Patient and Context Factors in the Adoption of Active Surveillance for Low-Risk Prostate Cancer.

Importance: Although active surveillance for patients with low-risk prostate cancer (LRPC) has been recommended for years, its adoption at the population level is often limited.

Objective: To make active surveillance available for patients with LRPC using a research framework and to compare patient characteristics and clinical outcomes between those who receive active surveillance vs radical treatments at diagnosis.

Design, Setting, And Participants: This population-based, prospective cohort study was designed by a large multidisciplinary group of specialists and patients' representatives.

Comparison of dental and alveolar arch forms between different ethnic groups.

Objective: The aims of this study were to evaluate, by means of 3D software, any correlation between ethnic group and the shape and size of the dental arcade and its bony support, and to investigate the correspondence between the latter two variables within each ethnic group. The data gathered were also compared with the measurements of commercially available pre-formed archwires to determine which provide the best fit for each arch in each group.

Materials And Methods: The shape and size of the dental and alveolar arches of 29 subjects of African origin and 37 Caucasian subjects were compared in terms of linear inter-canine, inter-premolar and inter-molar measurements, overall arch length, and the distance between each tooth and the reference occlusal plane.

Laparoscopic microwave ablation and enucleation of small renal masses: preliminary experience.

Advancements in imaging and laparoscopy have led to the expansion of minimally invasive techniques in the ablation of small renal masses (SRMs). We report the results of a study aimed at assessing the efficacy of thermoablative microwave (MW) effects on SRMs and the haemostatic as well as necrotic MW effects on the parenchyma surrounding the neoplasm. From November 2008 to October 2010, 10 patients with SRMs underwent laparoscopy-guided Tru-Cut biopsy, MW tumour ablation, and enucleation.
