Peer Victimization, Posttraumatic Stress Symptoms, and Chronic Pain: A Longitudinal Examination

Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10 to 18 years recruited from a tertiary-level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. The pain was reassessed at a 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in the analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.

Pain and Post-traumatic Stress Disorder Symptoms: Dyadic Relationships Between Canadian Armed Forces Members/Veterans With Chronic Pain and Their Offspring

Chronic pain and mental health issues occur at higher rates in Veterans than the general population. One widely recognized mental health issue faced by Veterans is post-traumatic stress disorder (PTSD). Trauma symptoms and pain frequently co-occur and are mutually maintained due to shared mechanisms. Many Veterans are also parents. Parental physical and mental health issues significantly predict children's chronic pain and related functioning, which can continue into adulthood. Only 1 U.S.-based study has examined pain in the offspring of Veterans, suggesting a heightened risk for pain. Research to date has not examined the associations between trauma and pain and the dyadic influences of these symptoms, among Veterans, and their children. The current study aimed to describe pain characteristics in Canadian Armed Forces Members/Veterans with chronic pain and their offspring (youth and adult children aged 9-38). Cross-lagged panel models were conducted to examine dyadic relationships between pain interference and trauma symptoms of Canadian Armed Forces Members/Veterans and their offspring. Over half of adult offspring and over one-quarter of youth offspring reported chronic pain. Results revealed effects between one's own symptoms of PTSD and pain interference. No significant effects of parents on offspring or offspring on parents were found. The findings highlight the interconnection between pain and PTSD consistent with mutual maintenance models and a lack of significant interpersonal findings suggestive of resiliency in this unique population. PERSPECTIVE: We characterized chronic pain in the offspring of Canadian Armed Forces Members/Veterans with chronic pain and examined dyadic relationships between PTSD symptoms and chronic pain interference. Findings revealed that PTSD symptoms and pain interference were related within Veterans and offspring, but no dyadic relationships were found, which could reflect resiliency.

Sleep disturbances, altered brain microstructure and chronic headache in youth

Chronic headache (persistent or recurrent headache for 3-months or longer) is highly prevalent among youth. While sleep disturbances have been associated with headache, their inter-relationship with brain connectivity remains unknown. This observational study examined whether self-report and actigraphy measures of sleep were associated with alterations to white matter tracts (i.e., uncinate fasciculus and cingulum) in youth with chronic headache versus healthy controls. Thirty youth aged 10-18 years with chronic headache and thirty controls underwent an MRI. Diffusion tensor images were obtained and mean fractional anisotropy values of the cingulum and uncinate were extracted. One-week prior to their MRI, youth wore an actigraph to obtain sleep duration, wake after sleep onset and sleep efficiency measures. Moreover, they completed questionnaires regarding their sleep quality and pain symptomatology. Linear regression was applied to examine the relationships between sleep (self-report and actigraphy), fractional anisotropy, and number of headache days per month. Self-report and actigraphy measures of sleep did not differ between patients and controls. However, poorer self-reported sleep quality was associated with lower fractional anisotropy values in the left uncinate (P = 0.05). Lower left uncinate fractional anisotropy was related to increased headache frequency (P = 0.002) in youth with chronic headache. Therefore, alterations to connectivity may be associated with the relationship between altered perceptions of sleep and headache chronicity.

Reframe the Pain: A Randomized Controlled Trial of a Parent-Led Memory-Reframing Intervention

