A gestão dos resíduos hospitalares e o papel da autoridade de saúde : caso do concelho da Amad

RESUMO O Problema. A natureza, diversidade e perigosidade dos resíduos hospitalares (RH) exige procedimentos específicos na sua gestão. A sua produção depende do número de unidades de prestação de cuidados de saúde (upcs), tipo de cuidados prestados, número de doentes observados, práticas dos profissionais e dos órgãos de gestão das upcs, inovação tecnológica, entre outros. A gestão integrada de RH tem evoluído qualitativamente nos últimos anos. Existe uma carência de informação sobre os quantitativos de RH produzidos nas upcs e na prestação de cuidados domiciliários, em Portugal. Por outro lado, os Serviços de Saúde Pública, abrangendo o poder de Autoridade de Saúde, intervêm na gestão do risco para a saúde e o ambiente associado à produção de RH, necessitando de indicadores para a sua monitorização. O quadro legal de um país nesta matéria estabelece a estratégia de gestão destes resíduos, a qual é condicionada pela classificação e definição de RH por si adoptadas. Objectivos e Metodologias. O presente estudo pretende: quantificar a produção de RH resultantes da prestação de cuidados de saúde, em seres humanos e animais nas upcs, do sistema público e privado, desenvolvendo um estudo longitudinal, onde se quantifica esta produção nos Hospitais, Centros de Saúde, Clínicas Médicas e Dentárias, Lares para Idosos, Postos Médicos de Empresas, Centros de Hemodiálise e Clínicas Veterinárias do Concelho da Amadora, e se compara esta produção em dois anos consecutivos; analisar as consequências do exercício do poder de Autoridade de Saúde na gestão integrada de RH pelas upcs; quantificar a produção média de RH, por acto prestado, nos cuidados domiciliários e, com um estudo analítico transversal, relacionar essa produção média com as características dos doentes e dos tratamentos efectuados; proceder à análise comparativa das definições e classificações de RH em países da União Europeia, através de um estudo de revisão da legislação nesta matéria em quatro países, incluindo Portugal. Resultados e Conclusões. Obtém-se a produção média de RH, por Grupos I+II, III e IV: nos Hospitais, por cama.dia, considerando a taxa de ocupação; por consulta, nos Centros de Saúde, Clínicas Médicas e Dentárias e Postos Médicos de Empresas; por cama.ano, nos Lares para Idosos, considerando a sua taxa de ocupação; e por ano, nas Clínicas de Hemodiálise e Veterinárias. Verifica-se que a actuação da Autoridade de Saúde, produz nas upcs uma diferença estatisticamente significativa no aumento das contratualizações destas com os operadores de tratamento de RH. Quantifica-se o peso médio de resíduos dos Grupos III e IV produzido por acto prestado nos tratamentos domiciliários e relaciona-se esta variável dependente com as características dos doentes e dos tratamentos efectuados. Comparam-se os distintos critérios utilizados na elaboração das definições e classificações destes resíduos inscritas na legislação da Alemanha, Reino Unido, Espanha e Portugal. Recomendações. Apresentam-se linhas de investigação futura e propõe-se uma reflexão sobre eventuais alterações de aspectos específicos no quadro legal português e nos planos de gestão integrada de RH, em Portugal. ABSTRACT The problem: The nature, diversity and hazardousness of hospital wastes (HW) requires specific procedures in its management. Its production depends on the number and patterns of healthcare services, number of patients, professional and administration practices and technologic innovations, among others. Integrated management of HW has been developping, in the scope of quality, for the past few years. There is a lack of information about the amount of HW produced in healthcare units and in the domiciliary visits, in Portugal. On the other hand, the Public Health Services, embracing the Health Authority’s power, play a very important role in managing the risk of HW production to public and environmental health. They need to use some indicators in its monitorization. In a country, rules and regulations define hospital waste management policies, which are confined by the addopted classification and definition of HW. Goals and Methods: This research study aims to quantify the production of HW as a result of healthcare services in human beings and animals, public service and private one. Through a longitudinal study, this production is quantified in Hospitals, Health Centers, Medical and Dental Clinics, Residential Centers for old people, Companies Medical Centers and Veterinary and Haemodyalisis Clinics in Amadora’s Council, comparing this production in two consecutive years. This study also focus the consequences of the Health Authority’s role in the healthcare services integrated management of HW. The middle production of HW in the domiciliary treatments is also quantified and, with a transversal analytic study, its association with patients and treatments’ characteristics is enhanced. Finally, the definitions and classifications in the European Union Countries are compared through a study that revises this matter’s legislation in four countries, including Portugal. Results and Conclusions: We get the middle production of Groups I+II, III and IV: HW: in Hospitals, by bed.day, bearing the occupation rate; by consultation, in Health Centers, Medical and Dental Clinics and Companies Medical Centers; by bed.year in Residential Centers for old people, considering their occupation rate; by year, in Veterinary and Haemodyalisis Clinics. We verify that the Health Authority’s role produces a significative statistical difference in the rise of the contracts between healthcare services and HW operators. We quantify the Groups III and IV’s wastes middle weight, produced by each medical treatment in domiciliary visits and relate this dependent variable with patients and treatments’ characteristics. We compare the different criteria used in the making of definitions and classifications of these wastes registered in German, United Kingdom, Spain and Portugal’s laws. Recommendations: Lines of further investigation are explaned. We also tender a reflexion about potential changes in rules, in regulations and in the integrated plans for managing hospital wastes in Portugal. RÉSUMÉ Le Problème. La gestion des déchets d'activités hospitalières (DAH) et de soins de santé (DSS) exige des procédures spécifiques en raison de leur nature, diversité et dangerosité. Leur production dépend, parmi d’autres, du nombre d’unités de soins de santé (USS), du type de soins administrés, du nombre de malades observés, des pratiques des professionnels et des organes de gestion des USS, de l’innovation technologique. La gestion intégrée des DAH et des DSS subit une évolution qualitative dans les dernières années. Il existe un déficit d’information sur les quantitatifs de DAH et de DSS provenant des USS et de la prestation de soins domiciliaires, au Portugal. D’autre part les Services de Santé Publique, y compris le pouvoir de l’Autorité de Santé, qui interviennent dans la gestion du risque pour la santé et pour l’environnement associé à la production de DAH et de DSS, ont besoin d’indicateurs pour leur surveillance. Dans cette matière le cadre légal établit la stratégie de gestion de ces déchets, laquelle est conditionnée par la classification et par la définition des DAH et des DSS adoptées par le pays. Objectifs et Méthodologie. Cet étude prétend: quantifier la production de DAH et de DSS provenant de la prestation de soins de santé, en êtres humains et animaux dans les USS du système public et privé. À travers un étude longitudinal, on quantifie cette production dans les Hôpitaux, Centres de Santé, Cliniques Médicales et Dentaires, Maisons de Repos pour personnes âgées, Cabinets Médicaux d’ Entreprises, Centres d’Hémodialyse et Cliniques Vétérinaires du municipe d’ Amadora, en comparant cette production en deux ans consécutifs; analyser les conséquences de l’exercice du pouvoir de l’Autorité de Santé dans la gestion intégrée des DAH et des DSS par les USS; quantifier la production moyenne de DAH et de DSS dans la prestation de soins domiciliaires et, avec un étude analytique transversal, rapporter cette production moyenne avec les caractéristiques des malades et des soins administrés; procéder à l’ analyse comparative des définitions et classifications des DAH et des DSS dans des pays de l’Union Européenne, à travers un étude de révision de la législation relative à cette matière dans quatre pays, Portugal y compris. Résultats et Conclusions. On obtient la production moyenne de DAH et des DSS, par Classes I+II, III et IV: dans les hôpitaux, par lit.jour, en considérant le taux d’occupation; par consultation, dans les Centres de Santé, Cliniques Médicales et Dentaires et Cabinets Médicaux d’ Entreprises par lit.an dans les Maisons de Repos pour personnes âgées en considérant le taux d’occupation; et par an, dans les Cliniques d’Hémodialyse et Vétérinaires. On constate que l’actuation de l’Autorité de Santé produit dans les USS une différence statistiquement significative dans l’accroissement de leurs contractualisations avec les opérateurs de traitement de DAH et de DSS. On quantifie le poids moyen des déchets des Classes III et IV produit par acte de prestation de soins à domicile et on rapporte cette variable dépendante avec les caractéristiques des malades et des soins administrés. On compare les différents critères utilisés dans l’élaboration des définitions et des classifications de ces déchets inscrites dans la légis

