Review Comparative StudyAntimicrobial-induced mania (antibiomania): a review of spontaneous reports.
The authors reviewed reported cases of antibiotic-induced manic episodes by means of a MEDLINE and PsychLit search for reports of antibiotic-induced mania. Unpublished reports were requested from the World Health Organization (WHO) and the Food and Drug Administration (FDA). Twenty-one reports of antimicrobial-induced mania were found in the literature. ⋯ Although this is not a statistically significant risk, physicians must be aware of the effect and reversibility. Further research clearly is required to determine the incidence of antimicrobial-induced mania, the relative risk factors of developing an antimicrobial-induced manic episode among various demographic populations, and the incidence of patients who continue to have persistent affective disorders once the initial episode, which occurs while the patient is taking antibiotics, subsides. The authors elected to name this syndrome "antibiomania."

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA double-blind, randomized, prospective evaluation of the efficacy and safety of risperidone versus haloperidol in the treatment of schizoaffective disorder.
The relative efficacy and safety of risperidone versus haloperidol in the treatment of schizoaffective disorder was studied. Sixty-two patients (29 depressed type; 33 bipolar type) entered a three-site, randomized, double-blind, 6-week trial of risperidone (up to 10 mg/day) or haloperidol (up to 20 mg/day). Trained raters assessed baseline, weekly, and end-of-study levels of psychopathology with the Positive and Negative Syndrome Scale (PANSS), the 24-item Hamilton Rating Scale for Depression (HAM-D-24) and the Clinician-Administered Rating Scale for Mania (CARS-M). ⋯ There was no difference between risperidone and haloperidol in reducing both psychotic and manic symptoms in this group of patients with schizoaffective disorder. Risperidone did not demonstrate a propensity to precipitate mania and was better tolerated than haloperidol. In those subjects with higher baseline HAM-D scores (i.e., >20), risperidone produced a greater improvement in depressive symptoms than haloperidol.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA double-blind, randomized comparison of the efficacy and safety of intramuscular injections of olanzapine, lorazepam, or placebo in treating acutely agitated patients diagnosed with bipolar mania.
There are no rapid-acting intramuscular formulations of atypical antipsychotics available for quickly calming an agitated patient with bipolar disorder. In this study, 201 agitated patients with bipolar mania were randomly assigned to receive one to three injections of the atypical antipsychotic olanzapine (10 mg, first two injections; 5 mg, third injection), the benzodiazepine lorazepam (2 mg, first two injections; 1 mg, third injection), or placebo (placebo, first two injections; olanzapine, 10 mg, third injection) within a 24-hour period. Agitation was measured at baseline, every 30 minutes for the first 2 hours, and at 24 hours after the first injection using the Positive and Negative Syndrome Scale-Excited Component subscale and two additional agitation scales. ⋯ At 24 hours after the first injection, olanzapine remained statistically superior to placebo in reducing agitation in patients with acute mania, whereas patients treated with lorazepam were not significantly different from those treated with placebo or olanzapine. Furthermore, no significant differences among the three treatment groups were observed in safety measures, including treatment-emergent extrapyramidal symptoms, the incidence of acute dystonia, or QTc interval changes. These findings suggest that intramuscular olanzapine is a safe and effective treatment for reducing acute agitation in patients with bipolar mania.

Randomized Controlled Trial Clinical TrialComparing guanfacine and dextroamphetamine for the treatment of adult attention-deficit/hyperactivity disorder.
The objective of this study was to compare the efficacy of the alpha-2a agonist guanfacine with that of dextroamphetamine for the treatment of adult attention-deficit/hyperactivity disorder (ADHD). Seventeen adult outpatients who met DSM-IV criteria for ADHD participated in a double-blind, placebo-controlled, crossover study comparing drug effects on ADHD symptoms. Measures of change included the DSM-IV ADHD Behavior Checklist for Adults and the Copeland Symptom Checklist for Adult Attention Deficit Disorders. ⋯ The average dose of guanfacine was 1.10 (SD = 0.60), and the most common side effect of guanfacine was fatigue. No subjects discontinued drug trials. This preliminary study indicates that guanfacine may be a well-tolerated treatment option for adult ADHD.
