OBJECTIVES: To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction. DESIGN: A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process. METHODS: The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, "in our practice" statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate. RESULTS: The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 52 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, "in our practice" statements were provided. In addition, 49 research priorities were identified. CONCLUSIONS: A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

IMPORTANCE: The recent and ongoing coronavirus disease 2019 (COVID-19) pandemic has taken an unprecedented toll on adults critically ill with COVID-19 infection. While there is evidence that the burden of COVID-19 infection in hospitalized children is lesser than in their adult counterparts, to date, there are only limited reports describing COVID-19 in pediatric intensive care units (PICUs). OBJECTIVE: To provide an early description and characterization of COVID-19 infection in North American PICUs, focusing on mode of presentation, presence of comorbidities, severity of disease, therapeutic interventions, clinical trajectory, and early outcomes. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included children positive for COVID-19 admitted to 46 North American PICUs between March 14 and April 3, 2020. with follow-up to April 10, 2020. MAIN OUTCOMES AND MEASURES: Prehospital characteristics, clinical trajectory, and hospital outcomes of children admitted to PICUs with confirmed COVID-19 infection. RESULTS: Of the 48 children with COVID-19 admitted to participating PICUs, 25 (52%) were male, and the median (range) age was 13 (4.2-16.6) years. Forty patients (83%) had significant preexisting comorbidities; 35 (73%) presented with respiratory symptoms and 18 (38%) required invasive ventilation. Eleven patients (23%) had failure of 2 or more organ systems. Extracorporeal membrane oxygenation was required for 1 patient (2%). Targeted therapies were used in 28 patients (61%), with hydroxychloroquine being the most commonly used agent either alone (11 patients) or in combination (10 patients). At the completion of the follow-up period, 2 patients (4%) had died and 15 (31%) were still hospitalized, with 3 still requiring ventilatory support and 1 receiving extracorporeal membrane oxygenation. The median (range) PICU and hospital lengths of stay for those who had been discharged were 5 (3-9) days and 7 (4-13) days, respectively. CONCLUSIONS AND RELEVANCE: This early report describes the burden of COVID-19 infection in North American PICUs and confirms that severe illness in children is significant but far less frequent than in adults. Prehospital comorbidities appear to be an important factor in children. These preliminary observations provide an important platform for larger and more extensive studies of children with COVID-19 infection.

The prevalence of iron-deficiency anemia among infants and children in the United States is now relatively low, but iron deficiency remains the leading cause of anemia. Iron deficiency persists despite increased understanding of methods for its prevention, improvements in the means for its detection, and a greater recognition of the fact that anemia is only one manifestation of this systemic disease.The Prevalence of Iron Deficiency in InfancyThe prevalence of iron deficiency varies widely depending on the criteria used to establish the diagnosis. Variables include the age and socioeconomic status of the patients surveyed, the extent of the population's . . .

Increased availability of research-supported, school-based prevention programs, coupled with the growing national policy emphasis on use of evidence-based practices, has contributed to a shift in research priorities from efficacy to implementation and dissemination. A critical issue in moving research to practice is ensuring high-quality implementation of both the intervention model and the support system for sustaining it. The paper describes a three-level framework for considering the implementation quality of school-based interventions. Future directions for research on implementation are discussed.

Study objectiveTo determine whether primary snoring (PS) could be distinguished from childhood obstructive sleep apnea syndrome (OSAS) by clinical history.DesignRetrospective study of clinical history of 83 children with snoring and/or sleep disordered breathing who were referred for polysomnography.SettingTertiary referral center; pediatric pulmonary sleep apnea clinic.MeasurementsWe evaluated the ability of a clinical obstructive sleep apnea (OSA) score and other questions about sleep, breathing, and daytime symptoms to distinguish PS from OSAS in children. Parents were asked about the child's snoring, difficulty breathing, observed apnea, cyanosis, struggling to breathe, shaking the child to “make him or her breathe,” watching the child sleep, afraid of apnea, the frequency and loudness of snoring, and daytime symptoms such as excessive daytime sleepiness (EDS).ResultsBased on polysomnography results, 48 patients were classified as PS and 35 as OSAS. Peak end-tidal CO2 (49 ± 3.2 vs 55 ± 8.2 [SD] mm Hg); lowest arterial oxygen saturation measured by pulse oximetry (95 ± 1.9 vs 82 ± 14%); and apnea/hypopnea index (0.27 ± .3 vs 8.4 ± 6 events/h) indicated that the diagnostic criteria for PS versus OSA were reasonable. There were no differences between PS and OSA patients with respect to age, sex, race, failure to thrive, obesity, history of EDS, snoring history, history of cyanosis during sleep, or daytime symptoms except for mouth breathing. There were no significant differences in sleep variables between PS patients and those with any severity of OSAS. The OSA score misclassified about one of four patients. Comparing PS and OSA patients, significant findings were daytime mouth breathing (61 vs 85%; p=0.024); observed apnea (46 vs 74%; p=0.013); shaking the child (31 vs. 60%; p=0.01); struggling to breathe (58 vs 89%; p=0.003); and afraid of apnea (71 vs 91%; p=0.028). However, none of these were sufficiently discriminatory to predict OSAS.ConclusionWe conclude that PS in children cannot be reliably distinguished from OSAS by clinical history alone.

