Partial external mitral annuloplasty in dogs with myxomatous mitral valve degeneration and congestive heart failure: Outcome in 9 cases

Objective: To report the outcome of partial external mitral annuloplasty in dogs with congestive heart failure (CHF) due to mitral regurgitation caused by myxomatous mitral valve degeneration (MMVD). Animals, materials and methods: Nine client-owned dogs with CHF due to mitral regurgitation caused by MMVD. Surgery consisted of a double row of pledget-butressed continuous suture lines placed into the left ventricle parallel and just ventral to the atrioventricular groove between the subsinuosal branch of the left circumflex coronary artery and the paraconal branch of the left coronary artery. Results: Two dogs died during surgery because of severe hemorrhage. Two dogs died 12 and 36 h after surgery because of acute myocardial infarction. Three dogs were euthanized 2 and 4 weeks after surgery because of progression of CHF, 1 was euthanized 30 days after surgery for non-cardiac disease, and 1 survived for 48 months. In the 5 dogs that survived to discharge there was no significant change in the left atrium to aortic ratio with surgery (3.6 ± 0.56 before surgery; 3.1 ± 0.4 after surgery; p = 0.182), and no significant change in mitral regurgitant fraction in 4 dogs in which this measurement was made (78.7 ± 2.0% before surgery; 68.7 ± 7.5% after surgery; p = 0.09). Conclusions: Partial external mitral annuloplasty in dogs with CHF due to MMVD was associated with high perioperative mortality and most dogs that survived to discharge failed to show clinically relevant palliation from this procedure. Consequently, partial external mitral annuloplasty is not a viable option for dogs with mitral regurgitation due to MMVD that has progressed to the stage of CHF. © 2011 Elsevier B.V.

A sound education: Becoming aware of the sound around us

In this article it is intended to discuss the issue of noise pollution from an unusual point of view: noise pollution is not only the result of sound increase worldwide, but, particularly, the poor quality of our listening habits in modern life as well. In contemporary society we are subject to a considerable amount of stimulus to all our senses: vision, scent, taste and hearing which are becoming more and more insensible due to over exposure in our environment. These increased stimuli make us look for alternatives to reduce our ability to perceive them and be protected from injuries. However, our sensitivity will also decrease. In the specific case of environment noise, over exposure has made us forget the enchantment of certain sounds that used to give us pleasure or evoke good feelings by many ways, making us recall certain good things, bringing particular moments of our lives to our memory or even filling us with strong emotion. The Canadian composer and music educator, R. Murray Schafer, believes that noise pollution is the result of a society who became deaf. Closing our ears to noise protect us from noise pollution but also prevent us from grasping subtleties of listening. Contemporary world does not help us to be aware of sound in the space around us; acquiring this hearing ability is a matter of focus, interest and practice. Sound education exercises are aimed at children, teenagers and adults who want to improve their listening ability to environmental sounds, perceive its proprieties and learn how sound affects us and touches our feelings. The results are easy to accomplish and contribute to our awareness of the sound environment around us and to the conception of the environmental sound as a composition made by everybody and everything through positive actions, strong will and high sensitivity.

Rights of urban children

Urban children in Latin AmericaThis issue of Challenges addresses a topic deserving of special attention: the high proportion of children and adolescents in the region's urban areas who live in precarious conditions. Their disparate living conditions are examined with a look at the moderate deprivation (housing deficiencies, monetary poverty or low level of education) and severe deprivation (a combination of two or more of the aforementioned deficits) affecting urban dwellers. It is estimated that about 29.0% of children and adolescents in these areas live in conditions of severe deprivation and 27.6% experience moderate deprivation for an average of eight countries.In severely deprived rural and urban areas a higher proportion of children are not immunized against measles, and a greater percentage of adolescents are neither studying nor economically active, and are already parents.These disparities call for differentiated policies with a strong local focus and the potential to improve living conditions, lower the risk of infant morbidity and mortality, and reduce rates of adolescent pregnancy and school dropout. Significant initiatives and policies designed to produce healthy and inclusive environments have already been put in place in some of the most vulnerable areaswith a view to improving the quality of life among these groups.In addition to the featured article, the issue includes information on relevant meetings and conferences held in the region over the year, children's and adolescents' testimonies, and expert opinion.

The Rights of Indigenous Children

While children in general are overrepresented among those living in poverty, a long history of discrimination and exclusion has ensured that indigenous children in Latin America and the Caribbean are in an even worse position. In the general population 63% of children aged under 18 years live in poverty, as measured by privation of the basic rights to well-being; however, that figure is as high as 88% among indigenous children in the same age group. This is a violation of these children's rights —including their rights to survival and development— and entails high costs for society in terms of productive capacity and social inclusion. That is the thrust of the argument in the central article of this issue of Challenges, which focuses on poverty among indigenous children. The data show a pattern of inequality that is highly detrimental to indigenous children: they make up a disproportionate number of those living in extreme poverty and are three times more likely to lack access to education, safe drinking water and housing than other children. It is a matter of particular concern that in the countries of the Andean Community 5 of every 10 indigenous children under the age of 5 years suffer from chronic malnutrition.This edition includes brief testimonies by indigenous children as to what their life is like; an interview with Marta Maurás, Vice-Chairperson of the United Nations Committee on the Rights of the Child, on the international mechanisms in place to safeguard the rights of indigenous children; and, lastly, an article on the Uantakua programme in Mexico, which uses information and communication technologies in bilingual schools with large indigenous populations.
