Evaluation of emergency department admissions of mass casualty patients using the revised trauma score, injury severity score, and trauma and injury severity score.

BACKGROUND: There is a need for studies evaluating prognostic scoring systems in mass trauma patients in conflict regions to predict patient prognosis for emergency surgical prioritization. In this study, we aimed to evaluate scoring systems such as the Revised Trauma Score (RTS), Injury Severity Score (ISS), and Trauma and Injury Severity Score (TRISS) in trauma patients admitted due to mass trauma in Northern Syria. METHODS: This study was a retrospective evaluation of patients admitted due to mass trauma to the emergency departments of hospitals in Northern Syria. The diagnostic efficiency of RTS, ISS, and TRISS scoring systems was evaluated in these admissions in the first half of 2021. RESULTS: The most common causes of mass trauma were bomb blast (67.3%), gunshot (28.8%), and 14 (3.9%) patients admitted with other causes. When the odds ratio (OR) was analyzed, a one-unit increase in the RTS score increased the odds of survival by a factor of 6.133, and a one-unit increase in the TRISS score increased the odds of survival by a factor of 1.057. Differently, it was found that each 1-unit increase in ISS decreased the patient's probability of survival by 0.856 units. When RTS, TRISS, and ISS scores were analyzed, the area under the ROC curve was statistically significant for all of them (p<0.001) and all of them had a diagnostic value for mortality with sensitivities of 99.0%, 94.8%, and 91.9%; specificities of 87.8%, 90.5%, and 88.6; AUC of 0.958, 0.975, and 0.958, respectively. CONCLUSION: The use of trauma scoring systems, especially TRISS, may be useful for prioritizing patients in mass casualty settings in the presence of overcapacity.

Evaluation of the predictive effects of trauma scoring systems in colorectal injuries.

INTRODUCTION: Colorectal injuries following traumas are significant causes of morbidity and mortality. This study aimed to evaluate the predictive effect of trauma scoring systems on mortality and morbidity in patients with post-traumatic colon injury. METHODS: The records of 145 patients with colon trauma treated at Seyhan State Hospital between January 1, 2010, and January 1, 2020, were retrospectively analyzed. Injury Seriousness Score (ISS), Revised Trauma Score (RTS), Trauma Injury Severity Score (TRISS), and Colon Injury Score (CIS) scores were calculated for all patients. The predictive effects of scoring systems on primary outcomes of surgical treatment, complication rates, mortality, and anastomotic leaks were evaluated. RESULTS: The mean age of the patients was 36.1 (SD ± 16.6), and the female/male ratio was 37/108. Anastomotic leakage occurred in 12 (8.2%) patients, and complications were observed in 57 (39.3%) patients. Seven (4.7%) patients died. A statistically significant relationship was observed between the increase in CIS and anastomotic leakage, morbidity, and mortality. Increases in ISS and decreases in RTS and TRISS were associated with increased morbidity and mortality, but these relationships were not statistically significant. CONCLUSION: A significant relationship was observed between the increase in CIS and anastomotic leakage, morbidity, and mortality. The study suggests the need for a specific scoring system for evaluating the prognostic status in colon traumas, as ISS, RTS, and TRISS scores were not found to be significantly predictive of outcomes in this patient population.

The relationship between computed tomography findings and ocular trauma and pediatric ocular trauma scores in pediatric globe injuries: Does imaging have prognostic and diagnostic value?

