Contribuição para o estudo do significado da evolução do coeficiente de mortalidade infantil no município de São Paulo, SP (Brasil) nas três última décadas (1950-1979)

Buscando contribuir ao estudo da relação evolução da mortalidade infantil - evolução da qualidade de vida, foram examinadas no município de São Paulo as correlações existentes nas três últimas décadas entre as séries históricas da mortalidade e as séries históricas do valor do salário mínimo e da cobertura do abastecimento público de água. Estes dois últimos, salário e água, entendidos como fatores de maior e menor abrangência para o conjunto das condições de vida da população. O descenso da mortalidade na década de 50 e o ascenso da mesma na década de 60 estiveram significativamente relacionados à evolução do salário-mínimo real. Entretanto, a evolução da mortalidade na década de 70, com importante queda a partir de 1974, esteve relacionada especificamente à evolução do abastecimento de água. Conclui-se que no período 1950-1979 são diferentes as implicações para a qualidade de vida que podem ser tiradas a partir da evolução da mortalidade infantil e que parece equivocado afirmar-se que a reversão das altas mortalidades a partir de 1974 tenha significado idêntica reversão na deterioração das condições de vida que ensejaram o ascenso da mortalidade no período anterior.

Tendência da mortalidade por doenças cerebrovasculares em adultos maiores de 20 anos de idade no Município de São Paulo (Brasil), 1950 a 1981

É descrita a evolução da mortalidade por doenças cerebrovasculares de adultos acima de 20 anos. residentes no Município de São Paulo, SP (Brasil), de 1950 a 1981, mediante a análise dos coeficientes de mortalidade por sexo e idade. Esta mortalidade é sempre maior em todas as idades para o sexo masculino e crescente com a idade. Entre 1970 e 1981, evidencia-se declínio de 17,3% para ambos os sexos (17,8% para homens e 16,8% para mulheres) que não foi atribuído a artefatos. Sugerem-se outros estudos para analisar as causas desse declínio.

Possible consequences of increasing life expectancy in Brazil: the perspective of a European historical demographer

Those over sixty years of age accounted for 6.6% of the total population of Brazil in 1985, in the Federal Republic of Germany this proportion was 20.3% in 1984. As early as 1950 it had been 14.5%. This proportion will not even be reached in Brazil in the year 2000 when persons aged sixty years and older are only projected to make up 8.8% of the total population. Similarly, in 1982/84 life expectancy at birth in the Federal Republic was 70.8 years for men and 77.5 for women; in Brazil the figures for 1980/85 were, by contrast, "only" 61.0 and 66.0. Against this background it is easy to understand why the discussion concerning an ageing society with its many related medical, economic, individual and social problems has been so slow in coming into its own in Brazil. As important as a more intensive consideration of these aspects may be in Brazil at present, they are, nevertheless, only one side of the story. For a European historical demographer with a long-term perspective of three of four hundred years, the other side of the story is just as important. The life expectancy which is almost ten years lower in Brazil is not a result of the fact that no one in Brazil lives to old age. In 1981 people sixty-five years and older accounted for 34.4% of all deaths! At the same time infants accounted for only 22.1% of total mortality. They are responsible, along with the "premature" deaths among youths and adults, for the low, "average" life expectancy figure. In Europe, by contrast, these "premature" deaths no longer play much of a role. In 1982/84 more than half of the women (52.8%) in the Federal Republic of Germany lived to see their eightieth birthdays and almost half of the men (47.3%) lived to see their seventy-fifth. Our biological existence is guaranteed to an extent today that would have been unthinkable a few generations ago. Then, the classic troika of "plague, hunger and war" threatened our forefathers all the time and everywhere. The radical transition from the formerly uncertain to a present-day certain lifetime, which is the result of the repression of "plague, hunger and war", led to unexpected consequences for our living together. Our forefathers were forced to live in closely knit Gemeinschaften in the interest of physical survival and to subordinate their egoistic goals to a common value, but now these pressures have, for the most part, fallen away. Correspondingly, this much more certain EGO has taken center stage. An ever greater number of us chooses to live life as single beings: the number of marriages is lower every year; the number of divorces is on the increase; in Berlin (West) more than half (sic! 52.3%) of all households are already composed on only one person. For the last dozen years the annual number of births in the Federal Republic has been insufficient to ensure population replacement. Not a population explosion but rather the opposite, a population implosion, is our problem. Human beings do not appear to be "social animals", as was axiomatically assumed for so long. They were only forced to behave as such for as long as "plague, hunger and war" forced them to do so. When these life endangering conditions no longer exist and life becomes certain even without their being integrated into a Gemeinschaft then humans suddenly show themselves more and more to be independent single beings. It is not the percentage of the population that is over sixty or sixty-five that is decisive in this context but rather how certain adults perceive their biological lives to be, since they are the ones who organize their lives, who build communities or who are ever more often willing only to enter into means-to-an-end personal unions without lasting or close ties and mutual responsibilities. There are many signs which seem to point to a development in this direction in Brazil as well. More and more adults in Brazil are caught up in the deep-seated transition from an uncertain to a certain lifetime. A third of them die after having reached their sixty-fifth birthday. It therefore seems to me to be high time that one began to give more consideration to the other side of the story in Brazil as well. And who is more suited intensively to consider the long-term perspectives than those engaged in the public health sector in whose competence, after all, such aspects, as "life certainty", "life expectancy" and "age at death" belong?

