Body mass index and fatal stroke in young adults: A national study.

Rates of stroke and obesity have increased in recent years. This study aimed to determine the body mass index (BMI) of fatal stroke cases amongst young adults, their clinical characteristics and the association with BMI with risk factors. All cases aged 15-44 years where death was attributed to stroke for whom BMI was available were retrieved from the National Coronial Information System (1/1/2009-31/12/2016). 179 cases were identified: haemorrhagic (165), ischaemic (5), thrombotic (6), mycotic (3), embolic (0). Proportions in each BMI category were: underweight (5.6%), normal weight (37.4%), overweight (27.4%), obese (29.6%). There was a significant linear trend in the proportion of subarachnoid haemorrhages as BMI increased (p < 0.05), and between higher BMI and hypertension (p < 0.001). There were no group differences in cardiomegaly or left ventricular hypertrophy where known causes were other than hypertension, cardiomyopathy, severe coronary artery atherosclerosis, endocarditis or cerebral arteries atherosclerosis. A history of alcoholism (p < 0.01) was less likely with higher BMI. There was no association between BMI and previous stroke, diabetes, vasculitis, gravid/post-partum, tobacco use, psychostimulant use or injecting drug use. Overweight and obese cases were prominent among young fatalities of stroke. Reducing rates of obesity, and associated hypertension, would be expected to reduce the escalating stoke rates among young adults.

Palliative approach in acute neurological events: a five-year study

SUMMARY INTRODUCTION Acute neurological illness often results in severe disability. Five-year life expectancy is around 40%; half the survivors become completely dependent on outside help. OBJECTIVE Evaluate the symptoms of patients admitted to a Hospital ward with a diagnosis of stroke, subarachnoid hemorrhage or subdural hematoma, and analyze the role of an In-Hospital Palliative Care Support Team. MATERIAL AND METHODS Retrospective, observational study with a sample consisting of all patients admitted with acute neurological illness and with a guidance request made to the In-Hospital Palliative Care Support Team of a tertiary Hospital, over 5 years (2012-2016). RESULTS A total of 66 patients were evaluated, with an age median of 83 years old. Amongst them, there were 41 ischaemic strokes, 12 intracranial bleedings, 12 subdural hematomas, and 5 subarachnoid hemorrhages. The median of delay between admission and guidance request was 14 days. On the first evaluation by the team, the GCS score median was 6/15 and the Palliative Performance Scale (PPS) median 10%. Dysphagia (96.8%) and bronchorrhea (48.4%) were the most prevalent symptoms. A total of 56 patients had a feeding tube (84.8%), 33 had vital sign monitoring (50.0%), 24 were hypocoagulated (36.3%), 25 lacked opioid or anti-muscarinic therapy for symptom control (37,9%); 6 patients retained orotracheal intubation, which was removed. In-hospital mortality was 72.7% (n=48). DISCUSSION AND CONCLUSION Patients were severely debilitated, in many cases futile interventions persisted, yet several were under-medicated for symptom control. The delay between admission and collaboration request was high. Due to the high morbidity associated with acute neurological illness, palliative care should always be timely provided.

RESUMO INTRODUÇÃO Eventos neurológicos agudos resultam frequentemente em incapacidade grave que impede o doente de participar ativamente nas decisões do seu próprio tratamento. A sobrevida a cinco anos ronda os 40%; metade dos sobreviventes fica dependente de terceiros. Objetivo Avaliar a sintomatologia de doentes internados com acidente vascular cerebral (AVC), hemorragia subarcnoideia (HSA) ou subdural (HSD) e analisar a intervenção de uma Equipe Intra-Hospitalar de Suporte em Cuidados Paliativos (EIHSCP). MATERIAL E MÉTODOS Estudo retrospetivo observacional dos doentes com diagnóstico principal de evento neurológico agudo com pedido de colaboração à EIHSCP, num hospital terciário, durante cinco anos (2012-2016). RESULTADOS Avaliados 66 doentes, com média de idade de 83 anos. Destacam-se 41 AVC isquêmicos, 12 hemorrágicos, 12 HSD e 5 HSA. A média da demora entre internamento e pedido de colaboração à EIHSCP foi de 14 dias. Na primeira observação, a média na escala de coma de Glasgow foi de 6/15 e na Palliative Performance Scale (PPS) foi de 10%. Disfagia (96,8%) e broncorreia (48,4%) foram os sintomas mais frequentes. A maioria dos doentes (56/66) mantinha sonda nasogástrica (84,8%); 33 encontravam-se em monitorização cardiorrespiratória (50,0%); 24 estavam sob hipocoagulação (36,3%); 25 necessitavam de opioide e antimuscarínico que não estavam prescritos (37,9%); seis tinham tubo orotraqueal, que foi retirado. A mortalidade intra-hospitalar foi de 72,7% (n=48). DISCUSSÃO E CONCLUSÃO Destaca-se o estado debilitado dos doentes; em muitos casos, intervenções fúteis persistiam, mas várias foram submedicadas para o controle dos sintomas. Verificou-se um tempo de espera elevado até o pedido de colaboração. Pela elevada morbilidade associada a esses eventos, cuidados paliativos diferenciados deveriam ser oferecidos no tempo adequado.

