RESUMO

We present a review of Scatimus Erichson (Coleoptera: Scarabaeidae: Scarabaeinae: Ateuchini: Scatimina) in Colombia, with the description of S. strenua new species from the Central Andes (Antioquia Department). Records of S. strandi Balthasar from southwestern Colombia (Caquetá and Nariño Departments) are validated. The distributions of S. ovatus Harold from the Magdalena, Chocó-Darién, and Sierra Nevada de Santa Marta provinces and S. fernandezi Martínez in the eastern foothills of the Eastern Cordillera (Orinoco-Amazon) are confirmed. New departmental records and distribution maps for Colombia are presented; an updated key for the taxonomic identification of Scatimus is included. With a total of four species, Colombia has the second highest Scatimus species richness of any country.

RESUMO

ABSTRACT. Introduction: the cusp pattern and the deflecting wrinkle are two morphological traits whose expression and variability contribute to the morphological configuration of the occlusal surface of deciduous and permanent lower molar teeth. The objective of the present study was to estimate the correlation between cusp pattern and deflecting wrinkle in six ethnic groups from southwestern Colombia. Methods: analysis of 480 plaster models corresponding to 100 mixed Caucasoid mestizos from Cali (50 men and 50 women), 60 Afro-descendants from Cali (34 women and 26 men), 84 Afro-descendants from Puerto Tejada (42 women and 42 men), 116 Afro-descendants from Villa Rica (57 men and 59 women), 60 misak indigenous (37 women and 23 men) and 60 nasa indigenous (35 women and 25 men). Results: there were high frequencies (over 60%) of cusp pattern (Y expression) and deflecting wrinkle (grades 2 and 3) in deciduous first lower molars, mid frequencies (between 40 and 59%) of cusp pattern (Y and + expressions) and deflecting wrinkle (grades 1 and 2) in permanent first lower molars, and mid frequencies (between 40 and 59%) of cusp pattern (+ and X expressions) and deflecting wrinkle (grades 1 and 2) in permanent lower second molars. Conclusions: these frequencies suggest a trend in cusp pattern, which may vary according to the degree of expression of the deflecting wrinkle. This tendency consists of the Y cusp pattern when the deflecting wrinkle is expressed in grades 2 and 3. Bilaterally was observed and there was no sexual dimorphism.

RESUMEN. Introducción: el patrón cuspídeo y el pliegue acodado son dos rasgos morfológicos cuya expresión y variabilidad contribuyen con la configuración morfológica de la superficie oclusal de los dientes molares inferiores temporales y permanentes. El objetivo del presente estudio consistió en estimar la correlación entre el patrón cuspídeo y el pliegue acodado en seis grupos étnicos del suroccidente colombiano. Métodos: se observaron 480 modelos de yeso correspondientes a 100 mestizos caucasoides de Cali (50 mujeres y 50 hombres), 60 afrodescendientes de Cali (34 mujeres y 26 hombres), 84 afrodescendientes de Puerto Tejada (42 mujeres y 42 hombres), 116 afrodescendientes de Villa Rica (59 mujeres y 57 hombres), 60 indígenas misak (37 mujeres y 23 hombres) y 60 indígenas nasa (35 mujeres y 25 hombres). Resultados: se presentaron frecuencias altas (mayores al 60%) de patrón cuspídeo (expresión Y) y pliegue acodado (grados 2 y 3) de los primeros molares inferiores temporales, frecuencias medias (entre 40 y 59%) de patrón cuspídeo (expresiones Y y +) y pliegue acodado (grados 1 y 2) de los primeros molares inferiores permanentes, y frecuencias medias (entre 40 y 59%) de patrón cuspídeo (expresiones + y X) y pliegue acodado (grados 1 y 2) de los segundos molares inferiores permanentes. Conclusiones: con base en dichas frecuencias, se observó una tendencia en la configuración del patrón cuspídeo, el cual puede variar de acuerdo al grado de expresión del pliegue acodado; dicha tendencia consiste en el patrón cuspídeo Y cuando el pliegue acodado se expresa en los grados 2 y 3. Se observó bilateralidad y no hubo dimorfismo sexual.

RESUMO

BACKGROUND: Trauma is an important cause of morbidity and mortality in children. Blunt trauma is the most common type and falls and road traffic injuries (RTI) are the most frequent mechanisms. METHODS: Secondary analysis of institutional data included within the Panamerican Society of Trauma Registry (STP-ITSDP). A total of 581 trauma patients younger than 18years, hospitalized between 2012 and 2014, were included. RESULTS: Blunt trauma (BT) (68%) was the most common type, and falls (42.5%) the most common mechanism. Median age was: 14years for penetrating trauma (PT), 8years for BT, and 5.5years for other types of trauma (OT). Of all patients, 8.1% had a Glasgow score<8, 9% had a Glasgow score of 8-13 and 81.1% had a Glasgow score higher than 14. Death occurred in 5.2% of patients: 83.3% as inpatients and 16.7% during initial management in the emergency room (ER). Patients dying in the ER were mostly PT victims, with higher ISS and lower Glasgow scores. CONCLUSIONS: Trauma is an important cause of morbidity and mortality in our pediatric population. Fundación Valle de Lili (FVL), a referral hospital, receives a high number of trauma patients from southwestern Colombia. Detailed knowledge of epidemiological data will help us to develop rapid response strategies for patients with trauma and to develop prevention and promotion programs.

RESUMO

We confirm the presence of the bat Nyctinomops laticaudatus in southwestern Colombia, by the record of a colony of the species in the urban area of the town of Cartago municipality, Valle del Cauca department, at a 950 m elevation. This new record supports the distribution of the species in the geographic valley of the Cauca River and in southwestern Colombia, where it was previously regarded as hypothetical.
