BACKGROUND: A congenital lung malformation (CLM) that is diagnosed on prenatal ultrasound exam may subsequently become undetectable on later scans, a "vanishing" CLM. OBJECTIVE: The purpose of our study is to characterize the prenatal natural history and postnatal outcomes of "vanishing" lesions treated at our institution. METHODS: We performed a retrospective chart review of 107 patients diagnosed prenatally with CLM at our institution. Comparisons were made using Kruskal-Wallis or t-test for continuous variables and Fisher's exact test or Chi-Square test for categorical variables. Multivariable analysis using logistic regression was performed. RESULTS: Of the 104 patients, 59 (56.7%) had lesions that became sonographically undetectable on serial ultrasound scans. Patients with lesions that vanished prenatally tended to need less Neonatal Intensive Care Unit (NICU) admission at birth (persistent CLM: 54.8%vs vanished CLM: 28.8%), decreased need for supplemental O2 at birth (persistent CLM: 31.0%vs vanished CLM: 11.9%), and decreased delay in feeds (persistent CLM: 26.2%vs vanished CLM: 8.5%) compared to those with persistent CLM. After multivariate analysis controlling for maternal steroid administration and sex, admission to NICU maintained a slight statistical significance, with patients in the vanishing CLM group 2.5 times less likely to be admitted to the NICU. None of our patients whose lesions vanished prenatally required mechanical ventilation. Eighty-six patients underwent postnatal computed tomography (CT) chest. Only 2 patients had lesions that regressed on postnatal CT. CONCLUSION: Lesions that vanish on prenatal imaging may be associated with improved clinical outcomes. The rate of true regression at our institution was as low as 2.3%. [ABSTRACT FROM AUTHOR]

Background: Institutions lack consensus on the management of patients with congenital diaphragmatic hernia (CDH) who are repaired on extracorporeal membrane oxygenation (ECMO). Our study aimed to evaluate risk factors associated with bleeding complications in patients with CDH repaired on ECMO., Methods: A single-institution retrospective review evaluated all patients with CDH who underwent on-ECMO repair between January 2005 and December 2023. A significant bleeding complication post-repair was defined as bleeding necessitating re-operation. The association between preoperative factors and bleeding complications was evaluated., Results: Forty-six patients were included. Bleeding complications developed in 11/46 (24%) patients. Birthweight (2.5 vs. 3.2 kg, p = 0.02), platelet count <100/mm 3 (64% vs. 29%, p = 0.04), elevated blood urea nitrogen (BUN; 24.5 vs. 17.5 mg/dL, p = 0.05), and older age at repair (8 vs. 5 days, p = 0.04) were associated with bleeding. In univariate analysis, patients with platelets under 100/mm 3 were more likely to develop a bleeding complication (OR = 4.4, p = 0.04). Patients who experienced a significant bleeding event experienced increased ECMO days (12 vs. 7 days, p < 0.01), ventilator days (31 vs. 18 days, p < 0.05), and lower survival to discharge (36% vs. 74%, p = 0.03)., Conclusion: Among CDH patients undergoing repair on ECMO, those with lower birth weight, platelet counts under 100/mm 3 , elevated BUN, and older age at repair had an increased risk of a significant bleeding complication, resulting in more ECMO and ventilator days and higher mortality. Patients undergoing on-ECMO repair should have platelet count transfused to greater than 100/mm 3 . Patients at high risk for bleeding may benefit from early repair on ECMO., Level of Evidence: Level III., Competing Interests: Conflicts of interest None., (Copyright © 2024 Elsevier Inc.

