RESUMO
RESUMEN La uretrografía retrógrada es la técnica de referencia (gold standard) utilizada clásicamente para hacer diagnóstico de lesiones de uretra. En este contexto se presenta un caso en el que se realizó tomografía computarizada con reconstrucción 3D con contraste intravenoso y endouretral, pudiendo reconstruir la uretra en toda su extensión en forma tridimensional. De esta manera se arribó al diagnóstico de certeza de la lesión de uretra. Como ventaja del método se menciona la posibilidad de diagnosticar ‒ con un solo estudio por imágenes‒ lesiones de todo el tracto urinario, órganos sólidos, huecos y lesión del anillo pélvico asociados al traumatismo, con una alta sensibilidad y especificidad sin necesidad de requerir otros estudios complementarios.
ABSTRACT Retrograde urethrography is the gold standard method for the diagnosis of urethral injuries. In this setting, we report the use of computed tomography with intravenous injection and urethral administration of contrast medium and 3D reconstruction of the entire urethra. The definitive diagnosis of urethral injury was made. The advantage of this method is the possibility of making the diagnosis of traumatic injuries of the entire urinary tract, solid organs, hollow viscera and of the pelvic ring within a single imaging test, with high sensitivity and specificity, with no need to perform other complementary tests.

Some studies report neurological lesions in patients with genetic skeletal disorders (GSDs). However, none of them describe the frequency of neurological lesions in a large sample of patients or investigate the associations between clinical and/or radiological central nervous system (CNS) injury and clinical, anthropometric and imaging parameters. The project was approved by the institution's ethics committee (CAAE 49433215.5.0000.0022). In this cross-sectional observational analysis study, 272 patients aged four or more years with clinically and radiologically confirmed GSDs were prospectively included. Genetic testing confirmed the diagnosis in the FGFR3 chondrodysplasias group. All patients underwent blinded and independent clinical, anthropometric and neuroaxis imaging evaluations. Information on the presence of headache, neuropsychomotor development (NPMD), low back pain, joint deformity, ligament laxity and lower limb discrepancy was collected. Imaging abnormalities of the axial skeleton and CNS were investigated by whole spine digital radiography, craniocervical junction CT and brain and spine MRI. The diagnostic criteria for CNS injury were abnormal clinical and/or radiographic examination of the CNS. Brain injury included malacia, encephalopathies and malformation. Spinal cord injury included malacia, hydrosyringomyelia and spinal cord injury without radiographic abnormalities. CNS injury was diagnosed in more than 25% of GSD patients. Spinal cord injury was found in 21.7% of patients, and brain injury was found in 5.9%. The presence of low back pain, os odontoideum and abnormal NPMD remained independently associated with CNS injury in the multivariable analysis. Early identification of these abnormalities may have some role in preventing compressive CNS injury, which is a priority in GSD patients.

Tracheal injury can occur as a rare complication of endotracheal intubation, associated with multiple anatomical and mechanical factors that have been described; however, the actual incidence is unknown due to the few series of documented cases that are reported worldwide. It is considered a fatal complication when it occurs and a diagnosis is not established in a timely manner. We present the case of a patient with active SARS-CoV-2 infection and a history of congenital malformation, who presented a tracheal lesion secondary to reintubation as a radiological finding.
La lesión traqueal puede ocurrir como complicación rara de una intubación endotraqueal, asociada a múltiples factores que han sido descritos de tipo anatómico y mecánico, sin embargo, la incidencia real se desconoce por las pocas series de casos documentados que se reportan a nivel mundial. Considera como una complicación mortal cuando se presenta y no se establece un diagnóstico de forma oportuna. Presentamos el caso de un paciente con infección activa de SARS-CoV-2 y antecedente de malformación congénita, que presentó como hallazgo radiológico una lesión traqueal secundaria a reintubación.

Abstract Trauma is a complex pathology that requires an experienced multidisciplinary team with an inherent quick decision-making capacity, given that a few minutes could represent a matter of life or death. These management decisions not only need to be quick but also accurate to be able to prioritize and to efficiently control the injuries that may be causing impending hemodynamic collapse. In essence, this is the cornerstone of the concept of damage control trauma care. With current technological advances, physicians have at their disposition multiple diagnostic imaging tools that can aid in this prompt decision-making algorithm. This manuscript aims to perform a literature review on this subject and to share the experience on the use of whole body computed tomography as a potentially safe, effective and efficient diagnostic tool in cases of severely injured trauma patients regardless of their hemodynamic status. Our general recommendation is that, when feasible, perform a whole body computed tomography without interrupting ongoing hemostatic resuscitation in cases of severely injured trauma patients with or without signs of hemodynamic instability. The use of this technology will aid in the decision-making of the best surgical approach for these patients without incurring any delay in definitive management and/or increasing significantly their radiation exposure.

