The majority of demands for drugs that have led to legal proceedings could be avoided if two SUS directives were followed, namely the organization of oncology services and the observance of reporting on essential medicines. Failure to do so causes a breakdown in the National Drug Policy, in equality of access and in the rational use of drugs within the National Health System.

Neste momento de crise financeira do Estado, é importante o uso adequado dos recursos econômicos disponíveis, e este trabalho objetiva estudar os fatores que determinam o aumento dos gastos em saúde; é uma revisão crítica do tema, com um levantamento sistemático das publicações dos últimos dez anos, considerando-se os principais estudiosos da disciplina da economia da saúde no Brasil e de outros países. Os fatores que agem na demanda por serviços de saúde são de natureza variada, podendo se sobrepor, o que aumenta ainda mais a demanda: necessidade sentida, fatores psicossociais, seguridade social, demografía, epidemiología, utilização dos serviços, regulamentação e fatores culturais. Os que agem na oferta da assistência à saúde são: progresso técnico-médico, difusão da inovação e multiplicação dos centros de assistência à saúde. Os fatores da demanda não podem ser rapidamente contidos, enquanto que os de oferta são muito mais facilmentecontrolados, mas são poucos os exemplos encontrados na literatura sobre o sucesso das medidas de controle.

What is the expected impact on horticulture?• The use of LEDs, especially the blue one, can be considered as an interesting tool to enhance productivity of strawberry cultivated under protected conditions. The way of LEDs use (alone or in combination with other light sources) and timing (phenophases) have to be further investigated prior to a commercial implementation of this lighting system.

The inadequate use of drugs leads to lack of therapeutic efficacy, adverse reactions, side effects, preventable drug interactions, increased bacterial resistance to antibiotics, and wasted resources. Changing this scenario is one of the most complex challenges facing health systems today. One approach used to rationalize the use of drugs lies in the creation of pharmacy and therapeutics committees, whose main role is to guide and assist health institutions at all levels in selecting drugs and monitoring their use, training professionals to use drugs rationally, and collecting systematized information to guide new strategies and actions. Brazil, unlike other parts of the world, does not make it compulsory to have pharmacy and therapeutics committees. Although committees for monitoring hospital infections are compulsory in that country, their action is restricted to hospitals and is not as broad as that proposed for pharmacy and therapeutics committees. Data from 2003 shows that among 250 public and private hospitals in Brazil, only 29 had pharmacy and therapeutics committees. It is essential that the need to make these committees compulsory at all levels of the Brazilian health system be discussed, and that the national Ministry of Health and other related agencies create the conditions necessary for the establishment of pharmacy and therapeutics committees, in accordance with other health policies currently in place.
