Abstract
BACKGROUND Traumatic pneumopericardium (PPC) is a rare clinical entity associated with chest trauma, resulting from a pleuropericardial connection in the presence of a pneumothorax, interstitial air tracking along the pulmonary perivascular sheaths from ruptured alveoli to the pericardium, or direct trachea-bronchial-pericardial communication. Our objectives were to describe the modern management approach to PPC and to identify variables that could improve survival with severe thoracic injury. METHODS We conducted a retrospective study of the trauma registry between 2015 and 2022 at a Level I verified adult trauma center for all patients with PPC. Demographics, injury patterns, and treatment characteristics were compared between blunt and penetrating trauma. This study focused on the management strategies and the physiologic status regarding PPC and the development of tension physiology. The main outcome measure was operative versus nonoperative management. RESULTS Over a seven-year period, there were 46,389 trauma admissions, of which 488 patients had pneumomediastinum. Eighteen patients were identified with PPC at admission. Median age was 39.5 years (range, 18-77 years), predominantly male (n = 16, 89 %), Black (n = 12, 67 %), and the majority from blunt trauma (78 %). Half had subcutaneous emphysema on presentation while 39 % had recognizable pneumomediastinum on chest x-ray. Tube thoracostomy was the most common intervention in this cohort (89 %). Despite tube thoracostomy, tension PPC was observed in three patients, two mandating emergent pericardial windows for progression to tension physiology, and the remaining requiring reconstruction of a blunt tracheal disruption. The majority of PPC patients recovered with expectant management (83 %), and no deaths were directly related to PPC. CONCLUSIONS Traumatic PPC is a rare radiographic finding with the majority successfully managed conservatively in a monitored ICU setting. These patients often have severe thoracic injury with concomitant injuries requiring thoracostomy alone; however, emergent surgical intervention may be required when PPC progresses to tension physiology to improve overall survival.

Abstract
BACKGROUND Traumatic brain injury (TBI) requires rapid management to avoid secondary injury or death. This study evaluated if a simple schema for quickly interpreting CT head (CTH) imaging by trauma surgeons and trainees could be validated to predict need for neurosurgical intervention (NSI) or death from TBI within 24 hours. METHODS We retrospectively reviewed TBI patients presenting to our trauma center in 2020 with blunt mechanism and GCS ≤ 12. Primary independent variables were presence of 7 normal findings on CTH (CSF at foramen magnum, open fourth ventricle, CSF around quadrigeminal plate, CSF around cerebral peduncles, absence of midline shift, visible sulci/gyri, and gray-white differentiation). Trauma surgeons and trainees separately evaluated each patient's CTH, scoring findings as normal or abnormal. Primary outcome was NSI/death in 24 hours. RESULTS Our population consisted of 444 patients; 21.4% received NSI or died within 24 hours. By trainees' interpretation, 5.8% of patients without abnormal findings had NSI/death vs 52.0% of patients with ≥1 abnormality; attending interpretation was 8.7% and 54.9%, respectively (P < .001). Sulci/gyri effacement, midline shift, and cerebral peduncle effacement maximized sensitivity and specificity for predicting NSI/death. Considering pooled results, when ≥1 of those 3 findings was abnormal, sensitivity was 77.89%, specificity was 80.80%, positive predictive value was 52.48%, and negative predictive value was 93.07%. DISCUSSION Any single abnormality in this schema significantly predicted a large increase in NSI/death in 24 hours in TBI patients, and three particular findings were most predictive. This schema may help predict need for intervention and expedite management of moderate/severe TBI.

