Cancer pain patients do not successfully handle opioids.

OBJECTIVE: To evaluate patterns of opioid handling as well as their associated -variables. DESIGN: A transversal study. SETTING: Institutional care. PARTICIPANTS: One hundred cancer pain patients aged 18 and above at diagnosis. INTERVENTIONS: Open and dichotomous questions related to opioid handling and a depression-anxiety scale. MAIN OUTCOME MEASURE(S): The percentage of patients who properly handled opioids. RESULTS: Of those surveyed, 42.1 percent of patients reported receiving opioid storage instructions, 73 percent did not receive any instructions related to proper opioid return/disposal, and 39 percent wrongly discarded them. The mean of patients with anxiety symptoms was 6.95 and of depression symptoms was 8.19. The Hebrew Version of the Hospital and Anxiety Scale total mean was 15.1. A significant relationship among patients with poor disposal habits was also found. CONCLUSIONS: Despite being aware of opioid's danger, patients' attitudes evidenced a poor safety responsibility. We believe that this might be due to the high percentage of disinformation and the influence of psychological symptoms on patients' decision-making.

The effects of TENS, interferential stimulation, and combined interferential stimulation and pulsed ultrasound on patients with disc herniation-induced radicular pain.

BACKGROUND: Electrotherapy is part of a physician's toolbox for treating various musculoskeletal conditions, including radicular pain, but the preferred modality is yet unclear. OBJECTIVE: To compare the short-term efficacy of three electrotherapeutic modalities in relieving lumbar disc herniation (LDH)-induced radicular pain. METHODS: Fourteen patients with LDH-induced radicular pain attended a single session of electrotherapy, which included four 10-min consecutive treatments: transcutaneous electrical nerve stimulation (TENS), interferential (IF) stimulation, a combined treatment with pulsed ultrasound and IF current (CTPI), and a sham control. Treatments were randomized and the straight leg raise (SLR) degree was measured immediately before and after each treatment. RESULTS: Each of the three active modalities significantly improved the SLR score. The most prominent improvement was observed in the CTPI condition, followed by IF and, finally, TENS. The sham stimulation did not affect the SLR scores. CONCLUSIONS: A single session with either TENS, IF current or CTPI is sufficient to improve the range of motion and degree of radicular pain associated with LDH. CTPI appears to be the most effective modality of the three, possibly due to greater penetration efficiency of the induced current. The effects of a long-term treatment schedule are yet to be identified.

Attitudes Toward the Use of Medical Cannabis and the Perceived Efficacy, Side-effects and Risks: A Survey of Patients, Nurses and Physicians.

Gaps between physician and patient perceptions may lead to misunderstandings and mismanage of treatment. There are sparse data about the differences in opinions toward medical cannabis (MC) between patients and health professionals. The aim of this study was to examine the attitudes toward MC, its perceived efficacy, side effects and risk of dependency, among patients, nurses and physicians. A cross-sectional study of samples of 430 patients, 65 nurses and 65 physicians in two large medical centers in Israel. Questionnaires were administered on attitudes, perceived efficacy, side-effects and perceived risks of dependency. Compared with nurses and physicians, patients who were using MC had the most positive attitudes toward MC (p < .001). Younger age, high school education, being Jewish and ever using MC, were associated with more positive attitudes toward MC among patients (p < .001). Among nurses and physicians, having an oncology specialty predicted more positive attitudes toward MC. Physicians had a less positive attitude toward MC compared to nurses (p < .01). Our study provides evidence that physicians are less positive in their views toward MC compared to nurses and patients. More information and awareness to MC may reduce the gap in perceptions between physicians and patients.

Depression level, not pain severity, is associated with smoked medical marijuana dosage among chronic pain patients.

