Need for pharmacological analgesia after cast immobilisation in children with bone fractures: an observational cross-sectional study

BackgroundBone fractures are a common reason for children and adolescents to seek evaluation in the ED. Little is known about the pain experienced after cast immobilisation and discharge from the ED and its optimal management. We aimed to investigate the administration of pharmacological analgesia in the first days after cast immobilisation and to identify possible influencing variables.MethodsA prospective observational cross-sectional study was conducted at the ED of the children’s hospital, Institute for Maternal and Child Health of Trieste, Italy, from October 2019 to June 2020. Patients aged 0–17 years with bone fractures were included. The primary outcome was the administration of analgesia during the 10 days following discharge, while secondary outcomes were the associated variables, including age, gender, fracture type and location, the mean limitation in usual activities and the frequency of re-evaluation at the ED for pain. Data were recorded through a questionnaire, completed by caregivers and collected by the researchers mainly through a telephone interview. The primary endpoint was evaluated as the ratio between the number of children who took at least one analgesic dose and the total enrolled children, while Χ2 or Fisher’s exact tests were used to assess secondary outcomes.ResultsDuring the study period, 213 patients, mean age 10 years (IQR: 8–13), were enrolled. Among them, 137 (64.3%) did not take any analgesic during follow-up. Among children who were administered analgesia, 22 (28.9%) received it only on the first day, and 47 (61.8%) for less than 5 days. One hundred and sixty one patients (75.6%) did not report any limitation in usual activities because of pain. The administration of analgesia was not related to the child’s age, gender or fracture site. Displaced fractures were associated with significantly more frequent analgesia being taken (OR 5.5, 95% CI 1.4 to 21.0).ConclusionAlthough some studies recommend scheduled analgesic treatment after discharge for bone fractures, this study would suggest analgesia on demand in children with non-displaced fractures, limiting scheduled analgesia to children with displaced fractures.

Post-Mastectomy Pain: An Updated Overview on Risk Factors, Predictors, and Markers

After breast surgery, women frequently develop chronic post-mastectomy pain (PMP). PMP refers to the occurrence of pain in and around the area of the mastectomy lasting beyond three months after surgery. The nature of factors leading to PMP is not well known. When PMP is refractory to analgesic treatment, it negatively impacts the lives of patients, increasing emotional stress and disability. For this reason, optimizing the quality of life of patients treated for this pathology has gained more importance. On the basis of the findings and opinions above, we present an overview of risk factors and predictors to be used as potential biomarkers in the personalized management of individual PMP. For this overview, we discuss scientific articles published in peer-reviewed journals written in the English language describing risk factors, predictors, and potential biomarkers associated with chronic pain after breast surgery. Our overview confirms that the identification of women at risk for PMP is fundamental to setting up the best treatment to prevent this outcome. Clinical practice can be planned through the interpretation of genotyping data, choosing drugs, and tailoring doses for each patient with the aim to provide safer and more effective individual analgesic treatment.

Racial and Ethnic Disparities in Pain Management of Children With Limb Fractures or Suspected Appendicitis: A Retrospective Cross-Sectional Study

Objective: To evaluate whether racial/ethnical differences in analgesia administration existed in two different cohorts of children with painful conditions: children with either limb fracture or suspected appendicitis.Methods: Retrospective cross-sectional analysis of children visiting a pediatric emergency department (Boston Children Hospital) for limb fracture or suspected appendicitis from 2011 to 2015. We computed the proportion of children that received any analgesic treatment and any opioid analgesia. We performed multivariable logistic regressions to investigate race/ethnicity differences in analgesic and opioid administration, after adjusting for pain score, demographics and visit covariates.Results: Among the 8,347 children with a limb fracture and the 4,780 with suspected appendicitis, 65.0 and 60.9% received any analgesic treatment, and 35.9 and 33.4% an opioid analgesia, respectively. Compared to White non-Hispanic Children, Black non-Hispanic children and Hispanic children were less likely to receive opioid analgesia in both the limb fracture cohort [Black: aOR = 0.61 (95% CI, 0.50–0.75); Hispanic aOR = 0.66 (95% CI, 0.55–0.80)] and in the suspected appendicitis cohort [Black: aOR = 0.75 (95% CI, 0.58–0.96); Hispanic aOR = 0.78 (95% CI, 0.63–0.96)]. In the limb fracture cohort, Black non-Hispanic children and Hispanic children were more likely to receive any analgesic treatment (non-opioid or opioid) than White non-Hispanic children [Black: aOR = 1.63 (95% CI, 1.33–2.01); Hispanic aOR = 1.43 (95% CI, 1.19–1.72)].Conclusion: Racial and ethnic disparities exist in the pain management of two different painful conditions, which suggests true inequities in health care delivery. To provide equitable analgesic care, emergency departments should monitor variation in analgesic management and develop appropriate universal interventions.