A propensity score analysis of the impact of surgical intervention on unexpected 30-day readmission following admission for subdural hematoma.

OBJECTIVE: Subdural hematoma (SDH) is a common disease that is increasingly being managed nonoperatively. The all-cause readmission rate for SDH has not previously been described. This study seeks to describe the incidence of unexpected 30-day readmission in a cohort of patients admitted to an academic neurosurgical center. Additionally, the relationship between operative management, clinical outcome, and unexpected readmission is explored. METHODS: This is an observational study of 200 consecutive adult patients with SDH admitted to the neurosurgical ICU of an academic medical center. Demographic information, clinical characteristics, and treatment strategies were compared between readmitted and nonreadmitted patients. Multivariable logistic regression, weighted by the inverse probability of receiving surgery using propensity scores, was used to evaluate the association between operative management and unexpected readmission. RESULTS: Of 200 total patients, 18 (9%) died during hospitalization and were not included in the analysis. Overall, 48 patients (26%) were unexpectedly readmitted within 30 days. Sixteen patients (33.3%) underwent SDH evacuation during their readmission. Factors significantly associated with unexpected readmission were nonoperative management (72.9% vs 54.5%, p = 0.03) and female sex (50.0% vs 32.1%, p = 0.03). In logistic regression analysis weighted by the inverse probability of treatment and including likely confounders, surgical management was not associated with likelihood of a good outcome at hospital discharge, but was associated with significantly reduced odds of unexpected readmission (OR 0.19, 95% CI 0.08-0.49). CONCLUSIONS: Over 25% of SDH patients admitted to an academic neurosurgical ICU were unexpectedly readmitted within 30 days. Nonoperative management does not affect outcome at hospital discharge but is significantly associated with readmission, even when accounting for the probability of treatment by propensity score weighted logistic regression. Additional research is needed to validate these results and to further characterize the impact of nonoperative management on long-term costs and clinical outcomes.

Subdural hematomas in 1846 patients with shunted idiopathic normal pressure hydrocephalus: treatment and long-term survival.

OBJECTIVE Subdural hematoma (SDH) is the most common serious adverse event in patients with shunts. Adjustable shunts are used with increasing frequency and make it possible to noninvasively treat postoperative SDH. The objective of this study was to describe the prevalence and treatment preferences of SDHs, based on fixed or adjustable shunt valves, in a national cohort of patients with shunted idiopathic normal pressure hydrocephalus (iNPH), as well as to evaluate the effect of SDH and treatment on long-term survival. METHODS Patients with iNPH who received a CSF shunt in Sweden from 2004 to 2015 were included in a prospective quality registry (n = 1846) and followed regarding SDH, its treatment, and mortality. The treatment of SDH was categorized into surgery, opening pressure adjustments, or no treatment. RESULTS During the study period, the proportion of adjustable shunts increased from 75% to 95%. Ten percent (n = 184) of the patients developed an SDH. In 103 patients, treatment was solely opening pressure adjustment. Surgical treatment was used in 66 cases (36%), and 15 (8%) received no treatment. In patients with fixed shunt valves, 90% (n = 17) of SDHs were treated surgically compared with 30% (n = 49) in patients with adjustable shunts (p < 0.001). There was no difference in long-term patient survival between the SDH and non-SDH groups or between different treatments. CONCLUSIONS SDH remains a common complication after shunt surgery, but adjustable shunts reduced the need for surgical interventions. SDH and treatment did not significantly affect survival in this patient group, thus the noninvasive treatment offered by adjustable shunts considerably reduces the level of severity for this common adverse event.

