An assessment of mental health of Mexican and Colombian medical students during the COVID-19 pandemic / Una evaluación de la salud mental de estudiantes de medicina Mexicanos y Colombianos durante la pandemia de COVID-19

Abstract Introduction The COVID-19 pandemic caused the cessation of academic activities from the face-to-face format to confinement and virtual classes, in which little is studied about its effect on mental health. Objective Determine levels of depression, anxiety, and stress in medical students in Mexico and Colombia during the COVID-19 pandemic. Furthermore, depression, anxiety, and stress were compared by gender, education status, and country. Method A cross-sectional study was carried out with 426 medical students. Data was collected using an online survey containing the Depression, Anxiety, Stress Scale (DASS-21) questionnaire. Results Overall scores for depression, anxiety, and stress were 6.7 ± 1.2, 8.8 ± 1.2, and 5.6 ± 1.2, respectively. Females had significantly higher overall scores for depression (.24-fold increase), anxiety (.25-fold increase), and stress (.40-fold increase) than males (p ≤ .01). The risk for anxiety and stress by school year showed that basic years were associated with higher scores than advanced years (.25 and .38-fold increase, respectively). For females, starting medical school did show an increased risk of depression when compared to male students in their basic years (.38-fold increase). Lastly, students from Mexico had an increased risk for depression and anxiety (p ≤ .022 and p ≤ .004, respectively) but not for stress (p ≤ .402), when compared to students from Colombia. Discussion and conclusion Significant anxiety and depression were observed in medical students from Mexico and Colombia. Factors associated with an increased risk of depression and anxiety are students in their basic years as well as being female.

Resumen Introducción La pandemia de COVID-19 provocó el cese de las actividades académicas desde el formato presencial al confinamiento de las clases virtuales, de las que poco se ha estudiado sobre su efecto en la salud mental.

Relación entre la composición de la microbiota y la hipertensión arterial esencial. Una revisión narrativa / Relationship between microbiota composition and essential hypertension. A narrative review

La hipertensión arterial esencial es una patología de alta prevalencia a nivel mundial, y uno de los determinantes más significativos para enfermedad cardiovascular. Por otra parte, se ha generado un gran interés por la microbiota del cuerpo, y la forma en que se ve alterada por factores tanto internos como externos, ocasionando disbiosis. En la actualidad se viene estudiando el efecto de la microbiota en diferentes enfermedades, entre ellas, la relación entre la microbiota y la hipertensión. En este artículo se hizo una revisión de la literatura, entre 2010 a 2021, con el objetivo de identificar la evidencia científica que sustenta la relación entre la composición de la microbiota y la hipertensión arterial esencial. Se encontró en muchos estudios que los hipertensos tenían una diversidad menor de la microbiota, en comparación con los grupos de control sanos. En los hipertensos se encontraron principalmente bacterias del género Prevotella y en el grupo control predominaba el género Bacteroidetes. Adicionalmente, se observó una disminución de Faecalibacterium, Roseburia y Bifidobacterium en el grupo de hipertensos. Existen varias técnicas de laboratorio para el reconocimiento de la población bacteriana del intestino, tales como la secuenciación de la subunidad de ARNr 16S, la secuenciación del genoma completo y la metagenómica de la microbiota. A pesar de que los estudios realizados sobre la relación microbiota e hipertensión concluyen que existe una relación significativa entre ambas, es necesario hacer más investigaciones en diferentes grupos poblacionales

Essential arterial hypertension is a highly prevalent pathology worldwide and is one of the most significant determinants of cardiovascular disease. On the other hand, great interest has been generated in the microbiota of the body, and how it is altered by both internal and external factors, causing dysbiosis. Currently, the effect of the microbiota in different diseases is being studied, including the relationship between the microbiota and hypertension. In this article, a review of the literature was made, between 2010 and 2021, with the objective of identifying the scientific evidence that supports the relationship between the composition of the microbiota and essential arterial hypertension. It was found in many studies that individuals with high blood pressure had lower microbiota diversity compared to healthy control groups. In hypertensive patients, bacteria of the genus Prevotella were mainly found, while in the control group the genus Bacteroidetes predominated. Additionally, a decrease in Faecalibacterium, Roseburia and Bifidobacterium was observed in the hypertensive group. There are several laboratory techniques for the analysis of the intestinal bacterial population, such as 16S rRNA subunit sequencing, whole genome sequencing, and microbiota metagenomics. Despite the fact that the studies conclude that there is a significant relationship between microbiota and hypertension, it is necessary to do more research in different population groups