Motivos de no vacunación: un análisis crítico de la literatura internacional, 1950-1990

En muchos países se reconoce que los programas de vacunación requieren del dominio de elementos técnicos y organizacionales para ser accesibles a las poblaciones. Uno de ellos ha sido menospreciado de manera importante: la participación de la población y las causas que la motivan. El presente trabajo analiza experiencias de diversos países, a partir de una revisión bibliográfica del período 1950-1990. Los resultados muestran que los estudios existentes varían en su enfoque metodológico y conceptual de acuerdo a la región del mundo en donde fueron realizados y de acuerdo al tipo de investigador. Este hecho se explica por el supuesto que existe en muchos investigadores de pensar que conocen a profundidad los determinantes ideológicos de la conducta de las culturas de las que son nativos. A partir de ello utilizan metodologías que apenas les permiten aproximarse a un nivel superficial del conocimiento de la realidad social para hacer inferencias de la respuesta de las poblaciones ante la oferta de las vacunas.

Tendência secular da altura na idade adulta de crianças nascidas na cidade de São Paulo entre 1950 e 1976

OBJETIVO: Estimar a tendência/mudança secular das estaturas de jovens do sexo masculino, aos 18 anos de idade, nascidos na cidade de São Paulo, SP, entre 1950 e 1976. MÉTODOS: Foi coletada amostra aleatória e representativa de 6.942 indivíduos avaliados no alistamento militar. A análise estatística compreendeu a avaliação da normalidade da distribuição estatural (teste de Shapiro-Wilk) e a análise da tendência pelas técnicas de regressão linear. RESULTADOS/CONCLUSÕES: A distribuição das estaturas foi considerada normal para todas as coortes. O aumento total das estaturas foi de 3,42 centímetros ao longo dos 27 anos do estudo (1,26 cm/década). A tendência no período não foi linear, havendo aumento significativo na década de 50 (0,84 cm/década), aumento não significativo na década de 60 (0,5 cm/década) e aumento expressivo no período 1970-76 (2,9 cm/década). O ritmo de mudança secular observado é comparável ao de outros países e estados do Brasil. As coortes mais recentes (1975 e 1976) atingiram a maior estatura (~175 cm); contudo, este valor ainda indica déficits de 1,8 cm e 6,2 cm quando comparado às estaturas de jovens americanos nascidos em 1961 (NCHS) e holandeses em 1972. Mantidas as aceleradas taxas de mudança secular da década de 70, os jovens paulistas poderão recuperar estes déficits entre uma a três décadas. Isto indica a necessidade de contínua monitoração da tendência secular das alturas na cidade de São Paulo.

