardiosis or to confirm the diagnosis from a biological sample. Treatment of these infections is complex due to: (1) the limited data in the literature; (2) the need for prolonged treatment of several months; (3) the management of toxicities and drug interactions for the treatment of Nocardia and Rhodococcus. Close cooperation between pneumonologists, infectious disease specialists and microbiologists is essential for the management of these patients. Copyright © 2017 SPLF.

    Granulomatous disease in the thyroid gland has been linked to viral, bacterial and autoimmune etiologies. The most common granulomatous disease of the thyroid is subacute granulomatous thyroiditis, which is presumed to have a viral or post-viral inflammatory cause. Bacterial etiologies include tuberculosis, actinomycosis, and nocardiosis, but are extremely rare. Disseminated actinomycosis and nocardiosis more commonly affect organ-transplant patients with the highest susceptibility within the first year after transplant surgery. A 45-year-old African American male, who received his third kidney transplant for renal failure secondary to Alport Syndrome, presented with numerous subcutaneous nodules and diffuse muscle pain in the neck. Further workup revealed bilateral nodularity of the thyroid. Fine needle aspiration of these nodules demonstrated suppurative granulomatous thyroiditis. Subsequent right thyroid lobectomy showed granulomatous thyroiditis with filamentous micro-organisms, morphologically resembling Nocardia or Actinomyces. Disseminated granulomatous disease presenting in the thyroid is very rare, and typically afflicts immune-compromised patients. The overall clinical, cytologic and histologic picture of this patient strongly points to an infectious etiology, likely Nocardia, in the setting of recent organ transplantation within the last year. © 2017 by the Association of Clinical Scientists, Inc.

    Full Text Available Zoophilic species of human dermatophytoses, such as Trichophyton mentagrophytes are significantly rare. We present a case of a 42-year-old male who for 2 months had been unsuccessfully treated and then referred to hospital with suspected actinomycosis. Lesions on the skin on his neck, submandibular area, cheeks and groins were consistent with extremely painful, merging inflammatory tumours and infiltrations with the presence of numerous pustules in hair follicles that poured purulent contents forming into yellow crusts after compression. The treatment with terbinafine was successful. The final identification of the Trichopyton mentagrophytes var. granulosum strain was performed based on a microscopic assessment of the culture, and the result of species identification was confirmed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP analysis.

    Technetium-99m MIBI was developed as a myocardiac perfusion imagine agent and has been used effectively in the detection and post-therapeutic evaluation of various neoplasm such as thyroid, lung, bone and breast tumors. As an infrequent findings, Tc-99m MIBI agent has shown in non-neoplastic pulmonary conditions including fibroding alveolitis, pulmonary actinomycosis, active pulmonary sarcoidosis, pulmonary interstitial fibrosis in progressive systemic sclerosis and active osteomyelitis. In a recent report conducted by Cetin Oncel, Tc-99m MIBI imaging is an effective method in the detection and follow-up of pulmonary tuberculosis. We have also experienced Tc-99m-MIBI uptake in active pulmonary tuberculosis incidentally found in a patient with suspected proliferative villonodular synovitis of the left ankle.

