Differential Diagnoses and Their Implications of Dandy-Walker Malformation or Isolated Cisterna Magna, a Case Study: Baby V

We explore the outcome of a fetus with a posterior fossa abnormality thought to be a Dandy-Walker malformation based on prenatal ultrasound imaging. The infant was later diagnosed by magnetic resonance imaging (MRI) as having an isolated cisterna magna. When assessing brain abnormalities, there is increased accuracy of prenatal MRI versus prenatal ultrasound. Accurate diagnosis of an infant is paramount so that an inheritance pattern, risk of recurrence, involvement of other systems, and a prognosis can be determined. Communicating with the family and supporting them with the correct information is then enhanced. It should be standard protocol to obtain a fetal MRI if an abnormal prenatal ultrasound of the brain is detected. Further research is needed to assess the accuracy of using MRI versus ultrasonography prenatally to diagnose posterior brain abnormalities.

The association between pediatric injury risks and parenting behaviours

BACKGROUND

Unintentional injuries are the leading cause of death in children ages 1-18 years. Many of these injuries to young children occur in their own homes. Although research has explored injury risk prevention strategies, historically, much of this research has focused on environmental changes and teaching safety practices. Currently, there appears to be a gap in current research exploring how parenting influences children's risk of injury.

METHODS

Mothers (n = 119) of children 5 years and younger were recruited from a paediatric clinic as a part of a larger study and completed measures of parenting challenges, developmentally sensitive parenting, child neglect, parental efficacy, and risk of potential injury situations. Hierarchical logistic regression was used to explore the extent to which developmentally insensitive parenting behaviours put parents at higher risk for behaviours that lead to unintentional injury in children and whether developmentally sensitive parenting behaviours protects children from injury. The association between demographic characteristics and injury risk behaviours was also examined.

RESULTS

Parents who reported more frequent insensitive parenting behaviours (i.e., yelling, spanking, and putting child in time out) were more likely to report putting their child in an incorrect car seat or taking their child out of a car seat while the car is still moving. In addition, younger parents were at greater risk of storing cleaners and medications unsafely.

CONCLUSION

Results from this study highlight the importance of supporting younger mothers and educating parents on effective parenting strategies when trying to prevent unintentional injury risks.

Developing tailored positive parenting messages for a clinic-based communication programme

BACKGROUND

Health care providers fill a central role in the prevention of both child abuse and neglect (CA/N) and unintentional childhood injury. Health communication interventions hold promise for promoting attitudes and behaviours among parents that increase positive parenting practices, which may be linked to decreased rates of intentional and unintentional childhood injuries. This manuscript describes the development of 'RISE Up', an ambulatory clinic-based childhood injury prevention programme that provides tailored, injury prevention print materials to parents of children ages 0-5.

METHODS

Fifteen semi-structured key informant interviews were conducted with clinic healthcare providers and staff to develop communication strategies and materials for caregivers. Cognitive response testing was then conducted with 20 caregivers of the priority population to assess all materials. Interviews were recorded, transcribed and analyzed using thematic coding methods.

RESULTS

Formative research revealed that health care providers and caregivers were very responsive to messages and materials. Health care providers reported that abuse and neglect were particularly relevant to their patients and noted several benefits to implementing the RISE Up programme in a health care setting. Caregivers generally found messages on reducing the risks of injuries, as well as the graphics displayed in the RISE Up programme to be helpful.

CONCLUSIONS

Addressing the common determinants of both intentional and unintentional childhood injury through customized print materials may be a useful component of comprehensive prevention efforts to address childhood injury risk with greater impact. Providers and parents responded favourably to this communication strategy.

Differential strength of association of child injury prevention attitudes and beliefs on practices: a case for audience segmentation

OBJECTIVE

Many injuries to children cannot be prevented without some degree of active behavior on the part of parents. A better understanding of social and cognitive determinants of parents' injury prevention behavior and the identification of potential subgroups for targeted message delivery could advance the effectiveness of educational and behavioral interventions. This study assessed the degree to which parents' injury prevention behavior is associated with theoretical determinants and examined whether this relation differs by age or birth order of child.

DESIGN

Cross sectional observational study.

SETTING

Three Midwestern pediatric clinics.