Background: Small bowel obstruction (SBO) is a known complication following congenital diaphragmatic hernia (CDH) repair, resulting in significant morbidity and potential mortality. Our study aims to evaluate the incidence and risk factors for SBO following CDH repair., Methods: A single-institution retrospective review evaluated all CDH births between January 2010 and September 2022 (n = 120). Risk factors for SBO were analyzed, including operative approach, type of repair, need for extracorporeal membrane oxygenation (ECMO), and additional abdominal surgeries (gastrostomy tube and fundoplication)., Results: 120 patients were included. 16 (13%) patients developed an SBO, of which 94% were due to adhesive bands. The median time to SBO was 7.5 months. 15/16 (94%) patients required operative intervention. Need for ECMO ( P < 0.01), prior gastrostomy tube ( P < 0.01), and prior fundoplication ( P < 0.01) were associated with an increased risk of SBO, as were longer time to initial CDH repair (6 days vs 3 days; P < 0.01) and longer length of initial hospitalization (63 days vs 29 days; P = 0.01)., Discussion: Neonates with increased acuity of illness (ie, those requiring ECMO, additional abdominal operations, longer time to repair, and longer initial hospitalizations) appear to have an increased risk of developing adhesive SBO after CDH repair. More than 90% of patients who developed SBO required surgery., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Fetal head and neck masses can result in critical airway obstruction. Our study aimed to evaluate prenatal factors associated with the decision for a definitive airway, including ex-utero intrapartum treatment (EXIT), at birth among at-risk fetuses., Methods: A single-institution retrospective review evaluated all fetal head and neck masses prenatally diagnosed from 2005 to 2023. The primary outcome was the decision for a definitive airway at birth, including intubation, tracheostomy, or EXIT., Results: Thirty four patients were included, with 23 deliveries occurring at our institution. 8/23 (35%) patients received a definitive airway at birth, six underwent an EXIT procedure, and two required intubation only. Patients who received a definitive airway had higher rates of polyhydramnios (50% vs. 7%, p = 0.03), tracheal narrowing on ultrasound (US) (50% vs. 0%, p = 0.01), tracheal displacement on US (63% vs. 0%, p < 0.01), abnormal fetal breathing on US (50% vs. 0%, p = 0.01), tracheal narrowing or displacement on magnetic resonance imaging (MRI) (75% vs. 7%, p < 0.01), and larger mass maximum diameter (7.9 vs. 4.3 cm, p = 0.02). In our series, 100% of patients with polyhydramnios, tracheal narrowing or displacement on either US or MRI, and abnormal fetal breathing on US received a definitive airway at birth., Conclusion: Prenatal findings of tracheal narrowing or displacement, polyhydramnios, and abnormal fetal breathing are strongly associated with the decision for a definitive airway at birth and warrant mobilization of appropriate resources., (© 2024 John Wiley & Sons Ltd.)

Background: Bronchogenic cysts result from a congenital anomalous budding of the tracheobronchial tree. Resection is usually recommended to avoid complications. Mediastinal bronchogenic cysts present a unique challenge due to their proximity to vital structures. The purpose of this study is to review our experience with mediastinal bronchogenic cysts. Methods: A single-institution retrospective review evaluated all mediastinal bronchogenic cyst excisions between January 2012 and November 2022. Patient demographics were assessed, including age at diagnosis, presenting symptoms, imaging workup, and cyst characteristics. Operative approach, complications, and surgical pathology were reported. Results: Five patients were identified. Age at diagnosis ranged from 18 to 27 months. No patient was diagnosed prenatally. All patients had symptoms at the time of diagnosis, including cough, wheezing, and respiratory distress. Three cysts were paratracheal, and two were paraesophageal. Age at surgery ranged from 26 to 30 months. All bronchogenic cysts were successfully resected thoracoscopically. Individual technical challenges included narrowing of the mainstem bronchus preventing lung isolation, significant mediastinal inflammation, the necessity for cyst evacuation to delineate the extent of the cyst, adherence of cyst wall to bronchus or trachea requiring cold dissection, and a stalk of tissue with an intimate connection to the carina that was amputated. No intraoperative or postoperative complication occurred. Surgical pathology was consistent with a bronchogenic cyst in all cases. Median length of hospital stay was two days. Conclusion: Thoracoscopy is a safe and effective procedure for mediastinal bronchogenic cyst excision in children. Certain technical maneuvers are highlighted, which may facilitate resection.