    2002-01-01

    James Homer Wright (1869-1928), the eldest son of a Pittsburgh glass merchant, was educated in Baltimore and practiced pathology in Boston from 1893 until his death in 1928. In 1896, when not quite 27 years old, he assumed directorship of the newly founded Pathology Laboratory at the Massachusetts General Hospital, a post he held for the next 30 years. He is remembered eponymously by the blood cell stain that bears his name and the Homer Wright pseudorosettes of neuroblastoma, but he made many additional contributions to pathology. These include the following: determination of the cellular lineage of multiple myeloma, identification of the megakaryocyte as the cell of origin of blood platelets, recognition of the cell of origin of the neuroblastoma, demonstration of spirochetes in syphilitic aneurysms of the aorta, and clarification of misconceptions about actinomycosis. Additionally, Wright coauthored, with Dr. Frank B. Mallory, the book Pathological Technique, which was a staple of laboratories for >40 years and exemplifies Wright's wide-ranging interests in, and contributions to, practical aspects of pathology including staining, culture and frozen section techniques, photography, and development of the rotary microtome. He received Honorary Doctor of Science Degrees from Harvard University, the University of Maryland (his alma mater), and the University of Missouri. He was the recipient of the Gross prize in 1905 for his publication on actinomycosis and the Boylston Medical Prize in 1908 for his discovery of the origin of platelets, and he was inducted into the American Academy of Arts and Sciences in 1915. Although shy and somewhat austere in the workplace, a different side was shown by his anonymously sending flowers to a young Norwegian opera singer whom he subsequently married. The pathology laboratories of the Massachusetts General Hospital were named the "James Homer Wright Pathology Laboratories" in 1956. Today James Homer Wright is remembered and

    Full Text Available Abstract Background Cutaneous myiasis of the breast due to infestation by the larva of Cordylobia anthropophaga is rare. To the best of our knowledge, only one case has been reported in the English literature. This rarity calls for an awareness of its possibility as a cause of furuncular breast lesions, especially in areas where the C. anthropophaga (Tumbu fly is endemic or in patients returning from such areas. As it can be easily confused with other furuncular breast lesions (like tuberculosis, mycosis, actinomycosis, furunculosis, chronic breast abscess and fungating malignancies, this awareness is important to avoid misdiagnosis or delay in diagnosis. We present a case of furuncular breast myiasis due to the larvae of C. anthropophaga earlier misdiagnosed as mastitis in a patient living in tropical Africa (Nigeria where the Tumbu fly is endemic. Case presentation We report a 70 year old woman who presented with a week history of itchy multiple discharging sinuses of the right breast. The sinuses contained wriggling larvae of C. anthropophaga. Fourteen larvae were extracted from the breast and the sinuses healed quite well after the extraction. Conclusions Cutaneous myiasis of the breast is rare, hence, an awareness of its clinical features is necessary when a patient presents with furuncular skin lesions especially in endemic areas or people returning from such areas. Diagnosis is mainly clinical and lesions heal well after the extraction of the larvae. Preventive measures such as ironing after drying of dresses and a good personal hygiene are crucial in controlling C. anthropophaga infestation.

    Full Text Available "nAbstract: Actinomyces species are normal residents of the mouth cavity, gastrointestinal tract and female genital tract. The genus consists of gram-positive bacteria, strictly anaerobic or microaerophilic. The bacteria are opportunists with a low virulence potential that cause actinomycosis only when the normal mucosal barriers are disrupted. The main purpose of this study was the isolation of Actinomyces strains and determining of their role in periodontal diseases. The present study was carried out on 100 patients with periodontal diseases referred to the Periodontic Department of Faculty of Dentistry. The sampling was done in 6 months with isolation of oral Actinomyces from microbial plaque and periodontal pocket. The samples were selected based on the following criteria: periodontal plaque with deep pocket (>3 mm, no antibiotic therapy for a period of at least two weeks, and lack of systemic diseases. One strain of Actinomyces viscosus and two strains of Actinomyces naeslundii were isolated from the patients with gingivitis and periodontitis. Of the 100 patients with gingivitis and periodontitis, aged between 18-57 years old, 46% were males and 54% were females. The peak incidence of the diseases (35% was in the third age group (31-40 and the lowest incidence (10% was in the first age group (<20. Forty patients (40% complained of gingival disease and its bleeding with lower incidence of (42.5% in female.

