Introduction. Recent studies carried out in the permanent dentition revealed a wide range of terminal relationships between enamel and cement described by Choquet, characterized by not having a unique pattern around the tooth neck. This is little studied in the primary dentition. Objective. To know the frequency distribution of the cemento-enamel junction in the temporary dental organs. Methodology. In a study approved by the Research and Ethics Commission of the Faculty of Stomatology of the BUAP (registration 2019104) a probabilistic, non-random sample, stratified by sex, of 73 healthy dental organs was analyzed, with more than one third of root and any dental formula of children between three and five years of age. They were observed under an optical microscope at magnifications of 5, 10 and 20x, slices obtained with the wear technique. Microphotographs obtained with a camera integrated to the microscope were analyzed by an observer (k = .9102). Results. 180 sections were obtained from the calculated sample. The percentage distribution of the cases corresponds case 1, 41%; case 2 present in 13%; case 3, 38%; and case 4, eight percent. According to the anatomic faces, case 1 was more frequent in the mesio-vestibular face (37%), case 2 in the mesio-lingual/palatal (44%), case 3 in 35% of the mesio-vestibular faces, and case 4 in 72% of the mesio-vestibular faces. Discussion. The tissue relations between the enamel and cement of the temporary dentition present the four combinations reported by Choquet in a different frequency distribution with respect to the authors consulted. Interdigitations between cementum and enamel of the primary dentition were observed, as well as serendipiti; some sui generis characteristics in the underlying dentin. [ABSTRACT FROM AUTHOR]

Introduction. Little literature has been reported about the forms that characterize caries lesions according to their destructive advancement of dental tissues, so it is necessary to describe the characteristics of the lesions in each of the stages of advancement and match them with the observations clinics, in such a way that the radiographic image is complemented, because the latter has serious limitations in incipient lesions. Objective. Describe the characteristics of caries lesions according to the progress of the destructive process of dental hard tissues. Methodology. In a descriptive, observational, cross-sectional, prospective, heterodemic and single-center study, a sample of 30 specimens of donated temporary dental organs, preserved in formalin and cut at 1 mm thickness was analyzed to be observed under different types of microscope to describe the variables: caries lesion shape, penetration, color and characteristics of the lesions surface at each stage of advancement; according to the independent variable ICDAS caries diagnostic code. Results. The ICDAS 0 code does not present tissue alterations. ICDAS 1 presents superficial erosion; ICDAS 2 all enamel affected with loss of dentin tufts, has a cylindrical shape, dull white color; ICDAS 3 all demineralized enamel, cylindrical shape, greyish white; ICDAS 4 undermined enamel without dentin support with affected dentin tubules; ICDAS 5 total enamel loss; 40% affects deep dentin, brown conical shape; ICDAS 6 total destruction of enamel, totally affected dentin, 40% black color. Conclusions. Histological images complement the clinical appearance of caries lesions according to their progress. [ABSTRACT FROM AUTHOR]

Introduction. It is considered that in the temporomandibular joint of children, the glenoid cavity is almost flat with a low prominence of the anterior or temporal condyle that allows the anterior displacement of the jaw, so that the incisors cross over is smaller and it is considered that there is no Spee curve, and its analysis is lacking. Objective. To analyze the frequency and risk association of the presence of the Spee curve in each of the terminal planes and the overbite. Material and method. In a cross-sectional, prospective and analytical clinical epidemiological study, a heterodemic and multicentric probabilistic sample stratified by sex was analyzed, from 140 sets of temporary dentition models of the child population aged 3 to 5 years, without loss of proximal walls or cavitations for caries, as well as with fractured dental organs. Were analyzed the dependent variables Spee curve, terminal plane and overbite. Results. Were tested the hypothesis of dependence of the Spee curve with respect to the type of terminal plane (c2 = 7.104, p = 0.01, Gl = 1). The prevalence rate of the presence of the Spee curve was 43.47%. Its association with the straight terminal plane is RM = 3.96 and with the deep bite it is RM = 2.89. Conclusions. The curve of Spee is present in the deciduous dentition and responds to the need to compensate the condylar trajectory that promotes the maximum intercuspidization that allows protrusive de-occlusion thanks to the anterior and condylar guides that avoid excessive pressure in the posterior area, optimizes the incisive function during the cutting action and promotes the wear of cusps and incisal edges, which is why deep bites were not found.

