Echinococcus granulosus cattle strain identification in an autochthonous case of cystic echinococcosis in central Mexico.

Echinococcosis is a frequent hepatic parasitic disease in several countries but it is practically absent in Mexico. A cattle strain of Echinococcus granulosus was identified by RAPD, PCR-RFLP and mitochondrial CO1 gene analysis in an autochthonous case. The parasite was obtained after a laparoscopic excision of a liver cyst from a patient that was symptomatic for 6 years but mis-diagnosed before hospitalization.

[Conversion to laparoscopic Roux-en-Y gastric bypass after vertical banded gastroplasty. A case report].

Background: Vertical banded gastroplasty (VBG) is sometimes associated with gastroesophageal reflux disease (GERD) and long-time failure in weight loss. This situation is a problem; one therapeutic option is a Roux-en-Y gastric bypass (RYGBP).

Objective: To analyze the perspective of laparoscopic surgical treatment in a patient with persistent GERD after traditional bariatric surgery for morbid obesity management.

[Identification and integral management of a case of autochthonous hydatidosis in Mexico].

Objective: To describe a case of hydatid disease in Mexico.

Background: Liver hydatid disease is the most frequent hepatic parasitic disease in developed countries and is considered practically absent in Mexico.

Methods: In this paper we report identification, clinical management, and epidemiologic parasitologic, and molecular biological studies of an autochthonous case of hydatid disease in Mexico.
