Abstract
Recently, Oslo grading system (OGS) for prediction of recurrence in chronic subdural hematoma (cSDH) was introduced. The aim of the study was to validate and if applicable to modify the grading system. Data of all patients admitted to the Goethe University Hospital between 2016 and 2018 with chronic subdural hematoma were prospectively entered into a database. Dataset of patients with uni- (n = 272) and bilateral cSDH (n = 177) were used for the validation of OGS via logistic regression analysis. Additional predictors were identified and integrated to build a modified OGS (mOGS). Internal validation of the modified OGS was performed using same dataset of patients. The OGS showed a significant good predictive value with correlating increase of recurrence rate depending on the level of score in unilateral cSDH (p = 0.002). Regarding bilateral cSDH, there was no significant predictive value found (p = 0.921). By performing uni- and multivariate analysis, additional predictors for recurrence in uni- and bilateral cSDH were identified and integrated into the score system. Accordingly, the mOGS for unilateral cSDH inherited 4 components: previous OGS with 3 components (OR1.6) and seizure (OR2.5) (0 point, 0% recurrence rate; 1-2 points, 17.4%; 3-4 points, 30.6%; ≥ 5 points, 80%). Regarding bilateral cSDH, the mOGS consisted of 4 components as well: hypodense/gradation subtypes (OR3.3), postoperative unilateral volume > 80 mL (OR7.4), postoperative unilateral air trapping > 80 mL (OR15.3), and seizure (OR5.5) (0 point, 3.6% recurrence rate; 1 point, 30.6%; 2 points, 53.5%; 3 points, 58.3%; ≥ 4 points, 100%). Furthermore, the mOGS was internally verified showing high significant predictive power for recurrent hematoma in uni- (p = 0.004) and bilateral cSDH (p < 0.001). External validation of OGS showed accurate risk stratification of recurrence in unilateral cSDH; however, the validation failed for bilateral cSDH. Thus, mOGS was developed to strengthen its clinical utility and applicability.

Abstract
Chronic subdural hematomas (CSDHs) frequently affect the elderly population. The postoperative recurrence rate of CSDHs is high, ranging from 3% to 20%. Both qualitative and quantitative analyses have been explored to investigate the mechanisms underlying postoperative recurrence. We surveyed the pathophysiology of CSDHs and analyzed the relative factors influencing postoperative recurrence. Here, we summarize various qualitative methods documented in the literature and present our unique computer-assisted quantitative method, published previously, to assess postoperative recurrence. Imaging features of CSDHs, based on qualitative analysis related to postoperative high recurrence rate, such as abundant vascularity, neomembrane formation, and patent subdural space, could be clearly observed using the proposed quantitative analysis methods in terms of mean hematoma density, brain re-expansion rate, hematoma volume, average distance of subdural space, and brain shifting. Finally, artificial intelligence (AI) device types and applications in current health care are briefly outlined. We conclude that the potential applications of AI techniques can be integrated to the proposed quantitative analysis method to accomplish speedy execution and accurate prediction for postoperative outcomes in the management of CSDHs.

Abstract
Background Chronic subdural hematoma (CSDH) is one of the most frequent reason for cranial neurosurgical consultation. There is no widely accepted medical treatment for this condition. Herein, we present the protocol for the Tranexamic Acid (TXA) in Chronic Subdural Hematomas (TRACS) trial aiming at determining whether TXA can increase the rate of CSDH resolution following conservative management, lower the number of required surgical procedures and decrease the rate of CSDH recurrence following surgical evacuation. Methods TRACS is a multicenter, double-blind, randomized, parallel-design, placebo-controlled, phase IIB study designed to provide preliminary efficacy data as well as feasibility, safety and incidence data required to plan a larger definitive phase III trial. Consecutive patients presenting with a diagnosis of chronic subdural hematoma will be screened for eligibility. Exclusion criteria include: specific risk factors for thromboembolic disease, anticoagulant use or contraindication to TXA. A total of 130 patients will be randomized to receive either 750 mg of TXA daily or placebo until complete radiological resolution of the CSDH or for a maximum of 20 weeks. CSDH volume will be measured on serial computed tomography (CT) scanning. Cognitive function tests, quality of life questionnaires as well as functional autonomy assessments will be performed at enrollment, at 10 weeks following randomization and at 3 months following treatment cessation. During the treatment period, patients will undergo standard CSDH management with surgery being performed at the discretion of the treating physician. If surgery is performed, the CSDH and its outer membrane will be sampled for in vitro analysis. The primary outcome is the rate of CSDH resolution by 20 weeks without intervening unplanned surgical procedure. Secondary outcomes include: CSDH volume, incidence of surgical evacuation procedures, CSDH recurrence, cognitive functions, functional autonomy, quality of life, incidence of complications and length of hospital stay. Planned subgroup analyses will be performed for conservatively versus surgically managed subjects and highly versus poorly vascularized CSDH. Discussion CSDH is a frequent morbidity for which an effective medical treatment has yet to be discovered. The TRACS trial will be the first prospective study of TXA for CSDH. Trial registration NCT ID: NCT02568124.