BACKGROUND: The aim of this study is to assess the relationship between computed tomography (CT) findings in open globe injuries (OGIs) in pediatric patients and the pediatric ocular trauma score (POTS) and OTS in pediatric ocular trauma. METHODS: In 34 pediatric patients with OGI, CT findings were categorized into nine main categories: Scleral irregularity, lens dislocation, abnormal vitreous density, choroid-retinal layer thickening, preseptal thickness increase, intraocular foreign body and air, vitreous hemorrhage, retinal detachment, and perforation. The relationship between different types and numbers of CT findings and the POTS and OTS was evaluated. RESULTS: The mean age of trauma was 6.6±3.1. Of the patients, 9 (26.5%) were female and 25 (73.5%) were male. The most com-mon CT findings are scleral irregularity and increased preseptal thickness (47.1%). In univariate analysis, a P<0.05 was found between 16 patients with 1 or less CT findings (median POTS value 80 [71.25-90.0]) and 11 patients with 2 or 3 CT findings (median POTS value 60 [15-70]). A P<0.05 was found between 16 patients with 1 or less CT findings (median POTS value 80 [71.25-90.0]) and 7 patients with 4 or more CT findings (median POTS value 45 [25-80]). A P > 0.05 was found between 11 patients with 2 or 3 CT findings (median POTS value 60 [15-70]) and 7 patients with 4 or more CT findings (median POTS value 45 [25-80]). No significant difference was found between the number of CT findings and OTS stages. While POTS was significant (P<0.05) in patients with ab-normal vitreous density (median 45 [30-69.6]), OTS value was not significant (P>0.05). There was no significant difference between POTS and OTS in other CT findings. CONCLUSION: The number of CT findings may assist in predicting POTS and, consequently, estimating visual prognosis in pediatric patients with OGI. In emergency situations where, sufficient clinical data are unavailable, the objective findings from CT may help in assessing the severity of ocular trauma and potentially predicting long-term visual outcomes.

Orthodontic treatment in traumatized permanent teeth: a systematic review / Tratamento ortodôntico em dentes permanentes traumatizados: uma revisão sistemática

Objective: to analyze, through literature review, the available literature on orthodontic treatment in traumatized permanent teeth. Methods: A literature search was performed in electronic databases (PubMed and SciELO) using the descriptors [tooth injuries] OR [injuries, teeth] OR [injury, teeth] OR [teeth injury] OR [injuries, tooth] OR [injury, tooth] OR [tooth injury] OR [teeth injuries] AND [orthodontics]. Observational studies and clinical trials were included, narrative reviews, laboratory and in vitro studies, case reports and series as well as articles that presented abstracts written in languages other than Portuguese, English and Spanish were excluded from the study. Two reviewers considered the eligibility, the risk of bias of the analyzed data and the qualitative synthesis of the studies included. A total of 1,322 references were found and 4 articles met all inclusion criteria and were included in the qualitative analysis. Some consequences like pulp necrosis and root resorption have been highlighted and trauma severity should be considered when orthodontically intervening in previously traumatized teeth. Final considerations: The traumatized teeth can be orthodontically treated as long as the time of tissue reorganization is respected, and the pull and periodontal conditions are followed up.(AU)

Trauma severity predictors / Preditores de gravidade no trauma

This review aimed to determine which are the indexes for early detection and evaluation of clinical and physiological deterioration of traumatized patients. A Scoping Review according to the methods proposed by Joanna Briggs Institute (JBI) was performed from February 2018 to December 2018 on LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed), and SCOPUS databases. Sixty-two studies were included, of which 43 evaluated patients with general trauma. A variety of physiological variables, such as Glasgow Coma Score, Glucose, Days in the Intensive Care Unit, Lactate, and predictor indexes - Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Revisited Trauma Score (RTS), and APACHE II were identified. The values observed in the studies among patients were compared to the ones determined by the basic literature, being called Critical Values (CV). The group of gravity indexes, besides clinical and regulatory protocols, found in this review are the solidification of the healthcare process involving the traumatized patient's responses to the actions of the healthcare team. The analysis of these indexes must be emphasized to determine, with greater reliability, the prognosis of the patient. With these data, it may be possible to effectively predict mortality rates (AU).

