Vancomycin resistant Enterococcus faecium (VRE) vertebral osteomyelitis after uneventful spinal surgery: A case report and literature review
2017
Abstract Objective Case report and literature review. Background Enterococcus faecium is an emerging pathogen responsible for post procedural infections in patients who have undergone spinal decompression surgery. In this case report, the authors discuss and review recent literature on approaches to post-operative spinal infection. Case report We herein report the case of a 55-year-old HIV-negative Caucasian Italian woman who showed vertebral osteomyelitis with abscesses around the interbody cage caused by an Enterococcus faecium vancomycin resistant gen-Van A, following a Transforaminal Lumbar Interbody Fusion (TLIF). The same strain was detected in disc biopsy, urine culture and rectal sw…
The Unsolved Conundrum of Optimal Blood Pressure Target During Acute Haemorrhagic Stroke: A Comprehensive Analysis
2019
Intracerebral haemorrhage (ICH) is a devastating cerebrovascular disease, which accounts to 15% of all strokes. Among modifiable risk factors for ICH, hypertension is the most frequent. High blood pressure (BP) is detected in more than 75–80% of patients with ICH. Extremely elevated BP has been associated with early hematoma growth, a relatively frequent occur-rence and powerful predictor of poor outcome in patients with spontaneous ICH. On the other hand, excessively low BP might cause cerebral hypoperfusion and ultimately lead to poor outcome. This review will analyse the most important trials that have tried to establish how far should BP be lowered during acute ICH. These trials have de…
Successful management of a cerebral abscess secondary to chronic cholesteatoma caused by Prevotella melaninogenica and Peptococcus anaerobius – A cas…
2016
Abstract Cerebral abscess following cholesteatomatous otomastoiditis is a life-threatening complication and poses diagnostic and therapeutic challenges. We report a case of life-threatening cerebritis and cerebral abscess due to a collection of pus from an aerobic super infections occurring months after the apparent resolution of an otogenic brain abscess in a 67-year-old immunocompetent Italian female. Two gram-positive anaerobic pathogens were isolated during secondary neurosurgical procedures and antibiotic treatment was adopted to resolve the complications. Another objective of this study was to review the literature on gram-positive anaerobic pathogens and brain abscess complications i…
Vessel shape alterations of the vertebrobasilar arteries in Mucopolysaccharidosis type IVa (Morquio A) patients.
2017
Main symptom of mucopolysaccharidosis type IVa (MPS IVa) is progressive systemic skeletal dysplasia. This is routinely monitored by cerebral and spinal MRI. The vascular system is generally not in the primary focus of interest. In our population of MPS IVa patients we observed vessel shape alterations of the vertebrobasilar arteries, which has not been described before.MRI-datasets of 26 patients with MPS IVa acquired between 2008 and 2015 were eligible for retrospective analysis of the vertebrobasilar arteries. The vessel length and angle of the basilar artery (BA) and both vertebral arteries (VA) were analyzed. A deflection angle between 90° and 130° in the vessel course was defined as to…
Can mild cognitive impairment be stabilized by showering brain mitochondria with laser photons?
2019
There is now substantial evidence that cerebral blood flow (CBF) declines with age. From age 20 to 60, CBF is estimated to dip about 16% and continues to drop at a rate of 0.4%/year. This CBF dip will slowly reduce oxygen/glucose delivery to brain thus lowering ATP energy production needed by brain cells to perform normal activities. Reduced ATP production from mitochondrial loss or damage in the wear-and-tear of aging worsens when vascular risk factors (VRF) to Alzheimer's disease develop that can accelerate both age-decline CBF and mitochondrial deficiency to a level where mild cognitive impairment (MCI) develops. To date, no pharmacological or any other treatment has been successful in r…
When Does Alzheimer′s Disease Really Start? The Role of Biomarkers
2021
While Alzheimer’s disease (AD) classical diagnostic criteria rely on clinical data from a stablished symptomatic disease, newer criteria aim to identify the disease in its earlier stages. For that, they incorporated the use of AD’s specific biomarkers to reach a diagnosis, including the identification of Aβ and tau depositions, glucose hypometabolism, and cerebral atrophy. These biomarkers created a new concept of the disease, in which AD’s main pathological processes have already taken place decades before we can clinically diagnose the first symptoms. Therefore, AD is now considered a dynamic disease with a gradual progression, and dementia is its final stage. With …
Nocardiose cérébrale et pulmonaire à Nocardia abscessus chez un patient algérien immunocompétent
2018
International audience; Nocardial brain abscess is often occurring in immunocompromised patients. It is uncommon in immunocompetent individuals. Here, the authors describe a case of cerebral and pulmonary nocardiosis mimicking a metastatic tumor in an apparently health 40-year-old Algerian male. The patient presented multiple brain abscess revealed by inaugural epileptic seizure. He was afebrile and presented with left hemiparesis. Staging imaging showed a nodular lung lesion in the apical segment of the right lower lobe. The patient underwent double craniotomy for resection of the lesion. Culture of the resected specimen isolated Nocardia abscessus. The patient was initially started on int…
Peripheral Blood and Cerebrospinal Fluid Cytokine Levels in Guillain Barré Syndrome: A Systematic Review and Meta-Analysis
2019
Background: Guillain Barre Syndrome (GBS) is an autoimmune disorder caused by the immune-mediated damage of the peripheral nervous system. Increasing evidence suggests that inflammatory cytokines are important mediators for the onset and progression of GBS. A number of clinical studies have demonstrated elevated levels of T helper-1 (Th1-), Th2-, and Th17-related cytokines in patients with GBS; however, the results were inconsistent across studies. Methods: We performed a systematic review and a meta-analysis of studies comparing the levels of inflammatory cytokines in the cerebrospinal fluid and peripheral blood between patients with GBS and healthy individuals, using Comprehensive Meta-An…
New insights about the putative role of myokines in the context of cardiac rehabilitation and secondary cardiovascular prevention.
2017
Exercise training prevents the onset and the development of many chronic diseases, acting as an effective tool both for primary and for secondary prevention. Various mechanisms that may be the effectors of these beneficial effects have been proposed during the past decades: some of these are well recognized, others less. Muscular myokines, released during and after muscular contraction, have been proposed as key mediators of the systemic effects of the exercise. Nevertheless the availability of an impressive amount of evidence regarding the systemic effects of muscle-derived factors, few studies have examined key issues: (I) if skeletal muscle cells themselves are the main source of cytokin…
The VIRSTA score, a prediction score to estimate risk of infective endocarditis and determine priority for echocardiography in patients with Staphylo…
2016
International audience; Objectives - To develop and validate a prediction score, to quantify, within 48 h of Staphylococcus aureus bacteremia (SAB) diagnosis, the risk of IE, and therefore determine priority for urgent echocardiography. Methods - Consecutive adult patients with SAB in 8 French university hospitals between 2009 and 2011 were prospectively enrolled and followed-up 3 months. A predictive model was developed and internally validated using bootstrap procedures. Results - Among the 2008 patients enrolled, 221 (11.0%) had definite IE of whom 39 (17.6%) underwent valve surgery, 25% of them within 6 days of SAB diagnosis. Ten predictors independently associated with IE were used to …
