Tratamento médico do trauma e da compressão à medula espinhal de cães e gatos
A lesão traumática e/ou compressiva à medula espinhal de cães e gatos inicia uma série de eventos destrutivos que podem levar a conseqüências desastrosas e irreversíveis às funções motora e sensorial do animal. Estes casos devem ser considerados emergenciais, visto que a intervenção rápida e adequada, em intervalo de tempo apropriado, pode limitar a extensão dos danos ao tecido neuronal, favorecendo assim a recuperação neurológica. Em geral, o tratamento para a lesão medular envolve a utilização de agentes neuroprotetores, como o succinato sódico de metilpredinisolona, visando o controle das lesões secundárias, e em alguns casos a realização de cirurgia para descompressão da medula espinhal lesada, associada ou não à estabilização da coluna vertebral. 
Fisiopatologia do trauma e da compressão à medula espinhal de cães e gatos
O trauma medular é uma das entidades neurológicas mais freqüentes e mais graves na prática clínica por produzir lesões que podem levar a conseqüências irreversíveis à saúde do animal. A lesão à medula espinhal pode ser aguda ou crônica iniciando uma seqüência de eventos vasculares, bioquímicos e inflamatórios, que resultam no desenvolvimento de lesões teciduais secundárias, levando à destruição progressiva do tecido neuronal. A lesão aguda pode resultar de extrusão de disco intervertebral, êmbolo fibrocartilaginoso ou traumatismo vertebral, e pode provocar interrupção anatômica, compressão, concussão e/ou isquemia à medula espinhal. A lesão medular crônica pode vir acompanhada de compressão progressiva da medula espinhal e provir de protrusão de disco, neoplasias e instabilidade vertebral.  
Applicability of the cobb angle measurement in idiopathic scoliosis using scanned imaging
OBJECTIVES: To compare the measurement of the Cobb angle on printed radiographs and on scanned radiographs viewed through the software "PixViewer".
METHODS: Preoperative radiographs of 23 patients were evaluated on printed films and through the software "PixViewer". The same evaluator, a spine surgeon, chose the proximal and distal limiting vertebrae of the main curve on printed radiographs, without identification of patients, and measured the Cobb angle based on these parameters. The same parameters and measurements were applied to scanned radiographs. The measurements were compared, as well as the choice of limiting vertebrae.
RESULTS: The average variation of the Cobb angle between methods was 1.48 ± 1.73°. The intraclass correlation coefficient (ICC) was 0.99, demonstrating excellent reproducibility.
CONCLUSION: The Cobb method can be used to evaluate scoliosis through the "PixViewer" tool with the same reliability as the classic method on printed radiographs

Atividade física, qualidade de vida e depressão durante a gravidez
This study examines physical activity patterns among women, from pre-pregnancy to the second trimester of pregnancy, and the relationship between physical activity status based on physical activity guidelines and health-related quality of life (HRQoL) and depression over pregnancy. 56 healthy pregnant women self reported physical activity, HRQoL and depression at 10-15 and 19-24 weeks of pregnancy and physical activity before pregnancy. Whereas vigorous leisure physical activity decreased after conception, moderate leisure physical activity and work related physical activity remained stable over time. The prevalence of recommended physical activity was 39.3% and 12.5% in the 1st and 2nd trimesters of pregnancy respectively, and 14.3% pre-pregnancy. From the 1st to the 2nd pregnancy trimester, most
physical HRQoL dimensions scores decreased and only mental component increased, independently
of physical activity status. No changes in mean depression scores were observed. These data suggest
that physical activity patterns change with pregnancy and that physical and mental components
are differentially affected by pregnancy course, independently of physical activity status.Este estudo examina os padrões de atividade física antes
da concepção até o segundo trimestre de gravidez
e a relação entre o nível de atividade física, com base
nas recomendações de atividade física, a qualidade de
vida relacionada à saúde (QVRS) e depressão ao longo
da gravidez. Cinquenta e seis grávidas saudáveis reportaram
nível de atividade física, QVRS e depressão
às 10-15 e 19-24 semanas de gravidez, além de atividade
física antes da concepção. Enquanto a atividade
física vigorosa no lazer diminuiu depois da concepção,
as atividades físicas moderadas no lazer e no trabalho
mantiveram-se estáveis. A prevalência de atividade fí-
sica recomendada foi de 39,3%, 12,5% e 14,3% antes,
no primeiro e no segundo trimestres de gravidez, respectivamente.
Independentemente do estatuto de atividade
física, a maior parte dos escores nas dimensões
físicas da QVRS diminui do primeiro para o segundo
trimestre de gestação, e apenas o componente mental
aumenta. Não se verificaram alterações nos escores
médios de depressão. Estes dados sugerem que, com a
gravidez, há alteração nos padrões de atividade física;
além disso, os componentes físico e mental são diferentemente
afetados pelo curso da gestação, independentemente
do nível de atividade física

Understanding the clinical spectrum of complicated Plasmodium vivax malaria: a systematic review on the contributions of the Brazilian literature
The resurgence of the malaria eradication agenda and the increasing number of severe manifestation reports has contributed to a renewed interested in the Plasmodium vivax infection. It is the most geographically widespread parasite causing human malaria, with around 2.85 billion people living under risk of infection. The Brazilian Amazon region reports more than 50% of the malaria cases in Latin America and since 1990 there is a marked predominance of this species, responsible for 85% of cases in 2009. However, only a few complicated cases of P. vivax have been reported from this region. A systematic review of the Brazilian indexed and non-indexed literature on complicated cases of vivax malaria was performed including published articles, masters' dissertations, doctoral theses and national congresses' abstracts. The following information was retrieved: patient characteristics (demographic, presence of co-morbidities and, whenever possible, associated genetic disorders); description of each major clinical manifestation. As a result, 27 articles, 28 abstracts from scientific events' annals and 13 theses/dissertations were found, only after 1987. Most of the reported information was described in small case series and case reports of patients from all the Amazonian states, and also in travellers from Brazilian non-endemic areas. The more relevant clinical complications were anaemia, thrombocytopaenia, jaundice and acute respiratory distress syndrome, present in all age groups, in addition to other more rare clinical pictures. Complications in pregnant women were also reported. Acute and chronic co-morbidities were frequent, however death was occasional. Clinical atypical cases of malaria are more frequent than published in the indexed literature, probably due to a publication bias. In the Brazilian Amazon (considered to be a low to moderate intensity area of transmission), clinical data are in accordance with the recent findings of severity described in diverse P. vivax endemic areas (especially anaemia in Southeast Asia), however in this region both children and adults are affected. Finally, gaps of knowledge and areas for future research are opportunely pointed out
