Intrathecal cervical analgesia for cancer pain: a 12-year follow-up study in a comprehensive cancer center.

BACKGROUND: Intrathecal analgesia plays a key role for patients suffering refractory cancer pain. Nevertheless, intrathecal drug delivery systems (IDDS), requiring a cervical catheter tip implantation, have been poorly described in medical literature. AIMS: A monocentric retrospective follow-up study was designed to evaluate results of cervical IDDS for cancer pain. PATIENTS AND METHODS: From January 2010 to December 2022, all intrathecal-treated patients were prescribed a combined intrathecal analgesics regimen through a catheter placed in the cervical vertebral canal. Post-implant assessment of pain was determined using a numeric rating scale (NRS). Patients were followed via day-hospital visits and telephone calls at least monthly. Pain scores were compared using the Wilcoxon's signed rank test. RESULTS: Ninety-eight patients were included in this study; all received intrathecal treatments. Implanted patients suffered from severe pain (mean presurgical maximum numerical rating score 8.02±0.24 despite a mean 562.56±127.72 mg of oral morphine equivalent daily dose). Mean survival time after intrathecal treatment start was 208.48±67 days. Intrathecal drug delivery systems provided pain relief compared with initial pain score with a significant statistical difference after 1 week, 1 month, 2 and 3 months (p<0.01). A 50% reduction in initial pain level was achieved in 93% of cases during the first week of intrathecal implant. CONCLUSIONS: Results suggest that long-term intrathecal treatment using a multidrug regimen for cancer-related pain through cervical intrathecal catheters was suitable and safe in our study population. We demonstrated a clinically and statistically significant pain reduction in patients using mainly a percutaneous lumbar approach.

Evaluation of 8% Capsaicin Patches in Chemotherapy-Induced Peripheral Neuropathy: A Retrospective Study in a Comprehensive Cancer Center.

Introduction: Chemotherapy-induced peripheral neuropathy (CIPN) is often painful and can arise during or after the end of oncological treatments. They are mostly induced by platinum salts, taxanes, and immunotherapies. Their incidence is estimated between 19 and 85%. They can require a chemotherapy dose reduction or early termination. The European Society for Medical Oncology (ESMO) recommends high-concentration capsaicin patch (HCCP) in second line for the treatment of painful CIPN. This treatment induces a significative pain relief but only shown by low-powered studies. The objective of this study was to evaluate efficacy and tolerability of HCCP applications in CIPN. Methods: This monocentric observational retrospective real-world-data study of the CERCAN cohort took place in the Western Cancer Institute's Anaesthesiology and Pain Department at Angers, France. Independent pain physicians completed the CGIC (Clinician Global Impression of Change) for each patient who benefited from HCCP applications for painful CIPN starting from 1 January 2014 to 22 December 2021, based on the collected data after every patch application. Results: A total of 57 patients (80.7% women) was treated with HCCP for painful CIPN, and 184 applications were realized, consisting of 296 sessions. CGIC found an important or complete pain relief for 61 applications (33.2%, corresponding to 43.9% patients). We found less efficacy for platinum-salts-induced CIPN compared to others (p = 0.0238). The efficacy was significatively higher for repeated applications when HCCP was used in second line compared to third line (p = 0.018). The efficacy of HCCP was significatively higher starting the third application (p = 0.0334). HCCPs were mainly responsible for local adverse events found in 66.6% patients (65.1% burning or painful sensation, 21.1% erythema). Conclusion: HCCP applications in painful CIPN induce an important pain relief with a global satisfying tolerability.

Peripheral Neuropathic Pain Following Breast Cancer: Effectiveness and Tolerability of High-Concentration Capsaicin Patch.