Nouvelles données sur la datation des dépôts miocènes de l’Algarve (Portugal), et l’évolution géologique regionale

This paper presents a resume of the results achieved by researchers of the Centro de Estratigrafia e Paleobiologia da U. N. L. on the Neogene of Algarve, since 1977. The detailed study of several profiles as well as that af calcareous nannoplanton, planktonic foraminifera, ostracoda, fishes and mammals allowed to obtain data and correlation elements leading to a new interpretation of the Miocene of Algarve. It was possible to date and to characterize the following units: a) Carbonate formation of Lagos-Portimão, of marine facies, ascribed to the Lower Miocene (Aquitanian? and mainly Burdigalian), possibly attaining the Lower Langhian. b) Essentially arenaceous series of continental facies with a marine intercalation of Arrifão, Olhos de Água and Auramar Hotel beach, middle Miocene (Langhian-Serravallian) in age. c) Marine (tripoli, conglomerates, sands and limestones) deposits of Tunes-Mem Moniz, Ponte das Lavadeiras (Faro), Arroteia (Fuzeta) and Luz de Tavira, corresponding, at least partially, to the first part of the upper Miocene (Lower Tortonian). d) Cacela formation with three members: The lower member (conglomerates and sands), the middle (yellow silts) and the upper ones (gray silts), uppermost Tortonian and mainly Messinian in age. An interpretation of the tectonic and paleogeographic evolution of the portuguese littoral during the Miocene is also presented considering its insertion in the meridional part of the Peninsula (Guadalquivir depression, Betic massif basins and in the spanish Levant in general). Comparisons among the Neogene vulcanism of this region and similar manifestations documented in Algarve (basanite of Figueira-Portimão, etc) are established.

Âges K-Ar de glauconites des environs de Luz de Tavira, Algarve

Glauconite K-Ar ages (6.88±0.4; 7.03±0.4 MY) confirm earlier reports to Upper Tortonian of silt beds near Morgadinho, Luz de Tavira and Tavira. Taking stratigraphical position and age into account it is possible now to correlate these beds with similar ones at Quelfes and Cacela (Formação de Cacela, lower member, ascribed to the upper part of N16 or to NI7 Blow's zone, Globorotalia humerosa - G. dutertrei; Tortonian to Messinian, according to the ostracod fauna). Limit between the above quoted zones is thus placed at about 7 MY. New K-Ar ages greatly improve the knowledge about Upper Miocene in eastern Algarve, and on regional tectonic evolution. This is particulary so in what concerns an intra-Tortonian phase.

Analyse paléoécologique des formations récifales du golfe de Skoura (bordure méridionale du sillon Sud rifain; SE de Fés; Maroc). Implications paléogéographiques: communications Atlantique - Méditerranée au Miocène Terminal

The reef levels of the gulf of Skoura belong to the reef formation of the Upper Miocene of the South-Rifan straits. A detailed analysis of the vertical distribution of various forms of colonies has led to the establishment of precise coral morphologies zonation. This palaeoecological approach leads us to distinguish between two environments in the Skoura gulf, probably corresponding to two reef episodes. The palaeogeographical implications (relationships between the Atlantic ocean and the Mediterranean sea) will be pointed out.

