Caracterización epidemiológica: descripción de mortalidad para hemorragia subdural aguda no traumática en el período 2017-2021, en Chile / Epidemiological characterization: description of mortality for non-traumatic acute subdural hemorrhage in the 2017-2021 period, in Chile

Introducción: La hemorragia subdural aguda no traumática (HSDNT) es una patología relacionada a factores de riesgo cardiovascular (RCV). Por falta de estudios epidemiológicos nacionales, se plantea estudiar la tasa de mortalidad (TM) y defunciones por HSDNT entre los años 2017-2021 en Chile. Metodología: Estudio descriptivo, transversal, sobre defunciones por HSDNT entre los años 2017-2021 en Chile (N=878), según grupo etario, sexo y lugar de defunción, usando datos obtenidos del departamento de estadística e información en salud. Se utilizó estadística descriptiva y cálculo de TM. No requirió aprobación por comité de ética. Resultados: Se calculó una TM de 0,99/100.000 habitantes entre los años 2017-2021, siendo la mayor los años 2017-2019 y 2020 con TM de 1/100.000. El sexo masculino presentó TM de 1,27/100.000, el grupo etario mayor a 80 años presentó una TM de 19,28/100.000 habitantes. Según lugar de defunción, el año 2020 un 83% (148) de las defunciones fue en hospital o clínica. Discusión: La prevalencia del RCV hace relevante el estudio de mortalidad por HSDNT, donde la principal hipótesis de su mortalidad en Chile estaría basada en estos factores riesgo latentes. Según lugar de defunción, se podría suponer dadas mayores complicaciones en aquellos pacientes hospitalizados por HSDNT. Conclusión: Dada la nula existencia de datos sobre esta patología en Chile, se realizó una caracterización epidemiológica en conjunto a un análisis de defunciones según el lugar, aportando una perspectiva nacional de mortalidad sobre este cuadro en particular.

Introduction: Non-traumatic acute subdural hemorrhage (NTSDH) is related to cardiovascular risk factors (CVR). Due to lack of national epidemiological studies, it is proposed to study mortality rate (MR) and deaths from HSD between the years 2017-2021 in Chile. Methodology: Descriptive, observational, cross-sectional study on deaths due to SDH between the years 2017-2021 in Chile (N=878), in a population older than 15 years, according to age group, sex and place of death, using data obtained from Departamento de estadísticas e información en salud. Descriptive statistics and MR calculation were used. It did not require approval by an ethics committee. Results: A MR of 0.99/100,000 inhabitants was calculated between the years 2017-2021, the year being the highest in the years 2017-2019 and 2020 with MR of 1/100,000. Male sex presented a MR of 1.27/100,000, the age group over 80 years presented a MR of 19.28/100,000 inhabitants. By place of death, in 2020 there were 148 deaths in hospitals or clinics. Discussion: The prevalence of CVR makes the study of mortality from NTSDH relevant, where the hypothesis of its mortality in Chile would be based on these risk factors. Depending on the place of death, it could be assumed that there are greater complications in those patients hospitalized for NTSDH. Conclusion: Given the null existence of data on this pathology in Chile, an epidemiological characterization was carried out together with an analysis of deaths according to the place, providing a national perspective of mortality about this disease.

Parche de sangre cervical para tratamiento de síndrome de hipotensión/ hipovolumen de líquido cefalorraquídeo espontáneo. Reporte de un caso / Cervical blood patch for the treatment of spontaneous cerebrospinal fluid hypotension/hypovolume syndrome. A case report

Presentamos el tratamiento eficaz de una filtración espontánea de líquido cefalorraquídeo (LCR) asociada a un síndrome de hipoten-sión/hipovolumen de LCR a nivel cervical alto, caracterizado por delirio y hematomas subdurales secundarios, refractarios al drenaje quirúrgico, que se resolvió con dos parches de sangre epidurales cervicales consecutivos.

We present the case of a cerebrospinal fluid (CSF) hypotension/hypovolume syndrome due to a spontaneous CSF fistula at the upper cervical level characterized by loss of consciousness and bilateral subdural hematomas refractory to two drainage surgeries that resolved with two consecutive blood patches on the leak site.

