Ultrassonografia torácica extracardíaca em pequenos animais

Until recently, ultrasonography was not considered one of the prevailing imaging methods for thoracic evaluation due to its limitations in evaluating lesions located below thoracic gas collections in individuals with normal lung tissue as well as in those with pneumothorax. Nevertheless, ultrasound has an advantage over other imaging techniques. It allows not only differentiating pleural from pulmonary lesions, but also identifying and assessing peripheral pulmonary lesions. Thus, thoracic ultrasound has become more popular in Veterinary Medicine as an ancillary method in the diagnosis and treatment of several diseases of the thoracic cavity, especially in emergency settings. This review aims at providing information on the main alterations found in the chest wall, mediastinum, pleura, lung and diaphragm by means of ultrasonography.

Congenital diaphragmatic Bochdaleck hernia: Case report

Congenital diaphragmatic Bochdaleck hernia is an anatomical defect of the diaphragm, which allows protrusion of abdominal viscera into the chest, causing serious pulmonary and cardiac complications in the neonate. In this study we aimed to present a case of congenital Bochdaleck hernia. We investigated a 40 weeks old child, with a pregnancy carried out in a public hospital in Passo Fundo, Rio Grande do Sul, Brazil. We suggest that if diagnosis occurs in the prenatal period, the prognosis of this disease improves. As a consequence, it allows the parity of the fetus to occur in a higher complexity center, optimizing the chances of survival. © 2012 Lava et al.; licensee BioMed Central Ltd.

Morphological and Genomic Differences Between Cutting and Racing Lines of Quarter Horses

To investigate morphological and genomic differences between cutting and racing lines of Quarter Horses, 120 racing and 68 cutting animals of both sexes, registered at the Brazilian Association of Quarter Horse Breeders, were used. Blood samples were collected, and the following physical traits were measured: weight; height at withers; body length; length of the shank, pastern, rump, head, and neck; and chest, shank, and hoof circumference. For analysis of genomic differences, 54,602 single-nucleotide polymorphisms (SNPs) were genotyped using the Equine SNP50 BeadChip, and the quality of individual and SNP genotype data were evaluated. The fixation index, FST, was used to identify genome regions that were altered in the lines by selection. The results showed significant differences between the lines in all physical traits. Quality control led to the exclusion of four cutting animals with a call rate of <0.95. After filtering, 12,544, 13,815, and 13,370 SNPs were excluded for the whole population (n = 184), the 120 racing animals, and the 64 cutting animals, respectively. The number of informative polymorphisms detected in each line and in the whole population indicated that the Equine SNP50 BeadChip can be used in genetic studies of Quarter Horses. The fixation index, FST, identified 2,558 genome regions that may have been modified by divergent selection. © 2013 Elsevier Inc.

Overall and differentiated session ratings of perceived exertion at different time points following a circuit weight training workout

Session ratings of perceived exertion (SRPE) have been considered to provide a quantitative evaluation of the entire exercise session in different types of resistance training. In this study we investigated the ability of SRPE to assess exercise strain in a circuit weight training (CWT) workout and the influence of time lag to report SRPE. Ten healthy male volunteers (22.3±2.8 years, 72.5±6.5kg, and 175±5cm) completed a CWT session involving three circuits of five multiple joint exercises with single sets of 20 repetitions at 30% one repetition maximum (1-RM). Heart rate [63.7-75.0% maximum heart rate (%HRmax)], blood lactate (5.6-7.6mM) as well as overall, chest, and active muscle RPE increased significantly (p<0.05) throughout the CWT, but no significant differences were found between ratings of perceived exertion (RPE) types. Overall, chest and active muscle SRPE were accessed 10 minutes, 20 minutes, and 30 minutes after the workout, with no significant main effects or SRPE type×time interaction being found (p>0.05). Finally, no significant differences (p>0.05) were observed between averaged SRPE and RPE responses (overall: 3.7±0.6 vs. 3.5±0.9; chest: 3.8±0.7 vs. 3.6±0.8; active muscle; 3.7±0.7 vs. 3.5±0.7). These results suggest SRPE, irrespective of the moment at which it is taken, to be a useful tool for assessing global exercise strain in a CWT workout, providing coaches, physicians, and exercisers a practical way for monitoring this type of resistance training. © 2013.