O objetivo desta revisão é determinar os índices para detecção precoce e avaliação clínica e fisiológica para deterioração de pacientes do trauma. Conduziu-se uma revisão de escopo de acordo com os métodos propostos pelo Joanna Briggs Institute (JBI) entre fevereiro de 2018 a dezembro de 2018 nas bases de dados LILACS (Literatura Latina-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed) e SCOPUS. Foram incluídos 62 estudos, dos quais 43 sobre trauma geral. Encontrou-se grande diversidade de variáveis fisiológicas, como Escala de Coma de Glasgow, Glicose, dias em Unidade de Terapia Intensiva, lactato e índices preditores­Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Reviseted Trauma Score (RTS) e APACHE II. Os valores observados nos pacientes dos estudos encontrados foram comparados com os da literatura básica, sendo denominados Valores Críticos (CV). O grupo de índices de gravidade encontrados neste estudo, além de protocolos reguladores e clínicos, são a solidificação do processo de cuidado envolvendo a resposta das ações da equipe em saúde ao paciente de trauma. A análise desses índices deve ser enfatizada para determinar com maior confiabilidade o prognóstico do paciente. Com esses dados, pode ser possível predizer a taxa de mortalidade com maior acurácia (AU).

The Ocular Trauma Score Underestimates Visual Recovery for the Most Severe Open-Globe Injuries.

PURPOSE: To compare visual outcomes after open-globe injury (OGI) with those predicted by the Ocular Trauma Score (OTS), and to investigate the effect of treatment with pars plana vitrectomy (PPV). DESIGN: Retrospective cohort study. SUBJECTS: Patients presenting with OGI to an academic United States ophthalmology department from 2017 to 2020. METHODS: Best-corrected visual acuity (VA) measurements at the most recent follow-up were compared with final VA predicted by the OTS, based on preoperative injury characteristics. The most recently measured VA of patients treated with PPV during initial OGI repair (primary PPV group) was compared with patients treated with PPV after initial OGI repair (secondary PPV group) and patients never treated with PPV (No PPV group). MAIN OUTCOME MEASURES: Best-corrected VA in the injured eye at last follow-up; secondary outcome measures included the occurrence of vitreous hemorrhage at any time, occurrence of retinal detachment at any time, rates of additional surgery, and rates of enucleation. RESULTS: One-hundred and thirty-three subjects with OGI were identified and analyzed. The overall rate of PPV was 32%. Predictors of worse VA at last follow-up included older age (P = 0.047) and worse presenting VA (P < 0.001). Visual acuity outcomes for eyes in OTS categories 2 to 5 did not significantly differ from OTS predictions. However, eyes in OTS category 1 had a higher likelihood of last follow-up VA of light perception (LP) to hand motion (46% in the study cohort vs. 15% predicted by the OTS, P = 0.004) and a lower likelihood of no LP (33% vs. 74%, P < 0.001). The secondary PPV group had the worst VA at presentation among the 3 groups (P = 0.016), but VA at last follow-up did not significantly differ between the study groups (P = 0.338). CONCLUSIONS: The most severe OGIs (i.e., OTS category 1) had better visual outcomes than predicted by the published OTS expectations, and secondary PPV was associated with significant visual improvement despite poor prognostic predictions. Evaluation by a vitreoretinal surgeon should be considered for all patients with severe OGI, especially those in OTS category 1.

Clinical characteristics and prognostic factors of open globe injuries in a North Spain population: a 10-year review.

