Effects of azoxystrobin, chlorothalonil, and ethoprophos on the reproduction of...
Leitão, Sara; Cerejeira, M. José; Van den Brink, Paul J.; Sousa, J. P.The potential terrestrial toxicity of three pesticides, azoxystrobin, chlorothalonil, and ethoprophos was evaluated using reproduction ecotoxicological tests with different non-target species: the collembolan Folsomia candida, the earthworm Eisenia andrei, and the enchytraeid Enchytraeus crypticus. All reproduction tests were performed with natural soil from a Mediterranean agricultural area (with no pesticide ...
Ethoprophos fate on soil–water interface and effects on non-target terrestrial ...
Leitão, Sara; Moreira-Santos, Matilde; Van den Brink, Paul J.; Ribeiro, R.; Cerejeira, M. José; Sousa, J. P.The present study aimed to assess the environmental fate of the insecticide and nematicide ethoprophos in the soil–water interface following the pesticide application in simulated maize and potato crops under Mediterranean agricultural conditions, particularly of irrigation. Focus was given to the soil–water transfer pathways (leaching and runoff), to the pesticide transport in soil between pesticide applicatio...
New improvements on pesticide ecological risk assessment on the soil-water inte...
Leitão, Sara Pais de Almeida da SilvaDoutoramento em Engenharia Agronómica - Instituto Superior de Agronomia ; Improving knowledge to evaluate and reduce pesticide impacts in the environment is a present concern to achieve their sustainable use. With the aim of increasing ecological relevance on the environmental risk assessment of pesticides (ERA), an integrated approach was undertaken linking pesticide fate and effects on aquatic and terrestria...
Lithokelyphopedion.
Gonçalves, Carla; Pimentel, Ana; Leitão, Sara; Santos, Rui M; Costa, J NascimentoLithopedions are extremely rare conditions. Less than 300 cases were described worldwide. We report a case occurring in a woman of 77 years of age, admitted with dehydration, urinary tract infection and infected limb pressure ulcers. She had been recently admitted in a Surgery ward for incarcerated umbilical hernia. At the time the abdominal examination revealed a mass with about 10 cm in diameter, with petrous...
Undifferentiated osteoclastic-type giant cell carcinoma.
Pimentel, Ana; Leitão, Sara; Dias, Nuno; Cipriano, Maria Augusta; Leite, Júlio; Santos, Rui Marques; Nascimento Costa, J MInitially described 40 years ago (Rosai), the undifferentiated osteoclastic-type giant cell carcinoma (IOGCC) is a variant of ductal adenocarcinoma and accounts for less than 1% of exocrine pancreatic tumors. Its extreme rarity, with consequent existence of few reports and clinical experience, leads to the arousal of doubts with regard to its histogenesis, types of approach and therapeutical attitudes. It is im...

Lebre, Rosário; Ruiz, Victor; Leitão, Sara; Santos, Arsénio; Santos, Rui; Porto, ArmandoA intoxicação aguda pelo sulfato de cobre é rara e frequente- mente acidental. Manifesta-se por náuseas, vómitos, diarreia, anemia hemolítica e, nos casos mais graves, insufi ciência renal, insufi ciência hepática e coma. Os autores descrevem um caso clínico de intoxicação voluntária por sulfato de cobre, cujas principais manifestações clínicas foram náuseas, vómitos esverdeados, diarreia, hipotensão, icterícia...
Acute myelogenous leukemia presenting as diabetes insipidus.
Calretas, Susana; Leitão, Sara; Cortesão, Emília; Espadana, Ana Isabel; Santos, Rui M; Porto, ArmandoCentral diabetes insipidus, is a syndrome characterized by the excretion of abnormally elevated volumes of diluted urine, due to the diminution of reabsorption of water in the collecting ducts, induced by the diminution of production of antidiuretic hormone. The involvement of the central nervous system in the leukaemia is frequent, but the association leukaemia/diabetes insipidus is rare. We describe a clinica...
Doença de Castleman
Leitão, Sara; Santos, Rui; Jesus, Emanuel; Santos, Arsénio; Crespo, Jorge; Martins, Yvette; Costa, Nascimento; Lopes, David; Simões, ArmindoApresentam-se dois casos clínicos de doença de Castleman, situação rara e de difícil diagnóstico, um na forma multissistémica e outro na forma localizada, um na variante plasmocitária e outro na de tipo misto. Nos dois casos, o diagnóstico só foi possível por exame histológico. Salienta-se a grande variabilidade na sintomatologia e prognóstico, de acordo com a variante histológica e a forma de apresentação. ; ...
