Pediatric Research. National Institutes of Health support in the 'steady-state' decade, 1983-1993.

OBJECTIVE: To examine the trend in the US Public Health Service's National Institutes of Health (NIH) funding for pediatric research over the last 10 years in terms of dollars expended, grants awarded to pediatrics departments vs other medical school departments, NIH Clinical Research Center support, and the distribution of NIH grants to all medical schools and children's hospitals in the United States. METHODS: Statistical information from the Division of Research Resources of the NIH, the NIH Clinical Research Center office, and the Society for Pediatric Research for the fiscal year 1982-1983 was compared with fiscal year 1992-1993. Inflation-adjusted dollar calculations were used. All numbers reflect total costs (direct plus indirect costs). RESULTS: Research grant support to medical school departments has been stable, increasing only 1% per year in inflation-adjusted dollars to a total of $3.051 billion; while the total number of grants has decreased 12% to 12785 awards. Support for pediatric research increased 91% in inflation-adjusted dollars (to $164 million) during this period, and the number of pediatric research grants increased from 390 to 608 (up 56%). However, the nation's 76 clinical research centers (CRCs) show pediatric clinical research is diminishing. Support for such research has fallen a dramatic 55% in 10 years, despite $5.4 million for pediatric acquired immunodeficiency syndrome (AIDS) clinical trials. There are more pediatric researchers since 1983 (1327-1857), increasing dramatically the number of unfunded pediatric scientists. Disparity of research funding continues between the top research-oriented medical schools (15 of the 126 departments receive 51% of the awards), compared with 72 medical school departments that have 0, 1, or 2 pediatric research grants. Most medical students in the United States will never encounter an NIH-funded pediatric researcher during their medical school training. CONCLUSIONS: Pediatric research has increased its absolute and relative NIH grant support in the last 10 years to a greater degree than all other clinical departments except for psychiatry, neurology, and anesthesiology. The distribution of grants favors a small number of departments and children's hospitals. Clinical pediatric research supported by the NIH has fallen dramatically. In the era of stable NIH funding, pediatric investigators must develop other sources (private funding and industry) for expanding their research activities.

The history of Pediatric Infectious Diseases.

The history of Pediatric Infectious Diseases closely parallels the history of Pediatrics at least until the last century, because historically infections comprised the major causes of childhood morbidity and mortality, as they still do in the developing world. This history reviews developments in the field through the centuries and is written so that it does not overlap the contribution to this series by Baker and Katz entitled 'Childhood Vaccine Development in the United States.' Remarkable descriptions of selected pediatric infections existed long before the invention of printing, and early pediatric texts included many chapters devoted to various infections. Coincident with the establishment of pediatric organizations in America in the late 19th and early 20th Centuries, major attention was focused on diphtheria, infant diarrheal illnesses, tuberculosis, streptococcal infections and their complications, and other pediatric infections, and substantial progress was made. The American Pediatric Society (1888), the American Academy of Pediatrics (1930), the Society for Pediatric Research (1931), and the American Board of Pediatrics (1933) all contributed to the evolution of the discipline of Pediatric Infectious Disease, and numerous leaders of these organizations had significant infectious diseases interests. The establishment of the Pediatric Infectious Diseases Society, the Pediatric Infectious Diseases sub-board, and an accreditation process for training programs, as well as sub-specialty textbooks and journal, further validated the development of this specialty, particularly in North America. The many remaining challenges related to infectious diseases in children (including HIV, emerging infections, antimicrobial resistance, opportunistic infections, and infections in the developing world) insure the future of the specialty. The genomic era of medicine and the tools of molecular biology will lead to new insights into pathogenesis, diagnosis, and treatment of infections. Pediatric Infectious Diseases physicians can celebrate the past triumphs of the discipline and future achievements, all contributing to improved health for children.

Utilization of pediatric hospitals in New York State.

BACKGROUND: Little published information is available regarding the proportion of hospitals that offer pediatric services at specified levels, or the actual utilization of such services. OBJECTIVE: To determine if an existing national accreditation process created for educational purposes identifies hospitals with a distinct utilization pattern, in a sample of pediatric inpatient activity from one state. METHODS: Hospitals in New York State were classified as "pediatric" hospitals according to their sponsorship or major participation with an accredited pediatric residence program. Institutions not affiliated with pediatric residencies were considered to be the "other" hospitals. Data on hospital discharges and interhospital transfers were studied for children from 0 to 14 years old, excluding neonatal Diagnosis-Related Groups. Data were obtained from the New York Statewide Planning and Research Cooperative System for 1996, 1997, and 2000. RESULTS: Sixteen percent of hospitals were considered to be "pediatric" facilities (42 of 257) by study criteria. Annual pediatric inpatient activity per "pediatric" hospital significantly exceeded that in "other" institutions, including hospitalizations (2249 +/- 1284 vs 258 +/- 348), number of interhospital transfers received (153 +/- 88 vs 18 +/- 26), and number of hospitals referring interhospital transfers to each receiving hospital (36 +/- 17 vs 5 +/- 7; mean +/- standard deviation; for each comparison). Statewide, "pediatric" hospitals served two thirds of all hospitalized children and 70% of all children's hospital days. "Pediatric" hospitals cared for 26.5 patients per hospital day, compared with only 2.2 per day at "other" institutions. Although statewide hospitalizations of children fell by 14.3% the proportion of all pediatric hospitalizations served by "pediatric" hospitals increased by 3.8% from 1996 to 2000. CONCLUSIONS: Although intended for educational purposes, hospital affiliation with an accredited pediatric residency program identifies a subgroup of facilities with a distinct utilization pattern, which provides care for the majority of pediatric inpatients, and serves as a resource to other hospitals.

