OBJECTIVES:To analyze the operative time, length of hospitalization and cost, as well as the bleeding and pain observed during the postoperative period, of thyroidectomy procedures using vessel sealing, harmonic scalpel or the conventional technique.METHODS:Retrospective analysis of thyroidectomies performed between 2007 and 2010 using either the conventional technique or minimally invasive techniques involving vessel sealing or a harmonic scalpel. Gender, age, primary diagnosis and procedure type were analyzed. The outcomes analyzed included the length of the procedure, length of hospital stay, […]

ABSTRACT Since 2004, the Brazilian government has run one of the most all-inclusive hearing rehabilitation program based on hearing aids worldwide. In 2007 this investment in hearing aids topped U$ 68 million, apart from covering the cost of physicians and audiologists. Nearly 140 centers are certified by the government to dispense fitted hearing aids, figures which are still low when one considers the size of the country. Telemedicine can represent a field of knowledge which broadens hearing rehabilitations services in […]

ABSTRACTMarkov Chains provide support for problems involving decision on uncertainties through a continuous period of time. The greater availability and access to processing power through computers allow that these models can be used more often to represent clinical structures. Markov models consider the patients in a discrete state of health, and the events represent the transition from one state to another. The possibility of modeling repetitive events and time dependence of probabilities and utilities associated permits a more accurate representation […]
