Liver abscess is a rare but potentially fatal disease with mortality rates of 2 - 12 %. The spectrum of causative microorganisms varies across the world and is changing due to increasing worldwide travel activity. As a result, previously less frequent pathogens must increasingly be considered in the differential diagnosis. The most common pathogens of liver abscess are so-called abscess streptococci, anaerobes and Gram-negative bacteria such as Escherichia coli and Klebsiella pneumoniae. Certain clones among the Gram-negatives, typically among Klebsiella spp...

A 56-year-old woman, without any immunocompromising diseases, was referred to our hospital because of a recurrence of pyogenic spondylitis. Computed tomography revealed multiple osteolytic changes in the whole body. Vertebral magnetic resonance imaging revealed osteomyelitis and spondylitis. Mycobacterium scrofulaceum was detected in sputum cultures, in abscesses from the right knee, and in a subcutaneous forehead abscess. Therefore, the patient was diagnosed with disseminated Mycobacterium scrofulaceum infection...

Tuberculous mastititis is a rare clinical entity and usually affects women from the Indian subcontinent. It often mimics breast carcinoma and pyogenic breast abscess. Fine needle aspiration cytology (FNAC) is a very essential diagnostic tool when other routine laboratory investigations are not helpful in reaching to the conclusion. Tuberculosis (TB) of the breast is an uncommon presentation of TB even in countries where the incidence of pulmonary and extrapulmonary TB is high. Radiological imaging is not diagnostic...

BACKGROUND: Despite equivocal evidence, non-surgical management for pyogenic liver abscess (PLA) has become the standard of care at most institutions with surgery relegated to salvage therapy for those who fail less invasive means. The aim of this study was to describe the outcomes of a step-up approach to PLA management. METHODS: A retrospective chart review was conducted at a single institution for patients diagnosed with PLA over a 10-year period. Demographic, radiologic, microbiological, treatment, and outcomes data were collected and analyzed...

Septic arthritis of the temporomandibular joint (SATMJ) is a rare entity that has only been reported a few dozen times worldwide. However, SATMJ is an acute infectious disease and associated with a high risk for misdiagnosis, which results in severe complications for patients. The present study reported a case of an 83-year-old female patient with severe pyogenic orofacial infections caused by right-side SATMJ, which was not cured by abscess incision drainage and anti-microbial treatment. Finally, the clinical signs were resolved by condylectomy and debridement of the erosive septic TMJ, after which the function of the TMJ was completely restored...

Obturator internus muscle (OIM) abscess is an uncommon condition often mistaken for bacterial infection of the hip joint. If the OIM abscess is accompanied by a septic hip, it becomes more difficult to make a diagnosis. Surgical drainage of OIM abscess is difficult because it is located at a deep part of the pelvic cavity. Therefore, intravenous antibiotic therapy or image-guided aspiration were used as a treatment method instead of surgical drainage. When drainage of the abscess was inadequate, prolonged antibiotic treatment was necessary...

BACKGROUND: Pyogenic liver abscesses (PLA) remain a significant clinical problem. Unfortunately, little is known about current bacterial susceptibility profiles and the incidence of multidrug resistant organisms (MDROs) causing PLA in Western countries. Yet, this crucial information is pivotal to guide empirical antibiotic therapy. Aim of this study was to provide detailed characteristics of PLA with a special focus on underlying bacterial pathogens and their susceptibility to antibiotics...

Trueperella pyogenes is an opportunistic pathogen that causes diverse pyogenic infections in livestock. The genes that encode the exotoxin pyolysin (plo) and other putative factors that promote adhesion of pathogen to host cells (fimbriae fimA, fimC, fimE, fimG, neuraminidases nanH, nanP, and collagen-binding protein cbpA) have been associated with virulence, particularly in mastitis and uterus infections of dairy cows. However, the role of these virulence markers in the pathogenicity of the agent in domestic animals infections still is incompletely understood...

A 15-year old boy was referred for evaluation of fever, productive cough, and recurrent/persistent right lower lobe (RLL) pneumonia of 1-month duration. Chest computed tomography scan showed RLL consolidation, with minimal pleural effusion and a liver abscess with sharp borders, containing a solid calcification in the lower portion. History revealed acute appendicitis with laparoscopic appendectomy 6 months prior to presentation, during which a fecalith dropped to the peritoneal cavity. Following laparoscopically guided drainage of the abscess the patient improved...

Brain abscesses due to Enterobacteriaceae in immune-competent children are rare, and those due to Enterobacter cloacae are even rarer. We report an interesting case of community-acquired E. cloacae neuroinfection resulting in multiple brain abscesses in a young child with no underlying risk-factors. A 10 year-old-boy presented with low-grade fever, headache, neck pain and progressive deterioration of sensorium. On examination, he was conscious but drowsy with photophobia, normal fundii, meningeal signs, mild hypertonia, brisk muscle stretch reflexes and extensor plantar responses...

An isolated pyogenic pancreatic abscess (IPPA) without pancreatitis is extremely rare but can occur in patients with uncontrolled diabetes. This pathologic condition poses a clinical challenge in diagnosis and management because it can be confused easily with a malignancy. Endoscopic ultrasound (EUS) may be a useful diagnostic modality for indeterminate pancreatic lesions and IPPA. Here, we report two cases with elevated carbohydrate antigen 19-9 levels and pancreatic masses on cross sectional imaging. The patients were subsequently diagnosed with IPPA by EUS...