Abstract
BACKGROUND Traumatic vascular injuries of the lower extremity in the pediatric population are uncommon but can result in significant morbidity. The objective of this study is to demonstrate our experience with these injuries by describing patterns of traumatic vascular injury, the initial management, and data regarding early outcomes. METHODS In total, 506 patients presented with lower extremity vascular injury between January 1, 2009 and January 1, 2021 to Grady Memorial Hospital, an urban, adult Level I trauma center in Atlanta, Georgia. Thirty-two of the 506 patients were aged less than 18 years and were evaluated for a total of 47 lower extremity vascular injuries. To fully elucidate the injury patterns and clinical course in this population, we examined patient demographics, mechanism of injury, type of vessel injured, surgical repair performed, and early outcomes and complications. RESULTS The median (interquartile range) age was 16 (2) years (range, 3-17 years), and the majority were male (n = 29, 90.6%). Of the vascular injuries identified, 28 were arterial and 19 were venous. Of these injuries, 14 patients had combined arterial-venous injuries. The majority of injuries were the result of a penetrating injury (n = 28, 87.5%), and of these, all but 2 were attributed to gunshot wounds. Twenty-seven vascular interventions were performed by nonpediatric surgeons: 11 by trauma surgeons, 13 by vascular surgeons, 2 by orthopedic surgeons, and 1 by an interventional radiologist. Two patients required amputation: 1 during the index admission and 1 delayed at 3 months. Overall survival was 96.9%. CONCLUSIONS Vascular injuries as the result of trauma at any age often require early intervention, and we believe that these injuries in the pediatric population can be safely managed in adult trauma centers with a multidisciplinary team composed of trauma, vascular, and orthopedic surgeons with the potential to decrease associated morbidity and mortality from these injuries.

Abstract
PURPOSE Hepatic arterioportal fistula (HAPF) is an uncommon complication of hepatic trauma, which can manifest with abdominal pain and the sequelae of portal hypertension months to years after injury. The purpose of this study is to present cases of HAPF from our busy urban trauma center and make recommendations for management. METHODS One hundred and twenty-seven patients with high-grade penetrating liver injuries (American Association for the Surgery of Trauma [AAST] - Grades IV-V) between January 2019 and October 2022 were retrospectively reviewed. Five patients were identified with an acute hepatic arterioportal fistula following abdominal trauma from our ACS-verified adult Level 1 trauma center. Institutional experience with overall surgical management is described and reviewed with the current literature. RESULTS Four of our patients presented in hemorrhagic shock requiring emergent operative intervention. The first patient had postoperative angiography and coil embolization of the HAPF. Patients 2 through 4 underwent damage control laparotomy with temporary abdominal closure followed by postoperative transarterial embolization with gelatin sponge particles (Gelfoam) or combined Gelfoam/n-butyl cyanoacrylate. The final patient went directly for angiography and Gelfoam embolization after identification of the HAPF. All 5 patients had resolution of HAPF on follow-up imaging with continued post management for traumatic injuries. CONCLUSION Hepatic arterioportal fistula can present as a complication of hepatic injury and manifest with significant hemodynamic aberrations. Although surgical intervention was required to achieve hemorrhage control in almost all cases, management of HAPF in the setting of high-grade liver injuries was achieved successfully with modern endovascular techniques. A multidisciplinary approach to such injuries is necessary to optimize care in the acute setting following traumatic injury.

Abstract
BACKGROUND Firearm-related injury (FRI) became the leading cause of death among children/adolescents in 2019. PURPOSE This study sought to determine changes over time in the population of adolescents affected by FRI in Atlanta, Georgia, such that high risk cohorts could be identified. RESEARCH DESIGN City-wide retrospective cohort review. STUDY SAMPLE Adolescent victims (age 11-21 years of age) of FRI, defined by ICD9/10 codes, in Atlanta, Georgia. DATA ANALYSIS Descriptive, multivariate and time series analysis. RESULTS There were 1,453 adolescent FRI victims in this time period, predominantly Black (86%) and male (86.6%). Unintentional injury was higher among ages 11-14 years (43.1%) compared to 15-17 years (10.2%) and 18-21 years (9.3%) (P < .01). FRI affecting females increased at a rate of 8.1 injuries/year (P < .01), and unintentional injuries increased at by 7.6/year (P < .01). Mortality declined from 16% in 2016 to 7.7% in 2021. CONCLUSION Our data provides evidence for firearm policy reform. Interventions should target prevention of intentional injury among AQ4 females and seek to reverse the trend in unintentional injuries.

