- Abstract
Background: Multiple major health organisations recommend the use of extracorporeal membrane oxygenation (ECMO) support for COVID-19-related acute hypoxaemic respiratory failure. However, initial reports of ECMO use in patients with COVID-19 described very high mortality and there have been no large, international cohort studies of ECMO for COVID-19 reported to date. Methods: We used data from the Extracorporeal Life Support Organization (ELSO) Registry to characterise the epidemiology, hospital course, and outcomes of patients aged 16 years or older with confirmed COVID-19 who had ECMO support initiated between Jan 16 and May 1, 2020, at 213 hospitals in 36 countries. The primary outcome was in-hospital death in a time-to-event analysis assessed at 90 days after ECMO initiation. We applied a multivariable Cox model to examine whether patient and hospital factors were associated with in-hospital mortality. Findings: Data for 1035 patients with COVID-19 who received ECMO support were included in this study. Of these, 67 (6%) remained hospitalised, 311 (30%) were discharged home or to an acute rehabilitation centre, 101 (10%) were discharged to a long-term acute care centre or unspecified location, 176 (17%) were discharged to another hospital, and 380 (37%) died. The estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 37·4% (95% CI 34·4–40·4). Mortality was 39% (380 of 968) in patients with a final disposition of death or hospital discharge. The use of ECMO for circulatory support was independently associated with higher in-hospital mortality (hazard ratio 1·89, 95% CI 1·20–2·97). In the subset of patients with COVID-19 receiving respiratory (venovenous) ECMO and characterised as having acute respiratory distress syndrome, the estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 38·0% (95% CI 34·6–41·5). Interpretation: In patients with COVID-19 who received ECMO, both estimated

- Abstract
Use of extracorporeal membrane oxygenation (ECMO) in children receiving haematopoietic cell transplantation (HCT) and immune effector cell therapy is controversial and evidence-based guidelines have not been established. Remarkable advancements in HCT and immune effector cell therapies have changed expectations around reversibility of organ dysfunction and survival for affected patients. Herein, members of the Extracorporeal Life Support Organization (ELSO), Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network (HCT and cancer immunotherapy subgroup), the Pediatric Diseases Working Party of the European Society for Blood and Marrow Transplantation (EBMT), the supportive care committee of the Pediatric Transplantation and Cellular Therapy Consortium (PTCTC), and the Pediatric Intensive Care Oncology Kids in Europe Research (POKER) group of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC) provide consensus recommendations on the use of ECMO in children receiving HCT and immune effector cell therapy. These are the first international, multidisciplinary consensus-based recommendations on the use of ECMO in this patient population. This Review provides a clinical decision support tool for paediatric haematologists, oncologists, and critical care physicians during the difficult decision-making process of ECMO candidacy and management. These recommendations can represent a base for future research studies focused on ECMO selection criteria and bedside management.

- Abstract
Disclaimer: The Extracorporeal Life Support Organization (ELSO) Coronavirus Disease 2019 (COVID-19) Guidelines have been developed to assist existing extracorporeal membrane oxygenation (ECMO) centers to prepare and plan provision of ECMO during the ongoing pandemic. The recommendations have been put together by a team of interdisciplinary ECMO providers from around the world. Recommendations are based on available evidence, existing best practice guidelines, ethical principles, and expert opinion. This is a living document and will be regularly updated when new information becomes available. ELSO is not liable for the accuracy or completeness of the information in this document. These guidelines are not meant to replace sound clinical judgment or specialist consultation but rather to strengthen provision and clinical management of ECMO specifically, in the context of the COVID-19 pandemic.

- Abstract
WHO interim guidelines recommend offering extracorporeal membrane oxygenation (ECMO) to eligible patients with acute respiratory distress syndrome (ARDS) related to coronavirus disease 2019 (COVID-19). The number of patients with COVID-19 infection who might develop severe ARDS that is refractory to maximal medical management and require this level of support is currently unknown. Available evidence from similar patient populations suggests that carefully selected patients with severe ARDS who do not benefit from conventional treatment might be successfully supported with venovenous ECMO. The need for ECMO is relatively low and its use is mostly restricted to specialised centres globally. Providing complex therapies such as ECMO during outbreaks of emerging infectious diseases has unique challenges. Careful planning, judicious resource allocation, and training of personnel to provide complex therapeutic interventions while adhering to strict infection control measures are all crucial components of an ECMO action plan. ECMO can be initiated in specialist centres, or patients can receive ECMO during transportation from a centre that is not specialised for this procedure to an expert ECMO centre. Ensuring that systems enable safe and coordinated movement of critically ill patients, staff, and equipment is important to improve ECMO access. ECMO preparedness for the COVID-19 pandemic is important in view of the high transmission rate of the virus and respiratory-related mortality.