SUBJECTS

594 parents of children ages 0-4 attending routine well child visits.

MEASURES

Injury prevention attitudes, beliefs, and practices.

RESULTS

Overall, only modest relations were observed between injury beliefs and attitudes and injury prevention behaviors. However, these relations differed substantially by child age and birth order, with stronger associations observed for parents of older first born children. Outcome expectations and social norms were more strongly related to injury prevention behavior among parents of preschool children than among parents of infants and toddlers, while attitudes were more predictive for parents of first born children than parents of later born children.

CONCLUSIONS

These findings highlight the complexity of relations between theorized determinants and behavior, and suggest the potential utility of using audience segmentation strategies in behavioral interventions addressing injury prevention.

Efficacy of Topical Anesthetics to Reduce Pain in Premature Infants during Eye Examinations for Retinopathy of Prematurity

BACKGROUND:

Eye examinations for retinopathy of prematurity (ROP) are stressful and probably painful, but many ophthalmologists do not apply topical anesthetics because their efficacy in reducing pain has not been established.

OBJECTIVE:

To evaluate the potential benefits of topical anesthetic eye drops in reducing pain during neonatal eye examination for ROP.

METHODS:

Neonates born at ⩽30 weeks' gestation and expected to have at least 2 examinations for ROP were included. Patients were randomly assigned to receive either proparacaine HCl ophthalmic solution 0.5% or NaCl 0.9% (saline) eye drops prior to an eye examination. In a subsequent examination, each patient received the alternate treatment. Eye drops were prepared in the pharmacy in identical tuberculin syringes, and physicians, nurses, and pharmacists were blinded to the treatment given. Pain was measured using a scoring system with both physical and physiologic measures of pain (Premature Infant Pain Profile [PIPP], possible range 1–21), which has been validated in preterm infants. PIPP scoring was performed simultaneously by 2 nurses: 1 and 5 minutes before and after the eye examination and during initial placement of the eye speculum. The same ophthalmologist performed all examinations.

RESULTS:

Twenty-two patients were studied, with 11 infants receiving proparacaine and 11 receiving saline as the first treatment. Crossover was performed with a median of 17.5 days between treatments. Patients experienced significantly less pain at speculum insertion with proparacaine than with saline (paired difference −2.5 ± 3.4; p = 0.001).

CONCLUSIONS:

Topical anesthetic pretreatment reduces the pain response to eye examination for ROP and should become routine practice. Because this is not effective in all infants, additional measures to reduce pain should be taken.

Efficacy of sucrose to reduce pain in premature infants during eye examinations for retinopathy of prematurity

BACKGROUND

Eye examinations for retinopathy of prematurity (ROP) are painful to the neonate. The use of topical anesthetic for eye examinations to evaluate ROP is routine in our neonatal intensive care unit (NICU), but does not completely suppress painful responses. Sweet solutions have been shown to reduce procedural pain in newborns.

OBJECTIVE

To examine whether the addition of sucrose 24% to topical anesthetic improves procedural pain control during the ROP eye examination.

METHODS

Neonates born at < or = 30 weeks' gestation were included in this placebo-controlled, double-blind, crossover study. Patients were randomly assigned to receive treatment with either proparacaine HCl ophthalmic solution 0.5% plus 2 mL of sucrose 24% or proparacaine HCl ophthalmic solution 0.5% plus 2 mL of sterile water (placebo) prior to an eye examination. In a subsequent eye examination, each patient received the alternate treatment. Oral sucrose and sterile water were prepared in the pharmacy in identical syringes, and physicians, nurses, and pharmacists in the NICU were blinded to the treatment given. Pain was measured using the Premature Infant Pain Profile (PIPP) scoring system, which measures both physical and physiologic measures of pain, and the scores were simultaneously assessed by 2 study nurses. PIPP scores were recorded 1 and 5 minutes before and after the eye examination and during initial placement of the eye speculum. The same ophthalmologist performed all eye examinations. Several different definitions of a pain response were investigated.

RESULTS

Twenty-three infants were studied, with 12 receiving sucrose and 11 receiving placebo as the first treatment. For 3 of the 5 definitions of pain response, patients experienced significantly less pain at speculum insertion with sucrose than with placebo. After the ROP examination, pain responses were similar with either sucrose or placebo.

