RESUMO
Stuttering, a disturbance in the normal fluency and time patterning of speech is usually developmental. In some cases, it is acquired, and causes include stroke, brain tumor, and trauma. Implicated in the causation of stuttering are overactive presynaptic dopamine systems in the region of the brain that modulate verbalization. It is a rare side effect of antipsychotic medications and has been reported with phenothiazines, clozapine, and risperidone. This is a report of a patient who developed stuttering when treated first with chlorpromazine and later with risperidone. Patient had a diagnosis of schizoaffective disorder and had been treated with antipsychotic medications including haloperidol, olanzapine, and paliperidone. He developed stuttering for the first time upon receiving intramuscular injections of chlorpromazine for treatment of agitation. The stutter improved and eventually resolved. He subsequently presented with a severe stutter when he was treated with risperidone. The stutter improved after risperidone was discontinued. It is speculated that drug-induced stuttering may be a manifestation of akathisia leading to noradrenergic and serotonergic mechanisms being implicated. It could be that either the cholinergic, dopaminergic or serotonergic systems are involved or that there is an imbalance of these systems that may be relevant.

We have noticed an increase in the number of patients who go through the court-ordered evaluation (COE) process but are not placed on a court-ordered treatment, and who then return to the hospital on another COE petition within one year from their initial discharge. The aim of this study is to examine what factors might be involved in rehospitalization in this population of psychiatric patients. The records of 146 readmitted patients and 146 randomized patients not readmitted were compared for various risk factors. Data were analyzed using univariate and mutivariate procedures. All patients who had diagnoses of substance-induced mood or psychotic disorders were readmitted within one year. Other risk factors included younger age, seriously mentally ill (SMI) status, longer length of stay and having a psychotic or schizophrenia spectrum disorder. Substance-induced mood or psychotic disorder may play significant roles for patients who are rehospitalized within a year of initial COE.
RESUMO
BACKGROUND: Prescription drug monitoring programs (PDMPs) have been implemented as tools to help identify misuse of prescription medications. There has been mixed data regarding the efficacy of PDMP, and physician attitudes towards it vary. In an inpatient psychiatric hospital, history of substance use, including prescription medications, and results of urine drug screens (UDS) are obtained during the admission interview. OBJECTIVES: The aim was to determine if the substance use history and UDS are sufficient to identify substance use as compared to information obtained by Arizona's Controlled Substance Prescription Monitoring Program (CSPMP) in an inpatient setting. METHODS: A prospective chart review was completed on all newly admitted patients to the behavioral units within a 30-day period to identify those that had substance use disorder. CSPMP records were checked for all subjects for patterns of misuse. The test results were not normally distributed, so non-parametric tests were chosen for analyses. RESULTS: Of the 220 patients admitted, 127 patients had a substance use diagnosis. Out of the 127 patients, 67(30.5 %) were diagnosed with either opioid, benzodiazepine or amphetamine and stimulant use disorder. Of the 125 (56.8%) patients who had a substance use disorder, the substance abuse diagnosis had been made by the psychiatrist in the medical chart. CSPMP identified only 2 (0.8%) additional patients that were missed during the intake. CONCLUSIONS: The CSPMP provided little benefit to improving substance abuse detection when compared with the clinical interview and UDS results. This is attributed to the comprehensive evaluation done during the intake.

Antipsychotic-induced agranulocytosis is a significant side effect that is known to occur with most of the antipsychotic medications. It usually resolves once the medications are stopped and patients are able to be switched over to another antipsychotic medication. Lurasidone has not been reported to cause leukopenia and neutropenia. This case report is of a patient with a past history of risperidone induced-aganulocytosis developing dose related leukopenia and neutropenia with lurasidone.
RESUMO
Trauma exposure itself in the absence of posttraumatic stress disorder (PTSD) may be associated with hippocampal volume deficits. We meta-analytically compared hippocampal volumes in PTSD subjects, in trauma-exposed subjects without PTSD, and in trauma-unexposed subjects. Using the words and phrases PTSD, neuroimaging, hippocampus, brain, violence, trauma, abuse, rape, war, combat, accident, and disaster, we searched major computerized databases to obtain candidate studies through 2008 for inclusion. We identified 39 hippocampal volumetric studies in adults with PTSD compared to control groups consisting of either trauma-exposed controls without PTSD or trauma-unexposed controls, or both. We meta-analytically compared left, right, and total hippocampal volumes between 1) PTSD subjects and a trauma-unexposed group, 2) PTSD subjects and a trauma-exposed group without PTSD, and 3) a trauma-unexposed group and a trauma-exposed group without PTSD. Hippocampal volumes were smaller in the PTSD group and trauma-exposed group without PTSD compared to the trauma-unexposed group. Further, the right hippocampus was smaller in the PTSD group compared to the trauma-exposed group without PTSD. Additionally, the right hippocampus was larger than the left in the PTSD and trauma-unexposed groups but not in the trauma-exposed group without PTSD. Hippocampal volume reduction is associated with trauma exposure independent of PTSD diagnosis, albeit additional hippocampal reduction was found in PTSD compared to the trauma-exposed group without PTSD.

