RESUMEN
INTRODUCTION: Current literature contains an extensive number of analyses on the diagnostic value and utilization of the direct rectal exam in trauma patients. Presently, ATLS recommends the application of the digital rectal exam in trauma patients following a primary assessment of traumatic injuries. We aim to assess the validity and diagnostic value of the digital rectal exam in trauma populations. METHODS: PubMed, Google Scholar, EMBASE, ProQuest, and CINAHL databases were searched for studies from the date of database conception to August 6th, 2022. Studies that assessed the validity of the digital rectal exam performed in the emergency department or trauma bay, in both adult and pediatric trauma patients were included. Study outcomes and measurements of validity were summarized and compared. RESULTS: A total of 9 studies met inclusion criteria for both adult and pediatric trauma populations. The sensitivity of the digital rectal exam in detecting both spinal cord and urethral injuries in adult trauma populations ranged from 0 to 50%, while the sensitivity in detecting gastrointestinal injuries ranged from 0% to 51%. When compared to other clinical indicators, the digital rectal exam was consistently worse at detecting injuries. Within the pediatric trauma populations, the digital rectal exam resulted in high false negative rates ranging from 66% to 100%, failing to detect all urethral and gastrointestinal injuries and pelvic fractures. CONCLUSION: The use of digital rectal exams in trauma patients illustrates limited to no validity and reliability in assessing pertinent injuries and does not influence the management of injuries. Trauma societies should consider creating guidelines and algorithms to clarify the use of digital rectal exams in specific situations and injury types.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple systems of the body. Recent research on the gut microbiota dysbiosis associated with SLE patients has gained traction and warranted further exploration. It has not been determined whether the change in the gut microbiota is a cause of SLE or a symptom of SLE. However, based on the physiological and pathophysiological role of the bacteria in the gut microbiome, as levels of the bacteria rise or fall, symptomatology in SLE patients could be affected. This review analyzes the recent studies that examined the changes in the gut microbiota of SLE patients and highlights the correlations between gut dysbiosis and the clinical manifestations of SLE. A systematic search strategy was developed by combining the terms "SLE," "systemic lupus erythematosus," and "gut microbiome." Biomedical Reference Collection, CINAHL, Medline ProQuest, and PubMed Central databases were searched by combining the appropriate keywords with "AND." Only full-text, English-language articles were searched. The articles were restricted from 2013 to 2023. Only peer-reviewed controlled studies with both human and animal trials were included in this scoping review. Review articles, non-English articles, editorials, case studies, and duplicate articles from the four databases were excluded.â¯Various species of bacteria were found to be positively or negatively associated with SLE gut microbiomes. Among the bacterial species increased were Clostridium, Lactobacilli, Streptococcus, Enterobacter, and Klebsiella. The bacterial species that decreased were Bifidobacteria, Prevotella, and the Firmicutes/Bacteroidetes ratio. Literature shows that Clostridium is one of several bacteria found in abundance, from pre-disease to the diseased state of SLE. Lachnospiraceae and Ruminococcaceae are both part of the family of butyrate-producing anaerobes that are known for their role in strengthening the skin barrier function and, therefore, may explain the cutaneous manifestations of SLE patients. Studies have also shown that the Firmicutes/Bacteroidetes ratio is significantly depressed, which may lead to appetite changes and weight loss seen in SLE patients. Based on the established role of these bacteria within the gut microbiome, the disruption in the gut ecosystem could explain the symptomatology common in SLE patients. By addressing these changes, our scoping review encourages further research to establish a true causal relationship between the bacterial changes in SLE patients as well as furthering the scope of microbiota changes in other systems and autoimmune diseases.
RESUMEN
Lyme disease is a tick-borne illness known for its ability to cause multi-systemic manifestations. It can affect several different systems, including neurological, musculoskeletal, and dermatological systems. However, one of the most concerning biological systems affected is the cardiac system. Lyme carditis typically presents with varying degrees of atrioventricular (AV) block. Additionally, current literature also endorses atypical manifestations, including but not limited to atrial fibrillation and bundle branch blocks. These atypical manifestations are important as they can be the first presenting symptoms in patients with Lyme disease. Therefore, educating clinicians on various signs, symptoms, and manifestations of Lyme carditis remains paramount in reducing morbidity and mortality. We conducted a literature review using PubMed, MEDLINE, and CINAHL, collecting a total of 13 articles to gather information on atypical manifestations of Lyme carditis. This literature review serves to summarize the current research and studies describing these cardiac manifestations and the cardiac pathophysiology associated with Lyme disease. These findings aim to contribute to the expanding understanding of Lyme carditis, subsequently preventing long-term effects through prompt diagnosis and treatment.
