We investigated the efficacy of Qi therapy as a non-pharmacological treatment for various symptoms presented by Korean combat veterans of the Vietnam War with Agent Orange Sequelae. Nine subjects volunteered to receive 30 minutes of Qi therapy, twice per day for 7 days. There was marked improvement in 89% of the patients with impaired physical activity, 86% of those with psychological disorder, 78% of those with heavy drug use, and 67% of those with fatigue, indigestion and high blood glucose levels. This data suggests that Qi therapy combined with conventional treatment has positive effects in reducing and managing the pain, psychosomatic disorders, and substance abuse in patients with Agent Orange Sequelae. We cannot completely discount the possible influence of the placebo effect, and more objective, clinical measures are needed to study the long-term effects of Qi therapy.

The federal Drug Abuse Treatment Act 2000 (DATA) opened a window of opportunity for patients with the disease of addiction by providing increased access to options for treatment. Previously, only methadone maintenance, approved for use only through specially regulated clinics, was available to treat opioid addiction. DATA allows any physician choosing to take a short specialty training course and become certified to prescribe buprenorphine. Buprenorphine and buprenorphine/ naloxone (Subutex, Suboxone) can be prescribed by certified physicians in a traditional office setting to treat patients with opioid dependence. Clinical studies indicate buprenorphine maintenance is as effective as methadone maintenance in retaining patients in substance abuse treatment and reducing illicit opioid use. Sublingual buprenorphine is more effective than clonidine or clonidine/naltrexone in short-term opioid detoxification treatment. Buprenorphine provides an additional tool to treat opioid addiction and improve the quality of lives of these patients. More physicians are needed to treat patients with addiction. DATA facilitates this by removing existing barriers and increasing access to treatment.

The characteristics of patients currently abusing controlled-release (CR) oxycodone admitted for inpatient detoxification were ascertained from medical record review of 48 inpatients with CR oxycodone dependence. Patients were categorized according to the manner in which they initially received the drug: illicitly or by prescription for legitimate medical use. Fifteen of the 48 patients (31%) initially obtained a CR oxycodone prescription legitimately for a medical condition. While none of these 15 patients had a history of prior opioid misuse, they were more likely than illicit CR oxycodone users to report prior detoxifications (P<0.03) as well as a lower mean age of first alcohol use (legitimate=11.7 versus illicit=14.7, P<0.05) and first illicit drug use (legitimate=12.8 versus illicit=15.8, P<0.05). These findings suggest that a history of substance abuse is common among patients abusing CR oxycodone, including individuals for whom CR oxycodone was initially legitimately prescribed for pain.

Opioid analgesic tolerance is a pharmacological phenomenon that overtime diminishes the opioid analgesic effect. However, it remains unknown as to whether a previous opioid exposure would have a long-term influence on opioid tolerance upon subsequent opioid administration. Here, we show that the onset and degree of antinociceptive tolerance to a subsequent cycle of morphine exposure were substantially exacerbated in rats made tolerant to and then recovered from previous morphine administration, indicating a long-term influence from a previous morphine exposure on the development of morphine tolerance. Mechanistically, morphine exposure induced a cyclic AMP and protein kinase A-dependent upregulation of neuronal glucocorticoid receptors (GR) within the spinal cord dorsal horn, which was maintained after discontinuation of morphine administration and significantly enhanced upon a second cycle of morphine exposure. Prevention of the GR upregulation with GR antisense oligonucleotides as well as inhibition of GR activation with the GR antagonist RU38486 effectively prevented the exacerbated morphine tolerance after subsequent cycles of morphine exposure. The results indicate that a previous morphine exposure could induce lasting cellular changes mediated through neuronal GR and influence morphine analgesia upon a subsequent exposure. These findings may have significant implications in clinical opioid therapy and substance abuse.

The non-medical use of OxyContin (controlled release oxycodone HCl) Tablets has been widely cited in media reports often leaving the impression that OxyContin was a source of primary or new onset drug abuse. However, no published research to date has examined the drug use history of those reporting non-medical use of OxyContin. This study examined rates of non-medical OxyContin use in the United States and the demographic and drug use profiles of those reporting such use, based on data from the 1999, 2000, and 2001 Substance Abuse and Mental Health Services Administration National Household Survey on Drug Abuse. Reported lifetime non-medical OxyContin use in the United States increased from 0.1% to 0.2% to 0.4% in 1999, 2000, and 2001 suggesting new incidence of 0.1%-0.2% per year. Compared to those reporting non-medical use of prescription analgesics other than OxyContin, non-medical OxyContin users were more likely to show a pattern of more serious drug abuse: they used multiple drugs, used needles for drug injection, and had higher rates of abuse and dependence. Approximately 83% of non-medical OxyContin users reported having used illicit drugs or other prescription medications non-medically prior to their first non-medical use of prescription analgesics. Even compared to those who reported non-medical use of other prescription analgesics, non-medical OxyContin users already had a more significant pattern of drug abuse before they began using prescription analgesics for non-medical purposes, suggesting that non-medical use of OxyContin is rarely the initiating factor leading to the abuse of other drugs.