Identifying patient safety competences among anesthesiology residents: systematic review

Abstract Introduction and objective Patient safety is a concept of great importance to managers, health professionals, and patients and their families, given patient safety promotes more effective care and reduces costs. Moreover, while analyzing the area of anesthesiology, one can realize the epidemiological changes, increased complexity and number of procedures, and the adoption of a new matrix of essential skills mandatory for residents of anesthesiology in Brazil. Thus, it is relevant to identify current patient safety competences among anesthesiology residents. Methods A systematic review was elaborated using PubMed, SciELO, BVS, Cochrane Library, LILACS and CAPES databases with the descriptors "anesthesiology", "patient safety", "residency" and "competence". Results and conclusions Thirteen articles published in the past 10 years were analyzed. The articles depicted competences grouped into three categories: knowledge (identification, prevention and management of adverse events; use of correct and up-to-date information; understanding of human factors; and continuous learning), skills (efficient communication; teamwork; leadership; decision-making; and self-confidence), and attitude (management of stress and fatigue; and infection control). All these skills can be developed and assessed through simulation and active learning methods, profiting from a multidisciplinary approach. Studies also reveal that residents perform poorly in certain patient safety domains due to lack of effective in-depth understanding, appreciation of the topic and ineffective teaching. As a result, greater investment in the topic is needed by teaching and health institutions and researchers.

Update on perioperative hypersensitivity reactions: joint document from the Brazilian Society of Anesthesiology (SBA) and Brazilian Association of Allergy and Immunology (ASBAI) - Part II: etiology and diagnosis / Atualização sobre reações de hipersensibilidade perioperatória: documento conjunto da Sociedade Brasileira de Anestesiologia (SBA) e Associação Brasileira de Alergia e Imunologia (ASBAI) - Parte II: etiologia e diagnóstico

Abstract This second joint document, written by experts from the Brazilian Association of Allergy and Immunology (ASBAI) and Brazilian Society of Anesthesiology (SBA) concerned with perioperative anaphylaxis, aims to review the pathophysiological reaction mechanisms, triggering agents (in adults and children), and the approach for diagnosis during and after an episode of anaphylaxis. As anaphylaxis assessment is extensive, the identification of medications, antiseptics and other substances used at each setting, the comprehensive data documentation, and the use of standardized nomenclature are key points for obtaining more consistent epidemiological information on perioperative anaphylaxis.

Resumo Este segundo documento, escrito por especialistas da Associação Brasileira de Alergia e Imunologia (ASBAI) e da Sociedade Brasileira de Anestesiologia (SBA) interessados no tema anafilaxia perioperatória, tem por objetivo revisar os mecanismos fisiopatológicos, agentes desencadeantes (em adultos e crianças), assim como a abordagem diagnóstica durante e após o episódio. Por se tratar de uma avaliação abrangente, a identificação das medicações, antissépticos e outras substâncias usadas em cada região, registros detalhados, e nomenclatura padronizada são pontos fundamentais para a obtenção de dados epidemiológicos mais fidedignos sobre a anafilaxia perioperatória.

Evaluación clínica y coprológica en sujetos sintomáticos y asintomáticos con infección por Blastocystis spp / Clinical and coprological assessment in symptomatic and asymptomatic subjects with infection with Blastocystis spp

Para evaluar los aspectos morfológicos, clínicos y de laboratorio, en sujetos sintomáticos y asintomáticos con infección por Blastocystis spp. se analizaron 250 muestras fecales de individuos del Hospital Universitario "Antonio Patricio de Alcalá", Cumaná, estado Sucre, previo consentimiento informado. Cada espécimen fecal fue analizado mediante examen directo, la cuantificación del cromista se hizo en diez campos consecutivos de 40X, el análisis morfométrico mediante frotis fecales teñidos con Giemsa observados a 100X, midiendo las estructuras con un micrómetro ocular. Del total de individuos evaluados 32,00% presentó infección por el cromista, 31,25% con monoinfección con más de 5 parásitos por campo de 400X, de los cuales 71,25% de ellos fueron sintomáticos. El morfotipo mayormente identificado fue el de cuerpo central, aunque en una sola muestra de consistencia líquida, se identificó también el de resistencia, hallazgo que no fue posible en el examen directo. En lo concerniente al análisis morfométrico, al evaluar los diámetros de los morfotipos de cuerpo central en pacientes con y sin síntomas, mediante la prueba no paramétrica W Mann-Whitney, se evidenció correspondencia entre ellos (W= 5360,0; p<0,05). El estudio morfológico, la cuantificación del número de parásitos por campo y la utilización de técnicas de tinción complementarias, pueden contribuir a optimizar el diagnóstico de laboratorio.

