Cortical sulci and bipolar disorder.

The width of cortical sulci in bipolar patients (n=19) and healthy controls (n=35) was examined using a novel automated technique involving magnetic resonance imaging. All sulci were wider for bipolar patients than for healthy controls. Bipolar-control differences were largest for the superior and intermediate frontal sulci, smallest for the occipital and cingulate sulci, and intermediate in magnitude for the other sulci (intraparietal, inferior frontal, and central sulci). The results were interpreted in terms of neurodegenerative-illness-related processes, which could produce cortical atrophy and result in wider sulci.

A method for making estimates of the benefit of the late use of letrozole in patients completing 5 years of tamoxifen.

This article discusses the rationale for 2 methods of making estimates of the benefit of letrozole as extended adjuvant hormonal therapy after 5 years of tamoxifen. It uses information from the Overview metaanalyses to develop general rules for making estimates of remaining risk of relapse for women completing 5 years of adjuvant tamoxifen without relapse. The first derived method shows that the expected benefit for such a woman is approximately one tenth of her risk of relapse in years 0-10 if untreated. The second method uses a modification of Adjuvant!, a decision support tool, and makes similar estimates. The decision tool supplies needed estimates of initial risk and allows adjustment for competing mortality. Uncertainties involved in making these estimates are also discussed.

Accidental electrocution during autoeroticism: a shocking case.

A case of atypical autoerotic death is described. An 18-year-old white man clad in two brassieres was found dead in his bedroom by his brother. Two wet green terry cloths were under the brassiere cups, connected to the house current via two metal washers and a bifid electrical cord. Literature depicting nude women was found near the victim. Autopsy revealed second-degree and third-degree burns of the mammary regions. Death was attributed to accidental self-electrocution. The authors will discuss typical and atypical forms of autoerotic death.
