Structure and modules of computer informational-analytical system "Electronic atlas of Russia" is presented, the object of mapping in this system is epidemiology of socially significant infectious diseases. Systemic information on processes of emergence and spread of socially significant infectious diseases (anthroponoses, zoonoses and sapronoses) in the population of Russian Federation is presented in the atlas. Detailed electronic maps of country territory filled with prognosis-analytical information created by using technological achievements of mathematic and computer modeling of epidemics and outbreaks of viral and bacterial infections are of particular interest. Atlas allows to objectively evaluate the pattern of infection spread, prepare prognoses of epidemic and outbreak developments taking into account the implementation of control measures (vaccination, prophylaxis, diagnostics and therapy) and evaluate their economic effectiveness.

Quantitative analyses of brain structures from Magnetic Resonance (MR) image data are often performed using automatic segmentation algorithms. Many of these algorithms rely on templates and atlases in a common coordinate space. Most freely available brain atlases are generated from relatively young individuals and not always derived from well-defined cohort studies. In this paper, we introduce a publicly available multi-spectral template with corresponding tissue probability atlases and regional atlases, optimised to use in studies of ageing cohorts (mean age 75 ± 5 years). Furthermore, we provide validation data from a regional segmentation pipeline to assure the integrity of the dataset.

Delineation of target volumes and organs at risk in adjuvant radiotherapy of early breast cancer: national guidelines and contouring atlas by the Danish Breast Cancer Cooperative Group.
During the past decade planning of adjuvant radiotherapy (RT) of early breast cancer has changed from two-dimensional (2D) to 3D conformal techniques. In the planning computerised tomography (CT) scan both the targets for RT and the organs at risk (OARs) are visualised, enabling an increased focus on target dose coverage and homogeneity with only minimal dose to the OARs. To ensure uniform RT in the national prospective trials of the Danish Breast Cancer Cooperative Group (DBCG), a national consensus for the delineation of clinical target volumes (CTVs) and OARs was required.
A CT scan of a breast cancer patient after surgical breast conservation and axillary lymph node (LN) dissection was used for delineation. During multiple dummy-runs seven experienced radiation oncologists contoured all CTVs and OARs of interest in adjuvant breast RT. Two meetings were held in the DBCG Radiotherapy Committee to discuss the contouring and to approve a final consensus. The Dice similarity coefficient (DSC) was used to evaluate the delineation agreement before and after the consensus.
The consensus delineations of CTVs and OARs are available online and a table is presented with a contouring description of the individual volumes. The consensus provides recommendations for target delineation in a standard patient both in case of breast conservation or mastectomy. Before the consensus, the average value of the DSC was modest for most volumes, but high for the breast CTV and the heart. After the consensus, the DSC increased for all volumes.
The DBCG has provided the first national guidelines and a contouring atlas of CTVs and OARs definition for RT of early breast cancer. The DSC is a useful tool in quantifying the effect of the introduction of guidelines indicating improved inter-delineator agreement. This consensus will be used by the DBCG in our prospective trials.
Swedish anatomists Anders and Gustaf Retzius, father and son, collaborated with artists, photographers, and printers to produce image plates for their many publications in normal, comparative, morbid, and microscopic anatomy. This article explores the role of images in their oeuvres, identifying impacts of changing scientific ideals, aesthetic sensibilities, and technologies of observation and visualization. It examines how the Retziuses mobilized historically contingent concepts of truth and beauty to support claims to authority. Anders Retzius, influenced by post-Kantian philosophy, viewed truth and beauty as inherent in natural phenomena, independent of the researcher. Scientific authority rested on abilities to observe and convey the truth and beauty of examined specimens, preferably aided by a skilled artist. For Gustaf Retzius, epistemic authority depended on his expertise as scientist, publisher, and illustrator of his own works. Like Santiago Ramón y Cajal he favored an “anti-aesthetic” style, while at the same time publishing sumptuous image plates.

The Canadian Cardiovascular Outcomes Research Team's (CCORT) Canadian Cardiovascular Atlas project was developed to provide Canadians with a national report on the state of cardiovascular health and health services in Canada. Written by a group of Canada's leading experts in cardiovascular outcomes research, the CCORT cardiac Atlas will cover a wide variety of topics ranging from cardiac risk factors and cardiac mortality rates to the treatment of patients with acute myocardial infarction and congestive heart failure and the outcomes of invasive cardiac procedures across Canada. Data in the Atlas will be presented at a national, provincial and health region level. The Atlas will be published as a series of 20 articles and chapters in future issues of The Canadian Journal of Cardiology and on CCORT's web site (www.ccort.ca). The journal version of the Atlas chapters will be written for a clinical audience and will include editorials written by invited experts, whereas the web-based version of each chapter will be written for a more general audience and will include additional supplemental information (for example, interactive colour maps and tables) that cannot be included in the journal version. Material from the Journal and the web will eventually be compiled into a book that will be distributed across Canada. This article serves as an introduction to the Atlas project and describes the rationale for and objectives of the CCORT national cardiac Atlas project.
The Canadian Cancer Incidence Atlas is among recent national atlases using incidence rather than mortality data. Methods used to assess the significance and spatial correlation of the age-standardized rates (ASIRs) for the 290 census divisions are described. The expected number of cases by area was used to determine cancer sites with sufficient cases to be mapped. ASIR significance was assessed using a simulation based on a Poisson distribution. The consistency of the observed case distributions with the Poisson distribution was examined. The bootstrap confidence interval (CI) for the ASIR developed by Swift was used in the atlas. Spatial correlation was assessed with Moran's I/I(max) and the significance determined by a simulation in order to allow for area population variation. Data quality indicators typically used for cancer registries were presented, supplemented by a registry questionnaire.
Few paediatric cardiologists know of Maude Abbott. Yet before Helen Taussig, no one contributed more to founding the specialty than Maude Abbott. She achieved international fame as the early 20th century expert on cardiac malformations. We summarise here her life and contributions, indicating how she is more than justified in being inducted to the Hall of Fame.
The main facets of professor N.I. Pirogov's professional activity are outlined. Forensic medicine (in the first place its organizational and practical aspects) was an integral component of his scientific and clinical work, along with applied anatomy and surgery. Landmark publications of N.I. Pirogov are listed with special reference to those concerned with forensic medical expertise of medical malpractice cases, postmortem inspection and intravital examination procedures, wound ballistics studies, the atlas of forensic pathology, etc. The surgeon and anatomist N.I. Pirogov can be justly regarded as a founder of forensic medicine in this country.
