LA INVESTIGACIÓN Y SUS PASIONES EN LA UNIVERSIDAD ECUATORIANA: VOCES, RESISTENCIAS Y PERSPECTIVAS
Authors: Fontaines-Ruiz Tomás
Published: August 2018

El Estado ecuatoriano, al autoevaluarse en el marco de su reforma constitucional en el 2008, cuestiona la calidad, pertinencia, escalabilidad y visibilidad de sus universidades. Toma conciencia de la urgencia de una reingeniería e implosiona la interacción socio discursiva, provocando nuevas sinergias y nuevas identidades, por ello, en este estudio explico cómo se produjo la trama de sentidos que hizo de la investigación universitaria, un activo dentro de la transformación de la educación superior ecuatoriana. Se parte de la idea que los factores sociopolíticos condicionan la adopción epistémica y curricular, en consecuencia, los cambios estructurales son posibles en presencia del Estado. Se concluye que la voluntad del poder,  puesta al servicio de la reingeniería política, posicionó la investigación como un activo dentro de la transformación educativa del país, proyectándolo hacia la soberanía tecnológica como consecuencia del crecimiento de sus intangibles.

LAS NARRATIVAS DE LOS PADRES Y LOS VIEJOS PROBLEMAS DE LA EDUCACIÓN
Authors: Nogueira Gracilene Mendes de Souza , Nunes Cláudio Pinto
Published: August 2018

Este estudio tiene como objetivo discutir los problemas de la educación naturalizados en las escuelas públicas y que, a pesar de comprometer su desempeño, no han perdido fuerza con el tiempo. Los argumentos que apoyan esta discusión se construyeron a través de las narrativas de padres de alumnos matriculados en la enseñanza básica de nueve años, producidas a través de la conversación interactivo-provocativa y analizadas de acuerdo con los presupuestos teórico-metodológicos de la Epistemología Cualitativa. La investigación se justifica por la forma inestable como esta política sigue desarrollando desde su creación en 2007, cuando vista desde la perspectiva de la gestión escolar democrática. Los padres, los primeros interesados ​​en la educación de sus hijos, son sujetos capaces de producir informaciones dotadas con sentidos subjetivos, permitiendo la construcción permanente de modelos de inteligibilidad que afectan directamente la relectura de experiencias profesionales y personales de profesores de la enseñanza básica y la promoción de debates en el universo de las Ciencias. Aunque no mantenga una relación linear con los aspectos objetivos de la realidad, las narrativas nos permiten comprender, a través de la subjetividad de los sujetos, como condicionantes internos a la participación interfieren en la implementación de la enseñanza básica de nueve años, haciendo de este tema un punto de convergencia de viejos conflictos educacionales.
PROTAGONISMO INDÍGENA NO TEMPO PRESENTE:
Authors: Fernandes Fernando Roque
Published: August 2018

Falar de História Indígena é, sobretudo, abordar as agências indígenas nos processos históricos nos quais estiveram inseridos, reconhecendo sua agência, seu protagonismo e sua atuação. Desde meados do século XX, os povos indígenas têm sistematizado atuações políticas por meio de instrumentos recorrentes entre os não índios, sem abandonar suas práticas milenares. Os movimentos indígenas atuam de modo amplo, pautando demandas e alcançando conquistas. Dentre elas, a Educação é uma baliza importante. Nesse sentido, o objetivo deste texto é apresentar elementos que nos permitam refletir sobre as articulações indígenas por uma educação específica e diferenciada sopesando o lugar que ela ocupa nos processos políticos nos quais os indígenas estão inseridos e seus desdobramentos. Os apontamentos apresentados informam indícios e rascunham interpretações, desde uma perspectiva que privilegia o protagonismo indígena. Assim, encaminhamos um ensaio acerca da evolução do panorama educacional vinculado à questão indígena, indicando alguns apontamentos acerca dos dados reunidos no início de uma pesquisa sobre Educação Escolar Indígena na Amazônia Brasileira. Por meio dela, pretendemos indicar um nexo que, segundo nos parece, deve ser ressaltado: a importância do protagonismo indígena na conformação de uma política de Estado para a Educação Escolar Indígena. Desse modo, o texto dá os primeiros passos na reflexão não somente dos nexos que ligam aquela educação às lutas dos movimentos indígenas, mas, também, na ponderação acerca de uma inflexão nas políticas indigenistas, as quais, nos últimos anos, passaram a contar com a participação direta dos coletivos indígenas.