OBJECTIVES: To describe the epidemiologic and clinical characteristics of open globe injuries (OGIs) treated in a tertiary hospital and analyse predictors of visual outcome. METHODS: This retrospective observational study included all patients with OGIs admitted to Cruces University Hospital between 2010 and 2020. The descriptive analysis included demographic data, type of injury classified as "rupture", "penetration", "perforation", or "intraocular foreign body", trauma mechanism and setting, injury zone, Ocular Trauma Score, delay to surgery, length of hospital stay, antibiotic prophylaxis, initial and final best corrected visual acuity (BCVA), complications and further surgery. Univariate analysis and logistic regression were performed to identify prognostic factors, based on final BCVA. RESULTS: Overall, 207 OGI cases were reported. The most common type of injuries were ruptures caused by domestic falls. Notably, 44.4% of eyes developed phthisis bulbi. In the univariate analysis, the following variables were significantly linked to visual outcome: age > 60 years, "rupture", "fall", posterior and/or combined zones of injury, lens damage, retinal/choroidal detachment, initial BCVA of no light perception, and Ocular Trauma Score ≤ 2 (p < 0.001). Delay to surgery, length of stay and further surgery did not have prognostic value. In the logistic regression, initial BCVA of no light perception (p < 0.001) and injury zone III (p = 0.005) remained significant predictors of poor outcome. CONCLUSIONS: In the population studied, most OGIs were caused by domestic falls usually affecting elderly patients with comorbidities. Visual outcome depended on patients´ specific characteristics and the nature of the trauma itself, whereas environmental factors failed to show any prognostic value.

The Association Between Computerized Tomography Findings and Ocular Trauma Score in Open Globe Injury: The Prognostic Value of Imaging.

PURPOSE: The aim of this study was to evaluate the association between CT findings and Ocular Trauma Score (OTS) in open globe injury. METHODS: In 182 eyes with open globe injury, CT findings were categorized into 5 major types: scleral irregularity with decreased globe volume, dislocation of the crystalline lens, abnormal vitreous density, thickening of the chorioretinal layer, and intraocular foreign body/air. Association between different types and number of CT findings with OTS stages were evaluated through a multivariate analysis. RESULTS: Mean age of the patients was 38 ± 8.5 years. The most common CT findings were severe scleral irregularity or globe collapse (71.9%) and abnormal vitreous density (56%). The most common OTS stages were II (44.5%) and I (30.7%). In multivariate analysis, abnormal vitreous density (odds ratio [OR] = 2.11, p < 0.001), chorioretinal thickening (OR = 1.89, p < 0.001), and intraocular foreign body/air (OR = 1.58, p = 0.001) were associated with more advanced OTS stages (I or II). Mean OTS in eyes with 1, 2, and 3 CT findings were 66 (stage III), 47 (stage II), and 37 (stage I), respectively ( p value = 0.008). Presence of 2 (OR = 2.46, p < 0.001) and 3 (OR = 2.92, p < 0.001) CT findings were associated with more advanced OTS stages (I or II). CONCLUSIONS: The type and number of CT findings may help to predict the OTS stage and visual prognosis in eyes with open globe injury.

Serum levels of copeptin predict adverse outcomes and improve risk prediction of TRISS and MGAP scores in patients with multiple trauma: A single-center prospective cohort study.

BACKGROUND: Multiple trauma deserves early prognostication and stratification. Copeptin, a precursor of vasopressin, is produced in response to stress. We examined the association between serum levels of copeptin and mortality risk in patients with multiple trauma. We aimed to also enhance the previously established Trauma-Related Injury Severity Score (TRISS) and Mechanism, GCS, Age, and Arterial Pressure (MGAP) score with the additional consideration of copeptin levels. METHODS: This single-center prospective cohort study enrolled patients who presented to the emergency department with potential major injuries. The serum levels of copeptin were measured, and the correlation to clinical severity in terms of 30-day mortality and requirement of intensive care management was analyzed. By combining copeptin levels with TRISS or MGAP, comparison between performance of the original models with the copeptin-enhanced models was performed via discrimination, calibration, and reclassification analyses. RESULTS: There was a significant increase in copeptin levels in patients who died within 30 days (median 644.4 pg/L, interquartile range [472.5, 785.9]) or were admitted to intensive care units (233.8 pg/L, [105.7, 366.4]), compared with those who survived (37.49 pg/L, [17.88, 77.68]). Adding the natural log of copeptin levels to the established TRISS and MGAP models improved the AUC of TRISS from 0.89 to 0.96, and that of MGAP from 0.82 to 0.95. Both calibrations as measured by Brier's scores and reclassification as measured by net reclassification improvement or integrated discrimination improvement demonstrated significant improvements. A Web-based calculator was built to generate predicted mortality rates of various models for convenient clinical use. CONCLUSION: Admission serum copeptin levels were correlated with clinical severity in multiple trauma. Coupling copeptin with preexisting trauma severity scores improved prediction accuracy. Copeptin shows promise as a novel biomarker for the prediction of trauma outcome. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