Abstract
Objective Magnetic resonance imaging (MRI) of chronic subdural hematoma (CSDH) detects various patterns, which can be attributed to many factors. The purpose of this study was to measure the level of interleukin-6 (IL-6), interleukin-8 (IL-8), and highly specific protein [beta-trace protein (βTP)] for cerebrospinal fluid (CSF) in CSDHs, and correlate the levels of these markers with the MRI findings. Methods Thirty one patients, treated surgically for CSDH, were divided on the basis of MRI findings into hyperintense and non-hyperintense groups. The concentrations of IL-6, IL-8, and βTP in the subdural fluid and serum were measured. The βTP was considered to indicate an admixture of CSF to the subdural fluid if βTP in the subdural fluid (βTPSF)/βTP in the serum (βTPSER)>2. Results The mean concentrations of IL-6 and IL-8 of the hyperintense group (n=17) of T1-WI MRI were 3975.1±1040.8 pg/mL and 6873.2±6365.4 pg/mL, whereas them of the non-hyperintense group (n=14) were 2173.5±1042.1 pg/mL and 2851.2±6267.5 pg/mL (p<0.001 and p=0.004). The mean concentrations of βTPSF and the ratio of βTPSF/βTPSER of the hyperintense group (n=13) of T2-WI MRI were 7.3±2.9 mg/L and 12.6±5.4, whereas them of the non-hyperintense group (n=18) were 4.3±2.3 mg/L and 7.5±3.9 (p=0.011 and p=0.011). Conclusion The hyperintense group on T1-WI MRI of CSDHs exhibited higher concentrations of IL-6 and IL-8 than non-hyperintense group. And, the hyperintese group on T2-WI MRI exhibited higher concentrations of βTPSF and the ratio of βTPSF/βTPSER than non-hyperintense group. These findings appear to be associated with rebleeding and CSF admixture in the CSDHs.

Abstract
We studied the mechanism underlying seizure induction in patients with chronic subdural hematoma. In our study population of 1,009 patients with chronic subdural hematoma, 26 (2.6%) had seizure-related complications. Six of them had already been diagnosed with epilepsy (4 patients) or suspected of having secondary epilepsy (2 patients) after experiencing traffic accidents or cerebral bleeding. Twenty patients (seizure group) had been tentatively diagnosed as having hematoma-induced convulsion. Of the remaining 989 patients without convulsion, 40 randomly sampled patients were included in the non-seizure group by matching with clinical terms. Intergroup comparisons showed that patients with dementia were more common in the seizure group than in the non-seizure group; however, no intergroup differences were observed for other clinical parameters. Radiological examinations showed that bilateral hematomas were relatively more common and sulcal hyperintensity on FLAIR MR images was significantly more frequent in the seizure group than in the non-seizure group. Interestingly, many patients presenting with sulcal hyperintensity exhibited mixed-density hematomas on CT images. These findings suggest the mechanism by which hematoma content infiltrates into the brain parenchyma and the subsequent induction of convulsions by the stimulatory component.

Abstract
Chronic subdural hematoma (CSDH) is a relatively common disorder in neurosurgery on elderly patients, though the mechanism that causes the disease remains unclear. Studies have suggested that local anticoagulation and inflammatory changes may be important in its pathogenesis. Most studies have used a basic bivariate statistical analysis to assess complex immunological responses in patients with this disorder, hence a more sophisticated multivariate statistical approach might be warranted. Our objective was to assess the association and correlation between the pro- and anti-inflammatory responses in a cohort of patients with chronic subdural hematoma (n=57) using an exploratory and confirmatory factor analysis. Thirteen assigned pro-inflammatory (TNF-α, IL-1β, IL-2, IL-2R, IL-6, IL-7, IL-12, IL-15, IL-17, CCL2, CXCL8, CXCL9 and CXCL10) and five assigned anti-inflammatory (IL-1RA, IL-4, IL-5, IL-10 and IL-13) cytokines from blood and hematoma fluid samples were examined. Exploratory factor analysis indicated two major underlying immunological processes expressed by the cytokines in both blood and hematoma fluid, but with a different pattern and particularly regarding the cytokines IL-13, IL-6, IL-4 and TNF-α. Scores from confirmatory factor analysis models exhibited a higher correlation between pro- and anti-inflammatory activities in blood (r=0.98) than in hematoma fluid samples (r=0.92). However, correlations of inflammatory processes between blood and hematoma fluid samples were lower and non-significant. A structural equation model showed a significant association between increased anti-inflammatory activity in hematoma fluid samples and a lower risk of recurrence, but this relationship was not statistically significant in venous blood samples. Moreover, these findings indicate that anti-inflammatory activities in the hematoma may play a role in the risk of a recurrence of CSDH.