RESUMEN
The collection of blood in the subdural layer within the cranium is classified as a subdural hematoma. Prevalence of subdural hematomas is most common among older populations with the current standard of treatment being invasive surgical evacuation for patients presenting with acute subdural hematomas with a midline shift greater than 5 mm on computed tomography (CT).Tranexamic acid (TXA) has been identified as an alternative, non-invasive option to treat patients presenting with subdural hematoma who are not suitable for surgical intervention. The presenting case involves a 90-year-old female who arrived with a code stroke with the chief complaint of right lower extremity weakness. A stroke series CT panel revealed a left frontal multiloculated subdural hematoma, measuring 130 mL with mass effect and a midline shift of 7 mm. The patient was recommended a craniotomy for hematoma evacuation or access to hospice for comfort care. A second opinion resulted in the administration of TXA. After the full completion of a TXA course, the patient achieved baseline mobility. The final measurements revealed a final hematoma volume of 10 mL and a midline shift of less than 2 mm. Current literature, as well as the case described, has begun demonstrating the efficacy of the usage of TXA in the reabsorption of subdural hematomas and should encourage further exploration into society guidelines for the usage of TXA as a non-invasive alternative to treat subdural hematomas.
RESUMEN
INTRODUCTION: Despite the increasing amount of evidence supporting its use, cell salvage (CS) remains an underutilized resource in operative trauma care in many hospitals. We aim to evaluate the utilization of CS in adult trauma patients and associated outcomes to provide evidence-based recommendations. METHODS: A systematic review was conducted using PubMed, Google Scholar, and CINAHL. Articles evaluating clinical outcomes and the cost-effectiveness of trauma patients utilizing CS were included. The primary study outcome was mortality rates. The secondary outcomes included complication rates (sepsis and infection) and ICU-LOS. The tertiary outcome was the cost-effectiveness of CS. RESULTS: This systematic review included 9 studies that accounted for a total of 1119 patients that received both CS and allogeneic transfusion (n = 519), vs allogeneic blood transfusions only (n = 601). In-hospital mortality rates ranged from 13% to 67% in patients where CS was used vs 6%-65% in those receiving allogeneic transfusions only; however, these findings were not significantly different (P = .21-.56). Similarly, no significant differences were found between sepsis and infection rates or ICU-LOS in those patients where CS usage was compared to allogeneic transfusions alone. Of the 4 studies that provided comparisons on cost, 3 found the use of CS to be significantly more cost-effective. CONCLUSIONS: Cell salvage can be used as an effective method of blood transfusion for trauma patients without compromising patient outcomes, in addition to its possible cost advantages. Future studies are needed to further investigate the long-term effects of cell salvage utilization in trauma patients.

INTRODUCTION: Despite the increase in electric vehicle sales in the US, their impact on injuries and fatalities is still understudied. We aim to evaluate injuries and fatalities associated with electric vehicle collisions in the US. METHODS: The study utilized electric vehicle injury and fatality data from the Fatality Analysis Reporting System (FARS). All electric vehicle models available within the FARS database and sold in the US from 2014 to 2020 were selected. Electric vehicle models were matched to analogous motor vehicles when possible. RESULTS: No significant increase in electric vehicle fatality per capita (FPC) was found during the study period (2014: .41 vs 2020: 1.42, per 100 000 electric cars, P = .080). However, 82% of all fatalities occurred on non-intersectional local roadways with 46% occurring in the presence of speeding, 14% in the presence of fire, and 38% involving a driver with an elevated blood alcohol content (BAC). The Tesla Model S, Kia Niro, and Hyundai IONIQ accounted for the most fatality per capita (17.89 vs 10.27 vs 8.42, per 100 000 electric cars). Upon comparison of electric vehicles to analogous motor vehicles produced within the same year, the Hyundai IONIQ had a significantly lower FPC compared to the Hyundai Elantra (7.33 vs 23.51, per 100 000 electric cars P = .034). CONCLUSION: While no significant increase in electric vehicle fatality per capita (FPC) was found, the total number of electric vehicle fatalities did increase significantly during the study period (2014-2020). Furthermore, a significant proportion of these fatalities is directly related to speeding, fire, and intoxicated driving.