Skin lesions in envenoming by cnidarians (Portuguese man-of-war and jellyfish): etiology and severity of accidents on the Brazilian coast

This work attempts to establish dermatological identification patterns for Brazilian cnidarian species and a probable correlation with envenoming severity. In an observational prospective study, one hundred and twenty-eight patients from the North Coast region of São Paulo State, Brazil were seen between 2002 and 2008. About 80% of these showed only local effects (erythema, edema, and pain) with small, less than 20 cm, oval or round skin marks and impressions from small tentacles. Approximately 20% of the victims had long, more than 20 cm, linear and crossed marks with frequent systemic phenomena, such as malaise, vomiting, dyspnea, and tachycardia. The former is compatible with the common hydromedusa from Southeast and Southern Brazil (Olindias sambaquiensis). The long linear marks with intense pain and systemic phenomena are compatible with envenoming by the box jellyfish Tamoya haplonema and Chiropsalmus quadrumanus and the hydrozoan Portuguese man-of-war (Physalis physalis). There was an association between skin marks and probable accident etiology. This simple observation rule can be indicative of severity, as the Cubozoa Class (box jellyfish) and Portuguese man-of-war cause the most severe accidents. In such cases, medical attention, including intensive care, is important, as the systemic manifestations can be associated with death.

Observações sobre oviposição, eclosão e tempo de vida de Triatoma matogrossensis Leite & Barbosa, 1953 (Hemiptera-Reduviidae) em função da alimentação em pombos e coelhos

Estudou-se em laboratório a influência de duas diferentes fontes de alimentação sobre oviposição, eclosão dos ovos e tempo de vida de casais de Triatoma matogrossensis. Foram observados 68 casais separados em quatro diferentes grupos, com 20, 12, 20 e 16 casais, respectivamente. Os grupos A1 e A 2 foram alimentados em pombos e os grupos C1 e C 2 em coelhos. Os casais foram mantidos em estufa a 26o ± 2oC e UR de 60-80%, com fotoperíodo de 14 horas. O maior número de ovos postos foi encontrado no grupo A1. Não houve diferença na proporção de ovos eclodidos dos grupos alimentados em coelhos ou pombos. Não foram observadas diferenças de tempo de vida entre machos e fêmeas dos quatro grupos, entretanto o grupo A1 apresentou o maior tempo de sobrevivência e o grupo C2 o menor.

An outbreak of Portuguese man-of-war (Physalia physalis - Linnaeus, 1758) envenoming in Southeastern Brazil

Introduction Portuguese man-of-war, Physalia physalis (Linnaeus, 1758), are cnidarians capable of discharging intracellular organelles filled with venom, resulting in severe envenomation in humans. Methods We report the clinical and therapeutic aspects of 331 accidents involving Portuguese man-of-war in an outbreak on the coast of the State of São Paulo, Brazil. Results The clinical manifestations of envenomation were rare and mild and mostly local, systemic reactions; there was a low rate of late complications. Conclusions The consequences of envenomation were of moderate severity, and first aid measures were effective in controlling the pain. Outbreaks of accidents involving Portuguese man-of-war occur periodically in the area without a clear explanation.

Tendência da mortalidade por doenças do aparelho circulatório no Brasil: 1950 a 2000

