Resposta clínica periodontal e controle glicêmico em pacientes com e sem diabetes tipo II portadores de periodontite crônica ao tratamento periodontal “full mouth desinfection”

There is a bidirectional association between periodontal disease (PD) and diabetes mellitus, in which diabetes favors the development of PD and PD, if left untreated, can worsen the metabolic control of diabetes. Thus, periodontal disease should be treated to restore periodontal health and reduce the complications of diabetes. Therefore, the objective is assess the effect of full mouth periodontal therapy decontamination (Full Mouth Desinfection - FMD) in diabetic type II patients with chronic periodontitis during 12 months. Thirty-one patients in group one (G1) and 12 in group two (G2) were followed at baseline, 03, 06 09 and 12 months. There following clinical parameters were accessed: probing on bleeding (BOP), visible plaque index (PI), probing depth (PD), clinical attachment level (CAL) and gingival recession (GR). For diabetic patients, there were also made laboratory tests to evaluate blood parameters: fasting glucose and glycated hemoglobin. The results had been analyzed in two ways: all sites in the mouth and another with diseased sites. The Mann-Whitney, Friedman and Wilcoxon tests were used with 5% significance. Intergroup analysis of all sites it is clear that there was no significant difference over time concerning PD, BOP, PI, CAL and RG. However, when evaluating the diseased sites, we observed significant difference for CAL and PD, with higher values in G1. The intragroup analysis for all sites showed a statistically significant reduction at PD, PI and BOP in both groups. Intragroup analysis of periodontal affected sites showed a statistically significant reduction in PD, BOP and CAL in both groups. There was also a statistically significant increase in RG values. There was no significant change concerning glycated hemoglobin and fasting glucose in the G1. Therefore, it can be concluded that there were improvements in periodontal parameters over the 12 months of research, but without changes in glycemic levels of diabetic patients. Thus, periodontal therapy proved effective in maintaining oral health.

Avaliação do desempenho de argamassas à base de cimento Portland para rejuntamento de placas cerâmicas tipo II com adição de pó de borracha de pneus

In this work it is assessed the performance of Portland cement-based mortar to the grouting of type II ceramic plates with the addition of unusable tire rubber powder. It is presented a bibliographical review about the subject in which is done the theoretical and methodological foundation of the whole investigative process. The analyzed universe comprises a sample of mortar to the grouting of conventional ceramic plates type II (reference sample) and five more samples to the grouting of ceramic plates type II, which were made up of the addition of unusable tire rubber powder in the respective proportion (in mass) of 4%, 8%, 12%, 16% and 20%. These mortar samples were subject to the trials of determination of the consistency index (Brazilian Standard NBR 13276:2005), water retention ( Brazilian Standard NBR 14992 Attachment B:2003), permeability in 240 minutes (Brazilian Standard NBR 14992 Attachment G:2003), absorption of water by immersion (Brazilian Standard NBR 9781:2013), resistance to compression (Brazilian Standard NBR14992 Attachment D: 2003), resistance to traction in the flexion (Brazilian Standard NBR 13279:2005), resistance of traction adherence (Brazilian Standard NBR 14081 part 4:2012) and hardened mass density (Brazilian Standard NBR 13280: 2005). It has been found out from the analyzes of the results in the trial the following situation: the reference mortar used met the established requirements in the norms of specifications corresponding to only six from the eight parameters assessed in the research; the mortar with addition of 4,0% of tire rubber powder met the established requirements corresponding to only the resistance to compression and the resistance of adherence to traction. Thus, the other kinds of mortar with addition of 8,0 %, 12,0 %, 16,0 % and 20,0 % of tire rubber powder met the requirements of specifications corresponding to only the resistance to compression and the resistance of adherence to traction. This result concludes that the adding of tire rubber powder does not grant improvement to the mortar of type II grouting to the laying of ceramic plates.