Introduction: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases., Methods: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine. A three-round Delphi process was conducted via an online survey, with each round being followed by a live video conference. Experts agreed or disagreed with each aspect of the proposed fluid management algorithm on a five-level Likert scale. The group opinion level defined an algorithm parameter's acceptance or rejection with greater than 75% agreement resulting in acceptance and greater than 50% disagreement resulting in rejection. The remaining were discussed and re-presented in the next round., Results: Fourteen experts from five Level 1 pediatric trauma centers representing three subspecialties were included. Responses were received from 13/14 participants (93%). In round 1, 64% of the parameters were accepted, while the remaining 36% were discussed and re-presented. In round 2, 90% of the parameters were accepted. Following round 3, there was 100% acceptance by all the experts on the revised and final version of the algorithm., Conclusions: We present a validated algorithm for intavenous fluid management in pediatric trauma patients that focuses on the de-escalation of fluids. Focusing on this time point of fluid therapy will help minimize iatrogenic complications of crystalloid fluids within this patient population., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Objective: The aim of this article was to evaluate high-frequency positive pressure ventilation (HFPPV) compared with high-frequency oscillatory ventilation (HFOV) as a rescue ventilation strategy for patients with congenital diaphragmatic hernia (CDH). HFPPV is a pressure-controlled conventional ventilation method utilizing high respiratory rate and low positive end-expiratory pressure., Study Design: Seventy-seven patients diagnosed with CDH from January 2005 to September 2019 who were treated with stepwise progression from HFPPV to HFOV versus only HFOV were included. Fisher's exact test and the Kruskal-Wallis test were used to compare outcomes., Results: Patients treated with HFPPV + HFOV had higher survival to discharge (80 vs. 50%, p  = 0.007) and to surgical intervention (95.6 vs. 68.8%, p  = 0.003), with average age at repair 2 days earlier ( p  = 0.004). Need for extracorporeal membrane oxygenation ( p  = 0.490), inhaled nitric oxide ( p  = 0.585), supplemental oxygen ( p  = 0.341), and pulmonary hypertension medications ( p  = 0.381) were similar., Conclusion: In CDH patients who fail respiratory support with conventional ventilation, HFPPV may be used as an intermediary mode of rescue ventilation prior to HFOV without adverse effects., Key Points: · HFPPV may be used as an intermediary mode of rescue ventilation prior to HFOV without adverse effect.. · HFPPV is more widely available and can mitigate the limitations faced when using HFOV.. · HFPPV allows for intra- or interhospital transfer of neonates with CDH.., Competing Interests: None declared., (Thieme.

Background: Congenital lung malformations (CLM) are rare developmental anomalies of the fetal lung with a minority of patients exhibiting symptoms around the time of birth. Although ultrasound remains the gold standard, fetal MRI has recently been incorporated as an adjunct imaging modality in the workup and prenatal counseling of patients with CLM as it is thought to more accurately delineate lesion boundaries and diagnose lesion type. We evaluate what prenatal variables correlate with postnatal respiratory symptoms., Methods: We performed a retrospective review of patients with prenatal diagnosis of CLM treated at our institution between 2006-2020. Fetal ultrasound and magnetic resonance imaging (MRI) parameters including maximal congenital pulmonary airway malformation volume ratio (CVR), absolute cyst volume, and observed to expected normal fetal lung volume (O/E NFLV) were correlated with outcomes including postnatal respiratory symptoms, need for supplementary oxygen or mechanical ventilation, delay in tolerating full feeds, resection in the neonatal period., Results: Our study included 111 patients, all of whom underwent fetal ultrasound with 64 patients additionally undergoing fetal MRI. Postnatal respiratory symptoms were noted in 22.5% of patients, 19.8% required supplemental oxygen, 2.7% mechanical ventilation and two patients requiring urgent resection. Ultrasound parameters including absolute cyst volume and maximal CVR correlated with need for mechanical ventilation (p=0.034 and p=0.024, respectively) and for urgent resection (p=0.018 and p=0.023, respectively) and had a marginal association with postnatal respiratory symptoms (p=0.050 and p=0.052). Absolute cyst volume became associated with postnatal respiratory symptoms (p=0.017) after multivariable analysis controlling for maternal steroid administration and gestational age. O/E NFLV did not correlate with perinatal outcomes., Conclusion: We have found that ultrasound-based measurements correlate with postnatal respiratory symptoms, while MRI derived O/E NFLV does not. Further studies are needed to elucidate the role of MRI in the prenatal workup of congenital lung malformations., Type of Study: Study of Diagnostic Test., Level of Evidence: Level I., (Copyright © 2022 Elsevier Inc.