Abstract
PURPOSE Bullet embolization is a rare but dangerous phenomenon. Based on the location of embolization, migration of bullets can cause limb or intra-abdominal ischemia, pulmonary infarction, cardiac valve injury, or cerebrovascular accident. Bullet emboli can present a diagnostic challenge given the varied nature of complications based on location of embolization, which may not coincide with the site of initial injury. The purpose of this study is to present several cases of bullet embolization from our busy urban trauma center and make recommendations for management. METHODS We present 3 cases of bullet embolization seen in injured patients at our Level 1 trauma center. We describe our management of these injuries and make recommendations for management in the context of our institutional experience and comment on the available literature regarding bullet embolization. RESULTS Two of our patients presented in extremis and required operative intervention to achieve stability. The intravascular missile was discovered intraoperatively in one patient and removed in the operating room, while the missile was discovered on postoperative imaging in another patient and again removed operatively after an unsuccessful attempt at minimally invasive retrieval. Our third patient remained hemodynamically stable throughout his hospitalization and had endovascular management of his bullet embolus. CONCLUSION Bullet emboli present a challenging complication of penetrating trauma. We recommend removal of all arterial bullet emboli and those within the pulmonary venous system. In hemodynamically stable patients, we recommend initial attempts of endovascular retrieval followed by open surgical removal. We recommend open removal in cases of hemodynamic instability.

Abstract
The human microbiome is vast and is present in spaces previously thought to be sterile such as the lungs. A healthy microbiome is diverse and functions in an adaptive way to support local as well as organism health and function. Furthermore, a normal microbiome is essential for normal immune system development rendering the array of microbes that live in and on the human body key components of homeostasis. A wide array of clinical conditions and interventions including anesthesia, analgesia, and surgical intervention may derange the human microbiome in a maladaptive fashion with bacterial responses spanning decreased diversity to transformation to a pathogenic phenotype. Herein, we explore the normal microbiome of the skin, gastrointestinal tract, and the lungs as prototype sites to describe the influence of the microbiomes in each of those locations on health, and how care may derange those relations.

Abstract
PURPOSE The aim was to describe the clinical manifestations, complications and long-term outcome of a cohort of Iranian patients with primary immune deficiency (PID). METHOD We retrospectively studied the demographic, clinical and immunological characteristics of the PID patients in a single tertiary centre, from January 1989 to July 2014. The patients were classified according to the International Union of Immunological Societies Expert Committee on PID. RESULTS 98 patients were diagnosed with and followed-up for 15 disorders. The mean age at onset and diagnosis and the diagnostic delay were 8±10, 14.2±13.1 and 6.1±7 years, respectively. Parental consanguinity rate was 57%. Predominantly Antibody Deficiency was the most common diagnosis (n=63), followed by congenital defects of phagocytes (n=16), combined immunodeficiencies (n=12), well defined syndromes (n=4) and defects in innate immunity (n=3). Recurrent sinopulmonary infection was the most common presentation. Active infections were treated appropriately, in addition to prophylactic therapy with IVIG and antimicrobials. Not all the patients were compliant with prophylactic regimens due to cost and unavailability. One SCID patient underwent successful bone marrow transplantation. The total mortality rate was 19% during the follow-up period (7.8±7.6 years). The mean age of living patients at the time of study was 23±11.7 years. CONCLUSIONS Physicians awareness of PID has been rising dramatically in Iran, ensuring an increasing number of patients being diagnosed and treated. More effective treatment services, including health insurance coverage and drug availability are needed to improve the outcome of PID patients.

Abstract
To evaluate the need for congenital rubella syndrome prevention in our national health programme we aimed to determine the rate of anti-rubella positivity in umbilical cord blood samples 8 years after measles-rubella mass vaccination in the Islamic Republic of Iran. In a cross-sectional study we tested umbilical cord blood samples for anti-rubella IgG and IgM by ELISA in 154 deliveries at a university hospital in Tehran. Overall 72.7% of umbilical cord blood samples were positive for anti-rubella lgG and 27.3% were negative. All of the samples were negative for anti-rubella IgM. In the samples with a history of mothers' rubella vaccination, only 87.5% were positive for anti-rubella IgG. The results suggest the need for another mass vaccination for rubella in women of child-bearing age and continuation of routine vaccination of infants, plus consideration of obligatory anti-rubella IgG testing before pregnancy in women who were not vaccinated and vaccination of women before marriage.