Hydropower development causes modifications in hydrological patterns in rivers, altering aquatic ecosystems and the activities that are typically carried out there. To avoid direct alterations to rivers, it is necessary to maintain a minimum flow (ecological flow); however, it is also necessary to minimize effects on the natural functioning of the river, its ecosystem services and the activities that are engaged in there. The environmental flow, which incorporates morphological and human-use aspects, is defined based on this foundation. In this study, the environmental flow for a section of the Ñuble River is analysed and calculated, not only considering aspects such as hydrology and biota, but also including human activities that have traditionally taken place there (rafting and kayaking). SEA (2016) was used to calculate the environmental flow regime. Ecological and human components were analysed with CASIMIR software using information published in the SEA and obtained through interviews with river users. As a result, it was found that by following only the recommendations of SEA (2016), activities traditionally carried out in the river (tourism) will be altered. In addition, if the need for flows for tourism is included and quantified, the environmental flow should be greater than the flow estimated considering only regulations regarding hydrology and the functioning of the ichthyofauna present in the river.

The perioperative management of patients undergoing abdominal surgery has been based on traditional concepts and often not supported by scientific evidence. Recently there have been several scientific studies showing that some traditional procedures for the perioperative management of patients as preoperative fasting, bowel preparation, use of naso-gastric tubes, placement of intra-abdominal drainage, postoperative fasting etc. They are unnecessary and sometimes counterproductive. Perioperative management protocols ERAS or Fast-Track (Enhanced Recovery After Surgery) are based on the use in the perioperative period of measures that are supported by current scientific evidence. Since 2000 appear in the scientific literature several works that reflect the application of protocols ERAS or Fast- Track in surgery of the digestive system where it's shown uniformly, not only the security of your application but also, decreased complications and hospital stay. Although initially these protocols were described in colorectal surgery, due to the good results obtained, the application of these protocols has rapidly expanded to other surgical specialties such as thoracic surgery, Urology, Gynaecology, etc. In all these specialties has unanimously showing improved postoperative recovery with ERAS application protocols. The purpose of this paper is twofold. On the one hand examine the scientific evidence that exists today on the most important elements of an ERAS program and present preliminary results of the implementation of a program ERAS in our hospital.

El complejo respiratorio bovino (CRB) es la principal causa de enfermedad y muerte en el ganado de engorda en todo el mundo. Es un síndrome infeccioso multifactorial provocado por distintos virus y bacterias que disminuyen la eficiencia productiva y ocasionan pérdidas económicas. En México, el CRB se ha reportado en todas las regiones donde se engorda ganado; sin embargo, esos reportes carecen de información sobre la presencia del coronavirus respiratorio bovino (CVB), haciendo necesario contar con herramientas de diagnóstico confiables y precisas para detectar la presencia de CVB en el ganado que se engorda en México, para proponer las medidas sanitarias apropiadas para su manejo clínico. En este trabajo, se desarrolló una plataforma de diagnóstico molecular de PCR en tiempo real (rt-PCR) que amplifica un fragmento de la proteína S del CVB en muestras de exudado nasal. Al aplicar la plataforma rt-PCR para CVB en bovinos de engorda en aparente estado de salud y con signos de enfermedad respiratoria asociados a CRB se encontró que 19/50 (38 %) resultaron positivos, confirmando la presencia de ese virus en el ganado de la región. Los resultados de este trabajo significan el primer reporte sobre la presencia del CVB asociado al CRB en la región ganadera del noroeste de México y sienta las bases para futuras investigaciones sobre papel que juega este virus en la presentación de la patología del CRB en los sistemas de explotación de bovinos de engorda en nuestra región y el país.
