Project description:AudienceEmergency medicine residents of all levels.IntroductionPosterior reversible encephalopathy syndrome (PRES) is a clinically significant cause of seizures, headache, neurologic deficit, and hypertensive emergency that is not uncommon in the emergency department. Posterior reversible encephalopathy syndrome was initially described as a clinical syndrome in 1996.1 It is an important cause of hypertensive emergency that is not often covered in depth in the emergency medicine curriculum since the true incidence and disease process continues to be researched.Populations who are at most risk for PRES include those with chronic hypertension, chronic renal disease, autoimmune disease, and immune suppression.2 Patients with PRES will often present with varied forms of encephalopathy and sometimes even focal neurologic symptoms that would suggest a cerebral vascular accident. These neurologic symptoms can include visual complaints and headache. Seizures are also frequently reported in association with PRES.3Early identification and appropriate management of PRES decreases morbidity and mortality without chronic neurologic sequelae. The pillars of diagnosis and management can be initiated in the emergency department. This includes a diagnosis made by a thorough history and physical exam and cerebral imaging.4 The mainstay of management is parenteral anti-hypertensives with proper blood pressure monitoring.5.Educational objectivesBy the end of the simulation, the learner will be able to: 1) manage an acute seizure 2) discuss imaging modalities to diagnose PRES 3) discuss medical management of PRES.Educational methodsThis simulation exercise is meant to be presented as a traditional medium-to-high-fidelity medical simulation case. With minor adjustments, it could be utilized as a low-fidelity case or an oral exam case.Research methodsThe educational content and general usefulness of this simulation was evaluated by open verbal (qualitative) feedback from a convenience sample of random participants following a completion of the case and debriefing by a participant group (n=30) of emergency medicine residents at a large 3-year residency training program.ResultsThe overall feedback was positive. Participants felt that it was a good opportunity to practice identifying PRES and managing it in a safe learning environment. They especially appreciated learning more about the pathophysiology of PRES, the high-risk factors for PRES, and management of the condition.DiscussionPosterior reversible encephalopathy syndrome, an uncommon condition, presents similar to many other benign and common complaints. It is crucial to be able to differentiate PRES from other causes of headache, visual disturbance, and seizures. It is important to keep PRES in mind when considering hypertensive emergencies. Many PGY-1 residents struggled to diagnose and treat PRES because it was often not on their differential, and this case helped broaden their differential. PGY-2 and PGY-3 were more frequently able to appropriately diagnose and treat PRES in this patient but found the case to be helpful in their decision-making and learning more about PRES pathophysiology. This case and associated high-yield debriefing session were effective for learners of all levels.TopicsPosterior reversible encephalopathy syndrome (PRES), altered mental status, seizure, headache, hypertensive emergency.

Project description:Diagnosis of Posterior Reversible Encephalopathy Syndrome (PRES) in some circumstances can be challenging and structural imaging may not be sufficient to distinguish it from other differential diagnostic considerations. Advanced imaging techniques, such as MR spectroscopy or positron emission tomography (PET) can provide additional information to determine the diagnosis. Other techniques, such as susceptibility weighted imaging (SWI) improves detection of hemorrhage which has prognostic role. CT or MR Perfusion as well as Single-Photon Emission Computed Tomography (SPECT) are more useful to understand the underlying vasculopathic changes in PRES and may answer some of the unresolved controversies in pathophysiology of this complex disease. In this review we summarized the findings of previous studies using these advanced methods and their utilities in diagnosis or prognosis of PRES.

Project description:The posterior reversible encephalopathy syndrome (PRES) is a neurological disorder of (sub)acute onset characterized by varied neurological symptoms, which may include headache, impaired visual acuity or visual field deficits, disorders of consciousness, confusion, seizures, and focal neurological deficits. In a majority of patients the clinical presentation includes elevated arterial blood pressure up to hypertensive emergencies. Neuroimaging, in particular magnetic resonance imaging, frequently shows a distinctive parieto-occipital pattern with a symmetric distribution of changes reflecting vasogenic edema. PRES frequently develops in the context of cytotoxic medication, (pre)eclampsia, sepsis, renal disease or autoimmune disorders. The treatment is symptomatic and is determined by the underlying condition. The overall prognosis is favorable, since clinical symptoms as well as imaging lesions are reversible in most patients. However, neurological sequelae including long-term epilepsy may persist in individual cases.