Répartition des foraminifères benthiques dans les gisements de surface du Miocène d'Aquitaine (SW de la France)

The Aquitaine Basin (southwestern France) is known since long ago for its richness in marine miocene deposits of various facies. A few stratotypes concerning this period have been described in the investigated area. The stratigraphical framework has been recently revised and the study of new exposures completes our knowledge on these levels. In the present work, the authors produce a biostratigraphical distribution of about 160 species (larger and smaller foraminifera), found in the surface exposures of Aquitaine, from the topmost Oligocene (Chattian) through to Middle Miocene (including Serravallian). As a rule, the common species without significant ranges have not bcen mentioned. The microfaunas of several exposures have been thoroughly revised, which has allowed to precise the distribution of many species and induced a few modifications of the results previously produced. Synonymy problems and new taxonomical revisions have been taken into account. Of course, this work will be probably submitted to some changes according to new research on the already known exposures or other more recently discovered.

Mots(dits) écrits:formes et valeurs de la diffusion des idées au 18ème siècle, au Portugal

Les rapports complexes entre les différentes façons de faire circuler les idées et les informations ne datent pas de nos jours. A toutes les époques, les messages qui circulent emploient toutes sortes de véhicules et de langages, très souvent complémentaires. Ces véhicules et ces langages n'ont peut-être rien d'extraordinaire. Ils appartiennent au monde des gestes de tous les jours, des gestes qui se répètent et dont la répétition est elle-même importante pour la construction du sens de chaque message. Ces gestes qui sont répétés, qui sont attendus et qui sont reconnus incluent des sons, des images, des comportements, des mots, ou des citations. Il y a donc un rapport qui s'y établit entre répétition et nouveauté, rapport dans lequel la répétition fournit chaque fois une nouvelle information, même si elle est déjà attendue, tandis que leur absence peut représenter l'anxiété, ou même le scandale.

Nouvelles données sur le Miocène moyen marin ("Sallomacien") de Gironde (Bassin d'Aquitaine-France) Approche des paléoenvironnements New data about the maine Middle Miocene ("Sallomacian") of Gironde (Aquitaine Basin); paleoecological outline

The Mid Miocene marine formations of Salles area (former "Sallomacian" stage) have been studied again from numerous outcrops and cores. The deep structural framework influences notably of the characteristics and distribution of the deposits, which are neritic. The stratigraphy is stated precisely thanks to the planktonic fauna and floradetailed examination (probably Serravallian zones NN6 - N12). Several paleobiofacies are reconstituted from the rich invertebrate faunas, which give also paleoclimatic data.

La biochronologie des Mammifères néogènes d'Europe. L'échelle MN, son application à la succession des faunes du Portugal

Similarly to other organisms, Vertebrates changed during the Cenozoic Era. Mammals are the only ones to change quickly; their well mineralised bones and teeth are often fossilised. They are highly diverse and even isolated teeth can be identified. They are thus a good tool for establishing a biochronological framewoork. Among Mammals, Rodents with a short lifetime evolve more quickly than the large Mammals. In Europe, the first elaborated zonation was investigated by the Regional Committee on Neogene Stratigraphy and issued as the MN Zonation (Mammals Neogene) by Mein, 1976. During the following years, progress in knowledge lead to new charts. The latest one resulted from collective work (de Bruijn et al., 1992). Bîochronology gives relative data; if we desire to have numerical age estimates, we must correlate these results with radiometrie data, marine biostratigraphîcal units or the Geomagnetic Polarity Time Scale. For Europe, these results are summarised by Steininger et al. (1989-1996) and Steininger (1999). After some recents developments on MN Zonation, here is discussed the succession of Neogene small mammals Portuguese localities. Fortunately these localities are in majority inbedded in marine context. Their assigment to MN Zones is proposed and correlations with the spanish Aragonian Scale (Daams el al., 1999) are also suggested. In fact, some differences appear between Portugal and Aragonian assemblages, probably for ecological reasons. Therefore, the MN zonation is always useful for short and long distance biochronological correlations.

Biostratigraphie et paléoécologie des peuplements d'ostracodes dans le Domérien du Bassin Lusitanien, Portugal

The Domerian sections from the Lusitanian Basin of São Pedro de Muel, Rabaçal and Tomar have provided us with more than 1100 Ostracods belonging from 18 genus and about 48 species. The faunal diversity and density of the associations decrease in space (from Tomar to Rabaçal and São Pedro de Muel) and time, with favourable environments for the proliferation of Ostracods at the lower part of the sections (Stokesi subzone) and more hostile at the upper part (Ragazzonii subzone). The Monestieri and Nitescens horizons and the Subnodosus subzone are characterized by a typical assemblage of Ostracods. The palaeoecological Ostracod indexes reveal the fluctuations of the oxygenation, temperature, depth and hydrodynamism of the water, on the different sections and on the whole platform. They display a diachronous cooling in the Lower Domerian series. In the upper part of the Middle and in the Upper Domerian, the deeper, less oxygenated and cooler waters prevent the development of the Ostracod faunas.

Atlas des fossiles caractéristiques du Lias portugais* III a) Domérien (Ammonites)

This fascicle, dedicated to the Domerian (Late Pliensbachian) ammonites faunas, is the third part of the “Atlas des fossiles caractéristiques du Lias portugais“. It follows two previous publications about the Hettangian-Sinemurian and the Carixian (Lower fifty species are concisely described and illustrated. The other groups (nautilids, belemnites, brachiopods, bivalvia...) will be published afterwards. The principal objective of the “Atlas des fossiles caractéristiques du Lias portugais“ is to make the main liassic lusitanian fossils known to a wide public. It also aims to support field studies by giving a rich iconography dedicated to the lusitanian invertebrate macrofaunas. In the case of the ammonites, all the species are described and the “Atlas” can be used as an exhaustive database for biostratigraphic and paleobiogeographic studies.