    2015-04-13

    We describe the rare occurrence of an Actinomyces meyeri cerebral abscess in a 55-year-old woman following a dental extraction. This patient presented with a 2-day history of hemisensory loss, hyper-reflexia and retro-orbital headache, 7 days following a dental extraction for apical peridonitis. Neuroimaging showed a large left parietal abscess with surrounding empyema. The patient underwent craniotomy and drainage of the abscess. A. meyeri was cultured. Actinomycosis is a rare cause of cerebral abscess. The A. meyeri subtype is particularly rare, accounting for less than 1% of specimens. This case describes an unusually brief course of the disease, which is usually insidious. Parietal lobe involvement is unusual as cerebral abscesses usually have a predilection for the frontal and temporal regions of the brain. Although there are no randomised trials to guide therapy, current consensus is to use a prolonged course of intravenous antibiotics, followed by 6-12 months of oral therapy. 2015 BMJ Publishing Group Ltd.

    Our aim was to assess the feasibility of using leucocyte-rich and platelet-rich fibrin (L-PRF) for the treatment of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in a single group study. After treatment with L-PRF, the response of each patient was recorded 1 month and 4 months postoperatively. Further assessments were made of the site, stage, concentration of c-terminal crosslinked telopepide of type 1 collagen, and actinomycosis. Among the total of 34 patients, 26 (77%) showed complete resolution, 6 (18%) had delayed resolution, and 2 (6%) showed no resolution. There was a significant association between the response to treatment and the stage of BRONJ (p=0.002) but no other significant associations were detected. This study has shown that it is feasible to use L-PRF for the treatment of BRONJ, but the effectiveness cannot be judged with this study design. Randomised prospective trials are needed to confirm this. Copyright © 2014 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

Purulence exited from the punctum lacrimale due to inflammation of the inferior canaliculus (canaliculitis. When pressure was applied to the mass, a second exit of purulence was also observed under the palpebral conjunctiva below the lacrimal caruncle. A surgical excision was performed followed by administration of local antibiotic therapy. The histopathological examination of the extracted mass revealed the existence of actinomycosis. Conclusion. Persistent or recurrent infections and lumps of the eyelids should be thoroughly investigated. Actinomyces as a causative agent should be considered. Differential diagnosis is broad and should include canaliculitis, chalazion, and multiple types of neoplasias. For this reason, in nonconclusive cases, a histopathological examination should be performed.

  17. On the causes of persistent apical periodontitis: a review.

    Apical periodontitis is a chronic inflammatory disorder of periradicular tissues caused by aetiological agents of endodontic origin. Persistent apical periodontitis occurs when root canal treatment of apical periodontitis has not adequately eliminated intraradicular infection. Problems that lead to persistent apical periodontitis include: inadequate aseptic control, poor access cavity design, missed canals, inadequate instrumentation, debridement and leaking temporary or permanent restorations. Even when the most stringent procedures are followed, apical periodontitis may still persist as asymptomatic radiolucencies, because of the complexity of the root canal system formed by the main and accessory canals, their ramifications and anastomoses where residual infection can persist. Further, there are extraradicular factors -- located within the inflamed periapical tissue -- that can interfere with post-treatment healing of apical periodontitis. The causes of apical periodontitis persisting after root canal treatment have not been well characterized. During the 1990s, a series of investigations have shown that there are six biological factors that lead to asymptomatic radiolucencies persisting after root canal treatment. These are: (i) intraradicular infection persisting in the complex apical root canal system; (ii) extraradicular infection, generally in the form of periapical actinomycosis; (iii) extruded root canal filling or other exogenous materials that cause a foreign body reaction; (iv) accumulation of endogenous cholesterol crystals that irritate periapical tissues; (v) true cystic lesions, and (vi) scar tissue healing of the lesion. This article provides a comprehensive overview of the causative factors of non-resolving periapical lesions that are seen as asymptomatic radiolucencies post-treatment.