PURPOSE: Data supporting the use of high-concentration capsaicin patches (HCCPs) in breast cancer (BC) patients and BC survivors (BCSs) with peripheral neuropathic pain (PNP) are limited. This observational study evaluated the effectiveness and safety of HCCP applications in BCSs/BC patients with PNP. PATIENTS AND METHODS: Data from all patients treated with HCCP in the pain department of a French comprehensive cancer centre were collected from 01-Jan-2014 to 14-Oct-2020. Independent pain specialists completed the Clinical Global Impression of Change (CGIC) for each included patient based on data extracted from patient's electronic medical record compiled by the treating pain specialist after each HCCP application. RESULTS: Patients (N=279; mean age: 59.2 years; previous history of PNP medication: 54.5%) received on average 4.1 repeated HCCP applications (1141 HCCP applications); 68.8% received HCCP as an add-on to systemic therapy and 27.9% as first-line therapy. PNP was most frequently caused by surgery (62.4%) followed by chemotherapy (11.8%) and radiotherapy (6.5%). A complete or important analgesic effect was reported at least once by 82.3% of patients. A 6.0% reported no effect at all. For post-surgical PNP existing for <12 months and >10 years an important or complete effect was observed for 70.7% and 56.0% of applications. For chemotherapy- or radiotherapy-induced PNP, this important or complete effect was observed for 52.7% and 52.3% of applications, respectively. HCCP application was associated with site reactions in 54.4% of patients (mainly burning sensation or pain, 45.9%, or erythema, 30.8%) and high blood pressure in 7.2%. CONCLUSION: This real-world chart review provides important effectiveness and safety information to clinicians when considering topical options to treat PNP in BCSs/BC patients.

First Evaluation Switching From Ropivacaine to Highly Concentrated Bupivacaine in Intrathecal Mixtures for Cancer Pain.

BACKGROUND: Intrathecal drug delivery is widely used for intractable cancer pain treatment. A combination of drugs with morphine and bupivacaine is recommended in first line therapy. In France, we use ropivacaine 10 mg/mL instead of bupivacaine 5 mg/mL, the only concentration available. Bupivacaine 40 mg/mL has been available in France only since July 2020 under temporary authorization of use. OBJECTIVES: The main objective of the study was to evaluate the safety, efficacy by pain assessment, to analyze drug dosage changes, to report adverse events (AEs) and conversion ratios switching from ropivacaine to bupivacaine. Secondary objective was to evaluate costs differences. MATERIALS AND METHODS: We conducted this retrospective follow-up monocentric study within the Institut de Cancérologie de l'Ouest (ICO) Pain Department in Angers, France. We included 14 patients aged 18 years and above, implanted with an Intrathecal Drug Delivery Systems (IDDS) for cancer pain treatment and followed up at ICO from July 2020 to February 2021 after switching from ropivacaine to bupivacaine. We used a continuous infusion mode and Bolus could be added through Personal Therapy Manager (PTM). RESULTS: The median conversion ratio between ropivacaine and bupivacaine was 0.68 (0.65; 0.69) and resulted in no significant change in numeric rating scale evaluation (p = 0.10). We observed moderate and rapidly reversible AEs such as clinical hypotension (29%) and motor block after bolus (21%). The estimated median hospital cost per day was significantly lower (p = 0.05) for the bupivacaine refills than for the last ropivacaine pump refill, decreasing from US$ 61.7 (49.6; 70.5) to US$ 50.4 (45.9; 60.4). The median reimbursement per day from the National Health Insurance (NHI) was three times lower for bupivacaine pump refill when compared to the last ropivacaine pump refill (p < 0.01), decreasing from US$ 179.10 (156.79; 182.91) to US$ 64.59 (59.85; 71.89). CONCLUSION: Switching from ropivacaine to bupivacaine in IDDS appears more efficacious while remaining just as secure, and at lower cost.

Preventing Post Dural Puncture Headache after Intrathecal Drug Delivery System Implantation Through Preventive Fibrin Glue Application: A Retrospective Study.

BACKGROUND: Cerebrospinal fluid (CSF) leakage resulting in post dural puncture headache (PDPH) is a frequent adverse effect observed after intrathecal drug delivery system (IDDS) implantation. CSF leakage symptoms negatively affect patient quality of life and can result in additional complications. Fibrin glue was used to treat CSF leakage syndrome. We developed a procedure to reduce the incidence of PDPH by preventing CSF leakage with the use of fibrin glue during surgery. OBJECTIVES: The main outcome criterion for this study was the incidence of PDPH syndrome after IDDS implantation with or without preventive fibrin glue application during the procedure. STUDY DESIGN: We designed a monocentric retrospective cohort study to compare the incidence of PDPH due to CSF leakage syndrome after lumbar puncture in patients with an implanted intrathecal pump, with or without preventive fibrin glue application during the procedure. SETTING: The study was held in the Anesthesiology and Pain department of the  Integrative Cancer Institute (ICO), Angers - France. METHODS: The study compared 2 patient cohorts over 2 successive periods. Fibrin glue was injected into the introducer needle puncture pathway after placement of the catheter immediately following needle removal. RESULTS: The no-glue group included 107 patients, whereas the glue group included 92 patients.Two application failures were observed (2.04%). Fibrin glue application results in a significant decrease in PDPH incidence, from 32.7% in the no-glue group to 10.92 % (P < 0.001) in the glue group. In regard to severity, in the no-glue group, 37.1% of PDPH syndromes were mild, 34.3% were moderate, and 28.6% were severe. In the fibrin glue group, 80% of PDPH syndromes were mild, and 20% were moderate. No severe PDPHs were reported after fibrin glue application. Duration of symptoms was also statistically shorter in the fibrin glue group (maximum of 3 days vs. 15 days in the no-glue group). In a univariate analysis, preventive fibrin glue application and age are significant to prevent PDPH. In multivariate analysis, only fibrin glue application was statistically significant (odds ratio, 0.26; P = 0.0008). No adverse effects linked to fibrin glue were observed. LIMITATIONS: The main limitation of this study is its retrospective nature. In addition, this study is from a single center with a potential selection bias and a center effect. CONCLUSIONS: The novel use of fibrin glue is promising in terms of its effect on PDPH and its safety profile. Its moderate cost and reproducibility make it an affordable and efficient technique.