Exposição a fungos dos trabalhadores dos ginásios com piscina

RESUMO - Os trabalhadores dos ginásios com piscinas apresentam maior prevalência de lesões fúngicas, como a Tinea pedis e a onicomicose, devido às características intrínsecas da sua actividade profissional, pois apresentam mais horas por dia de exposição à contaminação fúngica das superfícies. Esta situação verifica-se não só por serem os que mais frequentam os locais possíveis de estarem contaminados, como é o caso de balneários, vestiários e zona envolvente às piscinas, mas também porque algumas das actividades desenvolvidas são realizadas com os pés descalços. Além disso, a utilização de roupa sintética e de calçado ocluso, que retêm a sudação excessiva, favorece o desenvolvimento fúngico. Constituiu objectivo deste trabalho conhecer o risco de infecção e/ou lesão (Tinea pedis e onicomicose) nos trabalhadores dos ginásios com piscina e a sua eventual relação com a exposição à contaminação fúngica (ar e superfícies) dos locais de trabalho. Foram descritas as variáveis ambientais e biológicas que influenciam a infecção e/ou lesão fúngica em ambiente profissional e exploradas eventuais associações entre essas mesmas variáveis. Foram também conhecidas as diferenças da contaminação fúngica das superfícies entre as duas principais estações do ano (Verão e Inverno) e entre antes e depois da lavagem e desinfecção. O estudo realizado possui uma componente transversal, em que se pretendeu descrever os fenómenos ambientais e biológicos da contaminação fúngica em ambiente profissional e explorar eventuais associações entre variáveis; uma componente longitudinal, em que foram conhecidas as diferenças sazonais da contaminação fúngica das superfícies; e, ainda, uma componente quase experimental, em que foi analisada a distribuição fúngica nas superfícies antes e depois da lavagem e desinfecção. Na vertente transversal foi considerada uma amostra de 10 ginásios com piscina e outra amostra de, pelo menos, 10 profissionais de cada estabelecimento, perfazendo um total de 124 trabalhadores (75 Homens - 60,48% e 49 Mulheres - 39,52%). Foram realizadas 258 colheitas biológicas aos pés dos trabalhadores, efectuada a avaliação ambiental da contaminação fúngica dos estabelecimentos através de 50 colheitas de amostras de ar e 120 colheitas de amostras de superfícies (60 antes e 60 depois da lavagem e desinfecção) e efectuados os respectivos processamento laboratorial e identificação fúngica. Foram também avaliadas as variáveis ambientais temperatura, humidade relativa e velocidade do ar, preenchidas 10 grelhas de observação, com o objectivo de efectuar o registo de informação sobre as variáveis que xx influenciam a exposição ocupacional às espécies fúngicas e, ainda, completadas 124 grelhas de observação inerentes à colheita de material biológico, de modo a realizar o registo dos profissionais com lesão e outras informações pertinentes para a análise laboratorial. Todos os 124 trabalhadores responderam a um questionário, em simultâneo à realização das colheitas biológicas, de modo a conhecer algumas das variáveis individuais e profissionais com pertinência para o presente estudo. Num dos estabelecimentos, foram também estudadas as diferenças da contaminação fúngica das superfícies entre antes e depois da lavagem e desinfecção e, ainda, entre as duas estações do ano (Verão e Inverno). Nesse estabelecimento, foram realizadas 36 colheitas de superfícies antes e 36 colheitas depois da lavagem e desinfecção, em 6 dias diferentes da semana, durante 6 semanas sequenciais em cada estação do ano, completando um total de 72 colheitas de superfícies. Foi ainda criado e aplicado um método para estabelecer um padrão de exposição profissional a fungos nas superfícies, de modo a permitir definir níveis semi-quantitativos de estimação do risco de infecção fúngica dos trabalhadores dos ginásios com piscinas. Para o critério da Gravidade, considerou-se que a gravidade da contaminação e, consequentemente, da possível lesão, está intimamente relacionada com a espécie fúngica envolvida. Foram calculadas as médias da contaminação fúngica por cada estabelecimento antes da lavagem e desinfecção, de modo a estabelecer os níveis de Frequência e, em relação à Exposição, foram estabelecidos intervalos para agrupar as horas semanais de trabalho. Dos 124 trabalhadores que participaram no estudo, 58 (46,8%) possuíam lesões visíveis. Nesses 58, as Leveduras foram as mais isoladas (41,4%), seguidas dos Dermatófitos (24,1%) e de Fungos Filamentosos Não Dermatófitos (6,9%). Candida parapsilosis e Rhodotorula sp. foram as Leveduras mais frequentemente isoladas (20,2%); no caso dos Dermatófitos, Trichophyton rubrum foi a espécie mais frequente (55,5%) e, relativamente aos Fungos Filamentosos Não Dermatófitos, Penicillium sp. foi o mais isolado (15,6%), seguido do género Fusarium (12,5%). No que concerne à contaminação fúngica das superfícies, 37 fungos filamentosos foram isolados. Fusarium foi o género mais frequente, antes e depois da lavagem e desinfecção (19,1% - 17,2%). Em relação aos fungos leveduriformes, 12 leveduras diferentes foram identificadas, tendo sido os géneros Cryptococcus (40,6%) e Candida (49,3%) os mais frequentes antes e depois da lavagem e desinfecção, respectivamente. Em relação à contaminação fúngica do ar, foram identificados 25 fungos filamentosos diferentes, em que os 3 géneros mais frequentemente isolados foram Cladosporium (36,6%), Penicillium (19,0%) e Aspergillus (10,2%). Relativamente às leveduras, foi identificado o género xxi Rhodotorula (87,5%) e as espécies Trichosporon mucoides e Cryptococcus unigutulattus (12,5%). Verificou-se associação, ao nível de significância de 5%, entre lesão visível e horas semanais e entre lesão visível e tempo de profissão, comprovando a influência da duração da exposição ao factor de risco (contaminação fúngica do ambiente profissional), para a presença de lesão visível nos trabalhadores expostos (Tinea pedis e onicomicose), ficando demonstrada a relação entre a exposição ao factor de risco em estudo – exposição profissional a fungos – com os efeitos para a saúde. As variáveis ambientais avaliadas (temperatura, humidade relativa e velocidade do ar) não influenciaram a contaminação fúngica do ar e das superfícies, não tendo sido evidenciada nenhuma relação estatisticamente significativa (p>0,05). Contudo, verificou-se influência do número de ocupantes que frequentaram cada um dos