De un centro de trauma a un sistema de trauma en el suroccidente colombiano / From a Trauma Center to a Trauma System in Southwest Colombia

Introducción. El objetivo de este estudio fue evaluar el impacto sobre la mortalidad según el perfil de ingreso a un centro de trauma del suroccidente colombiano, como método para entender las dinámicas de atención del paciente con trauma. Métodos. Se realizó un subanálisis del registro de la Sociedad Panamericana de Trauma asociado a un centro de trauma en el suroccidente colombiano. Se analizaron los pacientes atendidos entre los años 2012 y 2021. Se compararon los pacientes con condición de ingreso directo y aquellos que ingresaron remitidos. Se hicieron análisis de poblaciones de interés como pacientes con trauma severo (ISS > 15) y pacientes con/sin trauma craneoencefálico. Se evaluó el impacto de los pacientes remitidos y su condición al ingreso sobre la mortalidad. Resultados. Se incluyeron 10.814 pacientes. La proporción de pacientes remitidos fue del 54,7 %. Los pacientes que ingresaron remitidos presentaron diferencias respecto a la severidad del trauma y compromiso fisiológico al ingreso comparado con los pacientes con ingreso directo. Los pacientes remitidos tienen mayor riesgo de mortalidad (RR: 2,81; IC95% 2,44-3,22); sin embargo, es el estado fisiológico al ingreso lo que impacta en la mortalidad. Conclusión. Los pacientes remitidos de otras instituciones tienen un mayor riesgo de mortalidad, siendo una inequidad en salud que invita a la articulación de actores institucionales en la atención de trauma. Un centro de trauma debe relacionarse con las instituciones asociadas para crear un sistema de trauma que optimice la atención de los pacientes y la oportunidad

Introduction. This study aims to evaluate the impact on mortality by admission profile to a trauma center in Southwest Colombia between direct and referred patients, as a method to understand the dynamics of trauma care.Methods. A sub-analysis of the Panamerican Trauma Society registry associated with a trauma center in Southwest Colombia was performed. Patients attended between 2012-2021 were analyzed. Patients with direct admission and referred condition were compared. Analyses of populations of interest such as patients with severe trauma (ISS > 15) and patients with/without brain trauma were made. The impact of referred patients and their admission status on mortality was evaluated. Results. A total of 10,814 patients were included. The proportion of referred patients was 54.7%. Patients admitted referred vs. with direct admission have differences regarding trauma severity and physiological compromise on admission. The referred patient has a higher risk of mortality (RR: 2.81; 95% CI 2.44-3.22). There is a high proportion of penetrating trauma by gunshot wounds. However, it is the physiological state at admission that impacts mortality. Conclusion. Patients referred from other institutions have a higher mortality risk, being a health inequity that invites the articulation of institutional actors in trauma care. A trauma center should relate to partner institutions to create a trauma system that optimizes care and timeliness

Evaluation of firearm injuries by trauma scoring systems in a secondary health care institution.