Pediatric defibrillation doses often fail to terminate prolonged out-of-hospital ventricular fibrillation in children.

BACKGROUND: The recommended dose for pediatric defibrillation is 2 J/kg, based on animal studies of brief duration ventricular fibrillation (VF) and a single pediatric study of short duration in-hospital VF. In a piglet model of out-of-hospital (prolonged) cardiac arrest, this recommended dose was usually ineffective at terminating VF. We, therefore, hypothesized that pediatric dose defibrillation may be less effective for prolonged out-of-hospital pediatric VF. METHODS: We evaluated retrospectively all cardiac arrests in children less than 13 years old in Tucson from November 1998 to April 2003, with special attention to all children in ventricular fibrillation. We determined the rate of ventricular fibrillation termination after pediatric dose shocks in this cohort, and compared this rate with a published historical pediatric in-hospital defibrillation control group. A pediatric dose shock was defined as 2 J/kg (+/-10 J). All shocks in both groups were provided as monophasic damped sinusoidal waveforms. RESULTS: Thirteen of 151 (9%) children with out-of-hospital cardiac arrest had documented VF. Eleven children received a total of 14 pediatric dose shocks. The median minimum untreated dispatch-to-shock time in unwitnessed arrest or collapse-to-shock in witnessed arrest for those 11 children was 11 min (interquartile range 25-75%; 9-15.5 min). Seven of the 14 pediatric dose shocks terminated the VF (six to asystole, one to pulseless electrical activity). Nine children (68%) died in the emergency department and four (31%) in the pediatric intensive care unit; none survived to hospital discharge. Failure to terminate VF after a pediatric dose shock in this study group with prolonged out-of-hospital ventricular fibrillation was substantially more common than the previously reported in-hospital data (7/14 versus 5/57; OR 10.4; 95% CI 2.6-42; P=0.001). CONCLUSIONS: Termination of VF after a pediatric defibrillation dose is substantially worse for prolonged pediatric out-of-hospital VF cardiac arrest compared with in-hospital (short duration) ventricular fibrillation. The optimal pediatric defibrillation dose for prolonged VF is not known.

Family pediatrics: report of the Task Force on the Family.