Decompressive Craniectomy (DC) - Comparative Study of 30-Day Mortality in Surgeries of Severe Brain Trauma with Subdural Hematoma, with and without DC

Objective Compare 30 days mortality of patients harboring acute subdural hematomas in two series, one treated only by wide aspiration of hematoma and other with aspiration followed by decompressive craniectomy. Methods Comparing retrospectively two series of ASD with and without DC. Involved 81 TBI patients with acute subdural hematoma and GCS 8 (Jan 2000 to Nov 2014) arranged into two groups. Group 1 - 58 cases underwent to DC. Group 2 - 23 patients underwent only hematoma aspiration. Results Group 1 showed 44.8% mortality directly due to brain lesion within 30 days. The most frequent associated lesion were contusion in 37.2%. Group 2 the mortality within 30 days was 47.8%. The majority of deaths (82%) resulted from uncontrollable brain swelling, midline shift was present in 94.7% of patients. Conclusion High admission GCS and age less than 50 remain better outcome predictor in 30 days survival for patients undergoing surgery of traumatic ASDH.

Traumatic subdural hematoma: Is there a weekend effect?

OBJECTIVE: Traumatic subdural hematoma (TSDH) is a surgical emergency. The effect of weekend admission on surgery and in-hospital outcomes in TSDH is not known. METHODS: We queried the Nationwide Inpatient Sample from 2002 to 2011 and used ICD-9-CM codes to identify all non-elective admissions with a primary diagnosis of TSDH. We did a subgroup analysis of patients who underwent surgical evacuation. Predictor variables included several patient and hospital characteristics. Outcome variables included length of stay, total hospitalization cost, in-hospital complications, adverse discharge disposition, and in-hospital mortality. We used multivariable analysis to determine if weekend admission was independently associated with increased likelihood of poor outcomes. RESULTS: Out of a total of 404,212 TSDH admissions, 24.8% received surgical intervention. Patients admitted on weekends were less likely to undergo surgical intervention (odds ratio [OR]: 0.85). In the surgical cohort, weekend admissions consisted of more patients with prolonged loss of consciousness (24+h) without return to baseline (7.0% vs. 4.8%). In all TSDH patients and in sub-group of surgical cohort, weekend admission was associated with an increased likelihood of in-hospital complication (OR: 1.06 and 1.12), prolonged length of stay (OR: 1.08 and 1.17), increased total hospital costs (OR: 1.04 and 1.11), adverse discharge (OR: 1.08 and 1.18), and in-hospital mortality (OR: 1.04 and 1.11). All p-values were less than 0.01. CONCLUSION: Our study demonstrates that patients admitted on weekends had similar mortality despite higher severity with no clinically significant weekend effect for tSDH.

Subdural hematoma - a cause of death in the development of a prostatic adenocarcinoma with dural metastases: case report.

Non-traumatic subdural hematoma secondary to dural metastases is a rare complication. Dural metastases from a prostate adenocarcinoma occur in the advanced stages of this pathology and may sometimes be the first manifestation of a prostate carcinoma. Less than 40 cases of subdural hematoma are reported in the literature as a consequence of dural metastases from a prostate adenocarcinoma. The authors present the case of a male patient diagnosed with stage IV prostate adenocarcinoma with bone metastasis, who is admitted for left hemisphere subdural hematoma with right hemiparesis. The evolution of the patient is unfavorable, and the autopsy shows dural metastases and a collection of subdural coagulated blood. The chronic subdural hematoma with re-bleeding is a rare cause of death in the development of a prostate adenocarcinoma.

Traumatic Acute Subdural Hematomas: Analysis of Outcomes and Predictive Factors at a Single Center.

