ABSTRACT

Numerous behavioral pain measures have been validated for young children, but none is appropriate to assess pain in emergency departments (EDs), where caregivers need a simple, easily completed scale. Our objective was to elaborate and validate a tool, relevant in any painful situation, with agitation or prostration, and for any age under 7 years. Five items (scored 0 to 3) were developed by pediatric pain and emergency caregivers. The new scale, called EVENDOL, was tested at children's arrival and after analgesics, at rest, and during mobilization. The validation study included 291 children from birth to 7 years old in 4 French EDs, and independent observations by the ED nurse and a researcher. The Cronbach coefficient was excellent (0.83 to 0.92). Construct validity was demonstrated by a decrease in scores after nalbuphine: 8.14 to 3.62 of 15 at rest (P<.0001), 11.87 to 6.65 at mobilization (P = .0011); by good correlations between EVENDOL and nurse or researcher numerical scores: 0.79 to 0.92 (P<.0001); by good correlations between children's self-assessment scores and EVENDOL in children ages 4 to 7 (0.64 to 0.93). Discriminant validity with tiredness, anxiety, and hunger was good. Interrater reliability was excellent between nurses and researcher (weighted kappa 0.7 to 0.9), and in a group of 6 nurses (simultaneous assessment of 122 videos). The treatment threshold was determined at 4 of 15. EVENDOL has excellent validity and can be used for all children under age 7 in EDs, for any age and any pain, acute as well as more prolonged.

ABSTRACT

Microtubule disruption provokes cytoskeleton and cell adhesion changes whose importance for apoptosis induction remains unclear. The present study focuses on the functional and the molecular adhesion kinetics that are induced by microtubule disruption-mediated apoptosis. We showed that antimicrotubules induce a biphasic sequence of adhesion response that precedes the onset of apoptosis and focal adhesion kinase hydrolysis. Antimicrotubules first induced an increase of the cellular adhesion paralleled by the raise of focal adhesion sites and actin contractility, which was followed by a sharp decrease of cell adhesion and disorganization of focal adhesion and actin stress fibers. The latter sequence of events ends by cell rounding, detachment from the extracellular matrix, and cell death. Microtubule-disrupting agents induced a sustained paxillin phosphorylation, before the activation of apoptosis, that requires the prior activation of extracellular signal-regulated kinase and p38 but not c-Jun NH(2)-terminal kinase. Interestingly, integrin-linked kinase overexpression rescued the antimicrotubule-mediated loss of cell viability. Altogether, these results propound that antimicrotubule agents induce anoikis through the loss of focal adhesion structure integrity.

ABSTRACT

CONTEXT: The Standards, Options and Recommendations (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the 20 French cancer centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To establish the Standards, Options and Recommendations clinical practice guidelines for the management of procedure related pain (lumbar puncture, bone marrow aspiration or biopsy, blood sampling) in children oncology patients. To define, on the basis of the critical appraisal of the best available evidence and expert agreement, the clinical situations in which a pain preventive strategy should be implemented. METHODS: MEDLINE was searched using specific search strategies from January 1966 to August 2004. Literature monitoring was performed to identify controlled clinical trials published in 2005. RESULTS: A total of 57 references were identified. Clinical guidelines have been defined for each invasive procedure.

ABSTRACT

BACKGROUND: Recurrent complex regional pain syndrome I is not rare in the pediatric population. The authors conducted this study to evaluate the efficacy of continuous peripheral nerve blocks with elastomeric disposable pumps associated with initial Bier blocks for the treatment of recurrent complex regional pain syndrome I in children. METHODS: After parental informed consent, 13 children who did not respond to conventional complex regional pain syndrome treatment were included (mean age, 13 yr; range, 9-16 yr). After general anesthesia, peripheral nerve block was performed using 0.5 ml/kg lidocaine, 1%, with epinephrine and 0.5% ropivacaine injected in the peripheral nerve block catheter. Then, a 20-min Bier block was performed using a tourniquet and 0.2 ml/kg lidocaine, 1%; 3 ml/kg hydroxyethyl starch 130/06; and 5 mg/kg buflomedil injected intravenously. A solution of 0.1 ml . kg . h continuous ropivacaine, 0.2%, was infused through the catheter using an elastomeric pump for 96 h. Need for rescue analgesia, occurrence of side effects, and status of motor and sensory block were recorded at hours 1, 6, 12, 24, 48, 72, and 96. Children and parents completed a satisfaction assessment. All of the children had follow-up visits after 2 months. RESULTS: Postoperative analgesia was excellent. The median pain score was 0 for each period studied. Motor blockade was minimal before 12 h (median, 1) and absent thereafter. One child needed rescue analgesia. All children were able to walk easily after the initial 24-h period (walking score, > 4). Children and parents were all satisfied. Children returned home under parental surveillance beginning in the 24th hour. Neither peripheral nerve block nor Bier block caused side effects. After 2 months, none of the children exhibited any clinical symptom of recurrent complex regional pain syndrome. CONCLUSION: Ambulatory continuous peripheral nerve block associated with an initial Bier block seems to be a significant and novel contribution to treat recurrent pediatric complex regional pain syndrome I. It allows complete pain relief, early mobilization, and rapid return home, representing a psychological advantage for these children.

ABSTRACT

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, which started in 1993, is a collaboration between the French Federation of Cancer Centers (FNCLCC), the 20 French Regional Cancer Centers, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVE: To update clinical practice guidelines for the assessment of pain in adult or children with cancer in collaboration with the French society for pain study and treatment. METHOD: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guideline has been defined, the document is submitted for review by independent reviewers. RESULTS: This article is a summary version of the full document presenting the clinical practice guidelines with algorithms. The main recommendations concern the means used to evaluate pain and its consequences and their use in specific cases (acute or chronic pain, patients able to communicate or not, children under or over 6 years old). Others recommendations were also established concerning the evaluation ofpsychological, social and family context, the evaluation of pain in hospital or at home, in terminal phase patients and for the establishment of a therapeutic strategy and follow-up of patient with pain.

ABSTRACT

Continuous peripheral nerve blocks (CPNB) after pediatric major orthopedic surgery are not widely used. We conducted a prospective descriptive study to evaluate the effectiveness of disposable elastomeric pumps for CPNB in children. After inducing general anesthesia, 25 consecutive children scheduled for major orthopedic surgery received a 0.5-mL/kg bolus of a mixture of 1% lidocaine with epinephrine and 0.25% bupivacaine in axillary, femoral, or popliteal catheters. After surgery, disposable pumps with 0.2% ropivacaine were connected. Pump flows were adjusted to the patient's weight. Postoperative pain was evaluated using a visual analog scale or Children and Infants Postoperative Pain Scale scores at H1, H6, H12, H24, and H48, as well as amounts of rescue analgesia, adverse events, and motor and sensory block. An ambulation score for the children was also evaluated. Eleven popliteal, nine femoral, and five axillary continuous blocks were performed. All the blocks were effective for surgery. The mean total dose consumption of 0.2% ropivacaine was 10.1 mg/kg. Disposable pump flow varied from -9.61% to +8.6% compared with the theoretical one. Postoperative analgesia was excellent. The median of pain score was zero at each period studied. Sensory and motor block were noted at H1 and decreased from the sixth hour. No adverse events were noted. We concluded that the use of elastomeric disposable pumps for CPNB in children was an effective technique.