WHY A TASK FORCE ON THE FAMILY? The practice of pediatrics is unique among medical specialties in many ways, among which is the nearly certain presence of a parent when health care services are provided for the patient. Regardless of whether parents or other family members are physically present, their influence is pervasive. Families are the most central and enduring influence in children's lives. Parents are also central in pediatric care. The health and well-being of children are inextricably linked to their parents' physical, emotional and social health, social circumstances, and child-rearing practices. The rising incidence of behavior problems among children attests to some families' inability to cope with the increasing stresses they are experiencing and their need for assistance. When a family's distress finds its voice in a child's symptoms, pediatricians are often parents' first source for help. There is enormous diversity among families-diversity in the composition of families, in their ethnic and racial heritage, in their religious and spiritual orientation, in how they communicate, in the time they spend together, in their commitment to individual family members, in their connections to their community, in their experiences, and in their ability to adapt to stress. Within families, individuals are different from one another as well. Pediatricians are especially sensitive to differences among children-in their temperaments and personalities, in their innate and learned abilities, and in how they view themselves and respond to the world around them. It is remarkable and a testament to the effort of parents and to the resilience of children that most families function well and most children succeed in life. Family life in the United States has been subjected to extensive scrutiny and frequent commentary, yet even when those activities have been informed by research, they tend to be influenced by personal experience within families and by individual and cultural beliefs about how society and family life ought to be. The process of formulating recommendations for pediatric practice, public policy, professional education, and research requires reaching consensus on some core values and principles about family life and family functioning as they affect children, knowing that some philosophic disagreements will remain unresolved. The growing multicultural character of the country will likely heighten awareness of our diversity. Many characteristics of families have changed during the past 3 to 5 decades. Families without children younger than 18 years have increased substantially, and they are now the majority. The average age at marriage has increased, and a greater proportion of births is occurring to women older than 30 years. Between 1970 and 2000, the proportion of children in 2-parent families decreased from 85% to 69%, and more than one quarter (26%) of all children live with a single parent, usually their mother. Most of this change reflects a dramatic increase in the rate of births to unmarried women that went from 5.3% in 1960 to 33.2% in 2000. Another factor in this change is a slowly decreasing but still high divorce rate that is roughly double what it was in the mid-1950s. Family income is strongly related to children's health, and the financial resources that families have available are closely tied to changes in family structure. Family income in real dollars has trended up for many decades, but the benefits have not been shared equally. For example, the median income of families with married parents has increased by 146% since 1970, but female-headed households have experienced a growth of 131%. More striking is that in 2000, the median income of female-headed households was only 47% of that of married-couple families and only 65% of that of families with 2 married parents in which the wife was not employed. Not surprising, the proportion of children who live in poverty is approximately 5 times greater for female-headed families than for married-couple families. The comped families than for married-couple families. The composition of children's families and the time parents have for their children affect child rearing. Consequent to the increase in female-headed households, rising economic and personal need, and increased opportunities for women, the proportion of mothers who are in the workforce has climbed steadily over the past several decades. Currently, approximately two thirds of all mothers with children younger than 18 years are employed. Most families with young children depend on child care, and most child care is not of good quality. Reliance on child care involves longer days for children and families, the stress imposed by schedules and created by transitions, exposure to infections, and considerable cost. An increasing number and proportion of parents are also devoting time previously available to their children to the care of their own parents. The so-called "sandwich generation" of parents is being pulled in multiple directions. The amount and use of family time also has changed with a lengthening workday, including the amount of commuting time necessary to travel between work and home, and with the intrusion of television and computers into family life. In public opinion polls, most parents report that they believe it is more difficult to be a parent now than it used to be; people seem to feel more isolated, social and media pressures on and enticements of their children seem greater, and the world seems to be a more dangerous place. Social and public policy has not kept up with these changes, leaving families stretched for time and stressed to cope and meet their responsibilities. What can and what should pediatrics do to help families raise healthy and well-adjusted children? How can individual pediatricians better support families? FAMILY PEDIATRICS: The American Academy of Pediatrics (AAP) Board of Directors appointed the Task Force on the Family to help guide the development of public policy and recommend how to assist pediatricians to promote well-functioning families (see Appendix). The magnitude of the assigned work required task force members to learn a great deal from research and researchers in the fields of social and behavioral sciences. A review of some critical literature was completed by a consultant to the task force and accompanies this report. That review identified a convergence of pediatrics and research on families by other disciplines. The task force found that a great deal is known about family functioning and family circumstances that affect children. With this knowledge, it is possible to provide pediatric care in a way that promotes successful families and good outcomes for children. The task force refers to that type of care as "family-oriented care" or "family pediatrics" and strongly endorses policies and practices that promote the adoption of this 2-generational approach as a hallmark of pediatrics. During the past decade, family advocates have successfully promoted family-centered care, "the philosophies, principles and practices that put the family at the heart or center of services; the family as the driving force." Most pediatricians report that they involve families in the decision making regarding the health care of their child and make an effort to understand the needs of the family as well as the child. Family pediatrics, like family-centered care, requires an active, productive partnership between the pediatrician and the family. But family pediatrics extends the responsibilities of the pediatrician to include screening, assessment, and referral of parents for physical, emotional, or social problems or health risk behaviors that can adversely affect the health and emotional or social well-being of their child. FAMILY CONTEXT OF CHILD HEALTH: The power and importance of families to children arises out of the extended duration for which children are dependent on adults to meet their basic needs. Children's needs for which only a family can provide include social support, socialization, and coping and life skills. Their self-esteem grows from being cared for, loved, and valued and feeling that they are part of a social unit that shares values, communicates openly, and provides companionship. Families transmit and interpret values to their children and often serve as children's connection to the larger world, especially during the early years of life. Although schools provide formal education, families teach children how to get along in the world. Often, efforts to discuss families and make recommendations regarding practice or policy stumble over disagreements about the definition of a family. The task force recognized the diversity of families and chose not to operate from the position of a fixed definition. Rather, the task force, which was to address pediatrics, decided to frame its deliberations and recommendations around the functions of families and how various aspects of the family context influence child rearing and child health. One model of family functioning that implicitly guided the task force is the family stress model (Fig 1). Stress of various sorts (eg, financial or health problems, lack of social support, unhappiness at work, unfortunate life events) can cause parents emotional distress and cause couples conflict and difficulty with their relationship. These responses to stress then disrupt parenting and the interactions between parent and child and can lead to short-term or lasting poor outcomes. The earlier these events transpire and the longer that the disruption lasts, the worse the outcomes for children. The task force favors efforts to encourage and support marriage yet recognizes that every family constellation can produce good outcomes for children and that none is certain to yield bad ones.

