Ultrasonography criteria for differentiating ACTH dependency from ACTH independency in 47 dogs with hyperadrenocorticism and equivocal adrenal asymmetry.

Background: Adrenal ultrasonography (US) in dogs with hyperadrenocorticism (HAC) is commonly used to distinguish adrenocorticotropic hormone (ACTH)-independent (AIHAC) and ACTH-dependent hyperadrenocorticism (ADHAC). To date, no cut-off values for defining adrenal atrophy in cases of adrenal asymmetry have been determined. Given that asymmetrical hyperplasia is sometimes observed in ADHAC, adrenal asymmetry without ultrasonographic proof of adrenocortical tumor such as vascular invasion or metastasis can be equivocal.

A global view of education and training in critical care medicine.

The Educational Committee of the World Federation of Societies of Intensive and Critical Care Medicine (WFSICCM) performed a survey in various countries and reviewed data from the Cobatrice study and from surveys of the Pan-American and Iberic Federation of Societies of Intensive and Critical Care Medicine to characterize current structures and processes in education in intensive care medicine to determine the potential for convergence to a common competency-based training program, and to a common competency certification in most countries around the world, guided by the local scientific societies and the WFSICCM. Training in critical care medicine sponsored by the WFSICCM should provide a competency approach that permits diversity of training methods while creating a common outcome: doctors with a universal set of knowledge, skills, and attitudes essential for a specialist in intensive care medicine.

Global distribution of infectious diseases requiring intensive care.

This article describes infectious diseases that are of special importance to intensivists. The emphasis on epidemiology notwithstanding, it also addresses clinical, diagnostic, and treatment issues related to each infection described. The discussion avoids terrorism-related aspects of these infections, because they were very well covered in the October 2005 issue of the Critical Care Clinics.

First human case of retrograde transcatheter implantation of an aortic valve prosthesis.

The transcatheter route is an emerging approach to treating valvular disease in high-risk patients. The 1st clinical antegrade transcatheter placement of an aortic valve prosthesis was reported in 2002. We describe the first retrograde transcatheter implantation of a new aortic valve prosthesis, in a 62-year-old man with inoperable calcific aortic stenosis and multiple severe comorbidities.