Authors: Leão Lucas Diógenes , Barros João Luiz da Costa
Published: August 2018

O presente estudo almeja colocar em evidência o tema da “formação de professores de educação física no Brasil”, em busca de respostas as seguintes questões: quantos estudos foram encontrados e discutidos nas pesquisas produzidas sobre a temática indicada? Quais foram as evidências? O que os estudos consideraram? Objetivamos analisar as produções científicas nacionais a partir de uma revisão sistemática sobre a formação de professores de educação física no Brasil divulgadas no meio científico. Selecionamos os estudos utilizando os indexadores do banco de dados de periódicos científicos brasileiros Scielo, na biblioteca digital da Associação Nacional de Pós-Graduação e Pesquisa em Educação e no Portal Domínio, onde inserimos o descritor “formação de professores de educação física” e o período estipulado foi dos anos de 2014 a 2017. Foram selecionados 26 artigos científicos. Na análise textual dos achados verificamos que os autores mais referenciados foram Maurice Tardif e Antônio Sampaio da Nóvoa, sobretudo considerando que os principais conceitos relacionados a formação de professores de educação física no Brasil, referem-se a: Formação inicial, Formação continuada, Ciclos ou fases da carreira profissional, Importância das primeiras experiências na atuação profissional e Atividades e conteúdos dos profissionais docentes em educação física. Apesar dessa variedade de assuntos relacionados ao tema da formação de professores, o que nos chamou atenção foi pouca referência a autores específicos da área da educação física Dessa forma, é relevante que estudos sistematizados sobre o tema investigado continuem presentes no meio científico e que tais revisões se ampliem para teses e dissertações.

Published: August 2018

Kepuasan kerja merupakan salah satu faktor yang sangat penting untuk mendapatkan hasil kerja yang optimal. Ketika seorang merasakan kepuasan dalam bekerja tentunya ia akan berupaya semaksimal mungkin dengan segenap kemampuan yang dimilikinya untuk menyelesaikan tugas pekerjaannya. Dalam kenyataannya, di perusahaan, kepuasan kerja secara menyeluruh belum mencapai tingkat maksimal. Masa kerja seseorang akan terpengaruh apabila mendapatkan suatu rangsangan, sehingga orang tersebut mampu mempersepsikannya dengan lebih baik pula. Adanya proses belajar atau pemahaman yang diperoleh seseorang melalui intensitas hubungan yang diperoleh dari masa kerja menjadikan seseorang mampu mempersepsikan kondisi kerjanya lebih baik ataupun lebih buruk. Oleh karena itu tujuan penelitian ini untuk mengetahui tingkat kepuasan kerja karyawan dan bagaimana cara mengekspresikan tingkat kepuasan kerja yang rendah pada karyawan dengan masa kerja di atas tiga puluh tahun. Jumlah subyek penelitian yang digunakan sebanyak 72 karyawan yang bermasa kerja di atas tiga puluh tahun pada jabatan kepala regu (karu), di sini peneliti menggunakan teknik sampling jenuh. Metode pengumpulan data menggunakan kuesioner yang disusun dalam bentuk skala likert, data kedua variabel diolah dengan teknik persentase. Hasil penelitian menunjukkan bahwa terdapat 22 karyawan (30,6%) yang memiliki tingkat kepuasan kerja rendah, 30 karyawan (41,7%) memiliki kepuasan kerja sedang, 20 karyawan (27,8%) memiliki kepuasan kerja tinggi. Faktor-faktor yang mendukung tingkat kepuasan kerja sebagian besar karyawan meliputi tersedianya perlengkapan pegawai yang memadai, kesejahteraan pegawai terjamin dengan adanya layanan kesehatan, dan tersedianya sarana ibadah yang baik. Faktor yang kurang mendukung tingkat kepuasan kerja sebagian karyawan meliputi hasil penelitian kinerja tidak ada umpan balik, penerapan peraturan kurang tegas dan kurang adil, dan belum adanya sistem karir (carrier planning) yang jelas. Sebagian besar cara mengekspresikan tingkat kepuasan rendah cenderung destruktif dan dalam bentuk pindah ke unit kerja lain.

