[Cancer pain management--the palliative care approach].

Combining pharmacological pain management to other therapeutic options relieves most of cancer pain. The pharmacological approach lies on the WHO analgesic three steps. The first step (paracetamol, NSAIDs) is used for weak pain, and the second (weak opioids) for moderate pain. The third one, involving strong opioids, is indicated in moderate to severe pain. If morphine is still considered the first choice, other opioids can be useful in case of unacceptable side effects, inadequate antalgy, or renal failure. The use of co-analgesics can further optimize analgesia in certain cases. Their appropriate use must be carefully considered, regarding the side effects and the increased risk of drug interactions.

Psychopharmacology in supportive care of cancer: a review for the clinician. IV. Other psychotropic agents.

Besides benzodiazepine, antidepressant and neuroleptic agents, all of which have established roles in supportive care, other psychotropic drugs deserve consideration in selected conditions affecting patients with advanced cancer. This article briefly reviews relevant aspects of miscellaneous psychotropics available for secondline treatment, including nonbenzodiazepine sedative, hypnotic and anxiolytic drugs, anaesthetic agents, stimulants, and analgesic adjuvants acting on the central nervous system. The proper use of such subsidiary psychotropic agents requires that both their specificities and the particular characteristics of palliative care patients are taken into account.

Communication with terminal cancer patients in palliative care: are there differences between nurses and physicians?

The aim of this study was to find whether there were interprofessional differences in specific elements of communication with terminal cancer patients and decision-making processes that concern such patients. Given that interdisciplinary team work is one of the basic values in palliative care, if there are conflicting views between professions on such important issues it is most important to know about these and to understand them. A questionnaire utilized in an earlier survey of palliative care physicians and addressing their attitudes to and beliefs about specific elements of communication and decision making was sent to a sample of palliative care nurses working in the same regions, i.e. the French-speaking parts of Switzerland, Belgium and France. After a second mailing (reminder), 135 of the 163 questionnaires (83%) were returned. There was general agreement between nurses and physicians on questions dealing with perceptions of patients' knowledge of their diagnosis and stage of disease, patients' need for information, "do not resuscitate" orders and ethical principles in decision-making processes. Statistically significant, but small, differences between professional groups were only observed for a minority of the questions. Interprofessional differences in specific elements of communication with terminal cancer patients and decision-making processes affecting these patients were not so marked that they could be called "conflicting interprofessional views."

Clinical research in palliative care: choice of trial design.

Prospective controlled clinical trials provide the highest level of evidence in palliative care. Both parallel and crossover studies have unique advantages and disadvantages. Excellent knowledge of the patient population, interventions and endpoints are useful in choosing the most appropriate trial. Open pilot studies can assist the investigator in understanding the intervention and measurement tools better before embarking in costly and lengthy controlled trials. More controlled clinical trails are need to generate the evidence that will advance patient management in palliative care.

Psychopharmacology in supportive care of cancer: a review for the clinician. III. Antidepressants.

This review covers pharmacokinetics, adverse effects and drug interactions of antidepressants and the indications for them, with the aim of assisting the clinician working in palliative and supportive care in the prescription of such drugs. Practical considerations and decision trees to be used prior to the prescription of an antidepressant are also part of this review. Special emphasis is put on the management of depression, which is frequent in patients with advanced cancer and often remains underdetected and undertreated, or is treated at a stage when there is little time for medication to have an effect.

Psychopharmacology in supportive care of cancer: a review for the clinician: II. Neuroleptics.

Neuroleptics are frequently used in patients with advanced cancer. Most relevant and practical aspects of their use in supportive cancer care are reviewed, to assist the clinical oncologist and palliative care specialist when prescribing these drugs. This article reviews pharmacological properties, indications, such as delirium, nausea and vomiting, pain, anxiety and other symptoms, adverse effects, and drug interactions of neuroleptics and compares the profiles of different compounds. Special emphasis is put on the role of neuroleptics in the management of delirium.

Comprehensive assessment of patients in palliative care: a descriptive study utilizing the INTERMED.

Documentation in palliative care is often restricted to medical and sociodemographic information, and the assessment of physical and psychological symptoms or the quality of life. In order to overcome the lack of comprehensive information, we have evaluated the utility of the INTERMED-a biopsychosocial assessment method to document integrated information of patients' needs-in 82 consecutive patients for whom a palliative care consultation was requested. Results confirm the biopsychosocial heterogeneity of the sample, and the importance of integrated information to clinical, scientific, educational, and health care policy agendas. The INTERMED could become a useful method to tailor interdisciplinary interventions based on comprehensive patient needs assessment.