Incidência e fatores de risco da retinopatia diabética em pacientes do Hospital Universitário Onofre Lopes, Natal-RN

Estudar a incidência e fatores de risco (tempo de doença e presença de hipertensão arterial sistêmica) para retinopatia diabética em 1002 pacientes encaminhados pelo Programa de Diabetes do Hospital Universitário Onofre Lopes no período de 1992 – 1995. Métodos: Estudo retrospectivo de pacientes com diagnóstico de diabetes mellitus encaminhados ao Setor de Retina do Departamento de Oftalmologia pelo Programa de Diabetes do Hospital Universitário e submetido, sob a supervisão do autor, a exame oftalmológico, incluindo medida da acuidade visual corrigida (tabela de Snellen), biomicroscopia do segmento anterior e posterior, tonometria de aplanação e oftalmoscopia binocular indireta sob midríase(tropicamida 1% + fenilefrina 10%). Foi realizada análise dos prontuários referente ao tempo de doenças e diagnostico clínico de hipertensão arterial sistêmica. Resultados: Dos 1002 diabéticos examinados (em 24 deles a fundoscopia foi inviável), 978 foram separados em 4 grupos: sem retinopatia diabética (SRD), 675 casos (69,01%); com retinopatia diabética não proliferativa (RDNP), 207 casos (21,16%); com retinopatia diabética proliferativa (RDP), 70 casos (7,15%); e pacientes já fotocoagulados (JFC), 26 casos (2,65%). Do total, 291 eram do sexo masculino (29%) e 711 do sexo feminino (71%). Os 4 grupos foram ainda avaliados quanto ao sexo, a faixa etária, a acuidade visual, tempo de doença, presença de catarata e hipertensão arterial sistêmica e comparados entre si. Com relação ao tipo de diabetes, 95 eram do tipo I (9,4%), 870 pacientes eram do tipo II (86,8%), e em 37 casos(3,7%) o tipo de diabetes não foi determinado. Conclusões: Comprovou-se que os pacientes com maior tempo de doença tinham maior probabilidade de desenvolver retinopatia diabética, e que a hipertensão arterial sistêmica não constituiu fator de risco em relação à diminuição da acuidade visual nos pacientes hipertensos

Construção de bibliotecas de cDNAs subtraídos a partir das sementes de Mamona submetidas à estresse hídrico e análise in silico de transcritos potencialmente expressos sob condições de estresse: Metalotioneina, proteína reprimida por auxina de 12.5 kDa e Glutelina tipo-A3

Estresses ambientais abióticos são fatores que causam respostas ao nível molecular, fisiológico e morfológico em plantas, dependendo também de sua intensidade e duração. É visto que algumas espécies apresentam tolerância a condições estressantes e ao mesmo tempo são fontes naturais de matéria prima para indústria. Nesse contexto encontra-se a mamona (Ricinus comunnis L.), principal fonte de óleo de rícino valorizado por suas aplicações farmacêuticas e principalmente industriais, vem sendo usada como cultura em regiões onde a disponibilidade de água é reduzida, usada como fonte de renda para agricultura da região nordeste brasileira. Visto que pouco se sabe sobre as respostas moleculares que levam essa planta a tolerar regiões secas e como as sementes, principais foco de interesse, respondem a essa escassez, nesse trabalho foram construídas duas bibliotecas de cDNAs, onde a partir de uma abordagem subtrativa, continham RNAs diferencialmente expressos em sementes de plantas mamona submetidas ao estresse hídrico durante 5 dias (biblioteca L7), e a outra RNAs diferencialmente expressos em sementes controle (biblioteca L5). A biblioteca L7 apresentou a maior variedade de transcritos com um total de 182. A maior parte das funções estabelecidas pelo sistema Gene Ontology - GO, foram direcionadas aos “Processos Metabólicos” (526), em segundo “Respostas a estímulos” (57), o terceiro termo mais abundante foram referentes a “Desenvolvimento”(26). Já na biblioteca L5, foram encontrados 91 transcritos, com maior parte de suas funções referentes a “Processos Metabólicos”(413), em segundo “Respostas a estímulos” (8) e em terceiro Regulação (6). Alguns dos transcritos da biblioteca L7 foram escolhidos para análise por repetirem-se mais de 3x e não aparecerem na biblioteca L5, o que indica uma possível regulação positiva sobre estresse. As análises sobre Metalotioneína (4x), mostraram que a sequência de proteica apresentava os domínios conservados que a caracterizava como tipo II, onde são encontrados dois domínios funcionais ricos em cisteína com posições altamente conservadas, desempenhando a função de ligar-se a metais pesados, correlacionadas assim como a atividade de eliminação EROs e defesa contra o estresse oxidativo, além de apresentar homologia com a sequência de Bruguiera gymnorhiza, uma planta de mangue adaptada a ambientes salinos. Analisamos também os transcritos da referente a proteína AUXIN-REPRESSED 12.5 KDA (3x), apontada como sendo reprimida pelo hormônio auxina e associada ao processo de dormência da semente, é descrito em uma família gênica onde vários membros pertencem as vias de resposta ao estresse. Por último, analisamos a proteína GLUTELIN TYPE-A 3 (5x), uma importante proteína de armazenamento com caráter hidrofílico, possivelmente direcionada para o vacúolo. Em nosso trabalho foi possível observar um aumento de transcritos em relação a subtração controle, possivelmente reflexo do aumento do metabolismo da semente, tanto para resposta defensiva ao estresse hídrico quanto para o amadurecimento rápido da semente onde foram observados transcritos referentes a resposta oxidativa, controle hormonal, proteínas de reserva e produção de óleo.

