The response of dental personal to dental avulsion is very important and protocols on traumatic injury management should be known. The objective of this study was to determine the degree of knowledge of the management of dental avulsion of a representative group of dentists in the city of Cuenca, Ecuador. 183 dentists participated in the cross-sectional survey. Results highlighted that 42% of the surveyed dentists said that they had received some, but minor, information on dental trauma management, and 74.8% of those surveyed are not familiar with the recommended IADT protocols on traumatic injury management. The majority of participating dentists have a poor understanding of dental avulsion management, in contrast to the dental specialists in the surveyed population; the latter are clearly better able to manage this injury. Therefore, it is recommended that dental trauma should be included in the academic program in university schools of dentistry in Ecuador.

However, in the literature, the last two are poorly addressed or, in certain cases, unknown, especially in the study of adolescent sexual behavior. For this reason, the objective of this study was to explore the different types of coital behavior in adolescents and to visualize possible differences according to socio-demographic factors: sex, age, religious belief, parental migration. The research was carried out in Cuenca, with a sample of 2051 school-aged adolescents (15 to 19 years old). The sample was randomly established. The instrument used was the self-administered questionnaire \"Human Sexuality Questionnaire\" (Zuckerman, 1998). The results show that 61% of the participants reported not having had any type of intercourse. Among those who have had intercourse, vaginal intercourse was the most frequent type (36%), followed by oral intercourse (25%) and anal intercourse (19%). The frequency of intercourse was greater in men than in women; but it increased in both groups according to age. In women, vaginal intercourse was lower among those who practiced some religious belief. The present re-search evidences that adolescents who express having had coital relationships, indicate to have been involved in the different types of intercourse: oral, anal and vaginal; and its visualization provides guidelines to understand it as part of the adolescent's sexual development and to include these as necessary elements in the generation of sex education programs based on their context.","PeriodicalId":33189,"journal":{"name":"Maskana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45462149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thereto, we performed a retrospective qualitative study to know the quality of life improvement after thymectomy in non-thymomatous Myasthenia Gravis patients. Seventeen patients in the period January 2003 to December 2013 met the inclusion criteria: extended thymectomy, Myasthenia Gravis confirmed, non-thymomatous, over 18 years-old. We applied the SF-36 questionnaire and the collected data were tabulated and analysed with SPSS 22.0. The Wilcoxon test for non-parametric data was used to investigate any change in the quality of life after surgery. Quantitative surgical outcome of these patients was: 52.9% had significant clinical improvement according to the Oosterhuis scale (total remission = 5, mild symptoms = 3, mild disability = 1), of which 17.6% had complete stable remission without medication and 35.2% had pharmacological remission with low doses.