Published: August 2018

Cervical spine injury is rare in children. It is seen primarily in those who sustain significant, severe blunt trauma, occurring in 1 to 2 percent of such cases. The interpretation of cervical spine radiographs and the clinical examination in children may be difficult.The objective of this case clinic is to report on a physiological radiographic finding of the cervical spine in childhood that trends to be misjudged as pathologic: C2-C3 pseudosubluxation. We presented a boy, aged 5 years, who came to our Traumatic pediatric emergency center for cervical pain after falling from a height. In lateral radiographs we observed a disruption of the alignment of the anterior and posterior vertebral body line in C2-C3 space. A detailed anamnesis as well as a meticulous radiological and clinical exploration, allow to establish the right diagnosis in most cases, without any other complementary probe. Pseudosubluxation of C2 anterior to C3 is seen in approximately 40 percent of children under the age of 8 years. Pseudosubluxation can be differentiated from true subluxation by evaluating the spinolaminal line (Swischuk), line between the anterior aspects of the C1 and C3 spinous processes. The suitable radiographic interpretation of the cervical spine in children requires the knowledge of the peculiarities of this segment in the pediatric age.

Published: August 2018

SUMMARY:Background: Acute appendicitis neither suspected nor diagnosed could develop a perforation or otherwise it would take to removing of a normal appendix. Objectives: Utilization of a clinical score system for aided diagnosis of this pathology and can reduce a negative appendicitis.Setting: National Clinicas Hospital. Córdoba. Argentina.Design: Prospective and protocolized study.Methods: 594 patients were studied between October 2002 and December 2013. 312 males and 282 females their age average was 26.2 years. Alvarado score was realized in all patients when they entered. According clinic and second valoration with the score surgical exploration was decided in 574 patients. The remaining 20 were excluded due to other pathology. The diagnosis in acute appendicitis was confirmed by surgical finding and histopathologic studies. Results: In surgical finding we showed 594 patients (91,28 %) had acute appendicitis. There was no operative mortality. Respects morbidity there was 1,74 % of medical and 13,93 % of surgical complications. The anatomo-pathologic report showed a normal cecal appendix in 50. The incidence of negative appendicectomy was about 8.71 %.Conclusions: The utilization of score related to the surgical and anatomo-pathologic finding confirmed it was appreciable from 6 points to acute appendicitis diagnosis.
Evaluación de ecuaciones que utilizan cistatina c para estimar filtrado glomerular en adultos sanos candidatos a donantes renales
Authors: Medina Arnaudo Gisel Ivana
Published: August 2018

The determination of the glomerular filtration rate (GFR) is critical for the selection of potential kidney donors. Methods of measurement of GFR are impractical and complex, which led to development of equations to estimate GFR. Objective: To evaluate of the performance of Creatinine and Cystatin C based equation for estimation of GFR in healthy adult population of candidates for kidney donors. Materials and Methods: a cross-sectional study was performed in 72 adult patients evaluated as candidates for kidney donors. GFR was measured by nonradiolabeled Iothalamate clearence (mGFR). GFR was estimated by the Modification of Diet in Renal Disease (eGFR MDRD) equation, Chronic Kidney Disease Epidemiology Collaboration study (eGFR CKD-EPICREAT, eGFR CKD-EPI-CREAT+CYSC) and the equation proposed by Stevens et al. (STEVENSCREAT+CYSC). The overall performance of all equations was analyzed. Results: eGFR CKD-EPICREAT+CYSC, eGFR STEVENS CREAT+CYSC and eGFR CKD-EPI-CREAT presented lower bias (1,93; - 0,71; -1,53 mL/ min/1,73m2 respectively) compared with eGFR MDRD (bias= -10,36 mL/min/1.73m2). This study demonstrated that the best diagnostic performance was shown by eGFR CKD-EPICREAT+CYSC (LR(+)=9,8; “Positive Likelihood Ratios”), followed by eGFR STEVENSCREAT+CYSC (LR(+)=4,7) and eGFR CKD-EPICREAT (LR(+)=3,7). Discussion: CKD-EPICREAT+CYSC, STEVENS-CREAT+CYSC and CKDEPI-CREAT equations demonstrated a clearly higher performance to estimate GFR compared with MDRD in the study population.
Caracterización de los subtipos de VIH-1 presentes en Córdoba (Argentina) desde casi el inicio de la infección, utilizando los genes POL y ENV