Multi-dentate ligands are instrumental to extraction and separations chemistry associated with nuclear fuel reprocessing. Specifically, the TALSPEAK (Trivalent Actinide Lanthanide Separation by Phosphorus reagent Extraction from Aqueous Komplexations) process utilises DTPA to facilitate the separation of minor actinides, MA3+ (Am3+ and Cm3+), from Ln3+ and Y3+, allowing the MA3+ to be reprocessed further by transmutation. The TALSPEAK process involves the preferential extraction of the major component (Ln3+) into the organic phase using HDEHP, while the DTPA-derived ligands remain in the aqueous phase coordinating MA3+ which favour soft donor interactions. The process requires the use of lactic acid as a buffer to maintain pH 3.6 in order to prevent the precipitation of DTPA complexes at low pH, commonly experienced during the processing cycle. Amino acid conjugates derived from EDTA and DTPA present ideal candidates as self-buffering DTPA/EDTA ligands, therefore removing the need for lactic acid in the TALSPEAK process. The ligands (right) produce an internal buffer pH 1.5-2.5 at μM to mM concentrations. The synthesis, coordination chemistry, photophysical properties and separation behaviour of these new ligands and stability towards ionising radiation is presented.

- Abstract
Extracorporeal membrane oxygenation (ECMO) provides temporary cardiorespiratory support for neonatal, pediatric, and adult patients when traditional management has failed. This lifesaving therapy has intrinsic risks, including the development of a robust inflammatory response, acute kidney injury (AKI), fluid overload (FO), and blood loss via consumption and coagulopathy. Continuous kidney replacement therapy (CKRT) has been proposed to reduce these side effects by mitigating the host inflammatory response and controlling FO, improving outcomes in patients requiring ECMO. The Pediatric Continuous Renal Replacement Therapy (PCRRT) Workgroup and the International Collaboration of Nephrologists and Intensivists for Critical Care Children (ICONIC) met to highlight current practice standards for ECMO use within the pediatric population. This review discusses ECMO modalities, the pathophysiology of inflammation during an ECMO run, its adverse effects, various anticoagulation strategies, and the technical aspects and outcomes of implementing CKRT during ECMO in neonatal and pediatric populations. Consensus practice points and guidelines are summarized. ECMO should be utilized in patients with severe acute respiratory failure despite the use of conventional treatment modalities. The Extracorporeal Life Support Organization (ELSO) offers guidelines for ECMO initiation and management while maintaining a clinical registry of over 195,000 patients to assess outcomes and complications. Monitoring and preventing fluid overload during ECMO and CKRT are imperative to reduce mortality risk.

- Abstract
Purpose: Preterm pediatric patients with bronchopulmonary dysplasia (BPD) represent a subgroup previously deemed high risk candidates for ECLS (extracorporeal life support) due to suspected high mortality or increased post ECLS morbidity. The aim of this study was to determine outcomes for patients with an established history of BPD who subsequently required ECLS., Methods: A single center retrospective review was performed between 01/2010-06/2022 for patients less than 2 years of age, born prematurely (<32 weeks) with a subsequent diagnosis of BPD, and who required ECLS for respiratory failure. Demographic and clinical data, including ECLS data, were collected. Speech, language, feeding/swallowing, cognitive, hearing, vision, or motor function deficits were obtained with a median follow up of 42 months following discharge., Results: Nineteen patients met criteria. The median birth weight and gestational age was 0.86 kg (IQR 0.73, 1.0) and 26 weeks (IQR 25, 27), respectively. The median chronological age at cannulation was 12.1 months. The most common etiologies for respiratory failure requiring ECLS were viral (68.4%) and bacterial (21.1%) pneumonia. Survival to decannulation was 78.9% (15/19) and survival to hospital discharge was 63.2% (12/19). Amongst survivors to discharge, 42% (5/12) required new or additional home oxygen and 50% (6/12) were noted to have neurodevelopmental/behavioral concerns on follow up at 1 year with 25% (3/12) with concerns beyond a year., Conclusion: Patients with underlying BPD who require ECLS have comparable mortality and long-term neurodevelopmental outcomes to non-BPD patients with respiratory failure. This information can be useful when considering ECLS candidacy and providing family counseling., 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.

