Diagnosis and Customs Revealed by Peasants and Shepherds during the Transhumant Grazing of Pastoreña Goats in the Mixteca of Oaxaca, Mexico

Transhumant pastoralism is a livelihood for many smallholders in the world. In Mexico, transhumant pastoralism has been practiced for 500 years and is classified as a system of transhumant goat pastoralism (TGP). The focus of the study was to identify and characterize the main goat herders of transhumance in the Mixteca-Baja of Mexico. The investigation was carried out in two phases: The first included exploring the districts to locate, contact, and live with the people involved, 13 peasants named Patrones ranging from 40 to 76 years of age. The second phase investigated the transhumant routes and the zootechnical activities of the herds. They live in five locations with an inventory of 12 thousand goats known as Pastoreñas. The TGP is a primary economic activity for all the people, and La Matanza is the main economic activity consisting of the slaughter and marketing of goats. The study revealed that the activities depend on the type of economic unit. Transhumant Pastoreña goats garner the highest prices paid by merchants ranging from 47–70.4 USD per goat. In conclusion, the TGP is an interesting production system, and livestock activity has an essential ecological niche combining income generation and conservation of the environment

Oral and cutaneous lymphomas other than mycosis fungoides and sézary syndrome in a mexican cohort: Recategorization and evaluation of international geographical disparities

Background: Nonmycosis fungoides/Sézary syndrome (non-MF/SS) primary cutaneous lymphomas (PCL) are currently categorized under the 2005-World Health Organization/European Organization for Research and Treatment of Cancer (WHO-EORTC) classification for PCL. These differ in behavior from secondary cutaneous lymphomas (SCL) and to lymphomas limited to the oral cavity (primary oral lymphomas [POL]) both categorized under the 2016-WHO classification for lymphoid neoplasms. Aims: This study aims to report the first series of non-MF/SS PCL, SCL, and POL in a Mexican cohort, examine the applicability of current classification systems and compare our findings with those from foreign cohorts. Materials and Methods: Eighteen non-MF/SS PCL, four SCL, and two POL with available tissue for morphology and immunophenotypic assessment were reclassified according to the 2005-WHO/EORTC and 2016-WHO classifications. Results: Non-MF/SS PCLs were primarily of T-cell origin (61%) where CD30+ lymphoproliferative disorders predominated, followed by Epstein–Barr virus-induced lymphomas, and peripheral T-cell lymphomas, not otherwise specified. Primary cutaneous B-cell lymphomas (BCL) were primarily of follicle center cell origin followed by postgerminal lymphomas of the diffuse large BCL variety. Conclusions: Most non-MF/SS PCL, SCL, and POL can be adequately categorized according to the 2005-WHO/EORTC and 2016-WHO classification systems, even when dealing with clinically atypical cases. The relative frequencies in our cohort hold closer similarities to Asian registries than from those of Europe/USA, supporting the concept of individual and/or racial susceptibility, and the notion of geographical variances in the rate of lymphomas. In particular, such disparity may arise from viral-induced lymphomas which might show partial geographical restriction