Abstract
Inflammation and the coagulation system may influence the genesis of chronic subdural hematoma (CSDH). The appearance of CSDH on computed tomography (CT) varies with the stage of the hematoma. This study investigated the pathogenesis and the recurrence of CSDH by comparing cytokine levels with the CT features of CSDH in 26 patients with 34 CSDHs who underwent single burr-hole surgery at our hospital between October 2004 and November 2006. The hematoma components removed during the procedure were examined, and the hematoma serum levels of cytokines measured such as thrombomodulin (TM), interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), and interleukin-10 (IL-10). Using CT, mixed density hematomas were distinguished from other homogeneous hematomas, and found that the TM level was significantly higher in mixed density hematomas than in homogeneous hematomas (p = 0.043). Mixed density hematomas were classified into three subtypes (laminar, separated, and trabecular hematomas). The TM level was significantly higher in laminar and separated hematomas than in other hematomas (p = 0.01). The levels of IL-6, TNFα, and IL-10 were extremely high, but showed no significant differences in relation to the CT features. Mixed density hematomas had high recurrence rate, as reported previously, and TM level was high in mixed density hematomas such as laminar and separated mixed density hematomas. The present findings suggest that the types of CSDH associated with high TM levels tend to have higher recurrence rate.

Abstract
INTRODUCTION Recurrence of chronic subdural haematoma (CSDH) occurs in up to 30% of patients. The rate of recurrence is higher in bilateral versus unilateral CSDH and the reason for this has not been fully elucidated. There are few quantitative studies of temporal changes in brain re-expansion after haematoma evacuation. The aim of this study is to use a simple volumetric image analysis method to quantify temporal changes of postoperative brain re-expansion in unilateral and bilateral CSDH. METHODS We reviewed computed tomography (CT) scans of 20 consecutive patients (16 men, 4 women; median age, 73.5 years) with CSDH (unilateral, n=10; bilateral, n=10) who underwent surgery (burr hole drainage on one or both sides) at our institutions during the period from June 2006 to August 2008. Haematoma volume was quantified preoperatively and on postoperative days 14 and 30 by computer-based image analysis (PACS Web 1000 System) of CT scans. We then calculated the brain re-expansion rate (BRR) for postoperative days 14 and 30. RESULTS Haematoma volume remained significantly higher (p<0.001) in bilateral versus unilateral CSDHs at both postoperative time points, and the BRR was significantly greater (p<0.001) in unilateral versus bilateral CSDH at both time points. CONCLUSION Results of this quantitative analysis provide definitive evidence for a poor BRR in bilateral compared to unilateral CSDH. This impairment may result in shifting of the brain and shearing of blood vessels, resulting in a higher recurrence rate.

Abstract
Abstract
OBJECTIVE
Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage that is known to recur in up to one-fifth of treated patients. We present a patient with recurrent CSDH who was found to have a defect in the fibrinolytic pathway, which may be a novel explanation for recurrent CSDH. This defect, deficiency of plasminogen activator inhibitor type I (PAI-1), should be recognized as a possible cause of CSDH.
CLINICAL PRESENTATION
A 49-year-old man presented with a CSDH, which recurred each time after 2 initially-effective craniotomies.
INTERVENTION
A deficiency of PAI-1 was diagnosed after the second recurrence. We hypothesize that this defect in the fibrinolytic system contributed to the recurrent hematoma. Treatment with aminocaproic acid led to resolution of the CSDH.
CONCLUSION
PAI-1 deficiency should be considered in patients with recurrent CSDH that lack another compelling explanation, particularly in patients with a family history of bleeding diatheses. PAI-1 deficiency can be identified by measuring plasma levels and can be treated with an oral course of aminocaproic acid.