Achieving postpyloric feeding access is a clinical challenge faced by the pediatric gastroenterologist in everyday practice. Currently, there is limited literature published on the topic. This article provides a practical summary of the literature on the different methods utilized to achieve postpyloric feeding access including bedside, fluoroscopic, endoscopic and surgical options. Indications and complications of these methods are discussed as well as a general approach to infants and children that require intestinal feeding., (Copyright © 2022 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Background: Gastrojejunostomy (GJ) tubes are commonly used to provide postpyloric enteral nutrition in pediatric patients who cannot tolerate gastric feeds. Most techniques depend on a preexisting gastrostomy tube (GT) site to convert to a gastrojejunostomy. Several minimally invasive techniques have been described; however, their risk profile varies widely., Description of the Operative Technique: We present a technique for primary laparoscopic GJ tube placement that minimizes the risk of hollow viscus injury and the use of fluoroscopy through endoscopic assistance., Results: Eleven GJ tubes were placed using this technique in patients ranging from 5 months to 17 years of age and weighing 6.3 to 46.0 kg. Endoscopy through the gastrostomy site allowed direct visualization of wire and tube placement. There were no intraoperative or postoperative complications within 30 days of operation. Use of fluoroscopy was limited with minimal total radiation exposure., Conclusion: The described technique of laparoscopic primary gastrojejunostomy tube placement with endoscopic assistance was associated with a low complication rate and minimal use of fluoroscopy., Level of Evidence: IV., (Copyright © 2020 Elsevier Inc.

Purpose: Congenital diaphragmatic hernia (CDH) is associated with significant mortality and long-term morbidity in some but not all individuals. We hypothesize monogenic factors that cause CDH are likely to have pleiotropic effects and be associated with worse clinical outcomes., Methods: We enrolled and prospectively followed 647 newborns with CDH and performed genomic sequencing on 462 trios to identify de novo variants. We grouped cases into those with and without likely damaging (LD) variants and systematically assessed CDH clinical outcomes between the genetic groups., Results: Complex cases with additional congenital anomalies had higher mortality than isolated cases (P = 8 × 10 -6 ). Isolated cases with LD variants had similar mortality to complex cases and much higher mortality than isolated cases without LD (P = 3 × 10 -3 ). The trend was similar with pulmonary hypertension at 1 month. Cases with LD variants had an estimated 12-17 points lower scores on neurodevelopmental assessments at 2 years compared with cases without LD variants, and this difference is similar in isolated and complex cases., Conclusion: We found that the LD genetic variants are associated with higher mortality, worse pulmonary hypertension, and worse neurodevelopment outcomes compared with non-LD variants. Our results have important implications for prognosis, potential intervention and long-term follow up for children with CDH.

Background: Our understanding of the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on pregnancies and perinatal outcomes is limited. The clinical course of neonates born to women who acquired coronavirus disease 2019 (COVID-19) during their pregnancy has been previously described. However, the course of neonates born with complex congenital malformations during the COVID-19 pandemic is not known., Methods: We report a case series of seven neonates with congenital heart and lung malformations born to women who tested positive for SARS-CoV-2 during their pregnancy at a single academic medical center in New York City., Results: Six infants had congenital heart disease and one was diagnosed with congenital diaphragmatic hernia. In all seven infants, the clinical course was as expected for the congenital lesion. None of the seven exhibited symptoms generally associated with COVID-19. None of the infants in our case series tested positive by nasopharyngeal test for SARS-CoV-2 at 24 hours of life and at multiple points during their hospital course., Conclusions: In this case series, maternal infection with SARS-CoV-2 during pregnancy did not result in adverse outcomes in neonates with complex heart or lung malformations. Neither vertical nor horizontal transmission of SARS-CoV-2 was noted.

