Tafonomia de moluscos fósseis do Grupo Bauru (Cretáceo Superior, Bacia Bauru), na região do município de Monte Alto, São Paulo, Brasil

Bivalves mollusks fossils of Bauru Group (Late Cretaceous, Bauru Basin) deposited in scientific collections and collected in outcrops from Monte Alto municipality, São Paulo, are analyzed in their taphonomy. The preservation of recrystallized individual in carbonatic matrix indicates substrate remobilization by unidirectional energetic event in fluvial discharge. The specimens with conjugated valves possess internal sediment similar to the external indicating low exposition to Taphonomical Active Zone, suggesting a bioclastic low time-averaging. The truncate and fragmented posterior portion of specimens from scientific collections is probably related to the incapacity of the taxa to reburrowing the substrate in drowning periods. Both taphonomic patterns corroborate evidences of a fluvial paleoenvironment in the Bauru Group.

Piranha Attacks on Humans in Southeast Brazil: Epidemiology, Natural History, and Clinical Treatment, with Description of a Bite Outbreak

There are many tales describing ferocious schools of piranha attacking humans, but there are few scientific data supporting such behavior. The very few documented instances of humans attacked and eaten by piranha schools include 3 that occurred after death by other causes (eg, heart failure and drowning). These predaceous fishes, however, do occasionally injure bathers and swimmers in lakes and rivers. The characteristic profile of most injuries is a single bite per victim, generally related to the fish defending its brood. This paper describes an outbreak of piranha bites in a dammed river portion in southeast Brazil. The outbreak was caused by the speckled piranha, Serrasalmus spilopleura, a widespread species which benefits from the growing tendency of damming rivers all over Brazil. This article focuses on the epidemiological and clinical aspects of the injuries, as well as on piranha biology, to gain a better understanding of the natural history of bite outbreaks.

Evolução do rifteamento e paleogeografia da margem Atlântica Equatorial do Brasil: Triássico ao Holoceno

The Equatorial Atlantic Margin evolved from three rift systems recorded by a complex set of sedimentary basins developed since Upper Triassic to the Lower Cretaceous (Albian). The first rift system formed Foz do Amazonas Basin in Upper Triassic; the second phase formed Marajó Basin in Berriasian, a new rift in Foz do Amazonas Basin in Valanginian and Bragança-Viseu, Ilha Nova, São Luís e Barreirinhas basins in Aptian; the third phase formed Barreirinhas and Pará- Maranhão basins and a new rifting in the Foz do Amazonas Basin between the Aptian and Albian and evolved to continental break up. The main paleostress field during rift evolution was NE-SW and after the continental break up took the E-W direction, from the development of transform zones in the oceanic crust. From Miocene, South America was subjected to intraplate tectonics, which resulted in formation of E-W transcurrent faults that generated transtensive and transpressive segments that formed sedimentary basins and hills, resulting in changes in the drainage network. In Quaternary the landscape was modified by the last ice age that changed the sea level; the coastal drainage network was drowning resulting in the formation of the current line coast.

High incidence of preventable deaths during childhood in Porto Velho, Rondonia - Brazil

Background: We aimed to estimate and analyze epidemiological profile of deaths during childhood. Method: We used the databases of deaths provided by Information System of mortality between 2006 and 2010. We selected only those records where the occurrence of deaths corresponded to Porto Velho city and those who were aged between 12 and 48 months old at the moment of death. We examined only deaths from preventable causes and poorly defined. Results: The total number of deaths was estimated to be 103, 48.6% male. High frequencies of deaths occurred (39.8%) in children before reaching two years old. Vast majority of deaths (66.9%) was due to preventable causes, 18.4% by poorly defined causes and nearly one in three by external causes. Approximately one in four were due to traffic accidents, 41.9% by drowning and submersion. Also, there were significant frequencies of deaths associated with respiratory diseases (17.5%) and infectious and parasitic diseases (16.6%). Conclusion: These findings reinforce the importance of studies of infant mortality, drawing attention to the debate on policy design to reduce childhood deaths, especially in acting on preventable causes.

Reflexão sobre prevenção de acidentes à criança no âmbito doméstico

The aim was to reflect what action to prevent accidents used by caregivers / participants in the home. This is a prospecive cross-sectional descriptive study conducted at the Pediatric Inpatient Unit, Hospital of the Medical School of Botucatu – Unesp, during the months from May to August 2010.A questionnaire was used in the form of check list (Annex I) on measures to prevent accidents. The participant chose two alternatives taking into consideration the order of priority in the prevention of accidents. This study shows that for the age group from 29 days to 2 years, the companions chose these preventive measures for falls, burns, poisoning and drowning, “do not put near the windows mobile” (27.8%), “no access the match, lighter and appliances (22.2%), leave toxic substances out of reach and sight of children (41.7%) and empty buckets, tubs and pools after use (27.8% ). Regarding the age group 2-6 years, the measures for these types of accidents were not put near the windows mobile (26.5%), do not have access to matches, lighters and household appliances (20.9% ), leave toxic products out of reach and sight of children (27.9%) and maintain tanks, tanks and wells or struck with some protection (20.2%). For ages 6 to 10 years, the measures chosen to more such accidents were dry liquid spilled on the ground (23.5%), do not have access to matches, lighters and household appliances (22.5% ), leave toxic products out of reach and sight of children (31%) and keep tanks, tanks and wells or struck with some protection (23.5%). One fact that attracted our attention was that the preventive measures most frequently used by caregivers, regardless of age, show results that differ in few alternatives. It is essential to the understanding of the escorts / participants on the importance of injury prevention. Even today is predominantly defined as accident, injury must be addressed through measures

Ocorrência de evento climático extremo na cidade de Rio Claro-SP: episódio 24 e 25 de fevereiro de 2010

This work focuses on the analysis of extreme precipitation episode in the city of Rio Claro, held on 24 and 25 February 2010, which caused severe impacts to society, and a victim of drowning due to flooding due to flood in urban stream. Although the temporal concentration of summer rainfall is characteristic of tropical climatic regimes, each year there are issues of social and environmental impacts deflagrated by precipitation events in the city. These findings reinforce the importance of analyzing atmospheric conditions correlated to change in space usage