Silent killer presenting as isolated oculomotor nerve palsy

Head trauma can result trivial to life threatening manifestations to a person. Subdural hemotomais characterised by accumulation of blood in subdural space, in most cases it is a serious condition and requires prompt diagnosis and treatment for the same to provide good outcome. Large collection, mid line shift, brain herniation associated with subdural hematoma is associated with increased morbidity and mortality. However, if the collection is minimal or is places like tentorium cerebelli may not have the typical presentation and if it抯 picked up using the subtle signs the devastating sequelae can be prevented. We report a 19 years old male with head trauma presenting with features of right-side isolated oculomotor nerve palsy who eventually found to have tentorial subdural hemotoma in imaging which has been intervened and complications were avoided.

A 44-year-old male Filipino with Spontaneous Acute Subdural Hematoma and Subarachnoid Hemorrhage caused by a Dural Arteriovenous Fistula of the Occipital Lobe: A case report

Introduction@#Spontaneous acute subdural hematoma (ASDH) is rare and comprises 2.6% of all ASDH. In one recent study, only 178 spontaneous ASDH were documented. However, only 1 case was attributed to dural arteriovenous fistula (dAVF). Vascular malformations cause less than 10% of subarachnoid hemorrhage (SAH). Spontaneous ASDH and SAH occurring together are extremely rare. Literature is scarce on cases with dAVF of the occipital lobe as a cause of simultaneous spontaneous ASDH and SAH. @*Objective@#This paper aims to present a case of a spontaneous acute subdural hematoma and subarachnoid hemorrhage caused by a dural arteriovenous fistula of the occipital lobe, along with its clinical presentation, diagnosis, and treatment. @*Case Summary@#A 44-year-old Filipino male with no history of trauma presented with severe headache, vomiting, and decreasing sensorium – CT scan revealed acute parenchymal bleed in the left occipital lobe with subarachnoid extension and subdural hematoma in the left fronto-parieto-temporal convexity along the tentorium cerebelli and posterior interhemispheric falx. Due to the location of the lesion seen on the CT scan and the gender distribution, Arteriovenous malformation (AVM) was initially considered, thus proceeded to computed tomography angiogram (CTA) to establish the diagnosis of vascular anomaly, however, revealed dAVF instead. Four-vessel angiogram was done to assess the tributaries of the dAVF and confirmed the diagnosis. Complete obliteration of dAVF of the occipital lobe was done with Onyx Embolization in one session. @*Conclusion@#This is the first case of Borden type II, Cognard type IIa+IIb dAVF, as reported in this institution. Although extremely rare as a cause of SAH and ASDH, dAVF should be considered a differential diagnosis in patients with no identifiable common cause of the new onset of severe headache and poor neurologic status.

Clinical feature analysis of subdural effusion/hematoma after shunt use of adjustable valves in children with hydrocephalus / 中华实用儿科临床杂志