Anormalidades cardiovasculares e metabólicas em pacientes com a síndrome de Berardinelli - SEIP

A Síndrome de Berardinelli-Seip (SBS) ou Lipodistrofia Generalizada Congênita acomete freqüentemente o aparelho cardiovascular e também promove anormalidades metabólicas envolvendo os metabolismos glicídico e lipídico. O objetivo do nosso trabalho foi avaliar a prevalência das anormalidades cardiovasculares e metabólicas em portadores da SBS. Vinte e dois pacientes do estado do Rio Grande do Norte (Brasil), com diagnóstico da SBS, foram submetidos à avaliação clinica, eletrocardiograma de repouso, ecodopplercardiograma, radiografia de tórax, eletrocardiografia dinâmica de 24 horas, teste ergométrico e análise laboratorial. Os pacientes eram predominantemente adultos jovens (n=22) , sendo 14 do sexo feminino. O mais novo tinha 8 e o mais velho 44 anos(22,4±9,7 anos). A totalidade da amostra apresentou resistência à insulina, acanthosis nigricans e HDL-colesterol diminuído. A presença de esplenomegalia, hepatomegalia, diabetes mellitus tipo II e triglicérides elevados eram constantes. A síndrome metabólica foi caracterizada em 81,8% dos pacientes com predominância para sexo feminino e com um alto grau de consangüinidade paterna (86,4%). A hipertensão arterial sistêmica e pré-hipertensão foram encontradas em mais da metade dos pacientes (77.3%). O eletrocardiograma e a radiografia de tórax não foram úteis para identificar a presença de anormalidades cardíacas na SBS, em particular a presença de hipertrofia ventricular esquerda. Para identificar o acometimento cardiovascular foi indispensável o estudo ecodopplercardiografico. Este exame mostrou a presença de hipertrofia concêntrica do ventrículo esquerdo (50%), hipertrofia excêntrica do ventrículo esquerdo (4,5%) e geometria normal do ventrículo esquerdo (45,5%). Disfunção sistólica do ventrículo esquerdo foi encontrada em apenas um paciente (4,5%) e disfunção diastólica em nenhum. Elevada taxa de arritmia foi evidenciada no Holter, tais como, extra-sístoles ventriculares, extra-sístoles supraventriculares e taquicardia supraventricular sustentada. Incompetência cronotrópica (54,5%) foi observada no teste ergométrico. Anormalidades cardiovasculares e metabólicas foram encontradas em elevada prevalência em indivíduos jovens e assintomáticos com SBS. Esses achados xii apontam para a necessidade de acompanhamento cardiológico sistemático e de medidas preventivas nesse grupo de risco

O elo microbiano como alimento alternativo para o zooplâncton em reservatórios dominados por cianobactérias