Published: August 2018

Objective: In the present study we characterize, using a retrospective approach, the HIV-1 infection in Córdoba, Argentina, by determining the viral subtypes circulating in the period 1986-2001. Methods: The pol and env genes were analyzed using two different approaches: 1) comparing the sequences from Córdoba with those of pure subtypes and circulating recombinant forms of the HIV-1 M group; 2) subdividing the sequences into pure-subtype data sets (avoiding the effects of recombination) to determine if the subtypes from Córdoba have a single or multiple geographic origins. Results: The first approach revealed that eighteen strains were subtype B, seven B/F1, one C and one F1. Only two of the B/F1 corresponded to the CRF12_B/F1, previously described for Argentina; the remaining B/F1 sequences could be considered different forms of URF_B/F1. The Phylogenetic results of the second approach suggest that in Córdoba subtype B would have multiple geographic origins, while subtypes F1 and C would have been introduced directly from Brazil or indirectly from Buenos Aires. Conclusions: The great subtype variability indicates that the HIV-1 infection in Córdoba was complex since its very beginning. Our results also reveal the close contact of people of this city, through tourism and commercial activities, with those from Buenos Aires and Brazil.

Published: August 2018

Different thyroidectomy techniques have been developed to improve the aesthetic results, postoperative pain and to reduce hospital stay. Objective: To demonstrate the feasibility, safety and efficacy of minimally invasive video-assisted thyroidectomy (MIVAT). Design: Retrospective Methods: Ninety six patients with thyroid nodules were selected for MIVAT if they presented nodules under 35 mm in diameter, thyroid volume below 30 ml and absence of high-risk malignant tumor, lateral cervical lymphadenopathy or prior cervical surgery. Indirect laryngoscopy was performed before and after surgery to all patients. Surgery was performed through a midline incision of 1.5 cm above the sternal notch, without carbon dioxide and with magnification endoscopy. We evaluated postoperative complications, pain after surgery, the cosmetic outcome and length of stay. Results: Ninety patients underwent total thyroidectomy or near-total thyroidectomy. The average operative time was 54 ± 9 minutes. The average diameter of the nodule was 20 ± 6 mm. The average volume was 19 ± 6 ml. We documented six (6.2%) hyperparathyroidism and one recurrent laryngeal nerve palsy (0.96%), both transient and none of them permanent. The postoperative pain was minimal and all patients were discharged within 24 hours. Conclusion: In our experience the MIVAT is a safe and feasible technique for the treatment of thyroid disease, with clear advantages over conventional thyroidectomy in selected patients.

Authors: Dipierri José Edgardo , Bronberg Rubén Adrian
Published: August 2018

Due to the increase in cases of microcephaly caused by Zika virus in Brazil, the Ministry of Health of Argentina recommends increasing surveillance of this malformation. In order to deepen the knowledge of the epidemiological behavior of microcephaly in the country, infant mortality by microcephaly is analyzed between 1998 and 2012. The data come from the Direction of Statistics and Health Information (DEIS). The infant mortality rate by microcephaly (IMR-M) was calculated by provinces and regions and a clustering analysis was performed at the departmental level. The highest rates were observed in the regions and provinces of the north of the country. The spatial distribution of IMR-M is related to the prevalence of microcephaly in newborns. This distribution is related to the greater poverty and consanguinity of the north of Argentina, synergic factors predisposing to the occurrence of congenital malformations in general and microcephaly in particular.

