First record of mating behaviour and induced parturition of the Brazilian endemic Lutz's stingray Hypanus berthalutzae.

The recently described Lutz's stingray Hypanus berthalutzae is endemic to the Brazilian Province, including oceanic islands. Although it is expected to have life-history traits similar to the southern stingray H. americanus, little is known about its reproductive biology. Here we present the first observations of courtship behaviour (n = 4), copulation (n = 3) and an induced parturition of H. berthalutzae at the Fernando de Noronha Archipelago, an insular Marine Protected Area from the Equatorial Atlantic Ocean. The mating event records included (1) 'chasing/close following', (2) 'biting/precopulatory biting', (3) 'insertion/copulation' and (4) 'separation'. These results are especially relevant considering that records of reproductive behaviour in the wild are rare for elasmobranchs in general. Mating events occurred in different months, suggesting that the reproductive cycle of H. berthalutzae in this insular system is asynchronous, as observed for other stingray species in regions with favourable environmental conditions and abundant food throughout the year. The opportunistic documentation of the induced parturition allowed for direct nonlethal observation of the two pups at or near full term in late May. Although preliminary, these observations should be considered in future management plans as they provide relevant data about the life-history traits and mating behaviour of this endemic and threatened species.

Tratamento endovascular de angiomiolipoma renal por embolização arterial seletiva / Endovascular treatment of renal angiomiolipoma by selective arterial embolization

Relata-se um caso de um paciente com queixa principal de dor lombar à esquerda, portador de angiomiolipomas renais (AMLRs) bilaterais, com a lesão mais volumosa de 6,2 cm em seu maior diâmetro, submetido a tratamento endovascular por embolização arterial superseletiva com microesferas. Os AMLRs são tumores benignos raros. A maioria é esporádica, enquanto uma minoria está associada à Esclerose Tuberosa Complexa (ETC). Os AMLRs maiores do que 4 cm devem ser tratados devido ao maior risco de complicações, principalmente hemorrágicas. A embolização arterial seletiva (EAS) é um tratamento efetivo e seguro para os AMLRs.

We report a case of a patient with a major complaint of left lumbar pain, diagnosed with bilateral renal angiomyolipomas (AMLRs), with the most voluminous lesion of 6.2 cm in its largest diameter, underwent endovascular superselective arterial embolization with microspheres. The AMLRs are rare benign tumors. Most are sporadic, while a minority is associated with Tuberous Sclerosis Complex (ETC). The AMLRs larger than 4 cm must be treated due to higher risk of complications, especially hemorrhagic. A selective arterial embolization (EAS) is an effective and safe treatment for AMLRs.

Aspectos clínicos da doença Trofoblástica gestacional / Clinical aspects of gestacional trophoblastic disease

Objetivo: analisar os aspectos clínicos e diagnósticos das pacientes com suspeitaultrassonográfica de Doença Trofoblástica Gestacional(DTG). Método: estudo observacional etransversal, analisados 159 prontuários de pacientes acompanhadas no Ambulatório de Mola daFundação Hospital Santa Casa de Misericórdia do Pará, entre junho de 2010 a junho de 2011.Resultados: a maioria das pacientes tinha idade entre 16 e 34 anos, idade gestacional menorque 20 semanas e oriundas do interior do Pará. A principal manifestação clínica foi sangramentovaginal e anemia estava presente em 63,28% dos casos. Do grupo pesquisado, 86,3%apresentaram concordância entre a impressão diagnóstica ultrassonográfica de DTG e ohistopatológico. Conclusão: apesar do exame ultrassonográfico ser de alta sensibilidade para odiagnóstico de DTG, muitos são os casos erroneamente diagnosticados como aborto ou gestaçãoanembrionada, devido a maior incidência dessas afecções, o que faz do histopatológico umexame imprescindível para a confirmação diagnóstica.

Objective: analyse the clinical and diagnostic aspects of patients with ultrasound suspected ofgestational trophoblastic disease. Methods: observational and transversal research, wheremedical records of 159 patients followed at Fundação Hospital Santa Casa de Misericordia doPará ambulatory were analyzed from June 2010 and June 2011. Results: It was observed thatmost of them were aged between 16 and 34 years, didn?t realized prenatal care, gestational ageat diagnosis was less than 20 weeks and came from the interior of Pará The main clinicalmanifestation was vaginal bleeding and anemia was present in 63,28% of them. In the groupstudied, 86.3% showed agreement between ultrasound diagnostic impression for gestationaltrophoblastic disease and histopathology. Conclusion: Although the ultrasound is highlysensitive to diagnosis this desease, many cases are misdiagnosed as abortion or anembryonicpregnancy because of the higher incidence of these issues. That makes essential thehistopathological to confirm the diagnosis

Endovascular treatment of giant splenic artery aneurysm.

Introduction. Visceral artery aneurysms are uncommon. Among them, splenic artery is the most common (46-60%). Most splenic artery aneurysms are asymptomatic and diagnosed incidentally, but its rupture, potentially fatal, occurs in up to 8% of cases. Presentation of Case. A female patient, 64 years old, diagnosed with a giant aneurysm of the splenic artery (approximately 6.5 cm in diameter) was successfully submitted to endovascular treatment by stent graft implantation. Discussion. Symptomatic aneurysms and those larger than 2 cm represent some of the main indications for intervention. The treatment may be by laparotomy, laparoscopy, or endovascular techniques. Among the various endovascular methods discussed in this paper, there is stent graft implantation, a method still few reported in the literature. Conclusion. Although some authors still consider the endovascular approach as an exception to the treatment of SAA, in major specialized centers these techniques have been consolidated as the preferred choice, reserving the surgical approach in cases where this cannot be used. For being a less aggressive approach, it offers an opportunity of treatment to patients considered "high risk" for surgical treatment by laparotomy/laparoscopy.

Valores relativos ao trabalho como antecedentes do comprometimento organizacional

O objetivo central desta dissertação foi estudar os valores relativos ao trabalho como antecedentes ao comprometimento organizacional. O comprometimento foi abordado em suas três dimensões afetiva, normativa e calculativa. Para tanto, utilizou-se como instrumento de coleta de dados um questionário composto pela Escala de Valores Relativos ao Trabalho – EVT, Escala do Comprometimento Organizacional Afetivo – ECOA, Escala do Comprometimento Organizacional Normativo – ECON e Escala do Comprometimento Organizacional Calculativo – ECOC. O questionário foi aplicado a 183 funcionários de uma instituição financeira de Brasília. Os resultados indicaram uma influência de prestígio e de estabilidade (valores relativos ao trabalho) no comprometimento organizacional, vale ressaltar que o resultado referente à estabilidade foi negativo. Este estudo não contemplou a análise da relação entre os valores relativos ao trabalho e o desenvolvimento do comprometimento organizacional, devendo ser objeto de pesquisas futuras com amostras mais significativas, a fim de reforçar os achados deste trabalho.(AU)

The central purpose of this research was to study the influence of work values in the organization commitment. The commitment was boarded in its three dimensions affective, normative and calculative. For that, it was used as instrument of collection of data, a composed questionnaire with Work Values Scale, Scale of the Commitment Affective Organization, Scale of the Commitment Normative Organization and Scale of the Commitment Organization Calculative. The questionnaire was applied to 183 employees of a financial institution of Brasilia. The results had indicated the influence of prestige and stability (work values) in the organization commitment. It is worth to say that the relation with stability was negative. This study did not contemplate the relation between the work values and the development of the organization commitment, which must be object of future research with samples more significant, in order to support the findings of this work.(AU)
