A victory for copyright owners: Kabushiki Kaisha Sony Computer Entertainment v Stevens

Casenote and comment on Kabushiki Kaisha Sony Computer Entertainment v Stevens in which the High Court found in favour of copyright owners - ruling that the definition of technological protection measures in s 10 of the Copyright Act includes not only those measures that physically prevent copying but also those measures that merely deter or discourage copying.

Resting energy expenditure is lower than predicted in people taking atypical antipsychotic medication

Resting energy expenditure (REE) is lower than predicted in persons taking atypical antipsychotic medication, and weight management is a significant clinical challenge for some of them. However, to date there have been no published guidelines to assist clinicians in choosing appropriate prediction equations to estimate energy expenditure in persons taking atypical antipsychotic medications. The objectives of this study were to measure REE in a group of men taking the atypical antipsychotic clozapine and to determine whether REE can be accurately predicted for this population using previously published regression equations. REE was measured using indirect calorimetry via a ventilated hood on eight men who had completed at least 6 months of treatment with clozapine. Comparisons between measured REE and predicted REE using five different equations were undertaken. The commonly-used Harris-Benedict and Schofield equations systematically overestimated REE. Predictions of REE from other equations were too variable for clinical use. When estimating energy requirements as part of a weight-management program in men who have been taking clozapine for 6 months, predictions of REE from the equations of Harris-Benedict and Schofield should be reduced by 280 kcal/day.

Atypical prostatic glandular proliferations on needle biopsy - Diagnostic implications, use of immunohistochemistry, and clinical significance

In recent times, PSA screening and a substantial increase in prostate needle biopsies have not only resulted in detection of minute foci of cancer but have also very likely resulted in increased detection of atypical glandular proliferations. Not uncommonly, there are only a limited number of atypical glands in these biopsies, and these require careful evaluation to enable an accurate diagnosis. We describe diagnostic implications, use of immunohistochemistry, and clinical significance of these lesions. Foci of atypical glands, also labeled atypical small acinar proliferation of uncertain significance, have features suspicious for but not diagnostic of cancer. Atypical foci include a broad group of lesions of differing clinical significance. These include benign, small acinar proliferations mimicking prostate cancer and atypical glandular proliferations suspicious for carcinoma. Definite diagnosis requires accurate histopathologic assessment and judicious use of immunohistochemistry. Patients with atypical glands on prostate needle biopsy have a high risk for harboring cancer and therefore have an increased risk for having cancer detected in subsequent biopsies.
