The phenomenological features of 35 obsessive-compulsive disorder (OCD) patients with a lifetime history of tics were compared to 35 age- and sex-matched OCD patients without tics. Seven categories of obsessions and nine categories of compulsions were determined using the symptom checklist of the Yale-Brown Obsessive-Compulsive Scale (YBOCS). Discriminant function analysis revealed that, compared to their counterparts without tics, OCD patients with tics had more touching, tapping, rubbing, blinking and staring rituals, and fewer cleaning rituals, but did not differ on obsessions. These preliminary findings suggest that the types of compulsions present may help to discriminate between two putative subgroups of OCD, i.e. those with and without tics.

Coerced or involuntary treatment comprises an integral, often positive component of treatment for addictive disorders. By the same token, coercion in health care raises numerous ethical, clinical, legal, political, cultural, and philosophical issues. In order to apply coerced care effectively, health care professionals should appreciate the indications, methods, advantages, and liabilities associated with this important clinical modality. An expert panel, consisting of the Addiction Committee of the Group for the Advancement of Psychiatry, listed the issues to be considered by clinicians in considering coerced treatment. In undertaking this task, they searched the literature using Pubmed from 1985 to 2005 using the following search terms: addiction, alcohol, coercion, compulsory, involuntary, substance, and treatment. In addition, they utilized relevant literature from published reports. In the treatment of addictions, coercive techniques can be effective and may be warranted in some circumstances. Various dimensions of coercive treatment are reviewed, including interventions to initiate treatment; contingency contracting and urine testing in the context of psychotherapy; and pharmacological methods of coercion such as disulfiram, naltrexone, and the use of a cocaine vaccine. The philosophical, historical, and societal aspects of coerced treatment are considered.

Women showed equivalent responses to drug administration with the exception of perception of well-being, which was significantly increased for women. These findings may have implications for differential risk for acute and chronic toxicity in women.

Understanding the drug interactions between antiretrovirals and opioid therapies may decrease toxicities and enhance adherence with improved HIV outcomes in opioid-dependent individuals. The authors report the results of a clinical pharmacology study designed to determine whether significant pharmacokinetic and/or pharmacodynamic interactions occur between the non-nucleoside reverse transcriptase inhibitor, delavirdine (DLV), and either methadone or levo-alpha acetyl methadol (LAAM) (n = 40). DLV significantly decreased methadone clearance (p = .018) and increased the methadone elimination half-life (p < .001) with a resultant increase in AUC of 19% and C(min)of 29%. The combined effect of DLV on the total concentration of LAAM and its active metabolites, norLAAM and dinorLAAM, was to significantly increase AUC by 43% (p < .001), C(max) by 30% (p = .013), and C(min) by 59% (p = .004) while decreasing T(max) (p = .05). Cognitive deficits over the seven-day study period as measured by the Mini-Mental State Examination, opioid withdrawal symptoms as measured by the Objective Opioid Withdrawal Scale, or complaints of adverse symptoms were not observed. Methadone and LAAM did not affect DLV concentrations. The findings from this study show that DLV treatment in methadone- or LAAM-maintained individuals results in altered opioid pharmacokinetics with an increased exposure and potential risk for opioid toxicity with methadone or LAAM treatment and an increased risk of cardiac toxicity with concomitant LAAM and DLV administration.