Esta especie polifaga, incluida en el grupo de los comunmente conocidos como gusanos cogolleros, es considerada una plaga, de efectos economicos de importancia, en varios paises del continente americano. En el maiz, estas larvas causan danos desde el estado de plantula hasta la etapa de pre-madurez. Sin embargo, la identificacion de los lepidopteros normalmente se realiza en base a la morfologia de los adultos y, por lo tanto, las larvas tienen que criarse hasta el estado adulto para su identificacion. Actualmente, el uso de herramientas moleculares como la PCR, basada en secuencias de ADN mitocondrial o nuclear, son utilizadas para identificacion inequivoca de plagas o biotipos a partir de larvas. El objetivo de esta investigacion fue identificar, a nivel molecular por analisis de PCR, la presencia de la especie S. frugiperda en cultivos de maiz blanco en el Sur del Ecuador. Para el efecto se colectaron un total de 360 larvas en 36 sitios distribuidos en tres provincias: 18 en Azuay, 12 en Canar y 6 en Loja, entre los meses de enero a marzo de 2015. La identificacion molecular se realizo con primers especificos para S. frugiperda a nivel del gen mitocondrial de la subunidad 1 citocromo oxidasa (COI) I. Como resultado se generaron amplificaciones de pesos moleculares de aproximadamente 500 pb correspondientes a S. frugiperda. Esta caracterizacion molecular es, a nuestro conocimiento, la primera que se realiza para el Austro del Ecuador. EnglishSpodoptera frugiperda is an insect pest of corn. This polyphagous species is included within the group of the armyworms, considered pests of economic importance in several countries of America. In corn, these larvae cause damage from the seedling to pre-ripeness stages. Identification of Lepidoptera is usually based on the morphology of adults, meaning that larvae must reach adulthood for their identification. Nevertheless, the larval period is the stage that causes mayor damage in corn. Currently, the use of molecular tools such as PCR, based on mitochondrial or nuclear DNA sequences, has been used for unambiguous identification of pests or biotypes from larvae. The objective of this study was to identify the presence of S. frugiperda species in white corn crops in the South of Ecuador at molecular level. For this, we used a PCR analysis with specific primers for S. frugiperda at the level of the mitochondrial gene of subunit 1 cytochrome oxidase (COI) I. A total of 360 larvae were collected in 36 sites distributed in three provinces: 18 in Azuay, 12 in Canar and 6 in Loja, between January and March 2015. As a result, amplifications of molecular weights of approximately 500 pb corresponding to S. frugiperda were generated. This molecular characterization is, to our knowledge, the first one performed for the Austro of Ecuador.","PeriodicalId":33189,"journal":{"name":"Maskana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47188566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here it is found that the literature best-suited for the conditions of Manabi includes literature for semi-arid, savannah and humid tropical hydrology. Several research gaps are found, but also a significant body of knowledge that could serve as a base for future studies. It should be noted that much of the available literature was obtained with vegetation and soil conditions that might differ from those of Manabi. Therefore, it is essential that findings from abroad are contrasted with results obtained in Manabi.

Understanding the dynamics of soil moisture response under pristine vegetation cover during rainfall events is essential for water resource planning considering the increasing anthropogenic pressure. Hence, this study focuses on the evaluation of the factors and thresholds controlling maximum changes in soil moisture (Δθmax) during rainfall events and their dynamics during different wetness conditions (from dry to wet). To determine the factors controlling Δθmax, a nonparametric Spearman correlation coefficient test was applied. We found that the factors controlling Δθmax were the precipitated volume, intensity, moisture conditions just before the event and the 5- and 15-days antecedent weather conditions. The threshold analysis shows a response of increase or decrease as function of moisture state, topographic position and soil layer depth. This study demonstrates that under pristine Andean Paramo vegetation precipitation, antecedent moisture and weather conditions determine to a significant degree the soil moisture status affecting subsequently hillslope connectivity and hydrologic functioning.","PeriodicalId":33189,"journal":{"name":"Maskana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47719529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is intended to define the Cadmium concentration in 36 samples of fresh tuna and canning, respectively from the Caraguay Market in the city of Guayaquil, the fishing port Santa Rosa (PPSR), and canned tuna for national consumption and export. The cadmium concentration in the tissue of the collected tuna samples was analyzed by atomic absorption spectrophotometry. Levels of cadmium concentration in the analyzed samples were compared to the national regulation norm NTE INEN 183 and 184, and the European Union regulation norm No 488/2014. According to those norms the maximum permissible cadmium content in foodstuff might not exceed 0.10 ppm Cd. In canned tuna for national consumption we found concentrations of 0.441±0.046 ppm Cd and in the canned tuna for export the cadmium level varied around 0.297±0.109 ppm; differences were however not statistically significant (p>0.05). Similarly, the Cd concentrations in fresh tuna of the species Katsuwonus pelamis was 0.385±0.174 ppm and of the species Thunnus albacares 0.295±0.187 ppm in the market of Caraguay. In contrast, Cd concentrations in tuna from the PPSR were much lower: 0.079 ± 0.061 ppm Cd and 0.030 ± 0.050 for Katsuwonus pelamis and Thunnus albacares, respectively. 66% of the analyzed samples exceeded the permissible limits of Cd according national and international standards.