Standard procedure for the pharmacotherapy of pain in childhood

Physicians of all specialties encounter patients in pain. The basis of the philosophy of caring children is not to question the existence of pain but to predict, prevent, and adequately treat it. Acute pain services implement preventive and multimodal analgesic treatment to increase the analgesic effect at the lowest possible doses to minimize undesirable effects of individual drugs. However, this service cannot be provided in all hospitals 24 hours a day. This study provides a clear, color-coded recommendation for pain relief in children, which provides a quick, rational, and safe choice of analgesics or their safe and effective combinations and dosage for each age group.

Analgesic Effect of a 5% Lidocaine Patch in Patients With Opioid Treatment-Resistant Neuropathic Cancer Pain

PurposeLimited efficacy has been observed when using morphine to treat neuropathic pain. Lidocaine patches reduce neuropathic pain in post-herpetic neuralgia, but their benefits for cancer-related neuropathic pain remain unclear. This study aimed to demonstrate a useful treatment for cancer-related neuropathic pain. The primary endpoint was pain intensity evaluated by the visual analog scale (VAS). The secondary endpoints were the pain relief score and the quality of analgesic treatment. MethodsWe assessed the efficacy and safety of lidocaine patches in patients experiencing neuropathic cancer pain. Terminal cancer patients with opioid treatment resistance participated in the 3-day study. ResultsThe results showed a statistically significant difference in the median VAS over three days (Kruskal-Wallis test, P<0.0001). The median VAS pain intensity from Day 1 to Day 3 was 4.0 with 95% C.I. (3.3, 5.0), 3.0 (2.5, 3.5) and 2.5 (2.0, 3.0), respectively. The difference between the median VAS pain intensities of any two days was statistically significant (Wilcoxon signed-rank test, P < 0.0001). There was no statistically significant difference in the pain relief score or the quality of analgesic treatment. ConclusionIn this study, the 5% lidocaine transdermal patch reduced the VAS pain intensity in neuropathic cancer patients with morphine resistance. The transdermal patch is generally useful and well-tolerated.

Retrospective Evaluation of Claw Lesions, Inflammatory Markers, and Outcome After Abomasal Rolling in Cattle with Left Displacement of the Abomasum

Lameness is often diagnosed in cattle with left displacement of the abomasum (LDA). Laterality of lying has an effect on the etiology of LDA, and lame cows prefer to lie on the affected limb. The objective of this study was to investigate the possible association between laterality of claw lesion and presence of LDA. The medical records of 252 cattle presented with a diagnosis of LDA and subjected to a diagnostic examination of claw lesions over a period of 11 years (2009–2019), were analyzed retrospectively. Data were evaluated for presence and localization of claw lesion, concentrations of inflammatory markers, and abomasal rolling as therapy. At least one claw lesion was diagnosed in 46.4% of cattle. There was no association between laterality of claw lesion and LDA. Presence of claw lesion or oral drench and/or analgesic treatment did not have an effect on occurrence of relapse. A high number of cattle was diagnosed with both LDA and claw lesions. Focus should lie on preventing painful claw lesions in the dry and the early post-partum period. The high recurrence rate after abomasal rolling suggests that abomasal rolling should only be considered as a therapy for temporary relief, and surgical procedures should be discussed with farmers.