Abstract
BACKGROUND Nosocomial rhino sinusitis causes major problems in all Intensive Care Units (ICUs). OBJECTIVE To describe incidence, epidemiologic, clinical manifestations, and microbiologic findings in ICUs admitted cases with nosocomial sinusitis. METHODS#ENTITYSTARTX00026; MATERIALS A prospective, cross sectional study done in Pediatric & Adult ICUs in Rasoul Akram Hospital; Tehran Iran (2007-2008). Para-nasal sinus computed tomography (CT) was performed in all adults with fever of unknown origin (FUO) within 48h of admission and repeated thereafter (4-7 days). Infectious sinusitis was diagnosed by microbiological analysis of sinus fluid aspirates. RESULTS Acute bacterial nosocomial sinusitis proved in 82% (51/ 63) of all cases. Head trauma was the most common cause; (n = 22, 45%) of cases. The results of culture were positive for 45 cases (82%). Of 45 culture positives, 19 yielded Gram negative organisms (41%) and 9 (22%) gave Gram positives (S. aureous, Streptococus spp). The remainders (n = 17, 37%) consisted of mixed aerobic/anaerobic bacteria. Seven cases, were positive in gram staining of sinus drainage and these were positive in culture for S. pneumonia (n = 5), Hemophilus influenza (n = 2). The type of organisms were not related to Glasgow Coma Scale in cases (P = 0.3). CONCLUSION Nosocomial organisms isolated were quite different from community acquired rhino sinusitis cases. Investigation of CT scan and drainage of Para-nasal sinuses would be helpful in undiagnosed FUO cases, especially in traumatic patients. Optimal treatment usually consists of removal of the tubes, mobilizing the patient, and administration the broad-spectrum antibiotics.

Abstract
In a cross-sectional study in a hospital in Tehran in 2006-08 the QuantiFERON-TB interferon-gamma release assay (QTB) was compared with the tuberculin skin test (TST) in 59 young people (aged < 20 years) with close contact with immunocompetent cases of proven pulmonary tuberculosis. After 1 year follow-up 10 subjects had progressed to tuberculosis disease and received treatment; TSTwas positive in 30% and QTB in 100%. Of the 49 non-progressive subjects, TST was positive in 10.4% and QTB in 16.3%. The agreement between TST and QTB assay in non-progressive subjects was poor (K = 0.43). False positive and false negative rates for TST were 40.0% and 9.3% respectively; positive and predictive values were 60.0% and 90.7%. We suggest adding the interferon assay to the skin test in the decision to perform chest X-ray or to start chemoprophylaxis at least in younger subjects (aged < 20 years).

Abstract
OBJECTIVE Sensorineural hearing loss (SNHL) can follow congenital toxoplasmosis. Treatment in the first year of life is associated with diminished occurrence of this sequel. In various parts of Iran, the prevalence of antibodies to Toxoplasma gondii ranges from 24% to 57.7%. We evaluate the possible role of Toxoplasma gondii infection on the occurrence of SNHL in children. DESIGN AND SETTING This case-control study was performed in a tertiary care center in Tehran between 2002 and 2003. This study was carried out based on diagnostic parameters of the American Academy of Otolaryngology criteria for SNHL and a healthy control group. MAIN OUTCOME MEASURES We compared the specific Toxoplasma gondii antibodies (IgM & IgG) measured by ELISA in 95 blood samples of infants with SNHL and 63 healthy matched infants. RESULTS Acute (IgM) and previous (IgG) immunity to Toxoplasma gondii was found in 12 and 21.2% of SNHL children, respectively. Most cases with previous infections (IgG positive) were children aged less than 1 year old (i.e. maternal immunity), but acute infection (IgM positive) was higher in 3-5 year old age group. Acute infection (IgM) was significantly more frequent in the SNHL group, and previous immunity was higher in the controls (CI 95%, P-value = 0.01; 0.01). CONCLUSION With respect to seropositive children, as we were unable to differentiate congenital from acquired cases, we recommend prevention of congenital toxoplasmosis by treatment of Toxoplasma infection in pregnant women and treatment of acquired Toxoplasma gondii infection after birth to minimise the risk of SNHL in children.
