Abstract
Standardizing opioid management is challenging due to the absence of a ceiling dose, the unknown ideal therapeutic plasma level, and the lack of an clear relationship between dose and therapeutic response. Opioid rotation or conversion, which is switching from one opioid, route of administration, or both, to another, to improve therapeutic response and reduce toxicities, occurs in 20-40 percent of patients treated with opioids. Opioid conversion is often needed when there are adverse effects, toxicities, or inability to tolerate a certain opioid formulation. A majority of patients benefit from opioid conversion, leading to improved analgesia and less adverse effects. There are different published ways of converting opioids in the literature. This review of 20 years of literature is centered on opioid conversions and aims to discuss the complexity of converting opioids. We discuss study designs, outcomes and measures, pain phenotypes, patient characteristics, comparisons of equivalent doses between opioids, reconciling conversion ratios between opioids, routes, directional differences, half-lives and metabolites, interindividual variability, and comparison to package insert information. Palliative care specialists have not yet come to a consensus on the ideal opioid equianalgesic table; however, we discuss a recently updated table, based on retrospective evidence, that may serve as a gold standard for practical use in the palliative care population. More robust, well-designed studies are needed to validate and guide future opioid conversion data.

Abstract
Despite the enthusiasm surrounding novel targeted agents and immunotherapies, chemotherapy remains the mainstay treatment for most human malignancies, either alone or in combination. Yet, the burden of chemotherapy-associated adverse events (CAAEs) remains high and, importantly, is associated with considerable morbidity, mortality and costs that affect patients across multiple dimensions, including physical, emotional and social functioning. CAAEs can directly affect patient outcomes and indirectly increase the risk of cancer recurrence by compromising treatment intensity and continuity. Systematic efforts to identify and critically summarize the evidence on management approaches for CAAEs remain limited. Herein, we review the most common acute CAAEs having a major effect on survival, quality of life, function and/or continuation of optimal therapy. We focus on selected acute toxicities that occur during treatment, summarizing their underlying pathophysiology, multifactorial aetiologies, evidenced-based treatments, prevention strategies and management recommendations. We also summarize the available evidence on risk factors, validated risk assessment tools and other efforts to optimize symptom control in patients most likely to benefit in order to personalize the prevention and treatment of acute CAAEs. Finally, we discuss innovative symptom monitoring and supportive care interventions that are under development to further improve the outcomes of patients with cancer.

New insight into the analgesic recipe: A cohort study based on smart patient-controlled analgesia pumps records. Front Pharmacol 2022; 13:988070. [PMID: 36299897 PMCID: PMC9589502 DOI: 10.3389/fphar.2022.988070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 08/15/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose: Intravenous patient-controlled analgesia (IV-PCA) has been widely used; however, regimen criteria have not yet been established. In China, the most often used opioid is sufentanil, for which repeated doses are a concern, and empirical flurbiprofen axetil (FBP) as an adjuvant. We hypothesized that hydromorphone would be a better choice and also evaluated the effectiveness of FBP as an adjuvant. Methods: This historical cohort study was conducted in two tertiary hospitals in China and included 12,674 patients using hydromorphone or sufentanil for IV-PCA between April 1, 2017, and January 30, 2021. The primary outcome was analgesic insufficiency at static (AIS). The secondary outcomes included analgesic insufficiency with movement (AIM) and common opioid-related adverse effects such as postoperative nausea and vomiting (PONV) and dizziness. Results: Sufentanil, but not the sufentanil-FBP combination, was associated with higher risks of AIS and AIM compared to those for hydromorphone (OR 1.64 [1.23, 2.19], p < 0.001 and OR 1.42 [1.16, 1.73], p < 0.001). Hydromorphone combined with FBP also decreased the risk of both AIS and AIM compared to those for pure hydromorphone (OR 0.74 [0.61, 0.90], p = 0.003 and OR 0.80 [0.71, 0.91], p < 0.001). However, the risk of PONV was higher in patients aged ≤35 years using FBP (hydromorphone-FBP vs. hydromorphone and sufentanil-FBP vs. hydromorphone, OR 1.69 [1.22, 2.33], p = 0.001 and 1.79 [1.12, 2.86], p = 0.015). Conclusion: Hydromorphone was superior to sufentanil for IV-PCA in postoperative analgesia. Adding FBP may improve the analgesic effects of both hydromorphone and sufentanil but was associated with an increased risk of PONV in patients <35 years of age.

Ice-cream used as cryotherapy during high-dose melphalan conditioning reduces oral mucositis after autologous hematopoietic stem cell transplantation. Sci Rep 2021; 11:22507. [PMID: 34795377 PMCID: PMC8602377 DOI: 10.1038/s41598-021-02002-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 11/08/2021] [Indexed: 11/23/2022] Open
Abstract
Oral mucositis (OM) is one of the most frequent adverse events of high-dose conditioning chemotherapy with melphalan prior to autologous hematopoietic stem cell transplantation (AHSCT). It significantly reduces the patients’ quality of life. One of the preventive strategies for OM is cryotherapy. We retrospectively analyzed whether commercially available ice-cream could prevent OM during the melphalan infusion. We retrospectively analyzed 74 patients after AHSCT to see whether there is any correlation between OM and cryotherapy (ice-cream), melphalan dose (140 mg/m2 or 200 mg/m2). The incidence of OM in our study inversely correlated with cryotherapy in the form of ice-cream. Out of 74 patients receiving conditioning chemotherapy with high-dose melphalan, 52 received cryotherapy. Fifteen patients in the cryotherapy group (28.84%) developed OM, whereas 13 patients (59.09%) developed it in the group without cryotherapy. In a multiple linear regression test cryotherapy remained a significant protective factor against OM (p = 0.02) We have also seen the relationship between melphalan dose with OM (p < 0.005). Cryotherapy in the form of ice-cream is associated with a lower rate of OM and, therefore, could potentially be used as a cost-effective, less burdensome, and easy to implement method in prevention of oral mucositis.

Preparation and Evaluation of a Powdered Rebamipide Mouthwash as In-Hospital Formulation: Considering Dispersion before Use in Patients. Pharmaceutics 2021; 13:pharmaceutics13111848.