OBJECTIVES: Fever is one of the most common reasons that parents seek medical attention for their children. Parental concerns arise in part because of the belief that fever is a disease rather than a symptom or sign of illness. Twenty years ago, Barton Schmitt, MD, found that parents had numerous misconceptions about fever. These unrealistic concerns were termed "fever phobia." More recent concerns for occult bacteremia in febrile children have led to more aggressive laboratory testing and treatment. Our objectives for this study were to explore current parental attitudes toward fever, to compare these attitudes with those described by Schmitt in 1980, and to determine whether recent, more aggressive laboratory testing and presumptive treatment for occult bacteremia is associated with increased parental concern regarding fever. METHODS: Between June and September 1999, a single research assistant administered a cross-sectional 29-item questionnaire to caregivers whose children were enrolled in 2 urban hospital-based pediatric clinics in Baltimore, Maryland. The questionnaire was administered before either health maintenance or acute care visits at both sites. Portions of the questionnaire were modeled after Schmitt's and elicited information about definition of fever, concerns about fever, and fever management. Additional information included home fever reduction techniques, frequency of temperature monitoring, and parental recall of past laboratory workup and treatment that these children had received during health care visits for fever. RESULTS: A total of 340 caregivers were interviewed. Fifty-six percent of caregivers were very worried about the potential harm of fever in their children, 44% considered a temperature of 38.9 degrees C (102 degrees F) to be a "high" fever, and 7% thought that a temperature could rise to >/=43.4 degrees C (>/=110 degrees F) if left untreated. Ninety-one percent of caregivers believed that a fever could cause harmful effects; 21% listed brain damage, and 14% listed death. Strikingly, 52% of caregivers said that they would check their child's temperature </=1 hour when their child had a fever, 25% gave antipyretics for temperatures <37.8 degrees C (<100 degrees F), and 85% would awaken their child to give antipyretics. Fourteen percent of caregivers gave acetaminophen, and 44% gave ibuprofen at too frequent dosing intervals. Of the 73% of caregivers who said that they sponged their child to treat a fever, 24% sponged at temperatures </=37.8 degrees C (</=100 degrees F); 18% used alcohol. Forty-six percent of caregivers listed doctors as their primary resource for information about fever. Caregivers who stated that they were very worried about fever were more likely in the past to have had a child who was evaluated for a fever, to have had blood work performed on their child during a febrile illness, and to have perceived their doctors to be very worried about fever. Compared with 20 years ago, more caregivers listed seizure as a potential harm of fever, woke their children and checked temperatures more often during febrile illnesses, and gave antipyretics or initiated sponging more frequently for possible normal temperatures. CONCLUSIONS: Fever phobia persists. Pediatric health care providers have a unique opportunity to make an impact on parental understanding of fever and its role in illness. Future studies are needed to evaluate educational interventions and to identify the types of medical care practices that foster fever phobia.fever, fever phobia, child, children, antipyretics, sponging, health care practices.

The protein encoded by the human testis determining gene, SRY, contains a high mobility group (HMG) box related to that present in the T cell-specific, DNA-binding protein TCF-1. Recombinant SRY protein was able to bind to the same core sequence AACAAAG recognized by TCF-1 in a sequence dependent manner. In five XY females point mutations were found in the region encoding the HMG box. In four cases DNA binding activity of mutant SRY protein was negligible; in the fifth case DNA binding was reduced. These results imply that the DNA binding activity of SRY is required for sex determination.