- Abstract
To characterize kidney replacement therapy (KRT) and pediatric extracorporeal membrane oxygenation (ECMO) outcomes and to identify the optimal timing of KRT initiation during ECMO associated with increased survival. Observational retrospective cohort study using the Extracorporeal Life Support Organization Registry database in children (0-18 yo) on ECMO from January 1, 2016, to December 31, 2020. Of the 14,318 ECMO runs analyzed, 26% of patients received KRT during ECMO. Patients requiring KRT before ECMO had increased mortality to ECMO decannulation (29% vs. 17%, OR 1.97, P < 0.001) and to hospital discharge (58% vs. 39%, OR 2.16, P < 0.001). Patients requiring KRT during ECMO had an increased mortality to ECMO decannulation (25% vs. 15%, OR 1.85, P < 0.001) and to hospital discharge (56% vs. 34%, OR 2.47, P < 0.001). Multivariable logistic regression demonstrated that the need for KRT during ECMO was an independent predictor for mortality to ECMO decannulation (OR 1.49, P < 0.001) and to hospital discharge (OR 2.02, P < 0.001). Patients initiated on KRT between 24 and 72 hours after cannulation were more likely to survive to ECMO decannulation and showed a trend towards survival to hospital discharge as compared to those initiated before 24 hours and after 72 hours., Competing Interests: Disclosure: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article.

- Abstract
The Extracorporeal Life Support Organization (ELSO) maintains the world's largest extracorporeal membrane oxygenation (ECMO) registry by volume, center participation, and international scope. This 2022 ELSO Registry Report describes the program characteristics of ECMO centers, processes of ECMO care, and reported outcomes. Neonates (0-28 days), children (29 days-17 years), and adults (≥18 years) supported with ECMO from 2009 through 2022 and reported to the ELSO Registry were included. This report describes adjunctive therapies, support modes, treatments, complications, and survival outcomes. Data are presented descriptively as counts and percent or median and interquartile range (IQR) by year, group, or level. Missing values were excluded before calculating descriptive statistics. Complications are reported per 1,000 ECMO hours. From 2009 to 2022, 154,568 ECMO runs were entered into the ELSO Registry. Seven hundred and eighty centers submitted data during this time (557 in 2022). Since 2009, the median annual number of adult ECMO runs per center per year increased from 4 to 15, whereas for pediatric and neonatal runs, the rate decreased from 12 to 7. Over 50% of patients were transferred to the reporting ECMO center; 20% of these patients were transported with ECMO. The use of prone positioning before respiratory ECMO increased from 15% (2019) to 44% (2021) for adults during the coronavirus disease-2019 (COVID-19) pandemic. Survival to hospital discharge was greatest at 68.5% for neonatal respiratory support and lowest at 29.5% for ECPR delivered to adults. By 2022, the Registry had enrolled its 200,000th ECMO patient and 100,000th patient discharged alive. Since its inception, the ELSO Registry has helped centers measure and compare outcomes across its member centers and strategies of care. Continued growth and development of the Registry will aim to bolster its utility to patients and centers., Competing Interests: Disclosure: J.E.T. is the Chair of the Registry Committee of the Extracorporeal Life Support Organization (ELSO).