Abstract
In Japan, rebamipide (RB) mouthwash (RB-MW) for oral mucositis induced by cancer chemotherapy has been prepared using in-hospital formulation. Usually, RB-MW is prepared by dispersing crushed commercial RB tablets in the dispersion medium; however, uniformity is difficult to obtain due to low solubility. The current study aims is to prepare homogenously dispersed formulations using the fine particles of crushed tablets by a method that is convenient for hospital use. Commercial RB tablets were pre-milled at different milling times as "RB-Ts". A ground mixture was then prepared by co-grinding the RB-Ts with HPC-L or PVP K30 via a benchtop ball milling machine (MM400). The physicochemical properties of samples were evaluated for PXRD, FTIR, turbidity, particle size, and solubility. Although the milling of RB tablets decreased the crystallinity, the length of milling time did not affect them. In contrast, grinding using MM400 significantly decreased RB crystallinity; their PXRD patterns showed a halo, suggesting the amorphization of RB crystals by grinding. Although solubility and turbidity seemed to be affected by the type of polymer rather than the particle size, every ground mixture showed high dispersibility. Thus, grinding the RB-Ts with polymers appeared to be the most promising way to obtain stable dispersion as an in-hospital formulation.

Abstract
Background Effective postoperative analgesia is needed to prevent the negative effects of postoperative pain on patient outcomes. To compare the effectiveness of hydromorphone hydrochloride and sufentanil, combined with flurbiprofen axetil, for postoperative analgesia in pediatric patients. Methods This prospective randomized controlled trial included 222 pediatric patients scheduled for repair of a structural congenital malformation under general anesthesia. Patients were randomized into 3 groups: hydromorphone hydrochloride 0.1 mg/kg (H1), hydromorphone hydrochloride 0.2 mg/kg; (H2) or sufentanil 1.5 µg/kg (S). Analgesics were diluted in 0.9% saline to 100 ml and infused continuously at a basic flow rate of 2 mL per h. The primary outcome measure was the Face, Legs, Activity, Cry, and Consolability (FLACC) pain score. Secondary outcomes included heart rate (HR), respiration rate (RR), SpO2, Ramsay sedation scores, scores on the Paediatric Anaesthesia Emergence Delirium (PAED) scale, adverse reactions, parent satisfaction with analgesia. Results The FLACC score was significantly lower in H1 and H2 groups compared to S. The Ramsay sedation score was significantly higher in H1 and H2 groups compared to S. Recovery time was shorter in H1 group compared to patients H2 group or S group. There were no significant differences in the PAED scale, HR, RR, SpO2, adverse reactions, satisfaction of parents with analgesia, or length and cost of hospital stay. Conclusions Hydromorphone hydrochloride is a more effective analgesic than sufentanil for postoperative pain in pediatric patients following surgical repair of a structural congenital malformation, however, hydromorphone hydrochloride and sufentanil had similar safety profiles in this patient population.

Abstract
Cancer therapy-induced oral mucositis (CTIOM) can cause intolerable oral pain resulting in difficulty in chewing, swallowing and speaking. Thus, leading to patients requiring aggressive measures, such as parenteral feeding, the placement of gastric feeding tubes and discontinuation of oncologic treatments. Although, pain is the debilitating symptom, current efforts seem to focus independently in the histological damage, not in pain and symptom care. Current strategies for managing pain from CTIOM entail maintaining oral hygiene and the use of oral rinses, topical anesthetics, prophylactic antimicrobials and systemic analgesics such as opioids. Novel therapies, such as methylene blue oral rinse, are being investigated, with positive outcomes. Therefore, there is a need to identify treatment modalities for pain of CTIOM. Ideally, this should be noninvasive, safe and cost-effective, while providing sustained analgesia.

Abstract
Background Radical surgery for colorectal cancer, associated with moderate to severe postoperative pain, needs multimodal analgesia with opioid for analgesia. Despite considerable advancements, the psychological implications and other side effects with opioid remain substantially unresolved. This study aimed to investigate the impact on mood, side effects relative to opioid, and recovery of the patients with hydromorphone or sufentanil intravenous patient-controlled analgesia (IV-PCA) in a multimodal perioperative analgesia regimen undergoing radical surgery for colorectal cancer. Methods Eighty patients undergoing elective laparoscopic or open radical surgery for colorectal cancer under general anesthesia were randomized to receive postoperative IV-PCA with either sufentanil (group S) or hydromorphone (group H). All patients received additionally flurbiprofen axetil 50 mg 30 min before the end of surgery and wound infiltration with 10 ml of 0.75% ropivacaine at the end of surgery. The primary endpoint was mood changes at 48 and 96 h after surgery. The secondary endpoints were the incidence of opioid-related adverse effects, recovery results and patient satisfaction after surgery. Results Seventy-two patients completed the study finally. There were no significant differences between the two groups with respect to preoperative parameters, surgical and anesthetic characteristics (P > 0.05). No obvious significant differences were observed in VAS score (at rest and during mobilization) and rescue analgesics use (P > 0.05). Compared with group S, the anger scores in the group H at 48 h and 96 h after surgery were significantly lower (P = 0.012 and 0.005; respectively), but the incidences of pruritus and nausea were higher (P = 0.028 and 0.008; respectively). There were no significant differences in the incidences of vomiting, respiratory depression, dizziness, Ramsay score, and hemodynamic changes between the two groups (P > 0.05). Moreover, there were no significant differences in the time to gastrointestinal recovery, time to drainage tube removal, time to walk, hospital stay after surgery and patient satisfaction between the two groups (P > 0.05). Conclusions Under the similar analgesia effect with different opoiods postoperatively, hydromorphone IV-PCA resulted in an improved mood, however, a higher occurrence of pruritus and nausea while compared to sufentanil IV-PCA in a multimodal perioperative analgesia regimen. Both regimens of opioid with IV-PCA may serve as promising candidates for good postoperative pain management, and provide with similar postoperative recovery for the patients undergoing radical surgery for colorectal cancer. Trial registration This study was registered with the Chinese Clinical Trial Registry on September 20, 2015 (URL: http://www.chictr.org.cn. Registry number: ChiCTR-IPR-15007112).

Abstract
Anticancer drug-induced stomatitis develops in 30% to 40% of cancer cases that undergo chemotherapy. However, medications for this condition are not commercially available in Japan. Upon obtaining approval of the ethics committee, a mouthwash containing rebamipide as the active ingredient (rebamipide mouthwash) was administered to one inpatient and four outpatients, who had developed stomatitis caused by cancer chemotherapy. Starting from 14 d after the administration of the rebamipide mouthwash, the patients scored a stomatitis survey on oral state, pain level, and diet and recorded the number of times they gargled, as well as any stomatitis observations, in a stomatitis diary. The total scores for the points for each of the three types of survey sections were classified into Grades 0 to 4 and evaluated as a stomatitis evaluation score (SES). The SES became "0" in three out of the five patients within 14 d of treatment. No change in SES was found in one patient. In the remaining patients, SES became "0" once but increased again later. Using image analysis software (ImageJ), the area at which the stomatitis was observed was measured. When comparing SES and change in the area in patients who agreed to participate, gradual reductions in the extent of stomatitis was observed even during the period when SES did not change. Having patients fill in an observation chart was effective for grasping changes in symptoms in outpatients.