BACKGROUND: Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. METHODS: We conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest. RESULTS: A total of 295 patients underwent randomization. Among the 260 patients with data that could be evaluated and who had a VABS-II score of at least 70 before cardiac arrest, there was no significant difference in the primary outcome between the hypothermia group and the normothermia group (20% vs. 12%; relative likelihood, 1.54; 95% confidence interval [CI], 0.86 to 2.76; P=0.14). Among all the patients with data that could be evaluated, the change in the VABS-II score from baseline to 12 months was not significantly different (P=0.13) and 1-year survival was similar (38% in the hypothermia group vs. 29% in the normothermia group; relative likelihood, 1.29; 95% CI, 0.93 to 1.79; P=0.13). The groups had similar incidences of infection and serious arrhythmias, as well as similar use of blood products and 28-day mortality. CONCLUSIONS: In comatose children who survived out-of-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a good functional outcome at 1 year.

An estimated 650,000 Americans will have ESRD by 2010. Young adults with kidney failure often develop progressive chronic kidney disease (CKD) in childhood and adolescence. The Chronic Kidney Disease in Children (CKiD) prospective cohort study of 540 children aged 1 to 16 yr and have estimated GFR between 30 and 75 ml/min per 1.73 m2 was established to identify novel risk factors for CKD progression; the impact of kidney function decline on growth, cognition, and behavior; and the evolution of cardiovascular disease risk factors. Annually, a physical examination documenting height, weight, Tanner stage, and standardized BP is conducted, and cognitive function, quality of life, nutritional, and behavioral questionnaires are completed by the parent or the child. Samples of serum, plasma, urine, hair, and fingernail clippings are stored in biosamples and genetics repositories. GFR is measured annually for 2 yr, then every other year using iohexol, HPLC creatinine, and cystatin C. Using age, gender, and serial measurements of Tanner stage, height, and creatinine, compared with iohexol GFR, a formula to estimate GFR that will improve on traditional pediatric GFR estimating equations when applied longitudinally is expected to be developed. Every other year, echocardiography and ambulatory BP monitoring will assess risk for cardiovascular disease. The primary outcome is the rate of decline of GFR. The CKiD study will be the largest North American multicenter study of pediatric CKD.

There are several diagnostic pitfalls in the interpretation of roentgenograms of the cervical spine in children with suspected neck injuries. Incomplete ossification, epiphyscal variations, unique bone architecture, and relative hypermobility may all contribute to possible diagnostic errors. In this study of 160 normal children's cervical spines, the following suspect normal variations were observed: 1. Variations due to displacement of vertebrae that may resemble subluxation: Marked anterior displacement of the second on the third cervical vertebra, resembling a true subluxation, was observed in 19 per cent of the children studied who were one to seven year old. A similar finding was present less frequently between the third and fourth cervical vertebrae. Overriding of the atlas on the odontoid process, seen on lateral roentgenograms made with the neck in extension, and apparrent wedening of the space between these two structures, visible on flexion views, occurred in 20 per cent of the normal children between one and seven years of age. Both were suggestive of ligamentous injury. 2. Variations of curvature of cervical spine that may resemble spasm and ligamentous injury: Absence of uniform angulation between adjacent vertebrae, absence of the normal lordotic curve in neutral position, and absence of a flexion curvature of the spine between the second and the seventh cervical vertebrae, seen on lateral roentgenograms made with the cervical spine in flexion, were seen at all ages between one and sixteen years, the incidence of each variation ranging between 14 and 16 per cent. 3. Variations related to skeletal growth centers resembling fractures: The presence of the basilar odontoid cartilaginous plate frequently persists in vestigial form until the age of five years or longer and may resemble an undisplaced fracture. The apical odontoid epiphysis is rarely seen on lateral roentgenograms, but should not be mistaken for a fracture. A secondary ossification center of a cervical spinous process was seen only once in this study; there was no resemblance to an avulsion fracture. A center of ossification in the first thoracic spinous process, however, did have some resemblance to a fracture. This variation would not appear to be a pitfall in the diagnosis of neck injury in children and adolescents. Physicians responsible for the care of children with neck injuries should be conversant with the normal roentgenographic variations.