Priapism defined as persistent, painful and prolonged penile erection, was previously thought to be associated only with the use of the older, conventional first generation or typical antipsychotic medications as well as some other medications, notably, trazodone. The mechanism of priapism associated with antipsychotics is not clear but is thought to be related to alpha-adrenergic blockage that is mediated by the alpha receptors in the corpora cavernosa of the penis. Atypical antipsychotics, also known as second-generation antipsychotics, owing to their favorable side effect profile, are being prescribed with increasing frequency and are not as frequently considered to cause priapism. Some case reports reporting this side effect with their use, however, are found. Pubmed and Ovid databases were searched to obtain all articles and case reports of antipsychotic drug-induced priapism. Key search words included 'priapism', 'antipsychotics' and 'drug-induced priapism'. References of all identified studies were also reviewed. A total of 50 publications were obtained. Most of the atypical antipsychotics have been reported to cause priapism. These cases have occurred in patients shortly after having been started on the antipsychotic medications as well as in those who have been on them for an extended period of time without modification in dosage, and have also occurred sometimes, with the addition of another antipsychotic, lithium or serotonin-specific reuptake inhibitor. Priapism has been documented with nearly all the atypical antipsychotic medications. It is, however, a rarely reported side effect and therefore, underappreciated. Priapism can cause irreversible erectile dysfunction and is a urologic emergency. Clinicians should monitor patients on these medications for this rare, yet significant side effect. Furthermore, caution must be used when adding new drugs to the regimen and patients should be closely monitored for this side effect. Educating patients about the risk of developing priapism would help increase awareness of the side effect and promote early reporting thereby, decreasing long-term morbidity.

Posttraumatic stress disorder (PTSD) is associated with decreased hippocampal volume, but the relationship between trauma and brain morphology in the absence of PTSD is less clear. In this study, measures of brain integrity were determined by estimating gray and white matter regional brain volumes using structural magnetic resonance imaging in six patients with PTSD and in five controls with comparable trauma exposure but without clinical evidence of PTSD. The only statistically significant volume difference between groups was observed multivariately in the white matter of the right temporal lobe (superior temporal gyrus, fusiform gyrus, parahippocampal gyrus, white-matter stem, middle temporal gyrus, and inferior temporal gyrus), although small sample sizes limit the power to detect between-group differences. Both groups showed heterogeneity in cerebral atrophy.

OBJECTIVE: This pilot study was undertaken to exclude the effects of alcohol and other substances on brain morphology in posttraumatic stress disorder. BACKGROUND: Posttraumatic stress disorder and alcohol use are among the conditions associated with decreased hippocampal volume. The possible confounding contribution of alcohol and other substances of abuse to decreased hippocampal volume in posttraumatic stress disorder has not been previously explored directly. METHOD: In this pilot study, magnetic resonance imaging scans of 4 substance naive subjects with combat-related posttraumatic stress disorder and of 4 controls were quantified. RESULTS: Bilateral hippocampal volumes were significantly smaller in posttraumatic stress disorder subjects. No significant differences were found between posttraumatic stress disorder subjects and the comparison group for total brain, gray and white matter, and ventricular volumes. CONCLUSIONS: These findings suggest that posttraumatic stress disorder in the absence of alcohol and other substance abuse may be associated with reduced hippocampal volume. The significance of reduced hippocampal volume in posttraumatic stress disorder is discussed.