AIM: In the present study, we evaluated the association of the Glasgow Coma Scale (GCS) score and amount of blood loss with mortality in patients presenting with traumatic acute subdural hematoma (ASDH). MATERIAL AND METHODS: This retrospective study was performed on 99 patients who were operated for traumatic acute subdural hematoma (ASDH) without any systemic association at a single center. Epidural hematoma was reported to be the most common additional pathology. Age, sex, mechanism of trauma, time interval between onset of trauma and admission to the emergency ward, associated problems, thickness of hematoma and Glasgow Coma Scale (GCS) score at the time of admission and on discharge were all studied. RESULTS: The GCS score was inversely proportional to the thickness of hematoma and interval between onset of trauma and surgery (p < 0.05). Although the mortality rate was reported to be high in traffic accidents, the rate was low in patients with head trauma only (p < 0.05). The mortality rate was high in patients with associated pathologies (p < 0.05). Lost patients were reported to be older patients with more extensive ASDH or those who presented earlier with a low GCS (p < 0.05). CONCLUSION: ASDH is associated with high mortality. GCS score and the thickness of the ASDH are important predictors of mortality. Age, additional trauma, and interval between trauma and hospital admission are major predictive factors for mortality.

Predictors of Functional Outcome After Subdural Hematoma: A Prospective Study.

BACKGROUND: Although the incidence of subdural hematoma (SDH) has increased in the US in the last decade, limited prospective data exist examining risk factors for poor outcome. METHODS: A prospective, observational study of consecutive SDH patients was conducted from 7/2008 to 11/2011. Baseline clinical data, hospital and surgical course, complications, and imaging data were compared between those with good versus poor 3-month outcomes (modified Rankin Scores [mRS] 0-3 vs. 4-6). A multivariable logistic regression model was constructed to identify independent predictors of poor outcome. RESULTS: 116 SDH patients (18 acute, 56 mixed acute/subacute/chronic, 42 subacute/chronic) were included. At 3 months, 61 (53 %) patients had good outcomes (mRS 0-3) while 55 (47 %) were severely disabled or dead (mRS 4-6). Of those who underwent surgical evacuation, 54/94 (57 %) had good outcomes compared to 7/22 (32 %) who did not (p = 0.030). Patients with mixed acuity or subacute/chronic SDH had significantly better 3-month mRS with surgery (median mRS 1 versus 5 without surgery, p = 0.002) compared to those with only acute SDH (p = 0.494). In multivariable analysis, premorbid mRS, age, admission Glasgow Coma Score, history of smoking, and fever were independent predictors of poor 3-month outcome (all p < 0.05; area under the curve 0.90), while SDH evacuation tended to improve outcomes (adjusted OR 3.90, 95 % CI 0.96-18.9, p = 0.057). CONCLUSIONS: Nearly 50 % of SDH patients were dead or moderate-severely disabled at 3 months. Older age, poor baseline, poor admission neurological status, history of smoking, and fever during hospitalization predicted poor outcomes, while surgical evacuation was associated with improved outcomes among those with mixed acuity or chronic/subacute SDH.

Head computed tomographic measurement as a predictor of outcome in patients with subdural hematoma with cerebral edema.

BACKGROUND: The ability to predict outcome in patients with cerebral edema is important because it can influence treatment strategy. We evaluated whether differences in head computed tomographic (CT) measurements in Hounsfield units (HU) of white matter and gray matter can be used as a predictor of outcome in patients with subdural hematoma with cerebral edema. METHODS: We evaluated 34 patients who had subdural hematoma with cerebral edema following acute closed head trauma and had undergone head CT within a few hours of admission. We divided them into the survival (n = 24) group and death (n = 10) group, and measured the HU of white matter and gray matter at injury and non-injury sites. RESULTS: There were no significant differences in operation time or blood loss during surgery between the two groups. Only the HU of white matter in the injury site of patients in the death group were decreased significantly. A cut-off value of 31.5 for HU of white matter showed 80.0 % sensitivity and 99.9 % specificity for death; the area under the curve was 0.91. DISCUSSION: Our results are more evidence of the support of neurogenic edema in trauma rather than an important clinical tool at this stage. However, HU values in WM may be one factor in the decision-making process that affects patient outcome. Changing the treatment strategy in patients with a low HU value in the WM at the injury site may bring about an improvement in patient outcome. CONCLUSION: Measurement in HU of white matter at the injury site might be useful as a predictor of outcome in patients with subdural hematoma with cerebral edema.