Published: August 2018

Introduction: Smoking is the leading preventable cause of death in the world. Electronic Cigarette (EC) is a device that simulates a conventional cigarette and allows inhale nicotine and other substances in a vaporized form, without combustion of snuff. Because it´s marketing and availability, it´s use comes with a steady increase. It is used worldwide to reduce the consumption of snuff, achieve their abandonment or in public places where consumption of conventional cigarettes is prohibited. Harmful effects on health: The use of EC has been associated with lipoid pneumonia and irritation of the upper airway as well as nicotine toxicity. It also contains carcinogens such as nitrosamines, formaldehyde and metals such as nickel, chromium and lead substances. It increases the airway resistance these effect is similar to those that occur after inhaling smoke snuff. Effective smoking cessation: At the moment, there is no scientific evidence with adequate methodology and statistical power that have demonstrated the effectiveness of EC in smoking cessation. Conclusions: According to the available evidence, it seems that EC encompasses some health risks while its effectiveness in smoking cessation has not been proved yet.

Published: August 2018

Sixty-five cases of enterobiasis of the cecal appendix are reported by Enterobius vermicularis or Oxiurus vermicularis. Enterobiasis is a cosmopolitan parasite5,8,13 and frequent. It is useful to establish whether it can cause appendicitis and the mechanisms involved. According to the classical literature, E. vermicularis is not a causative agent of appendicitis per se, but allows the reproduction of the germs that infiltrate the wall and produce appendicitis5,9,10. The purpose of the study is to report the prevalence of E. Vermicularis in surgical appendicitis and the anatomopathology to deduce a causal relationship. We report a sample of 2000 surgical pieces of extracted appendages (1992-2003) at the Emergency Hospital of the city of Córdoba, Argentina. On a total of 2000 pieces, we observed 65 cases of appendicular enterobiasis; in 60 cases (3.25%) there was no histopathology of acute inflammation (anodyne cecal appendix). In the remaining 5 cases (0.25%) we observed coexistence of parasites in the appendicular lumen, acute transmural inflammatory infiltrates (acute appendicitis) and fecalitos, which would support the obstructive type etiopathogenesis that leads to the surgical picture. The appendicular location of Enterobius vermicularis would favor the formation of fecalitos in light and the proliferation of germs in the wall that would lead to appendicitis. Reports indicate that the parasitic infection constitutes a percentage of the etiologies in appendicitis and fecalitos are the most common trigger, some parasites (Enterobius vermicularis) may be involved in its formation, although this percentage is minimal9,10,15,16,17 .

Published: August 2018

Introduction: The incorporation of the clinic and the imaging allow a better understanding of anatomy. The aim of this work is to develop a rapid prototype in synthetic material that replicates anatomical details to be used in teaching and surgical training in Pediatrics. Material and method: presentation of case: one year old female with respiratory distress syndrome. In the endoscopic examination was found a distal tracheal compression. The angiotomography confirmed the presence of a vascular malformation. In order to discuss appropriate conduct, the making of rapid prototyping in scale 1:1 was requested to simulate an identical condition of the thoracic topography of the patient, using virtual 3D images stored in the DICOM format. Rapid prototype technique: code "g" was generated, which was used to control the hardware of production and a three-dimensional digital grid was obtained. Digital simulation and production in plastic (ABS) with deposition and fusion technique (MDF) was performed. The prototype was validated by comparing measurements with witnesses of the virtual model in 3 D. Results and discussion: the model replied exactly the defects found in the scan and endoscopy, confirming the presence of vascular malformation and its impact on the respiratory system. Rapid prototype shows the internal and external structures of the human body with maximum precision allowing a topographic view of "normal or pathological" situations that could facilitate the teaching and training of the surgical team to propose an appropriate treatment plan. There are many areas of medicine that could benefit from this model that could be built with different types of materials with different flexibility and consistency. Conclusions: Rapid prototype gives form to virtual 3D images, allowing teaching and training of the surgical team.