BACKGROUND: Decreases in the rates of traditional autopsy (TA) negatively impact traumatology, especially in the areas of quality improvement and medical education. To help enhance the understanding of trauma-related mortality, a number of initiatives in imaging autopsy (IA) were conceived, including the postmortem computed tomography ("CATopsy") project at our institution. Though IA is a promising concept, few studies directly correlate TA and IA findings quantitatively. Here, we set out to increase our understanding of the similarities and differences between key findings on TA and IA in a prospective fashion with blinding of pathologist and radiologist evaluations. METHODS: A prospective study of TA versus IA was conducted at an Academic Level I Trauma Center (June 2001-May 2010). All decedents underwent a postmortem, whole-body, noncontrast computed tomography that was interpreted by an independent, blinded, board-certified radiologist. A blinded, board-certified pathologist then performed a TA. Autopsy results were grouped into predefined categories of pathologic findings. Categorized findings from TA and IA were compared by determining the degree of agreement (kappa). The χ(2) test was used to detect quantitative differences in "potentially fatal" findings (eg, aortic trauma, splenic injury, intracranial bleeding, etc) between TA and IA. RESULTS: Twenty-five trauma victims (19 blunt; 9 female; median age 33 years) had a total of 435 unique findings on either IA or TA grouped into 34 categories. The agreement between IA and TA was worse than what chance would predict (kappa = -0.58). The greatest agreement was seen in injuries involving axial skeleton and intracranial/cranio-facial trauma. Most discrepancies were seen in soft tissue, ectopic air, and "incidental" categories. Findings determined to be "potentially fatal" were seen on both TA/IA in 48/435 (11%) instances with 79 (18%) on TA only and 53 (12%) on IA only. TA identified more "potentially fatal" solid organ and heart/great vessel injuries, while IA revealed more spine injuries, "potentially fatal" procedure-related findings, and the presence of ectopic air/fluid. CONCLUSION: This limited study does not support substitution of noncontrast, computed tomography-based IA for TA. Our quantitative analyses suggest that TA and IA evaluations may be complementary and synergistic when performed concurrently. There are potential benefits to using IA in trauma process/quality improvement and in educational settings. Further research should focus on the value (and limitations) of the information provided by IA in the absence of TA.

BACKGROUND: Older adult trauma patients are at increased risk of poor outcome, both immediately after injury and beyond hospital discharge. Identifying patients early in the hospital stay who are at increased risk of death after discharge can be challenging. METHODS: Retrospective analysis was performed using our trauma registry linked with the social security death index from 2010 to 2014. Age was categorized as 18 to 64 and 65 years or older. We calculated mortality rates by age category then selected elderly patients with mechanism of injury being a fall for further analysis. Computed Tomography Abbreviated Assessment of Sarcopenia for Trauma (CAAST) was obtained by measuring psoas muscle cross-sectional area adjusted for height and weight. Kaplan-Meier survival analysis was performed, and proportional hazards regression modeling was used to determine independent risk factors for in-hospital and out-of-hospital mortality. RESULTS: A total of 23,622 patients were analyzed (16,748, aged 18-64 years; and 6,874, aged 65 or older). In-hospital mortality was 1.96% for ages 18 to 64 and 7.19% for age 65 or older (p < 0.001); postdischarge 6-month mortality was 1.1% for ages 18 to 64 and 12.86% for age 65 or older (p < 0.001). Predictors of in-hospital and postdischarge mortality for ages 18 to 64 and in-hospital mortality for ages 65 or older group included injury characteristics such as ISS, admission vitals, and head injury. Predictors of postdischarge mortality for age 65or older included skilled nursing before admission, disposition, and mechanism of injury being a fall. A total of 57.5% (n = 256) of older patients who sustained a fall met criteria for sarcopenia. Sarcopenia was the strongest predictor of out-of-hospital mortality in this cohort with a hazard ratio of 4.77 (95% confidence interval, 2.71-8.40; p < 0.001). CONCLUSION: Out of hospital does not assure out of danger for the elderly. Sarcopenia is a strong predictor of 6-month postdischarge mortality for older adults. The CAAST measurement is an efficient and inexpensive measure that can allow clinicians to target older trauma patients at risk of poor outcome for early intervention and/or palliative care services. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.

BACKGROUND: Dynamic and efficient resuscitation strategies are now being implemented in severely injured hemodynamically unstable (HU) patients as blood products become readily and more immediately available in the trauma room. Our ability to maintain aggressive resuscitation schemes in HU patients allows us to complete diagnostic imaging studies before rushing patients to the operating room (OR). As the criteria for performing computed tomography (CT) scans in HU patients continue to evolve, we decided to compare the outcomes of immediate CT versus direct admission to the OR and/or angio suite in a retrospective study at a government-designated regional Level I trauma center in Cali, Colombia. METHODS: During a 2-year period (2012-2013), blunt and penetrating trauma patients (≥ 15 years) with an Injury Severity Score (ISS) greater than 15 who met criteria of hemodynamic instability (systolic blood pressure [SBP] <100 mm Hg and/or heart rate >100 beats/min and/or ≥ 4 U of packed red blood cells transfused in the trauma bay) were included. Isolated head trauma and patients who experienced a prehospital cardiac arrest were excluded. The main study outcome was mortality. RESULTS: We reviewed 171 patients. CT scans were performed in 80 HU patients (47%) immediately upon arrival (CT group); the remaining 91 patients (53%) went directly to the OR (63 laparotomies, 20 thoracotomies) and/or 8 (9%) to the angio suite (OA group). Of the CT group, 43 (54%) were managed nonoperatively, 37 (46%) underwent surgery (15 laparotomies, 3 thoracotomies), and 2 (5%) underwent angiography (CT OA subgroup). None of the mortalities in the CT group occurred in the CT suite or during their intrahospital transfers. CONCLUSION: There was no difference in mortality between the CT and OA groups in HU patients. CT scan was attainable in 47% of HU patients and avoided surgery in 54% of the cases. Furthermore, CT scan was helpful in deciding definitive/specific surgical management in 46% scanned HU patients who necessitated surgery after CT. LEVEL OF EVIDENCE: Therapy/care management study, level IV.