Abstract
Objective: To discuss the historical basis and limitations of opioid conversion tables, review the relevant literature, and establish an evidence-based equianalgesic dose ratio (EDR) table for performing conversions in the acute care setting. Data Sources: Articles were identified through searches of MEDLINE (1966–January 2007) using the key words opioid, tolerance, conversion, dose, equianalgesic, equipotent, acute care, morphine, hydromorphone, fentanyl, methadone, and oxycodone. Additional references were located through a review of the bibliographies of articles cited and references cited in conversion tables. Study Selection and Data Extraction: All data sources identified were evaluated, and all information deemed relevant was included, with the exception of case series and case reports when higher level evidence was available. Data Synthesis: Opioid conversion tables are published in major textbooks, medical references, national guidelines, and review articles. Some conversion tables do not accurately reflect the dose ratios for which evidence is available. There is marginal evidence-based clinical data to support the dose ratios cited in these tables, particularly in the acute care setting where the clinical status of patients often changes rapidly. The barriers when performing route and opioid-to-opioid conversions in the acute care setting are formidable, but EDRs are provided, based on the best available evidence. Conclusions: In the acute care setting, calculation of dose ratios for opioids, based solely on opioid conversion tables, is an oversimplification of pain management, with a potential for adverse consequences. The calculation of EDRs is one step in an interdisciplinary process that must take into account patient- and institution-specific factors.

Abstract
Severe stomatitis caused by chemotherapy and radiotherapy is accompanied by severe pain and results in a poor quality of life. We used a spray preparation of indomethacin (IM; 0.25% IM dissolved in phosphate buffer, pH 7.4), a nonsteroidal anti-inflammatory drug (NSAID) to control the pain associated with stomatitis at the University of Tsukuba Hospital. This review specifically aimed to collect information on the use of the IM spray preparation, from our previous studies, to facilitate its proper use in a hospital setting. On studying the stability of the IM spray preparation, we concluded that the preparation should be kept in the refrigerator for daily use, and that it can be stored for at least 2 months at 4°C, and for 24 months at -20°C. To evaluate the efficacy of the IM spray preparation, we retrospectively surveyed its analgesic effects. Using the 10-grade Visual Analogue Scale in 23 patients, we found that pain associated with stomatitis was reduced from 10 to 4.7 after application of the spray. In conclusion, our study results on the stability and efficacy of the IM spray preparation have led to the proper use of the spray in cancer patients with stomatitis caused by chemotherapy and radiotherapy.

Abstract
BACKGROUND Hydromorphone is a potent μ-opioid selective agonist that has an onset time within 5 minutes and reaches peak effect between 10 and 20 minutes. However, it may show immediate analgesic effect to rocuronium-induced pain because of its peripheral analgesic property and also may attenuate noxious stimuli from tracheal intubation during induction. The opioid receptors are known to be present in peripheral sensory nerve terminals as well as in the dorsal root ganglion and the central terminal of primary afferent nerves. Therefore, we hypothesized that hydromorphone may be considered a potent pretreatment or adjuvant drug during the induction of anesthesia with its peripherally and centrally mediated analgesia. OBJECTIVE The aim of this study was to compare the effects of pretreatment with hydromorphone in reducing rocuronium-induced withdrawal movements and hemodynamic changes during tracheal intubation with the effects of fentanyl and normal saline. METHODS In this double-blind, randomized, controlled study, consecutive adult patients aged 20 to 70 years who were scheduled to undergo general anesthesia for elective gastric or colorectal surgery at the Samsung Seoul Hospital (Seoul, Republic of Korea) were randomly assigned to receive 5 mL hydromorphone 0.03 mg/kg or fentanyl 2 μg/kg or normal saline. Thirty seconds after administering the study drug, anesthesia was induced with 2.5% thiopental sodium 5 mg/kg. After loss of consciousness, rocuronium 0.6 mg/kg was injected and immediate withdrawal movements were recorded. Two minutes after rocuronium injection, tracheal intubation was performed and hemodynamic changes were observed. RESULTS A total of 194 patients were enrolled, with 65 in the hydromorphone group, 67 in the fentanyl group, and 62 in the saline group. The overall incidence of withdrawal movements was significantly lower in the hydromorphone group (2 patients; 3.1%) and the fentanyl group (5 patients; 7.5%) (both, P < 0.001) than in the saline group (36 patients; 58.1%). The mean arterial pressure (MAP) and heart rate (HR) after intubation (median [interquartile range]) in the fentanyl group (101.5 [84-115] mm Hg; 93.5 [82-102] beats per minute [bpm]) and the hydromorphone group (93.0 [83-106] mm Hg; 90.0 [86.3-93.6] bpm) were significantly lower than these measures in the saline group (111.5 [105-123] mm Hg; 103.5 [96-113] bpm) (fentanyl group MAP and HR, P < 0.001; hydromorphone group MAP and HR, P < 0.001). CONCLUSIONS Pretreatment with hydromorphone and fentanyl may have similar effectiveness in reducing withdrawal movements in response to rocuronium injection pain and inducing immediate general anesthesia.

Abstract
BACKGROUND There is currently no instrument to systematically assess the range of symptoms/problems and their bothersomeness in patients with chronic non-cancer pain (CNPN). Systematic assessment and prioritizing may target treatments and improve outcomes. METHODS The authors developed a checklist of symptoms and problems, the Copenhagen Symptom Checklist (CSC), presented clinically by patients. Fifty-three items representing biological, psychological and social areas were selected. Symptom/problem severity was rated on a 5-point scale anchored at 0 = 'not at all' and 4 = 'severe'. Patients ranked the five most bothersome symptoms/problems and could add five open-ended items. Patients completed the CSC after the first visit at the multidisciplinary pain centre. RESULTS One hundred and twelve consecutive patients completed the CSC. Eighty-nine percent scored pain as rather severe or very severe (score = 3 plus score = 4), followed by reduction in physical activity (67%), fatigue (66%) and sleep disturbance (53%). Pain and fatigue, but not reduction in physical activity, were given highest priority. Cognitive problems were important to a third of the patients. Depressive symptoms, cognitive problems and worry explained 17.5% of the total variance. Patients filled in the CSC without important loss of information, but a minority prioritized more than three areas or used the free text alternative. CONCLUSIONS Patients prioritized pain and fatigue as the most burdensome symptoms, but reduction in physical activity and sleep problems were also highly ranked. Patients were positive to the idea of symptom reporting; however, the 53-item number in this version of CSC is larger than may be necessary.