Vaccination against rotavirus in Argentina is obligatory from January 2015. From 418 stools in children with acute diarrhea were collected from 2000 to 2010 in city of La Rioja, Argentina, Rotavirus was detected. The 90 rotavirus positive stools samples (21.53%) were amplified by RT-PCR and genotyped by PCR-Mix for G1, G2, G3, G4, G9 and G8. The results show that during 2000-2003, the most frequent genotype was G1 and but since 2008, the G2, G3 and G9 genotypes in single and mixed infections were detected.
In La Rioja, the vaccines could prevent dehydration in older children the year but children under one year could be vulnerable to the emergence of strains with genic aberrations due to the implementation of vaccination in our region.
Actividad moduladora in vitro de extractos acuosos de plantas americanas sobre la toxicidad inducida por clorpirifos en esplenocitos murinos
Authors: Scotta Ana Verónica , Bongiovanni Guillermina Azucena , Soria Elio Andrés
Published: August 2018

Background: Chlorpyrifos is an highly toxic pesticide, which can induce immunotoxicity with deleterious effects on health worldwide. On the other hand, American plants can provide derivatives with protective and immunostimulating activity. Thus, plant potential against chlorpyrifos should be assayed. Objective: To identify bioactive aqueous extracts from Lantana grisebachii (LG), Aspidosperma quebracho-blanco (AQ), Peumus boldus (PB), and Ilex paraguariensis (IP), against chlorpyrifos-induced toxicity on female Balb/c splenocytes. Material and method: Splenocytes were treated in vitro for 72 hours with 0-35 µg/mL of chlorpyrifos, 0-100 µg/mL of each extract (LG, AQ, PB, IP), and 0-5 µg/mL of concanavalin A. Then, cellular viability and death (resazurin-based and propidium iodide stainings), hydroperoxides, lipoperoxides (xylenol orange-based assay), ?-glutamyl transpeptidase activity (Szasz method) were measured and analyzed statistically. Results: Chlorpyrifos reduced splenocyte viability in a dose-dependent manner, which was counteracted by AQ and IP, which was less active in concanavalin A-responsive cells (p<0.05). Chlorpyrifos toxicity involved ?-glutamyltranspeptidase induction with a consequent peroxide reduction, whereas AQ and mainly IP antagonized these responses (p<0.05). Conclusions: The extracts of Ilex paraguariensis and Aspidosperma quebracho-blanco protected splenocytes in vitro against chlorpyrifos. This effect depended on cellular type, given that concanavalin A-responsive cells were more susceptible to this toxic.

Published: August 2018

Background: Plant extracts can be obtained to carry bioactive compounds, useful for prevention and treatment of different illnesses. This also supports the intake of teas as functional beverages. Nonetheless, it is incompletely known whether these extracts can act as effective sources and vehicles de phenolic compounds (phenolics/polyphenols) to reach their targets. Objective: To establish whether phytoextract ingestion modified in a sex-dependent manner the phenolic bioavailability and redox response in liver and kidney. Method: BALB/C mice ingested for a month 100 mg/Kg/d of extracts (tea-like) from Aspidosperma quebracho-blanco (AQB), Lantana grisebachii (LG) or Ilex paraguariensis (IP). Then, phenolics, peroxides and nitrites were analyzed by spectrophotometry. Also, phenolic permeation from digested and undigested extracts was evaluated in vitro with a rat jejunum-based assay. Results: Phenolic permeation depended on extract digestion. In males, IP showed a special time course of hepatic phenolics, whereas all extracts decreased renal phenolics at 15 days. Extracts induced hepatic lipoperoxides at 15 days. LG reduced renal hydroperoxides at 15 days and hepatic nitrites at 30 days, whereas AQB and IP reduced renal lipoperoxides and nitrites at 30 days. In females, extracts reduced hydroperoxides, with LG and AQB also reducing lipoperoxides. IP increased renal lipoperoxides at 30 days. Conclusion: IP was a relevant phenolic source. Sex-dependent responses were found in all variables, which should be considered to prevent misleading generalizations in phytodrug bioprospecting.

