RESUMO

INTRODUCTION/AIM: Young children's limited ability to self-report pain necessitates an understanding of the factors that influence pain ratings. The current paper examines the relative prediction of caregiver psychological factors and toddler pain behaviors on caregiver pain ratings post-vaccination. METHODS: One hundred fifty-six parent-toddler dyads were video recorded during pediatric vaccinations. Child pain behaviors were coded before, during, and after the needle using the Face, Legs, Activity, Cry, Consolability Scale and the Neonatal Facial Coding System). Caregivers rated their child's pain after the needle, reported pre- and post-needle worry during the visit, and completed rating scales assessing other areas of psychological functioning within 2 weeks after the appointment. Regression models were estimated to examine the relative contribution of child and caregiver factors to the prediction of caregiver pain ratings. RESULTS: The regression model predicting caregiver pain ratings from the toddlers' pain-related distress (facial activity immediately after the needle, overall pain-related behavior immediately after, 1-min and 2-min post-needle) and caregiver worry were significant (adjusted R-square = 0.21), with caregiver pre- and post-needle worry being the only significant predictors of caregiver pain ratings. CONCLUSIONS: This study outlines that although child distress behavior remains a significant influence on pain ratings during toddlerhood, when caregiver worry (pre- and post-needle) was entered into the model, they were the only significant predictors of caregiver pain ratings.

RESUMO

Introduction: Toddlers rely on their caregivers for regulatory support when faced with pain-related distress. The caregiver's ability to support their toddler relies on their capacity to regulate their own distress and respond effectively to the child's need for support. The aim of the current study was to describe patterns of caregiver-toddler physiological co-regulatory patterns, also known as attunement, during routine vaccinations across the second year of life. Methods: Caregiver-toddler dyads (N = 189) were part of a longitudinal cohort observed at either 12-, 18-, or 24-month well-baby vaccinations. Parallel-process growth-mixture modeling was used to examine patterns of dyadic physiological co-regulatory responses, indexed by high-frequency heart rate variability (HF-HRV). Results: Three groups of dyads were discerned. The largest group (approximately 80%) demonstrated physiological attunement, with a stable and parallel regulatory pattern of HF-HRV from baseline to postneedle. The second group (7.9%) had parallel regulatory trajectories but with notably lower (ie, less regulated) HF-HRV values, which indicates independent regulatory responses (ie, a lack of attunement among dyad members). The third group (11.1%) showed diverging regulatory trajectories: Caregivers showed a stable regulatory trajectory, but toddlers demonstrated a steep decrease followed by an increase in HF-HRV values that surpassed their baseline levels by the third minute postneedle. Post hoc analyses with the HF-HRV groupings explored heart rate patterns and potential predictors. Conclusions: These findings elucidate potential adaptive and maladaptive co-regulatory parasympathetic patterns in an acute pain context.

RESUMO

OBJECTIVE: The current study discusses the development and preliminary validation of an observational measure of caregivers' distress-promoting behavior (OUCHIE-RV) in the context of toddler routine vaccination. METHODS: Measure validation was based on a sample of caregiver-toddler dyads (N = 223) from a longitudinal cohort-sequential study who were observed during toddlers' 12-, 18-, or 24-month routine vaccinations. Validity was assessed using correlations and cross-lagged path analysis and associations were tested between OUCHIE-RV composite scores and toddlers' pain-related distress as well as caregivers' state anxiety, soothing behaviors, heart rate, and heart rate variability. Interrater reliability was examined using intraclass correlations (ICC) and kappa coefficients. RESULTS: Results of a cross-lagged path analysis indicated positive concurrent (ß = .27 to ß = .37) and cross-lagged predictive associations (ß = .01 to ß = .34) between OUCHIE-RV composite scores (reflecting the frequency and intensity of caregivers' distress-promoting behavior) and toddlers' pain-related distress. OUCHIE-RV composite scores were negatively associated with caregivers' concurrent use of physical comfort (r = -.34 to -.24) and rocking (r = -.36 to -.19) and showed minimal associations with caregivers' use of verbal reassurance (r = .06 to .12), state anxiety (r = -.02 to r = .09), heart rate (r = -.15 to r = .05), and heart rate variability (r = -.04 to r = .13). Interrater reliability was strong (Cohen's k = .86 to .97, ICC = .77 to .85). CONCLUSIONS: Findings provide support for the validity and reliability of the OUCHIE-RV as a research tool for measuring caregiver behaviors that promote toddlers' pain-related distress during routine vaccinations and contribute to a better understanding of the dynamics of caregiver-toddler interaction in acute pain contexts.