estabelecimentos nas médias das unidades formadoras de colónias por metro quadrado nas superfícies antes da lavagem e desinfecção. Não se verificou correlação entre os resultados quantitativos da contaminação fúngica do ar e a das superfícies dos 10 estabelecimentos monitorizados. No entanto, verificaram-se diferenças significativas, ao nível de significância de 10%, entre a contaminação fúngica das superfícies e a contaminação fúngica do ar (p<0,1), tendo-se constatado que apesar de 50% dos valores mais baixos terem sido superiores na contaminação fúngica do ar, a contaminação fúngica das superfícies apresentou-se com maior variabilidade quantitativa. Em relação às diferenças significativas na contaminação fúngica das superfícies nos 10 estabelecimentos entre antes e depois da lavagem e desinfecção, apenas se verificou redução significativa (p<0,05) da contaminação fúngica depois da lavagem e desinfecção nos balneários e vestiários masculinos em relação aos fungos leveduriformes. No estabelecimento seleccionado, verificou-se que a relação entre a contaminação fúngica e a temperatura e humidade relativa não foi significativa (p>0,05) em ambas as estações do ano e também não se constatou influência dos ocupantes nos valores médios das unidades formadoras de colónias por metro quadrado das superfícies antes da lavagem e desinfecção em ambas as estações de ano. Em quase todas as situações em que se verificaram diferenças significativas entre as duas estações do ano, verificou-se um aumento das unidades formadoras de colónias por metro quadrado no Inverno, com excepção do total das unidades formadoras de colónias por metro quadrado antes da lavagem e desinfecção nos balneários e vestiários masculinos em que se verificou aumento no Verão. Constatou-se também que apenas ocorreu redução da xxii contaminação fúngica depois da lavagem e desinfecção nas escadas de acesso no Inverno e nos balneários e vestiários masculinos no Verão. Com a aplicação do método para estabelecer um padrão de exposição profissional a fungos nas superfícies obteve-se, nos 10 estabelecimentos, com Nível de Risco Mínimo 65 locais (54,2%), com Nível de Risco Médio 23 locais (19,2%) e com Nível de Risco Elevado 32 locais (26,6%). Próximo do jacuzzi e junto ao tanque foram os locais com mais classificações de Nível de Risco Elevado. No estabelecimento seleccionado verificou-se que, no Verão, depois da lavagem e desinfecção, ocorreu um maior número de locais classificados no Nível de Risco Elevado e, no Inverno, constatou-se a situação inversa, tendo sido observado maior número de locais com Nível de Risco Elevado antes da lavagem e desinfecção. Junto ao tanque e nas escadas de acesso à zona envolvente ao jacuzzi e tanque foram os locais com mais classificações de Nível de Risco Elevado, no Verão e no Inverno. Foram isolados nas superfícies fungos comuns aos isolados nos trabalhadores. Antes da lavagem e desinfecção, 30,3% dos fungos foram isolados nas superfícies e nos trabalhadores e depois desses procedimentos 45,5% dos fungos foram também isolados comummente. As Leveduras foram as mais isoladas comummente e as que se verificaram mais frequentes antes e depois da lavagem e desinfecção da superfícies e, também, nos resultados das colheitas biológicas realizadas aos trabalhadores, foram o género Rhodotorula e a espécie Candida parapsilosis, permitindo confirmar que a infecção fúngica dos trabalhadores está relacionada com a contaminação fúngica das superfícies. Concluiu-se que é necessária a intervenção em Saúde Ocupacional no âmbito da vigilância ambiental e da vigilância da saúde, com o intuito de diminuir a prevalência das infecções fúngicas. Para a prossecução desse objectivo, sugere-se a implementação de medidas preventivas, nomeadamente: o controlo da contaminação fúngica das superfícies mediante procedimentos de lavagem e desinfecção eficazes, de modo a minimizar a contaminação fúngica das superfícies; a identificação precoce da infecção através da realização de colheitas biológicas periódicas aos trabalhadores, inseridas num protocolo de vigilância da saúde; e, ainda, a sensibilização para a aplicação de medidas de higiene pessoal e o tratamento das patologias. A aplicação do método criado para estabelecer um padrão de exposição profissional a fungos nas superfícies servirá não só para a estimação do risco de infecção fúngica dos trabalhadores de ginásios com piscinas, mas também para facilitar o estabelecimento de valores fúngicos de referência, a implementação de medidas correctivas adequadas e imediatas e, ainda, a prevenção de infecções fúngicas, não só nos ginásios com piscina, mas também noutros contextos profissionais. ------------ SUMMARY - Gyms with swimming pools workers have higher prevalence of fungal injuries, such as Tinea pedis and onychomycosis. This is due to their work intrinsic characteristics, since they have more hours per day of exposure to surfaces fungal contamination. This occurs not only because they attend sites most likely to be contaminated, such as showers, changing rooms and pool surrounding area, but also because some of the activities are done barefoot. Furthermore, synthetic clothing and occluded footwear use, which retain the excessive sweating, promotes fungal development. The aim of this study was to know gymnasiums with swimming pool workers infection and/or injury (Tinea pedis and onychomycosis) risk, and its possible relationship with exposure to workplace fungal contamination (air and surfaces). This study describes environmental and biological variables that influence infection and/or fungal injury in a professional setting and explored possible associations between these variables. Differences in surfaces fungal contamination between the two main seasons (summer and winter), as well between before and after cleaning and disinfection were known. It was developed a study with an cross-sectional perspective, that aimed to describe the biological and environmental phenomena of fungal contamination in a professional environment and explore possible associations between variables; an longitudinal perspective in which were known surfaces fungal contamination seasonal differences; and also with an almost experimental perspective that analyzed surfaces fungal distribution before and after cleaning and disinfection. The cross-sectional perspective comprised 10 gyms with swimming pool sample, and another sample of, at least, 10 professionals in each