- Abstract
Background: The high-quality evidence on managing COVID-19 patients requiring extracorporeal membrane oxygenation (ECMO) support is insufficient. Furthermore, there is little consensus on allocating ECMO resources when scarce. The paucity of evidence and the need for guidance on controversial topics required an international expert consensus statement to understand the role of ECMO in COVID-19 better. Twenty-two international ECMO experts worldwide work together to interpret the most recent findings of the evolving published research, statement formulation, and voting to achieve consensus., Objectives: To guide the next generation of ECMO practitioners during future pandemics on tackling controversial topics pertaining to using ECMO for patients with COVID-19-related severe ARDS., Methods: The scientific committee was assembled of five chairpersons with more than 5 years of ECMO experience and a critical care background. Their roles were modifying and restructuring the panel's questions and, assisting with statement formulation in addition to expert composition and literature review. Experts are identified based on their clinical experience with ECMO (minimum of 5 years) and previous academic activity on a global scale, with a focus on diversity in gender, geography, area of expertise, and level of seniority. We used the modified Delphi technique rounds and the nominal group technique (NGT) through three face-to-face meetings and the voting on the statement was conducted anonymously. The entire process was planned to be carried out in five phases: identifying the gap of knowledge, validation, statement formulation, voting, and drafting, respectively., Results: In phase I, the scientific committee obtained 52 questions on controversial topics in ECMO for COVID-19, further reviewed for duplication and redundancy in phase II, resulting in nine domains with 32 questions with a validation rate exceeding 75% (Fig. 1). In phase III, 25 questions were used to formulate 14 statements, and six questions achieved no consensus on the statements. In phase IV, two voting rounds resulted in 14 statements that reached a consensus are included in four domains which are: patient selection, ECMO clinical management, operational and logistics management, and ethics., Conclusion: Three years after the onset of COVID-19, our understanding of the role of ECMO has evolved. However, it is incomplete. Tota14 statements achieved consensus; included in four domains discussing patient selection, clinical ECMO management, operational and logistic ECMO management and ethics to guide next-generation ECMO providers during future pandemic situations., (© 2023.

- Abstract
Introduction: The addition of cephalic drains (CDs) in extracorporeal membrane oxygenation (ECMO) to augment venous drainage may offer benefit, though their use is varied. Our objective was to describe our institution's experience with CDs including flow rates and patency. We also compared complication rates between patients with and without a CD., Methods: This retrospective cohort study included infants <12 months of age cannulated for ECMO between January 1, 2010 and September 30, 2019 at a single institution. Flow data were obtained for those with a CD. Demographic and complication rates were obtained for all., Results: Of 264 patients in the final cohort, 220 (83%) had a CD of which 93.2% remained patent to decannulation. CDs typically provided 30% or more of ECMO flow throughout the ECMO run. The median time to CD clot was 139 h (range 48-635 h). Patients with a clotted CD had longer ECMO runs than those whose CD remained patent (median 382 h [IQR 217-538] vs 139 h [IQR 91-246], p < 0.001). Survival to discharge was lower for those with clotted versus patent CD (14% vs 70%, p < 0.001). Mechanical complications were more common in patients with CD ( p = 0.005). Seizures were more common in those without a CD ( p = 0.021)., Conclusions: In this cohort, the majority of CDs placed remained patent at decannulation and provided substantial additional venous drainage. Mechanical problems were common in patients with CDs, but without clinical sequelae. Further study is warranted to elucidate CD impact on short- and long-term outcomes.

- Abstract
Combined advances in haematopoietic cell transplantation (HCT) and intensive care management have improved the survival of patients with haematological malignancies admitted to the intensive care unit. In cases of refractory respiratory failure or refractory cardiac failure, these advances have led to a renewed interest in advanced life support therapies, such as extracorporeal membrane oxygenation (ECMO), previously considered inappropriate for these patients due to their poor prognosis. Given the scarcity of evidence-based guidelines on the use of ECMO in patients receiving HCT and the need to provide equitable and sustainable access to ECMO, the European Society of Intensive Care Medicine, the Extracorporeal Life Support Organization, and the International ECMO Network aimed to develop an expert consensus statement on the use of ECMO in adult patients receiving HCT. A steering committee with expertise in ECMO and HCT searched the literature for relevant articles on ECMO, HCT, and immune effector cell therapy, and developed opinion statements through discussions following a Quaker-based consensus approach. An international panel of experts was convened to vote on these expert opinion statements following the Research and Development/University of California, Los Angeles Appropriateness Method. The Appraisal of Guidelines for Research and Evaluation statement was followed to prepare this Position Paper. 36 statements were drafted by the steering committee, 33 of which reached strong agreement after the first voting round. The remaining three statements were discussed by all members of the steering committee and expert panel, and rephrased before an additional round of voting. At the conclusion of the process, 33 statements received strong agreement and three weak agreement. This Position Paper could help to guide intensivists and haematologists during the difficult decision-making process regarding ECMO candidacy in adult patients receiving HCT. The statements could also serve as a basis for future research focused on ECMO selection criteria and bedside management., Competing Interests: Declaration of interests DB has received research support from and provided consultation to LivaNova; has been on the medical advisory boards for Abiomed, Xenios, Medtronic, Inspira, and Cellenkos; and is the president-elect of ELSO and the Chair of the Executive Committee of the International ECMO Network.