Abstract
PURPOSE The aim of this project was to develop clinical practice guidelines on the use of antimicrobials, mucosal coating agents, anesthetics, and analgesics for the prevention and management of oral mucositis (OM) in cancer patients. METHODS A systematic review of the available literature was conducted. The body of evidence for the use of each agent, in each setting, was assigned a level of evidence. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, or no guideline possible. RESULTS A recommendation was developed in favor of patient-controlled analgesia with morphine in hematopoietic stem cell transplant (HSCT) patients. Suggestions were developed in favor of transdermal fentanyl in standard dose chemotherapy and HSCT patients and morphine mouth rinse and doxepin rinse in head and neck radiation therapy (H&N RT) patients. Recommendations were developed against the use of topical antimicrobial agents for the prevention of mucositis. These included recommendations against the use of iseganan for mucositis prevention in HSCT and H&N RT and against the use of antimicrobial lozenges (polymyxin-tobramycin-amphotericin B lozenges/paste and bacitracin-clotrimazole-gentamicin lozenges) for mucositis prevention in H&N RT. Recommendations were developed against the use of the mucosal coating agent sucralfate for the prevention or treatment of chemotherapy-induced or radiation-induced OM. No guidelines were possible for any other agent due to insufficient and/or conflicting evidence. CONCLUSION Additional well-designed research is needed on prevention and management approaches for OM.

Abstract
Abstract
Background and aim
The present study reports on chronic non-cancer patients who were referred to a private pain clinic, according to a waiting time guarantee and treated within one month from referral. Based on evaluation by members of the multidisciplinary staff at our pain clinic a pain management program could be offered individually or as group therapy.
Methods
Health related quality of life, psychometric tests, use of pain medication; socio-economic status and number of consultations in general practice were recorded at referral to the clinic and by postal questionnaires at follow-up 21 months later. The primary treatment outcome (treatment success) was defined as an improvement of at least 40 points in the physical component and/or the mental component of SF-36 from baseline to follow-up. Secondary outcome measures were changes in Beck’s Anxiety Inventory and Beck’s Depression Inventory, use of analgesics, work status and transfer income and number of consultations at the GP’s office due to the chronic pain condition.
Results
A total of 306 patients were included: 141 were treated individually and 165 were treated in groups. At follow-up, data were obtained from 189 patients (62%). Comparing baseline to follow-up data, 62% of group treated patients were treated successfully, compared with 41% of individually treated patients. Anxiety and depression were significantly improved in group treated patients but not in those treated individually. significantly more patients had work income (and less patients transfer income) among group treated, compared with individually treated. At follow-up use of antidepressants and anticonvulsants was increased whereas use of tranquilizers and strong opioids was decreased in all patients. Number of consultations at their GPs due to chronic pain was significantly reduced in all patients.
Conclusions
Multidisciplinary treatment in a private pain clinic seems to have a long-term effect in relation to biological, psychological and social aspects of the chronic pain condition. Treatments based on group therapy may offer better results than individual treatment courses.
Implications
The effect of group therapy should be explored further.

Abstract
OBJECTIVE Solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients are at risk of several diseases, principally attributable to immunosuppression. This global overview of SOT/HSCT-associated orofacial diseases is aimed at providing a practical instrument for the oral healthcare management of SOT/HSCT recipients. METHODS Literature search was made through MEDLINE. The associations between orofacial diseases and SOT/HSCT were assessed using observational studies and case series and were classified into 'association', 'no association', and 'unclear association'. RESULTS Lip/oral cancers, drug-induced gingival overgrowth (DIGO), infections, including hairy leukoplakia and, less frequently, post-transplantation lymphoproliferative disorders (PTLDs) and oral lichenoid lesions of graft-versus-host disease (GVHD), were associated with SOT. Lip/oral cancers, GVHD, mucositis, DIGO, infections and, less frequently, PTLDs were associated with HSCT. Associations of orofacial granulomatosis-like lesions and oral mucosa-associated lymphoid tissue-type lymphoma with SOT, and of pyogenic granuloma and hairy leukoplakia with HSCT were unclear. Periodontal disease and dental caries were not associated with SOT/HSCT. For none of the local treatments was there a strong evidence of effectiveness. CONCLUSIONS Solid organ transplant/HSCT recipients are at risk of orofacial diseases. Adequate management of these patients alleviates local symptoms responsible for impaired eating, helps prevent systemic and lethal complications, and helps where dental healthcare has been neglected.

Abstract
The aim of the study was to investigate the influence of pain, sedation, pain medications and socio-demographics on cognitive functioning in chronic non-malignant pain patients. Chronic non-malignant pain patients (N=91) treated in a multidisciplinary pain centre were compared with age and sex matched healthy volunteers (N=64). Furthermore four subgroups of patients were examined: Group 1 (N=21) received no pain medications, group 2 (N=19) were in long-term oral opioid treatment, group 3 (N=18) were treated with antidepressants and/or anticonvulsants and group 4 (N=33) were treated with a combination of long-term oral opioids and antidepressants and/or anticonvulsants. Assessments comprised pain (PVAS) and sedation (SVAS), Continuous Reaction Time (CRT) testing for sustained attention, Finger Tapping Test (FTT) testing for psychomotor speed, Paced Auditory Serial Addition Task (PASAT) testing for information processing and working memory and Mini Mental State Examination (MMSE). CRT and FTT were impaired in the total patient sample. Treatment with opioids was associated with poorer performance of PASAT. High scores of PVAS and SVAS were associated with poor performance of PASAT and CRT, respectively. MMSE seems to be too insensitive for detecting the milder forms of cognitive impairment found in chronic non-malignant patients.

Validation and usefulness of the Danish version of the Pain Medication Questionnaire in opioid-treated chronic pain patients. Acta Anaesthesiol Scand 2011; 55:1231-8.

Abstract
BACKGROUND Addiction is a feared complication of long-term opioid therapy for chronic pain patients. A screening tool to assess the potential risk of addiction may be helpful. METHODS The Pain Medication Questionnaire (PMQ) was translated into Danish by a 'forward' and 'backward' translation procedure. Patients with chronic non-cancer pain and cancer pain treated at a tertiary pain center were screened for addiction using Portenoy's criteria and invited to answer the Danish version of the PMQ. RESULTS Two hundred nine patients participated in the study. PMQ was able to discriminate between addicted and non-addicted patients. Patients with high PMQ scores indicating a risk of addiction drank more alcohol, smoked more tobacco, used higher doses of morphine, had a higher anxiety and depression score, and had poorer mental health. Using a cut-off score of 22, the PMQ had a sensitivity of 82%, but the specificity at this cut-point was 56%, indicating a risk of false positive cases. Convergent and discriminant validity were confirmed by correlation with opioid doses, alcohol and tobacco use, anxiety and depression scores, and inverse correlation with mental health and social role. Test-retest showed a very strong correlation. Cronbach's alpha for internal consistency was 0.61. Ten components were found to have eigenvalues above 1.0, confirming the multidimensional structure of the questionnaire. CONCLUSIONS The PMQ may assist physicians in addiction risk assessment and stratification when treating chronic pain patients with opioids. PMQ is not a diagnostic tool and should only be used as an indicator for possible addiction problems.

