A case report of Chagas disease in acute phase diagnosed by xenodiagnosis.

Chagas disease is a serious problem of parasitic disease in the American continent, this zoonosis is caused by the flagellated protozoan known as Trypanosoma cruzi and transmitted through trypomastigotes present in the blood of sick hosts or in the faeces of the triatomines. Metacyclic trypomastigotes were detected in the faeca material of Triatoma pallidepennis maintained in the laboratory after the xenodiagnosis study performed on a patient with suspected Chagas disease, which allowed to administer treatment in a timely manner in the acute phase of this disease.

The Role of Platelets in Ischemic Conditioning.

Ischemic heart disease (IHD) is one of the leading causes of death and disability worldwide. Platelets, as the main regulators of hemostasis, are major players in acute myocardial ischemia/reperfusion injury (IRI). Additionally, platelets are modified by endogenous cardioprotective strategies such as ischemic preconditioning, postconditioning, and remote ischemic conditioning.

Meeting report from the 2nd International Symposium on New Frontiers in Cardiovascular Research. Protecting the cardiovascular system from ischemia: between bench and bedside.

Recent advances in basic cardiovascular research as well as their translation into the clinical situation were the focus at the last "New Frontiers in Cardiovascular Research meeting". Major topics included the characterization of new targets and procedures in cardioprotection, deciphering new players and inflammatory mechanisms in ischemic heart disease as well as uncovering microRNAs and other biomarkers as versatile and possibly causal factors in cardiovascular pathogenesis. Although a number of pathological situations such as ischemia-reperfusion injury or atherosclerosis can be simulated and manipulated in diverse animal models, also to challenge new drugs for intervention, patient studies are the ultimate litmus test to obtain unequivocal information about the validity of biomedical concepts and their application in the clinics.

Cyclospora cayetanensis: this emerging protozoan pathogen in Mexico.

A Mexican airline pilot had clinical manifestations of illness after a five-day stay in Lima, Peru. Six months later in Mexico, he was given a diagnosis of infection with Cyclospora cayetanensis by using coproparasitoscopic serial tests. He was treated twice with nitazoxadine successfully.

Disseminated sporotrichosis.

Sporotrichosis is a subacute or chronic infection caused by Sporothrix schenckii. It is a primary cutaneous infection and it has different clinical forms: disseminated by lymphatic vessels (75%), localised cutaneous form (20%), disseminated cutaneous and extracuteus rarely. The systemic disseminated sporotrichosis is considered a severe opportunistic infection.

Cryptosporidiosis and other intestinal protozoan infections in children less than one year of age in Mexico City.

Parasitic diseases are very important in Mexico because of their economic impact and adverse effects on normal growth in children. Cryptosporidiosis has been associated with acute diarrhea in immune competent and incompetent human hosts, fecal contamination of drinking water sources, and handling of animals. Due to the lack of reports on cryptosporidiosis in Mexico, we conducted a parasitologic study in children with diarrhea and other clinical symptoms.
