OBJECTIVES: Antiplatelet agents are commonly prescribed to reduce the risk of myocardial infarction, stroke and graft occlusion in patients with peripheral arterial disease (PAD). The objective was to summarise current evidence and provide recommendations on the use of antiplatelet agents in PAD. METHODS: A consensus group was assembled including 20 specialists from a variety of fields involved in the management of patients with PAD. Data was circulated in a systematic manner prior to a main consensus meeting held in November 2001. The document subsequently produced was circulated within the group to ensure agreement in the interpretation and presentation of its findings. RESULTS: Consensus recommendations are provided in 7 common or contentious scenarios in PAD. The recommendations are graded to reflect the evidence available and interpretations of the group. Although the document provides recommendations, it is stressed that they must be interpreted in the light of individual patient circumstances. CONCLUSION: Antiplatelet agents have an important role in the management of patient with PAD. Although this document provides consensus recommendations, the optimum treatment in many scenarios remains unclear due to a lack of focussed clinical trials in PAD.
Current nomenclature for atrioventricular junctions derives from a surgically distorted view, placing the valvar rings and the triangle of Koch in a single plane with antero-posterior and right-left lateral coordinates. Within this convention, the aorta is considered to occupy an anterior position, while the mouth of the coronary sinus is shown as being posterior. While this nomenclature has served its purpose for the description and treatment of arrhythmias dependent on accessory pathways and atrioventricular nodal re-entry, it is less than satisfactory for the description of atrial and ventricular mapping. To correct these deficiencies, a consensus document has been prepared by experts from the Working Group of Arrhythmias of the European Society of Cardiology, and the North American Society of Pacing and Electrophysiology. It proposes a new, anatomically sound, nomenclature that will be applicable to all chambers of the heart. In this report, we discuss its value as regards the description of the atrioventricular junctions, establishing the principles of this new nomenclature.

The scientific basis for human trials of hand transplantation was both experimental and clinical. Prolonged survival of limb transplants was achieved in small and large animals by using novel immunosuppressive drugs. Further, all tissue components of the hand (skin, muscle, tendon, nerve, bone, and joint) were individually transplanted with success in humans. After appropriate institutional review of the ethics, experimental data, treatment protocol, and informed consent, clinical trials were approved. Thirteen hands have been transplanted onto 10 recipients, with resultant low morbidity and no mortality. With the exception of one recipient who requested amputation after the second year, results of hand transplantation have been highly successful. Functional return mirrored that seen after hand replantation. The limbs were progressively integrated into activities of daily living and professional tasks. The hand and patient survival rate exceeds the initial results of any previously transplanted organ. This success strongly supports continuation of these human trials.

A Consensus Conference on the use of recombinant human erythropoietin (rHuEPO, epoetin alfa) in gynecologic tumors was held in Rome in March 1999, and an associated consensus paper has been published in Italian. The current paper updates several discussions that took place at the 1999 meeting concerning epoetin alfa treatment in breast, ovarian, and cervical cancers; the role of epoetin alfa in mobilizing progenitor hematopoietic cells; administration of epoetin alfa in combination with granulocyte colony-stimulating factor; and the effect of hemoglobin levels on outcome of radiation or chemoradiation treatment.

Intravenous immunoglobulin (IVIG) preparations are a mainstay for a number of disorders that include primary immuno-deficiency, acute inflammatory conditions, hematological disorders, infections, and neuroimmunological disorders. The range of therapeutic activity is attributed to IVIG's myriad action mechanisms. IVIG can interact and bind onto complement factors, which can prevent complement-mediated tissue damage, modulate T-lymphocytes, alter cytokine profiles, and modulate the immune system. These interactions can act alone or in combination to maintain immune balance while preserving homeostasis. A consensus panel was convened in 2000 to evaluate and define new advances in IVIG therapies.