Objective. Show our experience performing the minimally invasive video-assisted parathyroidectomy with central approach for the treatment of patients with primary hyperparathyroidism without using intraoperative parathyroid hormone monitoring (IPTHM) based solely on the concordance of two preoperative localization studies.Material and methods. An informed consent for the accomplishment of a minimally invasive approach was performed on 27 selected patients diagnosed with primary hyperparathyroidism who underwent pre-operative cervical ultrasound and sesta-MIBI scintigraphy studies, which were consistent across them. None had a family history that might indicate a multiple endocrine neoplasia (MEN), known thyroid disease, previous neck incision, or suspicion of carcinoma. Surgery was performed through a 1.5 cm central cervical incision and the use of harmonic scalpel. IPTHM was not performed in either case.Results. In all cases the topographic location of the adenoma was confirmed. No signs of hyperparathyroidism persistence or recurrence were registered after a follow-up period of 42 months. There were no recurrent nerve lesions. The average operative time was 24.5 minutes and all patients were discharged within 24 hours. The analgesic requirement was minimal and the cosmetic result satisfactory.Conclusion: The minimally invasive unilateral exploration of the parathyroids with video-assisted magnification without IPTHM, under the guidance of two concordant localization studies is safe and feasible, with comparable results to those of standard technique as well as aesthetic advantages, less postoperative pain and reduced hospitalization.

Introduction: Malignant pleural effusion (MPE) involves advanced cancer disease. Pleural biopsy for endoscopic thoracic surgery allows diagnosis in more than 90% of cases and instrumentation of the pleural space, improving the results of the technique.Material and Method: We performed a retrospective analysis of patients with MPE who underwent a talc chemical pleurodesis. Two groups were formed, one with complicated malignant pleural effusion (CMPE) and another with uncomplicated malignant pleural effusion (NCMPE). In the group with CMPE, "release - expansion maneuvers" were performed. The variables between the two groups were compared for the relevant analysis.Results: We analyzed 28 patients with MPE treated with chemical pleurodesis by endoscopic thoracic surgery. The average age was 62.64 years. Pleural involvement due to breast disease was the most frequent form (46.4%). There was no difference between complication rate (p = 0.31) and the risk of death at 30 days (p = 1.09) with aggressive management of pleural space. The delay pleurodesis indication was related to a higher rate of complications (p = 0.002) and a higher probability of death within 30 days (p = 0.008). The majority of patients return to their daily tasks, with good tolerance to dyspnea following the procedure.Conclusion: In patients with complicated MPE, the "lung-release maneuvers" described above would increase the chances of improving outcomes at low risk. Early chemical pleurodesis improves the quality of life of patients with PND.

Background: Diseases of the orbit represent a surgical challenge, particularly those compromising the orbital apex. Optimal surgical access should provide the best possible exposure, allowing to identify certain key anatomical structures, called landmarks. Objective: Describe the endoscopic anatomy of the structural unit formed by the Inferior Orbital Fissure (IOF) and the Müller’s muscle (MM) at the orbital apex (OA), thus generating a new endoscopic anatomical landmark. Materials and methods: A bone-descriptive analysis of the IOF in dry craniums, was followed by dissection and endoscopic study of six heads (twelve sides), colored and fixed in formaldehyde. In ten dry craniums (twenty sides), distances and angles of OA foramina were measured (optic foramen [OF] and foramen rotundum [FR]). Statistical analysis was performed with SPSS 17.0 statistical software (SPSS, Inc. Chicago, IL). Results: The structural unit IOF-MM was identified in all endoscopic dissections, verifying its intimate relationship with the OA. From the morpho-metric standpoint, OF and FR were found at an average distance of 65.19 mm and 60.16 mm, respectively. The average angle of the OF was 13.32 degrees, whereas the one for FR was 19.31 degrees. We found a significant correlation between OF and FR only on the left side (left hemi-crane) (Kendall Tau b 0.69, p=0.006). There were no anatomical or morphological differences between both sides. Conclusion: The unit IOF-MM is a constant anatomical landmark, useful and safe under endoscopic technique, which allows the recognition of the OA and its contiguous areas.