Over the past 12 years, since the publication of the Institute of Medicine's report, “To Err is Human: Building a Safer Health System,” improving patient safety has been the focus of considerable public and professional interest. Although such efforts required changes in policies; education; workforce; and health care financing, organization, and delivery, the most important gap has arguably been in research. Specifically, to improve patient safety we needed to identify hazards, determine how to measure them accurately, and identify solutions that work to reduce patient harm. A 2001 report commissioned by the Agency for Healthcare Research and Quality, “Making Health Care Safer: A Critical Analysis of Patient Safety Practices” (1), helped identify some early evidence-based safety practices, but it also highlighted an enormous gap between what was known and what needed to be known.

BACKGROUND: Bronchiolitis, the most common infection of the lower respiratory tract in infants, is a leading cause of hospitalization in childhood. Corticosteroids are commonly used to treat bronchiolitis, but evidence of their effectiveness is limited. METHODS: We conducted a double-blind, randomized trial comparing a single dose of oral dexamethasone (1 mg per kilogram of body weight) with placebo in 600 children (age range, 2 to 12 months) with a first episode of wheezing diagnosed in the emergency department as moderate-to-severe bronchiolitis (defined by a Respiratory Distress Assessment Instrument score > or =6). We enrolled patients at 20 emergency departments during the months of November through April over a 3-year period. The primary outcome was hospital admission after 4 hours of emergency department observation. The secondary outcome was the Respiratory Assessment Change Score (RACS). We also evaluated later outcomes: length of hospital stay, later medical visits or admissions, and adverse events. RESULTS: Baseline characteristics were similar in the two groups. The admission rate was 39.7% for children assigned to dexamethasone, as compared with 41.0% for those assigned to placebo (absolute difference, -1.3%; 95% confidence interval [CI], -9.2 to 6.5). Both groups had respiratory improvement during observation; the mean 4-hour RACS was -5.3 for dexamethasone, as compared with -4.8 for placebo (absolute difference, -0.5; 95% CI, -1.3 to 0.3). Multivariate adjustment did not significantly alter the results, nor were differences detected in later outcomes. CONCLUSIONS: In infants with acute moderate-to-severe bronchiolitis who were treated in the emergency department, a single dose of 1 mg of oral dexamethasone per kilogram did not significantly alter the rate of hospital admission, the respiratory status after 4 hours of observation, or later outcomes. (ClinicalTrials.gov number, NCT00119002 [ClinicalTrials.gov].).

BACKGROUND: Targeted temperature management is recommended for comatose adults and children after out-of-hospital cardiac arrest; however, data on temperature management after in-hospital cardiac arrest are limited. METHODS: In a trial conducted at 37 children's hospitals, we compared two temperature interventions in children who had had in-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose children older than 48 hours and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a score of 70 or higher on the Vineland Adaptive Behavior Scales, second edition (VABS-II, on which scores range from 20 to 160, with higher scores indicating better function), was evaluated among patients who had had a VABS-II score of at least 70 before the cardiac arrest. RESULTS: The trial was terminated because of futility after 329 patients had undergone randomization. Among the 257 patients who had a VABS-II score of at least 70 before cardiac arrest and who could be evaluated, the rate of the primary efficacy outcome did not differ significantly between the hypothermia group and the normothermia group (36% [48 of 133 patients] and 39% [48 of 124 patients], respectively; relative risk, 0.92; 95% confidence interval [CI], 0.67 to 1.27; P=0.63). Among 317 patients who could be evaluated for change in neurobehavioral function, the change in VABS-II score from baseline to 12 months did not differ significantly between the groups (P=0.70). Among 327 patients who could be evaluated for 1-year survival, the rate of 1-year survival did not differ significantly between the hypothermia group and the normothermia group (49% [81 of 166 patients] and 46% [74 of 161 patients], respectively; relative risk, 1.07; 95% CI, 0.85 to 1.34; P=0.56). The incidences of blood-product use, infection, and serious adverse events, as well as 28-day mortality, did not differ significantly between groups. CONCLUSIONS: Among comatose children who survived in-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a favorable functional outcome at 1 year.