Patient factors associated with 30-day morbidity, mortality, and length of stay after surgery for subdural hematoma: a study of the American College of Surgeons National Surgical Quality Improvement Program.

OBJECTIVE: Surgery for subdural hematoma (SDH) is a commonly performed neurosurgical procedure. This study identifies patient characteristics associated with adverse outcomes and prolonged length of stay (LOS) in patients who underwent surgical treatment for SDH. METHODS: All patients in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) who were treated via craniotomy or craniectomy for SDH between 2005 and 2012 were identified. Patient demographics, comorbidities, and 30-day outcomes were described. Multivariate regression was used to identify predictors of adverse events. RESULTS: A total of 746 surgical procedures performed for SDH were identified and analyzed. Patients undergoing this procedure were 64% male with an average age (± SD) of 70.9 ± 14.1 years. The most common individual adverse events were death (17%) and intubation for more than 48 hours (19%). In total, 34% experienced a serious adverse event other than death, 8% of patients returned to the operating room (OR), and the average hospital LOS was 9.8 ± 9.9 days. In multivariate analysis, reduced mortality was associated with age less than 60 years (relative risk [RR] = 0.47, p = 0.017). Increased mortality was associated with gangrene (RR = 3.5, p = 0.044), ascites (RR = 3.00, p = 0.006), American Society of Anesthesiologists (ASA) Class 4 or higher (RR = 2.34, p = 0.002), coma (RR = 2.25, p < 0.001), and bleeding disorders (RR = 1.87, p = 0.003). Return to the OR was associated with pneumonia (RR = 3.86, p = 0.044), male sex (RR = 1.85, p = 0.015), and delirium (RR = 1.75, p = 0.016). Serious adverse events were associated with ventilator dependence preoperatively (RR = 1.86, p < 0.001), dialysis (RR = 1.44, p = 0.028), delirium (RR = 1.40, p = 0.005), ASA Class 4 or higher (RR = 1.36, p = 0.035), and male sex (RR = 1.29, p = 0.037). Similarly, LOS was increased in ventilator dependent patients by 1.56-fold (p = 0.002), in patients with ASA Class 4 or higher by 1.30-fold (p = 0.006), and in delirious patients by 1.29-fold (p = 0.008). CONCLUSIONS: Adverse outcomes are common after surgery for SDH. In this study, 18% of the patients died within 30 days of surgery. Factors associated with adverse outcomes were identified. Patients and families should be counseled about the serious risks of morbidity and death associated with acute traumatic SDH requiring surgery.

Subdural Hematoma and Oral Anticoagulation: A Therapeutic Dilemma from the Neurosurgical Point of View.

BACKGROUND: Oral anticoagulation is a common prophylactic therapy for several diseases with a high thromboembolic risk. Such medication harbors a possible hemorrhage risk, with a special risk for subdural hematoma (SDH). The safety and efficacy of resumption of oral anticoagulation versus long-term discontinuation has not been fully clarified in patients who experienced SDH while under treatment with oral anticoagulation. MATERIAL AND METHODS: We investigated the outcome of 49 patients who were identified retrospectively to have a SDH while receiving oral anticoagulation. RESULTS: Most bleeding occurred while patients were within the recommended therapeutic window for oral anticoagulation. Mortality was 15%. The event-free survival probability was higher in the group of patients with reinstitution of phenprocoumon therapy than in the group without. Over a median follow-up of 32 months, thromboembolic events occurred in 4 of 23 patients without oral anticoagulation versus in none of 15 patients with phenprocoumon; hemorrhagic complications occurred in 1 in 23 versus 3 in 15 patients. CONCLUSIONS: Reinstitution of oral anticoagulation with phenprocoumon after previous SDH appears to have an acceptable risk for hemorrhagic complications. Decision making might consider case-by-case differences. To establish specific guidelines, prospective large cohort studies are needed.

Adverse Outcomes After Initial Non-surgical Management of Subdural Hematoma: A Population-Based Study.

