Anogenital HSV in Children: Should Providers Be Concerned for Sexual Abuse?

OBJECTIVE: Anogenital herpes simplex virus (HSV) is most commonly acquired via sexual transmission, although other nonsexual modes of transmission have been proposed. When a child presents with a first-time outbreak of anogenital HSV, providers must consider sexual abuse. There are currently no evidence-based consensus guidelines to inform management of these patients. The purpose of this study was to describe how child abuse pediatricians (CAPs) evaluate children with anogenital HSV infection and determine whether any consistent practice patterns are followed. PARTICIPANTS AND SETTING: The patients included in this study were children between the ages of 0 and 12 years with a first-time outbreak of anogenital HSV who were medically evaluated by a CAP. METHODS: Patient charts were retroactively reviewed for the period of January 1 2004 to May 1 2020. RESULTS: Twenty-two cases were referred for evaluation by a CAP in the chosen time frame. Fifteen were seen in person. Ten of these patients were interviewed, 15 had an anogenital exam with colposcopy, and 14 were tested for at least one other sexually transmitted infection. A diagnosis of sexual abuse was made for 1 patient. CONCLUSION: This study demonstrates that although nonsexual transmission of anogenital HSV may be possible, providers must still consider sexual abuse. Children with a first-time outbreak of anogenital HSV should have a comprehensive evaluation for sexual abuse, including interview, physical exam, and testing for sexually transmitted infections. Evidence-based concerns for sexual abuse should be reported to child protective services.

Impact of time to surgery on mortality in hypotensive patients with noncompressible torso hemorrhage: An AAST multicenter, prospective study.

BACKGROUND: Death from noncompressible torso hemorrhage (NCTH) may be preventable with improved prehospital care and shorter in-hospital times to hemorrhage control. We hypothesized that shorter times to surgical intervention for hemorrhage control would decrease mortality in hypotensive patients with NCTH. METHODS: This was an AAST-sponsored multicenter, prospective analysis of hypotensive patients aged 15+ years who presented with NCTH from May 2018 to December 2020. Hypotension was defined as an initial systolic blood pressure (SBP) ≤ 90 mm Hg. Primary outcomes of interest were time to surgical intervention and in-hospital mortality. RESULTS: There were 242 hypotensive patients, of which 48 died (19.8%). Nonsurvivors had higher mean age (47.3 vs. 38.8; p = 0.02), higher mean New Injury Severity Score (38 vs. 29; p < 0.001), lower admit systolic blood pressure (68 vs. 79 mm Hg; p < 0.01), higher incidence of vascular injury (41.7% vs. 21.1%; p = 0.02), and shorter median (interquartile range, 25-75) time from injury to operating room start (74 minutes [48-98 minutes] vs. 88 minutes [61-128 minutes]; p = 0.03) than did survivors. Multivariable Cox regression showed shorter time from emergency department arrival to operating room start was not associated with improved survival (p = 0.04). CONCLUSION: Patients who died arrived to a trauma center in a similar time frame as did survivors but presented in greater physiological distress and had significantly shorter times to surgical hemorrhage intervention than did survivors. This suggests that even expediting a critically ill patient through the current trauma system is not sufficient time to save lives from NCTH. Civilian prehospital advance resuscitative care starting from the patient first contact needs special consideration. LEVEL OF EVIDENCE: Prognostic/Epidemiologic, Level III.

An analysis of police transport in an Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS: This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS: Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION: Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

Police transport of firearm-injured patients-more often and more injured.

BACKGROUND: Police transport (PT) of penetrating trauma patients decreases the time between injury and trauma center arrival. Our study objective was to characterize trends in the rate of PT and its impact on mortality. We hypothesized that PT is increasing and that these patients are more injured. METHODS: We conducted a single-center, retrospective cohort study of adult (≥18 years) patients presenting with gunshot wounds (GSWs) to a level 1 center from 2012 to 2018. Patients transported by police or ambulance (emergency medical service [EMS]) were included. The association between mode of transport (PT vs. EMS) and mortality was evaluated using χ2, t tests, Mann-Whitney U tests, and logistic regression. RESULTS: Of 2,007 patients, there were 1,357 PT patients and 650 EMS patients. Overall in-hospital mortality was 23.7%. The rate of GSW patients arriving by PT increased from 48.9% to 78.5% over the study period (p < 0.001). Compared with EMS patients, PT patients were sicker on presentation with lower initial systolic blood pressure (98 vs. 110, p < 0.001), higher Injury Severity Score (median [interquartile range], 10 [2-75] vs. 9 [1-17]; p < 0.001) and more bullet wounds (3.5 vs. 2.9, p < 0.001). Police-transported patients more frequently underwent resuscitative thoracotomy (19.2% vs. 10.0%, p < 0.001) and immediate surgical exploration (31.3% vs. 22.6%, p < 0.001). There was no difference in adjusted in-hospital mortality between transport groups. Of patients surviving to discharge, PT patients had higher Injury Severity Score (9.6 vs. 8.3, p = 0.004) and lower systolic blood pressure on arrival (126 vs. 130, p = 0.013) than EMS patients. CONCLUSION: Police transport of GSW patients is increasing at our urban level 1 center. Compared with EMS patients, PT patients are more severely injured but have similar in-hospital mortality. Further study is necessary to understand the impact of PT on outcomes in specific subsets in penetrating trauma patients. LEVEL OF EVIDENCE: Epidemiological, level III.

An Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Prehospital procedures (PHP) by emergency medical services (EMS) are performed regularly in penetrating trauma patients despite previous studies demonstrating no benefit. We sought to examine the influence of PHPs on outcomes in penetrating trauma patients in urban locations where transport to trauma center is not prolonged. We hypothesized that patients without PHPs would have better outcomes than those undergoing PHP. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored, multicenter, prospective, observational trial of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. The impact of PHPs and transport mechanism on in-hospital mortality were examined. RESULTS: Of 2,284 patients included, 1,386 (60.7%) underwent PHP. The patients were primarily Black (n = 1,527, 66.9%) males (n = 1,986, 87.5%) injured by gunshot wound (n = 1,510, 66.0%) with 34.1% (n = 726) having New Injury Severity Score of ≥16. A total of 1,427 patients (62.5%) were transported by Advanced Life Support EMS, 17.2% (n = 392) by private vehicle, 13.7% (n = 312) by police, and 6.7% (n = 153) by Basic Life Support EMS. Of the PHP patients, 69.1% received PHP on scene, 59.9% received PHP in route, and 29.0% received PHP both on scene and in route. Initial scene vitals differed between groups, but initial emergency department vitals did not. Receipt of ≥1 PHP increased mortality odds (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.01-1.83; p = 0.04). Logistic regression showed increased mortality with each PHP, whether on scene or during transport. Subset analysis of specific PHP revealed that intubation (OR, 10.76; 95% CI, 4.02-28.78; p < 0.001), C-spine immobilization (OR, 5.80; 95% CI, 1.85-18.26; p < 0.01), and pleural decompression (OR, 3.70; 95% CI, 1.33-10.28; p = 0.01) had the highest odds of mortality after adjusting for multiple variables. CONCLUSION: Prehospital procedures in penetrating trauma patients impart no survival advantage and may be harmful in urban settings, even when performed during transport. Therefore, PHP should be forgone in lieu of immediate transport to improve patient outcomes. LEVEL OF EVIDENCE: Prognostic, level III.

Nanoparticle Encapsulation of Synergistic Immune Agonists Enables Systemic Codelivery to Tumor Sites and IFNß-Driven Antitumor Immunity.

Effective cancer immunotherapy depends on the robust activation of tumor-specific antigen-presenting cells (APC). Immune agonists encapsulated within nanoparticles (NP) can be delivered to tumor sites to generate powerful antitumor immune responses with minimal off-target dissemination. Systemic delivery enables widespread access to the microvasculature and draining to the APC-rich perivasculature. We developed an immuno-nanoparticle (immuno-NP) coloaded with cyclic diguanylate monophosphate, an agonist of the stimulator of interferon genes pathway, and monophosphoryl lipid A, and a Toll-like receptor 4 agonist, which synergize to produce high levels of type I IFNß. Using a murine model of metastatic triple-negative breast cancer, systemic delivery of these immuno-NPs resulted in significant therapeutic outcomes due to extensive upregulation of APCs and natural killer cells in the blood and tumor compared with control treatments. These results indicate that NPs can facilitate systemic delivery of multiple immune-potentiating cargoes for effective APC-driven local and systemic antitumor immunity. SIGNIFICANCE: Systemic administration of an immuno-nanoparticle in a murine breast tumor model drives a robust tumor site-specific APC response by delivering two synergistic immune-potentiating molecules, highlighting the potential of nanoparticles for immunotherapy.

HIV and HCV screening among trauma patients.