Project description:BackgroundCardiac arrest is the most dramatic event that compromises the cerebral blood flow with fatal outcomes. Factors like the presence of bystander cardiopulmonary resuscitation, initial rhythm, and arrest time significantly influence outcomes. However, despite these known factors, there are still aspects of cardiac arrest-related neurological complications that remain less understood. As evidenced by limited case reports, the association between posterior reversible encephalopathy syndrome (PRES) and cardiac arrest is not widely known.Case descriptionWe present a case study of out-of-hospital cardiac arrest (OHCA) involving a patient with multiple comorbidities and factors that could complicate her neurological outcome. Despite experiencing a delayed recovery following the cardiac arrest event and an initial insult to the brain, the patient exhibited remarkable neurological recovery. There has been a complex individualized targeted management that contributed to the favorable outcome.ConclusionsThis case study provides valuable insights into the complexities of managing OHCA patients, the factors influencing recovery, and the importance of a multidisciplinary team for early diagnosis and treatment of conditions like PRES to prevent permanent neurological damage. Further research into this area is necessary to better understand the mechanisms and implications of such associations for improving patient care and outcomes following cardiac arrest.

Project description:IntroductionPosterior reversible encephalopathy syndrome (PRES) and the related term reversible posterior leukoencephalopathy syndrome (RPLS) denote a constellation of clinical symptoms paired with key radiological findings. Eclampsia associated with PRES is a rare condition and remains a challenging diagnosis to make. There are only a few studies regarding PRES syndrome with a limited sample size. Our institution is a tertiary referral centre; hence, a good sample size of patients with eclampsia complicated with PRES syndrome is seen in our study. The objective was to identify the maternal and neonatal outcomes in PRES with eclampsia.MethodsThis study is a prospective observational study done in Government Medical College, Aurangabad, India from October 2018 to September 2020. In the present study, we have enrolled 63 cases, who satisfied inclusion and exclusion criteria during two years. All women admitted in the labour room of tertiary health care centre diagnosed with eclampsia with neurological symptoms during the study period were studied. Relevant data were obtained from the case file and compiled by common proforma. Analysis was done by SPSS (Statistical package for social sciences) Version 25th.ResultsIn patients with a confirmed diagnosis of PRES with eclampsia(n = 63), the mean age of the patient was 20.74 ± 2.04 years, 23 (36.5%) patients had headache as premonitory symptoms, whereas 13(20.6%)patients had visual disturbances as the premonitory symptom. The mean gestational age at presentation was 34.4 ± 2 weeks. 40(63.5%) patients were showing parieto-occipital region changes, and 24(38.1%) subjects were showing only occipital region involvement in CT brain. 12 (19.04%) subjects were diagnosed with HELLP syndrome as a maternal complication, 07 (11.1%) subjects had Abruptio placentae. 26(41.3%) babies needed NICU admission, and 4 (6.3%) babies had neonatal death.ConclusionIn pregnant patients presenting with seizure and neurological symptoms, a possibility of PRES should be considered. Proper diagnosis requires careful attention to clinical and radiographic presentation. In eclampsia with PRES patients, a timely intervention with anti-hypertensive, anti-cerebral oedema measures as well as management of other associated symptoms are required.Supplementary informationThe online version contains supplementary material available at 10.1007/s13224-021-01585-9.