Protozoa may be an important alternative food source for Calanoida copepods in these environments. Aiming to quantify the feeding preferences of N. cearensis by ciliates in the presence of cyanobacteria, in vitro experiments were conducted, using mixed cultures in different concentrations of total food for copepod. Two ciliates species (Paramecium sp. and Cyclidium sp.) and a cyanobacteria toxic strain (Microcystis aeruginosa) were offered as food. Previous experiments were done to identify the copepod s maximum ingestion rate through the use of a type II functional response model when each prey is offered separately. High maximum ingestion rate were found when those protists were offered as prey. N. cearensis showed significant preference for protozoal prey over the cyanobacterium tested both in low (corresponding 95.15% of the diet) and in high food concentration treatments (about 91.56% of the diet), preferring the bigger ciliate in lower concentrations (67.52% of the diet). The meaningful involvement of heterotrophic organisms in the zooplankton diet emphasis the microbial loop participation in the energy transition from copepods to higher trophic levels. This data contributes to understand the stability of existing trophic interactions in reservoirs subjected to eutrophication and assists trophic cascade studies in these environments

Propriedades ópticas de nanocristais de SiGe: efeitos de dopagem e desordem

We have used ab initio calculations to investigate the electronic structure of SiGe based nanocrystals (NC s). This work is divided in three parts. In the first one, we focus the excitonic properties of Si(core)/Ge(shell) and Ge(core)/Si(shell) nanocrystals. We also estimate the changes induced by the effect of strain the electronic structure. We show that Ge/Si (Si/Ge) NC s exhibits type II confinement in the conduction (valence) band. The estimated potential barriers for electrons and holes are 0.16 eV (0.34 eV) and 0.64 eV (0.62 eV) for Si/Ge (Ge/Si) NC s. In contradiction to the expected long recombination lifetimes in type II systems, we found that the recombination lifetime of Ge/Si NC s (τR = 13.39μs) is more than one order of magnitude faster than in Si/Ge NC s (τR = 191.84μs). In the second part, we investigate alloyed Si1−xGex NC s in which Ge atoms are randomly positioned. We show that the optical gaps and electron-hole binding energies decrease linearly with x, while the exciton exchange energy increases with x due to the increase of the spatial extent of the electron and hole wave functions. This also increases the electron-hole wave functions overlap, leading to recombination lifetimes that are very sensitive to the Ge content. Finally, we investigate the radiative transitions in Pand B-doped Si nanocrystals. Our NC sizes range between 1.4 and 1.8 nm of diameters. Using a three-levels model, we show that the radiative lifetimes and oscillator strengths of the transitions between the conduction and the impurity bands, as well as the transitions between the impurity and the valence bands are strongly affected by the impurity position. On the other hand, the direct conduction-to-valence band decay is practically unchanged due to the presence of the impurity

Aspectos anatômicos do olho e neuroquímicos da retina do mocó (Kerodon rupestris)

The visual system is an important link between the animal and the environment, com profound influences on the habits and lifestyle in various habitats. Adaptive mechanismsto the temporal niche are present in the visual system of many vertebrates, involving changins in ocular dimensios and design, retinal cell distribution and organization of neurochemical circuits related to the retinal resolution or sensitivity. The sensory system of the eye is represented by the retina, whose organization is responsible by receipty, initial analysis, and transmission of the information to the brain. The knowledge of the position of the eyes in the head and the distribution of retinal cells allow to identify adaptive aspects of each species to its visual field, which is characteristic to the ecological niche it occupies. In this research, we study eye anatomical characteristics and retina neurochemical features of the rock cavy (Kerodon rupestris), a tipical Brazilian rodent from the suborder Hystricomorpha, family Caviidae. The rock cavy has lateral eyes well constitute bony orbit and well differentiated extrinsic muscle. The study of the descriptive and morphometric anatomy of the showed mean values of axial diameter 10.7±0,5mm and equatorial diameter 11.6±0.7mm. The pupil is slit shaped and the lens has mean axial diameter 5.4±0.03 mm, corresponding to ~45% of the axial diameter of the eye. The posterior nodal distance and the retinal magnification factor were estimated at 6.74 mm e 118 μm/grau, respectively. Flat mounts were processed for Nissl stain, and the topographic distribution of ganglion cells showed a moderate visual band, just below the optic disc, with higher density in the ventral retina. Retinal vertical sections and flat mounts were processed for immunohistochemistry to visualize tyrosine hydroxilase (TH) and thus two types of TH+ cells were detected. Type 1 cells had strong TH-immunoreactivity, the body cell varied from 120.047 to 269.373 μm2 stratifying in the sublamina 1 of the IPL. Type 2 cells were weakly TH-imunoreactive, had cell body located mostly in the IPL, varying from 54.848 to 177.142 μm2, constituting ~10% of the TH+ cells. Both cell types exhibited similar topographic distribution with higher density found in a horizontal band along of the naso-temporal axis in the dorsal retina. The total population of dopaminergic cells was 2,156±469,4 cells, occupying an average area of 198,164 μm2. The presence of cones and rods was detected by immunohistochemistry in vertical sections and flat mounts. S cones density is around 10 times smaller than L cones, with different degree of spatial organization. Other retinal neuronal populations of the rock cavy were also detected in vertical sections with specific markers. Comparative analysis of the anatomical characteristics of the rock cavy eye 12 suggest that it was designed to acquire higher sensitivity to light, at expense of image sharpness, compatible with a vision at mesopic conditions. Additionally, the distribution of the 2 subtypes of dopaminergic cells in a naso-temporal band in the dorsal retina seems suitable to a gain in sensitivity, coherent with an animal with predominantly crepuscular activity pattern