Objective:To analyze the clinical data of children with hydrocephalus suffering from subdural effusion/hematoma after shunt(SEHS) with adjustable valves, and to provide reference for postoperative follow-up.Methods:A total of 102 children with hydrocephalus treated with adjustable valves in the Department of Neurosurgery, Wuhan Children′s Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from August 2017 to September 2021 were enrolled and studied retrospectively.There were 16 cases with SEHS, 11 of whom were male and 5 were female.The age ranged from 3 months to 13 years (median: 2.5 years). The age, clinical manifestations, the time of SEHS occurrence, treatment methods(pressure regulation only or combined with drilling and drainage), and prognosis of the patients were analyzed.The pressure adjustment treatment was to increase the by 10-20 mmH 2O (1 mmH 2O=0.009 8 kPa) each time and the patients were followed up 2-4 weeks after the adjustment.If SEHS didn′t improve according to the follow-up results, pressure regulation combined with drilling and drainage was recommended. Results:Of the 16 patients with SEHS, 3 cases were over 3 years old, and the other 13 cases were 3 years old or below.Eleven cases were treated by pressure regulation only, and 5 cases who were all aged ≤3 years received pressure regulation combined with drilling and drainage.Symptoms occurred in 2 patients, including vomiting in 1 case, and head and limb shaking in the other case.Fourteen cases were asymptomatic.The time from shunt operation to the occurrence of SEHS was ≤1 month in 5 cases, who were all cured by pressure regulation only.SEHS occurred in 5 cases >1-3 months after shunt surgery, and 2 cases of them were treated by pressure regulation combined with dri-lling and drainage.Three cases had SEHS>3-6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.SEHS occurred in 3 cases more than 6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.For the patients who received pressure regulation combined with drilling and drainage, the time from shunt operation to the occurrence of SEHS was 1 month and 21 days, 2 months and 7 days, 4.5 months, 7.5 months, and 25.0 months, respectively.The time from the occurrence of SEHS to the last reexamination with no SEHS detected was ≤1 month in 7 cases (all were cured by pressure regulation only); >1-3 months in 5 cases (3 cases were treated by pressure regulation combined with drilling and drainage); more than 3 months in 4 cases (2 cases were treated by pressure regulation combined with drilling and drainage). For the patients who received pressure regulation combined with drilling and drainage, the time from the occurrence of SEHS to the last reexamination with no SEHS detected was 1 month and 14 days, 2.0 months, 3.0 months, 7.0 months and 8.0 months, respectively.Except for 2 cases who experienced pressure regulating valve failure, all other cases were cured.Six cases were unilateral SEHS, and the SEHS volume was about 11 to 75 mL (median: 39.0 mL). Ten cases were bilateral SEHS, and the SEHS volume was about 23-380 mL (median: 158.2 mL). The 6 cases were all cured by pressure regulation, and 5 cases of them had SEHS at the shunt tube insertion side.Conclusions:SEHS in children with hydrocephalus is generally asymptomatic and rarely causes clinical symptoms.SEHS mostly occurs within 6 months after operation, especially within 3 months.SEHS found in 1 month after surgery can be cured by increasing the shunt valve pressure only.Therefore, SEHS can be cured by pressure regulation only by shortening follow-up and identifying SEHS early after shunt operation.This will also reduce the probability that patients require the drilling and drainage operation.

Subdural hematoma following lumbar spine surgery

Abstract The occurrence of subdural hematomas following lumbar spine surgical procedures is a rare complication, but one with a high burden of morbidity and mortality, and despite an incidence rate of around 1%, it is a complication which must be considered in this group of patients. We present the case of a male patient, in the fourth decade of life, with a history of neurofibromatosis and spastic quadriparesis, who developed an altered state of consciousness following lumbar tumor resection, ending in a coma. A simple cranial CAT showed evidence of an acute right subdural hematoma which had to be drained via a craniotomy. He had an unsatisfactory postoperative course and died in the intensive care unit due to ARDS. The national literature has little information on this complication, therefore we believe that this case is an important contribution to the literature. (Acta Med Colomb 2021; 46.

Meningioma parasagital y hematoma subdural crónico, una asociación inusual / Parasagittal meningioma and chronic subdural hematoma, unusual association

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).

Hematoma subdural crónico / Chronic subdural hematoma

El hematoma subdural crónico (HSC) es una patología neuroquirúrgica frecuente, que se reconoce como consecuencia de traumatismos craneoencefálicos de poca magnitud que habitualmente se diagnostican en pacientes seniles, aunque puede presentarse en pacientes jóvenes y sin antecedentes de traumas.El objetivo que persigue este trabajo es la presentación de una paciente con un HSC bilateral, con características poco usuales.Caso clínico: se presenta una paciente del sexo femenino, de 46 años de edad, sin antecedente de traumatismo craneal ni de otra patología concomitante, que consulta por una cefalea de 15 días de evolución. El examen físico constató midriasis, pupila de Hutchinson, papiledema bilateral y exoforia del ojo derecho, parálisis del tercer par craneal y ataxia de tronco, fue catalogada con Glasgow 13. Se realizó tratamiento anti edema cerebral temprano y las manifestaciones desaparecieron en gran medida. En la Tomografía axial computarizada se diagnosticó un hematoma subdural frontotemporal bilateral con desplazamiento de las estructuras de la línea media a la izquierda. Fue operada de urgencia y dada de alta completamente recuperada tres días después.Conclusión: el HSC puede presentarse con distintas formas clínicas, simulando procesos expansivos tumorales, ataques cerebrovasculares, demencias o entidades neurológicas de otra índole. El manejo del caso por clínicos y neurocirujanos fue rápido y efectivo, lo que explica que la paciente tuvo una recuperación temprana y total. En estos casos la actuación médica es decisiva en el éxito del tratamiento.