Lead screening practices of pediatric residents.

OBJECTIVES: As part of their training, pediatric residents provide primary care services to young children, including youngsters who may have elevated blood lead levels. We set out to (1) determine the percentage of pediatric residents who screen children for elevated blood lead levels according to the guidelines of the Centers for Disease Control and Prevention and the American Academy of Pediatrics; (2) assess the likelihood of lead screening by residents based on demographic and practice-setting characteristics; and (3) compare the attitudes of residents who report that they are universal screeners, selective screeners, or nonscreeners. DESIGN: Confidential, cross-sectional survey of a nationally representative sample of pediatric residents conducted as part of the American Academy of Pediatrics 28th Periodic Survey of Fellows. SUBJECTS: One hundred forty-three responding pediatric residents (51% response rate). RESULTS: Seventy-five percent of pediatric residents reported screening all patients aged 9 to 36 months for elevated blood lead levels, 21% reported screening some, and 4% reported screening none. Pediatric residents who cared for patients in urban settings were more likely to report screening patients for elevated blood lead levels than were pediatric residents who cared for patients in suburban or rural settings (100% vs 73%; P < .001) and pediatric residents in the Northeast were more likely to report screening universally than were residents in the rest of the country (93% vs 63%; P < .001). Overall, pediatric residents who reported screening patients universally were more likely to believe that the benefits of screening outweigh the costs than were residents who reported screening patients selectively (67% vs 17%; P < .001). CONCLUSIONS: Most pediatric residents reported that they screened patients for elevated blood lead levels, either universally or selectively. Nevertheless, the screening practices of pediatric resident and their opinions concerning the relative benefits and costs of lead screening largely reflect the areas of the country and the practice settings in which they had their primary care experiences.

Creating and curating a pediatric radiology digital library to make the internet a useful reference tool for the radiologist.

BACKGROUND: To practice pediatric radiology optimally, radiologists need convenient access to organized and authoritative pediatric radiology information. The Internet has the potential for offering such convenient access, but the majority of information on it is poorly organized and of questionable authority. OBJECTIVE: The goal of this project was to create and curate a pediatric radiology digital library that will make the Internet a useful reference tool for the radiologist at the point-of-care. MATERIALS AND METHODS: A pediatric radiology digital library containing organized and authoritative pediatric radiology information from the Internet was created and has three components : (1) PediatricRadiology.com (http://pediatricradiology.com)--a catalog of pediatric radiology Web sites; (2) The MetaTextbook of Pediatric Radiology (http://www. vh.org/Providers/TeachingFiles/MetatextbookPedRad/MetaTBP edRad.html)--a catalog of pediatric radiology teaching file cases on the Internet; and (3) Paediapedia (http://www.vh. org/Providers/TeachingFiles/PAP/PAPHome.html)--an imaging encyclopedia of pediatric disease. The pediatric radiology digital library is curated regularly. RESULTS: Over 7 months, 223,689 pages of information were read and 26,972 images were viewed in the pediatric radiology digital library by 69,866 individual users, with 20% of the users from outside the United States. CONCLUSION: Creating a pediatric radiology digital library that identifies and organizes authoritative pediatric radiology information and makes it conveniently available can allow radiologists to use the Internet productively as a reference tool.

Estimated use of a pediatric emergency department observation unit.

STUDY OBJECTIVE: To estimate the use of a pediatric ED observation unit, including the number of anticipated admissions per 10,000 pediatric ED visits per year and the distribution of those admissions by age group, by month, and by time of day. METHODS: Hospital and ED computer records on all ED patients younger than 18 years who were seen during a 2-year period were abstracted for diagnostic, demographic, and time-flow data. We retrospectively reviewed the charts of patients admitted to the hospital and discharged within 24 hours to determine whether discharge in less than 24 hours could have been anticipated and whether the patient could have been cared for in a pediatric ED observation unit. To refine the estimate, we also reviewed the ICD-9 discharge diagnoses of patients who were not admitted to the hospital but spent more than 6 hours in the pediatric ED. RESULTS: Of 29,667 pediatric ED visits in a 2-year period, 2,940 (10%) resulted in admission. Of 626 patients discharged in less than 24 hours, only 410 met the anticipation and pediatric ED observation unit level of care criteria. Patients younger than 4 years represented 43% of potential observation unit patients; those aged 16 and 17 years represented 15%. Potential use of an observation unit varied throughout the year. Admission occurred between 3 and 11:59 PM in 60% of the patients. Only 20% of the 176 patients who were not admitted to the hospital but spent more than 6 hours in the pediatric ED were estimated to be candidates for a pediatric ED observation unit. CONCLUSION: On the basis of these data, approximately 150 patients per 10,000 each year who visit the University of Virginia pediatric ED would be likely to use an observation unit. Staffing and facility use would be seasonally uneven and would be required during the busiest part of the day. Furthermore, even in a pediatric ED large enough to admit 365 pediatric ED observation unit patients each year, random daily variation in demand means that a single bed would be inadequate 25% of the time and empty 37% of the time. Optimal use of even a single-bed pediatric ED observation unit would not occur until pediatric ED census exceeded 30,000 to 40,000 visits annually.