The purpose of this study was to develop a hepatitis C virus (HCV) and HIV screening program for patients evaluated by the trauma service and link to care. Patients were offered screening for HCV antibody and HIV. Demographics were collected on gender, race, age, and history of intravenous drug use. A navigator connected patients to treatment. In total, 1160 trauma patients were screened for HCV and/or HIV. There were 162 (14%) patients with HCV antibodies. Patients who inject drugs comprised 39.5% (64) of the HCV antibody positive group. Forty-six (68.7%) patients received linkage to care services and 55 (34%) patients were actively engaged in treatment. There were 155 (10.5%) of all eligible patients screened for HIV. Twenty-one (13.5%) patients were living with HIV (PLWH) and there were two (1.3%) new HIV infections. All new PLWH were linked to care and a total of 14 (73.7%) PLWH were on antiretroviral therapy. This is the first HCV and HIV screening and linkage to care program of trauma surgery patients. In this interim program evaluation, we found high prevalence of HCV antibody and HIV prevalence and high linkage to care rates. Trauma service HCV and HIV screening is an opportunity to diagnose, link, and re-engage a vulnerable population.

Malignant Phyllodes Tumors of the Breast: Association Between Race, Clinical Features, and Outcomes.

BACKGROUND: We sought to investigate associations between race, clinical characteristics, and outcomes among patients with malignant phyllodes of the breast. METHODS: Malignant phyllodes cases were identified using Surveillance Epidemiology and End Results database. We used chi-square tests to compare characteristics between racial groups and multinomial logistic regression to calculate relative risk ratios (RRR) and 95% confidence intervals (CI) comparing the likelihood of having particular characteristics by race. Survival analyses included Cox regression and Kaplan-Meier functions. RESULTS: Among 1202 patients included, mean age was 51.7 y and 55.2% were white. Compared to whites, blacks were younger (mean age 45.7 versus 55.1 y; P < 0.001), and more likely to have tumors 51-100 mm (RRR = 1.91; 95% CI: 1.20-3.05) and tumors > 100 mm (RRR = 2.52; 95% CI: 1.56-4.05) than tumors ≤ 50 mm in size. Compared to whites, Hispanics were younger (mean age 46.7 versus 55.1 y; P < 0.001), and more likely to have tumors 51-100 mm (RRR = 1.46; 95% CI: 1.01-2.11) than tumors ≤ 50 mm in size. Asians were more likely to have tumors 51-100 mm (RRR = 1.52; 95% CI: 1.01-2.30) and tumors > 100 mm (RRR = 1.61; 95% CI: 1.03-2.52) than tumors ≤ 50 mm in size, and more likely to have tumors that extended beyond the breast tissue (RRR = 1.87; 95% CI: 1.05-3.31), compared to whites. Survival was similar for blacks (HR = 1.48; 95% CI: 0.80-2.76), Hispanics (HR = 1.02; 95% CI: 0.54-1.93), and Asians (HR = 1.13; 95% CI: 0.63-2.01) compared to whites. CONCLUSIONS: Further research into factors contributing to extensive disease at presentation among minorities is warranted.

Regional diagnostic rates, treatments, and outcomes among patients with invasive ductal carcinoma.

BACKGROUND: The association between regional breast cancer diagnostic rates, treatments, and outcomes is unclear. We sought to investigate the management and survival of women with invasive ductal carcinoma (IDC) from geographic regions with variable rates of diagnosis. METHODS: Data on women diagnosed with IDC years 2009-2010 were obtained from the Surveillance, Epidemiology, and End Results database. Patients were divided into quartiles based on the IDC diagnostic rate within their county of residence. Chi-square and one-way analysis of variance (ANOVA) analyses tested the association between patient and clinical characteristics and the diagnostic rate quartiles. Cox regression analyses compared survival between the quartiles. RESULTS: Among the 83,375 patients included, the mean age was 60.8 y and 70.9% were white. Patients residing in counties with the highest diagnostic rates were more frequently white, employed, educated, and wealthier and more often received adjuvant radiation following both partial mastectomy for localized disease and complete mastectomy for advanced disease compared to patients in counties with the lowest diagnostic rates. The highest diagnostic rate quartile had 10% decreased odds of death compared to the lower quartile (hazard ratio: 0.897; 95% confidence interval: 0.832-0.966). However, after adjustment for socioeconomic variables, survival was comparable (hazard ratio: 0.916; 95% confidence interval: 0.835-1.003). CONCLUSIONS: Regional variation in IDC diagnostic rates is associated with differences in socioeconomic status, grade, stage, and treatment. Patients from regions with the highest rates of diagnosis may have improved access to evidence-based care and resultant superior survival. Enhancing access to care may improve outcomes of patients residing in regions where breast cancer is diagnosed less frequently.

