Hypothermia and the Global War on Terror: 18 Years of Minimal Progress.

INTRODUCTION: The association between hypothermia, coagulopathy, and acidosis in trauma is well described. Hypothermia mitigation starts in the prehospital setting; however, it is often a secondary focus after other life-saving interventions. The deployed environment further compounds the problem due to prolonged evacuation times in rotary wing aircraft, resource limitations, and competing priorities. This analysis evaluates hypothermia in combat casualties and the relationship to resuscitation strategy with blood products. METHODS: Using the data from the Department of Defense Joint Trauma Registry from 2003 to 2021, a retrospective analysis was conducted on adult trauma patients. Inclusion criteria was arrival at the first military treatment facility (MTF) hypothermic (<95ºF). Study variables included: mortality, year, demographics, battle vs non-battle injury, mechanism, theater of operation, vitals, and labs. Subgroup analysis was performed on severely injured (15 < ISS < 75) hypothermic trauma patients resuscitated with whole blood (WB) vs only component therapy. RESULTS: Of the 69,364 patients included, 908 (1.3%) arrived hypothermic; the vast majority of whom (N = 847, 93.3%) arrived mildly hypothermic (90-94.9°F). Overall mortality rate was 14.8%. Rates of hypothermia varied by year from 0.7% in 2003 to 3.9% in 2014 (P <0.005). On subgroup analysis, mortality rates were similar between patients resuscitated with WB vs only component therapy; though base deficit values were higher in the WB cohort (-10 vs -6, P < 0.001). CONCLUSION: Despite nearly 20 years of combat operations, hypothermia continues to be a challenge in military trauma and is associated with a high mortality rate. Mortality was similar between hypothermic trauma patients resuscitated with WB vs component therapy, despite greater physiologic derangements on arrival in patients who received WB. As the military has the potential to conduct missions in environments where the risk of hypothermia is high, further research into hypothermia mitigation techniques and resuscitation strategies in the deployed setting is warranted.

Effects of Gynecomastia Surgery on Readiness and Return to Duty in an Active Duty Military Population.

INTRODUCTION: Simple mastectomies are routinely performed in the military health care system as gynecomastia can cause significant pain and discomfort when wearing body armor. Postoperative recovery negatively impacts personnel readiness. In this study, we sought to study time to return to duty in active duty service members who undergo surgery for gynecomastia. METHODS AND MATERIALS: We conducted a single-center retrospective review of active duty patients undergoing a surgical operation for gynecomastia from July 2020-June 2022. A total of 96 patients were included. Our primary outcome of interest was time from surgery to return to duty. A multivariate analysis was performed to assess for factors independently associated with surgical complications including patient demographics and operative techniques. RESULTS: The median number of days to return to duty after surgery was 28 days (IQR 13-37). The median loss of duty days because of gynecomastia without surgery was 19 days (IQR 10-21), which was different on the Mann-Whitney U test. Surgical complications were observed in 19 patients (19.7%) with the most common complications being seroma (11), hematoma (4), nipple-areolar complex necrosis (2), and infection (2). Patients with a complication have significantly more time to return to duty (28 vs. 49 days, P < .001). Risk factors associated with an increased risk of complication include ranks E1-E4, behavioral health diagnosis, "open" vs. "combined" technique with liposuction, length of operation greater than 58 minutes, and excised breast mass greater than 17.9 g. CONCLUSIONS: Gynecomastia surgery is associated with a detriment to personnel readiness. Surgery should be reserved for patients with severe symptoms that prevent the performance of daily duties. Furthermore, factors associated with an increased risk for complications include ranks E1-E5, behavioral health diagnosis, length of operation >58 minutes, and excised breast mass >17.9 g. The operating surgeon should be mindful of these factors.

Burkitt-type lymphoma incidentally found as the cause of acute appendicitis: a case report and review of literature.

BACKGROUND: Appendectomy remains one of the most common emergency operations. Recent research supports the treatment of uncomplicated appendicitis with antibiotics alone. While nonoperative management of appendicitis may be safe in some patients, it may result in missed neoplasms. We present a case of acute appendicitis where the final pathology resulted in a diagnosis of a Burkitt-type lymphoma. CASE PRESENTATION: An 18-year-old male presented to the emergency department with 24 h of right lower quadrant pain with associated urinary retention, anorexia, and malaise. Past medical history was significant for intermittent diarrhea and anal fissure. He exhibited focal right lower quadrant tenderness. Workup revealed leukocytosis and CT uncovered acute appendicitis with periappendiceal abscess and no appendicolith. Laparoscopic appendectomy was performed and found acute appendicitis with associated abscess abutting the rectum and bladder. Pathology of the resected appendix reported acute appendicitis with evidence of Burkitt-type lymphoma. A PET scan did not reveal any residual disease. Hematology/oncology was consulted and chemotherapy was initiated with an excellent response. CONCLUSIONS: Appendiceal lymphomas constitute less than 0.1% of gastrointestinal lymphomas. Primary appendix neoplasms are found in 0.5-1.0% of appendectomy specimens following acute appendicitis. In this case, appendectomy allowed for prompt identification and treatment of an aggressive, rapidly fatal lymphoma resulting in complete remission.

Effect of Various OR Noise on Fine Motor Skills, Cognition, and Mood.

BACKGROUND: The amalgam of noises inherent to the modern-day operating room has the potential of diluting surgeon concentration, which could affect surgeon performance and mood and have implications on quality of care and surgeon resilience. OBJECTIVE: Evaluate the impact of operating room environmental noises on surgeon performance including fine motor dexterity, cognition, and mood. METHODS: 37 subjects were tested under three different environmental noise conditions including silence, a prerecorded soundtrack of a loud bustling operating room, and with background music of their choosing. We used the Motor Performance Series to test motor dexterity, neuropsychological tests to evaluate cognitive thinking, and Profile of Mood States to test mental well-being. RESULTS: Our results showed that typical operating room noise had no impact on motor dexterity but music improved the speed and precision of movements and information processing skills. Neurocognitive testing showed a significant decrement from operating room noise on verbal learning and delayed memory, whereas music improved complex attention and mental flexibility. The Profile of Mood States found that music resulted in a significant decrease in feelings of anger, confusion, fatigue, and tension along with decreased total mood disturbance, which is a measure of psychological distress. Loud operating room noise had a negative impact on feelings of vigor but no increase in total mood disturbance. CONCLUSION: Our results suggest that loud and unnecessary environmental noises can be distracting to a surgeon, so every effort should be taken to minimize these. Music of the surgeons' choosing does not negatively affect fine motor dexterity or cognition and has an overall positive impact on mood and can therefore be safely practiced if desired.