Growth and development of pediatric research.

Pediatric research may be entering a period of failure to thrive. This is despite impressive scientific achievements, significant financial benefits, intriguing unanswered questions and a rewarding life for the pediatric researcher. Many of the difficulties are financial and situational, including small departments and divisions, few pediatric research mentors, impecunious pediatric hospitals and services, ethical constraints on pediatric research and competing responsibilities. Grants to pediatric departments represent about 3% of the total NIH research project support. The two largest federal programs supporting Pediatric Research are the Clinical Research Center (CRC) program (20% of an +28,000,000/yr budget) and the National Institutes of Child Health and Human Development (17% of a +123,000,000/yr budget). There are 75 CRCs of which 60 admit children; 10 CRCs are in children's hospital and 6 other CRCs have a clear pediatric focus. Pediatric Departments receive 3% of NIH funds; this represents 10% of funds to clinical departments. By contrast medicine departments receive 17% of NIH funds (47% of funds to clinical departments). NIH research support to pediatrics (+82,000,000/yr) is centered in a few large departments; 14 pediatric departments receive 343 of the 572 NIH grants (60%). By contrast, 66 of 120 pediatric departments have no (45) or 1 (21) NIH grants. Obstacles are identified and suggestions are offered for future (students and residents), beginning (fellows and assistant professors), established (associate and full professors) and women pediatric researchers.

A short history of pediatric endocrinology in North America.

Pediatric endocrinology evolved as a subspecialty from the era of biochemical and metabolic clinical investigation led by John Howland, Edwards Park, and James Gamble at Johns Hopkins; Allan Butler at Boston University and Harvard University; Daniel Darrow at Yale University; and Irving McQuarrie at the University of Rochester and the University of Minnesota during the early 20th century. The father of the new subspecialty was Lawson Wilkins, a private pediatric practitioner in Baltimore, Maryland, who was invited by Dr. Edwards Park to establish an endocrine clinic at the Harriet Lane Home at Johns Hopkins in 1935. Dr. Wilkins managed his practice and the clinic until 1946, when, at the age of 52, he accepted a full-time position at the University. Dr. Nathan Talbot was invited to develop a pediatric endocrine clinic at Massachusetts General Hospital by Allan Butler in 1942. These units and their associated subspecialty training programs during the 1950s and 1960s provided the large majority of the second-generation pediatric endocrinologists who went on to establish endocrine subspecialty programs in university medical centers in North America as well as Europe and South America. Diabetes as a clinical pediatric discipline evolved in parallel from the early clinics of Elliott Joslin and Priscilla White in Boston, M.C. Hardin and Robert Jackson at the University of Iowa, George Guest at the University of Cincinnati Children's Hospital, and Alex Hartman at the St. Louis Children's Hospital. The Lawson Wilkins Pediatric Endocrine Society was founded in 1971, and the Council on Diabetes and Youth was established within the American Diabetes Association in 1980. Medical and economic factors led to increasing integration of pediatric diabetes and general endocrine care and training, and diabetes care now is a major activity within the subspecialty of pediatric endocrinology. The growth of pediatric endocrinology in North America has paralleled the growth of academic medicine during the past half-century. In 2002, there were 72 training programs in North America: 65 in the United States and seven in Canada. The endocrinology sub-board of the American Board of Pediatrics was established in 1978 to certify training and competence in endocrinology, including diabetes. By 2002, the board had certified 927 pediatric endocrinologists. Pediatric endocrine subspecialists during the past half-century have contributed major advances in our understanding of the ontogeny of endocrine systems and the diagnosis and treatment of fetal-perinatal endocrine disorders; newborn screening for endocrine and metabolic disorders; the physiology and therapies for disorders of sexual differentiation and pubertal maturation; the development of anthropometric standards for childhood growth and development; the characterization and physiology of hormone systems, including receptors and hormone actions; the molecular genetics of a number of congenital endocrine disorders and heritable endocrine diseases; development of pediatric endocrine diagnostics and reference standards; the pathophysiology and management of autoimmune endocrine disease; and development of a growing armamentarium of therapeutic agents for treatment of endocrine and metabolic diseases.

Patient visits to a national practice-based research network: comparing pediatric research in office settings with the National Ambulatory Medical Care Survey.