Optimizing Initial Intrathecal Drug Ratio for Refractory Cancer-Related Pain for Early Pain Relief. A Retrospective Monocentric Study.

OBJECTIVE: Intrathecal (IT) drug delivery has shown its efficiency in treating refractory cancer pain, but switching opioids from the systemic to the intrathecal route is a challenging phase. Moreover, associations are widely used and recommended. Few data deal with the initial dosage of each drug. Analyzing conversion factors and initial dosages used in intrathecal therapy seems essential to decreasing the length of titration and to delivering quick pain relief to patients. METHODS: We retrospectively analyzed data from consecutive adult patients implanted with an intrathecal device for cancer pain and treated at the Institut de Cancérologie de l'Ouest, in Angers, France, for four years. The main goal was to identify factors associated with early pain relief after intrathecal drug delivery system (IDDS) implantation. RESULTS: Of the 220 IDDS-treated patients, 70 (32%) experienced early pain relief (EaPR) and 150 (68%) delayed pain relief (DePR). Performance Status stage and initial IT ropivacaine:IT morphine ratio were the variables independently associated with EaPR. The best IT ropivacaine:IT morphine ratio to predict EaPR was 5:1, with a 73% (95% confidence interval [CI] = 64.8% to 79.6%) sensitivity and a 67.1% (95% CI = 54.9% to 77.9%) specificity. EaPR subjects experienced better pain relief (-84% vs -60% from baseline pain score, P < 0.0001), shorter length of hospitalization (7 vs 10 days, P < 0.0001), and longer survival (155 vs 82 days, P = 0.004). CONCLUSIONS: Local anesthetic:morphine ratio should be considered when starting IDDS treatment. EaPR during the IT analgesia titration phase was associated with better pain relief and outcomes in patients with refractory cancer-related pain.

Genotypic and phenotypic variations in methicillin-resistant Staphylococcus aureus isolates from outpatient, inpatient and nursing homes.

PURPOSE: The epidemiological shift in MRSA distribution from healthcare-related facilities to the general population is distressing and requires continuous monitoring to manage and control the rate of incidences. METHOD: The retrospective relationship between genetic and phenotypic variability of methicillin-resistant Staphylococcus aureus (MRSA) isolates was determined in respect to the specimen source, patient location, sex and age. A total of 521 MRSA isolates were classified based on SCCmec, mec, agr, pvl and spa genetic markers using three different multiplex PCRs. RESULTS: Based on the genetic variability, the isolates were divided into 97 profiles, of which 59% belonged to only two profiles (P17 and P33). P17 was the predominate profile, harbouring SCCmecIVa, ccr2, mecB, agr1, spa413 and pvl markers. P17 was more prevalent among the younger population (average 33.9 years) from outpatient (77%) locations and wound (88%) sources. The second largest profile was P33, harbouring SCCmecII, ccr2+ccr3, mecA, agr2, spa413 and no PVL. P33 was more prevalent in the older population (average 70.7 years) and more common in females (62%) than males (38%). With respect to antibiotic resistance, P33 exhibited a high rate of resistance to penicillins, cephalosporins, fluoroquinolones and macrolides, and P17 had a lower resistance to fluoroquinolones. CONCLUSION: This report contributes to the existing understanding of evolutionary epidemiology of antibiotic resistance in MRSA. The diversity of MRSA isolates and unique environmental preferences for each profile highlights the importance of epidemiological knowledge of MRSA distribution to determine the best treatment for patients in both community and hospital settings.

