INTRODUCTION Acute apical abscess is caused by bacteria that leave the infected dental root canal to invade the periodontal tissues. Most species occurring in abscesses are also found in asymptomatic infections; therefore, the possibility exists that not only the presence of certain species but also their specific counts influence the appearance of symptoms. This molecular study compared the fr...

In this report, we describe the appearance of the spinal vertebral body and epidural abscesses in a patient who underwent diffusion-weighted imaging of the spine and CT-guided aspiration of one of the abscesses. The abscesses were hyperintense relative to the surrounding tissues on diffusion-weighted images, and they appeared dark on apparent diffusion coefficient maps; these findings were cons...

Bacteroides fragilis produces a capsular polysaccharide complex (CPC) that is directly involved in its ability to induce abscesses. Two distinct capsular polysaccharides, polysaccharide A (PS A) and PS B, have been shown to be synthesized by the prototype strain for the study of abscesses, NCTC9343. Both of these polysaccharides in purified form induce abscesses in animal models. In this study,...

The encouraging results of percutaneous abscess drainage (PAD) in simple intra-abdominal abscesses have led us to employ this method in patients with more complex abdominal inflammatory disease, such as those with multiple enteric communicating or multilocular abscesses and patients in whom the percutaneous approach requires puncture routes traversing uninvolved organs. Cure was achieved in 74 ...

AIMS Pancreatic abscesses are treated surgically and the role of endotherapy is still to be established. We describe the case of successful endoscopic management of two pancreatic abscesses in a critically ill patient. METHODS A patient was admitted to the hospital for severe acute pancreatitis. One month later the patient developed pancreatic sepsis. CT scan showed two large abscesses. The f...

Streptococcus intermedius is a member of the Streptococcus anginosus group of bacteria. This group is part of the normal flora of the oropharynx, genitourinary, and gastrointestinal tracts; however, they have been known to cause a variety of purulent infections including meningitis, endocarditis, and abscesses, even in immunocompetent hosts. In particular, S. intermedius has been associated wit...

Liver abscesses in slaughtered beef cattle result from aggressive grain-feeding programs. The incidence, averaging from 12 to 32% in most feedlots, is influenced by a number of dietary and management factors. Liver abscesses represent a major economic liability to producers, packers, and ultimately consumers. Besides liver condemnation, economic impacts include reduced feed intake, reduced weig...

Nasal septum abscesses caused by uncontrolled diabetes mellitus are rare. We report 3 cases. Very few cases have been published concerning non-traumatic nasal septum abscesses. The development of the condition, possible complications, and treatment are discussed.

  Chronic granulomatous disease (CGD) is a rare inherited disorder characterized by inability of phagocytes to generate oxygen radicals needed for intracellular killing of phagocytic microorganisms. We report a 2.5-year-old Iranian female with multiple liver abscesses. She was admitted in surgical ward because of abdominal pain and fever for one month duration that had no response to conventio...

BACKGROUND AND PURPOSE Abscesses caused by aerobic bacteria (aerobic abscesses) can simulate intracranial glioblastomas multiforme (GBMs) in MR imaging appearance and single voxel (SV) proton MR spectroscopy of the central cavity. The purpose of our study was to determine whether MR spectroscopic imaging (SI) can be used to differentiate aerobic abscesses from GBMs. Our hypothesis was that meta...