Enfisema lobar congênito: série de casos de 30 anos em dois hospitais universitários

Objetivo: Revisar os casos de enfisema lobar congênito (ELC) operados nos últimos 30 anos em dois hospitais universitários. Métodos: Foram revistos os prontuários médicos das crianças com ELC operadas no Hospital das Clínicas da Faculdade de Medicina de Botucatu e no Hospital da Universidade de Mogi das Cruzes entre 1979 e 2009. Dados sobre sintomas, exame físico, achados radiológicos, diagnóstico, tratamento cirúrgico e seguimento pós-operatório mediato e tardio foram analisados. Resultados: Durante o período estudado, 20 crianças com ELC foram submetidas a tratamento cirúrgico. A média de idade dos pacientes no momento da cirurgia foi 6,9 meses (variação, 9 dias a 4 anos). Todos os casos apresentaram sintomas ao nascimento ou nos primeiros meses de vida. Em todos os casos, a radiografia simples de tórax foi importante na definição do diagnóstico. Em casos de dificuldade respiratória moderada, a TC de tórax auxiliou no diagnóstico. Um paciente com desconforto respiratório grave foi diagnosticado erroneamente com pneumotórax hipertensivo e submetido a drenagem torácica. A broncoscopia só foi realizada nos pacientes com dificuldade respiratória moderada e não foram encontrados sinais de anomalias traqueobrônquicas. A abordagem cirúrgica foi realizada através de toracotomia lateral poupadora de músculo. O lobo superior esquerdo e o lobo médio foram os mais afetados, seguidos pelo lobo superior direito. A lobectomia foi realizada em 18 casos, enquanto a bilobectomia foi realizada em 2 casos (com ressecção de cisto broncogênico em 1 desses). Complicações pós-operatórias não foram observadas. O acompanhamento pós-operatório foi de pelo menos 24 meses (média, 60 meses) e não foram observadas complicações tardias nesta série. Conclusões: O ELC é uma doença pouco comum, ainda negligenciada, de etiologia incerta, mas de fácil diagnóstico radiológico e tratamento cirúrgico eficaz.

Cloreto de sódio a 0,9%, adicionado ou não de dexametasona, intrapleural, na prevenção de aderências pulmonares após toracotomia intercostal em cães

Pulmonary adhesions in dogs are a common sequel after surgical intervention, undermining any interventions. This study aimed to determine in dogs, the efficacy of sodium chloride solution 0.9% with or without dexamethasone in order to prevent adhesions after intercostal thoracotomy. Fifteen dogs were separated into three groups of five animals, A, B and C and underwent thoracotomy in the fifth left intercostal space. Three other dogs were submitted to a previous study. In the dogs of Group A it was performed only a thoracotomy and thoracorraphy; in group B, it was performed a thoracotomy, thoracorraphy and injection into the pleural cavity of isotonic sodium chloride (10ml) and dexamethasone (1mg kg-1). In the dogs of the group C, it was performed the thoracotomy thoracorraphy and injected isotonic sodium chloride (10ml kg-1) into the pleural cavity. After 15 days of thoracotomy, it was performed transdiaphragmatic thoracocospy to determine the presence and score of adhesions between the lung and chest wall. The results demonstrated the presence of adhesions in the majority of group A and reduced or no adhesions in the other groups. For statistical evaluation, it was pplied the chi-square test with significance level of 5% (P≤0.05). The sodium chloride solution 0.9% with or without dexamethasone in the pleural space prevented or reduced lung adhesions after intercostal thoracotomy.

Frequency of estrus in santa inês, texel and ile de france ewes in the northwest of Paraná state, Brazil

The incidence of estrus in nulliparous Santa Inês (n = 16), Texel (n = 16) and Ile de France (n = 15) ewes fed two levels of crude protein (CP, 12 or 16%) was monitored from July 2005 to December 2006, and seasonality in the Santa Inês breed in the south of Brazil was characterized. The solar radiation data were recorded daily, and samples of blood were collected biweekly for determination of the plasma concentration of progesterone in Santa Inês lambs at, on average, 11±1 months of age. The female Santa Inês lambs, in the experimental period, stayed among teaser rams with a powdered-dye-ink mixture placed on their chest to mark the females that accepted to be mounted. Santa Inês ewes did not manifest estrus in the firstfortnightofNovemberandinDecember2005,norinthelastfortnightofDecember2006.Estrusactivitywasnotobservedon any of the three breeds in October 2006. Breeds differed at the level of 12% CP. Santa Inês and Ile de France females did not differ as for the probability estrus manifestation and both presented higher probabilities then Texel. When the effect of 12 or 16% CP on each breed was evaluated separately, it was verifiedthatlevelsof12or16%ofcrudeproteindidnotchangethe probability of estrus manifestation in any of the studied breeds. The concentration of plasma progesterone inSanta Inês ewes during the spring of 2005 and 2006 indicated that there is difference between 12% CP (0.68±1.32 ng/mL) and 16% CP (1.28±1.99 ng/mL) and between the years 2005 (0.39±0.78 ng/mL) and 2006 (1.47±2.08 ng/mL), demonstrating the anestrous seasonality of Santa Inês in South Brazil. © 2013 Sociedade Brasileira de Zootecnia.
