Coronary Microvascular Disease in Chronic Chagas Cardiomyopathy Including an Overview on History,Pathology, and Other Proposed Pathogenic Mechanisms

This review focuses on the short and bewildered history of Brazilian scientist Carlos Chagas''s discovery and subsequent developments, the anatomopathological features of chronic Chagas cardiomyopathy (CCC), an overview on the controversies surrounding theories concerning its pathogenesis, and studies that support the microvascular hypothesis to further explain the pathological features and clinical course of CCC. It is our belief that knowledge of this particular and remarkable cardiomyopathy will shed light not only on the microvascular involvement of its pathogenesis, but also on the pathogenetic processes of other cardiomyopathies, which will hopefully provide a better understanding of the various changes that may lead to an end-stage heart disease with similar features. This review is written to celebrate the 100th anniversary of the discovery of Chagas disease.     

Experiences with Evaluation Procedures in Pathology Teaching at Dalhousie University

The experience of evaluation of both students and course in pathology at Dalhousie Medical School indicates that valuable reproducible and probably objective information is obtained by the use of frequent multiple-choice tests combined with substantial final oral examinations. Course evaluation by student questionnaires has provided useful information on course modifications and teaching techniques. The most informative feature of the evaluation program is in the provision of mechanisms for feedback from students to faculty and among faculty members. By these means weaknesses in teaching have been identified and often corrected. The method has aided in the early identification of poor students and of their areas of weakness so that remedial instruction can be instituted before the final examination.     

Recent Advances in Structural Research on Ether Lipids from Archaea Including Comparative and Physiological Aspects

A great number of novel and unique chemical structures of archaeal polar lipids have been reported. Since 1993, when those lipids were reviewed in several review articles, a variety of core lipids and lipids with unique polar groups have been reported successively. We summarize new lipid structures from archaea elucidated after 1993. In addition to lipids from intact archaeal cells, more diverse structures of archaea-related lipids found in environmental samples are also reviewed. These lipids are assumed to be lipids from unidentified or ancient archaea or related organisms. In the second part of this paper, taxonomic and ecological aspects are discussed. Another aspect of archaeal lipid study has to do with its physiological significance, particularly the phase behavior and permeability of archaeal lipid membranes in relation to the thermophily of many archaea. In the last part of this review we discuss this problem.     

The UEMS Section/Board of Pathology,Chapter 6: Requirement for Recognition of Postgraduate Training in Pathology: a presentation of the Paris Document

M. Tötsch, C. Cuvelier, L. Vass and A. Fassina and on behalf of the participants of the UEMS Section/Board of Pathology meeting in Paris 2012
The UEMS Section/Board of Pathology, Chapter 6: Requirement for Recognition of Postgraduate Training in Pathology: a presentation of the Paris Document After more than five years discussion the UEMS Section/Board of Pathology agreed a specification of requirements for recognition of post‐graduate training in pathology, which is the key to the future of our discipline. The document published here, subject to ratification by UEMS Council, was voted on and accepted by the Pathology Board at the UEMS Paris meeting of 9 June 2012. Cytopathology is regarded as integral part of pathology: in general, training in pathology takes five years and maintains a common trunk of four (minimum three) years where surgical pathology, autopsy pathology and basic knowledge of neuropathology, dermatopathology and cytopathology are adequately trained and assessed. Training in so‐called ‘areas of interests’ covers the remaining 12–24 months. Certificates of ‘advanced level of competence’ remain within the authority of national boards. As senior members of its Executive Board, we believe that the European Federation of Cytology Societies (EFCS) should take responsibility for establishing 1) standards in the quality of cytopathology training, 2) training guidelines and qualification for advanced levels of competence in cytopathology, 3) manpower planning, 4) tutorials for pathologists and cytotechnologists and 4) standards of cytotechnologist training.
