Percurso e resultados da terapia fonoaudiológica na síndrome de Prader-Willi (SPW): relato de caso

O objetivo deste estudo foi descrever o percurso e os resultados da terapia fonoaudiológica na síndrome de Prader-Willi, por meio do estudo longitudinal do caso de uma criança de 8 anos de idade, do gênero masculino, ao longo de quatro anos de terapia fonoaudiológica em uma clínica-escola. Foram realizadas filmagens de sessões de terapia e análise documental de informações dos prontuários referentes à anamnese, avaliação e relatórios terapêuticos fonoaudiológicos e avaliações multidisciplinares. A criança apresentou características típicas da síndrome de Prader-Willi como obesidade, hiperfagia, ansiedade, problemas de comportamento e auto-agressões. em avaliação fonoaudiológica foram observados hipotonia orofacial, sialorréia, voz hipernasal, alterações cognitivas, dificuldades de compreensão oral, comunicação por meio de gestos e produção de palavras isoladas ininteligíveis. Inicialmente, a terapia fonoaudiológica teve o objetivo principal de promover o desenvolvimento da linguagem com ênfase na interação social por meio de atividades lúdicas. Com a evolução do caso o direcionamento principal passou a ser o desenvolvimento de habilidades conversacionais e narrativas. Foram observadas evoluções quanto à manutenção da atenção, brincadeira simbólica, contato social e comportamento. Além disso, houve aumento do vocabulário, evolução quanto à compreensão oral e desenvolvimento de habilidades narrativas. Dessa maneira, a intervenção fonoaudiológica em caso de síndrome de Prader-Willi foi eficaz em diferentes níveis, no que se refere às habilidades fonológicas, sintáticas, lexicais e pragmáticas da linguagem

Isolamento e caracterização de candida albicans e outras leveduras de águas de recreação não marinha e de materiais clínicos

Candida albicans and other yeasts from recreational water or clinical materials were isolated. Sixty-six water samples, originating from eight swimming pools and five lakes with beaches were examined for the presence of these yeasts, by a membrane filter method and 'pour plate' technique. Sixty-two clinical materials from suspected cases of candidiasis were studied in the same period. Rhodotorula sp and C. albicans were more frequently isolated from lakes and swimming pools, respectively; C. albicans and C. parapsilosis from clinical materials. From 44 samples of C. albicans, 90,9% were serotype A, and 9,1%, serotype B; C. albicans from recreational waters belong only serotype A. No difference was observed in the M.I.C. of C. albicans strains from waters and clinical materials. All strains were susceptible to the antifungal drugs tested.

Transforming open mining pits into fish farms: Moving towards sustainability

The legacy of mining activities has typically been land 'returned to wildlife', or, at some sites, degraded to such an extent that it is unsuitable for any alternate use. Progress towards sustainability is made when value is added in terms of the ecological, social and economic well-being of the community. In keeping with the principles of sustainable development, the innovative use of flooded open pits and tailings impoundments as commercial, recreational or ornamental fish farms should be considered in some locations, as it could make a significant contribution to the social equity, economic vitality and environmental integrity of mining communities. This article highlights the growing significance of aquaculture and explores the benefits and barriers to transforming flooded pits and impoundments into aquaculture operations. Among other benefits, aquaculture may provide a much-needed source of revenue, employment and, in some cases, food to communities impacted by mine closure. Further, aquaculture in a controlled closed environment may be more acceptable to critics of fish farming who are concerned about fish escapes and viral transmissions to wild populations. Despite the potential benefits, aquaculture in flooded pits and impoundments is not without its complications - it requires a site-specific design approach that must consider issues ranging from metals uptake by fish, to the long-term viability of the aquatic system as fish habitat, to the overall contribution of aquaculture to sustainability. © 2004 United Nations.

Plesiomonas shigelloides: Um enteropatógeno emergente?

Plesiomonas shigelloides is a Gram-negative rod-shaped bacterium, of the family Enterobacteriaceae, which has been isolated from freshwater and salt water, freshwater fish, shellfish and many species of animals. Most human P. shigelloides infections are suspected to be waterborne. The organism can be found in untreated water used as drinking water, in recreational water, or in water used to rinse food that is consumed without cooking or heating. The ingestion of P. shigelloides does not always cause illness in the host animal, and the organism may be present temporarily as a transient, noninfectious member of the intestinal flora. It has been isolated from the stools of patients with diarrhea,but it is also sometimes isolated from healthy individuals. P. shigelloides has been implicated in gastroenteritis, usually a self-limiting disease characterized by fever, chills, abdominal pain, nausea, diarrhea or vomiting; in severe cases the diarrhea may be yellowish-green, foamy and tinged with blood. The bacteria may also cause extra-intestinal infection. Furthermore, it can produce toxins and may be invasive. The evidence in favor of considering P. shigelloides as an enteropathogen is not totally convincing. Although it has been isolated from patients with diarrhea and incriminated in some outbreaks involving contaminated water and food, it was not possible, in many P. shigelloides samples associated with gastrointestinal infections, to identify a definite mechanism of virulence.