BACKGROUND: Scoring systems are widely used in trauma patients and are very important in the care of trauma patients. The objective of this study was to investigate the effectiveness of scoring systems in evaluating the patients who were brought to a hospital without a trauma center due to firearm injuries (FIs) using scoring systems, and the efficacy of these systems in identifying patients who should be treated in a trauma center. METHODS: Patients brought to Hakkari Yüksekova State Hospital due to FIs between January 2010 and December 2019 were retrospectively investigated. Patients aged 16 and over were included in the study. Patients who were brought to the hospital while deceased and those who did not respond to cardiopulmonary resuscitation in the hospital were excluded from the study. In addition, patients who underwent simple outpatient medical intervention were not included in the patient group. Patients were evaluated demographically. The mortality predictions of trauma scoring systems, which are widely used in the evaluation of trauma patients, were examined. In addition, the effectiveness of scoring systems in identifying patients who should be treated in trauma centers was investigated. RESULTS: In the study, 331 patients, 96.9% of whom were male, were evaluated. The patient group consisted of young patients and the median age was 27 (IQR, 24-29) years. A total of 74 (22.4%) patients were referred to trauma referral hospitals for diagnosis and treatment. Mortality occurred in 46 (13.9%) patients. Glasgow coma scale, injury severity score (ISS), revised trauma score, new trauma score, and trauma revised ISS were found effective for predicting mortality in patients, and scoring systems were correlated with each other. However, scoring systems were not found effective in distinguishing patients who should be treated in a trauma center. CONCLUSION: Scoring systems are significant in predicting mortality of patients with gunshot wounds. However, trauma scoring systems have not been found to be effective in distinguishing patients who require referral to a trauma center.

Rendimiento de escalas de trauma ISS, NISS y RTSen accidentes de tránsito para predecir mortalidad en un hospital de alta complejidad / Performance of ISS, NISS, and RTS trauma scales in traffic accidents to predict mortality in a high-complexity hospital

Al evaluar el rendimiento de las escalas de trauma se encontró que la sensibilidad para mortalidad varía entre el 75 % para Revised Trauma Score y el 93,8 % para Injury Severity Score y New Injury Severity Score, con una especificidad que varía entre 89,1 % y 96,8 %. Se identificó que la mejor razón de verosimilitud positiva fue para Revised Trauma Score, mientras que la mejor razón de verosimilitud negativa fue para Injury Severity Scorey New Injury Severity Score. Conclusiones. Los resultados evidencian un adecuado rendimiento de las escalas de trauma evaluadas para predecir mortalidad. La escala que presentó mejor rendimiento fue Injury Severity Score por su sensibilidad, especificidad y razón de verosimilitud positiva.

Background. The global population is on the rise and with such motor vehicle collisions, increasing the morbidity and mortality of individuals implicated in traffic accidents. The combination of clinical and paraclinical factors, as done by the different trauma scales, have an impact upon morbidity and mortality by allowing timely actions.Methods. Cross-sectional study that included patients with collision injuries in traffic accidents, treated at an emergency department from 2017 to 2018 at Hospital Universitario San José in Popayán, Colombia, a high-complexity hospital. The study defined the universe, collected sociodemographic and biological variables, and applied three trauma scales: Revised Trauma Score, Injury Severity Score, and New Injury Severity Score. Subsequently, its performance in predicting mortality was evaluated. Results. Six-hundred-fifty patients with collision injuries were treated in the emergency department with lesions due to collisions in traffic accidents; 16 deaths were reported. We found that the sensitivity varies between 75% for the Revised Trauma Score to 93.8% for the Injury Severity Score and the New Injury Severity Score. Likewise, an adequate specificity varying from 89,1% for the Injury Severity Score to 96,8% for the Revised Trauma Score. The best positive likelihood ratio was for the Revised Trauma Score. The negative likelihood ratios for the Injury Severity Score and the New Injury Severity Score were adequate.Conclusion. The results show an adequate performance of the trauma scales evaluated to predict mortality. The scale that presented the best performance was Injury Severity Score due to its sensitivity, specificity and positive likelihood ratio.

The clinical features and the factors affecting visual prognosis in pediatric open-globe injuries.