Envelhecer entre pássaros e anjos: um estudo etnográfico sobre o processo saúde doença do idoso no contexto familiar

Study, a descriptive-like one, is guided by ethnographic principles which have analyzed the elderly within the familiar context in his/her process of health and aging, in the neighborhood called Felipe Camarão, located in the western administrative region of Natal, RN, a Northeastern city of Brazil. The participants are elders aging 61 to 84 years old, living in this referring neighborhood, whose majority is constituted of migrants from the rural region of the state of the RN, retired, including widows, widowers and married couples, with low school-educational degree. For the information gathering it was utilized a semi-structured interview, the participant observation and the field diary, being put into effect, in majority, in the houses and in the Family Health Unit, in a period between March and October of 2006. For the results discussion it was utilized an analysis of thematic content and the program ALCESTE (In Portuguese, Análise Léxica por Contexto de um Conjunto de Segmentos de Texto or Lexical Analysis by Context of a Set of Text Segments), which through have emerged two corpus: the corpus I, Family and the elderly, and corpus II, The elderly and the aging within society. The analysis of the results has permitted to conclude that the family, also used by the public policies as a strategy of their practices in health, it is a necessary base support for the elderly citizen in his/her process of aging and of health. The elders familiar contexts have allowed this study to identify the existence of minimal social conditions of life, of new rearrangements of the current families by means of the plurigenerational acquaintanceship and the active presence of the elderly woman as a maintainer of this family; also by means of conflicted relationships among one another but in a bearable level of acquaintanceship. Different conceptions about the aging and the elderly generate disagreement and divergency however the family support and help for the solving of these problems and the attention to health are proceeding from the family components. However, it is noticed that loneliness is something present in these elder s everyday lives. About the attention to health, in a basic level of it, it was noticed that there are still a lot of gaps, mainly concerning promotional and preventing actions, deserving a higher sensitization and effort by the local health institutions

Prevalência de doença arterial obstrutiva periférica (DAOP) e alterações sensoriais em pacientes diabéticos tipo 2: impacto da DAOP sobre a qualidade de vida, nível de atividade física e composição corporal

Diabetes Mellitus (DM) affected approximately 171 million people in the world in the year 2000 as described by the World Health Organization (WHO). Because DM is a multisystem disease it can cause several complications especially those related to the cardiovascular system. The Peripheral Arterial Disease (PAD) of the lower limbs and the Diabetic Distal Symmetric Polyneuropathy (DDSP) can affect the DM patient causing consequences as the diabetic foot and eventually amputations. The main objective of this study was to determine the prevalence of PAD and sensorial impairment in 73 type 2 DM (DM2) patients and also assess the impact of PAD on quality of life, level of physical activity and body composition. For clinical assessment it was used: the ankle-brachial index (ABI); quantitative sensorial test for tactile sensibility (ST), pain (SD), vibration (SV); Achilles tendon reflex (RA); quality of life questionnaire (SF-36); modified Baecke physical activity questionnaire and bioelectric impedance. Prevalence of PAD in the studied population was 13.7%. ABI was inversely correlated to age (p=0,03; rhô= -0,26), diabetes duration (p=0,02; rhô= -0,28) and blood pressure (p= 0,0007; rhô= -0,33). There were lower scores for physical health summary on the SF-36 in DM2 patients; however, the presence of PAD predominantly mild did not significantly impact quality of life, body composition or physical activity level assessed by questionnaire. Fourteen patients (19.2%) present bilateral and symmetrical alterations in two or more sensorial tests compatible to DPN diagnosis. Abnormalities in ST, SD and SV were present in 27.3%, 24.6% and 8.2%; respectively. There was association of results from ST abnormalities with RA and mainly with SD, suggesting the importance of 10g monofilament use in DM2 routine assessment. In conclusion, the prevalence of PAD in subclinical DM2 was slightly higher compared to the general population and in agreement to previously published data in DM patients. The PAD severity was predominantly mild and still without repercussion on quality of life and body composition. Our study demonstrated a significant prevalence of both PAD and DPN in DM2 without previous diagnosis of these complications and indicates the necessity of early preventive and therapeutic interventions for this population

