Primary central nervous system tumors in Sergipe, Brazil: descriptive epidemiology between 2010 and 2018.

Background: Central nervous system (CNS) tumors are a heterogeneous group with high morbidity and mortality.

Objectives: To describe the epidemiology of primary CNS tumors diagnosed in the state of Sergipe from 2010 to 2018.

Methods: We evaluated histopathological and immunohistochemical reports on primary CNS tumors diagnosed in Sergipe, Brazil, between 2010 and 2018 and collected data regarding age, sex, location, World Health Organization (WHO) classification and histology.

Fisher revised scale for assessment of prognosis in patients with subarachnoid hemorrhage.

Unlabelled: The Fisher revised scale (FRS) presents an alternative for evaluating patients with subarachnoid hemorrhage (SAH). In this study, we compared the prognosis of patients with SAH and vasospasms (VSP).

Method: This was a prospective study on patients with a diagnosis of aneurysmal SAH, 72 hours after the initial event.

Development of a new experimental model of saccular aneurysm by intra-arterial incubation of papain in rabbits.

Introduction: Experimental saccular aneurysms can be created with surgical techniques of the arterial wall or by injecting pancreatic elastase. Papain is an enzyme with properties similar to those of elastase, and it has not been tested for this purpose. The objective of this study was to determine whether papain produces saccular aneurysms.

Clinical description of hemodialysis headache in end-stage renal disease patients.

Background: Hemodialysis (HD)-related headaches are a common complaint of patients undergoing this procedure.

Objective: To determine the frequency and clinical characteristics of headache in patients undergoing HD and to discuss their diagnostic criteria.

Method: The present study assessed, in a prospective manner, a series of patients consulting at a HD center in Aracaju, Sergipe, Brazil, from November 2007 to January 2008.

[Megalencephalic leukoencephalopathy with vanishing white matter and cystic formation].

We present three cases of megalencephalic leukoencephalopathy with vanishing white matter and cystic formation in both temporal lobes, diagnosed through magnetic resonance imaging. All the cases presented clinical and radiological aspects according to the diagnostic criteria that were established in the initial description of the syndrome. Clinical and radiological aspects are discussed.

[Circadian rhythm and encephalic vascular disease: a correlative study with risk factors].

The human biological mechanisms show a predictable clinical variability in time, which has allowed a deeper reevaluation of present-day medical practices, regarding the circadian rhythm (CR) and the mechanisms that produce the supported variations in all biological levels. We have made a study aiming to relate the CR and onset of the neurological clinic situation due to the encephalic vascular lesion, correlating with modifying risk factors. Fifty three patients were studied, 50,94% female (n=27) and 49,50% male (n=26), at average age 66.

[Anatomical and functional abnormalities of central nervous system in autistic disorder: a MRI and SPECT study].

We present a study of anatomical and functional abnormalities of central nervous system (CNS) from patients with autistic disorder (AD); magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) were used for the investigation. The population studied was composed of 24 patients, 15 (62.5%) males and 9 (17.