Chronic subdural hematoma (CSH) is a common neurosurgical pathology that is recognized as a consequence of minor head injuries that are usually diagnosed in senile patients, although it can occur in young patients without a history of trauma.The objective of this work is the presentation of a patient with a bilateral CSH, with unusual characteristics.Clinical case: a 46-year-old female patient with no history of head trauma or other concomitant pathology is presented, who consulted for a 15-day-old headache. Physical examination confirmed mydriasis, Hutchinson's pupil, bilateral papilledema and exophoria of the right eye, third cranial nerve palsy, and trunk ataxia. She was cataloged with Glasgow 13. Early anti-cerebral edema treatment was performed and the manifestations largely disappeared. A computed tomography scan diagnosed a bilateral fronto temporal subdural hematoma with displacement of the midline structures to the left. She underwent emergency surgery and was discharged completely recovered three days later. Conclusion: HSC can present with different clinical forms, simulating expansive tumor processes, cerebrovascular attacks, dementias or neurological entities of another nature. The case management by clinicians and neurosurgeons was quick and effective, which explains that the patient had an early and complete recovery. In these cases, medical action is decisive in the success of the treatment.

Casos clínicos sobre tratamiento conservador del hematoma subdural crónico / Clinical cases on conservative treatment of chronic subdural hematoma

Introducción: El hematoma subdural crónico es una de las entidades clínicas más comunes en la práctica neuroquirúrgica diaria, cuya incidencia y prevalencia aumentan considerablemente con la edad. El tratamiento conservador puede ser muy útil en algunos casos. Objetivo: Mostrar que el manejo farmacológico exclusivo de este padecimiento, puede ser considerado en muchos pacientes. Casos clínicos: Se presentan dos pacientes adultos mayores, atendidos en el servicio de Neurocirugía, con diagnóstico de hematoma subdural crónico, tratados solo con fármacos.

Conservative treatment can be very useful in many patients. Objective: To show that the exclusive pharmacological management of this condition can be considered in many patients. Clinical cases: Two elderly patients attended at the neurosurgery service are presented with a diagnosis of chronic subdural hematoma. They were treated only with drugs. Conclusions: The final result was the reabsorption of the subdural collections, which was proven by imaging studies(AU)

Meningeal Carcinomatosis for Prostate Adenocarcinoma Mimicking Chronic SubduralHematoma: Case Report and Literature Review

Introduction Cerebral metastases are the most common cancer of the central nervous system (CNS). Meningeal infiltration by neoplasms that did not originate in the CNS is a rare fact that is present in 0.02% of the autopsies. Epidemiologically, the radiological presentation mimicking a subdural hematoma is even more uncommon. We report a case of meningeal carcinomatosis by an adenocarcinoma of the prostate mimicking a chronic subdural hematoma. Case Report A 60-year-old male patient was diagnosed with prostate cancer in 2011. He underwent radical resection of the prostate, as well as adjuvant hormonal therapy and chemotherapy. Five years later, the patient presented peripheral facial paralysis that evolved with vomiting and mental confusion. Tomography and magnetic resonance imaging scans confirmed the subdural collection. At surgery, the dura was infiltrated by friable material of difficult hemostasis. The anatomicopathological examination showed atypical epithelial cells. The immunohistochemistry was positive for prostate-specific antigen (PSA) and other keymarkers, and it was conclusive for meningeal carcinomatosis by a prostate adenocarcinoma.

Factores pronósticos en el traumatismo craneoencefálico grave en pediatría / Prognostic factors in severe head injury in pediatrics