    All the spectrum is encompassed of those miscellaneous pathologic entities occurring in the mammary stroma which are on record up to date other than "mixed fibroepithelial" tumors (fibroadenomas and phyllodes tumors) and tumors both "pure" and "mixed" originating from myoepithelium (adenomyoepitheliomas and pleomorphic adenomas). Also they were excluded those dysreactive-autoimmune diseases (sarcoidosis, sclerosing lymphocytic lobulitis, lobular granulomatous mastitis) and those inflammatory-infectious conditions (tuberculosis, actinomycosis, foreign body reactions, Mondor's disease) which can mimick breast tumors clinically or on image analysis, but on the contrary not evoking the idea of a tumor on histology. Specifically, inflammatory pseudotumor, myofibroblastoma, leiomyoma, neurinoma/neurofibroma, benign fibrous histiocytoma, hemangiopericytoma, fibromatosis, nodular fascitis, variants of lipoma, mesenchymoma, amartoma and its variants, hemangiomas, pseudoangiomatous hyperplasia of stroma, amyloid tumor, granular cell tumor, are consecutively described and discussed, with a large list of references enclosed to each rubric. Most of the pictures are taken from personally observed lesions of the breast. Only few pictures referred to are from their analogue lesions which occurred in soft parts of other locations, with specific mention of that when it was the case. Of note after reviewing the literature the fact that no glomus tumor, nor Kaposi's sarcoma either sporadic or in the context of any immunodeficiency, nor myelolipoma has been recorded yet.

    Background Tyrannosaurus rex and other tyrannosaurid fossils often display multiple, smooth-edged full-thickness erosive lesions on the mandible, either unilaterally or bilaterally. The cause of these lesions in the Tyrannosaurus rex specimen FMNH PR2081 (known informally by the name ‘Sue’) has previously been attributed to actinomycosis, a bacterial bone infection, or bite wounds from other tyrannosaurids. Methodology/Principal Findings We conducted an extensive survey of tyrannosaurid specimens and identified ten individuals with full-thickness erosive lesions. These lesions were described, measured and photographed for comparison with one another. We also conducted an extensive survey of related archosaurs for similar lesions. We show here that these lesions are consistent with those caused by an avian parasitic infection called trichomonosis, which causes similar abnormalities on the mandible of modern birds, in particular raptors. Conclusions/Significance This finding represents the first evidence for the ancient evolutionary origin of an avian transmissible disease in non-avian theropod dinosaurs. It also provides a valuable insight into the palaeobiology of these now extinct animals. Based on the frequency with which these lesions occur, we hypothesize that tyrannosaurids were commonly infected by a Trichomonas gallinae-like protozoan. For tyrannosaurid populations, the only non-avian dinosaur group that show trichomonosis-type lesions, it is likely that the disease became endemic and spread as a result of antagonistic intraspecific behavior, consumption of prey infected by a Trichomonas gallinae-like protozoan and possibly even cannibalism. The severity of trichomonosis-related lesions in specimens such as Tyrannosaurus rex FMNH PR2081 and Tyrannosaurus rex MOR 980, strongly suggests that these animals died as a direct result of this disease, mostly likely through starvation.

    We report a case of radiation-induced skin ulcer, cerebral meningioma, and skin cancer in a 69-year-old woman who had undergone local irradiation and application of radium directly to the skin for actinomycosis of the face at the age of twenty. Some forty to fifty years later, a skin ulcer in the preauricular area in the center of the radiodermatitis, cerebral meningioma in the right sphenoid ridge, and a keratotic skin tumor in the right auricle all developed within the previously irradiated region. The cerebral meningioma was extirpated. The skin ulcer was excised and covered with a forearm flap. After the skin tumor was excised and the subcutaneous tumor in the postauricular area was excised, the postoperative histopathological diagnosis was squamous cell carcinoma with lymph node metastasis. It was considered that the squamous cell carcinoma was derived from irradiated keratosis. Four months later, right neck lymph node dissection was performed. Both the meningioma and squamous cell carcinoma satisfied Cahan's criteria for radiation-induced tumors. So we diagnosed these as radiation-induced cerebral meningioma and squamous cell carcinoma. We haven't detected any recurrence of the squamous cell carcinoma for two years. We learned from this case that chronic radiation disturbances cause an irreversible reaction and various radiolesions, including malignancies, can occur after a long period of latency. It is important to never underestimate a small lesion in the irradiated area, to plan early preventive surgical treatment to remove skin that may have been over-subjected to irradiation, and to continue long-term follow-up for patients with chronic radiodermatitis.