- Abstract
Use of extracorporeal membrane oxygenation (ECMO) in children receiving haematopoietic cell transplantation (HCT) and immune effector cell therapy is controversial and evidence-based guidelines have not been established. Remarkable advancements in HCT and immune effector cell therapies have changed expectations around reversibility of organ dysfunction and survival for affected patients. Herein, members of the Extracorporeal Life Support Organization (ELSO), Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network (HCT and cancer immunotherapy subgroup), the Pediatric Diseases Working Party of the European Society for Blood and Marrow Transplantation (EBMT), the supportive care committee of the Pediatric Transplantation and Cellular Therapy Consortium (PTCTC), and the Pediatric Intensive Care Oncology Kids in Europe Research (POKER) group of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC) provide consensus recommendations on the use of ECMO in children receiving HCT and immune effector cell therapy. These are the first international, multidisciplinary consensus-based recommendations on the use of ECMO in this patient population. This Review provides a clinical decision support tool for paediatric haematologists, oncologists, and critical care physicians during the difficult decision-making process of ECMO candidacy and management. These recommendations can represent a base for future research studies focused on ECMO selection criteria and bedside management., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2022 Elsevier Ltd.

- Abstract
WHO interim guidelines recommend offering extracorporeal membrane oxygenation (ECMO) to eligible patients with acute respiratory distress syndrome (ARDS) related to coronavirus disease 2019 (COVID-19). The number of patients with COVID-19 infection who might develop severe ARDS that is refractory to maximal medical management and require this level of support is currently unknown. Available evidence from similar patient populations suggests that carefully selected patients with severe ARDS who do not benefit from conventional treatment might be successfully supported with venovenous ECMO. The need for ECMO is relatively low and its use is mostly restricted to specialised centres globally. Providing complex therapies such as ECMO during outbreaks of emerging infectious diseases has unique challenges. Careful planning, judicious resource allocation, and training of personnel to provide complex therapeutic interventions while adhering to strict infection control measures are all crucial components of an ECMO action plan. ECMO can be initiated in specialist centres, or patients can receive ECMO during transportation from a centre that is not specialised for this procedure to an expert ECMO centre. Ensuring that systems enable safe and coordinated movement of critically ill patients, staff, and equipment is important to improve ECMO access. ECMO preparedness for the COVID-19 pandemic is important in view of the high transmission rate of the virus and respiratory-related mortality., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

- Abstract
Objective: Pediatric traumatic brain injury is a major public health problem in the United States. Hypertonic saline therapy is a well-established treatment in patients with severe traumatic brain injury (Glasgow Coma Scale ≤ 8) who have intracranial hypertension. In children, fluid overload is associated with increased mortality, ventilator duration, and length of PICU stay, even when controlling for severity of illness. This study reports prevalence of fluid overload in pediatric patients with severe traumatic brain injury treated with 3% hypertonic saline and effect on clinical outcomes., Design: Single-center retrospective chart review., Setting: PICUs at two tertiary children's hospitals., Patients: One hundred thirty-eight patients with traumatic brain injury with postresuscitation Glasgow Coma Scale less than or equal to 8 who received hypertonic saline from September 1, 2010, to February 28, 2016, and intracranial pressure monitoring and survived at least 24 hours from admission., Interventions: None., Measurements and Main Results: We used fluid balance percentage greater than or equal to 10% as our definition of fluid overload. Ninety-one percent of patients less than 1 year old had fluid overload on day 10 of admission compared with 47% of patients greater than 1 year. Fluid overloaded patients did not have increased mortality, acute kidney injury, PICU length of stay, or ventilator days. Hypertonic saline was not the cause of fluid overload in these patients., Conclusions: Patients with severe traumatic brain injury do have high rates of fluid overload. However, fluid overload did not contribute to mortality, longer days on the ventilator, increased risk of acute kidney injury, or increased PICU length of stay.