To evaluate morphological, clinical and laboratory aspects in symptomatic and asymptomatic subjects with Blastocystis spp. 250 faecal samples were analyzed from individuals of the University Hospital "Antonio Patricio de Alcalá", Cumaná, Sucre state, with prior informed consent. Each fecal specimen was analyzed by direct examination, Ritchie and Kinyoun method; The quantification of the chromist was done in ten consecutive 40X fields, the morphometric analysis by fecal smears stained with Giemsa observed at 100X, measuring the structures by an ocular micrometer. Of the total of individuals evaluated 32.00% presented infection by the chromist, 31.25% with monoinfection with more than 5 parasites per field of 400X, of which 71.25% of them were symptomatic. The most identified morphotype was that of the central body, although in a single of liquid consistency, resistance morphotype was also identified, a finding that was not possible in the direct examination. Regarding the morphometric analysis, when evaluating the diameters of the morphotypes of the central body in patients with and without symptoms, by means of the non-parametric W Mann-Whitney test, the correspondence between them was evidenced (W= 5360,0; p<0,05). The morphological study, the quantification of the number of parasites per field and the use of complementary staining techniques, may contribute to optimize the laboratory diagnosis.

Realidad Virtual como Tratamiento para la Fobia Específica a las Arañas: Una Revisión Sistemática / Virtual Reality as a Treatment for Spider Phobia: A Systematic Review

Resumen El creciente interés que ha traído el estudio de las fobias y entre ellas la fobia específica, ha dado lugar al uso diverso de tratamientos, que incluyen la realidad virtual como técnica innovadora. El presente estudio tuvo como objetivo evaluar el impacto de la Realidad Virtual (RV) como tratamiento para la fobia específica a las arañas, a través de una revisión sistemática de investigaciones que hayan sido publicadas en los últimos 10 años (2008 a 2018) en la base de datos Scopus. La revisión sistemática se realizó bajo los lineamientos de la metodología PRISMA. Inicialmente, se identificaron 309 artículos que contaban con los términos de búsqueda en título, resumen y palabras clave, posteriormente, se seleccionaron 109 estudios experimentales ya culminados, se excluyeron otras fobias específicas y otros tipos de tecnologías, siendo seleccionados 10 artículos para análisis a texto completo, incluyendo así solo 5 artículos para la revisión, que usaban la realidad virtual como tratamiento. Acorde a los resultados se encontró evidencia que sugiere que este tipo de intervenciones pueden ser relativamente eficaces para abordar esta problemática, ya que los resultados indican disminución significativa en indicadores clínicos, pero existen también varias limitaciones de orden metodológico. Se espera que esta revisión sistemática promueva investigaciones que usen la realidad virtual como tratamiento para la fobia específica a las arañas, mejorando las limitaciones identificadas en el estudio.

Abstract The growing interest that has brought the study of phobias and among them the specific phobia, has given rise to the diverse use of treatments, which include virtual reality as an innovative technique. The objective of this study was to evaluate the impact of Virtual Reality (VR) as a treatment for spider-specific phobia, through a systematic review of research that has been published in the last 10 years (2008 to 2018) in the Scopus database. The systematic review was carried out under the guidelines of the PRISMA methodology, which were thus excluded; taking into account the search terms in title, summary and keywords, 309 articles were identified, 109 experimental studies were already completed, other specific phobias and other types of technologies were excluded, 10 articles were selected for full-text analysis, including so only 5 articles for the review, which used virtual reality as a treatment. According to the results, evidence was found that suggests that this type of treatment may be relatively effective in addressing this problem, since the results indicate a significant decrease in clinical indicators, but there are also several methodological limitations. It is expected that this systematic review will promote Research that uses virtual reality as a treatment for spider-specific phobia, improving the limitations identified in the study.

