Chronic pain in children and young people

Mechanisms of pain in aging and age-related conditions: Focus on caregivers

Pain is a complex, subjective experience that can significantly impact quality of life, particularly in aging individuals, by adversely affecting physical and emotional well-being. Whereas acute pain usually serves a protective function, chronic pain is a persistent pathological condition that contributes to functional deficits, cognitive decline, and emotional disturbances in the elderly. Despite substantial progress that has been made in characterizing age-related changes in pain, complete mechanistic details of pain processing mechanisms in the aging patient remain unknown. Pain is particularly under-recognized and under-managed in the elderly, especially among patients with Alzheimer's disease (AD), Alzheimer's disease-related dementias (ADRD), and other age-related conditions. Furthermore, difficulties in assessing pain in patients with AD/ADRD and other age-related conditions may contribute to the familial caregiver burden. The purpose of this article is to discuss the mechanisms and risk factors for chronic pain development and persistence, with a particular focus on age-related changes. Our article also highlights the importance of caregivers working with aging chronic pain patients, and emphasizes the urgent need for increased legislative awareness and improved pain management in these populations to substantially alleviate caregiver burden.

The occurrence of internalizing problems and chronic pain symptoms in early childhood: what comes first?

Chronic pain and internalizing problems are characterized by concurrent associations but the directionality of this relationship in early childhood remains unclear. This prospective study aimed to investigate the bidirectional effect of chronic pain and internalizing problems and test the persistence of pain over time in a population-based sample of preschoolers. The study was embedded in Generation R, a large population-based cohort. Mothers of 3,996 children assessed their child's experienced pain and internalizing problems at 3 and 6 years. At 3 years, paternal reports were available too. Reports of family functioning, discipline practices and parental psychopathology were also collected. The prevalence of chronic pain was 2.7% (106) and 8.0% (294) at baseline and follow-up, respectively. The presence of internalizing problems at child age 3 years predicted chronic pain at 6 years, for both maternal (OR 1.05, 95% CI 1.02,1.07, p < 0.001) and paternal (OR 1.03, 95%CI 1.00, 1.06, p < 0.05) internalizing problem reports, when adjusted for potential confounding factors. In contrast, chronic pain did not increase the likelihood of internalizing problems. The temporal relationship between chronic pain and internalizing problems appears to follow a largely unidirectional trend in early childhood, with internalizing problems increasing the likelihood of concurrent physical symptoms. Current understanding of the directionality of this relationship, highlights the importance for comprehensive assessment of psychiatric problems contributing to the manifestation of chronic pain.

Sling suspension therapy is an effective treatment method of juvenile spinal osteochondrosis in adolescent girls

BACKGROUND

Juvenile spinal osteochondrosis (JSO) affects vertebral endplates and may cause intervertebral discs alterations. The condition is typically related to pain, and weakness and shortening of trunk muscles. Sling suspension therapy (SST) has been shown to reduce lumbar pain effectively. It is, however, unclear whether SST is superior to other treatment methods in reducing pain, correcting posture, and activating trunk stabilizers in JSO.

OBJECTIVE

In this study, we intended to compare the effectiveness of two different exercise modalities; Sling Suspension Therapy and Gym Ball Exercise in the treatment of JSO in adolescent girls.

METHODS

A randomised controlled single centre clinical trial was carried out in an inpatient rehabilitation unit at a sanatorium. Forty adolescent girls (age 16.3 ± 0.47 yrs.), who were diagnosed with JSO (according to ICD-10 Version: 2016 - M 42.0) were randomly assigned into two groups: Group 1 - Sling suspension therapy (SST), Group 2 - Gym ball exercises (GBE). Both groups received interventions for 3 weeks, 15 sessions, and 30 minutes a day for 5 consecutive days a week. Back pain, endurance of trunk muscles and standing posture were evaluated pre- and post-interventions.

RESULTS

Both groups demonstrated significant improvement in all measured outcomes. SST was more effective in reducing pain (p< 0.05), increasing the endurance of trunk muscles (p< 0.05) and improving the standing posture (p< 0.05) compared to GBE (p< 0.05).