Abstract
We have conducted a meta-analysis of the clinical effects of morphine and hydromorphone to compare their benefit in analgesia. Embase and Medline were searched with an end-date of June 2009 for randomized, controlled trials or observational studies that addressed comparative analgesic and side-effects or particular side-effects. Two researchers independently identified included studies and extracted the data. Estimates of opioid effects were combined by using a random-effects model. Meta-analysis of eight studies suggested that hydromorphone (494 patients) provides slightly better (P=0.012) clinical analgesia than morphine (510 patients). The effect-size was small (Cohen's d=0.266) and disappeared when one study was removed, although the advantage of hydromorphone was more evident in studies of better quality (Jadad's rating). Side-effects were similar, for example, nausea (P=0.383, nine studies, 456 patients receiving hydromorphone and 460 morphine); vomiting (P=0.306, six studies, 246 patients receiving hydromorphone and 239 morphine); or itching (P=0.249, eight studies, 405 patients receiving hydromorphone, 410 morphine). This suggests some advantage of hydromorphone over morphine for analgesia. Additional potential clinical pharmacological advantages with regard to side-effects, such as safety in renal failure or during acute analgesia titration, are based on limited evidence and require substantiation by further studies.

Abstract
The aim of this systematic review is to evaluate the scientific evidence for the efficacy and side effects of hydromorphone in the management of moderate to severe cancer pain. Randomized and non-randomized clinical trials, reporting data on efficacy and/or side effects of hydromorphone, were identified. Thirteen eligible studies, involving 1208 patients, were selected. Seven studies compared hydromorphone with other opioids (five with morphine, one with oxycodone and one with fentanyl and buprenorphine) and five of them were randomized controlled trials (RCTs). Most of the studies were conducted on patients already receiving opioid treatment, often at stabilized doses, and most had methodological limitations. The RCTs comparing hydromorphone with morphine and oxycodone showed similar analgesic results, while the comparison of side effects showed minor differences, not consistent across studies. Due to clinical and methodological heterogeneity of the studies, a meta-analysis was not performed. In conclusion there is evidence to support the efficacy and tolerability of hydromorphone for moderate to severe cancer pain as an alternative to morphine and oxycodone, while there is no evidence to demonstrate its superiority or inferiority in comparison with morphine as the first choice opioid for the same indication.

Nausea and vomiting after surgery under general anesthesia: an evidence-based review concerning risk assessment, prevention, and treatment. DEUTSCHES ARZTEBLATT INTERNATIONAL 2010; 107:733-41.

Abstract
BACKGROUND The German-language recommendations for the management of postoperative nausea and vomiting (PONV) have been revised by an expert committee. Major aspects of this revision are presented here in the form of an evidence-based review article. METHODS The literature was systematically reviewed with the goal of revising the existing recommendations. New evidence-based recommendations for the management of PONV were developed, approved by consensus, and graded according to the scheme of the Scottish Intercollegiate Guidelines Network (SIGN). RESULTS The relevant risk factors for PONV include female sex, nonsmoker status, prior history of PONV, motion sickness, use of opioids during and after surgery, use of inhalational anesthetics and nitrous oxide, and the duration of anesthesia. PONV scoring systems provide a rough assessment of risk that can serve as the basis for a risk-adapted approach. Risk-adapted prophylaxis, however, has not been shown to provide any greater benefit than fixed (combination) prophylaxis, and PONV risk scores have inherent limitations; thus, fixed prophylaxis may be advantageous. Whichever of these two approaches to manage PONV is chosen, high-risk patients must be given multimodal prophylaxis, involving both the avoidance of known risk factors and the application of multiple validated and effective antiemetic interventions. PONV should be treated as soon as it arises, to minimize patient discomfort, the risk of medical complications, and the costs involved. CONCLUSION PONV lowers patient satisfaction but is treatable. The effective, evidence-based measures of preventing and treating it should be implemented in routine practice.

Abstract
BACKGROUND Treatment of cancer is increasingly effective but associated with short and long term side effects. Oral side effects, including oral mucositis (mouth ulceration), remain a major source of illness despite the use of a variety of agents to treat them. OBJECTIVES To assess the effectiveness of interventions for treating oral mucositis or its associated pain in patients with cancer receiving chemotherapy or radiotherapy or both. SEARCH STRATEGY Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 1 June 2010), CENTRAL via The Cochrane Library (to Issue 2, 2010), MEDLINE via OVID (1950 to 1 June 2010), EMBASE via OVID (1980 to 1 June 2010), CINAHL via EBSCO (1980 to 1 June 2010), CANCERLIT via PubMed (1950 to 1 June 2010), OpenSIGLE (1980 to 1 June 2010) and LILACS via the Virtual Health Library (1980 to 1 June 2010) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. SELECTION CRITERIA All randomised controlled trials comparing agents prescribed to treat oral mucositis in people receiving chemotherapy or radiotherapy or both. Outcomes were oral mucositis, time to heal mucositis, oral pain, duration of pain control, dysphagia, systemic infection, amount of analgesia, length of hospitalisation, cost and quality of life. DATA COLLECTION AND ANALYSIS Data were independently extracted, in duplicate, by two review authors. Authors were contacted for details of randomisation, blindness and withdrawals. Risk of bias assessment was carried out on six domains. The Cochrane Collaboration statistical guidelines were followed and risk ratio (RR) values calculated using fixed-effect models (less than 3 trials in each meta-analysis). MAIN RESULTS Thirty-two trials involving 1505 patients satisfied the inclusion criteria. Three comparisons for mucositis treatment including two or more trials were: benzydamine HCl versus placebo, sucralfate versus placebo and low level laser versus sham procedure. Only the low level laser showed a reduction in severe mucositis when compared with the sham procedure, RR 5.28 (95% confidence interval (CI) 2.30 to 12.13).Only 3 comparisons included more than one trial for pain control: patient controlled analgesia (PCA) compared to the continuous infusion method, therapist versus control, cognitive behaviour therapy versus control. There was no evidence of a difference in mean pain score between PCA and continuous infusion, however, less opiate was used per hour for PCA, mean difference 0.65 mg/hour (95% CI 0.09 to 1.20), and the duration of pain was less 1.9 days (95% CI 0.3 to 3.5). AUTHORS' CONCLUSIONS There is weak and unreliable evidence that low level laser treatment reduces the severity of the mucositis. Less opiate is used for PCA versus continuous infusion. Further, well designed, placebo or no treatment controlled trials assessing the effectiveness of interventions investigated in this review and new interventions for treating mucositis are needed.

