RESUMO

RESUMEN En muchas ocasiones, los pacientes con tumores cerebrales tienen una variedad de síntomas psiquiátricos inespecíficos. Algunos de estos pueden constituir la primera o única manifestación del tumor, sin la presencia de ningún síntoma o signo neurológico. El diagnóstico ha de basarse en la anamnesis completa y en la exploración neurológica; la neuroimagen confirmará el diagnóstico clínico. Con el presente trabajo se describió la asociación inusual de hematoma subdural crónico y meningioma parasagital en un caso presentado. Se trató de un paciente de 68 años con antecedentes de esquizofrenia. Acudió a consulta con una hemiparesia izquierda. Se le realizó una tomografía axial computarizada de cráneo y arrojó un hematoma subdural crónico y un meningioma parasagital derecho. Se le aplicó tratamiento quirúrgico en dos tiempos operatorios. Su evolución posquirúrgica transcurrió sin complicaciones (AU).

ABSTRACT In many cases, patients with brain tumors have a variety of nonspecific psychiatric symptoms. Some of them can be the first or the only manifestation of the tumor, without presenting any neurological signs or symptoms. The diagnosis must be based on the complete anamnesis and on the neurological examination. The neuroimaging will confirm the clinical diagnosis. The unusual association of a chronic subdural hematoma and a parasagittal meningioma was described in a case presented in the current work. It dealt with a patient, aged 68 years with antecedents of schizophrenia. He assisted the consultation with left hemiparesis. A skull computed tomography showed a chronic subdural hematoma and a right parasagittal meningioma. He underwent a two-steps surgery. His post-surgery evolution ran without complications (AU).

RESUMO

Introduction Chronic subdural hematoma (CSH) is one of the most frequent forms of intracranial hemorrhage. It is a collection of encapsulated, well-delimited fluid and/or coagulated blood in several clotting stages located between the dura mater and the arachnoid mater. Objective To describe the epidemiological aspects of CSH described in the database of the Brazilian Unified Health System (SUS, in the Portuguese acronym) regarding admission numbers, hospitalization expenses, health care professional expenses, mortality rate, and death numbers by region from 2008 to the first half of 2016. Methods The present work was performed between August and September 2016 with a review about the epidemiological aspects of CSH in Brazil according to the Informatics Department of the Unified Health System (DATASUS) database, encompassing the period from January 2008 to June 2016, and to scientific papers from the past 10 years which were electronically published at the PubMed, Scielo, and LILACS databases. Results From 2008 to the first half of 2016, the total values were the following: hospital admission authorizations (HAAs). 33,878; hospital expenses, BRL 65,909,429.22; health care professional expenses, BRL 25,158,683.21; deaths, 2,758; and mortality rates ranging from 6.47 to 12.63%. Conclusion In spite of the high clinical relevance of CSH, epidemiological studies about this condition are limited. As such, the present paper is an updated approach on CSH, focusing on its epidemiological aspects according to the DATASUS database.

RESUMO

OBJECTIVE: To characterize patients with chronic subdural hematoma undergoing surgery and to identify prognostic indicators. METHODS: We conducted a retrospective analysis of patients diagnosed with chronic subdural hematoma (CSDH) undergoing surgical treatment. We analyzed: age, period from trauma to diagnostic imaging, pre and postoperative Glasgow coma scale, type of surgery, associated comorbidities, use of postoperative drainage and outpatient treatment. RESULTS: The sample consisted of 176 patients, 126 male and 50 female patients (ratio 2.5 : 1), ages ranged from six months to 97 years, with an average of 59.3 years. CSDH was caused by trauma in 52% of patients, with the time from trauma to imaging averaging 25.05 days; 37.7% were hypertensive patients and 20% had a neurological disease. Eighty-five (48.3%) patients were elderly and altered consciousness was present in 63% of cases. Of the 91 (51.7%) non-elderly patients, 44% presented with headache, altered consciousness occurred in 40% and motor abnormalities in 27.5%. The CSDH was located on the right in 41%, left in 43% and bilaterally in 16% of patients. CONCLUSION: the change of consciousness was the most common clinical alteration in the elderly and headache in non-elderly. The most associated comorbidity was the arterial hypertension and the most frequent cause, head trauma. The trepanation with two oriffices associated with a closed drainage system was the most used operating, with high efficacy and low complication rate.