OBJECTIVE: Our objective with this study was to assess the extent to which patients who are seen by practitioners in Pediatric Research in Office Settings, a national primary care practice-based research network, are representative of those who are seen in ambulatory office-based pediatric primary care in the United States. METHODS: Pediatric Research in Office Settings patient data were collected from the offices of 57 randomly selected network practitioners as part of an Agency for Healthcare Research and Quality-funded effort to describe primary care visits and replicate the National Ambulatory Medical Care Survey in primary care practice-based research networks. These data were from 1706 randomly selected pediatric patient visits that occurred between March and June 2002. National comparison data were 948 randomly selected pediatric patient visits that occurred between March and June 2000 in the offices of the 33 primary care pediatric practitioners who had participated in the National Ambulatory Medical Care Survey. The groups were compared on patient demographics (age, gender, race, ethnicity, and socioeconomic status, as represented by Medicaid status), visit characteristics (percentages of patients referred, practitioner designation of visit as acute versus nonacute, and continuity of care), the top patient/parent-articulated reasons for visit, and the top practitioner diagnoses. RESULTS: Comparisons revealed substantial similarities between Pediatric Research in Office Settings and national data, including gender, ethnicity, socioeconomic status, and visit characteristics. Differences were noted for age and race, with Pediatric Research in Office Settings children approximately 1 year older and comprising a significantly lower proportion of black patients than their National Ambulatory Medical Care Survey counterparts. Although the top 6 reasons that were articulated by parents for outpatient visits in the 2 groups were remarkably similar in rank order and proportions, there were overall differences, mostly attributable to a larger number of the "other" category in the Pediatric Research in Office Settings cases. There were no significant differences among the top 5 practitioner visit diagnoses between the Pediatric Research in Office Settings and National Ambulatory Medical Care Survey data. CONCLUSIONS: The Pediatric Research in Office Settings patient population is reasonably representative of patients who are seen in US ambulatory office-based pediatric primary care practices; therefore, the Pediatric Research in Office Settings is an appropriate laboratory for studies of care in such settings.

The effect of a curfew on pediatric out-of-hospital EMS responses.

OBJECTIVE: The purpose of a curfew is to decrease the amount of crime inflicted on minors during the late hours of the night. On June 1, 1994, a city curfew was instituted in New Orleans, requiring all persons 17 years of age or younger to be off the streets from 9 PM to 6 AM Sunday through Thursday, and from 11 PM to 6 AM on Friday and Saturday. This study evaluated the effect of the curfew on emergency medical services (EMS) transports for patients who were 17 years old or younger (pediatric). METHODS: Data from all pediatric transports were included from the months before (5/94) and after (6/94) the institution of the curfew, and from the same two months one year earlier (5/93 and 6/93). A chi-square test was used to evaluate comparisons. RESULTS: The city EMS transports 48,000 patients per year in a one-tiered system (paramedic only) that acts as the sole provider of emergency EMS transport in the city. Approximately 10% of all transports are pediatric, and 40% of the pediatric transports are for trauma. A total of 1,642 transports were found that fit the inclusion criteria. In May 1993, there were 415 total pediatric transports; 234 were pediatric trauma. In June 1993, there were 406 total pediatric transports; 250 were pediatric trauma. In May 1994, there were 447 total pediatric runs; 243 were pediatric trauma. During the postcurfew month, June 1994, there were a significant decrease in pediatric transports to 370 (p < 0.01) and a significant decrease in pediatric trauma transport to 189 (p < 0.01). CONCLUSION: The institution of a curfew may lead to a drop in pediatric EMS runs during curfew hours. Another value of the curfew may be in the secondary effects of the curfew in preventing childhood injury during noncurfew hours.

Measurements of total plasma nitrite and nitrate in pediatric patients with the systemic inflammatory response syndrome.

