Continuous endoscopic manual suturing for colorectal anastomotic fistula closure.

A 54-year-old male underwent a low anterior resection in 2015 for rectal adenocarcinoma. He presented to the emergency department with a two-week history of fever, perianal pain, an erythematous, warm, and actively draining mass. Physical examination revealed a perianal abscess in the left posterior gluteal region, with a palpable internal fistulous orifice 3 cm from the anal margin.

Hybrid-APC treatment for gastric vascular ectasia of an atypical location after failed radiofrequency ablation.

A 76-year-old woman was being followed up for chronic anemia secondary to bleeding from vascular ectasias at the gastric antrum and the cardial and subcardial region. On several occasions the patient required fulguration of these lesions with conventional APC, which resulted in no clear improvement. Radiofrequency ablation of these lesions was then attempted using a 90-degree probe, which was successful on antral angiodysplasias but failed to remove lesions in the cardial and subcardial region since anatomy there prevented proper apposition of the probe onto the target mucosa.

Genotyping Toxoplasma gondii with the B1 Gene in Naturally Infected Sheep from an Endemic Region in the Pacific Coast of Mexico.

Toxoplasma gondii is a protozoan parasite with a broad ecological valence, which has been detected in a wide range of hosts and landscapes. Although the genus is considered monospecific, in recent years it has been demonstrated to exhibit more genetic variability than previously known. In Mexico, there are few genotyping studies, which suggest that classical, autochthonous, and atypical strains are circulating.

First isolation of Toxoplasma gondii from cats of Colima, Mexico: tissue distribution and genetic characterization.

Toxoplasma gondii is among the commonest zoonotic infectious agents worldwide. It infects many warm-blooded animals, including felines, the definitive hosts. This parasite is now classified in 15 haplogroups spread out around the world.