Diversidade de microrganismos indicadores utilizados na avaliação da contaminação fecal de areias de praias recreacionais marinhas: Estado atual do conhecimento e perspectivas

Although the quality of sea recreational waters is already monitored by programs implanted in some Brazilian states, including the State São Paulo, little attention has been given to beach sands, which have been disregarded from the point of view of public health. However, this panorama is changing in recent years due to an increasing number of cases of mycoses and bacterial infections affecting people who frequent beaches and use sands as recreation places. This has caused greater concerns with the contamination of this environment, also measurable by the increase of the number of scientific works on sediments and recreational beach sands microbiota. Currently one knows that in general these sediments contain more microorganisms than the water and are therefore potential sources of contamination of human beings by pathogenic microorganisms. The results of works carried through in some countries are worrying, and have demonstrated the necessity of establishing standards and limits so that monitoring programs of the microbiological quality of beach sands are implanted. Such concern is especially high in Brazil, a country of a tropical climate where thousands of beaches, used for recreation, extend for almost eight thousand kilometers of the coast. In the context of Baixada Santista, studies carried through have shown that in certain situations beach sands can contain more microorganisms than waters and may be a risk to the health of users.

Densidade de Enterococcus sp em águas recreacionais e areias de praias do município de São Vicente-SP, Brasil e sua relação com parâmetros abióticos

Coastal cities attract a large number of tourists for their beautiful landscape and recreational activities, increasing the municipalities' income source. Thus, a need is clear for the establishment of beach quality monitoring programs to ensure bathers health. Although there is an effective monitoring program for recreational waters in Brazil there are no programs to certify the quality of beach sands. In this sense, the aim of this work was to analyze the density of bacteria from the genus Enterococcus in both sand and water from two beaches from São Vicente, São Paulo (Brazil) and correlate these densities to abiotic parameters such as: temperature, salinity, particle size, organic matter and tides). Water and sand samples were collected during February 2006 on the beaches of Gonzaguinha e Ilha Porchat and bacterial densities were determined by membrane filter technique. Temperature and salinity were measured in situ with a thermometer and a refractometer while particle size and organic matter were determined according to methods described by Suguio and Dean. There were significant differences between densities found in water and sand (p=0.004), being approximately 20 times higher in Gonzaguinha's beach sands. Similar results were found for Ilha Porchat beach samples, being the densities found in sand 3 times greater than those found in water. Both beaches showed a negative correlation between bacterial densities and salinity and temperature, suggesting a deleterious effect of these parameters on the bacterial community. On the other hand, no correlation was found between organic matter and particle size and bacterial densities. This work demonstrates that there is a great necessity for monitoring beach sand since the evaluation of beach quality is an important part of integrated coastal management programs.

Parâmetros físico-químicos da água e ocorrência de streptococcus spp. em criação intensiva de tilápia no estado do espírito Santo, Brasil

This study evaluated the influence of intensive farming of tilapia on physical and chemical parameters and on the occurrence of Streptococcus spp. in the water of the lake and of cages. Throughout a year, monthly samplings were taken in the rainy and dry seasons for a year, at two sampling sites, lake and net cages. For the determination of water quality, physical and chemical water parameters were evaluated and compared to the standards established by Conama Resolution no. 357/2005. The presence of Streptococcus spp. in the water was determined by plating on blood Agar and biochemical screening. Mean values of water parameters were tested using the Kruskal-Wallis test comparing sampling sites and seasons. Ammoniacal nitrogen (ammoniacal-N), total phosphorus (total-P) levels and occurrence of Streptococcus spp. have increased in the water of the net cages. The mean values of several parameters have decreased during the rainy period, except for pH, temperature and ammoniacal-N. Total-P and dissolved oxygen levels, during dry and rainy periods, respectively, exceeded the standard established for freshwater class 2, recommended for aquaculture, which can be harmful to the fish. Therefore, constant monitoring of the physical,chemical and microbiological water parameters is recommended since the Juara lake is also used for recreational purposes.
