In contrast to adults, cardiac arrest in infants and children does not usually result from a primary cardiac cause. More often it is the terminal result of progressive respiratory failure or shock, also called an asphyxial arrest. Asphyxia begins with a variable period of systemic hypoxemia, hypercapnea, and acidosis, progresses to bradycardia and hypotension, and culminates with cardiac arrest.1

Another mechanism of cardiac arrest, ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT), is the initial cardiac rhythm in approximately 5% to 15% of pediatric in-hospital and out-of-hospital cardiac arrests;2,–,9 it is reported in up to 27% of pediatric in-hospital arrests at some point during the resuscitation.6 The incidence of VF/pulseless VT cardiac arrest rises with age.2,4 Increasing evidence suggests that sudden unexpected death in young people can be associated with genetic abnormalities in myocyte ion channels resulting in abnormalities in ion flow (see “Sudden Unexplained Deaths,” below).

Since 2010 marks the 50th anniversary of the introduction of cardiopulmonary resuscitation (CPR),10 it seems appropriate to review the progressive improvement in outcome of pediatric resuscitation from cardiac arrest. Survival from in-hospital cardiac arrest in infants and children in the 1980s was around 9%.11,12 Approximately 20 years later, that figure had increased to 17%,13,14 and by 2006, to 27%.15,–,17 In contrast to those favorable results from in-hospital cardiac arrest, overall survival to discharge from out-of-hospital cardiac arrest in infants and children has not changed substantially in 20 years and remains at about 6% (3% for infants and 9% for children and adolescents).7,9

It is unclear why the improvement in outcome from in-hospital cardiac arrest has occurred, although earlier recognition and management of at-risk patients on general inpatient units …

Background Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. Methods Between March 1992 and February 1998, we performed a multicenter trial in which we randomly assigned to suture repair or mesh repair 200 patients who were scheduled to undergo repair of a primary hernia or a first recurrence of hernia at the site of a vertical midline incision of the abdomen of less than 6 cm in length or width. The patients were followed up by physical examination at 1, 6, 12, 18, 24, and 36 months. Recurrence rates and potential risk factors for recurrent incisional hernia were analyzed with the use of life-table methods. Results Among the 154 patients with primary hernias and the 27 patients with first-time recurrent hernias who were eligible for the study, 56 had recurrences during the follow-up period. The three-year cumulative rates of recurren...

A Comparison of Suture Repair with Mesh Repair for Incisional Hernia

Every year, around 830 000 children die from unintentional or "accidental" injuries. The vast majority of these injuries occur in low-income and middle-income countries. However, dozens of prevention strategies and programmes exist. If they were integrated into other child survival programmes and implemented on a larger scale, many of these deaths and much of the injury-related disability could be prevented. Improved health services could also go a long way in reducing the consequences of these injuries.To draw attention to this important public health problem and the possible solutions, WHO and UNICEF have produced this World report on child injury prevention with support from many experts. The report documents the magnitude, risks and prevention measures for child injuries globally –particularly for drowning, burns, road traffic injuries, falls and poisoning. The report makes seven concrete recommendations for policy-makers to improve child injury prevention. This new document is an important policy and advocacy tool for raising attention the issue and guiding action around the world.

World Report on Child Injury Prevention

This book includes detailed information on many of the factors surrounding injuries--the man-made systems and products involved, the groups at greatest risk, and effective ways to protect people from injuries. The circumstances under which injuries occur, the etiologic agents, and the characteristics of the people involved are examined. Chapter 2 summarizes the importance of injuries in relation to other prominent health problems. Subsequent chapters describe injury mortality and, in cases where good population-based studies are available, nonfatal injuries. The analyses in Chapters 3-15 are primarily of injury deaths during 1977-1979, the most recent years for which detailed mortality data were available in mid-1983 for deaths other than those related to motor vehicles. Most of these data were collected by the U.S. Department of Health and Human Services, National Center for Health Statistics (NCHS). Chapters 16-20 summarize data on deaths from motor vehicle-related injuries. Most of these detailed data were obtained from the U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA). Data from the 1980 census provided denominators for the rates throughout the book, except for trendline calculations which were based on interpolations between census years. The purpose of this book is to improve understanding of the nature and magnitude of the injury problem in the United States. Although it includes some discussion of ameliorative approaches, there is no comprehensive coverage of injury research, theory, or prevention, since these have been comprehensively discussed elsewhere. This book is a thorough documentation of the injury problem. Most of the information presented is new, the product of analyses not previously published in any form.

Objective To determine the accuracy and utility of a scoring system designed to allow an objective appraisal of the outcome of hypospadias repair, based on evaluating meatal location, meatal shape, urinary stream, straightness of erection, and the presence and complexity of any complicating urethral fistula.



Patients and methods Twenty patients (median age 23 months) were randomly selected and reviewed at a median of 8.9 months after their hypospadias repair. Two paediatric surgeons, a nurse and one of the child's parents independently assessed each patient using the ‘hypospadias objective scoring evaluation’ (HOSE) system. The results were collated and the level of interobserver variation assessed using the weighted kappa test.



Results The mean weighted kappa was 0.66, indicating good agreement among observers. The level of agreement was highest between surgeon and nurse at 0.70, but remained good between surgeon and parent, at 0.65.



Conclusions Interobserver variation using the HOSE system was minimal, supporting its use as an objective outcome measure after hypospadias surgery, and facilitating an impartial evaluation of operations used in correcting hypospadias.

HOSE : an objective scoring system for evaluating the results of hypospadias surgery

Gastroschisis (GS) continues to increase in frequency, with several studies now reported an incidence of between 4 and 5 per 10,000 live births. The main risk factor would seem to be young maternal age, and it is in this group that the greatest increase has occurred. Whilst various geographical regions confer a higher risk, the impact of several other putative risk factors, including smoking and illicit drug use, may be less important than when first identified in early epidemiological studies. Over 90% of cases of GS will now be diagnosed on antenatal ultrasound, but its value in determining the need for early delivery remains unclear. There would appear no clear evidence for either routine early delivery or elective caesarean section for infants with antenatally diagnosed GS. Delivery at a centre with paediatric surgical facilities reduces the risk of subsequent morbidity and should represent the standard of care. The relative roles of primary closure, staged closure and ward reduction, with or without general anaesthesia, appear less clear with considerable variation between centres in both the use of these techniques and subsequent surgical outcomes. Survival rates continue to improve, with rates well in excess of 90% now routine. The limited long-term developmental data available would suggest that normal or near-normal outcomes may be expected although there remains a need for further studies.