BACKGROUND: The use of medical marijuana (MM) for the treatment of chronic pain is rapidly growing in the United States and Europe; however there is concern regarding the specificity of its therapeutic effects and the motivation underlying its use. While research indicates that among chronic pain prescribed opioids, depression has been associated with increased opioid dosage (regardless of pain levels), the extent to which depression and pain each contribute to MM dose among chronic pain patients is yet unknown. METHODS: This cross-sectional study included 209 chronic pain patients prescribed smoked MM, in flower or other plant form, with no concurrent opioid treatment. Ordinal regression analyses were performed in order to explore the unique contribution of mean pain level (1-10 scale), depression severity (measured by the Patient Health Questionnaire (PHQ-9)) and anxiety severity (measured by the Generalized Anxiety Disorder scale (GAD-7)) to doses of MM, while taking into account additional sociodemographic and clinical factors. RESULTS: Individuals with mild depression and those with moderate to severe depression were at significantly increased odds for using higher doses of MM in grams per month(Adjusted Odds Ratio(AOR) = 2.06,95% Confidence Interval(CI) = 1.05-4.01, and AOR = 5.95,95% CI = 1.97-17.98, respectively) compared to those without depression. In addition, individuals with mild depression were at significantly increased odds for smoking more MM joints daily(AOR = 2.07, 95% CI = 1.01-4.23) compared to individuals without depression. Mean levels of pain or anxiety severity were not significantly associated with either dose measures. CONCLUSIONS: Depression and MM dose are highly correlated and should be concurrently addressed during chronic pain treatment.

Personal experience and attitudes of pain medicine specialists in Israel regarding the medical use of cannabis for chronic pain.

INTRODUCTION: The scientific study of the role of cannabis in pain medicine still lags far behind the growing use driven by public approval. Accumulated clinical experience is therefore an important source of knowledge. However, no study to date has targeted physicians who actually use cannabis in their daily practice. METHODS: Registered, active, board-certified pain specialists in Israel (n=79) were asked to complete a Web-based survey. The survey was developed using the Qualtrics Online Survey Software. Questions were formulated as multiple-choice questions, and these addressed three areas of interest: 1) doctors' personal experience; 2) the role of cannabis in pain medicine; and 3) cannabis medicalization and legalization. RESULTS: Sixty-four percent of all practicing pain specialists in Israel responded. Almost all prescribe cannabis. Among them, 63% find cannabis moderately to highly effective, 56% have encountered mild or no side effects, and only 5% perceive it as significantly harmful. Common indications are neuropathic pain (65%), oncological pain (50%), arthralgias (25%), and any intractable pain (29%). Leading contraindications are schizophrenia (76%), pregnancy/breastfeeding (65%), and age <18 years (59%). Only 12% rated cannabis as more hazardous than opiates. On a personal note, 45% prefer cannabis for themselves or a family member. Lastly, 54% would like to see cannabis legalized in Israel. CONCLUSION: In this survey, pain clinicians experienced in prescribing cannabis over prolonged periods view it as an effective and relatively safe treatment for chronic pain, based on their own experience. Their responses suggest a possible change of paradigm from using cannabis as the last resort.

Prevalence of fibromyalgia syndrome in patients referred to a tertiary pain clinic.

BACKGROUND: Fibromyalgia syndrome (FMS), the prototypical central pain augmentation syndrome, is characterized by widespread pain and tenderness. Although patients referred to tertiary care pain clinics are recognized as suffering from chronic pain, they are generally considered to have pain attributable to discrete peripheral, nociceptive, or neuropathic etiology.The purpose of the current study was to assess the prevalence of FMS among consecutive patients referred to a tertiary pain clinic and to evaluate the contribution of central pain to the clinical impact upon such patients. METHODS: Eighty-five consecutive patients (38 were male, and 47 were female) attending a pain clinic were assessed for the presence of FMS. The presence of FMS was determined according to the 1990 American College of Rheumatology (ACR) classification criteria. Quality of life and physical functioning were assessed, utilizing a structured questionnaire. RESULTS: The ACR criteria for the classification of FMS were fulfilled by 41.2% of patients. Patients fulfilling FMS criteria ranked significantly lower on all domains of the SF-36, including general health, physical functioning, role limitation due to physical and emotional problems, vitality, social functioning, bodily pain, and mental health. Composite physical and mental health scores were significantly lower among patients fulfilling ACR FMS criteria. Patients fulfilling the ACR criteria for FMS felt significantly more tenderness, based on the mean number of tender points and the mean tenderness threshold, when compared with patients not fulfilling the ACR FMS criteria. CONCLUSIONS: A significant proportion of patients referred to a tertiary pain clinic were found to fulfill the ACR criteria for classification of FMS and thus exhibit an important element of central pain. Central pain augmentation should be actively searched for and therapeutically addressed in the evaluation and management of all patients with chronic pain.