Normal Anal Examination After Penetration: A Case Report.

BACKGROUND: Physical findings are rare after anal penetration. Furthermore, children delay in disclosing or are reticent to discuss penetration. CASE REPORT: A 12-year-old boy presented to medical care multiple times over a several-week period complaining of abdominal pain, bloody diarrhea, and poor appetite. On colonoscopy, he was found to have a cylindrical foreign body (measuring 7 cm tall and 7 cm in diameter) in his rectum, which had been present for at least 2 weeks. He initially denied knowing how the object got into his rectum and later stated that he inserted it himself out of curiosity. One week after the object was removed, follow-up examination using video colposcopy revealed a completely normal anal examination; the patient had a normal anal examination despite known anal penetration and removal of the object. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Children can have a normal anal examination despite anal penetration, and do not always disclose anal penetration. The aforementioned concepts can be applied to situations related to child sexual abuse in the emergency department, where physical examinations are frequently normal and children delay in disclosing the abuse. When there is concern for sexual abuse, even in the absence of a disclosure or examination findings, patients should be referred for a child abuse pediatrics evaluation if available.

Optimizing performance through stress training - An educational strategy for surgical residents.

BACKGROUND: Stress management programs improve efficacy in aviation, military, and professional sports; however, similar educational strategies have not been adopted in surgical training. We have evaluated the effectiveness of a stress management program for surgical residents. METHODS: From 2011 to 2016, 137 surgical residents participated in a prospective, blinded study. The intervention group (n = 65) underwent training in self-awareness, focus, relaxation, positive self-talk, visualization, and team building. All participants subsequently completed a high-stress trauma simulation, requiring diagnosis and management of a life-threatening problem. Study endpoints included measures of procedural efficiency, and physiologic and subjective measurements of anxiety. RESULTS: Residents with stress training came to an accurate diagnosis 21% faster than controls (mean diagnosis time: 2.2 vs. 2.8 min; p = 0.04), and performed with greater technical accuracy (mean OSAT scores: 9.4 vs. 8.9; p = 0.03). Both cohorts exhibited similar physiologic and subjective anxiety metrics after simulation. CONCLUSIONS: Stress management education may enhance technical performance in surgical trainees during simulation. This underscores the need for early, comprehensive stress training in surgical residency.

Global surgical electives in residency: The impact on training and future practice.

BACKGROUND: The purpose of this study was to evaluate perceptions regarding the value of global surgical electives (GSEs) and pursuit of a career in global surgery amongst residents and surgeons. METHODS: We sent an anonymous questionnaire to all current and former surgical residents of our tertiary-care, university-based institution from the years 2000-2013. Questions addressed the experience and value of practicing surgery in low or middle income countries (LMIC) in residency and as a career. RESULTS: Twenty-three (40%) graduates (G) and 36 (84%) surgical residents (R) completed the survey. Thirteen residents (36%) and 13 (52%) graduates had delivered surgical care in a LMIC. Respondents stated that their experience positively impacted patient care (G = 80% vs R = 75%) and learning (G = 75% vs R = 90%). Of the 4 graduates still working in a LMIC, the majority (75%) were providing less than 2 months of care. Logistical reasons and family obligations were the most common barriers (n = 13). CONCLUSION: Few graduates are able to incorporate global surgery into their practice despite interest. For enduring participation, logistical and family support is needed.

American College of Surgeons NSQIP Risk Calculator Accuracy for Emergent and Elective Colorectal Operations.

BACKGROUND: The American College of Surgeons NSQIP has developed a risk calculator (RC) to assist patients and surgeons with difficult decisions. The aim of this analysis was to determine the accuracy of the RC in patients undergoing elective and emergent colorectal operations. STUDY DESIGN: From January 2013 through December 2015, seventy-five patients undergoing emergent colorectal operations were paired by date with 75 patients having elective colorectal operations. Patient data were entered into the RC. Actual postoperative outcomes, derived from NSQIP data, were compared with those predicted by the RC. RESULTS: Emergent and elective patients differed (p < 0.05) with respect to age, functional status, American Society of Anesthesiologists class, steroid use, wound class, COPD, and chronic renal insufficiency. The RC accurately predicted outcomes in elective patients. Outcomes were significantly worse (p < 0.05) after the emergent operations. In emergent cases, the RC underestimated serious complications and length of stay and overestimated discharge to a skilled nursing facility (all p < 0.05). CONCLUSIONS: The American College of Surgeons NSQIP RC accurately predicts outcomes for elective colorectal operations. Predicted and actual outcomes are significantly better in patients undergoing elective colon operations compared with those undergoing emergent procedures. The RC should be used with caution in emergent cases, as it has the potential to underestimate serious complications and length of stay, and overestimate discharge to skilled nursing facility. Refinement of the tool to include procedure complexity and diagnosis terms might improve its accuracy in emergent cases.