PURPOSE: To investigate clinical features and factors affecting visual prognosis after pediatric open-globe injuries. METHODS: Retrospective study of 223 children with open-globe injury was conducted. Children with final logMAR visual acuity (LVA) > 0.70 were determined as poor-vision group (group 1, n = 108) and those with final LVA ≤ 0.70 as good-vision group (group 2, n = 115). Demographic characteristics (age, gender, and damaged eye), time between trauma and surgery, ocular trauma score (OTS), follow-up time, injury size, initial and final visual acuity levels, injury type (penetrating injury, globe rupture, perforating injury, and intraocular foreign body injury), injury localization (zone 1 = within the corneal and/or limbal area, zone 2 = within the scleral area extending 5 mm back from the limbus, and zone 3 = within the area posterior to zone 2), injury cause [metal objects (fork, knife, needle), broken glass, blunt objects (ball, punch), pen-pencil, and unidentified objects], and accompanying ocular findings of the groups were detected, and comparisons were done. Additionally, effects of age, time between trauma and surgery, OTS, injury size, follow-up time, initial LVA, injury type, and injury zone on final LVA were analyzed in both groups. RESULTS: Mean age was 9.1 ± 2.0 years. There were 151 males and 72 females. Compared to group 1, group 2 had better initial and final visions (1.21 ± 0.26 vs 0.60 ± 0.28, p < 0.001 for initial LVA; 1.00 ± 0.32 vs 0.30 ± 0.13, p < 0.001 for final LVA), greater OTS (1.72 ± 0.53 vs 3.73 ± 0.61, p = 0.025), and smaller injury size (10.4 ± 3.5 vs 5.8 ± 2.4 mm, p = 0.002). Globe rupture (p = 0.015) and relative afferent pupillary defect (RAPD) (p = 0.037) were higher in group 1, while penetrating injury (p = 0.044), zone 1 involvement (p = 0.038), and metal object injury (p = 0.041) were higher in group 2. Based on multivariate analysis, the presences of globe rupture (p = 0.024) and RAPD (p = 0.035), the involvement without zone 1 (p = 0.042), and the injury without metal object (fork, knife, needle) (p = 0.046) were associated with poor final vision. Final LVA (for group 1 and group 2) was negatively correlated with OTS (r = - 0.398, p = 0.037; r = - 0.369, p = 0.040), while positively correlated with injury size (r = 0.412, p = 0.031; r = 0.318, p = 0.046) and initial LVA (r = 0.335, p = 0.043; r = 0.402, p = 0.034). CONCLUSION: In our study, poor prognostic factors affecting final vision were low OTS, poor initial vision, the presences of globe rupture and RAPD, the large injury size, the involvement without zone 1, and the injury without metal object (fork, knife, needle).

Analysis of Concomitant and Isolated Venous Injury in Military Lower Extremity Trauma.

BACKGROUND: The implications of major venous injury to the lower extremity are not well established. We aimed to determine the significance of concomitant and isolated femoropopliteal venous injury and assess the impact of surgical management strategies on limb outcomes. METHODS: The Fasciotomy and Vascular Injury Outcomes database was queried for limbs sustaining femoropopliteal arterial, venous, or concomitant injuries in Iraq or Afghanistan between 2004 and 2012. Demographics, injury patterns and severity, interventions, and outcomes were compared between patients sustaining isolated arterial injuries (IAIs) and concomitant arteriovenous injuries (AVIs). In limbs with any venous injury, outcomes were compared between those undergoing venous repair and venous ligation. RESULTS: Three hundred thirty patients (133 IAIs, 135 AVIs, 62 isolated venous injuries [IVIs]) were included. AVI was associated with greater limb injury severity: median extremity Abbreviated Injury Scale (AVI 4 vs. IAI 3, P = 0.01), Mangled Extremity Severity Score >7 (25.9% vs. 13.5%, P = 0.01), and multilevel vascular injury (6.7% vs. 0.8%, P = 0.01) and with greater fasciotomy use (83.0% vs. 69.2%, P = 0.01). No differences were present in tourniquet use/time, shunting, or nature of arterial repair. No differences in vascular or limb complications (71.1% vs. 63.9%, P = 0.21) or amputation rate (25.9% vs. 18.8%, P = 0.16) were present, though the limb deep venous thrombosis rate was 12.6% in AVIs versus 7.5% in IAIs (P = 0.17). Limbs with IVI had a 12.9% amputation and a 74.2% complication rate. Repair (n = 103) versus ligation (n = 94) of venous injuries was not associated with a difference in amputation (18.4% vs. 25.5%, P = 0.23) or limb complication rates (71.8% vs. 72.3%, P = 0.94). CONCLUSIONS: Despite higher extremity injury severity and more frequent fasciotomies, concomitant venous injury was not associated with poorer limb salvage or complications. With nontrivial amputation and complication rates, IVI is indicative of severe limb trauma. Repair of femoropopliteal venous injuries does not appear to influence limb outcomes.

