Neuroanatomical correlates of macrostructural receptive abilities in narrative discourse in unilateral left hemisphere stroke: A behavioural and voxel-based morphometry study.

Background: Little is known about story retelling and comprehension abilities in groups with lower levels of education and socio-economic status (SES). A growing body of evidence suggests the role of an extended network supporting narrative comprehension, but few studies have been conducted in clinical populations, even less in developing countries.

Aims: To extend our knowledge of the impact of a stroke on macrostructural aspects of discourse processes, namely main and complementary information, in individuals with middle-low to low SES and low levels of education.

Macrostructural Aspects in Oral Narratives in Brazilian Portuguese by Left and Right Hemisphere Stroke Patients With Low Education and Low Socioeconomic Status.

Objective: Individuals with a stroke in either the left hemisphere (LH) or the right hemisphere (RH) often present macrostructural impairments in narrative abilities. Understanding the potential influence of low education and low socioeconomic status (SES) is critical to a more effective assessment of poststroke language. The first aim was to investigate macrostructural processing in low-education and low-SES individuals with stroke in the LH or RH or without brain damage.

Vascularization of the uncus - Anatomical study and clinical implications.

Background: The objective of this paper was to describe the arterial supply of the uncus and quantify the branches directed to the anteromedial aspect of the human temporal cortex.

Methods: We studied 150 human cerebral hemispheres identifying main afferent arteries supplying the anteromedial temporal cortex with particular attention to the uncus, determining the territory supplied by each artery through either cortical or perforating branches.

Results: The uncus was supplied by 419 branches of the anterior choroidal artery (AChA), 210 branches of the internal carotid artery (ICA), 353 branches of the middle cerebral artery (MCA), and 122 branches of the posterior cerebral artery (PCA).

Neuroanatomical Correlates of Macrolinguistic Aspects in Narrative Discourse in Unilateral Left and Right Hemisphere Stroke: A Voxel-Based Morphometry Study.

Background A growing body of literature has demonstrated the importance of discourse assessment in patients who suffered from brain injury, both in the left and right hemispheres, as discourse represents a key component of functional communication. However, little is known about the relationship between gray matter density and macrolinguistic processing. Purpose This study aimed to investigate this relationship in a group of participants with middle-low to low socioeconomic status.

Posterior reversible encephalopathy syndrome (PRES): Is DWI a prognosis factor?

Introduction: Posterior reversible encephalopathy syndrome is a clinicoradiologic entity with typical MR imaging showing a white matter vasogenic edema predominantly affecting the occipital and parietal lobes of the brain. The aim of this article is evaluated the importance of DWI as a prognosis factor in patients with PRES.

Materials And Methods: We reviewed data from 70 patients with PRES (35 with restricted DWI and 35 with no DWI abnormalities), that were admitted to Hospital São Lucas-PUCRS.

Reversible hemianopsia in postpartum due to posterior reversible encephalopathy syndrome in pregnant with late eclampsia.

Objectives: To describe a case of Posterior Reversible Encephalopathy Syndrome diagnosed in pregnant women with late-eclampsia, as well as its clinical management.

Case Description: A 34 years old patient in her third pregnancy had started with high blood pressure levels during labor; after eleven days postpartum, she presented a decreased right visual acuity; subsequently one episode of seizure followed by partial loss of vision in the right eye. After conducting tests and ruled out stroke, the patient was diagnosed as Posterior Reversible Encephalopathy Syndrome (PRES).

Posterior Reversible Encephalopathy Syndrome: Clinical Differences in Patients with Exclusive Involvement of Posterior Circulation Compared to Anterior or Global Involvement.

Introduction: Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiologic syndrome not yet fully understood and characterized by transient neurologic symptoms in addition to typical radiological findings. There are only a few articles that describe the clinical differences between patients with PRES that involve carotid and vertebrobasilar circulations. Our study aims to further evaluate the differences between predominantly anterior and posterior circulation PRES.

Holmes' tremor as a delayed complication of thalamic stroke.

Movement disorders are not commonly associated with stroke. Accordingly, thalamic strokes have rarely been associated with tremor, pseudo-athetosis and dystonic postures. We present a 75-year-old man who developed a disabling tremor 1 year after a posterolateral thalamic stroke.

Ocular myositis: insights into recurrence and semiological presentation.

Ocular myositis (OM) is a rare clinical entity characterized by idiopathic, nonspecific inflammation of primarily or exclusively extraocular muscles (EOM). Presentation usually encompasses painful diplopia, exacerbated by eye movement. We report two cases of idiopathic OM with unique characteristics.

Posterior reversible encephalopathy syndrome: differences between pregnant and non-pregnant patients.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiologic entity not yet understood, that presents with transient neurologic symptoms and particular radiological findings. Few papers show the differences between pregnant and non-pregnant patients. We review the cases of 38 women diagnosed with PRES, in order to find significant differences between pregnant (18) and non-pregnant (20) patients.

Gemcitabine monotherapy associated with posterior reversible encephalopathy syndrome.

Posterior reversible encephalopathy syndrome is a clinicoradiologic entity that may present with headaches, altered mental status, seizures and visual loss as well as specific neuroimaging findings. We report a case of a 74-year-old woman receiving adjuvant gemcitabine chemotherapy as monotherapy for a stage IIa pancreatic adenocarcinoma, who developed posterior reversible encephalopathy syndrome.

Chronic syphilitic aortic aneurysm complicated with chronic aortic dissection.

Background: Historically, tertiary syphilis infection has been the most common cause of thoracic aortic aneurysm, resulting in 5% to 10% of cardiovascular deaths until the era of antibiotics.

Methods: A 49-year-old Caucasian man presented to our institution with progressive dysphagia, weight loss, incomplete bladder emptying, alcohol and tobacco consumption, systemic arterial hypertension, Argyll Robertson pupil, leg paresthesias, and mediastinal widening. He was admitted to investigate clinical alterations.