Caracterización y efectividad de programas de rehabilitación neuropsicológica de las funciones ejecutivas en pacientes con daño cerebral adquirido: una revisión / europsychological Rehabilitation Treatments of Executive Functions in Patients with Brain Damage: Characterization and Effectiveness A Review

En este artículo se realiza una revisión de los principales programas de rehabilitación de las funciones ejecutivas ampliamente reconocidos en la literatura, así como una recopilación de aquellos estudios que han replicado dichos programas en pacientes con daño cerebral adquirido. Estos estudios son seleccionados a través de PubMed al incluir palabras clave tales como: funciones ejecutivas, daño cerebral, evaluación neuropsicológica e intervención. Luego, se analizan a partir de una organización y división de los componentes que trabajan: solución de problemas y memoria de trabajo, autorregulación, motivación e iniciativa y habilidades metacognitivas. Por último se describen aquellos programas que integran más de dos dominios. De la revisión se concluye que existe una gran cantidad de propuestas para la rehabilitación de estas funciones, y queda claro que la rehabilitación de las funciones ejecutivas ofrece efectos positivos sobre el funcionamiento y calidad de vida de la persona, en especial enfocando la intervención a aquellas áreas personales, familiares y ambientales relevantes para su funcionamiento. Sin embargo, aún se carece de suficientes estudios que demuestren la efectividad y eficiencia de dichos programas, lo cual se explica por el uso de muestras pequeñas o de caso único que no permiten la generalización de resultados, las características heterogéneas de los participantes y la baja generalización a la vida cotidiana.

This paper analyses the effectiveness of rehabilitation programs for executive functions in adults with brain damage. We consider an effective treatment when the program shows results with a statistically significant difference in the neuropsychological assessment after intervention (p < 0.05). Moreover, others criteria were considered such as improvement on daily life scales, the transfer of strategies on daily life conditions and the persistence of these for at least six months. The articles were searched through PubMed and must include keys words as: executive functions, brain damage, neuo-psychological assessment and rehabilitation. Then, they were organised according to which were the aim of the treatment: problem-solving and working memory, self-regulation, motivation and initiative and metacognitive skills. Additionally, there is a section where integrative programs were analysed. We concluded that there are many training programs for executive functions with positive results on patients' daily activities when the intervention is focused in metacognitive skills. However, there are still not enough studies that show an accurate effectiveness due to the conceptual complexity of the executive functions, the variability of patients' symptoms and the limited transfer of the knowledge trained to everyday life.

Preterm newborns at Kangaroo Mother Care: a cohort follow-up from birth to six months / Recién nacidos prematuros asistidos por el Método Canguro: evaluación de una cohorte del nacimiento a los seis meses / Recém-nascidos prematuros assistidos pelo Método Canguru: avaliação de uma coorte do nascimento aos seis meses

To evaluate clinical outcomes, growth and exclusive breastfeeding rates in premature infants assisted by Kangaroo Mother Care at birth, at discharge and at six months of life. METHODS: Prospective study of a premature infants cohort assisted by Kangaroo Mother Care in a tertiary public maternity in Northeast Brazil with birth weight ≤1750g and with clinical conditions for Kangaroo care. RESULTS: The sample was composed by 137 premature infants, being 62.8% female, with average birth weight of 1365±283g, average gestational age of 32±3 weeks and 26.2% were adequate for gestational age. They have been admitted in the Kangaroo Ward with a median of 13 days of life, weighing 1430±167g and, at this time, 57.7% were classified as small for corrected gestational age. They were discharged with 36.8±21.8 days of chronological age, weighing 1780±165g and 67.9% were small for corrected gestational age. At six months of life (n=76), they had an average weight of 5954±971g, and 68.4% presented corrected weight for gestational age between percentiles 15 and 85 of the World Health Organization (WHO) weight curve. Exclusive breastfeeding rate at discharge was 56.2% and, at six months of life, 14.4%. CONCLUSIONS: In the studied sample, almost two thirds of the children assisted by Kangaroo Mother Care were, at six months of life, between percentiles 15 and 85 of the WHO weight curves. The frequency of exclusive breastfeeding at six months was low...