Abstract
Patient Controlled Analgesia is a useful technic to deliver morphine analgesia via a programmable pump: the patient himself choose to self-administer a bolus dose (usually morphine); the dosage is calculated and prescribed according to the level of pain, limits of dose and period of interdiction are planned. After initial bolus to decrease severe pain (titration), the patient from the age of 6 years can manage his analgesia. This method of administration of the analgesic allows to adapting at best the posology of morphine to the level of pain and has a high safety level. A continuous flow can be prescribed if the pain is severe, but requires a greater level of surveillance of the essential parameters: breath and sedation, in order to avoid any overdose. As for any morphine analgesia, the unwanted effects must be prevented or treated. If the child cannot handle the pump (young age, handicap, tiredness) the nurse or sometimes the relative can activate the delivery of bolus after a specific training. The education of the relatives (parents) and the child is essential. This simple and efficacious method of analgesia requires an adequate training of the nursing staff.

Abstract
Opioid rotation refers to a switch from one opioid to another in an effort to improve the response to analgesic therapy or reduce adverse effects. It is a common method to address the problem of poor opioid responsiveness despite optimal dose titration. Guidelines for opioid rotation are empirical and begin with the selection of a safe and reasonably effective starting dose for the new opioid, followed by dose adjustment to optimize the balance between analgesia and side effects. The selection of a starting dose must be based on an estimate of the relative potency between the existing opioid and the new one. Potency, which is defined as the dose required to produce a given effect, differs widely among opioids, and among individuals under varying conditions. To effectively rotate from one opioid to another, the new opioid must be started at a dose that will cause neither toxicity nor abstinence, and will be sufficiently efficacious in that pain is no worse than before the change. The estimate of relative potency used in calculating this starting dose has been codified on "equianalgesic dose tables," which historically have been based on the best science available and have been used with little modification for more than 40 years. These tables, and the clinical protocols used to apply them to opioid rotation, may need revision, however, as the science underlying relative potency evolves. Review of these issues informs the use of opioid rotation in the clinical setting and defines key areas for future research.

Abstract
BACKGROUND/OBJECTIVE We investigated the efficacy and safety of transdermal fentanyl for severe mucositis pain caused by chemotherapy. METHODS Thirty-two patients who had moderate to severe pain using the Numeric Rating Scale (NRS) were enrolled in this study. The analgesic effect, quality of life and side effects were evaluated after the administration of transdermal fentanyl. RESULTS The median NRS score was reduced from 6 (range 4 - 9) before treatment to 4 (range 0 - 9), 2.5 (range 0 - 8), 2 (range 0 - 8), 2 (range 0 - 6) and 0 (range 0 - 5) on days 3, 5, 7, 10 and 15, respectively, after treatment (p < 0.001). The patients' quality of life also improved significantly (p < 0.01). The side effects of treatment were mild, and disappeared within several days. CONCLUSIONS Transdermal fentanyl is an effective, convenient and well-tolerated treatment for severe mucositis pain caused by chemotherapy that can improve patients' quality of life.

Abstract
The field of high-dose therapy and SCT has made many advances in the past several years and the success rates have been steadily increasing as newer therapies emerge and improvements in supportive care continue to improve patient survival and cure rates. There still remains a mortality risk for high-dose therapy and the need for palliative care becomes more apparent as the focus also incorporates quality of life in all facets of cancer treatment and care. This paper reports on the lack of literature available on palliative care into the BMT and explores areas of future research in the integration of these two fields of medicine.

Abstract
PURPOSE Coherent clinical care depends on answering a basic question: is a patient getting worse, getting better, or staying about the same? This can prove surprisingly difficult to answer confidently. Patient-reported outcomes (PROs) could potentially help by providing quantifiable evidence. But quantifiable evidence is not necessarily good evidence, as this article details. METHOD The fundamental mandate of measurement requires that errors in making an assessment be smaller than the distinctions to be measured. This mandate implies that numerical observations of patients may be poor measurements. RESULTS Individual assessments require high measurement precision and reliability. Group-averaged comparisons cancel out measurement error, but individual PROs do not. Individual PROs generate numbers, to be sure, but the numbers may fall short of what we should demand of measurements. When typical errors of measurement are large, it is not possible to answer confidently even the modest question of whether a patient is getting worse or getting better. CONCLUSION This article explains some theory behind the mandate of measurement, provides several examples based on clinical research, and suggests strategies to measure and monitor individual patient outcomes more precisely. These include more frequent low-burden assessments, more realistic confidence levels, and strengthened measurement that integrates population data.

Abstract
BACKGROUND Pain is the most common discomfort experienced by children undergoing major operations. It is most often not adequately treated because of inexperience and unfounded fears related to the use of opioid drugs. In adults, patient-controlled analgesia (PCA) is widely administered, while in children, its use with opioid drugs is still under evaluation for safety and efficacy. OBJECTIVES The objective of the study is to evaluate the safety and efficacy of an opioid drug (fentanil) administered by PCA associated with a sedative-adjuvant drug (midazolam) administered by continuous infusion in children having undergone major neurosurgical procedures. MATERIALS AND METHODS Sixteen children with moderate to severe postoperative pain were treated with fentanil by PCA (booster doses of 1 microg/kg) plus continuous infusion of midazolam (2 microg/kg per min) by an intravenous route. To evaluate safety and efficacy of this analgesic protocol, different subjective and objective parameters were monitored at 4-h intervals. In addition, patients' satisfaction was assessed by a questionnaire at the end of the treatment. MAIN RESULTS All children experienced a good degree of analgesia and did not require any other analgesic drug during the treatment. Both subjective and objective parameters improved after starting pain-relieving treatment, and no major side effects occurred. The analysis of the answers of the questionnaire administered to the children showed a high grade of satisfaction. CONCLUSIONS PCA with fentanil plus continuous infusion of midazolam is a safe and efficacious method for analgesia in children with moderate to severe postoperative neurosurgical pain. The association of midazolam to fentanil also contributes to control anxiety and stress in this subset of patients and does not show any important side effects.

