RESUMEN

Dopamine deficiency is found in both chronic cocaine abusers and Parkinson's disease. The authors sought to determine whether parkinsonian signs occur in chronic cocaine abusers. Fifty male patients with a history of chronic heavy cocaine abuse were examined on the Unified Parkinson Disease Scale (UPDS) and compared with 20 non-cocaine-abusing, age- and sex-matched control subjects. UPDS scores of cocaine abusers ranged from 0 to 1 (mean: 0.08 +/- 0.28) and, in control subjects, from 0 to 3 (mean: 0.15 +/- 0.49; P = 0.5; NS). This study suggests that chronic heavy cocaine abuse does not cause parkinsonism.

RESUMEN

Significant advances in our understanding the phenomenology of cocaine addiction have occurred in the past 12 years such that we now recognize addiction to cocaine as a major public health problem. We now can diagnose cocaine addiction more accurately. Furthermore, cocaine addiction has stimulated creation and testing of novel treatment efforts because standard addiction treatment, although efficacious, is not as effective for cocaine addiction as compared with other addictions. Much remains to be learned. We need to clarify symptoms and syndromes associated with cocaine addiction to more precisely delineate true "comorbidity." Special attention is needed to understand the course and response to treatment in women addicted to cocaine. Also, work is needed to clarify the interaction of HIV, cocaine, and pharmacotherapy used to treat HIV. Regarding treatment, effort is needed to better understand the interactions among educational, group, cognitive-behavioral, and pharmacologic interventions. Specific attention is needed regarding use of 12-step recovery programs adapted for cocaine addicts with comorbid psychiatric disorders, such as schizophrenia, mood, and anxiety disorders. Finally, we need to better understand ways of attracting and holding cocaine addicts in treatment earlier in the course of their disorder. To that end, "nontraditional" interventions, such as acupuncture, deserve systematic examination as alternative methods of recruitment and intervention for certain populations of cocaine addicts.

RESUMEN

We conducted a pilot study (N = 22) comparing the efficacy of desipramine and amantadine for treatment of cocaine dependence in methadone maintenance clients. The study which lasted 12 weeks, was double-blind, randomly assigned, and placebo-controlled. Subjects met DSM-III-R criteria for active cocaine dependence. All three groups' cocaine use, craving, and depressive symptoms declined significantly, but intergroup differences were not significant. Clients receiving desipramine were significantly more likely to remain in treatment and to be cocaine free at study completion. The results emphasize the importance of delivering comprehensive services to the cocaine user in methadone treatment. Further evaluations of these two medications as adjuncts in the treatment of cocaine dependence are needed.

RESUMEN

We present a case of tabes dorsalis, which consisted of intermittent, sharp pains and diffuse neurological abnormalities, and was initially considered to be a somatoform disorder. The unusual behavioural presentations of neurosyphilis may lead to premature psychiatric diagnoses. It is thus important that psychiatric consultants be aware of the myriad manifestations of the disease.

RESUMEN

We compared retention in treatment and psychological reactions during drug abuse treatment by 22 HIV-antibody positive, physically asymptomatic cocaine addicts to 22 matched HIV-seronegative cocaine addicts. All subjects participated in an outpatient clinical research project. There were no significant differences between groups in sociodemographics and psychiatric symptom scores on entrance or cocaine use except for route of administration (chi 2 = 11.59, df = 2, p less than .005). There were no significant differences among groups regarding being informed of serostatus and beginning treatment. There was a trend (p = .079) for more seropositives to complete treatment. Using end-point analysis to compare 11 seropositive subjects who completed a minimum of 2 weeks of treatment to a matched seronegative comparison groups, there were no significant differences in mood states except for "anger/hostility" (interaction of group x time; F = 2.24, df = 13/260, p less than .05). Informing drug abusers in treatment regarding positive HIV-serostatus was not associated with a lower treatment-retention rate or adverse psychological reactions when counseling regarding HIV issues was integrated with drug abuse treatment.

