Abstract
This study aimed to quantify and compare the prevalence of simple prescribing errors made by clinicians in the first 24 hours of a general medical patient's hospital admission. Four public or private acute care hospitals across Australia and New Zealand each audited 200 patients' drug charts. Patient demographics, pharmacist review and pre-defined prescribing errors were recorded. At least one simple error was present on the medication charts of 672/715 patients, with a linear relationship between the number of medications prescribed and the number of errors (r = 0.571, p < 0.001). The four sites differed significantly in the prevalence of different types of simple prescribing errors. Pharmacists were more likely to review patients aged > or = 75 years (39.9% vs 26.0%; p < 0.001) and those with more than 10 drug prescriptions (39.4% vs 25.7%; p < 0.001). Patients reviewed by a pharmacist were less likely to have inadequate documentation of allergies (13.5% vs 29.4%, p < 0.001). Simple prescribing errors are common, although their nature differs from site to site. Clinical pharmacists target patients with the most complex health situations, and their involvement leads to improved documentation.

Abstract
OBJECTIVE To evaluate the performance of dermoscopists in diagnosing small pigmented skin lesions (diameter </= 6 mm) compared with an automatic multispectral computer-vision system. DESIGN Blinded comparison study. SETTING Dermatologic hospital-based clinics and private practice offices. Patients From a computerized skin imaging database of 990 small (</= 6-mm) pigmented skin lesions, all 49 melanomas from 49 patients were included in this study. Fifty randomly selected nonmelanomas from 46 patients served as a control. MAIN OUTCOME MEASURES Ten dermoscopists independently examined dermoscopic images of 99 pigmented skin lesions and decided whether they identified the lesions as melanoma and whether they would recommend biopsy to rule out melanoma. Diagnostic and biopsy sensitivity and specificity were computed and then compared with the results of the computer-vision system. RESULTS Dermoscopists were able to correctly identify small melanomas with an average diagnostic sensitivity of 39% and a specificity of 82% and recommended small melanomas for biopsy with a sensitivity of 71% and specificity of 49%, with only fair interobserver agreement (kappa = 0.31 for diagnosis and 0.34 for biopsy). In comparison, in recommending biopsy to rule out melanoma, the computer-vision system achieved 98% sensitivity and 44% specificity. CONCLUSIONS Differentiation of small melanomas from small benign pigmented lesions challenges even expert physicians. Computer-vision systems can facilitate early detection of small melanomas and may limit the number of biopsies to rule out melanoma performed on benign lesions.

Abstract
Speech warnings and communication systems are increasingly used in noisy, high workload environments. An important decision in the development of such systems is the choice of a male or a female speaker. There is little objective evidence to support this decision, although there are many misconceptions and misunderstandings on this topic. This paper suggests that both acoustic and non-acoustic differences (such as social attributions towards speakers of different sexes) between male and female speakers is negligible, therefore the choice of speaker should depend on the overlap of noise and speech spectra. Female voices do however appear to have an advantage in that they can portray a greater range of urgencies because of their usually higher pitch and pitch range. An experiment is reported showing that knowledge about the sex of a speaker has no effect on judgements of perceived urgency, with acoustic variables accounting for such differences.

Abstract
There is continued controversy as to the sequential steps and mechanism(s) responsible for the in vivo acquisition of multiple mutations during neoplastic transformation. We investigated the in vivo clonality and mutational spectra of hypoxanthine-guanine phosphoribosyltransferase (HPRT) mutations in T cells from children with acute lymphocytic leukemia (ALL) to gain insight into the mutagenic mechanisms associated with leukemogenesis. We observed several instances of multiple, independent HPRT mutations accumulating in vivo in T cell receptor (TCR) gene defined clones that had undergone extensive pre- and/or post-thymic expansion following chemotherapy. In addition, we also detected the accumulation of multiple unique single mutations within distinct expanding post-thymic T cell clones. This pattern of clonally restricted hypermutability is compatible with extensive cell proliferation and selection alone without postulating genomic instability. These observations provide a paradigm for a continuum of cellular events that eventually results in the clonal accumulation of mutations in selected populations of cells in vivo and may provide insight into the primary genetic events associated with leukemogenesis, as well as the development of second malignancies and drug resistance following chemotherapy.

Abstract
Tumor vascularity has been proposed as a prognostic indicator for a number of solid tumors. Although a correlation between microvessel number and metastatic behavior has also been suggested for cutaneous melanoma, the small number of cases studied to date allows one to draw only preliminary conclusions. In this study, we have assessed tumor vascularity in cutaneous melanoma by comparing 60 cases of metastasizing and non-metastasizing tumors matched for tumor thickness, age, sex, and anatomic site. Ulex europaeus agglutinin I appeared to be the most suitable vascular marker for this study. Our results indicate that there was no statistically significant difference between the two groups with regard to tumor vascularity. Even after identifying 15 cases of thin ( < 1.0 mm thick) melanoma, there was no significant difference in the number of microvessels between metastasizing and non-metastasizing tumors. Comparison of patterns of vascular microarchitecture also failed to discriminate between the two groups. Thus, our results indicate that tumor vascularity may not be an independent prognostic factor for cutaneous melanoma.

Abstract
Angiogenesis in malignant melanoma (MM) was evaluated by comparing mean vessel number (MVN) in Spitz's nevi (SN), thick and thin MMs that metastasized, and thick and thin MMs with > or = 10-year survival. Vessels were identified with antibodies against factor VIII-related antigen (FVIII) and CD34 in 37 MMs (17 < or = 1.9 mm and 20 > or = 4.0 mm) with > or = 10-year follow-up and 10 SN from children (< or = 9 years old). Fields (x250) with the highest vessel density were counted by independent observers blinded to clinical outcome. There were no differences in MVN between SN versus MMs (P = 1.0), but the distribution of vessels was much more uniform in SN. Seven MM pairs (> or = 5.5 mm) and five pairs (< or = 0.75 mm) were matched by sex, age, site, stage, and primary treatment (paired t-test). In the pairs > or = 5.5 mm, there was no correlation with MVN with either metastasis or death (FVIII P = 0.98; CD34 P = 0.85). Among the thin paired lesions, high MVN (FVIII = 46, CD34 = 39) was significantly related not only to metastasis (FVIII P = 0.04, CD34 P = 0.03) but also to death (FVIII P = 0.04, CD34 P = 0.05). MVN does not separate SN versus MM nor predict outcome in thick (> or = 4.0 mm) MMs; however, high MVN (> or = 42 average) is predictive of metastasis and death in MMs < or = 0.75 mm. Larger matched studies are indicated to confirm this observation.