Intrachromosomal amplification of chromosome 21 (iAMP21) detected by ETV6/RUNX1 FISH screening in childhood acute lymphoblastic leukemia: a case report

Chromosome abnormalities that usually define high-risk acute lymphoblastic leukemia are the t(9;22)/ breakpoint cluster region protein-Abelson murine leukemia viral oncogene homolog 1, hypodiploid with < 44 chromosomes and 11q23/ myeloid/lymphoid leukemia gene rearrangements. The spectrum of acute lymphoblastic leukemia genetic abnormalities is nevertheless rapidly expanding. Therefore, newly described chromosomal aberrations are likely to have an impact on clinical care in the near future. Recently, the rare intrachromosomal amplification of chromosome 21 started to be considered a high-risk chromosomal abnormality. It occurs in approximately 2-5% of pediatric patients with B-cell precursor acute lymphoblastic leukemia. This abnormality is associated with a poor outcome. Hence, an accurate detection of this abnormality is expected to become very important in the choice of appropriate therapy. In this work the clinical and molecular cytogenetic evaluation by fluorescence in situ hybridization of a child with B-cell precursor acute lymphoblastic leukemia presenting the rare intrachromosomal amplification of chromosome 21 is described.

Ultrassonografia abdominal pré-operatória em cães e gatos com suspeita de tumores abdominais / Preoperative Abdominal Ultrasonography in dogs and cats with suspected abdominal tumors

Objetivou-se com este estudo analisar a acurácia do exame ultrassonográfico na definição da origem de neoplasias abdominais e avaliar a eficiência da técnica em sugerir a malignidade do processo. Em 24 pacientes de 113 animais avaliados pelo exame ultrassonográfico, foi observado massa e/ou entremeado nodular em diferentes órgãos da cavidade abdominal, classificados em tipo I, II, II(+) e III. Compararam-se os achados ultrassonográficos com a cirurgia e o exame histopatológico. A determinação da origem da massa foi correta em 20 (83 por cento) animais. Pelos dados estatísticos de acurácia de 91,67 por cento obtidos, acredita-se que o exame ultrassonográfico é interessante para se determinar previamente a malignidade, principalmente naqueles pacientes que apresentam lesões agressivas.

The aim of this study was evaluate efficacy of the ultrassonographic exam in the defining the location of the abdominal neoplasm and to estimate the accuracy of the method in screening the malignant neoplasm process. In 24 patients of 113 animals evaluated by the ultrassonographic exam it was observed a mass and/or a intermingled nodule in different organs in the abdominal cave, classified as type I, II, II(+) e III. It was compared the sonographic findings with surgical and histopathological analysis. The determination of the mass origin was correct in 20 (83 percent) animals and the percentage accuracy of malignant ultrasound determination was 91.67 percent. So, it is believed that the ultrasound is interesting to determine the malignancy in advanced cases, especially in those patients who have aggressive lesions.

Anatomia ultrassonográfica dos linfonodos abdominais de furões europeus hígidos / Ultrasonographic anatomy of abdominal lymph nodes in the normal ferret

Nos últimos anos o furão (Mustela putorius furo) tornou-se um conhecido animal de estimação sendo observada uma população em constante crescimento no Brasil, e por conseqüência cada vez mais presente em clínicas veterinárias. O presente trabalho teve como objetivo avaliar a anatomia ultrassonográfica dos linfonodos abdominais de furões-europeus hígidos. Foram utilizados 20 animais, dentre os quais nove eram machos e onze fêmeas, com idade média total de três anos. Localizaram-se em 100 por cento dos furões os linfonodos mesentéricos, em 55 por cento dos animais os linfonodos pancreático-duodenal e esplênico, em 20 por cento o linfonodo gástrico e em 5 por cento o linfonodo hepático. Conclui-se que a localização e características ultrassonográfica dos linfonodos abdominais em furões são muito similares aos linfonodos abdominais de gatos, sendo este estudo uma orientação preliminar para a localização dos linfonodos abdominais de furões hígidos.

In recent years the ferret (Mustela putorius furo) has become popular pet featuring a ever growing population in Brazil, and being increasingly found in veterinary clinics. This study aimed to evaluate the ultrasound anatomy of abdominal lymph nodes of healthy ferrets. We used 20 animals, nine of which males and eleven females, with overall mean age of three years. We located the mesenteric lymph nodes in 100 percent of the ferrets, the pancreatic-duodenal lymph nodes and the splenic ones in 55 percent, the gastric lymph node in 20 percent, and the hepatic lymph node in 5 percent. We measured their lengths. It is concluded that the location and sonographic characteristics of the abdominal lymph nodes in ferrets are very similar to the abdominal lymph nodes of cats. This is a preliminary orientation for the location of abdominal lymph nodes of healthy ferrets.

