ABSTRACT
The description of Amazophrynella minuta was published in 1941 by the Swedish naturalist Douglas Melin based on material from Taracuá (Amazonas state, Brazil). This description was very brief and based on the morphology of few specimens with diagnostic characters and color variation not well defined. Moreover, the type series is currently in poor state of conservation. Consequently, taxonomic ambiguity surrounds the nominal taxon A. minuta, which hampers the description of many unnamed congeneric species. Herein, we redescribe A. minuta based on recently collected specimens from the type locality, designate a lectotype, formulate a new diagnosis, provide patterns of morphological variation, measurements and body proportions.

Since nomenclature is intended to reflect the evolutionary history of organisms, advances in our understanding of historical relationships may lead to changes in classification, and thus potentially in taxonomic instability. An unstable nomenclature for medically important animals like venomous snakes is of concern, and its implications in venom/antivenom research and snakebite treatment have been extensively discussed since the 90´s. The taxonomy of the pitvipers of the Bothrops complex has been historically problematic and different genus-level rearrangements were proposed to rectify the long-standing paraphyly of the group. Here we review the toxinological literature on the Bothrops complex to estimate the impact of recent proposals of classification in non-systematic research. This assessment revealed moderate levels of nomenclatural instability in the last five years, and the recurrence of some practices discussed in previous studies regarding the use of classifications and the information provided about the origin of venom samples. We briefly comment on a few examples and the implications of different proposals of classifications for the Bothrops complex. The aim of this review is to contribute to the reduction of adverse effects of current taxonomic instability in a group of medical importance in the Americas.

Se describe Hadruroides bustamantei, una nueva especie de Caraboctoninae de los valles interandinos del centro del Perú (26003289 m). Esta especie está muy relacionado con H. mauryi Francke & Soleglad, con la cual fue confundida. La nueva especie difiere de H. mauryi, por la proporción largo /ancho de la pinza del pedipalpo y en el patrón de pigmentación de los tergitos, patas y segmentos caudales. Con la descripción de H. bustamentei, el número de especies conocidas en el género Hadruroides se eleva a diez.
Hadruroides bustamantei, a new caraboctonid species from inter Andean valleys of central Peru (26003289 m) is described. This species is most related to H. mauryi Francke & Soleglad, with which was confused. The new species differs from H. mauryi, by length/width ratio of the male chela and the pigmentation pattern of the tergites, legs and metasomal segments. With the description of H. bustamantei, the number of known species in the genus Hadruroides is elevated to ten.

Foi realizada reavaliaçäo clínica e radiológica de 92 pacientes somando um total de 111 casos de artroplastia total do quadril com utilizaçäo da prótese cimentada de Charnley, entre 1975 e 1985, no Serviço de Quadril do Hospital de Tráumato-Ortopedia Dr. Mßrio Jorge, com seguimento mínimo de dez anos. Um total de 60 por cento das próteses cimentadas estäo estáveis, sem sinais clínicos ou radiológicos de soltura. Foram encontradas evidências de afrouxamento nos outros 40 por cento, das quais 64 por cento foram do componente acetabular, 23 por cento do femural e 23 por cento em ambos os componentes. Esse percentual está de acordo com a estatística presente nos artigos de toda a literatura mundial, permanecendo a prótese cimentada de Charnley como uma grande alternativa para as artroplastias totais do quadril.

O escorregamento epifisário superior do fêmur (EESF), nos graus moderado e grave, altera a biomecânica do quadril. Por isso, os autores indicam a osteotomia tridimensional na prevençÒo da artrose precoce. Foram tratados 21 quadris por esse método, obtendo um índice de 73 por cento de bons resultados, levando-os a acreditar que, com o aumento da experiência, alcançaräo ainda maior sucesso com esse procedimento.

En este trabajo estandarizò la toma de muestra en sangre de cordòn de recièn nacidos por goteo en papel de filtro y se adecuo la tècnica de dosaje de TSH neonatal por el mètodo IRMA, en base a la producciòn local de estandaresw y trazadores, complementados con reactivos NETRIA. Se analizaron 2500 muestras del Centro de Salud N§ 5 y de la Maternidad del Hospital de Clìnicas. El rango de TSH neonatal (Confianza del 95 por ciento), es de 13.6 +/-15.7 microUI/ml, siendo el punto de corte de 30 microUI/ml

Os autores avaliam o comportamento de 59 próteses acetabulares rosqueadas do tipo Parhofer aplicadas em 54 pacientes, utilizando o método de avaliaçäo clínica de Merle d'Aubigné-Postel modificado por Charnley e a avaliaçäo radiológica de Callaghan. os resultados foram de 59,4 porcento de bons resultados e 40,6 porcento de resultados insatisfatórios