    This paper describes the pathological changes observed on the skeleton of a c.12-14 year old person buried in a north-east England Quaker cemetery dated to AD 1711-1857. Bone formation (woven and lamellar) and destruction are present mainly on the mandible, clavicles, sternum and scapulae, long bones of the right arm, left ribs, spine, ilia, and the femora and tibiae. Differential diagnoses of tuberculosis and other pulmonary diseases, smallpox, actinomycosis, neoplastic disease, and "phossy jaw" are considered. While the pathological changes could represent all previously described diseases and thus be associated with the insalubrious conditions in which this person lived, it is also possible that this person worked in the matchmaking industry known to be present in the region at the time. Attention is drawn to the previously overlooked condition "phossy jaw" caused by phosphorus poisoning, which was strongly associated with this industry. While matchstick making was an industry often associated with women and girls, DNA analysis of a bone sample from the skeleton did not successfully identify biological sex. Two dental calculus samples from this person were analysed for phosphorus, and comparisons were made with samples from the same and a different site; the levels did not indicate the person was more exposed to phosphorus than any of the other people at Coach Lane. However, the pathological lesions described also have relevance in a clinical context, because "phossy jaw" has been observed in living populations, arising as a consequence of ingesting phosphorous contained within some pharmaceuticals used for treating neoplastic disease and osteoporosis.

    Anaerobes are the first and Streptococcus species the second most common cause of community-acquired lung abscess (CALA) in the West. The etiologic pathogens of this disease have changed in Taiwan, with Klebsiella pneumoniae being reported as the most common cause of CALA. To determine the etiologies of community-acquired lung abscess. We retrospectively reviewed the records of 205 Japanese adult patients with CALA to evaluate etiologies and outcomes. We used not only traditional microbiological investigations but also percutaneous ultrasonography-guided transthoracic needle aspiration and protected specimen brushes. Of these 205 patients, 122 had documented bacteriological results, with 189 bacterial species isolated. Pure aerobic, mixed aerobic and anaerobic, and pure anaerobic bacteria were isolated in 90 (73.8%), 17 (13.9%), and 15 (12.3%) patients, respectively. The four most common etiologic pathogens were Streptococcus species (59.8%), anaerobes (26.2%), Gemella species (9.8%), and K. pneumoniae (8.2%). Streptococcus mitis was the most common among the Streptococcus species. Mean duration of antibiotic administration was 26 days. Six patients (2.9%, 3 with actinomycosis and 3 with nocardiosis) were treated with antibiotics for 76-189 days. Two patients with anaerobic lung abscess died. The first and second most common etiologic pathogens of CALA in our hospital were Streptococcus species and anaerobes, respectively. The etiologies in our study differ from those in Taiwan and are similar to those in the West with the exception that Streptococcus species were the most common etiologic pathogens in our study whereas anaerobes are the most frequent etiologic pathogens in Western countries. S. mitis and Gemella species are important etiologic pathogens as well. The identification of Actinomyces and Nocardia is important in order to define the adequate duration of antibiotic administration. Copyright 2010 S. Karger AG, Basel.

