Increased nocturnal activity and impaired sleep maintenance in abused children.

OBJECTIVE: Previous studies have suggested that sleep disturbance may be the "hallmark of posttraumatic stress disorder," although several investigations have failed to find evidence for sleep disruption. The purpose of this study was to determine whether intense averse stimulation during early development, in the form of physical and/or sexual abuse, led to disruption of sleep and nocturnal activity. METHOD: Nineteen prepubertal children with documented abuse were compared with 15 nonabused normal controls and 10 depressed children. All subjects received a complete semistructured diagnostic interview. Ambulatory activity monitoring was used to evaluate sleep-related activity for three consecutive nights. Data were analyzed for nocturnal activity and algorithmic estimation of sleep initiation and continuity. RESULTS: Abused subjects were twice as active at night as normal and depressed children, and abused subjects emitted a greater percentage of their total daily activity during the night. Actigraph-derived sleep measures suggested that abused children had prolonged sleep latency and decreased sleep efficiency. Physically abused children had more impaired sleep efficiency than sexually abused children. CONCLUSION: Abused children have higher levels of nocturnal activity than normal controls or depressed children and appear to have more difficulty falling and staying asleep. Physical abuse appears to be the salient factor rather than posttraumatic stress disorder.

General trauma in a pediatric emergency department: spectrum and consultation patterns.

To assess the consultation patterns of pediatric emergency physicians in the management of injured children and to describe the spectrum of pediatric trauma, we retrospectively reviewed 601 patients treated in the emergency department for injuries during four one-week periods at a designated level I regional pediatric trauma center (50,000 patients/year) with a pediatric emergency medicine fellowship. The majority (94%) of pediatric trauma was minor; only 2% of children had injuries severe enough to require direct transfer to the operating room. The highest volume of patients, the greatest number of consultations, and the majority of admissions to the operating room occurred between 4 PM and midnight. No patients went to the operating room on the night shift. Musculoskeletal injuries constituted the predominant category of pediatric trauma, and lacerations were the most common specific injury. One half of all procedures involved laceration repair, and one third involved splinting or casting. Four hundred ten patients (68%) were managed by physicians in the emergency department without consultation. The orthopedic service performed one half of all consultations and admitted the largest number of patients; the majority of patients taken directly to the operating room had musculoskeletal injuries.(ABSTRACT TRUNCATED AT 250 WORDS)

The spectrum and frequency of illness presenting to a pediatric emergency department.

Knowledge of the spectrum and relative frequencies of pediatric emergencies is an important factor in developing appropriate training curricula for physicians treating children in emergency departments. To provide these data, we reviewed the records for four one-week periods (January, April, July, and October) of a large pediatric emergency department to describe the population in terms of age, chief complaints, diagnoses, time of arrival, seasonal variation, and disposition. There were 3796 log entries. Complete information on all variables was obtained on 3784 patients. Age ranged from one day to 39 years, and the mean age was 6.0 +/- 6.15 years. One half of all emergency department visits were by children three years old or younger. On the other hand, 12% of visits were by adolescents (ages 13 to 18), and one in 25 visits was made by an adult (greater than 18 years old). The majority of chief complaints and final diagnoses were related to infection and trauma. More than half of the patients arrived on the evening shift, between 4 pm and 12 am. Eleven percent of the children seen on day and evening shifts and 13% from the night shift were admitted. From the analysis of our data we recommend expanded skills in the management of minor trauma for pediatric residents, an emphasis on management of infections for nonpediatric emergency specialists, and extensive training in both pediatric and adult trauma for physicians in pediatric emergency medicine fellowships.