establishment totalling 124 workers (75 men – 60,48%, and 49 women – 39,52%). Were performed 258 biological samples at workers feet, environmental fungal contamination evaluation from the establishments through 50 air samples and 120 surfaces samples (60 before and 60 after cleaning and disinfection) and conducted their laboratory processing and fungal identification. Were also evaluated environmental variables, such as temperature, relative humidity and air velocity completed 10 observation grids, in order to obtain data about variables that affect occupational exposure to fungal species, and also completed 124 observation grids inherent to biological material collection, in order to know the professionals with injury and other relevant information for laboratory analysis. All 124 workers answered to a questionnaire at the same time that occur biological samples collection, in order to xxv obtain information about some of the individual and professional variables with relevance to this study. In one of the establishments were also studied differences concerning surfaces fungal contamination between before and after cleaning and disinfection, and also between two main seasons (summer and winter). In this setting, there were performed 36 surfaces samples before and 36 surfaces samples after cleaning and disinfection on 6 different week days for 6 sequential weeks in each season, totalling 72 surfaces samples. It was also created and implemented a method to establish a pattern for surfaces fungal occupational exposure, in order to help define semi-quantitative levels estimation to fungal infection risk in gyms with swimming pools workers. For Gravity criterion it was considered that contamination severity and, thus, the possible injury are closely related to implicate fungal species. Was calculated fungal contamination average by each establishment prior cleaning and disinfection, in order to establish Frequency levels. Regarding Exposure, were established weekly hours group intervals spent in professional activity. From the 124 professionals tested, 58 (46,8%) had visible injuries. In the 58 workers, Yeasts were the most isolated (41,4%), followed by Dermatophytes (24,1%) and Other Filamentous Fungi Besides Dermatophytes (6,9%). Candida parapsilosis and Rhodotorula sp. were the most frequently isolated Yeasts (20,2% for each), from Dermatophytes, Trichophyton rubrum was the most frequently isolated species (55,5%) and from Other Filamentous Fungi Besides Dermatophytes, Penicillium sp. was the most frequent (15,6%), followed by Fusarium genera (12,5%). Regarding surfaces fungal contamination, 37 filamentous fungi were isolated. Fusarium genera was the most frequent, before and after cleaning and disinfection (19,1% - 17,2%). Considering yeasts, 12 different yeasts were identified, being Cryptococcus (40,6%) and Candida (49,3%) genera the more frequent before and after cleaning and disinfection, respectively. In relation to air fungal contamination, 25 different filamentous fungi were identified and the 3 most frequently isolated genera were Cladosporium (36,6%), Penicillium (19,0%) and Aspergillus (10,2%). For yeasts, were identified Rhodotorula genera (87,5%), and also the species Trichosporon mucoides and Cryptococcus unigutulattus (12,5%). Was found association with 5% significance level, between visible injury and weekly hours and between visible injury and occupation time, confirming exposure duration influence to risk factor (work environment fungal contamination) for the visible injury presence in exposed workers (Tinea pedis and onychomycosis), being confirmed the relation between the study exposure risk - occupational exposure to fungi - with health effects. xxvi Environmental variables evaluated (temperature, relative humidity and air velocity) did not affect air and surfaces fungal contamination and wasn’t found no statistically significant relation (p>0,05). However, there was evidence that occupant’s number influence surfaces colony forming units mean per square meter before cleaning and disinfection. There was no correlation between quantitative data from air fungal contamination and surfaces fungal contamination from the 10 establishments monitored. However, there were significant differences with 10% significance level, between surfaces and air fungal contamination (p<0,1), and despite 50% of the lowest rates were higher in air fungal contamination, it was found that surfaces fungal contamination had more quantitative variability. Regarding differences from the 10 establishments surfaces fungal contamination, between before and after cleaning and disinfection, there was only a significant reduction (p<0,05) in fungal contamination after cleaning and disinfection in male changing rooms for yeasts. In the selected establishment, it was found that relation between fungal contamination and temperature and relative humidity was not significant (p>0,05) in both seasons, and also there wasn’t no influence observed from occupants in surfaces colony forming units mean per square meters before cleaning and disinfection in both seasons. In almost all situations where significant differences between the two seasons were shown, there was a colony-forming units per square meter increase in winter. There was an exception in total colony forming units per square meter before cleaning and disinfection in male changing room’s exception, where there was an increase in summer. Furthermore, was found that only occur a reduction in fungal contamination after cleaning and disinfection, on access stairs in winter, as well as in male changing rooms in summer. With application from the method to establish pattern for surfaces fungal occupational exposure, it was obtained, in the 10 establishments, 65 sites with Low Risk Level (54,2%), 23 sites with Average Risk Level (19,2%) and 32 sites with High Risk Level (26,6%). Near swimming pool and jacuzzi were the places with more High Risk Level classifications. In the selected establishment, was found that in the summer, after cleaning and disinfection, there were a greater number of sites classified as High Risk Level, and in winter it was found the opposite situation, being noted more places with High Risk Level before cleaning and disinfection. Next to swimming pool and access stairs to swimming pool and jacuzzi were the places with more High Risk Level classifications in Summer and Winter. Were isolated common