OBJECTIVES: The systemic inflammatory response syndrome (SIRS) is typified by the presence of fever, hemodynamic changes, and end organ dysfunction. Endothelial cell activation leads to overproduction of nitric oxide, which results in sustained vasodilation and hypotension. This study was undertaken to determine the sensitivity, specificity, and positive and negative predictive values of plasma nitrite/nitrate measurements in identifying patients with clinical characteristics of SIRS, as defined by criteria based on physician diagnosis. DESIGN: Prospective cohort study with consecutive sampling of patients. SETTING: Tertiary, multidisciplinary, pediatric intensive care unit (ICU) at Children's Hospital of Wisconsin. PATIENTS: Patients were divided into five groups. There were 16 pediatric controls undergoing elective surgery and 177 pediatric ICU patients without and 46 pediatric ICU patients with physician-diagnosed sepsis, septic shock, SIRS, or sepsis syndrome documented in the medical record (all considered physician-diagnosed sepsis). The 223 pediatric ICU patients included 195 pediatric ICU patients not meeting and 28 pediatric ICU patients meeting predetermined physiologic criteria for SIRS (considered criteria-based sepsis). INTERVENTIONS: Blood samples were obtained for quantitative nitrite/nitrate analysis at the time of admission to the pediatric ICU and daily until discharge. MEASUREMENTS AND MAIN RESULTS: Mean plasma nitrite/nitrate concentrations in the controls were 34.5 +/- 12 microM (95th percentile 54 microM). In pediatric ICU patients without and with physician-diagnosed sepsis, mean plasma nitrite/nitrate concentrations were 39 +/- 24 microM (p > .05 compared with controls) and 127 +/- 91 microM (p < .0001 compared with both controls and patients without physician-diagnosed sepsis), respectively. In pediatric ICU patients without and with criteria-based sepsis, the mean total plasma nitrite/nitrate concentrations were 56 +/- 59 microM (p = .008 compared with controls) and 80 +/- 64 microM (p = .003 compared with patients without criteria-based sepsis), respectively. The ability of plasma nitrite/nitrate > 54 microM to identify patients with physician-diagnosed sepsis is characterized as follows: 87% sensitivity, 77% specificity, 50% positive predictive value, and 96% negative predictive value. The ability of plasma nitrite/nitrate > 54 microM to identify patients with criteria-based sepsis is characterized as follows: 61% sensitivity, 68% specificity, 21% positive predictive value, and 92% negative predictive value. CONCLUSIONS: Clinical diagnosis of SIRS is strongly associated with increased total plasma nitrite/nitrate concentrations in pediatric patients in the pediatric ICU. Many patients with increased nitrite/nitrate concentrations have inflammation without having a clinical diagnosis of SIRS. Our data suggest that increased plasma nitrite/nitrate concentrations are the standard for identifying patients with inflammation in the pediatric ICU.

Identification and management of intrathecal baclofen pump complications: a comparison of pediatric and adult patients.

OBJECT: Intrathecal baclofen therapy is an effective means of treating intractable spasticity and dystonia in the pediatric and adult population. The authors present a review of complications encountered in a series of 314 pump and catheter-related procedures. The identification and management of these complications will be reviewed. The authors will also identify populations that may be at increased risk for complications. METHODS: A retrospective review was performed of all procedures undertaken during the last 5 years by two surgeons at the authors' institution. Postoperative complications were reviewed. A total of 314 surgical procedures (226 pediatric and 88 adult) were performed in 195 pediatric and adult patients. This included 171 new pump and catheter implants (116 pediatric and 55 adult), 26 elective pump replacements due to end of battery life (15 pediatric and 11 adult), five elective pump repositionings per physiatrist request (three pediatric and two adult), 14 elective catheter repositionings (10 pediatric and four adult), and two normal pediatric catheter explorations. Surgical procedures for complication management included seven pump revisions (five pediatric and two adult), 48 catheter revisions (38 pediatric and 10 adult), and 41 wound revisions (37 pediatric and four adult). The majority of adult pumps were implanted subdermally, whereas in pediatric patients they were placed subfascially. In general, intrathecal catheters were placed under fluoroscopic guidance with the catheter tip placed at T-1 to T-2 for spastic quadriplegia, T-6 to T-10 for spastic diplegia, and midcervical for dystonia. No significant intraoperative complications were encountered. Overall, there was a statistically significantly higher percentage of procedures for overall complication management and wound complication management in pediatric patients compared with adult patients. CONCLUSIONS: Intrathecal baclofen therapy is a highly effective treatment option for patients with medically refractory spasticity. The catheter, pump, and wound are subject to numerous complications both at the time of implantation and throughout the life of the implanted system. Careful technique, close observation, and aggressive evaluation and correction of problems can reduce the incidence and severity of the complications when they occur.

History of German pediatric cardiology.

Due to the isolation of German medicine in World War II accompanied by the destruction of many hospitals, German pediatricians did not show any serious interest in the treatment of children with congenital heart diseases, nor did they take notice of the progress achieved by Helen Taussig, Alfred Blalock and other cardiologists and surgeons in the western world. This problem was even worse in East Germany. Only a few German internists and forward-looking surgeons were able and ready to take care of this group of principally operable children in places like Bonn/Düsseldorf, Marburg/Munich, Berlin, and Hamburg. However, in the early 1950s some directors of pediatrics at university hospitals--largely motivated by the cardiac surgeons--allowed or even encouraged younger colleagues to concentrate on pediatric cardiology and to begin application of heart catheterization and angiocardiography. In 1960 a group of colleagues interested in pediatric cardiology met for the first time in Frankfurt and became the nucleus of the future "working group" (1969) and finally the "German Society of Pediatric Cardiology" (1974). By 1972 pediatric cardiology had been approved as an independent (sub)specialty. Colleagues and friends from surrounding countries (Austria, Great Britain, Sweden, Switzerland, and the Netherlands) and also from the US and some eastern countries were either members or regular guests during or between the meetings. Pediatric cardiology is now represented in Germany by specialized practitioners, trainees and assistants who work in both community and university hospitals, and in specialized departments. Due to the foresightedness of the Chief of Pediatrics, Prof. G. Joppich, the first Chair of Pediatric Cardiology was founded in Göttingen in 1960 under the direction of A. Beuren. Another model of interdisciplinary cooperation between pediatric cardiologists, bioengineers, mathematicians and computer scientists was established in Kiel in 1966. In other places pediatric and adult cardiologists were brought together in "Heart Centers" with cardiovascular surgeons. The first of these Heart Centers was founded in 1974 in Munich under the directorship of K. Bühlmeyer and comparable centers were later established in Bad Oeynhausen (1985) and Berlin (1986). Following reunification in 1990, pediatric cardiologists from the east and west came together. Thus, within the last three to four decades German pediatric cardiology gradually caught up with international standards and in some fields of cardiovascular research even assumed a leading role. The care of the growing numbers of surviving patients with congenital heart disease has become a new challenge that has to be met by experienced cardiologists. To maintain the level of competence, future activities should however, not only concentrate on the optimal care of patients with congenital heart disease but also be responsible for cardiovascular research.

