Do monthly or seasonal variations exist in suicides in a high-risk setting?

An unequal distribution of suicides over months and seasons has been a consistent finding in epidemiological surveys on suicide. Jails and prisons are a high-risk setting for suicide all over the world. The high prevalence of both outward and self-directed violence in prison populations indicates dysfunctional central serotonin (5-HT) neurotransmission and, therefore, could account for an unequal distribution of suicides over months and seasons due to underlying bioclimatic factors. Within a total survey of suicides in the Austrian penitentiary system, the weekly, monthly and seasonal distribution of custodial suicides between 1947 and 1999 was studied. After an explorative comparison of suicide distribution over weekdays, months and seasons of the year by chi2-tests, a harmonic Poisson regression model was performed to detect seasonality of suicides. No unequal distribution of suicides was evident over the 53-year period. A limitation of this study was its sample size of 412, a low number compared with population-based samples, where a spring suicide peak was consistently found. An explanation for lacking seasonality could be that bioclimatic factors are less relevant in urban, industrialized areas, where jails and prisons usually are located. One of the core characteristics of penal institutions is the limited possibility for communication and social interaction. This social isolation is independent of seasonal changes. If the individual's possibilities for social interactions are limited, the influence of seasonal changes in social activities may be less relevant. This could explain the absence of seasonal changes in custodial suicide incidence.

Early fluoxetine treatment of post-stroke depression--a three-month double-blind placebo-controlled study with an open-label long-term follow up.

OBJECTIVE: Poststroke depression is a frequent psychiatric complication after stroke that may have strong negative impact on rehabilitation therapy and functional recovery. This study was conducted to show the efficacy and safety of early treatment with the selective serotonin reuptake inhibitor fluoxetine in post-stroke depressed patients. METHODS: This double-blind, randomized placebo-controlled study was of patients within two weeks after stroke. Moderate to severe depressed patients (determined by Hamilton Depression Scale (HDS) > 15, the Beck Depression Inventory (BDI) and the Clinical Global Impression (CGI) Scale) were randomized to receive either 20 mg/d fluoxetine or placebo for 3 months. Beside the psychiatric assessment, patients were evaluated by use of the Scandinavian Stroke Scale (SSS), the Mini-Mental-State-Examination (MMSE) and the Barthel-Index (BI). An open-label long-term follow up was done 18 months after the initial assessment. RESULTS: 54 depressed patients of an inpatient population of 242 consecutive stroke patients aged 25 to 85 years entered the trial within the first two weeks post-stroke. 50 patients completed the trial per-protocol. The initial severity of depression was comparable in the two groups (mean baseline HDS score 32.8 in the fluoxetine vs. 30.3 in the placebo group), as were neurological symptom severity and demographic parameters. Significant improvement was seen in both groups within 4 weeks of treatment, whereas no advantages of fluoxetine could be observed at this time. This indicates a high degree of spontaneous recovery during early rehabilitation therapy. BDI scores of patients treated with fluoxetine further decreased until the follow-up at 12 weeks, whereas the scores increased again in the placebo group. This depressive relapse of the placebo patients after the end of most rehabilitation efforts was evident at a long-term follow-up 18 months after inclusion, when patients who had been treated with fluoxetine were significantly less depressed. No side effects of fluoxetine treatment were detected. CONCLUSIONS: The advantages of fluoxetine were obvious at the follow-up 18 months after inclusion, but could not be demonstrated within the first three months of controlled treatment. The multitude of therapeutic efforts that take place in the early phase of rehabilitation might have facilitated spontaneous recovery from depression and might have hindered benefits of antidepressant treatment to become obvious. Fluoxetine treatment was well tolerated and safe.

The relevance of suicidal behaviour in jail and prison suicides.

PURPOSE: Suicide rates in correctional institutions have been increasing during the last decades. There has been little interest in whether suicidal ideation and intent has been documented by non-medical prison staff (reports of attempted suicide, suicide threats, self-harm), and whether these signs of suicidality had the consequence of adequate intervention efforts. METHODS: The personal files of inmates who committed suicide in the 29 Austrian jails and prisons during the last 25 years (1975-1999) were included. We analysed personal characteristics, criminological data, circumstances of custody and information about psychiatric disorders and treatment. RESULTS: Of a total of 250 suicides, 220 personal files were available and included. Suicide attempts were known in 50% of all suicides and 37% had expressed suicidality. In >20%, non-medical staff had documented signs of suicidality, but no further preventive action (e.g. referral to psychiatric care) had taken place. CONCLUSION: Signs of suicidality play an important role in vulnerability profiles for jail and prison suicides and should have the minimal consequence of further psychiatric care.

Sexualization and lifestyle impulsivity: clinically valid discriminators in sexual offenders.

Following clinical observations in this study a comparison was undertaken between nonsexualized rapists, sexualized rapists, and pedophilic child molesters in terms of psychometric measures, criminological data, and DSM-IV diagnoses following the authors' hypotheses that nonsexualized and sexualized rapists differ in respect of psychiatric comorbidity and criminal history and sexualized rapists and pedophilic child molesters are more similar as regards to psychiatric comorbidity (anxiety, depression, and aggression) and criminal history variables than nonsexualized and sexualized rapists are. Preliminary findings confirmed the hypotheses: the authors found significant differences between paraphilic and sexualized sex offenders on one hand--regardless whether they had offended against minors or adults--and a group of sex offenders exhibiting a history of high lifestyle impulsivity on the other hand. From a psychiatric clinical point of view, paraphilic or sexualized rapists could be shown to resemble more the pedophilic child molesters. Therapeutic approaches should take these findings into account.