fungi in surfaces and in workers. Prior to cleaning and disinfection 30,3% of fungi were isolated on surfaces and workers, and after 45,5% of fungi were also xxvii commonly isolated. The Yeasts were the most commonly isolated and the most frequent before and after surfaces cleaning and disinfection, and also in workers biological samples, were Rhodotorula genera and Candida parapsilosis, allowing confirming that workers fungal infection is related with surfaces fungal contamination. It was concluded that Occupational Health intervention it is necessary, in environmental monitoring and health surveillance perspective, in order to reduce fungal infections prevalence. To achieve this objective, preventive measures implementation it’s recommended, including: surfaces fungal contamination control, through effective cleaning and disinfecting in order to minimize surfaces fungal contamination; early infection identification by performing periodic biological sampling from workers, included in a health surveillance protocol; and also personal hygiene and diseases treatment awareness. Application of the created method to establish pattern for surfaces fungal occupational exposure, will be useful not only for estimating workers from gymnasiums with swimming pools fungal infection risk, but also to facilitate fungal reference values stipulation, effective and corrective measures implementation, and also, fungal infections prevention, not only in gymnasiums with swimming pool, but also in other professional settings.----------------- RÉSUMÉ - Les travailleurs des gymnases avec des piscines présentent souvent des infections fongiques, telles que Tinea pedis et aussi des onychomycoses, dues à leur activité professionnel, parce qu’ils restent plus longtemps tout prés des surfaces avec une certaine contamination fongique. Toute cette situation est due non seulement parce qu’ils sont ceux qui fréquentent plus souvent les places plus contaminées: des balnéaires, des vestiaires et des zones autour des piscines, mais aussi ils réalisent des activités aux pieds nus ou avec des chaussures très fermés et encore quelques fois avec des vêtements synthétiques. Tout cela emmène à une grande sudation ce qui aidera au développement fongique. Un objective de ce travaille a été connaître le risque d’infection et/ou présence de lésion (Tinea pedis et des onychomycoses) dans les travailleurs des gymnases avec des piscines et leur éventuel rapport avec l’exposition à la contamination fongique (de l’air et des surfaces) dans leurs locaux de travaille. On a décrit aussi des variables d’environnement et biologiques qui ont une certaine influence dans les infections fongiques dans tout l’environnement professionnel et aussi approfondir des éventuels associations entre ces même variables. On a encore reconnu des différences de la contamination fongique avant et après des lavages et désinfection de ces surfaces. Aussi on a trouvé des différences de contamination en Été et en Hiver. Cet étude a un composante transversale, en visant la description des phénomènes de contamination fongique biologique et de l'environnement dans un environnement professionnel et l’étude des associations possibles entre les variables; une composante longitudinale dans laquelle ils étaient connus comme des variations saisonnières de la contamination fongique des surfaces, et même; un quasi-composante expérimentale, où elle a examiné la répartition des champignons surfaces avant et après le lavage et la désinfection. Dans la composante transversale on été considérés 1 échantillons de 10 gymnases avec des piscines et un autre échantillon de au moins 10 professionnels de chaque établissement dans un total 124 travailleurs (75 hommes - 60,48% et 49 femmes - 39,52%). On a réalisé 258 prélèvements aux pieds des travailleurs et on a effectué en simultané la validation par contamination fongique de l’environnement par 50 prélèvements de l’air et par 120 prélèvements de surfaces (60 avant et 60 après des lavages et des désinfections) et on a effectué leur traitement en laboratoire et l’identification fongique. On a fait aussi l’évaluation des variables de l’environnement, la température, l’humidité relative et la vitesse de l’air. On a remplie 10 tableaux xxix d’observation, avec l’objective d’obtenir des informations sur les variables qu’influenceront l’exposition occupationnel aux souches fongiques, et encore 124 tableaux d’observation liée au prélèvement du matériel biologique, pour réaliser le registre des professionnels avec des lésions et des autres informations pertinentes pour une analyse laboratoire. Tous ces 124 travailleurs ont rempli un questionnaire au même temps que les prélèvements biologiques, afin de connaître quelques variables individuels et professionnels importants pour cet étude. Dans un des établissements on a aussi étudié les différences fongiques des surfaces parmi avant et après les lavages et de la désinfection et encore parmi l’Été et l’Hiver. Dans ce même établissement on a réalisé 36 prélèvements des surfaces avant et 36 après des lavages et de la désinfection, pendant 6 jours différents de la semaine, pendant 6 semaines en chaque saison de l’année, dans un total de 72 prélèvements des surfaces. On a encore crié et appliqué une méthode pour établir un standard d’exposition professionnelle au fungi sur les surfaces, afin de permettre la définition des niveaux semi quantitative d’estimation des risques d’infection fongique des travailleurs des gymnases avec des piscines. Pour le critère de Gravité, il a été considéré que la gravité de la contamination, et donc les possibles dommages, est étroitement liée aux espèces fongiques impliquées. Nous avons calculé la moyenne de la contamination fongique par chaque établissement avant le lavage et la désinfection afin d'établir les niveaux de Fréquence et, par rapport à l'Exposition, ont été crées pour regrouper les intervalles d'heures hebdomadaires consacrées à l'activité professionnelle en question. Sur les 124 travailleurs qui ont participé à l'étude, 58 (46,8%) avaient des lésions visibles. Parmi ces 58, les Levures ont été les plus isolées (41,4%), suivis par des Dermatophytes (24,1%) et des Filamenteux Non Dermatophytes (6,9%). Candida parapsilosis and Rhodotorula sp. ont été les Levures les plus fréquemment isolées (20,2%); dans le cas des Dermatophytes, Trichophyton rubrum est le plus fréquent (55,5%) et pour les Filamenteux Non