    Purpose: To assess the accuracy and clinical usefulness of CT-guided core-needle biopsy in the diagnosis of omental pathology. Material and Methods: We retrospectively reviewed the results of CT-guided percutaneous core biopsies in 25 patients with focal (n=2) or diffuse (n=23) omental pathology. These results were compared to the final diagnoses as determined by laparotomy (n=15), laparoscopic biopsy (n=3), endoscopic biopsy (n=1), or by the results of percutaneous biopsy and clinical-radiological and bacteriological modalities (n=6). The final diagnoses showed 4 patients with isolated omental pathology and 21 with widespread peritoneal involvement. The CT-guided biopsies were performed with 1.0=1.8-mm Surecut core-needles. Results: In 16 patients, the final diagnosis was metastatic adenocarcinoma - with the primary tumor sites in the ovary (n=3), stomach (n=1), appendix (n=2), and unknown (n=10). In the remaining 9 patients, the final diagnosis was hepatocellular carcinoma, lymphoma, and mesothelioma in 1 patient each; tuberculosis in 5; and actinomycosis in 1. Sufficient histological (n=16) or cytological (n=8) material was obtained by CT biopsy in 24/25 (96%) cases; the specimen was insufficient for diagnosis in 1 case. In differentiating benign from malignant disease, CT-guided biopsy showed a sensitivity, specificity and accuracy of respectively 89.5%, 100% and 92%. It gave a specific diagnosis in 78.9% (15/19) of patients with malignant conditions and in 50% (3/6) of patients with benign disorders. There were no biopsy-related complications. Conclusion: CT-guided percutaneous core-needle biopsy of the omentum is a safe, useful and highly accurate procedure for diagnosing malignant omental pathology. (orig.)

    The paper provides the annotation and data on sequencing the antibiotic resistance genes in Streptomyces fradiae strain ATCC19609, highly sensitive to different antibiotics. Genome analysis revealed four groups of genes that determined the resistome of the tested strain. These included classical antibiotic resistance genes (nine aminoglycoside phosphotransferase genes, two beta-lactamase genes, and the genes of puromycin N-acetyltransferase, phosphinothricin N-acetyltransferase, and aminoglycoside acetyltransferase); the genes of ATP-dependent ABC transporters, involved in the efflux of antibiotics from the cell (MacB-2, BcrA, two-subunit MDR1); the genes of positive and negative regulation of transcription (whiB and padR families); and the genes of post-translational modification (serine-threonine protein kinases). A comparative characteristic of aminoglycoside phosphotransferase genes in S. fradiae ATCC19609, S. lividans TK24, and S. albus J1074, the causative agent of actinomycosis, is provided. The possibility of using the S. fradiae strain ATCC19609 as the test system for selection of the macrolide antibiotic oligomycin A derivatives with different levels of activity is demonstrated. Analysis of more than 20 semisynthetic oligomycin A derivatives made it possible to divide them into three groups according to the level of activity: inactive (>1 nmol/disk), 10 substances; with medium activity level (0.05–1 nmol/disk), 12 substances; and more active (0.01–0.05 nmol/disk), 2 substances. Important for the activity of semisynthetic derivatives is the change in the position of the 33rd carbon atom in the oligomycin A molecule.

    , Bacteroides capillosus and Anaerobic gram negative bacilli were isolated, sensitive to Metronidazol, Clindamycin, Imipenem and Amoksicilin with Clavulonic Acid. The definite diagnosis was tuboovarian abscess caused by actinomyces complicated with etiologically undeterminated cerebritis. Conclusions: Tuboovarian abscess in a postmenopausal woman as a cause for brain inflammation or abscess is an absolute rarity. Actinomyces species are not generally considered as a part of the normal vaginal flora but rather are associated with the presence of a foreign body, most often an IUD. It is a chronic supurative infection, with a tendency to form abscess. Pelvic actinomycosis is a rare bacterial disease in women (3. It is difficult to diagnose because of the non specific clinical symptoms and imaging findings. Treatment is not standardized and depends on the clinical form. Medical therapy is based on long-term Penicillin G (4. The prognosis of correctly treated pelvic actinomycosis is generally good (3, 4. Experiences with the infection of the CNS by Actinomyces showed that it is potentially fatal (5 and should be considered in those patients with cerebral abscesses or cerebral infection as evident from our case.