Objective: During the COVID-19 pandemic, experience-based guidelines are needed in the pediatric population in order to deliver high quality care in a new way that keeps patients and healthcare workers safe and maximizes hospital resource utilization., Background: The COVID-19 pandemic has created an unprecedented strain on national health care resources, particularly in New York City, the epicenter of the outbreak in the United States. Prudent allocation of surgical resources during the pandemic quickly became essential, and there is an unprecedented need to weigh the risks of operating versus delaying intervention in our pediatric patients., Methods: Here we describe our experience in surgical decision-making in the pediatric surgical population at Morgan Stanley Children's Hospital of New York-Presbyterian (MSCHONY), which has served as a major urban catchment area for COVID-19 positive pediatric patients. We describe how we have adjusted our current treatment of multiple facets of pediatric surgery including oncology, trauma, minimally invasive procedures, and extracorporeal membrane oxygenation (ECMO)., Conclusions: Our pediatric surgery department had to creatively and expeditiously adjust our protocols, guidelines, and workforce to not only serve our pediatric population but merge ourselves with our adult hospital system during the COVID pandemic., Type of Study: Clinical research paper LEVEL OF EVIDENCE: Level V., (Copyright © 2020 Elsevier Inc.

The management of pediatric liver trauma has evolved significantly over the last few decades. While surgical intervention was frequently and mostly unsuccessfully practiced during the first half of the last century, the 1960s were witness to the birth and gradual acceptance of non-operative management of these injuries. In 2000, the American Pediatric Surgical Association (APSA) Trauma Committee disseminated evidenced-based guidelines to help guide the non-operative management of pediatric blunt solid organ injury. The guidelines significantly contributed to conformity in the management of these patients. Since then, a number of well-designed studies have questioned the strict categorization of these injuries and have led to a renewed reliance on clinical signs of the patient's hemodynamic status. In 2019, APSA introduced an updated set of guidelines emphasizing the use of physiologic status rather than radiologic grade as a driver of clinical decision making for these injuries. This review will focus on liver injuries, in particular blunt injury, as this mechanism is by far the most commonly seen in children. Procedures required when non-operative management fails will be detailed, including surgery, angioembolization, and less commonly employed interventions. Finally, the updated inpatient and post-discharge aspects of care will be reviewed, including hemoglobin monitoring, bedrest, length of hospital stay, and activity restriction., (Copyright © 2020.

Background: Optimal timing for resection of asymptomatic congenital lung malformations (CLMs) remains controversial. The aim of this study is to define optimal timing for surgical intervention of patients with CLMs and define clinical variables that affect surgical outcomes. Methods: An IRB-approved retrospective analysis was conducted for patients undergoing surgery for CLMs between 2012 and 2017. Subjects were divided into cohorts based on timing of operative intervention. "Early intervention" was defined as surgery within 4 months of birth; "intermediate intervention"-between 4 and 6 months; and "late intervention"-6-12 months. Surgical outcomes including intraoperative estimated blood loss (EBL), surgical time, post-operative pneumothorax, length of time chest tube stayed in, and hospital length of stay were compared among the three groups using Fisher's exact test or Chi-squared test for categorical variables and one-way analysis of variance test for continuous variables. Results: We analyzed 63 patients who underwent surgery for CLM. There were no significant differences in baseline characteristics. Timing of surgery did not significantly correlate with post-operative outcomes. Specifically, there was no difference in operative time, EBL, post-operative pneumothorax, or length of hospital stay among the early, intermediate, and late intervention groups. Even after controlling for cyst-volume ratio (CVR), timing of surgery still did not affect post-operative outcomes. Conclusions: Surgical outcomes for resection of CLMs are not significantly affected by timing of surgery. We advocate for early intervention to decrease the incidence of associated complications that can occur with later intervention., (Copyright © 2020 Duron, Zenilman, Griggs, DeFazio, Price, Fan, Vivero, Castrillon, Schmaedick, Iqbal and Rothenberg.)