CONCLUSIONS

Oral sucrose may reduce the immediate pain response in premature infants undergoing eye examination for ROP.

Epidemiology of concussion in collegiate and high school football players

Despite evolutionary changes in protective equipment, head injury remains common in football. We investigated concussion in football and associated epidemiologic issues such as 1) incidence of injury, 2) common signs and symptoms, and 3) patterns in making return-to-play decisions. We received 242 of 392 surveys (62%) that were sent to high school and collegiate certified athletic trainers at the beginning of three football seasons. Of the 17,549 football players represented, 888 (5.1%) sustained at least one concussion, and 131 (14.7% of the 888) sustained a second injury during the same season. The greatest incidence of concussion was found at the high school (5.6%) and collegiate division III (5.5%) levels, suggesting that there is an association between level of play and the proportion of players injured. Players who sustained one concussion in a season were three times more likely to sustain a second concussion in the same season compared with uninjured players. Contact with artificial turf appears to be associated with a more serious concussion than contact with natural grass. Only 8.9% of all injuries involved loss of consciousness, while 86% involved a headache. Overall, 30.8% of all players sustaining a concussion returned to participation on the same day of injury.

Jockey injuries in the United States

CONTEXT

In the sport of horse racing, the position of the jockey and speed of the horse predispose the jockey to risk of injury.

OBJECTIVE

To estimate rates of medically treated injuries among professional jockeys and identify patterns of injury events.

DESIGN

Cross-sectional survey from data compiled by an insurance broker. Information on the cause of injury, location on the track, and body part injured was evaluated.

SETTING

Official races at US professional racing facilities (n = 114) from January 1, 1993, through December 31, 1996.

PARTICIPANTS

A licensed jockey population of approximately 2700 persons.

MAIN OUTCOME MEASURES

Annual injury incidence rates per 1000 jockey-years, as well as injury type, cause, and location on the track.

RESULTS

A total of 6545 injury events occurred during official races between 1993 and 1996 (606 per 1000 jockey-years). Nearly 1 in 5 injuries (18.8%) was to the jockey's head or neck. Other frequent sites included the leg (15.5%), foot/ankle (10.7%), back (10.7%), arm/hand (11.0%), and shoulder (9.6%). The most frequent location where injuries occurred was entering, within, or leaving the starting gate (35.1%), including 29.5% of head injuries, 39.8% of arm/hand injuries, and 52.0% of injuries to the leg/foot. Most head injuries resulted from being thrown from the horse (41.8%) or struck by the horse's head (23.2%). Being thrown from the horse was the cause of 55.1% of back and 49.6% of chest injuries.

CONCLUSIONS

Our data suggest that jockeys have a high injury rate. Efforts are needed to reduce the number of potential injury events on the track and to improve protective equipment so events do not lead to injury.

The North Carolina High School Athletic Injury Study: design and methodology

PURPOSE

Organized interscholastic athletics are an integral part of the educational program at almost every school level. With this growing popularity of sports and their inclusion in more public school programs, it becomes increasingly apparent that additional consideration must be given to the injury problem associated with sport. The North Carolina High School Athletic Injury Study (NCHSAIS) was undertaken to identify patterns of injury among male and female athletes in North Carolina high schools participating in any of 12 sports. Specific aims are to measure the incidence, severity and etiology of injuries; to determine the relationship of demographic factors and protective equipment, exposure to play, and school characteristics to injuries; to study the relationship of coaches' training and experience to injury occurrence; and to compare the incidence and severity of injury among female and male athletes in the same or comparable sports.

METHODS

A two-stage cluster sample of 100 high schools in North Carolina was selected for this 4-yr prospective study.

RESULTS

Participation by the initial sample or a random replacement was achieved for 91 of the 100 schools. Nonresponse occurred at multiple levels of the sample for this study, and the weekly participation form posed the greatest respondent burden.

CONCLUSIONS

The NCHSIAS offers a successful methodology for addressing sports injuries. In this paper we describe the design, methodology, and implementation issues that emerge in conducting a large scale epidemiological study in a population of high school athletes.