- Abstract
Objective: The objective was to compare the resolution of organ dysfunction, 28-day mortality, and biochemical markers in children with thrombocytopenia-associated multiple organ failure who received therapeutic plasma exchange versus no therapeutic plasma exchange., Design: Observational longitudinal cohort study., Setting: Nine U.S. PICUs., Patients: Eighty-one children with sepsis-induced thrombocytopenia-associated multiple organ failure., Interventions: Therapeutic plasma exchange., Measurements and Main Results: Adjusted relative risk for 28-day mortality was modeled using standard multivariate regression with propensity score weighting to reduce covariate confounding. Change from baseline Pediatric Logistic Organ Dysfunction scores between therapeutic plasma exchange and no therapeutic plasma exchange differed in temporal pattern during the first week (p = 0.009). By day 4, mean Pediatric Logistic Organ Dysfunction score declined by 7.9 points (95% CI, -10.8 to -5.1) in the therapeutic plasma exchange-treated group compared with no change with no therapeutic plasma exchange. Use of therapeutic plasma exchange was associated with reduced 28-day mortality by multivariate analysis (adjusted relative risk, 0.45; 95% CI, 0.23-0.90; p = 0.02) and by propensity score weighting (adjusted relative risk, 0.46; 95% CI, 0.22-0.97; p = 0.04)., Conclusions: Therapeutic plasma exchange use in thrombocytopenia-associated multiple organ failure was associated with a decrease in organ dysfunction. After accounting for several risk factors, 28-day all-cause mortality was lower in children treated with therapeutic plasma exchange compared with those receiving no therapeutic plasma exchange. A multicenter randomized clinical trial is necessary to determine a causal relationship.

- Abstract
Osteochondral defects of the talus are a challenging subject facing foot and ankle surgeons. The available treatment options have relatively good subjective outcomes; however, they are limited by the ability to reproduce hyaline cartilage, the need for multiple surgeries, and high morbidity. We present a new technique using DeNovo NT(®) juvenile allograft cartilage implantation introduced into a talar lesion arthroscopically in a single procedure to repair a posteriomedial talar osteochondral defects in a healthy, active 30-year-old female. The patient tolerated the procedure well. At the 6-month follow-up visit, the patient had returned to full activity, and at 24 months, she remained completely pain free., (Copyright © 2012 American College of Foot and Ankle Surgeons.

Osteomyelitis can be a challenging entity to treat. Because of the emergence of risk factors, including broad-spectrum antibiotics, intravenous drug abuse, immunocompromised hosts, and other factors, opportunistic pathogens have increased in prevalence in bone infections. A review of the published data revealed few reported cases of fungal osteomyelitis localized to the foot. In the present report, we describe a rare case of fungal osteomyelitis localized to the calcaneus in an elderly female patient who was successfully treated with surgical debridement and a 6-week course of oral fluconazole., (Copyright © 2012 American College of Foot and Ankle Surgeons.

- Abstract
Background: The 2009 pandemic influenza A (H1N1) (pH1N1) virus continues to circulate worldwide. Determining the roles of chronic conditions and bacterial coinfection in mortality is difficult because of the limited data for children with pH1N1-related critical illness., Methods: We identified children (<21 years old) with confirmed or probable pH1N1 admitted to 35 US PICUs from April 15, 2009, through April 15, 2010. We collected data on demographics, baseline health, laboratory results, treatments, and outcomes., Results: Of 838 children with pH1N1 admitted to a PICU, the median age was 6 years, 58% were male, 70% had ≥1 chronic health condition, and 88.2% received oseltamivir (5.8% started before PICU admission). Most patients had respiratory failure with 564 (67.3%) receiving mechanical ventilation; 162 (19.3%) received vasopressors, and 75 (8.9%) died. Overall, 71 (8.5%) of the patients had a presumed diagnosis of early (within 72 hours after PICU admission) Staphylococcus aureus coinfection of the lung with 48% methicillin-resistant S aureus (MRSA). In multivariable analyses, preexisting neurologic conditions or immunosuppression, encephalitis (1.7% of cases), myocarditis (1.4% of cases), early presumed MRSA lung coinfection, and female gender were mortality risk factors. Among 251 previously healthy children, only early presumed MRSA coinfection of the lung (relative risk: 8 [95% confidence interval: 3.1-20.6]; P < .0001) remained a mortality risk factor., Conclusions: Children with preexisting neurologic conditions and immune compromise were at increased risk of pH1N1-associated death after PICU admission. Secondary complications of pH1N1, including myocarditis, encephalitis, and clinical diagnosis of early presumed MRSA coinfection of the lung, were mortality risk factors.