Instrumentos de evaluación de funcionalidad en niños con discapacidad: una comparación descriptiva entre The Functional Independence Measure for Children (WeeFIM) y The Pediatric Evaluation of Disability Inventory (PEDI) / Functional assessments in children with disabilities: a comparative description betweeen Functional Independence Measure for Children (WeeFIM) and The Pediatric Evaluation of Disability Inventory (PEDI)

Nowadays there are different alternatives to assess functionality in children with disabilities. The Functional Independence Measure for Children (WeeFIM) and the Pediatric Evaluation of Disability Inventory (PEDI) are two of the most widely used instruments. There is no consensus on which of them is preferable to use, therefore it is necessary to compare both tools, considering the Chilean reality and the characteristics of the Teletón Institute of Santiago. The aim of this descriptive comparison is to address this question and pose a possible answer to it.

Hoy en día existen diferentes escalas de evaluación funcional para niños con discapacidad. The functional Independence Measure for Children (WeeFIM) y The Pediatric Evaluation of Disability Inventory (PEDI) son alternativas utilizadas mas ampliamente. No existe consenso sobre cuál de ellas es preferible usar, por lo que es necesario comparar ambas herramientas en el contexto de la realidad chilena y considerando las características del Instituto de Rehabilitación Infantil Teletón de Santiago. La presente comparación descriptiva pretende abordar esta incógnita y plantear posibles respuestas a ésta.

Caloric density of Loricariichthys platymetopon (Osteichthyes, Loricariidae) in the Upper Paraná River floodplain, Brazil

This study analyzed the muscle energy content (caloric density) of L. platymetopon captured at different sites of the Upper Paraná River floodplain, and potential relationships between the content and various environmental variables (water temperature, oxygen dissolved in water, food availability, relative numeric abundance) and biological variables (body size and reproductive cycle). Quarterly samplings from September 2006 to June 2007 in the lakes and rivers resulted in a sample of 739 specimens, whose muscle caloric density was determined using a calorimeter. Differences between the caloric averages of the males and females and among the different stages of gonadal development were not significant. Caloric density varied over time and space, with two seasonal variation trends. The intensity of the correlation between the caloric density and each environmental variable, as well as the type of correlation, varied according to the sampled site. Body size and reproductive cycle were not correlated with caloric density.

Este estudo analisou o conteúdo de energia (densidade calórica) de L. platymetopon capturados em diferentes locais da planície alagável do Alto Rio Paraná, e potenciais relações entre este conteúdo e várias variáveis ambientais (temperatura da água, oxigênio dissolvido na água, disponibilidade de alimento, abundância relativa numérica) e variáveis biológicas (tamanho corpóreo e ciclo reprodutivo). Coletas trimestrais, de setembro/2006 a junho/2007, em lagos e rios, resultaram em uma amostra de 739 espécimes, cuja densidade calórica muscular foi determinada através de calorímetro. Diferenças entre as médias calóricas de machos e fêmeas e entre os estádios de desenvolvimento gonadal não foram significativas Densidade calórica variou sazonal e espacialmente, com duas tendências de variação sazonal. A intensidade da correlação entre densidade calórica e cada variável e cada variável ambiental, assim como, a forma de correlação, variou de acordo com o local amostrado. Tamanho corpóreo e ciclo reprodutivo não estiveram correlacionados à densidade calórica.

Avaliação ultrassonográfica do meato acústico em cães / Ultrasonographic evaluation of the external ear in dogs

O propósito deste trabalho foi determinar a viabilidade da ultrassonografia para avaliar o canal auditivo externo de cães, aferindo a espessura e arquitetura da parede do conduto auditivo e bula timpânica. Foram avaliados 10 cães da raça Retriever do Labrador não portadores de otite externa. O exame foi realizado com o aparelho de ultrassonografia bidimensional e transdutor linear de 14 MHz, com todos os animais sob efeito de anestesia geral. O exame foi efetivado antes e depois do conduto ser preenchido com solução salina, promovendo uma janela acústica anecóica. A artéria maxilar foi identificada com o Doppler colorido o que facilitou a localização da bula timpânica em todos os cães. A definição da imagem da parede proximal ao transdutor foi pior quando comparada à parede distal em todos os animais, isto devido à proximidade da parede com a face de leitura do transdutor. Nos cães que apresentavam uma maior quantidade de cerúmen a superfície do epitélio estava com uma camada hiperecóica mais evidente. A membrana timpânica não foi identificada em nenhum animal. Conclui-se que ultrassonografia é viável e deve ser mais pesquisada na contribuição diagnóstica das doenças óticas em cães.