Objetivos: Analizar y establecer una asociación entre las características del Traumatismo Craneoencefálico (TEC) grave en pediatría (edad, etiología, características clínicas, lesiones intracraneales y cirugía) y los resultados a largo plazo. Material y Método: Revisión de los pacientes con TEC grave ingresados al Hospital Garrahan desde enero 2013 hasta enero 2019. Se analizaron las características al ingreso y el tratamiento instaurado. Se utilizó la escala Glasgow Outcome Scale (GOS) para evaluar los resultados a 12 meses. Se realizó un análisis estadístico mediante las pruebas de Chi2 y Fisher. Se consideró como significativo a un valor de p menor a 0.05. Resultados: Se registraron 54 pacientes con TEC grave y seguimiento posterior de 12 meses. La mediana de edad fue de 6 años (3-12). La mayoría fue de sexo masculino 62.96% (34). La etiología más frecuente fue la caída de altura (42.59%) mientras que la lesión intracraneal que más se observó fue el hematoma extradural (25.93%). Los factores que se asociaron a mal pronóstico fueron las lesiones no accidentales (100% vs 0%; p=0.02), la midriasis bilateral (100% vs 0%; p= 0.001) y el hematoma subdural (70% vs 30%; p= 0.002). Los factores asociados a buen pronóstico fueron las caídas de altura (54.84% vs 45.16%; p=0.01) y un examen oftalmológico normal al ingreso (90% vs 10%; p=0.006). Conclusión: Los factores que se asociaron a mal pronóstico fueron el trauma no accidental, la midriasis y el hematoma subdural agudo. Por otro lado, las caídas y el examen oftalmológico normal se asociaron a mejor pronóstico.

Objective: To analyze and establish an association between the characteristics of severe traumatic brain injury (TBI) in pediatric patients (age, etiology, clinical characteristics, intracranial injuries and surgery) and long-term results. Material and Method: Review of patients with severe TBI admitted to Garrahan Pediatric Hospital from January 2013 to January 2019. The characteristics of admission and treatment instituted were analyzed. The Glasgow Outcome Scale (GOS) was used to evaluate results at 12 months. A statistical analysis was performed using Chi2 and Fisher tests. A p value less than 0.05 was considered significant. Results: A total of 54 patients with severe TBI and subsequent follow-up of 12 month were reported. The median age was 6 years (3-12). Most were male 62.96% (34). The most common etiology was height falls (42.59%) while the most observed intracranial lesion was extradural hematoma (25.93%). Non-accidental injuries (100% vs 0%; p=0.02), bilateral mydriasis (100% vs 0%; p=0.001) and subdural hematoma (70% vs 30%; p=0.002) were associated with poor prognosis. Height drops (54.84% vs 45.16%; p=0.01) and a normal ophthalmological examination at income (90% vs 10%; p=0.006) were associated with good prognosis. Conclusion: Non-accidental trauma, mydriasis and acute subdural hematoma were associated with poor prognosis, whereas falls and normal eye exam were associated with better prognosis

Abducens Nerve Palsy as Initial Manifestation of Chronic Subdural Hematoma: Case Report

Chronic subdural hematoma (CSDH) is a form of progressive intracranial hemorrhage, typically associated with cases of trauma. The manifestation of this comorbidity with abducens palsy is a rare finding. The present work aims to describe the case of an adult patient with abducens nerve palsy as a manifestation of CSDH. Chronic subdural hematoma is most commonly found in elderly patients, with systemic hypertension as amanifestation. The relation with the sixth cranial nerve is unusual and draws attention to the case reported. In addition, the prognosis is positive, since trepanation and drainage surgery was performed, as it is recommended in the literature.

Hematoma subdural en pacientes alcohólicos / Subdural hematoma in alcoholicpatients / Hematoma subdural em pacientes alcoolizados

RESUMEN Un hematoma subdural es una acumulación de sangre entre la duramadre, que es la membrana que cubre el cerebro, y la aracnoides, una de las capas de las meninges; se debe a la rotura traumática de vasos venosos que atraviesan el espacio subdural, por lo tanto se produce una separación entra las capas de la aracnoides y la duramadre. El objetivo fue determinar el tipo de hematoma subdural en pacientes alcohólicos. Se realizó un estudio observacional descriptivo transversal, en el Hospital Provincial General Universitario Carlos Manuel de Céspedes, en el período de diciembre de 2017 a septiembre de 2018. La población de estudio fue de 13 pacientes alcohólicos que cumplieron con los criterios de inclusión. Predominó el grupo de 40 a 50 años con siete pacientes; el 53,84 % de los estudiados presentaron hematoma subdural agudo, y el lado del cerebro más afectado fue el izquierdo con el 46,15 %. Se concluye que el hematoma subdural agudo, con afectación del lado izquierdo del cerebro, es más frecuente en los pacientes alcohólicos.