A long-term retrospective analysis of 248 patients, 11-25 years after surgical correction of coarctation of the aorta, revealed a high incidence of premature cardiovascular disease. Twelve percent of patients with follow-up have died. It is suggested that premature death in patients with adequate surgical repair may be related to the duration of preoperative hypertension. Fifty-nine patients were evaluated on a standard hospital protocol. Seventy-eight percent had evidence of cardiovascular disease and over 40% had no change or had increased blood pressure over the preoperative value. These data emphasize the importance of early diagnosis and treatment for patients with coarctation of the aorta as well as the need for close postoperative follow-up.

Sixty-three autistic children have been reevaluated at a mean age of 15 years after a mean follow-up period of 9 years. Almost one third have achieved at least a moderate social adjustment. The prognosis has been shown to vary significantly with the presence of useful speech at the age of 5, taken as an index of the severity of autistic isolation. Half of those who possessed meaningful language by the age of 5 improved, whereas only 1 of 31 without the ability to communicate verbally by that age has shown significant improvement. The clinical course of these children justifies the segregation of early infantile autism as a clinical entity, probably to be included within the group of schizophrenias. The psychopathology of autism has been reviewed and the suggestion offered that the fundamental feature is a disturbance in social perception.

OBJECTIVE: To determine the safety and feasibility of an early mobilization program in a PICU. DESIGN: Observational, pre-post design. SETTING: PICU in a tertiary academic hospital in the United States. PATIENTS: Critically ill pediatric patients admitted to the PICU. INTERVENTION: This quality improvement project involved a usual-care baseline phase, followed by a quality improvement phase that implemented a multicomponent, interdisciplinary, and tiered activity plan to promote early mobilization of critically ill children. MEASUREMENTS AND MAIN RESULTS: Data were collected and analyzed from July to August 2014 (preimplementation phase) and July to August 2015 (postimplementation). The study sample included 200 children 1 day through 17 years old who were admitted to the PICU and had a length of stay of at least 3 days. PICU Up! implementation led to an increase in occupational therapy consultations (44% vs 59%; p = 0.034) and physical therapy consultations (54% vs 66%; p = 0.08) by PICU day 3. The median number of mobilizations per patient by PICU day 3 increased from 3 to 6 (p < 0.001). More children engaged in mobilization activities after the PICU Up! intervention by PICU day 3, including active bed positioning (p < 0.001), and ambulation (p = 0.04). No adverse events occurred as a result of early mobilization activities. The most commonly reported barriers to early mobilization after PICU Up! implementation was availability of appropriate equipment. The program was positively received by PICU staff. CONCLUSIONS: Implementation of a structured and stratified early mobilization program in the PICU was feasible and resulted in no adverse events. PICU Up! increased physical therapy and occupational therapy involvement in the children's care and increased early mobilization activities, including ambulation. A bundled intervention to create a healing environment in the PICU with structured activity may have benefits for short- and long-term outcomes of critically ill children.

Given growing concerns regarding the prevalence and seriousness of bullying, the National Education Association recently drew upon its membership to launch a national study of teachers' and education support professionals' perceptions of bullying, and need for additional training on bullying prevention efforts and school-wide policies. The data were collected from a representative sample of 5,064 National Education Association members (2,163 teachers and 2,901 education support professionals). Analyses indicated that compared to education support professionals, teachers were more likely to witness students being bullied, more likely to view bullying as a significant problem at their school, and were more likely to have students report bullying to them. Teachers were more likely to be involved in bullying policies at their school, yet both groups reported wanting more training related to cyberbullying and bullying related to students' sexual orientation, gender issues, and racial issues. Implications for school psychologists and the development of school-wide bullying prevention efforts are discussed.