Abstract
Oral mucositis (OM) is an extremely debilitating side effect of certain high-dose chemotherapy and radiotherapy regimens. It is especially prevalent in patients with haematological malignancies who undergo myeloablative therapy and autologous haematopoietic stem cell transplantation (HSCT). Severe erosion of the lining of the oral cavity can make patients' everyday activities, including eating, drinking, swallowing, and talking, difficult or even impossible. Palifermin (Kepivance) was approved in Europe in 2005 for both prevention and treatment of this painful condition. It works at the epithelial level to help protect cells in the mouth and throat from the damage caused by chemotherapy and radiation, and to stimulate growth and development of new epithelial cells to build up the mucosal barrier. In the pivotal clinical trial, palifermin reduced the incidence, severity, and duration of severe OM. Palifermin was also well-tolerated; common adverse reactions reported included rash, pruritus, erythema, edema, pain, fever, arthralgia, mouth or tongue disorders, and taste alteration. In this article, nurses who are skilled in caring for patients undergoing HSCT review their clinical experience with palifermin, sharing practical advice about its reconstitution, dosing, and administration. By familiarising themselves with the use of palifermin, nurses can influence a shift in clinical practice away from OM symptom management to the more satisfactory situation of protecting patients against severe OM.

Abstract
Cancer-associated pain is extremely common and is associated with significant physical and psychological suffering. Unfortunately, pain associated with cancer or its treatment is frequently under-treated, probably due to several factors, including phobia of opioids, under-reporting by patients, and under-diagnosis by healthcare workers. The most common etiology of cancer pain is local tumor invasion (primary or metastatic), involving inflammatory and neuropathic mechanisms; these have been reviewed in Part I. As malignant disease advances, pain usually becomes more frequent and more intense. Additional expressions of orofacial cancer pain include distant tumor effects, involving paraneoplastic mechanisms. Pain secondary to cancer therapy varies with the treatment modalities used: Chemo-radiotherapy protocols are typically associated with painful mucositis and neurotoxicity. Surgical therapies often result in nerve and tissue damage, leading, in the long term, to myofascial and neuropathic pain syndromes. In the present article, we review the clinical presentation of cancer-associated orofacial pain at various stages: initial diagnosis, during therapy (chemo-, radiotherapy, surgery), and in the post-therapy period. As a presenting symptom of orofacial cancer, pain is often of low intensity and diagnostically unreliable. Diagnosis, treatment, and prevention of pain in cancer require knowledge of the presenting characteristics, factors, and mechanisms involved.

Abstract
BACKGROUND Treatment of cancer is increasingly effective but associated with short and long term side effects. Oral side effects, including oral mucositis (mouth ulceration), remain a major source of illness despite the use of a variety of agents to treat them. OBJECTIVES To assess the effectiveness of interventions for treating oral mucositis or its associated pain in patients with cancer receiving chemotherapy or radiotherapy or both. SEARCH STRATEGY Computerised searches of Cochrane Oral Health Group's Trials Register; Cochrane Pain, Palliative and Supportive Care Group's Trials Register; CENTRAL; MEDLINE and EMBASE were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. Date of the most recent searches June 2006: CENTRAL (The Cochrane Library 2006, Issue 2). SELECTION CRITERIA All randomised controlled trials comparing agents prescribed to treat oral mucositis in people receiving chemotherapy or radiotherapy or both. Outcomes were oral mucositis, time to heal mucositis, oral pain, duration of pain control, dysphagia, systemic infection, amount of analgesia, length of hospitalisation, cost and quality of life. DATA COLLECTION AND ANALYSIS Data were independently extracted, in duplicate, by two review authors. Authors were contacted for details of randomisation, blindness and withdrawals. Quality assessment was carried out on these three criteria. The Cochrane Oral Health Group statistical guidelines were followed and risk ratio (RR) values calculated using fixed effect models. MAIN RESULTS Twenty-six trials involving 1353 patients satisfied the inclusion criteria. Four agents, each in single trials, were found to be effective for improving (allopurinol RR 3.33, 95% confidence interval (CI) 1.06 to 10.49; granulocyte macrophage-colony stimulating factor RR 4.23, 95% CI 1.35 to 13.24; immunoglobulin RR 1.81, 95% CI 1.24 to 2.65; human placentral extract RR 4.50, 95% CI 2.29 to 8.86) or eradicating mucositis (allopurinol RR 19.00, 95% CI 1.17 to 307.63). Three of these trials were rated as at moderate risk of bias and one as at high risk of bias. The following agents were not found to be effective: benzydamine HCl, sucralfate, tetrachlorodecaoxide, chlorhexidine and 'magic' (lidocaine solution, diphenhydramine hydrochloride and aluminum hydroxide suspension). Six trials compared the time to heal and mucositis was found to heal more quickly with two interventions: granulocyte macrophage-colony stimulating factor when compared to povidone iodine, with mean difference -3.5 days (95% CI -4.1 to -2.9) and allopurinol compared to placebo, with mean difference -4.5 days (95% CI -5.8 to -3.2). Three trials compared patient controlled analgesia (PCA) to the continuous infusion method for controlling pain. There was no evidence of a difference, however, less opiate was used per hour for PCA, and the duration of pain was shorter. One trial demonstrated that pharmacokinetically based analgesia (PKPCA) reduced pain compared with PCA: however, more opiate was used with PKPCA. AUTHORS' CONCLUSIONS There is weak and unreliable evidence that allopurinol mouthwash, granulocyte macrophage-colony stimulating factor, immunoglobulin or human placental extract improve or eradicate mucositis. There is no evidence that patient controlled analgesia (PCA) is better than continuous infusion method for controlling pain, however, less opiate was used per hour, and duration of pain was shorter, for PCA. Further, well designed, placebo-controlled trials assessing the effectiveness of allopurinol mouthwash, granulocyte macrophage-colony stimulating factor, immunoglobulin, human placental extract, other interventions investigated in this review and new interventions for treating mucositis are needed.

Safety and efficacy of fentanyl administered by patient controlled analgesia in children with cancer pain. Support Care Cancer 2006; 15:569-73. [PMID: 17146653 DOI: 10.1007/s00520-006-0193-8] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2006] [Accepted: 11/08/2006] [Indexed: 10/23/2022]
Abstract
BACKGROUND Pain is the most common discomfort experienced by children with cancer and occurs in almost 89% of patients in an advanced stage of the disease. It is most often not adequately treated because of inexperience and unfounded fears of analgesic treatment. In adults, patient controlled analgesia (PCA) is widely administered, while in children with moderate to severe cancer pain its use is still under evaluation for safety and efficacy. GOALS OF WORK To evaluate the efficacy and safety of fentanyl administered by PCA in children with cancer pain. MATERIALS AND METHODS Eighteen children (range 6 to 15 years) with moderate to severe pain were enrolled and treated with fentanyl by PCA plus background infusion (BI) (BI of 1 microg/kg/h with booster doses of 1 microg/kg by intravenous route). To evaluate efficacy and safety of the analgesic treatment, different subjective and objective parameters were monitored at 4-h intervals. In addition, patients' satisfaction was assessed by a questionnaire at the end of the treatment. MAIN RESULTS All children experienced a good degree of analgesia and did not require any other analgesic drug during the treatment. Both subjective and objective parameters improved after starting pain-relieving treatment and no major side effects occurred. The questionnaire administered to the children showed a high grade of satisfaction. CONCLUSIONS PCA plus BI with fentanyl administered by intravenous route is a safe and efficacious method for analgesia in children with moderate to severe cancer pain. Our policy of fentanyl-treatment did not show any major side effects.