Background: Congenital diaphragmatic hernia (CDH) occurs in 1 out of 2500-3000 live births. Right-sided CDHs (R-CDHs) comprise 25% of all CDH cases, and data are conflicting on outcomes of these patients. The aim of our study was to compare outcomes in patients with right versus left CDH (L-CDH)., Methods: We analyzed a multicenter prospectively enrolled database to compare baseline characteristics and outcomes of neonates enrolled from January 2005 to January 2019 with R-CDH vs. L-CDH., Results: A total of 588, 495 L-CDH, and 93 R-CDH patients with CDH were analyzed. L-CDHs were more frequently diagnosed prenatally (p=0.011). Lung-to-head ratio was similar in both cohorts. R-CDHs had a lower frequency of primary repair (p=0.022) and a higher frequency of need for oxygen at discharge (p=0.013). However, in a multivariate analysis, need for oxygen at discharge was no longer significantly different. There were no differences in long-term neurodevelopmental outcomes assessed at two year follow up. There was no difference in mortality, need for ECMO, pulmonary hypertension, or hernia recurrence., Conclusion: In this large series comparing R to L-CDH patients, we found no significant difference in mortality, use of ECMO, or pulmonary complications. Our study supports prior studies that R-CDHs are relatively larger and more often require a patch or muscle flap for repair., Type of Study: Prognosis study LEVEL OF EVIDENCE: Level II., (Copyright © 2019 Elsevier Inc.

It has been shown that pressure ulcer formation in critically ill paediatric patients increases morbidity and mortality. We sought to identify factors associated with pressure ulcer formation in paediatric patients on extracorporeal membrane oxygenation (ECMO). From December 2014 to 2015, we identified patients at our institution who developed a pressure ulcer to create two cohorts: ulcer and no ulcer. Variables of interest included: type of ECMO, ECMO indication, hours on ECMO, location of cannulas, volume of crystalloid and blood products received during the first 7 days or during the length of the ECMO run, albumin and lactate levels on the day of cannulation, and presence of vasopressor support or steroid therapy. Of 43 patients studied, 11 (25.5%) developed a pressure ulcer. Patients that developed ulcers were older (P = 0.001) and weighed more (P = 0.006). Femoral cannulation was more frequent in the ulcer group (36.4% vs 6.3%, P = 0.029), and duration of ECMO was longer (P = 0.007). Age, weight, duration of ECMO, and femoral cannulation may contribute to the development of pressure ulcers in children who require ECMO support. Further analysis is imperative to identify specific techniques and protocols that will prevent pressure ulcers in this critically ill population., (© 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Background: Aggressive fluid resuscitative strategies have been the cornerstone of early trauma management for decades. However, recent prospective adult studies have challenged this practice, underlining the detrimental effect of positive fluid balance on cardiopulmonary function. Fluid overload has been associated with impaired oxygenation and morbidity in critically ill adults, but data is lacking in pediatric trauma patients., Methods: We completed a retrospective chart review of all pediatric trauma patients 0-18 years old admitted to a level 1 trauma center from January 2013 to December 2015. Four patient cohorts were established based on volume of fluid administered: <20 ml/kg/day, 20-40 ml/kg/day, 40-60 ml/kg/day, and > 60 ml/kg/day. The primary outcome was death. Secondary outcomes included the number of days on the ventilator, intensive care unit length of stay (ICU LOS), overall length of stay (LOS), number of days nil per os (NPO) as an indicator of ileus, and incidence of bloodstream infection and/or surgical site infection., Results: The mean volume of fluid administered over the first 24 h was 41 ml/kg/day, and 28 ml/kg/day over the first 48 h. ICU length of stay and overall length of stay were increased in patients who received more than 60 ml/kg/day in the first 24 h of their hospitalization. Furthermore, ventilator use, ICU length of stay, overall length of stay, and time to resumption of a regular diet were all increased in patients who received >60 ml/kg/day over 48 h., Conclusions: Early administration of high volumes of crystalloid fluid greater than 60 ml/kg/day significantly correlates with pulmonary complications, days NPO, and hospital length of stay. These results span the first 48 h of a patient's hospital stay and should encourage surgical care providers to exercise judicious use of crystalloid fluid administration in the trauma bay, ICU, and floor., Type of Study: Therapeutic., Level of Evidence: Level III., (Copyright © 2018 Elsevier Inc.