Negatively-biased pain memories (ie, recalling more pain as compared to earlier reports) are a robust predictor of future pain experiences. This randomized controlled trial examined the efficacy of a memory-reframing intervention to reframe children's pain memories. Sixty-five children (54% girls, M_age=5.35 years) underwent a tonsillectomy and reported their levels of post-surgical pain intensity and pain-related fear. 2 weeks post-surgery, children and 1 of their parents were randomized to the memory-reframing intervention or control group. Following control/intervention instructions, parents and children reminisced about the past surgery as they normally would (control) or using the memory-reframing strategies (intervention). Children recalled their post-surgical pain intensity and pain-related fear one week later. Parents reported the intervention's acceptability. Recruitment statistics were used to assess feasibility. Controlling for initial pain intensity ratings and using the Faces Pain Scale Revised, children in the intervention group reported more accurate/positively-biased memories for day 1 post-surgery pain intensity (M = 2.60/10; 95% CI, 1.62 to 3.68), compared to children in the control group (M = 4.11/10; 95% CI, 3.12 to 5.03), η_p² = .07, p = .040. The intervention was acceptable and feasible. Optimal parent-child reminiscing about a past pain experience resulted in children remembering their pain more accurately/positively. Clinicaltrials.gov:NCT03538730. PERSPECTIVE: This article presents results of the first randomized controlled trial examining the efficacy of parent-led memory-reframing intervention to change children's memories for pain. Children of parents who were taught and engaged in optimal reminiscing about a past surgery experience remembered their pain intensity more accurately/positively.

The Socialization of Young Children's Empathy for Pain: The Role of Mother- and Father-Child Reminiscing

OBJECTIVE

Empathy for pain allows one to recognize, understand, and respond to another person's pain in a prosocial manner. Young children develop empathy for pain later than empathy for other negative emotions (e.g., sadness), which may be due to social learning. How parents reminisce with children about past painful events has been linked to children's pain cognitions (e.g., memory) and broader socioemotional development. The present study examined how parent-child reminiscing about pain may be linked to children's empathic behaviors toward another person's pain.

METHODS

One hundred and fourteen 4-year-old children (55% girls) and for each, one parent (51% fathers) completed a structured narrative elicitation task wherein they reminisced about a past painful autobiographical event for the child. Children were then observed responding in a lab-based empathy task wherein they witnessed a confederate pretending to hurt themselves. Children's empathic behaviors and parent-child narratives about past painful events were coded using established coding schemes.

RESULTS

Findings revealed that parents who used more neutral emotion language (e.g., How did you feel?) when discussing past painful events had children who exhibited more empathic concern in response to another's pain. Similarly, children who used more explanations when reminiscing about past painful events displayed more empathic concern about another's pain.

CONCLUSIONS

Findings highlight a key role of parent-child reminiscing about the past pain in the behavioral expression of empathy for pain in young children.

Hereditary haemorragic teleangectasia and pregnancy: case report

We report an uncommon case of a 38-years-old pregnant woman affected by HHT (Hereditary haemorrhagic telangiectasia; Osler-Weber-Rendu syndrome) who underwent to a caesarean section (CS) without any complication. The patient at 36th weeks+1 day pregnancy referred to the Emergency Obstetric Unit due to a intercostals pain on left side. On third day after admission the woman started travailing and physicians decided to perform the CS. Considering that no AVMs was found at MRI, a continuous spinal anaesthesia was planned. On postpartum day 4 the patient was discharged. This represents the only case published in the literature. Women with HHT, especially those with arteriovenous malformations (AVM), are at high risk in pregnancy due to physiological haemodynamic changes pregnancy associated. Early screening of patients with HHT for the presence of spinal cord or cerebral AVMs is recommended to optimise perioperative anaesthetic management and to avoid severe complications.

Intracranial hypotension and PRES: case report

We report a case of a woman presenting, 7 days after epidural analgesia for a caesarean section, to the emergency room for a worsening of the headache and tonico-clonic seizures. MRI showed alterations suggestive of the presence of intracranial hypotension (IH) as well as evidence of posterior reversible encephalopathy syndrome (PRES). She was treated with a blood patch which leads to the prompt regression of the clinical symptoms and follow-up MRI, after 15 days, showed complete resolution of radiological alterations. The possible pathogenetic relationship between IH, secondary to the inadvertent dural puncture, and PRES is discussed. We suggest that venous stagnation and hydrostatic edema, secondary to intracranial hypotension, probably played a crucial role in the pathogenesis of PRES.
