Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of weight change during treatment with olanzapine or aripiprazole: results from a randomized, double-blind study.
Weight gain is a side effect of therapy with many atypical antipsychotics and may have important clinical repercussions with respect to long-term health and treatment compliance. The primary objective of this double-blind study was to compare the safety and tolerability of aripiprazole and olanzapine in patients with schizophrenia as evidenced by the percentage of patients exhibiting significant weight gain. ⋯ Olanzapine had a greater impact on patients' weight than aripiprazole. Significant differences in favor of aripiprazole were also observed in the effects of therapy on plasma lipid profile. Both treatment groups achieved comparable clinically meaningful improvements on efficacy measures. The observed effects on weight and lipids indicate a potentially lower metabolic and cardiovascular risk in patients treated with aripiprazole compared with those treated with olanzapine.

Antipsychotics are widely used in geriatric psychiatric disorders. A growing number of atypical antipsychotics are available, expanding clinical options but complicating decision-making. Many questions about use of antipsychotics in older patients remain unanswered by available clinical literature. We therefore surveyed expert opinion on antipsychotic use in older patients (65 years of age or older) for recommendations concerning indications for antipsychotics, choice of antipsychotics for different conditions (e.g., delirium, dementia, schizophrenia, delusional disorder, psychotic mood disorders) and for patients with comorbid conditions or history of side effects, dosing strategies, duration of treatment, and medication combinations. ⋯ The experts reached a high level of consensus on many of the key treatment questions. Within the limits of expert opinion and with the expectation that future research data will take precedence, these guidelines provide direction for common clinical dilemmas in the use of antipsychotics in elderly patients. Clinicians should keep in mind that no guidelines can address the complexities of an individual patient and that sound clinical judgment based on clinical experience should be used in applying these recommendations.

Randomized Controlled Trial Multicenter Study Clinical Trial
A placebo-controlled trial of bupropion SR as an antidote for selective serotonin reuptake inhibitor-induced sexual dysfunction.
This study reports the results of a placebo-controlled, double-blind comparison of bupropion sustained release (SR) as an antidote for sexual dysfunction versus placebo in 42 patients with selective serotonin reuptake inhibitor (SSRI)-induced sexual dysfunction. Exploratory analyses of the association of testosterone and sexual functioning in women in the study were also performed. ⋯ Bupropion SR, as an effective antidote to SSRI-induced sexual dysfunction, produced an increase in desire to engage in sexual activity and frequency of engaging in sexual activity compared with placebo. A larger study is needed to further investigate this finding.

Cognitive-behavioral therapy (CBT) can be successfully used to treat generalized anxiety disorder (GAD), with or without the inclusion of anxiolytics. The treatment of GAD using cognitive-behavioral techniques involves cognitive restructuring, relaxation, worry exposure, behavior modification, and problem solving. This article will review the principles used in CBT for the treatment of GAD and will discuss recent modifications of CBTs and how they may be employed. The simultaneous use of CBT and antidepressants will also be reviewed.

Insomnia is a pervasive condition with various causes, manifestations, and health consequences. Regardless of the initial cause or event that precipitates insomnia, it is perpetuated into a chronic condition through learned behaviors and cognitions that foster sleeplessness. This article reviews the rationale and objectives of cognitive-behavioral therapy (CBT), a safe and effective treatment for insomnia that may be used to augment hypnotic drugs or as a monotherapy. ⋯ The evidence supporting this behavioral approach shows that CBT is effective for 70% to 80% of patients and that it can significantly reduce several measures of insomnia, including sleep-onset latency and wake-after-sleep onset. Aside from the clinically measurable changes, this therapy system enables many patients to regain a feeling of control over their sleep, thereby reducing the emotional distress that sleep disturbances cause. Some clinical and practical issues that often arise when implementing this therapeutic approach for insomnia are also discussed.