Demand outstrips supply of US pediatric dermatologists: results from a national survey.

BACKGROUND: The US pediatric dermatology workforce was last examined in 1986 when limited employment opportunity was found. OBJECTIVE: We sought to re-examine pediatric dermatology workforce issues. METHODS: US dermatology chairpersons and residency program directors were surveyed for: (1) agreement with pediatric dermatology workforce statements; and (2) pediatric dermatology faculty and fellow numbers. RESULTS: Respondents agreed that having a pediatric dermatologist or dermatologists on faculty is important, and that a shortage of pediatric dermatologists exists, but did not agree that increasing pediatric dermatology training requirements will increase this shortage. Almost half of the programs (45/94) employed a full-time pediatric dermatologist, and 24 programs had currently been recruiting a pediatric dermatologist for more than 1 year. Only 6 pediatric dermatology fellows were in training. CONCLUSION: Given that open pediatric dermatology faculty positions greatly exceed the number of fellows in training and that formal training requirements will be increasing, the shortage of pediatric dermatologists will likely continue.

The impact of pediatric surgery training on the attitudes and practice patterns of general surgeons.

In order to evaluate how experience in pediatric surgery during residency training affects attitudes and practice patterns of general surgeons, questionnaires were sent to the 51 residents who graduated from our general surgical residency program since the establishment of a Section of Pediatric Surgery in 1974. There were 51 respondents (100%) of whom 50 were male and 1 female. Three were pediatric surgeons and their responses to the questionnaire were not included in the analysis. During the past year, 29 of the respondents had performed from 2 to 55 pediatric operations, with a mean of 23.7. Most of these were herniorrhaphies, appendectomies, and sub-specialty cases. Thirty-two of the 48 respondents referred most pediatric cases to a board certified pediatric surgeon nearby. Ninety-two percent of the respondents indicated that pediatric surgery rotations were of great value in their training (6.3 mean response on a scale of 7) and 92% felt that pediatric surgery was a necessary part of a general surgery training program. Respondents had a mean exposure of 1.8 mo to pediatric surgery as junior residents, and 2.1 mo as senior residents; 90% felt that their operative experience was good to excellent (5.5 mean on a scale of 7). Most respondents felt qualified to do many more pediatric procedures than they actually performed; however, their perception was that these cases were best done by fully trained pediatric surgeons. The 51 graduates of our general surgical residency program considered pediatric surgery an important factor in the development of their technical skills and surgical judgment.

Pediatric surgeons on the Internet: a multi-institutional experience.

An estimated 24 million people, or 11% of the North American population over 16 years of age, use the Internet. An estimated 40% of households have computers, and 37 million people have Internet access. The experience of three pediatric surgery Internet sites are reviewed to evaluate current practices and future potential of the Internet to practicing pediatric surgeons. The sites reviewed are the Pediatric Surgery Bulletin Board System (BBS), the Pediatric Surgery List Server, and the Pediatric Surgery Website. Statistics were collected at each site to characterize the number of users, traffic load, topics of interest, and times of peak use. There are currently 79 subscribers to the Pediatric Surgery BBS and 100 subscribers to the Pediatric Surgery List Server. The average user of the BBS is a young man who has placed an average of 52 calls to the BBS since joining. There have been 1413 Internet electronic mail messages sent. Twenty-five percent of the traffic has been related to clinical problems and 5% to research, teaching, and career issues. Traffic at this site has been increasing exponentially with most of the dialogue concentrated on clinical issues and problem cases. In a 3-month period the Pediatric Surgery Website received 16,270 hits. The most commonly accessed areas include an electronic mail directory, case studies, the job board, information on the pediatric surgical residency, and information on upcoming meetings. Pediatric surgeons are exploring the Internet and using available pediatric surgery resources. The scope of professional information available to pediatric surgeons on the Internet is still limited but is increasing rapidly. The Internet will impact the way physicians practice medicine through education and communication.
