Review Case Reports Multicenter Study
Fatal malignant hyperthermia-like syndrome with rhabdomyolysis complicating the presentation of diabetes mellitus in adolescent males.
This report describes a new fatal syndrome observed in adolescent males at the initial presentation of diabetes mellitus. The features include hyperglycemic hyperosmolar coma complicated by a malignant hyperthermia-like picture with fever, rhabdomyolysis, and severe cardiovascular instability. ⋯ The underlying etiology of this syndrome remains unclear. Possibilities include an underlying metabolic disorder such as a fatty acid oxidation defect, an unrecognized infection, exposure to an unknown toxin, or a genetic predisposition to malignant hyperthermia. Evaluation for all these possibilities and empiric treatment with dantrolene should be considered for this type of patient until this syndrome is better characterized.

Multicenter Study Comparative Study
Perinatal outcomes in two dissimilar immigrant populations in the United States: a dual epidemiologic paradox.
Previous studies have addressed perinatal outcomes in Hispanic, black, and white non-Hispanic women and demonstrated that although foreign-born Mexican American women have many demographic and socioeconomic risk factors, their rates of low birth weight (LBW) infants and infant mortality are similar to those of white women. This phenomenon has been termed an epidemiologic paradox. There have been no population-based studies on women of Asian Indian origin, a relatively new, highly educated, and affluent immigrant group that has been reported to have a high rate of LBW infants. The objective of this study was to define the sociodemographic risk profile and perinatal outcomes in women of Asian Indian birth and to compare these outcomes to foreign-born Mexican American and US-born black and white women. ⋯ Despite their high socioeconomic status and early entry into care, foreign-born Asian Indian women have a paradoxically higher incidence of LBW infants and fetal deaths when compared with US-born whites. Factors that protect from giving birth to an LBW infant in white women were not protective among Asian Indian women. Current knowledge regarding factors that confer a perinatal advantage or disadvantage is unable to explain this new epidemiologic paradox. These findings highlight the need for additional research into both epidemiologic and biological risk factors that determine perinatal outcomes.

Multicenter Study
Platelet count and sepsis in very low birth weight neonates: is there an organism-specific response?
Thrombocytopenia is commonly observed in very low birth weight (VLBW) neonates with sepsis. Specific platelet responses to different infectious agents have not been extensively characterized. The objectives of this study were to examine platelet counts and platelet indices in preterm neonates with culture-proven sepsis to determine if there are organism-specific platelet responses. ⋯ In our population of VLBW infants, sepsis is frequently associated with thrombocytopenia and an elevation in MPV. However, fungal and Gram-negative pathogens are associated with a lower platelet count and more prolonged thrombocytopenia compared with Gram-positive pathogens. We conclude that common pathogens causing sepsis have different effects on platelet kinetics.

Multicenter Study Comparative Study
Patient safety events during pediatric hospitalizations.
Our objective was to describe potential patient safety events for hospitalized children, using the patient safety indicators (PSIs), and examine associations with these events. ⋯ The prevalence of birth trauma and other potential patient safety events for hospitalized children is high and comparable to hospitalized adults. These events are associated with increased length of stay, in-hospital mortality, and total charges. Associated factors differ significantly for birth trauma compared with other PSI events. Institutional application of the PSIs may be useful to identify processes of care that warrant further evaluation as the health care industry tackles the problem of patient safety, particularly for children.

Rates of pediatric injuries by 3-month intervals for children 0 to 3 years of age.
Mortality and morbidity data on childhood injury are used to construct developmentally appropriate intervention strategies and to guide pediatric anticipatory counseling on injury prevention topics. Effective anticipatory guidance depends on detailed injury data showing how risks change as children develop. Conventional age groupings may be too broad to show the relationship between children's development and their risk of various causes of injury. Previous studies revealed differences in overall rates and specific causes of injury by year of age. However, single year of age rates for children younger than 4 years may not reflect the variations in risk as a result of rapid developmental changes. This study was designed to analyze injury rates for children younger than 4 years by quarter-year intervals to determine more specifically the age period of highest risk for injury and for specific causes. ⋯ We departed from usual groupings of E-codes and devised groupings that would be reflective of age-related developmental characteristics. Differences in rates by narrow age groups for young children can be related to developmental achievements, w can be related to developmental achievements, which place the child at risk for specific causes of injury. We found marked variability in both rates and leading causes of injury by 3-month interval age groupings that were masked by year of age analyses. Children aged 15 to 17 months had the highest overall injury rate before age 15 years. This coincides with developmental achievements such as independent mobility, exploratory behavior, and hand-to-mouth activity. The child is able to access hazards but has not yet developed cognitive hazard awareness and avoidance skills. A remarkable finding was the high rate of battering injury among infants 0 to 5 months, suggesting the need to address potential child maltreatment in the perinatal period. Poisoning was the second major leading cause of injury; more than two thirds were medication. Cultural factors may influence views of medications, storage practices, use of poison control system telephone advice, and risk of toddler poisoning. The pedestrian injury rate doubled between 12 and 14 months and 15 and 17 months and exceeded motor vehicle occupant injury rates for each 3-month interval from 15 to 47 months. Pedestrian injury has not received sufficient attention in general and certainly not in injury prevention counseling for children younger than 4 years. Anticipatory guidance for pedestrian injury should be incorporated before 1 year of age. Effective strategies must be based on the epidemiology of childhood injury. Pediatricians and other pediatric health care providers are in a unique position to render injury prevention services to their patients. Integrating injury prevention messages in the context of developmental assessments of the child is 1 strategy. These data can also be used for complementary childhood injury prevention strategies such as early intervention programs for high-risk families for child abuse and neglect, media and advocacy campaigns, public policies, and environmental and product design.
