BACKGROUND AND PURPOSE The cause of posterior reversible encephalopathy syndrome (PRES) is unknown. Two primary hypotheses exist: 1) hypertension exceeding auto-regulatory limits leading to forced hyper-perfusion and 2) vasoconstriction and hypo-perfusion leading to ischemia with resultant edema. The purpose of this study was to evaluate the catheter angiography (CA), MR angiography (MRA), and ...

Posterior reversible encephalopathy syndrome (PRES) is characterized by acute reversible subcortical vasogenic edema that is typically bilateral and self-limiting. It preferentially affects posterior regions of the brain. Clinical manifestations include encephalopathy, seizures, headache, and cortical blindness. PRES may be precipitated by hypertensive crises such as eclampsia and by immunosupp...

admitted to hospital for thunderclap headache, blurred vision and hypertension. Based on clinical manifestations, diagnostic work-up and follow-up, the authors diagnosed the case as posterior reversible encephalopathy syndrome (PRES) [1]. We agree that PRES should be considered in this case, while diff erential diagnosis such as subarachnoid hemorrhage (SAH) requires further investigation and e...

RATIONALE Posterior reversible encephalopathy syndrome (PRES), which diagnosis is based on clinical symptoms and radiological features, is a neurotoxic disease characterized by a set of clinical manifestations, such as seizure, headache, visual, and/or consciousness disturbance. It is the first case of PRES followed by postpartum hemorrhage (PPH) without underlying disease. PATIENT CONCERNS A...

In this paper we focus on some aspects related to modeling and formal verification of embedded systems. Many models have been proposed to represent embedded systems [1] [2]. These models encompass a broad range of styles, characteristics, and application domains and include the extensions of finite state machines, data flow graphs, communication processes and Petri nets. In this report, we have...

Recurrent reports about protease-sensitive sites in the junction of the preS and S region of the hepatitis B virus large surface protein have raised the question about a possible biological role of S protein-depleted, independent preS protein fragments in the virus life cycle. In the present study, this question was addressed by exogenous introduction of fluorescence-labeled recombinant preS pr...

BACKGROUND This study aimed to evaluate the clinical features of posterior reversible encephalopathy syndrome (PRES) in children. METHODS The medical records of 31 patients from five medical centers who were diagnosed with PRES from 2001 to 2013 were retrospectively analyzed. In the 31 patients, 16 were males, and 15 females, with a median age of 7 years (3-12 years). Patients younger than 10...

Introduction: Posterior reversible encephalopathy syndrome (PRES) is a neuro-radiological syndrome affecting the posterior cerebral regions and is associated with an accelerated rise in blood pressure, renal disease or autoimmune disorders. Our objective was to review the association of PRES with renal outcome. Materials and Methods: Retrospective review of all nephrology patients diagnosed wit...

We are reporting a case of posterior reversible encephalopathy syndrome (PRES) developed in an unusual clinical scenario without the presence of the most described symptoms. PRES is a neurological and radiological syndrome described in many different clinical conditions. In children it has been mostly reported in association with hematological and renal disorders.Our patient was a 15 years old ...

Posterior Reversible Encephalopathy Syndrome (PRES) is an acute encephalopathy characterized by headache, altered consciousness, visual symptoms and convulsions. Diagnosis supported Magnetic resonance imaging (MRI) of the Brain. Here we report a case PRES in 24-year-old-male who showed complete recovery with control blood pressure. Finally Post Infectious Glomerular Nephritis (PIGN) was found t...
