Falling incidence of amputations for peripheral occlusive arterial disease in western Australia between 1980 and 1992

Objectives: To assess temporal trends in the incidence of surgical procedures for peripheral occlusive arterial disease (POAD) and associated changes in outcome as measured by the rate of major lower limb amputations for POAD. Design: a retrospective descriptive population-based study was conducted of the geographically isolated population of Western Austrialia between 1980 and 1992. Methods: Vascular procedures with an accompanying diagnosis of POAD were identified in a computerised system of name-identified records of all discharges from hospital for the population. These procedures were detected using relevant codes from the International Classification of Disease and Procedures. Records of angioplasty and thrombolysis procedures were augmented by searches of hospital-based registers of invasive radiological procedures. The data for the remaining procedures were validated by a review of a random sample of medical records. Results: over the 13 years of the study, rates of major amputations fell significantly for in non-amputation vascular surgery for individuals under the age of 60. In addition, rather than an overall rise in surgery there was shift away from sympathectomy and thromboendarterectomy to angioplasty and bypass surgery. Furthermore, an increasing proportion of all major amputations had a prior attempt at arterial reconstruction. Conclusion: These observations suggest the decrease in major amputations for POAD may reflect a fall in the incidence of POAD, possibly aided by move effective surgery, rather than increased rates of vascular surgery.

Weketrema gen.n., a new genus for Weketrema hawaiiense (Yamaguti, 1970) comb. n. (Digenea : Lecithasteridae) recently found in Australian marine fishes

A new genus, Weketrema, is erected in the family Lecithasteridae for the species hitherto known as Lecithophyllum hawniiense. Weket, ema hawaiiense (Yamaguti, 1970) comb, n. is redescribed from Scolopsis bilineatus (Bloch) (Perciformes: Nemipteridae) from Lizard Island and Heron Island, Queensland, Plectorhinchus gibbosus (Lacepede) (Perciformes: Haemulidae) from Heron Island and Cheilodactylus nigripes Richardson (Perciformes: Cheilodactylidae) and Latridopsis forsteri (Castelnau) (Perciformes: Latridae) from Stanley, northern Tasmania. The new genus is distinguished from related members of the family Lecithasteridae by its complete lack of a sinus-sac. Although placed in the subfamily Lecithasterinae pro tem, its true subfamily position is not entirely clear. Comment is made on its unusual distribution, both in terms of zoogeography and hosts.

The upper Paleozoic miospore genus Spelaeotriletes Neves and Owens, 1966, and constituent Gondwanan species

The upper Paleozoic miospore genus Spelaeotriletes Neves and Owens, 1966 is reviewed as a morpho-taxonomic entity and vis-a-vis other similarly constructed (pseudosaccate) genera - Geminospora Balme, 1962, Grandispora Hoffmeister, Staplin, and Malloy, 1955, Rhabdosporites Richardson, 1960, and Retispora Staplin, 1960. Detailed studies of numerous, mainly topotype specimens of Spelaeotriletes ybertii (Marques-Toigo, 1970) Playford and Powis, 1979 from the Lower Permian of Uruguay result in its re-diagnosis, in conjunction with a survey of its exclusively Gondwanan occurrences, particularly in South American strata extending from the Upper Carboniferous (Westphalian) into the Lower Permian, and also in Australian strata of approximately equivalent age. The characteristics of other species of Spelaeotriletes reported from upper Paleozoic deposits of Gondwana are discussed, as are their temporal representations in various broad regions of the supercontinent (South America, North Africa, Australia). These species include two, perhaps three, that, like Spelaeotriletes triangulus/arenaceus, are known also from Euramerica - S. balteatus (Playford, 1963) Higgs, 1996, S. pretiosus (Playford, 1964) Utting, 1987, and possibly S. owensii Loboziak and Alpern, 1978. Other species, such as S. benghaziensis Loboziak and Clayton, 1988, S. giganteus Loboziak and Clayton, 1988, and S. vibrissus Playford and Satterthwait, 1988, have, on present knowledge, exclusively Gondwanan occurrences. S. queenslandensis Jones and Truswell. 1992, known only from Upper Carboniferous strata of northeastern Australia, is formally reassigned on sculptural grounds to Grandispora. Not unexpectedly in a paleogeographic perspective, North Africa and South America are more closely allied with each other than with Australia in terms of shared species of Spelaeotriletes.

Advances in neurotrauma in Australia 1970-2000

The management of neurotrauma in Australia has been one of the significant public health triumphs during the last 30 years of the 20th century. State and national government agencies act in a coordinated fashion to collect data and to promote research on how to manage neurotrauma patients. Between 1970 and 1995, fatalities from road accidents decreased by 47%. Hospital admissions have decreased by 40% despite a 40% increase in the population and a 120% increase in registered vehicles. Fatalities per 10,000 registered vehicles were 8.05% in 1970 and they fell to 1.84% per vehicles in 1995, while fatalities per 10;000 population were 3 in 1970 falling to 1.11 in 1995. Hospitalization from road crashes decreased 23% between March 1988 and March 1997. Public education has steadily improved, backed by the state public health sources. A uniform code of road safety laws has been adopted, backed by legislation and legal penalties and increasing police enforcement. Clinical care of patients has improved as a result of faster communications, tele-medicine, trauma systems, the CT scanner; intensive care units, and improved monitoring. Patient rehabilitation and counseling are now carried out at units accredited by the Australian Council on Health Care Standards.

New species of Opechona Looss, 1907 and Cephalolepidapedon Yamaguti, 1970 (Digenea: Lepocreadiidae) from fishes off northern Tasmania

Two new species of lepocreadiid trematodes are described from teleost fishes from off the coast of northern Tasmania. Opechona kahawai sp. nov. from Arripis sp. (Arripidae) differs from congeners by a combination of a longer prepharynx, longer excretory vesicle and the genital pore antero-sinistral to the ventral sucker. Cephalolepidapedon warehou sp. nov. from Seriolella punctata (Centrolophidae) differs from its only congener in the vitellarium reaching into the posterior forebody, a heavy concentration of eye-spot pigment in the forebody, a relatively narrower and more elongate body, a longer prepharynx and a more distinct oesophagus.

A curva de Phillips no Brasil e a política de metas de inflação : uma análise da evolução do trade-off durante o período 1980-2010

Diante de uma discussão não consensual a respeito da existência ou não de um trade-off entre inflação e desemprego (curva de Phillips), esta dissertação analisa a evolução desta relação na economia brasileira no período 1980-2010 através de duas análises diferentes: A primeira é uma análise considerada estática, realizada com a utilização de uma regressão linear simples. A segunda consiste em uma análise dinâmica, onde é utilizada uma regressão com coeficientes time-varying, com a estimação dos coeficientes sendo realizada com a aplicação do filtro de Kalman. Os resultados econométricos mostraram que a relação entre inflação e desemprego de fato se alterou ao longo do período analisado: A curva de Phillips se torna horizontal após o Plano Real e fica levemente positiva após o Regime de Metas de Inflação. Sendo assim, este trabalho basicamente se divide em duas partes: A primeira consiste de uma contextualização teórica da relação entre inflação e desemprego e do regime de metas de inflação. A segunda parte traz a análise econométrica, onde é descrita a evolução do trade-off. Diante dos resultados encontrados, são apresentadas suas possíveis causas e é realizada uma análise qualitativa da atual política monetária praticada pelo Banco Central do Brasil.