RESUMEN

We conducted a single-blind, random assignment, placebo-controlled, 12-week comparison of desipramine hydrochloride and amantadine hydrochloride as adjunctive treatments to counseling for cocaine dependence. Subjects were 54 outpatients who met DSM III-R criteria for active cocaine dependence and who completed a minimum of 2 weeks of treatment. Subjects treated with fixed doses of 200 mg/day desipramine (N = 17), 400 mg/day amantadine-placebo (N = 16), and placebo (N = 21) did not differ for lifetime cocaine use, lifetime histories of psychopathology, admission scores on psychometric assessments, and sociodemographics. All treatment groups demonstrated dramatic and persistent decreases in cocaine use, craving for cocaine, and psychiatric symptoms consequent to treatment. Although there was a trend for more dropouts by subjects taking desipramine, there were no significant differences among treatment groups regarding retention in treatment, craving for cocaine, and decreased cocaine use confirmed by urine toxicology. There was a trend for subjects treated with desipramine to maintain longer periods of cocaine abstinence. Mean plasma concentration of desipramine in a subsample of our subjects was less than that recommended for treatment of depression, thus the dosage of desipramine may have been subtherapeutic.

RESUMEN

Today health care providers are more likely to experience legal, moral and ethical dilemmas regarding their treatment principles given the climate of health care. Clinical practice in the United States is being affected by many external forces which can affect patient care. Government and insurance companies are attempting to legislate treatment as evidenced by DRG's and reimbursement patterns. Hospital and clinic administrators are pressuring faculty and staff to increase revenue by participating in more income generating activities. Within this milieu of dwindling resources, consumers continue to demand a variety of health care services. A case example of a woman who asked for a psychological intervention to treat a medical condition is presented. This case focuses on the important issue of offering efficacious treatments to informed patients with carefully diagnosed disorders. Whether scientific, ethically-based treatments are being rendered when any of the criteria, efficacious, informed and diagnosed are altered or missing, is open to doubt. This case is presented, not as a model of clinical management, but rather to stimulate discussion and generate ideas on how to better address future situations: (a) Where the patient requests an available treatment for a problem which would not be directly helped by such treatment; (b) how far must a clinician go to insure that informed consent has been reached?; (c) what is the physician's responsibility in providing what a patient wants in the way of treatment?; and (d) conversely, should clinicians provide medical interventions (at the patient's insistence) for psychological problems, for example, provide a penile prosthetic implant to a man whose disorder is clearly psychogenic impotence?

RESUMEN

We examined changes over 28 days in mood states, craving for cocaine, and sleep during short-term abstinence reported by 12 male, predominantly intravenous-using, cocaine-addicted subjects residing in a research facility. For comparison, we examined 10 nonaddicted control subjects. There were no significant differences between cocaine addicts and controls regarding demographics and selected DSM-III-R diagnoses other than psychoactive substance use disorder and antisocial personality disorder. There were significantly higher scores of psychiatric symptoms reported by cocaine addicts 1 week before admission. Mood-distress and depression scores recorded at admission and during short-term abstinence were significantly greater than those reported by controls. Addicts' mood-distress scores and craving for cocaine were greatest at admission and decreased gradually and steadily during the 28-day study. There were no significant differences between groups regarding reports of sleep other than difficulty falling asleep and clearheadedness on arising. Although there were significant differences in resting heart rate at admission and over time, there were no significant differences in weight gain or blood pressure. Given the absence of a classic "withdrawal" pattern, "short-term abstinence" may be a more appropriate classification of psychological and physical phenomena experienced by cocaine addicts who initiate abstinence in a controlled environment.

RESUMEN

Methadone maintenance was originally proposed as a long-term treatment modality for opiate addiction. However, most clients leave methadone maintenance rather than take methadone indefinitely and subsequently relapse to opiate use. In this article, the author examines relapse to opiate use by clients during and after methadone maintenance treatment in the United States. He reviews models of relapse prevention and aftercare which may be applicable to clients in methadone treatment. There now exist structured and psychotherapeutic relapse prevention methods which may be integrated into methadone maintenance treatment and could serve, in addition, to revitalize methadone maintenance treatment.

RESUMEN

We surveyed 11 methadone maintenance treatment programs in the Baltimore, Maryland, area to examine cocaine use among their 2414 clients and the methods employed to cope with that use. The percent of clients with at least one urine sample positive for cocaine during the month previous to study was 15.7% (379/2414) and ranged from 5.9% to 33.0% among the 11 programs. We determined the programs' use of monitoring strategies, treatment services, and administrative controls. We discuss the policy implications of our findings for methadone maintenance programs' efforts to address cocaine use with particular regard to the epidemic of human immunodeficiency virus (HIV) among intravenous drug users, their sexual partners, and offspring.