Objective: to evaluate the impact of air pollution and weather changes on the number of visits to a pediatric emergency department in Buenos Aires, Argentina. Materials and methods: we designed an ecological time-series study using generalized additive models (GAM) for the period 2012-2014. The outcome variable was the number of daily visits to a pediatric emergency department taking into account daily consultations. The potential predictors were the average daily air pollution levels (carbon monoxide -CO-, nitrogen dioxide -NO2-, particulate matter 10 microns or less in diameter -PM10-) and weather variables (temperature, humidity, wind speed and direction, and rainfall) and we controlled by weekday and long-time trend. Results: the number of visits during the winter months (286 daily) was significantly higher than those in the other seasons (p <0.0001). The change in air pollution levels did not show a significant and consistent correlation with the visits. Temperature, relative humidity, rainfall, and wind speed and direction were not significant variables for any of the examined lags. Conclusions: Considering the population and variables of our study, air pollution does not affect the health outcomes, as does seasonal epidemics. Studies that examine other health variables are necessary to establish the impact of air pollution on children’s health in Buenos Aires.

Introduction: It is undeniable that costs of medical care in chronic diseases has increased. There are multiple reasons: population aging, associated pathologies late complications, available high cost health technologies. Heart failure is one of the main causes of global death and morbidity, being the final consequence of cardiac diseases and hypertension, fulfilling criteria of becoming a high costs pathology. We are going to evaluate direct medical costs of hospitalization due to heart failure from the vision of those who manage health resources.
Materials and Methods: Observational, retrospective cohort using secondary databases from the Hospital Italiano de Buenos Aires. Adult population with diagnosed heart failure that required hospitalization with discharge diagnosis of  heart failure between 2007 and 2011.
Results: The main cost component was attributable to hospital bed, diagnostic and therapeutic interventions. The average incidence of hospitalizations during the period was 11.4 per 10,000 patients / year. Overall mortality in the episode rate was 0.25% per year and 28.8 % overall 60%
Conclusion: The most important decision seems decide whether management can be done on an outpatient basis or not, using heart failures guidelines to optimize time of admission, auxiliary diagnostic methods and medications used.

Introduction: The popliteal artery aneurysm (AAP) is localized and irreversible walls of the popliteal artery dilation. It is rare pathology is the second most common location of true aneurysms after aortic, and the first location within the peripheral aneurysms. It is characterized by affecting mainly men at an average age of 65, whose manifestations are mainly ischemic, finishing lower limb amputation in a frequency ranging as appropriate between 7 and 20 percent. Our goal is to make the presentation of a case of AAP with subacute arterial ischemia, along with a literature review of the topic. Case presentation: the case of a 63 year old who consulted for lower limb pain 96 hours of evolution, with absence of pulses is presented a diagnosis of advanced subacute ischemia was performed resvascularizable not in the context of a clinically unstable patient. emergency amputation is decided. In dissecting the presence of PSA objective. Discussion: The AAP have an incidence of 0.1 to 1%, have variable clinical. Arteriography is the gold standard for diagnosis. The treatment of choice is surgical, presenting new therapeutic options. The anatomical variations of the branches of the PA are variable to consider. Aneurysms are most commonly associated with contralateral popliteal (57.1%). Conclusions: We conclude that our conduct was appropriate considering the state of the patient.

Background: Based on the theory of probability and not equiprobable entropy ratios in the context of dynamical systems theory, a methodology for cardiac dynamic evaluation was developed. Objectives: To confirm the clinical applicability of the diagnostic methodology based on probability and entropy for patients with different types of arrhythmia assessing the degree of intensification in the ICU through its characteristic proportions. Methods: 80 Holter records from ICU diagnosed with arrhythmia and 20 normal were analyzed. Holter clinical findings were masked and were taken from them the maximum and minimum values of heart rate and total number of beats per minute to build the numerical attractor for each dynamics. Probability, entropy, S/k ratio, and proportions of entropy were evaluated, establishing its mathematical diagnosis and quantifying its severity level. Results: It was shown that the methodology difference in all cases normal of abnormal dynamics, obtaining a sensitivity and specificity of 100 % and Kappa coefficient of 1, showing that it is also possible to establish quantitatively the degree of exacerbation. Conclusions: The methodology developed is useful in clinical practice to correlate the severity of arrhythmias with physical and mathematical predictions of exacerbation.