Tecendo vivências e sentidos do câncer infantil : família, doença e redes de apoio social em Natal-RN

This paper discusses the experiences related to the treatment of children´s cancer which had children, their mothers and families as their main characters. They were mainly originated from areas in the countryside and urban poor areas in the State of Rio Grande do Norte. The non-governmental organization Grupo de Apoio à Criança com Câncer (GACC) was the privileged ethnographic location. In this setting, the mother, which was called acompanhante (companion), and the children, defined as pacientes (patients), were often sheltered in reason of therapeutic practices and the treatment undertaken by children in a nearby hospital. This study aims to focus on the therapeutic itinerary, beyond the children´s suffering, dealing with the family as a whole, since the moral values from these popular families imply the complete involvement of the family in relation to the illness and its treatment. Therefore, it is experienced as a family problem. We also intend to understand the construction of meanings to the illness, dealing with the ideological continuity in the relationships between the families and the GACC. These meanings were built in the intersection of these two spheres, which refer particularly to medical, religious and emotional explanations. Ethnographic methods were applied in this research at the entity and another social contexts, such as the family households. I also tried to retrieve the process of treatment outside the GACC, visiting the family context, when doing dense interviews or just having conversations with informants. It was found that the GACC, as a non-governmental organization, generates a negotiation of identities, which develops, then, through the family as a whole, but also through the child and especially the mother, affecting, in some way, their internal organization. Furthermore, the meanings of the experience of illness appeared to be shaped by the family sphere as well as by the logic of public health structures

Análise bioclimática do bairro do Renascença II São Luis-MA: realidade e perspectiva do conforto térmico em espaços externos

The present research concerns about outdoor s thermal comfort conditions in hot-humid climate cities, understanding that life quality is a result of the urban object s type built for the human being in an environment with specific climate and morphological characteristics. It is presented as object of study the correlation between the neighborhood Renascença II s microclimate in São Luis /MA-Brazil, hot-humid climate city, and its urban morphological changes. As well as the thermal comfort s satisfaction level of its outdoor users. The research has as general goal to diagnosis the way these transformations caused by the urbanization influence the Renascença II s microclimate, identifying critical spots of the studied area, in order to contribute with land use recommendations based on bioclimatic architecture concepts and supply bases to urban design decisions adequate to the São Luis climate. It is presented as theoretical bases the urban climate, its concepts and elements. After that, the thermal comfort conditioners and its prediction models of thermal comfort sensation in outdoor are presented. The predictive models are presented along with bioclimatic assessment methods. Finally the use of bioclimatic assessment as an effective tool to identify places that need changes or preservation in order to seek environment quality. The applied methodology was based on the studies of Katzschner (1997), complemented by Oliveira s (1988) and Bustos Romero s (2001) studies that suggest an analysis and evaluation of maps of topography, buildings floors, land use, green areas and land covering, in order to overlap their characteristics and identify climate variable s measurements points; then a quantitative analysis of the climate variables (air temperature and humidity, wind speed and direction) of the chosen points takes place. It was perceived that Renaissance II has no permanence areas as squares or parks, its outdoor has little vegetation and presets high land impermeability and built density levels. The majority of the people interviewed said that was comfortable in a range of air temperature between 27,28ºC and 30,71ºC. The elaboration of a neighborhood master plan is important, which defines strategies for improvement of the life quality of its inhabitants

Barracas de Praia, praia de barracas: configuração, tipo e usos na praia do futuro, Fortaleza CE

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.
