S100β protein levels as a parameter to assess the clinical development of adult patients with mild traumatic brain injury in Dr. Moewardi Public Hospital, Surakarta

Background: Mild traumatic brain injury (mTBI) is a health problem with an increasing incidence in many developed countries. The standard for examining mTBI is a CT scan, but it is costly, is not always available in all hospitals, and carries a risk of radiation. Meanwhile, S100β is a protein component produced by central nervous system cells. This study aims to determine the presence of changes in S100β protein in adult patients with mTBI during treatment as an alternative to examination. Methods: This research is an analytic observational quantitative study with a cross-sectional study approach to investigate changes in S100β protein levels in blood serum using the ELISA method of mTBI patients in the first 3 h posttrauma (pretest) and treatment on day 1 (27 h posttrauma/posttest). The research sample consisted of 22 people. This research was conducted in the Surgery Section, Sub-Division of Neurosurgery, Dr. Moewardi Public Hospital, during September–December 2019. The data were then analyzed using a discrimination test (comparing t-test means) and a nonparametric test (Wilcoxon). Results: There was a significant difference in mean S100β change between the pretest and posttest treatments. The S100β examination results at posttest decreased to 0.0223 + 0.0029 μg/l or decreased S100β by 21.7% after treatment. Previously, it was known that the mean of S100β at pretest was 0.0285 + 0.0137 μg/l. Conclusion: There was a significant change in S100β protein levels at each examination time. Changes in S100β levels that occurred were in the form of decreased levels from 3 h to 27 h posttrauma. Thus, S100β protein can be used as a parameter to assess the clinical development of adult patients with mTBI. Moreover, none of the patients with an S100β value >0.1 μg/l was found to be the cutoff value set by SNC in adult patients with mTBI for head CT scan.

BackgroundAlthough there are eight factors known to indicate a high risk of intracranial hemorrhage (ICH) in mild traumatic brain injury (TBI), identification of the strongest of these factors may optimize the utility of brain CT in clinical practice. This study aimed to evaluate the predictors of ICH based on baseline characteristics/mode of injury, indications for brain CT, and a combination of both to determine the strongest indicator.MethodsThis was a descriptive, retrospective, analytical study. The inclusion criteria were diagnosis of mild TBI, high risk of ICH, and having undergone a CT scan of the brain. The outcome of the study was any type of ICH. Stepwise logistic regression analysis was used to find the strongest predictors according to three models: (1) injury pattern and baseline characteristics, (2) indications for CT scan of the brain, and (3) a combination of models 1 and 2.ResultsThere were 100 patients determined to be at risk of ICH based on indications for CT of the brain in patients with acute head injury. Of these, 24 (24.00%) had ICH. Model 1 found that injury due to motor vehicle crash was a significant predictor of ICH, with an adjusted OR (95% CI) of 11.53 (3.05 to 43.58). Models 2 and 3 showed Glasgow Coma Scale (GCS) score of 13 to 14 after 2 hours of observation and open skull or base of skull fracture to be independent predictors, with adjusted OR (95% CI) of 11.77 (1.32 to 104.96) and 5.88 (1.08 to 31.99) according to model 2.DiscussionOpen skull or base of skull fracture and GCS score of 13 to 14 after 2 hours of observation were the two strongest predictors of ICH in mild TBI.Level of evidenceIII.

Abstract BACKGROUND The place of serum S100B measurement in mild traumatic brain injury (mTBI) management is still controversial. Our prospective study aimed to evaluate its utility in the largest child cohort described to date. METHODS Children younger than 16 years presenting at a pediatric emergency department within 3 h after TBI were enrolled prospectively for blood sampling to determine serum S100B concentrations. The following information was collected: TBI severity determined by using the Masters classification [1: minimal or Glasgow Coma Scale (GCS) 15, 2: mild or GCS 13–15, and 3: severe or GCS <13]; whether hospitalized or not; good or bad clinical evolution (CE); whether cranial computed tomography (CCT) was prescribed; and related presence (CCT+) or absence (CCT−) of lesions. RESULTS For the 446 children enrolled, the median concentrations of S100B were 0.21, 0.31, and 0.44 μg/L in Masters groups 1, 2, and 3, respectively, with a statistically significant difference between these groups (P < 0.05). In Masters group 2, 65 CCT scans were carried out. Measurement of S100B identified patients as CCT+ with 100% (95% CI 85–100) sensitivity and 33% (95% CI 20–50) specificity. Of the 424 children scored Masters 1 or 2, 21 presented “bad CE.” S100B identified bad CE patients with 100% (95% CI 84–100) sensitivity and 36% (95% CI 31–41) specificity. Of the 242 children hospitalized, 81 presented an S100B concentration within the reference interval. CONCLUSIONS Serum S100B determination during the first 3 h of management of children with mTBI has the potential to reduce the number of CCT scans, thereby avoiding unnecessary irradiation, and to save hospitalization costs.

