Cardiac hemangioma of the right atrium

Primary cardiac tumors are rare, with an incidence range between 0.001% and 0.030% at autopsy. Recent technical advances have facilitated diagnosis and surgical treatment of such lesions. Patients with a resectable tumor usually have a good prognosis, but patients with an unresectable tumor may have a poor prognosis. This report shows a case of right atrial hemangioma growing like an extracardiac mass, with cardiac tamponade the only clinical presentation.

Reflexões sobre o conceito de atendimento humanizado em Odontologia

Humanization at dental care is highly important due to uneven relation between scientific / technical advances in dentistry and thequality of human contact. The dental treatment goes beyond the field of scientific knowledge. Therefore, the dental treatment requiresbalance among technical skill, scientific training, and humanist vision of health promotion. Contemporarily, humanization is understoodas tripod based on user's rights, dental practice and organization of a humanized model. Curriculum integration of ethical, humanistic,scientific and technical contents is an important and current challenge on teaching / learning process for professionals at Dentistry. Thispaper aims to, guided by the literature review, to present some considerations on human care in dentistry, with emphasis on theimportance of professional /patient relationship for promoting oral health. It is suggested that dentists reflect on the urgent need ontheoretical basis of humanization and patient-professional relationship for health care.Descriptors: Humanization of Assistance; Dental Staff

Natural fibers based composites - Technical and social issues

Brazil is the only country in South America to have an automotive supplier sector based on natural fibers. New opportunities are arising due to an increase demand by the car makers in applying natural fibers in their parts. Several crop fibers have been developed in Brazil. Among them can be listed caroa, piacava, pupunha, mutum and others of regional application. For the automotive industry, which requires large quantities with uniform quality, the alternatives are sisal (170,000 ton/yr), curaua (150 ton/yr in 2003), malva, 200 ton/yr; Brazil is the single largest producer country of sisal, and commercially, the only one in curaua. For South America, the alternatives are fique in Colombia, abaca in equator, flax in Argentina and curaua in Venezuela. It must be understood by the target countries of drugs, is that crop fiber can be an economic alternative to coca in the Andes region, therefore an instrument of land reform and drug reduction plantations. Several companies have a strong program of apply natural fibers based components in their products: Volkswagen do Brazil, DaimlerChrysler, General Motors do Brazil. Among their suppliers can be listed companies such Pematec (curaua), Toro (sisal, coir and jute), Incomer (sisal and jute), Ober (jute, curaua), Indaru (jute and sisal), Antolin (imported kenaf,) Tapetes Sao Carlos (sisal), Poematec (coir) and Art-Gore, with Woodstock'' wood and natural fibers). Figures about production and demand are discussed in the paper.
