The Use of Cannabis as a Predictor of Early Onset of Bipolar Disorder and Suicide Attempts.

Introduction. Bipolar disorder (BD) implies risk of suicide. The age at onset (AAO) of BD carries prognostic significance. Substance abuse may precede the onset of BD and cannabis is the most common illicit drug used. The main goal of this study is to review the association of cannabis use as a risk factor for early onset of BD and for suicide attempts. Materials and Methods. PubMed database was searched for articles using key words "bipolar disorder," "suicide attempts," "cannabis," "marijuana," "early age at onset," and "early onset." Results. The following percentages in bipolar patients were found: suicide attempts 3.6-42%; suicide attempts and substance use 5-60%; suicide attempts and cannabis use 15-42%. An early AAO was associated with cannabis misuse. The mean age of the first manic episode in individuals with and without BD and cannabis use disorder (CUD) was 19.5 and 25.1 years, respectively. The first depressive episode was at 18.5 and 24.4 years, respectively. Individuals misusing cannabis showed increased risk of suicide. Discussion. Cannabis use is associated with increased risk of suicide attempts and with early AAO. However, the effect of cannabis at the AAO and suicide attempts is not clear.

Hyperthyroid rage: when bipolar disorder hides the real disorder.

Long-term lithium therapy has been associated with euthyroid goiter, hypothyroidism, and less commonly, hyperthyroidism. We report a case of a 19-year-old male patient with schizoaffective disorder who was hospitalized after trying to suffocate his mother. Severe psychomotor agitation persisted despite the high dose of antipsychotics. Initial laboratory tests showed elevated creatine kinase and free thyroxine. Lithium was replaced by sodium valproate, and new laboratory tests were obtained. After lithium discontinuation, the patient had a rapid improvement in agitation and tremors. Antithyroid drugs were not necessary, suggesting the diagnosis of lithium-associated thyrotoxicosis that progressed to spontaneous remission. There are only 2 other reports of lithium-associated thyrotoxicosis successfully treated with lithium withdrawal. Even patients on long-term use of lithium are not free from having acute thyroid dysfunction and may present with treatment-resistant symptoms.

Prevalence of bipolar disorder in a HIV-infected outpatient population.

This study assesses the prevalence of bipolar disorder (BD) among 196 HIV-infected adult outpatients attending in a specialized unit in Fortaleza, Brazil. Patients were interviewed with the Mood Disorder Questionnaire (MDQ), the Mini International Neuropsychiatric Interview (MINI), the Alcohol Use Disorders Identification Test (AUDIT), and a socio-demographic questionnaire based on WHO's behavioral surveillance surveys. Positive MDQ screening was found in 13.2% (N=26) and the BD diagnosis was confirmed in 8.1% (N=16) of the sample. There is an almost four times higher prevalence of BD among the HIV-infected patients of the sample (8.1%) than in the general population from the USA (2.1%). The prevalence of BD type I in the HIV patients was 5.6% (N=11) which is almost six times higher than the US general population (1%). The odds ratios of sexual behaviors and substance abuse variables correlated with BD were calculated. The variables associated with the diagnoses of BD were sex with commercial partners, sex outside the primary relationship, alcohol use disorders, and illicit drug abuse. The most common psychiatric comorbidity in the BD group was substance abuse (61.5%). A better understanding of psychiatric comorbidities and behavioral aspects of HIV-positive patients may help in improving long-term outcome of these patients.

Aripiprazole for patients with schizophrenia and schizoaffective disorder: an open-label, randomized, study versus haloperidol.

INTRODUCTION: Aripiprazole, a dopamine D2 receptor partial agonist, has also partial agonist activity at serotonin (5-HT)1A receptors and antagonist activity at 5-HT2A receptors. METHODS: In this 8-week, multicenter, randomized, parallel-group, open-label, flexible-dose study, patients diagnosed with schizophrenia or schizoaffective disorder were randomized to aripiprazole 15-30 mg/day or haloperidol 10-15 mg/day. RESULTS: Patients treated with both aripiprazole and haloperidol improved from baseline in Positive and Negative Syndrome Scale total, positive, and negative scores as well as in Clinical Global Impressions scores (all P<.001). At the end of the study, the percentage of patients classified as responders--according to >or=40% reduction in the Positive and Negative Syndrome Scale negative subscale score--was significantly higher in the aripiprazole group (20%) than in the haloperidol group (0%) (P<.05). Additionally, a higher number of patients receiving haloperidol required more anticholinergic medications (P<.001) than aripiprazole-treated patients, whereas more aripiprazole (45.5%) than haloperidol-treated patients (12.9%) required benzodiazepines (P=.002). At endpoint, rates of preference of medication were higher in the aripiprazole group (63.2%) than in the haloperidol group (21.7%), as expressed by patients and caregivers (P=.001). CONCLUSION: Aripiprazole and haloperidol had similar efficacy in terms of reduction of overall psychopathology. Although aripiprazole has been demonstrated to be superior concerning negative symptoms and in terms of tolerability (extrapyramidal symptoms) and preferred by patients and caregivers than haloperidol, significantly more aripiprazole-treated patients required benzodiazepines.

[Quality of life and depression in women abused by their partners]. / Qualidade de vida e depressão em mulheres vítimas de seus parceiros.

OBJECTIVE: To evaluate quality of life and depression among women who suffer domestic violence and to describe the socioeconomic profile of women who were abused by their partners and aspects of these abuses. METHODS: The study sample comprised 100 women who were abused by their partners and filed a complaint at the Police Office for Women of the state of Ceara, Brazil. Three questionnaires were applied: one for collecting demographic and violence data; the second one (GHQ-28) one to evaluate general quality of life; and the third one (Beck) to quantify depression. RESULTS: Abused women are young, married, Catholic, have children, low schooling and low family income. Alcohol use and jealousy were the main reported factors leading to partner's abuse. Of all, 84% of women suffered physical attacks. It was observed that 72% had depression symptoms; 78% had anxiety symptoms and insomnia; 39% had already thought of killing themselves, and 24% started taking anxiety medications after been abused. CONCLUSIONS: Data analysis suggests that domestic violence is associated with a negative perception by women of their mental heath.