[Opioid switch and change of route of administration in cancer patients treated by morphine]. / La morphine dans le cadre du changement d'opioïdes ou de voie d'administration, chez l'adulte avec une douleur due au cancer.

This paper reviewed the 2002 guidelines established by the National Federation of Cancer Centres. A group of experts nominated by the 3 French Societies involved in the treatment of cancer pain (AFSOS, SFAP, SFETD), established new guidelines ratios for morphine switching and/or changing of route of administration, in patients for whom either pain was not adequatly managed or adverse effects were unbearable. After a rapid reminder of the pharmacokinetics and metabolism properties of morphine, experts explained why the theory of opioid rotation (oxycodone, hydromorphone, fentanyl, methadone, tapentadol) using fixed equianalgesic ratios is not any more appropriate for a secure clinical practice. In the light of recent publications enhancing our knowledge on the efficacy of new drug switching ratios and for changing the route of administration of morphine, the group of experts recommended to use reconsidered switching ratios favoring security upon efficacy, to minimize overdosing and adverse effects. Consequently, after the new conversion ratio (using slow release opioids) was applied, a second titration should be done by means of normal release rescue formulations for breakthrough pain episodes. A smartphone App. OpioConvert® will be available for rapid and secure dose conversions.

Intrathecal Drug Delivery Systems for Refractory Pancreatic Cancer Pain: Observational Follow-up Study Over an 11-Year Period in a Comprehensive Cancer Center.

BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer-related death in Europe and the United States. Studies have demonstrated that patients with pancreatic cancer have a high prevalence of pain, with rates varying from 47% to 82%. Analgesia using intrathecal drug delivery systems (IDDS) has been poorly studied specifically in this population. METHODS: The IDDS for pancreatic cancer pain was a follow-up observational study designed to evaluate 11-year results of IDDS for refractory pancreatic cancer pain at the Institut de Cancérologie de L'Ouest, Paul Papin in France. Patients were followed from March 2006 to April 2017. Patients were selected for IDDS based on multidisciplinary meeting discussion. All IDDS-treated patients were prescribed a combined intrathecal analgesics regimen through a catheter placed according to painful metameric level. Postimplant assessment of pain was determined using a numerical rating scale (NRS). Patients were followed via day-hospital visits and telephone calls at least monthly until death. Pain scores were compared using the Wilcoxon signed rank test. Overall survival (OS) was estimated using the Kaplan-Meier method and compared between groups by log rank tests. RESULTS: Ninety-three patients received IDDS, and total therapy duration accounts for 10,300 IDDS days. Implanted patients suffered from severe pain before implantation (median presurgical NRS, 8 [interquartile range, 7-9]) despite a median 360 mg (260-600) oral morphine equivalent daily dose. Median OS in the whole cohort after intrathecal treatment start was 82 days (95% confidence interval, 59-95). Median OS after surgery for implantable pump was 91 days (83-111) and for external pump 27 days (20-49; P < .0001). IDDS was associated with pain relief with a significant statistical difference between preimplantation NRS pain score and 1 week (median, -6 [-7 to -4]; P < .001), 1 month (median, -5 [-6 to -3]; P < .001), and 3 months (median, -6 [-7 to -4]; P < .001). Severe pain (NRS score, ≥7) decreased from 89.2% before surgery to 4.5% after 1 week, 6.7% after 1 month, and 10.3% after 3 months of IDDS implant (P < .01). Global complications rate was low, consistent with published literature. CONCLUSIONS: Despite our study's limitations, results suggest that long-term IDDS for refractory malignant pain due to pancreatic cancer was both efficacious and safe in pancreatic cancer pain. We have demonstrated, in the largest series of IDDS for pancreatic cancer pain reported yet, a clinically and statistically significant pain reduction in patients receiving IDDS.

Patient age as a factor of antibiotic resistance in methicillin-resistant Staphylococcus aureus.

