Abstract This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado of Northern Brazil. Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate change scenarios for the year 2050. Potential refuge areas for conservation actions were identified, and evidence of the vulnerability of the flora was demonstrated based on the disparity between potential areas of climate stability amid current protected areas. The results suggested a lack of pattern between the scenarios and an idiosyncratic response of the species, indicating different impacts on plant communities and the existence of unequal stable alternative conditions, which could bring consequences to the ecological relationships and functionality of the floras. Even in the most pessimistic scenarios, most species presented an expansion of potential occurrence areas, suppressing or cohabiting with species of adjacent biomes. Typically marginal plants were the most sensitive. Overlapping adequate habitats are concentrated in the NBC. The analysis of habitats in relation to anthropized areas and PAs demonstrate low future effectiveness in the protection of these savannas.

O objetivo deste estudo foi estimar a prevalência, o conhecimento, o tratamento e o controle de hipertensão arterial sistêmica (HAS) na população urbana adulta de Tubarão, Santa Catarina, Brasil. Foi realizado um estudo transversal, com uma amostra estratificada a partir de uma listagem dos pontos de luz, do qual participaram 707 indivíduos maiores de 18 anos. Foi aplicado um questionário, aferidas duas medidas da pressão arterial por manômetro de mercúrio, em uma visita domiciliar conduzida por estudantes de medicina. A prevalência de HAS pelo critério do The Seventh Report of The Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (pressão arterial > 140 x 90mmHg) foi de 36,4% e de 40,5% quando acrescentados os indivíduos em uso de anti-hipertensivos. Tinham conhecimento da hipertensão 55,6%; estavam em tratamento farmacológico 46,8% e estavam com a pressão arterial controlada 10,1% dos hipertensos. A elevada prevalência estimada de hipertensão arterial e os percentuais de conhecimento sobre o diagnóstico, tratamento e controle aquém do ideal apontam para necessidade de ações preventivas em Tubarão.

The aim of this study was to estimate the prevalence, awareness, treatment, and control of systemic arterial hypertension in the adult urban population of Tubarão, Santa Catarina, Brazil. The cross-sectional approach used a stratified sample, based on an initial list of electric power connections, resulting in the selection of 707 individuals over 18 years of age. A questionnaire was applied and arterial blood pressure was measured twice by medical students during home visits, using a mercury sphygmomanometer. The prevalence of arterial hypertension based on the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (arterial pressure > 140 x 90mmHg) was 36.4%, increasing to 40.5% when including individuals on anti-hypertensive medication. Of the patients with high blood pressure, 55.6% were aware of their hypertension, 46.8% were on medication, and 10.1% had their blood pressure under control. The high estimated prevalence of hypertension, low level of unawareness, and less than ideal treatment and control levels emphasize the need for preventive measures in Tubarão.

É relatado um caso de paralisia periódica tireotóxica. Os autores chamam a atenção para o fato de não haver registro de publicações semelhantes na literatura brasileira nos 10 últimos anos. São abordados diversos aspectos do diagnóstico diferencial com outros tipos de paralisia periódica.

A case of thyrotoxic periodic paralysis based on clinical grounds, laboratory data and therapeutic response as well is reported. The authors comment on the differential diagnosis with the most frequent types of periodic paralysis. The importance of a correct diagnosis and treatment as early as possible is stressed as to prevent further development of permanent paralysis due to irreversible degenerative myofibril changes as stated in literature.

Os autores relatam caso de paciente masculino, de 6 anos de idade, hospitalizado com diagnóstico de meningite purulenta. A pneumencefalografia mostrou processo expansivo fronto-temporal esquerdo. A arteriografia carotídea bilateral demonstrou presença de aneurisma da artéria frontal ascendente, com hematoma circundante, à esquerda e, aneurisma da artéria temporal posterior, à direita. Cirurgia para evacuação do hematoma e clipagem do aneurisma foi realizada. O paciente piorou no pós-operatório e faleceu. A autópsia demonstrou a presença de hemorragia subaracnóide, hematoma fronto-temporal esquerdo e para-capsular direito. No interior do hematoma, à direita, evidencia-se massa arredondada, cujo exame histopatológico demonstrou tratar-se de paredes arteriais dilatadas, com intenso processo inflamatório supurativo. Os autores tecem considerações a respeito da frequência de aneurismas micóticos na infância, a multiplicidade dos mesmos, a sua etiopatogenia, a localização dos mesmos na árvore arterial intracraniana, do valor diagnóstico da angiografia carotídea e da indicação cirúrgica.

The case of a 6 year-old boy, who was hospitalized with the diagnosis of purulent meningitis is reported. The CSF examination disclosed pleocytosis and the antibioticotherapy was instituded. The bilateral carotid angiography demonstrated an arterial aneurysm of the frontal ascendent artery with hematoma in the left side, and another in the posterior temporal artery, in the right side. The patient was operated on because of the hematoma, in the left side. The condition of the patient in the post-operatory period deteriorated and the death ocurred. The post-mortem examination disclosed a sub-arachnoidal hemorrhage, fronto-temporal hematoma in the left side and a para-capsular hematoma in the right side. The histological examination of the central part of the hematoma revealed a dilated arterial walls with a supurative inflammatory process. The authors took in consideration the frequency of mycotic aneurysms in children, especially the multiplicity of them, the etiopathogeny and their localization in the intracranial arterial tree.

Os autores relatam um caso de hidroma subdural na fossa craniana posterior conseqüente a traumatismo na região occipital. O paciente foi operado com pleno sucesso. A raridade da localização de hidroma na fossa posterior é salientada, sendo discutidos os possíveis mecanismos etio-patogênicos.

A case of subdural hydroma in the posterior fossa is reported. The patient who had suffered an occipital traumatism was sucessfully operated. The rarity of the sub-tentorial hidromas is enphazised. The etiopathogenesis is discussed.