Project description:Background: Posterior reversible encephalopathy syndrome (PRES) is an acute neurotoxic syndrome that is characterized by a spectrum neurological and radiological feature from various risk factors. Common neurological symptoms includes headache, impairment in level of consciousness, seizures, visual disturbances, and focal neurological deficits. Common triggering factors include blood pressure fluctuations, renal failure, eclampsia, exposure to immunosuppressive or cytotoxic agents and autoimmune disorders. The classic radiographic findings include bilateral subcortical vasogenic edema predominantly affecting the parieto-occipital regions but atypical features include involvement of other regions, cortical involvement, restricted diffusion, hemorrhage, contrast enhancement. This review is aimed to summarize the updated knowledge on the typical and atypical clinical and imaging features, prognostic markers and identify gaps in literature for future research. Methods: Systematic literature review using PUBMED search from 1990 to 2019 was performed using terms PRES was performed. Results: While clinical and radiographic reversibility is common, long-standing morbidity and mortality can occur in severe forms. In patients with malignant forms of PRES, aggressive care has markedly reduced mortality and improved functional outcomes. Although seizures were common, epilepsy is rare. Various factors that have been associated with poor outcome include altered sensorium, hypertensive etiology, hyperglycemia, longer time to control the causative factor, elevated C reactive protein, coagulopathy, extensive cerebral edema, and hemorrhage on imaging. Conclusion: Large prospective studies that accurately predict factors that are associated with poor outcomes, determine the pathophysiology, and targeted therapy are required.

Project description:BackgroundPosterior reversible encephalopathy syndrome (PRES) can cause short-term cerebrovascular complications, such as brain infarction and hemorrhage. We hypothesized that PRES is also associated with an increased long-term risk of stroke.MethodsWe performed a retrospective cohort study in the United States using statewide all-payer claims data from 2016 to 2018 on all admissions to nonfederal hospitals in 11 states. Adults with PRES were compared with adults with renal colic (negative control) and transient ischemic attack (TIA; positive control). Any stroke and the secondary outcomes of ischemic and hemorrhagic stroke were ascertained using International Classification of Diseases, Tenth Revision, Clinical Modification codes. We excluded prevalent stroke. We used time-to-event statistics to calculate incidence rates and Cox proportional hazards analyses to evaluate the association between PRES and stroke, adjusting for demographics and stroke risk factors. In a sensitivity analysis, outcomes within 2 weeks of index admission were excluded.ResultsWe identified 1606 patients with PRES, 1192 with renal colic, and 38 216 with TIA. Patients with PRES had a mean age of 56±17 years; 72% were women. Over a median follow-up of 0.9 years, the stroke incidence per 100 person-years was 6.1 (95% CI, 5.0-7.4) after PRES, 1.0 (95% CI, 0.62-1.8) after renal colic, and 9.7 (95% CI, 9.4-10.0) after TIA. After statistical adjustment for patient characteristics and risk factors, patients with PRES had an elevated risk of stroke compared with renal colic (hazard ratio [HR], 2.3 [95% CI, 1.7-3.0]), but lower risk than patients with TIA (HR, 0.67 [95% CI, 0.54-0.82]). In secondary analyses, compared with TIA, PRES was associated with hemorrhagic stroke (HR, 2.0 [95% CI, 1.4-2.9]). PRES was associated with ischemic stroke when compared with renal colic (HR, 1.9 [95% CI, 1.4-2.7]) but not when compared with TIA (HR, 0.49 [95% CI, 0.38-0.63]). Results were similar with 2-week washout.ConclusionsPatients with PRES had an elevated risk of incident stroke.