RESUMO

BACKGROUND: Chronic subdural hematomas (CSDHs) are common in neurosurgical practice. There are no publications that report large series of the epidemiological characteristics of this pathology in Brazil. The purpose is to describe a large series of surgical cases and analyze the epidemiological and clinical characteristics. METHODS: We retrospectively analyzed patients with CSDH admitted into Neurosurgical Services at the Hospital de Base do Distrito Federal, Brasília, Brazil from 2006 to 2011. Age, sex, clinical feature, etiology, surgical procedure, side, clinical outcome, and recurrence were reviewed. Statistical tests were used to analyze data, and P < 0.05 was considered statistically significant. RESULTS: The series included 778 patients. There were 643 (82.6%) male patients with a mean age of 64.3 ± 15.9 (range, 14-93) years. The principal symptom was headache (58.9%). The most frequent origin was a fall (282 cases, 36.2%), but the origin remained unclear in 281 (36.1%) patients. Mild head injury occurred in 540 (69.4%) cases. Burr holes with drainage were used as the surgical procedure in 96.5% patients, and 687 (88.3%) patients had a positive outcome. Mortality was 0%. Recurrence was observed in 42 cases. CONCLUSIONS: The occurrence of CSDHs is more common in elderly men. Treatment with burr holes and drainage is a simple and safe method for treatment. In our experience, CSDH presents decreased morbidity and mortality.

RESUMO

OBJECTIVE: We sought to identify risk factors for mortality in a large clinical cohort of children with abusive head trauma. STUDY DESIGN: Bivariate analysis and multivariable logistic regression models identified demographic, physical examination, and radiologic findings associated with in-hospital mortality of children with abusive head trauma at 4 pediatric centers. An initial Glasgow Coma Scale (GCS) ≤ 8 defined severe abusive head trauma. Data are shown as OR (95% CI). RESULTS: Analysis included 386 children with abusive head trauma. Multivariable analysis showed children with initial GCS either 3 or 4-5 had increased mortality vs children with GCS 12-15 (OR = 57.8; 95% CI, 12.1-277.6 and OR = 15.6; 95% CI, 2.6-95.1, respectively, P < .001). Additionally, retinal hemorrhage (RH), intraparenchymal hemorrhage, and cerebral edema were independently associated with mortality. In the subgroup with severe abusive head trauma and RH (n = 117), cerebral edema and initial GCS of 3 or 4-5 were independently associated with mortality. Chronic subdural hematoma was independently associated with survival. CONCLUSIONS: Low initial GCS score, RH, intraparenchymal hemorrhage, and cerebral edema are independently associated with mortality in abusive head trauma. Knowledge of these risk factors may enable researchers and clinicians to improve the care of these vulnerable children.

RESUMO

The lack of specificity and heterogeneity of the clinical picture of chronic subdural hematoma, hampers its diagnosis. Aim: To report the experience of a Neurosurgical Service in chronic subdural hematoma. Patients and methods: One hundred patients (77 male, mean age 77ñ13 years) with chronic subdural hematoma were analyzed. Results: The main clinical presentations were mental status changes (50 percent) and progressive focal neurological deficit (46 percent). Five cases presented as a transient neurological deficit. All patients were treated with burr hole drainage. Thirteen had recurrence of the hematoma and they were reoperated. The surgical mortality was 3 percent. Eighty seven patients were followed for a mean of 66 months. Eighty one of these had a complete recovery, 6 had permanent neurological deficit and 2 of these were unable to care for themselves. Bad prognosis was associated with the absence of a previous trauma to explain the hematoma and symptoms of dementia as the clinical presentation. Conclusions: Most patients with chronic subdural hematoma treated with burr hole drainage have a good outcome

RESUMO

INTRODUCTION: Although chronic and subacute subdural haematomas (CSSH) are amongst the commonest neurosurgical conditions, there are few studies on their incidence in the general population. OBJECTIVES: To determine the overall annual rate, the specific rates according to age and sex based on the Official Argentinian National Census of 1991 (OANC 91) for CSSH. PATIENTS AND METHODS: The Hospital Privado de Comunidad de Mar del Plata attends a captive population of 89,500 persons from the Instituto Nacional de Servicios Sociales de Jubilados y Pensionados (INSSJP) and the Prepaid Medical Schemes (PMP) of our institution. We studied the patients of INSSJP and PMP who had CSSH between 1992 and 1996. We determined the annual overall rate and the specific rates according to age and sex, and fitted to the OANC 91. RESULTS: 1. Annual overall rate: 14.1 CSSH/100,000 persons/year. 2. Specific rate for women: 11.6 CSSH/100,000 persons/year. 3. Specific rate for men: 18.1 CSSH/100,000 persons/year. 4. Specific rate 71-80 years old: 18.8 CSSH/100,000 persons/year. 5. Rate fitted to OANC9: 3.1 CSSH/100,000 persons/year. CONCLUSIONS: Our overall rate is higher, and the specific rate for the age group 71-80 years is intermediate, with regard to the rates found in other studies. Neuroepidemiological investigation should be stimulated so that more clinical studies are made regarding the results and costs based on the population.