CONCLUSIONS

Sling suspension therapy is more effective compared with Gym ball exercises in the treatment of juvenile spinal osteochondrosis in adolescent girls in terms of back pain, posture and endurance of trunk muscles.

Anterior Cutaneous Nerve Entrapment Syndrome in Children

PURPOSE

The purpose of this manuscript is to report on an entity known as Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) and its relevance to chronic abdominal pain encountered in children.

METHODS

Following institutional review board approval, we retrospectively reviewed patients who underwent operation for presumed ACNES from 2011-2014. Variables reviewed included age, gender, age at surgery, time from onset of pain to surgery, additional medical treatments, and surgery performed. The main outcome measure was amelioration of pain.

RESULTS

Nine patients met the study criteria whereby 7 were female and 2 were male patients. Median age at time of surgery was 14 years (range: 10-19 years) and time from onset of symptoms to surgery was 10 months (range: 0.5-60 months). Eight reported complete resolution of the original symptoms in follow-up appointments. One patient reported new, yet similar symptoms on her opposite trunk.

CONCLUSION

ACNES is a reported cause of chronic abdominal pain that can be managed surgically in the pediatric patient once medical management has been optimized. Close collaboration between surgeons and pain specialists helps identify patients who will benefit from surgical interventions and consideration of this condition could result in more timely pain relief in children. Further studies on a larger scale are needed to determine the long-term outcomes of this procedure.

Pain assessment in children undergoing venipuncture: the Wong-Baker faces scale versus skin conductance fluctuations

The aim of this study was to evaluate the efficacy of the subjective Wong–Baker faces pain rating scale (WBFS) and of the objective skin conductance fluctuation (SCF) test in assessing pain in children undergoing venipuncture. One-hundred and fifty children (aged 5–16 years) entered the study. All underwent venipuncture at the antecubital fossa to collect blood specimens for routine testing in the same environmental conditions. After venipuncture, the children indicated their pain intensity using the WBFS, whereas the number of SCFs was recorded before, during and after venipuncture. So, pain level was measured in each child with WBFS and SCF. We found that the level of WBFS-assessed pain was lower in all children, particularly those above 8 years of age, than SCF-assessed pain (p < 0.0001). Moreover, the number of SCFs was significantly higher during venipuncture than before or after venipuncture (p < 0.0001). At multivariate regression analysis, age and previous experience of venipuncture influenced the WBFS (β = −1.81, p < 0.001, and β = −0.86, p < 0.001, respectively) but not SCFs. In conclusion, although both procedures can be useful for research and clinical practice, our findings show that WBFS was affected by age and previous venipuncture, whereas SCF produced uniform data. If verified in other studies, our results should be taken into account when using these tools to evaluate pain in children.

Surgery for abdominal wall pain caused by cutaneous nerve entrapment in children-a single institution experience in the last 5 years

BACKGROUND

Chronic abdominal pain (CAP) is a serious medical condition which needs to be approached with great attention. Chronic abdominal pain may be caused by entrapment of cutaneous branches of intercostal nerves (ACNES).

OBJECTIVES

The aim of this study is the surgery for abdominal wall pain which caused by cutaneous nerve entrapment in children during last 5 years.

MATERIALS AND METHODS

In all children with ACNES, we tried conservative treatment with anesthetic and steroid injections. In children who were refractory to conservative treatment, we received surgical procedure like sectioning the entrapped nerve to obtain relief.

RESULTS

In 12 pediatric patients with chronic abdominal pain, we diagnosed ACNES. Each presented with abdominal pain and a positive Carnett sign. Local nerve blocks using anesthetic and steroid injections are the treatment. In all patients, we tried with local nerve block. In 3 patients, pain improvement occurs in the few minutes, and they were without pain after 5 days. In other 4 patients required a reinjection for pain recurrence. In one patients pain was gone. The maximum reinjection was 3. In other 5 patients, we did operative treatment like sectioning the entrapped nerve.

CONCLUSIONS

Some children with CAP have ACNES. In all children with ACNES, we recommended local nerve blocks. If the local block in 3 times is not helping, neurectomy of the peripheral nerve is method of choice.