Dermatophytes, Penicillium sp. a été le plus isolé (15,6%), suivi par Fusarium sp. (12,5%). En ce qui concerne la contamination fongique des surfaces, 37 champignons filamenteux ont été isolés. Le genre Fusarium est le plus fréquent avant et après le lavage et la désinfection (19,1% - 17,2%). Pour la levure, 12 levures différentes ont été identifiées, ayant été Cryptococcus sp. (40,6%) et Candida sp. (49,3%) les plus fréquents avant et après le lavage et la désinfection, respectivement. En ce qui concerne la contamination fongique de l'air, on a identifié 25 différents champignons filamenteux, où les 3 genres les plus fréquemment isolés étaient Cladosporium (36,6%), Penicillium (19,0%) et Aspergillus (10,2%). Pour les levures, il a été identifié le genre xxx Rhodotorula (87,5%) et les espèces Trichosporon mucoides et Cryptococcus unigutulattus (12,5%). On a vérifié une association, au niveau de signification de 5%, entre les lésions visibles et les heures hebdomadaires et entre les lésions visibles et la durée d’occupation, ce qui confirme l'influence de la durée de l'exposition aux facteurs de risque (contamination fongique dans le milieu de travail) pour la présence des lésions visibles chez les travailleurs exposés (Tinea pedis et onychomycose), en démontrant une relation entre l'exposition au facteur de risque dans ces études - l'exposition professionnelle aux champignons - avec les effets sur la santé. Les variables environnementales évalué (température, humidité relative et la vitesse de l'air) ne modifient pas la contamination fongique de l'air et des surfaces; donc, n'a pas été démontré aucune relation statistiquement significative (p>0,05). Cependant, il y a une influence du nombre d'occupants qui ont participé à chacun des établissements en moyenne des unités formant colonie par mètre carré sur la surface avant le lavage et la désinfection. Il n'y avait pas de corrélation entre les résultats quantitatifs de la contamination fongique de l'air et des surfaces des 10 établissements surveillés, cependant il existe des différences importantes, au niveau de signification de 10% entre la contamination fongique des surfaces et de la contamination fongique de l'air (p <0,1), on a constaté que malgré 50% des niveaux les plus bas étaient plus élevés dans la contamination fongique de l'air, la contamination fongique des surfaces présentée une plus grande variabilité quantitativement. En ce qui concerne les différences de la contamination fongique des surfaces dans les 10 établissements entre avant et après le lavage et la désinfection, il y avait seulement une réduction significative (p<0,05) de la contamination fongique après le lavage et la désinfection dans les balnéaires et vestiaires pour les hommes par rapport aux levures. Lors de l'établissement choisi, on a constaté que le rapport entre la contamination fongique et la température et l'humidité relative n'était pas significatif (p>0,05) dans les deux saisons et aussi on n’a pas observé l'influence des occupants en moyenne des unités formant colonie par mètres carrés de surfaces avant le lavage et la désinfection dans les deux saisons de l'année. Dans presque toutes les situations ou on a vérifié des différences significatives entre les deux saisons, il ya eu une augmentation des unités formant des colonies par mètre carré en Hiver, à l'exception du total des unités formant des colonies par mètre carré avant le lavage et désinfection dans les balnéaires et vestiaires des hommes où il y a eu une augmentation en Été. On a également été constaté que seulement a eu une réduction de la contamination des xxxi champignons après la désinfection de l'escalier d'accès en Hiver et dans les balnéaires et vestiaires des hommes en Été. Avec la méthode pour établir standard d’exposition professionnelle au fungi sur les surfaces on a obtenu dans les 10 établissements, avec le Niveau de Risque Faible de 65 places (54,2%), avec le Niveau de Risque Moyen 23 places (19,2%) et 32 places avec le Niveau de Risque Élevé (26,6%). Près du jacuzzi et près de la piscine sont les lieux avec des plus évaluations de Niveau de Risque Élevé. Lors de l'établissement choisi, il a été constaté que, dans l'Été, après le lavage et la désinfection, un plus grand nombre de places évaluées comme présentant un Niveau de Risque Élevé et en Hiver on a constaté la situation inverse avec de nombreux points de Niveau de Risque Élevé avant le lavage et la désinfection. A côté de la piscine et les escaliers ont été les lieux avec plus grands classifications de Niveau de Risque Élevé en Été et en Hiver. On a isolé, chez les travailleurs, des champignons communs aux isolés sur les surfaces. Avant le lavage et la désinfection, 30,3% des champignons ont été isolés sur les travailleurs et sur les surfaces et, après ces procédures, 45,5% des champignons ont été isolés fréquemment. Les levures les plus souvent isolées et les plus fréquentes avant et après le lavage et la désinfection des surfaces, et aussi dans les résultats d'échantillons biologiques prélevés sur les travailleurs, étaient du genre Rhodotorula et les espèces de Candida parapsilosis, ce qui permet confirmer que l'infection fongique des travailleurs est liée à la contamination fongique des surfaces. On a conclu qu’il est nécessaire l'intervention en Santé Occupationnelle sous la surveillance de l'environnement et sous la surveillance de la santé, afin de réduire la prévalence des infections fongiques. Pour atteindre cet objectif, nous suggérons la mise en oeuvre de mesures préventives, y compris: le contrôle de la contamination fongique des surfaces par des méthodes de lavage et de désinfection afin de minimiser la contamination fongique des surfaces, l'identification précoce de l'infection avec des prélèvements biologiques périodiques, notamment un protocole pour la surveillance de la santé, et aussi la conscience du sens de l'hygiène personnelle et le traitement des pathologies. La méthode mise en place pour l’établissement d’un standard d’exposition professionnelle au fungi sur les surfaces, servira à estimer non seulement le risque d'infection fongique des travailleurs dans les gymnases avec des piscines, mais aussi pour faciliter l'établissement de valeurs de référence de champignons, l'application des mesures correctives immédiates et appropriées, et aussi la prévention des infections fongiques, non seulement dans les gymnases avec piscine, mais aussi dans d'autres contextes professionnels.