BACKGROUND: Little is known about the natural history of non-surgically managed subdural hematoma (SDH). The purpose of this study is to determine rates of adverse events after non-surgical management of SDH and whether these outcomes differ depending on traumatic versus nontraumatic etiology. A retrospective cohort study was conducted using administrative claims data on all emergency department visits and acute care hospitalizations at nonfederal facilities in California from 2005 to 2011, Florida from 2005 to 2012, and New York from 2006 to 2011. We included patients who were discharged home after hospitalization with a first-recorded diagnosis of SDH and no record of surgical hematoma evacuation. METHODS: Patients were followed for readmission with SDH, readmission for surgical SDH evacuation, and fatal readmission with SDH. Survival statistics and the log-rank test were used to compare rates of these adverse events after traumatic versus nontraumatic SDH. Multivariable Cox regression analysis was used to compare hazards for traumatic versus nontraumatic etiology while adjusting for age, sex, race, insurance status, presence of dementia, alcohol use, acquired abnormalities in coagulation, acquired abnormalities in platelet function, hypertension, atrial fibrillation, venous thromboembolism, ischemic stroke, coronary heart disease, and valvular disease. RESULTS: We identified 27,502 conservatively treated patients with SDH, of which 70.9% were traumatic and 29.1% nontraumatic. Compared to patients with traumatic SDH, patients with nontraumatic SDH had significantly higher rates of subsequent hospitalization with SDH (cumulative 90-day rates: 15.3 % [95% CI 14.5-16.1%] vs. 10.3% [95% CI 9.9-10.8%]), surgical SDH evacuation (7.8% [95% CI 7.3-8.5%] vs. 5.5% [95% CI 5.2-5.8%]), and SDH-related in-hospital death (1.0% [95% CI 0.8-1.2%] vs. 0.4% [95 % CI 0.3-0.5%]). In multivariable Cox regression analysis, nontraumatic etiology was associated with a higher hazard of readmission with SDH (HR 1.4; 95% CI 1.3-1.5), surgery (HR 1.3; 95% CI 1.2-1.4), and in-hospital mortality (HR 1.9; 95% CI 1.4-2.5). Our findings were unchanged in sensitivity analyses that also adjusted for Elixhauser comorbidities. CONCLUSIONS: Approximately one in eight patients with a conservatively managed SDH was readmitted with SDH within 90 days. A substantial proportion of these readmissions involved surgical hematoma evacuation. These outcomes occurred significantly more often after nontraumatic as compared to traumatic SDH.

The Effect of ß-blockade on Survival After Isolated Severe Traumatic Brain Injury.

BACKGROUND: Several North American studies have observed survival benefit in patients exposed to ß-blockers following traumatic brain injury (TBI). The purpose of this study was to evaluate the effect of ß-blockade on mortality in a Swedish cohort of isolated severe TBI patients. METHODS: The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between 1/2007 and 12/2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS)≥3 excluding extra-cranial injuries AIS≥3. Multivariable logistic regression analysis was used to determine the effect of ß-blocker exposure on mortality. Also, a subgroup analysis was performed to investigate the risk of mortality in patients on pre-admission ß-blocker versus not and the effect of specific type of ß-blocker on the overall outcome. RESULTS: Overall, 874 patients met the study criteria. Of these, 33% (n=287) were exposed to ß-blockers during their hospital admission. The exposed patients were older (62±16 years vs. 49±21 years, p<0.001), and more severely injured based on their admission GCS, ISS, and head AIS scores (GCS≤8: 32% vs. 28%, p=0.007; ISS≥16: 71% vs. 59%, p=0.001; head AIS≥4: 60% vs. 45%, p<0.001). The crude mortality was higher in patients who did not receive ß-blockers (17% vs. 11%, p=0.007) during their admission. After adjustment for significant confounders, the patients not exposed to ß-blockers had a 5-fold increased risk of in-hospital mortality (AOR 5.0, CI 95% 2.7-8.5, p=0.001). No difference in survival was noted in regards to the type of ß-blocker used. Subgroup analysis revealed a higher risk of mortality in patients naive to ß-blockers compared to those on pre-admission ß-blocker therapy (AOR 3.0 CI 95% 1.2-7.1, p=0.015). CONCLUSIONS: ß-blocker exposure after isolated severe traumatic brain injury is associated with significantly improved survival. We also noted decreased mortality in patients on pre-admission ß-blocker therapy compared to patients naive to such treatment. Further prospective studies are warranted.