FUNDAMENTO: As doenças do aparelho circulatório (DAC), um dos mais importantes problemas de saúde da atualidade, apesar de proporcionalmente ainda liderarem as estatísticas de morbi-mortalidade, começam a apresentar tendência declinante da mortalidade em diversos países. OBJETIVO: Analisar a tendência da mortalidade por DAC nas capitais brasileiras, no período de 1950 a 2000. MÉTODOS: Estudo de série temporal das razões de mortalidade padronizadas por DAC. Utilizamos dados secundários de óbitos dos anuários estatísticos do IBGE e do Sistema de Informação de Mortalidade. Realizamos análise de tendência linear das razões de mortalidade padronizadas por DAC nas capitais brasileiras que apresentaram séries completas de mortalidade, considerando os anos censitários do período do estudo (1950 a 2000). RESULTADOS: Apesar de proporcionalmente as DAC representarem a primeira causa de óbito na população brasileira, bem como apresentarem crescimento proporcional no período de análise deste estudo, o risco de óbito, representado pelas razões de mortalidade padronizadas, apresenta-se em decréscimo, particularmente a partir da década de 80. Destacam-se as cidades de Fortaleza, Salvador, Belo Horizonte, Rio de Janeiro e São Paulo, que apresentam razões de mortalidade padronizadas elevadas, porém em decréscimo (p < 0,05 e p < 0,10) desde o início do período analisado. CONCLUSÃO: O comportamento do risco de óbito por DAC sugere que esse grupo de enfermidades é o que primeiro se estabelece, acompanhando o aumento da industrialização no Brasil, verificado a partir da década de 1930 e após a Segunda Guerra Mundial, Como ocorreu em São Paulo e Rio de Janeiro, que historicamente experimentaram um processo de desenvolvimento e urbanização anterior e diferenciado em relação às outras capitais.

Biologia da Arsenura xanthopus (Walker, 1855) ( Lepidoptera - Adelocephalidae ), praga do «Açoita-Cavalo» (Luehea spp.) e notas sôbre seus inimigos naturais

