brain abscess guidelines

Infective endocarditis (IE) is today a public health problem, as the recent ESC Guidelines have also recalled. Abscesses can be complications of IE and their presence means that the infection is not controlled. We describe the complex case of a 57-year-old patient, presented in ED for fever and oleocranical bursitis, increase of cardiac enymes at blood samples. He was admitted to our Cardiology Unit because TTE showed a floating peduncolated formation in the left ventricle. The susequent TEE documented also the presence of a myocardial abscess, confirmed at cardiac MRI...

We present a case of Listeria monocytogenes  brain abscess in an immunocompromised patient admitted for stroke-like symptoms of headache and aphasia. Computerized tomography of the head revealed a 1.7 x 1.3 cm left frontal lobe lesion with surrounding edema, secondary to stroke, tumor, or abscess. Magnetic resonance imaging brain revealed a ring-enhancing lesion and a small contralateral area of restricted diffusion. Two of the two blood cultures grew an organism identified as L. monocytogenes using matrix-assisted laser desorption ionization time-of-flight mass spectrometry...

BACKGROUND: With artificial intelligence (AI) on the rise, it remains unclear if AI is able to professionally evaluate medical research and give scientifically valid recommendations. AIM: This study aimed to assess the accuracy of ChatGPT's responses to ten key questions on brain abscess diagnostics and treatment in comparison to the guideline recently published by the European Society for Clinical Microbiology and Infectious Diseases (ESCMID). METHODS: All ten PECO (Population, Exposure, Comparator, Outcome) questions which had been developed during the guideline process were presented directly to ChatGPT...

BACKGROUND: Actinomyces turicensis is rarely responsible of clinically relevant infections in human. Infection is often misdiagnosed as malignancy, tuberculosis, or nocardiosis, therefore delaying the correct identification and treatment. Here we report a case of a 55-year-old immunocompetent adult with brain abscess caused by A. turicensis. A systematic review of A. turicensis infections was performed. METHODS: A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

SCOPE: These European Society of Clinical Microbiology and Infectious Diseases guidelines are intended for clinicians involved in diagnosis and treatment of brain abscess in children and adults. METHODS: Key questions were developed, and a systematic review was carried out of all studies published since 1 January 1996, using the search terms 'brain abscess' OR 'cerebral abscess' as Mesh terms or text in electronic databases of PubMed, Embase, and the Cochrane registry...

Acrophialophora is a saprotrophic genus of fungi found in both temperate and tropical regions. The genus is comprised of 16 species, with the subspecies A. fusispora and A. levis  necessitating the most clinical concern. Acrophialophora is an opportunistic pathogen with a broad range of clinical manifestations; the fungus   has been implicated in cases of fungal keratitis, lung infection, and brain abscess. Acrophialophora infection is particularly of concern for immunocompromised patients, who often present with a more severe disease course involving disseminated infection and may not exhibit typical symptoms...

BACKGROUND: Early switch to oral antimicrobials has been suggested as a treatment strategy in patients with brain abscess, but the practice is controversial. OBJECTIVES: This review aimed to summarize the background, current evidence, and future perspectives for early transition to oral antimicrobials in patients with brain abscess. SOURCES: The review was based upon a previous systematic review carried out during the development of the ESCMID guidelines on diagnosis and treatment of brain abscess...

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, is a rare disorder with a case prevalence as high as one in 5000, causing arteriovenous malformations in multiple organ systems. HHT is familial with autosomal dominant inheritance, with genetic testing allowing confirmation of the diagnosis in asymptomatic kindreds. Common clinical manifestations are epistaxis and intestinal lesions causing anemia and requiring transfusions. Pulmonary vascular malformations predispose to ischemic stroke and brain abscess and may cause dyspnea and cardiac failure...

Nocardia species are aerobic, gram-positive, filamentous bacteria. Infection occurs either through inhalation leading to pulmonary symptoms or inoculation presenting with skin findings. Hematogenous dissemination, although uncommon, is possible and can lead to central nervous system involvement. Nocardia  brain abscess is a rare manifestation that comprises 2% of all brain abscess etiologies, mostly occurring in immunocompromised patients. Establishing a diagnosis is often difficult, especially due to its rare occurrence and the fact that it can mimic other etiologies on brain imaging including necrotic tumors...