ABSTRACT A subdural hematoma is a collection of blood between the duramater, which is the membrane that covers the brain, and the arachnoid, one of the layers of the meninges; it is due to the traumatic rupture of venous vessels that cross the subdural space, therefore a separation takes place between the layers of the arachnoid and the duramater. The objective was to determine the type of subdural hematoma in alcoholic patients. An observational cross-sectional descriptive study was carried out in the General University Provincial Hospital Carlos Manuel de Céspedes, in the period from December 2017 to September 2018. The population studied 13 alcoholic patients who met the criteria of inclusion. The group of 40 to 50 years with seven patients predominated; 53, 84% of those studied had acute subdural hematoma, and the most affected side of the brain was the left which represents the 46, 15%. It is concluded that the acute subdural hematoma, with involvement of the left side of the brain, is more frequent in alcoholic patients.

RESUMO Um hematoma subdural é um acúmulo de sangue entre a dura-máter, que é a membrana que cobre o cérebro e o aracnóide, uma das camadas das meninges; É devido à ruptura traumática dos vasos venosos que atravessam o espaço subdural, portanto ocorre uma separação entre as camadas do aracnóide e da dura-máter. O objetivo foi determinar o tipo de hematoma subdural em pacientes alcoolizados. Foi realizado um estudo observacional descritivo transversal no Hospital Provincial Geral da Universidade Carlos Manuel de Céspedes, no período de dezembro de 2017 a setembro de 2018. A população do estudo foi de 13 pacientes alcoolistas que preencheram os critérios de inclusão. O grupo de 40 a 50 anos predominou com sete pacientes; 53,84% dos estudados apresentaram hematoma subdural agudo, e o lado do cérebro mais afetado foi o esquerdo com 46,15%. Conclui-se que o hematoma subdural agudo, com envolvimento do lado esquerdo do cérebro, é mais frequente em pacientes alcoolizados.

Geriatric head injuries: impact and outcomes

Background: Elderly trauma patients present unique challenges and face  more  significant obstacles in  recovery  than  their younger  counterparts. They usually experience higher morbidity and mortality and slower recovery trajectories and have, on average, worse functional, cognitive, and psychosocial outcomes months or years post-injury than do younger patients.Methods: Authors conducted a study of elderly head injury patients to understand the epidemiology of geriatric TBI, the impact of comorbidities and management issues and  outcomes in such patients. Authors had a total of 110 patients who presented with traumatic brain injury and were admitted in this hospital over 2 years. Authors also reviewed the literatures to study the factors affecting outcome after geriatric TBI and studied the role of aggressive neurosurgical management in geriatric TBI.Results: Among 68%(n=75) of the patients were male and 32% females. Age group of 60-65 years was the highest with 60.9% patients. Patients with GCS of 8 and below had the highest mortality rates of 68 %. Overall  mortality  rate  was  32.72%  and  9.09 %  of  the patients survived in a vegetative condition. The proportion of injury secondary to fall was the largest single group in 50.9% patients, and Chronic SDH was the most common pathology seen in 36.45 % patients. Highest mortality was seen in patients with Diffuse Axonal Injury (69.23 %). Out of the 110 patients , 57 patients underwent surgery for various pathologies. Chronic SDH were the most common operated pathology followed by acute SDH. Glassgow outcome scale was used as the measure of outcome in these series of patients.  32.72 % patients had a GOS score of 1 and 9.09 % had a score of 2. 18.18 % patients remained severely disabled with a score of 3 and nine patients (8.18 %) had a score of 4 and thirty five patients had good recovery (GOS-5).Conclusions: Due to the better treatment options there is an increase in the number of elderly around the world. Thus, the number of eldery individuals presenting with TBI to the emergency department is also on the rise more commonly due to falls than road traffic accidents. There is a need for specific prognostic and management guidelines for the elderly which can lead to better diagnosis, care and recovery and eventual short- and long-term outcomes in the elderly.

Intracranial Subdural Hematoma after Spinal Anesthesia: Report of Two Cases with different Outcomes

Spinal anesthesia is a technique commonly used for local anesthesia and in obstetric surgeries. Rarely, the formation of an intracranial subdural hematoma (SDH) may result from spinal anesthesia, constituting a serious condition that often leads to severe neurological deficits. The presentation and course of this pathology may occur in a completely different way, which makes its diagnosis and management difficult. In the present article, the authors report two cases of patients with intracranial SDH after spinal anesthesia with completely different presentations and outcomes, demonstrating the variability of the manifestations of this condition. A quick review of key points of its pathophysiology, symptomatology, diagnosis, and treatment was also performed.