PURPOSE: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of nosocomial infections. A thorough understanding of the epidemiology and distribution of MRSA allows the development of better preventive measures and helps to control or reduce the rate of infection among the general population. METHODOLOGY: A retrospective survey was performed on 511 cases of MRSA infections from inpatient, outpatient and nursing home populations over a 12-month period. To study the relationships between two continuous quantitative variables (patient age vs resistance percentage), a simple linear regression was calculated for each antibiotic to predict the antibiotic resistance percentage with respect to patient age.Results/Key findings. The pattern of antibiotic resistance with respect to the age of patients depended on the antibiotic mode of action. Antibiotics that target DNA synthesis (i.e. fluoroquinolones) display a direct correlation with the age of patients, with higher rates of resistance among the older population, while antibiotics that target ribosomal functions (i.e. aminoglycosides) or cell wall synthesis (i.e. cephalosporin) do not display an age-dependent pattern and have a consistent degree of resistance across all age classes. CONCLUSION: Antibiotics that target DNA synthesis result in a progressively higher number of resistant isolates among the older population. The results emphasize the importance of patient age on antibiotic selection as a preventive measure to reduce the rate of resistant infections in each susceptible population. This pattern suggests that physicians should take into consideration patient age as another factor in determining the best antibiotic regiment with the aim of curtailing the emergence of newer resistant phenotypes in the future.

Epidemiology and susceptibilities of methicillin-resistant Staphylococcus aureus in Northeastern Ohio.

A retrospective survey was performed on all staphylococcal infections diagnosed by the Ashtabula County Medical Center (Ashtabula, OH) during 2006 and 2007. Of the 1,612 Staphylococcus aureus isolates evaluated for their antibiotic resistances, 947 were methicillin-resistant S aureus (MRSA). In 2007, MRSA infections reached 589 cases per 100,000 inhabitants, a 77% increase compared with 2006. The increase in MRSA infections was noticeable among youth (6-25 years old), middle-aged people (45-50 years old), and elderly people (86-90 years old). MRSA infections increased among inpatients by 58%, among outpatients by 43%, and among nursing home residents by 183%. More than 66% of MRSA infections were found among healthy people in the community with no apparent risk factors. More than 88.7% of the infections belong to only 9 profiles of antibiotic resistance indiscriminately distributed among inpatients, outpatients, and nursing home residents. This report sheds further light on the rapid spread of MRSA across Northeastern Ohio, stressing the need for better education in preventive measures and infection control at the level of community and health care settings.

[Pain and cancer Information dedicated to cancer patients and relatives]. / Douleur et cancer Informations à l'usage des personnes malades et de leurs proches.

Patient information is a major challenge for public health. It has become part of the patients' rights, in response to their need for information and involvement in medical decision-making. Since 1998, the French National Federation of Comprehensive Cancer Centres (FNCLCC) has developed an information and education program dedicated to patients and relatives: the SOR SAVOIR PATIENT program. The methodology of the program adheres to the quality criteria established for the elaboration of documents containing patient information. The SOR SAVOIR PATIENT guide Pain and Cancer aims to answer patients' questions regarding cancer specific pain and to help them become actively involved in their care. It was elaborated by a multidisciplinary workgroup, which included methodologists, one linguist, pain specialists and twenty patients and relatives. Patients' information needs and personal experience of pain were assessed using focus groups, semi-structured interviews and questionnaires. Through eight chapters, which can be read in an independent way, Pain and cancer provides key information on the causes, the mechanisms, the evaluation, the prevention and the treatment of pain. The guide also presents advices and practical tools to facilitate the assessment of the pain and the communication between patients and professionals. Finally, this guide aims to overcome ideas such as that morphine is synonymous of end of life or drug addiction, that pain is a sign of aggravation of cancer and that nurses know how to detect the pain. Intended first for the patients and their close relations, Pain and Cancer is also a useful tool for health professionals. Indeed, it presents knowledge based on the most recent recommendations developed for clinical practice. Thanks to a wide distribution of the guide to patients, their families and the professionals, we trust that this guide will facilitate dialogue around pain, and ultimately its care. This article is an abstract of the guide. The complete SOR SAVOIR PATIENT guide can be downloaded from the SOR website at: www.sor-cancer.fr.

Pain in hereditary neuromuscular disorders and myasthenia gravis: a national survey of frequency, characteristics, and impact.

