Liver abscesses containing hypervirulent Klebsiella pneumoniae have emerged during the past 2 decades, originally in Southeast Asia and then worldwide. We hypothesized that hypervirulent K. pneumoniae might also be emerging in France. In a retrospective, monocentric, cohort study, we analyzed characteristics and outcomes for 199 consecutive patients in Paris, France, with liver abscesses during 2010-2015. We focused on 31 patients with abscesses containing K. pneumoniae. This bacterium was present in most (14/27, 52%) cryptogenic liver abscesses...

Background Transtemporal Doppler (TTD) with middle cerebral artery (MCA) is widely used for right-to-left shunt (RLS) detection. However, an alternative method for patients without suitable temporal bone windows should be established. The present study prospectively evaluated the effectiveness of transorbital Doppler (TOD) with carotid siphon (CS) monitoring in detecting RLS. Methods A total of 357 subjects with sufficient temporal bone windows underwent simultaneous TTD with MCA and TOD with CS. After injection of microbubbles, the numbers of artificial high-intensity signals were recorded at rest and after Valsalva maneuver...

We had encountered the case of membranous glomerulonephritis (MGN) with dilated cardiomyopathy due to LMNA gene mutation. LMNA mutation was known as a cause of 'laminopathy' such as dilated cardiomyopathy, muscular dystrophy, neuropathy and so on. LMNA gene might be a candidate of genetic basis in cryptogenic MGN.

BACKGROUND AND PURPOSE: Previous systematic reviews and meta-analyses compared the efficacy and safety of patent foramen ovale (PFO) closure versus medical treatment in patients with cryptogenic stroke or transient ischemic attack (TIA). Recently, new evidence from randomized trials became available. METHODS: We searched PubMed until September 24, 2017, for trials comparing PFO closure with medical treatment in patients with cryptogenic stroke/TIA using the items: stroke or cerebrovascular accident or TIA and patent foramen ovale or paradoxical embolism and trial or study...

BACKGROUND: In the general population the leading cause of cardioembolic stroke is atrial fibrillation (AF). A silent AF is also the possible cause of many cryptogenic strokes. P wave dispersion (PWD), a predictor of AF, has been proposed as a marker of silent AF occurrence in these strokes. PWD correlates with high-sensitive C-reactive protein levels reflecting the role of inflammation in promoting a slowed and inhomogeneous atrial conduction. Statins have a multitude of additional effects beyond lipid lowering, in particular anti-inflammatory effects that may influence atrial conduction...

OBJECTIVES: To evaluate the safety and efficacy of percutaneous device closure of patent foramen ovale (PFO) for secondary prevention of ischemic stroke BACKGROUND: Stroke remains the leading cause of serious long-term disability in the United States. The effectiveness of a percutaneous PFO closure in the prevention of recurrent cryptogenic strokes has not been established. METHODS: We performed a literature search using PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Google Scholar, and Internet-based sources from January 2003 to September 2017...

Carotid artery web is considered an exceptional cause of recurrent ischemic strokes in the affected arterial territory. The underlying pathology proposed for this entity is an atypical fibromuscular dysplasia. We present the case of a 43-year-old woman with no cardiovascular risk factors who had experienced 2 cryptogenic ischemic strokes in the same arterial territory within an 11-month period. Although all diagnostic tests initially yielded normal results, detailed analysis of the computed tomography angiography images revealed a carotid web; catheter angiography subsequently confirmed the diagnosis...

INTRODUCTION: There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. METHODS: A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review...

Coastal human-made structures, such as marinas and harbors, are expanding worldwide. Species assemblages described from these artificial habitats are novel relative to natural reefs, particularly in terms of the abundance of nonindigenous species (NIS). Although these fouling assemblages are clearly distinctive, the ecosystem functioning and species interactions taking place there are little understood. For instance, large predators may influence the fouling community development either directly (feeding on sessile fauna) or indirectly (feeding on small predators associated with these assemblages)...

Constrictive pericarditis (CP) is defined as impedance to diastolic filling caused by a fibrotic pericardium. The diagnosis of CP is a clinical challenge and requires a high index of clinical suspicion. The signs and symptoms of CP include fatigue, edema, ascites, and liver dysfunction. These can be mistakenly diagnosed as primary liver disease. We present the case of a 69-year-old woman with a 7-year history of leg edema and a 2-year history of ascites who was initially diagnosed with cryptogenic liver cirrhosis and was finally diagnosed with CP...

The glomerular diseases after renal transplantation can occur de novo, i.e., with no relation to the native kidney disease, or more frequently occur as a recurrence of the original disease in the native kidney. There may not be any difference in clinical features and histological pattern between de novo glomerular disease and recurrence of original glomerular disease. However, structural alterations in transplanted kidney add to dilemma in diagnosis. These changes in architecture of histopathology can happen due to: (1) exposure to the immunosuppression specifically the calcineurin inhibitors (CNI); (2) in vascular and tubulointerstitial alterations as a result of antibody mediated or cell-mediated immunological onslaught; (3) post-transplant viral infections; (4) ischemia-reperfusion injury; and (5) hyperfiltration injury...

OBJECTIVE: Genetic background of cryptogenic ischemic stroke (IS) and transient ischemic attack (TIA) remains uncertain. Alpha-2-antiplasmin (α2AP) Arg407Lys polymorphism has been shown to be less common in patients with abdominal aortic aneurysm (AAA) compared with healthy controls. We investigated associations of α2AP Arg407Lys polymorphism with cryptogenic IS and TIA. METHODS: We studied 165 consecutive Caucasian patients who experienced cryptogenic IS (n=123) or TIA (n=42)...

New evidence suggests that closure of a patent foramen ovale (PFO) plus medical therapy (MT; antiplatelet or anticoagulation) is superior to MT alone to prevent recurrent cryptogenic stroke. We performed a meta-analysis of randomized controlled trials that compared PFO closure plus MT with MT alone in patients with cryptogenic stroke. The efficacy end points were recurrent stroke, transient ischemia attack, and death. The safety end points were major bleeding and newly detected atrial fibrillation. Trials were pooled using random effects and fixed effects models...

Autoimmune and unknown/cryptogenic encephalitis have been increasingly noted in the inflammatory etiology of new-onset status epilepticus (SE). We aimed to investigate clinical characteristics and the potential role of immunotherapy in encephalitis-related adult SE through our multicenter prospective SE registry. Among the 274 patients with SE, 35 (12.8%) patients demonstrated an inflammatory etiology and 19 out of 35 (54.3%) patients demonstrated unknown/cryptogenic cause. Patients with autoimmune and unknown/cryptogenic encephalitis shared similar clinical features...

Contrasting with three randomized trials that failed to show any superiority of patent foramen ovale closure over antithrombotic therapy, two trials recently reported lower rates of stroke recurrence among patients assigned to patent foramen ovale closure than among those assigned to antiplatelet therapy. In addition, one of the initially negative trials concluded in favor of patent foramen ovale closure after an extended follow-up period. A better selection of patients, the use of reference treatment groups that included patients who received antiplatelet therapy alone (rather than antiplatelet drugs or oral anticoagulants, according to physician preference), and a longer follow-up of patients, may explain the divergent findings across studies...

Diagnosis, treatment, and secondary management of cryptogenic stroke patients pose a formidable challenge. The scenario is further complicated in patients with native and prosthetic valvular heart disease. We present a case study of a 36-year-old man who received intravenous thrombolysis (IV-tPA) and endovascular thrombectomy (EVT) for presumed "cryptogenic" complete middle cerebral artery infarction who made a surprisingly excellent clinical recovery despite poor baseline and postintervention neuroimaging...