The relationships between HIV-related pain, psychiatric disorders, and suicidal ideation (SI) are not well understood. The presented research investigated the ability of pain, psychiatric diagnoses, coping styles, and locus of control (LOC) to predict SI in 75 HIV-positive persons, using a sequential logistic regression. Reported psychiatric diagnoses included depression, anxiety, and substance abuse disorders. Variance accounted for by these analyses was approximated at 33%, with pain severity independently predicting SI after accounting for psychiatric diagnoses. Coping and LOC did not add significantly to the models. Given the prevalence of pain in this population, these results underscore the importance of assessing and treating pain and SI in persons with HIV.

Observations by health-care professionals suggest that the use of anabolic androgenic steroids (AAS) may be associated with lethal complications, but this has not yet been confirmed by controlled epidemiological studies. Here, we investigated the diagnoses (in the Swedish patient care records) and mortality rate among patients who tested positively for the presence of AAS (n = 248) in connection with receiving medical care. Patients who had tested negatively (n = 1215) were used for comparison. The proportions of patients who had received institutionalized care for substance abuse, psychiatric disorder or central thoracic pain were significantly higher in the AAS-positive subjects (RR = 2.2, 95% CI = 1.2-4.2; RR = 2.1, 95% CI = 1.4-3.2 and RR = 3.5, 95% CI = 1.1-10.9, respectively). Furthermore, unspecified convulsions were highly over-represented in the AAS-positive group (RR = 53.9, 95% CI = 7.0-415.7) and one of these patients died during a seizure. The standardized mortality ratios (SMR) in the AAS-positive patients and -negative patients were 20.43 (95% CI = 10.56-35.70) and 6.02 (95% CI = 3.77-9.12), respectively. The relatively higher SMR in the AAS-positive patients was observed irrespective of what type clinic had referred the patients for AAS testing. In conclusion, use of AAS appears to be an indicator of increased risk for premature death in several categories of patients. However, the nature of the association between AAS and premature death remains unclear and additional research on this question is urgently required.

Opioids are valuable analgesics, capable of providing pain relief and functional improvement not only in patients with cancer-related pain, but also in chronic noncancer-related pain patients. However, recent data have shown that the increasing prescription of opioids is associated with a rise in aberrant drug-related behaviour. The causes of this behaviour are multifactorial. Some pharmacotherapeutic, but in particular psychosocial risk and etiologic pain factors have been identified. The indication for the prescription of opioids must be very carefully weighed in the presence of any risk factors. In these cases the integration into a multimodal, interdisciplinary therapy programme is mandatory. A contractual agreement on the opioid therapy including goals, side effects, controls including urine drug testing and criteria to finish the opioid therapy are advisable. Assessment of the progress of therapy is based on the following factors: analgesic efficacy, adverse side effects, functional status and aberrant drug-related behaviour. In the absence of a successful opioid therapy, the treatment must be discontinued to avoid iatrogenic damage, substance abuse and illegal diversion. After discontinuation of the therapy, a comprehensive interdisciplinary re-evaluation is required.

Lewis and Fischer 344 (F344) rats differ in their pharmacological responses to a variety of drugs such as opioids, which has been partially attributed to differences in the endogenous opioid tone. Since opioid and alpha2-adrenergic mechanisms closely interact in nociception and substance abuse, a comparative study of the endogenous alpha2-adrenergic system in both inbred strains is of interest. Alpha-2 adrenoceptor subtypes and tyrosine hydroxylase, the rate-limiting enzyme of the catecholamine biosynthesis, were studied by Taqman RT-PCR analysis of gene expression in four brain areas of F344 and Lewis rats: hypothalamus, hippocampus, striatum and cortex. No differences were found in the mRNA levels of alpha2A- and alpha2C-adrenoceptors in any of the areas examined, however F344 rats exhibited lower levels of alpha2B-adrenoceptor transcripts in the hippocampus and higher levels in the hypothalamus. Tyrosine hydroxylase gene expression was found to be higher in hippocampus and striatum of F344 rats compared to Lewis, and a consistent 2-fold increase of the protein levels was detected by Western blots only in the case of the hippocampus. These results together with previous studies strongly suggest that the hippocampal noradrenergic activity of Lewis and F344 rats could be involved in their different responses to pain, stress and drug addiction.

The adequate cotreatment of chronic pain and addiction disorders is a complex and challenging problem for health care professionals. There is great potential for cannabinoids in the treatment of pain; however, the increasing prevalence of recreational cannabis use has led to a considerable increase in the number of people seeking treatment for cannabis use disorders. Evidence that cannabis abuse liability is higher than previously thought suggests that individuals with a history of substance abuse may be at an increased risk after taking cannabinoids, even for medicinal purposes. Smoked cannabis is significantly more reinforcing than other cannabinoid administration methods. In addition, it is clear that the smoked route of cannabis delivery is associated with a number of adverse health consequences. Thus, there is a need for pharmaceutical-grade products of known purity and concentration using delivery systems optimized for safety. Another factor that needs to be considered when assessing the practicality of prescribing medicinal cannabinoids is the difficulty in differentiating illicit from prescribed cannabinoids in urine drug testing. Overall, a thorough assessment of the risk/benefit profile of cannabinoids as they relate to a patient's substance abuse history is suggested.