An Informed Consent Program Enhances Surgery Resident Education.

OBJECTIVE: First-year residents often obtain informed consent from patients. However, they typically receive no formal training in this area before residency. We wished to determine whether an educational program would improve residents' comfort with this process. DESIGN: Our institution created an informed consent educational program, which included a didactic component, a role-play about informed consent, and a simulation exercise using standardized patients. Residents completed surveys before and after the intervention, and responses to survey questions were compared using the signed-rank test. SETTING: This study took place at Temple University Hospital, a tertiary care institution in Philadelphia, PA. PARTICIPANTS: First-year surgery and emergency medicine residents at Temple University Hospital in 2014 participated in this study. Thirty-two residents completed the preintervention survey and 27 residents completed the educational program and postintervention survey. RESULTS: Only 37.5% had ever received formal training in informed consent before residency. After participating in the educational program, residents were significantly more confident that they could correctly describe the process of informed consent, properly fill out a procedure consent form, and properly obtain informed consent from a patient. Their comfort level in obtaining informed consent significantly increased. They found the educational program to be very effective in improving their knowledge and comfort level in obtaining informed consent. In all, 100% (N = 27) of residents said they would recommend the use of the program with other first-year residents. CONCLUSIONS: Residents became more confident in their ability to obtain informed consent after participating in an educational program that included didactic, role-play, and patient simulation elements.

Acute right heart failure after hemorrhagic shock and trauma pneumonectomy-a management approach: A blinded randomized controlled animal trial using inhaled nitric oxide.

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. Inhaled nitric oxide (iNO) lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep. Sheep received lung protective ventilatory support and were instrumented to serially obtain measurements of hemodynamics, gas exchange, and blood chemistry. Heart function was assessed with echocardiography. After randomization to study gas of iNO 20 ppm (n = 9) or nitrogen as placebo (n = 9), baseline measurements were obtained. Hemorrhagic shock was initiated by exsanguination to a target of 50% of the baseline mean arterial pressure. The resuscitation phase was initiated, consisting of simultaneous left pulmonary hilum ligation, via median sternotomy, infusion of autologous blood and initiation of study gas. Animals were monitored for 4 hours. RESULTS: All animals had an initial increase in PVR. PVR remained elevated with placebo; with iNO, PVR decreased to baseline. Echo showed improved RV function in the iNO group while it remained impaired in the placebo group. After an initial increase in shunt and lactate and decrease in SvO2, all returned toward baseline in the iNO group but remained abnormal in the placebo group. CONCLUSION: These data indicate that by decreasing PVR, iNO decreased RV afterload, preserved RV and LV function, and tissue oxygenation in this hemorrhagic shock and pneumonectomy model. This suggests that iNO may be a useful clinical adjunct to mitigate right heart failure and improve survival when trauma pneumonectomy is required.

Assuring survival of safety-net surgical patients.

BACKGROUND: Survival of surgical inpatients is a key quality metric. Patient, surgeon, and system factors all contribute to inpatient mortality, and sophisticated risk adjustment is required to assess outcomes. When the mortality of general surgery patients was determined to be high at a safety-net hospital, a comprehensive approach was undertaken to improve patient survival. METHODS: General surgical service line mortality was measured in the database of the University HealthSystem Consortium from January 2013 through June 2015. Ten best practices were implemented sequentially to decrease observed and/or increase expected mortality. University HealthSystem Consortium mortality rank, observed, expected, and observed/expected index as well as early deaths were compared with control charts for 30 months. RESULTS: University HealthSystem Consortium general surgery mortality improved from the bottom decile to the top quartile, while Case Mix Index increased from 2.48 to 2.82 (P < .05). Observed mortality decreased from 3.39 to 2.35%. Expected mortality increased from 1.40 to 2.73% (P < .05). The observed/expected mortality index decreased from 2.43 to 0.86 (P < .05). Early deaths decreased from 0.52 to 0% (P < .05). CONCLUSION: Risk-adjusted mortality and early deaths decreased significantly over 30 months in general surgery patients. Systematic implementation of quality best practices was associated with improved survival of general surgery patients at a safety-net medical center.