The aim of our study was to evaluate pain frequency, intensity, and disability levels in a population with neuromuscular disorders (NMD). Of 862 questionnaires mailed to outpatients treated at 10 centers, 511 (300 men and 211 women) responded with answers suitable for analysis (response rate: 59.3%). Patients had Duchenne or Becker muscular dystrophy, type 1 myotonic muscular dystrophy, facioscapulohumeral muscular dystrophy, metabolic myopathy, or myasthenia gravis (MYA). The questionnaire packet included numeric scales for pain intensity and relief, the Brief Pain Inventory, the Saint Antoine Pain Questionnaire, and a scale to assess disability. More than two-thirds of the 331 patients (67.3%) suffered pain during the last three months. The mean number of days with pain was 18.4+/-15.1 days. The mean pain intensity was 4.8+/-2.5. Pain was usually diffuse (153 patients, 44%) and intermittent (228, 71%). Pain intensity varied by the NMD diagnosis; the most severe pain was observed in metabolic myopathy (13/27 patients suffered severe pain, 49%) and in MYA (16/42, 38%). Approximately three-quarters of patients had fewer than 10 days of inactivity due to pain during the last three months, and 98% had fewer than 30 days. Our study indicates that pain is frequent in hereditary muscle disorders and MYA. Mean intensity is moderate. Pain in NMD patients should be systematically assessed.

Degradation of Alyssum murale biomass in soil.

The Ni-hyperaccumulating plant Alyssum murale accumulates exceptionally high concentrations of nickel in its aboveground biomass. The reasons for hyperaccumulation remain unproven; however, it has been proposed that elemental alelopathy might be important. High-Ni leaves shed by the plant may create a "toxic zone" around the plant where germination or growth of competing plants is inhibited. The efficacy of this argument will partially depend upon the rate at which leaves degrade in soil and free metals are released, and the subsequent rate at which metals are bound to soil constituents. To test the degradation of biomass of hyperaccumulators, A. murale was grown on both high- and low-Ni soils to achieve high- (12.0 g Ni/kg) and low- (0.445 g Ni/kg) Ni biomass. Shredded leaf and stem biomass were added to a serpentine soil from Oregon that was originally used to grow high-Ni biomass and a low-Ni control soil from Maryland. Biomass Ni was readily soluble and extractable, suggesting near immediate release as biomass was added to soil Extractable nickel in soil amended with biomass declined rapidly over time due to Ni binding in soil These results suggest that Ni released from biomass of Ni hyperaccumulators may significantly affect their immediate niche only for short periods of time soon after leaf fall, but repeated application may create high Ni levels under and around hyperaccumulators.

[2003 clinical practice guideline: Standards, Options and Recommendations for pain assessment in adult and children with cancer (summary report)]. / Recommandations pour la pratique clinique: Standards, Options et Recommandations pour l'évaluation de la douleur chez l'adulte et l'enfant atteints d'un cancer (mise à jour)--rapport abrégé.

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.

Clinical study of chronic pain in hereditary myopathies.

In the field of neuromuscular diseases, pain and its management remain imperfectly understood and described. We study 68 unselected, consecutive adult patients attending a multidisciplinary consultation for hereditary myopathy. Forty-six (67%) were suffering from chronic pain. Pain was assessed with self report questionnaire and a standardized clinical evaluation. Mean duration of the pain was 7.2+/-8.9 years, and multiple body sites were involved in 91% of cases. Usual pain intensity (Visual Analogue Scale 0-100) was moderate (39.5+/-26.2). For 42 patients (91%) the principal cause of the pain was of muscular origin, with frequent features of myofascial pain syndromes (MPS, 50%) and fibromyalgia (FMS, 26%). Pain was the major complaint for 6.3% of the patients. Pain management was essentially based on physiotherapy. Only a minority of patients (38%) has an appropriate drug treatment. Common analgesics appeared to be very effective in these patients.

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the federation of French Cancer Centers (FNCLCC), the 20 French 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. 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 develop clinical practice guidelines for the use of opioid analgesics with the exception of oral morphine and for opioid rotation related to the treatment of nociceptive pain in adults with cancer according to the definitions of the Standards, Options and Recommendations project. METHODS: In 1996, a working group, set up by the FNCLCC published clinical practice guidelines for pain management in adult and paediatric patients with cancer: In the light of the evolution of knowledge, and practice these guidelines need to be updated The section on "médical analgesic treatments" in the document published in 1996 was examined by the working group to identify which questions should be updated. These questions and the relevant key words were used to develop a search strategy which was used to search Medline, and for particular questions, Embase, from January 1994 to March 1999, for relevant references, published in English or French. RESULTS: For this update, only a few randomised clinical trials were identified, and their conclusions were generally weak. Thus much of the information in this document is based on the World Health Organisation (WHO) guidelines and represents the "state of the art" on this subject in France and is supported by expert agreement. Some changes to the original SOR are presented, particularly for the prescription of new opioids and opioid rotation. The full text of this SOR is available on the FNCLCC web site (http ://www.fnclcc.fr).