Recipients of solid organ transplants are at risk for a variety of infections due to their immunocompromised status. The types of infections are often correlated to the timing from their transplant. After about six to twelve months, transplant recipients remain at risk for typical community acquired pathogens, late viral infections, and fungal infections including atypical molds such as Cladophialophora bantiana. C. bantiana is a dematiaceous fungus that has a predilection for infecting the brain and is the most common cause of cerebral phaeohyphomycosis - a term used to describe infections caused by molds that produce dark cell walls...

Background: Citrobacter species are an unusual cause of cerebral abscess in infant. In particular, Citrobacter freundii can invade and replicate in human brain microvascular endothelial cells with a selective neurovirulence, producing ventriculitis and brain abscess mainly in the infant. A delayed brain abscess caused by C. freundii species in adult patients and after surgery is an occurrence that has not yet been reported in the literature. Case Description: The authors reported a case of a 60-year-old patient that presented a delayed postoperative brain abscess following resection of a left parietal convexity meningioma...

OBJECTIVE: Decompressive craniectomy (DC) is the definitive neurosurgical treatment for managing refractory malignant cerebral edema and intracranial hypertension due to combat-related severe traumatic brain injury (TBI). To date, the long-term outcomes and sequelae of this procedure on host-country national (HCN) populations during Operation Iraqi Freedom (Iraq, 2003-2011), Operation Enduring Freedom (Afghanistan, 2001-2014), and Operation Freedom's Sentinel (Afghanistan, 2015-2021) have not been described, specifically the process and results of delayed custom synthetic cranioplasty...

Fluorescence-guided surgery with 5-aminolevulinic acid (5-ALA) is used to assist brain tumor resection, especially for high-grade gliomas but also for low-grade gliomas, metastasis, and meningiomas. With the increasing use of this technique, even to assist biopsies, high-grade glioma-mimicking lesions had misled diagnosis by showing 5-ALA fluorescence in non-neoplastic lesions such as radiation necrosis and inflammatory or infectious disease. Since only isolated reports have been published, we systematically review papers reporting non-neoplastic lesion cases with 5-ALA according with the PRISMA guidelines, present our series, and discuss its pathophysiology...

DESIGN: The review was performed according to the PRISMA guidelines and registered on PROSPERO. The search was carried out in PubMed electronic database for articles published until March 2020. Eligibility criteria were: case reports, case series, and retrospective studies...

Cerebral nocardia infections is a rare entity, which has been mainly reported in immunosuppressed patients. Currently, there are no clinical guidelines for first-line treatment. Our case refers to an older immunocompetent adult, with encephalopathy and left hemiparesis, associated with lesions compatible with multiple brain abscess and suggestive of infectious etiology. He initially received treatment for tuberculosis, bacterial abscess, and toxoplasmosis, without a favorable clinical response. An empirical treatment for nocardiosis started, by using meropenem and trimethoprim / sulfamethoxazole, and clinical and imaging improvement was achieved...

Hemorrhagic hereditary telangiectasia (HHT) is a rare autosomal dominant disorder that causes multisystem vascular malformations including mucocutaneous telangiectasias and arteriovenous malformations (AVMs). Clinical and genetic screening of patients with signs, symptoms, or a family history suggestive of HHT is recommended to confirm the diagnosis on the basis of the Curaçao criteria and prevent associated complications. Patients with HHT frequently have epistaxis and gastrointestinal bleeding from telangiectasias...

RATIONALE: Nocardiosis is an uncommon and potentially life-threatening infection that usually affects immunocompromised hosts. No clinical guidelines have been established for managing this rare disease, and the optimal treatment modality remains unclear. Nocardia farcinica, a relatively infrequent pathogen of nocardiosis, causes a clinically aggressive infection. In addition to our patient data, our search of the literature for patients who presented with empyema caused by N. farcinica will provide fundamental information for optimal treatment modalities...
