The ethics of care and treatment of sex offenders

The ethics of care acknowledges the importance of establishing and maintaining practices that help people to meet their needs, develop and protect basic capabilities for problem solving, emotional functioning, and social interaction, and avoid pain and suffering. In this article, we explore the contribution an ethics of care perspective can make to work with sex offenders. First, we briefly describe five classes of ethical problems evident in work with sex offenders. Second, the concept of care is defined and a justification for a version of care theory provided. Third, we apply the care ethical theory to ethical issues with sex offenders and demonstrate its value in responding to the five classes of problems outlined earlier.

Oxidative pathways as a drug target for the treatment of autism

Importance of the field: Autism is a severe, pervasive developmental disorder, the aetiology of which is poorly understood. Current pharmacological treatment options for autism are often focused on addressing comorbid behavioural problems, rather than core features of the disorder. Investigation of a new treatment approach is needed.

Areas covered in this review: Recent research has indicated a possible role of abnormalities in oxidative homeostasis in the pathophysiology of autism, based on reports that a range of oxidative biomarkers are significantly altered in people with autism. This article reviews the current findings on oxidative stress in autism, including genetic links to oxidative pathways, changes in antioxidant levels and other oxidative stress markers. We conducted a search of the literature up to June 2010, using Medline, Pubmed, PsycINFO, CINAHL PLUS and BIOSIS Previews.

What the reader will gain: This review provides an overview of the current understanding of the role of oxidative stress in autism. This will assist in highlighting areas of future therapeutic targets and potential underlying pathophysiology of this disorder.

Take home message: Abnormalities in oxidative homeostasis may play a role in the pathophysiology of autism. Antioxidant treatment may form a potential therapeutic pathway for this complex disorder.

The safety of medications for the treatment of bipolar disorder during pregnancy and the peurperium

Risks associated with pharmacological treatment of bipolar disorder are heightened during reproductive events. Treatments need to be planned with the mutual agreement of both the treating physician and the patient and tailored to the needs of the individual so as to minimise risk while providing adequate treatment. Conventional treatments have all been associated with teratogeny in first trimester exposure, lithium with cardiac malformation and valproate and carbamazepine with neural tube malformations. There have been an insufficient number of first trimester exposures to the newer anticonvulsant mood stabilisers, lamotrigine and oxcarbazepine, to determine whether there is a safety advantage in switching to these agents. Increasingly, atypical antipsychotics are being suggested as useful agents for the treatment of bipolar disorder. While not known to be teratogenic, there are other reproductive safety concerns associated with these agents. Bipolar disorder patients may be prescribed antidepressants, and many of these agents are associated with a low safety risk during reproductive events, however data regarding use of these agents are currently equivocal. Adverse outcomes from inadequate pharmacological prophylaxis have been documented for both the mother and the baby. Risks and benefits need to be carefully balanced based on an accurate review of the evidence.

A pilot randomized, double-blind, placebo-controlled study of granisetron in the treatment of sexual dysfunction in women associated with antidepressant use

A pilot study was conducted to evaluate the usefulness of granisetron for the treatment of antidepressant induced sexual dysfunction in women. Twelve women with antidepressant induced sexual dysfunction (AISD) were assigned granisetron (n=5) or placebo (n=7) in a 14-day randomized, double-blind, placebo-controlled study. One participant in the granisetron group did not complete the study. Participants were assessed at baseline, day 7 and day 14 using the Feiger Sexual Function and Satisfaction Questionnaire and the Arizona Sexual Experience Scale. No statistical differences were measured at baseline or at endpoint between the granisetron or placebo group. This study did not produce evidence supporting the usefulness of granisetron in AISD.
