  A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala Abstract  A new species of the spider genus Euagrus Ausserer, 1875 from temperate pine-oak forests in the states of Tlaxcala and Hidalgo, Mexico is described: E. pulque sp. nov. The description of the new species is based on male and female adult specimens. Additionally, Euagrus gus Coyle, 1988 is recorded for the very first time in the state of Tlaxcala. These species have sympatric distributions in La Malinche National Park, Tlaxcala. With this description, the diversity of the genus increases to 23 species, with Mexico harboring the highest diversity with 17 described species.  Valdez-Mondragón, A., Salinas-Velasco, H.

Scorpionism in children and adolescents: clinical and epidemiological factors associated with severe cases

Summary

Objective: To analyze the association between epidemiological and clinical factors and the severity of scorpion accidents in children and adolescents. Methods: This is a retrospective quantitative cross-sectional study that analyzed 648 medical records of patients aged zero to twelve. The outcome variable was the severity of scorpionism, with bivariate analyzes (Pearson's Chi-Square test) and Poisson multivariate analyzes to identify associated factors. Results: It was evident that 34.7% of cases were serious, predominantly in female children, under three years of age, non-white, urban and from Montes Claros. Most accidents occurred before 5pm, in the lower limbs, with care after 1am. After-effects (RP=1.75; 95%CI 1.00-3.05) and UTI (RP=2.45 95%CI 1.23-4.88) were associated with severity, while bites in the lower limbs reduced the prevalence of serious accidents (RP= 0.76; IC95 0.6-2.94). Conclusion: The epidemiological profile indicated that the majority of bites occurred before 5 pm, with care after 1 hour, and bites in the lower limbs were associated with a lower prevalence. The clinical profile was related to ICU admission and the use of vasoactive amines. Given the importance of scorpionism in children, it is crucial to educate the population to prevent accidents and improve the prognosis.