Background: In Peru, 11% of deaths are due to trauma. Iquitos is a large underserved Peruvian city isolated from central resources by its geography. Our objective was to implement a locally driven trauma registry to sustainably improve trauma healthcare in this region. Methods: All trauma patients presenting to the main regional referral hospital were included in the trauma registry. A pilot study retrospectively analyzed data from the first two months after implementation. Results: From March to April 2013, 572 trauma patients were entered into the database. Average age was 26.9 years. Ten percent of patients presented more than 24 hours after injury. Most common mechanisms of injury were falls (25.5%), motor vehicle collisions (23.3%), and blunt assault (10.5%). Interim analysis revealed that 99% of patients were entered into the database. However, documentation of vital signs was poor: 42% of patients had temperature, 26% had oxygen saturation documented. After reporting to registry staff, a significant increase in temperature (42 to 97%, P < 0.001) and oxygen saturation (26 to 92%, P < 0.001) documentation was observed. Conclusion: A trauma registry is possible to implement in a resource-poor setting. Future efforts will focus on analysis of data to enhance prevention and treatment of injuries in Iquitos.

Background: Prehospital traumatic cardiopulmonary arrest is associated with dismal prognosis, and patients rarely survive to hospital discharge. Recently established guidelines do not apply to the pediatric population because of paucity of data. The study objective was to determine the survival of pediatric patients presenting in the field with no signs of life after blunt trauma., Methods: We conducted a retrospective analysis of the National Trauma Data Bank research data set (2002-2010). All patients 18 years and younger with blunt traumatic injuries were identified (DRG International Classification of Diseases-9th Rev. codes 800-869). No signs of life (SOL) was defined on physical examination findings and included the following: pulse, 0; respiratory rate, 0; systolic blood pressure, 0; and no evidence of neurologic activity. These same criteria were reassessed on arrival at the emergency department (ED). Furthermore, we examined patients presenting to the ED who underwent resuscitative thoracotomy (Current Procedural Terminology code 34.02). Our primary outcome was survival to discharge from the hospital., Results: There were a total of 3,115,597 pediatric patients who were found in the field after experiencing blunt trauma. Of those, 7,766 (0.25%) had no SOL. Seventy percent of the patients with no SOL in the field were male. Survival to hospital discharge of all patients presenting with no SOL was 4.4% (n = 340). Twenty-five percent of the patients in the field with no SOL were successfully resuscitated in the field and regained SOL by the time they arrived to the ED (n = 1,913). Of those patients who regained SOL, 13.8% (n = 265) survived to hospital discharge. For patients in the field with no SOL, survival to discharge was significantly higher in patients who did not receive a resuscitative thoracotomy than in those who did., Conclusion: Survival of pediatric blunt trauma patients in the field without SOL is dismal. Resuscitative thoracotomy poses a heightened risk of blood-borne pathogen exposure to involved health care workers and is associated with a significantly lower survival rate., Level of Evidence: Prognostic study, level III; therapeutic study, level IV.

Objective: We aimed to improve the education of medical students involved in a longitudinal perinatal health improvement project in Gowa, Malawi., Design: We conducted qualitative interviews with students who participated in the project, reviewed their quantitative reports, and assessed the application of methodologies consonant with the learning objectives of a novel community health improvement course within their experience., Setting: The Gowa Health Promotions Project, designed to improve perinatal care for women and their families within the Gowa Health Clinic, used community participatory research strategies., Method: Medical students partnered with clinic workers and the local residents, evaluated, and revised an existing perinatal educational program. Qualitative and quantitative health and program data were collected, and program revisions were implemented. The value of the student experiences as a public health educational tool was evaluated by the authors., Results: Project sustainability was enhanced by a fellowship and planning for sequential students. The community health course structure and goals enhanced learning in the project. Engagement of investigators as early as possible in an international public health enhancement project improves student learning and ongoing commitment., Conclusion: Service learning objectives aimed at providing valuable medical learning to student learners immersed in other cultures are consistent with evidence-based learning objectives in the field of public health. Proactively structuring this experience to explicate these goals can enhance student learning. This dual strategy may improve the sustainability of international health programs by educating medical students while leading them into careers where these skills will be leveraged.