Abstract
The incidence of seizures in patients undergoing burr-hole crainiostomy with closed-system drainage for chronic subdural hematoma (CSDH) is low. The post-operative use of anticonvulsants is, thus, controversial. In this study, we tried to correlate pre-operative computed tomographic (CT) appearance of the CSDH with the need for post-operative seizure prophylaxis. From April 1998 to November 2001, 128 cases of CSDH surgically treated at our hospital were studied. All patients underwent burr-hole craniostomy with closed system drainage. All CSDHs were classified as low-density, isodense, and mixed-density lesions according to CT findings. The incidence of early post-operative seizures (within 3 weeks of surgery) among all patients was 5.4% (7/128). In the subgroups by lesion density, the incidences were 6.2% (1/16) in the low-density group, 2.4% (2/83) in the isodense group, and 13.7% (4/29) in the mixed-density group (all p < 0.05). The mean age among the seven patients (five males and two females) who had seizures was 71 years. The locations of the CSDHs among the 128 patients were the left side of the brain in 53 (41.4%) patients, right side in 45 (35.2%), and bilateral in 30 (23.4%) patients. Among the seven patients who suffered from post-operative seizures, five (71.4%) had left side CSDHs, one (14.2%) had a right side CSDH, and one (14.2%) had bilateral CSDHs. We concluded that the post-operative seizure rate appeared high in the group with mixed-density type lesions on CT, and in those with left unilateral CSDH. We suggest the use of prophylactic anticonvulsants for patients with mixed-density lesions on pre-operative CT.

Abstract
In the United States, roughly one of every 100 children is subjected to some form of neglect or abuse; inflicted injury is responsible for approximately 1,200 deaths per year. Child physical abuse may manifest as virtually any injury pattern known to medicine. Some of the injuries observed in battered children are relatively unique to this population (especially when observed in infants) and therefore are highly suggestive of nonaccidental, or inflicted, injury. Worrisome injuries include rib fracture, metaphyseal fracture, interhemispheric extraaxial hemorrhage, shear-type brain injury, vertebral compression fracture, and small bowel hematoma and laceration. As noted, however, virtually any injury may be inflicted; therefore, careful consideration of the nature of the injury, the developmental capabilities of the child, and the given history are crucial to determine the likelihood that an injury was inflicted. The majority of these injuries are readily detectable at imaging, and radiologic examination forms the mainstay of evaluation of child physical abuse. Detection of metaphyseal fracture (regarded as the most specific radiographically detectable injury in abuse) depends on high-quality, small field-of-view radiographs. The injury manifests radiographically as a lucent area within the subphyseal metaphysis, extending completely or partially across the metaphysis, roughly perpendicular to the long axis of the bone. Acute rib fractures (which in infants are strongly correlated with abuse) appear as linear lucent areas. They may be difficult to discern when acute; thus, follow-up radiography increases detection of these fractures. For skull injuries, radiography is best for detecting fractures, but computed tomography and magnetic resonance imaging best depict intracranial injury.

Abstract
OBJECTIVE To evaluate the results of surgical treatment options for chronic subdural haematoma in contemporary neurosurgery according to evidence based criteria. METHODS A review based on a Medline search from 1981 to October 2001 using the phrases "subdural haematoma" and "subdural haematoma AND chronic". Articles selected for evaluation had at least 10 patients and less than 10% of patients were lost to follow up. The articles were classified by three classes of evidence according to criteria of the American Academy of Neurology. Strength of recommendation for different treatment options was derived from the resulting degrees of certainty. RESULTS 48 publications were reviewed. There was no article that provided class I evidence. Six articles met criteria for class II evidence and the remainder provided class III evidence. Evaluation of the results showed that twist drill and burr hole craniostomy are safer than craniotomy; burr hole craniostomy and craniotomy are the most effective procedures; and burr hole craniostomy has the best cure to complication ratio (type C recommendation). Irrigation lowers the risk of recurrence in twist drill craniostomy and does not increase the risk of infection (type C recommendation). Drainage reduces the risk of recurrence in burr hole craniostomy, and a frontal position of the drain reduces the risk of recurrence (type B recommendation). Drainage reduces the risk of recurrence in twist drill craniostomy, and the use of a drain does not increase the risk of infection (type C recommendation). Burr hole craniostomy appears to be more effective in treating recurrent haematomas than twist drill craniostomy, and craniotomy should be considered the treatment of last choice for recurrences (type C recommendation). CONCLUSIONS The three principal techniques-twist drill craniostomy, burr hole craniostomy, and craniotomy-used in contemporary neurosurgery for chronic subdural haematoma have different profiles for morbidity, mortality, recurrence rate, and cure rate. Twist drill and burr hole craniostomy can be considered first tier treatment, while craniotomy may be used as second tier treatment. A cumulative summary of data shows that, overall, the postoperative outcome of chronic subdural haematoma has not improved substantially over the past 20 years.