RESUMO

OBJECTIVE: Previous research discerned 3 groups of caregiver-toddler dyads that differed in their physiological coregulatory patterns, also known as physiological attunement, during routine vaccinations in the second year of life. One group of dyads (80% of sample) displayed an attuned regulatory pattern, and 2 groups of dyads (20% of sample) showed maladaptive attunement patterns (ie, a lack of attunement or misattunement). The objective of the current study was to examine how well the pain-related distress of children and caregivers during vaccination predicted these patterns. METHODS: Caregiver-toddler dyads (N = 189) were part of a longitudinal cohort observed at either 12-, 18-, or 24-month vaccination appointments. The caregiver's self-report of worry was assessed before and after the needle, and the child behavioral pain-related distress was also measured during the vaccination appointment. Logistic regression was used to determine how well these variables predicted caregiver-child physiological attunement patterns, as indexed by high-frequency heart rate variability. RESULTS: Higher behavioral pain-related distress at various timepoints after the needle were associated with membership in the dyad groups that showed misattunement or lack of attunement. Further, caregivers with higher preneedle worry and lower postneedle worry had a greater likelihood of belonging to groups that showed a maladaptive attunement pattern. DISCUSSION: Findings suggest that caregivers who experience distress associated with their toddlers' vaccination experience more difficulty coregulating with their child during vaccination, and these children are at risk of experiencing higher levels of pain-related distress. This research highlights the need to help caregivers support their children's regulation during vaccination.

RESUMO

ABSTRACT: The purpose of this study was to further our understanding of early childhood pain-related distress regulation. Concurrent and predictive relations between child-led emotion regulation (ER) behaviors and pain-related distress during vaccination were examined at 2 different ages using autoregressive cross-lagged path analyses. Toddlers were video-recorded at the 12- and 18-month routine vaccination appointments (12-month-old [N = 163]; 18-month-old [N = 149]). At 1, 2, and 3 minutes postneedle, videos were coded for 3 clusters of child-led ER behaviors (disengagement of attention, parent-focused behaviors, and physical self-soothing) and pain-related distress. The concurrent and predictive relations between child-led ER behaviors and pain-related distress behaviors were assessed using 6 models (3 emotion regulation behaviors by 2 ages). At 18 months, disengagement of attention was significantly negatively related to pain-related distress at 1 minute postneedle, and pain-related distress at 1 minute postneedle was significantly related to less disengagement of attention at 2 minutes postneedle. Parent-focused behaviors had significant positive relations with pain-related distress at both ages, with stronger magnitudes at 18 months. Physical self-soothing was significantly related to less pain-related distress at both ages. Taken together, these findings suggest that disengagement of attention and physical self-soothing may serve more of a regulatory function during toddlerhood, whereas parent-focused behaviors may serve more of a function of gaining parent support for regulation. This study is the first to assess these relations during routine vaccination in toddlerhood and suggests that toddlers in the second year of life are beginning to play a bigger role in their own regulation from painful procedures than earlier in infancy.

RESUMO

BACKGROUND AND OBJECTIVES: Viral respiratory infections are common in children, and practice guidelines do not recommend routine testing for typical viral illnesses. Despite results often not impacting care, nasopharyngeal swabs for viral testing are frequently performed and are an uncomfortable procedure. The aim of this initiative was to decrease unnecessary respiratory viral testing (RVT) in the emergency department (ED) and the pediatric medicine wards (PMWs) by 50% and 25%, respectively, over 36 months. METHODS: An expert panel reviewed published guidelines and appropriate evidence to formulate an RVT pathway using plan-do-study-act cycles. A multifaceted improvement strategy was developed that included implementing 2 newer, more effective tests when testing was deemed necessary; electronic order modifications with force functions; audit and feedback; and education. By using statistical process control charts, the outcomes analyzed were the percentage of RVT ordered in the ED and the rate of RVT ordered on the PMWs. Balancing measures included return visits leading to admission and inpatient viral nosocomial outbreaks. RESULTS: The RVT rate decreased from a mean of 3.0% to 0.5% of ED visits and from 44.3 to 30.1 per 1000 patient days on the PMWs and was sustained throughout the study. Even when accounting for the new rapid influenza test available in the ED, a 50% decrease in overall ED RVT was still achieved without any significant impact on return visits leading to admission or inpatient nosocomial infections. CONCLUSIONS: Through implementation of a standardized, electronically integrated RVT pathway, a decrease in unnecessary RVT was successfully achieved. Audit and feedback, reminders, and biannual education all supported long-term sustainability of this initiative.

