RESUMEN
OBJECTIVE: This study explores the relationship between PTSD symptoms and cognition in patients with persistent post-concussive symptoms (PPCS). METHODS: Adults with PPCS presenting to a specialized brain injury clinic provided demographic and injury information and completed the PTSD checklist for DSM-5, Generalized Anxiety Disorder Scale-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). The Montreal Cognitive Assessment (MoCA) was used to screen for possible cognitive concerns. Multiple regression analysis (MLR) adjusting for age, sex, mechanism of injury, psychiatric history, number of previous concussions, months since most recent injury, and mental health questionnaire scores was used to determine associations between PTSD and cognition. Binomial logistic regression explored the relationship between domains of the MoCA and PCL-5 scores. RESULTS: We found a negative correlation between MoCA scores, PCL-5 (ρ=-0.211, p = 0.009) and PHQ-9 (ρ=-0.187, p = 0.021) in patients with PPCS and collinearity of PCL-5 and PHQ-9 scores. Significantly higher Arousal and Reactivity cluster scores within the PCL-5 were associated with poorer scores on naming and abstract tasks on the MoCA. CONCLUSION: The association between specific PCL-5 clusters and lower MoCA scores may represent a viable target for psychotherapeutic and psychopharmacologic intervention in patients with cognitive changes associated with PPCS.
RESUMEN
Needle decompression is a mainstay intervention for tension pneumothorax in trauma medicine. It is used in combat and prehospital medicine when definitive measures are often not available or ideal. It can temporarily relieve increased intrathoracic pressure and treat a collapsed lung or great vessel obstruction. However, when done incorrectly, it can result in underlying visceral organ and vessel trauma. This is a case of an adult male who presented to the emergency department after sustaining multiple stab wounds during an altercation. On arrival, the patient had a 14-gauge angiocatheter inserted at the 4th intercostal space (ICS), left of the parasternal line traversing the right ventricle and interventricular septum and terminating in the left ventricle. The case emphasizes the importance of understanding the landmarks of performing needle decompression in increasing the procedure's efficacy and reducing iatrogenic complications.

Damage control surgery has evolved during the past 40 years. The initial cases and studies were performed at level 1 trauma centers but has now shifted to damage control at smaller hospitals. This buys time for definitive care at higher-level centers. There is a role for damage control surgery in both general surgery and trauma patients at community trauma centers. The successful implementation and completion of damage control surgery require thorough planning and a full understanding of resource limitation. Additional training or practice for infrequently performed procedures may be necessary. A systems-based approach with postoperative transfer to a higher level of care is acceptable and expected.
RESUMEN
INTRODUCTION: To improve rural and austere trauma care, hospital-based testing performed at the point of injury may shorten the time lapsed from injury to intervention. This study aimed to evaluate the use of the TEG6s device (Haemonetics(R), Clinton, PA) in a rotary wing aircraft. Prior attempts suffered from limitation related to lack of vibration mitigation. METHODS: This was an investigator-initiated, industry-supported study. Haemonetics provided a TEG6s analyzer. The device underwent a standard validation. It was secured in place on the aircraft using shipping foam for vibration mitigation. Donors provided two tubes of sample blood in one sitting. Paired studies were performed on the aircraft during level flight and in the hospital, using the Global Hemostasis with Lysis Cartridge(Haemonetics (R), Clinton, PA). Both normal and presumed pathologic samples were tested in separate phases. Paired t tests were performed. RESULTS: For normal donors, the mean R for laboratory compared with the aircraft was 6.2 minutes versus 7.2 minutes ( p = 0.025). The mean ± SD Citrated Rapid TEG Maximum Amplitude (CRT MA) was 59.3 ± 5.6 mm and 55.9 ± 7.3 mm ( p < 0.001) for laboratory and aircraft ( p < 0.001). Among normal donors, R was within normal range for 17 of 18 laboratory tests and 18 of 18 aircraft tests ( p > 0.99). During the testing of pathologic samples, the mean R time was 14.8 minutes for laboratory samples and 12.6 minutes for aircraft ( p = 0.02). Aircraft samples were classified as abnormal in 78% of samples; this was not significantly different than laboratory samples ( p = 0.5). CONCLUSION: The use of the TEG6s for inflight viscoelastic testing appears promising. While statistically significant differences are seen in some results, these values are not considered clinically significant. Classifying samples as normal or abnormal demonstrated a higher correlation. Future studies should focus on longer flight times to evaluate for LY30, takeoff, and landing effects. Overall, this study suggests that TEG6s can be used in a prehospital environment, and further study is warranted. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria; Level III.

OBJECTIVE: Do the 3.5 million US veterans, who primarily utilize private healthcare, have similar burn pit exposure and disease compared to the VA Burn Pit registry? METHODS: This is an online volunteer survey of Gulf War and Post-9/11 veterans. RESULTS: Burn pit exposure had significantly higher odds of extremity numbness, aching pain and burning, asthma, chronic obstructive pulmonary disease, interstitial lung disease, constrictive bronchiolitis, pleuritis, and pulmonary fibrosis. Chi-square did not reveal a difference in burn pit exposure and cancer diagnoses. CONCLUSIONS: These data demonstrate increased risk of neurological symptoms associated with burn pit exposure, which are not covered in the 2022 federal Promise to Address Comprehensive Toxics Act. Additional data will allow for the continued review and consideration for future medical benefits.

Nodular sebaceous gland hyperplasia in the often middle-aged to old dog is a common, benign proliferation that results in exophytic, pink to yellow, alopecic, and often multilobulated nodules. Removal is usually carried out by surgical excision. As many old dogs have comorbidities that increase the risk of anesthesia, a topical treatment is warranted. We hypothesized that the application of a solution containing nitric acid, zinc, copper, and organic acids (Verrutop®), would be a safe and efficient way to treat these nodules. Eleven dogs with a total of 29 nodules, grossly compatible with nodular sebaceous gland hyperplasia, were included in the study. Eighteen of the nodules were treated; 11 were left untreated. No anesthesia or sedation was needed. Four weeks after one application, 17/18 treated nodules had decreased by 100% in volume. There was a statistically significant difference in percentual volume change between the treated and untreated nodules from day 0 to day 28 (p < 0.0001). No serious side effects were noted. Sebaceous hyperplasia cannot always be distinguished grossly from sebaceous tumors. Cytological evaluation can be helpful, and in cases of deviant macroscopic features, local recurrence, or more aggressive behavior, the appropriate intervention would be to biopsy or excise the nodule for histopathology. Topical application of Verrutop® is an easy, low-cost, and efficient way to remove canine sebaceous gland hyperplasia with minimal side effects in cases where surgery and anesthesia are not desired.
RESUMEN
Obsessive-compulsive disorder (OCD) as a consequence of severe traumatic brain injury (TBI) has been reported in a limited number of case studies. Informed by CARE guidelines, we present the case of a boy in his late adolescence who sustained a severe TBI from a motor vehicle crash. His injuries required a prolonged stay in the hospital, including 3 weeks in the intensive care unit and a craniotomy to evacuate a large subdural haematoma. Obsessive-compulsive behaviours were first observed on discharge from the hospital and became worse over time. Compulsive behaviours were considered in light of a neuropsychological examination, and a diagnosis of OCD was attained. Sertraline was prescribed and effectively reduced the severity of OCD symptoms. Given the challenges comorbid conditions can pose to neurorehabilitation, a better understanding of patterns in OCD symptoms and brain lesions among reported cases will help guide the diagnosis of OCD among individuals with severe TBI.
