Objective: to describe technical complaints and adverse drug events reported in a sentinel hospital in São Paulo state in 2009 and 2010. Methods: This is a descriptive study. Information was obtained from the sentinel hospital Risk Management database. Results: we found 199 reports related to drugs: 70.0% were technical complaints, 21.0% ineffective therapy and 9.0% adverse reaction to medication. The pharmacological groups with highest number of reports were: drugs that act on alimentary tract and metabolism (25.1%), the nervous system (25.1%) and anti-infective drugs for systemic use (22.1%). Conclusion: technical complaints and adverse drug events were frequent, despite recognized underreporting. The characterization of these events could inform the adoption of control measures and permanent educational actions in health services in order to prevent their occurrence.

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

O núcleo leito da estria terminal (NLET) é uma estrutura límbica localizada no prosencéfalo rostral, no qual constitui uma importante região no circuito neural das respostas comportamentais e fisiológicas a estímulos aversivos. Estudos anteriores demonstraram o envolvimento do NLET nas respostas cardiovasculares desencadeados por estímulos aversivos. No entanto, os mecanismos neuroquímicos locais envolvidos nesse controle pelo NLET ainda são pouco compreendidos. O glutamato é um importante neurotransmissor excitatório no SNC, e evidências têm apontado que a neurotransmissão glutamatérgica é um importante mecanismo neuroquímico envolvido no controle das respostas fisiológicas durante o estresse em várias estruturas límbicas. Entretanto, um possível envolvimento da neurotransmissão glutamatérgica do NLET nas respostas cardiovasculares ao estresse nunca foi investigado. Assim, o objetivo do presente estudo foi estudar o envolvimento da neurotransmissão glutamatérgica no NLET nas respostas autônomas observadas durante o estresse de restrição agudo em ratos. Nós observamos que a microinjeção bilateral no NLET de LY235959 (antagonista seletivo do receptor glutamatérgico NMDA) reduziu a resposta taquicárdica desencadeada pelo estresse de restrição, porém não afetou as respostas pressora e de redução da temperatura cutânea da cauda. O tratamento bilateral do NLET com NBQX (antagonista seletivo de receptores glutamatérgicos não-NMDA) reduziu a resposta taquicárdica e a de redução da temperatura cutânea desencadeadas pelo estresse de restrição, porém sem interferir com a resposta pressora. Dessa forma, nossos dados sugerem que a neurotransmissão glutamatérgica do NLET tem uma influência facilitatória nas respostas taquicárdica e de vasoconstrição cutânea induzidas pelo estresse.

The minimization and mitigation of environmental impacts caused by the activities of organizations is increasingly becoming a key concern due to factors such as market demand, including suppliers and consumer markets, quality standards and even marketing strategies. The implementation of an EMS - Environmental Management System - allows the organization to achieve the level of environmental performance for its determined and promotes continuous improvement over time. This system consists of a schedule of activities, so as to eliminate or minimize impacts to the environment through preventive actions. It also provides a structured approach to set and achieve goals and objectives, and to establish procedures, work instructions and control, ensuring that the implementation of the policy can become reality. The objective of this work consists in planning a system using environmental management based on the ISO 14001 - standard internationally more widespread and accepted in the requirements to establish and operate an EMS - the Central Library, UNESP, Rio Claro / SP to stimulate the quest for continuous improvement and sustainability in the educational institution. For making the diagnosis of this planning was used the PDCA methodology, suggested by the standard, as well as all requirements for compliance. The results show that the benefits that the organization will receive involve reducing expenses and cost of energy and water, and improve the organization's reputation before the whole university and other educational institutions, reaching about three thousand people on university