Perfil neuropsicológico en pacientes con trauma craneoencefálico atendidos en un hospital de alta complejidad de Medellín, Colombia / Neuropsychological profile of patients with traumatic brain injury evaluated in a high complexity hospital in Medellin, Colombia

RESUMEN INTRODUCCIÓN: El trauma craneoencefálico (TCE) es una de las principales causas de daño cerebral y discapacidad en personas menores de 40 años. Según su severidad, se puede clasificar en leve, moderado o grave, en función de la escala de coma de Glasgow. Muchos pacientes quedan con secuelas neuropsicológicas y comportamentales que pueden afectar en mayor o menor grado su funcionalidad. El objetivo del estudio fue determinar las diferencias en el perfil neuropsicológico, las características clínicas y el compromiso funcional en pacientes con TCE según la clasificación de la severidad. METODOLOGÍA: Se realizó un estudio observacional, analítico, de corte transversal. Se revisaron las historias clínicas y los reportes neuropsicológicos de adultos con TCE evaluados por neuropsicología entre los años 2014 y 2019. Se compararon los resultados de pruebas neuropsicológicas, síndromes neuropsicológicos y funcionalidad según la severidad del TCE. RESULTADOS: Se estudiaron 48 pacientes, 38 de ellos hombres (73 %), con una mediana de edad de 35 años (RI: 25-51). En 14 casos el TCE fue leve, en 18 moderado y en 16 severo. El síndrome neuropsicológico más frente fue el amnésico (100 %), seguido del disejecutivo (79 %) y el compromiso en la atención (77 %). No se encontraron diferencias según severidad del TCE. Cuarenta y un pacientes (85 %) presentaron cambios comportamentales, 14 (29 %) experimentaron alteración en las actividades básicas de la vida diaria y 32 (68 %) en las actividades instrumentales. CONCLUSIONES: Las alteraciones neuropsicológicas, comportamentales y funcionales posteriores a un TCE son frecuentes, sin embargo, no se encontraron diferencias significativas según severidad del trauma.

ABSTRACT INTRODUCTION: Traumatic Brain Injury (TBI) is one of the main causes of brain damage and disability in people under 40 years of age. The severity of TBI can be classified as mild, moderate, or severe based on the Glasgow coma scale. Many patients are left with neuropsychological and behavioral sequelae that can affect functionality to a greater or lesser degree. The objective of the study was to determine the differences in the neuropsychological profile, clinical characteristics and functional impairment in patients with TBI according to severity. METHODOLOGY: An observational, analytical, cross-sectional study was carried out. The clinical records and neuropsychological reports of adults with TBI evaluated between 2014 and 2019 were reviewed. The results of neuropsychological tests, neuropsychological syndromes, and functionality according to severity of TBI were compared. RESULTS: 48 patients were studied, 35 were males (73 %), the median age was 35 years (IR: 25-51). In 14 TBI was mild, in 18 moderate and 16 severe. The most common neuropsychological syndrome was amnesic (100 %) followed by dysexecutive (79 %) and attentional commitment (77 %). No differences were found according to severity of TBI. 41 patients (85 %) presented behavioral changes, 14 (29 %) presented alteration in basic activities of daily life and 32 (68 %) in instrumental activities. CONCLUSIONS: Neuropsychological, behavioral and functional alterations are frequent after TBI; however, no significant differences were found according to the severity of the trauma.