RESUMO

There is considerable variability regarding the convergence between behavioral and biological aspects of distress responses in toddlerhood, and little research has investigated the convergence of these measures in high distress. The aim of the current study was to describe patterns of distress responses to vaccinations as indexed by both pain-related behavioral distress and heart rate (HR) at 12 and 18 months. Caregiver-toddler dyads were part of an ongoing longitudinal cohort observed during 12- (N = 158) and 18-month (N = 122) well-baby vaccinations. Parallel-process growth mixture models discerned two distinct groups at 12 months and three distinct groups at 18 months. All groups had comparable pain-related behavioral distress and HR responses post-vaccination, with most participants displaying high arousal and regulation to baseline levels following the vaccination. However, at 18 months, an important minority had a blunted response or did not regulate to a low level of distress by 3 min post-needle. Post hoc analyses revealed that higher baseline pain-related behavioral distress predicted membership in the majority groups at 12 and 18 months. These results highlight the developmental differences and variability in behavioral and cardiac indicators of distress regulation across the second year of life.

RESUMO

The aim of this study was to examine the concurrent and predictive relations between healthy toddlers' pain behavior and cardiac indicators (ie, heart rate [HR] and respiratory sinus arrhythmia [RSA]) during routine vaccinations. Caregiver-infant dyads were part of a longitudinal cohort observed during their 12- and 18-month vaccinations. Behavioral and cardiac data were simultaneously collected for 1-minute preneedle and 3-minutes postneedle. Videotapes were coded for pain behaviors (FLACC; Merkel et al., 1997), and cardiac data were analyzed (HR, RSA) during sequential 30-second epochs. Four separate cross-lagged path models were estimated using data from the 12- (n = 147) and 18-month (n = 122) vaccinations. Across 12- and 18-month vaccinations, predictive within-measure relations were consistent for FLACC, HR, and RSA, reflecting good stability of these pain indicators. Behavioral indicators predicted subsequent HR and RSA within the immediate postneedle period. Both baseline behavior and HR/RSA predicted future pain scores. Concurrent residual relations between behavioral and cardiac indicators were inconsistent across time and indicators. Results suggest that behavioral and cardiac indicators reflect unique aspects of the nociceptive response. As such, multimodal assessment tools should be used and contextualized by child age, cardiac indicator, baseline behavior/physiology, and pain phase.

RESUMO

Diencephalic syndrome is a rare clinical entity, traditionally encompassing severe failure to thrive, nystagmus, and hyperkinesis, secondary to an intracranial neoplasm that is classically located in the hypothalamic region and its vicinity. However, the presenting features can be variable, often resulting in delayed diagnosis, which may worsen prognosis. This case report describes the atypical presentation of a posterior fossa tumor with features reminiscent of diencephalic syndrome that have not previously been reported in the literature. We report a 21-month-old girl with a cervicomedullary brainstem astrocytoma, who presented with isolated gross motor developmental delay, decreased growth velocity, and stridor. The neurologic signs frequently reported in patients with diencephalic syndrome were absent; however, severe failure to thrive was present. This case broadens the etiologic differential diagnosis of diencephalic syndrome in addition to the traditional hypothalamic region tumor location. This case urges physicians to consider central neurologic processes in the differential diagnosis of children with refractory failure to thrive with or without classical features of diencephalic syndrome, in whom etiology is not identified by routine investigations, given its importance in determining prognosis and management.

RESUMO

INTRODUCTION: Bacterial sepsis is more common and potentially life threatening in children with sickle cell disease (SCD). Identification of variables that predict bacteremia may aid clinicians in recognizing patients with SCD at higher risk for sepsis. OBJECTIVE: To determine whether absolute neutrophil count (ANC) >20×10/L is an independent risk factor for bacteremia in children with SCD and to identify other predictors of bacteremia in this population. METHODS: A case-control study was conducted. Subjects were 0 to 18 years of age admitted to a tertiary care pediatric hospital over a 17-year period with SCD and fever at presentation. Cases had bacteremia, whereas controls had negative blood cultures. RESULTS: Data were analyzed for 40 cases and 120 controls. ANC>20×10/L was significantly more prevalent among cases (odds ratio [OR], 7.0; 95% confidence interval [CI], 2.6-18.9). Cases were more likely to have emesis (OR, 2.9; 95% CI, 1.0-8.4) and a higher proportion of band cells (OR, 1.3; 95% CI, 1.1-1.4) at presentation. CONCLUSIONS: In a febrile child with SCD, an ANC>20×10/L, a higher proportion of band cells, and the presence of vomiting were associated with an increased likelihood of bacteremia.