- Abstract
Late hematogenous infection of previously asymptomatic orthopedic implants is extremely rare and usually associated with total joint replacements, such as those of the hip or knee. We present the case of an otherwise healthy female who developed a deep space infection 18 months after a first metatarsophalangeal joint implant arthroplasty. The patient presented with pain and swelling at the site, and over the course of several days developed fever and tachycardia and leukocytosis. Cultures of the surrounding soft tissues and the implant grew Streptococcus pneumoniae. The patient reported a 1- to 2-week history of symptoms consistent with an upper respiratory tract infection and it is believed that this distant focus of infection was the probable source of late hematogenous seeding of the first metatarsophalangeal joint implant., (Copyright 2010 American College of Foot and Ankle Surgeons.

- Abstract
Unlabelled: Osteochondral defects are frequently seen in patients with hallux limitus. Historically, such patients have been treated with cheilectomy, arthroplasty, osteotomy, fusion, and other joint destructive procedures. We present a case of a 54-year-old man who presented with a failed hemicap implant of the first metatarsal head. Seven months after his initial implant surgery, the patient was still experiencing pain and limited function despite conservative treatment efforts. In an effort to salvage the joint, an osteoarticular transfer system procedure was undertaken. After removal of the 12-mm hemicap implant, a 15 x 12 mm osteochondral plug was taken from the ipsilateral femoral condyle and press fit into the defect in the first metatarsal head. At 6 weeks postoperatively, complete consolidation of the graft was observed radiographically. By 6 months postoperatively, the patient was able to walk more than 15 miles per week without pain while wearing regular shoes. He was subsequently discharged at 1-year postoperatively, at which time he neither described nor demonstrated any signs or symptoms related to hallux limitus/rigidus. To our knowledge, this particular technique has not been previously reported for lesions of this size in the first metatarsal head., Level of Clinical Evidence: 4.

- Abstract
Soft tissue defects in patients with chronic comorbidities place these patients at high risk for amputation, even when their underlying problems are controlled. The reverse sural artery flap is an effective technique for closing these defects and saving the limb. We retrospectively reviewed 15 consecutive high-risk patients who underwent a sural artery flap procedure between 2003 and 2005 as a final attempt to prevent having a below-the-knee amputation. All of our patients presented with at least 1 comorbidity, with a majority having multiple. Comorbidities in our patient population consisted primarily of diabetes mellitus with neuropathy, critical limb ischemia, end-stage renal disease, and various cardiomyopathies. All patients presented before surgical intervention with a longstanding history of chronic ulcerations that had failed multiple healing strategies. Ulcerations were located at various regions of the foot and ankle such as the heel, lateral malleolus, medial malleolus, and the lateral midfoot. Of those 15 procedures, three failed completely and two had complete dermal necrosis with viable adipose tissue that healed secondarily. The remaining ten flaps healed primarily. We used negative pressure therapy preoperatively in seven patients and postoperatively in five patients. We obtained a success rate of 80%. The reverse sural artery flap has many advantages over free flaps, which has made it a viable treatment option in chronic ulcerations that have failed conservative attempts.

- Abstract
A case involving a benign osteochondral tumor of the talar dome is presented. Graft considerations are reviewed and some of their specific characteristics are highlighted. Selection of a fresh-frozen cadaveric graft in this case was based on the goal of maintaining articular congruity in the ankle joint. The authors' experience demonstrated that normal joint function can be preserved with this type of graft.

- Abstract
The purpose of this article is to introduce a modification of the Brostrom procedure to repair chronic lateral ankle instability. This technique involves utilizing an implantable anchoring system to simplify the plication of the injured capsular and ligamentous structures of the ankle. The advantage of this surgical technique is that it provides the surgeon with a relatively rapid, simple procedure that utilizes the proven technique first described by Brostrom in 1966.