BACKGROUND: Various types of spinal implants have been used with the objective of minimizing spinal deformities while maximizing the spine and thoracic growth in a growing child with a spinal deformity. PURPOSE: The aim of this study was to describe a classification system of growth friendly spinal implants to allow researchers and clinicians to have a common language and facilitate comparative studies. Growth friendly spinal implant systems fall into 3 categories based upon the forces of correction the implants exert on the spine, which are as follows: Distraction-based systems correct spinal deformities by mechanically applying a distractive force across a deformed segment with anchors at the top and bottom of the implants, which commonly attach to the spine, rib, and/or the pelvis. The present examples of distraction-based implants are spine-based or rib-based growing rods, vertical expandable titanium rib prosthesis, and remotely expandable devices. Compression-based systems correct spinal deformities with a compressive force applied to the convexity of the curve causing convex growth inhibition. This compressive force may be generated both mechanically at the time of implantation, as well as over time resulting from longitudinal growth of vertebral endplates hindered by the spinal implants. Examples of compression-based systems are vertebral staples and tethers. Guided growth systems correct spinal deformity by anchoring multiple vertebrae (usually including the apical vertebrae) to rods with mechanical forces including translation at the time of the initial implant. The majority of the anchors are not rigidly attached to the rods, thus permitting longitudinal growth over time as the anchors slide over the rods. Examples of guided growth systems include the Luque trolley and Shilla. CONCLUSIONS: Each system has its benefits and shortcomings. Knowledge of the fundamental principles upon which these systems are based may aid the clinician to choose an appropriate treatment for patients. Having a common language for these systems may aid in comparative research. Vertical expandable titanium rib prosthesis is used with humanitarian exemption. The other devices mentioned in this manuscript are not approved for growing constructs by the Food and Drug Administration and are used off-label.

OBJECTIVES: Professional societies, ethics institutes, and the courts have recommended principles to guide the care of children with life-threatening conditions; however, little is known about the degree to which pediatric care providers are aware of or in agreement with these guidelines. The study's objectives were to determine the extent to which physicians and nurses in critical care, hematology/oncology, and other subspecialties are in agreement with one another and with widely published ethical recommendations regarding the withholding and withdrawing of life support, the provision of adequate analgesia, and the role of parents in end-of-life decision-making. METHODS: Three children's hospitals and 4 general hospitals with PICUs in eastern, southwestern, and southern parts of the United States were surveyed. This population-based sample was composed of attending physicians, house officers, and nurses who cared for children (age: 1 month to 18 years) with life-threatening conditions in PICUs or in medical, surgical, or hematology/oncology units, floors, or departments. Main outcome measures included concerns of conscience, knowledge and beliefs, awareness of published guidelines, and agreement or disagreement with guidelines. RESULTS: A total of 781 clinicians were sampled, including 209 attending physicians, 116 house officers, and 456 nurses. The overall response rate was 64%. Fifty-four percent of house officers and substantial proportions of attending physicians and nurses reported, "At times, I have acted against my conscience in providing treatment to children in my care." For example, 38% of critical care attending physicians and 25% of hematology/oncology attending physicians expressed these concerns, whereas 48% of critical care nurses and 38% of hematology/oncology nurses did so. Across specialties, approximately 20 times as many nurses, 15 times as many house officers, and 10 times as many attending physicians agreed with the statement, "Sometimes I feel we are saving children who should not be saved," as agreed with the statement, "Sometimes I feel we give up on children too soon." However, hematology/oncology attending physicians (31%) were less likely than critical care (56%) and other subspecialty (66%) attending physicians to report, "Sometimes I feel the treatments I offer children are overly burdensome." Many respondents held views that diverged widely from published recommendations. Despite a lack of awareness of key guidelines, across subspecialties the vast majority of attending physicians (range: 92-98%, depending on specialty) and nurses (range: 83-85%) rated themselves as somewhat to very knowledgeable regarding ethical issues. CONCLUSIONS: There is a need for more hospital-based ethics education and more interdisciplinary and cross-subspecialty discussion of inherently complex and stressful pediatric end-of-life cases. Education should focus on establishing appropriate goals of care, as well as on pain management, medically supplied nutrition and hydration, and the appropriate use of paralytic agents. More research is needed on clinicians' regard for the dead-donor rule.

Hepatitis C virus (HCV) is an RNA virus that affects >180 million individuals worldwide with a high propensity for chronic infection. Children with HCV infection differ from adults in several ways including some modes of transmission, rates of clearance, progression of fibrosis, and the duration of potential chronic infection when acquired at birth. Since the discovery of HCV in 1989, there have been significant advances in the understanding of the virology and natural history of chronic HCV infection in children. In addition, there are now several treatment options for children with chronic hepatitis C infection and many new therapies on the horizon. As a consequence, the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition brought together experts in pediatric hepatology to review the available data in children and provide clinicians with approaches to the diagnosis, management, and prevention of HCV infection in children and adolescents. The guideline details the epidemiology and natural history of HCV infection in children, the diagnostic workup, monitoring and treatment of disease, and provides an update on future treatment options and areas of research.