Oral mucositis in myeloma patients undergoing melphalan-based autologous stem cell transplantation: incidence, risk factors and a severity predictive model. Bone Marrow Transplant 2006; 38:501-6.

Abstract
Melphalan-based autologous stem cell transplant (Mel-ASCT) is a standard therapy for multiple myeloma, but is associated with severe oral mucositis (OM). To identify predictors for severe OM, we studied 381 consecutive newly diagnosed myeloma patients who received Mel-ASCT. Melphalan was given at 200 mg/m2 body surface area (BSA), reduced to 140 mg/m2 for serum creatinine >3 mg/dl. Potential covariates included demographics, pre-transplant serum albumin and renal and liver function tests, and mg/kg melphalan dose received. The BSA dosing resulted in a wide range of melphalan doses given (2.4-6.2 mg/kg). OM developed in 75% of patients and was severe in 21%. Predictors of severe OM in multiple logistic regression analyses were high serum creatinine (odds ratio (OR)=1.581; 95% confidence interval (CI): 1.080-2.313; P=0.018) and high mg/kg melphalan (OR=1.595; 95% CI: 1.065-2.389; P=0.023). An OM prediction model was developed based on these variables. We concluded that BSA dosing of melphalan results in wide variations in the mg/kg dose, and that patients with renal dysfunction who are scheduled to receive a high mg/kg melphalan dose have the greatest risk for severe OM following Mel-ASCT. Pharmacogenomic and pharmacokinetic studies are needed to better understand interpatient variability of melphalan exposure and toxicity.

Abstract
BACKGROUND Breakthrough pain (BTP) has not formerly been discussed as such in chronic non-malignant pain patients referred to pain centres and clinics. The purpose of the study was to investigate the prevalence, characteristics and mechanisms of BTP in opioid-treated chronic non-malignant pain patients referred to a pain centre and to assess the short-term effects of pain treatment. METHODS Patients were assessed at referral (T(0)) and after a treatment period of 3 months (T(3)) using the visual analogue scale (VAS) of the brief pain inventory (BPI) within somatic nociceptive, neuropathic and/or visceral pain conditions, the mini mental state examination (MMSE) and the hospital anxiety and depression scale (HADS). The main treatment intervention from T(0) to T(3) was to convert short-acting oral opioids to long-acting oral opioids and to discontinue on demand and parenteral use of opioids. RESULTS Thirty-three patients were assessed at T(0) and 27 at T(3). The prevalence of BTP declined significantly from T(0) (90%) to T(3) (70.4%). Worst, least, average and current pain intensities as well as duration of BTP were significantly reduced from T(0) to T(3.) The majority of BTPs were exacerbation of background pain assumed to be of the same pain mechanisms. High average pain intensity (BPI) was significantly associated with high scores for both anxiety and depression (HADS). CONCLUSION BTP in chronic non-malignant pain patients seems to be surprisingly frequent and severe. Stabilizing the opioid regimen seems to reduce pain intensity in general as well as the intensity and duration of BTP. Average pain intensity was associated with anxiety and depression.

Safety and Efficacy of Hydromorphone as an Analgesic Alternative to Morphine in Acute Pain: A Randomized Clinical Trial. Ann Emerg Med 2006; 48:164-72. [PMID: 16857467 DOI: 10.1016/j.annemergmed.2006.03.005] [Citation(s) in RCA: 77] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2005] [Revised: 02/27/2006] [Accepted: 03/03/2006] [Indexed: 11/17/2022]
Abstract
STUDY OBJECTIVE We compare a standard weight-based dose of intravenous hydromorphone (Dilaudid) to a standard weight-based dose of intravenous morphine in adults presenting to the ED with acute severe pain. METHODS This was a prospective, randomized, double-blind, clinical trial conducted in an academic medical center. Of the 198 adult patients presenting to the ED with acute severe pain who were randomized to receive either intravenous hydromorphone at 0.015 mg/kg or intravenous morphine at 0.1 mg/kg, 191 patients had sufficient data for analysis. The main outcome measure was the difference between the 2 groups in pain reduction at 30 minutes as measured on a validated numeric rating scale. Adverse effects, pain reduction at 5 minutes and 2 hours postbaseline, and additional analgesics and antiemetics were tracked as secondary outcome measures. RESULTS The mean change of pain from baseline to 30 minutes postbaseline in patients allocated to intravenous hydromorphone was -5.5 numeric rating scale units versus -4.1 in patients allocated to intravenous morphine (difference -1.3; 95% confidence interval -2.2 to -0.5). Adverse effects were similar in both groups, with the exception of pruritus, which did not occur in patients receiving hydromorphone (0% versus 6% [difference -6%; 95% confidence interval -11% to -1%]). No patient required naloxone. CONCLUSION For the treatment of acute, severe pain in the emergency department, intravenous hydromorphone at 0.015 mg/kg represents a feasible alternative to intravenous morphine at 0.1 mg/kg.

Multidimensional measurement of fatigue in advanced cancer patients in palliative care: an application of the multidimensional fatigue inventory. J Pain Symptom Manage 2006; 31:533-41. [PMID: 16793493 DOI: 10.1016/j.jpainsymman.2005.11.012] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/01/2005] [Indexed: 10/24/2022]
Abstract
To investigate the level, dimensionality, and correlates associated with fatigue in patients receiving specialist palliative care, 278 advanced cancer patients referred to a department of palliative medicine during a 2-year period were asked to complete the Multidimensional Fatigue Inventory (MFI-20), a self-assessment questionnaire measuring five dimensions of fatigue, and the Hospital Anxiety and Depression Scale. Of 267 eligible patients, 130 (49%) participated. Mean fatigue scores (0-100 scale) were very high, especially for general fatigue (81), physical fatigue (87), and reduced activity (85). Only some of the MFI-20 subscales were significantly correlated. Fatigue was not correlated with sociodemographic factors. Depressed patients had higher scores on all five subscales except physical fatigue. Anxious patients had higher levels on the mental fatigue subscale only. The variation in fatigue explained by depression varied markedly (4%-31%) among subscales. Fatigue levels were very high in this population. The lack of significant correlation between some subscales indicates that they measure different aspects of fatigue. This is also supported by the differences in associations between fatigue subscales and depression and anxiety.