Epidemiology and Estimated Cost of Surgery for Chronic Subdural Hematoma Conducted by the Unified Health System in Brazil (2008­2016)

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.

Spontaneous subdural hematoma in a multigravida with chronic kidney disease and superadded pre-eclampsia detected by MRI: a case report

Chronic kidney disease and pre-eclampsia are both known individual culprits for significant morbidity and mortality of mother and child worldwide. Non traumatic spontaneous subdural hematoma in pregnancy is a rare scenario, however stage 5 chronic kidney disease with superadded pre-eclampsia can be contributory factor for spontaneous extra axial bleed. Our patient was 25-year-old with history of end stage renal disease and chronic hypertension admitted with superadded pre-eclampsia. She had 1 living issue and 2 stillbirths. There was sudden deterioration of mental status as well as motor performance, the patient turned stupurous and was not following verbal commands. Patient was sent for MRI evaluation of brain and diagnosed as right sided subdural hematoma with significant midline shift towards the contralateral side. No intraparenchymal haemorrhage was noted.

Subdural Hematoma following Accidental Dural Puncture while Performing Epidural Analgesia - A Case Report

Introduction: Subdural hematoma is a rare but seriouscomplication of accidental dural puncture during epidural orspinal anesthesia. This case report emphasizes the importanceof close follow-up of patients with post dural punctureheadache following accidental dural puncture and methods toidentify development of subdural hematoma in such patients.Case report: a 23-year-old healthy primigravida developedaccidental dural puncture while trying to locate epiduralspace using a Tuohy needle for painless labor. The patientcomplained of headache on the 2nd post-operative day that wassignificantly relieved by analgesics, bed rest and hydration.Later she presented with severe headache that becamepersistent and lost its correlation with change of posture.Other than feeling nauseated she had no other additional signsand symptoms. Diagnosis of the SDH was confirmed via CTand treated surgically. The patient recovered completely.Conclusion: One should consider the possibility of subduralhematoma in patients when postdural puncture headache isprolonged or has a change in the character of headache withor without neurological symptoms for an early successfulintervention.

Clival SubduralHematoma after Drainage of Concomitant Intracranial and Spinal Cord Subdural Hematomas ­ Rare Case Report

Concomitant traumatic spinal cord and intracranial subdural hematomas associated with a retroclival hematoma are very uncommon. Their pathophysiology is not totally elucidated, but one hypothesis is the migration of the hematoma from the head to the spine. In the present case report, the authors describe the case of a 51-year-old man presenting with headache, nauseas and back pain after a head trauma who presented with intracranial and spinal cord subdural hematomas. Drainage was performed but, 1 week later, a retroclival subdural hematoma was diagnosed. The present paper discusses the pathophysiology, the clinical presentation, as well as the complications of concomitant traumatic spinal cord and intracranial subdural hematomas associated with a retroclival hematoma, and reviews this condition.

Post partum headache: a case series

Postpartum headache is the complaint of head, neck, or shoulder pain occurring during the first 6 weeks following delivery. Among the women who underwent neuraxial aneasthesia Post Dural puncture headache is one of the most common presentations. However, physicians should be aware that post Dural puncture headache is not the only cause of postpartum headache. Authors present a series of four cases that had varied presentation of post partum headache with varied diagnosis, the first case was of subdural haematoma where CT scan revealed an acute on chronic SDH. The second case was diagnosed as meningitis and the CSF for culture sensitivity grew Streptococcus Pneumoniae .In our third case of cortical vein  thrombosis , NCCT followed by MR venogram  revealed left transverse venous sinus thrombosis and our last case in the series was of posterior reversible encephalopathy syndrome where MRI confirmed the findings of typical findings are symmetric edema involving the white matter of the posterior regions of the cerebral hemispheres. The diagnostic dilemma was resolved by neuroimaging because the clinical presentation was not making us reach a satisfactory diagnosis of the cause of headache. Early resort to neuroimaging and multidisciplinary team effort paved way to early diagnosis and appropriate recovery of the patients.