Biology of Arsenura xanthopus (Walker, 1855) (Lep., Adelocephalidae), a pest of Luehea spp. (Tiliaceae), and notes on its natural enemies. In the beginning of 1950, one of the Authors made some observations about the biology of Arsenura xanthopus (Walker), in Piracicaba, State of S. Paulo, Brazil. From 1951 to 1953, both Authors continued the observations on such an important Adelocephalidae, the caterpillars of which represent a serious pest of Luehea spp. leaves. Actually, in some occasions, the caterpillars can destroy completely the leaves of the trees. The species is efficientely controlled by two natural enemies: an egg parasite (Tetrastichus sp., Hym., Eulophidae) and a fly attacking the last instar caterpillar (Winthemia tricolor (van der Wulp), Dip., Tachinidae). Tetrastichus sp. can destroy 100% of the eggs and the fly, 70 to 100% of the caterpillars. Indeed, facts as such are very interesting because we rarely know of a case of so complete a control of a pest by an insect. A. xanthopus had not yet been mentioned in our literature. Actually neither the systematic bibliography nor the economic one has treated of this species. However, a few other species of Arsenura are already known as living on Luehea spp. According to the Authors' observations, W. tricolor was also unknown by the Brazilian entomological literature. Arsenura xanthopus (Walker, 1855) After giving the sinonimy and a few historical data concerning the species, and its geographical distribution, the Authors discuss its placing in the genus Arsenura Duncan or Rhescyntis Huebner, finishing by considering Arsenura xanthopus as a valid name. The Authors put the species in the family Adelocephalidae, as it has been made by several entomologists. The host plant The species of Tiliaceae plants belonging to the genus Luehea are called "açoita-cavalo" and are well known for the usefulness of their largely utilized wood. The genus comprises exclusively American plants, including about 25 species distributed throughout the Latin America. Luehea divaricata Mart, is the best known species and the most commonly cultivated. Biology of Arsenura xanthopus Our observations show that the species passes by 6 larval stages. Eggs and egg-postures, all the 6 instars of the caterpillars as well as the chrysalid are described. The pupal period is the longest of the cycle, taking from 146 to 256 days. Data on the eclosion and habits of the caterpillars are also presented. A redescription of the adult is also given. Our specimens agreed with BOUVIER's description, except in the dimension between the extremities of the extended wings, which is a little shorter (107 mm according to BOUVlErVs paper against from 80 to 100mm in our individuals). Winthemia tricolor (van der Wulp, 1890) Historical data, geographical distribution and host are first related. W. tricolor had as yet a single known host-; Ar^-senura armida (Cramer). This chapter also contains some observations on the biolcn gy of the fly and on its behaviour when trying to lay eggs on the caterpillars' skin. The female of W. tricolor lays from 1 to 33 eggs on the skin of the last instar caterpillar. The mam region of the body where the eggs are laid are the membranous legs. Eggs are also very numerous oh the ventral surface of the thorax and abdomen. The. preference for such regions is easily cleared up considering the position assumed by the caterpillar when fixed motionless in a branch. In such an occasion, the fly approaches, the victim, puts the ovipositor out and lays the eggs on different parts of the body, mainly on the mentioned regions, which are much more easily reached. The eggs of the fly are firmly attached to the host's skin, being almost impossible to detach them, without having them broken. The minute larvae of the fly enter the body of, the host when it transforms into chrysalid. Chrysalids recentely formed and collected in nature f requentely show a few small larvae walking on its skin and looking for an adequate place to get into the body. A few larvae die by remaining in the skin of the caterpillar which is pushed away to some distance by the active movements of the chrysalid recentely formed. From 1 to 10 larvae completely grown may emerge from the attacked chrysalid about 8 days after their penetrating into the caterpillars' body and soon begin to look for an adequate substratum where they can transform themselves into pupae. In natural conditions, the metamorphosis occurs in the soil. The flies appear within 15 days. Tetrastichus sp. This microhymenoptera is economically the most interesting parasite, being commonly able to destroy the whole pos^ ture of the moth. Indeed, some days after the beginning of the infestation of the trees, it is almost impossible to obtain postures completely free of parasites. The active wasp introduces the ovipositor into the egg of the moth, laying its egg inside, from 80 to 120 seconds after having introduced it. A single adult wasp emerges from each egg. Sarcophaga lambens Wiedemann, 1830 During the observations carried out, the Authors obtained 10 flies from a chysalid that were recognized as belonging to the species above. S. lambens is a widely distributed Sarcophagidae, having a long list of hosts. It is commonly obtained from weak or died invertebrates, having no importance as one of their natural enemies. Sinonimy, list of hosts and distribution are presented in this paper. Control of Arsenura xanthopus A test has been carefully made in the laboratory just to find out the best insecticide for controlling A. xanthopus caterpillars. Four different products were experimented (DDT, Pa-rathion, BHC and Fenatox), the best results having been obtained with DDT at 0,25%. However, the Authors believe in spite of the initial damages of the trees, that the application of an insecticide may be harmful by destroying the natural agents of control. A biological desiquilibrium may in this way take place. The introduction of the parasites studied (Tetrastichus sp. and Winthemia tricolor) seems to be the most desirable measure to fight A. xanthopus.

Sombreamento dos cafèzais I.: resultados de três ciclos bienais (1953/1958) obtidos na escola "Luiz de Queiroz"

The present paper discusses the data obtained in shade and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results, analysed statistically, can be summarized as follows: a) unshaded plots produced 17% more than shaded ones; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green (not ripened fruits) depends of the harvest time. When the harvest was retarded, the percentage of green fruits was higher in the shaded plots. When the percentage of green fruits was the same, both in shaded and unshaded plots, the percentage of ripened was higher and the percentage of dried fruits was lesser in the shaded plots as compared with unshaded ones; d) other comparisons as production of dried grains by the field fruits, relation between dried fruits and dried grains and cup-test by expert coffee-taster, did not show differences among shaded and unshaded plots.

Taxonomic redescription of the Portuguese man-of-war, Physalia physalis (Cnidaria, Hydrozoa, Siphonophorae, Cystonectae) from Brazil

Although Physalia physalis (Linnaeus, 1758) is widely known from the Brazilian waters, specimens from this coast were never properly described. We describe Brazilian specimens of P. physalis including information on morphology, cnidome, SEM, and histological studies. Taxonomical issues concerning the development of the colonies and eventual synonymy with Physalia utriculus (La Martinière, 1787) are also added.