Project description:Posterior reversible encephalopathy syndrome (PRES) is a reversible neuroradiological syndrome characterized by reversible vasogenic edema. The pathophysiological mechanism is still unclear, but PRES may be triggered by various etiologies. To date, only a few PRES cases linked to cerebrospinal fluid (CSF) hypovolemia were reported. The association between PRES and CSF hypovolemia needs to be explored. We presented a case of PRES with CSF hypovolemia as a result of an inadvertent dural puncture and reviewed the literature to identify the clinical characterization and pathophysiological mechanism of PRES following CSF hypovolemia. A total of 31 cases of PRES-CSF hypovolemia was included for analysis. The median age was 33 years, with a notable female predominance (87.1%). Fifteen patients (48.4%) didn't have either a history of hypertension nor an episode of hypertension. The most common cause of CSF hypovolemia was epidural or lumbar puncture (n = 21), followed by CSF shunt (n = 6). The median interval between the procedure leading to CSF hypovolemia and PRES was 4 days. Seizure, altered mental state, and headache were the most frequent presenting symptom. The parietooccipital pattern was most frequent (71.0%). Conservative management remains the mainstay of treatment with excellent outcomes. Three patients had a second episode of PRES. CSF hypovolemia is a plausible cause of PRES via a unique pathophysiologic mechanism including arterial hyperperfusion and venous dysfunction. Patients with CSF hypovolemia is more susceptible to PRES, which is potentially life-threatening. Given that CSF hypovolemia is a common complication of anesthetic, neurological, and neurosurgical procedures, PRES should be early considered for prompt diagnosis and appropriate management.

Project description:Background and purposePosterior reversible encephalopathy syndrome (PRES) is known to occur after solid organ transplantation (SOT), potentially associated with cyclosporine and tacrolimus. In this study, we assess the frequency and clinical and imaging characteristics of PRES after SOT.Materials and methodsWe identified 27 patients (13 men and 14 women; age range, 22-72 years) who developed PRES after SOT. Features noted included SOT subtype, incidence and timing of PRES, infection and rejection, mean arterial pressure (MAP), and toxicity brain edema.ResultsPRES developed in 21 (0.49%) of 4222 patients who underwent transplantation within the study period (no significant difference among SOT subtypes). Transplantation was performed in 5 patients before the study period, and 1 patient underwent transplantation elsewhere. In consideration of all 27 patients, PRES typically developed in the first 2 months in patients who had SOT of the liver (9 of 10 patients) and was associated with cytomegalovirus (CMV), mild rejection, or systemic bacterial infection. PRES also typically developed after 1 year in patients who had SOT of the kidney (8 of 9 patients) and was associated with moderate rejection or bacterial infection. Toxicity MAP was significantly lower (P < .001) in liver transplants (average MAP, 104.8 +/- 16 mm Hg) compared with that in kidney transplants (average MAP, 143 +/- 20 mm Hg). Toxicity brain edema was significantly greater (P < .001) in patients who had liver transplants and developed PRES compared with patients who had undergone kidney transplants despite severe hypertension in those who had the kidney transplants.ConclusionPatients who had undergone SOTs have a similar low incidence of developing PRES. Differences between those who have had liver and kidney transplants included time after transplant, toxicity MAP, and PRES vasogenic edema noted at presentation. In patients who have undergone kidney transplants, severely elevated MAP was associated with reduced, not greater, brain edema.

Project description:Posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS) are relatively uncommon neurological disorders, but their detection has been increasing mainly due to clinical awareness and spreading of magnetic resonance imaging (MRI). Because these syndromes share some common clinical and radiologic features and occasionally occur in the same patient, misdiagnosis may occur. PRES is characterized by varied neurological symptoms including headache, impaired visual acuity or visual field deficit, confusion, disorders of consciousness, seizures, and motor deficits often associated to peculiar neuroradiological pattern even if uncommon localization and ischemic or hemorrhagic lesions were described. RCVS is a group of diseases typically associated with severe headaches and reversible segmental vasoconstriction of cerebral arteries, often complicated by ischemic or hemorrhagic stroke. Pathophysiological basis of PRES and RCVS are still debated but, because they share some risk factors and clinical features, a possible common origin has been supposed. Clinical course is usually self-limiting, but prognosis may fluctuate from complete recovery to death due to complications of ischemic stroke or intracranial hemorrhage. Neuroradiological techniques such as digital angiography and MRI are helpful in the diagnostic pathway and a possible prognostic role of MRI has been suggested. This review will serve to summarize clinical, neuroradiological features and controversies underlying both syndromes that may mislead the diagnostic pathway and their possible relationship with pathophysiology, clinical course, and prognosis.