Concussive Injury

BackgroundEmergency departments (EDs) are usually the first point of contact, and often the only medical service available, for patients with mild traumatic brain injury (mTBI) in rural and regional areas. Clinical practice guidelines (CPGs) have been created to ensure best practice management of mTBI in EDs. Adherence to mTBI CPGs has rarely been evaluated in rural and regional areas.AimThe aim of this paper was to assess a regional health service’s adherence to their mTBI CPG.MethodsThis was a 12-month retrospective audit of 1280 ED records of patients ≥16 years presenting with mTBI to a regional Australian ED. Case selection used the Victorian Admitted Episodes Dataset codes for suspected head injury: principal diagnosis codes (S00-T98), concussive injury recorded in diagnosis codes (S06.00-S06.05) and unintentional external cause code (V00-X59). The data were collected to determine 4-hour observation rates, CT scan rates, safe discharge and appropriate referral documentation.ResultsFewer people received a CT scan than qualified (n=245, 65.3%), only 45% had 4-hour observations recorded, safe discharge was documented in 74.1% of cases and 33% received educational resources.Discussion/conclusionSeveral key elements for the management of mTBI were under-recorded, particularly 4-hour observations, safe discharge and education. Acquired brain injury clinic referrals were received in overwhelmingly fewer cases than had a CT scan (n=19, 6.3%). Overall, this study suggests that the regional health service does not currently fully adhere to the CPG and that the referral services are potentially underutilised.

Purpose: Cognitive communication deficits can be difficult to assess in individuals with mild traumatic brain injury (mTBI). However, the use of discourse analysis as a direct and sensitive metric of cognitive communication skills has shown promising clinical utility for other TBI severity levels. This exploratory study investigated discourse production in service members and veterans (SMVs) with uncomplicated mTBI with and without posttraumatic stress disorder (PTSD) and SMVs with neither mTBI or PTSD. Method: Fifteen SMVs with mTBI and PTSD, 26 with mTBI, and 25 controls with no brain injury (NBI) and without PTSD were given a wordless picture story to elicit spontaneous discourse. Discourse samples were analyzed for global coherence, word count, the use of negative emotion words, cognitive process words, nonfluencies, and story completeness. Results: Results revealed a significant difference between the mTBI ( Mdn = 3.33) and NBI ( Mdn = 3.50) groups, χ 2 (3) = 6.044, p = .017, ε 2 = .03, for global coherence. Word count differed significantly between the mTBI + PTSD ( Mdn = 135) and NBI ( Mdn = 195) groups, χ 2 (3) = 7.968, p = .006, ε 2 = .06. No other group differences were observed. Discussion: Structural features of discourse production may serve as potential markers of cognitive communication deficits in mTBI. Furthermore, PTSD may contribute to verbal fluency deficits in individuals with mTBI. Additional research is needed to develop discourse-related measures that are more sensitive to the effects of mTBI and PTSD.

Abstract Background The validated Pediatric Emergency Care Applied Network (PECARN) rule helps determine the relevance of a head computerized tomography (CT) for children with mild traumatic brain injury (mTBI). We sought to estimate the potential overuse of head CT within two Canadian emergency departments (EDs). Methods We conducted a retrospective chart review of children seen in 2016 in a paediatric Level I (site 1) and a general Level II (site 2) trauma centre. We reviewed charts to determine the appropriateness of head CT use according to the PECARN rule in a random subset of children presenting with head trauma. Simple descriptive statistics were applied. Results One thousand five hundred and forty-six eligible patients younger than 17 years consulted during the study period. Of the 203 randomly selected cases per setting, 16 (7.9%) and 24 (12%), respectively from sites 1 and 2 had a head CT performed. Based on the PECARN rule, we estimated the overuse for the younger group (<2 years) to be below 3% for both hospitals without significant difference between them. For the older group (≥2 years), the overuse rate was higher at site 2 (9.3%, 95% confidence interval [CI]: 4.8 to 17% versus 1.2%, 95% CI: 0.2 to 6.5%, P=0.03). Conclusion Both EDs demonstrated overuse rates below 10% although it was higher for the older group at site 2. Such low rates can potentially be explained by the university affiliation of both hospitals and by two Canadian organizations working to raise awareness among physicians about the overuse of diagnostic tools and dangers inherent to radiation.
