Providing effective medical care to those with substance use disorders can be a challenge to clinicians. In this article, we briefly summarize issues that occur frequently in the medical treatment of substance users. The focus of this article is twofold. The first is to briefly summarize common co-occurring medical illnesses in those manifesting substance use disorders with an emphasis on issues related to providing effective treatment for these diseases in this population. Using specific examples of frequently occurring comorbid medical illness in substance users, including infectious diseases (hepatitis C and HIV disease), sexually transmitted diseases, and pregnancy as examples, the complexities of medical care for this population is demonstrated. Second, this article addresses some of the difficulties encountered in pharmacotherapy aimed specifically at treatment of substance use disorders. For example, difficulties in managing concomitant opiate therapy in those requiring medications for medical illness that may have strong and adverse interactions with opiates are addressed. Adverse events reported for some substance use disorder pharmacotherapies are also highlighted. We conclude with a brief review of models of care that have been effective in addressing the needs of this challenging population that can provide additional means for enhancing the clinical care of substance users. 相似文献

An increasing number of patients receiving radiation therapy have metallic implants such as hip prostheses. Therefore, beams are normally set up to avoid irradiation through the implant; however, this cannot always be accomplished. In such situations, knowledge of the accuracy of the used treatment planning system (TPS) is required. Two algorithms, the pencil beam (PB) and the collapsed cone (CC), are implemented in the studied TPS. Comparisons are made with Monte Carlo simulations for 6 and 18 MV. The studied materials are steel, CoCrMo, Orthinox, TiAlV and Ti. Monte Carlo simulated depth dose curves and dose profiles are compared to CC and PB calculated data. The CC algorithm shows overall a better agreement with Monte Carlo than the PB algorithm. Thus, it is recommended to use the CC algorithm to get the most accurate dose calculation both for the planning target volume and for tissues adjacent to the implants when beams are set up to pass through implants. 相似文献

The current opioid epidemic requires new approaches to increasing access to treatment for patients with opioid use disorders and to improve availability of medication assisted treatment. We propose a model where medical students complete the necessary training to be eligible for the waiver to prescribe opioid medications to treat these disorders by the time of medical school graduation. This plan would increase the number of Drug Abuse Treatment Act of 2000 (DATA 2000) waivered physicians who could gain additional experience in treating substance use disorders during residency and provide the access to clinical care needed for individuals suffering with opioid use disorder.

Self-report and physiological data from 27 male and 8 female cocaine-abusing volunteers exposed to cocaine (80 mg/70 kg p.o.) and placebo were examined for sex differences in their responses. Females reported significantly greater baseline ratings on the Pentobarbital-Chlorpromazine-Alcohol Group (PCAG) (sedation) and Lysergic Acid Diethylamide (LSD) (dysphoria) subscales of the Addiction Research Center Inventory-Short Form (ARCI) relative to males. In addition, females reported significantly greater ratings on the Visual Analogs Scales (VAS) Bad Drug Effects and Anxious/Nervous scales relative to males, regardless of drug. Cocaine produced greater increase in systolic blood pressure in males following cocaine, whereas females showed greater increases following placebo. These results suggest that a placebo control is necessary to determine sex differences in response to an active drug. 相似文献

We report results of a randomized, double-blind, placebo-controlled, within-subject study (n = 8) to determine the ability of cocaethylene to modulate acute responses to cocaine and identify significant pharmacokinetic interactions between cocaine and cocaethylene. Stable plasma cocaethylene concentrations (0, 50, or 200 ng/ml) were maintained for 840 minutes. Cocaine (0, 0.25, or 0.5 mg/kg) was injected over 1 minute after 240 minutes of cocaethylene. Blood samples, subjective, and physiological measures were collected. No differences over baseline responses were observed following 240 minutes of a steady state cocaethylene infusion for cardiovascular or subjective responses. "Rush" duration following a cocaine challenge (0.5 mg/kg) declined when administered during the course of a 200 ng/mL cocaethylene infusion. (p = 0.01). No pharmacokinetic interaction occurred when cocaine was administered in conjunction with cocaethylene. Findings indicate that continuous 8-hour exposure to cocaethylene is safe, produces acute tolerance to itself, and reduces some behavioral effects of coadministered cocaine. Agonist substitution therapy may have potential as an alternative treatment for cocaine dependence. 相似文献