Background: Thyroidectomy is rarely complicated by a surgical site infection (SSI). Despite its low incidence, post-thyroidectomy SSI is especially concerning because of its proximity to vital head and neck structures and the very real potential for airway compromise and death. Severe SSIs frequently are caused by Group A Streptococcus (GAS) because of its potential for developing into necrotizing fascitis. No description of the surgical approach to a necrotizing soft-tissue infection after thyroid resection is available in the current literature., Methods: Case report and review of the pertinent English-language literature., Results: A 47-year-old male underwent a right thyroid lobectomy and isthmusectomy for a follicular neoplasm. On post-operative day 2, the patient presented to the emergency department with persistent pain, rapid onset of swelling, and airway compromise shown on computed tomography scan. Emergency incision and drainage revealed a severe soft tissue infection. Because of subsequent worsening erythema and soft-tissue swelling, the patient had to be re-explored. The infection, later identified as caused by GAS, might have been transmitted from the patient's daughter., Conclusion: To our knowledge, this is the first case reported of exposure to a family member with GAS pharyngitis. Successful treatment requires an appropriately high level of suspicion followed by emergent operative debridement and systemic antibiotics.

Robotic surgery has recently started to be used for minimally invasive colorectal surgery. Because of limited access and high cost, very few colorectal units are available in the US. We describe our experience with benign and malignant disease since September 2008 in a dedicated colorectal practice. A prospective collected robotic database was queried for colon and rectal procedures. Anonymized demographic, intraoperative, and postoperative data, and pathology information, were collected and analyzed. A total of 48 robotic procedures for colorectal maladies were performed in the study period. There were 35 females and 13 males. The average age was 57 years. Twenty-two cases were performed for diverticulitis, 13 for malignancy (10 distal rectum (<8 cm anal verge), two rectosigmoid, and one ascending colon cancer), 10 for rectal prolapse, two for rectovaginal fistula, and one for incidental appendiceal mucocele found during a gynecologic resection. The average operating room time (OR) was 162 min and there were no conversions to open procedures. Blood loss averaged 104 mL. Mean length of hospital stay (LOS) was 5.4 days. Patient readmission occurred in 27.3% of cases. The anastamotic leak rate was 2.1% (one patient). No mortalities were reported. When the analysis was performed for colorectal malignancies (13 procedures), there were nine females and four males. Average age was 59 years. The mean OR time was 191.1 min. Mean intraoperative blood loss was 123 mL and there were no conversions to open surgery. Average LOS was 7.0 days. There was one anastamotic leak (7.7%). The length of stay was increased for the patient with anastamotic leak (18 days) and for a patient with high stoma output and postoperative ileus (17 days). Readmission rate was 30.1%. The total number of lymph nodes retrieved averaged 19.5, with a mean distal margin of 3.0 cm and in all cases negative radial margins. Robotic colorectal surgery for benign and malignant disease is safe, and short-term outcomes are comparable with those of traditional and laparoscopic surgery. Oncologic resections were adequate with excellent lymph node sampling and radial and distal margins.

Pain must be managed during treatment of a patient with a chronic wound. Failure to do so will impair the patient's ability to heal significantly. Understanding the wound's etiology is essential for designing the wound-healing protocol and implementing its pain management regimen, of which a critical part is the chronic-wound patient's self-assessed scores of pain and functionality. In this report we present a paradigm for treating all chronic wounds, which was subsequently applied to 32 consecutive patients. Our integrated-team approach to managing the treatment of wounds includes accurate evaluation of the progression of patients' pain. Directors of the pain-management team and wound team have jointly managed hundreds of patients--either hospitalized or seen in both outpatient clinical practices. The three general categories for etiologies of the 10 most common types of chronic wounds are: ischemia, neuropathy, and direct tissue damage (e.g. pressure ulcers and venous stasis ulcers). Each of these are treated with unique analgesic regimens focused on surgical/medical management of the wound: oral and parenteral medications in combinations designed to facilitate specific additive analgesic effects and nerve blocks and implantable devices for correcting underlying wound pathophysiology. Successful treatment of pain generally results in increased functional independence and improvement of the patient's quality of life. We integrated wound-care pain-management team established guidelines that delineate the causes of chronic wounds and categorize treatment options for practical clinical use. The expectation is that all pain should be resolved in all patients if both the wound-healing and pain-healthcare providers use current technologies and drugs.