Attitudes and beliefs of palliative care physicians regarding communication with terminally ill cancer patients.

The subject of communication between palliative care physicians and their patients regarding their diagnosis and prognosis has not been extensively researched. The purpose of this survey was to compare the attitudes and beliefs of palliative care specialists regarding communication with the terminally ill in Europe, South America, and Canada. A sample of palliative care physicians from South America (Argentina and Brazil), French-speaking Europe, and Canada were identified, and posted a questionnaire. Physicians who stated that they practised palliative care at least 30% of their time were considered evaluable as palliative care specialists. Of a total of 272 questionnaires, 228 were returned (84%); and 182/228 (81%) respondents were considered to be palliative care specialists. Palliative care physicians in all three regions believed that cancer patients should be informed of their diagnosis and the terminal nature of their illness. Physicians reported that at least 60% of their patients knew their diagnosis and the terminal stage of their illness in 52% and 24% of cases in South America, and 69% and 38% of cases in Europe, respectively. All physicians agreed that 'do not resuscitate' orders should be present, and should be discussed with the patient in all cases. While 93% of Canadian physicians stated that at least 60% of their patients wanted to know about the terminal stage of their illness, only 18% of South American, and 26% of European physicians said this (P < 0.001). Similar results were found when the physicians were asked the percentage of families who want patients to know the terminal stage of their illness. However, almost all of the physicians agreed that if they had terminal cancer they would like to know. There was a significant association between patient based decision-making and female sex (P = 0.007), older age (P = 0.04), and physicians from Canada and South America (P < 0.001). Finally, in their daily decision making, South American physicians were significantly more likely to support beneficence and justice as compared with autonomy. Canadian physicians were more likely to support autonomy as compared with beneficence. In summary, our findings suggest that there are major regional differences in the attitudes and beliefs of physicians regarding communication at the end of life. More research is badly needed on the attitudes and beliefs of patients, families, and health care professionals in different regions of the world.

The effects of morphine on dyspnea and ventilatory function in elderly patients with advanced cancer: a randomized double-blind controlled trial.

BACKGROUND: Dyspnea represents a very frequent and distressing symptom in patients with advanced cancer. This study was undertaken to assess the efficacy of morphine on dyspnea and its safety for ventilatory function in elderly advanced cancer patients. PATIENTS AND METHODS: Nine elderly patients with dyspnea due to lung involvement were randomized to receive either morphine subcutaneously (5 mg in seven opioid-naïve patients and 3.75 mg in two patients on top of their regular oral dose of 7.5 mg q4 h) or placebo on day 1. On day 2, they were crossed over to receive the alternate treatment. Dyspnea was assessed every fifteen minutes using a visual analogue scale (VAS: 0-100 mm) and the ordinal scale developed by Borg (0-10 points). Pain, somnolence and anxiety were assessed using VAS. Respiratory effort, respiratory rate and oxygen saturation were also measured repeatedly. RESULTS: Mean changes in dyspnea 45 minutes after injection were -25 +/- 10 mm and -1.2 +/- 1.2 points for morphine, versus 0.6 +/- 7.7 mm (P < 0.01) and -0.1 +/- 0.3 points (P = 0.03) for placebo on VAS and Borg scale, respectively. No relevant changes were observed in somnolence, pain, anxiety, respiratory effort and rate, and oxygen saturation. CONCLUSIONS: Morphine appears effective for cancer dyspnea, and it does not compromise respiratory function at the dose level used.

Musculoskeletal and skin disorders in a population of floor-layers.

In the frame of a study on hydrocarbon-induced toxic effects, the knee morbidity and the prevalence of work-related arthralgias, gonalgias, myalgias and skin anomalies were investigated in a group a floor-layers. The results show that a previous history of knee morbidity is distinctly higher in floor-layers and that these workers have a higher prevalence of musculoskeletal and cutaneous disturbances than the comparison group. Owing to the fairly high prevalence of these troubles, it seems that this pathology deserves more attention and that more efficient preventive measures are indicated.

Hydrocarbon exposure, hypertension and kidney function tests.

Control and hydrocarbon exposed workers participated in a cross-sectional study about the nephrotoxicity of chronic hydrocarbon exposure. Different markers of glomerular and tubular function as well as the celluria were examined and compared. The results show that the interaction between hypertension and hydrocarbon exposure has an influence on the kidney function. For the clearance the interaction age-exposure seems to play a more important role than age or exposure alone. The most useful markers appear to be the albuminuria, the N-acetyl-beta-D-glucosaminidase activity, the retinol-binding-protein concentration and the creatinine clearance.
