Brote de "pie de festuca" en un rodeo de cría de Salta, Argentina / Outbreak of fescue foot in a livestock in Salta, Argentina

Festuca arundinacea es una gramínea perenne de uso forrajero muy difundida mundialmente. Aquí se describe un brote de “pie de festuca” en el Noroeste Argentino que afectó a un rodeo de cría con una incidencia del 5%. Los signos clínicos fueron claudicación, edema en los miembros, gangrena en las extremidades y exungulación. La pastura donde los animales permanecían correspondía a un lote naturalizado de festuca siendo el nivel de infestación con Neotyphodium coenophialum del 71%. El cuadro de pie de festuca es muy conocido pero poco informado en Argentina. En el brote el diagnostico se confirmó por los antecedentes clínicos y epidemiológicos sumado al elevado grado de infestación del hongo en la pastura. La toxicidad de la festuca es un problema mundialmente distribuido y en Argentina ha sido más estudiado en la región centro del país. Los antecedentes de toxicidad de esta especie son escasos y aislados en el Noroeste Argentino.

Beef cattle herd were affected and the incidence was 5%. The clinical signs were claudication, edema in the limbs, gangrene in the extremities and exungulation. The grazing areas where the animals remained corresponded to a natural batch of fescue. Neotyphodium coenophialum infestation level was 71%.

In the outbreak presented here diagnosis was confirmed by the clinical and epidemiological antecedents as well as the high level of infestation of the pasture.

Scarce information is available regarding the toxicity of this species for northwestern Argentina.

Forensic Consideration of Postpartum Acute Myocardial Infarction Associated with Ergot Derivatives Administration in Old Aged Woman: A Case Report / 대한법의학회지

Cases of acute myocardial infarction (AMI) that occurs during pregnancy or postpartum are rarely reported. Ergot derivatives were known to induce spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI even in normal healthy people. Several cases are also reported that ergot derivatives may trigger severe AMI in postpartum period. Here, we report a case of a forty-year-old pregnant woman who was succeeded to be pregnant by artificial fertilization died after treatment with ergot derivatives. Examinations of autopsy have revealed AMI with severe coronary atherosclerosis. This case is the first report which shows aggravation of preexistent severe coronary atherosclerosis after postpartum infusion of ergot derivatives.

An Autopsy Case of Postpartum Acute Myocardial Infarction Associated with Postpartum Ergot Alkaloids Administration in Old-Aged Pregnant Women

Cases of acute myocardial infarction (AMI) that occur during pregnancy or postpartum are rarely reported. Ergot derivatives are known to induce the spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI, even in normal healthy people. In several reported cases, ergot derivatives triggered severe AMI during the postpartum period. Here, we report the case of a forty-year-old woman who was successfully impregnated by artificial fertilization and died after treatment with ergot derivatives. The autopsy revealed AMI with severe coronary atherosclerosis. This is the first case that reports aggravation of pre-existent severe coronary atherosclerosis after postpartum infusion of ergot derivtives.