The purpose of this study was to determine the viability of ultrasonographic evaluation of the external ear in dogs. The thickness and architecture of the ear wall and tympanic bulla of 10 Labrador Retrievers without ear disease was evaluated. The examination was performed with an ultrasound system and a 14 MHz bidimentional linear-array transducer and general anesthesia, before and after the infusion of saline solution into the ear canal. The maxillary artery was identified with color Doppler and helped to establish the location of the tympanic bulla in all dogs. The proximal wall was less well-defined when compared with the distal wall of the ear canal. Dogs with increased ceruminal content within the ear canal showed a hypoechoic epithelium. The tympanic membrane was not identified. It was concluded that ultrasound evaluation is feasible and needs to be explored as clinical diagnostic tool for the diagnosis of ear diseases in dogs.

Variation in energy density of Loricariichthys platymetopon (Siluriformes: Loricariidae) in the upper Paraná River basin

The present study described the variations in energy density from skeletal muscles of Loricariichthys platymetopon in relation to body size, sex, gonadal development stages, sampling site and habitat type (lotic, semi-lotic and lotic). Samplings were performed between June 2002 and August 2006 in points located in the upper Paraná River floodplain, Rosana Reservoir and Diamante Stream. The energy density from each muscle sample of 212 specimens was determined using an adiabatic calorimeter. The correlations between the variables 'muscle energy density' and 'specimen standard length' were not significant. Only in the Rosana Reservoir there was a significant difference in energetic means between 'sex'. Otherwise, due to the gonadal development stage, a significant difference between energetic means was recorded only for males from the upper Paraná River floodplain and for both sexes in Rosana Reservoir. The density of muscle energy ranged from 4,170 to 5,540 cal/g DW (dry weight), with the means (± standard deviation) of 5,140± 0.06 cal/g DW in the Reservoir, 4,950±0.25 cal/g DW in the stream and 4,920 ±0.18 cal/g DW in the floodplain. Furthermore, we also detected a significant difference between the energy means from the different sampled sites, but the same was not registered among the analyzed habitats. In conclusion, the variation in muscle energy density from L. platymetopon may occur. The occurrence of variation between the sexes depends on the site, and the density variation among the stages depends on both the site and 'sex'. In summary, the spatial variation in muscle energy density from this species strengthens the idea that this factor is not a constant parameter, so it should not be applied in bioenergetics modeling and in the quantification of energetic balance as an unique value.

O presente estudo objetivou descrever as variações na densidade de energia dos músculos estriados esqueléticos de Loricariichthys platymetopon em relação aos fatores tamanho, sexo, estádio de desenvolvimento gonadal, local e tipo de habitat (lótico, semi-lótico e lótico). As amostragens foram realizadas entre junho de 2002 e agosto de 2006 em pontos localizados na planície alagável do alto rio Paraná, no reservatório de Rosana e no ribeirão Diamante. A densidade de energia de cada amostra de músculo de 212 espécimes de L. platymetopon foi determinada utilizando-se bomba calorimétrica. As correlações entre as variáveis 'densidade de energia muscular' e 'comprimento padrão do espécime' não foram significativas. Diferença significativa entre as médias energéticas foi registrada entre 'sexo' apenas no reservatório de Rosana. Diferença nas médias energéticas, devido ao estádio de desenvolvimento gonadal, foi significativa somente para machos na planície alagável do alto rio Paraná e para ambos os sexos no reservatório de Rosana. A densidade de energia muscular variou de 4.170 a 5.540 cal/g PS (peso seco), sendo as médias (± desvio-padrão) igual a 5.140± 0,06 cal/g PS no reservatório, 4.950±0,25 cal/g PS no ribeirão e 4.920 ±0,18 cal/ g PS na planície. Foi encontrada diferença significativa entre as médias de energia dos diferentes locais amostrados, entretanto, o mesmo não foi registrado nos habitats analisados. Conclui-se que pode ocorrer variação na densidade de energia muscular de L. platymetopon. A ocorrência de variação entre os sexos depende do local de coleta, e a variação na densidade entre os estádios depende tanto do local quanto do 'sexo'. A variação espacial na densidade de energia muscular desta espécie reforça a idéia de que a mesma não é um parâmetro invariável e que por isso não deve ser aplicada na modelagem bioenergética e na quantificação do balanço energético como um valor único.