Aggressive operative treatment of isolated blunt traumatic brain injury in the elderly is associated with favourable outcome.

Outcome after traumatic brain injury (TBI) in the elderly has not been fully elucidated. The present retrospective observational study investigates the age-dependent outcome of patients suffering from severe isolated TBI with regard to operative and non-operative treatment. Data were prospectively collected in the TraumaRegister DGU. Anonymous datasets of 8629 patients with isolated severe blunt TBI (AISHead≥3, AISBody≤1) documented from 2002 to 2011 were analysed. Patients were grouped according to age: 1-17, 18-59, 60-69, 70-79 and ≥80 years. Cranial fractures (44.8%) and subdural haematomas (42.6%) were the most common TBIs. Independent from the type of TBI the group of patients with operative treatment declined with rising age. Subgroup analysis of patients with critical TBI (AISHead=5) revealed standardised mortality ratios (SMRs) of 0.81 (95% CI 0.75-0.87) in case of operative treatment (n=1201) and 1.13 (95% CI 1.09-1.18) in case of non-operative treatment (n=1096). All age groups ≥60 years showed significantly reduced SMRs in case of operative treatment. Across all age groups the group of patients with low/moderate disability according to the GOS (4 or 5 points) was higher in case of operative treatment. Results of this retrospective observational study have to be interpreted cautiously. However, good outcome after TBI with severe space-occupying haemorrhage is more frequent in patients with operative treatment across all age groups. Age alone should not be the reason for limited care or denial of operative intervention.

Time interval to surgery and outcomes following the surgical treatment of acute traumatic subdural hematoma.

Although the pre-surgical management of patients with acute traumatic subdural hematoma prioritizes rapid transport to the operating room, there is conflicting evidence regarding the importance of time interval from injury to surgery with regards to outcomes. We sought to determine the association of surgical timing with outcomes for subdural hematoma. A retrospective review was performed of 522 consecutive patients admitted to a single center from 2006-2012 who underwent emergent craniectomy for acute subdural hematoma. After excluding patients with unknown time of injury, penetrating trauma, concurrent cerebrovascular injury, epidural hematoma, or intraparenchymal hemorrhage greater than 30 mL, there remained 45 patients identified for analysis. Using a multiple regression model, we examined the effect of surgical timing, in addition to other variables on in-hospital mortality (primary outcome), as well as the need for tracheostomy or gastrostomy (secondary outcome). We found that increasing injury severity score (odds ratio [OR] 1.146; 95% confidence interval [CI] 1.035-1.270; p=0.009) and age (OR1.066; 95%CI 1.006-1.129; p=0.031) were associated with in-hospital mortality in multivariate analysis. In this model, increasing time to surgery was not associated with mortality, and in fact had a significant effect in decreasing mortality (OR 0.984; 95%CI 0.971-0.997; p=0.018). Premorbid aspirin use was associated with a paradoxical decrease in mortality (OR 0.019; 95%CI 0.001-0.392; p=0.010). In this patient sample, shorter time interval from injury to surgery was not associated with better outcomes. While there are potential confounding factors, these findings support the evaluation of rigorous preoperative resuscitation as a priority in future study.

Traumatic subarachnoid hemorrhage due to motor vehicle crash versus fall from height: a 4-year epidemiologic study.

BACKGROUND: Traumatic brain injury (TBI) is a common cause of morbidity and mortality worldwide. It is difficult to estimate the real incidence of traumatic subarachnoid hemorrhage (TSAH). Although TSAH after trauma is associated with poor prognoses, the impact of mechanism of injury (MOI) and the pathophysiology remains unknown. We hypothesized that outcome of TSAH caused by motor vehicle crash (MVC) or fall from height (FFH) varies based on the MOI. METHODS: Data were collected retrospectively from a prospectively created database registry in the section of Trauma Surgery at Hamad General Hospital between January 2008 and July 2012. All patients presented with head trauma and TSAH were included. Patient data included age, gender, nationality, mechanism of injury, injury severity score (ISS), types of head injuries, and associated injuries. Ventilator days, intensive care unit length of stay, pneumonia, and mortality were also studied. RESULTS: A total of 1665 patients with TBI were identified, of them 403 had TSAH with a mean age of 35 ± 15 years. Of them 93% were male patients and 86% were expatriates. MVC (53%) and FFH (35%) were the major mechanisms of injury. The overall mean ISS and head abbreviated injury score were 19 ± 10.6 and 3.4 ± 0.96, respectively. Patients in MVC group sustained severe TSAH, had significantly greater head abbreviated injury score (3.5 ± 0.9 vs. 3.2 ± 0.9; P = 0.009) and ISS (21.6 ± 10.6 vs. 15.9 ± 9.5; P = 0.001), and lower scene Glasgow coma scale (10.8 ± 4.8 vs. 13.2 ± 3.4; P = 0.001) compared with the FFH group. In addition, the MVC group sustained more intraventricular hemorrhage (4.7 vs. 0.7; P = 0.001) and diffuse axonal injury (4.2 vs. 2.9; P = 0.001). In contrast, extradural hemorrhage (14.3% vs. 11.6%; P = 0.008) was higher in the FFH group. Lower extremities (14% vs. 4.3%; P = 0.004) injury was mainly associated with the MVC group. The overall mortality was 19 % among patients with TSAH. The mortality rate was higher in the MVC group when compared with the FFH group (24% vs. 10%; P = 0.001). In both groups, ISS and Glasgow coma scale at the scene were independent predictors of mortality. CONCLUSIONS: Patients with TSAH have a higher mortality rate. In this population, MVCs are associated with a 3-fold increased risk of mortality. Therefore, prevention of MVC and fall can reduce the incidence and severity of TBI in Qatar.

No todo es diversión: papiledema y montana rusa / Not everything is fun: papilledema and roller coaster

Presentamos el caso de una paciente de 30 años de edad previamente saludable, quien desarrolló luego de numerosos viajes en una montaña rusa un hematoma subdural espontáneo y un higroma contralateral. La estroma velocidad y despliegue de fuerza G, la sucesión de momentos de aceleración y desaceleración, los bruscos movimientos cefálicos con tironeo lateral del cerebro y el número de veces que permitió el viaje, constituyeron un riesgo significativo de ruptura de venas puente, siendo posible que las reiteradas caídas de una boya remolcada hayan constituido el último trauma y desencadenamiento final

We present the case of a 30-year-old previously healthy patient, who developed ofter numerous trips on a roller coaster a spontaneous hematoma subdural and a contralateral hygroma. Extreme speed and G-force deployment, the succession of moments of acceleration and deceleration, sudden cephalic movements with snarling side of the brain and the number of times that he repeated the trip, they constituted a significant risk of rupture of veins bridge, being possible that repeated falls from a towed buoy have produced the latest trauma and final trigger

Outcomes in octogenarians with subdural hematomas.

OBJECTIVE: In the majority of literature concerning age in TBI, specifically in subdural hematomas (SDH), the mean age of patients considered elderly is 55-65. Limited data in SDH patients>75 years suggest an increased mortality rate. The impact of medical decision making on these data is not well-documented. PATIENTS/METHODS: We use the Nationwide Inpatient Sample (NIS) database to compare outcomes between SDH patients 60-79 and ≥80. As administrative databases have some shortcomings, i.e. in-hospital data only, acute and chronic SDHs listed together, we examined institutional data to evaluate the impact of these factors on medical decision making which may falsely elevate mortality rates. RESULTS: In-hospital mortality was increased in NIS patients>80 treated both surgically and non-surgically (P<0.05). Our institutional data confirmed higher in-hospital mortality rates in patients>80 with SDHs as a group. However, the SDH patients>80 who underwent surgery at our institution had much lower mortality rates. We found that patients≥80 made up 87% of all patients with "surgical lesions" that were not operated on. Type of subdural, admission GCS, and baseline cognitive status appeared to have a significant impact on surgical decision making. CONCLUSION: This study examines mortality rates in patients>80 with SDHs who are managed surgically and non-surgically using a large administrative database and institutional data. It provides preliminary insight into medical decision making which make affect mortality rates of the very elderly.
